Abstract
Description
Technical Field
[0001] This invention relates to the field of specialized disassembly tools, specifically a shielding cover disassembly fixture and its usage method. Background Technology
[0002] In equipment assembly and maintenance, the shielding cover is placed on the outside of the conductor and locked in place by spring pins installed inside the conductor. When disassembling this type of shielding cover, the spring pins hidden inside the shielding cover must be pressed inward to unlock it before the shielding cover body can be slid off the conductor. Conventional disassembly operations rely on operators holding a general probe or screwdriver or other hard tools through the holes in the shielding cover to press the spring pins.
[0003] Using this operating method, it is extremely difficult for operators to stably control the pressure and direction applied to the spring pin, resulting in uneven force on the pin and a very cumbersome unlocking process. Because operators need to maintain the continuous pressing unlocking state of the hard tool with one hand while simultaneously applying force to pull the shielding cover outward with the other hand, the coordination of the actions is very difficult, leading to low overall disassembly efficiency. When general-purpose metal tools are pressed or pulled out close to the outside of the shielding cover, the hard surface of the tool will directly rub and impact the shielding cover body, causing substantial physical damage such as scratches and deformation on the outer surface of the shielding cover. At the same time, conventional tools do not have precise positioning and guiding reset functions, and tool jamming will occur when working in holes. After completing one disassembly, it is not possible to quickly enter the next disassembly operation, which limits the continuity of batch disassembly operations. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a shielding cover disassembly fixture and its usage method, which solves the problems of low disassembly efficiency due to difficulties in unlocking operation coordination, scratches on the outer surface of the shielding cover caused by direct contact with hard tools, and tool jamming affecting continuous disassembly operations due to the lack of a reset structure.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The first aspect of the present invention provides a shielding cover disassembly fixture, including a hand-tightening bolt, an outer ring and a top pin. The hand-tightening bolt is threadedly connected to the inner side of the outer ring, and the top pin is slidably connected to the inner side of the outer ring. The bottom of the hand-tightening bolt abuts against the top of the top pin, and a stepped hole is provided on the inner side of the outer ring.
[0007] Preferably, a compression spring is sleeved on the outer side of the top pin, the top of the compression spring is fixedly connected to the outer side of the top pin, and the bottom of the compression spring is fixedly connected to the inner side of the outer ring.
[0008] Preferably, a rubber pad is fixedly connected to the inner side of the outer ring, and the inner side of the rubber pad has a waist-shaped hole.
[0009] Preferably, a shielding cover body is slidably connected to the inner side of the rubber pad, and a conductor is slidably connected to the inner side of the shielding cover body.
[0010] Preferably, the top pin is slidably connected to the inside of the shield body.
[0011] Preferably, a spring pin is fixedly connected to the inner side of the conductor.
[0012] Preferably, the bottom of the top pin abuts against the top of the spring pin.
[0013] A second aspect of the present invention also provides a method for using a shielding cover disassembly fixture, comprising the following steps:
[0014] Perform disassembly and assembly of the shielding cover using the tooling.
[0015] Slide the shielding cover disassembly tool into the outside of the shielding cover body;
[0016] Tighten the hand-tightening bolt to make the top pin slide. The bottom of the top pin abuts against and pushes the spring pin to slide inside the body, so that the spring pin separates from the shield body.
[0017] Remove the shielding cover body along with the shielding cover disassembly tooling.
[0018] Preferably, the step of disassembling and assembling the shielding cover includes:
[0019] Fit the compression spring onto the outside of the top pin, and place the top pin and compression spring into the stepped hole on the inside of the outer ring; thread the hand-tightening bolt onto the inside of the outer ring; fix the rubber pad onto the inside of the outer ring, aligning the waist-shaped hole on the inside of the rubber pad with the stepped hole on the inside of the outer ring.
[0020] Preferably, the step of removing the shielding cover body together with the shielding cover disassembly fixture includes:
[0021] Slide the shield body along the outside of the conductor to separate it from the shield body along the outside of the shield body; separate the shield body disassembly tool from the outside of the shield body.
[0022] This invention provides a tooling for disassembling a shielding cover and its method of use. It has the following beneficial effects:
[0023] 1. This invention, by setting a linkage structure between the hand-tightening bolt and the top pin, allows the operator to screw the hand-tightening bolt inward and directly push the top pin, causing the bottom of the top pin to pass through the shield body and abut against and press the spring pin. The cooperation between the hand-tightening bolt and the top pin converts the external rotational motion into an internal linear thrust, which can stably force the spring pin to retract and release the lock on the shield body, simplifying the unlocking and disassembly steps of the shield and improving the efficiency of the overall disassembly operation.
[0024] 2. The present invention has a rubber pad fixedly connected to the inner side of the outer ring. During the disassembly operation, the outer ring of the tooling is sleeved on the outside of the shielding cover body and slides and separates along the conductor together with the shielding cover body. The rubber pad is located between the outer ring and the shielding cover body, avoiding direct contact between the outer ring and the outer surface of the shielding cover body. The rubber pad provides cushioning throughout the entire process of tooling insertion, positioning and sliding removal, preventing the outer side of the shielding cover body from being scratched and ensuring the integrity of the surface of the removed parts.
