[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) In the grinding wheel hardening furnace, when placing the grinding wheel, the furnace door is pulled out, and the movement trajectory of the furnace door is limited by the sliding plate and the sliding groove. When the furnace door is pulled out, the mounting plate is synchronously driven to move. After the mounting plate moves, the grinding wheel mounting column is brought out. At this time, the hole on the grinding wheel is aligned with the grinding wheel mounting column. Then, the grinding wheel is sleeved on the outer surface of the grinding wheel mounting column. When the grinding wheel moves, it contacts the limit plate. With the help of the inclined surface of the limit plate, the limit plate is squeezed to move toward the inside of the through groove and the spring is compressed. When the limit plate moves, the partition assembly is synchronously moved. After the partition assembly moves, it blocks the subsequent grinding wheel. At the same time, after releasing the hand, the spring is used to cooperate with the limit plate to complete the limiting fixation of the grinding wheel. Through the above structure, when fixing the grinding wheel, not only can the grinding wheel be directly slid in to complete the fixation, but also the synchronously moving partition assembly can be used to avoid the problem of multiple grinding wheels being close together and causing the heating efficiency to decrease.

[0015] (2) The grinding wheel hardening furnace uses a driving disk to cooperate with a worm to drive the worm wheel to rotate. After the worm wheel rotates, it simultaneously drives the two-way threaded rod to rotate. After the two-way threaded rod moves, it simultaneously drives the two locking plates to move in opposite directions, so that the locking plates enter the interior of the locking groove, thereby completing the fixation of the furnace door. Subsequently, the electric heating plate can be used for heating. When removing the grinding wheel, the furnace door is pulled out and the grinding wheel is directly controlled to move outward. When the grinding wheel is separated from the limit plate, the partition plate is retracted into the interior of the telescopic groove under the action of the second spring. Through the above structure, the grinding wheel can be disassembled more conveniently, thereby improving the overall loading and unloading efficiency of the grinding wheel, and the locking plate can be used to more conveniently complete the sealing of the furnace door to avoid internal heat loss.
