[0016] Beneficial effects of the utility model:

[0017] 1. The utility model uses a swivel to fix and clamp the sheet metal box workpiece that needs to be polished through a clamping mechanism. The grinder can move longitudinally by relying on the lifting slide bar, move horizontally forward and backward along the support guide rail by relying on the support guide cylinder, and slide left and right along the horizontal slide groove by relying on the support guide rail, so that the grinder can enter the box workpiece to contact the lower end surface for polishing.

[0026] A plurality of clamping mechanisms are arranged on the swivel 3, and the clamping mechanisms include electric telescopic rods 4. A plurality of electric telescopic rods 4 are arranged and are equidistantly distributed on the swivel 3 in the circumferential direction. The telescopic end of each electric telescopic rod 4 points to the center position of the swivel 3. A clamping block 5 is connected to the telescopic end of each electric telescopic rod 4. A non-slip rubber pad is arranged on the clamping end surface of the clamping block 5 to increase the anti-slip property.

A cross arm 21 parallel to the support guide rail 9 is horizontally fixedly connected to one side of the top end of the lifting slide bar 11. The cross arm 21 is equal to the support guide rail 9 in length. A grinder 12 is connected to the end of the cross arm 21. The grinding head of the grinder 12 is in the shape of a grinding disc. When it is necessary to grind the clamped box workpiece 6, the lifting slide bar 11 is first made to slide up and down relative to the support guide cylinder 10, and the height position of the grinder 12 is adjusted to align it with the inside of the box workpiece 6 The inner space is then slid along the support guide rail 9 to support the guide cylinder 10, so that the lifting slide bar 11 drives the grinder 12 to enter the box workpiece 6 through the cross arm 21. When a certain inner end face of the box workpiece 6 needs to be polished, the electric slider 7 drives the rotating ring 3 to rotate, and the rotating ring 3 drives the box workpiece 6 to rotate through the clamping mechanism, so that the corresponding inner end face is deflected to the bottom of the grinder 12, and then the lifting slide bar 11 drives the grinder 12 to descend and contact the inner end face of the box workpiece 6 for polishing, and during the polishing process, the support guide rail 9 can be relied on to slide along the horizontal slide groove 8, so that the grinder 12 can move left and right, and the grinder 12 can also rely on the support guide cylinder 10 to move forward and backward along the support guide rail 9, which is convenient for polishing;

[0028] A sleeve 16 is horizontally arranged on one side of the support guide cylinder 10 near the top, and the sleeve 16 is connected to the internal space of the support guide cylinder 10. An iron top block 19 is slidably arranged inside the sleeve 16, and the iron top block 19 fits with the lifting slide bar 11.

A compressible limit spring 18 is connected between the inner wall of the sleeve 16 away from the lifting slide bar 11 and the iron top block 19. When the limit spring 18 is in the original state, the iron top block 19 The sleeve 16 abuts against the lifting slide bar 11, so that its position relative to the supporting guide cylinder 10 is fixed; an electromagnet 17 aligned with the iron top block 19 is also fixedly connected to the inner wall of the sleeve 16 away from the lifting slide bar 11; a power switch group electrically connected to the electromagnet 17 is provided on the grinder 12, and the power switch group includes a handle 13 and a power button switch 14, the handle 13 is fixedly connected to the top of the grinder 12, the power button switch 14 is installed on the side wall of the handle 13, and the power button switch 14 is electrically connected to the electromagnet 17, and the power button switch 14 is an elastic switch, which connects the circuit when pressed and resets and disconnects the circuit after releasing;

[0029] When the operator needs to lift the grinder 12, he grabs the handle 13 with his hand.

When it is necessary to grind a certain inner end face of the box workpiece 6, the electric slider 7 drives the rotating ring 3 to rotate, and the rotating ring 3 drives the box workpiece 6 to rotate through the clamping mechanism, so that the corresponding inner end face is deflected to the bottom of the grinder 12, and then the lifting slide bar 11 drives the grinder 12 to descend and contact the inner end face of the box workpiece 6 for grinding, and during the grinding process, the supporting guide rail 9 can be relied on to slide along the horizontal slide groove 8, so that the grinder 12 can move left and right, and the grinder 12 can also rely on the supporting guide cylinder 10 to move forward and backward along the supporting guide rail 9 for easy grinding;

[0032] When the operator releases the handle 13, the power-on button switch 14 is reset, the electromagnet 17 is powered off and loses its magnetic force, and the iron top block 19 is reset by the rebound force of the limit spring 18, and the lifting slide bar 11 is fixed again to support it relative to the supporting guide cylinder 10, so that the grinder 12 can be prevented from falling under the action of gravity, and it can be adjusted to the corresponding height and automatically fixed after being released.
