Abstract
The utility model provides a general power engine crankshaft rod portion car machining fixture and aims to solve the problems that a general power engine crankshaft rod portion car machining fixture in the prior art is relatively complex in machining processes, long in machining time, high in cost, wasted in labor, low in production efficiency, bad in accuracy of clamping and positioning due to the fact the clamping directions of a crankshaft can be adjusted and changed every time when one end needs machining. The fixture comprises a tailstock centre and a floating centre, axes of the tailstock centre and the floating centre are symmetrically arranged on the same straight line. The general power engine crankshaft rod portion car machining fixture simplifies machining processes, shortens machining time, has no need to adjust and change the clamping directions of the crankshaft, saves labor forces, improves production efficiency, and achieves relatively high positioning accuracy.
Description
Technical field
The utility model relates to a kind of workpiece machining clamp, particularly a kind of general power machine crank shaft bar section workpiece machining clamp.
Background technology
In the prior art, general power machine crank shaft bar section workpiece machining clamp adopts the mode on a folder one top that bent axle is fixed usually, a so-called folder one top is that bent axle one end carries out clamping by scroll chuck, the other end holds out against by tailstock center, this mode no doubt can be firm fixed crankshaft, yet, the position of scroll chuck clamping bent axle is crank rod section, so bent axle can't directly be processed by the bar section of scroll chuck clamping one end, can only process first tailstock center and hold out against the crank rod section of an end, to be processed complete after, by manpower crank rod section transposing direction is carried out the Vehicle Processing of bent axle other end bar section again; Simultaneously, use scroll chuck clamping bent axle in the prior art, not only cost is higher, and positioning accuracy is relatively poor, so, to exist manufacturing procedure comparatively loaded down with trivial details for general power machine crank shaft bar section workpiece machining clamp in the prior art, and process time is longer, and cost is higher, every processing one end need to be changed bent axle clamping direction, labor intensive, production efficiency is lower, the problem of clamping position low precision.
Summary of the invention
To exist manufacturing procedure comparatively loaded down with trivial details in order to solve in the prior art general power machine crank shaft bar section workpiece machining clamp, process time is longer, cost is higher, every processing one end need to be changed bent axle clamping direction, labor intensive, production efficiency is lower, and the problem of clamping position low precision the utility model proposes a kind of general power machine crank shaft bar section workpiece machining clamp.General power machine crank shaft bar of the present utility model section workpiece machining clamp comprises tailstock center and unsteady thimble, and the axis of described tailstock center and unsteady thimble is symmetrical arranged at same straight line.
Further, described unsteady thimble comprises sleeve, base, spring, thimble and cushion cover, and described base is fixedly linked in the sleeve tail end, and described spring and thimble all are arranged in the sleeve, described spring places between base and the thimble, and described cushion cover is arranged between thimble and the sleeve.
The beneficial effect of general power machine crank shaft bar of the present utility model section workpiece machining clamp is: use general power machine crank shaft bar of the present utility model section workpiece machining clamp to simplify manufacturing procedure, shortened process time, need not to change bent axle clamping direction, saved the labour, improve production efficiency, and obtained higher positioning accuracy.

The specific embodiment
Fig. 1 is general power machine crank shaft bar of the prior art section workpiece machining clamp structural representation; 1 is tailstock center, 2 is scroll chuck, 3 is bent axle, as seen from the figure, in the prior art, general power machine crank shaft bar section workpiece machining clamp adopts the mode on a folder one top that bent axle 3 is fixed usually, a so-called folder one top is that bent axle 3 one ends carry out clamping by scroll chuck 2, the other end holds out against by tailstock center 1, this mode no doubt can be firm fixed crankshaft 3, yet, the position of scroll chuck 2 clamping bent axles 3 is crank rod section, so bent axle 3 can't directly be processed by an end crank rod section of scroll chuck 2 clampings, can only process first the crank rod section that tailstock center 1 holds out against an end, to be processed complete after, by manpower crank rod section transposing direction is carried out the Vehicle Processing of bent axle 3 other end bar sections again; Simultaneously, use scroll chuck 2 clamping bent axles 3 in the prior art, not only cost is higher, and positioning accuracy is relatively poor, so, to exist manufacturing procedure comparatively loaded down with trivial details for general power machine crank shaft bar section workpiece machining clamp in the prior art, and process time is longer, and cost is higher, every processing one end need to be changed bent axle 3 clamping directions, labor intensive, production efficiency is lower, the problem of clamping position low precision.
Fig. 2 is general power machine crank shaft bar of the present utility model section workpiece machining clamp structural representation; 1 is tailstock center, and 3 is bent axle, and 4 are the thimble that floats, and as seen from the figure, the general power machine crank shaft bar section workpiece machining clamp of utility model comprises tailstock center 1 and unsteady thimble 4, and the axis of described tailstock center 1 and unsteady thimble 4 is symmetrical arranged at same straight line.General power machine crank shaft bar of the present utility model section workpiece machining clamp only need get final product to unsteady thimble 4 directions compression bent axle 3 by tailstock center 1, need not again the scroll chuck clamping, simplified manufacturing procedure, shortened process time, simultaneously, general power machine crank shaft bar of the present utility model section workpiece machining clamp is by float thimble 4 and tailstock center 1 fixed crankshaft 3 that matches, unsteady thimble 4 and tailstock center 1 all hold out against bent axle 3 two ends centre bores, clamping bent axle 3 any end bar sections not, therefore bent axle 3 can be finished the Vehicle Processing of bent axle 3 two ends bar sections behind clamped one time, need not to change bent axle 3 clamping directions, saved the labour, improve production efficiency, obtained higher positioning accuracy.
Fig. 3 is unsteady thimble structure schematic diagram of the present utility model; 4-1 is sleeve, 4-2 is base, 4-3 is spring, and 4-4 is thimble, and 4-5 is cushion cover, as seen from the figure, unsteady thimble comprises sleeve 4-1, base 4-2, spring 4-3, thimble 4-4 and cushion cover 4-5, and described base 4-2 is fixedly linked in sleeve 4-1 tail end, and described spring 4-3 and thimble 4-4 all are arranged in the sleeve 4-1, described spring 4-3 is arranged between base 4-2 and the thimble 4-4, and described cushion cover 4-5 is arranged between thimble 4-4 and the sleeve 4-1.The thimble that should float can bear the larger thrust of tailstock center, and simple in structure, is easy to make.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
