Description
Technical field
The utility model relates to a kind of positioning tool, particularly a kind of trigonometric expression positioning tool
Background technology
Along with the progress of science, increasing design relates to mechanical field, and the processing of increasing part also depends on machinery, but mechanically traditional positioning tool mounting process is more single, and operating efficiency is also lower.
Whether the torsional direction of universal joint by it there is obvious elasticity can be divided into rigid universal joint and flexible universal joint, it is rigid universal joint that hinge type by part connects transmission power, transmitting power by elastic part is flexible universal joint, rigid universal joint can be divided into nonconstant velocity universal joint again, Near constant velocity universal joint and constant velocity cardan joint.The most frequently used on automobile is cross shaft rigid universal joint, can ensure that (being generally 1-20 degree Celsius) transmits power reliably when the between centers angle of cut changes, structure is simple, transmission efficiency is high, but also there is certain shortcoming, single cross shaft rigid universal joint can not transmit movement at the uniform velocity when there being angle, driving shaft constant speed rotation one week, and periodically surmounting and retardation change for twice appears in driven shaft.Near constant velocity universal joint comprises dual cardan type U-joint, three and connects fork-type universal-joint, dual cardan type U-joint power transmission shaft is reduced to minimum universal joint constant speed drive device, it is made up of two Hooke's joints, and allow institute join two angular differences distances comparatively greatly (can reach 0 degree), bearing seal is good, efficiency is high, reliable operation, easily manufactured, but structure is more complicated, appearance and size is comparatively large, and number of parts is more; Three to connect fork-type universal-joint be two eccentric yokes, and two three bearing pins and six needle bearings composition, allow institute join diaxon angle comparatively greatly (can reach 4 degree), be easy to seal.Constant velocity cardan joint is divided into weiss universal joint and rzeppa joint, and weiss universal joint structure is comparatively simple, but the unit pressure suffered by steel ball is comparatively large, and wearing and tearing are very fast; By force, efficiency is high, compact dimensions, easy for installation for rzeppa joint bearing capacity and shock-resistant ability.
The Vehicle Processing mode process of traditional BJ type bell housing is comparatively loaded down with trivial details, and often can be trained off by centre bore because center looks for inaccurate during processing parts center, and therefore the part of processing can produce error, and processing parts has limitation.
Utility model content
It is quick that the purpose of this utility model is to provide a kind of convenient mounting and clamping, the trigonometric expression positioning tool that can enhance productivity.
The technical scheme realizing the utility model object is: the utility model has pull bar, fixing ball, stop rod and circular shaft, circular shaft one end is provided with detent mechanism, circular shaft is provided with a through hole along the axis of circular shaft, through hole is provided with a cylindrical hole in the detent mechanism end of circular shaft, described detent mechanism comprises equally distributed three slotted eyes of periphery along circular shaft, the hole heart of three slotted eyes is evenly distributed on in the plane of the axes normal of circular shaft, along the periphery of circular shaft being uniformly distributed three chutes, the center of three chutes is on the same plane of the axes normal with circular shaft, three chutes extend along circular shaft from detent mechanism end to the other end of circular shaft, between the plane upper hopper chute and slotted eye of the axes normal of circular shaft, angle is 60 degree, each slotted eye internal fixtion is provided with a fixing ball, pull bar is slidably connected in the through hole of circular shaft, pull bar is being provided with a disk coordinated with cylindrical hole near detent mechanism end, disk to distribute three grooves along the even circumferential of disk, the center of three grooves in the plane of the axes normal with circular shaft and the center of three grooves at grade, a stop rod is hinged with in each groove, when machine drawing pulls pull bar, stop rod on pull bar is along chute slide downward, when stop rod non-articulated termination contacts clutch can raceway groove, workpiece is just locked by frock.
Above-mentioned positioning tool is also provided with a tooling base, and tooling base is provided with connecting hole.
The non-articulated end of above-mentioned stop rod is spherical shape.
The utility model has positive effect: (1) the utility model clamping process is comparatively simplified; (2) center of processing parts can be aimed at accurately, convenient overall processing.(3) working efficiency can be improved, for enterprise brings more interests.
