Insulation device and method for tool cutting temperature measurement experiment

Abstract

The invention belongs to the technical field of tool detection, and discloses an insulation device and method for a tool cutting temperature measurement experiment. The insulating device comprises an insulating frame which is used for accommodating a cutter and is provided with an opening; the insulating frame comprises two vertical side plates which are connected with each other, a bottom plate which is connected with the two vertical side plates, and a movable cover plate which is movably connected with the two vertical side plates; a plurality of sawtooth structures are arranged on the bottom plate; the vertical side plates conduct lateral insulation positioning on the two side surfaces, not connected with the cutting edge, of the cutter, the bottom plate conducts insulation positioning on the bottom of the cutter, and the movable cover plate conducts insulation positioning on the top of the cutter. The insulation device and method can effectively avoid the problem of inaccurate cutting temperature experiment data of the cutter caused by the fact that the detection head of the contact type temperature measuring device is not insulated, and the insulation device is simple in structure, low in manufacturing difficulty, low in cost, good in heat conduction performance and reliable in insulation. The method is particularly suitable for a cutting temperature measurement experiment of a mesoscopic morphology coating tool for machining difficult-to-machine metal.

Description

technical field [0001] The invention belongs to the technical field of tool detection, and relates to an insulation device and method used in a tool cutting temperature measurement experiment. Background technique [0002] The commonly used temperature measuring devices in the tool cutting temperature measurement experiment are divided into contact type and non-contact type. In the cutting temperature measurement experiment of mesomorphic coating tools, in order to make the experimental data as close as possible to the actual temperature, the temperature measuring device used is generally a contact thermometer. Contact temperature measuring devices include expansion thermometers, pressure gauge thermometers, thermocouples, and thermal resistances. Expansion thermometers and pressure gauge thermometers cannot be used in experiments due to objective reasons such as fragility or excessive volume, so they can only be used Two kinds of thermometers, thermocouple and thermal resi...
