Description

Technical Field

[0001] This utility model relates to the field of hydraulic joint assembly, and in particular to a straight-core hydraulic joint assembly device. Background Technology

[0002] A straight-core hydraulic connector typically consists of several parts, including the connector body, sealing mechanism, connecting threads, and locking mechanism. Straight-core hydraulic connectors usually have a relatively simple and direct internal flow channel design; the flow channel is generally straight, allowing for relatively smooth flow of hydraulic oil within the connector with low resistance.

[0003] Because straight-core hydraulic connectors are often designed to be more compact than standard hydraulic connectors, their overall size is relatively smaller. During assembly, the sealing groove may be located inside the hydraulic connector (see instruction manual). Figure 5 As shown in the figure, the installation of the sealing ring is therefore more difficult. Based on this, in order to quickly and conveniently install the sealing ring of the hydraulic connector, the applicant proposes a straight-core hydraulic connector assembly device. Utility Model Content

[0004] To address the technical problem of quickly installing sealing rings during hydraulic joint assembly, this utility model provides a straight-core hydraulic joint assembly device.

[0005] This utility model is achieved by the following technical solution: a straight-core hydraulic connector assembly device, including a mounting frame, on which are provided:

[0006] A clamp plate is movably mounted on the mounting bracket and is used to fix the straight-core hydraulic connector.

[0007] A sleeve assembly is movably mounted on the mounting bracket. One end of the sleeve assembly can be inserted into the interior of the straight-core hydraulic connector. The sleeve assembly includes an outer sleeve and an inner connecting rod, with one end of the inner connecting rod movably sleeved inside the outer sleeve.

[0008] A push rod, which is fixedly connected to one end of the inner connecting rod, and one end of the push rod can extend out of the outer sleeve;

[0009] A drive mechanism is installed inside the mounting bracket and is used to drive the sleeve assembly to move up and down.

[0010] The above technical solution first uses a clamp to fix the hydraulic connector, keeping it vertically upward. Then, the sealing ring is fitted onto the outside of the sleeve assembly. A drive mechanism moves the sleeve assembly and sealing ring together into the hydraulic connector, while a push rod pushes the sealing ring into the sealing groove of the hydraulic connector. This completes the installation of the sealing ring.

[0011] As a further improvement to the above solution, a first spring is sleeved on the outer side of the inner connecting rod, and a push rod is fixedly connected to the bottom of the inner connecting rod, while the upper end of the inner connecting rod is connected to the drive mechanism.

[0012] As a further improvement to the above solution, a limiting ring is fixedly connected to the outer side of the outer sleeve, and a second spring is sleeved on the outer side of the outer sleeve. A support frame is also fixedly installed on the inner side of the mounting frame. The outer sleeve is movably installed on the support frame and can move up and down along the support frame.

[0013] As a further improvement to the above solution, a connector is fixedly connected to the bottom of the outer sleeve, and a push hole is opened at the bottom of the connector, through which the lower end of the push rod can extend out of the connector.

[0014] With the above technical solution, when the lower end of the push rod extends out of the connector through the push hole, it will contact the sealing ring. If the push rod continues to move, it will push the sealing ring off the connector. If the end of the connector is inside the hydraulic joint at this time, the push rod will push the sealing ring into the sealing groove of the hydraulic joint.

[0015] As a further improvement to the above solution, the clamping plate includes a fixed clamping plate and a movable clamping plate. First, the fixed clamping plate is fixedly connected to the mounting frame, and the mounting frame is also provided with a limiting groove. The bottom of the movable clamping plate is fixedly connected to a limiting slider, which is slidably installed in the limiting groove. At the same time, a spring rod is fixedly connected to the side of the movable clamping plate facing the fixed clamping plate, and the other end of the spring rod passes through the fixed rod.

[0016] The above technical solution features V-shaped latches on opposite sides of the movable and fixed clamps for securing the hydraulic connector. The user can simply pull the movable clamp to insert the hydraulic connector into the latches, and then release the movable clamp. The movable clamp, under the action of a spring, will automatically clamp the hydraulic connector, securing it in place.

