Description

Technical Field

[0001] The utility model relates to the technical field of frame processing, and specifically relates to a grasping device applicable to frames of different specifications. Background Technique

[0002] Frame processing refers to the process of processing raw materials into complete frames. As the skeleton of an automobile, the frame undertakes the important functions of supporting the vehicle body and transmitting power. Its processing technological process is complex and requires high precision. After the frame is formed, surface treatments such as painting and galvanizing are often required for the frame to improve the corrosion resistance and aesthetics of the frame. In order to facilitate the surface treatment of the frame, it is often necessary to fix and lift the frame.

[0003] Currently, when fixing and lifting the frame, it is often necessary to use iron chains to bundle and fix the frame, and then lift the frame. This fixing method is not only very cumbersome, but also has low stability. At the same time, using iron chains is not convenient for fixing frames of different sizes, and the parts of the frame surface in contact with the fixing mechanism are not convenient for workers to process, affecting the processing efficiency of the frame. Therefore, it is necessary to design a grasping device applicable to frames of different specifications to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a grasping device applicable to frames of different specifications to solve the problems raised in the above background technique.

Electric telescopic rods are fixedly installed on both the front side and the rear side of the bottom of the top plate. The bottom end of the electric telescopic rod is fixedly installed with a traction plate. A motor is fixedly installed on the left side of the traction plate through a bracket. The output shaft of the motor is fixedly installed with a bidirectional threaded rod through a coupling. Threaded sleeves are threadedly connected to both sides of the surface of the bidirectional threaded rod.

[0006] The bottom of the threaded sleeve is fixedly installed with a traction rod. L-shaped rods are fixedly installed on both the front side and the rear side of the bottom of the traction rod. The bottom end of the L-shaped rod penetrates through the traction plate and extends to the outside of the traction plate. One end of the L-shaped rod is fixedly installed with a triangular plate.

[0007] Preferably, support plates are fixedly installed between the two L-shaped rods on the same side and the two triangular plates. Drums are rotatably connected between the front side and the rear side of adjacent two support plates through bearing parts.

[0008] Preferably, a chute plate is fixedly installed on the surface of the electric telescopic rod through a bracket. Sliders are slidably connected to both sides inside the chute plate.

[0011] Preferably, movable openings for cooperating with the L-shaped rods are formed at the front side and the rear side of both sides of the top of the traction plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For the grasping device applicable to frames of different specifications, by controlling the motor to start, the motor drives the L-shaped rods on both sides to move towards the middle simultaneously. The movement of the L-shaped rods drives the triangular plate, the support plate and the roller to move. After the L-shaped rods move above the roller, control the electric telescopic rod to contract, so that the electric telescopic rod drives the roller to rise. At this time, the frame can be lifted by the roller, achieving the effect of facilitating the surface treatment of the frame. And by setting the roller, after the frame is lifted, it can slide back and forth through the roller, thereby achieving the effect of facilitating the treatment of the position where the frame contacts the roller, improving the processing efficiency of the frame.

[0014] 2. For the grasping device applicable to frames of different specifications, by setting the pressing plate and continuing to control the electric telescopic rod to contract after the frame slides to a proper position, the electric telescopic rod can continue to drive the traction plate to rise. At this time, the traction plate drives the roller and the frame on its top to rise. When the top of the frame contacts the anti-slip grooves formed at the bottom of the pressing plate, the effect of limiting the slid frame can be achieved, further improving the stability during the surface treatment of the frame.
