Description

Technical Field

[0001] The invention relates to the technical field of milling equipment, in particular to an automatic tool magazine device used on multi-station milling equipment. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. It does not require workers to directly operate the machine tool, but realizes processing by compiling a processing program. In the process of processing, due to the different processing accuracy requirements of different parts, the tool often needs to be replaced during processing. Therefore, setting up a tool magazine on the CNC machine tool has become an indispensable choice for mechanical processing factories. Taking the engraving machine and CNC as examples of CNC machine tools in the prior art, it is to add a tool magazine with a straight-row structure to the engraving machine and set a standby tool holder on the tool magazine. When the tool needs to be replaced, the tool to be replaced is first moved from the spindle to the standby tool holder, and then the tool magazine and the standby tool holder are moved to a position close to the spindle of the engraving machine, and then the spindle of the engraving machine is moved to place the original tool on the spindle into the vacant position, and finally the tool to be installed in the tool magazine is installed on the spindle to complete the tool change operation. Such a CNC machine tool has the following problems because it has to move the entire tool magazine:

[0003] 1. The size of the tool magazine is limited by the size of the precision engraving processing platform, and the tool magazine cannot store more tools;

[0004] 2. The tools in the tool magazine are prone to shaking and tilting during the movement of the tool magazine, resulting in inaccurate tool selection and tool setting by the spindle, thus causing errors in tool processing.

[0005] With the rapid development of intelligent display terminal equipment, various manufacturers continue to launch a new generation of glass screens, among which 2.5D and 3D curved glass have the most fierce momentum and the best market prospects. In the production process of curved glass, grinding and polishing is a very important process, but in the current glass grinding and polishing industry, traditional processing equipment and processes can no longer effectively cope with the grinding and polishing requirements of 2.5D and 3D curved glass, and generally have problems such as low efficiency, high cost, poor stability, and low production capacity. Therefore, the demand for improving the efficiency of the new generation of CNC grinding and polishing equipment is reflected; CNC grinding and polishing equipment is equipped with multiple sets of spindles, and cannot directly refer to the straight-row structure tool magazine of precision engraving machines and CNC equipment, so there is a demand for the use of special high-precision automatic tool changing devices for CNC grinding and polishing equipment.

[0006] Therefore, the present invention provides a tool magazine structure for CNC grinding and polishing equipment mainly used in the grinding and polishing industry, which can effectively solve the problems of complex tool changing structure, small tool magazine capacity, low tool setting accuracy, low efficiency of automatic tool changing, and easy manual errors in such previous equipment.
