Description
Technical field
The present invention relates to a kind of cam axial trough Machining of Curved Surface special fixture, belong to cam axial trough Machining of Curved Surface equipment technical field.
Background technology
The processing of cam axial trough curved surface owing to being the trial-production of product, small lot batch manufacture, typically use vertical machining center, need the clamping tooling fixture that Aided design is special.This processing method is time-consuming at camshaft parts fixation, and the process-cycle is long, and cost puts into relatively big, and labor productivity is low, and inadaptable turning criticizes large batch of production, and part positions also inaccuracy, and quality is unstable.
Summary of the invention
There is technical problem for solving prior art, the invention provides a kind of simple in construction, easy to use, it is possible to be directly anchored on milling machine, clamping processing ease, the cam axial trough Machining of Curved Surface special fixture that production efficiency is high.
For achieving the above object, the technical solution adopted in the present invention is cam axial trough Machining of Curved Surface special fixture, including base, the two ends of described base are provided with bearing, it is slidably fitted with axle sleeve on one end bearing, it is provided with rotating shaft on other end bearing, it is fixed with master cam on described axle sleeve, it is slidably fitted with scroll chuck in described rotating shaft, it is further fixed on straight pin on described base, on described straight pin, bearing is installed, described bearing contacts with master cam, it is provided with pipe bending cylinder on the bearing of mounting sleeve, the piston rod of described pipe bending cylinder is used for promoting master cam；The drive mechanism rotated for drive shaft it is provided with in described rotating shaft.
Preferably, described base is bolted on milling machine.
Preferably, described drive mechanism includes gear, tooth bar and chute, described gear is arranged on the end of rotating shaft, the lower section of described gear is provided with chute, described chute is fixed on base, being slidably fitted with tooth bar in chute, described rack and pinion is meshed, and described tooth bar is provided with the driving oil cylinder for driving tooth bar to move.
Compared with prior art, the present invention has following technical effect that present configuration is simple, easy to use, directly secure fixtures on plain-milling machine, being simple to manufacture of part, clamping processing ease, need not Programming Design, single-piece manufacturing time shortens, and manufacturing cost is greatly reduced；And it is simple to manufacture operation, production efficiency is high, it is possible to meets and produces in enormous quantities；Positioning and clamping precision is high, and workmanship is stable, good product consistency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, cam axial trough Machining of Curved Surface special fixture, including base 1, the two ends of base 1 are provided with bearing 2, axle sleeve 3 it is slidably fitted with on one end bearing, rotating shaft 4 it is provided with on other end bearing, master cam 5 it is fixed with on axle sleeve 3, scroll chuck 6 it is slidably fitted with in rotating shaft 4, scroll chuck is fixed in rotating shaft by bonded, ensure that scroll chuck can move axially, and synchronous rotating shaft rotates, straight pin 7 it is further fixed on base 1, bearing 8 is installed on straight pin 7, bearing 8 contacts with master cam 5, it is provided with pipe bending cylinder 9 on the bearing 3 of mounting sleeve, the piston rod of pipe bending cylinder 9 is used for promoting master cam 5；The drive mechanism rotated for drive shaft it is provided with in rotating shaft 4.
Wherein, drive mechanism includes gear 11, tooth bar 12 and chute 13, gear 11 is arranged on the end of rotating shaft 4, the lower section of gear 11 is provided with chute 13, chute 13 is fixed on base 1, being slidably fitted with tooth bar 12 in chute 13, tooth bar 12 is meshed with gear 11, and tooth bar 12 is provided with the driving oil cylinder for driving tooth bar to move.
In use, directly base 1 is fixed on milling machine by bolt 10, camshaft to be processed is inserted in axle sleeve, and stretches out outside axle sleeve, fixed by scroll chuck, then fix lock-screw on axle sleeve, axle sleeve and camshaft are fixed.Pipe bending cylinder stretches out, the piston rod making pipe bending cylinder withstands one end of master cam, master cam drives axle sleeve, scroll chuck to move, the master cam other end contacts with bearing, the end face contacted with bearing is provided with difform projection, specifically can carry out selecting design according to the curved surface of reality processing, thus change the movement locus of master cam, it is achieved the processing of different curve groove.Tooth bar moves under the effect driving oil cylinder, drives pinion rotation, thus controls cam axle to be processed, and simultaneously under the effect of master cam, movement locus is continually changing, thus is processed into axial trough curved surface.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, all should wrap within the scope of the present invention.
