Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile manufacturing, in particular to a clamping device used for CNC processing of aluminum profiles. Background Art

[0002] Aluminum profiles refer to solid straight bars of aluminum that have been formed through plastic processing and have a certain cross-sectional shape and size. According to the cross-sectional characteristics, profiles can be divided into simple cross-sectional profiles and special-shaped end face profiles. For special-shaped profiles, their cross-sections usually have obvious concave and convex branches, so that the profiles will have multiple profiles. In the processing of traditional complex multi-faceted aluminum alloy special-shaped profiles, such as profiles for automobile bodies, manufacturers usually divide the special-shaped surfaces into several sub-faces for step-by-step or process-by-process processing. Obviously, this will easily cause processing deformation and affect the processing accuracy, ultimately resulting in low production efficiency, high defective rate and scrap rate.

[0003] To overcome the above problems, some manufacturers currently use single-sided batch processing before the next batch processing. However, although this method can improve production efficiency to a certain extent, the processing procedures are cumbersome and the quality risk is greatly increased;

[0004] In addition, some manufacturers use split fixtures for faceted batch processing, but this method has high manufacturing costs, complex structure of processing equipment, low efficiency and benefits, and still cannot reflect the practicality, economy and efficiency of fixtures for the processing of large quantities of multi-faceted complex aluminum alloy profiles;

[0005] Especially in the CNC processing process, CNC processing usually refers to computer digital controlled precision machining, including CNC lathes, CNC milling machines, CNC boring and milling machines, etc., which have high processing efficiency, but the specifications and models of aluminum profiles processed by each CNC machine tool are single, and the adaptability to continuous processing of multiple aluminum profiles is not strong. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and to provide a clamping device for CNC processing of aluminum profiles, which is suitable for the processing and production of various aluminum profiles.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A clamping device for CNC processing of aluminum profiles, comprising a base; a first clamping component is provided on the base;

[0009] The first clamping component includes more than two groups of first supporting components arranged on the base; a first positioning component is provided on the base outside the first supporting component at one end, and a first clamping component is provided on the base outside the first supporting component at the other end, a second positioning component is provided on the base on one side of the first supporting component, a second clamping component is provided on the base on the opposite side of the second positioning component, and a third clamping component is provided on the base on the same side of the second clamping component.

[0010] A further preferred technical solution is that a second clamping component is provided on the base on one side of the first clamping component; or a second clamping component is provided on the other side of the base opposite to the first clamping component.

[0011] A further preferred technical solution is that the second clamping component includes more than two groups of third support components arranged on the base; a third positioning component is provided on the base on the outer side of the third support component at one end, and a fourth clamping component is provided on the base on the outer side of the first support component at the other end, a fourth positioning component is provided on the base on one side of the first support component, a fifth clamping component is provided on the base on the same side of the fourth positioning component, and a sixth clamping component is provided on the base on the opposite side of the fourth clamping component.

[0012] A further preferred technical solution is that a second supporting assembly is provided on the base between the first supporting assemblies.

[0013] A further preferred technical solution is that the second support assembly includes a plurality of rectangular support members, which are arranged in a row on one side of the aluminum profile, a U-shaped rib is provided at the upper end of the rectangular support member close to the outer side of the aluminum profile, and an open groove is also provided on the upper end surface of the rectangular support member.

[0014] Compared with the prior art, the utility model has the following beneficial effects: it is suitable for the processing and production of various aluminum profiles, has high production efficiency, low manufacturing cost, strong adaptability, can meet the requirements of processing accuracy and processing deformation, has high yield rate and is conducive to mass production;

[0015] Special fixtures are made for complex and multi-faceted profiles to be processed, thereby achieving one-piece clamping, quick clamping and avoiding repeated processing on multiple surfaces or at multiple stations, greatly simplifying the structure of the processing equipment for multi-faceted profiles, improving production efficiency, reducing manufacturing costs, and increasing the yield rate of finished profiles. It is scalable for the processing of complex, special-shaped, multi-faceted profiles and can achieve mass production. BRIEF DESCRIPTION OF THE DRAWINGS
