Abstract
The invention relates to a clamp used in processing of a large end hole and a small end hole in a connecting rod. The clamp comprises a right-angle positioning block, a flat surface positioning block, fastening screws, positioning screws, an adjusting nut, a compression bolt and the like, wherein the right-angle positioning block and the flat surface positioning block are fixed to a bed mould with holes through the fastening screws; the positioning screws are in contact with a connecting rod small end positioning point and a connecting rod large end bolt surface through the right-angle positioning block and the flat surface positioning block respectively; the adjusting screw is also arranged on the right-angle positioning block, and corresponds to a small end of the connecting rod leftwards; the compression bolt is fixed to the bed mould with the holes, and corresponds to a large end of the connecting rod. A positioning reference is transferred to two positioning points from a small end, so that fit clearance errors can be avoided, and the change of the small end hole cannot affect the center distance of the connecting rod and the position tolerance between a large hole and a small hole of the connecting rod; the clamp has the characteristics of being simple in structure, convenient to use, and capable of saving time and labor.
Description
Technical field
The present invention relates to engine link manufacture field, is a kind of fixture processing connecting rod size head bore specifically.
Background technology
We know, at present when processing the size head bore of engine link, the fixture adopted and positioning datum have a variety of, little head bore is more commonly adopted to be positioning datum processing connecting rod, but easily produce mismatch error between connecting rod small end hole and location mandril, have a strong impact on the centre-to-centre spacing of connecting rod and the position degree of size head bore.Meanwhile, the method clamping trouble, time-consuming, and be easy to connecting rod produce secondary damage.
Summary of the invention
Technical problem to be solved by this invention is the deficiency overcoming above-mentioned existing fixture, provide a kind of with small end of connecting rod anchor point for benchmark, the fixture of the processing connecting rod size head bore of convenient mounting and clamping, time saving and energy saving, accurate positioning.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of fixture processing connecting rod size head bore, be provided with tire plate with holes, right angle locating piece, plane positioning block, trip bolt, dog screw, adjusting nut, hold-down bolt, connecting rod, it is characterized in that: right angle locating piece and plane locating piece are fixed on tire plate with holes by trip bolt, dog screw is contacted with small end of connecting rod anchor point by right angle locating piece, another dog screw is contacted with bolt surface of connection rod by plane positioning block, right angle locating piece is also provided with adjusting nut, adjusting nut is corresponding with the position of wrist-pin end of connecting rod left, hold-down bolt is fixed on the upper end of tire plate with holes, hold-down bolt is corresponding with the position of connecting rod tip downwards.
The present invention is owing to adopting said structure, not only convenient mounting and clamping is located with microcephaly's anchor point, and avoid the mismatch error of connecting rod small end hole and location mandril in the past, simultaneously can not because of the position degree of the variable effect connecting rod centre-to-centre spacing of little head bore and the large aperture of connecting rod, there is the advantages such as time saving and energy saving, accurate positioning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after clamping connecting rod of the present invention.
1. tire plate with holes, 2. right angle locating piece, 3. plane positioning block, 4. trip bolt, 5. dog screw, 6. adjusting nut, 7. hold-down bolt, 8. connecting rods are labeled as in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1 and Figure 2, the present invention relates to a kind of fixture processing connecting rod size head bore, be provided with tire plate 1 with holes, right angle locating piece 2, plane positioning block 3, trip bolt 4, dog screw 5, adjusting nut 6, hold-down bolt 7, connecting rod 8, right angle locating piece 2 trip bolt 4 is fixed on tire plate 1 with holes, plane positioning block 3 fastening bolt 4 is fixed on tire plate 1 with holes, dog screw 5 screws in right angle locating piece 2 and plane locating piece 3, contacts respectively with small end of connecting rod anchor point and bolt surface of connection rod.Adjusting nut 6 screws in right angle locating piece 2, is fixed and clamped by engine link 8 with hold-down bolt 7.
When the present invention uses, operating personnel can need adjustment bolt length according to kind.The positioning datum of processing connecting rod is transferred on two anchor points by little head bore by the present invention, not only convenient mounting and clamping is located with microcephaly's anchor point, and there is not fit clearance error, simultaneously can not because of the variable effect connecting rod centre-to-centre spacing of little head bore and connecting rod size hole location.
