Abstract
A kind of universal fixture improving shaft gear part installation accuracy, including disk, screw, the disk is arranged on the workbench of gear machining apparatus, upper and lower surface is parallel, upper surface is provided with the T-slot being arranged by center of circle radial equipartition, and the T-slot is 8, and 8 uniformly distributed threaded holes are provided on disk, 8 threaded hole centers and disc centre are apart from identical, and 8 threaded holes are located among two adjacent T-slots；Screw is 8, is fitted in the threaded hole on disk, and the screw length is greater than the thickness of disk, and the bottom of screw is contacted with workbench.The utility model can directly inherit itself precision of two benchmark of part, and when centering preferentially guarantees the precision close to working position benchmark, realize teeth directional and bounce precision within 0.01mm.
Description
Technical field
The utility model relates to a kind of mounting tool, especially a kind of general work for improving shaft gear part installation accuracy
Dress.
Background technique
The required precision of aviation precision gear teeth portion is high, and gear shaping precision is up to 5 grades, and teeth directional tolerance is required on the left side 0.01mm
The right side, reaches as high as 0.006mm, and spline reaches as high as 0.015mm to joint benchmark run-out tolerance.To teeth directional, bounce precision
In guarantee, the clamping of part benchmark, centering precision are particularly critical, especially shaft gear class part, due to joint benchmark at a distance of compared with
Far, joint benchmark centering precision is insufficient, and teeth directional, bounce precision not can guarantee yet.Currently used mode is by greatly improving
Part benchmark accuracy and by clearance gauge class tool auxiliary clamping, centering, improves itself precision of part benchmark and makes difficulty of processing
Increase, economic cost it is excessively high, large labor intensity, low efficiency when clearance gauge class tool auxiliary clamping, and be not easy to reach degree of precision.Such as
A certain aviation precision gear part, joint benchmark itself circularity require 0.005mm, and concentricity requires Φ 0.005mm, and use is dedicated
Gear-shaping clamp clamping parts, by parts fixation axial locating surface with combine benchmark between verticality influenced, will lead to part revolution in
Heart line and machine tool chief axis are not parallel, this, which just needs to adjust part, keeps it vertical.Using clearance gauge, road paper (with a thickness of the one of 0.01mm
Kind of industrial paper) pad in part or gear-shaping clamp low spot, due to clearance gauge, road paper itself thickness between be divided into 0.01mm, adjust small
Difficulty is larger when 0.01mm error, and occurs for height interval, the part of continuous low spot, and the difficulty of leveling is very big.It presses
Method centering part is planted like this, and correct error is at least 0.005mm, in addition part itself trueness error 0.005mm, real centering
Error is 0.01mm or more, and for the part within teeth directional 0.01mm, precision almost not can guarantee.
Summary of the invention
The utility model aim is to provide a kind of universal fixture, it is ensured that the clamping of gear part benchmark, centering precision
It is required that achieving the effect that labor intensity, high-efficient.
The technical solution of the utility model is, the universal fixture for improving shaft gear part installation accuracy includes disk, screw,
The disk is arranged on the workbench of gear machining apparatus, and upper and lower surface is parallel, and upper surface is provided with radially equal by the center of circle
The T-slot of cloth setting, the T-slot are 8, and 8 uniformly distributed threaded holes, 8 threaded holes are provided on disk
Center and disc centre are apart from identical, and 8 threaded holes are located among two adjacent T-slots；Screw is 8, is coupled
In threaded hole on disk, the screw length is greater than the thickness of disk, and the bottom of screw is contacted with workbench.
When the utility model is used, tooling is fixed on platen, in the upper surface of tooling installation gear shaping folder
Tool, or it is mounted directly part.When checking that part joint benchmark discovery part side is lower, when part is oblique to the inclination, pass through
The bolt angularly located is screwed, contacts bolt lower surface with workbench, which is jacked up slightly, reduces part inclination, leads to
It crosses many places bolt to be used cooperatively, guarantees that different conditions part reaches vertical state.It is past since normal part itself inclination is smaller
It can reach preferable centering state toward the position is jacked up 0.01mm or so by bolt, so small fixture deformation also will not
Generate other negative effects.
Original method is by using clearance gauge class tool auxiliary transverse alignment, alignment time at least 30 minutes/part, labor intensity when centering
Greatly, part out of the ordinary is looked for not just.And per part alignment time of the present invention foreshortens to 5 minutes/part, labor intensity is extremely low, looks for
Positive precision greatly improves.Meanwhile original method is to guarantee that clamping Central of the parts line when on gear-shaping clamp is parallel with machine tool chief axis,
Need to formulate process route, guarantee parts fixation axial locating surface with combine reference vehicular degree, due to process increase, part is processed
Cost increases.Parts fixation axial locating surface is required with reference vehicular degree is combined using reducing after this tooling, to the verticality
Caused correct error is finely adjusted by this tooling, shortens process flow and difficulty of processing, reduces economic cost.Use this work
Dress can be achieved the adjustment of any number size by finely tuning, realize that Central of the parts line is parallel with machine tool chief axis, centering precision can be direct
Itself precision of two benchmark of part is inherited, according to different design of part, when centering, preferentially guarantees the precision close to working position benchmark,
Really influence teeth directional, beat precision error within 0.005mm, under the influence of not considering other factors, teeth directional and bounce
Precision is can be controlled within 0.01mm.
