Description

Technical Field

[0001] This utility model relates to the field of sealing assembly technology, and in particular to a high-precision sealing assembly device for a hydraulic cylinder. Background Technology

[0002] Hydraulic cylinder sealing components often employ a ring-shaped structure to ensure that high-pressure liquid or gas inside the cylinder does not leak, maintains stable internal pressure, and guarantees normal operation. However, in actual assembly, numerous challenges arise. Currently, traditional assembly methods still have significant drawbacks. Because the sealing component is ring-shaped, it is difficult to achieve precise positive positioning when manually placing it directly into the cylinder. During operation, operators rely solely on visual observation and manual experience to place the sealing component, which is highly susceptible to human error and easily leads to displacement of the sealing component within the cylinder. Once the sealing component shifts, high-pressure liquid or gas may leak from the gap between the sealing component and the inner wall of the cylinder during operation. This not only reduces the working efficiency of the hydraulic cylinder but may also cause equipment failure and pose serious safety hazards.

[0003] To address the aforementioned issues, we propose a high-precision sealing assembly device for hydraulic cylinders. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision sealing assembly device for hydraulic cylinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision sealing assembly device for hydraulic cylinders includes a hydraulic cylinder assembly platform, with a sealing element clamping assembly positioned above the assembly platform. The sealing element clamping assembly includes an electric telescopic rod, with several lateral connecting rods fixedly mounted on its side wall. Several shaft seats are fixedly mounted on the output end side wall of the electric telescopic rod. A rotating groove is formed at the lower end of each lateral connecting rod. A rotating rod is rotatably mounted inside each shaft seat. A sleeve is slidably fitted onto the outer wall of the rotating rod, and the sleeve is rotatably mounted inside the rotating groove. An installation block is fixedly mounted at the end of the rotating rod. A support is fixedly mounted on the installation block, and a fixed shaft is rotatably mounted on the support. An external clamping piece is fixedly connected to the fixed shaft.

[0007] Furthermore, the positions of the lateral connecting rods and the bearings are in one-to-one correspondence, and the lateral connecting rods and the bearings are all equiangularly distributed around the circumference of the electric telescopic rod axis.

[0008] Furthermore, a disc base is fixedly installed at the output end of the electric telescopic rod, and an LED light group is fixedly installed on the disc base.

[0009] Furthermore, a support frame is fixedly installed on the upper side of the hydraulic cylinder assembly platform, an electric lifting rod is fixedly installed at the bottom of the support frame, an installation plate is fixedly installed on the lower side of the output end of the electric lifting rod, and the installation plate is fixedly connected to the upper end of the electric telescopic rod.

[0010] Furthermore, the outer wall of the electric telescopic rod is fixedly connected to the mounting plate with several reinforcing ribs.

[0011] Furthermore, a positioning groove is provided at the center of the upper side of the hydraulic cylinder assembly platform, and a cross positioning guideline is provided inside the positioning groove. The center of the positioning groove coincides with the center line of the electric telescopic rod.

[0012] Furthermore, a controller is fixedly installed on the hydraulic cylinder assembly platform.

[0013] Compared with related technologies, the high-precision sealing assembly device for hydraulic cylinders proposed in this utility model has the following beneficial effects:

[0014] In this utility model, a high-precision sealing assembly device for a hydraulic cylinder is described. Through a set of sealing clamping components, the output end of an electric telescopic rod drives a rotating rod to rotate, thereby changing the outward expansion range of several rotating rods. This adjusts the outward expansion range of the outermost clamping plates, enabling the device to clamp sealing components of different inner diameters. Since the outer clamping plates are evenly distributed along the axis of the electric telescopic rod, the sealing component clamped by these plates is horizontal, with its center corresponding to the axis of the electric telescopic rod. This drives the sealing clamping assembly downwards, allowing the clamped sealing component to enter the hydraulic cylinder horizontally for assembly. This avoids deviations caused by manual positioning by the operator, enhancing practicality. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figure 1-5 A high-precision sealing assembly device for hydraulic cylinders includes a hydraulic cylinder assembly platform 1, with a sealing component clamping assembly 6 positioned above the assembly platform 1. The sealing component clamping assembly 6 includes an electric telescopic rod 61, with several lateral connecting rods 63 fixedly installed on the side wall of the electric telescopic rod 61, and several shaft seats 65 fixedly installed on the side wall of the output end of the electric telescopic rod 61. A rotating groove 64 is provided at the lower end of the lateral connecting rods 63, and a rotating rod 66 is rotatably installed inside the shaft seat 65. A sleeve 69 is slidably sleeved on the outer wall of the rotating rod 66, and the sleeve 69 is rotatably installed inside the rotating groove 64. An installation block 610 is fixedly installed at the end of the rotating rod 66, a support 611 is fixedly installed on the installation block 610, a fixed shaft 612 is rotatably installed on the support 611, and an external clamping piece 613 is fixedly connected to the fixed shaft 612.

