Hydrodynamic coupling output end removal tool

Abstract

This invention relates to a disassembly tool for the output end of a hydraulic coupler, comprising a puller, a ball-head push rod, a release sleeve, and an adjusting disc. The puller includes a hydraulic push rod and pull claws. The release sleeve has a central hole with a T-shaped cross-section, a convex ring at the top, and threads on its lower outer wall. The adjusting disc is a circular disc with threads on its inner wall. The inner diameter of the circular disc matches the lower outer diameter of the release sleeve and is smaller than the outer diameter of the top ring of the release sleeve. The ball-head push rod is installed in the central hole of the release sleeve, and its outer diameter is not greater than the inner diameter of the hole. This invention utilizes the engagement between the threads on the outer wall of the release sleeve and the release threads on the inner wall of the deep hole at the output end of the coupler. The force is transmitted through the ball-head push rod to the shaft end of the driven equipment, separating the coupler from the shaft end. The ball-head push rod effectively protects the shaft end of the driven equipment from damage and prevents wear and failure of the release threads.

Description

Technical Field

[0001] This utility model relates to a disassembly device, and more particularly to a hydraulic coupler output end disassembly tool that reduces the coupler damage rate and facilitates disassembly. Background Technology

[0002] The shaft of the hydraulic coupling and the drive motor are generally interference fit. During the disassembly process, the interference fit is usually disassembled by heating and hammering. The hydraulic coupling is mostly made of aluminum, which is easily damaged by hammering, while heating will cause damage to the oil seal. Using hammering and slight heating can easily cause damage to the body and oil seal leakage during disassembly. Moreover, the disassembly is time-consuming, and it is inconvenient to control the hammering force and temperature during construction, which can easily cause damage to the hydraulic coupling. Summary of the Invention

[0003] The present invention aims to solve the problem of difficult disassembly of hydraulic couplers and the easy damage during the disassembly process, and provides a hydraulic coupler output end disassembly tool that reduces the coupler damage rate and facilitates disassembly.

[0004] This utility model discloses a disassembly tool for the output end of a hydraulic coupler. The tool comprises a puller device, a ball-head push rod, a release sleeve, and an adjusting disc. The puller device includes a hydraulic push rod and pull claws. The release sleeve has a central hole with a T-shaped cross-section, a convex ring at the top, and threads on its lower outer wall. The adjusting disc is a circular disc with threads on its inner wall. The inner diameter of the circular disc matches the lower outer diameter of the release sleeve and is smaller than the outer diameter of the top ring of the release sleeve. The ball-head push rod is installed in the central hole of the release sleeve, and its outer diameter is not greater than the inner diameter of the hole. The puller device has at least three pull claws that hook onto the bottom of the circular disc. The bottom end of the hydraulic push rod of the puller device rests against the top of the ball-head push rod.

[0005] The lower outer diameter of the unloading sleeve matches the inner diameter of the hydraulic coupling to be disassembled, and the threads on the outer wall of the unloading sleeve engage with the threads on the inner wall of the hydraulic coupling to be disassembled.

[0006] This utility model discloses a hydraulic coupler output end disassembly tool with a simple structure, scientific design, and convenient use. The tool utilizes the engagement between the threads on the outer wall of the release sleeve and the release threads on the inner wall of the deep hole at the coupler output end. The puller force is transmitted to the shaft end of the driven equipment through the ball-head push rod, separating the coupler from the shaft end under the puller's pulling action. The ball-head push rod effectively protects the shaft end of the driven equipment from damage. The coupler's release threads do not require rotation during disassembly, avoiding wear and failure of the release threads and ensuring a safe and reliable disassembly process. This tool reduces wear on equipment parts during disassembly, can be reused multiple times, and significantly reduces operating and maintenance costs. Attached Figure Description

[0010] Example 1: A tool for disassembling the output end of a hydraulic coupler includes a puller device, a ball-head push rod, a withdrawal sleeve, and an adjusting plate. The puller device includes a hydraulic push rod and pull claws. The withdrawal sleeve has a central hole with a T-shaped cross-section, a convex ring at the top, and threads on its lower outer wall. The adjusting plate is a circular disc with threads on its inner wall. The inner diameter of the circular disc matches the lower outer diameter of the withdrawal sleeve and is smaller than the outer diameter of the top ring of the withdrawal sleeve. The ball-head push rod is installed in the central hole of the withdrawal sleeve, and its outer diameter is not greater than the inner diameter of the hole. The puller device has at least three pull claws that hook onto the bottom of the circular disc. The bottom end of the hydraulic push rod of the puller device rests against the top of the ball-head push rod. The lower outer diameter of the withdrawal sleeve matches the inner diameter of the hydraulic coupler to be disassembled, and the threads on the outer wall of the withdrawal sleeve engage with the threads on the inner wall of the hydraulic coupler to be disassembled.

[0011] When disassembling the hydraulic coupling, first, place the adjusting disc onto the withdrawal sleeve from the bottom. Continuously rotate the adjusting disc until its top surface is firmly against the back of the ring at the top of the withdrawal sleeve. Then, insert the withdrawal sleeve into the deep hole at the output end of the hydraulic coupling to be disassembled, ensuring the threads on the outer wall of the withdrawal sleeve engage with the threads on the inner wall of the deep hole of the hydraulic coupling. Continuously rotate the withdrawal sleeve until at least two-thirds of the threads on the outer wall of the withdrawal sleeve engage with the threads on the inner wall of the deep hole of the coupling. Next, insert the ball-head jack into the round hole in the central shaft of the withdrawal sleeve, with the bottom end of the ball-head jack resting on the shaft head of the driven equipment. Then, install the puller device on the withdrawal sleeve. First, place the bottom end of the hydraulic jack against the top of the ball-head jack. Then, adjust the three claws of the puller device to hook the adjusting disc. Once the adjusting disc and the puller device are secure, connect the puller device to the hydraulic press. Use the hydraulic press and this disassembly tool to remove the hydraulic coupling.
