Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a boring machine for processing a vacuum pump pump body, including a boring machine main body 1 and a workbench 3. A moving mechanism 4 is arranged on the top of the workbench 3, an adjusting mechanism 5 is arranged on one side of the moving mechanism 4, an adaptive fixing mechanism 6 is arranged on one side of the adjusting mechanism 5, a pump body 7 is attached to the top of the workbench 3, and a plurality of foot pads 2 are connected to the bottom of the workbench 3;

[0029] The adjusting mechanism 5 includes two fixing blocks 504. A moving groove 505 is opened in the fixing block 504. A moving rod 503 is slidably connected to the inner wall of the moving groove 505. Both ends of the moving rod 503 extend outside the moving groove 505. A plurality of second extrusion blocks 509 are connected to the outer wall of the moving rod 503. A plurality of sliding grooves 506 are opened on the outer wall of the fixing block 504. The cross-section of the sliding groove 506 is T-shaped. One side of the sliding groove 506 communicates with one side of the moving groove 505. The outer wall of the second extrusion block 509 is slidably connected to the inner wall of the sliding groove 506. A first extrusion block 508 is slidably connected to the inner wall of the sliding groove 506. One side of the first extrusion block 508 is attached to one side of the second extrusion block 509. A limiting groove is opened on one side of the first extrusion block 508. A limiting block 510 is connected to one side of the second extrusion block 509. The cross-sections of both the limiting block 510 and the limiting groove are T-shaped. The outer wall of the limiting block 510 is slidably connected to the inner wall of the limiting groove. Sliders 507 are connected to both sides of the first extrusion block 508. The outer walls of the sliders 507 are slidably connected to the inner wall of the sliding groove 506. One side of the fixing block 504 is connected to a connecting cover 502. A cylinder 501 is connected to one side of the connecting cover 502. The ejector rod of the cylinder 501 extends into the connecting cover 502 and is connected to one end of the moving rod 503.

[0030] The implementation method is specifically as follows: By setting the adjustment mechanism 5, the movement of the ejector rod of the cylinder 501 drives the movement of the moving rod 503. The movement of the moving rod 503 drives the movement of a plurality of second extrusion blocks 509 in the sliding groove 506. Since one side of the second extrusion block 509 is set as an inclined surface, and the side where the first extrusion block 508 and the second extrusion block 509 are in extrusion is also set as an inclined surface, the second extrusion block 509 can drive the first extrusion block 508 to move in the sliding groove 506. The first extrusion block 508 can drive the rotating block 602 to move through the connecting rod 605 on the mounting seat 601, so that the position of the rotating block 602 can be adjusted, enabling the rotating block 602 to be adjusted to a suitable fixed position according to the inner diameter of the pump body 7. Furthermore, the pump body 7 with different inner diameters can be fixed, improving the applicability of the boring machine and saving the time wasted on replacing the fixture, thereby improving the processing efficiency of the boring machine. By setting the limit block 510 and the limit groove, the first extrusion block 508 will not slide out of the sliding groove 506. By setting the slider 507, the first extrusion block 508 will not tilt when moving in the sliding groove 506.

[0031] The self - adaptive fixing mechanism 6 includes a plurality of mounting seats 601. The bottom of the mounting seat 601 is connected to the top of the first extrusion block 508. Two rotating blocks 602 are attached to the inner wall of the mounting seat 601. A through - groove 603 is formed in the rotating block 602. A plurality of springs 604 are connected to the bottom of the rotating block 602, and the other ends of the springs 604 are connected to the inner wall of the mounting seat 601. Two connecting rods 605 are connected to the inner wall of the mounting seat 601. The outer wall of the connecting rod 605 is rotatably connected to the inner wall of the through - groove 603. The moving mechanism 4 includes a sliding groove 403 and a motor 404. The sliding groove 403 is formed in the top of the workbench 3. One side of the motor 404 is connected to one side of the workbench 3. A bidirectional threaded rod 402 is rotatably connected to the inner wall of the sliding groove 403. The output shaft of the motor 404 extends into the sliding groove 403 and is connected to one end of the bidirectional threaded rod 402. Two threaded blocks 401 are threadedly connected to the outer wall of the bidirectional threaded rod 402. The outer wall of the threaded block 401 is slidably connected to the inner wall of the sliding groove 403. One side of the threaded block 401 is connected to a fixed cover 405, and one side of the fixed cover 405 is connected to one side of the fixed block 504.

[0032] The implementation method is specifically as follows: By setting the adaptive fixing mechanism 6, when one side of the rotating block 602 contacts the inner wall of the pump body 7, the rotating block 602 will be squeezed by the inner wall of the pump body 7. Through the settings of the connecting rod 605 and the through groove 603, the rotating block 602 can rotate when being squeezed, and can drive the spring 604 to generate elastic force. The rotating block 602 can adjust its angle to be suitable for the inner wall of the pump body 7 through rotation, so as to better fit the inner wall of the pump body 7, making the rotating block 602 fit more closely with the inner wall of the pump body 7, thereby improving the fixing stability of the rotating block 602, and avoiding the sliding of the pump body 7 during processing and affecting the processing effect. Through the setting of the spring 604, when the rotating block 602 separates from the inner wall of the pump body 7, the rotating block 602 can return to its original position. By setting the side of the rotating block 602 in contact with the inner wall of the pump body 7 as an arc surface, the rotating block 602 can better fit the inner wall of the pump body 7.

[0033] Working principle: During use, place the pump body 7 on the workbench 3, and then start the motor 404. The output shaft of the motor 404 rotates to drive the bidirectional threaded rod 402 to rotate. The bidirectional threaded rod 402 drives the threaded blocks 401 on both sides to approach each other through two sections of opposite threads arranged on the surface. The threaded block 401 can drive the fixed block 504 to move through the fixed cover 405, so that the fixed block 504 can drive the mounting seat 601 and the rotating block 602 into the pump body 7 through the first extrusion block 508. Then start the cylinder 501. The moving rod 503 and multiple second extrusion blocks 509 move in the sliding groove 506 driven by the moving rod of the cylinder 501. Since one side of the second extrusion block 509 is set as an inclined surface, and the side of the first extrusion block 508 in contact with the second extrusion block 509 is also set as an inclined surface, the second extrusion block 509 can drive the first extrusion block 508 to move in the sliding groove 506. The first extrusion block 508 can drive the rotating block 602 to move through the connecting rod 605 on the mounting seat 601, so as to adjust the position of the rotating block 602, enabling the rotating block 602 to fix pump bodies 7 with different inner diameters. By setting the limit block 510 and the limit groove, the first extrusion block 508 will not slide out of the sliding groove 506. By setting the slider 507, the first extrusion block 508 will not tilt when moving in the sliding groove 506. When one side of the rotating block 602 contacts the inner wall of the pump body 7, the rotating block 602 will be squeezed by the inner wall of the pump body 7. Through the settings of the connecting rod 605 and the through groove 603, the rotating block 602 can rotate when being squeezed, and can drive the spring 604 to generate elastic force. The rotating block 602 can adjust its own angle to be suitable for the inner wall of the pump body 7 through rotation, so as to better fit the inner wall of the pump body 7, making the rotating block 602 fit more closely with the inner wall of the pump body 7, thereby improving the fixing stability of the rotating block 602.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
