Description
Technical field
The utility model relates to a kind of jig, particularly relates to a kind of jig structure of fine finishining vehicle bridge-crossing case component, belongs to Machine Tool Fixture Design manufacturing technology field.
Background technology
Vehicle bridge-crossing case component is made up of casing, case lid two parts, and casing and case lid are shaped with two respectively for installing the parallel hole of gear shaft, and holes requires axis coaxle.Because casing and case lid all belong to thin-walled parts, therefore the locating oil cylinder that many are encircled casing or case lid must be set in clamp for machining, the distortion produced because being subject to cutting force to prevent workpiece, the positional precision of impact processing and form accuracy.In traditional processing technology, usually casing, case lid are processed respectively as two parts, that is: on a machine tool, batch machining goes out casing; At another a machine tool or change frock batch machining go out case lid on same a machine tool.This process depends on that the precision of jig is to ensure the holes axiality on casing and case lid completely, and this just determines its positional precision must have error.Therefore, by the vehicle bridge-crossing box body, the case lid that process respectively, can not meet the axiality requirement after assembling, the overall performance of automobile can be caused to decline.
Summary of the invention
For the technical deficiency existing for traditional processing automobile bridge case component technique, the utility model provides a kind of jig of fine finishining vehicle bridge-crossing case component.
The technical solution of the utility model is: a kind of jig of fine finishining vehicle bridge-crossing case component, the clamp system, auxiliary support mechanism, the obvolvent position-limit mechanism that comprise clamp body, the casing of bridge case and case lid and be fixedly connected on clamp body, described clamp body is provided with three anchor points in same plane; Described casing is provided with datum level, and it to be inserted in clamp body and datum level and three anchor points are leant; Described case lid is provided with the mating surface fitted with casing fitting surface, and it fits also tight after the first work step machining box fitting surface by the fitting surface that many bolts and casing have been processed; Described clamp system splits by three anchor points on clamp body, for clamping casing; Described auxiliary support mechanism is arranged on and prevents casing datum level from producing on the position of distortion by cutting force effect; Described obvolvent position-limit mechanism is made up of eight locating oil cylinders, and wherein four locating oil cylinders are arranged on around the outer wall of casing, and centrally cross section is symmetrical, and its single rod is vertical with cabinet exterior, and obvolvent cabinet exterior when stretching out, is characterized in that:
Other four locating oil cylinders in described obvolvent position-limit mechanism are arranged on around the outer wall of case lid, and single rod in oil cylinder and case lid outer wall vertical;
Four described locating oil cylinders are symmetrical along the central cross-section of case lid;
Single rod in described four locating oil cylinders stretches out obvolvent case lid after case lid to be fitted by many bolts and casing and be tight.
The utility model owing to having set up the oil cylinder of four spacing case lids on clamp body, thus two work steps that the two procedures of tradition machining box and case lid is respectively merged in a procedure are completed, the wherein mating surface of a work step machining box, complete three-point fix by positioning and clamping mechanism to clamp, a supplemental support is completed by auxiliary support mechanism, by four locating oil cylinder obvolvent cabinet exteriors, prevent the distortion because cutting force produces; Wherein two work steps are after casing completion of processing, by many bolts by manufactured for case lid mating surface and the mating surface being combined in casing to be formed an assembling overall, and four locating oil cylinder obvolvent case lid outer walls by setting up, prevent the case lid distortion because cutting force produces, thus go out coaxial aperture in a same synchronous processing on the whole.
The utility model has modern design, the advantage that simple and reasonable, Working position precision is good, production efficiency is high.
