Abstract
The invention provides a manufacturing method of a sprocket and belongs to the technical field of metal processing. According to the technical scheme, an indexable right-angled shoulder milling tool is used for rough machining, a rough machining allowance 1mm is provided, the radius of the indexable right-angled shoulder milling tool is less than or equal to the planar arc radius of a socket of the sprocket to be machined, an indexable toroidal milling tool is used for finish machining, the radius of the indexable toroidal milling tool is less than or equal to the planar arc radius of the socket of the sprocket to be machined, the arc radius of the front end torus of the indexable toroidal milling tool is less than or equal to the bottom arc radius of the socket. The manufacturing method has the advantages that the requirement that tools different in diameters are required to machine different types and styles of sprocket sockets, repeated programming is not required, the arc radius of the planar tooth root of each sprocket socket can be smoothly continual with the arc radius of the tooth surface, the sprocket sockets are uniform in shape, and tooth form is even.
Description
?
Technical field
The invention belongs to metal working technical area, particularly relate to a kind of processing method of sprocket wheel.
Background technology
In today of mechanization, sprocket wheel is widely used in various industry, as aspects such as industry, agricultural, military affairs, health care, science and technology, very important effect is played in various field, in sweeping transmission process, sprocket wheel plays larger effect than gear, and sprocket wheel chain carrys out transmission, and gear is by intermeshing transmission.Compare with gear, sprocket wheel has single, double and many rows'.Under being applicable to low speed, heavy duty and hot conditions, the power of transmission and velocity interval are comparatively large, and compact conformation can realize larger gearratio, and efficiency is high, long service life, can be used in the occasion that diaxon center is far away.
Although the applicable situation of sprocket wheel is extensive, its cost of manufacturing compares gear ratio comparatively greatly, and it is higher to make requirement, and this just needs a rational technological process.
Summary of the invention
The invention provides a kind of processing method of mine flight conveyer sprocket wheel, realized by following technical proposals:
(1) adopt indexable right angle shoulder face milling cutters to carry out roughing, 1mm surplus is stayed in roughing, and milling cutter radius is less than or equal to sprocket wheel socket plane arc radius to be processed;
(2) adopt indexable round nose face milling cutters to carry out fine finishining, milling cutter radius is less than or equal to sprocket wheel socket plane arc radius to be processed, and cutter front end round nose arc radius is less than or equal to arc radius bottom chain nest.
The processing method of sprocket wheel of the present invention, solve well and use the tool sharpening variety classes of different-diameter, the requirement of different model sprocket wheel socket, without the need to overprogram, sprocket wheel socket plane fillet radius and the transition of tooth flank radius energy round and smooth, and chain nest shape is unified, profile of tooth is even.
Detailed description of the invention
Below by specific embodiment, the present invention is further illustrated.
Drag conveyor is one of colliery comprehensive mechanical coal mining equipment, and drag conveyor mainly drives round-link chain and scraper plate motion by sprocket wheel, thus drives material transportation.The quality of sprocket wheel quality directly affects the operating efficiency of drag conveyor.Sprocket wheel as main core component, the quality of the processing precision direct influence sprocket wheel of teeth portion chain nest and service life.
For improve sprocket wheel socket working (machining) efficiency, reduce costs, the processing method of sprocket wheel of the present invention, through considering correlative factor, adopt coated carbides indexable tool high-rate wireless LAN, roughing stays 1mm surplus to carry out fine finishining again.
By the center of sprocket wheel placing flat at rotary table, sprocket wheel socket plane circular arc is vertical with machine tool chief axis towards machine tool chief axis, arranges zero offset, workpiece is placed on the center of workbench and calibration of workpieces is fixed, adopt indexable right angle shoulder face milling cutters to carry out roughing, 1mm surplus is stayed in roughing.
Because fine finishining uses indexable round nose face milling cutters, cutter front end round nose arc radius should participate in sequential operation, and therefore, fine finishining programming route is different from roughing programming route.When using round nose face milling cutters fine finishining programming, profile of tooth arc radius should add stage property arc radius, and fillet radius should deduct knife tool arc radius, and tooth flank radius should deduct knife tool arc radius.
Use equipment is horizontal Machining centers.Programming coordinates system initial point is set in sprocket wheel socket bottom centre, by the normal equation of circle, finds out the relation between X value and Y value in cheating system; By program cycle computing, change straight-cut degree of depth Y value, service routine conditional circulation and the various functions such as unconditionally to turn to, utilize mathematical equation, calculate horizontal variable assignments X in every layer depth assignment.
Normal equation according to circle: (x-a)
2+ (y-b)
2=R
2
In formula, a, b are that the center of circle is horizontal, ordinate, and R is arc radius.Calculate that the center of circle in coordinate system is horizontal, the longitudinal coordinate value at ordinate value a, b and circular arc point of contact is crucial programming data.
Claims (1)
1. a processing method for sprocket wheel, is characterized in that comprising the following steps:
(1) adopt indexable right angle shoulder face milling cutters to carry out roughing, 1mm surplus is stayed in roughing, and milling cutter radius is less than or equal to sprocket wheel socket plane arc radius to be processed;
(2) adopt indexable round nose face milling cutters to carry out fine finishining, milling cutter radius is less than or equal to sprocket wheel socket plane arc radius to be processed, and cutter front end round nose arc radius is less than or equal to arc radius bottom chain nest.
