Description

Double-layer cross hinge frame

Technical Field

The utility model relates to a support frame technical field especially is used for the hydro-cylinder, specifically is a double-deck cross hinge frame.

Background

A double-layer cross hinge frame is used for supporting an oil cylinder and enabling the oil cylinder to have a bidirectional rotating function and structurally comprises a lower layer support and an upper layer support hinged with the lower layer support, wherein a cross hinge frame box body is arranged on the upper layer support and used for hinging the oil cylinder, so that the oil cylinder can adapt to certain installation deviation, and a piston rod is prevented from being subjected to lateral force.

Generally, the cross-hinge box body is formed by welding 16 plates, as shown in fig. 4, a welding position 24 is required, which not only consumes more welding materials, but also causes large deformation generated by welding, and brings more welding defects; the corners of the cross-shaped hinge frame box body are right angles, so that stress is more concentrated, and mechanical performance is reduced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the cross-shaped hinge frame box solves the technical problems of high manufacturing cost, poor quality and low mechanical property of the traditional cross-shaped hinge frame box.

The utility model provides a double-layer cross hinge frame, which comprises a lower layer bracket and an upper layer bracket hinged with the lower layer bracket, wherein the upper layer bracket comprises a box body, oil cylinder supports are arranged at the opposite ends of the box body, and a supporting hinge shaft is hinged between the oil cylinder supports;

the box body comprises a first bending plate and a second bending plate, the first bending plate and the second bending plate are in a shape of a Chinese character 'hui' and are formed by welding, the first bending plate is sleeved on the outer side of the second bending plate, the upper ends of the first bending plate and the second bending plate are connected with an installation plate, and the installation plate is used for installing the oil cylinder support; the corner of the box body is arc-shaped.

The first bending plate and the second bending plate are arranged, and can be formed only by two welding seams, so that not only are the consumables reduced, but also the welding workload of workers is reduced, the manufacturing time is saved, and the cost is saved; the four corners of the box body are arc-shaped, so that the strength of the box body is improved, and the stress concentration coefficient is reduced, thereby avoiding the reduction of the mechanical property of the box body.

Furthermore, a plurality of rib plates are connected between the first bending plate and the second bending plate. The rib plates are used for increasing the strength of the box body, so that the box body is not easy to deform.

Furthermore, the welding points of the first bending plate and the second bending plate are both arranged at the straight edge. The welding point is arranged at the straight edge, so that the operation of workers is facilitated, and the shape of the bent plate after welding is stable.
