Description

Technical Field

[0001] The present invention relates to the technical field of gas spring production, and in particular to high-performance gas spring assembly production equipment. Background Art

[0002] A gas spring is an industrial accessory that can perform functions such as support, cushioning, braking, height adjustment, and angle adjustment. Depending on its characteristics and application areas, a gas spring is also called a support rod, gas support, angle adjuster, gas pressure rod, damper, etc. It consists of a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, a filler (inert gas or an oil-gas mixture), an in-cylinder control element, an out-of-cylinder control element (referring to a controllable gas spring), and a joint. The principle is to fill a closed pressure cylinder with an inert gas or an oil-gas mixture so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and to use the pressure difference generated by the cross-sectional area of ​​the piston rod being smaller than the cross-sectional area of ​​the piston to achieve the movement of the piston rod. Due to the fundamental difference in principle, gas springs have the advantages of relatively slow speed, little change in dynamic force, and easy control over ordinary springs.

[0003] The guide sleeve of a gas spring is typically made of metal or engineering plastics, and its primary functions include guiding, supporting, sealing, and lubricating. During gas spring assembly and production, an O-ring must be placed on the outer wall of the guide sleeve to ensure its sealing and other functions. Conventional installation of gas spring sealing O-rings typically relies on a mechanical support mechanism (such as a claw or push rod) to forcibly open the O-ring and then press it into the plunger sleeve. However, elastic materials such as nitrile rubber undergo nonlinear deformation when expanded, leading to the following problems: 1. It is difficult to adaptively adjust the expansion range to accommodate different sizes of sealing O-rings, requiring frequent fixture replacement, otherwise the O-ring can easily be overstretched or torn. 2. After expansion, the seal elastically retracts due to the material, and after disengaging from the support mechanism, it may deviate from the preset installation position, resulting in a loose fit between the seal ring and the inner wall of the plunger sleeve, leading to the risk of subsequent air leakage.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-14The utility model provides a high -performance gas spring assembly production equipment, including operation platform 1, operation platform 1 is rotationally arranged with the transposition mechanism for switching the position of guide sleeve 34, assembly mechanism is used for installing O ring 38 on guide sleeve 34, including the fixed disc 12 of operation platform 1, six support frames 16 are slidably arranged on the fixed disc 12, the bottom of each support frame 16 is rotationally arranged with the extension plate 25, and each extension plate 25 is correspondingly arranged with the positioning rotation mechanism between each support frame 16, and the fixed disc 12 has the first stroke, the second stroke and the third stroke of moving the extension plate 25, in the first stroke, the extension plate 25 is adjusted to the position of guide sleeve 34 to make guide sleeve 34 align with O ring 38 and adaptively adjust the opening amplitude of O ring 38, in the second stroke, the positioning rotation mechanism turns over and drives the extension plate 25 to make O ring 38 move to guide sleeve 34, in the third stroke, the positioning rotation mechanism locks the extension plate 25, and makes the extension plate 25 push O ring 38 to the designated position on guide sleeve 34,The shifting mechanism is used to move the guide sleeve 34 to the installation position below the fixed plate 12. The fixed plate 12 can move up and down on the operating table 1. The six support frames 16 are evenly arranged in a circle on the fixed plate 12. The support frame 16 is rotated away from the end of the fixed plate 12 to be provided with an expansion plate 25. The bottom of the support frame 16 and the top of the expansion plate 25 are both set to rounded corners. A set of positioning and rotating mechanisms are provided between each expansion plate 25 and the corresponding support frame 16. In the initial state, both sides of each expansion plate 25 are flush with both sides of