Vehicle lifting tool

Abstract

The invention relates to a vehicle lifting tool which comprises an upper frame, two sliding plates arranged at the bottom of the upper frame and capable of moving in the length direction of the upper frame, two holding arms arranged at the bottom of each sliding plate and a driving unit used for stretching or retracting the two holding arms. When workpieces are lifted, the distance between the two sliding plates is adjusted to enable the sliding plates to be matched with the workpieces in length, and the distance between the two holding arms arranged below the same sliding plate is adjusted through the corresponding driving unit to enable the holding arms to be matched with the workpieces in width. Compared with the prior art, the distance between the two sliding plates can be adjusted to enable the sliding plates to be matched with the workpieces in length, and the opening degrees of the holding arms are adjusted through the driving units to enable the holding arms to be matched with the workpieces in width so that the lifting tool can be matched with the workpieces of different sizes and models, and the requirement of flexible production is conformed.

Description

technical field [0001] The invention relates to the field of automobile production, in particular to a complete vehicle spreader. Background technique [0002] The flexible production line can effectively reduce production costs and improve production efficiency because it can adapt to multi-model flexible collinearity. At present, the spreader boom used in the automobile production line is multi-position fixed, and the design can be adapted to the vehicle model. When a new model is added, the vehicle spreader needs to be modified. When there are too many models, it is necessary to add a new support for replacement. It has a certain restrictive effect on the expansion of factory models, and also increases the investment in transformation. At the same time, the production efficiency is reduced, the investment cost of fixed assets is increased, and the production capacity is reduced. When a fixed-length body spreader is used, there are risks of skirt deformation, unstable cen...

Problems solved by technology

At present, the spreader boom used in the automobile production line is multi-position fixed, and the design can be adapted to the vehicle model. When a new model is added, the vehicle spreader needs to be modified. When there are too many models, it is necessary to add a new support for replacement. It has a certain restrictive effect on the expansion of factory models, and also increases the investment in transformation

At the same time, the production efficiency is reduced, the investment cost of fixed assets is increased, and the production capacity is reduced. When using a fixed-length body spreader, there are risks of skirt deformation, unstable center of gravity, body falling, and more potential safety hazards.
