Problems solved by technology

At present, the chains used in most domestic chain tool magazines are imported, and the quality of domestic chains is relatively poor.
During the long-term operation of the chain tool magazine, due to the influence of various factors, the chain will wear out and the distance between the chain links will change, which will cause the meshing between the chain and the sprocket to change, directly affecting the machine tool The accuracy and reliability of automatic tool change may seriously cause failures such as tool drop and collision

Abstract

The invention discloses a device and method for testing chain pitch changes in a chain type tool magazine, and belongs to the field of performance detection of functional parts of a numerical control machine tool. Magnetic railing ruler reading heads are mounted through a guide rail and supporting plates which are specially designed; two Zigbee modules are utilized as data collectors; TTL signals generated by the two magnetic railing ruler reading heads are collected, and data are transmitted out in a wireless transmission manner; and one Zigbee module is adopted as a receiver, and the Zigbee module and a PC are in data interaction at a receiving end in a serial port communication manner. VC++6.0 is used for compiling upper computer software, and the data are stored, analyzed, processed and displayed on the PC. By means of the device and method for testing the chain pitch changes in the chain type tool magazine, the problem that the chain pitch changes of the chain type tool magazine are hard to detect is solved, the basis can be provided for abrasion of chains of the chain type tool magazine and other studies, and some experimental data are provided for chain manufacturers.

Description

technical field [0001] The invention relates to a device and method for testing the change of the chain pitch in a chain tool magazine, which belongs to the field of performance testing of functional components of numerical control machine tools. Background technique [0002] The automatic tool changing device of the CNC machining center consists of a tool magazine for storing tools and a tool changing mechanism. There are many types of tool magazines, and the common ones are disc tool magazines, bamboo hat magazines, chain tool magazines, etc. The chain tool magazine has the advantages of a large number of stored tools, a simple mechanism, and easy maintenance, and is mostly used in medium and large CNC machine tools. At present, the chains used in most domestic chain tool magazines are imported, and the quality of domestic chains is relatively poor. During the long-term operation of the chain tool magazine, due to the influence of various factors, the chain will wear out...
