Abstract

The invention relates to a double-layer clamping device for a bent axle, comprising a lower V-shaped block, a left post, a right post, an upper V-shaped block and an upper beam, wherein the left and right posts are respectively fixed at two sides of the lower V-shaped block through screws; the upper V-shaped block is installed above the lower V-shaped block; and one end of the upper beam is hinged with the left post through a pin, and the other end of the upper beam is connected with a gland nut on an eyelet bolt hinged on the right post through the eyelet bolt; and a double-layer bent axle is compressed and clamped between the lower V-shaped block and the upper V-shaped block and between the upper V-shaped block and the upper beam. The double-layer clamping device is simple and reliable in structure, two aging axles are compressed and fixed once, the number of the aging axle with once aging is increased, the number of the compression bolts is reduced; and the operation and use are convenient, the labor intensity of an operator is alleviated, the work efficiency is high, and the device is suitable for clamping axle parts in vibration aging.

Description

The double-deck clamping device of bent axle

Technical field

The present invention relates to a kind of clamping device, the double-deck clamping device of specifically a kind of bent axle.Fixing use when it is suitable for axial workpiece and carries out oscillating aging.

Background technology

We know, in the axial workpiece manufacture process, since stressed or be heated inhomogeneously, innerly produce uneven plastic deformation, after processing, all there is residual stress.Residual stress is the major reason of hardware cracking or distortion, greatly influences the fatigue strength of hardware and the stability of dimensional accuracy.Eliminating residual stress is crucial task of mechanical processing industry.Oscillating aging (VSR) be exactly through apply that method for oscillating reduces or the homogenizing member in residual stress, thereby improve the working strength of member, reduce to be out of shape and the precision of stable dimensions.When carrying out oscillating aging in the past, axial workpiece is tiled on the vibrating bottom plate, and compresses with a plurality of bolts.Therefore, limited by vibrating bottom plate, the quantity of an oscillating aging is few big or smallly, and because will tighten a plurality of bolts, so labour intensity is also very big.

Summary of the invention

Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of simple and reasonable for structure, operation, easy to use, the double-deck fixedly timeliness axle of placing, the double-deck clamping device of the bent axle of high efficiency.

The technical scheme that the present invention solves the problems of the technologies described above employing is: the double-deck clamping device of a kind of bent axle; It includes down V-block, left column, right column, goes up V-block, entablature; It is characterized in that: left column, right column are screwed the both sides at following V-block respectively; Last V-block is installed in down the V-block top; Entablature one end is through pin and left column hinge, and the other end is connected with clamp nut on the eyelet bolt in the eyelet bolt on the right column by hinge, and pressing clip is descending between V-block and the last V-block and the double-deck bent axle between last V-type and the entablature.

The present invention is said to be provided with a V-type groove above the V-block down.

The said V-block upper and lower surface of going up of the present invention respectively is provided with a V-type groove.

The outside and the following V-block that the present invention is said to go up V-block makes progress has concavo-convex mating surface between the inboard of jut.

When the present invention works, V-block under two to five groups is fixed on the vibrating bottom plate.A bent axle is placed on down in the V-type groove of V-block; Installing V-block above the V-block down; Another root bent axle is placed in the V-type groove above the V-block; Like this, two bent axles divide and two-layerly are clamped under several groups between the V-block and last V-block and between last V-type and the entablature, accomplish fixing to by the timeliness bent axle.Against existing technologies, the present invention is simple and reasonable for structure, and two timeliness axles once can be fixedly clamped; Increase the quantity of the axle of a timeliness; Reduced hold-down bolt quantity, operation, easy to use has alleviated operator's labour intensity; High efficiency, clamping is used when being suitable for that axial workpiece carried out oscillating aging.

Description of drawings

Below in conjunction with accompanying drawing the present invention is done further description.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the A-A cutaway view of Fig. 1.

Label among the figure is: 1. descend V-block, and 2. screw, 3. left column, 4. pin, 5. entablature, 6. clamp nut, 7. eyelet bolt is 8. gone up V-block, 9. right column.

The specific embodiment

As can be seen from Figure 1, the double-deck clamping device of a kind of bent axle, it includes down V-block 1, left column 3, right column 9, goes up V-block 8, entablature 5 etc.Be provided with a V-type groove above the V-block 1 under said.Left column 3, right column 9 are fixed on down the both sides of V-block 1 respectively with screw 2.Last V-block 8 is installed in down V-block 1 top, and said V-block 1 upper and lower surface of going up respectively is provided with a V-type groove, the V-type groove below wherein corresponding the V-type groove above the V-block 1 down, a bent axle is clipped between them.V-type groove above the last V-block 1 is used for carrying another root bent axle.Said entablature 5 one ends are through pin 4 and left column 3 hinges; The other end is connected with clamp nut 6 on the eyelet bolt 7 in the eyelet bolt on the right column 97 by hinge, and pressing clip is down between V-block 1 and the last V-block 8 and the double-deck bent axle between last V-type 8 and the entablature 5.

The outside and the following V-block 1 that the present invention is said to go up V-block 8 makes progress has concavo-convex mating surface between the inboard of jut.As shown in Figure 2.Like this, can make things convenient for, install V-block 8 on the V-block 1 down reliably.

When the present invention works, V-block 1 under two to five groups is fixed on the vibrating bottom plate.A bent axle is placed on down in the V-type groove of V-block 1; Installing V-block 8 above the V-block down; Another root bent axle is placed in the V-type groove above the V-block 8; Like this, two bent axles divide and two-layerly are clamped under several groups between the V-block 1 and last V-block 8 and between last V-type 8 and the entablature 5, and reliable grip is fixing by the timeliness bent axle.The present invention is simple and reasonable for structure, two the timeliness axles that once can be fixedly clamped, and the quantity of the axle of a timeliness of increase has reduced hold-down bolt quantity, and operation, easy to use has alleviated operator's labour intensity, high efficiency.
