Description
Technical field
This utility model relates to the process equipment field of automobile air conditioner compressor, the embossing key fixture of especially a kind of automobile air conditioner compressor bent axle.
Background technology
Spline on existing axis body mostly adopts annular knurl button apparatus to roll, and its positioning accuracy request is higher, owing to needing to rotate behind location, it is necessary to ensure that with one heart, often produce bigger error, affect the precision of its spline in the course of processing.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction to solve the deficiency of above-mentioned technology, can be rapidly performed by the embossing key fixture of the automobile air conditioner compressor bent axle of spline compacting.
In order to achieve the above object, the embossing key fixture of the automobile air conditioner compressor bent axle designed by this utility model, it includes base plate, base plate is provided with die holder, described die holder upper end is provided with the upper cavity of concave downward, the lower cavity upwards caved in it is provided with in the lower end of die holder, connected by through hole between upper cavity with lower cavity, it is provided with die and for fixing the fixing seat of die at recessed intracavity, described die is provided centrally with nib, surface configuration at nib has the projection matched with spline, aligns with nib center vertical in described through hole center；Upper cavity at die holder is provided with and limits the guide shaft set that bent axle moves at vertical direction, and described bent axle is then arranged in guide shaft set and through hole；Being provided with pressure head on bent axle, be provided with the limit for height block of hollow structure outside the upper cavity of die holder, being provided above and the cope match-plate pattern pressing equipment to be connected down at pressure head, the lower surface of cope match-plate pattern is provided with briquetting.
Technique scheme, cavity and lower cavity on being provided with on die holder, and it is provided with through hole between upper cavity and lower cavity, coordinate the fairlead of fovea superior intracavity to realize bent axle can only move by vertical direction simultaneously, act on cope match-plate pattern at hydraulic mechanism, cope match-plate pattern drives briquetting to move downward, thus pressure head is extruded, pressure head promotes axis body to move downward in fairlead and through hole, and align with the nib at die center in the end of axis body, and under press through can complete spline in journey compressing, its efficiency is high, process velocity is fast, and the location of bent axle axis body is convenient and simple.
As optimization, the center of base plate being provided with circular hole, be provided with a push rod in circular hole, the diameter of push rod is less than the diameter of bent axle spline place axis body, and push rod is positioned at the scope of bent axle spline place axis body.Being fixed with a sleeve pipe under the circular hole of base plate, the internal diameter of described sleeve pipe, less than the diameter of circular hole, is provided with knockout rod in sleeve pipe and extends in circular hole, and the diameter that knockout rod is in circular hole is more than its diameter in sleeve pipe, and knockout rod contacts cooperation with push rod.The design of said structure, after the axis body embossing key of bent axle completes, coordinates when being closely difficult to take out bent axle between spline and the projection in nib, can pass through coordinating between knockout rod with push rod, released by axis body, will not axis body be damaged.
The lower end of described pressure head coordinates with the upper end of bent axle, and pressure transmission is to the central axis of bent axle axis body.This structure can ensure that under press through in journey and axis body will not be damaged, and active force is uniform, and the stability in the course of processing is better.
The embossing key fixture of the automobile air conditioner compressor bent axle that this utility model is obtained, by the setting that the guide shaft of the through hole on die holder and fovea superior intracavity overlaps, it is achieved bent axle can only move at vertical direction, in its course of processing, precision is high, and without location, simple and convenient, good stability.
