Abstract

The present invention relates to a drive mechanism of twin-worm wheel applied in machine tool, comprising a secondary worm wheel reducer which can be slightly regulated and is arranged on a guide screw; the reducer includes a worm shaft, a worn wheel case, a worm wheel which is arranged in the worm wheel case and has inner screw thread; the inner screw thread engages with the guide screw, the worm shaft is vertical with the guide screw and the worm wheel case is fixedly connected with a sliding element which can be driven to slide along the vertical pole or the dragging board by the worm wheel case. The manual adjustment of the worm shaft on the secondary worm wheel reducer can drive the worm wheel on the secondary worm wheel reducer to move slowly along the guide screw, and the worn wheel case can impel the sliding element to slide along the vertical pole or the dragging board; thus, the position of the sliding element is slightly adjusted, thereby realizing the precise position effect.

Description

technical field [0001] The invention relates to a double worm and worm gear transmission mechanism, in particular to a double worm and worm gear transmission mechanism for machine tools. Background technique [0002] Generally, when the machine tool adjusts the cutting or cutting height or width, it is realized by turning the motor or driving the handwheel. In the actual operation process, on the one hand, it is quite inconvenient to use the hand wheel; on the other hand, if the motor is used to drive, the power is usually large, and the sliding part (usually the tool holder seat for installing the tool) moves quickly and is difficult to control. [0003] In the utility model CN2675316Y (authorized announcement date is February 2, 2005), a worm and worm gear transmission lifting mechanism for wire cutting machine tools was described, which applied the worm and worm gear reducer with large transmission ratio, stable operation and compact structure to the wire cutting machine ...
