Heat Dissipating Architecture For Machine Tools
View pageUS Patent:
8226454, Jul 24, 2012
Filed:
Dec 7, 2009
Appl. No.:
12/632350
Inventors:
Bach Pangho Chen - Claremont CA, US
Assignee:
X'Pole Precision Tools Inc. - Chung-Li, Taoyuan County
International Classification:
B24B 23/03
US Classification:
451 7, 451357, 451449
Abstract:
A heat dissipating architecture for a machine tool is provided. The machine tool includes an accommodating space, a tool shaft mounted in the accommodating space, a counter balancing mass having a first balancing portion and a second balancing portion mounted on the tool shaft for causing an eccentric rotation stroke of the tool shaft, and an inlet communicating with the accommodating space. The heat sink is mounted on the counter balancing mass. The heat sink includes a first blade portion corresponding to the first balancing portion, a second blade portion corresponding to the second balancing portion, and a linking portion for connecting the first and second blade portions, such that during the rotation stroke of the tool shaft, the heat sink inhales air via the inlet, transmit the air from the first blade portion to the second blade portion, and then exhausts the air from the second blade portion.

B24B 3/00
US Classification:
361704, 173217, 361707, 361715, 361719, 451488
Abstract:
A machine tool with a heat conduction structure comprises a machine tool and a heat dissipation seat installed on the machine tool. The machine tool has a handle. The handle has an accommodation space accommodating a circuit board and having an opening at one end. The heat dissipation seat has a heat dissipation member arranged on the opening and a carrying member connected with the heat dissipation member and extended to the accommodation space. The carrying member carries the circuit board, contacts heat sources of the circuit board, and conducts heat to the heat dissipation member. As the machine tool is exempted from forming heat dissipation holes on the handle, the present invention can effectively prevent dust from entering the handle and damaging the circuit board. Further, the present invention can dissipate heat generated by the circuit board and maintain normal operation of the circuit board and the machine tool.

8276684, Oct 2, 2012
Filed:
Oct 1, 2010
Appl. No.:
12/896300
Inventors:
Bach Pangho Chen - Claremont CA, US
Assignee:
X'Pole Precision Tools Inc. - Chung-Li, Taoyuan County
International Classification:
B25F 5/02
US Classification:
173171, 173170, 1731621, 16430, 74522, 74523
Abstract:
A machine tool with an auxiliary cushion structure includes a machine tool having a grip portion and a trigger switch mounted on the grip portion. The grip portion has a control lever pivotally mounted thereon to enable the control lever to rotate against the grip portion, so as to press the trigger switch during rotation and drive the machine tool to operate. The grip portion further has an auxiliary cushion mounted thereon and a gap is formed between the auxiliary cushion and the control lever. The auxiliary cushion has a supporting surface which is tilted upwards from one end close to the control lever to the other end. Thus no matter the control lever is pressed by the operator or released, the operator's hand can rest on the supporting surface to alleviate or ease the fatigue.
Negative Pressure Dust Collection Structure For Power Tools
View pageUS Patent:
8382559, Feb 26, 2013
Filed:
Apr 9, 2010
Appl. No.:
12/757533
Inventors:
Bach Pangho Chen - Claremont CA, US
Assignee:
X'Pole Precision Tools Inc. - Chung-Li, Taoyuan County
International Classification:
B24B 55/06
US Classification:
451456, 451350, 451353, 451357, 451359
Abstract:
A negative pressure dust collection structure aims to be used on a power tool which is coupled with an application tool operable in a working space surrounded by a dust collection hood. The dust collection hood includes at least one flow conduction vent communicating with an airflow duct through a negative pressure enhancing duct. The negative pressure enhancing duct has a negative pressure enhancing chamber communicating with the flow conduction vent. The negative pressure enhancing chamber is formed at a cross section shrunk gradually from the flow conduction vent towards the airflow duct to increase suction of the negative pressure enhancing duct to collect dust in the dust collection hood. Moreover, the negative pressure enhancing chamber has an opening edge mating the shape of the inner side of the wall of the dust collection hood to increase covering range of the airflow.
Dust-Proof Structure For Machine Tools
View pageUS Patent:
8435096, May 7, 2013
Filed:
Aug 19, 2010
Appl. No.:
12/859600
Inventors:
Bach Pangho Chen - Claremont CA, US
Assignee:
X'Pole Precision Tools Inc. - Chung-Li, Taoyuan County
International Classification:
B24B 23/00
B24B 55/02
B24B 55/02
US Classification:
451 7, 451357
Abstract:
A dust proof structure for a machine tool includes a flow guiding element located therein. The machine tool includes a housing chamber to hold a spindle and the flow guiding element. The housing chamber has an air intake section and an air discharge section communicating with the air intake section. The machine tool further has an air inlet communicating with the air intake section and an air outlet communicating with the air discharge section. The spindle is coupled with an action member outside the air outlet. When the spindle drives the action member to operate, the flow guiding element introduces external air through the air inlet to the air intake section, and directs the air to the air discharge section to be discharged towards the action member. Hence dust generated by the action member during operation of the machine tool does not enter the machine tool through the air outlet.

Thereby during operation of the machine tool, dust can be prevented from entering the machine tool through the driving switch and the aperture to maintain steady operation of the machine tool and enhance the lifespan thereof.
Heat Dissipation Structure For Sealed Machine Tools
View pageUS Patent:
20100327675, Dec 30, 2010
Filed:
Jun 26, 2009
Appl. No.:
12/492157
Inventors:
Bach Pangho Chen - Claremont CA, US
International Classification:
H02K 7/14
H02K 9/02
H02K 9/02
US Classification:
310 50, 310 60 A
Abstract:
A heat dissipation structure for sealed machine tools includes a motor rotor rotating to drive airflow to perform heat dissipation simultaneously. It includes a machine tool housing with a heat dissipation vent and a chamber inside, a stator in the chamber and a rotor located between the stator and the housing. The rotor and the housing wall form a swirling flow space between them. The rotor and the stator form an axial flow space between them. The swirling flow space and the axial flow space communicate through a radial airflow passage. The rotor has at least one flow directing portion. The rotor rotates relative to the stator. The stator generates thermal airflow which flows from the axial flow space through a radial airflow passage to the swirling flow space. The flow directing portion performs an exchange of cooling air and thermal airflow through the heat dissipation vent.
Power Control Structure For Electric Power Tools
View pageUS Patent:
20110278035, Nov 17, 2011
Filed:
May 12, 2010
Appl. No.:
12/778600
Inventors:
Bach Pangho CHEN - Claremont CA, US
International Classification:
B27C 3/08
US Classification:
173170
Abstract:
A power control structure aims for an electric power tool which gets an input power from an electric power source and converts the input power to a driving power to drive an electric motor. The electric power tool further includes a manual control means, a magnetic control element and a power modulation circuit. The manual control means includes a trigger portion movable by depressing of a user and a magnetic element movable with the trigger portion. The magnetic control element outputs an output control signal in proportion to alterations of a magnetic field caused by movements of the magnetic element. The power modulation circuit gets the input power and modulates to the driving power controlled by the output control signal to drive the electric motor. Thus by depressing the trigger portion, output power of the electric motor can be controlled to provide precise control of rotational speed and torque alterations.
