Pneumatic device for assembling back surface sleeve of automobile and assembly method thereof

Abstract

The invention discloses a pneumatic device for assembling a back surface sleeve of an automobile and an assembly method thereof. The pneumatic device comprises a turnover bracket (2), a upper groove and tongue plate (1) and a turnover plate (6), wherein the upper groove and tongue plate (1) and the turnover plate (6) are fixed on the turnover bracket (2); an upper groove and tongue plate (1) opposite to the upper groove and tongue plate (1) is arranged at one end of the turnover plate (6); a push air cylinder (5) is arranged at the other end of the turnover plate (6); a push block on the push air cylinder (5) can move in a sliding chute comprising the upper groove and tongue plate (1) and the lower groove and tongue plate (10); the turnover plate (6) can be fixed on the turnover bracket (2) by a turnover shaft (4); and the turnover plate (6) is pushed by the pneumatic device arranged at the bottom of the turnover bracket (2) to rotate around the turnover shaft (4). By using the mode of combining the pneumatic structure with the mechanical structure to replace the structure adopting the negative pressure, the device is simple for the whole operation and convenient for maintenance; and in addition, all work procedures have low labor intensity and the production efficiency is high.

Description

technical field [0001] The invention relates to a pneumatic device for assembling automobile components and an assembly method thereof, in particular to a pneumatic device and an assembly method for assembling a rear seat cover of an automobile. Background technique [0002] The backrest of the car is a mechanism that can be turned over in the middle of the backrest of the rear seat of the car. Its function is: turn it up in place, form a whole with the backrest, and play the role of a backrest; turn it down 90 degrees in place, it can be used as a seat for the left and right passengers The armrest is also used as a teacup holder in some models, which brings convenience to the occupants. [0003] The support and hinge mechanism of the backrest of the car is a steel structure, most of which are foam in the middle, and the outer surface is covered with a surface cover. Due to the use of the backrest of the car, its cover is different from the cover of other parts of the seat,...

Problems solved by technology

However, this assembly method has the following disadvantages: 1. The cost of the negative pressure system is high, maintenance is troublesome, and the sealing of the plastic sleeve is cumbersome; 2. The plastic sleeve cannot be taken out after the assembly is completed, which not only increases the cost but also affects the use effect; 3. It takes a long time for the negative pressure to be generated and completed, so the production efficiency is not high
