Description

Technical Field

[0001] The utility model belongs to the technical field of gas springs, and more specifically relates to an installation system for an outer sleeve and a guide sleeve of a gas spring. Background Art

[0002] Gas spring is an industrial accessory that can support, buffer, brake, adjust height and angle, etc. Its principle is to fill an inert gas or oil-gas mixture in a closed cavity, so that the pressure in the cavity is several or dozens of times higher than the atmospheric pressure, and the cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston to generate a pressure difference to achieve the movement of the piston rod. Due to the fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, small dynamic force change (generally within 1:1.2), and easy control.

[0003] The existing gas spring is mainly composed of an outer sleeve, a core rod and a sealing guide sleeve. Among them, the sealing guide sleeve is a core component of the gas spring and is particularly important. During the assembly process of the gas spring, after the guide sleeve is pressed into the outer sleeve, the outer sleeve needs to be sent to the subsequent processing equipment through a feeding device.

[0004] When assembling large quantities of gas springs, belt conveyors are generally used to feed the outer sleeves. However, when the outer sleeves are sent to subsequent processing equipment, the belt conveyors often need to be installed at an angle due to the equipment conditions on site, and the shape of the outer sleeves makes it easy to slide on this inclined surface, affecting the transportation. At the same time, in the subsequent process, in order to meet the processing rules of the production equipment, the feeding device needs to ensure that the outer sleeves have the same delivery interval time, but the existing belt conveyors often cannot guarantee this.

[0005] The Chinese patent application number is: CN202022652159.5, and the patent document with the publication date of July 13, 2021 discloses a multi-station gas spring key power component automated assembly production device, including a frame, a turntable, a stepper motor, station one, station two, station three, station four, station five, and station six. The stepper motor is arranged on the frame, and the turntable is arranged on the top of the stepper motor, and the stepper motor can drive the turntable to rotate in a stepping manner. A plurality of slots for placing the piston rod are provided on the outer ring of the turntable, and a clamping cylinder for clamping the piston rod is provided at each slot on the turntable. The station one is used to put the guide sleeve on the piston rod, and the station two is used to put the oil seal sleeve on the piston rod.

[0006] The Chinese patent application number is: CN202010757305.2, and the patent document with the publication date of November 3, 2020 discloses a gas spring automatic assembly machine, which belongs to the field of gas spring automatic assembly technology, including a support platform, a rotating disk, a piston rod pressing mechanism, a piston rod feeding mechanism, and a sealing ring feeding mechanism. The piston rod pressing mechanism includes an assembly bench, a multi-degree-of-freedom manipulator, a piston rod grabbing manipulator assembly and a guide sleeve vibration feeding assembly; the piston rod grabbing manipulator assembly grabs the piston rod to the assembly bench, the guide sleeve vibration feeding assembly feeds the guide sleeve to the feeding position, the multi-degree-of-freedom manipulator places the guide sleeve on the assembly bench, and the pressing cylinder presses the guide sleeve into the piston rod; the piston rod feeding mechanism places the piston rod after the guide sleeve is assembled vertically on the rotating disk; the sealing ring feeding mechanism grabs the sealing ring and presses the sealing ring on the piston rod after the guide sleeve is assembled.

[0007] In the above two schemes, by setting up a turntable conveying device and setting a clamping structure on it, the problem that the outer sleeves need to have the same conveying interval time and the outer sleeves may slip can be solved. However, this turntable conveying device is difficult to achieve the demand of conveying a large number of outer sleeves at one time, so the processing efficiency of the gas spring will be affected.

[0033] Exemplary embodiments of the present invention are described in detail below. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope of the present invention. The more detailed description of the embodiments of the present invention below is not intended to limit the scope of the claimed present invention, but is merely for illustration and does not limit the description of the features and characteristics of the present invention, in order to propose the best way to perform the present invention, and is sufficient to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0034] Example 1

[0035] A gas spring outer sleeve and guide sleeve installation system is used in the assembly of the gas spring to realize the assembly of the outer sleeve and the guide sleeve and send the assembled outer sleeve to the next processing equipment. The specific structure and technical effect are described in detail below.

