Abstract
The utility model discloses a jig which is capable of controlling flatness and circularity, and comprises two ends clamping devices and a middle horizontal direction clamping device, each of the two ends clamping devices comprises a positioning oil cylinder and an axial positioning standard, the middle horizontal direction clamping device comprises a middle clamping oil cylinder and a multi-contact oil cylinder, the using process of the jig is characterized in that the two ends clamping devices are used for carrying out axial positioning, after the axial positioning, a swing arm rotates, falls and crushes, then carries out the clamping in horizontal direction by using the middle clamping oil cylinder and the multi-contact oil cylinder, not like that the prior art carries out clamping in the vertical direction, therefore the utility model has good control ability to the flatness of the end surface, and the circularity of the main reduction hole and the rear cover hole.
Description
Technical field
The utility model relates to the used anchor clamps of grip objects field, especially a kind ofly is suitable for the anchor clamps that the rear axle housing master subtracts the processing of hole and end face one thereof.
Background technology
Banjo type housing in the existing automobile, as the processing of EQ, CA series rear axle housing, domestic building-block machine and the special fixture of adopting mostly at present finished lathe: adopt bore hole face work unit head (generally to adopt two correct borings, another boring bonnet hole), face work behind the first bore hole; Anchor clamps: utilize two end flanges V-types location, above pressing plate compress, add two supplemental support below the axle housing centre, directly over auxiliary compressing.This technology is not high for the flatness of end face, the main circularity control ability that subtracts hole and bonnet hole, especially correct boring, and equipment is huge, operation inconvenience.
The utility model content
Technical assignment of the present utility model is at not enough in the above-mentioned technology, and the anchor clamps of a kind of energy control plane degree and circularity are provided.
The technical scheme that the utility model technical solution problem is adopted is: the anchor clamps of a kind of energy control plane degree and circularity, comprise two ends clamping device and by-level direction clamping device, described two ends clamping device comprises axial location oil cylinder and axial location benchmark, and described by-level direction clamping device comprises therebetween locking oil cylinder and multiconductor oil cylinder.Because the use of these anchor clamps is to utilize the two ends clamping device to carry out axial location earlier, treat axially to locate, the swing arm revolution, fall, after the pressing, successively utilize therebetween locking oil cylinder and multiconductor oil cylinder to carry out the clamping of horizontal direction again, but not clamp in vertical direction as prior art, so, finally control energy better for the flatness of end face, the main circularity that subtracts hole and bonnet hole.
Described multiconductor oil cylinder is three contact oil cylinders preferably, and for rough hair accessory surface, three contacts are difficult to touch simultaneously the surface of mao accessory, for make workpiece can be stressed under clamped condition evenly, reduce distortion,, be called for short three contact oil cylinders here so adopt the oil cylinder that three pistons are arranged.
The beneficial effect that the utility model can bring is:
1, better for the circularity control ratio of the flatness of end face, round piece.
Description of drawings
Accompanying drawing is a utility model and rear axle housing to be processed overall structure schematic diagram when combining;
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As shown in drawings, the utility model provides the anchor clamps of a kind of energy control plane degree and circularity, comprise two ends clamping device and by-level direction clamping device, described two ends clamping device comprises axial location oil cylinder 1 and axial location benchmark 2, and described by-level direction clamping device comprises therebetween locking oil cylinder 3 and multiconductor oil cylinder 4.
Described multiconductor oil cylinder 4 is three contact oil cylinders 4 preferably, for rough hair accessory surface, three contacts 5 are difficult to touch simultaneously the surface of mao accessory, for make workpiece can be stressed under clamped condition evenly, reduce distortion, so adopt the oil cylinder that three pistons are arranged, be called for short three contact oil cylinders 4 here.
During use, the operative employee hangs rear axle housing 12 on carriage 7, along guide rail 8 rear axle housing 12 is pushed on the operating position again, action is afterwards finished automatically by anchor clamps, at first 2 pairs of rear axle housings of axial location oil cylinder 1 and axial location benchmark 12 carry out axial location, V-type frame 6 clamps, swing arm revolution then, fall, after the pressing, successively utilize therebetween locking oil cylinder 3 and multiconductor oil cylinder 4 to carry out the clamping of horizontal direction again, but not clamp in vertical direction as prior art, so, finally control energy better for the flatness of end face 11, the main circularity that subtracts hole 9 and bonnet hole 10.
Claims (2)
1. the anchor clamps of energy control plane degree and circularity, it is characterized in that: comprise that device is stepped up at two ends and the by-level direction is stepped up device, described two ends are stepped up device and are comprised axial location oil cylinder and axial location benchmark, and described by-level direction is stepped up device and comprised middle add locking oil cylinder and multiconductor oil cylinder.
2. the anchor clamps of a kind of energy control plane degree according to claim 1 and circularity, it is characterized in that: described multiconductor oil cylinder is three contact oil cylinders.
