Abstract
The utility model discloses a fine grinding camshaft clamp. The fine grinding camshaft clamp comprises a lump clamp body, wherein a camshaft hole is formed in the clamp body; a vertical stepped hole is formed in the clamp body on the upper side of the camshaft hole; a T-shaped locking positioning block is mounted in the middle large aperture section of the vertical stepped hole; the transversal section of the locking positioning block is positioned in the middle large aperture section of the vertical stepped hole; the vertical part of the locking positioning block extends into the camshaft hole from a lower part small aperture section of the vertical stepped hole; the lower end surface of the positioning block is an arc-shaped concave surface; a locking screw is inserted into the vertical stepped hole; 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 horizontal screw counter bored hole is formed in the clamp body beside the vertical groove; the horizontal locking screw is inserted into the horizontal screw counter bored hole to lock the positioning block. The fine grinding camshaft clamp is reasonable in design, simple in structure and easy to implement, reduces the possibility of the base circle run-out of a camshaft, and reduces the scrappage.
Description
Technical field
The utility model relates to special fixture, specifically, is a kind of 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 axle at present, camshaft basic 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 fine grinding camshaft fixture, can be good at avoiding rotating, and reduces scrappage.
The technical solution of the utility model is as follows: a kind of 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: the clamp body (1) of described camshaft hole (1a) upside is provided with vertical stepped hole, described vertical stepped hole is by small-bore, top screw section, aperture broad in the middle section and small-bore, bottom section composition, in the aperture broad in the middle section of described vertical stepped hole, locking positioning piece (3) is housed, described locking positioning piece (3) is T-shaped, the lateral part of described locking positioning piece (3) is positioned at the aperture broad in the middle section of vertical stepped hole, the vertical part of described locking positioning piece (3) stretches in camshaft hole (1a) from small-bore, the bottom section of vertical stepped hole, the lower surface of described locking positioning piece (3) is arc-shaped concave, lock screw (4) inserts in vertical stepped hole from upper end, 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, described locating piece (5) upper end reaches in camshaft hole (1a), 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 horizontal lock screw.Again lock screw is tightened downwards, allowed the arc-shaped concave of lower end of locking positioning piece and the outer surface of camshaft fit, camshaft is compressed, avoid rotating, reduce to beat.
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.
