Through adopting above-mentioned technical scheme, because the existence of elastic component, consequently the articulated arm uses the trend that has the removal, and then makes the runner wheel have the trend of removal to it has the tensioning effect to make can always to the belt.

The present application may be further configured in a preferred example to: the tensioning seat on still rotate and be connected with the auxiliary wheel, the belt cover establish the auxiliary wheel on, auxiliary wheel, rotation wheel and the motor be triangular distribution.

Through adopting above-mentioned technical scheme, in use, auxiliary wheel, rotation wheel and motor are triangular distribution for the transmission effect of belt is better.

The present application may be further configured in a preferred example to: the elastic piece is a spring, one end of the spring is abutted against the hinged arm, and the other end of the spring is abutted against the tensioning seat.

By adopting the technical scheme, the articulated arm always tends to move.

The present application may be further configured in a preferred example to: the machine table is further provided with a supporting seat, a placing groove is formed in the supporting seat and used for placing workpieces, an opening of the placing groove is in a V shape, and the belt is arranged above the placing groove and used for applying pressure to the workpieces.

Through adopting above-mentioned technical scheme, when using, exert pressure to the work piece through the belt to drive the work piece through the belt and rotate, the flexibility of belt is better, makes the work piece rotatory steady.

Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Referring to fig. 1-3, for a transmission grinding fixture disclosed in this application, including board 1, be equipped with hold-down mechanism 2 on board 1, hold-down mechanism 2 includes pushing down subassembly and driving piece, and the driving piece includes motor 21 and belt 22, and motor 21 fixed mounting is in one side of board 1. The hold-down assembly includes a lift member 24 and a hold-down member including a hold-down shoe 23 and a turning wheel 33. The lifting piece 24 comprises an air cylinder which is fixedly arranged on the machine table 1, and the lower pressing seat 23 is connected with the air cylinder and driven by the air cylinder to lift.

The lower pressing seat 23 is further provided with a tensioning assembly, the tensioning assembly comprises a tensioning seat 31 and an articulated arm 32, the tensioning seat 31 is articulated with the articulated arm 32, the tensioning seat 31 is further provided with an elastic member 35, in this embodiment, the elastic member 35 is a spring, one end of the elastic member 35 is fixedly connected with the tensioning seat 31, and the other end of the elastic member 35 is fixedly connected with the articulated arm 32 and is in a compressed state. A swivel wheel 33 is rotatably mounted on the end of the hinge arm 32 remote from the tensioning seat 31.
