Embodiment Construction

[0026] The invention is a device for long-term continuous monitoring of broach movement in broaching. It transmits motion information based on the principle of radio frequency identification. By installing the monitoring device on the broach and the machine tool, the tool life cycle Long-term continuous monitoring of broach movement; specifically, the passive anti-metal tag embedded in the handle of the broach is used as a data storage chip, and then the anti-metal tag is read and written through the ultra-high frequency reader installed inside the machine tool Operation, to achieve long-term continuous broach motion information collection. The whole set of device can automatically identify the label and write specific data through the embedded program design, without the support of the host, it can be directly installed inside the machine tool, and can ensure long-term, continuous and accurate broach movement monitoring.

[0027] Below in conjunction with embodiment and accom...

Abstract

Provided is an on-line monitoring device and a method for the motion state of a broach. The on-line monitoring device comprises an RFID anti-metal tag, a reader-writer and a support assembly of a motion monitoring device. The RFID anti-metal tag is mounted to a broach handle. The reader-writer is fixed onto a machine tool by means of the support assembly of the motion monitoring device and capable of adjusting the direction thereof within the certain angle range in order to ensure normal communication between reader-writer and the RFID anti-metal tag. The reader-writer transmits an electromagnetic wave signal with frequency band ranging from 901 to 928 MHZ. When the RFID anti-metal tag enters the region of a magnetic field with the broach, the RFID anti-metal tag receives the electromagnetic wave signal ad obtains energy for sending the electromagnetic wave signal from the interior. The reader-writer receives interior information sent out by the RFID anti-metal tag and writes in information on broaching frequency of the broach to the RFID anti-metal tag such that on-line and active accurate monitoring of the broaching frequency of the broach is achieved. The on-line monitoring device and method for the motion state of the broach has following beneficial effects: real-time and on-line monitoring of the total number of machined workpieces during the whole service lifetime of the broach is realized; characteristics such as non-contact and long recording duration are obtained; and the on-line monitoring device and method are suitable for broaches with different kinds of specifications.

Description

technical field [0001] The invention relates to an on-line monitoring device and method for the motion state of a broach, in particular to a device and a method for monitoring the motion state of a broach by using radio frequency identification (RFID) technology, and belongs to the technical field of mechanical cutting processing. Background technique [0002] Broaching is a type of mechanical processing, which is a cutting process that uses broaches of various shapes to process various internal and external forming surfaces. Compared with other cutting processes, broaching has the following characteristics: high production efficiency, high machining accuracy, easy operation, and wide processing range, but the tool structure is complicated and the cost is high. [0003] The structure and shape of broaching tools are very complex. According to the working conditions, they should have high strength, toughness and wear resistance. The materials are mainly coated high-speed stee...
