Technical field:
The present invention relates to a kind of mould bases formula tooth form final finishing device, be specifically related to tooth Profile Machining, the occasion of tooth form final finishing behind the plastic-coated, especially can be applicable to all kinds of splined shafts, cover before and after the plastic-coated finishing and be suitable for as broaching fixture.
Background technology:
Finishing process is widely used in the top layer of high request splined shaft, cover and handles, and can effectively reduce tooth surface abrasion and gearing noise.Finishing is the critical process that guarantees the profile of tooth overall target.The tradition tooth Profile Machining realizes tooth form final finishing through modes such as finishing lathe processing, the razor that repairs a die, honings, has that shaping efficient is lower, complex process and a precision problem of unstable.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of mould bases formula tooth form final finishing device, this device can realize that synthesis precision is high after a finishing moulding and the shaping to workpiece accurate centering location.
Technical solution problem of the present invention adopts following technical scheme:
Mould bases formula tooth form final finishing device, setting is positioned at four leads on four summits of rectangle, in said lead bottom fixing following mould bases is set; Lead top is provided with the top mold frame that can move up and down; Be provided with guide cylinder longitudinally at said mould bases center down, be provided with plunger in the guide cylinder, the bottom and the lower piston rod of plunger connect firmly; In the down top lower counterbore that is positioned plunger, and be installed with the center line and the finishing cutter of top central lines down at the said top of mould bases down;
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, and handle is set, and said 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 invention also is:
Top in said 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; Below connector, be provided with a spheroid, the below of spheroid is provided with the pressure-bearing mandrel with said through hole interference fit, and the top of said stage clip is spring base with said pressure-bearing mandrel; Said pressure-bearing mandrel is dumb-bell shape, center and said 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 present technology, beneficial effect of the present invention is embodied in:
The present invention is through 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 high (can guarantee simultaneously jump in linearity, footpath, profile of tooth symmetry) all by axle, location well radially; Applied range can be realized the processing to axle, cover parts through changing top form.
The present invention 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 invention.
Label among 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 combine accompanying drawing that the present invention is described further.
The specific embodiment:
Embodiment: combine Fig. 1, the mould bases formula tooth form final finishing device of present embodiment is positioned at four leads 1; These four leads are positioned on four summits of a rectangle, and fixing following mould bases 2 is set in lead bottom, and 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, is provided with plunger 5 in the guide cylinder, and the bottom of plunger and lower piston rod 6 connect firmly; Top at plunger 5 is provided with lower counterbore, and following top 7 are positioned in the lower counterbore of plunger, and is installed with finishing cutter 8 at the top of following mould bases 2; The end face of finishing cutter is fixing with pressure knife block 17, the center line of finishing cutter 8 and following top central lines.
Be provided with dead head 9 at the center of top mold frame 3, in last dead head, be provided with toply 10, go up top 10 center line and top 7 central lines down; Being provided with the top mold frame at last top top is the stage clip 11 of spring base; Handle 12 is set, and handle 12 middle parts and top mold frame 3 are hinged, and the front end of handle radially passes dead head 9 and with last top 10 hinged; Handle is equivalent to a lever, and the top of top mold frame 3 and upper piston rod 13 connect firmly.
As further improvement of the present invention; Top in top mold frame 3 has through hole; The top of top mold frame is installed with upper piston rod 13 and forms the connector 14 that connects firmly; Below connector, be provided with a spheroid 15, the below of spheroid is provided with the pressure-bearing mandrel 16 with said through hole interference fit, and the top of stage clip 11 is spring base with pressure-bearing mandrel 16; Pressure-bearing mandrel 16 is dumb-bell shape, center and said 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.
