Problems solved by technology

At present, the rear support arm of the domestic automobile spreader is basically still welded directly to the rear support arm with the support plate of the rear support block, which makes it difficult for the spreader to adapt to the needs of multiple vehicle 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, the bracket support plate of the auto spreader on the automobile production line is directly welded and fixed to the bracket arm of the spreader. This fixed connection method will easily lead to deviations in the relative positioning of the bracket and the side skirt of the vehicle body, which can only be rough. The relative positioning of the ground, this kind of rough relative positioning makes the car body sometimes cannot be completely hoisted by the spreader, which is easy to cause safety accidents and affects the assembly quality of the vehicle
[0003] When changing the model of the automobile production line, it is necessary to carry out large-scale transformation of the spreader on the production line in advance. This large-scale transformati

Example Embodiment

[0030] Example 1:

[0031] As shown in FIGS. 1 and 2 , on the basis of the above technical solutions, the supporting arm fixing frame 5 and the movable supporting arm 3 adopting clearance fit according to the present invention have a rectangular cross-sectional shape of their mating surfaces. The movable support arm 3 is inserted into the rectangular hole of the support arm fixing frame 5 and forms a clearance fit. The movable support arm 3 can freely expand and contract in the rectangular hole of the support arm fixing frame 5, and will not rotate during the expansion and contraction process, so that the support arm 3 can be freely retracted. The position of the block 2 on the moving straight line will not be changed due to the movement, so as to ensure the reliability of holding up the vehicle body.

Example Embodiment

[0032] Embodiment 2:

[0033] As shown in FIG. 2 , on the basis of the first embodiment, a stroke adjuster 4 is provided on the rear horizontal boom 8 according to the present invention, and the stroke adjuster 4 is arranged between the support arm fixing frame 5 and the movable support arm. A rack and pinion transmission mechanism 9 is arranged between 3 , and the transmission direction of the rack and pinion transmission mechanism 9 is to make the movable support arm 3 extend or retract on the support arm fixing 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 small in space occupied by the structure.

Example Embodiment

[0034] Embodiment three:

[0035] As shown in FIG. 2 , the structure of the rack-and-pinion transmission mechanism 9 described in the above embodiment is as follows: a rack 7 is provided on the body of the movable support arm 3 , and a gear 6 is provided on the support arm fixing 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 mesh with each other. This arrangement mainly considers the convenience of supporting the gear 6 and also facilitates the use of the gear 6 for adjustment operations.

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...
