Abstract
The utility model relates to an expansion sleeve type gear grinding clamp which comprises a clamp mandrel, an expansion sleeve, a gland nut and a locknut. The expansion sleeve type gear grinding clamp is characterized in that outer threads are arranged on the locknut and an outer flange is arranged on the portion, close to the left end face by 3mm-5mm, of the outer circumference face; an inner flange is arranged on the inner circumference face of the right end of the expansion sleeve and a locating boss is arranged on the outer circumference face of the left end of the expansion sleeve; the locknut is tightly screwed on mandrel threads of the clamp mandrel; the locknut is sleeved with the expansion sleeve, the expansion sleeve is sleeved with a part, and the gland nut is tightly screwed on the outer threads of the locknut, so that the expansion sleeve moves leftwards and the part is tightly expanded through the locating boss arranged on the expansion sleeve. The expansion sleeve type gear grinding clamp is simple in structure, enables the part to be assembled and disassembled easily and conveniently and is accurate in locating, stable in part machining quality, free of requirement for knocking of the part or the clamp when the part is assembled and disassembled, free of damage to the part and the clamp and capable of shortening the assembly and disassembly time of the part, enabling the outer conical face of the clamp mandrel to be well matched with the inner conical face of the expansion sleeve and improving the machining efficiency and the pass percent of the part.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of expansion sleeve type gear grinding clamp.
Background technology
Expansion sleeve fixture is at present in particularly application a kind of fixture form of eliminating gap more and more widely in gear mechanism processing of mechanical processing industry.Traditional expansion sleeve type gear grinding clamp is by clamp nut, the inner conical surface of ringfeder to be matched with the male cone (strobilus masculinus) of fixture axle, makes it to produce an outside expanding force, thereby completes the tensioner to inner bore of part.Its shortcoming is: after part processes, after clamp nut is unclamped, ringfeder inner conical surface can not be automatically separation with the male cone (strobilus masculinus) of fixture axle, the part processing can not unclamp from fixture automatically, need to knock the part processing with copper rod, make ringfeder inner conical surface separation with axle male cone (strobilus masculinus), just can make part unclamp from fixture.Inconvenient operation, if improper owing to knocking, also very easily causes colliding with of part and fixture, even causes part or fixture to damage.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, easy to operate, part handling easily, the expansion sleeve type gear grinding clamp of accurate positioning.
Expansion sleeve type gear grinding clamp of the present utility model, comprises fixture axle, ringfeder, clamp nut and locking nut, it is characterized in that: described locking nut is provided with external screw thread, and the outer circumference surface of 3～5 millimeters of the end faces of keeping left is provided with outward flange; Described ringfeder right-hand member inner peripheral surface is provided with inward flange, left end outer circumference surface is provided with positioning boss; Locking nut screwing is on the axle screw thread of fixture axle; Ringfeder is enclosed within on locking nut, and part is enclosed within on ringfeder, and clamp nut is tightened on the external screw thread of locking nut, and ringfeder is moved to the left, and the positioning boss on it is by part tensioner.
In order better to realize above-mentioned purpose:
The described male cone (strobilus masculinus) of fixture axle and the inner conical surface of ringfeder have identical cone angle.
The utility model is simple in structure, handling part is easily convenient, accurate positioning, the part quality of processing is stable, during dismounting part, do not need to knock part or fixture, not injuring part and fixture, has reduced lay day of part, the male cone (strobilus masculinus) of fixture axle and the inner conical surface of ringfeder are worked good, and have improved working (machining) efficiency and the qualification rate of part.

The specific embodiment
Expansion sleeve type gear grinding clamp of the present utility model, comprises fixture axle 1, ringfeder 2, clamp nut 3 and locking nut 4.Locking nut 4 is provided with external screw thread 7, and the outer circumference surface of 4 millimeters of the end faces of keeping left is provided with outward flange 6.Ringfeder 2 right-hand member inner peripheral surfaces are provided with inward flange 10, and left end outer circumference surface is provided with positioning boss 9.The male cone (strobilus masculinus) 12 of fixture axle 1 has identical cone angle with the inner conical surface 11 of ringfeder 2, and cone angle is 30 degree.
By fixture axle 1 clamping on the main shaft of lathe, locking nut 4 is screwed on the axle screw thread 13 of fixture axle 1, ringfeder 2 is enclosed within on locking nut 4, part 5 is enclosed within on ringfeder 2, and lean against on the location end face 14 of fixture axle 1, clamp nut 3 is enclosed within on the external screw thread 7 of locking nut 4 and tightens left gradually, and ringfeder 2 is moved to the left, positioning boss 9 on it, by part 5 tensioners, can be processed part 5.
During dismounting part, only need unclamp locking nut 4, the outward flange 6 of locking nut 4 touches with the inward flange 11 of ringfeder 2, drives ringfeder 2 to move right, and makes the inner conical surface 11 of ringfeder 2 and the male cone (strobilus masculinus) 12 of fixture axle 1 separation, and expanding force disappears, and just can take off part 5.
Handling part fast and easy, time saving and energy saving, the male cone (strobilus masculinus) 12 of fixture axle 1 is worked good with the inner conical surface 11 of ringfeder 2, and accurate positioning has improved working (machining) efficiency and the crudy of part.
