Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.
As shown in Figures 1 and 2, a kind of pinion cutter gear grinding machines, comprise lathe bed 1, knife sharpener 2 with grinding tool, and knife sharpener 2 comprises emery wheel 21 and for driving the drive motors 22 of emery wheel 21, comprise control system, and lathe bed 1 is provided with slipway mechanism.Here, slipway mechanism comprises the smart two mountains type guide rail 31 and the first grating that form scraped of use, the first grating offers control system the first feedback signal, slipway mechanism and lathe bed 1 plane Cheng Du, and be fixed on (the present embodiment does not mark taper bolt) on lathe bed 1 by taper bolt, servomotor 4 drives slipway mechanism by screw mandrel 32, here, screw mandrel 32 is THK precision P0 level ball screw 32, this kind of screw mandrel 32 is a kind of efficient feed screws 32, its ball rolls between screw mandrel 32 axles and nut, compared with traditional sliding screw 32, the driving torque maximum of this screw mandrel 32 is only traditional 1/3rd, very be suitable for saving drive motors 22 power, in Fig. 1, the position of screw mandrel 32 is arranged on inside in fact, for convenient.Indexing part 5 is controlled by control system, and the indexing part 5 here comprises torque motor 51 and the second grating, and torque motor 51 is connected with control system, and the second grating offers control system the second feedback signal.
The operation principle of the present embodiment is: indexing part 5 is arranged on the guide rail 31 of slipway mechanism and can under the driving of servomotor 4, on guide rail 31, slidably reciprocates, in addition, torque motor 51 on indexing part 5 is also controlled by control system, and be provided with on the main shaft of torque motor 51, the workpiece assembling seat 6 of workpiece is installed, like this, workpiece is arranged on after workpiece assembling seat 6, control system is control moment motor 51 and servomotor 4 simultaneously, drive workpiece to rotate so that obtain torque motor 51, and servomotor 4 drives whole indexing part 5 to slidably reciprocate on slipway mechanism, after coordinating like this, just can realize the complete machining of workpiece.From the foregoing, this pinion cutter gear grinding machines have been cancelled traditional machine driving pattern, have reduced middle transmission mechanism, control the calibration of workpiece with control system, so, can control more accurately the calibration of workpiece, have improved the quality of product.In addition, control system can also, by controlling servomotor 4 and torque motor 51, realize the calibration of different size, has realized the workpiece of processing different size on same equipment.In addition, by screw 61(as shown in Figure 2) regulate the circular runout of workpiece assembling seat 6, thus radially maintaining in preset range and (be less than 0.002mm) with end face run-out of workpiece assembling seat 6 can be ensured.
In the present embodiment, grating is that Spain FAGOR linear grating is (due to too little and be hidden in indexing part 5 inside, the present embodiment does not mark), this grating can produce a feedback signal, and send control system to, control system just can be controlled respectively according to this feedback signal the action of servomotor 4 and torque motor 51 like this, here, this feedback signal comprises the displacement signal of the first grating generation and the angle signal that the second grating produces, specifically displacement signal has represented the displacement of indexing part, and angle signal has represented the rotational angle of torque motor.In addition, this linear grating has adopted newly designed mounting means, can reduce to greatest extent the trueness error producing due to variations in temperature.In addition, this pinion cutter gear grinding machines have been cancelled the required index plate of traditional pinion cutter gear grinding machines, involute cam, and the calibration of workpiece coordinates realization by torque motor 51 with the second grating, realize precision numerical control scale-division, the angle signal specifically producing by the second grating carrys out the rotation of control moment motor 51.This torque motor 51 is carried out closed-loop control by Spain FOGOR precision angular encoder, can realize any decile or decile not, and a point number of teeth is not limit, and resolution ratio is the function of (0.001 spends) accurately; Slipway mechanism, for realizing and the Involute interpolation of dividing spindle, has been realized the accurate formation of involute.Wherein, indexing part 5 has been cancelled the turbine and worm transmission mode of traditional dividing head, the torque fluctuations having produced because of gear transmission while having eliminated grinding completely, backlass and speed restriction; Because the rotor of torque motor 51 own does not directly contact with stator, so there is not mechanical wear, realize the object that precise decreasing does not appear in dividing spindle for a long time.In addition, this precision main shaft has used the grease lubrication of import, does not non-maintainingly melt, without other oiling.In addition, in the present embodiment, indexing part 5 is arranged on slipway mechanism by a base, and base can slidably reciprocate under the drive of screw mandrel 32 on slide rail simultaneously.
In the present embodiment, control system comprises Trio motion controller and a liquid crystal touch screen, and special roll flute software is installed in motion controller, inputs the parameter of serrated knife by touch-screen, controls reset and the start and stop of this pinion cutter gear grinding machines.So, this pinion cutter gear grinding machines are realized easy and simple to handle, without numerical control operating experience, have abandoned traditional C NC system and undertaken being transmitted to after macroprogramming by computer again the troublesome operation of system, directly carry out parameter and control lathe by liquid crystal touch screen.
Further, knife sharpener 2 is provided with protective cover 211, and protective cover 211 is circular; and be provided with a semicircular opening, and protective cover 211 is provided with dust exhaust apparatus, and dust exhaust apparatus comprises sweep-up pipe 212; sweep-up pipe 212 is fixed on protective cover 211, and the mouth of pipe of sweep-up pipe 212 is arranged on the below of emery wheel 21.
By adopting technique scheme, the protective cover 211 arranging on knife sharpener 2, can shield, and when sharpening emery wheel 21 is because of unexpected cracked, can prevent that fragment from flashing.Emery wheel 21 ashes that the dust exhaust apparatus arranging on protective cover 211 can be processed sharpening emery wheel 21 generation siphon away, and improve working environment, thereby ensure workman's health, and the mouth of pipe of sweep-up pipe 212 is arranged on emery wheel 21 belows, can increase the effect of dust suction.
Further, as shown in Figure 3, slide unit parts 3 are provided with bellows 33, and bellows 33 one end are connected with indexing part 5, and the other end is connected with servomotor 4.So,, in bellows 33 is wrapped in guide rail 31 and screw mandrel 32, when indexing part 5 slides, bellows 33 equally also can stretch, and can not have influence on the normal slip of indexing part 5.
By adopting technique scheme, just can effectively prevent that foreign material from falling on slide rail and screw mandrel 32, thereby ensure the normal slip of indexing part 5.
