Abstract
The utility model belongs to utility, and in particular to a kind of processing tool for cantilever structure.Including pedestal (1), taper type expansion pin (2), swollen nail (3)；The utility model is for solving the problems, such as the tooling trembled and designed in cantilever structure process.The tooling can effectively solve the problems, such as trembling in cantilever structure processing, and enhancing processing rigidity avoids dimensional accuracy caused by trembling as processing overproof.The tool structure is simple, and it is convenient to load and unload, and can once realize the quick positioning of cantilever structure part, clamping substantially increases processing efficiency.
Description
Technical field
The utility model belongs to utility, and in particular to a kind of processing tool for cantilever structure.
Background technique
Shell part is widely used in airborne product, such design of part is complicated, and dimensional accuracy is high, and two sides are big
End end face is cantilever structure, easily generates and trembles in process, causes parts size precision overproof.Traditional clamping side
Method, generalling use cushion block will level up at cantilever, then is compressed by pressing plate and carry out clamping, not only need repeatedly to dismantle in process
Pressing plate, while the surface leveled up is it is difficult to ensure that high consistency, machining accuracy and efficiency all suffer from stern challenge.
Summary of the invention
The purpose of this utility model is: designing a kind of processing tool for cantilever structure, is solved by the tooling outstanding
Problem of trembling in arm type structure process, enhancing processing rigidity, improves clamping efficiency, and preventing from trembling due to processing leads to zero
Part dimensional accuracy is overproof, while by the cooperation of swollen nail and taper type expansion pin, the primary Set and Positioning for realizing part reduces
The time of Manual Switch pressing plate, improve processing efficiency and precision.
Technical solution of the present invention:
A kind of processing tool for cantilever structure, it is characterised in that: including pedestal 1, taper type expansion pin 2, swollen nail
3；Pedestal 1 is plinth, above there is pinhole, corresponding with part lead to the hole site, and taper type expansion pin 2 passes through part cantilever design
Through-hole, lower end be inserted into pedestal pinhole in；Swollen nail 3 is by being threadedly engaged in the internal thread hole for screwing in taper type expansion pin 2.
The taper type expansion pin 2 is 0.01-0.015 with part cantilever through-hole, pedestal pinhole fit clearance, and outer circle is
Taper type, taper ratio 1:20, one end is equipped with threaded hole, and is equipped with flat recess.
The swollen nail 3 is taper screw, tail portion taper 1:20, external screw thread and taper type expansion pin screw-internal thread fit.
Advantageous effect of the invention:
1) tooling can effectively solve the problems, such as trembling in cantilever structure processing, and enhancing processing rigidity is avoided due to adding
Dimensional accuracy caused by work is trembled is overproof.
2) tool structure is simple, and it is convenient to load and unload, and has certain applicability for solving same problems.
3) tooling can once realize the quick positioning of cantilever structure part, and clamping substantially increases processing efficiency.
Detailed description of the invention
Fig. 1 is the half sectional view of the practical tooling,
Wherein: 1- pedestal, 2- taper type expansion pin, 3- is swollen nail.
Specific embodiment
The following further describes the present invention with reference to the drawings:
As shown in Figure 1, a kind of processing tool for cantilever structure, including pedestal 1, taper type expansion pin 2, swollen nail 3；
Pedestal 1 is plinth, above there is pinhole, corresponding with part lead to the hole site, and taper type expansion pin 2 passes through part cantilever design
Through-hole, lower end are inserted into the pinhole of pedestal；Swollen nail 3 is by being threadedly engaged in the internal thread hole for screwing in taper type expansion pin 2.
Pedestal: for plinth, above there is pinhole, identical as part clear size of opening, and position is corresponding.
Taper type expansion pin: being 0.01-0.015 with part cantilever through-hole, pedestal pinhole fit clearance, pin outer circle is
Taper type, taper ratio 1:20, one end brill, tapping thread hole cut a flat recess.
Swollen nail: for taper screw, tail portion taper 1:20, external screw thread and taper type expansion pin screw-internal thread fit, pass through screw-in
Positioning compression effect is realized in taper type expansion pin threaded hole.
Working principle:
Step 1: will be placed on pedestal at part cantilever first, hole in piece part is corresponding with pedestal hole site when processing；
Step 2: taper type expansion pin is inserted into pedestal inner hole by through-hole at cantilever, compress；
Step 3: screw in swollen nail in taper type expansion pin other end opening, until taper type expansion pin is by part cantilever
It is compressed with pedestal.
Through production practices, which effectively enhances the processing rigidity of cantilever structure, reduces since processing is trembled pair
In the influence of parts size precision, while clamping efficiency is improved, resetting misses caused by eliminating because of cushion block uneven surface
Difference ensure that processing quality.
