[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the utility model provides a positioning assembly for honing and polishing the inner hole of a ceramic cylinder liner, comprising a support plate 1 and a pipe fitting 2. The support plate 1 is symmetrically arranged, and support discs 3 are fixedly connected to opposite sides of the support plate 1. Several clamping mechanisms 4 are arranged on both sides of the support disc 3. The pipe fitting 2 passes through the support disc 3, and the clamping mechanism 4 is movably connected to the outer side of the pipe fitting 2. The interior of the support disc 3 is movably connected to an adjusting mechanism 5, and the adjusting mechanism 5 is connected to the clamping mechanism 4. A driving mechanism 6 is arranged on the outer side of the support disc 3, and the driving mechanism 6 is connected to the adjusting mechanism 5.

[0025] like Figure 1 and Figure 4As shown, the clamping mechanism 4 includes a clamping plate 401, a connecting plate 402 and a driving plate 403. One end of the connecting plate 402 is movably connected to the back side of the clamping plate 401 through a rotating shaft, and the other end of the connecting plate 402 is movably connected to the side of the support disk 3 through a rotating shaft. One end of the driving plate 403 is movably connected to the inner side of the connecting plate 402 through a rotating shaft. The clamping plate 401 is arc-shaped, and several friction strips 7 are provided on the front side of the clamping plate 401. The front side of the clamping plate 401 is tightly fitted with the outer side surface of the pipe fitting 2 through the friction strips 7. The friction strips 7 on one side of the support disk 3 are arranged axially along the pipe fitting 2, and the friction strips 7 on the other side of the support disk 3 are arranged circumferentially along the pipe fitting 2.

[0026] Since the surface of the arc block 502 fits with the surface of the protrusion 503, the arc block 502 is squeezed, so that several arc blocks 502 move toward the pipe fitting 2, driving the connecting plate 501 to move synchronously, compressing the return spring 8 to shorten it, and the movement of the connecting plate 501 pulls the movement of the driving plate 403. The driving plate 403 drives the connecting plate 402 to rotate around its rotating axis, so that the splint 401 gradually approaches the surface of the pipe fitting 2. In addition, the friction strips 7 on the front side of the splint 401 on both sides of the support plate 3 are set in different ways. One type of friction strip 7 is set along the axial direction of the pipe fitting 2, and the other type of friction strip 7 is set along the circumferential direction of the pipe fitting 2, thereby reducing the position offset of the pipe fitting 2 in the circumferential and axial directions.

[0027] like Figure 1 、 Figure 3 and Figure 4 As shown, the adjustment mechanism 5 includes a connecting plate 501, an arc block 502, a protrusion 503 and a driving ring 504. The connecting plate 501, the arc block 502 and the protrusion 503 are distributed in a circular array. The connecting plates 501 are fixedly connected to both sides of the arc block 502. The arc block 502 and the connecting plate 501 are movably connected to the inside of the support disk 3. The driving ring 504 is movably connected to the inside of the support disk 3, and the protrusion 503 is fixedly connected to the inner side of the driving ring 504. The surface of the arc block 502 is respectively fitted with the surface of the protrusion 503. The connecting plates 501 are all L-shaped. The inner side of the connecting plates 501 is fixedly connected to a return spring 8. The other end of the return spring 8 is fixedly connected to the inside of the support disk 3. The end of the driving plate 403 away from the connecting plate 402 is movably connected to the end of the connecting plate 501 through a rotating shaft.

[0028] The driving ring 504 drives the protrusion 503 to rotate synchronously. Since the surface of the arc block 502 fits the surface of the protrusion 503, the arc block 502 is squeezed, so that several arc blocks 502 move toward the pipe 2.

[0029] like Figure 1 and Figure 2As shown, the driving mechanism 6 includes a worm 601 and a servo motor 602. A worm gear groove is constructed on the outer side of the driving ring 504. The driving ring 504 engages with the worm 601 through the worm gear groove. The servo motor 602 is fixedly connected to the outer side of the support plate 3, and the output end of the servo motor 602 is fixedly connected to one end of the worm 601. The outer side of the support plate 3 is fixedly connected to a containing cover 9, and the worm 601 is movably connected to the inside of the containing cover 9.

[0030] The servo motor 602 is started to drive the worm 601 to rotate. Since the outer side of the driving ring 504 is configured with a worm gear groove, the driving ring 504 is meshed with the worm 601 to control the driving ring 504 to rotate inside the supporting plate 3.

[0031] Working principle: When in use, first, pass the pipe 2 through the support plate 3, then start the servo motor 602 to drive the worm 601 to rotate the rod. Since the outer side of the driving ring 504 is configured with a worm gear groove, the driving ring 504 is engaged with the worm 601, thereby controlling the driving ring 504 to rotate inside the support plate 3, and the driving ring 504 drives the protrusion 503 to rotate synchronously. Since the surface of the arc block 502 fits the surface of the protrusion 503, the arc block 502 is squeezed, so that several arc blocks 502 are all toward the pipe. 2 moves, driving the connecting plate 501 to move synchronously, compressing the return spring 8 and shortening it. The movement of the connecting plate 501 pulls the movement of the driving plate 403, and the driving plate 403 drives the connecting plate 402 to rotate around its rotating axis, so that the clamping plate 401 gradually approaches the surface of the pipe fitting 2. In addition, the friction strips 7 on the front side of the clamping plates 401 on both sides of the support plate 3 are set in different ways. One type of friction strip 7 is set along the axial direction of the pipe fitting 2, and the other type of friction strip 7 is set along the circumferential direction of the pipe fitting 2, thereby reducing the position offset of the pipe fitting 2 in the circumferential and axial directions.
