The specific embodiment
The course of work of camshaft numerical control sander bed of the present invention is as follows:
A kind of camshaft numerical control sander bed, comprise lathe bed 5, working plate 6, abrasive grinding wheel 7, headstock mechanism 1, bistrique assembly 3, tailstock system 14, rotate servomotor 8, vertically large slide unit 2, axial servomotor 9, compliant mechanism 4, feed servo motor 10, numerical control device 11, lathe bed 5 is provided with working plate 6, working plate 6 is provided with slide unit 18, working plate 6 is provided with T-shaped groove makes tailstock system 14 move axially along camshaft 16 directions, tailstock system 14 rear ends are provided with single-acting cylinder 15, use during camshaft 16 loading and unloading, working plate 6 rears are provided with vertically large slide unit 2, vertically large slide unit 2 is driven by axial servomotor 9 and does axially-movable, vertically large slide unit 2 is provided with compliant mechanism 4, headstock mechanism 1 is connected with and rotates servomotor 8, compliant mechanism 4 connects feed servo motor 10, compliant mechanism 4 is by feed servo motor-driven ball screw, abrasive grinding wheel 7 connects bistrique assembly 3, bistrique assembly 3 rotates abrasive grinding wheel 7, produce cutting force, numerical control device 11 is connected in lathe bed 5, connect by two extension springs 17 between vertically large slide unit 2 and the compliant mechanism 4, abrasive grinding wheel 7 contacts with camshaft 16, two springs 17 that are provided with by upper slide unit again produce flexible, assurance abrasive grinding wheel 7 organically combines with camshaft 16 and removes camshaft surface burr, lathe bed 5 belows are provided with floor push 13, thereby the intersection of working plate 6 and lathe bed 5 is provided with for digital control system 11 and starts instruction to start the starting switch 12 that whole lathe is finished the cyclic process process, add and be used for man-hour normal open and always stopping, abrasive grinding wheel 7 is located at the left side of compliant mechanism 4.In this practicality was new, abrasive grinding wheel 7 was skive.
Operation principle: a upper offset cam axle 16, after machining.Vertically large slide unit 2 is in the lathe farthest right position.Compliant mechanism 4 is in the lathe rearmost position, at this moment manually steps on floor push 13, and the camshaft 16 that processes is lifted down, and changes unprocessed another offset cam axle 16.Starting switch 12, after the startup:
The 1st step: abrasive grinding wheel 7 begins rotation under 3 effects of bistrique assembly, feed servo motor 10 drives compliant mechanism 4 and contacts camshaft 16 with abrasive grinding wheel 7, until receive the pressure appropriate signals.
The 2nd step: it is mobile from right to left that axially servomotor 9 drives vertical large slide unit 2 (together with compliant mechanism 4 and the abrasive grinding wheel 7 of top).This moment, abrasive grinding wheel 7 was finished first deburring process at camshaft 16.
The 3rd step: feed servo motor 10 drives whole compliant mechanism 4 and leaves camshaft 16, returns initial point.Rotation servomotor 8 drives the main shaft that is installed in the headstock mechanism 1 and rotates 180 °.Begin the processing of second batch of peak burr.
The 4th step: feed servo motor 10 drives whole compliant mechanism 4 contact camshafts 16, it is mobile from left to right that axially servomotor 9 drives vertical large slide unit 2 (together with compliant mechanism 4 and the abrasive grinding wheel 7 of top), and this moment, abrasive grinding wheel 7 was finished second batch of peak deburring process at camshaft 16.
The 5th step: after finishing second batch of peak deburring, vertically large slide unit 2 is parked in initial point (the right), and whole compliant mechanism 4 is return initial point (back) under feed servo motor 10 drives.Abrasive grinding wheel 7 stops operating under 3 effects of bistrique assembly, and the main shaft that rotates in the servomotor 8 drive headstock mechanisms 1 forwards 0 point (first surface) to.At this moment zero-bit is all got back to by system 11 on the numerical control device, waits for next loop start.
Manually the camshaft 16 that processes is taken off, load onto camshaft to be processed 16, repeat the 1-5 step.
In the 1st and the 4th step, can beat totally in order to guarantee on the camshaft batch peak burr, can prolong again grinding spindle and grinding wheel service life.
The technical scheme that the present invention proposes is: adopt flexible processing method, guarantee that camshaft can receive enough pressure.Reduce the rail friction resistance, stage clip elastic force is at any time with the kind capable of regulating.The control model of feed servo motor is set to the torque control model simultaneously, and a torque limit value Tt is set, and as actual torque Ta＜Tt, the motor forward is pressed forward, and when Ta＞Tt, the motor reversal pressure of drawing back is worked as Ta=Tt, motor stalling.Send simultaneously pressure and reach limited signal (being the pressure appropriate signals).Make vertically large slide unit left direction move, normal process is to headstock place, outside upper electrical control, mechanical aspects guarantees that by compliant mechanism pressure is relatively constant.By the cooperating of frame for movement and electrical control, solved the problem of inconsistency that exists in the manual processing like this.
Further need the problem of explanation to be, what need to keep is the pressure that is added on the camshaft, and the control of torque control mode is that motor has constant torque, and to be subject to grinding wheel pressure be dull corresponding relation for the torque of mandatory declaration feeding motor and camshaft for this reason.Because what grinding wheel and feeding motor adopted is the ball-screw syndeton, shown in Figure 3, comprise feed screw 19, ball nut 20, driving torque Tt21, axial compressive force Ea22, by related data [Wang Zhimin, Zhang Xizhong, Li Yong. ball-screw-transmission uses and development [J]. electromechanical engineering technology, 2004, (9)] pass of driving torque Te and axial compressive force Ea is among Fig. 3 as can be known:
In the formula: Ea---axial compressive force;
H---transmission efficiency, relevant with the screw mandrel nominal diameter with pitch;
Tt---motor-driven torque;
Ph---pitch (helical pitch)
This formula shows, in the situation that pitch and screw mandrel nominal diameter are determined, be proportional relation between driving torque Te and the axial compressive force Ea, dull correspondence, so the control of pressure just is converted into control to torque.
Camshaft numerical control sander bed of the present invention is controlled by digital control servo system, realized that multiple camshaft finishes the burr grinding on each blank surface, cam place continuously, automatically, especially a lot of peak burrs of criticizing are finished processing by the combination of flexible structure and digital control system in the upper/lower die adjacent side edge.Change the original manufacturing procedure of manually finishing that relies on fully, realized full-automatic, continuously processing, in process, kept the uniformity of technological parameter, guaranteed and improved crudy, greatly improved operating efficiency.
