Abstract
Description
Technical Field
[0001] This utility model belongs to the field of axle heat treatment technology, and particularly relates to an adjustable axle heat treatment cooling air curtain device. Background Technology
[0002] In the heat treatment process of axles, the cooling process plays a crucial role in the performance of the axles, and the cooling air curtain device is a key piece of equipment for achieving efficient cooling.
[0003] Currently, the air outlet direction of traditional axle heat treatment cooling air curtain devices is mostly fixed. When heat treatment is required for axles of different specifications, fixed-direction air curtain devices often need to be disassembled, installed, or replaced, which is cumbersome, has poor adaptability, and cannot meet the efficient and flexible cooling requirements of modern axle production. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:
[0005] An adjustable axle heat treatment cooling air curtain device includes an air curtain machine. A connecting rod 1 and a mounting plate are hinged to the side of the air curtain machine away from the air outlet. A pin is fixedly connected to the end of the connecting rod 1 away from the air curtain machine. A connecting rod 2 is hinged to the side of the mounting plate near the air curtain machine. The end of the connecting rod 2 away from the mounting plate is rotatably sleeved on the outer ring of the pin. The pin is equipped with a positioning mechanism for limiting the angle between the connecting rod 1 and the connecting rod 2.
[0006] As a preferred embodiment of the above technical solution, the positioning mechanism includes a positioning plate movably sleeved on the outer ring of the pin, a guide slider fixedly connected to the inner wall of the positioning plate, a guide groove adapted to slide with the guide slider on the outer wall of the pin, and a plurality of positioning shafts that are inserted into the positioning plate fixedly connected to the side of the connecting rod two away from the connecting rod one.
[0007] As a preferred embodiment of the above technical solution, an anti-detachment baffle is fixedly connected to the end of the pin shaft away from the connecting rod, and the outer diameter of the anti-detachment baffle is larger than the inner diameter of the positioning plate.
[0008] As a preferred embodiment of the above technical solution, a reset spring is fixedly connected to one side of the positioning plate, and the end of the reset spring away from the positioning plate is fixedly connected to the anti-disengagement baffle.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. This utility model, through the hinged connection of connecting rod one and connecting rod two, the rotational connection of the pin shaft, and the angle fixing function of the positioning mechanism, can flexibly adjust the air outlet direction of the air curtain machine. Without disassembling or replacing the device, it can adapt to the cooling needs of axles of different diameters and lengths simply by adjusting the included angle between the two and fixing it with the positioning mechanism, greatly simplifying the operation process and improving production flexibility.
[0011] 2. This utility model, through the insertion and cooperation of the positioning plate and the positioning shaft, and the precise guidance of the guide slider and the guide groove, can stably limit the included angle between the first connecting rod and the second connecting rod. At the same time, the return spring continuously applies pressure to keep the positioning plate and the positioning shaft tightly fitted, and the anti-detachment baffle prevents the positioning mechanism from failing. This ensures that the direction of the air curtain remains stable after adjustment, guarantees uniform cooling of all parts of the axle, and improves the performance consistency of the axle after heat treatment.

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0017] Example
[0018] like Figure 1 and Figure 2 As shown, the adjustable axle heat treatment cooling air curtain device includes an air curtain machine 10. A connecting rod 11 and a mounting plate 20 are hinged to the side of the air curtain machine 10 away from the air outlet. A pin 30 is fixedly connected to the end of the connecting rod 11 away from the air curtain machine 10. A connecting rod 21 is hinged to the side of the mounting plate 20 near the air curtain machine 10. The end of the connecting rod 21 away from the mounting plate 20 is rotatably sleeved on the outer ring of the pin 30. The pin 30 is equipped with a positioning mechanism for limiting the angle between the connecting rod 11 and the connecting rod 21.
[0019] It should be noted that the air curtain machine 10, as a core component, is used to generate a cooling air curtain, which directly acts on the cooling process after the axle heat treatment. The "hinged" design of the air curtain machine 10 with the connecting rod 11 and the mounting plate 20, and the "rotatable sleeve" design of the connecting rod 21 and the pin 30, allow the air curtain machine 10 to rotate around the hinge point, providing mechanical movement possibilities for flexible adjustment of the air outlet direction. The positioning mechanism is used to fix the adjusted angle, preventing the air curtain machine 10 from shifting direction due to vibration and other factors during operation, and ensuring that the cooling air curtain acts stably on the target position.
[0020] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a positioning plate 32 movably sleeved on the outer ring of the pin 30. A guide slider 33 is fixedly connected to the inner wall of the positioning plate 32. A guide groove 31 is opened on the outer wall of the pin 30 to slide and adapt to the guide slider 33. Several positioning shafts 22 that are inserted into the positioning plate 32 are fixedly connected to the side of the connecting rod 21 away from the connecting rod 11.
[0021] Specifically, the "plug-in" cooperation between the positioning plate 32 and the positioning shaft 22: When the positioning plate 32 is plugged into the positioning shaft 22 at different positions, the relative rotation of the connecting rod 11 and the connecting rod 21 can be restricted, thereby fixing the tilt angle of the air curtain machine 10 and adapting to the cooling requirements of axles of different specifications; The "sliding fit" between the guide slider 33 and the guide groove 31: Restricts the positioning plate 32 to slide only along the axial direction of the pin shaft 30, avoiding misalignment between the positioning plate 32 and the positioning shaft 22 due to rotation, and ensuring positioning accuracy.
[0022] like Figure 2 As shown, an anti-detachment baffle 34 is fixedly connected to the end of the pin 30 away from the connecting rod 11. The outer diameter of the anti-detachment baffle 34 is larger than the inner diameter of the positioning plate 32.
[0023] Specifically, the anti-detachment baffle 34, with its outer diameter being larger than the inner diameter of the positioning plate 32, can effectively prevent the positioning plate 32 from falling off the pin 30, ensuring the structural integrity of the positioning mechanism, preventing device failure due to the positioning plate 32 falling off, and improving the reliability of the equipment.
[0024] like Figure 2 As shown, a return spring 35 is fixedly connected to one side of the positioning plate 32, and the end of the return spring 35 away from the positioning plate 32 is fixedly connected to the anti-detachment baffle 34.
[0025] Specifically, the elastic force of the return spring 35 always pushes the positioning plate 32 towards the connecting rod 21, achieving the following function:
[0026] When adjusting the angle, simply pull the positioning plate 32 to compress the return spring 35 to disengage it from the positioning shaft 22;
[0027] After adjustment, the reset spring 35 automatically resets, pushing the positioning plate 32 to reconnect with the corresponding positioning shaft 22. No manual fixing is required, simplifying the operation process.
[0028] Continuous elastic pressure can prevent the positioning plate 32 and the positioning shaft 22 from loosening due to vibration and other factors, further ensuring the stability of angle positioning.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
