Detailed Description

The following further describes a specific embodiment of the positioning device for producing a transmission shaft according to the present invention with reference to fig. 1 to 3. The utility model relates to a positioner is used in transmission shaft production is not limited to the description of following embodiment.

Example 1:

this example gives: a positioning device for transmission shaft production comprises a cylinder assembly 1, the cylinder assembly 1 is electrically connected with a power supply, a top plate 3 is fixed below the cylinder assembly 1 through bolts, the top plate 3 and a bottom plate 7 are both of a plate-shaped structure, the top plate 3 and the bottom plate 7 are respectively fixed above and below a vertical plate 5, a shaft lever 2 is arranged below the top plate 3, a first clamp 4 is arranged below the shaft lever 2, the first clamp 4 is composed of a connecting post 41, a transverse plate 42, a clamping block 43, a first buffer mechanism 44 and a second buffer mechanism 45, the connecting post 41 is arranged at the axle center above the transverse plate 42, the clamping block 43 is arranged at the axle center at the bottom end of the transverse plate 42, the first buffer mechanism 44 is arranged at one side inside the clamping block 43, the second buffer mechanism 45 is arranged at the other side inside the clamping block 43, a second clamp 6 is arranged below the first clamp 4, the bottom plate 7 is arranged below the second clamp 6, the bottom plate 7 and the inner side of the top plate 3 are provided with the vertical plate 5, the riser 5 is platelike structure, and the riser 5 is close to 7 one side axle centers departments of bottom plate and is provided with the hole of rectangle, through the setting in rectangle hole, can be so that the better fixed stability of going on of transmission shaft.
