Abstract

The utility model relates to an auxiliary device for a keyseat groove of shaft parts, in particular to a clamp special for a keyseat groove of shaft parts, which solves the problems of complicated process, inaccurate positioning and low processing efficiency of the existing clamp. The clamp special for the keyseat groove of shaft parts comprises a base, V-shaped blocks are fixed on two sides of the base, a clamping device and a top tip on the base are arranged between the two V-shaped blocks, the clamping device comprises hook-shaped pressing plates which are distributed left and right, and an included angle being 60 degrees is formed between a contact point of the inner side at the upper part of the hook-shaped pressing plate and the shaft parts, and the horizontal plane as well as between the plane on which the axis of the shaft part is arranged and the horizontal plane. In the utility model, the pressing force angle of the hook-shaped pressing plates is changed, so that the clamping force of the hook-shaped pressing plate in the middle is enlarged, simultaneously, an arc-shaped pressing plate at the small end is removed, the inaccurate positioning caused by the two pressing plates can be alleviated, the operation complexity is lowered and the processing efficiency is improved.

Description

Axial workpiece keyseat special fixture
Technical field
The utility model relates to axial workpiece keyseat servicing unit, is specially a kind of axial workpiece keyseat special fixture.
Background technology
During the axial workpiece keyseat, existing anchor clamps adopt two place's clamp mechanism, and the small end cylindrical is used arc pressuring plate; Hook-shaped pressing plate is used in the centre, though two places all are automatic centering clamping mechanism, because rigging error; Can cause to clamp and retrodeviate decentre; Cause the location inaccurate, processing back position error is unstable, and operation is comparatively loaded down with trivial details during clamping workpiece.
Summary of the invention
The utility model exists complex operation, the location is inaccurate and working (machining) efficiency is low problem in order to solve existing anchor clamps, and a kind of axial workpiece keyseat special fixture is provided.
The utility model is to adopt following technical scheme to realize: axial workpiece keyseat special fixture; Comprise base; The left and right sides of base all is fixed with V-block; Be provided with the clamping device that is located on the base and top between two V-blocks, two that distribute about clamping device comprises are colluded the type pressing plate, collude the point of contact of type pressing plate upper inner and axial workpiece and spend angles with the plane that the axial workpiece axis belongs to horizontal by 60.Collude the angle of type pressing plate upper inner and axial workpiece through change, can self-centering, remove the small end arc pressuring plate simultaneously, overcome existing anchor clamps and had complex operation, the location is inaccurate and working (machining) efficiency is low problem.
The utility model is through the pressure angle of the hook-shaped pressing plate of change, and hook-shaped pressing plate clamping force in the middle of increasing is removed the small end arc pressuring plate simultaneously, reduces the inaccurate problem in location that two place's pressing plates cause, and has reduced complex operation property, has improved working (machining) efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-base, 2-V type piece, 3-is top, and 4-colludes the type pressing plate, the 5-axial workpiece.
The specific embodiment
Axial workpiece keyseat special fixture; Comprise base 1; The left and right sides of base 1 all is fixed with V-block 2; Be provided with the clamping device that is located on the base 1 and top 3 between two V-blocks 2, two that distribute about clamping device comprises are colluded type pressing plate 4, collude the point of contact of type pressing plate 4 upper inner and axial workpiece 5 and spend angles with the plane that axial workpiece 5 axis belong to horizontal by 60.