[0017] As a further improvement to the above solution, the drive mechanism includes a hydraulic telescopic rod and a lifting link. The hydraulic telescopic rod is fixedly installed on the outside of the mounting frame, and the lifting link is disposed on the inside of the mounting frame. The lifting link and the inner link are fixedly connected. In addition, a connecting block is included, and the two sides of the connecting block are fixedly connected to the hydraulic telescopic rod and the lifting link, respectively.

[0018] As a further improvement to the above solution, an elongated through hole is provided on the mounting frame at the position corresponding to the connecting block, and the connecting block passes through the through hole. At the same time, a retaining plate is provided on the side wall of the mounting frame at the position corresponding to the lifting link, and the lifting link is movably disposed between the retaining plate and the mounting frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention first involves placing a sealing ring on the connector head, fixing the hydraulic connector with a clamp, and then controlling the outer sleeve to move downwards, pushing the connector head into the hydraulic connector. Simultaneously, when the inner connecting rod moves downwards, the push rod extends out of the connector head, pushing the sealing ring on the connector head into the sealing groove of the hydraulic connector, thus completing the installation of the sealing ring.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Please combine Figures 1-5 This embodiment provides a straight-core hydraulic connector assembly device. A sealing ring should be installed inside the straight-core hydraulic connector. This embodiment is mainly used to install the sealing ring into the straight-core hydraulic connector.

[0029] A straight-core hydraulic connector assembly device includes a mounting frame 1. Firstly, to facilitate the installation process, the hydraulic connector needs to be fixed in place. Therefore, a clamping plate 2 is provided on the mounting frame 1. Specifically, the clamping plate 2 includes a fixed clamping plate 21 and a movable clamping plate 22. V-shaped notches are provided on opposite sides of the fixed clamping plate 21 and the movable clamping plate 22 for fixing the hydraulic connector. Firstly, the fixed clamping plate 21 is fixedly connected to the mounting frame 1. To install the movable clamping plate 22, a dovetail-shaped limiting groove 23 is provided on the mounting frame 1. A limiting slider 24 is slidably installed within the limiting groove 23, and the top end of the limiting slider 24 is fixedly connected to the movable clamping plate 22. Therefore, the movable clamping plate 22 can only move along the direction of the limiting groove 23.

[0030] Additionally, a spring rod 25 is fixedly connected to the movable clamping plate 22 facing the fixed clamping plate 21, and a through hole is provided on the fixed clamping plate 21, through which the spring rod 25 passes. Therefore, when the movable clamping plate 22 is moved away from the fixed clamping plate 21, the spring on the spring rod 25 will be compressed. In the initial state (without external force), the movable clamping plate 22 will be in contact with the fixed clamping plate 21.

[0031] A sleeve assembly 3 is provided at the position directly opposite the clamping plate 2. The sleeve assembly 3 includes an outer sleeve 4 and an inner connecting rod 5.

[0032] A limiting ring 6 is fixedly connected to the outer tube 4, and a support frame 8 is fixedly connected to the mounting bracket 1. The outer tube 4 is movably installed inside the support frame 8 and can move up and down. The limiting ring 6 is used to limit the up and down movement of the outer tube 4. In addition, a second spring 7 is sleeved on the outer wall of the outer tube 4. When the outer tube 4 moves downward, it will cooperate with the limiting ring 6 to compress the second spring 7.

[0033] Because a sealing ring needs to be installed inside the hydraulic connector, a connector 9 is provided at the bottom of the outer sleeve 4 to facilitate installation. The connector 9 is stepped, with its upper end fixedly connected to the outer sleeve 4, while the sealing ring can be fitted onto the lower part of the connector 9. The connector 9 can be inserted into the hydraulic connector along with the sealing ring. Several push holes 10 are also provided on the connector 9; these are through holes, and the push holes 10 are arranged in a ring. Since the connector 9 needs to enter the hydraulic connector, it can be made of a flexible material (a hydraulic connector with a hardness lower than steel) to prevent accidental compression damage to the inside of the hydraulic connector.

