Description

Technical Field

[0001] The utility model relates to the field of numerical control machining, in particular to an automatic clamping induction device for a numerical control machining center machine tool. Background Art

[0002] CNC machining refers to a process method for machining parts on CNC machine tools. CNC machining refers to the process in which the control system issues instructions to make the tool perform various movements that meet the requirements, and the shape and size of the workpiece and other technical requirements and processing technology requirements are expressed in the form of numbers and letters. It generally refers to the process of machining parts on CNC machine tools, and is a mechanical machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as a wide variety of parts, small batches, complex shapes, and high precision, and to achieve efficient and automated processing;

[0003] When machining parts on CNC machine tools, the basic principle of positioning and installation is to reasonably select the positioning reference and clamping scheme. When selecting, attention should be paid to the unification of the design, process and programming calculation reference; the number of clamping should be reduced as much as possible, and all the surfaces to be machined should be machined after one positioning and clamping; avoid the use of manual adjustment processing schemes that occupy the machine to give full play to the efficiency of CNC machine tools.

[0004] The characteristics of CNC machining put forward two basic requirements for fixtures: one is to ensure that the coordinate direction of the fixture is relatively fixed with the coordinate direction of the machine tool; the other is to coordinate the dimensional relationship between the coordinate system of the part and the machine tool. In addition, it is also necessary to consider that when the batch size of parts processing is not large, combined fixtures, adjustable fixtures and other general fixtures should be used as much as possible to shorten the production preparation time and save production costs; special fixtures should be considered in batch production, and the structure should be simple; the loading and unloading of parts should be fast, convenient and reliable to shorten the downtime of the machine tool; the components on the fixture should not hinder the machine tool from processing the various surfaces of the parts, that is, the fixture should be open, and its positioning and clamping mechanism components should not affect the tool path during processing;

[0005] At present, the fixtures on CNC machine tools can only clamp parts of a certain type or size. When processing another batch of parts, the fixtures need to be readjusted or the fixture accessories need to be replaced. The parts processing efficiency is greatly reduced and the operation is relatively complicated. This application aims to set up multiple types of fixture accessories at the same time, classify and clamp different types of parts during CNC processing, and perform diversified clamping on parts of different sizes that require different clamping methods, so as to achieve precise positioning of the processed parts, meet the clamping of parts of different sizes, and improve the flexibility of CNC part clamping.