the support frame 16. At this time, the expansion plate 25 can be rotated. When in use, each expansion plate 25 is rotated so that the angle between it and the corresponding support frame 16 is 135 degrees. When the expansion plate 25 is in the shape of an O-ring 38 and the guide sleeve 34 is in the shape of a trumpet with the opening downward, the expansion plate 25 is fixed in angle by the positioning and rotating mechanism, and then the O-ring 38 adapted to the guide sleeve 34 is placed on the supporting structure, and the O-ring 38 is supported by the upper wall of each expansion plate 25. Then, the guide sleeve 34 is moved to the specified position by the transposition mechanism. In the first stroke, the fixed plate 12 is controlled to move downward to approach the guide sleeve 34. As the fixed plate 12 moves, the bottom wall of the expansion plate 25 abuts against the top of the guide sleeve 34, and the fixed plate 12 continues to move downward. Since the expansion plates 25 are in an inclined state at this time, the guide sleeve 34 can be moved by each expansion plate 25. The O-ring 38 is moved to the middle position of each expansion plate 25 and aligned with the O-ring 38. In the second stroke, the fixed plate 12 is continued to be controlled to move downward, and then the top of the guide sleeve 34 is separated from the expansion plate 25 and moved between the support frames 16. The O-ring 38 is stretched, and the fixed plate 12 continues to move downward to lift the positioning rotation mechanism through the top of the guide sleeve 34. At this time, the expansion plate 25 is unlocked, and the retraction elasticity of the O-ring 38 makes the expansion plate 25 become vertically parallel to the support frame 16 again. At this time, the inner wall of the expansion plate 25 abuts the outer wall of the guide sleeve 34, and the O-ring 38 is also sleeved on the outer wall of each expansion plate 25. Since the thickness of the expansion plate 25 is fixed, the O-rings 38 of different sizes are stretched at this time. The radius of the expansion plate 25 is always greater than the radius of the adapted guide sleeve 34 by the thickness of the expansion plate 25, thereby achieving the adaptive expansion amplitude of the O-ring 38 and preventing the O-ring 38 from being excessively expanded or torn. As the positioning rotation mechanism continues to move upward, the expansion plate 25 rotates 45 degrees in the direction close to the guide sleeve 34 and locks it. At this time, the bottom of each expansion plate 25 abuts against the guide sleeve 34, and each expansion plate 25 forms a trumpet shape with an opening upward. At this time, since the expansion amplitude of the expansion plate 25 is greater than the diameter of the guide sleeve 34, the O-ring 38 automatically moves toward the end of the expansion plate 25 abutting against the guide sleeve 34 due to its own elasticity, and detaches from the bottom of the expansion plate 25 and moves onto the guide sleeve 34;In the third stroke, when the O-shaped ring 38 is sleeved on the guide sleeve 34, continue to move the fixed disc 12 downward, at this time the O-shaped ring 38 is below the bottom of each expansion plate 25, continue to move the fixed disc 12 downward, the bottom of the expansion plate 25 abutting against the guide sleeve 34 will push the O-shaped ring 38 to move downward, the guide sleeve 34 is provided with an annular clamping groove 341 at the preset installation position, when the O-shaped ring 38 is pushed down to the position of the annular clamping groove 341, it will be clamped into the clamping groove 341, at this time the position of the O-shaped ring 38 is fixed at the preset installation position, the position of the bottom of each expansion plate 25 abutting against the guide sleeve 34 is provided with flexible material, on the one hand, it can prevent scratching the guide sleeve 34, on the other hand, when the O-shaped ring 38 is clamped into the clamping groove 341, the flexible material abutting against the O-shaped ring 38 will be deformed, at this time the deformed flexible material is not enough to push the O-shaped ring 38 out of the clamping groove 341, it should be noted that when the O-shaped ring 38 is not clamped into the clamping groove 341, the flexible material will be deformed, but due to the protrusion of the O-shaped ring 38, the flexible material will still be able to push the O-shaped ring 38 to move after being deformed to the limit.

