A kind of multifunctional screw locking device for car seat

Abstract

The invention relates to a multifunctional screw locking device for an automobile seat, and belongs to the technical field of automobile assembly tools. The multifunctional screw locking device comprises a screw gun body, an end cover, a gun handle, a connection barrel, a connection ring, a bearing sleeve, an end sleeve, a rotating shaft, a motor, a speed reducer, a switch, a multifunctional gun head, a connecting piece, a carbon arm and a spherical universal joint. Two types of gun heads are integrated together, the automobile type is manually recognized, switching between a hexagonal screw sleeve head and a wedge rod can be achieved through the effect of a spring, and tightening of different screws is achieved. Tightening of different screws can be achieved only by arranging one gun for each station, the cost is saved, and the problem that operators replace screw guns without stop is avoided. Meanwhile, the lower end of the carbon arm is rotationally connected with the connecting piece through a pin shaft, the screw locking device can only move in the up-down direction rather than swinging in the left-right direction when tightening the screws, and the gun body is prevented from hitting the wrist. The multifunctional screw locking device is high in practicability, wide in application range and high in safety.

Description

technical field [0001] The invention belongs to the technical field of automobile assembly tools, and in particular relates to a multifunctional screw locking device for automobile seats. Background technique [0002] As people's requirements for the convenience of tools are getting higher and higher, the design of electric screw guns is obviously more in line with people's needs. A screw gun is a tool used to turn a screw to force it into place, usually with a thin wedge-shaped bit that can be inserted into the slot or notch of the screw head. The screw gun is used in people's daily life to repair or disassemble various Common tools for electrical equipment. [0003] Existing electric screw guns generally can only lock or disassemble one type of screw; and in the assembly process of car seats, two electric guns are usually required to lock the hexagonal screws and hexagonal wedge screws on the car seat , due to the different shapes of the gun heads used by different screw...

AI Technical Summary

Problems solved by technology

[0003] Existing electric screw guns generally can only lock or disassemble one type of screw; and in the assembly process of car seats, two electric guns are usually required to lock the hexagonal screws and hexagonal wedge screws on the car seat , due to the different shapes of the gun heads used by different screws, the assembler needs to identify the type of seat and use the corresponding screw gun. work efficiency

[0004] At the same time, when using an electric screw gun to tighten the screws of the car seat, the screw gun is usually manually held. Since the screw gun has a certain weight, the worker is prone to fatigue when holding the screw gun for a long time, resulting in a reduction in work efficiency. Moreover, When the screw is tightened, the gun head is easy to swing, and the gun head hits the wrist, thus causing injury to the worker
