[0002] In the field of metal processing, many processing equipment will generate great vibrations during the processing, such as stamping machines. These vibrations not only easily cause some damage to the equipment itself, such as loose and misaligned parts, but also cause huge noise due to the impact with the ground. Therefore, for this type of equipment, some shock-absorbing components are generally installed on the base of the equipment to reduce vibration.

[0003] At present, for equipment such as stamping machine tools, the most commonly used shock-absorbing component is rubber shock absorption. Although this can achieve a certain degree of shock absorption effect, the shock absorption effect is limited due to the elastic range limitation of the rubber itself.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Figures 1 to 4 An embodiment of the present invention is shown.

[0021] Example: A connection component with a shock-absorbing function includes an upper connection part 1, a lower connection part 2 and a shock-absorbing rod 3. An upper mounting groove 4 is provided on the lower side of the upper connection part 1, a lower mounting groove 5 is provided on the upper side of the lower connection part 2, the upper end of the lower connection part 2 is slidably arranged in 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, and more than two shock-absorbing rods 3 are provided; a rubber plate 6 is provided on the lower side of the lower connection part 2. The shock-absorbing effect can be greatly improved by combining multiple shock-absorbing rods 3. The connection between the upper connection part 1 and the lower connection part 2 can slide relative to each other in coordination with the extension and contraction of the shock-absorbing rod 3 during shock absorption. The rubber plate 6 is provided on the lower side of the lower connection part 2, which can serve as a buffer between the connection component and the ground to avoid noise caused by hard collisions, such as Figure 1 It is a schematic diagram showing a connection assembly with a shock absorbing function according to the present invention installed on the bottom of a punching machine 42 .

[0022] The shock-absorbing rod 3 includes an upper rod body 7, a lower rod body 8 and a first spring 9. A first chamber 10 is arranged in the lower rod body 8. A sliding hole 11 connected to the first chamber 10 is arranged at the upper end of the lower rod body 8. The lower end of the upper rod body 7 is placed in the first chamber 10 through the sliding hole 11, and a first piston 12 is connected in the first chamber 10. The outer wall of the first piston 12 slides and fits with the cavity wall of the first chamber 10 up and down; a lower top ring 13 is arranged on the outer wall of the lower rod body 8, and an upper top ring 14 is arranged on the outer wall of the upper rod body 7. The first spring 9 is sleeved on the outer side of the upper rod body 7 and the lower rod body 8, and 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 such an arrangement, when the upper connecting part 1 is impacted, the upper connecting part 1 moves downward, driving the upper rod body 7 to move downward. When the upper rod body 7 moves downward, the first spring 9 and the space of the first chamber 10 below the first piston 12 are compressed. The impact force received by the upper connecting part 1 is gradually alleviated by means of the elastic force of the first spring 9 and the resistance generated by the air compression in the space below the first piston 12, thereby playing a buffering role.

[0023] The shock absorber rod 3 also includes a buffer portion 15, in which a second chamber 16 is arranged. The second chamber 16 is connected to the first chamber 10 below the first piston 12 through a first connecting pipe 17. The first connecting pipe 17 extends into the second chamber 16 and is sealed at the end. A first check valve 18 and a second check valve 19 are installed on the outer wall of the first connecting pipe 17 in the second chamber 16. The first check valve 18 is unidirectionally connected from the inside of the first connecting pipe 17 to the second chamber 16, and the second check valve 19 is unidirectionally connected from the second chamber 16 to the inside of the first connecting pipe 17. The flow rate of the first check valve 18 is greater than the flow rate of the second check valve 19. When the first piston 12 moves downward, the air at the bottom of the first piston 12 is compressed and enters the second chamber 16 through the first connecting pipe 17. When entering the second chamber 16, it enters through the first check valve 18. After the upper connecting part 1 moves down a certain distance and the first spring 9 and the compressed air have completed buffering the impact force, the first spring 9 and the compressed air will push the upper rod body 7 to move 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, the speed of the upper rod body 7 moving upward will be limited when the upper rod body 7 is reset, so as to mitigate the upward impact force generated by the elastic potential energy of the first spring 9 on the upper rod body 7. In this way, the shock absorbing rod 3 can achieve excellent shock absorbing effect in the whole shock absorbing process.

