Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to a clamping device for automobile trial-produced accessories. Background Art

[0002] Auto parts are important components of the various units that make up the whole car. Among them, there are many auto parts with complex shapes and complex cavities inside. When these parts are mass-produced, they are generally produced by casting, and only the corresponding molds are needed. However, in the early stage of research and development and trial production of these parts, since the structure has not yet been determined and the quantity demand is small, it is very impractical to open the mold at this time if the cost is extremely high. At present, when trial-producing the above-mentioned parts, most of them use machining center machine tools to carve aluminum ingots into the required shape. This processing method requires milling and removing the excess parts on the aluminum ingots little by little. Although the working hours are long, by comparison, the cost and processing cycle of small batch trial parts using this processing method are still much lower than mold casting.

[0003] However, there is a problem with the milling and engraving method using a machining center, that is, the clamping and positioning of the aluminum ingot is very difficult. Using traditional press-fit fixation, the fixture will hinder the milling path of the tool, and multiple clamping has to be performed, but multiple clamping will increase processing errors. Now a considerable number of processing personnel use glue to bond the aluminum ingot to the machine tool plate. Although the above problem is solved, the glue bonding is not reliable and often breaks off, which not only damages the workpiece and equipment, but is also very dangerous. Therefore, it is very necessary to propose a special clamping device.

[0004] Therefore, in view of the deficiencies of the above-mentioned technologies, the present application proposes a clamping device for automobile trial-produced accessories that can effectively solve the above-mentioned technical problems. Utility Model Content

When positioning, the contact area of ​​this device with the aluminum ingot is small and concentrated at the lower end, which does not affect the milling processing of the machine tool, avoids the problem of multiple clamping, improves the processing accuracy and efficiency, and is very suitable for machine tool processing of automotive trial parts.
