Abstract
The utility model relates to a crankshaft flat laying holding device, which comprises a plurality groups of double-linked V-shaped blocks, an upward acting plate, a pressing screw rod and nuts, wherein the double-linked V-shaped blocks are fixed on a vibration baseplate through screws, and are provided with two V-shaped grooves arranged in parallel, and a screw hole is formed between the two V-shaped grooves; the lower end of the pressing screw rod is fixed in the screw hole of the double-linked V-shaped blocks, and the other end thereof is inserted in an unthreaded hole of the upward acting plate, is matched with nuts at the top of the upward acting plate, connected with the upward acting plate through nuts, and tightly clamped on a crankshaft clamped between the double-linked V-shaped blocks and the upward acting plate. The crankshaft flat laying holding device has the advantages of simple and reasonable structure, and can clamp and fix two ageing shafts at a time, the number of the ageing shafts at a time is increased, the number of holding-down bolts is reduced, the operation and use are convenient, the labor intensity of operators is reduced, the working efficiency is high, and the crankshaft flat laying holding device is suitable for the use of clamping and fixing shaft parts during vibration and aging operations.
Description
Technical field
The utility model relates to a kind of clamping device, specifically a kind of bent axle tiling clamping device.Fixing use when it is suitable for axial workpiece and carries out oscillating aging.
Background technology
We know, in the axial workpiece manufacturing processed, since stressed or be heated inhomogeneously, innerly produce uneven plastic deformation, after processing, all there is unrelieved stress.Unrelieved stress is the major reason of hardware cracking or distortion, greatly influences the fatigue strength of hardware and the stability of dimensional precision.Eliminating unrelieved stress is crucial task of mechanical processing industry.Oscillating aging (VSR) be exactly by apply that method for oscillating reduces or the homogenizing member in unrelieved 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 in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and the timeliness axle that is fixedly clamped is placed in tiling, operation, easy to use, the bent axle tiling clamping device of high efficiency.
The technical scheme in the invention for solving the above technical problem is: a kind of bent axle tiling clamping device, it is characterized in that: it includes some groups of duplex V-blocks, top board, clamping screw, nut, the duplex V-block is screwed respectively on vibrating bottom plate, the duplex V-block is provided with two V-type grooves side by side, the centre of two V-type grooves is provided with a screw, the lower end of clamping screw is fixed in the screw of duplex V-block, the other end is inserted in the unthreaded hole of top board, cooperate with the nut that is arranged on top board top, connect top board, the bent axle of pressing clip between duplex V-block and top board by nut.
The said top board of the utility model is rectangle, and covers duplex V-block top, and length is greater than the distance between two V-type grooves of duplex V-block.
During the utility model work, two to five groups of duplex V-blocks are separately fixed on the vibrating bottom plate, two bent axle tilings are placed, and are clamped in respectively between duplex V-block and the top board, finish fixing by the timeliness axle.Against existing technologies, the utility model is simple and reasonable for structure, two timeliness axles once can be fixedly clamped, increase the quantity of the axle of a timeliness, reduced push bolt quantity, operation, easy to use, alleviated operator's labour intensity, high efficiency is suitable for axial workpiece, and clamping was used when particularly bent axle carried out oscillating aging.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model duplex V-block and top board connection diagram.
Label among the figure is: 1. duplex V-block, 2. top board, 3. clamping screw, 4. nut, 5. screw, 6. vibrating bottom plate, 7. bent axle.
Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of bent axle tiling clamping device, it includes some groups of duplex V-blocks 1, top board 2, clamping screw 3, nut 4 etc.Several duplex V-blocks 1 are screwed respectively on vibrating bottom plate 6.Said duplex V-block 1 is laterally to process left and right two V-type grooves on the part side by side, is provided with a screw in the mid-way of two V-type grooves.Said clamping screw 3 is the threaded studs in two ends, and the lower end of clamping screw 3 is tightened on the screw of duplex V-block 1, and the other end is inserted in the unthreaded hole of top board 2.Cooperate with the nut 4 that is arranged on top board 2 tops, connect top board 2, the bent axle of pressing clip between duplex V-block 1 and top board 2 by nut.
The said top board 2 of the utility model is rectangle, and covers duplex V-block 1 top, and length is greater than the distance between two V-type grooves of duplex V-block.That is to say that its length should surpass the center of two V-type grooves of duplex V-block 1 respectively to both sides from the centre.Top board 2 compresses downwards by the bent axle diameter of axle of timeliness axle by the nut 4 that is screwed in clamping screw 3 tops.
During the utility model work, as shown in Figure 1, three groups of duplex V-blocks, 1 usefulness screw 5 is fixed on the vibrating bottom plate 6.7 tilings of two velamen timeliness bent axles are placed, and are clamped between three groups of duplex V-blocks 1 and the top board 2, tighten three nuts 4 then, and the bent axle of pressing clip between duplex V-block and top board finished fixing by the timeliness axle.Two the timeliness axles that once can be fixedly clamped increase the quantity of the axle of a timeliness, have reduced push bolt quantity, and operation, easy to use has alleviated operator's labour intensity, high efficiency.