[0024] The shock-absorbing rod 3 also includes a transition portion 20, in which a third chamber 21 is arranged. The third chamber 21 is connected to the first chamber 10 below the first piston 12 through 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 barometer 23 for monitoring the air pressure of the third chamber 21 is installed on the side of the transition portion 20. By setting the transition portion 20, on the one hand, when the upper rod body 7 is initially subjected to impact force, the upper rod body 7 will move downward quickly for a distance, causing the air below the first piston 12 to be compressed violently. With the help of the third chamber 21, it can be used as a buffer space to alleviate this part of the compression, avoiding the air temperature rise caused by the violent air compression. By setting the electronic barometer 23, the air pressure state during the buffering process and the air pressure state during normal use can be monitored. Since more than two shock-absorbing rods 3 are arranged between the upper connecting part 1 and the lower connecting part 2, if the air pressure of the third chamber 21 is different when the two shock-absorbing rods 3 are not impacted, it means that the amount of air under the first piston 12 is different. Thus, when impacted, due to the different air pressures, the resistance generated by the compressed air under the first piston 12 is different, resulting in different forces on each upper rod body 7, which will cause the upper rod body 7 with the greatest force to be damaged in advance. Therefore, after the electronic barometer 23 monitors different air pressures, the air pressure can be adjusted to make all shock-absorbing rods 3 evenly stressed.

[0025] The shock absorber rod 3 also includes an inflation tube 24 and a through-type screw rod 31 motor 25. The inflation tube 24 is vertically installed at the upper end of the buffer part 15, and the lower end of the inflation tube 24 is connected to the second chamber 16. The inner wall of the inflation 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 connected to the upper side of the support ring 26, and the upper side is connected with a sealing block 30 matching the center hole of the sealing ring 28. The through-type screw rod 31 motor 25 is installed at the upper end of the inflation tube 24. The screw rod 31 of the through-type screw rod 31 motor 25 penetrates into the inflation tube 24 and is connected to the second piston 29. The outer wall of the second piston 29 is sealed and slidably connected to the inner wall of the inflation tube 24 up and down. 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, and the third one-way valve is unidirectional from top to bottom. The through-type screw rod 31 motor 25 can drive the screw rod 31 to move up and down in the motor, thereby driving the second piston 29 to move up and down in the inflation tube 24. When the inflation tube 24 and the through-type screw rod 31 motor 25 are not used, the second piston 29 is pushed to touch and fit with the sealing ring 28 by means of the second spring 27, so that the second chamber 16 is in a sealed state to avoid gas leakage. When the second chamber 16 needs to be inflated, the through-type screw rod 31 motor 25 drives the screw rod 31 to move 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, the second spring 27 will be driven to be compressed, so that the air enters the second chamber 16 through the center hole of the sealing ring 28. When the through-type screw rod 31 motor 25 drives the second piston 29 to move upward, the air can enter the lower side of the second piston 29 by means of the third one-way valve, and the second spring 27 will push the sealing block 30 sealing column sealing ring 28 center hole. Inflation can be completed by repeatedly driving the second piston 29 to move up and down. During the use of the connection assembly, although the first piston 12, the sliding hole 11 and other positions are sealed, the belt is a movable link, which inevitably causes partial air leakage after long-term use. Therefore, through the cooperation of the inflation tube 24 and the through-type screw rod 31 and the motor 25, each shock-absorbing rod 3 can be quickly restored to the working air pressure state, and the operator does not need to open the connection assembly for manual inflation.

[0026] The diameter of the central hole of the sealing ring 28 gradually decreases from bottom to top, the shape of the sealing block 30 is set to be a truncated cone that matches the central hole of the sealing ring 28, and a sealing layer is provided on the side wall of the sealing block 30. With such a structure, the performance between the sealing block 30 and the sealing ring 28 can be made better.

[0027] An upper guide rod 33 is vertically arranged downward at the bottom of the upper installation groove 4, and a lower guide rod 34 is vertically arranged upward at the bottom of the lower installation groove 5. A guide hole 35 is arranged at the upper end of the lower guide rod 34, and the lower end of the upper guide rod 33 is slidably arranged in the guide hole 35. By arranging the upper wire rod and the lower guide rod 34, the up and down movement of the upper connecting part 1 and the lower connecting part 2 can be guided, so as to avoid the damage to the shock absorbing rod 3 caused by the misaligned movement.

[0028] An upper connecting plate 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 plate 36. A lower connecting plate 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 plate 38. An upper connecting hole 40 and a lower connecting hole 41 are respectively arranged at the upper and lower ends of the shock absorbing 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.
