Abstract
The invention relates to a fixture for processing large and small head holes of a connecting rod. The fixture comprises a right-angle locating block, a plane locating block, fastening screws, locating screws, an adjusting nut and a compression bolt, wherein the right-angle locating block and the plane locating block are fixed on a perforated mold plate by the fastening screws; the locating screws are contacted with a small connecting rod head locating point and a large connecting rod head bolt face respectively by the right-angle locating block and the plane locating block; the adjusting nut is arranged on the right-angle locating block, and corresponds to a small connecting rod end leftwards; and the compression bolt is fixed on the perforated mold plate and corresponds to a large connecting rod end. According to the fixture, a locating reference is transferred to two locating points from the small head hole, a fit clearance error is avoided, a center distance of the connecting rod and location degrees of the large and small holes of the connecting rod are not influenced by the variation of the small head hole, and the fixture has the characteristics of simple structure, convenience, practicality, time and labor saving and the like.
Description
Technical field
The present invention relates to the engine link manufacture field, is a kind of fixture of processing connecting rod concentric reducer hole specifically.
Background technology
We know, at present when the concentric reducer hole of processing engine link, the fixture and the positioning datum that adopt have a variety of, more commonly adopting the microcephaly hole is positioning datum processing connecting rod, yet 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 in concentric reducer hole.Simultaneously, the method clamping trouble, time-consuming, and be easy to connecting rod is produced secondary damage.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned existing fixture, provides a kind of take the small end of connecting rod anchor point as benchmark, the fixture in the processing connecting rod concentric reducer hole of convenient mounting and clamping, time saving and energy saving, accurate positioning.
the present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of fixture of processing connecting rod concentric reducer hole, be provided with tire plate with holes, the right angle locating piece, the plane positioning piece, 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 contacts with the small end of connecting rod anchor point by the right angle locating piece, another dog screw contacts with the connecting-rod bolts face by the plane positioning piece, also be provided with adjusting nut on the right angle locating piece, 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, locate not only convenient mounting and clamping with microcephaly's anchor point, and avoided the mismatch error of connecting rod small end hole and location mandril in the past, simultaneously can be because of the variable effect connecting rod centre-to-centre spacing in microcephaly hole and the position degree of the large aperture of connecting rod, have the advantages such as time saving and energy saving, accurate positioning.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after clamping connecting rod of the present invention.
Be labeled as 1. tire plates with holes in figure, 2. right angle locating piece, 3. plane positioning piece, 4. trip bolt, 5. dog screw, 6. adjusting nut, 7. hold-down bolt, 8. connecting rod.
The specific embodiment
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 of processing connecting rod concentric reducer hole, be provided with tire plate 1 with holes, right angle locating piece 2, plane positioning piece 3, trip bolt 4, dog screw 5, adjusting nut 6, hold-down bolt 7, connecting rod 8, locating piece 2 use trip bolts 4 in right angle are fixed on tire plate 1 with holes, plane positioning piece 3 use fastening bolts 4 are fixed on tire plate 1 with holes, dog screw 5 screws in right angle locating piece 2 and plane locating piece 3, contacts with small end of connecting rod anchor point and connecting-rod bolts face respectively.Adjusting nut 6 screws in right angle locating piece 2, with hold-down bolt 7, engine link 8 is fixed and clamped.
When the present invention used, operating personnel can adjust bolt length according to the kind needs.The positioning datum that the present invention will process connecting rod is transferred on two anchor points by the microcephaly hole, locate not only convenient mounting and clamping with microcephaly's anchor point, and do not have the fit clearance error, simultaneously can be because of variable effect connecting rod centre-to-centre spacing and the connecting rod size hole location in microcephaly hole.
