Description

Technical Field

[0001] The invention belongs to the technical field of profile processing equipment, and in particular relates to a numerically controlled angle code guiding mechanism and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of profile assembly, it is common to use angle brackets to connect fixed profiles with adjacent profiles. In the traditional profile assembly process, since the angle brackets and the inner cavity of the profile are clearance-fitted, after the angle brackets are placed at both ends of the inner cavity of the fixed profile, there is an inevitable inclination between the plane and the horizontal direction, which makes it difficult to coincide with the horizontal plane of the corresponding inner cavity of the adjacent profile. The prior art publication number CN218347253U provides a guide angle bracket, which realizes the posture correction of the angle bracket through a guide screw hole. This guide angle bracket is an angle bracket with a special structure, but for ordinary angle brackets, the prior art does not consider a mechanism for automatically correcting the posture of the angle steel sheet, so that during the actual assembly of the profile, it is necessary to use tools to semi-automatically adjust the position and angle of the angle steel sheet. The operation process is not only cumbersome and inefficient, but also difficult to ensure the accuracy and consistency of the assembly. Summary of the invention

[0004] In view of the above problems, the present invention provides a CNC angle code guiding mechanism and a working method. By controlling the support rod mechanism, the upper plane of the guide block is made to coincide with the lower planes of the inner cavities of two adjacent profiles, ensuring that the adjacent profiles can be smoothly inserted into the angle codes at both ends of the fixed profiles, thereby achieving high-precision correction of the angle codes and automatic splicing of the profiles, thereby improving assembly efficiency and consistency.
