Abstract
The invention provides a positioning fixture for a pitch circle of a bevel gear shaft, which is suitable for a spiral bevel gear shaft without a guide bearing guard. The positioning fixture is convenient to use; the bearing guard can be processed by positioning of the bevel gear pitch circle, so that the coaxility of the bearing guard and the bevel gear pitch circle is better and the running process is more stable and lower in noise. The positioning fixture comprises a spring, a taper shank, an annular clamp seat with a concave axial section, and a workpiece guide clamp head fixedly mounted on the annular clamp seat for guiding and rotating workpieces; the annular clamp seat is composed of a bottom plate and an annular clamp wall fixedly connected with the bottom plate; two surfaces of the bottom plate are the bottom surface and the concave surface of the annular clamp seat; the taper shank is fixedly connected to the bottom surface of the bottom plate; a cavity is formed between the annular clamp wall and the concave surface; an annular groove is arranged along the circumferential direction of the annular clamp wall at the top angle of the annular clamp wall close to the cavity; three positioning steel balls are arranged in the annular groove; positioning through holes are arranged on the positioning steel balls; three connected through holes are also arranged on the annular clamp wall; the positioning steel balls are positioned in the annular groove by the spring after the spring passes through the connected through holes and the positioning through holes; and the radial section of the annular groove is an arc surface.
Description
Technical field
Present technique relates to a kind of frock that is used for the processing of spiral bevel gear, relates in particular to a kind of bevel gear shaft pitch circle positioning fixture.
Background technology
The processing of existing spiral bevel gear bearing guard all is to locate the grinding bearing shelves with two centre bores.This grinding method makes the axiality of spiral bevel gear pitch circle and bearing guard have the deviation of 0.04-0.08mm all the time.For a long time, such axiality level has influence on the final noise of bevel gear product always, directly makes the product quality class of bevel gear.Suddenly needing more convenient, rational in infrastructure frock clamp solves this problem.
Summary of the invention
Present technique technical problem to be solved is the deficiency to above-mentioned existing counting, and a kind of bevel gear shaft pitch circle positioning fixture that is applicable to no guide bearing shelves spiral bevel gear axle is provided.This bevel gear shaft pitch circle positioning fixture is easy to use, can locate the machining bearing shelves with the bevel gear pitch circle, makes bearing guard and bevel gear pitch circle axiality better, and running noise is lower, more steady.
To solve the above technical problem, the technical solution adopted for the technique: A bevel gear shaft pitch circle of the positioning jig, including spring, taper shank, an axial cross-section of the annular concave clamp and fixed on the seat with the ring binder in turn a workpiece-oriented guide chuck; ring clamp from the floor and the bottom wall of the fixed connection ring binder composition, respectively, on both sides of the bottom plate clamp ring and concave bottom, taper shank fixedly connected to the bottom surface of the base plate , the ring clamp to the cavity between the wall and the concave surface, the ring binder wall near the top corners of the cavity and along the circumferential wall of the annular clamp with an annular groove, the annular groove equipped with three positioning balls, positioned on the ball a positioning through hole; wall also has a three ring binder connection through-hole; spring through the connection through-hole and the positioning through-hole will be positioned in the annular groove ball positioned; radial section of the annular groove of the arc surface.
As the further improved technical scheme of present technique, this bevel gear shaft pitch circle positioning fixture also comprises the grinding spindle guiding chuck that is used to lead the said ring-type holder of commentaries on classics.
Present technique adopts low highly for steel ball workpiece is positioned, and the right spring point of positioning ball is in annular groove, so positioning ball can have micro displacement, thereby makes the location of workpiece more accurate.Present technique can guarantee that the axiality of machined surface and bevel gear pitch circle reaches 0.005-0.045mm in a word, also can reach the effect that running is steady, reduce noise better.

The specific embodiment
Referring to Figure 1, the pitch circle of the bevel gear shaft positioning jig, including spring? 1 taper? 2, the axial cross section of the concave annular clamp? 3? And fixedly mounted in the annular clamp? 3? Used on transfected work? 13? workpiece guide chuck? 4; ring clamp? 3? from the floor? 5 and the bottom? 5? fixedly connected ring binder wall? 6? constitute, floor? 5? both sides were ring clamp? 3? bottom? 3-1? and concave 3-2, taper shank? 2? fixedly connected to the base plate? 5? bottom? 3-1?, the ring binder wall? 6? with concave? 3-2? between the cavity? 7, the ring binder wall? 6? close the cavity? 7? the top corners and along the ring binder wall? 6? with an annular groove in the circumferential direction? 8, said annular recess groove? 8? radial section a quarter arc.Can be provided with at least three locking balls 9 in the annular groove 8 and be provided with positioning through hole 10, locking ball 9 is three in the present embodiment; On the annular double wall 6 near the position of annular groove 8 also be provided with 11, three connecting through holes 11 of connecting through hole at least be evenly distributed on annular double wall 6 circumferentially; Spring 1 passes connecting through hole 11 and with positioning through hole 10 locking ball 9 is positioned in the annular groove 8.Also comprise and be used to lead the grinding spindle guiding chuck 12 that changes said ring-type holder 3.Locking ball 9 adopts the pitch circle locking ball.Spring 1 adopts hairspring, can with connecting through hole and positioning through hole is suitable to be as the criterion.Taper shank adopts the 4# Morse taper shank.
The operation principle of present technique is: taper shank 2 directly connects the grinding machine spindle hole, and being led by grinding spindle guiding chuck 12 changes this bevel gear shaft pitch circle positioning fixture, leads the part 13 of changing a job again by workpiece guiding chuck 4; 8 li of the annular grooves that three pitch circle locking balls float and are positioned 1/4 sphere with hairspring, three steel balls are roughly divided equally bevel gear shaft are carried out the pitch circle location, set upright the location by active thimble 14 more simultaneously.Promptly can carry out grinding or turning behind the clamping like this to machining area.
