Through the setting of the grinding component 7, the two grinding discs 703 can grind the two sides of the busbar fixing hardware at the same time, thereby improving the grinding efficiency of the drilling position of the busbar fixing hardware. An arc-shaped protrusion 101 is fixedly installed on one side of the top of the workbench 1, and the top of the arc-shaped protrusion 101 is placed on the bottom of the adjacent positioning component 4.

[0020] See also Figure 2-3In the embodiment of the utility model: the positioning assembly 4 includes: a mounting cylinder 401, the mounting cylinder 401 is fixedly mounted on one side of the top of the rotating disk 3, a movable rod 402 is movably mounted inside the mounting cylinder 401, and the bottom of the movable rod 402 movably penetrates to the bottom of the rotating disk 3, the top of the arc-shaped protrusion 101 is laid on the bottom of the adjacent movable rod 402, a conical block 403 is fixedly mounted on the top of the movable rod 402, a fixing ring 404 is fixedly connected to the surface of the lower end of the movable rod 402, a first return spring 405 is sleeved on the middle part of the movable rod 402, and one end of the first return spring 405 is fixedly connected to the bottom of the rotating disk 3, and the first return spring The other end of the spring 405 is fixedly connected to the surface of the top of the fixing ring 404, and a T-shaped push rod 406 is symmetrically and horizontally movable through the upper end of the mounting tube 401, and one end of the T-shaped push rod 406 is placed on the surface of the conical block 403, and the other end of the T-shaped push rod 406 extends to the outside of the mounting tube 401, and an arc-shaped tightening clamp 407 is fixedly connected to the other end of the T-shaped push rod 406. A second return spring 408 is mounted on the surface of one end of the T-shaped push rod 406, and one end of the second return spring 408 is fixedly connected to the inner wall of the mounting tube 401, and the other end of the second return spring 408 is fixedly connected to the surface of one end of the T-shaped push rod 406. When the busbar fixing hardware sleeve is placed on the surface of the installation cylinder 401, the output end of the stepper motor 2 drives the rotating disk 3 to rotate 90 degrees each time. When the busbar fixing hardware placed on the surface of the installation cylinder 401 rotates close to the position of the arc-shaped protrusion 101, the bottom of the movable rod 402 is squeezed by the arc surface of the arc-shaped protrusion 101 and moves upward, so that the top conical block 403 pushes one end of the two symmetrical T-shaped push rods 406 to move in the opposite direction, so that the arc-shaped tightening clamp 407 tightens and fixes the inner wall of the hardware, completing the hardware. The tool is clamped and fixed, and then the grinding component 7 grinds both sides of the drilling position on the upper end of the hardware.

When the rotating disk 3 drives the movable rod 402 to rotate 90 degrees, the bottom of the movable rod 402 near the arc protrusion 101 is squeezed by the arc surface of the arc protrusion 101 and moves upward, so that the conical block 403 at the top pushes one end of the two symmetrical T-shaped push rods 406 to move in the opposite direction, so that the arc-shaped clamping plate 407 tightens and fixes the inner wall of the hardware. Since the bottom of the movable rod 402 is arc-shaped, the contact area between the bottom of the movable rod 402 and the surface of the arc protrusion 101 is reduced, the friction between the two is reduced, and the interference is reduced.

[0022] See also Figure 2-3 In the embodiment of the utility model, one end of the T-shaped push rod 406 is set as an inclined surface, and the inclined surface of one end of the T-shaped push rod 406 matches the conical surface of the conical block 403.

[0023] See also Figure 2-3 In the embodiment of the utility model, grooves are symmetrically provided on both sides of the upper end of the installation tube 401, and one side of the arc-shaped clamping plate 407 is placed inside the groove of the inner wall of the installation tube 401. When one end of the T-shaped push rod 406 is not squeezed by the conical block 403, the second reset spring 408 drives the T-shaped push rod 406 to reset, so that the other end of the T-shaped push rod 406 drives the arc-shaped clamping plate 407 to move to the groove position on the surface of the workbench 1, so that the arc-shaped clamping plate 407 moves to the inside of the groove, thereby not affecting the placement of the busbar fixing hardware.

[0024] See also Figure 1-2In the embodiment of the utility model: the grinding assembly 7 includes: a slide plate 701 and an electric push rod 704, two slide plates 701 are provided, the upper ends of the two slide plates 701 are slidably installed in the adjacent slide grooves 601, a driving motor 702 is fixedly installed on one side of the lower end of the slide plate 701, and a grinding disc 703 is fixedly installed on the output end of the driving motor 702, the electric push rod 704 is fixedly installed in the middle position of the top of the connecting plate 6, a mounting plate 705 is fixedly installed on the output end of the electric push rod 704, and a hinged rod 706 is symmetrically hingedly installed on the bottom of the mounting plate 705, and one end of the hinged rod 706 is hingedly installed on the top of the adjacent slide plate 701. After the busbar fixing hardware is fixed, the electric push rod 704 and the drive motor 702 are started, and the output end of the electric push rod 704 pushes the mounting plate 705 to move upward. At this time, the hinged rod 706 symmetrically hinged at the bottom of the mounting plate 705 is deflected, and one end of the two symmetrical hinged rods 706 drives the corresponding slide plate 701 to move closer to the middle of the electric push rod 704. At this time, the output end of the drive motor 702 drives the grinding disc 703 to rotate, and the two grinding discs 703 grind the two sides of the busbar fixing hardware at the same time, thereby improving the grinding efficiency of the drilling position of the busbar fixing hardware.

[0025] Working principle: Turn on the power, put the busbar fixing hardware sleeve on the surface of the installation tube 401, and drive the rotating disk 3 to rotate 90 degrees each time through the output end of the stepper motor 2. When the busbar fixing hardware placed on the surface of the rotating disk 3 rotates close to the position of the arc-shaped protrusion 101, the bottom of the movable rod 402 is squeezed by the arc surface of the arc-shaped protrusion 101 and moves upward, so that the top conical block 403 pushes one end of the two symmetrical T-shaped push rods 406 to move in the opposite direction, so that the arc-shaped tightening clamp 407 tightens and fixes the inner wall of the hardware, completing the clamping and fixing of the hardware, and then start the electric push rod 704 and the drive motor 702, and the output end of the electric push rod 704 pushes the installation disk 705 to move upward. At this time, the hinged rod 706 symmetrically hinged at the bottom of the mounting plate 705 deflects, and one end of the two symmetrical hinged rods 706 drives the corresponding slide plate 701 to move closer to the middle of the electric push rod 704. At this time, the output end of the driving motor 702 drives the grinding disc 703 to rotate, and the two grinding discs 703 grind the two sides of the busbar fixing hardware at the same time. After the grinding is completed, after the stepping motor 2 drives the rotating disc 3 to rotate again, the arc-shaped protrusion 101 releases the squeeze on the bottom of the movable rod 402. At this time, the movable rod 402 is elastically reset by the first reset spring 405, so that the conical block 403 releases the squeeze on one end of the T-type push rod 406, automatically releasing the tightening clamping of the busbar fixing hardware, which is convenient for removing the grinding hardware.
