Description

Technical Field

[0001] This invention belongs to the field of spring processing technology, and relates to a tension gas spring and its processing device. Background Technology

[0002] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. It mainly consists of a pressure cylinder, piston rod, piston, sealing guide sleeve, filler, internal control elements, external control elements, and connectors. The principle is to fill the sealed pressure cylinder with inert gas or an oil-gas mixture, making the pressure inside the chamber several times or tens of times higher than atmospheric pressure. The piston rod's movement is achieved by utilizing the pressure difference created by the smaller cross-sectional area of ​​the piston rod compared to the piston's cross-sectional area.

[0003] Currently, when processing gas spring cylinder components, a long steel pipe is cut to a fixed length using cutting equipment to form the required cylinder component. During the transportation or processing of the steel pipe, due to its long length, slight bending deformation can easily occur in some areas. This deformation cannot be judged directly by the naked eye, and the straightness of the cylinder directly affects the subsequent piston sealing assembly. After being cut to a certain length, it is mostly judged manually by visual inspection, which requires long-term work experience. However, sometimes inspection errors can occur, affecting subsequent processing and assembly. Moreover, current gas springs are inconvenient to install and adjust, and it is not easy to adjust the distance between the two ends. The same model cannot meet the needs of different applications, resulting in low practicality. Therefore, we propose a tension gas spring and its processing device to solve the above-mentioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problems that the straightness detection of traditional cylinders mostly relies on visual judgment, which has poor detection accuracy, low efficiency, and is time-consuming and labor-intensive; and that the current gas springs are not flexible enough in installation and are inconvenient to adjust, resulting in low practicality, this invention provides a tension gas spring and its processing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing apparatus for a tension gas spring, comprising:

[0006] Mounting plate;

[0007] A rotating ring is rotatably connected to one side of the mounting plate;

[0008] The drive mechanism, mounted on the mounting plate, is used to drive the rotating ring to rotate.

[0009] Multiple detection mechanisms are arranged in a ring at equal intervals on the side wall of the rotating ring to detect the straightness of the cylinder. The detection mechanisms can automatically clamp and fix the cylinder, and can automatically release the clamping of the cylinder during the rotation of the rotating ring to complete the automatic unloading.

[0010] Furthermore, the driving mechanism includes a drive motor that is fixedly mounted on the side of the mounting plate away from the rotating ring via a support plate. The output shaft of the drive motor passes through the mounting plate and is fixedly fitted with a transmission gear. An external toothed ring that meshes with the transmission gear is fixedly fitted on the outer wall of the rotating ring.

[0011] Furthermore, the detection mechanism includes two guide rods that slide through one side of the rotating ring. The two guide rods are fixedly connected to the same connecting seat at one end located outside the rotating ring. A detection rod for detecting the straightness of the cylinder inner diameter is fixedly connected to the side of the connecting seat away from the guide rods.

[0012] Furthermore, a push rod that slides through one side of the rotating ring is fixedly connected to one side of the connecting seat.

[0013] Furthermore, a connecting plate is fixedly sleeved on the outer wall of the connecting seat away from the guide rod, and a fixed ring is fixedly connected to the side of the connecting plate away from the rotating ring. A sliding ring located inside the fixed ring is slidably sleeved on the outer wall of the detection rod. Two sliding rods are symmetrically fixedly connected to the side of the sliding ring near the rotating ring, and one end of each sliding rod slides through one side of the connecting plate and extends outward. A second spring is sleeved on the outer wall of each sliding rod located inside the fixed ring. The two ends of the second spring are fixedly connected to the sides of the sliding ring and the connecting plate that are close to each other. Two openings are symmetrically opened on the outer wall of the fixed ring. A sliding column slides through the inside of each opening. A pressure block is fixedly connected to the side of each sliding column that is close to each other. An arc-shaped groove for clamping the cylinder is opened on the side of each pressure block that is close to each other. One side of each sliding column is rotatably connected to the side of the sliding ring away from the rotating ring with the same first connecting rod, and one side of the first connecting rod is located inside the opening.

[0014] Furthermore, an anti-slip rubber pad is provided inside the arc-shaped groove.

