Heat tube sucker for accelerating grinding heat transmission of thin-walled workpiece and method thereof

Abstract

The invention discloses a heat tube sucker for accelerating grinding heat transmission of a thin-walled workpiece and a method thereof. The heat tube sucker comprises a grinding electric permanent magnetic sucker, at least one heat tube and a heat radiation device which is connected with the heat tube, wherein the heat tube comprises a tube shell, a capillary liquid absorbing core and a working medium; the working medium has an effect of transmitting heat energy; the tube shell comprises an evaporation section, a heat insulating section and a condensing section, which are communicated with each other in an axial direction of the heat tube in sequence; the evaporation section of the heat tube is embedded at one part within the grinding electric permanent magnetic sucker close to a workpiece; a heat conductive silicon gel is arranged at an embedding clearance between the evaporation section and the grinding electric permanent magnetic sucker; the heat insulating section of the heat tube is fixedly connected with the grinding electric permanent magnetic sucker by a fixed auxiliary device; and the condensing section is arranged on the external side of the grinding electric permanent magnetic sucker and connected with the heat radiation device. The heat tube sucker for accelerating grinding heat transmission of the thin-walled workpiece, disclosed by the invention, has the following advantages that: by using the grinding electric permanent magnetic sucker provided with the heat tube, temperatures and heat expansions of the grinding electric permanent magnetic sucker and the workpiece are reduced; machining accuracy and surface quality of the workpiece are improved; and green grinding is achieved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a heat pipe suction cup and a method for accelerating heat transfer during grinding of thin-walled workpieces. Background technique [0002] In the existing processing technology, processing methods such as turning, grinding, planing, and milling are involved. Especially when grinding thin-walled workpieces, a large amount of grinding heat increases the temperature of the grinding area, which directly affects the wear and tear of the tool. The machining accuracy and surface quality of the workpiece. During grinding, more heat flows into the workpiece. The generation of grinding heat is inevitable. How to accelerate the dissipation of grinding heat and avoid overheating of the grinding area during the grinding process is an important issue to ensure the processing quality of the workpiece and the working life of the tool. [0003] In the traditional grinding process, the ...
