Problems solved by technology

However, for the measurement of turning temperature, due to the high-speed operation of the workpiece, it brings a lot of inconvenience to the temperature measurement, especially the end surface temperature measurement, there is a large centrifugal force, there is a certain signal interference, and the devices are easy to interfere with each other. The existing turning temperature measuring device has disadvantages such as complex structure and inaccurate measurement results

Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0019] like figure 1 As shown, the device includes a thermocouple sensor 5, a slip ring 9, a temperature signal processing terminal 16 and an experimental workpiece 1; the experimental workpiece 1 is a product of a turning temperature material to be measured, which is cylindrical, and a clamping space is reserved on the left side. The width of the turning tool is reserved on the right side, and the protruding annular rib 2 is in the middle. The number of annular ribs 2 on the experimental workpiece 1 is more than two, the height of the annular ribs 2 is 5-15mm, and the height gradually decreases from left to right; the thickness of the annular ribs 2 does not exceed the width of the blade 10, so that This outer circle turning process is equivalent to a 90° turning tool face turning process; the groove in t...

Abstract

The invention provides a device and method for measuring the temperature of end face turning, which belongs to the technical field of cutting processing and is suitable for measuring the temperature generated in the cutting area during end face turning. The device includes thermocouple sensors, slip rings and specially designed experimental workpieces. The experimental workpiece is the product of the turning temperature material to be tested. The annular rib designed on the experimental workpiece converts face turning into cylindrical turning. The design of the through hole and the blind hole makes the thermocouple sensor buried inside the workpiece reasonably, which improves the safety of the turning process and the stability of the signal. At the same time, the use of a slip ring structure eliminates interference between devices. The temperature signal is collected by the data acquisition card through the slip ring and transmitted to the computer, and finally a more accurate face turning temperature is obtained. The invention has simple structure and convenient operation, and provides a good measuring device and method for realizing accurate measurement of the face turning temperature.

Description

technical field [0001] The invention belongs to the technical field of cutting processing, and relates to a measuring device and a measuring method for an end face turning temperature. Background technique [0002] Turning temperature is an important physical phenomenon produced in the turning process. Part of the heat generated during the turning process is dissipated in the surrounding medium, and the rest is transferred to the tool, chip and workpiece to obtain a certain temperature. Different turning temperatures will lead to thermal deformation of different tools and workpieces, which will affect the machining accuracy of parts, tool life and reduce production efficiency. At the same time, since the structure of metal materials will also change with the turning temperature, the turning temperature is also an important factor affecting the surface quality of the workpiece. Therefore, the further development of the turning process can be promoted by studying the turning...
