Abstract
A planar grinder with abrasive belt for grinding and polishing plane is based on existing one and features that it has additional units, including up-down moving mechanism with supporter, feeding mechanism under the grinding plate regulation mechanism, small turntable mechanisms on working platform of feeding mechanism, floating mechanism on each turntable mechanism, and electric control mechanism. Its advantages are high productivity, precision and quality, precise regulation of finish allowance, low impact, vibration and noise, low cost and long service life of abrasive belt.
Description
The present invention relates to flat surface grinding or polishing with equipment and control method.Belong to the grinding or the polishing on the made article of metal material and nonmetallic materials or metal material or nonmetallic materials plane.
Existing abrasive belt surface grinder comprises around the driving wheel of abrasive band driving mechanism, abrasive band on the regulating wheel of the driven pulley of abrasive band follower and abrasive band strainer, the abrasive band strainer is contained on the bearing support, abrasive band follower and abrasive band driving mechanism are contained in the bearing support and arranged on left and right sides respectively, and make its driving wheel, the distribution triangular in shape of driven pulley and regulating wheel, the pressure nog plate guiding mechanism that contacts with the abrasive band is housed in the lower end of bearing support, bearing support is by the cantilever support of column, and cooperate with the column cantilever is movable, column is fixed on the lathe bed.This grinding machine can only grinding or polish a workpiece after, send into a workpiece processing again, non-cutting time is long, bistrique can not the whole adjustment amount of feeding, working (machining) efficiency is low, the plane precision of workpiece to be machined is low, the abrasive band is shorter service life, the cost height.
The objective of the invention is to provides a kind of abrasive belt surface grinder and control method thereof at above-mentioned the deficiencies in the prior art, makes this grinding machine have high working (machining) efficiency and machining accuracy, abrasive band long service life.
In order to realize the foregoing invention purpose, technical scheme of the present invention is on existing abrasive belt surface grinder the abrasive band strainer that makes on the bearing support to be housed, the abrasive band driving mechanism, the abrasive band follower, the travel mechanism that presses nog plate guiding mechanism and abrasive band to move downward or upward with respect to workpiece to be machined simultaneously, on the lathe bed below the pressure nog plate guiding mechanism, feed mechanism is housed, little turntable mechanism with its motion is housed on the workbench of feed mechanism, and make each vertical center line of little turntable mechanism and press nog plate vertical, arbitrary little turntable mechanism on the workbench with feed mechanism move to press nog plate near right position, by actuating unit drive should be little turntable mechanism around its vertical center line rotation, be distributed with in each little turntable mechanism 3-15 all with the parallel relocation mechanism of the little vertical center line of turntable mechanism, the electrical control mechanism that this grinding machine has been installed.
The control method of abrasive belt surface grinder:
Autocontrol method circulates according to the following steps and carries out:
1. the connection power supply is opened source of the gas;
2. regulate bleed pressure P, and make its P 〉=5MPa;
3. have or not the abrasive band on the judgement grinding machine,, on grinding machine, adorn the abrasive band when on the grinding machine during no abrasive band; When on the grinding machine abrasive band being arranged, the tensioning abrasive band;
4. select the control mode of grinding machine, when being control automatically, start automatic selector switch; Simultaneously abrasive band and each self-operating of little turntable mechanism, but the two also low cruise, lubricated and dust collection mechanism can move;
5. the operation of big turntable mechanism;
6. when the workpiece no show Working position in the arbitrary little turntable mechanism in the big turntable mechanism, big turntable mechanism continues operation, and when it arrived Working position, big turntable mechanism was out of service;
7. bistrique moves down, and when the Working position of bistrique no show workpiece, bistrique continues to move down, and when bistrique arrived the Working position of workpiece, abrasive band and each self-operating of little turntable mechanism carried out; Also but high-speed cruising is processed;
When the process time of setting not then, continue processing, but also High-speed machining after arriving the process time of setting, is shut down process finishing; When not shutting down, move to spacing position on the bistrique, mechanism's operation is seen in abrasive band and little commentaries on classics meanwhile, but the two also high-speed cruising, setting process time is 5 seconds to 5 minutes;
9. after bistrique put in place, big turntable mechanism moved;
Hand operated control method:
1. the connection power supply is opened source of the gas;
2. regulate bleed pressure P, and make its P 〉=5MPa;
3. have or not the abrasive band on the judgement grinding machine,, on grinding machine, adorn the abrasive band when on the grinding machine during no abrasive band, when on the grinding machine abrasive band being arranged, the tensioning abrasive band;
4. when for manual operation, lubricate with dust collection mechanism and can move behind the startup manual selection switch;
5. abrasive band and each self-operating of little turntable mechanism; But also low cruise;
6. the operation of big turntable mechanism;
7. when the workpiece no show Working position in the arbitrary little turntable mechanism in the big turntable mechanism, big turntable mechanism continues operation, and when it arrived Working position, bistrique moved down;
8. when the Working position of bistrique no show workpiece, bistrique continues to move down, and when bistrique arrived the Working position of workpiece, abrasive band and each self-operating of little turntable mechanism, but also high-speed cruising were processed;
9. ought not finish and add man-hour, continue workpiece is processed, add man-hour when finishing, move on the bistrique, manual operation finishes.The present invention has following technique effect:
The working (machining) efficiency height, non-cutting time is few.Because a plurality of symmetries or asymmetric little turntable mechanism are housed on the workbench of feed mechanism, in each little turntable mechanism a plurality of relocation mechanisms have been installed, place workpiece to be machined on the relocation mechanism of each little rotation mechanism.When arbitrary little turntable mechanism and on relocation mechanism move to feed mechanism when pressing near the nog plate, driving mechanism drive this little turntable mechanism and on relocation mechanism rotate together, when the feed mechanism stop motion, the abrasive band that runs up processes workpiece, after the completion of processing, the feed mechanism motion, the abrasive band rotating speed reduces.Treat to process after workpiece is sent into grinding or polishing position.Can shorten the feeding time between workpiece to be machined and the workpiece to be machined so widely, thereby improve working (machining) efficiency widely.
The plane precision of workpiece to be machined, machining accuracy and crudy height can accurately be adjusted allowance.With the workpiece of this device processing, its 0＜flatness≤0.05mm, 0＜depth of parallelism≤0.03mm, the workpiece size precision is ± 0.05mm; Solved the problem of accurate adjustment allowance.This technique effect is mainly by the whole amount of feeding of adjusting of bistrique, presses the relocation mechanism in nog plate guiding mechanism and the little turntable mechanism to embody.
For impact, vibration, the noise of moment that reduces the abrasive band when contacting with workpiece to be machined, low-speed running when having taked the abrasive band contact workpiece and runs up after workpiece contacts, and has prolonged the service life in abrasive band.
Simple to operate, the reliable operation of the utility model, cost is low.
