DETAILED DESCRIPTION

[0023] The utility model will be further described in connection with the drawings:

[0024] Refer to the Figure 1 : a kind of rotary high-efficiency nitriding treatment device for mobile phone computer spare parts in the embodiment, including track piece 1, dial 2 and motor 3, annular track 11 is arranged on track piece 1, annular track 11 is used to place ring-shaped part 7, dial 2 is located above the track piece 1,

[0025] As shown in the accompanying Figure 4As shown, the outer edge of the dial 2 is circumferentially uniformly distributed with several horizontal mounting shafts 21, which are arranged above the annular track 11, and the horizontal mounting shafts 21 are used to mount the annular component 7;

[0026] The rotating shaft 31 of the motor 3 is circumferentially fixed and axially slidably connected with the center hole 22 of the dial 2, the upper side of the dial 2 is provided with a limiting ring 32, the limiting ring 32 is fixedly connected with the upper end of the rotating shaft 31, a return spring 33 is arranged between the limiting ring 32 and the dial 2, and the lower side of the dial 2 is provided with a lifting driving rod 4, which is used to drive the dial 2 to move up and down.

[0027] When the motor 3 drives the dial 2 to rotate, the horizontal mounting shaft 21 moves relative to the track 1, and the horizontal mounting shaft 21 drives the annular component 7 to move along the annular track 11.

[0028] Working principle: as shown in the accompanying Figure 2 The lower side of the dial 2 is provided with a lifting driving rod 4, and the height of the dial 2 can be adjusted through the lifting movement of the lifting driving rod 4, so as to adapt to different sizes of components. When the lifting driving rod 4 is elongated and the dial 2 is lifted up, the annular component 7 is mounted on the dial 2 through the horizontal mounting shaft 21. The horizontal mounting shaft 21 is circumferentially uniformly distributed, which can adapt to different sizes of annular components and ensure stable placement of the annular components on the dial 2. After the lifting driving rod 4 is shortened, the dial 2 moves downward under the action of the return spring 33, and the stable contact between the annular component and the annular track 11 is maintained. The rotating shaft 31 of the motor 3 is circumferentially fixed and axially slidably connected with the center hole 22 of the dial 2. This connection mode ensures that the dial 2 can drive the annular component 7 to move along the annular track 11 when rotating. When the motor 3 is started, the rotating shaft 31 drives the dial 2 to rotate, and the horizontal mounting shaft 21 of the dial 2 rotates to make the annular component 7 move along the annular track 11, so as to realize uniform nitriding of the surface of the component.

[0029] The track 1 is connected to the negative electrode of the power supply 5, which ensures that a stable electric field environment can be provided during the nitriding process. This enables the workpiece (annular component 7) to form a complete electric circuit with the power supply during ion nitriding, so as to realize the bombardment of nitrogen ions. As shown in the accompanying Figure 3As shown, the center hole 22 of the dial 2 is fixedly installed with an insulating sleeve 23, which electrically isolates the dial 2 from the rotating shaft 31 of the motor 3. This can prevent the dial 2 from transmitting electricity to the motor 3, avoiding the safety hazards caused by electrical short circuit or leakage, and protecting the motor from electrical field interference. The inner hole of the insulating sleeve 23 is fixedly provided with a key block 24, the rotating shaft 31 is installed in the insulating sleeve 23, the rotating shaft 31 is provided with an axial key groove 34, and the axial key groove 34 is in sliding connection with the key block 24. This design realizes the circumferential fixation (i.e. the rotating shaft can drive the dial to rotate) and axial sliding (i.e. the dial can move freely in the axial direction) between the rotating shaft 31 and the dial 2. When the motor 3 starts, the rotating shaft 31 transmits power to the dial 2 through the cooperation of the key block 24 and the axial key groove 34, so that the dial 2 can stably rotate. At the same time, due to the relative movement between the dial 2 and the track piece 1, the annular part 7 can move along the annular track 11, thereby realizing uniform nitriding.

[0030] Referring to the drawings Figures 1-2 The device further comprises a furnace body 6, which comprises an outer cover 61 and a base 62. The base 62 is connected to the positive electrode of the power supply 5, and forms an electrical circuit with the track piece 1 (connected to the negative electrode of the power supply 5). The outer cover 61 is the main shell part of the furnace body, which plays a protective and heat insulation role. The outer cover 61 is provided with a cavity 63 for accommodating the parts to be nitrided, such as the dial, the track piece 1 and the annular part 7. The cavity 63 is provided with an opening facing downward; the base 62 is located at the opening of the cavity 63 and is detachably connected to the outer cover 61 to close the cavity 63 and support the entire furnace body structure. The outer cover 61 and the base 62 are designed to be detachable, which facilitates the loading and unloading of the parts by the operator, and also facilitates the maintenance and cleaning of the interior of the furnace body.

[0031] The track piece 1 is fixedly installed on the connecting table 12 to ensure that the track piece 1 remains stable during nitriding. The connecting table 12 is provided with a support 13, which is fixedly connected to the furnace body 6 to provide additional support for the connecting table 12 and ensure the stability of the entire structure. The support 13 is provided with an electrically conductive part 14 in the inside, and the connecting table 12 is connected to the negative electrode of the power supply 5 through the electrically conductive part 14. The arrangement of the electrically conductive part 14 ensures that the electrical connection between the track piece 1 and the power supply 5 is stable and reliable, avoiding the problem of nitriding failure caused by circuit damage.

[0032] As shown in the drawings Figure 3 In order to facilitate the processing of spherical parts, a thrust bearing 15 is provided between the track piece 1 and the dial 2 to maintain a certain distance and reduce the friction between the track piece 1 and the dial 2. Limiting notches are provided between adjacent horizontal installation shafts 21 for placing spherical parts.

[0033] The upper end of the lifting driving rod 4 is provided with a roller 41, and the lower surface of the dial 2 is provided with an annular wheel groove 42 for rolling with the roller 41. The rolling contact of the roller 41 and the annular wheel groove 42 makes the lifting driving rod 4 be able to adjust the height of the dial 2 or the pressure between the annular part and the annular track in the nitriding process of rotation.

[0034] In order to improve the nitriding effect on the gear part, the annular track 11 is provided with an end face gear ring 16, and the tooth surface of the end face gear ring 16 is arranged upwards. The end face gear ring 16 can be engaged with the gear part, so as to improve the electrical contact and rotation effect.
