Embodiment Construction

[0021] The structure and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] refer to figure 1 and figure 2 , a strain-type rotary two-component milling force sensor, including a main body structure 3 of the sensor, an interference fit between the coupling cover 2 and the central axis of the main structure 3, and threaded connections at the periphery, and screws between the front end structure 1 and the coupling cover 2 Through screw connection, the overall structure forms a dynamometer tool holder that can not only connect the spindle, install the tool, but also monitor the high-speed rotating milling force in real time.

[0023] see image 3 , the front end structure 1 is composed of a front HSK type tool holder head 1a and a rear disc 1b. The tool holder head 1a realizes the connection between the force sensor and the machine tool spindle, and has wide versatility. The rear disc 1b achieves...

Abstract

A strain type rotary two-component milling force sensor comprises a body structure. A binding cover is in interference fit with the central axis portion of the body structure, and is in threaded connection with the periphery of the body structure, and a front-end structure is in threaded connection with the binding cover. The front-end structure is formed by connecting a front HSK tool handle head and a rear disc, a force measuring sensor and a machine tool spindle are connected through the tool handle head, and the rear disc and the binding cover are in seamless connection. A thin-wall cylinder is arranged at one end of the body structure, a tool clamp is arranged at the other end of the body structure, a supporting disc is arranged in the middle of the body structure, the thin-wall cylinder is an elastic element of the whole sensor and is very high in sensitivity, and the overall structure rigidity and the sensitivity of the sensor are combined through the thin-wall cylinder. The supporting disc supports the modules of the sensor, and the tool clamp is used for mounting a tool. A metal strain sheet is pasted on the thin-wall cylinder, a Wheatstone full-bridge mode is formed in a connecting mode, and the sensor is used for measuring axial force Fz and spindle torque M, and has the advantages of being high in sensitivity, strong in anti-interference capacity, strong in universality and the like.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment manufacturing, in particular to a strain-type rotary two-component milling force sensor. Background technique [0002] High-speed cutting and high-speed machining have the advantages of high production efficiency, good machining accuracy, and long tool life. In recent years, they have occupied an indispensable position in modern precision and ultra-precision machining. In the process of high-speed cutting and high-speed machining, there is an obvious relationship between the magnitude of the cutting force on the tool and the change trend of the cutting force and the wear, damage and durability of the tool, which directly affects the processing quality. Therefore, it is particularly important to realize real-time monitoring of cutting force during machining. [0003] In order to monitor, analyze and control the cutting force of machine tools, different types of dynamometers have come...
