Description

Technical Field

[0001] The utility model belongs to the technical field of ion nitriding, and in particular relates to an ion nitriding tool for spherical parts. Background Art

[0002] For the ion nitriding treatment of spherical parts, especially the steel balls in rolling bearings, the treated steel balls are required to have uniform nitriding layer and consistent surface quality. However, if the spherical parts are fixed during the ion nitriding process, contact marks will appear at the parts in contact with the tooling. Not only will the color difference affect the appearance quality, but the nitriding layer at the contact part is thinner than that at other parts, and the hardness is lower. In order to solve this problem, two methods are generally used at home and abroad: one is to put the spherical parts into the furnace for nitriding for a period of time and then stop, cool to room temperature, take out, turn it over, and then put it into the furnace to continue nitriding treatment. Each nitriding treatment must be repeated several times to complete, the production efficiency is low, and the nitriding quality is difficult to achieve the best. Another method is to support the spherical parts with three pointed thin rods to minimize the contact area between the support and the sphere. Even so, it is inevitable to leave traces of support on the sphere.

[0003] Therefore, it is of great significance to design an ion nitriding tooling that can eliminate the contact marks between spherical parts and the tooling during the ion nitriding process. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] As attached Figure 1-Figure 3As shown, in an illustrative embodiment of the ion nitriding tooling of a spherical component of the utility model, the ion nitriding tooling of the spherical component includes a track member 5, a dial 3 and a motor 6; the track member 5 is limited to form an annular track; the annular track is arranged in a horizontal direction, and the annular track is used to place the spherical component 4; the dial 3 is located above the track member 5, and a limiting notch is provided at the outer edge of the dial 3, and the limiting notch is arranged corresponding to the annular track, and at least a part of the spherical component 4 placed on the annular track is arranged in the limiting notch, so that the dial 3 drives the spherical component 4 to move along the annular track; the rotating shaft 61 of the motor 6 is connected to the dial 3.

[0041] When the motor 6 drives the dial 3 to rotate, the dial 3 and the track member 5 move relative to each other, and the dial 3 drives the spherical component 4 to move along the circular track.

[0042] The above-mentioned ion nitriding tooling for spherical parts sets a circular track to make the spherical part 4 move along the circular track, so that the ion beam evenly bombards the surface of the part, eliminates the traces of contact with the tooling, realizes uniform nitriding of the spherical part 4, and improves the nitriding quality; by setting a dial 3 and setting a limiting notch on the dial 3, at least part of the spherical part 4 is set in the limiting notch, so that the dial 3 drives the spherical part 4 to move along the circular track, ensuring the reliability of the movement of the spherical part 4 along the circular track; by setting a motor 6 to drive the dial 3 to rotate, the dial 3 drives the spherical part 4 to move along the circular track.

[0043] During the ion nitriding process, the track member 5 is connected to the negative pole of the power source 7 and the spherical component 4 is placed in the circular track. Therefore, the spherical component 4 and the dial 3 in contact with the spherical component 4 are charged due to indirect connection with the negative pole of the power source 7.

[0044] In order to prevent the dial 3 from transmitting the electrical properties of the track member 5 to the motor 6 and causing safety hazards, such as Figure 2 As shown, the rotating shaft 61 of the motor 6 is connected with an insulating member 8 , and the rotating shaft 61 of the motor 6 is connected to the dial 3 through the insulating member 8 .

[0045] like Figure 3 As shown, the rotating shaft 61 is provided with a stopper, the rotating shaft 61 is connected with a fastener 9, the middle part of the insulating member 8 is provided with a connection hole for the rotating shaft 61 to pass through, one side of the insulating member 8 abuts against the stopper, and the other side of the insulating member 8 abuts against the fastener 9, and the fastener 9 and the stopper cooperate with each other to fix the insulating member 8 and the rotating shaft 61.

The reserved gap is provided to block the cathode glow and prevent arc discharge from being generated at the reserved gap when the spherical component 4 is ion nitrided.

[0049] In some embodiments, the vertical distance t of the reserved gap is 0.5-0.9 mm, and the horizontal depth h of the reserved gap is greater than 10 mm.

[0050] like Figure 2 and Figure 3 As shown, the insulating member 8 includes a first insulating member 81 and a second insulating member 82, and the first insulating member 81 is arranged above the second insulating member 82; at least a portion of the first insulating member 81 and / or at least a portion of the second insulating member 82 is arranged in the avoidance space or through the avoidance hole, so that the first insulating member 81 and the second insulating member 82 are connected to each other; the first insulating member 81 and the second insulating member 82 jointly define a card slot.

