Abstract
The invention provides a clamp for machining of eccentric shafts. The clamp for machining of the eccentric shafts comprises an eccentric mandrel, an eccentric base and spring chucks, wherein the eccentric base is connected with the eccentric mandrel in a sliding fit mode, the spring chucks are installed on the eccentric base, an installation hole is formed in the center of the eccentric base, the installation hole is internally provided with an elastic installation part connected with the spring chucks, and the diameter of the section of an opening of the installation hole is smaller than that of the section of the elastic installation part. The clamp for machining of the eccentric shafts can be applied to an ordinary lathe to machine the eccentric shafts, the defects of a traditional eccentric shaft machining process are overcome, and the eccentric shafts of different sizes can be machined by replacing the spring chucks, of different specifications, on the eccentric base. The clamp for machining of the eccentric shafts is simple in structure and only needs to be installed once when used, the eccentric shafts do not need to be corrected or adjusted, machining efficiency is high, universality is good, and the clamp is suitable for batch machining of the eccentric shafts.
Description
Technical field
The present invention relates to fixture, more specifically, relate to the special fixture of processing eccentric shaft on a kind of engine lathe.
Background technology
To be a kind of cylindrical parallel with the axis of cylindrical and the workpiece that do not overlap for eccentric shaft.In order to facilitate the centre-to-centre spacing between regulating shaft and axle, eccentric shaft is used in the transmission of planar linkage mechanism V-belt conventionally.Conventionally, in frame for movement setting-up eccentricity axle be exactly by it effect of inertia and be unlikely to machine lock machine for example, be arranged on eccentric shaft the running that drives foot-propelled driving wheel on domestic sewing machine running to dead-centre position.
Engine lathe can only be processed concentric shafts, and the function of not processing eccentric shaft will be processed eccentric shaft on engine lathe, and specific fixture must be installed.The method of tradition processing eccentric shaft is on lathe, to add chuck, the one end of clamping axle with chuck, and operating personnel, by the claw of mobile two symmetries, determine the offset of eccentric shaft to the side-play amount of lathe pivot according to symmetrical claw.This method need to be proofreaied and correct repeatedly, and cannot reach higher precision and tolerance, and therefore, production efficiency is low and crudy is poor, is not suitable for batch machining eccentric shaft.
Summary of the invention
For above-mentioned defect of the prior art, the invention provides that a kind of working (machining) efficiency is high, processing versatility good eccentric shaft processing clamp.
The invention provides a kind of eccentric shaft processing clamp, the eccentric mounting that comprises eccentric axle, connect with the sliding accessory of described eccentric axle and be arranged on the spring chuck on described eccentric mounting, described eccentric mounting center is provided with installing hole, the elastic mounting part linking together with described spring chuck is housed in described installing hole, and the opening section diameter of described installing hole is less than the diameter of section of described elastic mounting part.
In a preferred embodiment of the present invention, further comprise, between the periphery of described elastic mounting part and the inwall of described installing hole, be provided with resilient sleeve.
In a preferred embodiment of the present invention, further comprise, the center line of described installing hole and described spring chuck on same straight line, the pivot that described center line is lathe.
In a preferred embodiment of the present invention, further comprise, described spring chuck is locked on described eccentric mounting by tight loop.
In a preferred embodiment of the present invention, further comprise, described eccentric mounting is connected in described eccentric axle by screw in compression.
In a preferred embodiment of the present invention, further comprise, the periphery of described eccentric axle is arranged on lathe by Mohs outer cone.
In a preferred embodiment of the present invention, further comprise, the outer ring of described eccentric mounting is provided with scale.
The invention solves deficiency of the prior art, reach following beneficial effect: eccentric shaft processing clamp of the present invention can be applicable to and on engine lathe, processes eccentric shaft, made up the deficiency of the processing technology of traditional eccentric shaft, and can, by changing the spring chuck of different size on eccentric mounting, just can process the eccentric shaft of different sizes; This fixture simple in structure, only need install once during use, and workpiece is adjusted without proofreading and correct, and working (machining) efficiency is high, versatility good, the batch machining of suitable eccentric shaft.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Wherein, 1-Mohs outer cone, the eccentric axle of 2-, 3-resilient sleeve, 4-screw, 5-eccentric mounting, 6-elastic mounting part, 7-tight loop, 8-spring chuck, 9-center line, 10-installing hole.
The specific embodiment
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, the invention provides a kind of eccentric shaft processing clamp, mainly comprise eccentric axle 2, eccentric mounting 5 and spring chuck 8 three parts.Wherein, eccentric mounting 5 is connected together with the sliding accessory of described eccentric axle 2, and above-mentioned spring chuck 8 is arranged on described eccentric mounting 5, and more specifically, spring chuck 8 is locked in described eccentric mounting 5 by tight loop 7.
The above eccentric mounting 5 center is provided with installing hole 10, the elastic mounting part 6 linking together with described spring chuck 8 is housed in described installing hole 10, the opening section diameter of described installing hole 10 is less than the diameter of section of described elastic mounting part 6, after utility elastic mounting part 6 elasticity own snap in installing hole 10 like this, elastic mounting part 6 is difficult for dropping out installing hole 10, and be provided with resilient sleeve 3 between the periphery of described elastic mounting part 6 and the inwall of described installing hole 10, this resilient sleeve 3 be also play make elastic mounting part 6 more convenient and engaging be arranged in installing hole 10, being about to spring chuck 8 is better arranged on eccentric mounting 5.Like this, described installing hole 10 with the center line 9 of described spring chuck 8 on same straight line, the pivot that described center line 9 is lathe.
In an embodiment of the present invention, on the outer ring of stating eccentric mounting 5, be carved with scale, when fixture is installed, aim at after the zero line on scale, first by a tight loop 7, above-mentioned spring chuck 8 compact locks are fixed on above-mentioned eccentric mounting 5, in actual process, by changing the spring chuck 8 of different size, can process the eccentric shaft of different sizes; State eccentric mounting 5 and compressed and be connected in above-mentioned eccentric axle 2 by screw 4, then the periphery of eccentric axle 2 is arranged on lathe by Mohs outer cone 1, has completed like this installation of this fixture.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