[0035] Further, the operating table 1 is fixedly provided with a feeding frame 35, the feeding frame 35 is fixedly provided with a circular table 36, the circular table 36 is provided with six L-shaped grooves 37, and the operating table 1 is also fixedly provided with a second feeding mechanical arm 5; the middle of the circular table 36 is hollow, the circular table 36 can place O-shaped rings 38 of different sizes, when it is needed to move the O-shaped ring 38 to be installed to the expansion plate 25, the second feeding mechanical arm 5 is used to place the O-shaped ring 38 on the circular table 36, then the fixed disc 12 is moved to be above the circular table 36, the fixed disc 12 is moved downward, at this time the expansion plate 25 is parallel to the support frame 16, each expansion plate 25 surrounds a cylinder, with the downward movement of the fixed disc 12, each expansion plate 25 passes through the middle of the O-shaped ring 38 and extends into the feeding frame 35, when each expansion plate 25 abuts against the bottom wall of the feeding frame 35, each expansion plate 25 begins to rotate outward, when the included angle between each expansion plate 25 and the corresponding support frame 16 becomes 135 degrees, the positioning rotating mechanism moves downward to clamp the expansion plate 25, at this time the angle of the expansion plate 25 is fixed, then the fixed disc 12 is moved upward, each expansion plate 25 passes through the corresponding L-shaped groove 37, then the expanded expansion plate 25 lifts the O-shaped ring 38 placed on the circular table 36, and then the fixed disc 12 is moved to be above the guide sleeve 34 of the O-shaped ring 38 to be installed.

[0036] Specifically, the bottom wall of the feeding frame 35 is fixedly provided with an abutting table 39; the abutting table 39 is in the shape of a circular table 36, when each expansion plate 25 abuts against the upper surface of the abutting table 39, the surface of the obliquely arranged abutting table 39 can make the expansion plate 25 rotate outward, with the downward movement of the fixed disc 12, the abutting table 39 makes each expansion plate 25 gradually rotate by 45 degrees, so that the included angle between the expansion plate 25 and the support frame 16 is 135 degrees.

[0037] In another embodiment of the present application: a torsion spring 24 is fixedly arranged between the top of each expansion plate 25 and the bottom of each support frame 16; as shown, two torsion springs 24 are arranged at the top of each expansion plate 25, and a torsion spring 24 is arranged between the two sides of the top of each expansion plate 25 and the bottom of the corresponding support frame 16. In the initial state, each torsion spring 24 aligns each expansion plate 25 with the corresponding support frame 16. When the expansion plate 25 rotates, the corresponding torsion spring 24 is twisted. When the expansion plate 25 is loosened, the torsion spring 24 can make the expansion plate 25 return to the vertical state again. Figure 14

[0038] Specifically, a first gear 18 is rotatably arranged on each side of each support frame 16, a second gear 21 is fixedly arranged at the top of each expansion plate 25, and a synchronous tooth belt 22 is drivingly arranged between each first gear 18 and second gear 21 in a one-to-one correspondence. Each second gear 21 is rotatably connected to the side wall of the corresponding support frame 16, the first gear 18 is above the second gear 21, the synchronous tooth belt 22 is sleeved between the first gear 18 and the second gear 21 on the same side of the support frame 16, and the synchronous tooth belt 22 is engaged with the corresponding first gear 18 and second gear 21. When the expansion plate 25 rotates, it drives the corresponding second gear 21 to rotate. At this time, the synchronous tooth belt 22 drives the corresponding first gear 18 to rotate. When the positioning rotation mechanism rises to a certain height, it will push the corresponding first gear 18 to rotate. At this time, the synchronous tooth belt 22 drives the second gear 21 to rotate, so that the expansion plate 25 rotates 45 degrees towards the direction of the guide sleeve 34.

[0039] Further, a lifting groove 17 is formed in each support frame 16, and the positioning rotation mechanism includes two connecting discs 19 rotatably arranged in each lifting groove 17, two first abutting rods 20 fixedly arranged between the two connecting discs 19, each connecting disc 19 fixedly connected to each first gear 18 in a one-to-one correspondence, and two second abutting rods 23 fixedly arranged at the top of each expansion plate 25. Figure 10 As shown, the two first abutting rods 20 on the same support frame 16 are symmetrically arranged, and the two second abutting rods 23 at the top of the same expansion plate 25 are also symmetrically arranged. In the initial state, the included angle between the connecting line between the two first abutting rods 20 and the vertical support frame 16 is 45 degrees, and the included angle between the connecting line between the two second abutting rods 23 and the vertical support frame 16 is also 45 degrees.