[0015] Furthermore, the outer wall of the connecting seat has two symmetrically opened sliding grooves, and a locking rod slides through each of the two sliding grooves. One end of the locking rod located outside the connecting seat abuts against one side of the corresponding sliding rod. The sliding rod has a locking hole inside for positioning and engaging with the locking rod. The connecting seat has two symmetrically opened cavities that are respectively connected to the corresponding sliding grooves. Push rods slide through the interior of each of the two guide rods. One end of the push rod extends into the cavity and is rotatably connected to the same second connecting rod on one side of the corresponding locking rod. A third spring is sleeved on the outer wall of the push rod inside the cavity. The two ends of the third spring are fixedly connected to one side of the inner wall of the cavity and the outer wall of the push rod, respectively. A baffle that limits and abuts the push rod and guide rod is slidably sleeved on the outer wall of the top rod. Fixing blocks are fixedly connected to both sides of the baffle. Both fixing blocks are fixedly connected to the inner wall of the rotating ring.

[0016] Furthermore, two piston cylinders are symmetrically fixedly connected to the inner wall of the fixed ring. A piston block is slidably connected inside the piston cylinder. A connecting rod is fixedly connected to one side of the piston block. The other end of the connecting rod passes through one end of the piston cylinder and is fixedly connected to the side of the sliding ring near the rotating ring. An air outlet pipe is provided at the end of the piston cylinder away from the connecting rod. A one-way air outlet valve is installed on the air outlet pipe. An air inlet pipe is provided on the side of the piston cylinder near the air outlet pipe. A one-way air inlet valve is installed on the air inlet pipe. The inner diameter of the air inlet pipe is smaller than the inner diameter of the air outlet pipe.

[0017] A tension gas spring includes a cylinder, and the gas spring further includes:

[0018] A sealing guide sleeve is fixedly installed at one end inside the cylinder barrel;

[0019] The piston, with its seal sliding inside the cylinder, is located.

[0020] The piston rod has one end fixedly connected to the side of the piston near the sealing guide sleeve, and the other end slidingly passes through the sealing guide sleeve and extends to the outside of the cylinder.

[0021] The sealing plate is fixedly connected inside the cylinder to the side away from the sealing guide sleeve.

[0022] The connecting block is adjustable and located on the outer side of the cylinder barrel at the end furthest from the piston rod;

[0023] Two connectors are fixedly located at the ends of the piston rod and the connecting block that are far apart from each other, and are used to connect the entire gas spring.

[0024] Furthermore, the adjusting component includes a threaded adjusting ring rotatably connected to the side of the connecting block near the cylinder, and the threaded adjusting ring is threadedly connected to one end of the cylinder. A sleeve located inside the threaded adjusting ring is fixedly connected to one side of the connecting block, and a support rod is slidably connected through the sleeve. The end of the support rod away from the connecting block is fixedly connected to one side of the sealing plate.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. The processing device for tension gas spring disclosed in this invention can adjust the orientation of multiple sets of detection mechanisms by starting the drive motor to drive the rotating ring to rotate. By setting different orientations of the detection mechanisms, the cylinder can be inserted into the detection rod when it is being inspected. The straightness of the inner wall of the cylinder can be quickly detected by the detection rod. This reduces the fatigue of relying on manual visual inspection and improves the accuracy and efficiency of the inspection.

[0027] 2. The processing device for a tension gas spring disclosed in this invention can automatically clamp the cylinder by inserting it onto the detection rod. After the rotating ring drives the detection mechanism to rotate and change its position, the clamping of the cylinder can be automatically released, achieving the effect of automatic unloading, which is convenient for centralized collection, avoids manual intervention, and improves the convenience of use.

[0028] 3. The processing device for a tension gas spring disclosed in this invention, through the setting of the piston cylinder, can prevent the sliding ring from rapidly resetting under the elastic force of the second spring during the process of releasing the cylinder from clamping, and avoid the cylinder being pushed out quickly, so that it falls slowly, thereby achieving the effect of protecting the cylinder.

[0029] 4. The tension gas spring disclosed in this invention can adjust the distance between the connecting block and the cylinder by rotating the threaded adjusting ring within the cylinder, thereby facilitating the adjustment of different installation lengths and installation in different positions; at the same time, the sliding fit between the support rod and the sleeve prevents rotation between the connecting block and the cylinder, ensuring stability during use.

