Description

Technical Field

[0001] The utility model relates to the technical field of profile clamps, in particular to a fixing clamp for profile processing. Background Art

[0002] Profiles are widely used in the door and window industry. During the processing, they are usually clamped and fixed with clamps for stable processing. However, due to the special application locations and unconventional shapes of some profiles, the clamps used for commonly used profiles are clamped on their fixed edges for stability, while special-shaped aluminum profiles can only be fixed with special clamps that match their shapes. Different clamps need to be replaced for processing different aluminum profiles, which is relatively troublesome.

[0003] A fixing fixture for processing special-shaped aluminum profiles with publication number CN217572576U comprises a bottom clamp frame, a lifting screw, a lifting frame, a rotating cavity column, a clamp frame and an upper clamp bar column. A screw rotation hole is provided on the top of the bottom clamp frame, and the lifting screw is rotatably installed in the screw rotation hole through a screw bearing. The lifting frame is screwed on the lifting screw. The rotating cavity column is fixedly installed on one side of the lifting frame. A rotating cavity groove is provided on one side of the rotating cavity column. A frame shaft is rotatably installed in the rotating cavity groove through an inner cavity bearing. One end of the frame shaft extends to the outside of the rotating cavity column and the clamp frame is fixedly installed. The frame of the clamp frame is provided with bar column frame holes, and a pressure strip screw is screwed on the frame of the clamp frame. The beneficial effect is that the utility model realizes the clamping of aluminum profiles in multiple directions through the adjustment of lifting and angle, and realizes the clamping of profiles of different shapes in different positions through the adjustment of multiple groups of bars, and has a wide range of applications. In addition, the existing profile clamps also have the following disadvantages during use:

[0004] (1) Existing profile clamps only tighten the profile by dropping the bar to abut against the profile, lacking a buffer part. Many existing profiles have a relatively soft surface, and direct abutment can easily cause hard contact and damage the profile surface;

[0005] (2) The existing profile clamp is not provided with a lifting structure. When processing the profile, due to different processing requirements and different equipment, the relative height between the profile and the processing equipment needs to be adjusted. Without a lifting structure, the only option is to adjust the processing equipment, which is inconvenient to use. Utility Model Content
