Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, specifically to an assembly equipment for processing lifting gas springs. Background Technology

[0002] A lifting gas spring is a mechanical device that uses compressed gas as a power source and achieves smooth lifting, buffering, or height adjustment functions through changes in gas pressure within a sealed cavity. The core structure of a lifting gas spring includes a piston rod, a pressure cylinder, a piston, a sealing guide sleeve, and an inert gas or oil-gas mixture as filler. When an external force is applied to the piston rod, the gas is compressed or expanded, generating an elastic force that balances the external force, thus achieving smooth lifting. By controlling the gas flow through the valve body, the gas spring can be locked in any position.

[0003] The processing and assembly of lifting gas springs involves core processes such as piston rod assembly and gas spring bed bracket assembly. This requires specialized equipment for efficient and precise production. Gas spring piston rod assembly equipment automates the assembly of guide sleeves and piston rods, solving the problems of low efficiency and unstable pass rates associated with traditional manual assembly. End fittings are functional components of gas springs, used to connect the gas spring body to external devices. They are typically installed quickly at the piston rod end of the gas spring using threads or snap-fit ​​structures. End fittings consist of two core components: brackets and end tubes. They are made of materials such as stainless steel, galvanized steel, and powder metallurgy steel, and are compatible with various gas spring specifications. Precise structural design ensures stable connection and load transfer between devices.

[0004] Currently, existing technologies typically use threaded connections to connect end fittings to the piston rod end of the lifting gas spring. This requires workers to place the end fitting on the piston rod end of the lifting gas spring, then fix the lifting gas spring on an electric tightening machine, and finally tighten the end fitting using the electric tightening machine to assemble the end fitting with the lifting gas spring. However, the large amount of manual operation and the intermittent nature of the assembly process can easily affect the installation speed and continuity of the end fitting, thus affecting the assembly efficiency of the lifting gas spring. Therefore, this technology does not meet the current requirements. To address this, we propose an assembly equipment for processing lifting gas springs. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0033] According to some embodiments of this disclosure, an assembly device for processing lifting gas springs is provided, see reference. Figure 1 — Figure 11 As shown, the assembly equipment for processing the lifting gas spring includes a tightening machine 100 and a conveyor belt 110 disposed on the side of the tightening machine 100. The conveyor belt 110 is a technical means well known to those skilled in the art and will not be described in detail here. A mounting base 120 for fixing the lifting gas spring is fixedly installed on the upper side of the conveyor belt 110. A fixing component 130 is disposed inside the mounting base 120. The fixing component 130 includes a base plate 131 slidably disposed inside the mounting base 120, a connecting spring 132 connecting the base plate 131 and the inner wall of the mounting base 120, a first wedge block 133 slidably disposed inside the side wall of the mounting base 120 and fixedly connected to the base plate 131, a second wedge block 134 slidably disposed inside the side wall of the mounting base 120 and used in conjunction with the first wedge block 133, and a clamping piece 135 slidably disposed inside the side wall of the mounting base 120 and fixedly connected to the second wedge block 134. The clamping piece 135 is used to clamp and fix the lifting gas spring.

[0034] One end of the connecting spring 132 is fixedly connected to the base plate 131, and the other end of the connecting spring 132 is fixedly connected to the inner wall of the mounting base 120. The number of first wedge blocks 133 is set to several, and the several first wedge blocks 133 are evenly arranged in the circumferential direction in the side wall of the mounting base 120. The ends of the first wedge blocks 133 are all slidably inserted into the inner wall of the mounting base 120, and the ends of the first wedge blocks 133 are all fixedly connected to the side of the base plate 131. The inclined surface of the first wedge block 133 and the inclined surface of the second wedge block 134 are slidably engaged. A slider can be installed on the inclined surface of the second wedge block 134 (shown in the figure). A groove for cooperating with the slider can be opened on the inclined surface of the first wedge block 133 (shown in the figure). The slider is slidably engaged in the groove, thereby preventing the first wedge block 133 and the second wedge block 134 from separating. Alternatively, it can be designed according to the actual situation so that the inclined surfaces of the first wedge block 133 and the second wedge block 134 always slide and fit together without separating.

[0035] The tightening machine 100 has a first track groove 140 on its side. The first track groove 140 includes a first groove 141, a second groove 142 connected to one end of the first groove 141, a third groove 143 connected to the second groove 142, a fourth groove 144 connected to the third groove 143, and a fifth groove 145 connected to the fourth groove 144. The end of the fifth groove 145 is connected to the other end of the first groove 141. The first groove 141 is configured as an arc-shaped groove that slopes downward along the conveyor belt 110. The second groove 142 is configured as a horizontal groove that communicates with the lower end of the first groove 141. The third groove 143 is configured as an arc-shaped groove that slopes downward along the conveyor belt 110. The upward-facing arc-shaped grooves are configured such that the fourth groove 144 is an arc-shaped groove that slopes upward in the opposite direction of the conveyor belt 110, and the fifth groove 145 is a horizontal groove that communicates with the upper end of the fourth groove 144. A baffle 146 is rotatably arranged between the third groove 143 and the fourth groove 144. The baffle 146 is rotatably mounted on the inner wall of the tightening machine 100. The baffle 146 can only be flipped upward. A stop block (not shown in the figure) can be installed on the inner wall of the tightening machine 100 below the baffle 146, and the stop block contacts the lower surface of the baffle 146 to restrict the downward flipping of the baffle 146, so that the baffle 146 can only be flipped upward.

