Description

Heat-treated partition support device for lubrication-free sprocket production Technical Field

[0001] This utility model relates to the field of sprocket manufacturing technology, and in particular to a heat treatment separation support device for lubrication-free sprocket manufacturing. Background Technology

[0002] Lubrication-free sprockets are sprockets that can operate normally without the addition of lubricant during use. These sprockets typically use special materials and designs to reduce friction and wear, thus maintaining good operating conditions even without lubrication.

[0003] Lubrication-free sprockets have a graphite or ceramic coating on the surface of the metal sprocket. The metal base layer needs to be heat-treated during production. In the existing heat treatment process, the sprockets are stacked on top of each other, which can lead to uneven heating, easy bending, or even sticking together. Therefore, the sprockets need to be separated and supported during the heat treatment process to ensure the heating and heat treatment effect. Summary of the Invention

[0004] This utility model addresses the deficiencies in the prior art by providing a heat treatment separation support device for lubrication-free sprocket production.

[0005] This utility model is achieved through the following technical solution:

[0006] A heat treatment separation support device for lubrication-free sprocket production includes a base, a stock retaining ring, a support sleeve, a support mechanism, and a control rod. The stock retaining ring is fixedly installed on the top of the base, and the support sleeve is fixedly installed on the top of the stock retaining ring. The support mechanism is engaged inside the support sleeve, and the control rod is engaged inside the support sleeve. The support mechanism includes a telescopic rod, a pressure plate, a spring, a top rod, and a cover plate. An installation hole is provided on the outside of the support sleeve. The telescopic rod is engaged in the installation hole on the surface of the support sleeve. The pressure plate is fixed to the outside of the telescopic rod. The top rod is fixedly installed on the top of one end of the telescopic rod. The cover plate is sleeved on the outside of the telescopic rod, and the spring is disposed between the cover plate and the pressure plate.

[0007] In a preferred embodiment of this utility model, the control rod includes a contact end, a threaded end, and a pressing end. The threaded end is fixedly disposed at the bottom of the contact end, and the pressing end is disposed at the bottom of the threaded end.

[0008] In a preferred embodiment of this utility model, an inclined surface is provided on the outer side of the bottom of the extrusion end, an inclined surface is provided on the top of one end of the telescopic rod to cooperate with it, and an operating handle is fixedly provided on the top of the contact end.

[0009] The control rod is mainly used to control the extension and retraction of the support mechanism.

[0010] In a preferred embodiment of this utility model, the stocking ring has a threaded hole in the middle that mates with the threaded end, and a limit hole is provided at the bottom of the base.

[0011] The threaded hole in the middle of the circlip facilitates the fixing of the control rod, and the limiting hole at the bottom of the base facilitates the placement of the entire support device.

[0012] In a preferred embodiment of this utility model, the pressure plate is fixed to the inner side of the mounting hole on the outer side of the support sleeve, and one end of the spring is fixed to the inner side of the pressure plate;

[0013] When the control lever is inserted, the pressure plate compresses the spring, causing the telescopic rod to extend. When the control lever is pulled out, the telescopic rod automatically retracts under the action of the spring.

[0014] In a preferred embodiment of this utility model, the top rod has a conical structure.

[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0025] As shown in Figures 1-6, a heat treatment separation support device for lubrication-free sprocket production includes a base 1, a stock retaining ring 2, a support sleeve 3, a support mechanism 4, and a control rod 5. The stock retaining ring 2 is fixedly installed on the top of the base 1, the support sleeve 3 is fixedly installed on the top of the stock retaining ring 2, the support mechanism 4 is engaged inside the support sleeve 3, and the control rod 5 is engaged inside the support sleeve 3. The support mechanism 4 includes a telescopic rod 41, a pressure plate 42, a spring 43, a top rod 44, and a cover plate 45. The support sleeve 3 has an installation hole on its outside. The telescopic rod 41 is engaged in the installation hole on the surface of the support sleeve 3. The pressure plate 42 is fixed to the outside of the telescopic rod 41. The top rod 44 is fixedly installed on the top of one end of the telescopic rod 41. The cover plate 45 is sleeved on the outside of the telescopic rod 41, and the spring 43 is disposed between the cover plate 45 and the pressure plate 42.

[0026] Specifically, the control rod 5 includes a contact end 51, a threaded end 52, and a pressing end 53. The threaded end 52 is fixedly disposed at the bottom of the contact end 51, and the pressing end 53 is disposed at the bottom of the threaded end 52. An inclined surface is provided on the outer side of the bottom of the pressing end 53. An inclined surface that matches the top of one end of the telescopic rod 41 is provided. An operating handle is fixedly disposed on the top of the contact end 51. A threaded hole that matches the threaded end 52 is provided in the middle of the stock retaining ring 2. A limit retaining hole is provided at the bottom of the base 1. The pressure plate 42 is fixed to the inner side of the mounting hole on the outer side of the support sleeve 3. One end of the spring 43 is fixed to the inner side of the pressure plate 42. The top rod 44 has a conical structure.

[0027] In this embodiment, firstly, according to the number of support mechanisms 4 provided on the surface of the support sleeve 3, the sprocket that needs to be installed and supported is sleeved on the surface of the support sleeve 3 and slid down to the outside of the preparation retaining ring 2. Then, the uppermost sprocket is taken and moved to the top outside of the top support mechanism 4, and the control rod 5 is inserted into the top of the support sleeve 3. As the control rod 5 is inserted, the bottom slope of its bottom pressing end 53 will fit with the top slope of the telescopic rod 41. As the slopes press against each other, the telescopic rod 41 is pressed forward, causing the pressure plate 42 to compress the spring 43. After the telescopic rod 41 extends, the top rod 44 at one end can effectively support the bottom of the sprocket, thereby realizing the sprocket installation and support work.

[0028] Furthermore, following the above operations, the sprockets are supported and installed one by one. At this time, the contact end 51 of the control rod 5 will keep the telescopic rod 41 in the extended state. Then, the control rod 5 is rotated so that the threaded end 52 at its bottom connects with the threaded hole in the middle of the sprocket 2. At this time, the entire device can be lifted by the handle at the top of the control rod 5 for easy placement in the heating furnace. The limiting hole at the bottom of the base 1 facilitates installation and positioning. After heating is completed and cooling is achieved, the control rod 5 is directly rotated and pulled out. Under the action of the spring 43, the telescopic rod 41 automatically resets, causing the bottom of the sprocket to lose support and fall, making it easy to quickly remove all the sprockets. The cover plate 45 facilitates the installation of the support mechanism 4 on the surface of the support sleeve 3.
