With the above technical scheme, the gear sleeve workpiece to be tested is transferred to the base plate to be tested on the production line, and is located directly below the positioning mold. At this time, the cylinder moves, and the piston rod of the cylinder extends downward, making the first movable plate downward. Movement, the first moving plate presses the four springs and compresses them at the same time, so that the springs drive the second moving plate to move downward until the positioning die enters the gear sleeve workpiece. Three of the four displacement sensors are used to detect the flatness of the gear sleeve workpiece, and the other is used to detect the positive and negative pose of the gear sleeve. If the flatness or pose of the gear sleeve workpiece does not meet the requirements, the corresponding displacement sensor will signal Send to the control system for alarm.

The invention not only has a simple and compact structure and takes up little space, but also requires no manual intervention in the whole detection process, has a high degree of automation, and has accurate and reliable detection results. The top plate, bottom plate and pillars constitute the frame. The shape of the frame is simple, the components of the frame are firmly connected, and the stability of the entire frame is good. Shaking occurs. The four guide pillars move up and down together with the second moving plate to play a guiding role to ensure that the second moving plate only moves in the vertical plane. On the one hand, the spring provides the driving force for the downward movement of the second movable plate, making the movement of the second movable plate stable; detection efficiency.

In order to simplify the structure, facilitate processing and manufacture, and reduce production costs, preferably, the first moving plate (3) and the second moving plate (4) are both rectangular flat plates.

Beneficial effects: the invention is reasonable in design, easy to implement, simple and compact in structure, small in size, small in size on the production line, and conducive to layout; the moving plate is driven downward by the cylinder and combined with four displacement sensors to detect the tooth sleeve Whether the flatness of the workpiece and the front and back pose meet the requirements, not only the detection speed is fast, the degree of automation is high, the detection process is stable, and the detection results are accurate and reliable.