[0050] Example 1

[0051] like Figures 3-4As shown, a processing device for a tension gas spring includes a mounting plate 1 and a rotating ring 2, the rotating ring 2 being rotatably connected to one side of the mounting plate 1. It also includes a drive mechanism mounted on the mounting plate 1 for driving the rotating ring 2 to rotate. The drive mechanism includes a drive motor 4 fixedly mounted on the side of the mounting plate 1 away from the rotating ring 2 via a support plate. The output shaft of the drive motor 4 passes through the mounting plate 1 and is fixedly fitted with a transmission gear 5. An external toothed ring 3, meshing with the transmission gear 5, is fixedly fitted onto the outer wall of the rotating ring 2. Starting the drive motor 4 drives the transmission gear 5 to rotate, which in turn drives the rotating ring 2 to rotate through meshing with the external toothed ring 3. During this process, the operation settings of the drive motor 4 can be adjusted to control the intermittent directional rotation of the rotating ring 2, enabling multiple detection mechanisms to perform sequential switching between upper and lower positions.

[0052] like Figures 3-5 As shown, the processing device also includes multiple sets of detection mechanisms arranged in a ring at equal intervals on the side wall of the rotating ring 2, used to detect the straightness of the cylinder 101. These detection mechanisms can automatically clamp and fix the cylinder 101, and automatically release the clamping during the rotation of the rotating ring 2, completing automatic unloading. The detection mechanism includes two guide rods 7 that slide through one side of the rotating ring 2. One end of each guide rod 7 located outside the rotating ring 2 is fixedly connected to the same connecting seat 8. A detection rod 16 for detecting the straightness of the inner diameter of the cylinder 101 is fixedly connected to the side of the connecting seat 8 away from the guide rods 7. The cut cylinder 101 is inserted into the detection rod 16 to detect the straightness of the inner wall of the cylinder 101. If the insertion is obstructed, it indicates that the straightness of the inner wall is substandard.

[0053] Example 2

[0054] This embodiment is a further improvement on the previous embodiment: such as Figures 3-4 As shown, a processing device for a tension gas spring includes a mounting plate 1 and a rotating ring 2, the rotating ring 2 being rotatably connected to one side of the mounting plate 1. It also includes a drive mechanism mounted on the mounting plate 1 for driving the rotating ring 2 to rotate. The drive mechanism includes a drive motor 4 fixedly mounted on the side of the mounting plate 1 away from the rotating ring 2 via a support plate. The output shaft of the drive motor 4 passes through the mounting plate 1 and is fixedly fitted with a transmission gear 5. An external toothed ring 3, meshing with the transmission gear 5, is fixedly fitted onto the outer wall of the rotating ring 2. Starting the drive motor 4 drives the transmission gear 5 to rotate, which in turn drives the rotating ring 2 to rotate through meshing with the external toothed ring 3. During this process, the operation settings of the drive motor 4 can be adjusted to control the intermittent directional rotation of the rotating ring 2, enabling multiple detection mechanisms to perform sequential switching between upper and lower positions.

[0055] like Figures 3-5As shown, the processing device also includes multiple sets of detection mechanisms arranged in a ring at equal intervals on the side wall of the rotating ring 2, used to detect the straightness of the cylinder 101. These detection mechanisms can automatically clamp and fix the cylinder 101, and automatically release the clamping during the rotation of the rotating ring 2, completing automatic unloading. The detection mechanism includes two guide rods 7 that slide through one side of the rotating ring 2. One end of each guide rod 7 located outside the rotating ring 2 is fixedly connected to the same connecting seat 8. A detection rod 16 for detecting the straightness of the inner diameter of the cylinder 101 is fixedly connected to the side of the connecting seat 8 away from the guide rods 7. The cut cylinder 101 is inserted into the detection rod 16 to detect the straightness of the inner wall of the cylinder 101. If the insertion is obstructed, it indicates that the straightness of the inner wall is substandard.

[0056] like Figures 5-6 As shown, in this invention, a push rod 9 that slides through one side of the rotating ring 2 is fixedly connected to one side of the connecting seat 8. A first spring 10 is sleeved on the outer wall of the push rod 9 inside the rotating ring 2. The two ends of the first spring 10 are fixedly connected to the inner wall of the rotating ring 2 and the outer wall of the push rod 9, respectively. A fixed post 6 located at the center of the inner side of the rotating ring 2 is fixedly connected to one side of the mounting plate 1. An arc-shaped protrusion 13 is provided on one side of the outer wall of the fixed post 6, which intermittently abuts against the push rod 9. When one end of the push rod 9 contacts the outer wall of the fixed post 6, the first spring 10 is in its initial state. When the rotating ring 2 rotates, causing the push rod 9 to rotate and abut against the arc-shaped protrusion 13, the push rod 9 can push the connecting seat 8 outward and compress the first spring 10, which facilitates the subsequent reset of the entire detection mechanism.

