Description

Technical Field

[0001] The utility model relates to the technical field of box body turnover, and specifically discloses a turnover device for box body processing. Background Art

[0002] At present, during the production process of bulldozer boxes, it is basically single-process production. After the box body milling surface is completed, workers use a crane to hoist the box body to the work position appliance manually. The operator manually cleans the iron filings and burrs generated during the processing inside the box body, and then transfers the workpiece to the next process for subsequent processing. The box body needs to be transferred multiple times, and the turnover distance is long. Moreover, during the processing of the box body, after it needs to be turned 90°, it needs to be clamped again to process the other side of the box body. When the box body is turned over, workers use a lifting tool, which easily causes the box body to be bumped.

[0003] To solve the above problems, the patent with the publication number CN211520834U discloses an L-shaped turnover machine, including a base and an L-shaped turnover frame arranged on the base. The L-shaped turnover frame includes a horizontal frame and a vertical frame. A first roller conveyor table is arranged on the horizontal frame. A first driving motor is arranged outside the first roller conveyor table. An upper rack is welded to the bottom of the first roller conveyor table. A lower rack corresponding to the upper rack is welded on the horizontal frame. A gear is arranged between the upper rack and the lower rack. A first cylinder is also fixedly connected to the bottom of the first roller conveyor table. The piston rod of the first cylinder is connected to the gear. A second roller conveyor table is arranged on the vertical frame. A second driving motor is arranged outside the second roller conveyor table. Two parallel second slide rails are welded on the vertical frame. A second cylinder is arranged between the second slide rails.

[0004] In the above solution, although the automatic turnover of the box body can be realized. However, when turning over a bulldozer box body with a relatively large weight, the connection between the horizontal frame and the vertical frame and the hinge connection between the L-shaped turnover frame and the base are not firm enough, which easily causes the L-shaped turnover frame to deform and crack, affecting the subsequent grasping of the manipulator during the automatic production of the box body; moreover, in this solution, the clamping assembly is set complexly and the cost is relatively high. Furthermore, the actions of the two cylinders cannot be completely simultaneous, which also easily causes the deformation of the L-shaped turnover frame. Content of the Utility Model
