[0002] Gear detection is an important step in the gear production process, usually sampling in the same batch of several gears, and detecting the sample gear in multiple types to ensure that the gears in the same batch are qualified.

[0003] The existing gear outer circle precision detection mostly uses a lever micrometer, and in the detection process, the detection end of the lever micrometer is in surface contact with the maximum diameter of the gear, then the gear is driven to rotate by the gear clamp, so that the gear rotates in the state of contacting the lever micrometer, and the gear contacts the detection end of the lever micrometer during rotation, and the lever micrometer displays the error of the gear outer circle, but if the gear outer circle error is large, the intermittent gear tooth part may be damaged, which affects the subsequent gear detection work.

[0006] Further, the pipe clamp includes a connecting part and a clamp part, the connecting part is a circular column structure, the clamp part extends outward along the connecting part, and the overall structure is a pipe clamp structure, so that the overall structure can be fixed by the pipe clamp and can be adjusted at will to adapt to different use conditions.

[0007] Further, the input end of the lever micrometer, i.e. the measuring head, faces the direction of the board.

[0008] Further, the torsional spring rotates in the direction of driving the board towards the gear clamp, so that the board can contact the gear fixed by the gear clamp.

[0009] Further, the plate and the direction of the plate towards the gear clamp are provided with an arc surface matched with the gear, ensuring that the plate can smoothly contact with the gear.

[0010] Further, the measuring head of the lever micrometer is provided with a spherical shape at one end close to the plate, reducing the contact area of the lever micrometer and the plate, and making the contact of the lever micrometer and the plate more smooth.

[0011] Further, the plate is a flexible copper sheet structure, and the side close to the gear clamp is coated with a wear-resistant coating, so that the plate can deform when receiving a larger impact, and the impact force is transmitted through deformation, avoiding the precision of the gear.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model discloses a lever micrometer and gear clamp between setting up the plate, and the plate is close to the gear clamped by the gear under the action of torsion spring all the time, when the gear rotates, always contact with the plate, if the gear's outer circle precision exists error and directly push the plate and move, and the detection end of lever micrometer only needs to contact the plate to detect the outer circle precision of the gear, and the contact surface of the plate and the detection end of lever micrometer is smooth and even, so as not to cause the damage of lever micrometer, when detecting different model size gears, only need to guarantee that the plate contacts the gear and the lever micrometer at the same time, and can be used, and the adaptation ability is higher.
