Description
技术领域technical field

Specifically, it involves the combination of servo motor, reducer, rack and pinion, and gap adjustment links, so that the rack and pinion that drives the sliding table can obtain a suitable transmission gap, so that this type of CNC machine tool has the positioning accuracy and repeatability that meet the requirements. positioning accuracy, and reduce the manufacturing cost of the machine tool.
背景技术Background technique
加工长轴类数控机床(通常滑台的移动距离大于6米)，其驱动滑台移动的结构不宜采用滚珠丝杠结构，比较多的是采用齿轮齿条结构，并且由双伺服电机驱动，便于控制齿轮齿条的传动间隙，但机床制造成本高。采用单伺服电机驱动齿轮齿条传动，并且与间隙调整机构加以组合，能够使齿轮齿条获得合适的传动间隙，即满足滑台定位精度和重复定位精度的要求，又降低了机床的制造成本。For processing long-axis CNC machine tools (usually the moving distance of the sliding table is greater than 6 meters), the structure for driving the sliding table to move should not adopt the ball screw structure, but more often use the rack and pinion structure, and are driven by double servo motors, which is convenient Control the transmission clearance of the rack and pinion, but the manufacturing cost of the machine tool is high. Using a single servo motor to drive the rack and pinion transmission, combined with the gap adjustment mechanism, can make the rack and pinion obtain a suitable transmission gap, which meets the requirements of positioning accuracy and repeat positioning accuracy of the slide table, and reduces the manufacturing cost of the machine tool.

工作原理：working principle:
将上述的部件一和部件二装配完成并且确认装配无误后，即可进入到传动间隙调整环节；当确认传动间隙大或小时，将锁紧螺母松开，用内六方扳手旋转调整螺杆和调整螺钉，使得减速机箱体绕着铰链轴旋转，即齿轮绕着铰链轴产生接近齿条或远离齿条的旋转运动；当确认传动间隙合适时，将锁紧螺母锁紧固定。在导轨上正反方向移动滑台，用激光干涉仪检测滑台移动的定位精度和重复定位精度；当定位精度和重复定位精度不符合要求时，重复上述调整过程，直至定位精度和重复定位精度符合要求为止。碟形弹簧用于平衡由于齿轮齿条加工精度误差所产生的间隙不均匀。After assembling the above-mentioned parts 1 and 2 and confirming that the assembly is correct, you can enter the transmission gap adjustment link; when it is confirmed that the transmission gap is large or small, loosen the lock nut, and use the hexagonal wrench to rotate the adjustment screw and the adjustment screw , so that the reducer box rotates around the hinge shaft, that is, the gear rotates around the hinge shaft to approach the rack or move away from the rack; when it is confirmed that the transmission gap is appropriate, lock and fix the lock nut. Move the sliding table in the positive and negative directions on the guide rail, and use the laser interferometer to detect the positioning accuracy and repeat positioning accuracy of the sliding table movement; when the positioning accuracy and repeat positioning accuracy do not meet the requirements, repeat the above adjustment process until the positioning accuracy and repeat positioning accuracy until the requirements are met. Disc springs are used to balance the uneven clearance caused by the machining accuracy error of the rack and pinion.
