Description
Technical Field
[0001] This invention relates to the field of connection component technology, and more specifically to a connection component with shock absorption function. Background Technology
[0002] In the field of metal processing, many processing equipment generate significant vibrations during the processing process, such as stamping machines. These vibrations can easily cause damage to the equipment itself, such as loosening or misalignment of parts, and can also generate tremendous noise due to the impact with the ground. Therefore, for such equipment, vibration damping components are usually installed on the base of the equipment to reduce vibration.
[0003] Currently, the most common vibration damping components used for equipment such as stamping machines are rubber dampers. While this can provide some degree of vibration damping, the limited elasticity of rubber restricts its effectiveness. Furthermore, increasing the rubber thickness can negatively impact the installation stability of the stamping machine. Summary of the Invention

The flow rate of the first one-way valve is greater than that of the second one-way valve.

The third chamber is connected to the first chamber below the first piston through a second connecting pipe. One end of the first connecting pipe is connected to the second chamber, and the other end is connected to the third chamber. An electronic pressure gauge for monitoring the air pressure in the third chamber is installed on the side of the transition section.
[0010] A further technical solution is that the shock absorber also includes an air tube and a through-type lead screw motor. The air tube is vertically installed at the upper end of the buffer section, and the lower end of the air tube is connected to the second chamber. The inner wall of the air tube is provided with a support ring, a second spring, a sealing ring, and a second piston in sequence from bottom to top. The lower end of the second spring is in contact with the upper side of the support ring, and the upper side is connected to a sealing block that matches the center hole of the sealing ring.

