Description
Technical field
This utility model belongs to field of fixtures, is specifically related to a kind of valve core of servo valve nozzle abrasive Flow polishing clamp.
Background technology
Servo valve is fine control element crucial in electrically-Hydrauservo System, its as a kind of precision element in Aero-Space and weapons field, as the fields such as satellite, carrier rocket, tank, infantry fighting vehicles, laser guided projectile and guided missile have a wide range of applications.Owing to servo valve baffle plate is less with nozzle gap, the degree of cooperation of baffle plate and nozzle also requires that more strict, so the processing stage of valve core of servo valve nozzle is the most difficult.But, abrasive Flow polishing technology preferably can carry out the work such as deburring, deburring, rounding to complex shape part or micro hole workpiece.Therefore, for preferably improving the polishing precision of valve core of servo valve nozzle, improving the jet performance of servo valve, we use abrasive Flow polishing technology.Due to after valve core of servo valve nozzle is carried out abrasive Flow polishing, sharp edge at valve core of servo valve spray nozzle front end nozzle requires to be destroyed, so when abrasive Flow polishes, needing that the valve core of servo valve nozzle polishing clamp carrying out abrasive Flow polishing is carried out clamping to fix, otherwise the abrasive Flow quality of finish of valve core of servo valve nozzle will be affected.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of valve core of servo valve nozzle abrasive Flow polishing clamp, and this fixture can effectively solve valve core of servo valve nozzle and can be fixed properly clamping during abrasive Flow Machining and ensure the problem that nozzle sharp edge is not ground destruction.
In order to reach it is above-mentioned purpose, a kind of valve core of servo valve nozzle abrasive Flow polishing clamp that this utility model provides illustrates as a example by processing 6 valve core of servo valve nozzles simultaneously, this fixture is mainly made up of upper end-fixture, intermediate holder and lower end fixture three part, and described upper end-fixture, intermediate holder and lower end fixture are oblate column type；Described upper end-fixture is provided with 6 ladder abrasive materials and enters the end construction consistent size of passage, passage lower end shape and valve core of servo valve nozzle, and upper end-fixture bottom is provided with 2 positioning boss；Intermediate holder upper end is provided with 6 charging apertures connecting upper end-fixture and the location shrinkage pool matched with positioning boss, inside is provided with and the valve core of servo valve identical die cavity of nozzle exterior physical dimension, lucky for valve core of servo valve nozzle can be put into, prevent it from moving in the course of processing and the sharp edge of spray nozzle front end is ground destruction, and in the middle part of die cavity, have the relief passage with loop configuration, the effective of the side opening to the valve core of servo valve nozzle face of cylinder can be realized process, prevent from crossing senior general's valve core of servo valve workpiece nozzle sharp edge due to pressure to destroy, intermediate holder lower end is provided with 6 small-sized discharging openings and 2 big discharging openings and 2 positioning boss；Fixture upper end, lower end is provided with the small-sized charging aperture in 6 corresponding with intermediate holder lower end and 2 big charging apertures and the hole, 2 location matched, it is provided with abrasive material inside the fixture of lower end and converges flow pass, the abrasive material convergence flow that the abrasive material that each several part flows out gathers fixture bottom, lower end is portalled, it is simple to collect.
There is annular groove the upper end of described upper end-fixture lower end, the top and bottom of intermediate holder and lower end fixture, equipped with rubber seal inside annular groove, prevents abrasive material from leaking.
The beneficial effects of the utility model are: this utility model is made up of upper end-fixture, intermediate holder, lower end fixture three part, utilize boss to install location between three part fixtures, can prevent from occurring between three part fixtures relative displacement.Fixture removes and installs conveniently, the planform of valve core of servo valve nozzle it is arranged to inside fixture, the most both the inner passage of valve core of servo valve nozzle effectively can be processed, valve core of servo valve spray nozzle front end sharp edge can be prevented again to be destroyed, and this fixture also can be extended to polish the fixture of single or multiple valve core of servo valve nozzle as required simultaneously.