[0057] like Figure 6As shown, in this invention, a connecting plate 14 is fixedly sleeved on the outer wall of the connecting seat 8 away from the guide rod 7. A fixing ring 15 is fixedly connected to the connecting plate 14 away from the rotating ring 2. A sliding ring 17 located inside the fixing ring 15 is slidably sleeved on the outer wall of the detection rod 16. Two sliding rods 18 are symmetrically fixedly connected to the side of the sliding ring 17 near the rotating ring 2, and one end of each sliding rod 18 slides through one side of the connecting plate 14 and extends outward. A second spring 19 is sleeved on the outer wall of each sliding rod 18 located inside the fixing ring 15. The two ends of the fixed ring 15 are fixedly connected to the sides of the sliding ring 17 and the connecting plate 14 respectively. The outer wall of the fixed ring 15 has two symmetrical openings 20. The sliding column 21 slides through the interior of each opening 20. The ends of the two sliding columns 21 that are close to each other are fixedly connected to the pressure block 22. The sides of the two pressure blocks 22 that are close to each other are provided with arc-shaped grooves 24 for clamping the cylinder 101. One side of each sliding column 21 is rotatably connected to the side of the sliding ring 17 away from the rotating ring 2 by the same first connecting rod 23, and one side of the first connecting rod 23 is located inside the opening 20. When the cylinder 101 is inserted into the detection rod 16, it can push the sliding ring 17 inward to move, and at the same time drive the sliding rod 18 to move and squeeze the second spring 19. When the sliding ring 17 moves inward, it can also drive the sliding column 21 to slide inward through the first connecting rod 23, and bring the two pressure blocks 22 closer to each other. The arc-shaped grooves 24 are used to clamp the outer walls of the cylinder 101 on both sides.

[0058] like Figure 6 As shown, in this invention, two sliding grooves 26 are symmetrically formed on the outer wall of the connecting seat 8. A locking rod 27 slides through each of the two sliding grooves 26. One end of the locking rod 27 located outside the connecting seat 8 abuts against one side of the corresponding sliding rod 18. The sliding rod 18 has a locking hole 28 inside for positioning and engaging with the locking rod 27. Two symmetrical cavities 29 are formed inside the connecting seat 8, each communicating with a corresponding sliding groove 26. Push rods 30 slide through the interiors of both guide rods 7, with one end of the push rod 30 extending... The push rod 30 is rotatably connected to the inner wall of the cavity 29 and the same second connecting rod 31. The push rod 30 is fitted with a third spring 32 on the outer wall inside the cavity 29. The two ends of the third spring 32 are fixedly connected to the inner wall of one side of the cavity 29 and the outer wall of the push rod 30, respectively. The outer wall of the push rod 9 is slidably fitted with a baffle 12 that limits and blocks the push rod 30 and the guide rod 7. Both sides of the baffle 12 are fixedly connected with fixing blocks 11. Both fixing blocks 11 are fixedly connected to the inner wall of the rotating ring 2.

[0059] After the push rod 9 abuts against the arc-shaped protrusion 13, pushing the entire detection mechanism outward, the guide rod 7 and push rod 30 disengage from the baffle 12. When the cylinder 101 pushes the sliding ring 17 to slide inward, it simultaneously drives the sliding rod 18 to extend outward. When the locking hole 28 corresponds to the locking rod 27, since the third spring 32 is in a stretched state, the locking rod 27 will be pulled outward by the second connecting rod 31 under the elastic force of the third spring 32 and positioned and inserted into the locking hole 28, thus achieving the positioning effect of the sliding rod 18, thereby achieving the positioning effect of the sliding ring 17, and thus completing the automatic clamping effect of the cylinder 101. At the same time, the push rod 30 extends outward from one end of the guide rod 7 under the elastic force of the third spring 32. When the drive motor 4 is started, it drives the rotating ring... 2. After rotation, the push rod 9 disengages from the arc-shaped protrusion 13 and contacts the outer wall of the fixed column 6. At this time, the push rod 9 pulls the entire detection mechanism inward under the elastic force of the first spring 10, and drives the guide rod 7 and push rod 30 to move. The push rod 30 first contacts the baffle 12, and at the same time pushes the push rod 30 to move inward and stretches the third spring 32. The second connecting rod 31 pulls the clamping rod 27 inward again and disengages it from the positioning insertion of the clamping hole 28. At this time, the sliding rod 18 slides inward and resets under the elastic force of the second spring 19, and pushes the sliding ring 17 to move outward. Then, the first connecting rod 23 drives the pressure block 22 to disengage from the clamping of the cylinder 101, thereby achieving the effect of automatically releasing the clamping of the cylinder 101. Automatic feeding can be achieved without human intervention.

