The servo A reciprocating screw 10 is mounted on the output end of the motor 9 through a coupling, a connecting frame 11 is mounted in the middle of the reciprocating screw 10, a screw slot 20 is penetrated through the middle of the connecting frame 11, two moving blocks 12 adapted to the moving slot 7 are fixedly mounted on the back of the base 1, an electric telescopic rod 13 is arranged on the top of the connecting frame 11, a square plate 14 is fixedly mounted on the bottom of the output end of the electric telescopic rod 13, a fixed plate 15 is arranged at the bottom of the square plate 14, an inner hole detector 18 is fixedly mounted on the bottom of the fixed plate 15, and support columns 19 are fixedly mounted all around the bottom of the base 1.

[0027] Furthermore, the clamping seats 4 are all fixedly mounted on the output end of the electric push rod 3 and are all slidably connected to the base 1 in the slide groove 2 through the slider 5.

[0028] Furthermore, protective pads 6 are provided on the tops of the two clamping seats 4, and the material of the protective pads 6 is rubber material. Advantages: the output ends of the two electric push rods 3 drive the two clamping seats 4 to slide toward the two ends of the automobile parts in the slide groove 2 through the sliders 5 respectively, and the distance between the two clamping seats 4 is adjusted according to the diameter of the automobile parts to clamp and fix the automobile parts. At the same time, the protective pads 6 made of rubber material can protect the two sliders 5 when clamping the automobile parts to prevent unnecessary clamping injuries caused by hard contact. Therefore, the device can perform protective clamping and fixing on automobile parts of different diameters, bringing convenience to the operator.

[0029] Furthermore, the connecting frame 11 is sleeved on the middle part of the reciprocating screw 10 through the screw groove 20 and is slidably connected to the base 1 in the moving groove 7 through the moving block 12. Advantages: the reciprocating screw 10 is driven to rotate by the output end of the servo motor 9. When the reciprocating screw 10 rotates, it drives the connecting frame 11 to slide left and right in the moving groove 7 through the screw groove 20 through the moving block 12, so that the inner hole detector 18 is adjusted to the position of the inner hole of the automobile part. Then, the outlet end of the electric telescopic rod 13 drives the inner hole detector 18 to rise and fall downward through the square plate 14 and the fixed plate 15 to enter the inner hole of the automobile part for measurement, so that the operator can automatically adjust the inner hole detector 18 to different inner holes of the automobile part for measurement, thereby providing convenience for the operator and reducing the workload.

Advantages: by setting the number of support legs 26 to four and distributing them equidistantly in a matrix array around the bottom of the base 1, the four support columns 19 can be in a balanced state when supporting the base 1, preventing it from unnecessary tilting. At the same time, setting the bottoms of the support columns 19 to a frosted state can increase the frictional resistance between the four support columns 19 and the ground when supporting the base 1, which can prevent unnecessary autonomous shaking when supporting the base 1, thereby improving the stability of the device when in use.

[0033] Working principle: When in use, firstly, the output ends of the two electric push rods 3 drive the two clamping seats 4 to slide in the slide groove 2 toward the two ends of the automobile parts through the slider 5, and the distance between the two clamping seats 4 is adjusted according to the diameter of the automobile parts, so as to clamp and fix the automobile parts. At the same time, the protective pad 6 made of rubber material can be used to protect the automobile parts when the two sliders 5 clamp them, so as to prevent unnecessary clamping injuries caused by hard contact. Therefore, the device can perform protective clamping and fixing of automobile parts with different diameters, bringing convenience to the operator. After fixing, the reciprocating screw 10 can be driven to rotate by the output end of the servo motor 9. When the reciprocating screw 10 rotates, it drives the connecting frame 11 to slide left and right in the moving groove 7 through the screw slot 20 through the moving block 12, so that the inner hole detector 18 is adjusted to the position of the inner hole of the automobile part, and then the electric The outlet end of the telescopic rod 13 drives the inner hole detector 18 to rise and fall downward through the square plate 14 and the fixed plate 15 to enter the inner hole of the automobile part for measurement, so that the operator can automatically adjust the inner hole detector 18 to different inner holes of the automobile part for measurement, thereby providing convenience for the operator and reducing the workload. When it is necessary to replace and clean the inner hole detector 18 that has been used for too long, the two bolts 17 can be removed by rotating counterclockwise in each group of corresponding thread grooves 16 to release the fixation of the square plate 14 and the fixed plate 15, and then the inner hole detector 18 is separated and removed from the square plate 14 through the fixed plate 15, so that the operator can replace and clean the inner hole detector 18 that has been used for too long, preventing it from being damaged and unable to be replaced and inconvenient to clean due to long-term use, which will bring unnecessary impact on normal measurement work.
