[0035] Universal wheels are provided at the bottom of the workbench 1. After the detection is completed, the position of the detection tool can be changed by the universal wheels.

[0036] When the utility model is in operation, the workpiece is placed on the upper surface of the workbench 1, and one end of the workpiece is brought into contact with the baffle 4, and then the bidirectional threaded column 9 is driven to rotate by the driving motor 8, thereby driving the two positioning components 2 to approach the workpiece through the threaded plate 10.

[0037] When the positioning assembly 2 contacts the workpiece, the edge of the workpiece contacts and squeezes the stop pin 23, and the stop pin 23 will shrink into the positioning housing 21 according to the shape of the workpiece. At the same time, the stop pin 23 that is not squeezed by the workpiece is kept outside the side wall of the positioning housing 21 under the action of the telescopic spring 22. When the positioning assembly 2 contacts the workpiece, the connecting rod 29 will also drive the fixing rod 28 to move into the positioning housing 21. As the fixing rod 28 moves, the sliding rod 27 drives the second boss 210 to slide under the positioning tooth plate 25. When the second boss 210 contacts the first boss 26, the positioning tooth plate 25 is lifted upward, so that the positioning tooth plate 25 is stuck with the clamping teeth 212, and the position of the stop pin 23 is fixed, so that the positioning assembly 2 automatically changes from flexible clamping to hard clamping, thereby fixing the workpiece.

[0038] Then, by rotating the threaded rod 13, the movable plate 61 moves back and forth along the measuring plate, and the size of the workpiece is detected according to the distance the movable plate 61 moves on the measuring plate 5. When detecting a tubular workpiece, the sliding block 64 is moved in the slide groove through the positioning block 65. When the positioning block 65 moves to the inside of the tubular workpiece, the sliding block 64 will drive the positioning block 65 to contact the inner wall of the tubular workpiece under the action of the limit spring 63, so that the diameter and length of the tubular workpiece can be detected.

[0039] When the threaded rod 13 rotates, the worm 78 is driven to rotate, and then the bidirectional threaded rod 76 is rotated under the action of the worm wheel 77, driving the threaded sleeve 75 to move on the bidirectional threaded rod 76, and the pressure plate 72 squeezes the air storage bag 73. The gas inside the air storage bag 73 is blown to the upper surface of the measuring plate 5 through the air pipe 74 to clean the dust on the upper surface of the measuring plate 5.

[0040] After the detection is completed, the threaded rod 13 is rotated in the opposite direction to reset the movable plate 61, and the workpiece is picked up, and the workpiece is separated from the connecting rod 29. Under the action of the connecting spring 211, the connecting rod 29 drives the fixed rod 28 and the sliding rod 27 to reset, and the protrusion 210 is separated from the protrusion 1 26. Under the action of the spring rod 24, the positioning tooth plate 25 is reset downward, and the positioning tooth plate 25 releases the locking tooth 212, and the limit pin 23 can be freely extended and retracted, so that the positioning component 2 automatically changes from hard clamping to flexible clamping.

[0041] The utility model fixes the workpiece through the positioning component to realize the switching between hard clamping and flexible clamping, so that the detection tooling can be clamped and fixed according to the shape of the workpiece, thereby improving the stability of the detection tooling on the workpiece clamping, and further improving the accuracy of the detection tooling; the measuring plate is cleaned by the dust cleaning component to prevent dust and other debris from causing wear to the measuring plate scale, thereby ensuring the accuracy of the detection result and also improving the service life of the detection tooling; the measuring component is suitable for different workpieces, thereby improving the application range of the detection tooling.
