Description
Cycloidal Wheel is the major part in the cycloidal pinwheel planetary gear speed reducer, and what the utility model was related is exactly the Cycloidal Wheel grinding machine of realizing this Cycloidal Wheel grinding task.
At present by the domestic Cycloidal Wheel grinding machine of producing without competition of Qin Chuan machine tool plant, for comparing stereotyped structure, its operation principle is to come tooth curve on the processing work by the cycloid generating by abrasive grinding wheel, and mainly vertically and laterally incision mechanism, workbench, working platform swing mechanism and dresser and operating mechanism thereof constitute by emery wheel, grinding wheel stand, grinding wheel stand for this grinding machine.Emery wheel is to contact by the point with the processing blank to grind workpiece, in grinding the blank process, emery wheel not only will have the horizontal amount of feeding that grinds, but also comprehensive longitudinally approach to be arranged, adopted a large amount of gear train transmission mechanisms in the therefore existing grinding machine, the entire equipment structure is very complicated, operating procedure is quite loaded down with trivial details, on this basis for guaranteeing the machining accuracy of institute's grinding work piece, needing diamond pen trimmer and operating mechanism thereof constantly repairs the shape of emery wheel, emery wheel and diamond all have bigger attrition, the equipment cost height.This existing grinding machine is because emery wheel and processed blank are the some grinding method, the workpiece revolution moves and can only grind a line week, in order to grind whole tooth surface, need operating mechanism to drive constantly feeding downwards of emery wheel, workpiece to be machined need change no several weeks just can be finished, every pair of workpiece of general grinding needs 2 hours time, and the production cycle is longer, and production efficiency is low; In addition, the Cycloidal Wheel that adopts this grinding method to process, its tooth-face roughness is difficult to improve, and is generally 0.8 μ m, and its surface smoothness and geometric accuracy are also lower.In sum, all drawbacks of existing Cycloidal Wheel grinding machine have shown that all it is very unscientific adopting the grinding method of emery wheel, demand urgently improving.
Goal of the invention of the present utility model is to provide a kind of novel Cycloidal Wheel grinding machine that can first mate's degree improves the Cycloidal Wheel working (machining) efficiency.
Another goal of the invention of the present utility model is to provide a kind of simple in structure, easy operating, Cycloidal Wheel grinding machine that automaticity is high.
Realize the Cycloidal Wheel grinding machine of foregoing invention purpose, its structure is formed and is comprised workbench, working platform swing mechanism and bistrique, it is characterized in that bistrique is for being wound on driving shaft and Xiao's axle, abrasive band bistrique by the abrasive band driven by motor, also include bistrique and laterally cut mechanism, this mechanism is by the slide carriage that the abrasive band bistrique is installed, the worm and gear micromotion mechanism of the small amount of feeding of control slide carriage, manually the clutch selection mechanism of tooth bar screw mechanism that adjusts and two mechanisms constitutes jointly, tooth bar one end of manual adjustment mechanism is as the worm-wheel shaft in the micromotion mechanism, the other end is equipped with manual handwheel, be provided with between tooth bar and the tooth cover and the clutch nuts of tooth bar engagement and with the movable rack sleeve that connects that embeds of clutch nuts one end, this sleeve other end place is provided with one and is connected with the tooth external threading, be installed with clutch on it and select the gland of handle, the fine motion handwheel of micromotion mechanism is installed on the worm screw, and slide carriage is fixedlyed connected with the tooth cover.
In technique scheme, for realizing the automation mechanized operation of the utility model Cycloidal Wheel grinding machine, also be provided with processing in this grinding machine and preset several automatic controls, it is dimerous by mechanical transducing part and circuit control, and be central control unit with the prset counter, circuit control section wherein is by presetting counter, the magnetic valve F2 of final value disjunction circuit relay contact control series connection with it in the counter, the contact of counting relay one by one of connecting with magnetic valve F1, being parallel to both ends of power jointly forms, magnetic valve F1 controls oil cylinder 1, promote the worm and gear micromotion mechanism through a ratchet mechanism, magnetic valve F2 control oil cylinder 2 drives slide carriage, realizes the slide carriage withdrawing; Its mechanical transducing part is to be installed in the counter revolution sensing head that eccentric wheel on the workbench main shaft and travel switch K1 thereof form, and provides processing capacity to prset counter.When processing capacity is all finished, prset counter opens solenoid valve F2 by oil cylinder 2 control slide carriage regression journeys, arrives when giving up the throne terminal point, by be installed on slide carriage move back journey retaining board terminal, be connected in the circuit for controlling motor major loop travel switch XK1 cut off circuit, grinding machine is quit work.
The improvement structure of working platform swing mechanism is in the above-mentioned technical scheme: directly drive worm gear by the workbench motor, the transmission lower table is made folk prescription to rotation, is revolved round the sun in the other direction with lower table by the moving change gear train of same worm screw drive, Bevel Gear Transmission pair, main shaft and adjustable eccentric drive upper table surface work simultaneously and forms.
The Cycloidal Wheel grinding machine that the utility model is designed, its main design concept is to replace the wheel grinding mode with the abrasive band, 1., the width in abrasive band is greater than the face width of tooth of work piece the advantage of sbrasive belt grinding mode is:, it contacts with workpiece alignment, is line processing and forming mode, and workpiece whenever circles, whole tooth surface all can obtain grinding, its production efficiency is higher than the some molding mode of emery wheel far away, and practice shows that shortened to 40 minute by original 2 hours the process time of every pair of workpiece; 2., owing to adopted the line contact grinding method in abrasive band, the comprehensive feeding mode of the needed length feed mode of original wheel grinding, horizontal cut-in manner and grinding wheel stand is simplified to single traverse feed cut-in manner greatly, also need not wheel dressing mechanism, it is greatly succinct that equipment is constituted, the complete machine cost drops to original 1/5th at least, operation sequence is simplified greatly, made things convenient for the operator, this all helps to improve product quality and production efficiency, and the simplification of device structure has also been created condition for further this grinding machine of realization automation control; 3., workpiece geometric accuracy and the surface smoothness that processes with the abrasive band improves greatly, its surface roughness only is 0.4 μ m, because the grinding in abrasive band is the elasticity grinding, and bigger area of dissipation arranged again, in process, can not make the workpiece to be machined distortion, burn or occur the crack performance of microcosmic, thereby the surface accuracy of workpiece and fineness are improved, improved the crudy of workpiece, also overcome simultaneously emery wheel and in the process of grinding, occurred the broken hidden danger that is caused suddenly, guaranteed production safety; 4., operation is very easy for the replacing in abrasive band, only needed to finish in 2-3 minute, saved the non-cutting time that existing Cycloidal Wheel grinding machine medium plain emery wheel is changed required levelling weighing apparatus and diamond pen finishing; 5., the use in abrasive band can make the processing cost of workpiece further reduce, though the quantity consumed in abrasive band is slightly larger than emery wheel,, be easy to again simultaneously change, so the economic benefit of grinding machine is still highly significant because of each abrasive band price only is 1/14 of an emery wheel price.In sum, the designed cycloid disc sharpener art of the utility model has production efficiency height, the processing work quality is good, simple in structure, easy to operate, automaticity is high characteristics.