[0036] like Figure 1 As shown, the installation system includes an outer sleeve feeding device 1, a guide sleeve feeding device 2, a guide sleeve installation device 3 and an outer sleeve feeding device 4. The outer sleeve feeding device 1 transfers the outer sleeve to the guide sleeve installation station, the guide sleeve feeding device 2 conveys the guide sleeve to the guide sleeve installation device 3, the guide sleeve installation device 3 transfers the guide sleeve to the guide sleeve installation station and presses the guide sleeve into the end of the outer sleeve, and the outer sleeve feeding device 4 conveys the outer sleeve with the guide sleeve installed to the subsequent equipment.

[0037] In this embodiment, the outer sleeve feeding device 4 adopts a belt conveyor, and a plurality of outer sleeve receiving grooves 41 are evenly spaced along the conveying direction on its conveying surface. The inner cavity shape and size of the outer sleeve receiving grooves 41 match the shape and size of the outer sleeve.

[0038] After the outer sleeve is pressed into the guide sleeve, it can fall into the outer sleeve receiving groove 41. When the belt conveyor surface is in an inclined state, the outer sleeve will be blocked by the receiving groove and will not slide. In addition, since the intervals between adjacent outer sleeve receiving grooves 41 are equal and the feeding speed of the outer sleeve feeding device 4 remains unchanged, it can ensure that the outer sleeve is transported to the next device at a fixed interval speed to meet the subsequent processing requirements. At the same time, the belt conveyor can realize the feeding of a large number of outer sleeves at one time.

[0039] like Figure 2 and Figure 3 As shown, the outer sleeve feeding device 1 comprises an outer sleeve conveying device 11 and an outer sleeve positioning device 12 , and the end of the outer sleeve conveying device 11 is connected to the outer sleeve positioning device 12 .

[0040] The outer tube conveying device 11 includes a conveying frame 111 as an installation body and a belt conveyor 112 installed on the conveying frame 111, and the end of the belt conveyor 112 extends to the outer tube positioning device 12. The outer tube positioning device 12 includes a positioning platform 121, and the positioning platform 121 is equipped with an inner lifting block 122 and an outer lifting block 123 that are lifted and lowered by a block lifting device. In this embodiment, the block lifting device is installed on the positioning platform 121, and the synchronous lifting of the inner lifting block 122 and the outer lifting block 123 is achieved by a single cylinder. There is a gap between the inner lifting block 122 and the outer lifting block 123 to accommodate the outer tube, and the upper end surface heights of the inner lifting block 122 and the outer lifting block 123 gradually decrease along the conveying direction of the outer tube.

[0041] When the outer sleeve feeding device is working, the outer sleeve conveyed by the outer sleeve conveying device 11 will be blocked by the inner lifting block 122. The inner lifting block 122 and the outer lifting block 123 are controlled to descend synchronously, so that a single outer sleeve can slide along the inclined surface of the inner lifting block 122 toward the outer lifting block 123. At this time, the inner lifting block 122 and the outer lifting block 123 are raised synchronously, so that a single outer sleeve falls into the gap between the inner lifting block 122 and the outer lifting block 123, that is, the guide sleeve installation station, and the remaining outer sleeves are blocked by the inner lifting block 122 that is raised again, and then the guide sleeve is pressed on the outer sleeve through the guide sleeve installation device 3.

[0042] After the installation is completed, the inner lifting block 122 and the outer lifting block 123 are synchronously lowered again, so that the installed outer sleeve can enter the subsequent conveying equipment along the inclined surface of the outer lifting block 123 and be sent to the next processing equipment. At the same time, the new unprocessed outer sleeve falls into the upper end surface of the inner lifting block 122.

