Description

Technical Field

[0001] This application relates to the field of shock absorbers, and in particular to a high-temperature resistant shock absorber structure. Background Technology

[0002] Shock absorbers, as key components for suppressing rebound oscillations after spring-absorbing shocks and buffering impacts from various sources, play a crucial role in the field of robotics. When a robot performs a task, its joints and body are prone to vibration during movement, and shock absorbers can quickly attenuate these vibrations. This not only significantly improves the accuracy and smoothness of the robot's movements but also greatly optimizes the robot's operational performance.

[0003] In complex external environments, dust in the air can penetrate anywhere. If dust enters the interior of the shock absorber and adheres to the piston rod, it will accelerate wear during frequent extension and contraction, greatly reducing the service life of the shock absorber.

[0004] In existing technologies, to prevent dust from entering the shock absorber, a telescopic dust cover is installed on the piston rod of the shock absorber. These telescopic dust covers are mostly made of rubber or plastic and are folded, allowing them to extend or compress during shock absorber movement. However, the folded portion of the telescopic dust cover easily accumulates dust, making cleaning difficult. Furthermore, frequent extension and retraction can lead to fatigue damage at the fold, thus affecting the dust-proof effect. Utility Model Content

[0005] To address the problem that installing a telescopic dust cover on the piston rod for dust prevention is problematic because the folded part easily accumulates dust, making cleaning difficult, and frequent extension and retraction can lead to fatigue damage at the folded part, thus affecting the dust prevention effect, this application provides a high-temperature resistant shock absorber structure.

[0006] The high-temperature resistant shock absorber structure provided in this application adopts the following technical solution:

[0007] A high-temperature resistant shock absorber structure includes a first disc and a second disc. A first connecting assembly is fixed to the side of the first disc facing away from the second disc, and a second connecting assembly is fixed to the side of the second disc facing away from the first disc. A limiting sleeve is coaxially fixed on the first disc, with the diameter of the end of the limiting sleeve near the first disc being smaller than the diameter of its other end. A first outer cylinder is welded to the side wall of the first disc, and a stop is fitted on the limiting sleeve. A fixing rod is coaxially fixed on the second disc, and multiple disc springs are coaxially fitted on the fixing rod. A second outer cylinder is welded to the side wall of the second disc and is disposed between the first outer cylinder and the limiting sleeve. An oil layer is provided between the first outer cylinder and the second outer cylinder. Multiple fixing mechanisms that restrict the movement of the stop are evenly arranged inside the first outer cylinder.

[0008] By adopting the above technical solution, the oil layer set between the first outer cylinder and the second outer cylinder can effectively improve the sealing performance and reduce friction. At the same time, the oil layer can also prevent external dust from entering the internal structure through the gap between the first outer cylinder and the second outer cylinder. In addition, the first disc and the first outer cylinder are fixed by welding, which makes the two seamlessly connected and effectively prevents external dust from entering the internal structure. This solves the problem in the prior art that the folded part of the telescopic dust cover is prone to dust accumulation, making cleaning difficult, and frequent extension and retraction can lead to fatigue damage at the fold, thus affecting the dustproof effect. Therefore, it ensures the normal operation of the shock absorber in complex environments and improves the service life of the shock absorber.

[0009] Optionally, the fixing mechanism includes a fastening bolt, a receiving groove one formed on the stop, and a receiving groove two formed on the second outer cylinder and used in conjunction with the receiving groove one. The stop and the second outer cylinder are connected by the fastening bolt.

[0010] By adopting the above technical solution, the stop and the second outer cylinder are connected by fastening bolts, which is simple to operate and can be quickly assembled. Furthermore, with the cooperation of receiving groove one and receiving groove two, the fastening bolts can be accurately positioned, enhancing the connection stability and preventing component displacement.

[0011] Optionally, the first connecting component includes a connecting plate fixed on the first disk, and the connecting plate has connecting holes.

[0012] By adopting the above technical solution, the connection holes opened on the connecting plate provide connection points for the shock absorber to be installed on the robot. The connection holes provide multiple connection methods, which greatly improves the flexibility and convenience of installation.

[0013] Optionally, the second connecting assembly includes two symmetrically fixed receiving plates on the second disk, each receiving plate having a receiving hole.

[0014] By adopting the above technical solution, two symmetrically fixed receiving plates to the second disk construct a stable and evenly stressed connection structure. The receiving holes on the receiving plates provide various connection methods, enhancing versatility and adaptability.

[0015] Optionally, the disc spring is a high-temperature resistant alloy spring.

