The electric push rod 7 is first controlled to contract, and then the spring 8 is compressed to generate elastic force, and the part to be detected is fixed through the movable plate 12 and the fixed plate 13. Then the electric slider 5 drives the shell 4 to move to one end of the part to be detected, and then the electric push rod 7 is closed. Under the action of the elastic force of the spring 8, the matching wheel 10 is abutted against the part to be detected, the first displacement sensor 9 is zeroed, and the electric slider 5 drives the shell 4 to move, thereby making the matching wheel 10 move on the surface of the part to be detected, and the height change of the matching wheel 10 is recorded by the displacement sensor 9, so as to measure the deformation degree of the part to be detected.

[0029] In this embodiment, the side of the movable plate 12 is rotatably connected to the first push rod 14, and the side of the fixed plate 13 is rotatably connected to the second push rod 15. The surfaces of the first push rod 14 and the second push rod 15 are fixedly connected to the limiting plate 16. One end of the first push rod 14 and the second push rod 15 are fixedly connected to the anti-skid pad 17. When clamping the part to be detected, the anti-skid pad 17 contacts with the part to be detected. The anti-skid pad 17 improves the anti-skid ability during clamping, so that the part to be detected is not easy to fall off. The inner bottom wall of the frame 1 is provided with a movable groove 11, and the lower surface of the movable plate 12 is fixedly connected to a mounting plate slidably connected to the movable groove 11 19. An electric wheel 20 is arranged on the mounting plate 19. A first motor 18 transmission-connected to the second push rod 15 is fixedly connected to the surface of the fixing plate 13. A second motor 25 is fixedly connected to the side of the fixing plate 13. The part to be detected is placed between the first push rod 14 and the second push rod 15. If it is a tubular part with an inner diameter larger than that of the first push rod 14 and the second push rod 15, the tubular part is sleeved on the first push rod 14 and the second push rod 15 and is blocked by the limit plate 16. Then the electric wheel 20 drives the mounting plate 19 to move, and then drives the movable plate 12 to move, so as to clamp the part to be detected, and then the electric wheel 20 is locked.

[0030] The inner wall of the frame 1 is fixedly connected with a guide box 21, and the inner wall of the guide box 21 is slidably connected with an internal thread block 22. The inner wall of the guide box 21 is rotatably connected with a threaded rod 24 that is transmission-connected to the second motor 25. The inner wall of the internal thread block 22 is threadedly connected to the threaded rod 24. The upper surface of the internal thread block 22 is fixedly connected with a partition 23. The upper surface of the partition 23 is fixedly connected with a cylinder 26, a second displacement sensor 27 and an elastic telescopic rod 33. One end of the cylinder 26, the second displacement sensor 27 and the elastic telescopic rod 33 are all fixedly connected to a lifting wheel 28. The lower surface of the lifting wheel 28 is fixedly connected with a telescopic sleeve 29 fixedly connected to the partition 23. The surface of the lifting wheel 28 is provided with a wear-resistant layer 30. The surface of the movable plate 12 is inlaid with a sliding sleeve 32. The inner wall of the sliding sleeve 32 is slidably connected to the guide box 21. The upper surface of the guide rail 2 is fixedly connected with a display screen 31, the first displacement sensor 9 and the second The data detected by the displacement sensor 27 is displayed on the display screen 31. Before the part to be detected is installed, the cylinder 26 is controlled to contract first, the elastic telescopic rod 33 is compressed, and an elastic force is generated. The second motor 25 drives the threaded rod 24 to rotate. Through the threaded cooperation between the threaded rod 24 and the internal thread block 22, the lifting wheel 28 is driven to move horizontally under the restriction of the guide box 21, and the lifting wheel 28 is moved to one end of the part to be detected. The cylinder 26 is closed, and the lifting wheel 28 is driven to rise under the action of the elastic force of the elastic telescopic rod 33, so that the lifting wheel 28 fits the part to be detected. At this time, the data of the second displacement sensor 27 is cleared and the detection is started. Then the first motor 18 drives the second push rod 15 to rotate, thereby rotating the part to be detected. At this time, under the elastic force of the elastic telescopic rod 33, the lifting wheel 28 is always in contact with the part to be detected, and the diameter change of the cylindrical part to be detected is detected by the second displacement sensor 27.

[0031] Working principle: Step 1, simultaneously control the electric push rod 7 and the cylinder 26 to retract;

[0032] Step 2: Place the part to be detected between the first push rod 14 and the second push rod 15. If the inner diameter of the tubular part is larger than that of the first push rod 14 and the second push rod 15, the tubular part is sleeved on the first push rod 14 and the second push rod 15 and blocked by the limit plate 16. Then the electric wheel 20 drives the mounting plate 19 to move, and then drives the moving plate 12 to move, so as to clamp the part to be detected, and then the electric wheel 20 is locked.

[0033] Step 3: The workpiece to be detected is fixed by the movable plate 12 and the fixed plate 13, and then the electric slider 5 drives the housing 4 to move to one end of the workpiece to be detected, and then the electric push rod 7 is closed. Under the action of the elastic force of the spring 8, the matching wheel 10 is abutted against the workpiece to be detected, and the first displacement sensor 9 is zeroed. The electric slider 5 drives the housing 4 to move, and then the matching wheel 10 moves on the surface of the workpiece to be detected. The height change of the matching wheel 10 is recorded by the displacement sensor 9, so as to measure the deformation degree of the workpiece to be detected;

[0034] Step 4, turn on the electric push rod 7 to reset the matching wheel 10, and the first motor 18 drives the second push rod 15 to rotate, thereby rotating the part to be detected, and then perform multiple tests in the same way as in step 2. After the test is completed, lift the matching wheel 10;

[0035] Step 5: Close the air cylinder 26, and under the action of the elastic force of the elastic telescopic rod 33, drive the lifting wheel 28 to rise, so that the lifting wheel 28 is in contact with the part to be detected. At this time, the data of the second displacement sensor 27 is cleared, and detection begins. Then the first motor 18 drives the second push rod 15 to rotate, thereby rotating the part to be detected. At this time, under the action of the elastic force of the elastic telescopic rod 33, the lifting wheel 28 is always in contact with the part to be detected, and the diameter change of the cylindrical part to be detected is detected by the second displacement sensor 27.

[0036] Step six, start the cylinder 26 again to drive the lifting wheel 28 to move downward, and move the position of the lifting wheel 28 to inspect other parts of the inspected part.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the invention and is not intended to limit the invention.
