Description

For the axial tightening formula fixing means of knuckle pan portion Compound Machining
Technical field
The present invention relates to knuckle processing technique field, more particularly to a kind of axle for knuckle pan portion Compound Machining To tension-type fixing means.
Background technology
Knuckle is one of major part on steering axle of automobile, and vehicle steadily can be made to travel and sensitive transmission traveling side To the function of knuckle is subject to automotive front load, supports and drive front-wheel to be rotated around stub and make motor turning.Knuckle Including bar portion, ring flange and fork, when ring flange and fork is processed, traditionally generally use horizontal Machining centers and utilize fixture It is pressed on pan portion front(Near the one side of fork)So as to fixed workpiece, the method is not suitable in the less steering of locating surface Section, and pan portion Facad structure is complicated, so as to cause considerable hurdle to regioselective face and stationary positioned face.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, and provide a kind of for knuckle pan portion Compound Machining Axial tightening formula fixing means, it tenses workpiece using knuckle shaft end screw thread, product is stressed equilibrium, so as to ensure to produce The stabilization of the quality of product, and clamp structure is more simple.
The technical solution adopted for the present invention to solve the technical problems is:A kind of axle for knuckle pan portion Compound Machining To tension-type fixing means, to knuckle pan portion near the side locating and machining face of bar portion, the locating surface is to surround bar portion axis Ring surface, then bar portion away from pan portion one end process locking screw, secure fixtures on the workbench of Digit Control Machine Tool, The fixture is horizontally disposed neck bush, sleeve, and bar portion is sequentially passed through into neck bush, sleeve, locking nut, then wears alignment pin Crossing pan portion insertion fixture prevents knuckle from rotating, and finally by locking nut screwing, knuckle is tensed on fixture vertically.
Further, the area of the locating surface is not less than 80cm2
Further, the locating surface is for planar annular or by multiple parallel plane staggereds, the end of the neck bush Face shape is corresponding with the locating surface.
Further, the sleeve includes multiple sleeves that the length that can be selected is not waited
The beneficial effects of the invention are as follows:A kind of axial tightening formula fixing means for knuckle pan portion Compound Machining, first to turning To the side locating and machining face of the section close bar portion of pan portion, the locating surface is the ring surface for surrounding bar portion axis, then remote in bar portion One end processing locking screw in separation disc portion, secures fixtures on the workbench of Digit Control Machine Tool, and the fixture is horizontally disposed axle journal Set, sleeve, neck bush, sleeve, locking nut are sequentially passed through by bar portion, and alignment pin then is inserted into the anti-rotation stop of fixture through pan portion Rotated to section, finally by locking nut screwing, knuckle is tensed on fixture vertically, this method utilizes knuckle shaft end spiral shell Line tenses workpiece, product is stressed equilibrium, so that ensure that the stable and fixture parts of the quality of product reduce half, Structure is more simple.
Brief description of the drawings
Fig. 1 is the signal when axial tightening formula fixing means for knuckle pan portion Compound Machining of the invention is used Figure.
Description of reference numerals:
1 --- pan portion 2 --- bar portion
3 --- locating surface 4 --- locking screws
5 --- neck bush 6 --- sleeves
7 --- locking nut 8 --- forks.
Specific embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not reality of the invention Apply scope limited to this.
As shown in figure 1, the axial tightening formula fixing means of the Compound Machining of pan portion 1 for knuckle of the present embodiment is: To knuckle pan portion 1 near the side locating and machining face 3 of bar portion 2, the locating surface 3 is the ring surface for surrounding the axis of bar portion 2, then Locking screw 4 is processed away from one end of pan portion 1, it is necessary to illustrate, according to the structure design of knuckle, bar in bar portion 2 The end of portion 2 requires machining for screw thread in itself, therefore, the locking screw 4 processed in this method is the design according to knuckle It is required that and rough machined screw thread, need to be processed further locking screw 4 in knuckle subsequent processing operations so that its accord with The structure design of knuckle is closed, therefore this method is alternatively carried out the operation that bar portion 2 is processed in advance, and utilize the work The screw thread of sequence processing, so as to reduce procedure of processing, reduces cost as locking screw 4.Explanation is needed also exist for, is turned to Section can be processed in forging process to locating surface 3, that is, the requirement to locating surface 3 is considered when designing forging mold, so that So that forging blank has the locating surface 3, locating surface 3 is suitably repaired again according to forging situation.
After processing locking screw 4, secure fixtures on the workbench of Digit Control Machine Tool, the fixture is horizontally disposed neck bush 5th, sleeve 6, neck bush 5 be in order to knuckle carry out be oriented to and radially it is spacing, by bar portion 2 sequentially pass through neck bush 5, sleeve 6, Locking nut 7, then by alignment pin(Do not drawn in figure)Prevent knuckle from rotating through the insertion fixture of pan portion 1, finally will lock Tight nut 7 is tightened, and knuckle is tensed on fixture vertically, and then the pan portion 1 of knuckle, fork 8 can be processed.
Preferably, the area of the locating surface 3 is not less than 80cm2, when the area is too small, it is unfavorable for positioning, it is also possible to Impression is formed on workpiece.
Preferably, the locating surface 3 is for planar annular or by multiple parallel plane staggereds, the end of the neck bush 5 Face shape is corresponding with the locating surface 3, so as to reduce the requirement to locating surface 3 so that the method is easier to realize.
Preferably, the sleeve 6 includes multiple sleeves 6 that length is not waited, and can according to circumstances select.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected The limitation of scope is protected, although being explained to the present invention with reference to preferred embodiment, one of ordinary skill in the art should Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention Matter and scope.
