Technical Field

[0001] This utility model relates to the field of nitriding furnace technology, specifically to an assembled hanging fixture for a nitriding furnace. Background Technology

[0002] A nitriding furnace is a piece of equipment used for nitriding metals. Nitriding is a surface hardening technology mainly applied to steel and other alloy materials. It involves introducing nitrogen gas onto the metal surface at high temperatures to form a nitrided layer, thereby improving the material's hardness, wear resistance, corrosion resistance, and fatigue strength. Nitriding is primarily used for components requiring high hardness and wear resistance, such as gears, bearings, and molds.

[0003] In traditional nitriding furnaces, hanging fixtures are mostly used to place the materials to be nitrided. Since the hanging fixtures are integrated with the nitriding furnace, the size of the hanging fixtures varies when placing different materials, which requires changing to different nitriding furnaces, which is inconvenient.

A top cover 4 is provided at the top of the electric push rod 3. An installation mechanism 5 is provided at the bottom of the top cover 4. A fixing rod 51 is fixedly connected to the bottom of the top cover 4. A collar 52 is slidably connected to the outer wall of the fixing rod 51.

[0022] The top of the collar 52 is provided with a storage groove 53, and the inner wall of the storage groove 53 is rotatably connected to a rotating shaft 54.

[0023] The storage slot 53 allows for the placement of the connecting arm 55, facilitating the placement of the overall collar 52.

[0024] The rotating shaft 54 ​​is fixedly connected to a connecting arm 55 at one end away from the inner wall of the storage groove 53, and the outer wall of the fixing rod 51 is provided with a threaded connecting groove 56.

[0025] By rotating the connecting arm 55, the through hole 57 can be aligned with the threaded connecting groove 56.

[0026] The outer wall of the connecting arm 55 has a through hole 57, and a fixing bolt 58 is provided inside the through hole 57. The fixing bolt 58 is threadedly connected to the threaded connection groove 56.

[0027] The connecting arm 55 and the fixing rod 51 can be connected by fixing bolt 58, which is threaded into the threaded groove 56.

[0028] The collar 52 has an adjustment mechanism 6 inside and a movable cavity 61 inside.

[0029] The adjustment mechanism 6 can adjust the orientation of the hook 66 to facilitate the placement of materials.

[0030] The inner wall of the movable cavity 61 is slidably connected to a movable plate 62, and a return spring 63 is fixedly connected to the top of the movable plate 62. The top of the return spring 63 is fixedly connected to the top of the inner wall of the movable cavity 61, and a hook 66 is rotatably connected to the bottom of the movable plate 62.

[0031] The movable plate 62 can drive the hook 66 to move vertically.

[0032] The bottom of the movable cavity 61 is provided with a first slot 64 and a second slot 65.
