Description

Technical Field

[0001] This utility model relates to an eccentric shaft carbonitriding treatment device. Background Technology

[0002] Eccentric shafts require carbonitriding surface treatment during manufacturing to achieve corrosion resistance, impact resistance, and resistance to deformation. In existing technologies, traditional carbonitriding furnace equipment typically uses a swing-type furnace cover at the furnace inlet. This means that the opening and closing of the furnace inlet is controlled by swinging the furnace cover, resulting in poor sealing performance and easy spillage of raw materials. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and to provide an eccentric shaft carbonitriding treatment device with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The eccentric shaft carbonitriding treatment equipment includes a base, a furnace body, a furnace liner, and a furnace cover. The furnace body is fixed on the base, the furnace liner is disposed inside the furnace body, and the furnace cover is disposed above the furnace body. Its structural features are: it also includes a moving frame, a moving motor, a moving lead screw, a rotating motor, a rotating gear, meshing teeth, and a cylinder. The moving frame is slidably disposed on the base. The cylinder barrel is disposed on the top of the moving frame. The piston rod of the cylinder is connected to the furnace cover. The motor shaft of the moving motor is connected to the moving lead screw. The moving lead screw passes through the moving frame and the two are threadedly connected. The motor shaft of the rotating motor is connected to the rotating gear. The outer wall of the furnace liner is provided with meshing teeth, and the meshing teeth mesh with the rotating gear.

[0005] Furthermore, the movable frame is provided with a slider, the base is provided with a groove, and the slider is located in the groove.

[0006] Furthermore, a ball bearing seat is provided at the bottom outside the furnace shell, and a ball bearing groove is provided at the bottom inside the furnace body. Ball bearings are installed in the ball bearing seat and are located in the ball bearing groove.

[0007] Furthermore, the furnace cover is provided with a conduit that communicates with the furnace chamber.

[0008] Compared with the prior art, the present invention has the following advantages: the eccentric shaft carbonitriding treatment equipment can move the furnace cover to the top of the furnace body by moving the moving frame back and forth. When the furnace cover is located at the top of the furnace body, the furnace cover can be moved down by the cylinder to cover the furnace body tightly, thereby improving its sealing performance and preventing raw materials from scattering.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0014] Example

[0015] See Figures 1 to 3 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0016] The eccentric shaft carbonitriding treatment equipment in this embodiment includes a base 1, a furnace body 2, a furnace liner 3, a furnace cover 4, a moving frame 5, a moving motor 8, a moving lead screw 9, a rotating motor 10, a rotating gear 11, a meshing gear 12, and a cylinder 13. The furnace body 2 is fixed on the base 1, the furnace liner 3 is disposed inside the furnace body 2, the furnace cover 4 is disposed above the furnace body 2, the moving frame 5 is slidably disposed on the base 1, a slider 6 is disposed on the moving frame 5, a sliding groove 7 is disposed on the base 1, and the slider 6 is located in the sliding groove 7.

[0017] In this embodiment, the cylinder barrel of cylinder 13 is located on the top of the movable frame 5. The piston rod of cylinder 13 is connected to the furnace cover 4. The motor shaft of movable motor 8 is connected to movable lead screw 9. Movable lead screw 9 passes through movable frame 5 and the two are threaded together. The motor shaft of rotating motor 10 is connected to rotating gear 11. The outer wall of furnace liner 3 is provided with meshing teeth 12, which mesh with rotating gear 11.

[0018] In this embodiment, a ball bearing seat 15 is provided at the bottom outside the furnace chamber 3, a ball bearing groove 16 is provided at the bottom inside the furnace body 2, a ball bearing 14 is installed in the ball bearing seat 15 and the ball bearing 14 is located in the ball bearing groove 16, and a conduit 17 communicating with the furnace chamber 3 is provided on the furnace cover 4.

[0019] Specifically, when the eccentric shaft needs to be carburized, the cylinder 13 pulls the furnace cover 4 upward, the moving motor 8 drives the moving screw 9 to rotate, and the moving screw 9 controls the moving frame 5 to move, so that the furnace cover 4 is separated from the furnace body 2. The raw material is put into the furnace chamber 3 and the furnace chamber 3 is preheated (the preheating process is existing technology). When the appropriate temperature is reached, the eccentric shaft is placed in the furnace body 2. The moving motor 8 drives the moving screw 9 to rotate, and the moving screw 9 controls the moving frame 5 to move. When the furnace cover 4 is above the furnace body 2, the cylinder 13 pushes the furnace cover 4 downward to cover the furnace body 2. The rotating motor 10 drives the rotating gear 11 to rotate. Since the rotating gear 11 meshes with the meshing gear 12, the furnace chamber 3 can rotate. The furnace chamber 3 is designed to rotate more smoothly and avoid friction between the furnace chamber 3 and the furnace body 2. The exhaust gas generated in the furnace chamber 3 can be discharged through the conduit 17.

[0020] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
