[0039] The first screw 301 is threadedly connected to the rectangular frame 2, the outer surface of the first screw 301 is rotatably connected to the slide frame 302, the interior of the slide frame 302 is clamped with a first ring 303, the interior of the first ring 303 is rotatably connected to the second screw 304, the interior of the first ring 303 is fixedly connected to an electric grinder 305, the interior of the slide frame 302 is clamped with a first slide 306, and the first screw 301 is used to vertically adjust the electric grinder 305.
[0040] The grinding mechanism 3 also includes a threaded locking ring 307, which is clamped with the first slide groove 306. The internal thread of the threaded locking ring 307 is connected with a locking plate 308. The inner wall of the threaded locking ring 307 is rotatably connected with a limiting sleeve shaft 309. The outer surface of the limiting sleeve shaft 309 is threadedly connected with a threaded cylinder 310. The locking plate 308 is used to horizontally fix the electric grinder 305.

When grinding the parts, due to the limited width of the slide frame 302 itself and the limited adjustment of the slide frame 302, the deep hole directly below the slide frame 302 cannot be accurately positioned and ground. At this time, by adjusting the rotation speed of the two symmetrically arranged third screws 401, they are eccentrically clamped, so that the deep hole directly below the slide frame 302 can be ground.
[0042] The limiting mechanism 4 includes a third screw 401, which is threadedly connected to the rectangular frame 2, the outer surface of the third screw 401 is rotatably connected to the first arc column 402, the outer surface of the first arc column 402 is fixedly connected to the first limiting shaft 403, the outer surface of the first limiting shaft 403 is rotatably connected to the first rotating frame 404, the outer surface of the first rotating frame 404 is clamped with a rough sleeve 405, the outer surface of the first rotating frame 404 is rotatably connected to the first rotating plate 406, the internal thread of the first rotating plate 406 is connected to the fourth screw 407, the upper surface of the fourth screw 407 is fixedly connected to the top plate 409, the lower surface of the top plate 409 is fixedly connected to the bellows 408, the outer surface of the top plate 409 is clamped with a slide column 410, and the slide column 410 is used to support mechanical parts.
[0043] The upper surface of the first rotating frame 404 contacts the lower surface of the first arc-shaped column 402, the upper surface of the first rotating frame 404 contacts the lower surface of the rectangular frame 2, the lower surface of the roughened sleeve 405 contacts the upper surface of the first rotating plate 406, the lower surface of the bellows 408 is fixedly connected to the upper surface of the first rotating plate 406, the first arc-shaped column 402 is used to horizontally limit the mechanical parts, when it is necessary to grind the deep holes on the lower surface of the parts, the distance between the lower surface of the parts and the base plate 1 can be adjusted by the fourth screw 407, so that the grinding mechanism 3 located on the lower surface can extend into the deep hole for grinding, and the rotation limit of the parts is ensured by the limit of the roughened sleeve 405 located on the upper surface of the rectangular frame 2.
[0044] The working principle of this embodiment is as follows: when using this deep hole inner wall grinding equipment for mechanical parts, the mechanical parts are placed on the upper surface of the slide groove column 410, at this time, the third screw 401 is started, pushing the first arc column 402 to move, and cooperating with the symmetrically arranged first arc column 402, contacting the outer surface of the mechanical parts from both sides, at this time, the first rotating frame 404 is rotated, so that the first rotating frame 404 rotates around the first limiting rotating shaft 403, driving the rough surface sleeve 405 to contact the outer surface of the mechanical parts, at this time, the third screw 401 continues to push, so that the first arc column 402 is clamped with the side of the part, and at the same time, the fourth screw 407 rotates, and pushes the slide groove column 410 to be in close contact with the lower surface of the part through the top plate 409, and with the assistance of the clamping of the first arc column 402, the position of the part is limited, and the rough surface sleeve 405 is in close contact with the side of the part to limit the rotation of the part, and at the same time, when the first arc column 402 is clamped, the whole mechanism is driven The body moves inward, and the top plate 409 slides inside the slide column 410 to ensure that the overall inward movement of the mechanism is not affected. After the parts are clamped, the slide frame 302 is rotated around the axis of the first screw 301, and the threaded locking collar 307 slides inside the first slide 306. When the electric grinder 305 coincides with the axis of the deep hole to be grinded, the rotation stops. At this time, the locking piece 308 is rotated to make its outer surface closely contact with the outer surface of the slide frame 302, so that the slide frame 302 and the threaded locking sleeve The ring 307 is locked and fixed, so that the horizontal position of the electric grinder 305 is fixed. At this time, the first screw 301 rotates, and the electric grinder 305 grinds the deep hole through the slide frame 302. After the grinding is completed, it is flipped out, and the position of the electric grinder 305 is adjusted by the second screw 304, so that it can grind the deep hole located on the axis of the second screw 304. After completing the deep hole grinding in this fixed position, the above positioning process is repeated to grind the deep holes on the parts.
[0045] Example 2: Please refer to Figure 7-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary mechanism 5 includes a second arc column 501, the second arc column 501 is clamped with the first rotating frame 404, the interior of the second arc column 501 is rotatably connected to the first rotating shaft 502, the outer surface of the first rotating shaft 502 is rotatably connected to the second limiting rotating shaft 504, the outer surface of the second limiting rotating shaft 504 is rotatably connected to the rotating shaft frame 505, the outer surface of the rotating shaft frame 505 is rotatably connected to the suction cup 506 and the electromagnet 507, the suction cup 506 and the electromagnet 507 are used to horizontally limit the rough surface sleeve 405.

When double-sided deep hole grinding of parts is performed, due to the adjustment of the distance between the lower surface of the part and the base plate 1, the limiting area of the roughened sleeve 405 on the lower surface of the rectangular frame 2 is reduced, and the roughened sleeve 405 on the upper surface of the rectangular frame 2 is subjected to increased force, and it needs to be auxiliary limited to ensure its working performance.
[0047] The working principle of this embodiment is as follows: when using this deep hole inner wall grinding equipment for mechanical parts, when clamping the parts, the first rotating frame 404 is rotated to make the rough sleeve 405 contact with the outer surface of the part, and at this time, the second rotating plate 503 is rotated around the first rotating shaft 502 to make the direction of the rotating shaft frame 505 perpendicular to the contact surface of the part, and at this time, the auxiliary mechanism 5 slides on the outer surface of the first rotating shaft 502, so that the suction cup 506 can suck and fix the surface of the part. If there is no position for the suction cup 506 to suck and fix on the surface of the part, the rotating shaft frame 505 can be rotated to make the electromagnet 507 and the outer surface of the part magnetically fixed. When the suction cup 506 is sucked and fixed and the electromagnet 507 is magnetically fixed, the auxiliary mechanism 5 is tightened as a whole, so that the rough sleeve 405 located on the upper surface of the rectangular frame 2 can be tightly attached to the surface of the part, and it can continue to be tightly attached through the suction cup 506 and the electromagnet 507.
