Abstract
The invention discloses a workpiece positioning device for a tailstock of a high-precision numerical control boring burnishing machine. The workpiece positioning device is an essential mechanical part of the novel high-precision numerical control boring burnishing machine. When workpiece is needed to be jacked tightly in the processing, a plunger cylinder is started, and a plunger drives a centering sleeve to jack two end surfaces of the workpiece, so that in the process of processing the workpiece, workpiece scrapping or cutter damage caused by the workpiece are prevented. The device is simple in structure, and accurate and convenient in positioning and clamping; axial movement of the workpiece in the boring process can be effectively prevented, so accidents of cutter damage or workpiece scrapping and the like caused by workpiece movement are effectively prevented; powerful guarantee is provided for ensuring the product quality and prolonging service life of the cutter; meanwhile, the cost is lowered and the enterprise benefit is improved.
Description
Technical field
The present invention relates to transformation, be specially a kind of Working piece positioning device of numerical control boring cleaning mill tailstock the boring cleaning mill.
Background technology
High-accuracy numerical control boring cleaning mill, adopt advanced in the world bore hole, the roll extrusion complex machining process, processing only need make a round trip, can finish cylinder barrel endoporus machining accuracy (IT8 level) and surface roughness and reach Ra0.2, this traditional diamond-making technique efficient improves 15-20 doubly, succeeding in developing of this equipment is the great-leap-forward raising of hydraulic cylinder process unit ability, it is once epoch-making revolution, be the old technology of alternate device, new thinking is provided, and this product embodies not only energy-conservation but also environmental protection, and market has very wide prospect at home.
Novel high-accuracy numerical control boring cleaning mill comprises tailstock, oil delivering unit, boring bar, headstock etc., the main effect of tailstock is that processing work can correctly be located fast, and workpiece held out against, make and have certain pretightning force between the workpiece two ends, guarantee in the boring process, not produce axial float at workpiece, effectively prevent because of workpiece moves accident such as cause that tool damage and workpiece are scrapped, and that existing processing and positioning device clamps, locatees is cumbersome, can not satisfies the requirement of modern production.Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, locate, clamp accurately, conveniently, can guarantee effectively that workpiece does not produce axial float in the boring process, effectively prevent to move because of workpiece the Working piece positioning device of the high-accuracy numerical control boring cleaning mill tailstock of accidents such as causing that tool damage and workpiece are scrapped.
For addressing the above problem, the present invention adopts following technology: a kind of Working piece positioning device of high-accuracy numerical control boring cleaning mill tailstock, comprise plunger case, plunger, end cap, centring sleeve, described plunger case is the second order tube structure and has oil-in, wherein the axial outer end face of an exponent part and tailstock pedestal are fixedly linked, the axial outer end face of two exponent parts is fixedlyed connected with end cap, described plunger is an annular workpieces, its outer circumference surface respectively with the tailstock pedestal, plunger case, the madial wall of end cap is tightly connected, also be provided with a bulge loop on the outer circumference surface of described plunger, corresponding plunger case two exponent parts of described bulge loop are installed and are linked to each other with the inner peripheral wall sealing of two exponent parts; The exposed junction of described plunger is provided with centring sleeve, and the import department of described centring sleeve forms cone structure.
As a further improvement on the present invention: the tapered structure of described centring sleeve entrance point.The big I of cone angle is changed according to the size of workpiece diameter, and highly versatile is easy to process.
The present invention is indispensable a kind of mechanical part on the novel high-accuracy numerical control boring cleaning mill, when workpiece processing need hold out against, start plunger case earlier, plunger just drives centring sleeve the workpiece biend is held out against, thereby guarantee workpiece in process, can be not former thereby cause workpiece to be scrapped or cause tool damage because of workpiece.The present invention is simple in structure, locate, clamp accurately, conveniently, can guarantee effectively that workpiece does not produce axial float in the boring process, effectively prevent to cause that tool damage and workpiece are scrapped etc. accident takes place because of workpiece moves, provide powerful guarantee cutter life to guaranteeing product quality and improving, to the increase performance of enterprises that reduces cost, play positive role simultaneously.
Description of drawings
Fig. 1 is the johning knot composition between tailstock in the numerical control boring cleaning mill and the oil delivering unit;
Fig. 2 is an A part enlarged drawing among Fig. 1.
Among the figure, 1 is workpiece; 2 is tailstock; 21 is the tailstock pedestal; 22 is plunger case; 221 is oil-in; 23 is plunger; 231 is bulge loop; 24 is centring sleeve; 25 is end cap; 3 for regulating supporting seat; 4 is oil delivering unit.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1 and Figure 2, numerical control boring cleaning mill comprises tailstock 2, regulates supporting seat 3 and oil delivering unit 4, and oil delivering unit 4 lower ends are installed on the guide rail, are installed with workpiece 1 between tailstock 2 and oil delivering unit 4.The Working piece positioning device that the present invention relates to is installed in tailstock 2 inside, and it comprises plunger case 22, plunger 23, end cap 25, centring sleeve 24, and described plunger case 22 is for having the second order tube structure of oil-in 221, and the internal diameter of an exponent part is less than the internal diameter of two exponent parts; Wherein the axial outer end face of an exponent part and tailstock pedestal 21 are weldingly connected, and the axial outer end face of two exponent parts is connected with end cap 25 bolting, and is provided with sealing strip between the two; Described plunger 23 is an annular workpieces, and its outer circumference surface is tightly connected with the inner peripheral wall of tailstock pedestal 21, plunger case 22, end cap 25 respectively; Two exponent parts of corresponding plunger case 22, be formed with a bulge loop 231 on the outer circumference surface of plunger 23, described bulge loop 231 slides between plunger case one exponent part and end cap 25 along the inwall of plunger case two exponent parts, and bulge loop 231 links to each other with the inner peripheral wall sealing of plunger case two exponent parts; Be connected to centring sleeve 24 in the right-hand member of plunger 23, described centring sleeve 24 is connected with plunger 23 bolting; The tapered structure of the entrance point of described centring sleeve 24.
When the present invention works, after workpiece 1 is put into tailstock 2 and oil delivering unit 4 centres, regulate supporting seat 3 and make Primary Location, start oil delivering unit 4 then workpiece 1 is sent to tailstock 2 ends, wherein workpiece 1 one ends enter in the taper hole of apparatus of the present invention centring sleeve 24, at this moment, oil delivering unit 4 lockings, oil delivering unit 4 is fixed on the guide pass, open the plunger case 22 in the tailstock, promoting plunger 23 moves axially, plunger 23 drives centring sleeve 24 workpiece 1 is held out against, and makes the biend of workpiece 1 receive certain preload pressure, guarantees that workpiece is in boring tumbling process, do not produce axial float, effectively prevent from accident such as to scrap because of workpiece necessarily causes with regard to tool damage and workpiece.
