Abstract
The invention relates to a special fixture for a coupling fork keyseat. The special fixture comprises a base plate and a rotating disc, two positioning pins are arranged on the base plate and the rotating disc, a rotating disc press plate fixed by screws is arranged on the rotating disc, a positioning ring for workpiece positioning is arranged on the rotating disc, and a workpiece press plate fixed by screws is arranged in the middle of the positioning ring. The special fixture for the coupling fork keyseat has the advantages that the special fixture for the coupling fork keyseat is novel in structure, reasonable and good in manufacturability and reliability, size precision and position precision are guaranteed easily, and the problem of asymmetry of a keyseat and a spigot of an existing fixture is effectively solved.
Description
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of coupling yoke keyseat special fixture.
Background technology
Raising along with machine finish, in order to reduce position error, improve machining accuracy, the accuracy of manufacture to anchor clamps requires corresponding raising, keyseat generally adopts professional anchor clamps at present, but present special fixture is complex structure not only, and poor operability, need to be improved coupling yoke keyseat special fixture.
Summary of the invention
Technical problem to be solved by this invention is that the coupling yoke keyseat special fixture of a kind of manufacturability and good reliability is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: this coupling yoke keyseat special fixture, comprise base plate and rotating disc, be provided with two fastening screws on described base plate and the rotating disc, be provided with on the described rotating disc by the fixing pressure rotation plate of screw, be provided with the centring ring of positioning workpieces on the described rotating disc, be provided with in the middle of the described centring ring by the fixing pressure work plate of screw.
Preferably, be flexible connection between described base plate and the rotating disc.
Compared with prior art, usefulness of the present invention is: this coupling yoke keyseat special fixture novel structure, rationally, manufacturability and good reliability, dimensional accuracy and positional precision easily guarantee, have effectively solved existing anchor clamps and have had keyway and seam AXIALLY SYMMETRIC PROBLEMS.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is coupling yoke keyseat special fixture structural representation of the present invention;
Fig. 2 is coupling yoke keyseat special fixture structural representation top view of the present invention.
Among the figure: 1, base plate; 2, latch; 3, rotating disc; 4, workpiece; 5, centring ring; 6, press work plate; 7, screw; 8, press the rotation plate.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of coupling yoke keyseat special fixture shown in Fig. 1,2, comprise base plate 1 and rotating disc 3, be provided with two fastening screws 2 on described base plate 1 and the rotating disc 3, be provided with on the described rotating disc 3 by screw 7 fixing pressures and rotate plate 8, be provided with the centring ring 5 of positioning workpieces 4 on the described rotating disc 3, be provided with the pressure work plate 6 of fixing by screw 7 in the middle of the described centring ring 5.After milling a side switch groove, unclamp and press rotation plate (8), extract two latches (2), behind the Rotate 180 degree, again latch (2) is inserted in two fastening screw holes, with pressing rotating disc (8) to be compressed firmly by two screws (7), mill the opposite side keyway.
Be flexible connection between described base plate 1 and the rotating disc 3.
This coupling yoke keyseat special fixture novel structure, rationally, manufacturability and good reliability, dimensional accuracy and positional precision easily guarantee, have effectively solved existing anchor clamps and have had keyway and seam AXIALLY SYMMETRIC PROBLEMS.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
