Technical Field

[0001] This utility model belongs to the field of gear testing technology, specifically relating to a torque testing fixing device. Background Technology

[0002] Gears are toothed mechanical parts that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Modern gear technology has reached the following levels: gear module 0.004 to 100 mm; gear diameter from 1 mm to 150 m; power transmission up to hundreds of thousands of kilowatts; speed up to hundreds of thousands of revolutions per minute; and the highest circumferential speed up to 300 m / s.

[0003] During the component manufacturing process, multiple gear components need to be assembled and rotated to perform torque tests on the teeth. Because there are many points in the assembly of the components, component slippage is likely to occur, and a single component cannot meet the torque test requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a torque detection and fixing device with the advantage of accurate detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a torque detection and fixing device, comprising a base plate, a base fixedly connected to the top outer wall of the base plate, a transmission column rotatably connected to the outer wall of the base, a transmission gear inserted into the outer wall of the transmission column, a first positioning column fixedly connected to the outer wall of the base, a second positioning column fixedly connected to the outer wall of the base, a third positioning column fixedly connected to the outer wall of the base, a pressure block provided on the top outer wall of the base, a fixing pin connected in series between the pressure block and the inner wall of the base, and a connecting column inserted into the top of the transmission column.

[0006] The above technical solution facilitates fixation. By setting the first, second, and third positioning posts for fixed connection, the manufactured gear components can be accurately positioned, and the gear sets can mesh with each other. After the product gears are placed, the transmission gear is inserted into the transmission post, then the pressure block is placed on top and fixed with the fixing pin. Then the connecting post is inserted into the top of the transmission post, and finally the torque of the gear set can be determined by testing with a torque wrench.

[0007] Preferably, handles are fixedly connected to both sides of the base plate, and limit posts are fixedly connected to the outer wall of the base.

[0008] The above technical solution can achieve the effect of movement. The handle on the outside of the base plate can assist in moving the equipment, and the limiting post can be used to position the pressure block.

[0009] Preferably, the outer wall of the transmission column is fixedly connected with teeth, and the top of the transmission column is provided with a ridge.

[0010] The above technical solution can serve as a connection, and the teeth and edges can be used to fix the transmission gear and the connecting column.

[0011] Preferably, the inner wall of the transmission gear meshes with the teeth in the transmission column.

[0012] Through the above technical solution, the meshing between the inner wall of the transmission gear and the teeth in the transmission column allows the transmission gear to rotate together when the transmission column rotates.

[0013] Preferably, the bottom of the inner wall of the connecting column is inserted into the edge of the transmission column.

[0014] With the above technical solution, the edge fits into the connecting column, which can drive the transmission column to rotate together when the connecting column rotates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up the first, second, and third positioning posts with fixed connections, the manufactured gear parts can be accurately positioned, and the gear sets can mesh with each other. After the product gears are placed, the transmission gear is inserted into the transmission post, then the pressure block is placed on top and fixed with the fixing pin. Then the connecting post is inserted into the top of the transmission post, and finally the torque of the gear set can be determined by testing with a torque wrench.

[0017] 2. The handle on the outside of the base plate can assist in moving the equipment. The limiting post can be used to position the pressure block. The teeth and edges can be used to fix the transmission gear and connecting post. Attached Figure Description
