Sliding table based on worm gear row

Abstract

The invention discloses a sliding table based on a worm gear row. The sliding table is characterized by comprising a linear rail fixing seat, linear rails and the gear row are arranged on the linear rail fixing seat, a plurality of uniformly-distributed gears are arranged on the gear row, the sliding table further comprises a sliding block fixing seat, a worm fixing seat is fixedly connected to the sliding block fixing seat, a worm is rotationally supported on the worm fixing seat, the worm is matched with the gear row, a servo motor is further arranged on the worm fixing seat, the servo motoris connected with the end of the worm through a belt pulley transmission pair, at least two supporting parts are arranged on the worm fixing seat, a movable working platform is jointly supported at the top ends of all the supporting parts, sliding blocks are arranged at the bottom end of the worm fixing base, and the sliding blocks are slidably connected to the linear rails.

Description

technical field [0001] The invention relates to a slide table, in particular to a slide table based on a worm gear row. Background technique [0002] The linear slide table is a mechanical structure that can provide linear motion. It can be used horizontally or vertically, and can also be combined into a specific motion mechanism-that is, multi-axis motion such as XY axis, XYZ axis, etc. in the automation industry. mechanism. Generally speaking, a linear slide table will have a driving part and a sliding part. The driving parts of the traditional linear slide table are various, but these driving parts (transmission pairs) have exposed different problems during use: [0003] 1. Hydraulic lifting structure. The piston of the oil cylinder will wear the oil seal after long-term use, resulting in oil leakage in the oil cylinder, and the problem of falling is prone to occur during vertical lifting movement, posing a safety hazard. [0004] 2. Screw nut structure. The screw and...

Problems solved by technology

During the working process of the gear-tooth row transmission pair, only three tooth surfaces on the gear are always in contact with the teeth on the gear row. At the moment of starting or stopping, the transmission sound is loud and generates noise; and the gap between the gear and the gear row The contact surface is extremely small (in fact, there is only a line contact between the two), on the one hand, it will cause stress concentration, resulting in a serious limitation of the overall load of the slide table, and on the other hand, it will also affect the overall service life of the slide table
