Description of the Invention: [Technical Field] The present invention relates to a brushing device having a cam structure, and more particularly to a brushing device suitable for a winding type motor. 5 ❹ 10 15 20 [Prior Art] - Generally speaking, in places where the starting torque is large, such as crane cranes or mining areas where high-powered machines are required, the tools must be wound-type motors to meet the requirements. The demand for horsepower. The winding type motor also has the following advantages: the starting current can be reduced by the secondary starting resistor, the starting torque can be increased by the secondary starting resistor, the required switching capacity is small, the starting process is smooth, and the small range can be used. Speed control is thus widely used by industry. The brushing mechanism required in the conventional winding type motor is a multi-link design, and the multi-link design method has a low rigidity and load carrying capacity of the overall mechanism, and can only be used for a maximum current of 400 amps. Winding motor. Moreover, because the driving method is driven by a multi-link connection, the position accuracy at the end working point is also low when it is actuated, which is not ideal, and there is still room for improvement. It can be seen from the above how to achieve a mechanism for simplifying the brushing device, improve the rigidity of the brushing device, and reduce the transmission loss, so as to effectively improve the performance and bearing capacity of the brushing device, thereby making the brushing movement accurate and smooth. It is an urgent need in the industry. 4 201025801 The inventor's reason is that in the spirit of active invention and creation, he thought of a "cam structure brushing device" that can solve the above problems, and finally completed the present invention after several research experiments. 5 SUMMARY OF THE INVENTION The present invention relates to a brushing device having a cam structure, which is assembled in a winding type motor, and the brushing device comprises: a motor spindle, a slip ring, a carbon brush holder group, a drive unit, a drive shaft, a first sprocket wheel, and a second cam plate. The above-mentioned slip ring system is sleeved outside the motor main shaft, and the plurality of conductive plates are arranged on the slip ring. The carbon brush holder group is spanned on the slip ring ±. The driving device is fastened. It is disposed at one end of the transmission shaft, and the driving device can drive the transmission shaft to rotate. As for the first cam disc and the second cam disc, they are sleeved on the drive shaft and are coupled together. 15 The first cam link is provided with a first connecting rod, and the first connecting rod is provided with an insulating sleeve, and the insulating sleeve is provided with a plurality of short-circuiting rings corresponding to the plurality of conductive plates of the slip ring. . As for the second cam disc, there is a set of lifting rods located below the carbon brush holder group. Wherein, the driving device is capable of driving the transmission shaft to rotate, so that the driving shaft rotates at an angle of 20 degrees at a first position and a second position. When the rotation angle of the transmission shaft is in the first position, that is, the transmission shaft, the first cam plate, and the second cam plate are in the original position 'not yet rotated', the plurality of short-circuit rings on the insulating sleeve are not engaged on the slip ring. The plurality of conductive plates, and the carbon brush holder group is also in contact with the slip ring, that is, the winding type motor is not short-circuited. 5 201025801 When the driving shaft rotation angle is in the second position, that is, when the driving device drives the transmission shaft to rotate to the second position, the first cam disc rotates at an angle to drive the first connecting rod to slip, thereby promoting the insulating sleeve It also follows the slip, so that the plurality of short-circuit rings are engaged with the plurality of conductive plates. And the second cam disc rotates at an angle of 5 at the same time to drive the rod to slide, thereby causing the carbon brush holder group not to contact the slip ring, so that the winding type motor is short-circuited. Thereby, the invention can simplify the mechanism of the brushing device, improve the rigidity of the brushing device, and reduce the transmission loss thereof, thereby effectively improving the parameter performance and the bearing capacity of the brushing device, and is applicable not only to a large winding type motor, And it makes ίο brush movements precise and smooth. Further, the above-described driving device may be an electric deceleration motor, a hydraulic actuator, a pneumatic actuator, or other equivalent driving device. In addition, the other end of the transmission shaft can be sleeved with a hand wheel, a rotating rod, or other equivalent structure. When the power of the driving device fails, 15 is manually operated. Furthermore, the second cam disc may further comprise a second connecting rod, and the second Φ connecting rod is further provided with a lifting rod, so that the second connecting rod can drive the lifting rod to slide up and down. 20, further, the first link on the first cam plate can drive the plurality of short-circuit rings on the insulating sleeve to slide left and right, and the 俾 can be engaged with the plurality of conductive plates on the slip ring to make the winding motor Is in a short circuit. In addition, the switch may further include a cam and a micro switch. Preferably, the wheel train is sleeved on the drive shaft and interlocked together, and the micro-moving disc cam is correspondingly disposed and electrically connected to the driving device, and is driven by the drive. 6 201025801 The rotation angle of the first set and the micro switch control drive shaft, the position, or the second position. In addition, the carbon brush holder group may include a six-carbon brush holder brush holder #, each of the carbon brush holders may include a spring, and the spring may be used to contact the slip ring with the carbon brush holder group, and [Embodiment] 10 15
