Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the turning fixture of the utility model preferred embodiment; And
Fig. 2 is the structural representation of pressing plate of the turning fixture of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
In conjunction with referring to Fig. 1, turning fixture of the present utility model comprises pedestal 1, removably is fixedly connected with the stud 2 of this pedestal 1 and removably be fixedly connected with the pressing plate 3 of this pedestal 1.
Preferably, the second side at pedestal 1 also is provided with circular groove 13.The central lines of the center line of this groove 13 and pedestal 1.And this groove 13 connects with above-mentioned the first threaded connection hole 12.
The second side at pedestal 1 also vertically is provided with the second threaded connection hole 14.This second threaded connection hole 14 departs from the center line of pedestal 1 out and away, and this second threaded connection hole 14 and the first above-mentioned threaded connection hole 12 lay respectively at the both sides of the center line of pedestal 1.
The first end of above-mentioned stud 2 adopts the mode that is threaded vertically to be fixedly connected with the first threaded connection hole 12 of pedestal 1.The second end of stud 2 adopts the mode that is threaded to be fixedly connected with clamp nut 21.
Please in conjunction with reference Fig. 2, the first end of above-mentioned pressing plate 3 is provided with the draw-in groove 31 of circular arc.The second end of pressing plate 3 is provided with microscler fixing hole 32.The center line of draw-in groove 31 is coaxial with the center line of fixing hole 32.
Part to be processed is the cylinder (not shown), and this part axial ground is with meniscate inner via hole.And the first end of this part is provided with flange collar.
When needs are processed the periphery of above-mentioned part, first the first end of above-mentioned stud 2 is fixedly connected with the first threaded connection hole 12 of pedestal 1.Then, the meniscate inner via hole of part is nested with on stud 2, so that the flange collar of part first end is nested with in the groove 13 of pedestal 1.Then, clamp nut 21 is connected the second end of stud 2, thereby part is folded between pedestal 1 and the clamp nut 21 tightly.At last, the turning fixture that part is installed is installed on the lathe periphery of part processed and gets final product.
