Description

Technical Field

[0001] The utility model relates to the field of drive shaft manufacturing and processing, in particular to a positioning mechanism for drive shaft processing. Background Art

[0002] When processing the drive shaft, a clamping mechanism is needed to support both ends of the drive shaft to make it stand upright, and the clamping mechanism must be against the center of both ends of the drive shaft to prevent deviation. Otherwise, deviation will occur during processing. It is time-consuming to align the center of the drive shaft with the clamping mechanism each time, which reduces work efficiency. Utility Model Content

[0003] The utility model aims to provide a positioning mechanism for driving shaft processing, which has the advantage of facilitating the clamping mechanism to abut against the center of the driving shaft.

[0006] By adopting the above technical solution, the drive shaft is placed vertically on the clamping mechanism of the processing table so that the drive shaft is against the backing plate. Under the action of the backing plate, the clamping mechanism clamps the centers of both ends of the drive shaft, saving the time required for alignment and improving work efficiency.

[0007] Preferably, the backing plate is provided with a slide groove, and the screw rod passes through the backing plate slide groove.

[0008] By adopting the above technical solution, the bolts are loosened, the backing plate is moved horizontally, and the distance between the backing plate and the clamping mechanism is adjusted, so that when drive shafts of different diameters are against the backing plate, the clamping mechanism can be against the center of both ends.

[0009] Preferably, there are two support plates which are sleeved on the screw rod, and nuts are provided on the upper and lower sides of each support plate.

[0010] By adopting the above technical solution, the two support plates respectively support the upper and lower ends of the driving shaft, so that the driving shaft can be better maintained in a vertical state.

[0011] Preferably, the backing plate surface is red.

[0012] By adopting the above technical solution, the resolution is improved and it is easy to find the support board.

[0013] Preferably, the surface of the back plate in contact with the driving shaft is arc-shaped.

[0014] By adopting the above technical solution, the fit between the backing plate and the driving shaft is increased, so that the driving shaft can better lean against the backing plate.

[0015] Preferably, one end of the screw rod away from the top of the processing table is fixedly connected with a terminal.

[0016] By adopting the technical solution, it is convenient to twist the screw rod to remove and install it from the workbench.

[0017] Preferably, both side edges of the backing plate are S-shaped, and both sides of the end of the backing plate close to the clamping mechanism are recessed inwards.

[0018] By adopting the technical solution, the fulcrum points of the backing plate are increased, making it easier to move the backing plate. BRIEF DESCRIPTION OF THE DRAWINGS