[0016] By adopting the above technical solution and using high-temperature resistant alloy springs to manufacture disc springs, the performance of disc springs in high-temperature environments can be significantly improved. In high-temperature environments, the disc springs can stably maintain their elasticity, ensuring the normal operation of the shock absorber.

[0017] Optionally, the inner walls of the first outer cylinder, the second outer cylinder, and the limiting sleeve are all provided with a lubricating coating.

[0018] By adopting the above technical solution, a lubricating coating is applied to the inner walls of the first outer cylinder, the second outer cylinder, and the connecting sleeve, which reduces component wear and extends their service life. Simultaneously, it also helps improve the smoothness of the shock absorber's operation and reduces energy loss.

[0019] Optionally, the side of the first disc away from the limiting sleeve is connected to an oil inlet, and an oil cap is threaded onto the oil inlet.

[0020] By adopting the above technical solution, lubricating oil can be easily injected into the oil filler port, fully lubricating the key parts of the shock absorber, reducing component friction and wear, and extending the service life of the equipment. The threaded connection of the oil cap effectively prevents dust and impurities from entering the oil filler port, and also facilitates daily inspection and opening operations.

[0021] Optionally, the first disc has an oil injection channel inside, and the oil injection port is connected to the oil injection channel.

[0022] By adopting the above technical solution, operators can accurately deliver lubricating oil to the internal parts that need lubrication through the oil inlet and oil channel, effectively reducing friction between components, reducing wear, and extending the service life of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first disc and the first outer cylinder are fixed together by welding, forming a seamless connection that further prevents external dust from entering. In addition, the oil layer set between the first and second outer cylinders not only reduces frictional loss but also prevents dust from entering through the gap between the first and second outer cylinders, thereby preventing dust from entering the shock absorber and ensuring stable operation of the shock absorber in complex environments;

[0025] 2. The design of the oil inlet, oil cap, and oil channel facilitates the injection of lubricating oil into the internal lubrication points, reducing component friction and wear, and extending the service life of the equipment. At the same time, the oil cap can block dust and impurities, making daily inspection and opening operations convenient. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a high-temperature resistant shock absorber structure.

[0036] Example 1:

[0037] Reference Figure 1 A high-temperature resistant shock absorber structure includes a first disk 1 and a second disk 2. Both disks are made of high-temperature alloy material, enabling them to maintain structural strength and stability under high-temperature conditions. A first connecting component 3 is fixed to the first disk 1. The first connecting component 3 includes a connecting plate 301 and a connecting hole 302. The connecting plate 301 is fixedly connected to the first disk 1, and the connecting hole 302 is formed on the connecting plate 301. The connecting plate 301 is made of high-temperature alloy material, enabling it to maintain structural strength and stability under high-temperature conditions.

[0038] A second connecting component 4 is fixed on the side of the second disk 2 away from the first disk 1. The second connecting component 4 includes two receiving plates 401. Each of the two receiving plates 401 has a receiving hole 402. Both receiving plates 401 are made of high-temperature alloy material, which can maintain structural strength and stability in high-temperature environments.

[0039] By setting a first connecting component 3 at one end of the shock absorber and a second connecting component 4 at the other end, the shock absorber can be installed on the robot under the combined action of the first connecting component 3 and the second connecting component 4, thereby providing buffering and shock absorption for the operation of the robot.

[0040] Reference Figure 2 A limiting sleeve 5 is coaxially fixed on the side of the first disk 1 near the second disk 2. A stop 7 is coaxially fitted on the limiting sleeve 5, and the inner diameter of the stop 7 is the same as the outer diameter of the upper part of the limiting sleeve 5 near the first disk 1. In addition, both the limiting sleeve 5 and the stop 7 are made of high-temperature alloy material, which can maintain structural strength and stability in high-temperature environments.

[0041] A first outer cylinder 6 is welded to the side wall of the first disk 1. A fixing rod 8 is coaxially fixed to the side of the second disk 2 near the first disk 1, and multiple disc springs 9 are sleeved on the fixing rod 8. The disc springs 9 are high-temperature resistant springs made of nickel-chromium alloy. In high-temperature environments, the disc springs 9 can stably maintain their elasticity, ensuring the normal operation of the shock absorber. A second outer cylinder 10 is welded to the outer wall of the second disk 2, located between the first outer cylinder 6 and the limiting sleeve 5. The first outer cylinder 6, the fixing rod 8, and the second outer cylinder 10 are all made of high-temperature alloy material, enabling them to maintain structural strength and stability in high-temperature environments.