[0043] By repeating the above method, the inner lifting block 122 and the outer lifting block 123 are controlled to rise and fall synchronously in a cycle, so that the continuous conveying and positioning processing of the outer sleeve can be realized, thereby improving the installation efficiency of the gas spring.

[0044] In addition, a positioning plate 124 is also installed on the positioning platform 121. A strip groove perpendicular to the conveying direction of the outer sleeve is provided on the positioning platform 121. The strip groove is located on one side of the gap between the inner lifting block 122 and the outer lifting block 123. The positioning plate 124 is detachably fixed in the strip groove by bolts, and has a slot matching the end of the outer sleeve.

[0045] When the guide sleeve is pressed into the guide sleeve from the other end of the outer sleeve, the outer sleeve can be stuck in the slot to prevent the outer sleeve from shaking during the pressing process and affecting the pressing of the guide sleeve. The position of the positioning plate 124 can be adjusted through the strip groove on the positioning platform 121 to adapt to outer sleeves of different lengths.

[0046] A receiving plate whose upper end surface height gradually decreases along the conveying direction of the outer tube is installed between the outer tube conveying device 11 and the inner lifting block 122, which can smoothly realize the transition of the outer tube from the outer tube conveying device 11 to the guide sleeve installation station, ensuring the stability of the continuous conveying and positioning of the outer tube. At the same time, a blanking plate 125 is fixedly installed on the positioning platform 121, and the blanking plate 125 is located on the side of the outer lifting block 123 away from the outer tube conveying device 11, and its upper end surface height gradually decreases along the conveying direction of the outer tube, so that the outer tube after the guide sleeve is installed can smoothly fall into the outer tube receiving groove 41 of the outer tube feeding device 4 to prevent the outer tube from falling off.

[0047] In the outer tube conveying device 11, at least one pair of limit brackets 113 are symmetrically installed on both sides of the belt conveyor 112, and two pairs are installed in this embodiment. A horizontal limit rod 114 is installed between the limit brackets 23, which can screen out the outer tube with too large diameter to ensure the product accuracy of the gas spring. A pair of outer tube baffles 115 extending along the conveying direction of the outer tube are detachably fixedly installed on the limit rod 114, which can be adjusted according to the length of the outer tube to prevent the outer tube from tilting on the belt conveyor 112 and affecting its subsequent transportation to the guide sleeve installation station. In the specific installation structure of the limit bracket 113, a waist-shaped hole extending in the height direction is provided on the limit bracket 113, which is fixedly installed on the side of the belt conveyor 112 by bolts passing through the waist-shaped hole. Adjusting the installation position of the limit bracket 113 on the waist-shaped hole can realize the adjustment of the height of the limit bracket 113, and then realize the height adjustment of the limit rod 114 to adapt to outer tubes of different diameters.

[0048] like Figure 4 and Figure 5 As shown, the guide sleeve feeding device 2 includes a frame 21, a storage box 22 and a guide sleeve conveying device 23 installed on the frame 21. Among them, a fixed plate 24 is installed on one side of the storage box 22, an inner loading plate 25 is installed between the fixed plate 24 and the bottom plate of the storage box 22, and an outer loading plate 26 is installed between the fixed plate 24 and the guide sleeve conveying device 23. The inner loading plate 25 and the outer loading plate 26 are driven to rise and fall by the guide sleeve lifting device. At the same time, the height of the upper end surface of the fixed plate 24, the inner loading plate 25 and the outer loading plate 26 gradually decreases from the side of the storage box 22 to the side of the guide sleeve conveying device 23.

[0049] In this embodiment, in order to facilitate the installation of the fixing plate 24, a pair of connecting plates 210 are installed on one side of the material storage box 22 extending toward the guide sleeve conveying device 23, and the fixing plate 24 is fixedly installed between the pair of connecting plates 210. The connecting plates 210 are fixedly connected by reinforcing rods 211, thereby improving the structural strength of the connecting plates 210.

