Description

Technical Field

[0001] This invention belongs to the field of electric tool firing pin processing technology, and more specifically, relates to an outer surface processing device for electric tool firing pins. Background Technology

[0002] Polishing effectively removes minor defects, burrs, and scratches from the surface of power tool strikers after machining, reducing surface roughness and making the surface smoother. This not only improves the appearance quality of the striker but also reduces friction with other parts, enhances wear resistance, and thus extends service life. Polishing also creates residual compressive stress on the surface, improving fatigue resistance and ensuring the stability and reliability of the striker during high-speed movement.

[0003] The current caliper polishing equipment still has the following problems: 1. Usually, one end of the caliper is clamped by a fixture before polishing, which makes it impossible to polish the entire surface of the caliper in one go. Multiple clamping affects the polishing efficiency of the caliper; 2. It cannot guide the polished caliper, which means that the polished caliper still needs to be removed manually by the staff, which also affects the polishing efficiency of the caliper. Summary of the Invention

[0004] This disclosure relates to an outer surface processing device for power tool strikers, comprising a striker processing component, a striker support component, a striker moving component, and a striker guide component. When two servo motors b are working, two circular clamping rods drive the power tool striker to rotate, achieving automatic polishing of the outer surface of the power tool striker. After the polished power tool striker contacts the striker guide frame, the striker guide frame moves downward movably, allowing the polished power tool striker to elastically contact the striker guide frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the two servo motors a are working, the output shafts of the two servo motors a drive the two circular drive rods to rotate; when the two circular drive rods rotate, the two impact pin processing frames and the two impact pin polishing belts rotate automatically, realizing the automatic polishing of the power tool impact pins.

[0017] 2. The two circular mounting shafts of this invention enable the two movable support plates to rotate, ensuring that the power tool striker can pass through the two movable support plates after being subjected to force; when the power tool striker passes through the two movable support plates, the two movable support plates can automatically return to their original positions under the action of two return springs.

[0018] In addition, the four circular limiting rings limit the front and rear positions of the two movable support plates; the four limiting slots and four limiting blocks limit the angle of the two movable support plates after they are reset, so that the lower ends of the two movable support plates are directly below the striker of the power tool to be polished.

[0019] 3. The two mounting sliders of this invention enable the two electric telescopic rods to move in tandem with the two mounting sliders; when the dual-axis motor rotates forward, the two mounting sliders drive the two electric telescopic rods to move inward simultaneously; when the dual-axis motor rotates in reverse, the two mounting sliders drive the two electric telescopic rods to move outward simultaneously.

[0020] Furthermore, when the two mounting sliders move the two electric telescopic rods inward simultaneously, the two circular clamping rods automatically clamp the power tool striker to be polished; when the output shafts of the two electric telescopic rods retract, the two circular clamping rods move the power tool striker downward, achieving automatic contact between the power tool striker and the two striker polishing strips; when the two servo motors b are working, the two circular clamping rods drive the power tool striker to rotate, achieving automatic polishing of the outer surface of the power tool striker; when the two mounting sliders move the two electric telescopic rods outward simultaneously, the polished power tool striker automatically separates from the two circular clamping rods.

[0021] 4. The four circular guide shafts of this invention allow the firing pin guide to slide along the four circular guide shafts; the four helical springs allow the firing pin guide to move downwards after the polished power tool firing pin contacts the firing pin guide, so that the polished power tool firing pin can make elastic contact with the firing pin guide, thereby improving the service life of the firing pin guide.

[0022] In addition, the circular drive shaft allows the rectangular control plate to change angles, which controls the discharge direction of the power tool striker after polishing; when the two servo motors c are working, the circular drive shaft drives the rectangular control plate to rotate automatically, realizing the automatic adjustment of the rectangular control plate angle.

[0055] The specific usage and function of this embodiment are as follows:

[0056] In use, the rectangular mounting base 101 is first fixed to the metal bracket with bolts. Then, two ejector pin collection boxes are placed on the left and right sides of the rectangular mounting base 101, ensuring that the polished power tool ejector pins 500 can fall into one of the collection boxes. Next, an external robotic arm is also bolted to the metal bracket, positioned behind the rectangular mounting base 101. The robotic arm intermittently and automatically places the power tool ejector pins 500 to be polished. Two servo motors a104 are started. When the two servo motors a104 are working, their output shafts drive... The two circular drive rods 103 rotate; when the two circular drive rods 103 rotate, the two impact pin processing frames 105 and the two impact pin polishing belts 106 rotate automatically; the dual-axis motor 301 is started, causing the dual-axis motor 301 to rotate forward. At this time, the two mounting sliders 302 drive the two electric telescopic rods 304 to move inward simultaneously. When the two mounting sliders 302 drive the two electric telescopic rods 304 to move inward simultaneously, the two circular clamping rods 307 automatically clamp the power tool impact pins 500 to be polished. The two electric telescopic rods 304 are started, causing the output shafts of the two electric telescopic rods 304 to retract. Two circular clamping rods 307 drive the power tool striker 500 downwards, achieving automatic contact between the power tool striker 500 and the two striker polishing belts 106. After being subjected to force, the power tool striker 500 can pass through the two movable support plates 203. When the power tool striker 500 passes through the two movable support plates 203, the two movable support plates 203 automatically reset under the action of two return springs 204.

The outer surface of the 00 is automatically polished; then the dual-axis motor 301 is controlled to reverse. At this time, the two mounting sliders 302 drive the two electric telescopic rods 304 to move outward simultaneously. When the two mounting sliders 302 drive the two electric telescopic rods 304 to move outward simultaneously, the polished power tool striker 500 automatically separates from the two circular clamping rods 307. After the polished power tool striker 500 contacts the striker guide 402, the striker guide 402 moves downward flexibly, so that the polished power tool striker 500 can make elastic contact with the striker guide 402, thereby improving the service life of the striker guide 402.When it's necessary to change the discharge direction of the polished power tool ejector pin 500, the operator starts two servo motors c407. When the two servo motors c407 are working, the circular drive shaft 405 drives the rectangular control plate 406 to rotate automatically, achieving automatic adjustment of the angle of the rectangular control plate 406. At this time, the polished power tool ejector pin 500 enters another ejector pin collection box. Then, the operator removes the ejector pin collection box full of polished power tool ejector pins 500 and replaces it with a new one, avoiding machine downtime and ensuring the processing efficiency of the power tool ejector pin 500.
