The surface of the electrode cap will be worn during use. At this time, the electrode cap needs to be ground to ensure the welding quality of the electrode cap.

[0003] The electrode cap grinding device will generate metal scraps when grinding the electrode cap. When performing the next electrode cap grinding, if there is still metal scraps left on the inside of the electrode cap grinding device, the metal scraps will be mixed between the grinding knife and the electrode cap. The obstruction of the metal scraps will cause the grinding knife to be unable to grind the electrode cap directly, resulting in uneven grinding, which affects the grinding effect of the electrode cap and requires the cleaning operation of the metal scraps after each grinding.

[0031] In the disclosed embodiment, the lower end of the lower coil spring 203 is fixedly connected to the main grinding frame 1, the grinding rotary frame 2 is slidably connected to the main grinding frame 1, and the outer cam 202 is slidably connected to the main grinding frame 1. After the pole cap moves up and the grinding rotary frame 2 is separated, the lower coil spring 203 supports the outer cam 202 and the grinding rotary frame 2 to move up. The lower coil spring 203 also supports the outer cam 202 and the grinding rotary frame 2 to perform excess rebound vibration. The grinding rotary frame 2 and the grinding tool 3 vibrate synchronously, and the grinding tool 3 shakes off the waste chips generated by grinding.

[0032] In the disclosed embodiment, the grinding rack 2 and the grinding tool 3 are both located above the lower waste chip collection box 103, and the lower parts of the grinding rack 2 and the grinding tool 3 are connected to the lower waste chip collection box 103. The lower coil spring 203 also supports the outer cam 202 and the grinding rack 2 to perform excess rebound vibration. The grinding tool 3 vibrates and shakes off the metal waste generated by grinding, and the waste shaken off by the grinding tool 3 falls into the lower waste chip collection box 103 for collection.

[0033] Embodiment 2, on the basis of embodiment 1, the bottom of the grinding main frame 1 is connected to an electric four-wheel mobile conveyor, so that the grinding main frame 1 can be moved back and forth with the electric four-wheel mobile conveyor to the vicinity of the welding robot that needs grinding, so as to meet the grinding operation of the welding robot. At the same time, there is no need to set a grinding device for each welding robot, thereby reducing the number of grinding devices set up.

[0034] The working principle of this embodiment is as follows: the grinding tool 3 and the side convex strip 301 are slidably inserted into the inside of the grinding rotary frame 2, and the bottom of the slide groove connecting the grinding rotary frame 2 and the side convex strip 301 is closed and non-through. During the sliding insertion of the side convex strip 301, the lower end of the side convex strip 301 presses against the inclined surface of the wedge-shaped block 302 to guide the wedge-shaped block 302 to retreat and compress the inner support spring 303. After the groove of the side convex strip 301 moves and aligns with the wedge-shaped block 302, the inner support spring 303 supports the wedge-shaped block 302 and the groove of the side convex strip 301 to fix the position of the grinding tool 3. The personnel can only separate the wedge-shaped block 302 and the side convex strip 301 with a force greater than the inner support spring 303, and the driving motor 102 engages to drive the middle drive The moving gear 101 rotates, the middle driving gear 101 meshes with the middle ring gear 201 to rotate, the middle ring gear 201 and the grinding rack 2 rotate synchronously in the circumferential direction, the grinding tool 3 and the grinding rack 2 rotate synchronously in the circumferential direction, the blade inside the grinding tool 3 performs grinding of the electrode cap, and the four grinding racks 2 arranged in the semicircular ring array perform grinding operations on four electrode caps at the same time. The number of grinding racks 2 can be adjusted according to the model to improve the grinding efficiency of the electrode cap. The four grinding racks 2 can also be used to install four different types of grinding tools 3 to meet the grinding of four different types of electrode caps, eliminating the need to replace the grinding tools 3 back and forth when grinding different types of electrode caps, and reducing the debugging preparation time for grinding different types of spot welding machine electrode caps;

[0035] During the grinding process, the electrode cap needs to press down the grinding rack 2. The grinding rack 2 and the outer convex plate 202 move downward synchronously and compress the lower coil spring 203. The downward movement range of the grinding rack 2 does not exceed the height of the middle ring gear 201. When the grinding rack 2 moves down to the lowest point, the middle ring gear 201 still keeps meshing with the middle driving gear 101. The grinding tool 3 rotates to grind the electrode cap. After the grinding is completed, the electrode cap moves up and separates from the grinding rack 2. The lower coil spring 203 supports the outer convex plate 202 and the grinding rack 2 to move up. The lower coil spring 203 also supports the outer convex plate 202 and the grinding rack 2. The rotating frame 2 performs unnecessary rebound vibration, and the grinding rotating frame 2 and the grinding tool 3 vibrate synchronously. The grinding tool 3 shakes off the metal scraps generated by grinding, thereby reducing the residual metal scraps and reducing the interference of the residual scraps on the grinding of the next electrode cap, thereby avoiding the metal scraps being mixed between the grinding knife and the electrode cap. The obstruction of the metal scraps causes the grinding knife to be unable to directly grind the electrode cap, resulting in uneven grinding. The need to clean up the metal scraps after each grinding is eliminated, thereby reducing the cleaning time during each grinding. The scraps shaken off by the grinding tool 3 fall into the lower scrap collection box 103 for unified treatment.