[0023] With the above-described configuration, when the electric telescopic rod 61 extends or retracts, its output end will drive the rotating rod 66 to rotate inside the bearing seat 65, thereby causing the rotating rod 66 to slide relative to the sleeve 69, which changes the relative horizontal distance of the outer end of the rotating rod 66, and thus changes the clamping range of the outer clamping piece 613 on the end of the rotating rod 66, for clamping work on seals with different inner diameters.

[0024] In this method, the positions of several lateral connecting rods 63 and several bearing seats 65 correspond one-to-one, and the several lateral connecting rods 63 and several bearing seats 65 are all distributed at equal angles around the circumference of the axis of the electric telescopic rod 61.

[0025] By setting it in the above manner, the distribution points of the outer ends of several rotating rods 66 are evenly distributed along the axis of the electric telescopic rod 61, which further makes the clamping point distribution of the outer clamping plate 613 uniform when it clamps the seal, thus improving the stability of the seal clamping.

[0026] In this method, a disc base 67 is fixedly installed at the output end of the electric telescopic rod 61, and an LED light group 68 is fixedly installed on the disc base 67.

[0027] With the above-described configuration, the LED light group 68 is designed to facilitate the operator's observation of the installation space inside the hydraulic cylinder.

[0028] In this method, a support frame 3 is fixedly installed on the upper side of the hydraulic cylinder assembly table 1, an electric lifting rod 4 is fixedly installed at the bottom of the support frame 3, an installation plate 5 is fixedly installed on the lower side of the output end of the electric lifting rod 4, and the installation plate 5 is fixedly connected to the upper end of the electric telescopic rod 61.

[0029] With the above-mentioned setup, starting the electric lifting rod 4 can drive the mounting plate 5 to move up and down, thereby adjusting the height of the entire sealing component clamping assembly 6, so that the sealing component clamped by the sealing component clamping assembly 6 can be driven into the inner side of the hydraulic cylinder. In addition, the controller 2 can precisely control the descent distance, thereby ensuring that the clamped sealing component is accurately positioned in the vertical position.

[0030] In this method, a number of reinforcing connecting ribs 62 are fixedly connected between the outer wall of the electric telescopic rod 61 and the mounting plate 5.

[0031] The above-mentioned configuration improves the connection strength between the electric telescopic rod 61 and the mounting plate 5.

[0032] In this method, a positioning groove 7 is provided at the center of the upper side of the hydraulic cylinder assembly table 1, and a cross positioning guideline 8 is provided inside the positioning groove 7. The center of the positioning groove 7 coincides with the center line of the electric telescopic rod 61.

[0033] By setting it up in the above manner, the hydraulic cylinder to be assembled is placed in the center of the positioning groove 7. At this time, the axis of the hydraulic cylinder coincides with the axis of the electric telescopic rod 61 and coincides with the clamping center of the entire sealing clamping assembly 6. Thus, the sealing component clamped by the sealing clamping assembly 6 can fall directly into the hydraulic cylinder, which facilitates accurate positioning during the assembly process.

[0034] In this method, a controller 2 is fixedly installed on the hydraulic cylinder assembly table 1.

[0035] Through the above-described configuration, controller 2 is used to control the operating status of each electrical component in this invention.

[0036] The working principle of the high-precision sealing assembly device for hydraulic cylinders provided by this utility model is as follows:

[0037] In use, the hydraulic cylinder of the seal to be assembled is placed in the positioning groove 7 of the hydraulic cylinder assembly table 1. The position of the hydraulic cylinder is precisely adjusted using the crosshair 8 so that the axis of the hydraulic cylinder is completely aligned with the center of the positioning groove 7 and the axis of the electric telescopic rod 61. According to the inner diameter of the seal to be assembled, the controller 2 is activated to start the electric telescopic rod 61. The output end of the electric telescopic rod 61 extends or retracts, causing the rotating rod 66 to slide relative to the sleeve 69. This causes the outer clamping plate 613 at the end of the rotating rod 66 to expand or retract, adjusting it to a suitable clamping range. The seal is then placed between several outer clamping plates 613. The electric telescopic rod 61 is further fine-tuned to ensure that the outer clamping plates 613 are properly aligned. 13. The seal is clamped evenly and firmly, ensuring that it is horizontal and that its center corresponds to the axis of the electric telescopic rod 61. The operator controls the controller 2 to start the electric lifting rod 4. The electric lifting rod 4 drives the mounting plate 5 and the entire seal clamping assembly 6 to descend slowly. The LED light group 68 illuminates the inside of the hydraulic cylinder. The operator observes and ensures that the seal enters the hydraulic cylinder horizontally and positively along the axis of the hydraulic cylinder. When the seal reaches the predetermined assembly position, the operator controls the controller 2 to stop the electric lifting rod 4 and proceed with the assembly work. Then, the operator controls the electric telescopic rod 61 to retract, causing the outer clamping plate 613 to release the seal, thus completing the assembly of the seal.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
