Improved rotating workbench

Abstract

The invention provides an improved rotating workbench. The improved rotating workbench is simple in structure, can realize rotating, is high in running stationarity, great in stability and high in precision. The improved rotating workbench comprises a fixed disc and a movable disc, wherein the movable disc is movably connected with the fixed disc through a main shaft vertically arranged in the center of the fixed disc; a driving gear driven by a driving device is fixed on one side of the lower end of the fixed disc, a driven gear is correspondingly mounted at the lower end of the movable disc, and a guide wheel is arranged on the fixed disc; a toothed belt is arranged among the driving gear, the driven gear and the guide wheel; the front and rear two ends of the outer sides of the driving gear and the driven gear are separately provided with at least one guide wheel; toothed belt teeth are arranged on the outer side wall of the toothed belt; the bottom of a support column of one of the guide wheels is embedded in a groove hole in the fixed disc, so that the support column can slide along the groove hole; and the support column is fixedly connected with one end of a splint screw, and the other end of the splint screw penetrates through a fixed plate arranged on the fixed disc and is locked through a nut.

Description

technical field [0001] The invention relates to the technical field of workbenches, in particular to an improved rotary workbench. Background technique [0002] In terms of structural design, the existing mechanical worktable has a fixed connection structure between the tabletop and the stand. Its disadvantages are: when large workpieces are processed or handled on the worktable, the operator needs to move around because the tabletop cannot be rotated. It is very inconvenient to operate, and the mechanical workbench is very heavy. It is inconvenient to change the station through the movement of workers, and it is also inconvenient to carry heavy workpieces on the workbench.

[0002] In terms of structural design, the existing mechanical worktable has a fixed connection structure between the tabletop and the stand. Its disadvantages are: when large workpieces are processed or handled on the worktable, the operator needs to move around because the tabletop cannot be rotated. It is very inconvenient to operate, and the mechanical workbench is very heavy. It is inconvenient to change the station through the movement of workers, and it is also inconvenient to carry heavy workpieces on the workbench.

[0003] The existing rotary table is mostly driven by a worm and worm gear mechanism, but the cost of this structure is relatively high, and maintenance is relatively difficult. For occasions that do not require high precision, it is relatively wasteful.

There is also a relatively simplified structure, and there is also a structure that uses a belt drive. Since the tightness of the belt cannot be adjusted, there is a problem of belt drive slippage, resulting in low transmission accuracy.
