Technical Field

[0001] This utility model relates to a vertical shaft fixing bracket for an ion nitriding furnace, belonging to the technical field of machining auxiliary tools, specifically a vertical shaft fixing bracket for an ion nitriding furnace. Background Technology

[0002] Ion nitriding is a process that utilizes the glow discharge principle of plasma to introduce nitrogen ions into the workpiece surface. These ions combine with iron atoms to form an iron-nitrogen compound, creating a nitrided layer of a certain thickness. Due to its advantages such as minimal workpiece deformation, rapid nitriding speed, and controllable nitrided layer structure, ion nitriding technology has great application potential in the special motor industry.

[0003] A glow discharge ion nitriding furnace is a specialized device that uses a vacuum environment and pulsed power supply to achieve nitriding treatment of metal surfaces; it belongs to the category of chemical heat treatment furnaces. When processing motor shafts using an ion nitriding furnace, a protective coating needs to be applied to areas where nitriding is not permitted before exposing the shaft to the furnace with the maximum possible area. Therefore, the shafts cannot be stacked, necessitating an auxiliary tool that can fix and support the shafts inside the nitriding furnace. Utility Model Content

[0004] To address one of the aforementioned technical deficiencies, this utility model provides a vertical shaft fixing bracket for an ion nitriding furnace, which vertically fixes the shaft inside the nitriding furnace for processing, making it convenient and effective to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a vertical shaft fixing frame for an ion nitriding furnace, including a support platform, support columns and a clamping ring. The bottom surface of the support platform is provided with multiple support columns. The support platform is provided with a through hole for the vertical shaft to be processed to be placed through. The clamping ring is located directly above the through hole of the support platform and is fitted and clamped in the middle of the shaft body of the vertical shaft to be processed.

[0006] The clamping ring includes a ring body and a clamping bolt. Multiple clamping bolts are circumferentially arranged on the ring body by threads, and the bottom end of the stud of the clamping bolt points to the center of the ring body.

[0007] The outer diameter of the ring is greater than the diameter of the through hole, and the inner diameter of the clamping ring is greater than the diameter of the middle shaft of the vertical shaft to be processed.

[0008] The support column is a telescopic column structure.

[0009] The support column includes an outer tube and an inner support rod. The top end of the outer tube is fixedly connected to the bottom surface of the support platform. The upper part of the inner support rod is threaded into the inner cavity of the outer tube, and the bottom end of the inner support rod is provided with a polygonal prism head.

[0010] The support column includes a bottom sleeve, an adjusting inner rod, an adjusting handle, and a top sleeve. The bottom end of the bottom sleeve is fixed to the bottom surface of the nitriding furnace, and the top end of the top sleeve is fixedly connected to the bottom surface of the support platform. The bottom sleeve is threaded onto the lower part of the adjusting inner rod in a forward direction, and the top sleeve is threaded onto the upper part of the adjusting inner rod in a reverse direction.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model relates to a vertical shaft fixing bracket for an ion nitriding furnace, such as... Figure 1-2The diagram shows a vertical shaft 5 to be processed, including a support platform 1, support columns 2 and a clamping ring 3. The bottom surface of the support platform 1 is provided with multiple support columns 2. The support platform 1 is provided with a through hole 4 for the vertical shaft 5 to be processed to pass through. The clamping ring 3 is located directly above the through hole 4 of the support platform 1 and is fitted and clamped in the middle of the shaft body of the vertical shaft 5 to be processed.

[0022] like Figure 3-4 As shown, the clamping ring 3 includes a ring body 31 and a clamping bolt 32. Multiple clamping bolts 32 are circumferentially arranged on the ring body 31 by threads, and the bottom end of the stud of the clamping bolt 32 points to the center of the ring body 31.

[0023] In use, the vertical shaft 5 to be processed is hoisted above the corresponding through hole 4 of the support platform 1, the clamping ring 3 is fitted into the middle of the shaft body of the vertical shaft 5 to be processed, and the tightening bolt 32 is screwed so that the bottom end of the stud presses against the shaft surface of the vertical shaft 5 to be processed, so as to achieve multi-point contact clamping of the shaft body. Then the vertical shaft 5 to be processed is placed in the through hole 4 until the clamping ring 3 is pressed on the table surface of the support platform 1, thus realizing the placement of one vertical shaft 5 to be processed.

[0024] The outer diameter of the ring 31 is larger than the diameter of the through hole 4, so as to facilitate the clamping ring 3 on the support table 1. The inner diameter of the clamping ring 3 is larger than the diameter of the middle part of the vertical shaft 5 to be processed, so as to facilitate the clamping assembly of the ring 31 on the vertical shaft 5 to be processed.

[0025] The support column 2 is a telescopic column structure, which allows the height of the support platform 1 to be adjusted according to the length of the vertical shaft 5 to be processed.

[0026] like Figure 1 As shown, the support column 2 includes an outer tube 21 and an inner support rod 22. The top end of the outer tube 21 is fixedly connected to the bottom surface of the support platform 1. The upper part of the inner support rod 22 is threaded into the inner cavity of the outer tube 21. The bottom end of the inner support rod 22 is provided with a polygonal prism head 23. During adjustment, it is only necessary to slightly lift the bottom end of the inner support rod 22 and rotate the polygonal prism head 23 by operating a tool, thereby adjusting the total stroke of the outer tube 21 and the inner support rod 22, and thus adjusting the height of the support platform 1.

[0027] like Figure 5The diagram shows another structural schematic of the support column in this utility model. The support column 2 includes a bottom sleeve 24, an adjusting inner rod 25, an adjusting handle 26, and a top sleeve 27. The bottom end of the bottom sleeve 24 is fixed to the bottom surface of the nitriding furnace, and the top end of the top sleeve 27 is fixedly connected to the bottom surface of the support platform 1. The bottom sleeve 24 is threaded onto the lower part of the adjusting inner rod 25, and the top sleeve 27 is threaded onto the upper part of the adjusting inner rod 25. One end of the adjusting handle 26 is fixed to the middle of the adjusting inner rod 25. During adjustment, the adjusting handle 26 is rotated directly with a tool. Since the upper and lower threads of the adjusting inner rod 25 are in opposite directions, the total stroke of the bottom sleeve 24, the adjusting inner rod 25, and the top sleeve 27 can be adjusted when the adjusting handle 26 is rotated, thereby adjusting the height of the support platform 1.

[0028] There are 3-4 tightening bolts 32 on the clamping ring 3.

[0029] The support platform 1 is provided with multiple through holes 4 of different diameters to facilitate the placement of shafts of different diameters.

[0030] When processing ultra-long shafts, this invention allows for the stacking of 2-3 units to clamp and fix the ultra-long shaft, making its placement in the nitriding furnace more stable.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
