Technical Field

[0001] This utility model relates to the field of hydraulic cylinder assembly technology, and in particular to an automatic assembly table for hydraulic cylinder assemblies. Background Technology

[0002] The hydraulic cylinder assembly automatic assembly station is a highly integrated and intelligent automated equipment. Through a precise mechanical structure, sensor system and control system, it can automatically feed, accurately position and efficiently assemble hydraulic cylinder barrels, pistons, seals and other parts. It realizes the fully automated operation from parts input to finished hydraulic cylinder assembly output, which can effectively improve assembly efficiency and quality stability, and reduce labor costs and assembly errors.

[0003] In the assembly process of hydraulic cylinders, the initial assembly of the sealing components and piston components must be completed beforehand, and then they are transferred to an automated assembly table for final assembly. However, during the hydraulic cylinder assembly stage, it often happens that the components are not aligned vertically, which leads to assembly deviations. This results in the assembly rod and assembly hole not being accurately aligned, ultimately adversely affecting assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where components are often not aligned on the same vertical line during the assembly stage of hydraulic cylinder assemblies, which leads to assembly deviations. Therefore, this invention proposes an automatic assembly table for hydraulic cylinder assemblies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic assembly table for hydraulic cylinder assemblies, comprising an assembly platform, a first guide rail fixedly installed in the middle of the assembly platform, a cylinder body positioning assembly and a piston rod positioning and pushing assembly respectively provided at both ends of the first guide rail, a sealing cover plate positioning assembly slidably connected to the upper end of the first guide rail, a first electric push rod respectively provided on both sides of the cylinder body positioning assembly, the driving ends of the two sets of first electric push rods fixedly connected to both sides of the sealing cover plate positioning assembly, and the cylinder body positioning assembly, the piston rod positioning and pushing assembly and the sealing cover plate positioning assembly located on the same horizontal line.

[0006] Preferably, the cylinder positioning assembly includes a cylinder support groove and a cylinder bottom positioning baffle.

[0007] Preferably, the piston rod positioning and pushing assembly includes a second adjusting base plate, a piston rod support groove, and two sets of second electric push rods.

[0008] Preferably, the sealing cover positioning assembly includes a sealing cover support groove and a first adjusting base plate. The sealing cover support groove is fixedly installed on one side of the first adjusting base plate, and a first slider is fixedly connected to each of the four corners of the other side of the first adjusting base plate. The first slider is slidably connected to the outside of the first guide rail.

[0009] Preferably, a second guide rail is fixedly installed on one side of the first adjusting base plate.

[0010] Preferably, a second slider is fixedly installed at each of the four corners on the other side of the second adjusting base plate, and the second slider is slidably connected to the outside of the second guide rail.

[0011] Preferably, a positioning side plate is fixedly connected to one side of the sealing cover support groove, and a positioning rod is movably inserted through the interior of the positioning side plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting the cylinder positioning assembly, piston rod positioning and pushing assembly and sealing cover plate positioning assembly on the same horizontal line, the components of the piston cylinder will not deviate during the automatic assembly process, thereby improving the assembly accuracy and efficiency.

[0014] 2. In this utility model, by extending one end of the positioning rod into one side of the sealing cover plate, the sealing cover plate is positioned to prevent it from shifting during assembly. This ensures that the sealing cover plate always maintains the preset installation posture in subsequent assembly stages, effectively avoiding the problem of loose sealing surface due to positional shift. This provides a reliable guarantee for the sealing performance of the hydraulic cylinder and reduces the risk of oil leakage and other malfunctions caused by seal failure.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-4 As shown, this utility model provides an automatic assembly table for a hydraulic cylinder assembly, including an assembly platform 1. A first guide rail 11 is fixedly installed in the middle of the assembly platform 1. A cylinder positioning assembly 2 and a piston rod positioning and pushing assembly 3 are respectively provided at both ends of the first guide rail 11. A sealing cover plate positioning assembly 4 is slidably connected to the upper end of the first guide rail 11. A first electric push rod 5 is provided on both sides of the cylinder positioning assembly 2. The driving ends of the two sets of first electric push rods 5 are fixedly connected to both sides of the sealing cover plate positioning assembly 4. The cylinder positioning assembly 2, the piston rod positioning and pushing assembly 3 and the sealing cover plate positioning assembly 4 are located on the same horizontal line. The cylinder positioning assembly 2 includes a cylinder support groove 21 and a cylinder bottom positioning baffle 22. The piston rod positioning and pushing assembly 3 includes a second adjusting base plate 31, a piston rod support groove 32 and two sets of second electric push rods 33. The driving ends of the two sets of second electric push rods 33 are respectively fixedly connected to both sides of the second adjusting base plate 31. The piston rod support groove 32 is fixedly installed on one side of the second adjusting base plate 31.

