[0001] The invention relates to the technical field of metal processing equipment, and more specifically to a high-frequency electromagnetic heating CNC tool handle thermal expansion processing device. Background Art

[0002] In recent years, with the rapid development of CNC machine tool technology, CNC toolholders, as key connecting components between machine tools and tools, have a direct impact on machining efficiency and workpiece surface quality due to their machining accuracy and assembly quality. Traditional CNC toolholder thermal expansion processing mostly uses resistance heating or flame heating to achieve interference fit between the toolholder and the tool through thermal expansion. However, the existing technology has the following significant problems:

[0003] Traditional resistance heating relies on contact heat transfer, which has the problem of uneven heating temperature distribution, which can easily cause local overheating or insufficient heating of the tool handle, affecting assembly accuracy; flame heating has the problems of difficult temperature control, high energy consumption and safety hazards.

[0004] Based on the above problems, we provide a high-frequency electromagnetic heating CNC tool holder thermal expansion processing device. Summary of the invention

[0035] Specifically, the electric push rod 1 202 and the electric push rod 2 401 are both servo electric push rods, which are controlled by the PLC controller program.

[0036] Specifically, the placing rack 402 is driven to move to the top of the processing table 1 by the electric push rod 2 401, and then the tool handle to be processed is inserted on the placing rack 402, and then the electric push rod 1 202 drives the heating element 3 to move down to cover the tool handle, and the tool handle is heat-processed.
