Technical field
The present invention relates to a kind of numerically controlled cam shaft grinding machine trip-stop controlling organization, especially relate to the automatic trip stop controlling organization of a kind of Numerical Control Cam travelling wheelhead roll grinder.
Background technology
The numerically controlled cam shaft grinding machine trip-stop mechanism often driving-belt moving axis by wheel and rack (or tooth piece) rotates, thereby makes and move by the mill guide wheel, finishes in process leaning on the selection of grind away plate.The position by the mill guide wheel of existing trip-stop mechanism can not move back and forth arbitrarily, so trip stop speed is restricted, causes machine tooling efficient low; If also need change the workpiece kind, then need tooth bar (or tooth piece) is changed again or regulated, like this, tend to make that working (machining) efficiency reduces once more.And be difficult to realize continuous grinding processing when processing irregular workpiece.
The motion of Numerical Control Cam travelling wheelhead roll grinder comprises that high speed rotation, the feeding of emery wheel, the workbench of bistrique drive that coming and going of workpiece moved, the finishing of emery wheel and finishing feeding, by the trip stop of mill guide wheel etc., it selects six modes of controlling four-axle linked processing mostly for use.Wherein, bistrique rotation and crushing only need provide motion and halt instruction and get final product in process, need not participate in through transport control, and emery wheel feeding, workpiece are moved, the crushing feeding, by grinding action such as guide wheel trip stop, must be in grinding process by the programme-control processing that links.Therefore, the selection of Numerical Control Cam travelling wheelhead roll grinder logarithm control system is had relatively high expectations.At present, directly realize four-axle linked control mostly, like this, tend to improve the manufacturing cost of Numerical Control Cam travelling wheelhead roll grinder by digital control system with 4 linear axis controls.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the invention provides a kind of machine tooling efficient that helps improving, simple to operate, stable and reliable operation numerically controlled cam shaft grinding machine trip-stop controlling organization.
Technical scheme of the present invention is: it comprises servomotor and trip stop transmission device by the control of lathe master digital control system, the trip stop transmission device comprises gear shaft, pinion on the servo motor shaft and the gear wheel engagement of being located on the gear shaft, gear wheel and gear shaft fasten as one, gear shaft is located in the lathe housing, bearing is equipped with at the gear shaft two ends, gear shaft is meshed with the tooth bar power transmission shaft, bearing is fixed on can be in the lathe body shell reciprocating tooth bar power transmission shaft, shift fork one end is connected with bearing, the shift fork other end and contact by the mill guide wheel of can moving on guide wheel shaft contact by the grind away plate that leans on that grinds guide wheel and it is carried out profiling.
Described servomotor preferred Siemens 1FK7 synchronous servo motor.
During work, servomotor is by pinion and the through-drive of gear wheel driven gear, gear shaft drives the tooth bar power transmission shaft again and moves back and forth arbitrarily, on guide wheel shaft, move back and forth by the mill guide wheel through bearing and shift fork drive, thereby realize by the mill guide wheel in process to leaning on any location of grind away plate, when making on the grinding raised wheel shaft any one cam, can both programme by machine tool numerical control system control, make by the mill guide wheel with contact and carry out profiling by grind away plate corresponding site, realize that continuous grinding processes.
Use the present invention, can move back and forth arbitrarily according to actual conditions, can effectively improve machine tooling efficient by the position of grinding guide wheel.
The present invention is simple in structure, compact, and low cost of manufacture is easy to operate, and working stability is reliable, and high efficiency is applied widely.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is an A-A embodiment illustrated in fig. 1 place cross-sectional schematic.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises servomotor 10 and the trip stop transmission device by the control of lathe master digital control system, the trip stop transmission device comprises gear shaft 3, pinion 1 on 10 of the servomotors and gear wheel 2 engagements of being located on the gear shaft 3, gear wheel 2 fastens as one with gear shaft 3, gear shaft 3 is located in the lathe housing, bearing is equipped with at gear shaft 3 two ends, be beneficial to guarantee that gear shaft can rotate flexibly, gear shaft 3 is by servomotor 10 controls, realize any rotation of gear shaft 3, gear shaft 3 is meshed with tooth bar power transmission shaft 4, the rotation of gear shaft 3 can drive tooth bar power transmission shaft 4 and move back and forth arbitrarily, bearing 5 is fixed on can be in the lathe body shell reciprocating tooth bar power transmission shaft 4, shift fork 6 one ends are connected with bearing 5, and shift fork 6 other ends and contact by mill guide wheel 7 of can moving on guide wheel shaft 8 contact by the grind away plate 9 that leans on that grinds guide wheel 7 and it is carried out profiling.
During work, servomotor 10 is by pinion 1 and 3 transmissions of gear wheel 2 driven gear axles, gear shaft 3 drives tooth bar power transmission shaft 4 again and moves back and forth arbitrarily, on guide wheel shaft 8, move back and forth by mill guide wheel 7 through bearing 5 and shift fork 6 drives, thereby realize by mill guide wheel 7 in process to leaning on any location of grind away plate 9, when making on the grinding raised wheel shaft any one cam, can both programme by machine tool numerical control system control, make by the mill guide wheel with contact and carry out profiling by grind away plate corresponding site, realize that continuous grinding processes.
When using the present invention's numerically controlled cam shaft grinding machine trip-stop controlling organization, in order to reduce production costs, further increase work efficiency, the main digital control system of lathe can be selected Eco-power digital control system for use, three linear axis of preferred Siemens 802C(control, a rotating shaft), it is four-axle linked to substitute medium-sized digital control system realization, and the most frequently used medium-sized digital control system has 4 linear axis of Siemens 802D(control).
Siemens 802C digital control system can be controlled 4 axis servomotors as Eco-power digital control system, comprises three linear axis and a rotating shaft, is generally the rectilinear motion of three linear axis controls X, Y, three directions of Z, a rotating shaft control lathe spindle operation.
