Abstract
The utility model relates to modification on an existing gear miller. A workpiece on an operating table is driven to run by an operating motor. During gear cutting, a milling disc rotates to be in cutting motion and is driven to run by a disc motor on the operating table. A workpiece rotates to be subjected to tooth-dividing motion. A cradle is expanded relative to the workpiece and driven by a cradle motor, and the cradle rotates to lead a plane forming gear to additionally move along with rotational cutting motion of the milling disc, so that corresponding additional motion (differential motion) is formed on the basis of the original rotational tooth-dividing motion of the workpiece, and required tooth forms are formed by means of hobbing motion. During operation, an encoder is used for detection. Signals detected by the encoder are controlled by a numerical control system. The modified gear miller is wide in application range, vibration of the miller is low during operation, and roughness of tooth surfaces of gears is fine and precision and production rate are high.
Description
Technical field
The utility model relates to mill teeth machine field, specifically relates to a kind of improved numerical control gear milling machine.
Background technology
The utility model relates to mill teeth machine field.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: though this lathe can be processed the gear of maximum diameter of workpiece 110 mm, in fact when the diameter of work of processing near or reach 110 mm, machine vibration is very big, the gear teeth face roughness that processes is poor, working (machining) efficiency is low.When the gear number of teeth during, can not process less than 5 teeth; When the gear number of teeth during more than or equal to 5 teeth and near 5 teeth, because the inner a pair of worm couple rotating speed of lathe 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.Machine tool structure is complicated, and the transmission chain length is repaired and used duration, and the overhaul cost is high, and precision obviously descends after the overhaul.
Summary of the invention
In view of the defective that prior art exists, the utility model improves the HI-003 mill teeth machine of a precise decreasing, and the main wear phenomenon of former lathe is disappeared; Simplify the structure, strengthened rigidity, enlarged the range of work; Improved precision; Simple to operate, improved productivity ratio, reduced entreprise cost.
For realizing above-mentioned purpose, the technical solution that the utility model adopted is by work drive motor, workpiece, and facing cutter, cage chair, the cage chair motor, encoder, the cutterhead main frame, workbench is formed; Workpiece on workbench is turned round by the driving of work drive motor, and cutting adds man-hour, the motion of facing cutter rotary cutting, and facing cutter is turned round by the driving of the cutter motor on workbench; The rotation of workpiece divides the tooth motion; Cage chair is done generating motion with respect to workpiece; Cage chair receives the driving of cage chair motor; Because rotating, cage chair make plane-shaped gear production on the basis of facing cutter rotary cutting motion, produce additional movement; It is differential that the rotation of workpiece divides tooth motion corresponding additional movement of generation on the basis of original motion like this, forms needed profile of tooth through this rolling cut motion.In operation process, detect facing cutter rotary cutting motion in the tracking lathe through encoder, encoder is located at the homonymy of cutter motor, and the mill teeth machine adds in cutting and has 3 rotatablely moving continuously of being associated man-hour: i.e. facing cutter rotary cutting motion; The rotation of workpiece wheel blank divides the generating motion with respect to workpiece of tooth motion and lathe cage chair; 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.The signal that encoder detects is controlled by digital control system, and digital control system is the maincenter of Digit Control Machine Tool, and it accepts the pulse information that input unit is sent here; Compile, after computing and the logical process; Export various information and instruction, the various piece of control lathe, the orderly action of stipulating.
Improved mill teeth machine, machine vibration is little when the gear (even the processing diameter reaches the gear of 125mm) of processing diameter 110mm, and the gear teeth face roughness is good, precision is high, productivity ratio is high.
The beneficial effect that the utlity model has is that the main wear phenomenon of former lathe is disappeared, and simplifies the structure, and has strengthened rigidity; Enlarge the range of work, improved precision, simple to operate; Having improved productivity ratio, reduced entreprise cost, is a kind of new product with promotional value.
