Abstract
The utility model relates to a CNC gear grinding machine for metallurgical saw blades. The gear grinding machine mainly comprises a power device, a driving device, a wheel grinding device, a dividing device and a saw blade sending device. The gear grinding machine is characterized in that the machine further comprises an automatic control device of a CNC numerical control system; and the device can accurately control the working modes and the working time of a main motor, a gear servomotor and a turning servomotor through processing input data and feedback information, so as to accurately control the rectilinear motion, the precessional motion and the motion distance of the mechanical parts of a grinder. Particularly, the rotation angle of a rotary table of the divided worm wheel can be accurately controlled, and the theoretical value of the control accuracy of the system can reach 0.01mm, so that the gear grinding machine has infinite dividing function. Therefore, the gear grinding machine can not be restricted by the number of teeth of the saw blade during saw blade repair, and has high adaptability to the damaged condition of the saw blades; and the repair accuracy is higher than industry standard at present. The mechanical structure of the machine tool is simple, and the operation is convenient.
Description
Technical field
The utility model belongs to saw blade roll flute processing equipment, is specifically related to a kind of CNC numerical control metallurgical saw gear grinding machines.
Background technology
Metallurgical saw is very big at current metallurgy industry consumption, main cause is the current not unlimited tooth function of dividing of saw blade gear grinding machine, the scope that saw blade is repaired in processing is subjected to certain restriction, and the saw blade that makes a lot of repairing and reusings again has to scrap, and causes the waste of resource and the increase of production cost.
At present, gear grinding machines both domestic and external generally adopt the vertical design that machinery control divides tooth.Machinery control divides tooth generally to have shift fork to push away saw and divides that tooth, fluted disc pull out tooth, the gear-box speed change is divided three types in tooth.This several minutes not unlimited tooth functions of dividing of tooth mode to damaging the bad adaptability of saw blade, all have certain requirement to profile of tooth, the number of teeth of damaging saw blade.For example: shift fork pushes away saw and divides tooth big to the error of jagged, as to stick with paste tooth saw blade reparation tooth pitch, and fluted disc pulls out tooth, the gear-box speed change divides tooth then the number of teeth to be had requirement, can only repair the saw blade of several specification numbers of teeth.The vertical design of gear grinding machines causes having tunnel vision of working position, is unfavorable for the monitoring of operating personnel to the course of work.
The utility model content
Provide a kind of CNC numerical control metallurgical saw gear grinding machines for solving the problems of the technologies described above the utility model, this machine automaticity height has unlimited minute tooth function, and is simple to operation.
The utility model mainly comprises power set, transmission device, the wheel grinding device, divide tooth device and saw blade feed apparatus, it is characterized in that: the utility model also comprises the automaton of a CNC digital control system, this device is by special-purpose computer, respectively with main motor, gear servomotor and rotary servovalve motor connect, accurately control main motor by processing to input data and feedback information, the working method of gear servomotor and rotary servovalve motor and working time, thereby accurately control the rectilinear motion of grinding machine mechanical part, revolve motion and move distance, to reach the purpose of the impaired saw blade of accurate reparation.Owing to introduce the automaton of CNC digital control system, just can control accurately minute angle of tooth worm gear rotary table rotation, the control accuracy calculated value of this system can reach 0.01MM, makes to the utlity model has unlimited minute tooth function.
As another technical scheme of the present utility model be: the horizontal setting that wheel grinding device of the present utility model and the mode of dividing the tooth device to install adopt transverse horizontal to distribute.Can make the visual field of saw blade working position openr, be convenient to the monitoring of operating personnel process.
The utility model has the following advantages with respect to prior art:
The utlity model has unlimited minute tooth function, be not subjected to the restriction of the saw blade number of teeth; To the adaptability height of saw blade damaged condition, comprise burr, stick with paste tooth and light base saw blade all can be repaired, the accuracy of reparation is higher than present industry standard.The frame for movement of lathe is simple, handled easily.
Description of drawings
Below in conjunction with the drawings and the specific embodiments utility model is described in further detail,
Fig. 1 is a structural representation of the present utility model
The specific embodiment
As shown in Figure 1, the utility model mainly comprises power set, transmission device, wheel grinding device, divides tooth device, saw blade feed apparatus and CNC numerical-control automatic control device.Mainly comprise particularly with regard to present embodiment: main motor 1, belt 3, emery wheel 4, divide tooth worm gear rotary table 8, advance screw mandrel 9, feed nut 10, rotary servovalve motor 13, rotary reducer 12, gear 14, gear reduction unit 15, gear servomotor 16, screw mandrel 17, tooth bar 18, gear 20, bistrique seat 21, lathe bed 22, feeding handwheel 23; Wherein main motor 1 and emery wheel 4 are fixedly mounted on the T type bistrique seat 21, gear 20 is installed in the bottom of T type bistrique seat 21, gear 20 cooperates with the horizontally disposed tooth bar 18 of making the feed nut type, is connected with gear servomotor 16 by screw mandrel 17, gear 14, gear reduction unit 15 again.Main motor 1 drives emery wheel 4 by belt 3 and rotates the feeding of 16 control emery wheels 4 of gear servomotor and the distance of feeding.Divide tooth worm gear rotary table 8 activity levels to be installed on the lathe 22, with the correspondence position of emery wheel 4 maintenance horizontal cross, the bottom is provided with feed screw mandrel 9 and is connected with feed nut 10 and with feeding handwheel 23, the feeding and the feeding distance of control saw blade.Divide tooth worm gear rotary table 8 to be provided with rotary servovalve motor 13 and rotary reducer 12, rotary servovalve motor 13 drives by rotary reducer 12 and divides tooth worm gear rotary table 8 revolution work, and saw blade is carried out the branch tooth.The CNC digital control system then is connected with main motor 1, gear servomotor 16 and rotary servovalve motor 13 respectively by electric wire.The CNC digital control system is by accurately controlling the working method and the working time of main motor 1, gear servomotor 16 and rotary servovalve motor 13 to the processing of input data and feedback information, thereby the rectilinear motion of control grinding machine mechanical part, revolve motion and move distance, to reach the purpose of the impaired saw blade of accurate reparation.Wherein, the unlimited minute tooth function of this machine finished in the following manner: at first calculate the angle of branch tooth worm gear rotary table 8 rotations according to 13 1 step angles of rotary servovalve motor by twice decelerometer, a step angle is exactly a pulse of sending to rotary servovalve motor 13, draws branch tooth rotary table as calculated and revolves three-sixth turn and need how many pulses.Calculate according to the requirement of the saw blade number of teeth man-hour adding, calculate and programme after good, input CNC digital control system, system carries out information processing and sends instruction, device power-up work.The control accuracy calculated value of this system is 0.01MM, is higher than present industry standard.