[0060] Example 3

[0061] This embodiment is a further improvement on the previous embodiment: such as Figure 10 As shown, an anti-slip rubber pad 25 is provided inside the arc-shaped groove 24. The anti-slip rubber pad 25 not only protects the outer wall of the cylinder 101 and prevents it from being scratched by friction during movement, but also improves the clamping effect.

[0062] Example 4

[0063] This embodiment is a further improvement on the previous embodiment: such as Figures 6-7As shown, two piston cylinders 33 are symmetrically fixedly connected to the inner wall of the fixed ring 15. A piston block 34 is slidably connected inside the piston cylinder 33. A connecting rod 35 is fixedly connected to one side of the piston block 34. The other end of the connecting rod 35 passes through one end of the piston cylinder 33 and is fixedly connected to the side of the sliding ring 17 near the rotating ring 2. An air outlet pipe 36 is provided at the end of the piston cylinder 33 away from the connecting rod 35. A one-way air outlet valve 37 is installed on the air outlet pipe 36. An air inlet pipe 38 is provided on the side of the piston cylinder 33 near the air outlet pipe 36. A one-way air inlet valve 39 is installed on the air inlet pipe 38, and the inner diameter of the air inlet pipe 38 is smaller than the inner diameter of the air outlet pipe 36. When the sliding ring 17 slides inward, it can push the piston block 34 to move through the connecting rod 35, and quickly discharge the air in the piston cylinder 33 through the exhaust pipe 36, thus not affecting the normal insertion of the cylinder 101. When the sliding ring 17 slides outward to reset, that is, when the cylinder 101 is released from clamping, the sliding ring 17 pulls the piston block 34 to move in the opposite direction through the connecting rod 35. Due to the setting of the one-way exhaust valve 37 and the one-way intake valve 39, the air in the piston cylinder 33 can only be discharged outward through the exhaust pipe 36, and the outside air can only be delivered inward through the intake pipe 38. Since the inner diameter of the intake pipe 38 is smaller than that of the exhaust pipe 36, the intake speed is relatively slower than the exhaust speed, thus ensuring that the sliding ring 17 resets slowly, avoiding the rapid ejection of the cylinder 101, and improving the protection of the cylinder 101.

[0064] Example 5

[0065] like Figures 1-2 As shown, a tension gas spring includes a cylinder 101 processed by the processing device. The gas spring also includes: a sealing guide sleeve 102, a piston 103, a piston rod 104, a sealing plate 105, a connecting block 106, and two connectors 110. The sealing guide sleeve 102 is fixedly disposed inside one end of the cylinder 101. The piston 103 is slidably disposed inside the cylinder 101. One end of the piston rod 104 is fixedly connected to the side of the piston 103 near the sealing guide sleeve 102, and the other end slidably passes through the sealing guide sleeve 102 and extends to the outside of the cylinder 101. The sealing plate 105 is fixedly connected inside the cylinder 101 on the side away from the sealing guide sleeve 102. The connecting block 106 is adjustablely disposed on the outside of the cylinder 101 away from the piston rod 104 by an adjusting member. The two connectors 110 are respectively fixedly disposed at the ends of the piston rod 104 and the connecting block 106 that are far apart from each other, for connecting the entire gas spring.

[0066] like Figure 2As shown, the adjusting component includes a threaded adjusting ring 109 rotatably connected to the connecting block 106 near the cylinder 101, and the threaded adjusting ring 109 is threadedly connected to one end of the cylinder 101. A sleeve 108 located inside the threaded adjusting ring 109 is fixedly connected to one side of the connecting block 106. A support rod 107 is slidably connected through the sleeve 108, and the end of the support rod 107 away from the connecting block 106 is fixedly connected to one side of the sealing plate 105. When it is necessary to adjust the installation length of the entire gas spring, the distance between the connecting block 106 and the cylinder 101 can be adjusted by rotating the threaded adjusting ring 109 within the cylinder 101, thereby facilitating the adjustment of different installation lengths and installation in different positions. After the connecting block 106 is installed through the connector 110, due to the sliding relationship between the support rod 107 and the sleeve 108, rotation between the connecting block 106 and the cylinder 101 will not occur, ensuring stability during use.