[0042] Reference Figure 2 The first disc 1 and the first outer cylinder 6 are fixed by welding, so that the two are seamlessly connected, effectively preventing external dust from entering the internal structure of the shock absorber. In addition, an oil layer 11 is provided between the first outer cylinder 6 and the second outer cylinder 10. The oil layer 11 is filled with grease, which can reduce friction. At the same time, the oil layer 11 can also prevent external dust from entering the internal structure through the gap between the first outer cylinder 6 and the second outer cylinder 10, ensuring the stable operation of the shock absorber in complex environments.

[0043] Reference Figure 2 In order to further restrict the movement of the stop 7, multiple fixing mechanisms 12 are evenly arranged inside the first outer cylinder 6. The stop 7 and the second outer cylinder 10 are fixed by the fixing mechanisms 12, thereby restricting the movement direction of the second outer cylinder 10 by the stop 7.

[0044] Reference Figure 3The limiting sleeve 5 consists of two parts, an upper part and a lower part. The outer diameter of the upper part, which is closer to the first disc 1, is smaller than that of the lower part. The inner diameter of the limiting sleeve 5 is the same as the diameter of the fixing rod 8, allowing the fixing rod 8 to slide within the limiting sleeve 5 during shock absorber operation. Furthermore, under the action of the fixing mechanism 12, the limiting sleeve 5 can also compress the multiple disc springs 9 sleeved on the fixing rod 8, thus buffering the pressure.

[0045] Reference Figure 4 The fixing mechanism 12 includes a fastening bolt 1201, a receiving groove 1202, and a receiving groove 1203. The receiving groove 1202 is formed on the stop 7, and the receiving groove 1203 is formed on the second outer cylinder 10. The receiving groove 1202 and the receiving groove 1203 are matched to receive the fastening bolt 1201. The stop 7 and the second outer cylinder 10 are connected by the fastening bolt 1201.

[0046] The stop 7 and the second outer cylinder 10 are connected by fastening bolts 1201, which is simple to operate and can be quickly assembled. With the cooperation of receiving groove one 1202 and receiving groove two 1203, the fastening bolts 1201 can be accurately positioned, enhancing the connection stability and preventing component displacement.

[0047] In Embodiment 1 of this application, the implementation principle of a high-temperature resistant shock absorber structure is as follows: a telescopic dust cover is installed on the piston rod of the shock absorber for dust prevention. However, the folded part is prone to dust accumulation and is difficult to clean, and frequent extension and retraction can cause fatigue damage at the fold, affecting the dust prevention effect. To address the above problems, the side wall of the first disc 1 is welded to the first outer cylinder 6 to ensure a seamless connection between the two, effectively preventing external dust from entering the interior. In addition, an oil layer 11 filled with grease is provided between the first outer cylinder 6 and the second outer cylinder 10, which greatly reduces the friction between the components. At the same time, the oil layer 11 serves as an additional protection, further preventing dust from entering the gap between the first outer cylinder 6 and the second outer cylinder 10, thereby preventing dust from entering the interior of the shock absorber and ensuring the stable operation of the shock absorber. Furthermore, the first disc 1, the second disc 2, the connecting plate 301, the receiving plate 401, the limiting sleeve 5, the first outer cylinder 6, the stop 7, the fixing rod 8, the disc spring 9, and the second outer cylinder 10 are all made of high-temperature resistant materials, enabling the shock absorber to operate normally even in high-temperature environments.

[0048] Example 2:

[0049] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 5 An oil inlet 13 is connected to the side of the first disc 1 away from the limiting sleeve 5, and an oil cap 14 is threaded onto the oil inlet 13. Both the oil inlet 13 and the oil cap 14 are made of high-temperature alloy material, which can maintain structural strength and stability in high-temperature environments. Lubricating oil can be easily injected into the inside of the shock absorber through the oil inlet 13 to fully lubricate the inside of the shock absorber.

[0050] Furthermore, when the oil cap 14 and the oil inlet 13 are tightly screwed together, it can effectively prevent dust, impurities, and other foreign objects from entering the oil inlet 13, thus avoiding contamination of the lubricating oil or damage to the internal parts of the equipment. In addition, during routine equipment maintenance, operators can easily open the oil cap 14 by simply rotating it, making the operation very convenient.

[0051] Reference Figure 6 An oil injection channel 15 is provided inside the first disc 1, and the oil injection port 13 is connected to the oil injection channel 15. When the operator performs lubrication maintenance on the shock absorber, the lubricating oil can be easily delivered to the inside of the shock absorber through the oil injection port 13 and the oil injection channel 15 to lubricate the internal parts, thereby ensuring that the shock absorber functions stably, improving the accuracy and smoothness of the robot's movements, and optimizing the robot's operating performance.
