Abstract
The utility model belongs to the field of a drilling machine, and particularly relates to a flywheel housing drilling machine jig. The flywheel housing drilling machine jig comprises a drilling machine worktable, wherein the drilling machine worktable is provided with a workpiece fixing shaft, a fixed nut is arranged on the end part of the workpiece fixing shaft and is used for fixing a workpiece, and the flywheel housing drilling machine jig also comprises a backing plate, the middle part of the backing plate is provided with a hole, the hole is arranged on the side edge of the backing plate and extends through to the other side of the backing plate, and the backing plate can be buckled onto the workpiece fixing shaft through the hole which extends through one side edge of the backing plate. By utilizing the backing plate with the hole extending through one side edge, not only can the backing plate be buckled onto the workpiece fixing shaft and be used for fixing the workpiece, but also the backing plate is unnecessary to install by completely disassembling the fixed nut and then putting in the banking plate, so that the boring efficiency of a flywheel housing can be greatly improved, and the physical power of an operator can be saved.
Description
Technical field
The utility model belongs to drilling machine field, is specifically related to a kind of bell housing drill jig.
Background technology
In automotive field, a lot of accessories need to punch, especially in the process of bell housing, on bell housing, need to beat a lot of holes, the centre of bell housing is with very large hole, be difficult for being fixed, need to use large pad to be stuck between bell housing and hold-down nut, but pad snaps in workpiece fixed axis, all need now hold-down nut to be backed out at every turn, then pad is snapped between hold-down nut and bell housing, block fixing, then carry out drilling operation, punch comparatively easy, but the time of at every turn fixing bell housing accounts for the major part of whole punching time, cause the inefficiency of punching, and the quality of bell housing is very large, cause the very large waste of human cost.
Utility model content
For solving the above-mentioned shortcoming of prior art, the utility model provides a kind of bell housing drill jig, has simplified the fixing step of bell housing, has greatly improved the efficiency of drilling machine punching.
The utility model is achieved through the following technical solutions:
A kind of bell housing drill jig, comprise that Drilling machines bench, Drilling machines bench are provided with workpiece fixed axis, workpiece fixed axis end is provided with hold-down nut, be used for fixing workpiece, also comprise backing plate, in the middle of backing plate, be provided with hole, hole is opened in backing plate side and is through to one side of backing plate, and backing plate can be buckled on workpiece fixed axis by the hole of running through a side of backing plate.
The diameter at center, described hole is greater than the aperture at backing plate side.
Add man-hour, hold-down nut is screwed in to workpiece fixed axis, because hole in the middle of bell housing is larger, bell housing penetrates workpiece fixed axis, and pad is buckled on the workpiece fixed axis between bell housing and hold-down nut by the hole of pad, blocks bell housing, nut is tightened, bell housing is fixed, after having bored hole, hold-down nut is unscrewed, take off pad, the bell housing processing is taken off, change the bell housing not processing, process.
The beneficial effect that this practicality is new: the utility model is by using with running through the pad pad of lateral orifices on one side, both can be stuck in fixation workpiece on workpiece fixed axis, when installation, do not need hold-down nut all to unload and put into again pad yet, greatly improve the efficiency of bell housing boring, the muscle power of also having saved operator.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
A kind of bell housing drill jig, comprise that Drilling machines bench 1, Drilling machines bench 1 are provided with workpiece fixed axis 3, workpiece fixed axis 3 ends are provided with hold-down nut 4, be used for fixing workpiece, also comprise backing plate 2, in the middle of backing plate 2, be provided with hole 5, hole 5 is opened in backing plate 2 sides and is through to one side of backing plate 2, and backing plate 2 can be buckled on workpiece fixed axis 3 by the hole 5 of running through 2 one sides of backing plate.
The diameter at 5 centers, described hole is greater than the aperture at backing plate 2 sides.
Add man-hour, hold-down nut 4 is screwed in to workpiece fixed axis 3, because hole in the middle of bell housing is larger, bell housing penetrates workpiece fixed axis 3, and pad 2 is buckled on the workpiece fixed axis 3 between bell housing and hold-down nut 4 by the hole 5 of pad, blocks bell housing, nut 4 is tightened, bell housing is fixed, after having bored hole, hold-down nut 4 is unscrewed, take off pad 2, the bell housing processing is taken off, change the bell housing not processing, process.
