Description

Regular polygon truning fixture
Technical field
The utility model relates to regular polygon Technology for Turning Machining field, specifically a kind of regular polygon truning fixture.
Background technology
Processing regular polygon axostylus axostyle part, conventional method is milling and planing operation, if adopt indexing mechanism to carry out regular polygon processing on this type of lathe, just relates to the factors such as indexing accuracy, intermittently-driving, the adjustment of calibration frock, cause working (machining) efficiency low, the defect such as precision is low.So be necessary to design a kind of efficient device for regular polygon turning.
Utility model content
Technical problem to be solved in the utility model is the efficient regular polygon truning fixture of one designing for above-mentioned needs of the prior art, uses the principle of fixed shaft gear train transmission, realizes polygonal turning processing.
The technical solution of the utility model is as follows:
A kind of regular polygon truning fixture, it is characterized in that: include coaxial mounted driving gear, lathe tool and driving wheel, coaxial mounted driven gear and chuck and lathe tailstock, between described driving and driven gear, be engaged with sloth wheel gear, on described chuck, clamping has workpiece, thimble on described lathe tailstock leans the center in workpiece end, described lathe tool is positioned at a side of workpiece, and nose part on lathe tool abuts in a side of workpiece.
Described regular polygon truning fixture, is characterized in that: described driving wheel adopts belt pulley.
Described regular polygon truning fixture, is characterized in that: the axial line distance between the radius sum of the radius of gyration of described lathe tool and workpiece and described driving and driven gear equates.
The beneficial effects of the utility model:
The utility model is simple in structure, is easy to realize, and uses the principle of fixed shaft gear train transmission, in the situation that precision allows, can realize the high-efficient cutting of polygon workpeace.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is in the utility model between lathe tool and workpiece, to be the point of a knife that obtains for 6 o'clock and the relevant path figure of workpiece by rotating ratio.
Detailed description of the invention
Referring to Fig. 1, a kind of regular polygon truning fixture, include coaxial mounted driving gear 1, lathe tool 8 and driving wheel 7, coaxial mounted driven gear 3 and chuck 9 and lathe tailstock 6, between driving and driven gear 1,3, be engaged with sloth wheel gear 2, on chuck 9, clamping has workpiece, it is undressed section 4 of the workpiece shown in Fig. 1 and workpiece processing sections 5, thimble on lathe tailstock 6 leans the center in workpiece end, lathe tool 8 is positioned at a side of workpiece, and nose part on lathe tool 8 abuts in a side of workpiece.
In the utility model, driving wheel 7 adopts belt pulley; Axial line distance between the radius sum of the radius of gyration of lathe tool 8 and workpiece and driving and driven gear 1,3 equates.
Lathe tool 8 is arranged on same axis with driving gear 1, and with driving gear 1 synchronous rotary; Gear driving gear 1 drives driven gear 3 to rotate by sloth wheel gear 2 simultaneously, and driven gear 3 is arranged on same axis with chuck 9, makes workpiece and driven gear 3 synchronous rotaries.According to drive connection, the direction of rotation of workpiece is identical with the direction of rotation of lathe tool 8, at cutting zone, realizes cutting movement in opposite directions between lathe tool 8 and workpiece.Use the knowledge analysis of theory of mechanics to draw, lathe tool 8 is bent polygon with respect to the movement locus of workpiece, in the scope allowing, can realize the efficient turning of polygon workpeace in error.
The utility model energy clamped one time and process multiple planes, is conducive to the Composite of processing, working (machining) efficiency has been had and significantly improve.The utility model has also been expanded the scope of turning preferably, and traditional turning machine can only be processed the surface of revolution, and the utility model can be used for the even more complicated profile of turning processing plane.What the utility model used is the principle of fixed shaft gear train transmission, implements simple.
When concrete turning, use motor to drive lathe power shaft to rotate by belt, lathe tool 8 rotates with power shaft, and its rotating speed is determined by motor speed and the gearratio with transmission.
When concrete turning, power shaft leads to the fixed shaft gear train drive output shaft rotation that driving gear 1, sloth wheel gear 2 and driven gear 3 form, and the rotating speed of output shaft is determined by the number of teeth relation of driving gear 1, sloth wheel gear 2 and driven gear 3.
When concrete turning, one end of workpiece is clamped in the chuck 9 being fixedly connected with output shaft, and the other end of workpiece withstands with the thimble on lathe tailstock 6, and workpiece is rotated together with output shaft, and rotating speed is identical with output shaft.
When concrete turning, in order realizing, the polygon of different edge number to be carried out to turning, can to utilize the method for aforesaid change motor speed and train gearratio, the rotating speed of input, output shaft is met the demands.
Adopting the polygon of the utility model processing is Curvilinear polygon, there is certain straightness error in its limit, the size of its straightness error also can be by adjusting lathe tool 8 and workpiece centre apart from realizing, as long as in error range, can make the working (machining) efficiency of this workpiece obtain unprecedented raising, in the utility model, without workpiece is carried out to calibration and multiple clamping.
As seen from Figure 2, the core of this track is bent hexagon 10.In the time that gearratio changes, can obtain the polygon workpeace of different edge number.
