By setting the gear 12 and the gear ring 13, the three-jaw chuck 4 can drive the fixed parts to rotate, avoiding the deviation caused by manual rotation, thereby reducing the error caused by the detection of the detection equipment 2.

[0031] A slide plate 5 is slidably connected to the base plate 1, and a truncated cone block 6 is rotatably connected to the outer wall of the slide plate 5. A conical groove 7 is provided inside the truncated cone block 6. A driving mechanism for pushing the slide plate 5 to move horizontally is provided on the base plate 1; by providing a transversely movable truncated cone block 6, the distance between the truncated cone block 6 and the three-jaw chuck 4 can be adjusted, so that shaft parts with longer lengths can be supported. The conical groove 7 is provided, and the inner wall of the conical groove 7 is fitted on the outer wall of the conical end of the part, so that it can play a supporting role, thereby expanding the overall application range of the device.

[0032] The driving mechanism includes a slide 8, a motor 9 and a reciprocating screw 10;

[0033] A slide groove 8 is opened inside the base plate 1, and a motor 9 is installed on the outer wall of the base plate 1. A reciprocating screw 10 is sleeved on the output end of the motor 9. The reciprocating screw 10 is rotatably connected to the inner wall of the slide groove 8. A movable block is threadedly connected to the outer wall of the reciprocating screw 10, and the top of the movable block is connected to the bottom end of the slide plate 5.

[0034] A movable plate 14 is slidably connected to the top of the base plate 1, and two threaded rods 17 are threadedly connected to the inside of the movable plate 14. The ends of the two threaded rods 17 are rotatably connected to connecting rods 18, and the other ends of the two connecting rods 18 are rotatably connected to cleaning brushes 19. By providing a cleaning brush 19 with an adjustable inclination angle, the outer walls of different shaft parts can be cleaned, thereby reducing foreign matter attached to the outer walls of the parts, further reducing the error of subsequent detection equipment 2 in detecting parts, and thereby improving the use effect of the cleaning brush 19.

[0035] The top of the bottom plate 1 is connected to a vertical pole 15 , and the movable plate 14 is slidably connected to the outer wall of the vertical pole 15 . The top of the bottom plate 1 is connected to an electric push rod 16 , and the top of the output rod of the electric push rod 16 is connected to the bottom end of the movable plate 14 .

[0036] The top of the vertical rod 15 is connected with a fixing block.

[0037] The testing device 2 includes a vertical plate, a screw rod, a screw block and a micrometer;

[0038] The top of the bottom plate 1 is connected with a vertical plate, a screw is rotatably connected inside the vertical plate, a screw block is threadedly connected to the outer wall of the screw, and a micrometer for detecting parts is connected to the side wall of the screw block.

[0039] Working principle: insert different shaft parts into the three-jaw chuck 4, clamp and fix the parts by the three-jaw chuck 4, drive the gear 12 to rotate by the motor 11, so that the gear 12 drives the gear ring 13 to rotate, so that the gear ring 13 drives the three-jaw chuck 4 to rotate on the inner wall of the fixed plate 3, thereby driving the parts to rotate, cooperate with the detection equipment 2 to detect the rotating parts, and when the parts rotate one circle, the circular runout data is obtained;

[0040] When the shaft parts are long and the ends of the shaft parts need to be supported, the reciprocating screw 10 is driven to rotate by the motor 9, so that the movable block outside the reciprocating screw 10 moves inside the slide groove 8, thereby driving the slide plate 5 at the top of the movable block to move until the side wall of the truncated cone block 6 abuts against the end of the shaft parts, thereby supporting the parts. The truncated cone block 6 can be driven to rotate on the slide plate 5 by the rotation of the parts. When the truncated cone block 6 supports shaft parts with a certain length and a tapered end, the tapered groove 7 is provided so that the inner wall of the tapered groove 7 fits against the outer wall of the tapered end of the part, thereby playing a supporting role, thereby expanding the overall application range of the device.

[0041] The movable plate 14 is driven to rise and fall by the electric push rod 16, so that the movable plate 14 slides on the outer wall of the vertical rod 15. Under the action of the fixed block at the top of the vertical rod 15, the height of the movable plate 14 can be limited. After the height of the cleaning brush 19 is raised and lowered to the same horizontal position as the part, the driving of the electric push rod 16 can be stopped. By rotating the two threaded rods 17, the threaded rods 17 are moved inside the movable plate 14, thereby driving the cleaning brush 19 to fit the outer wall of the shaft part. The part is driven to rotate by the three-jaw chuck 4, so that the cleaning brush 19 can clean the outer wall of the part, thereby reducing foreign matter attached to the outer wall of the part, and further reducing the error of the subsequent detection equipment 2 in detecting the part. By rotating any threaded rod 17, the connecting rod 18 drives the cleaning brush 19 to tilt, thereby adjusting the inclination angle of the cleaning brush 19, so that the cleaning brush 19 can clean the tapered part of the shaft part with a tapered end, thereby improving the use effect of the cleaning brush 19.