[0050] Specifically, the guide sleeve lifting device includes a lifting cylinder 27 and a lifting plate 28. One end of the lifting cylinder 27 is fixedly connected to the frame 21, and the other end is fixedly connected to the lifting plate 28, and the lifting plate 28 is fixedly connected to the inner loading plate 25 and the outer loading plate 26. By setting the lifting plate 28, a single cylinder can be used to achieve the lifting of two loading plates, thereby reducing the equipment cost. In order to ensure that the lifting direction of the loading plate is accurate and the loading is more stable, a guide rod 29 is installed on the frame 21 along the height direction, and the lifting plate 28 is provided with a guide hole matching the guide rod 29. In this embodiment, there are two guide rods 29, which are respectively installed on both sides of the lifting plate 28.

[0051] When the feeding device is working, the upper end surface of the inner feeding plate 25 drops to the height of the inner bottom surface of the storage box 22, and the guide sleeve of the storage box 22 slides onto the upper end surface of the inner feeding plate 25. Then the upper end surface of the inner feeding plate 25 rises to the height of the upper end surface of the fixed plate 24, and the guide sleeve on the inner feeding plate 25 moves to the upper end surface of the fixed plate 24 along the inclined surface and is blocked by the outer feeding plate 26. When the upper end surface of the outer feeding plate 26 drops to the height of the upper end surface of the fixed plate 24, the guide sleeve on the fixed plate 24 moves to the upper end surface of the outer feeding plate 26 along the inclined surface, and then the upper end surface of the outer feeding plate 26 rises to the height of the guide sleeve conveying device 23, and the guide sleeve 2 moves to the guide sleeve conveying device 23 along the inclined surface, completing the feeding of the guide sleeve.

[0052] Through this structure, a large number of guide sleeves can be stored at one time, and there is no need to frequently add guide sleeves, which reduces labor costs, and the equipment structure is simple and low in cost. In particular, the two-stage loading method of the inner loading plate 25 and the outer loading plate 26 reduces the lifting stroke of the guide sleeve lifting device compared to the one-stage lifting and loading method, reduces equipment costs, and the lifting process is more stable.

[0053] In this embodiment, in order to enable the guide sleeve in the storage box 22 to smoothly slide onto the inner loading plate 25 and be lifted up, the height of the inner bottom surface of the storage box 22 is gradually reduced from the storage box 22 side to the guide sleeve conveying device 23 side. A guide plate 212 is fixedly installed above the connecting plate 210, and the guide plate 212 is located between the guide sleeve conveying device 23 and the outer loading plate 26. The height of the guide plate 212 is gradually reduced from the storage box 22 side to the guide sleeve conveying device 23 side, so that the guide sleeve can be accurately transferred from the outer loading plate 26 to the guide sleeve conveying device 23. It should be noted that in order to prevent the guide sleeve from falling off the upper end surface of the outer loading plate 26, a baffle is provided on the outer side of the outer loading plate 26, and the baffle is fixedly installed between a pair of connecting plates 210.

[0054] In this embodiment, the guide sleeve conveying device 23 is a belt conveyor. A limit plate 213 is installed above the guide sleeve conveying device 23 away from the storage box 22, which can detect the size of the guide sleeve and block the unqualified guide sleeve with a larger size to avoid affecting subsequent processing.

[0055] The guide sleeve installation device 3 can use existing transfer equipment and pushing equipment, such as transferring the guide sleeve to the installation station of the guide sleeve by a manipulator, and then pushing the guide sleeve by a cylinder or oil cylinder located at the installation station to press the guide sleeve into the outer sleeve to complete the installation.

[0056] In summary, the installation system of the gas spring outer sleeve and the guide sleeve of the present embodiment can smoothly complete the installation of the guide sleeve by pressing it into the outer sleeve, and has high installation efficiency.
