Abstract

The utility model specifically discloses a special clamp for a comb dent clamping type numerical control spline shaft milling machine, which solves the problems that a conventional clamp for the numerical control spline shaft milling machine has inaccuracy for positioning, higher rejection rate and further worse universality. The special clamp comprises a sleeve-shaped base, which is fixed on a main shaft of a machine tool; a positioning sleeve which is sheathed in the base is fixed at the right end of the base; a bolt and a center are distributed at the left part and the right part in the positioning sleeve; a spring is arranged between the bolt and the center; further, a nut fixed with the positioning sleeve is screwed on the bolt; and the right end surface of the positioning sleeve is provided with comb dents. For the special clamp, the universality of the clamp is improved, the clamp is simple and quick to replace, the replacement time is greatly decreased, the production efficiency is drastically improved, the abnormal wear of the machine tool and the clamp is avoided, furthermore, the size of a spline, the effective length of the spline and the radial runout of a gear ring of the spline are controlled quite well, and the stability of processing quality is guaranteed; and the production efficiency is increased by 3 times, the rejection rate in a machining procedure is decreased by 50%, the service life of the machine tool and the clamp is increased by 20%, and the kinds of products which can be machined are increased by 60%.

Description

Broach clamped-in style numerical control spline milling machine special fixture
Technical field
The utility model relates to numerical control spline milling machine servicing unit, is specially a kind of broach clamped-in style numerical control spline milling machine special fixture.
Background technology
At present the numerical control spline milling machine adopts the spring housing clamping mode with anchor clamps, because excircle of workpiece causes with center hole is not of uniform size, causes and locatees inaccurate, insufficient clamping force; Cause the size and the spline circular runout of processing work unstable, percent defective is high, and existing anchor clamps use spring housing to clamp; Can only clamp the cylindrical in the certain limit; And it is cumbersome to change spring housing, has caused the unicity of existing anchor clamps processing parts kind, the versatility extreme difference.
Summary of the invention
There is the problem that the location is inaccurate, percent defective is higher and versatility is relatively poor in order to solve existing numerical control spline milling machine in the utility model with anchor clamps, and a kind of broach clamped-in style numerical control spline milling machine special fixture is provided.
The utility model is to adopt following technical scheme to realize: broach clamped-in style numerical control spline milling machine special fixture; Comprise the shell-like base that is fixed on the machine tool chief axis; The base right-hand member is fixed with cover positioning sleeve within it, is distributed with bolt and top about in the positioning sleeve, bolt and top between be provided with spring; And be screwed with on the bolt with positioning sleeve and be fixed with nut, the right side of positioning sleeve is provided with broach.During use, after the rotation nut is adjusted top pressure, be installed on the lathe, again part to be processed put into lathe; The part central aperture is top, and the lathe back centre stretches out, and utilizes back centre pressure; Top withdrawal, part end face cooperates with positioning sleeve right side broach, plays the effect to the workpiece clamping and positioning; Accurately locate the position of milling spline, error reduces, and has overcome existing numerical control spline milling machine and has had the problem that the location is inaccurate, percent defective is higher and versatility is relatively poor with anchor clamps.
The utility model uses through broach positioning sleeve and top mutual combination; Improved the versatility of anchor clamps, changed the anchor clamps simple and fast, greatly reduced and change the product time; Significantly improved production efficiency; Avoided the heel and toe wear of lathe and anchor clamps, and better controlled spline size, spline effective length and spline gear directly jump, guaranteed the stability of crudy; 3 times of improving productivity, the percent defective of manufacturing procedure reduces by 50%, and improved 20% the service life of lathe and anchor clamps, but the converted products kind has increased by 60%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-base, the 2-positioning sleeve, 3-is top, 4-spring, 5-bolt, 6-nut, 7-screw.
The specific embodiment
Broach clamped-in style numerical control spline milling machine special fixture; Comprise the shell-like base 1 that is fixed on the machine tool chief axis; Base 1 right-hand member is fixed with cover positioning sleeve 2 within it, is distributed with bolt 5 about in the positioning sleeve 2 with top 3, is provided with spring 4 between the bolt 5 and top 3; And be screwed with on the bolt 5 with positioning sleeve 2 and be fixed with nut 6, the right side of positioning sleeve 2 is provided with broach.In the practical implementation process, fixing between positioning sleeve 2 and the base 1 through screw 7.
