[0003] After searching, the patent number CN219326794U discloses a heat treatment device for high-temperature resistant bearing sleeves of automobile generators. The device is provided with a first clamping mechanism and a second clamping mechanism. After the bearing sleeve to be heat treated falls from the lower hopper into the discharge trough, the first clamping rod extends into the hollow ring in the middle of the bearing sleeve, and then the two clamping rods move outward to fix the bearing sleeve from the inside. Then, the first telescopic rod continues to move forward and extends into the protective cover, and is fixedly clamped to the surface of the bearing sleeve by the second clamping mechanism. Finally, the bearing sleeve can be quenched by a high-frequency quenching ring.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a heat treatment device for an automobile bearing.

[0025] The utility model provides Figure 1-3 The heat treatment device of an automobile bearing shown in the figure comprises a treatment chamber 1 and a mounting groove opened on the top of the treatment chamber 1, in which an arc-shaped quenching ring 2 is fixedly embedded, a feed hopper 3 is fixedly penetrated through the top of the treatment chamber 1, two symmetrically arranged rotating shafts 4 are rotatably penetrated through the back side of the treatment chamber 1, sprockets 5 are fixedly sleeved on the shaft walls of the two rotating shafts 4, a chain 6 is provided on the outer sides of the two sprockets 5 for common transmission, a plurality of vertical plates 7 arranged at intervals are fixedly provided on the outer sides of the chain 6, a plurality of cross bars 8 are rotatably penetrated inside the vertical plates 7, support rollers 9 are fixedly sleeved on the rod walls of the cross bars 8, a motor 10 is fixedly provided on the back side of the treatment chamber 1, and the output end of the motor 10 penetrates into the treatment chamber 1 and is fixedly connected to the rotating shaft 4.

[0026] Before heat treatment of the bearing, the arc quenching ring 2 is opened, and the bearing falls into the feed hopper 3, and enters between multiple support rollers 9 through the lower end channel of the feed hopper 3. Then the motor 10 is started, and under the transmission of the chain 6 and the sprocket 5, the multiple support rollers 9 drive the multiple bearings to move in the arc quenching ring 2, so that multiple bearings can be heat treated and heated at the same time.

[0027] In order to limit the bearing when it moves, Figure 1 and Figure 3 As shown, a bidirectional screw rod 13 is rotatably provided at the upper end of the inner wall of the processing chamber 1, and limit plates 14 are threadedly sleeved on both ends of the rod wall of the bidirectional screw rod 13. The bottom of the limit plate 14 is in contact and connected with the top of the inner wall of the processing chamber 1, and the end of the bidirectional screw rod 13 passes through the processing chamber 1 and is fixedly sleeved with a rotating block 15 for driving the bidirectional screw rod 13 to rotate. The two limit plates 14 are both L-shaped and covered on the outer lower end of the friction guide ring 11.

[0028] Before heat treatment of the bearing, observe the width of the bearing, then rotate the rotating block 15 to rotate the bidirectional screw 13. At this time, the bidirectional screw 13 drives the two limit plates 14 to move relative to each other, which can be wrapped around the outside of the bearing to stably limit the bearing during movement.

[0029] In order to allow the bearing to be fully heated while moving, the bearing should be kept away from the treatment chamber after heat treatment. Figure 1 As shown, a plurality of friction guide rings 11 are fixedly provided at intervals on the top of the inner wall of the arc-shaped quenching ring 2, and a discharge channel 12 is fixedly provided on the bottom of the inner wall of the processing chamber 1, and the inner wall of the discharge channel 12 is arranged in an arc shape.

[0030] During the movement of the bearing, the bearing contacts the friction guide ring 11, so that the bearing can rotate and can be fully heat treated. After processing, the bearing falls into the discharge channel 12 and rolls out of the processing bin 1 through the arc surface of the inner wall of the discharge channel 12.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
