Abstract
The invention discloses an in-shaft spline and outer circle coaxiality machining and positioning device and a process method. According to a traditional method, the outer circles of workpieces are clamped through a chuck, and then the end faces are pressed; due to the fact that the sizes of the outer circles and the axial lengths of the workpieces are different, some workpieces can not be directly clamped and can not be positioned until multiple gaskets are arranged at appropriate positions, positioning standards and alignment standards of the workpieces can not be unified, the tool rigidity is influenced when the axial sizes are large, and the machining accuracy is low. The in-shaft spline and outer circle coaxiality machining and positioning device is composed of a jig body and a gasket. Four U-shaped grooves which are evenly distributed are formed in the bottom of the jig body. The jig body is fixed to a working table when T-shaped bolts penetrate the U-shaped grooves. Four T-shaped grooves which are evenly distributed are formed in the upper end of the jig body. Workpieces are fixed when T-shaped bolts penetrate the T-shaped grooves. The gasket is placed on the jig body, and it must be ensured that two planes are parallel. The workpieces are placed on the gasket. The gasket is selected according to the workpiece positioning outer circle size. According to the designed positioning device, the purpose of unifying the in-shaft spline and outer circle process standards is achieved, positioning is stable, and the machining accuracy is high.
Description
Technical field
The present invention relates to Machining Technology field, specifically a kind of axle internal spline and outer circles processing and positioning device and process.
Background technology
At present, in the prior art, the processing of reducer output shaft internal spline and outer circles, traditional processing technology is: the stifled-centering-fine turning outer circle-cylindrical grinding of rough turn cylindrical, end face-mill splined hole-join-go blocks up-insert internal spline.Now internal splined hole center with join stifled after institute's processing excircles center not on a center line.Reason is exactly center after grinding out is not a benchmark with joining stifled, centering, turning, cylindrical grinding center, so cause internal spline and outer circles not to ensure.Original-pack card mode uses scroll chuck to block excircle of workpiece, then pushes down end face with pressing plate, but excircle of workpiece and axial length size difference, some workpiece can not direct clamping, can only configure multiple packing ring again and locate to correct position, complex operation, location is unstable, centering difficulty.Caused Workpiece fixing benchmark and centering unifying datum not, and axial dimension length affects cutter rigidity, reduces machining accuracy.When traditional processing technology and the mode that is installed not only make processing internal spline, positioning datum and centering benchmark are not unified all the time, and location is unstable, be installed, centering is unreasonable, cause the axiality that cannot ensure axle internal spline and cylindrical, affect processing precision of products, mainly shorten product service life.This processing method can not meet present high quality of products designing requirement far away.
Summary of the invention
The object of the invention is, a kind of axle internal spline and outer circles processing and positioning device and process is provided for the problems referred to above, redesign Working piece positioning device and new technological method for processing, thoroughly solve positioning datum and centering benchmark problem, ensure that the processing of axle internal spline and outer circles.
The technical solution adopted for the present invention to solve the technical problems is, axle internal spline and outer circles processing and positioning device are made up of carcass, packing ring, 4 are had to be uniformly distributed U-type groove bottom carcass, wear T-shaped bolt and workbench is fixed, there are 4 equally distributed T-slot upper end, wears T-shaped bolt fixation workpiece; Packing ring to be placed on carcass and must to ensure that two planes are parallel; Workpiece is placed on packing ring; Because Workpiece fixing excircle dimension is different, so the packing ring of multiple different size (hole and cylindrical) can be designed during design, select a packing ring according to Workpiece fixing excircle dimension.
Axle internal spline is completed and outer circles is processed according to following steps:
Step one, rough turn axle left end end face, cylindrical, hole;
Step 2, rough turn axle right-hand member end face, cylindrical, centering;
Step 3, axle left end is joined stifled, centering;
Step 4, finish turning axle left end cylindrical and axle right-hand member cylindrical;
Step 5, mill axle left end cylindrical, by face grinding A; Mill axle right-hand member cylindrical, by face grinding B;
Step 6, goes to block up;
Step 7, mill axle left end internal splined hole, by face grinding E (centering left end cylindrical and end face A);
Step 8, is inserted into internal spline;
Be placed on by workpiece on packing ring and locate with end face B, centering left end cylindrical and E face, packing ring is placed on carcass, can complete the processing of workpiece.Ensure that the unification of axle class internal spline and Excircle machining positioning datum and centering benchmark, improve machining accuracy.
The invention has the beneficial effects as follows, positioning datum and the centering benchmark of splined hole and cylindrical has been unified from process, ensure that flower arrangement key time positioning datum and centering benchmark be same benchmark, and devise positioner, the problem of instability, benchmark disunity and machine tool spindle rigidity deficiency is located when solving machining shaft internal spline, improve the axiality machining accuracy of internal spline and cylindrical, be installed, centering is more reasonable.This positioner is simple to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is the manuscript of finish turning of the present invention, cylindrical grinding;
Fig. 2 be the present invention arrange flowers key time work sheet.
In figure: 1 is carcass, 2 is packing rings, and 3 is workpiece, and A, B, E are axial end.
A, B are the end face by mill after cylindrical grinding.
Detailed description of the invention:
From Fig. 1 ~ 2,
Design and produce a positioning stablity, easy to operate positioner.The problem of unstable, the benchmark disunity in location and machine tool spindle rigidity deficiency when which solves machining shaft internal spline, improves machining accuracy, is installed, centering is more reasonable.This device is made up of carcass, packing ring.
Mill splined hole operation is changed to cylindrical grinding aft-loaded airfoil, and mill associated end face must be leaned on during cylindrical grinding, when grinding splined hole so just can centering cylindrical grinding and lean on face grinding, guarantee splined hole and the same center of cylindrical.Ensure that the procedure of processing of axle internal spline and outer circles is as follows:
The processing of axle internal spline and outer circles is completed according to following steps:
Step one, rough turn axle left end end face, cylindrical, hole:
Step 2, rough turn axle right-hand member end face, cylindrical, centering;
Step 3, axle left end is joined stifled, centering;
Step 4, finish turning axle left end cylindrical and axle right-hand member cylindrical;
Step 5, mill axle left end cylindrical, by face grinding A; Mill axle lower end cylindrical, by face grinding B;
Step 6, goes to block up;
Step 7, mill axle left end internal splined hole, by face grinding E (centering left end cylindrical and end face A);
Step 8, is inserted into internal spline.
Put by workpiece 3 and locate with end face B on the positioning device, centering left end cylindrical and E face, penetrate T-shaped bolt from carcass T-slot, and with pressing plate workpiece pressing A face, fixation workpiece, can complete the processing of workpiece.
