Abstract

The utility model provides an automatic centring clamp for honing of a sleeve type part. According to the technical scheme, the automatic centring clamp comprises nuts, spherical surface pressing rings, conical surface pressing rings, cylindrical pressing sleeves, steel balls, steel ball clamps and a mandrel, wherein left and right structures of the mandrel are in symmetry, two shaft shoulders which are the same in structure and symmetrical in positions are disposed on the mandrel, the steel ball clamps which are tightly matched with the mandrel are arranged on outer sides of the shaft shoulders of the mandrel respectively, the steel ball clamps are positioned by the shaft shoulders, the steel balls are disposed in clamping grooves of the steel ball clamps, the cylindrical pressing sleeves which are movably matched with the mandrel are mounted on outer sides of the steel balls, the conical surface pressing rings are disposed on outer sides of the cylindrical pressing sleeves, the circular conical surfaces of the conical surface pressing rings are matched with the spherical surfaces of the spherical surface pressing rings, the conical surface pressing rings and the spherical surface pressing rings are movably matched with the mandrel, the nuts which are matched with screw threads of the mandrel are designed on outer sides of the spherical surface pressing rings, and the spherical surface pressing rings are locked and positioned by the nuts. The automatic centring clamp for the honing of the sleeve type part has the advantages that the structure is simple, performances are reliable, automatic centring can be achieved, two ends are tightly clamped, the producing efficiency can be increased, and the workpiece machining accuracy can be guaranteed.

Description

A kind of honing cover parts automatically centering fixture
Technical field
The utility model relates to a kind of honing cover parts automatically centering fixture, belongs to clamping tool for machine work technical field.
Background technology
In machining, usually to process the cover parts that some precision are higher, these are had to the honing of the cover parts of high-precision requirement, as the way that adopts conventional Zhi Jiahuo two, two directly to push up is carried out the cylindrical of honing workpiece, because fixture itself does not have the function of self centering, obviously the perpendicularity of the circular runout of the excircle of workpiece processing and endoporus and excircle of workpiece and endoporus and end face do not reach machining accuracy, because all will exceed outside drawing specification requirement.
Summary of the invention
The purpose of this utility model is just to provide a kind of honing cover parts automatically centering fixture, for addressing the above problem.
The technical solution of the utility model is: a kind of honing cover parts automatically centering fixture, comprise nut, sphere trim ring, conical surface trim ring, cylinder gland, steel ball, steel ball folder and axle, axle left and right symmetrical configuration, described axle is provided with two shaft shoulders of structure same position symmetry, the shaft shoulder outside of described axle is respectively provided with the steel ball folder with axle close-fitting, and located by the described shaft shoulder, in the clip slot of steel ball folder, be provided with steel ball, the outside of steel ball is provided with the cylinder gland of joining with axle work, cylinder gland outside is provided with conical surface trim ring, the taper seat of conical surface trim ring matches with the sphere of sphere trim ring, conical surface trim ring and sphere trim ring are all joined with axle work, sphere trim ring outside is provided with the nut matching with axle screw thread, sphere trim ring is located by nut check.
The beneficial effects of the utility model are: simple in structure, and dependable performance, self-centering, two ends clamp, and can enhance productivity and guarantee Workpiece Machining Accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, a kind of honing cover parts automatically centering fixture, comprise nut 1, sphere trim ring 2, conical surface trim ring 3, cylinder gland 4, steel ball 5, steel ball folder 6 and axle 7, axle 7 left and right symmetrical configuration, described axle 7 is provided with two shaft shoulders of structure same position symmetry, the shaft shoulder outside of described axle 7 is respectively provided with the steel ball folder 6 with axle 7 close-fittings, and located by the described shaft shoulder, in the clip slot of steel ball folder 6, be provided with steel ball 5, the outside of steel ball 5 is provided with the cylinder gland 4 of living and joining with axle 7, cylinder gland 4 outsides are provided with conical surface trim ring 3, the taper seat of conical surface trim ring 3 matches with the sphere of sphere trim ring 2, conical surface trim ring 3 and sphere trim ring 2 are all lived and are joined with axle 7, sphere trim ring 2 outsides are provided with the nut 1 matching with axle 7 screw threads, sphere trim ring 2 is by nut 1 locking positioning.While using the utility model clamping cover parts to carry out honing, first centering is sleeved on the utility model outer surface by workpiece 8, then the two that clamps respectively axle 7 with head of a bed scroll chuck and the tailstock scroll chuck of grinding machine, after proofreading and correct, with wrench, twist nut 1, by sphere trim ring 2 and conical surface trim ring 3, exert all one's strength stepless action on cylinder gland 4, this be due to the sphere of sphere trim ring 2 and the conical surface of conical surface trim ring 3 always circumference contact, so energy self-centering, thereby promoting steel ball 5 struts to workpiece 8 simultaneously, also just from two ends, left and right, locate simultaneously and clamped workpiece 8, now can carry out honing to the cylindrical of workpiece 8, after honing is good, unclamp nut 1, steel ball 5 is retracted along the conical surface of axle 7, take off workpiece 8, workpiece 8 cylindrical honing techniques finish.
