Description

Technical Field

[0001] The utility model relates to the field of PCD tools, in particular to a PCD tool welding and tool changing device. Background Art

[0002] During the PCD tool replacement and grinding process, the used PCD sheet needs to be removed and the new PCD sheet needs to be welded into the original tool pit.

[0003] In the prior art, the key points of the PCD tool welding and changing process control need to be judged by visual observation. Since the welding area is small, the welding parts are covered with flux during welding, which obstructs the field of vision, and the welding temperature is judged by comparing the color changes of the welding parts when heated by the standard color card. For the above reasons, it is difficult to observe carefully with the naked eye, which may cause the weld to be too large or even the weld to fall off; it is also easy to cause inaccurate welding position, so that the tool has no processing allowance in subsequent processing; it is also easy to cause misjudgment of welding temperature. If the temperature is lower than the standard, it may cause the welding bond to be unreliable. If the temperature is higher than the standard, it may cause the PCD material to carbonize or crack, resulting in scrap. Utility Model Content
