Description

Technical Field

[0001] This utility model belongs to the technical field of turbine maintenance equipment, specifically relating to a special tooling for disassembling a slider. Background Technology

[0002] In various types of mechanical equipment, the bearing cylinder and its internal slider are common core transmission and load-bearing components. To ensure the stability and accuracy of equipment operation, the bearing cylinder slider is usually installed with an interference fit or a tight fit with parts such as shaft pins and bearings, which makes regular maintenance, slider replacement, or disassembly of damaged parts difficult.

[0003] Currently, the traditional method commonly used in the industry for disassembling such tightly fitted cylinder slides involves using a grinder to flatten the head of the pin, then using a bench vise to forcefully hold the slide body in place. The operator then repeatedly strikes the pin with a hammer and a chisel or chisel, using impact force to forcibly remove the pin from the slide. This entire process relies entirely on manual labor, is physically demanding, and requires a high level of skill and physical strength from the operators. Furthermore, this impact-based disassembly method is inefficient, time-consuming, and severely impacts equipment maintenance progress and downtime.

[0004] During hammering, it is difficult to maintain uniform and axial force, which can easily cause damage, deformation, or even scrapping of precision components such as the slider body, shaft pin threads, or internal bearings. This prevents the reuse of parts, increases maintenance costs, and may even damage the cylinder body. Furthermore, using tools such as grinders and hand hammers also poses certain safety risks. Therefore, there is an urgent need for a specialized tooling for slider disassembly to achieve safe, efficient, and non-destructive disassembly operations. Utility Model Content

[0005] The purpose of this utility model is to provide a special tooling for disassembling a slider, which has the functions of safe, efficient and non-destructive disassembly, and solves the problems of difficult disassembly of the cylinder slider, high labor intensity, low efficiency and easy damage to parts in the prior art.

The front end of the bolt contacts the lifting end of the hydraulic drive device. A top block is provided at the other end of the top of the base, and the front side of the top block is used to place the slider to be disassembled.

[0007] Preferably, the front of the baffle is a vertical plane, the back of the baffle is connected to the reinforcing ribs, and the reinforcing ribs are provided in multiple ways evenly distributed along the width of the baffle, with the bottom of the reinforcing ribs fixedly connected to the base.

Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] In the above diagram, 1 is the base, 2 is the slot, 3 is the baffle, 4 is the reinforcing rib, 5 is the support platform, 6 is the sleeve, 7 is the bolt, 8 is the top block, 9 is the cylinder slider, and 10 is the hydraulic drive device. Detailed Implementation

[0019] 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.

[0020] 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.

[0021] Example 1, as Figure 1 As shown, a special tooling for disassembling a slider includes a base 1, which serves as the basic platform for the entire tooling, supports all other components, and provides stable support for the disassembly operation.

[0022] A vertical baffle 3 is provided at one end of the top of the base 1, and a reinforcing rib 4 is provided on the back of the baffle 3. The baffle 3 serves as a force-bearing stop surface, while the reinforcing rib 4 is used to enhance the rigidity of the baffle 3 and prevent it from bending or deforming under huge axial thrust. Multiple evenly distributed reinforcing ribs 4 effectively disperse the concentrated force to the base 1, ensuring that the baffle 3 can withstand continuous high-pressure thrust without being damaged.

[0023] A slot 2 is provided at the center of the top of the base 1, located in front of the baffle 3. A hydraulic drive device 10 is placed within the slot 2, which serves to accommodate and position the hydraulic drive device 10, preventing movement during operation. The hydraulic drive device 10 is the power source for the entire fixture, providing a smooth, powerful, and controllable axial jacking force. The hydraulic device can generate a large output force with minimal manual input, significantly reducing the operator's workload. Compared to impact hammering, the hydraulic jacking process is slow and linear, and the magnitude and progress of the force can be precisely controlled, fundamentally avoiding damage to parts caused by impact forces.

