Abstract
The invention provides an improved transmission system of a gear milling machine based on a numerical control (NC) technology. The improved transmission system is characterized by comprising a milling cutter disk, a wheel blank, a differential, a clutch, a cradle, a feed motor, a main machine, a differential change gear and an index change gear. The equipment adopted in the NC technology comprises an NC system, a feed servo system, a detection element, a mechanical transmission component and a linear rolling guide rail pair. In the invention, three types of associated continuous rotation movement exist during the gear cutting process of a gear milling machine: (1) rotary cutting motion of the milling cutter disk; (2) rotary gear dividing motion of a workpiece (the wheel blank); and (3) generating motion of the cradle of a machine tool relative to the workpiece. The improved transmission system has the beneficial effects of avoiding the main wear phenomenon of the original machine tool, simplifying an internal structure, shortening a transmission chain, strengthening rigidity, expanding machining range, improving precision, ensuring simple operation process, improving production efficiency and lowering cost.
Description
Technical field
The present invention relates to a kind of mill teeth machine transmission system, in particular, relate to a kind of modified mill teeth machine transmission system based on Numeric Control Technology.。
Background technology
The present invention relates to a kind of mill teeth machine transmission system.When H1-003 extension epicycloid bevel gear mill teeth the machine that existing machine tool plant produces can be processed maximum diameter of workpiece 110 mm, the number of teeth 5～80, the Equal-Height Spiral Bevel Gear of modulus 0.3-1.5 mm (extending the epicycloid bevel gear).This lathe exists significantly not enough: poor rigidity, though this lathe can be processed the gear of maximum diameter of workpiece 110 mm, in fact when processing diameter of work near or reach 110 mm, machine vibration is very big, the gear teeth face roughness that processes is poor, and working (machining) efficiency is low.The range of work is narrow, when the gear number of teeth during less than 5 teeth, can not process; When the gear number of teeth during more than or equal to 5 teeth and near 5 teeth, because a pair of worm couple rotating speed of lathe inside is very high, near the highest warning rotating speed of Machine Tool design, the lathe wearing and tearing are very serious.Continuous this gear of processing, less than half a year lathe just need overhaul even scrap.It is difficult to repair, the machine tool structure complexity, and the transmission chain length is repaired and is used duration, and overhaul cost height, and precision obviously descends after the overhaul.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the invention provides a kind of modified mill teeth machine transmission system based on Numeric Control Technology.
The present invention is the existing technical scheme that technical problem adopted of solution: modified mill teeth machine transmission system is by facing cutter, wheel blank, and differential mechanism, clutch, cage chair, feed motor, main frame, the differential change gear, index change gear is formed; Main frame links to each other with differential mechanism, cage chair, and differential mechanism links to each other with index change gear, and cage chair links to each other with facing cutter, and facing cutter links to each other with wheel blank, and cutting adds man-hour, the motion of facing cutter rotary cutting; The rotation of wheel blank divides the tooth motion; Cage chair is done generating motion with respect to wheel blank; Cage chair rotates the driving that is subjected to feed motor, under the control of clutch, the running of control differential change gear, index change gear links to each other with differential mechanism respectively with the differential change gear, the velocity of rotation of control gear, make plane-shaped gear production produce additional movement on the basis of facing cutter rotary cutting motion, the rotation of wheel blank divides the tooth motion to produce corresponding additional movement (differential) on the basis of original motion like this, forms needed profile of tooth by this rolling cut motion.
Numeric Control Technology in the mill teeth machine transmission system comprises digital control system, the feed servo system, and detecting element, mechanical transmission component and straight-line rolling are led and are held pair.
⑴ digital control system is the maincenter of Digit Control Machine Tool, and it accepts the pulse information that input unit is sent here, compiles, after computing and the logical process, exports various information and instruction, the various piece of control lathe, the orderly action of stipulating;
⑵ feed servo system selects variable reluctance stepping motor, hybrid type stepping motor, DC servo-motor or AC servomotor for use by different requirements usually on Digit Control Machine Tool;
⑶ the effect of detecting element is the actual value that detects displacement and speed, and sends feedback signal to numerical control device or servomechanism installation, thereby constitutes closed-loop control;
⑷ mechanical transmission component relies on mechanical part to carry out transmission and transmits;
⑸ straight-line rolling is led the parts (as saddle) of holding pair and can making lathe and is carried out linear reciprocating motion;
The cutting of mill teeth machine adds and has 3 rotatablely moving continuously of being associated man-hour: 1. facing cutter rotary cutting motion; 2. the rotation of workpiece (wheel blank) divides the tooth motion; 3. the lathe cage chair is with respect to the generating motion of workpiece.
Because rotating (being feed motion), cage chair make plane-shaped gear production on the basis of facing cutter rotary cutting motion, produce additional movement, the rotation of workpiece divides the tooth motion to produce corresponding additional movement (differential) on the basis of original motion like this, forms needed profile of tooth by this rolling cut motion.
The remarkable beneficial effect that the present invention has is: the main wear phenomenon of former lathe is disappeared, and mill teeth machine internal structure is simplified greatly, and driving-chain shortens greatly, has strengthened rigidity, enlarged the range of work, improved precision, the accent machine is convenient, simple to operate, improved productivity ratio, reduced improvement cost.
