Be provided with dead head at the center of top mold frame, in last dead head, be provided with top and its center line and following top central lines, being provided with the top mold frame at last top top is the stage clip of spring base, handle is set, described handle middle part is hinged with top mold frame, the front end of handle radially passes dead head and with last top hinged, the top and the upper piston rod of top mold frame connect firmly.
Design feature of the present utility model also is:
Top in described top mold frame has through hole, the top of top mold frame is installed with upper piston rod and forms the connector that connects firmly, be provided with a spheroid below connector, the below of spheroid is provided with the pressure-bearing mandrel with described through hole interference fit, and the top of described stage clip is spring base with described pressure-bearing mandrel; Described pressure-bearing mandrel is dumb-bell shape, its middle part and described through hole interference fit, and the outer top mold frame of the top and the bottom of pressure-bearing mandrel and through hole is the step surface crimping.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is by top can accurately the location axle, cover parts under last top the reaching of central lines, the center line of fixed finishing cutter also with the central lines of axle, cover parts, workpiece to be machined (axle, cover) in the finishing cutter through out-of-date, the plastic-coated top layer of workpiece can be processed extremely even, the one-shot forming work efficiency is fast; Because of last top and down top, so shaping synthesis precision height (can guarantee simultaneously jump in linearity, footpath, profile of tooth symmetry) all by axle, location well radially; Applied range can be realized processing to axle, cover parts by changing top form.
The utility model is provided with spheroid between connector and pressure-bearing mandrel, when the downward application of force of upper piston rod is descending with the promotion workpiece to be machined, spheroid can be corrected the pressure shift phenomenon, effectively guaranteed the stepless action of upper piston rod applied force on the central axis of workpiece, can guarantee simultaneously that jump in linearity, footpath, the profile of tooth symmetry.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 lead, 2 times mould bases, 3 top mold frame, 4 guide cylinders, 5 plungers, 6 lower piston rods, 7 times are top, 8 finishing cuttves, and dead head on 9, top on 10,11 stage clips, 12 handles, 13 upper piston rods, 14 connectors, 15 spheroids, 16 pressure-bearing mandrels, 17 pressure knife blocks, 18 workpiece.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1, the mould bases formula tooth form final finishing device of present embodiment, be positioned at four leads 1, these four leads are positioned on four summits of a rectangle, in the lead bottom fixing following mould bases 2 is set, lead top is provided with the top mold frame 3 that can move up and down along lead, center at following mould bases 2 is provided with guide cylinder 4 longitudinally, be provided with plunger 5 in the guide cylinder, the bottom of plunger and lower piston rod 6 connect firmly, and are provided with lower counterbore on the top of plunger 5, top 7 be positioned in the lower counterbore of plunger down, and being installed with finishing cutter 8 at the following top of mould bases 2, the end face of finishing cutter is fixing with pressure knife block 17, the center line of finishing cutter 8 and top central lines down.
