A fixed base 2 is provided on the worktable 1, and an auxiliary mechanism 6 is provided on the fixed base 2. Multiple sets of auxiliary mechanisms 6 can be arranged longitudinally on the fixed base 2. The auxiliary mechanisms 6 are used to limit the movement of the electrode cap 3 and to rotate the electrode cap 3. The auxiliary mechanism 6 includes a rotating rod 61 rotatably engaged with the fixed base 2. One end of the rotating rod 61 is connected to a support block 62. Both ends of the support block 62 are connected to connecting rods 63. The free ends of the connecting rods 63 are hinged to abutment blocks 64. Two sets of support blocks 62 are provided. The second set of support blocks 62 is slidably engaged with a sliding groove 66. A threaded passage for pushing the second set of support blocks 62 is threaded through the second set of support blocks 62. The second lead screw 65 slides on the slide groove 66. The length of the rotating rod 61 is greater than the length of the electrode cap 3. The rotating rod 61 is provided with a through hole. The support block 62 connected to one end of the rotating rod 61 is the first group of support blocks 62. The support block 62 is used to support the rotation of the connecting rod 63. The connecting rod 63 is provided with four groups symmetrically distributed on two groups of abutment blocks 64. The rotation of the connecting rod 63 is used to support the two groups of abutment blocks 64 to move towards or away from each other. The outer wall of the abutment block 64 is provided with an anti-slip layer. The slide groove 66 is opened on the rotating rod 61. The slide groove 66 is a through groove. The slide groove 66 connects to the through hole of the rotating rod 61. The second lead screw 65 rotates through the through hole of the rotating rod 61. One end of the second lead screw 65 is rotatably connected to the side wall of the through groove 66.

[0022] The electrode cap 3 is placed on one end of the first group of the rotating rod 61 connected to the support block 62. The rotating rod 61 is manually restricted, and then the second lead screw 65 is rotated. The second lead screw 65 rotates on the rotating rod 61 and is connected to the second thread of the support block 62, pushing the second group of the support block 62 to move towards the first group of the support block 62. The second group of the support block 62 pushes the connecting rod 63 to move. The moving connecting rod 63 pushes the abutment block 64 to move and press against the inner wall of the electrode cap 3. The first group of the support block 62 and the connecting rod 63 cooperate with the second group of the support block 62 to drive the two groups of abutment blocks 64 to move towards or away from each other, so that electrode caps 3 of various sizes can be fixed, enhancing the adaptability of the equipment.

[0023] A grinding blade 4 is provided on one side of the electrode cap 3. The bottom of the grinding blade 4 is connected to a moving mechanism 5. Multiple sets of moving mechanisms 5 can be arranged longitudinally on the worktable 1. The moving mechanism 5 is used to move the grinding blade 4 laterally to grind the electrode cap 3. The moving mechanism 5 includes a slide plate 51 at the bottom of the grinding blade 4 (the grinding blade 4 can be mounted on the side wall of the slide plate 51 by a mounting bracket at the bottom). A lead screw 52 for pushing the slide plate 51 to move is threaded through the slide plate 51. The bottom end of the slide plate 51 is slidably engaged with the worktable 1. One end of the lead screw 52 is rotatably connected to the side wall of the protrusion of the worktable 1.

[0024] The grinding blade 4 corresponding to the electrode cap 3 is installed on the slide plate 51. The lead screw 52 is rotated, which is threaded to the slide plate 51, pushing the slide plate 51 to move towards the electrode cap 3. This causes the grinding blade 4 to move and contact the electrode cap 3. The rotating rod 61 is manually driven to rotate, and the electrode cap 3 is rotated through the support block 62, connecting rod 63, and abutment block 64. The electrode cap 3 rotates and contacts the grinding blade 4 for grinding, which allows the grinding blade 4 to move laterally for grinding work, reducing the overall height of the equipment.

[0025] Working principle: In this invention, the electrode cap 3 is fitted onto one end of the first group of the rotating rod 61 connected to the support block 62. The rotating rod 61 is manually restricted, and then the second lead screw 65 is rotated. The second lead screw 65 rotates on the rotating rod 61 and is connected to the second thread of the support block 62, pushing the second group of the support block 62 to move towards the first group of the support block 62. The second group of the support block 62 pushes the connecting rod 63 to move. The movement of the connecting rod 63 pushes the abutment block 64 to move and press against the inner wall of the electrode cap 3. The first group of the support block 62 and the connecting rod 63 cooperate with the second group of the support block 62 to drive the two groups of abutment blocks 64 to move towards or away from each other. The device can be moved to fix electrode caps 3 of various sizes, which enhances the adaptability of the equipment. The grinding blade 4 corresponding to the electrode cap 3 is installed on the slide plate 51. The lead screw 52 is screwed to the slide plate 51, which pushes the slide plate 51 to move towards the electrode cap 3. The grinding blade 4 then moves and contacts the electrode cap 3. The rotating rod 61 is manually driven to rotate. The electrode cap 3 rotates through the support block 62, the connecting rod 63 and the abutment block 64. The electrode cap 3 rotates and contacts the grinding blade 4 for grinding. This allows the grinding blade 4 to move laterally for grinding, which reduces the overall height of the equipment.

[0026] Grinding tools and lead screws are existing technologies and will not be elaborated upon here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