[0040] ​Furthermore, a limit block 30 is fixedly provided on the top of each expansion plate 25; the limit block 30 is fixedly provided on the top outer wall of the corresponding expansion plate 25, and the limit block 30 can prevent the O-ring 38 from moving from the expansion plate 25 to the support frame 16. At the same time, when the expansion plate 25 rotates in the direction close to the guide sleeve 34, the limit block 30 can squeeze the O-ring 38 downward by a certain distance, thereby preventing the O-ring 38 from moving to the position where the expansion plate 25 is rotatably connected to the support frame 16, ensuring that when the expansion plate 25 rotates toward the guide sleeve 34, the O-ring 38 can move to the guide sleeve 34 by its own elastic force.

[0041] Specifically, a positioning plate 26 is slidably provided in each lifting slot 17, a telescopic rod 28 is fixedly provided on the side of each positioning plate 26 away from the limit block 30, a moving block 29 is provided on the side of the fixed plate 12 close to the support frame 16, and a side of each telescopic rod 28 away from the positioning plate 26 is fixedly connected to the moving block 29, and a second spring 40 is fixedly provided between the moving block 29 and the fixed plate 12; a top plate 27 is fixedly provided on the side of each positioning plate 26 close to the telescopic rod 28, as shown in FIG. Figure 10As shown, in the initial state, the line between the two second abutting rods 23 on the same support frame 16 and the line between the two first abutting rods 20 have an angle of 45 degrees with the support frame 16, at this time the expansion plate 25 is flush with the support frame 16, by pressing the moving block 29 down through the second spring 40, the moving block 29 drives the corresponding positioning plate 26 to move down through the telescopic rod 28, so that the bottom of the positioning plate 26 abuts against the second abutting rod 23 above, the elastic force of the second spring 40 is smaller than that of the torsion spring 24, so at this time the expansion plate 25 will not rotate, when the bottom of the expansion plate 25 abuts against the abutting table 39 to generate counterclockwise rotation, the angle between the line between the two second abutting rods 23 and the support frame 16 gradually changes to 90 degrees, when the angle between them changes to 90 degrees, the positioning plate 26 is moved down through the second spring 40, at this time the bottom of the positioning plate 26 is clamped between the two second abutting rods 23, the two second abutting rods 23 and the positioning plate 26 cannot rotate, so as to fix the angle between the expansion plate 25 and the support frame 16 at 135 degrees, facilitating lifting the O-ring 38 on the circular table 36, when the O-ring 38 is lifted to the guide sleeve 34, the fixed disc 12 is moved downward, the bottom wall of the expansion plate 25 pushes the guide sleeve 34 to move to the position directly below the O-ring 38, then through the abutment between the bottom of the expansion plate 25 and the guide sleeve 34, each support frame 16 is spread outward until the inner wall of the support frame 16 is aligned with the outer wall of the guide sleeve 34, at this time the fixed disc 12 is continuously moved downward, the top of the guide sleeve 34 enters the middle of each support frame 16, the top of the guide sleeve 34 pushes the top plate 27 to move upward, so that the positioning block moves upward, after the positioning block moves a certain distance, the bottom thereof is separated from the second abutting rod 23, at this time each expansion plate 25 is attached to the outer wall of the guide sleeve 34 through the elastic force of the torsion spring 24 and the O-ring 38, so that each first abutting rod 20 and the second abutting rod 23 returns to the initial position, the top of the positioning plate 26 is provided with an inclined surface on the side close to the first abutting rod 20, as the positioning plate 26 moves upward, the inclined surface at the top of the positioning plate 26 abuts against the first abutting rod 20 on the upper side, and pushes the first abutting rod 20 on the upper side to rotate clockwise around the shaft center of the first gear 18 through the inclined surface, when the first abutting rod 20 on the upper side rotates clockwise by 45 degrees, the first abutting rod 20 on the lower side abuts against the side wall of the positioning plate 26, at this time the first abutting rod 20 on the upper side is just moved to the lower end of the inclined surface, when the first abutting rod 20 rotates clockwise by 45 degrees, the second gear 21 is driven to rotate clockwise by 45 degrees through the first gear 18 and the synchronous tooth belt 22, at this time the expansion plate 25 rotates by 45 degrees towards the guide sleeve 34, so that the O-ring 38 moves to the guide sleeve 34, as the positioning plate 26 continues to move upward, the two first abutting rods 20 abut against the side wall of the positioning plate 26, so that the first gear 18 cannot rotate, at this time the angle of the expansion plate 25 is also fixed, as the fixed disc 12 continues to move downward, the bottom of the expansion plate 25 pushes the O-ring 38 to the slot 341 in the guide sleeve 34, completing the alignment, then the fixed disc 12 is controlled to move upward, and the next O-ring 38 assembly is performed.

