Abstract
The utility model relates to a combined clamp for processing a bearing bush. The aim of changing bearing bush processing orders is fulfilled through ingenious match among clamps. The processing method comprises the following steps of positioning two bearing bushes by using the combined clamp and a three-jaw chuck to process an external flange and an inner circle; processing an external circle by matching the three-jaw chuck and a jacking clamp. The steps of welding and cutting at last in the traditional bearing bush processing process are prevented, so that deformation is relatively low, and the precision can be effectively guaranteed.
Description
Technical field
The utility model relates to a kind of bearing shell formula processing built-up jig, improves the machining accuracy of bearing shell by changing the processing sequence of bearing shell.
Background technology
Traditional bearing shell processing is by the whole rear upper lathe of tin welding one, to process inside and outside circle by cutting bearing shell open, after process finishing, after reusable heat water boil tin, separate, inconvenient operation is time-consuming like this, and inefficiency can not guarantee product quality simultaneously, its reason is in welding process and is finally cut open in process, because relate to the variation of heat and due to the character of material, distortion to a certain extent always occurs, its precision can be subject to certain impact.
Utility model content
The utility model is for above-mentioned defect, and object is to provide a kind of simple in structure, bearing shell processing built-up jig that can guarantee bearing shell machining accuracy.
The technical solution adopted in the utility model is for this reason: the utility model comprises scroll chuck, by two sections, is the separating-closing type fixture that semicircle combines, and and the roof pressing type fixture that coordinates of bearing shell outward flange; Separating-closing type fixture inner surface and bearing shell cylindrical match, and the downward flange of roof pressing type clamp ends forms a snap ring and blocks bearing shell outward flange.
A bearing shell processing method, carry out according to the following steps:
1) two bearing shells cutting open are fixed with modular fixture and scroll chuck, then processed inner circle and outward flange;
2), after inner circle and outward flange completion of processing, with roof pressing type clamp bearing shell outward flange, then, by the dismounting of separating-closing type fixture, carry out the processing of cylindrical;
3) after completion of processing, bearing shell is grabbed chuck and roof pressing type fixture and dismantled from three, complete processing.
The utility model has the advantages that: the utility model is by the ingenious cooperation between each fixture, reach the object that changes bearing shell processing sequence, processing method of the present utility model is first two bearing shells first to be carried out to the processing of outward flange and inner circle with modular fixture and scroll chuck location; Then by the cooperation of scroll chuck and roof pressing type fixture, carry out the processing of cylindrical, it has avoided welding and the step of finally cutting open in traditional bearing shell process, thereby its distortion is less, and precision can effectively be guaranteed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model modular fixture.
Fig. 2 is the structural representation of the utility model roof pressing type fixture.
The specific embodiment
The utility model comprises scroll chuck, by two sections, is the separating-closing type fixture that semicircle combines, and and the roof pressing type fixture that coordinates of bearing shell outward flange; Separating-closing type fixture inner surface and bearing shell cylindrical match, and the downward flange of roof pressing type clamp ends forms a snap ring and blocks bearing shell outward flange.
A bearing shell processing method, carry out according to the following steps:
1) two bearing shells cutting open are fixed with modular fixture and scroll chuck, then processed inner circle and outward flange;
2), after inner circle and outward flange completion of processing, with roof pressing type clamp bearing shell outward flange, then, by the dismounting of separating-closing type fixture, carry out the processing of cylindrical;
3) after completion of processing, bearing shell is grabbed chuck and roof pressing type fixture and dismantled from three, complete processing.