[0023] The specific setup and function of this embodiment are described below. The cylinder body is placed inside the cylinder body positioning assembly 2, so that the positioning baffle 22 at the bottom of the cylinder body abuts against one end of the cylinder body. At the same time, the cylinder body support groove 21 provides stable support to the outside of the cylinder body. Then, the sealing cover is placed inside the sealing cover positioning assembly 4 and the sealing cover is initially assembled. The piston rod is placed inside the piston rod positioning and pushing assembly 3 and initially assembled. After assembly, the second electric push rod 33 pushes the piston rod to slide towards one side of the sealing cover positioning assembly 4, so that the piston rod extends into the interior of the sealing cover. Then, the first electric push rod 5 drives the sealing cover positioning assembly 4 to move towards the cylinder body, thereby realizing the automatic assembly of the hydraulic cylinder. By setting the cylinder body positioning assembly 2, the piston rod positioning and pushing assembly 3 and the sealing cover positioning assembly 4 on the same horizontal line, the components of the piston cylinder will not deviate during the automatic assembly process, improving the assembly accuracy and efficiency.

[0024] Example 2: Figures 1-4 As shown, the automatic assembly table for the hydraulic cylinder assembly in this utility model includes an assembly platform 1. A first guide rail 11 is fixedly installed in the middle of the assembly platform 1. A cylinder body positioning assembly 2 and a piston rod positioning and pushing assembly 3 are respectively provided at both ends of the first guide rail 11. A sealing cover plate positioning assembly 4 is slidably connected to the upper end of the first guide rail 11. A first electric push rod 5 is provided on both sides of the cylinder body positioning assembly 2. The driving ends of the two sets of first electric push rods 5 are fixedly connected to both sides of the sealing cover plate positioning assembly 4. The cylinder body positioning assembly 2, the piston rod positioning and pushing assembly 3, and the sealing cover plate positioning assembly 4 are located on the same horizontal line. The sealing cover plate positioning assembly 4 includes a sealing cover. The plate support groove 41 and the first adjusting base plate 42 are fixedly installed on one side of the first adjusting base plate 42. The four corners of the other side of the first adjusting base plate 42 are respectively fixedly connected to the first slider 43. The first slider 43 is slidably connected to the outside of the first guide rail 11. The second guide rail 421 is fixedly installed on one side of the first adjusting base plate 42. The four corners of the other side of the second adjusting base plate 31 are respectively fixedly installed to the second slider 311. The second slider 311 is slidably connected to the outside of the second guide rail 421. The positioning side plate 44 is fixedly connected to one side of the sealing cover plate support groove 41. The positioning rod 441 is movably passed through the interior of the positioning side plate 44.

[0025] The overall effect of this embodiment is that after the sealing cover plate support groove 41 provides support for the sealing cover plate, one end of the positioning rod 441 is inserted into one side of the sealing cover plate to position the sealing cover plate, preventing the sealing cover plate from shifting during assembly. This ensures that the sealing cover plate always maintains the preset installation posture in subsequent assembly stages, effectively avoiding the problem of loose sealing surface due to positional shift, providing reliable protection for the sealing performance of the hydraulic cylinder, and reducing the risk of failures such as oil leakage caused by seal failure.

[0026] The method of use and working principle of this device are as follows: The cylinder body is placed inside the cylinder body positioning assembly 2, so that the positioning baffle 22 at the bottom of the cylinder body abuts against one end of the cylinder body. At the same time, the cylinder body support groove 21 provides stable support to the outside of the cylinder body. Then, the sealing cover is placed inside the sealing cover positioning assembly 4 and the sealing cover is initially assembled. After the sealing cover is supported by the sealing cover support groove 41, one end of the positioning rod 441 is inserted into one side of the sealing cover to position the sealing cover. The piston rod is placed inside the piston rod positioning and pushing assembly 3 for initial assembly. After assembly, the second electric push rod 33 pushes the piston rod to slide towards one side of the sealing cover positioning assembly 4, so that the piston rod extends into the interior of the sealing cover. Then, the first electric push rod 5 drives the sealing cover positioning assembly 4 to move towards the cylinder body, thereby realizing the automatic assembly of the hydraulic cylinder.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
