[0022] Refer to Figure 1 and Figure 2The utility model is a fast feeding device for bearing tempering processing. The main structure includes a fixed frame arranged on one side of the tempering conveyor frame 1. The tempering conveyor frame 1 is used to convey the tempering box 2 containing the bearing to the tempering furnace. The tempering conveyor frame 1 is rotatably connected to a plurality of conveying rollers 3 for conveying the tempering box 2 through bearings. The plurality of conveying rollers 3 are driven to rotate simultaneously by the same motor through a synchronous belt, or each conveying roller 3 is driven to rotate by a single motor. A plurality of conveying rollers 4 are welded or bolted to the conveying roller 3. The tempering box 2 is placed on the tempering conveyor frame 1. When the tempering box 2 is on the frame 1, the bottom of the tempering box 2 contacts with a plurality of conveying rollers 4, and the conveying rollers 3 are used to drive the conveying rollers 4 to rotate, thereby pushing the tempering box 2 to move toward the tempering furnace. Preferably, the conveying rollers 3 and the conveying rollers 4 are also arranged in the tempering furnace, which is convenient for the movement and transportation of the tempering box 2 during and after the tempering process. A lifting plate 5 is vertically slidably connected to the fixed frame. When the lifting plate 5 is located at a low position, the tempering box 2 containing the bearing is placed on the lifting plate 5. The two sides of the fixed frame are symmetrically slidably connected to the moving frame 6, and the fixed frame is provided with a power to drive the moving frame 6 to slide horizontally. Rod 7, when the lifting plate 5 drives the tempering box 2 to rise, the mobile frames 6 on both sides move in opposite directions to leave space for the lifting of the lifting plate 5. After the lifting plate 5 drives the tempering box 2 to rise to a height higher than the tempering conveying frame 1, the mobile frames 6 on both sides slide relatively to the bottom of the tempering box 2, and the mobile frames 6 are rotatably connected to a plurality of loading rollers 8 through bearings. The loading rollers 8 are driven to rotate by a motor, and a plurality of loading rollers 9 corresponding to the positions of the conveying rollers 4 are welded or bolted on the loading rollers 8. The mobile frames 6 on both sides slide relatively until the loading rollers 9 are aligned with the conveying rollers 4. The rear lifting plate 5 drives the tempering box 2 to descend so that the bottom of the tempering box 2 contacts the feeding rollers 9 on the movable frames 6 on both sides. In this way, when the feeding rollers 8 drive the feeding rollers 9 to rotate, the tempering box 2 is pushed toward the tempering conveying frame 1. After the tempering box 2 moves to the tempering conveying frame 1, the conveying rollers 3 are used to drive the conveying rollers 4 to rotate, and the tempering box 2 is conveyed to the tempering furnace, so that the tempering box 2 can be quickly loaded. The loading is faster, and the tempering box 2 will not shake or tilt during the loading process, which reduces the possibility of the bearing falling off, thereby improving the efficiency and safety of the loading operation. Figure 4 The bottom of the tempering box 2 is provided with a limiting groove 10 used in conjunction with the conveying roller 4 and the loading roller 9. With this structure, when the loading roller 9 or the conveying roller 4 contacts the bottom of the tempering box 2, both are located in the limiting groove 10, thereby effectively limiting the position of the tempering box 2 during the loading process, avoiding the movement, dislocation or shaking of the tempering box 2, and further improving the safety and stability of loading.

[0023] Preferably, the fixing frame includes a vertical column 11 and a side frame 12. Both the vertical column 11 and the bottom of the side are fixed to the ground by anchor bolts or concrete pouring. The lifting plate 5 is slidably connected to the vertical column 11 in the vertical direction. The setting of the vertical column 11 can provide support for the up and down lifting of the lifting plate 5. A power assembly for driving the lifting plate 5 to slide up and down is provided on the vertical column 11. The power assembly makes the up and down movement of the lifting plate 5 more stable and labor-saving. The side frames 12 are symmetrically welded or bolted to both sides of the vertical column 11. The moving frame 6 is slidably connected to the side frames 12 in the horizontal direction. The side frames 12 provide support for the horizontal sliding of the moving frame 6, so that the overall structure of the fixing frame provides stable support for both the lifting and lowering of the lifting plate 5 and the horizontal sliding of the moving frame 6, improving the overall firmness of the feeding structure.

