[0027] The replaceable component 3 includes a moving block 301, a mounting groove 302 is provided on one side of the moving block 301, and a mounting block 303 is connected to the inner wall of the mounting groove 302 by snapping, a clamping plate 304 is fixedly connected to one side of the mounting block 303, a positioning groove 305 is provided on one side of the mounting block 303, and a positioning rod 306 is connected to the inner wall of the positioning groove 305 by snapping, a lifting plate 307 is fixedly connected to one end of the positioning rod 306, and a screw 308 is threadedly connected to the inner wall of the lifting plate 307;

[0028] The rotating assembly 8 includes a motor 801, the output end of the motor 801 is detachably connected to a rotating rod 802 via a coupling, and the outer surface of the rotating rod 802 is fixedly connected to a first gear 803, the outer wall of the first gear 803 is meshed with a second gear 804, and the inner wall of the second gear 804 is fixedly connected to a connecting column 805, the outer surface of the connecting column 805 is fixedly connected to a rotating block 806, and a sliding groove 807 is provided on the inner wall of the base 1.

[0029] Through the above technical solution, the mounting block 303 on one side of the splint 304 can be disassembled and installed with the movable block 301. The mounting block 303 only needs to be inserted into the mounting groove 302, and then the screw 308 can be turned by hand to make the positioning rod 306 extend into the positioning groove 305 to fix the mounting block 303, thereby achieving the effect of quickly installing the splint 304. Splints 304 of different shapes can be replaced for installation according to accessories of different shapes, so that accessories of different shapes can be effectively clamped and fixed, thereby improving the clamping effect of the accessories and improving practicality.

[0030] Specifically, a driving mechanism 4 is disposed inside the workbench 2 , a support frame 5 is fixedly connected to the top of the base 1 , a lifting mechanism 6 is installed at the bottom of the support frame 5 , and a processing mechanism 7 is disposed at the bottom of the lifting mechanism 6 .

[0031] Through the above technical solution, it is convenient to start the driving mechanism 4 to move the two moving blocks 301 inward, and then clamp and fix the accessories through the clamping plate 304, and a cylinder is provided on the lifting mechanism 6 at the bottom of the support frame 5. Starting the cylinder can make the processing mechanism 7 move downward to process the fixed accessories.

[0032] Specifically, the moving block 301 forms a snap-fit ​​structure with the mounting block 303 via the mounting groove 302 , and the shape and size of the mounting groove 302 match the shape and size of the mounting block 303 .

[0033] Through the above technical solution, the mounting block 303 on one side of the splint 304 can be inserted into the mounting groove 302 for installation with the moving block 301, thereby achieving the effect of preliminary connection between the splint 304 and the moving block 301, and also facilitating the replacement of the splint 304.

[0034] Specifically, the mounting block 303 forms a snap-fit ​​structure with the positioning rod 306 through the positioning groove 305 , and the shape and size of the positioning groove 305 match the shape and size of the positioning rod 306 .

[0035] Through the above technical solution, after the mounting block 303 is inserted into the mounting groove 302, the positioning rod 306 can be inserted into the positioning groove 305 to fix the mounting block 303 up and down, so that the mounting block 303 cannot be pulled out of the mounting groove 302, thereby achieving the effect of fixing the splint 304.

[0036] Specifically, the moving block 301 forms a lifting structure with the lifting plate 307 through the screw rod 308 , and the threads on both sides of the screw rod 308 rotate in opposite directions, and the number of the lifting plates 307 is two.

[0037] Through the above technical solution, manually rotating the screw 308 can drive the lifting plate 307 to move up and down, because the threads on both sides of the screw 308 rotate in opposite directions, and the two lifting plates 307 are symmetrically arranged on both sides of the screw 308, so that the rotation of the screw 308 can drive the lifting plates 307 to move relatively, and then the lifting plates 307 drive the positioning rod 306 to move, thereby achieving the effect of controlling the lifting and lowering of the positioning rod 306.

[0038] Specifically, the motor 801 forms a rotating structure with the first gear 803 through the rotating rod 802 , and the shape and size of the outer wall of the first gear 803 match the shape and size of the outer wall of the second gear 804 .

[0039] The above technical solution facilitates the starter motor 801 to drive the rotating rod 802 to rotate and the first gear 803 to rotate at the same time. Since the first gear 803 and the second gear 804 are meshed with each other, the second gear 804 is rotated.

[0040] Specifically, the second gear 804 forms a rotating structure with the workbench 2 via the connecting column 805 , and the connecting column 805 is arranged between the second gear 804 and the workbench 2 . The shape and size of the rotating block 806 match the shape and size of the sliding groove 807 .

[0041] Through the above technical solution, the second gear 804 can rotate while driving the connecting column 805 to rotate, and the connecting column 805 can drive the workbench 2 to rotate. During the rotation of the connecting column 805, the rotating block 806 can rotate synchronously in the slide groove 807, thereby improving stability, and then causing the accessories on the workbench 2 to rotate, thereby achieving the effect of rotating the accessories.

[0042] Working principle: When using the positioning tooling for processing mechanical parts, first, when replacing the splint 304, you only need to manually rotate the screw 308, and the screw 308 drives the two lifting plates 307 to rise and fall relatively, so that the lifting plate 307 drives the positioning rod 306 to disengage from the positioning groove 305, release the limit fixation of the mounting block 303, and then pull the mounting block 303 on one side of the splint 304 out of the mounting groove 302 to complete the disassembly, and then extend the mounting block 303 on one side of the adapted splint 304 into the mounting groove 302 for connection, and then rotate the screw 308 in the opposite direction, so that the positioning rod 306 on one side of the lifting plate 307 is released. 06 extends into the positioning groove 305 to complete the limiting fixation of the mounting block 303, and then completes the quick installation of the splint 304. When rotating the accessory, first start the motor 801. The motor 801 drives the rotating rod 802 to rotate and drives the first gear 803 to rotate at the same time. The first gear 803 drives the second gear 804 to rotate due to the meshing action. The second gear 804 drives the workbench 2 on the top of the connecting column 805 to rotate, so that the accessory on the workbench 2 rotates. This completes all the work.
