Abstract
The utility model relates to the field of fixtures and in particular relates to a gear circular hole grinding fixture. At least three pitch cylinders are sheathed in an opening elastic lantern ring base, are fixed by use of rivets and are uniformly distributed and riveted on the inner end face of a lantern ring. By adopting the technical scheme, the gear circular hole grinding fixture adopts a pitch circle centering manner, a gear is centered and fixed in an elastic lantern ring by virtue of the pitch cylinder by utilizing the contraction elastic force of the open elastic lantern ring base, and the elastic lantern ring and the gear are adsorbed onto a spindle so as to be subjected to hole grinding by utilizing the magnetic force of a spindle of an internal grinding machine of a bearing ring. The elastic lantern ring is small in inward contraction force and small in gear deformation, thus the variation of an inner hole is slight after the gear circular hole grinding fixture is demounted, and the mounting and operating requirements of internal hole dimension and cylindricity are guaranteed.
Description
Technical field
The utility model relates to the anchor clamps field, is a kind of gear circular hole clamp.
Background technology
With the roller gear of circular hole supporting, after the aperture carburized surface cure process, all, can not directly install and use in it because of the influence of distortion, need make installation and result of use that endoporus fine finishining guarantees part.Usually adopt the pitch circle centralizer to carry out inner hole grinding processing.Generally speaking, the abundant rigidity of gear is better, takes certain clamping force, and gear can not produce strain, and influences the endoporus processing effect.Little when the diameter difference of the root circle of ring-type circular hole gear and endoporus, when adopting common pitch-line chuck clamping gear, gear can produce strain because of entity is thin.After the inner hole grinding processing, when not eliminating chucking power, measure endoporus physical dimension and cylindrical form error and all meet the requirements; Eliminate when clamping force, part restores to the original state, and this moment, the bore size and dimension just changed, and made part can not satisfy design and installation, instructions for use.
Summary of the invention
The purpose of the utility model is circular hole processing clamping device, i.e. the gear circular hole clamp that a kind of roller gear will be provided.
The technical scheme of the utility model is: be made up of rivet, pad, soket head cap screw, it is characterized in that pitch cylinder is enclosed within the opening elastic collar seat, fix with rivet, to be no less than three quantity, be uniformly distributed with riveting on collar inner face.
Owing to adopted technique scheme; This device adopts pitch circle centering form; Utilize the contraction elasticity of opening elastic collar seat; Through pitch cylinder gear centering is fixed in the elastic collar, utilizes the magnetic force of internal grinder for bearing race main shaft again, elastic collar and gear are adsorbed on carry out grinding out on the main shaft and process.Because the power that contracts in the elastic collar is less, gear shifting quadrant texturing is less, so after unloading, endoporus changes little, thereby has guaranteed the requirement of installing and using of interior hole dimension and cylindricity.
Description of drawings
Fig. 1 is the structural representation of facing of the utility model.
Fig. 2 is that cross-sectional view is looked on the left side of the utility model.
In the drawings: 1, opening elastic collar seat; 2, pitch cylinder; 3, rivet; 4, pad; 5, soket head cap screw.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
In Fig. 1 and Fig. 2, pitch cylinder 2 is enclosed within the opening elastic collar seat 1, and is fixing with rivet 3, to be no less than three quantity, is uniformly distributed with riveting on collar inner face, overlaps Upper gaskets 4 with soket head cap screw 5 and is fixed on the elastic collar seat 1.
The inside and outside two ends of opening elastic collar seat 1 and should be parallel; The inwall circle seat of collar opening pawl should be coaxial with collar seat centering cylindrical; The inwall circular diameter of opening elastic collar seat 1 opening pawl should be slightly less than that pitch cylinder 2 and gear be close to strides excellent carpenters square cun, to guarantee opening elastic collar seat 1 enough chucking powers and grip is arranged.Be pressed into part, tighten screw, confirm that part puts in place and, the processing of can installing with after the collar, pitch cylinder 2 closely contact non-loosening.After the processing, unclamp screw and take off part, accomplish part working procedure processing process.
