Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to a quick-locking clamping structure of a cutting machine. Background Art

[0002] As a commonly used cutting equipment, cutting machines are widely used in production. With the continuous development of modern mechanical processing industry, the requirements for cutting machines are also constantly increasing. Due to the need for work efficiency, the workpiece to be cut needs to be quickly fixed. The clamping mechanism is a common mechanism used to position the workpiece to be cut. It is generally divided into two parts, one is the positioning structure and the other is the clamping structure. When the cutting machine is in use, the fixed plate of the positioning mechanism is used for the workpiece to be abutted during cutting, and the fixed plate also has the function of adjusting the cutting angle of the cutting machine, that is, it serves as an angle plate. Generally, the fixed plates are fixed to the base of the cutting machine by tightening bolts, but when adjusting, you need to loosen the fixing bolts first, then adjust the setting angle of the fixed plate, and then tighten it.

[0003] With the development of the building materials industry, the materials and sizes to be cut are diversified, including metal pipes, angle steels, channel steels, etc., and the shapes also include round pipes, triangular pipes, square pipes, etc. The current clamping mechanism is slow when switching and positioning the workpiece size, and cannot be locked quickly. The clamping device is prone to displacement during the locking process, resulting in loose locking. It is also impossible to quickly clamp and cut workpieces of various shapes of pipes, which will reduce work efficiency.

[0004] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a cutting machine quick-lock clamping structure with a simple structure. Utility Model Content