[0024] Preferably, referring to Figure 3 , the power assembly includes a power groove 13 provided on the vertical column 11. The power groove 13 penetrates the front side of the vertical column 11. The lifting plate 5 passes through the position penetrated by the front side and is slidably connected to the power groove 13. The setting of the power groove 13 can provide guidance for the up and down sliding of the lifting plate 5. A screw rod 14 is rotatably connected to the power groove 13 through a bearing. The screw rod 14 penetrates the lifting plate 5 and is threadedly connected thereto. The screw rod 14 is driven to rotate by a motor. Such a structure only needs to drive the screw rod 14 to rotate by the motor to drive the lifting plate 5 to move up and down under the action of the threaded connection, making the up and down lifting of the lifting plate 5 drive the tempering box 2 more stable and accurate.

[0025] Preferably, a reinforcing rod 15 is welded or bolted to the bottom of the lifting plate 5. The bottom end of the reinforcing rod 15 is slidably connected to the side wall of the power groove 13. Specifically, a sliding groove is provided at the bottom of the reinforcing rod 15, and the sliding groove is slidably connected to the side wall of the power groove 13. The reinforcing rod 15 is used to provide sufficient support for the suspended end of the lifting plate 5, further improving the firmness of the tempering box 2 on the lifting plate 5.

[0026] Preferably, a horizontal guiding column 16 is welded or bolted to the side frame 12. A supporting rod 17 is welded or bolted to the bottom of the moving frame 6. The end of the supporting rod 17 is slidably connected to the guiding column 16. Specifically, a sliding ring is provided at the end of the supporting rod 17, and the sliding ring is slidably sleeved on the outer side of the guiding column 16. Such a structure uses the supporting rod 17 to provide support for the suspended end of the moving frame 6, so that the sliding ring at the end of the supporting rod 17 slides on the guiding column 16 when the moving frame 6 slides, making the sliding structure of the moving frame 6 more firm and further ensuring the stability of the tempering box 2 feeding from the moving frame 6 to the tempering conveyor rack 1.

[0027] Preferably, referring to Figure 5, two thread regions with opposite helix directions are provided on the power rod 7. Sliders 18 are welded or bolted to both sides of the moving frame 6. The two thread regions penetrate through the sliders 18 on both sides and are threadedly connected thereto. With such a structure, when the power rod 7 rotates, the two sliders 18 and the moving frame 6 can be simultaneously driven to slide relatively or away from each other under the action of the two thread regions with opposite helix directions, thereby simultaneously realizing the synchronous sliding control of the moving frames 6 on both sides, simplifying the complexity of the device, and further improving the feeding efficiency.

[0028] Working principle: The structure of the present utility model is provided with a fixed frame on one side of the tempering conveyor frame 1. A lifting plate 5 is slidably arranged vertically on the fixed frame. The tempering box 2 containing bearings is placed on the lifting plate 5. The tempering box 2 is lifted to a height higher than that of the tempering conveyor frame 1 by using the lifting plate 5. Then, the moving frames 6 on both sides are slid horizontally relative to each other, so that the feeding rollers 9 on the moving frames 6 are aligned with the conveying rollers 4 on the tempering conveyor frame 1. Then, the tempering box 2 is lowered to the same height as the tempering conveyor frame 1 by using the lifting plate 5. At this time, the bottom of the tempering box 2 is in contact with the feeding rollers 9 on both sides at the same time. Then, the rotation of the feeding roller 8 on the moving frame 6 is used to drive the feeding roller 9 to rotate, so that the tempering box 2 moves onto the tempering conveyor frame 1. The bottom of the tempering box 2 is in contact with the conveying roller 4. The conveying roller 3 is used to drive the conveying roller 4 to rotate, and the tempering box 2 is conveyed into the tempering furnace for heating and heat preservation, so that the tempering box 2 containing bearings can perform a rapid feeding operation, the operation is more convenient, the risk that the bearings may fall out due to the inclination of the tempering box 2 is reduced, and the efficiency and safety of the feeding operation are improved; a limiting groove 10 for cooperating with the conveying roller 4 and the feeding roller 9 is provided at the bottom of the tempering box 2. With such a structure, when the feeding roller 9 drives the tempering box 2 to move towards the tempering conveyor frame 1 and the conveying roller 4 drives the tempering box 2 to move towards the tempering furnace, both the feeding roller 9 and the conveying roller 4 rotate in the limiting groove 10 at the bottom of the tempering box 2, effectively restricting the position of the tempering box 2, avoiding the inclination or shaking of the tempering box 2, and further improving the stability and safety of feeding.
