Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a horizontal flexible multi-station tooling positioning structure. Background Art

[0002] Multi-station tooling positioning is a technology that accurately positions and clamps workpieces during processing or assembly. It is usually used for products that need to be processed or assembled at multiple stations to ensure that each station can accurately operate the workpiece. The automotive expansion valve is an important component in the automotive air conditioning refrigeration system. Its function is to throttle and reduce the pressure of the high-pressure liquid refrigerant from the condenser to become a low-temperature and low-pressure liquid refrigerant so that it can enter the evaporator for evaporation and heat absorption. The automotive expansion valve needs to process multiple surfaces during processing, so it needs multiple positioning and clamping processes.

[0003] Patent No. CN202321565708.2 proposes a multi-station simultaneous clamping and positioning tooling, in which a placement table is fixed to a base, and the placement table has a plurality of placement positions spaced along the X direction, and each placement position has a positioning portion. The multi-station simultaneous clamping and positioning tooling is provided with a plurality of clamping components, each clamping component and a moving part cooperate separately, and an elastic part is provided between the clamping component and the moving part, so that when the moving part moves to the clamping position, each clamping component and the positioning part correspond one by one, and the workpiece can be completed. The clamping action of the workpiece can only be positioned in a single direction when clamping, and a workpiece cannot be clamped and positioned in multiple directions. Each clamp cannot be formed into a separate individual to provide different combination methods to clamp different special-shaped parts, and the clamping range is small. Therefore, technical personnel in this field provide a horizontal flexible multi-station tooling positioning structure to solve the problem that it can only be positioned in a single direction when clamping, and a workpiece cannot be clamped and positioned in multiple directions. Each clamp cannot be formed into a separate individual to provide different combination methods to clamp different special-shaped parts, and the clamping range is small. Utility Model Content