[0025] 3. This invention provides a compression spring on the outside of the top pin, with both ends of the spring fixedly connected to the outside of the top pin and the inside of the outer ring, respectively. When the shielding cover is removed and the hand-tightening bolt is loosened and pulled outward, the compression spring releases the stored elastic force and automatically pushes the top pin back to its initial position. The rebound effect of the compression spring prevents the top pin from getting stuck inside the stepped hole, allowing the tooling to quickly return to its standby state after a single use, facilitating the continuous reuse of the tooling.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Example 1:
[0034] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a shielding cover disassembly fixture and its usage method, including a hand-tightening bolt 1, an outer ring 2, and a top pin 3. The hand-tightening bolt 1 serves as the power source of the fixture, the outer ring 2 serves as the main bearing body of the disassembly fixture, and the top pin 3 serves as the force transmission component. The hand-tightening bolt 1 is threadedly connected to the inner side of the outer ring 2, and the top pin 3 is slidably connected to the inner side of the outer ring 2. The outer ring 2 is used to support the hand-tightening bolt 1 and the top pin 3. The bottom of the hand-tightening bolt 1 abuts against the top of the top pin 3. The hand-tightening bolt 1 presses down on the top of the top pin 3 by screwing in the thread on the inner side of the outer ring 2. A stepped hole is provided on the inner side of the outer ring 2.
[0035] A compression spring 4 is fitted on the outer side of the top pin 3. The compression spring 4 serves to support and return the pin to its original position. The top of the compression spring 4 is fixedly connected to the outer side of the top pin 3, and the bottom of the compression spring 4 is fixedly connected to the inner side of the outer ring 2. The compression spring 4 is connected between the top pin 3 and the outer ring 2. When the hand-tightening bolt 1 is loosened to the outside, the compression spring 4 uses its elasticity to push the top pin 3 back to its initial position. Under the push of the hand-tightening bolt 1, the top pin 3 overcomes the resistance of the compression spring 4 and slides inward. A rubber pad 5 is fixedly connected to the inner side of the outer ring 2. The rubber pad 5 serves to cushion and protect against scratches. A waist-shaped hole is opened on the inner side of the rubber pad 5.
[0036] Please see the appendix Figure 3 -Appendix Figure 5 In a preferred embodiment of the present invention, a shielding cover body 6 is slidably connected to the inner side of the rubber pad 5, and an outer ring 2 is sleeved on the outside of the shielding cover body 6 to provide an operating platform. The rubber pad 5 is disposed between the outer ring 2 and the shielding cover body 6 to prevent the hard outer ring 2 from scratching the outer surface of the shielding cover body 6 when it is put on or removed and slid. A conductor 7 is slidably connected to the inner side of the shielding cover body 6, and the shielding cover body 6 is sleeved on the outside of the conductor 7 to provide protection and shielding. The conductor 7 serves as a guide base for the shielding cover body 6 to slide and separate outward during the disassembly process.
[0037] The top pin 3 is slidably connected to the inside of the shielding cover body 6. A spring pin 8 is fixedly connected to the inside of the conductor 7. The conductor 7 is used to fix the spring pin 8 internally and provide a mounting base for the spring pin 8. The spring pin 8 is normally in the pop-out state, locking the shielding cover body 6 onto the conductor 7. The bottom of the top pin 3 abuts against the top of the spring pin 8. The hand-tightening bolt 1 provides a pushing force to push down the spring pin 8. The bottom of the top pin 3 passes through the shielding cover body 6 and precisely abuts against and presses down the top of the spring pin 8 to unlock it. During disassembly, the spring pin 8 is pressed down and retracted by the top pin 3, thereby releasing the locking relationship between the spring pin 8 and the shielding cover body 6 and separating them. After unlocking, the shielding cover body 6 is slidably removed from the conductor 7 along with the disassembly tool.
[0038] Example 2:
[0039] This invention also provides a method for using a shielding cover disassembly fixture, comprising the following steps:
[0040] Perform disassembly and assembly of the shielding cover using the tooling.
[0041] Slide the shielding cover disassembly tool into the outside of the shielding cover body 6;
[0042] Tighten the hand-tightening bolt 1 to make the top pin 3 slide. The bottom of the top pin 3 abuts against and pushes the spring pin 8 to slide inward to the conductor 7, so that the spring pin 8 separates from the shield body 6.
[0043] Remove the shield body 6 along with the shield disassembly fixture.
[0044] The steps for disassembling and assembling the shielding cover include:
[0045] Fit the compression spring 4 onto the outside of the top pin 3, and place the top pin 3 together with the compression spring 4 into the stepped hole on the inside of the outer ring 2; thread the hand-tightening bolt 1 onto the inside of the outer ring 2; fix the rubber pad 5 onto the inside of the outer ring 2, so that the waist-shaped hole on the inside of the rubber pad 5 is aligned with the stepped hole on the inside of the outer ring 2.
[0046] The steps for removing the shielding cover body 6 together with the shielding cover disassembly fixture include:
[0047] Slide the shield body 6 together with the shield disassembly tool along the outside of the conductor 7 to separate them; separate the shield disassembly tool from the outside of the shield body 6.
[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended description and its equivalents.
