Background

In the automobile coating production process, the automobile body needs to be conveyed mechanically in the whole line, and the automobile body needs to be fixed and unchanged in position on a lifting appliance and a skid. At present, automobile factories adopt a mode of designing a positioning fulcrum on a lifting appliance or a skid, and an automobile body is fixed by utilizing an automobile body fabrication hole and the fulcrum of the lifting appliance or the skid. The advantages of this positioning are that the relative position tolerance of the body and the spreader or skid is small, and the body is stable, and therefore has been used to date.

The domestic autonomous automobile brand can not realize the platformization of various products at present, and when various automobile types are produced in the same production line in a collinear mode, the supporting points are difficult to share due to different positioning positions. This results in a plurality of positioning points on the spreader or skid, which increases the weight of the spreader or skid, increases the abrasion burden of the conveying system, and increases the energy consumption cost during baking. Meanwhile, the difficulty and investment cost of transformation of the positioning pivot during the import of the new vehicle type are invisibly increased.

Detailed Description

The utility model is further illustrated below with reference to the accompanying figures 1-2:

the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, the present invention provides a switchable positioning fulcrum for multiple vehicle types based on the prior art, which comprises: eccentric handle 6, supporting seat 2, eccentric shaft 1, first handle jump ring 5, second handle jump ring 3 and bottom plate 4, supporting seat 2 passes through welded fastening on bottom plate 4, and bottom plate 4 is fixed on the connecting plate of hoist or skid through full thread hexagon bolt, plain washer, standard type spring washer and hexagon nut. The first handle clamp spring 5 and the second handle clamp spring 3 are identical in structure and are symmetrically arranged on two sides of the supporting seat 2.

The eccentric shaft 1 comprises a large ring platform 12, a positioning rod 11 and a connecting rod 13 which are arranged on two sides of the large ring platform 12, the positioning rod 11 and the connecting rod 13 are not coaxial, the positioning rod 11 is coaxial with the large ring platform 12, the upper half part of the positioning rod 11 is conical, and the lower half part of the positioning rod is cylindrical. Connecting rod 13 is fixed at the border of big ring platform 12, is equipped with the through-hole on the supporting seat 2, and eccentric shaft 1 passes the through-hole through connecting rod 13 and ends in big ring platform 12 and the one end of eccentric handle 6 and pass through bolted connection together, and connecting rod 13 external diameter is less than or equal to the internal diameter of through-hole.