[0036] A first connecting rod 150 is slidably inserted into the first track groove 140. A first drive assembly 160 for driving the first connecting rod 150 is provided inside the tightening machine 100. The first drive assembly 160 includes a sleeve rod 161 slidably disposed inside the tightening machine 100 and slidably sleeved outside the first connecting rod 150; a lever 162 slidably inserted into the side wall of the tightening machine 100 and connected to the sleeve rod 161; a lever 163 fixedly installed on the outside of the mounting base 120 and intermittently abutting the lever 162; and a telescopic member 164 installed inside the tightening machine 100 and connected to the sleeve rod 161. The telescopic member 164 includes components fixedly installed inside the tightening machine 100 and filled with… The system includes an air-filled cylinder 1641, a plug 1642 slidably disposed inside the cylinder 1641, and a slide rod 1643 slidably inserted into the end of the cylinder 1641 and fixedly connected to the plug 1642. The end of the slide rod 1643 is fixedly connected to a sleeve rod 161. An insert rod 165 is fixedly installed on the outside of the sleeve rod 161. An insert shaft 166 is rotatably inserted into the end of the insert rod 165. Both ends of the insert shaft 166 are fixedly connected to the inner wall of the paddle 162. A torsion spring 167 is sleeved on the outside of the insert shaft 166. One end of the torsion spring 167 is fixedly connected to the inner wall of the baffle 146, and the other end of the torsion spring 167 is fixedly connected to the insert rod 165. The rigidity of the torsion spring 167 is greater than the resistance of the paddle 162 moving to the left.

[0037] A housing 170 for carrying end fittings is fixedly installed at the end of the first connecting rod 150. A ring 171 is rotatably arranged inside the housing 170. The inner ring of the ring 171 engages with a limiting piece 172. The number of limiting pieces 172 is set to several, and the limiting pieces 172 are evenly arranged circumferentially inside the housing 170. The upper side of the limiting piece 172 intermittently abuts against the bottom of the end fitting. When the limiting piece 172 is located under the end fitting, the bottom of the end fitting presses against the upper side of the limiting piece 172, so that the limiting piece 172 supports the end fitting. When the limiting piece 172 rotates away from the bottom of the end fitting, the supporting of the limiting piece 172 on the end fitting is released, so that the end fitting falls under its own weight, thereby causing the end fitting to detach from the lower side of the housing 170.

[0038] A rotating shaft 173 is fixedly installed inside the housing 170. A damping bearing 174 is interference-fitted at the end of the rotating shaft 173. There is rotational resistance between the inner and outer rings of the damping bearing 174. When there is no external force between the inner and outer rings of the damping bearing 174, the inner and outer rings of the damping bearing 174 can remain relatively stationary. This is a technical means well known to those skilled in the art and will not be described in detail here. A gear 175 is interference-fitted on the outer side of the damping bearing 174. The gear 175 meshes with the outer ring of the ring 171. A first rack 176 and a second rack 177 are fixedly installed on the outer wall of the tightening machine 100. The first rack 176 and the second rack 177 intermittently mesh with the gear 175, respectively.

[0039] The tightening machine 100 has a second track groove 180 on its side. The structure and dimensions of the second track groove 180 are the same as those of the first track groove 140. Similarly, a baffle 146 that can only be flipped upwards is rotatably installed inside the second track groove 180. A second connecting rod 190 is slidably inserted into the second track groove 180. The structure and dimensions of the second connecting rod 190 are the same as those of the first connecting rod 150. The tightening machine 100 also has a second drive assembly 200 for driving the second connecting rod 190. The structure and dimensions of the second drive assembly 200 are the same as those of the first drive assembly 160. A tightening head 210 for tightening end fittings is fixedly installed at the end of the second connecting rod 190. Similar to the function of an electric wrench, the core function of the tightening head 210 is to tighten or loosen bolts and nuts through an electric drive device. The end of the lifting gas spring is set as a threaded rod, and the inner wall of the end fitting is provided with a threaded groove that mates with the thread. By driving the end fitting to press down and rotate through the tightening head 210, the end fitting and the end of the lifting gas spring can be fixed by threaded connection. This is a technical means well known to those skilled in the art and will not be described in detail here. This realizes the assembly of the end fitting and the lifting gas spring. During the process of conveying the lifting gas spring through the conveyor belt 110, the end fitting is first put on the end of the lifting gas spring through the housing 170, and then the end fitting is tightened by the tightening head 210.

