[0029] The left clamping plate 2 is fixedly mounted on the left side wall of the top of the base 1, and the right clamping plate 3 is slidably mounted on the right side wall of the top of the base 1.

[0030] An error detection mechanism 6 is installed on the top wall of the base 1, and the error detection mechanism 6 is located between the left clamping plate 2 and the right clamping plate 3. During the detection process, the part is placed on the top of the base 1, so that the part is between the left clamping plate 2 and the right clamping plate 3, and the error detection mechanism 6 is located inside the part. By moving the right clamping plate 3, the left clamping plate 2 and the right clamping plate 3 are in contact with both sides of the part, and the outer diameter of the part is detected and measured (a scale line is provided on the top rear side wall of the base 1);

[0031] See also Figure 1 , Figure 2 and Figure 3 The error detection mechanism 6 includes a mounting plate 61 mounted on the top wall of the base 1, a mounting hole 67 is provided on the top wall of the mounting plate 61, a driving motor 66 is installed at the bottom of the inner cavity of the mounting hole 67, a mounting sleeve 62 is installed on the top output shaft of the driving motor 66, a connecting rod 63 is slidably inserted into the rear side of the inner cavity of the mounting sleeve 62, a guide block 65 is installed at the rear end of the connecting rod 63, and a display mechanism 68 is installed at the front side of the inner cavity of the mounting sleeve 62. During the process of fitting the left clamping plate 2 and the right clamping plate 3 with the two sides of the part, the connecting rod 63 is moved to make the guide block 65 contact with the inner wall of the part, and then The driving motor 66 works, driving the installation sleeve 62, the connecting rod 63 and the guide block 65 to rotate. During the rotation process, if the parts are deformed and sunken due to the action of the left clamping plate 2 and the right clamping plate 3, the connecting rod 63 will move into the inner cavity of the installation sleeve 62, and the touch switch 682 will be pressed to make the external warning light light up, which is used to remind the staff so that people can understand the error of the detection in time. If the parts are not deformed, the connecting rod 63 and the guide block 65 will rotate normally without moving. The electrical equipment involved in the device is electrically connected to the external power switch through the wire;

[0032] See also Figure 2 and Figure 3 The display mechanism 68 includes a support spring 687 installed between the front end of the connecting rod 63 and the front side of the inner cavity of the mounting sleeve 62, a mounting block 681 is installed on the left inner wall of the mounting sleeve 62, and a touch switch 682 is installed on the rear side wall of the mounting block 681, and the touch switch 682 is located on the front side of the connecting rod 63, and the touch switch 682 is electrically connected to the external warning light;

[0034] Embodiment 2:

If the detected part is deformed and concave, the supporting screw 688 fixes the connecting rod 63, so that the connecting rod 63 cannot move inward, so that the pressure of the guide block 65 passing through the concave area of ​​the part is relatively large, so that the friction between the two increases, and the speed of the guide block 65 passing through the concave area decreases, so that the centrifugal force on the elastic telescopic rod 6812 is reduced, and the outward movement of the conductive sheet 6811 is reduced, so that the external indicator light does not light up, and it can also remind the staff. If the part is not concave, the friction force on the guide block 65 is the same, so that the centrifugal force on the elastic telescopic rod 6812 remains unchanged, so that the annular conductive sheet 6810 is in continuous contact with the conductive sheet 6811, and the external indicator light continues to light up;

[0036] Compared with Example 1, components such as support screw 688 and mounting plate 689 are added. If the detected part is deformed and concave, the support screw 688 will fix the connecting rod 63, so that the connecting rod 63 cannot move inward, so that the pressure of the guide block 65 passing through the concave area of ​​the part is relatively large, and the friction between the two is increased, so that the speed of the guide block 65 passing through the concave area is reduced, thereby reducing the centrifugal force on the elastic telescopic rod 6812 and reducing the outward movement of the conductive sheet 6811, so that the external indicator light is not on, and it can also remind the staff, so that the display mechanism 68 can also be composed of these components to increase the display method.

[0037] Embodiment 3:

[0038] See also Figure 1 , Figure 2 and Figure 4 On the basis of Example 1, the mounting sleeve 62 includes two sets of sleeve bodies, and the side walls of the two sets of sleeve bodies close to each other are clamped, so that the mounting sleeve 62 can be split into two parts, and the connecting rod 63 includes an insertion rod 631 slidably inserted in the rear side of the inner cavity of the mounting sleeve 62, and a screw hole is provided on the rear side wall of the insertion rod 631, and an adjusting screw 632 is screwed on the rear side of the inner cavity of the screw hole, and a support rod 633 is installed at the rear end of the adjusting screw 632, and the rear end of the support rod 633 is connected to the front side wall of the guide block 65, and the support rod 633 is rotated to rotate the adjusting screw 632 in the inner cavity of the screw hole, so as to change the length of the connecting rod 63, so that the error detection mechanism 6 is suitable for parts with different inner diameters;

[0039] See also Figure 1 , a slider is installed on the bottom wall of the mounting plate 61, a slide groove 64 is opened on the top wall of the base 1, and the slider is slidably inserted in the inner cavity of the slide groove 64, so that the mounting plate 61 can move above the base 1, so that the position of the error detection mechanism 6 can be adjusted, which is suitable for detecting parts of different specifications, and a threaded sleeve is installed on the bottom wall of the mounting sleeve 62, and a mounting screw is installed on the top output shaft of the driving motor 66, and the mounting screw is screwed in the inner cavity of the threaded sleeve.

[0040] Compared with the first embodiment, components such as an insert rod 631, an adjusting screw rod 632 and a supporting rod 633 are added, and the length of the connecting rod 63 is changed, so that the error detection mechanism 6 is suitable for the detection of parts with different inner diameters.

[0041] Working principle: During the detection process, the part is placed on the top of the base 1 so that the part is between the left clamping plate 2 and the right clamping plate 3, and the error detection mechanism 6 is placed inside the part. By moving the right clamping plate 3, the left clamping plate 2 and the right clamping plate 3 are in contact with both sides of the part, and the outer diameter of the part is detected and measured. In this process, the connecting rod 63 is moved to make the guide block 65 contact with the inner wall of the part, and then the driving motor 66 works to rotate the mounting sleeve 62, the connecting rod 63 and the guide block 65. During the rotation process, if the part is deformed and concave due to the action of the left clamping plate 2 and the right clamping plate 3, the connecting rod 63 will move into the inner cavity of the mounting sleeve 62, and the touch switch 682 will be pressed to make the external warning light light up, which is used to prompt the staff so that people can promptly understand the situation of detection errors.
