Embodiment 1

[0031] As shown in Fig. 1 and Fig. 2, on the basis of the above-mentioned technical solution, the cross-sectional shape of the mating surface of the supporting arm fixing frame 5 and the movable supporting arm 3 using a clearance fit according to the present invention is rectangular. The movable support arm 3 is inserted into the rectangular hole of the support arm fixed mount 5 and forms a clearance fit. The movable support arm 3 can be freely expanded and contracted in the rectangular hole of the supported arm fixed mount 5, and will not rotate during the telescopic process, so that the support arm The position of the block 2 on the straight line of motion will not change due to movement, ensuring that it can hold up the vehicle body reliably.

Embodiment 2

[0033] As shown in Figure 2, on the basis of Embodiment 1, the rear transverse boom 8 of the present invention is provided with a stroke adjuster 4, and the stroke adjuster 4 is located between the bracket arm fixture 5 and the movable bracket arm. 3 is provided with a rack and pinion transmission mechanism 9, and the transmission direction of the rack and pinion transmission mechanism 9 is to make the movable support arm 3 stretch out or retract on the support arm fixed frame 5. The rack and pinion transmission mechanism 9 is used to adjust the position of the movable support arm 3, which is convenient to operate, labor-saving, easy to control, accurate in positioning, and the structure occupies a small space.

Embodiment 3

[0035] As shown in Figure 2, the structure of the rack and pinion transmission mechanism 9 described in the above-mentioned embodiment is: a rack 7 is set on the body of the movable support arm 3, and a gear 6 is established on the support arm fixed frame 5. The gear 6 is supported by the stroke adjuster bracket 10 provided on the stroke adjuster 4 through the gear adjustment shaft 11, and the gear 6 and the rack 7 are meshed with each other. This setting scheme mainly considers the support of the gear 6 conveniently, and it is also convenient to use the gear 6 to carry out the adjustment operation.

Abstract

The invention discloses an automobile production line lifting tool and comprises a suspender, a front transverse lifting arm and a back transverse lifting arm (8). The back transverse lifting arm (8) is provided with a corbel fast headstock (5) and a movable corbel (3). The movable corbel (3) is inserted in the corbel fast headstock (5) to form clearance fit. The extension end of the movable corbel (3) is provided with a follow block (2). The back transverse lifting arm (8) is provided with a movable corbel fixer (1) which can fasten or loose the corbel fast headstock (5) and the movable corbel (3). The above mentioned technical scheme ensures that the automobile production line lifting tool has the ability of quick, flexible and accurate adjustment to adapt to mixing line production of different vehicle styles. The invention also discloses a regulation method adopted by the automobile production line lifting tool.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to automobile production process equipment in this field. More specifically, the invention relates to a hanger for an automobile production line. In addition, the present invention also relates to the adjustment method adopted by the above-mentioned automobile production line hanger. Background technique [0002] In the production line, automobile manufacturing enterprises use spreaders to lift the car body for processing and assembly operations. At present, the rear support arm of the domestic automobile spreader basically stays on the rear support block support plate directly welded on the rear support arm, which makes it difficult for the spreader to adapt to the changing needs of multiple models. That is to say, the automobile spreader of the current production line cannot directly and effectively adapt to the mixed line production of multiple models. At present...
