[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0022] Embodiment 1, refer to Figures 1 to 5The utility model provides a kind of automobile gearbox gear carburizing quenching equipment, including box 1, box 1 is used to place gear and carbon block, in turn box 1 enters heat treatment furnace, gear and carbon can be heated to carry out carburizing quenching treatment work, box 1 is equipped with frame 2, frame 2 is connected with bucket 3, bucket 3 is used to put carbon block, bucket 3 is rotatably connected with sleeve 4, sleeve 4 is slidably connected with shaft 5, shaft 5 can be lifted and moved in sleeve 4, sleeve 4 is rotatably connected with screw 6, screw 6 is rotatably connected with shaft 5, one end of shaft 5 is equipped with conical block 8, bucket 3 is connected with conical ring 9, the lifting and moving of shaft 5 is driven by screw 6, the distance between conical block 8 and conical ring 9 can be adjusted, so that carbon block can be crushed to different degrees when passing between conical block 8 and conical ring 9, and fall into box 1, so that the fine fragmentation of appropriate carbon block can increase the contact area of carbon block and gear. When the degree of fragmentation of carbon block is appropriate, the carbon element can diffuse to the gear surface more quickly in the same carburizing time, and the carburizing speed is increased. This is particularly important for mass production of carburizing quenched gears, which can effectively shorten the production cycle and improve production efficiency.

[0023] In the embodiment, a plurality of hole bodies 11 are formed at one end and the other end of the box 1, and a plurality of column bodies 10 are inserted into the plurality of hole bodies 11. The connection between the column body 10 and the hole body 11 allows the box 1 and the frame 2 to be quickly disassembled and assembled. The plurality of column bodies 10 are connected to the frame 2. A motor 12 is installed at the frame 2. The model of the motor 12 is selected according to actual working requirements. The output end of the motor 12 is connected to the sleeve 4. A plurality of grooved wheels 13 are driven by a belt 14. The conical block 8 is connected to the shaft 5 by a bolt. A handle 7 is connected to the screw 6. The handle 7 is used to drive the screw 6 to rotate. The bucket 3 is designed to be conical in some areas. The conical ring 9 is designed to be conical at one end and the other end. The carbon block in the bucket 3 can be crushed by sliding through the conical design at one end of the conical ring 9 and falling between the conical design at the other end of the conical ring 9 and the conical block 8.

[0024] The working principle of the embodiment is as follows: during use, the handle 7 drives the shaft 5 to move up and down according to the quenching requirements of the actual gear. The shaft 5 drives the conical block 8 and the conical ring 9 to adjust the distance between them. When the carbon block in the bucket 3 is continuously put in, the carbon block can be finely crushed to different degrees when passing through the conical block 8 and the conical ring 9 with different distances. The crushed carbon block falls into the box 1 and accumulates. After the carbon block is processed, the frame 2 is separated from the box 1. The gear is placed in the carbon pile in the box 1. Since the carbon block is crushed, it can contact the gear. The box 1 is placed in the heat treatment furnace. The gear can be carburized and quenched with sufficient contact with carbon to achieve high quality.
