Abstract
The invention relates to a fixture for machining a joint surface of an engine connecting rod. The fixture comprises a fixture bed mold, a bolt surface positioning block, fastening bolts, a large-end semicircular flat gasket, a bolt surface side clamping screw, a small-end circular flat gasket, clamping screw positioning blocks, a right-angle positioning block, and a small-end side clamping screw, and is characterized in that the semicircular flat gasket on the fixture bed mold is as thick as the circular flat gasket; the bolt surface positioning block, the clamping screw positioning blocks and the right-angle positioning block are fixed on the fixture bed mold according to positions of the connecting rod via the fastening bolts; the bolt surface side clamping screw and the small-end side clamping screw are in threaded connection with the clamping screw positioning blocks; a connecting rod workpiece is fixed via a clamping bolt. The fixture has the advantages that a small end being the positioning basis of machining of the connecting rod is replaced by two positioning points, and small end positioning ends are used for positioning, so that not only is the clamping convenient, but also fit clearance error is avoided, and impact of change of a small end hole on the center distance of the connecting rod and the location degrees of a large hole and a small hole in the connecting rod can be avoided; the structure is simple; the use is convenient and practical; time and labor are saved.
Description
Technical field
The present invention relates to a kind of engine link clamp for machining, is the fixture of a kind of engine link processing faying face specifically.
Background technology
We know, current engine link processing adopts little head bore positioning datum to have a variety of, little head bore is more commonly adopted to be positioning datum processing connecting rod, but utilize connecting rod small end hole to locate the mismatch error easily producing little head bore and location mandril, have a strong impact on the centre-to-centre spacing of connecting rod and the position degree of size head bore.The method clamping trouble is time-consuming simultaneously, and is easy to produce secondary damage to connecting rod.
Summary of the invention
Technical problem to be solved by this invention is the deficiency overcoming above-mentioned existing fixture, provides a kind of small end of connecting rod anchor point to be the fixture that benchmark carries out processing joint surface of connection rod.
The present invention's taked technical scheme that solves the problem is: a kind of engine link processing faying face fixture, be provided with fixture tire plate, bolt face locating piece, trip bolt, major part semicircle plain cushion, bolt face pinching screw, the circular plain cushion of microcephaly, pinching screw locating piece, right angle locating piece, microcephaly's pinching screw, it is characterized in that: fixture tire plate is provided with major part semicircle plain cushion and the circular plain cushion of microcephaly, both tops place major part and the microcephaly of connecting rod respectively, and plain cushion thickness is identical, the side of major part semicircle plain cushion is provided with bolt face locating piece, and fix with trip bolt, opposite side is provided with bolt face pinching screw, the circular plain cushion side of microcephaly is provided with right angle locating piece, opposite side is provided with microcephaly's pinching screw, bolt face pinching screw and microcephaly's pinching screw are installed on pinching screw locating piece, pinching screw locating piece, right angle locating piece is also all fixed on fixture tire plate with trip bolt.
The present invention, owing to adopting technique scheme, solves workpiece multiple clamping troublesome poeration, workpiece accuracy and ropy problem, rise easy to operate, and time processing goes out multiple workpiece, its benchmark is all unified, improve working (machining) efficiency, ensure that precision and the quality of workpiece simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the structural representations after clamping workpiece of the present invention.
Be labeled as in figure: 1. fixture tire plate, 2. bolt face locating piece, 3. trip bolt, 4. major part semicircle plain cushion, 5. bolt face pinching screw, 6. microcephaly's circular plain cushion, 7. pinching screw locating piece, 8. right angle locating piece, 9. microcephaly's pinching screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As accompanying drawing 1, shown in accompanying drawing 2, the present invention relates to a kind of engine link processing faying face fixture, be provided with fixture tire plate 1, bolt face locating piece 2, trip bolt 3, major part semicircle plain cushion 4, bolt face pinching screw 5, the circular plain cushion 6 of microcephaly, pinching screw locating piece 7, right angle locating piece 8, microcephaly's pinching screw 9, it is characterized in that: fixture tire plate 1 is provided with major part semicircle plain cushion 4 and the circular plain cushion 6 of microcephaly, both tops place major part and the microcephaly of connecting rod respectively, and plain cushion thickness is identical, the side of major part semicircle plain cushion 4 is provided with bolt face locating piece 2, and fix with trip bolt 3, opposite side is provided with bolt face pinching screw 5, circular plain cushion 6 side of microcephaly is provided with right angle locating piece 8, opposite side is provided with microcephaly's pinching screw 9, bolt face pinching screw 5 and microcephaly's pinching screw 9 are installed on pinching screw locating piece 7, pinching screw locating piece 7, right angle locating piece 8 is also all fixed on fixture tire plate 1 with trip bolt 3.
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.Structure is simple, convenient and practical, time saving and energy saving.
