Differential servo driven swinging/moving workbench device

Abstract

The invention discloses a differential servo driven swinging / moving workbench device. The device comprises first and second mechanisms which have the same structure and are arranged in parallel with each other, and an upper workbench which is vertically positioned above the first mechanism and the second mechanism, wherein the first mechanism and the second working mechanism at least comprise bases, motors fixed at end parts of the bases, ball screw pairs accommodated in the bases, and leading screw nut support sliding blocks fixedly connected with the ball screw pairs. Thus, the ball screw pairs are moved under the drive of each motor respectively, and the upper workbench is driven by the leading screw nut support sliding blocks to move; when the motor speeds and the rotation directions of the first mechanism and the second mechanism are the same, the upper workbench is moved horizontally; and when the rotating speeds and the rotation directions of the first mechanism and the second mechanism are different, the upper workbench performs small-angle swinging. Thus, the workbench device not only can be moved horizontally but also can perform the small-angle swinging.

Description

【Technical field】 [0001] The invention relates to a rotary worktable device, in particular to a swing / movable worktable device driven by a motor. 【Background technique】 [0002] Chinese invention patent No. 200810107995.6 discloses a rotary table device, including a base 9, a frequency conversion motor 3, a transverse axis 6, a vertical axis 27, a rotary table 29, a rotary table 1, and a small bevel gear 11 and a large bevel gear 19. Wherein, the turntable 1 is slidingly connected with the base 9 through the linear guide pair 7, and the turntable 1 is provided with a seat cavity 15 for accommodating the transverse shaft 6, the vertical shaft 27, the small bevel gear 11 and the large bevel gear 19; One end of the shaft 27 is fixedly connected with the rotary table 29 by screws, and the other end extends into the above-mentioned seat cavity 15; a large bevel gear 19 is installed on the above-mentioned vertical shaft 27, and the shaft of the large bevel gear 19 and the vertica...

AI Technical Summary

Problems solved by technology

[0003] However, in some cases, the workbench needs to swing at a small angle within a certain range, such as the processing of propeller blades or the processing of space-complex cams. At this time, the technical solutions described in the above patents cannot meet this demand. At the same time, in the above-mentioned device, since the transmission requires two pairs of gears, one large and one small, the cost is relatively high.
