Machining device special for sectional material

Abstract

The invention provides a machining device special for a sectional material. The machining device comprises a clamp used for clamping the sectional material and a machining part used for conducting secondary machining on the sectional material. The clamp comprises an installation base and a clamping mechanism arranged on the installation base. The clamping mechanism comprises clamping parts which are arranged in a pairing manner along the central axis of the installation base. The machining part comprises a work head, a work arm and a lifting main shaft, an auxiliary positioning device is arranged at the position, corresponding to the work arm, of the lifting main shaft and comprises a sliding supporting arm, the sliding supporting arm is provided with a clamping plate, and the clamping plate is provided with a positioning hole. It can be known from the above technical scheme that the positioning hole used for assisting in drill bit positioning is formed in the position, corresponding to the diameter and the position of a drill bit, on the clamping plate, the drill bit drilling machining precision can be improved, meanwhile, the machining part of the sectional material can also be supported through the clamping plate, and sectional material deformation generated in the drilling machining process is avoided.

Description

technical field [0001] The invention relates to the field of processing tools, in particular to a special processing device for profiles. Background technique [0002] Profiles are widely used in the field of construction and mechanical structures. The construction speed of profiles is fast, the floor space is small, and it is suitable for all-weather construction, which is less affected by climate conditions. The construction speed of the steel profile is about 2-3 times of the construction speed of the concrete structure, the capital turnover rate is doubled, and the financial cost is reduced, thereby saving investment. [0003] In the actual use process, the profile needs secondary processing such as punching and cutting. Due to the special structure of the profile, there is an empty groove on the profile, so that there is no support device inside the profile at some positions, and no internal support can be obtained. When these parts are drilled with tools in the prior ...

Problems solved by technology

[0003] In the actual use process, the profile needs secondary processing such as punching and cutting. Due to the special structure of the profile, there is an empty groove on the profile, so that there is no support device inside the profile at some positions, and no internal support can be obtained. When these parts are drilled with tools in the prior art, the profile will be deformed to varying degrees, which will reduce the mechanical properties of the profile and adversely affect the quality of the building or the structure of the machine.
