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] Such as 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 i...

Abstract

The invention provides a device and method used for measuring end face turning temperature and belongs to the technical field of machining. The device and method are suitable for measuring temperature of a turning area during end face turning. The device comprises a thermocouple sensor, a slip ring and an experimental work piece which is specially designed, wherein the experimental work piece is a material product with turning temperature to be measured, annular ribs designed on the experimental work piece can convert end face turning into cylindrical turning, the thermocouple sensor can be reasonably buried in the work piece by designing a through hole and a blind hole, and safety of a turning process and signal stability are improved. Meanwhile, interference among devices is eliminated by the slip ring structure, temperature signals can be collected by a data collecting card through the slip ring and transmitted to a computer, and finally, more accurate end face turning temperature can be obtained. The device disclosed by the invention has a simple structure and is convenient to operate, and good measurement device and method can be used for achieving accurate measurement of end 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...
