Description
Technical field
This utility model relates to Machining Technology field, especially a kind of swash plate outer ring Drilling operation fixture.
Background technology
Owing to swash plate outer ring is flat-disk shape structure, it is provided centrally with axis hole, when its side carries out Drilling operation, needs to utilize locating shaft that swash plate outer ring sleeve is located at top, and utilizes the stationary positioned such as nut.This positioning fixture, its inefficiency, and also in clamping process, error is relatively big, causes machining accuracy low.
Utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology and to provide one can realize quick-clamping, and the swash plate outer ring Drilling operation fixture that positioning precision is high.
In order to achieve the above object, swash plate outer ring Drilling operation fixture designed by this utility model, it includes the connection dish for being connected with the chuck of lathe, connection dish is fixed with workpiece mounting plate, being fixed with the jacking block with centre bore on the workpiece mounting plate of the other end relative to connection dish, the centre bore center on jacking block is on same straight line with the center being connected dish；Workpiece mounting plate is provided with through hole, resilient sleeve is installed in through hole, described resilient sleeve is hollow cylinder structure, its structure includes fixed component and elastomeric element, fixed component is fixing with through hole to be connected, elastomeric element is positioned at the outside of through hole, and the groove being provided with some its wall thickness through at interval on elastomeric element；Being internally provided with up big and down small tapering stay column in resilient sleeve, the diameter of the top of tapering stay column is more than the minimum diameter at the elastomeric element of resilient sleeve；The lower end of described tapering stay column is connected with the expansion link of the cylinder being arranged on workpiece mounting plate lower surface.
The inwall of described elastomeric element is inclined-plane, and the diameter of upper end is more than the diameter of lower end；Tapering stay column in elastomeric element coordinates with elastomeric element inwall, and the tapering stay column in fixed component coordinates with the inwall of fixed component.
Being provided with two through holes on workpiece mounting plate, be provided with resilient sleeve and tapering stay column in each through hole, and the lower end of two tapering stay columns is all connected with the expansion link of cylinder by arm-tie, the expansion link of described cylinder is rotationally connected with the centre position of arm-tie.
Technique scheme, pulling by cylinder, realize tapering stay column to move down, the elastomeric element of resilient sleeve is strutted by moving process, cause its diameter to increase, thus realize realizing interference fit between the axis hole of the swash plate outer ring being set on elastomeric element, be fixed firmly, the course of processing will not loosen, it is ensured that machining accuracy.Convenient mounting and clamping simultaneously, only need to be fitted in resilient sleeve, and dismounting only need to simply be taken off, and can improve the efficiency of loading and unloading.
Swash plate outer ring Drilling operation fixture obtained by this utility model, it passes through resilient sleeve and the cooperation of tapering stay column, it is achieved the quick-clamping to swash plate outer ring, and efficiency is high, accurate positioning.
