Abstract
The utility model discloses a clamp capable of preventing a camshaft from rotation during fine grinding. The clamp comprises a clamp body, wherein the clamp body comprises a locating block 1a; an adjusting pillar 1b is arranged at the upper end of the locating block 1a; left and right clamping parts 1c are arranged at the lower end of the locating block 1a; upper parts of the left and right clamping parts 1c are arc-shaped parts bulging outwards; the arc-shaped parts at the upper parts of the left and right clamping parts 1c are butted to form a camshaft hole; a transversal bolt through hole is formed in each of the lower parts of the left and right clamping parts 1c; a clamping bolt 2 penetrates through the bolt through holes in the left and right clamping parts 1c; a vertical locating plate 3 is arranged on the upper surface of the locating block 1a; the lower end of the vertical locating plate 3 extends to the front of the camshaft hole; a locating pin hole 3a is formed in the part, positioned in front of the camshaft hole, of the vertical locating plate 3; a transversal bolt through hole is formed in the adjusting pillar 1b; an adjusting screw 4 is inserted in the transversal bolt through hole of the adjusting pillar 1b. The clamp is reasonable in design, simple in structure and easy to implement, reduces the run-out of the base circle of the camshaft, and reduces the scrap rate.
Description
Technical field
The utility model relates to special fixture, specifically, is a kind of anti-rotation 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 anti-rotation fine grinding camshaft fixture, can avoid rotating, and reduces scrappage, convenient dress camshaft.
The technical solution of the utility model is as follows: a kind of anti-rotation fine grinding camshaft fixture, comprise clamp body, it is characterized in that: described clamp body comprises locating piece (1a), the upper end of described locating piece (1a) is provided with adjustable column (1b), the lower end of described locating piece (1a) is provided with a left side, right clamping section (1c), a described left side, the curved portions that the top of right clamping section (1c) is outwardly convex, a described left side, the top curved portions docking of right clamping section (1c) forms camshaft hole, a described left side, the bottom of right clamping section (1c) is equipped with and is provided with cross bolts via hole, fishbolt (2) is through left, the bolt through-hole of right clamping section (1c), the upper surface of described locating piece (1a) is provided with vertical location-plate (3), the lower end of described vertical location-plate (3) reaches camshaft hole front, the part that described vertical location-plate (3) is positioned at before camshaft hole is provided with dowel hole (3a), described adjustable column (1b) is provided with horizontal bolt through-hole, and set screw (4) is inserted in the cross bolts via hole of adjustable column (1b).
Adopt technique scheme, when dress camshaft, fishbolt is unclamped, camshaft is contained in camshaft hole, and then tightens fishbolt, camshaft is held tightly in clamping section, left and right.Now, the end face of camshaft is close to the end face of vertical locating piece, camshaft is provided with dowel hole, an alignment pin is through the dowel hole that inserts camshaft after the dowel hole that is arranged in the part before camshaft hole of vertical locating piece, camshaft is fixed on vertical locating piece, avoids camshaft to rotate.Set screw is pushed against on the regulating block on grinding machine, regulates the distance of set screw to regulating block, thereby changes the machining angle of camshaft.
In technique scheme: in order to ensure vertical locating piece fixation, described vertical locating piece (3) is fixed on the upper surface of locating piece (1a) by two alignment pins (5) and a screw (6).
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.
