Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0018] like Figure 1-3 As shown:

[0019] The present embodiment provides a quenching furnace for bearing processing, comprising a first workbench 100, a second workbench 200, and a quenching device 300 arranged between the first workbench 100 and the second workbench 200, wherein a first linear drive slide 101 is fixedly provided on the upper part of the first workbench 100, a mounting shaft seat 102 is provided on the first linear drive slide 101, a screw sleeve 103 is fixedly provided on one side of the first workbench 100 corresponding to the mounting shaft seat 102, and the screw sleeve 103 and the mounting shaft seat 102 are connected to each other. 02, a rotating screw 104 is provided between them, one end of the rotating screw 104 is rotatably set in the mounting shaft seat 102, and the other end is set through the screw sleeve 103, and the end is provided with a first bearing sleeve 105, a second linear drive slide 210 is fixedly provided on the upper part of the second workbench 200, the second linear drive slide 210 is provided with a support 220 which moves with it, a rotating shaft 230 is provided on the support 220 corresponding to the rotating screw 104, and a second bearing sleeve 240 is provided at the end of the rotating shaft 230.

[0020] When in use, the second linear slide drives the support 220 to move close to one end of the high-frequency quenched copper tube 302, that is, the rotating shaft 230 is set through the high-frequency quenched copper tube 302, and one end of the bearing to be processed is fixed by the second bearing sleeve 240, and the first linear drive is controlled to move, so that the first bearing sleeve 105 is clamped with the other end of the bearing, and then the first linear drive and the second linear drive are controlled to move synchronously, that is, when the first linear drive moves, the rotating screw 104 is fixed because the screw sleeve 103 is fixed, so it can rotate while moving linearly. After the workpiece completely passes through the high-frequency heating copper tube, the quenching treatment of the workpiece is completed, and the trough body of the reflux groove 304 is tilted, so that the coolant enters the equipment body 301 through the reflux groove 304 for recycling.

[0021] like Figure 3 As shown, the quenching equipment 300 includes an equipment body 301 disposed between the first workbench 100 and the second workbench 200 , a high-frequency quenching copper tube 302 and a cooling spray pipe 303 are disposed on one side of the equipment body 301 , and a reflux tank 304 is disposed at the lower part thereof.

[0022] like Figure 1 , 3 As shown, the high-frequency quenching copper tube 302 and the cooling spray tube 303 are both arranged close to one side of the second workbench 200 , and the cooling spray copper tube is arranged closer to the second workbench 200 .

[0023] like Figure 2 , 3 As shown, the rotating screw 104, the rotating shaft 230, the high-frequency quenching copper tube 302 and the cooling spray tube 303 are all coaxially arranged.

[0024] like Figure 1 , 2As shown, a controller 400 is fixedly provided on one side of the first workbench 100, and the controller 400 is electrically connected to the first linear drive slide 101, the second linear drive slide 210 and the equipment body 301 respectively, and then controlled by the controller 400, when the bearing is clamped and assembled, the second linear slide is stationary, and the first linear slide moves toward the second linear slide, and further the first bearing sleeve 105 and the second bearing sleeve 240 clamp and fix the bearing;

[0025] When the bearing is quenched, the controller 400 controls the first linear slide and the second linear slide to move synchronously. At this time, due to the screw shaft sleeve fixedly arranged on the first workbench 100, the first linear slide pushes the rotating screw 104 to rotate when moving, so that the bearing workpiece to be processed rotates with it, and then cooperates with the high-frequency quenching copper tube 302 to perform quenching work;

[0026] When removing the workpiece, the controller 400 controls the first linear slide to retreat first and then controls the second linear slide to retreat, so that the bearing workpiece can be removed smoothly.

[0027] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