[0024] A support platform 5 is located at the center of the front side of the slot 2 on the top of the base 1. A sleeve 6 is fixed on the support platform 5, and a bolt 7 is inserted into the sleeve 6. The support platform 5 is used to raise and fix the sleeve 6, so that the center of the sleeve 6 is aligned with the center of the push rod of the hydraulic drive device 10 and the center of the bearing to be disassembled. The sleeve 6 is used to guide and constrain the bolt 7 to ensure axial movement without deflection or rotation, so that the pushing force is accurately and concentrically transmitted to the shaft pin, achieving "non-destructive disassembly". The front end of the bolt 7 contacts the lifting end of the hydraulic drive device 10. The bolt 7 acts as a force transmission rod, receiving the thrust of the hydraulic drive device 10 at one end and applying the force to the shaft pin or bearing inside the bearing cylinder slider 9 at the other end. The diameter and length of the bolt 7 can be replaced according to different models of bearing cylinder slider 9, which enhances the versatility of the tooling. It uses standard parts or easily machined parts, resulting in low cost and high reliability.

[0025] A top block 8 is provided at the other end of the base 1. The front side of the top block 8 is used to place the cylinder slide block 9 to be disassembled. The function of the top block 8 is to support and position the cylinder slide block 9 to be disassembled. The bearing hole on the cylinder slide block 9 is aligned with the center of the bolt 7. The top block 8 is made of copper or mild steel. A protective liner is provided on the outer wall of the top block 8 to prevent scratching or crushing the surface of the cylinder slide block 9.

[0026] The specific design of the aforementioned key components will be discussed in detail below:

[0027] The front of the baffle 3 is a vertical plane, and the back of the baffle 3 is connected to the reinforcing ribs 4. Multiple reinforcing ribs 4 are evenly distributed along the width of the baffle 3, and the bottom of the reinforcing ribs 4 are fixedly connected to the base 1, typically by welding. The vertical plane provides a reliable force reference surface, preventing the cylinder slider 9 from deflecting or slipping under pressure, ensuring that the jacking force is fully used for disassembly. The evenly distributed multiple reinforcing ribs 4 effectively disperse and transfer the huge concentrated load generated by the hydraulic jack to the entire base 1, enhancing the rigidity and bending strength of the baffle 3, avoiding the risk of deformation or tearing of the baffle 3 under high pressure, and ensuring the long-term durability and safety of the tooling.

[0028] The top of the bolt 7 extends into a sleeve 6 and is provided with a nut, which has a hexagonal head. The extended sleeve 6 allows the operator to observe the travel and position of the bolt 7, and the hexagonal head nut can block the sleeve 6 to prevent the bolt 7 from being completely pushed into the sleeve 6 and difficult to remove.

[0029] The bearing is located at the center of the cylinder slider 9, and the bearing contacts the bottom end of the bolt 7. Since the bearing is pre-installed at the center of the cylinder slider 9, during disassembly, the rear end of the bolt 7 directly contacts the inner ring or end face of the bearing, and the pushing force acts directly and precisely on the part that needs to be ejected.

[0030] The central area of ​​the top block 8 has a hollow structure for the bearing to exit. The hollow structure is a through hole or groove, providing a channel and space for the successfully ejected bearing or shaft pin to exit. During disassembly, once the part begins to move, it can be completely ejected in one go and fall through the hollow, without having to stop the operation midway to remove the workpiece or the removed part, thus improving work efficiency.

[0031] The hydraulic drive device 10 is a hydraulic jack, which is placed in the slot 2, with the top of the lifting piston rod in contact with the top of the bolt 7. The hydraulic jack, as a power source, is directly placed in the slot 2 on the base 1, with the top of the lifting piston rod of the hydraulic jack in contact with the top of the bolt 7. The slot 2 is a positioning structure that precisely limits the hydraulic jack to a predetermined position, ensuring that the lifting force always coincides with the axis of the bolt 7.

[0032] The base 1 is also equipped with multiple leveling feet (not shown in the figure) at its bottom. These leveling feet are adjustable-height anchor bolts. By installing multiple adjustable-height anchor bolts at the bottom of the base 1 as leveling feet, the levelness of the entire fixture can be precisely adjusted by rotating each anchor bolt.

[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
