Abstract

The utility model discloses a novel clamp for a finely ground camshaft, which comprises a lump clamp body; a camshaft hole is formed in the clamp body; lateral stepped holes are formed in the clamp body on the left side and the right side of the camshaft hole; locking positioning blocks are arranged in middle large-aperture sections of the lateral stepped holes; vertical parts of the locking positioning blocks are positioned in the middle large-aperture sections of the lateral stepped holes; lateral parts of the locking positioning blocks extend into the camshaft hole from the inner side small-aperture sections of the lateral stepped holes; the end surfaces of the lateral parts of the locking positioning blocks are arc-shaped concave surfaces; lock screws are inserted in the lateral stepped holes from the outer side; a vertical groove communicated with the camshaft hole is formed in the upper surface of the clamp body on the lower side of the camshaft hole; a positioning block is mounted in the vertical groove; the upper end of the positioning block extends into the camshaft hole; a lateral screw countersink is formed in the clamp body beside the vertical groove; a lateral lock screw is inserted into the lateral screw countersink to lock the positioning block. The novel clamp for the finely ground camshaft is reasonable in design, and easy to implement, and reduces the run-out of a camshaft base circle, and the rejection rate.

Description

Novel fine grinding camshaft fixture
Technical field
The utility model relates to special fixture, specifically, is a kind of novel fine grinding camshaft fixture.
Background technology
Camshaft is generally widely used in various products and realizes the reciprocating conversion that rotatablely moves, and cam axial workpiece is also typical structure part in machining, as camshaft of car engine, air-conditioner camshaft etc.Due to the rotary surface processing on the non-rotating part of being processed as of camshaft, need to locate by fixture, the general centre bore that adopts locates machining cam at present, cam base circle is beated and can be subject to the impact of centre bore, easily rotate, can produce error, this is just far beyond a lot of user's requirements.Camshaft journal is after grinding machine processing, and when grinding cam, cam base circle is beated also very serious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel fine grinding camshaft fixture, avoids rotating, and reduces scrappage.
The technical solution of the utility model is as follows: a kind of novel fine grinding camshaft fixture, comprise block clamp body (1), the upper through-thickness of described clamp body (1) is provided with camshaft hole (1a), it is characterized in that: described camshaft hole (1a) left side, the clamp body (1) on right side is provided with lateral step hole, described lateral step hole is by small-bore, outside screw section, aperture broad in the middle section and small-bore, inner side section composition, in the aperture broad in the middle section in described lateral step hole, locking positioning piece (3) is housed, described locking positioning piece (3) is inverted T shape, the vertical part of described locking positioning piece (3) is positioned at the aperture broad in the middle section in lateral step hole, the lateral part of described locking positioning piece (3) is stretched in camshaft hole (1a) from small-bore, the inner side section in lateral step hole, the end face of the lateral part of described locking positioning piece (3) is arc-shaped concave, lock screw (4) inserts in lateral step hole from outside, the upper surface of the clamp body (1) of described camshaft hole (1a) downside is provided with the vertical groove being communicated with camshaft hole (1a), locating piece (5) is housed in this vertical groove, camshaft hole (1a) is stretched in described locating piece (5) upper end, the other clamp body (1) of described vertical groove is provided with horizontal screw hole, laterally lock screw (6) inserts in horizontal screw hole locating piece (5) is locked.
Adopt technique scheme, cam sleeve, in camshaft hole, now, should be unscrewed horizontal lock screw, after cam sleeve is in camshaft hole, by locating piece upwards, make the end face laminating of locating piece top and camshaft, then tighten lock screw.Again lock screw is tightened, allowed the arc-shaped concave of locking positioning piece and the outer surface of camshaft fit, camshaft is compressed, avoid beating, avoid rotating.
In technique scheme: the lower end of described clamp body (1) is provided with horizontal adjusting bolt via hole, set screw (2) is housed in this adjusting bolt via hole.Set screw is pushed against on the regulating block on grinding machine, regulates the distance of set screw to regulating block, from changing the machining angle of camshaft.
In technique scheme: described clamp body (1) comprises top rectangular block, the lower end of rectangular block connects circular cone, and the lower end of circular cone connects adjustable column, and described set screw (2) is positioned on the adjustable column of lower end.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, avoids rotating, and reduces camshaft basic circle and beats, and reduces scrappage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
