Utility model content
For the above-mentioned deficiency of the prior art, the utility model provides that a kind of clamping speed is fast, bending of accurate positioning
Pipe part inner hole Special Fixture for Machining.
To achieve the above object of the invention, the technology employed by the present utility model is
There is provided a kind of bending tubing inner bore of part Special Fixture for Machining comprising fixing pipe and support frame are set on support frame
It is equipped with mounting hole, fixing pipe plugs in mounting hole, and the positioning screw fixing pipe for being fastened and fixed pipe is provided on mounting hole
On offer slot, and the end of fixing pipe is provided with positioning table, and the fastening for fastening part to be processed is provided in fixing pipe
Screw.
Further, three positioning screws are provided on mounting hole, three positioning screws are arranged at even circumferential；Fixing pipe
On be provided with three fastening screws, three fastening screws are arranged at even circumferential.
Further, positioning screw and fastening screw are all made of end face soket head cap screw.
Further, one end of slot is scarf.
Further, the end of positioning screw is provided with end rubber.
The utility model has the following beneficial effects: this programme is the special fixture that parts like bent pipes process inner hole on lathe,
Part is plugged in fixing pipe by slot, is contacted end face to be processed with the positioning table being arranged in fixing pipe, is positioned；Rotation
The fastening screw being arranged on pipe is fastened, part is fixed in fixing pipe；Fixing pipe is fixed on the three chucking chuck of lathe, branch
Support is fixed on lathe, is processed to inner bore of part；By adjusting three positioning screws being arranged on mounting hole, so that solid
Fixed pipe is located on the rotation center of three chucking chuck, it is ensured that machining accuracy；Staff can also by finely tune three fastening screws,
It is located at the machining center of part on the rotation center of three chucking chuck, further ensures that machining accuracy.It is straight due to fastening screw
The curved face contact with bend pipe is connect, has given part one power contrary with tool feeding in process, has effectively prevent zero
Part moves back, it is ensured that machining accuracy.
The fixation and positioning to part are realized using two groups of screws, and accurate fixed to realize in such a way that tripartite finely tunes
Position, and adjust process simply, conveniently；Fastening screw and positioning screw are all made of end face soket head cap screw, facilitate staff
Renewal part and adjusting screw；The end rubber of positioning screw end setting can effectively reduce positioning screw to the wound of fixing pipe
Evil, the working life of lifting clamp；The slot of scarf makes the handling of part more convenient, improves working efficiency.This reality
Reasonable with new design, structure is simple, and fixture is fast to parts fixation speed, clamps positioning reliably, and fixture design is simple to be easy system
Make, turning inner hole is high-efficient, and input cost is few.

Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the column of protection.
As shown in Figure 1 to Figure 3, bending tubing inner bore of part Special Fixture for Machining includes fixing pipe 3 and support frame 1, support
Mounting hole 7 is offered on frame 1, fixing pipe 3 plugs in mounting hole 7, and three positioning screws are provided on mounting hole 7, and three fixed
Position screw 2 is arranged at even circumferential, and the end of three positioning screws 2 is provided with end rubber；Slot is offered in fixing pipe 3
5, one end of slot 5 is set as scarf；The end of fixing pipe 3 is provided with positioning table 9, and three are provided in fixing pipe 3
Fastening screw 6, three fastening screws 6 are arranged at even circumferential；Positioning screw 2 and fastening screw 6 are all made of hexagonal spiral shell in end face
Nail.
When implementing, the slot 5 that part 4 is opened up from fixing pipe 3 plugs in fixing pipe 3 this programme, makes end to be processed
Face is contacted with the positioning table 9 being arranged in fixing pipe 3, is positioned；The fastening screw 6 being arranged on pipe 3 that is tightened consolidates part 4
Due in fixing pipe 3；Fixing pipe 3 is fixed on the three chucking chuck of lathe, and support frame 1 is fixed on lathe, to inner bore of part 8 into
