Abstract
The utility model discloses a clamp device for broaching machining of a taper hole key groove, belongs to the field of mechanical forging, and relates to the clamp device for forge piece machining. The technological structures of a base plate with a certain dip angle, a positioning spindle with a cutter passing groove and the like are mainly adopted. The clamp device for broaching machining of the taper hole key groove has the advantages of being accurate in positioning, strong in broaching stress, free of displacement in the machining process, high in machining precision and efficacy, convenient to clamp, low in clamping cost, and long in service life.
Description
Technical field
The utility model, about machining, is a kind of forging jig for machining device.
Background technology
Taper hole keyway traditional diamond-making technique is shear speed gear cutting processing, and high to the machining tool requirement, and cutter consumption is large, and cost is high, and working (machining) efficiency is low.Broaching processing is a kind of processing mode relatively more commonly used in machining.In broaching processing except equipment, broaching tool, fixture are the two large factors that affect the converted products quality, broaching tool is molding cutter, only the working position size is responsible for, and fixture will be responsible for broaching working position and other position relation of product, gap in broaching processing between workpiece and fixture location has a significant impact product quality, so fixture is most important to the broaching converted products, has not yet to see the ripe perfect processing clamp device of the broaching for the taper hole keyway.
Summary of the invention
The purpose of this utility model is to overcome the problem that there is the gap affects product quality between locating with fixture of workpiece in broaching processing in traditional shear speed gear cutting processing mode processing taper hole keyway, adopt the broaching processing technology to produce the taper hole keyway, a kind of safe, applicable, accurate positioning, taper hole keyway broaching processing clamp device that positioning gap is little are provided.
The technical solution of the utility model is: a base plate is arranged, the positioning compression mechanism consisted of bearing, standing screw, positioning screw, cushion block and pressing plate is arranged on base plate, two planes of base plate are not parallel, an inclination angle is arranged, dowel hole is arranged on base plate, and dowel hole is equipped with positioning core axle, and positioning core axle is conical, axial cutter groove is excessively wherein arranged, and base plate has the corresponding tool bore of crossing.
The utility model is arranged on broaching machine by base plate, during use, the taper hole of workpiece is enclosed within on positioning core axle, and workpiece compresses by hold-down mechanism, can carry out the broaching processing of taper hole keyway.If process the taper hole keyway of different taperings, the base plate of replaceable different angles and supporting positioning core axle, realize the processing of different taper hole keyways.
Due to the base plate and the positioning core axle location that adopt at an angle, angle is consistent with the taper hole angle, make the utility model accurate positioning, broach stressed strong, the workpiece process gap is little, non-displacement, has guaranteed the machining accuracy of taper hole keyway, convenient mounting and clamping, effect greatly improves, and cost obviously reduces, and has also extended the life-span of fixture simultaneously.
The accompanying drawing explanation
Fig. 1 is the utility model master cross-sectional schematic.
The A that Fig. 2 is the utility model Fig. 1 is to schematic diagram.
The B part that Fig. 3 is the utility model Fig. 2 is to schematic diagram.
The specific embodiment
The present embodiment is processed as the example explanation with knuckle screech owl taper hole keyway.
As shown in Figure 1, Figure 2,, a base plate 1 is arranged, the positioning compression mechanism consisted of bearing 2, standing screw 3, positioning screw 4, cushion block 5 and pressing plate 6 etc. is arranged on base plate 1, two planes of base plate 1 are not parallel, and an inclination angle is arranged, and on base plate 1, dowel hole arranged, dowel hole is equipped with positioning core axle 7, positioning core axle 7 is conical, and axial cutter groove 8 is excessively wherein arranged, and base plate 1 has corresponding tool bore 9 excessively.
In accompanying drawing, dotted portion is knuckle, base plate 1, positioning core axle 7 connect as a whole, the boss of base plate 1 is for concentric with the broaching machine main shaft, guarantee the depth dimensions of broaching taper hole keyway, and the relative base plate 1 of positioning core axle 7 is with angle of inclination, and angle is consistent with taper hole tapering angle, guarantee that the machining angle of taper hole keyway is correct.Positioning core axle 7 can guarantee accurate work piece positioning, firm.
Because the taper hole keyway has certain angle, so base plate 1 two sides is not parallel, its angle is according to the angle adjustment of product.
Positioning compression mechanism on base plate 1, guarantee that knuckle compresses, accurate positioning.The composition of this routine positioning compression mechanism is, a bearing 2 is arranged on base plate 1, and positioning screw 4, standing screw 3 are arranged on bearing 2, on positioning screw 4, standing screw 3, pressing plate 6 arranged, and clamp nut 10 is arranged on standing screw 3, and cushion block 5 is arranged on bearing 2.This be in the present embodiment for the positioning compression mechanism of knuckle, in accompanying drawing, turn to the nodal axisn neck to be supported on cushion block 5, and compress with pressing plate 6.If for the taper hole keyway broaching processing of other workpiece, can be according to the concrete condition of workpiece, the Design Orientation hold-down mechanism, all adopt conventional fixture positioning compression mode.
The connection of the connection of bearing 2 and base plate 1 and standing screw 3 etc. and bearing 2, adopt conventional fixture connected mode.The connection of positioning core axle 7 and base plate 1, the connection of base plate 1 and broaching machine, with bolts, for making the short and sweet knowledge figure of being convenient to of accompanying drawing, omitted set bolt and the connecting hole of this part in accompanying drawing.
