Description

Technical Field

[0001] The utility model belongs to the technical field of gas springs, and more specifically relates to an outer sleeve feeding device for 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. When installing the gas spring guide sleeve, the outer sleeve of the gas spring is moved to the installation station of the guide sleeve through the conveying device, and then the guide sleeve is pressed into the outer sleeve to achieve the installation of the guide sleeve. In this process, how to realize the transformation of the outer sleeve from continuous movement during the conveying process to precise positioning and immobility at the installation station is an important factor in improving the installation efficiency and installation accuracy of the guide sleeve.

[0004] 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.

[0005] 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.

[0006] The above schemes can all realize the press-fit installation of the guide sleeve on the piston rod. Although they can also be used to press the guide tube into the outer sleeve for installation, both of them use a method of using a robot to clamp the piston rod as the installation subject to the work station or put it into a turntable slot. When this transportation method is used for the outer sleeve, the installation of the outer sleeve requires a lot of time. Therefore, it is difficult to ensure the installation speed of a large number of outer sleeves and guide sleeves, and the installation efficiency is not high. Summary of the 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.

[0032] Example 1

[0033] A gas spring outer sleeve feeding device is used to realize the feeding and positioning of the outer sleeve during the installation process of the gas spring. The specific structure and technical effect thereof are described in detail below.

[0034] like Figure 1 and Figure 2 As shown, the outer sleeve feeding device includes an outer sleeve conveying device 1 and an outer sleeve positioning device 2, and the end of the outer sleeve conveying device 1 is connected to the outer sleeve positioning device 2.

[0035] The outer tube conveying device 1 includes a conveying frame 11 as an installation body and a belt conveyor 12 installed on the conveying frame 11, and the end of the belt conveyor 12 extends to the outer tube positioning device 2. The outer tube positioning device 2 includes a positioning platform 21, and the positioning platform 21 is equipped with an inner lifting block 22 and an outer lifting block 23 that are lifted and lowered by a block lifting device. In this embodiment, the block lifting device is installed on the positioning platform 21, and the synchronous lifting of the inner lifting block 22 and the outer lifting block 23 is achieved by a single cylinder. There is a gap between the inner lifting block 22 and the outer lifting block 23 to accommodate the outer tube, and the upper end surface heights of the inner lifting block 22 and the outer lifting block 23 gradually decrease along the conveying direction of the outer tube.

[0036] When the outer sleeve feeding device is working, the outer sleeve conveyed by the outer sleeve conveying device 1 will be blocked by the inner lifting block 22. The inner lifting block 22 and the outer lifting block 23 are controlled to descend synchronously, so that a single outer sleeve can slide down along the inclined surface of the inner lifting block 22 toward the outer lifting block 23. At this time, the inner lifting block 22 and the outer lifting block 23 are raised synchronously, so that a single outer sleeve falls into the gap between the inner lifting block 22 and the outer lifting block 23, that is, the guide sleeve installation station, and the remaining outer sleeves are blocked by the inner lifting block 22 that rises again, and then the guide sleeve is pressed into the outer sleeve through the external device.

[0037] After the installation is completed, the inner lifting block 22 and the outer lifting block 23 are lowered synchronously again, so that the installed outer sleeve can enter the subsequent conveying equipment along the inclined surface of the outer lifting block 23 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 22.

[0038] By repeating the above method, the inner lifting block 22 and the outer lifting block 23 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.

[0039] In addition, a positioning plate 24 is also installed on the positioning platform 21. A strip groove perpendicular to the conveying direction of the outer sleeve is provided on the positioning platform 21. The strip groove is located on one side of the gap between the inner lifting block 22 and the outer lifting block 23. The positioning plate 24 is detachably fixed in the strip groove by bolts, and has a slot matching the end of the outer sleeve.

[0040] 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 24 can be adjusted through the strip groove on the positioning platform 21 to adapt to outer sleeves of different lengths.

[0041] 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 1 and the inner lifting block 22, which can smoothly realize the transition of the outer tube from the outer tube conveying device 1 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 25 is fixedly installed on the positioning platform 21, and the blanking plate 25 is located on the side of the outer lifting block 23 away from the outer tube conveying device 1. The height of its upper end surface 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 subsequent conveying equipment to prevent the outer tube from falling off.

[0042] In the outer tube conveying device 1, at least one pair of limit brackets 13 are symmetrically installed on both sides of the belt conveyor 12, and two pairs are installed in this embodiment. A horizontal limit rod 14 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 15 extending along the conveying direction of the outer tube are detachably fixedly installed on the limit rod 14, which can be adjusted according to the length of the outer tube to prevent the outer tube from tilting on the belt conveyor 12 and affecting its subsequent transportation to the guide sleeve installation station. In the specific installation structure of the limit bracket 13, a waist-shaped hole extending in the height direction is provided on the limit bracket 13, which is fixedly installed on the side of the belt conveyor 12 by bolts passing through the waist-shaped hole. Adjusting the installation position of the limit bracket 13 on the waist-shaped hole can realize the adjustment of the height of the limit bracket 13, and then realize the height adjustment of the limit rod 14 to adapt to outer tubes of different diameters.

[0043] In summary, the outer sleeve feeding device of a gas spring in this embodiment can realize the continuous conveying and positioning of the outer sleeve of the gas spring, facilitate the rapid press-in installation of the guide sleeve, and effectively improve the installation efficiency.