[0040] With the above technical solution, the assembly equipment for processing lifting gas springs provided in this disclosure, when in use, firstly, insert the lower end of the lifting gas spring into the mounting base 120. Through the weight of the lifting gas spring itself, the base plate 131 is pressed down, simultaneously compressing the connecting spring 132. The pressed-down base plate 131 causes the first wedge block 133 to move down. Through the cooperation of the first wedge block 133 and the second wedge block 134, the second wedge block 134 causes the clamping plates 135 to move closer together, thereby clamping and fixing the lifting gas spring. (Refer to...) Figure 1 As shown, the conveyor belt 110 drives the mounting base 120 and the lifting gas spring to move to the left. At the same time, the mounting base 120 drives the lever 163 to abut against the lever 162, pushing the lever 162 to the left in sync, so that the lever 162 drives the sleeve rod 161, the first connecting rod 150 and the housing 170 to move to the left in sync. The movement of the housing 170 is limited by the cooperation of the first connecting rod 150 and the first track groove 140. Since the first connecting rod 150 is slidably inserted into the sleeve 161, the first connecting rod 150 and the housing 170 can move up and down. When the first connecting rod 150 slides in the first groove 141, the housing 170 moves synchronously to the left with the lifting gas spring and gradually moves down towards the end of the lifting gas spring. When the first connecting rod 150 slides in the second groove 142, the housing 170 moves synchronously to the left with the lifting gas spring, causing the lower side of the housing 170 to be sleeved on the end of the lifting gas spring. At this time, the gear 175 meshes with the first rack 176, and through the interaction of the gear 175 and the first rack 176... The meshing causes gear 175 to rotate, and the meshing of gear 175 with ring 171 causes ring 171 to rotate. Subsequently, the meshing of ring 171 with limiting plate 172 causes limiting plate 172 to rotate away from the bottom of the end fitting, releasing the supporting effect of limiting plate 172 on the end fitting, allowing the end fitting to fall freely under its own weight, thus allowing the end fitting to be sleeved on the end of the lifting gas spring. At this time, gear 175 disengages from the first rack 176. When the first connecting rod 150 slides in the three grooves 143, the housing 170 moves to the left synchronously with the lifting gas spring and gradually moves upward away from the end of the lifting gas spring, and also away from the end fitting sleeved on the end of the lifting gas spring. Immediately afterwards, the first connecting rod 150 abuts against the lower side of the baffle 146, causing the baffle 146 to flip upwards, allowing the first connecting rod 150 to pass over the baffle 146 and enter the four slots 144. The baffle 146 also blocks the downward movement of the first connecting rod 150, preventing it from moving downwards and forcing it to move upwards along the four slots 144. As the conveyor belt 110 drives the mounting base 120 and the lever 163 to continue moving to the left, the first connecting rod 150, already positioned within the four slots 144, cannot move further to the left and comes to a stop. This causes the lever 163 to press against the paddle 162, rotating the paddle 162 and compressing the torsion spring 167. When the lever 163 passes the paddle 162, the paddle 162 resets under the restoring force of the torsion spring 167. Furthermore, the sleeve rod... As cylinder 161 moves to the left, it simultaneously moves slide rod 1643 and plug 1642 to the left, causing the air on the left side of plug 1642 in cylinder 1641 to be compressed and the air pressure to increase, while the air on the right side of plug 1642 in cylinder 1641 to be diffused and the air pressure to decrease. This gives plug 1642 and slide rod 1643 a rightward resetting force. During the process of sliding rod 1643 pulling sleeve 161 to the right to reset, first connecting rod 150 first moves to the right along the fourth groove 144 and rises, and then first connecting rod 150 slides along the fifth groove 145 to reset. This causes first connecting rod 150 to drive housing 170 to reset. Then, end fittings can be placed in housing 170 for continuous use. Similarly, when the housing 170 resets, the second drive assembly 200 drives the second connecting rod 190 to move synchronously to the left along with the lifting gas spring with the end fitting fitted on it. At the same time, through the cooperation of the second connecting rod 190 and the second track groove 180, the second connecting rod 190 drives the tightening head 210 to descend and fit onto the end fitting as it moves synchronously to the left along with the lifting gas spring. This allows the tightening head 210 to tighten the end fitting onto the end of the lifting gas spring. Finally, the tightening head 210 moves back up to reset. In summary, during the process of conveying the lifting gas spring by the conveyor belt 110, the housing 170 first carries the end fitting, which is then fitted onto the end of the lifting gas spring. Then, the tightening head 210 tightens the end fitting, achieving rapid and automatic assembly of the end fitting and the lifting gas spring. The assembly process is completed during uninterrupted conveying, improving the installation speed and continuity of the end fitting, thereby effectively improving the assembly efficiency of the lifting gas spring.