[0051] In some embodiments, the first insulating member 81 and the second insulating member 82 are respectively made of ceramic.

[0052] A step is provided at the outer edge of the first insulating member 81 facing the second insulating member 82 , and the step is arranged upward in a direction close to the slot opening, so that the first insulating member 81 and the upper surface of the dial 3 define a reserved gap together.

[0053] A step is provided at the outer edge of the second insulating member 82 facing the first insulating member 81 , and the step is arranged downward in a direction close to the slot opening, so that the second insulating member 82 and the upper surface of the dial 3 define a reserved gap together.

[0054] It should be noted that reserved gaps are respectively provided on the upper and lower sides of the dial 3 .

[0055] A first positioning portion is provided on the side of the first insulating member 81 facing the second insulating member 82, and a second positioning portion is provided on the side of the second insulating member 82 facing the first insulating member 81.

[0058] like Figure 1 As shown, when the spherical component 4 is subjected to ion nitriding, the above-mentioned spherical component ion nitriding tooling is arranged in the furnace body 1; the furnace body 1 includes an outer cover 11 and a base 12, the outer cover 11 defines a cavity 110, and the cavity 110 is provided with an opening arranged downward; the base 12 is located at the opening of the cavity 110 and is detachably connected to the outer cover 11 to close the cavity 110, wherein the base 12 is connected to the positive pole of the power supply 7.

[0059] like Figure 1 As shown, a connection platform 2 is provided in the cavity 110 , and the connection platform 2 is used to place the track member 5 ; the connection platform 2 is connected to the negative pole of the power source 7 , so that the negative pole of the power source 7 is indirectly connected to the track member 5 .

[0060] It should be noted that, due to the different outer dimensions of the spherical components 4 , the dimensions of the annular track for placing the spherical components 4 are also different. Therefore, by replacing the track member 5 , ion nitriding of the spherical components 4 with different outer dimensions can be achieved.

[0061] The connecting platform 2 is provided with a supporting member 21 , and the track member 5 is detachably provided on the top of the supporting member 21 .

[0062] In some embodiments, a plurality of support members 21 are provided, and the plurality of support members 21 are arranged along the annular track to increase the supporting effect of the support members 21 on the track member 5 .

[0063] A through opening is provided in the middle portion of the connecting platform 2 for the rotating shaft 61 to pass through. When the rotating shaft 61 is arranged upward, the rotating shaft 61 passes through the through opening and the avoidance hole in sequence to be connected with the insulating member 8 .

[0064] like Figure 1 As shown, a mounting member 13 is disposed on the base 12 , and the mounting member 13 is used to place the connecting platform 2 so that the connecting platform 2 is disposed in the cavity 110 .

[0065] The base 12 is provided with threading holes, which extend in the vertical direction and are connected to the cavity 110.

[0066] In some embodiments, the threading holes are located at the outer edge of the base 12 .

[0067] The base 12 is further provided with an insertion opening, which extends in a vertical direction and is communicated with the cavity 110 , so that the rotating shaft 61 of the motor 6 passes through the insertion opening and is disposed in the cavity 110 .

[0068] In some embodiments, the access opening is located in a middle portion of the base 12 .

[0069] like Figure 2 As shown, the motor 6 includes a motor body and a rotating shaft 61 . The motor body is disposed outside the cavity 110 . One end of the rotating shaft 61 is connected to the motor body, and the other end of the rotating shaft 61 passes through the insertion port and extends into the cavity 110 to be connected to the dial 3 .

[0070] In some embodiments, an opening is provided on the bottom surface of the annular track, the opening is vertically penetrated through the track member 5, and the opening extends along the annular track so that the ion beam can pass through the opening and contact the spherical component 4. It should be noted that the size of the opening is smaller than the diameter of the spherical component 4 to prevent the spherical component 4 from falling from the opening.

[0071] The working principle of the above-mentioned ion nitriding tooling for spherical components is as follows: the spherical component 4 is placed in the circular track and at least part of the spherical component 4 is arranged in the limiting notch, the motor 6 drives the dial 3 to rotate, and the dial 3 drives the spherical component 4 to move along the circular track so that the ion beam evenly bombards the surface of the component.

[0074] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