The outer wall of the second piston is in a sealing sliding connection with the inner wall of the air tube. The second piston is provided with an air hole that passes through the upper and lower sides. A third one-way valve is installed in the air hole.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0021] Figures 1 to 4 The image shows an embodiment of the present invention.
[0022] Example:
[0023] A shock-absorbing connecting component includes an upper connecting part 1, a lower connecting part 2, and shock-absorbing rods 3. The lower side of the upper connecting part 1 has an upper mounting groove 4, and the upper side of the lower connecting part 2 has a lower mounting groove 5. The upper end of the lower connecting part 2 slides vertically within the upper mounting groove 4. The upper end of the shock-absorbing rod 3 is connected to the bottom of the upper mounting groove 4, and the lower end is connected to the bottom of the lower mounting groove 5. Two or more shock-absorbing rods 3 are provided. A rubber plate 6 is provided on the lower side of the lower connecting part 2. Using multiple shock-absorbing rods 3 in combination achieves a shock-absorbing effect, significantly improving the shock absorption performance. The connection method between the upper connecting part 1 and the lower connecting part 2 allows for relative sliding during shock absorption as the shock-absorbing rods 3 extend and shorten. The rubber plate 6 on the lower side of the lower connecting part 2 acts as a buffer between the connecting component and the ground, preventing noise caused by hard impacts. Figure 1 The diagram shows a connection component with shock absorption function installed at the bottom of the stamping machine 42 according to the present invention.
[0024] The shock absorber rod 3 includes an upper rod body 7, a lower rod body 8, and a first spring 9. The lower rod body 8 has a first chamber 10. The upper end of the lower rod body 8 has a sliding hole 11 that communicates with the first chamber 10. The lower end of the upper rod body 7 passes through the sliding hole 11 and is placed in the first chamber 10. A first piston 12 is connected in the first chamber 10. The outer wall of the first piston 12 slides and fits against the cavity wall of the first chamber 10. The outer wall of the lower rod body 8 has a lower top ring 13, and the outer wall of the upper rod body 7 has an upper top ring 14. The first spring 9 is sleeved on the outside of the upper rod body 7 and the lower rod body 8. The upper end of the first spring 9 is connected to the lower side of the upper top ring 14, and the lower end is connected to the upper side of the lower top ring 13. With this configuration, when the upper connecting part 1 is impacted, the upper connecting part 1 moves downward, causing the upper rod 7 to move downward. When the upper rod 7 moves downward, it compresses the space of the first spring 9 and the first chamber 10 located below the first piston 12. The impact force on the upper connecting part 1 is gradually mitigated by the elastic force of the first spring 9 and the resistance generated by the air compression in the space below the first piston 12, thus playing a buffering role.
[0025] The shock absorber 3 also includes a buffer section 15, within which a second chamber 16 is provided. The second chamber 16 is connected to the first chamber 10 below the first piston 12 via a first connecting pipe 17. The first connecting pipe 17 extends into the second chamber 16 and is sealed at its end. A first one-way valve 18 and a second one-way valve 19 are installed on the outer wall of the first connecting pipe 17 within the second chamber 16. The first one-way valve 18 allows unidirectional flow from the inside of the first connecting pipe 17 to the second chamber 16, and the second one-way valve 19 allows unidirectional flow from the second chamber 16 to the inside of the first connecting pipe 17. The flow rate of the first one-way valve 18 is greater than that of the second one-way valve 19. When the first piston 12 moves downward, it compresses the air below the first piston 12, which enters the second chamber 16 through the first connecting pipe 17 and then through the first one-way valve 18. After the upper connecting part 1 moves down a certain distance, and the impact force has been buffered by the first spring 9 and compressed air, the first spring 9 and the compressed air will push the upper rod 7 upward to reset. During the reset, the air that has entered the second chamber 16 will enter the first chamber 10 through the second one-way valve 19. Since the flow rate of the second one-way valve 19 is small, it will limit the upward movement speed of the upper rod 7 during the reset, thereby mitigating the upward impact force generated by the elastic potential energy of the first spring 9 on the upper rod 7. In this way, the shock absorber 3 can achieve excellent shock absorption effect throughout the entire shock absorption process.
[0026] The shock absorber 3 also includes a transition section 20, within which a third chamber 21 is provided. The third chamber 21 is connected to the first chamber 10 below the first piston 12 via a second connecting pipe 22. One end of the first connecting pipe 17 is connected to the second chamber 16, and the other end is connected to the third chamber 21. An electronic pressure gauge 23 for monitoring the air pressure in the third chamber 21 is installed on the side of the transition section 20. By providing the transition section 20, the upper rod 7 initially experiences impact, causing it to rapidly descend a certain distance and violently compress the air below the first piston 12. The third chamber 21 acts as a buffer space to mitigate this compression, preventing the air from overheating due to violent compression. The electronic pressure gauge 23 monitors the air pressure during the buffering process and during normal use. Since there are two or more shock-absorbing rods 3 between the upper connecting part 1 and the lower connecting part 2, if the air pressure in the third chamber 21 is different when the two shock-absorbing rods 3 are not subjected to impact, it means that the amount of air in the lower part of the first piston 12 is different. Therefore, when subjected to impact, the resistance generated by the compressed air in the lower part of the first piston 12 is different due to the different air pressure, resulting in different forces on each upper rod 7. This will cause the upper rod 7 subjected to the greatest force to fail prematurely. Therefore, after monitoring the different air pressures by the electronic pressure gauge 23, the air pressure can be adjusted to ensure that all shock-absorbing rods 3 are subjected to uniform force.
[0027] The shock absorber 3 also includes an air tube 24 and a through-type lead screw 31 motor 25. The air tube 24 is vertically installed at the upper end of the buffer part 15, and the lower end of the air tube 24 is connected to the second chamber 16. The inner wall of the air tube 24 is provided with a support ring 26, a second spring 27, a sealing ring 28 and a second piston 29 from bottom to top. The lower end of the second spring 27 is in contact with the upper side of the support ring 26, and the upper side is connected to a sealing block 30 that matches the center hole of the sealing ring 28. The through-type lead screw 31 motor 25 is installed at the upper end of the air tube 24. The lead screw 31 of the through-type lead screw 31 motor 25 passes into the air tube 24 and is connected to the second piston 29. The outer wall of the second piston 29 is in a sealing sliding connection with the inner wall of the air tube 24. The second piston 29 is provided with an air hole 32 that passes through the upper and lower sides. A third one-way valve is installed in the air hole 32. The third one-way valve is unidirectionally open from top to bottom. The through-type lead screw 31 and motor 25 can move the lead screw 31 up and down within the motor, thereby moving the second piston 29 up and down within the inflation tube 24. When the inflation tube 24 and the through-type lead screw 31 and motor 25 are not in use, the second spring 27 pushes the second piston 29 to contact and adhere to the sealing ring 28, keeping the second chamber 16 sealed and preventing gas leakage. When it is necessary to inflate the second chamber 16, the through-type lead screw 31 and motor 25 drive the lead screw 31 downward, and the second piston 29 compresses the air between the second piston 29 and the sealing ring 28. When the air pressure is greater than the elastic force of the second spring 27, it will drive the second spring 27 to compress, thereby allowing air to enter the second chamber 16 through the central hole of the sealing ring 28. When the through-type lead screw 31 and motor 25 drive the second piston 29 upward, the third one-way valve allows air to enter the lower side of the second piston 29, and at the same time, the second spring 27 pushes the sealing block 30 sealing post sealing ring 28 central hole. Inflation can be completed by repeatedly moving the second piston 29 up and down. Although the first piston 12, sliding hole 11, and other parts of this connecting assembly are sealed during use, some air leakage is inevitable after long-term use due to the moving connection parts. Therefore, by using the air tube 24 and the through-type lead screw 31 and motor 25, each shock absorber 3 can be quickly restored to the working air pressure without the need for the operator to open the connecting assembly for manual inflation.
[0028] The diameter of the central hole of the sealing ring 28 gradually decreases from bottom to top, and the shape of the sealing block 30 is set as a frustum to match the central hole of the sealing ring 28. The sidewall of the sealing block 30 is provided with a sealing layer. With this structure, the performance between the sealing block 30 and the sealing ring 28 can be improved.
[0029] An upper guide rod 33 is vertically installed at the bottom of the upper mounting groove 4, and a lower guide rod 34 is vertically installed at the bottom of the lower mounting groove 5. A guide hole 35 is provided at the upper end of the lower guide rod 34, and the lower end of the upper guide rod 33 slides vertically within the guide hole 35. By setting the upper guide rod and the lower guide rod 34, the vertical movement of the upper connecting part 1 and the lower connecting part 2 can be guided, preventing misalignment and damage to the shock absorber rod 3.
[0030] An upper connecting piece 36 is vertically installed at the bottom of the upper mounting groove 4, and an upper connecting rod 37 is horizontally arranged on the side of the upper connecting piece 36. A lower connecting piece 38 is vertically installed at the bottom of the lower mounting groove 5, and a lower connecting rod 39 is horizontally arranged on the side of the lower connecting piece 38. An upper connecting hole 40 and a lower connecting hole 41 are respectively provided at the upper and lower ends of the shock absorber rod 3. The upper connecting hole 40 is connected to the upper connecting rod 37, and the lower connecting hole 41 is connected to the lower connecting rod 39.
[0031] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims.
