Definitions

  • the invention relates to a horizontal honing machine for working up cilin- drical bores, for which a very good quality of the worked surface and a high accuracy of measure are required, such as for example are required for cilinder walls of hydraulic and pneumatic installations.
  • the honing activity is effected by means of strips of grinding material, placed upon the circumference of a dilatatable bearer (honing head), which is moved simultaneously axially and rotationally by a sled in the bore whereby a spiral grinding process in both directions to and fro is taking place.
  • polishing grooves are formed in a crosswise manner.
  • the reversal motion of the axial drive is most critical. Any slackening of speed or stagnation of the axial motion with regard to the continuously rotating motion will cause a local increase of grinding off more material, such that the bore will become locally wider.
  • Horizontal honing machines with a sled for large stroke lengths (of 1000 mm up to 10.000 mm) are known, wherein the axial drive of the sled is carried out either hydraulically or electromechanically.
  • the disadvantage of a hydraulic drive of the sled is the fact that this requires an excess of installed power, in order to be enabled to deliver the power peak for fast reversal.
  • the horizontal honing machine with driven sled for large and small stroke lengths comprising a frame with a guiding bar and with a linearly driven sled with a motor for the rotatory motion of the honing head is characterized according to the subject invention, in that the drive of said sled is moved by a direct current motor with servo control and solidstate transistor adjustment, whereby the speed and the reversal point of the motion of the sled in the stroke are almost independant from the load and are accurately repeating. For said controlling three systems are appropriate.
  • the controlling can be effected by means of a threephase thyristor convertor.
  • the controlling can also be effected by a direct current transistor regulator in combination with a brushless synchrone motor having permanent magnets at the rotor and coils at the stator.
  • the current fed to the coils is electronically commuted.
  • the preferred embodiment is a transistor with pulse width modulation. With this device the alternating tension is first rectified and subsequently equably chopped.
  • the tension at the rotor collector connections is influenced by varying the width of the pulses.
  • the frequency of the pulses ranges from about 1000 to 10.000 Hz.
  • the driving power is provided by a closed circuit for speed regulation having short reaction periods.
  • the switching over of the servo control can be effected by a sequence of signals which are introduced according to a preset programme for continuous production tasks.
  • the axial speed during the honing process ranges between about 10 and 40 m/min.
  • the power drive used in accordance with the invention renders the possibility to retard the sled with the honing head at an axial speed of 30 m/min, to effect the reversal without perceptible standstill and to bring it to the set speed in the reverse direction again within 1/3 second.
  • a second advantage of the drive according to the invention is the feature that with an equally remaining adjustment of the speed of the axial motion a very accurately set point of reversal of the sled is obtained, which
  • the power installed for the drive is 15 kW at the utmost.
  • the drive is delivering only the power which is to be used at any moment. During the reversal the peak charge to drag and to start running up
  • the drive with control according to the invention enables to make the reversal of the sled accurately also in case of high axial speed (40m/min), so that during the honing of blind bores the optimal speed can be applied.
  • the servomotor has a low inertia momentum and it can endure the high strengths of current during short periods which are necessary for the start of running up and for the dragging operations.
  • Figure 1 shows in part a schematic crosspection of the installation according to the invention.
  • (1) is the servomotor, (2) a tachogenerator, (3) a reductor, (4) the sled, (5) the motor for the rotatory drive, (6) the honing head with the honing stone (7) in the piece of work (8).
  • Figure 2 shows schematically the electrical control circuit of the installation.
  • (1) is the servomotor, (2) the tachogenerator, (9) a potentiometer, (10) a Reed-relay, (11) a gradient generator, (12) a servo amplifier, (13) an internaLcurrent circuit.
  • the servomotor (1) has low inertia momentum and it can endure high currents during short periods, which are necessary for start and dragging.
  • the tachogenerator (2) is mounted upon the shaft of the servomotor (1).
  • the reductor (3) has a low inertia momentum too and its construction is with inconsiderable play.
  • a potentiometer (9) is mounted, which delivers a tension linearly proportional with the angle of adjustment.
  • This adjusted value is switched over to the servo amplifier (12) by means of the Reed-relay (10) with mercury contacts, which have a switching delay of about 2 milliseconds.
  • the signal of the adjusted value is fed into the gradient generator (11), which transforms a non-linear signal into a value of tension including or declining linearly with time, and thus provides for uniformly accelerating start and uniformly retarded dragging respectively of the motor (1).
  • the tachogenerator (2) at the shaft of the motor (1) delivers a tension increasing linearly with speed of rotation and the polarity of which depends from the direction of rotation.
  • This signal of the tachogenerator pursuant to the gradient generator(11) is compared with the adjusted value.
  • the servoamplifier (12) controls the current and the tension for the motor (1) in such a manner, that the measured signal of the tachogenerator
  • An internal current circuit (13) is added to provide for a feed-back signal in order to obtain a precise adjustment of the rotatory moment.
  • the drive renders the possibility to enable the sled and all the accessories connected with it as well as the honing equipment to move to and fro, with a speed of 40 m/min.
  • the sled shall stop in it at the end of the stroke flexibly and accurately reaccelerate without noticeable standstill.
  • the stroke depth is about 10.000 mm.
  • the displacement length is about 13.000 mm.
  • the running up and dragging respectively of the sled is uniformly accelerated and uniformly retarded respectively.
  • the maximum torque is hardly higher than the continuously admissible torque of 30 Nm.
  • the maximum motor current is considerably lower than the admissible peak of 140 Amp.
  • the servo motor has sufficient reserve strength.
  • the gauge For the augmentation of the speed in the stroke from 30 to 40 m/min the gauge has been displaced because then the running out distance of the sled was longer.
  • the augmentation of the rotational load is resulting from the increase of the speed in the stroke.