[0034] Furthermore, the lower end of the aforementioned connecting rod is installed inside the outer sleeve 4. The connecting rod can move up and down inside the outer sleeve 4. A first spring 11 is fitted onto the outer side of the connecting rod. It should be noted that the spring constant of the first spring 11 is greater than that of the second spring 7. That is, the first spring 11 requires a greater force to compress. Stepped structures are provided on the inner wall of the outer sleeve 4 and the outer wall of the inner connecting rod 5, and the first spring 11 abuts against these stepped structures. Therefore, when the outer sleeve 4 is stationary, if the inner connecting rod 5 moves downwards, it will compress the first spring 11.

[0035] Additionally, a push rod 12 is fixedly connected to the bottom of the inner connecting rod 5. Several push rods 12 are arranged in a ring at the bottom of the inner connecting rod 5. The positions of the push rods 12 correspond one-to-one with the positions of the aforementioned push holes 10. When the inner connecting rod 5 moves, it can push the push rods 12 out of the push holes 10. At this time, the push rods 12 will contact the sealing ring sleeved on the connector 9.

[0036] To drive the sleeve assembly 3 to move up and down, a drive mechanism 13 is provided. The drive mechanism 13 includes a hydraulic telescopic rod 131, a lifting connecting rod 132, and a connecting block 133. First, the hydraulic telescopic rod 131 is fixedly installed on the outer side wall of the mounting frame 1, while the lifting connecting rod 132 is movably installed on the inner side wall of the mounting frame 1, and the lifting connecting rod 132 is fixedly connected to the top of the aforementioned inner connecting rod 5. The connecting block 133 penetrates the mounting frame 1 and is fixedly connected to one end of the lifting connecting rod 132 and the hydraulic telescopic rod 131, respectively. A long, narrow through hole is provided in the mounting frame 1 at the position corresponding to the connecting block 133.

[0037] Therefore, by controlling the extension or retraction of the hydraulic telescopic rod 131, the lifting link 132 can be moved up and down simultaneously via the connecting block 133. To ensure stable up-and-down movement of the lifting link 132, a locking plate 134 is also provided. Both right-angle locking plates 134 are fixedly connected to the mounting bracket 1. The lifting link 132 is movably positioned in the gap between the locking plates 134 and the mounting bracket 1, thus allowing only up-and-down movement.

[0038] The implementation process and principle of a straight-core hydraulic joint assembly device in this application embodiment are as follows:

[0039] (i) Pull the movable clamp 22 to move it away from the fixed clamp 21. At this time, the spring on the spring rod 25 is compressed. Then place the straight-core hydraulic connector to be installed with the sealing ring between the fixed clamp 21 and the movable clamp 22. Release the movable clamp 22. Under the action of the spring's restoring force, the movable clamp 22 will cooperate with the fixed clamp 21 to fix the hydraulic connector. Then put the sealing ring on the lower end of the connector 9.

[0040] (ii): Through the cooperation of the hydraulic telescopic rod 131 and the connecting block 133, and the lifting link 132, the inner link 5 is driven to move downward;

[0041] Because the spring constant of the first spring 11 is greater than that of the second spring 7, when the inner connecting rod 5 moves downward, the outer sleeve 4 also moves downward, and at this time, the outer sleeve 4 and the inner connecting rod 5 move downward together. The second spring 7 is compressed first. The connector 9 also moves downward together until the connector 9 enters the interior of the lower hydraulic joint.

[0042] At this point, due to the restriction of the limiting ring 6 on the outer support frame 8, the outer sleeve 4 cannot continue to move downwards. If the inner connecting rod 5 continues to move downwards at this time, it will begin to compress the first spring 11. At the same time, it will push the push rod 12 to move towards the connector 9. The push rod 12 continues to move until one end of it protrudes through the push hole 10 on the connector 9 and contacts the sealing ring below;

[0043] As push rod 12 continues to move, it pushes the sealing ring downwards from above, causing the sealing ring to detach from connector 9 and enter the sealing groove of the hydraulic connector. This completes the installation of the sealing ring.

[0044] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