[0042] In another embodiment of the present invention: six sliding grooves 13 are opened on the fixed plate 12, and a slider 14 is slidably set in each sliding groove 13, and each slider 14 is fixedly connected to each support frame 16 in a one-to-one correspondence, and a first spring 15 is fixedly set between each slider 14 and the fixed plate 12; when the guide sleeve 34 pushes each support frame 16 to move outward through the bottom wall of the expansion plate 25, the support frame 16 drives the corresponding slider 14 to move, and each first spring 15 is stretched. When the O-ring 38 is installed, the fixed plate 12 moves up and separates from the guide sleeve 34. At this time, the first springs 15 gather each support frame 16 back to the initial position, thereby facilitating the next assembly.

It does not need to be clamped separately and can adapt to guide sleeves 34 of different sizes. The expansion plate 25 can be inserted into the slot 33, so that the support frame 16 can Move down a sufficient distance along the guide sleeve 34 to complete the assembly and alignment of the O-ring 38. When the discharge box 31 moves to the installation station, the discharge box 31 and the loading rack 35 are on both sides of the hydraulic cylinder 10. The hydraulic cylinder 10 controls the lifting and lowering of the fixed plate 12. Now, the hydraulic cylinder 10 is moved down to lift the O-ring 38 on the round table 36, and then the second servo motor 7 is controlled to drive the hydraulic cylinder 10 to rotate so that the fixed plate 12 rotates to the top of the guide sleeve 34. Then, the hydraulic cylinder 10 is controlled to move down to install the O-ring 38 on the guide sleeve 3 4 and then move upwards, and then the fixed plate 12 is returned to the top of the circular table 36 again by the second servo motor 7.

[0044] Working principle: When the O-ring 38 needs to be installed on the guide sleeve 34, first control the fixed disk 12 to move downward, the expansion plate 25 moves downward to abut against the abutment 39 and rotates 45 degrees counterclockwise, then the positioning plate 26 is inserted between the two second abutment rods 23, the angle of the expansion plate 25 is locked, the fixed disk 12 is moved upward, the expansion plate 25 lifts the O-ring 38 on the round table 36, then the fixed disk 12 is moved to the guide sleeve 34, and the fixed disk 12 is moved downward again. When the fixed disk 12 moves downward, the guide sleeve 34 is pushed to the bottom wall of the expansion plate 25 to be directly below the O-ring 38. As the fixed disk 12 continues to move downward, the top of the guide sleeve 34 pushes the positioning plate 26 to move upward. At this time, the expansion plate 25 is unlocked and affixed to the outer wall of the guide sleeve 34, and the positioning plate 26 continues to move upward and abuts against the first abutting rod 20, pushing the first abutting rod 20 to rotate, thereby driving the expansion plate 25 to rotate 45 degrees in the direction close to the guide sleeve 34 through the first gear 18, the synchronous toothed belt 22, and the second gear 21. At this time, the O-ring 38 automatically moves onto the guide sleeve 34, and then the angle of the expansion plate 25 is fixed through the abutment of the two first abutting rods 20 and the positioning plate 26. The fixed plate 12 continues to move downward, and the O-ring 38 on the guide sleeve 34 is pushed into the slot 341 through the bottom of the expansion plate 25 to achieve alignment. Then, the fixed plate 12 is controlled to return to the initial position. When the support frame 16 is separated from the guide sleeve 34, the first spring 15, the second spring 40, and the torsion spring 24 are used to return each component to its initial position.
