Description
Technical field
The utility model designs a kind of gear fixture, is that one kind adapts to more specification, and is not likely to produce tired specifically
The bevel gear fixture of labor.
Background technique
In the manufacturing process of bevel gear, need first to produce the conical surface annulus blank of shape and bevel gear acquaintance, then benefit
The conical surface is processed with gear-hobbing machine or tooth milling machine.Patent No. CN201521041756.7 disclose a kind of milling of spiral bevel gear plus
Clamping apparatus, including bottom plate, rise core and guide post, the cylinder of the pore area taper core that rises coaxially is fixed in circular ring shape bottom plate and end
On platen face, the guide post activity of round belt back draught is co-axially located at core center of rising, the other end of guide post outside end
It is connected with locking cylinder piston, also, the back draught phase of the taper of the core end inner hole that rises and guiding column end outer circle
Match.Conical surface annulus blank can be firmly fixed on the work top of lathe by this design, but the swell increment ten for the core that rises
It is point limited, the bevel gear of less specification can only be fixed, and deformation occurs bevel gear is fixed the core hair that easily makes to rise by the core that rises
Raw fatigue, and then the core that makes to rise loses fixed effect.
Utility model content
The utility model aim, which is intended to provide one kind, adapts to more specification, and is not likely to produce the bevel gear folder of fatigue
Tool.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
Bevel gear fixture, the bottom plate including circular ring shape, circular guide ring, support rod and propulsion round bar；The guide ring
It is fixed on bottom plate, and the central axes of guide ring and the central axes of bottom plate are in same straight line；The support rod is for pushing against umbrella tooth
The inner wall of blank is taken turns, which, which wears, connects on guide ring, and at least three support rod radial equipartitions are on guide ring；It is described to push away
Into round bar for pushing support rod activity, the central axes of the propulsion round bar and the central axes of guide ring are in same straight line, and promote
Round bar is fixed with coniform propulsion head towards one end of guide ring, fixes away from one end of guide ring and the mandril of propulsion cylinder
Connection；The mandril of the propulsion cylinder pushes when promoting round bar mobile to guide ring, promote head be gradually inserted in guide ring and with
The interior end in contact of support rod, make support rod with promote continuing to move to for head and be gradually pushed outwardly, and then make the outer end of support rod tight against
Bevel gear blank is fixed on the inner wall of bevel gear blank.
Further, the end of the inner end of the support rod is hemispherical so that the inner end of support rod with promote head contact more
Add smoothly, and then enables that head is promoted more easily to release support rod.
Further, the outer end of the support rod is fixed with support block, is contacted by support block with the inner wall of bevel gear blank, increases
Contact point, to improve the fixed effect to bevel gear blank.
Further, the top surface radial equipartition of the bottom plate has at least two locking notches in the form of slot, and the locking lacks
It is fixed with guide thread bar on the inner wall of mouth, wears the locking being connected to for locking bevel gear blank outer end on the guide thread bar
Block；The outer end of the guide thread bar is provided with the propulsion annulus for pushing latch segment mobile, the inner wall for promoting annulus
On be provided with the screw thread matched with guide thread bar；Annulus can be promoted to make by turning after support rod is fixed by bevel gear blank
Latch segment is moved along guide thread bar, and then is pushed against in the outer rim of bevel gear blank, further fixes bevel gear blank.
The utility model compared with prior art the advantages of be: promote round bar by mobile, make to promote head by support rod from guiding
It is released in ring and then contradicts the outer end of support rod on the inner wall of bevel gear blank, achieved the effect that bevel gear is fixed；Because supporting
Bar has biggish operating range, therefore can fix the bevel gear blank of more specifications, and pushes against process and pass through mechanical activity
It carries out, is not likely to produce fatigue, the longer time can be used.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that bevel gear blank is fixed on the base structural schematic diagram；
Fig. 3 is the structural schematic diagram of pedestal；
Main element symbol description is as follows: 1, bottom plate；2, guide ring；3, support rod；4, round bar is promoted；5, support block；6, it locks
Notch；7, guide thread bar；8, latch segment；9, bevel gear blank；10, annulus is promoted；11, block is tightened.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
Embodiment one
Referring to attached drawing 1 to 3, bevel gear fixture in figure, the bottom plate 1 including circular ring shape, is used for circular guide ring 2
Push against the support rod 3 of 9 inner wall of bevel gear blank, for pushing the movable propulsion round bar 4 of support rod 3；The guide ring 2 is integrally fixed on bottom
On plate 1, and it is coaxial with bottom plate 1；The support rod 3 is round bar, is provided on guide ring 2 for the movable circular hole of support rod 3, support rod 3 passes through
