Description

Technical Field

[0001] The utility model relates to the technical field of automobile lifting eye processing equipment, in particular to a limiting device for automobile lifting eye processing. Background Art

[0002] During the production process of the automobile front spring lifting ear bracket assembly, the automobile lifting ear needs to be limited and fixed. In the existing technology, the limitation of the automobile lifting ear is often relatively simple, and the automobile lifting ear is not fixed well by clamping in a single direction. At the same time, there is no function of quickly limiting and fixing automobile lifting ears of different specifications, and the fixed automobile lifting ear cannot be rotated to facilitate subsequent processing operations.

[0003] For example, the authorized patent document with application number 202120682947.0 discloses a drilling and fixing device for the ear of the front steel plate of an automobile, comprising a base, a drilling template, a drilling template support seat, a workpiece receiving pin one, a workpiece receiving pin two, a workpiece receiving pin three, a lever clamping device, a positioning block, a locking bolt and a locking bolt fixing block, wherein the locking bolt passes through the upper part of the locking bolt fixing block, and a lever clamping device is provided directly in front of the workpiece receiving pin two, and the lever clamping device consists of a bolt, a pressure block and a support pin. The utility model fixes the movable ear in the vertical direction by using the lever clamping device, and the positioning device and the locking bolt fix the movable ear in the horizontal direction. The clamping and fixing of the movable ear is simple and convenient, thereby improving production efficiency. In addition, a drilling hole on the drilling template is specially provided. During the drilling process, the drill bit passes through the drilling template hole to drill the movable ear. The drilling template hole can reduce the swing amplitude of the drill bit, thereby ensuring the drilling processing accuracy of the movable ear.

[0004] The above patent has the problem that the automobile lifting eye is limited by clamping in a single direction, and the automobile lifting eye cannot be rotated after being fixed to facilitate subsequent processing operations. Therefore, we need to provide a limiting device for automobile lifting eye processing. Utility Model Content
