A bolt tightening device

Abstract

The invention discloses a bolt screwing-down device which comprises a support. The support is provided with a horizontal linear sliding mechanism which is provided with a lifting mechanism. The lifting mechanism is connected to the horizontal linear sliding mechanism through a universal joint. An automatic wrench is arranged on the lifting mechanism. By the adoption of the bolt screwing-down device, an installing system formed by the support, the horizontal linear sliding mechanism and the lifting mechanism is used for installing the automatic wrench, the handheld weight of workers is reduced, physical power is saved, and safety accidents are avoided. The automatic wrench can adjust the horizontal position and height through the horizontal linear sliding mechanism and the lifting mechanism, the sliding block origin locating device can carry out adjustment according to different products, application is more flexible, and the use range is wider.

Description

technical field [0001] The invention relates to the field of auto parts assembly, in particular to a bolt tightening device. Background technique [0002] Since the assembly factory of car seats is a labor-intensive area, the traditional assembly of various accessories such as seat frames and seat basins is done manually. Workers hold automatic wrenches to tighten each bolt, which will cost a long time. Workers have a lot of physical strength, and it is easy to cause safety accidents; in addition, the use of manual work is not as good as automated equipment in terms of labor cost, process, quality, efficiency, working hours, etc.; therefore, an automatic wire feeding and tightening system has emerged for the seat of the seat. The assembly of the frame and the seat basin, in this system, the worker pre-installs the workpiece on the line, and then flows to the assembly station after confirmation, and performs mechanized assembly after positioning. The connecting screws with t...

[0002] As the assembly plant of car seats is a labor-intensive area, the assembly of various accessories such as traditional seat frames and seat pans is done manually. Workers hold automatic wrenches to tighten each bolt, and long-term operation will consume Workers have a lot of physical strength, and it is easy to cause safety accidents; in addition, the performance of manual operations is not as good as that of automated equipment in terms of labor costs, processes, quality, efficacy, and working hours; therefore, an automatic wire feeding and tightening system has appeared for seat The assembly of the frame and the seat basin. In this system, the workers pre-assemble the workpiece on the line. After the confirmation is completed, it flows to the assembly station. After positioning, the mechanized assembly is carried out. The connecting screws with the seat frame are either vertical or oblique. This assembly process requires a positioning mechanism and a wire feeding and tightening mechanism to complete; but there is still a big gap between automation equipment and manual labor in terms of flexibility.
