Description

Technical Field

[0001] The utility model belongs to the technical field of automobile trim strip processing, in particular to a milling tool for automobile trim strips. Background Art

[0002] Car decorative strips are mainly used in the car compartment, on the door or other parts for decoration and sealing. There are many burrs on the decorative strips after molding, and the dimensional accuracy of the decorative strips is relatively low, so the decorative strips need to be milled.

[0003] In the traditional milling process of trims, the accuracy of part positioning of the milling tooling cannot be guaranteed, which often leads to the accumulation of deviations during the processing, directly affecting the final accuracy and consistency of the product. In addition, due to the inherent characteristics of uneven extrusion thickness of profile aluminum materials during the production process, this factor further exacerbates the complexity of the milling process. Specifically, when the milling tool faces aluminum materials with uneven thickness, it is easy to have uneven milling depths - that is, some areas are milled too deep, while other parts may not be milled enough. This "deep milling and shallow milling" problem directly leads to the volatility and instability of product quality. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a milling tool for automobile trims, which eliminates the problem of low product precision caused by positioning tolerance during the milling process of aluminum profiles. The milled profile surface always uses the inner surface as the reference plane, and does not cause quality problems such as deep or shallow milling, thereby improving the processing accuracy of automobile trims.

[0005] The utility model is implemented as follows: a milling tool for automobile trim strips comprises a bottom plate, wherein the upper end surface of the bottom plate is provided with at least three sets of fixing mechanisms along the length direction of the bottom plate, wherein two sets of fixing mechanisms are respectively provided on the bottom plate near the side wall of the bottom plate;

[0006] The fixing mechanism includes a mounting frame, an upper clamping cylinder is arranged in the mounting frame, a lower cavity block is arranged at the end of the piston rod of the upper clamping cylinder through a fixing plate, the upper end surface of the lower cavity block is provided with a trim cavity for placing the automobile trim, the upper plate of the mounting frame is provided with an upper cavity block, the upper cavity block is arranged opposite to the lower cavity block, and the lower end surface of the upper cavity block is provided with a fixing block for fixing the automobile trim.

[0007] Furthermore, the fixing mechanisms at both ends are provided with positioning mechanisms for positioning the ends of the trim strips, the positioning mechanisms include a positioning block arranged on a fixing plate, one end of the positioning block extends toward the end of the automobile trim strip and is provided with an end cavity, an outer wall of the positioning block is provided with an end clamping cylinder, a pressing plate is provided on the piston rod of the end clamping cylinder, and a pressing block corresponding to the end cavity is provided on the lower end face of the pressing plate.

[0008] Furthermore, a mounting long hole is provided on the fixing plate in the end fixing mechanism along the length direction of the automobile trim strip, and the positioning block is adjustably mounted on the fixing plate through the cooperation of the fastener and the mounting long hole. When the positioning block needs to be removed or replaced, the positioning block can be easily removed from the mounting long hole by simply loosening the fastener, thereby achieving quick disassembly and assembly and simplifying the maintenance process; at the same time, the mounting long hole can be used to adjust the installation position of the positioning block to adapt to automobile trim strips of different lengths or shapes, thereby improving its versatility and scope of application.

[0009] Furthermore, a forklift sleeve for forklift to pick up is provided on the bottom plate, so that the forklift can pick up and carry it easily and quickly, reducing the need for manual handling and improving the overall transportation efficiency.

[0010] The utility model has the following advantages and technical effects: Due to the adoption of the above technical scheme, the problem of low product precision caused by positioning tolerance during the milling process of aluminum profiles is eliminated, the milled profile surface always uses the inner surface as the reference plane, and quality problems such as deep or shallow milling will not occur, thereby improving the processing accuracy of automobile trims.
