[0024] Pressing plate 5 is slidably connected with workbench 1 through connecting piece to slide up and down. The connecting piece includes two vertical L-shaped plates, the two L-shaped plates are symmetrically arranged, and multiple fixed rollers 2 are located between the two L-shaped plates. The two L-shaped plates penetrate through workbench 1, and the two L-shaped plates are slidably connected with workbench 1. Pressing plate 5 is located at the top of the two L-shaped plates and is fixedly connected with the two L-shaped plates. The bottom end of the two L-shaped plates is vertically provided with spring 13 between the bottom of workbench 1. The top end of each spring 13 is fixedly connected with the bottom of workbench 1, and the bottom end of each spring 13 is fixedly connected with the bottom end of the L-shaped plate.

[0025] Sliding seat 12 is installed on workbench 1 and slides along horizontal direction, and sliding seat 12 slides along horizontal direction close to or away from pressing plate 5. Electric push rod 7 is fixedly installed on the bottom of workbench 1, and the telescopic shaft of electric push rod 7 is fixedly connected with sliding seat 12. The bottom of sliding seat 12 penetrates through workbench 1, and the notching groove for sliding seat 12 is formed in workbench 1.

[0026] The top of the sliding seat 12 is fixedly provided with a push block 6, which is located between the pressing plate 5 and the sliding seat 12. The push block 6 is provided with a second transmission inclined surface 9 close to the end of the pressing plate 5, and the pressing plate 5 is provided with a first transmission inclined surface 8 close to the end of the sliding seat 12. The top of the first transmission inclined surface 8 is inclined away from the sliding seat 12, and the bottom of the second transmission inclined surface 9 is inclined close to the sliding seat 12. The second transmission inclined surface 9 is in sliding abutment and transmission cooperation with the first transmission inclined surface 8.

[0027] The sliding seat 12 is rotatably provided with grinding teeth 10, which are inserted into the tubular parts 3 in the horizontal direction. The grinding teeth 10 are used to grind the inner wall of the tubular parts 3. The number of the grinding teeth 10 is the same as that of the tubular parts 3, and the grinding teeth 10 correspond to the tubular parts 3 one by one.

[0028] The sliding seat 12 is fixedly provided with a motor 11, and the output shaft of the motor 11 is fixedly connected with the grinding teeth 10 to drive the grinding teeth 10 to rotate. The number of the motor 11 is the same as that of the grinding teeth 10, and the motor 11 corresponds to the grinding teeth 10 one by one.

[0029] Working principle: when the inner wall of the tubular parts 3 is ground, the tubular parts 3 are placed between two adjacent fixed rollers 2. Then the electric push rod 7 is started, and the telescopic shaft of the electric push rod 7 is retracted to drive the sliding seat 12 to slide close to the pressing plate 5.

[0030] At this time, the sliding seat 12 drives the push block 6 to move close to the pressing plate 5, and also drives all the grinding teeth 10 to move close to the corresponding tubular parts 3.

[0031] When the second transmission inclined surface 9 on the push block 6 contacts the first transmission inclined surface 8 on the pressing plate 5, the second transmission inclined surface 9 and the first transmission inclined surface 8 slide relative to each other. At this time, the push block 6 pushes the pressing plate 5 to move downward, and the pressing plate 5 drives the arc-shaped friction plate 4 to be buckled to the tubular parts 3. With the continuous movement of the push block 6, the second transmission inclined surface 9 and the first transmission inclined surface 8 are separated. The push block 6 is pressed on the pressing plate 5, the pressing plate 5 presses the arc-shaped friction plate 4 on the tubular parts 3, and the tubular parts 3 abut against the fixed rollers 2. At this time, the bottom of the push block 6 and the top of the pressing plate 5 slide against each other.

[0032] When the pressing plate 5 moves downward, the two L-shaped plates are pushed to slide downward, and the two L-shaped plates stretch the connected springs 13.

[0033] In this process, the grinding teeth 10 are inserted into the corresponding tubular parts 3. When the second transmission inclined surface 9 of the push block 6 moves over the pressing plate 5, the grinding teeth 10 penetrate the corresponding tubular parts 3.

[0034] After that, the electric push rod 7 is turned off, and the motor 11 is started. The output shaft of the motor 11 drives the grinding teeth 10 to grind the inner wall of the tubular parts 3.

[0035] After the polishing is finished, the motor 11 is turned off, and the electric push rod 7 is started again. The telescopic shaft of the electric push rod 7 is extended and pushes the sliding seat 12 away from the pressing plate 5. At this time, the sliding seat 12 slides out the polishing teeth 10 from the tubular part 3, and the push block 6 is separated from the pressing plate 5.

[0036] When the push block 6 is separated from the pressing plate 5, the two L-shaped plates slide up and push the pressing plate 5 to move up under the elastic force of the spring 13. The pressing plate 5 drives the arc-shaped friction plate 4 to move up and separate from the corresponding tubular part 3.

[0037] Then the tubular part 3 that is polished is taken off the workbench 1.

[0038] Finally, it should be noted that the above only for the preferred embodiments of the present application and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included within the scope of the present application.
