Abstract
The invention relates to a workpiece holding device, in particular to a holding device for high-precision double-side processing of an axial workpiece; a locating bar is arranged on a bottom plate for axial location of a workpiece, the bottom plate and an upper pressure plate are connected by a bolt, the workpiece is arranged between the bottom plate and the upper pressure plate, the bolt on the upper pressure plate is screwed down, so as to the workpiece to have no gap between the upper pressure plate and the bottom plate, a workpiece side pushing block is arranged at one side of the bottom plate and is connected with a side pushing block screw rod, the workpiece side pushing block is screwed down to lead the two workpieces to be tightly pressed mutually, a part that the workpiece is extended out of the upper pressure plate is clamped by an upper clamping plate and a lower clamping plate, and the upper clamping plate and the lower clamping plate are connected by a clamping bolt. In the invention, the upper clamping plate and the lower clamping plate are used for clamping the workpiece and are an integrative component, when in turning, the integrative component is turned for 180 degrees, and the holding device is not turned for 180 degrees, that is, the workpiece body is turned about 180 degrees, the upper clamping plate and the lower clamping plate are light, therefore, the turning is very easy and the disadvantages of the common processing method are avoided, and the processing precision of the workpiece is ensured.
Description
Technical field
The invention belongs to the clamping device of the two flat processing of shaft-like workpiece high accuracy.
Background technology
Along with developing of automobile industry, require the quality of auto parts and components, precision also more and more higher.The automobile engine oil feed pump is the core component of automobile oil supply system, and fuel feeding pump shaft (see figure 1) is one of vital part of engine oil pump.The usual method of flat processing of fuel feeding pump shaft is (seeing Fig. 2,3):
1 work holder is placed on the workbench of surface grinding machine;
2 workpiece install to the good workpiece of clamping in the clamping device;
3 rely on emery wheel with workpiece, and it is flat to carry out one of grinding;
4 integral body are 180 ° of clamping device upsets, reprocess that another is flat;
Processing work does not reach the specification requirement of workpiece at all like this, and its reason is as follows:
1 since behind the precision of clamping device itself and the clamping workpiece center height of each workpiece variant, after 180 ° of the whole upsets of clamping device, the workpiece centre height workpiece centre height preceding with not having upset is not difficult to be controlled at below the 0.02mm tolerance;
The base plate of 2 clamping devices and top board and workbench contact area are bigger, and during each turning and clamping device, if base plate, top board and work top cleaning are unclean, even a little abrasive dust all can have very big influence to the machining accuracy of workpiece.
3 clamping devices are heavier, the effort when operator overturns, and labour intensity is big, and efficient is low.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, the clamping device of the two flat processing of a kind of shaft-like workpiece high accuracy is provided, realize the two flat processing of shaft-like workpiece high accuracy, simple in structure, upset is convenient, reduces labour intensity.
The technical scheme that the present invention is adopted for achieving the above object is: the clamping device of the two flat processing of shaft-like workpiece high accuracy, positioning strip is housed on the base plate, as the workpiece axial location, base plate is connected with bolt with top board, workpiece places between base plate and the top board, tighten the top board bolt, make workpiece very close to each other between top board and base plate, a side is equipped with the workpiece side pushing block on the base plate, and the workpiece side pushing block connects thruster piece screw rod, tightens the workpiece side pushing block, workpiece and workpiece are compressed mutually, workpiece stretches out the part of top board, clamps with train wheel bridge and lower plate, and train wheel bridge is connected by pinching screw with lower plate.
The present invention compares with existing clamping device, has outstanding feature, and it is the assembly of one by the upper and lower plates holding workpiece, and one assembly upset is 180 ° during upset, rather than 180 ° of turning and clamping devices.This is equivalent to 180 ° of workpiece upsets itself, and the train wheel bridge and the lower plate of workpiece are lighter, so upset is very easy to, has also avoided the drawback of common processing method simultaneously, has guaranteed the machining accuracy of workpiece.The present invention has avoided existing in the common processing method can't reach the technical problem of the two flat requirement on machining accuracy of high accuracy, and provide reasonable in design, compact conformation, labour intensity is little, flexible work holder, good product quality, production efficiency height have satisfied the specification requirement of the flat portion of workpiece high accuracy.
Four, description of drawings:
Fig. 1 is oil feed pump axle construction schematic diagram.
Fig. 2 is traditional clamping device structural representation.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is structural representation of the present invention.
Fig. 5 is the side view of Fig. 4.
Five, the specific embodiment:
As Fig. 4, the clamping device of the two flat processing of the shaft-like workpiece high accuracy shown in 5, on the base plate 2 of workbench 4 positioning strip 3 is housed, axial location as workpiece 7, base plate 2 is connected with top board 1 usefulness bolt, workpiece places between base plate and the top board, tighten the top board bolt, make workpiece 7 very close to each other between top board 1 and base plate 2, a side is equipped with workpiece side pushing block 5 on the base plate 1, workpiece side pushing block 5 connects thruster piece screw rod 6, tighten workpiece side pushing block 5, workpiece and workpiece are compressed mutually, and workpiece front end extension contacts with emery wheel 8 and processes, and the part of top board is stretched out in the workpiece rear end, clamp train wheel bridge and the tabular clamping plate of lower plate for being connected by pinching screw with train wheel bridge 9 and lower plate 10.
Adopt clamping device of the present invention, the process of workpiece is as follows:
1) workpiece is placed on the lower shoe, and relies on workpiece spindle to positioning strip;
2) press top board, adjust the top board screw and give workpiece suitable pretightning force;
3) rotating side pushing block lead-screw makes the thruster piece promote workpiece and closely arranges to a side;
4) adjust train wheel bridge and lower plate screw, train wheel bridge and lower plate be clipped on the workpiece.
5) clamping workpiece good after, one of grinding is flat;
6) after grinding well, unclamp the top board pinching screw;
7) upset is 180 ° of the assemblies of one by train wheel bridge and lower plate holding workpiece;
8) make the work end head rest to workpiece spindle to positioning strip, clamp top board, another is flat in grinding.
