Description

Technical Field

[0001] The utility model belongs to the technical field of gas springs, and more specifically relates to a guide 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. At present, in order to ensure the assembly efficiency and assembly accuracy of the gas spring, the various components of the gas spring are generally transported and loaded and assembled through automated equipment. Therefore, the loading conditions of the components often determine the production conditions of the gas spring. However, when the existing loading equipment is used to load the guide sleeve, the actual use effect is not ideal.

[0004] For example, the patent document with Chinese patent application number: CN202120941769.9 and publication date: November 5, 2021, discloses a sleeve feeding mechanism, including a sleeve handling assembly, the sleeve handling assembly including a first rotating motor, a horizontal track and a swing arm, one end of the swing arm is mounted on the output shaft of the first rotating motor, a lifting rod is hinged on the other end of the swing arm, a mounting plate is slidably provided on the horizontal track, a guide block is vertically provided on the upper edge of the mounting plate, the lifting rod is slidably installed on the guide block, and a clamping claw assembly is installed on the lifting rod. The first rotating motor controls the rotation of the swing arm, driving the lifting rod on the swing arm to swing up and down. Under the action of the lifting rod, the mounting plate drives the lifting rod to move horizontally along the horizontal track, and at the same time slides up and down along the guide block, forming an up and down undulating form of handling and feeding.

[0005] Another example is the Chinese patent application number: CN202321283804.8, the publication date: September 12, 2023, which discloses a loading and lifting mechanism, including a frame, a conveying mechanism for conveying a sleeve is installed on the frame, a receiving basket for receiving the sleeve output by the conveying mechanism is hinged on the frame, and a lifting drive mechanism is also provided on the frame, the lifting drive mechanism is connected to the bottom of the receiving basket and can drive the receiving basket so that its end near the feeding end is higher than the other end; a guide plate is provided on the side wall of the receiving frame near the discharge port, a buffer is provided between the guide plate and the side wall of the receiving frame, and the upper end of the guide plate has an inclined surface for the sleeve to slide into the receiving basket. By providing a conveying mechanism and other structures, the sleeve is automatically transported to the machine tool.

[0006] Although the feeding equipment of the above two schemes can realize the automatic feeding of the gas spring guide sleeve, in actual use, it is necessary to place the guide sleeve on the conveying device through external equipment such as a relatively complex and precise manipulator or manually, which has the problem of high equipment cost or waste of human resources, and it is impossible to store multiple guide sleeves at a time, and the guide sleeves need to be transported continuously, which is time-consuming and laborious. If external equipment such as a relatively complex and precise manipulator or manual labor is not used, the feeding accuracy of the guide sleeve is difficult to be guaranteed. Therefore, a guide sleeve feeding equipment with better use effect is needed. Summary of the invention

[0031] 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.

[0032] Example 1

[0033] A guide sleeve feeding device for a gas spring is used in the assembly operation of the gas spring to realize the feeding and transportation of the guide sleeve. The specific structure and technical effect thereof are described in detail below.

[0034] like Figure 1 and Figure 2 As shown, the feeding equipment mainly includes a frame 1, a material storage box 2 and a guide sleeve conveying device 3 installed on the frame 1. Among them, a fixed plate 4 is installed on one side of the material storage box 2, an inner feeding plate 5 is installed between the fixed plate 4 and the bottom plate of the material storage box 2, and an outer feeding plate 6 is installed between the fixed plate 4 and the guide sleeve conveying device 3. The inner feeding plate 5 and the outer feeding plate 6 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 4, the inner feeding plate 5 and the outer feeding plate 6 gradually decreases from the side of the material storage box 2 to the side of the guide sleeve conveying device 3.

[0035] In this embodiment, in order to facilitate the installation of the fixed plate 4, a pair of connecting plates 10 are installed on one side of the storage box 2 extending toward the guide sleeve conveying device 3, and the fixed plate 4 is fixedly installed between the pair of connecting plates 10. The connecting plates 10 are fixedly connected by reinforcing rods 11, which improves the structural strength of the connecting plates 10.

[0036] Specifically, the guide sleeve lifting device includes a lifting cylinder 7 and a lifting plate 8. One end of the lifting cylinder 7 is fixedly connected to the frame 1, and the other end is fixedly connected to the lifting plate 8, and the lifting plate 8 is fixedly connected to the inner loading plate 5 and the outer loading plate 6. By setting the lifting plate 8, 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 9 is installed on the frame 1 along the height direction, and the lifting plate 8 is provided with a guide hole matching the guide rod 9. In this embodiment, there are two guide rods 9, which are respectively installed on both sides of the lifting plate 8.

[0037] When the feeding device is working, the upper end surface of the inner feeding plate 5 drops to the height of the inner bottom surface of the storage box 2, and the guide sleeve of the storage box 2 slides to the upper end surface of the inner feeding plate 5. Then the upper end surface of the inner feeding plate 5 rises to the height of the upper end surface of the fixed plate 4, and the guide sleeve on the inner feeding plate 5 moves to the upper end surface of the fixed plate 4 along the inclined surface and is blocked by the outer feeding plate 6. When the upper end surface of the outer feeding plate 6 drops to the height of the upper end surface of the fixed plate 4, the guide sleeve on the fixed plate 4 moves to the upper end surface of the outer feeding plate 6 along the inclined surface, and then the upper end surface of the outer feeding plate 6 rises to the height of the guide sleeve conveying device 3, and the guide sleeve 2 moves to the guide sleeve conveying device 3 along the inclined surface, completing the feeding of the guide sleeve.

[0038] 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 5 and the outer loading plate 6 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.

[0039] In this embodiment, in order to enable the guide sleeve in the storage box 2 to smoothly slide onto the inner loading plate 5 and be lifted up, the height of the inner bottom surface of the storage box 2 is gradually reduced from the storage box 2 side to the guide sleeve conveying device 3 side. A guide plate 12 is fixedly installed above the connecting plate 10, and the guide plate 12 is located between the guide sleeve conveying device 3 and the outer loading plate 6. Its height is gradually reduced from the storage box 2 side to the guide sleeve conveying device 3 side, so that the guide sleeve can be accurately transferred from the outer loading plate 6 to the guide sleeve conveying device 3. It should be noted that in order to prevent the guide sleeve from falling off from the upper end surface of the outer loading plate 6, a baffle is provided on the outer side of the outer loading plate 6, and the baffle is fixedly installed between a pair of connecting plates 10.

[0040] In this embodiment, the guide sleeve conveying device 3 is a belt conveyor. A limit plate 13 is installed above the guide sleeve conveying device 3 away from the storage box 2, which can detect the size of the guide sleeve and block the unqualified guide sleeve with a larger size to avoid affecting the subsequent processing.

[0041] In summary, the guide sleeve feeding equipment for a gas spring of the present embodiment can store a large number of guide sleeves at one time without the need to frequently add guide sleeves, thereby ensuring the feeding efficiency while reducing equipment and labor costs.
