Abstract
The utility model discloses a combined clutch pulling-out cutter, which comprises a clutch pulling-out cutter (3) and a special clamp (4). The special clamp (4) is cylindrical, the inner surface of the special clamp (4) is uniformly provided with pulling-out cutter positioning surfaces (7) with the number identical to the number of external splines of a clutch (2), and the clutch pulling-out cutter (3) is arranged on the pulling-out cutter positioning surfaces of the special clamp (4) and is fixed through screws (5). The utility model has the beneficial effects that the maximum production potential of the combined clutch pulling-out cutter can be developed through broaching, the clutch with high-precision external splines, good size consistency and relatively uniform processing stress can be processed by adopting the characteristics of a broaching machine such as high efficiency and high precision, the clutch production efficiency is increased, and the production cost is reduced.
Description
Technical field
The utility model relates to process tool, particularly a kind of clutch combination broach for external bracing.
Background technology
At present, the method for processing clutch mainly is to adopt form cutter to carry out Milling Process on milling machine.But because the Milling Process precision is low, surface roughness value is big, and one-pass can only spline tooth of milling external splines, and production efficiency is low, is not suitable for producing in enormous quantities.
And adopt the line cutting special process, and though easy to process, efficient is lower, the processing cost height does not satisfy the economy requirement of modern processing enterprise.
The utility model content
The purpose of this utility model promptly is to overcome the shortcoming of prior art, a kind of clutch combination broach for external bracing is provided, make the maximum productive potentialities of its performance by broaching processing, utilize high efficiency, the high accuracy characteristics of broaching machine simultaneously, can process external splines precision height, good, the uniform relatively clutch of machining stress of dimensional uniformity, also can improve the serviceability of clutch simultaneously.
The purpose of this utility model is achieved through the following technical solutions: clutch combination broach for external bracing, it comprises clutch broach for external bracing and special fixture, special fixture is a tubular, the uniform broaching tool locating surface that equates with the external splines bond number of clutch of the inner surface of special fixture, the clutch broach for external bracing is installed on the concrete broaching tool locating surface of exclusive clamps and by screw and fixes.
Described clutch broach for external bracing is elongated shape, and the cross sectional shape of clutch broach for external bracing is trapezoidal, and trapezoidal dual-side bends inwards into two angles, angle and clutch coupling.
Cutting teeth portion on the described clutch broach for external bracing has rise per tooth.
The beneficial effects of the utility model show: high efficiency, the high accuracy characteristics of processing and utilize broaching machine by broaching, improved the serviceability of clutch, surface quality is good, the workpiece size high conformity, and has improved the production efficiency of clutch, has saved production cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but that protection domain is not limited to is described.
As Fig. 1, Fig. 4, clutch combination broach for external bracing, it comprises clutch broach for external bracing 3 and special fixture 4, special fixture 4 is a tubular, the uniform broaching tool locating surface 7 that equates with the external splines bond number of clutch 2 of the inner surface of special fixture 4, special fixture 4 itself has symmetry, perpendicularity height, characteristics that the five equilibrium error is little, and clutch broach for external bracing 3 is installed on the broaching tool locating surface 7 of exclusive clamps concrete 4 and is fixing by screw 5.
As Fig. 2, Fig. 3, described clutch broach for external bracing 3 is elongated shape, and the cross sectional shape of clutch broach for external bracing 3 is trapezoidal, and trapezoidal dual-side bends inwards into two angles, angle and clutch 2 couplings.
Cutting teeth portion 8 on the described clutch broach for external bracing 3 has rise per tooth, and by the tooth cutting, the vertical broaching machine depression bar promotes clutch broach length stroke of workpiece operation to the workpiece layering.
Use of the present utility model is as follows:
The first step is installed on clutch broach for external bracing 3 on the concrete 4 inside broach locating surfaces of exclusive clamps, because that special fixture 4 itself has a symmetry, perpendicularity height, five equilibrium error is little, the clutch 2 that processes can guarantee its dimensional accuracy fully;
Second goes on foot, and special fixture 4 is lifted on the broaching machine workbench 6 installs, debug and fix;
The 3rd step, start vertical broaching machine, broaching machine depression bar 1 moves vertically downward, broaching machine depression bar 1 passes to clutch 2 with pressure, and clutch 2 promotes lower edge special fixture 4 motion vertically downward in the thrust of depression bar, and 3 pairs of clutches 2 of clutch broach for external bracing are promptly realized the machining of external splines, 3 designs of clutch broach for external bracing have rise per tooth, by the tooth cutting, the vertical broaching machine depression bar promotes clutch broach length stroke of clutch 2 operations, promptly finishes the processing to a clutch 2 to clutch 2 layerings;
In the 4th step, broaching machine depression bar 1 is back to original position, and next clutch 2 processing are prepared.
Claims (3)
