Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tools, and in particular to a brake cup disassembly and assembly tool. Background Technology

[0002] In the braking system of rail vehicles, the piston cup on the brake piston is a critical sealing component, and its sealing performance directly affects braking effect and safety. During actual maintenance or replacement, it is necessary to remove the piston cup from the brake piston, ensuring that both the brake piston and the piston cup are free of scratches and damage to guarantee the quality of subsequent assembly. However, current piston cup disassembly operations lack specialized tooling, relying mainly on manual prying with tools such as screwdrivers. Operators must gradually apply force along the outer edge of the piston to separate the piston cup from it. However, manually prying the piston cup is time-consuming and labor-intensive, especially in large-scale maintenance scenarios, severely impacting work efficiency. Furthermore, during prying, the disassembly tool may directly contact the surface of the piston cup or brake piston, causing scratches or cracks on the piston cup surface or abrasions on the brake piston surface, thus affecting the reuse value of the components. Therefore, how to efficiently disassemble the piston cup and minimize disassembly damage has become an urgent technical problem to be solved. Utility Model Content

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please refer to the following: Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a brake cup disassembly and assembly tool, which includes an installation structure 100, a disassembly structure 200, and a support structure 300. The installation structure 100 includes an installation base 110 and at least two installation portions 120 detachably disposed on the installation base 110, with a disassembly space 10 formed between each installation portion 120 for accommodating the brake piston 20. The disassembly structure 200 includes disassembly members respectively disposed on each installation portion 120, which are adjustablely connected to the corresponding installation portion 120 and can be inserted into the gap between the brake piston 20 and the cup 21. The support structure 300 is disposed on the installation portion 120 and located below the disassembly structure 200, and the support structure 300 is used to support the brake piston 20.

[0044] Overall, when the brake cup disassembly and assembly tool is used, the disassembly structure 200 can be supported by at least two mounting parts 120 provided on the mounting base 110. The disassembly structure 200 includes disassembly parts respectively provided on each of the mounting parts 120. The disassembly parts are adjustablely connected to the corresponding mounting parts 120. By adjusting the position of each disassembly part, the disassembly part can be inserted into the gap between the brake piston 20 and the cup 21. At this time, the cup 21 is blocked by the disassembly part and cannot move down. Thus, the cup 21 on the brake piston 20 can be removed by pressing down the brake piston 20.

[0045] Furthermore, the brake piston cup disassembly and assembly tool is also equipped with a support structure 300. The support structure 300 is set on the mounting part 120 and placed below the disassembly structure 200. The support structure 300 can support the brake piston 20 and prevent the brake piston 20 from falling and being damaged.

[0046] This utility model, through the cooperation of the disassembly structure 200 and the support structure 300, eliminates the need for manual prying to disassemble the diaphragm cup 21. This allows for efficient disassembly of the diaphragm cup 21 on the brake piston 20, effectively reducing damage to the diaphragm cup 21 and brake piston 20 during the disassembly process, lowering the breakage rate, ensuring the integrity and reuse value of the parts, and significantly improving the disassembly efficiency of the diaphragm cup 21, making the entire process more convenient and controllable.

[0047] In one feasible embodiment of this utility model, the mounting structure 100 includes two mounting portions 120 spaced apart on the mounting base 110. The disassembly component is tunably connected to the corresponding mounting portion 120, and the two disassembly components can move closer or further apart from each other. The support structure 300 is rotatably mounted on the mounting portion 120. The support structure 300 has a first angular position and a second angular position. When the support structure 300 is in the first angular position, the support structure 300 can extend into the disassembly space 10 and be used to receive the brake piston 20. When the support structure 300 is in the second angular position, the support structure 300 can be stored in the mounting structure 100.

[0048] The disassembly structure 200 can be supported by two mounting parts 120 provided on the mounting base 110. The disassembly structure 200 includes two disassembly parts that can move closer or further apart from each other. The disassembly parts can be inserted into the gap between the brake piston 20 and the cup 21. At this time, the cup 21 is blocked by the disassembly parts and cannot move down. Thus, the cup 21 on the brake piston 20 can be removed by pressing down the brake piston 20.

[0049] Furthermore, when the support structure 300 can be rotated to the first angle position, it can support the brake piston 20, preventing it from falling and being damaged. Also, when the support structure 300 can be rotated to the second angle position, it can be stored in the mounting structure 100 without occupying additional space.

[0050] Furthermore, the brake cup disassembly and assembly fixture allows for the rapid installation of the brake cup 21 onto the brake piston 20, thereby improving the installation efficiency of the brake cup 21. Specifically, by adjusting the positions of the two disassembly components, they are positioned far apart to avoid interference between the brake cup 21 and the brake piston 20. The support structure 300 is then switched to the first angle position, where it supports the brake piston 20, preventing displacement during the installation of the brake cup 21 and improving installation accuracy. The brake cup 21 can then be initially fitted onto the brake piston 20, and subsequently pressed down to quickly engage it onto the brake piston 20, thus completing the installation operation of the brake cup 21.

[0051] In embodiments of this utility model, multiple sets of two mounting parts 120 can be provided, with two mounting parts 120 in the same set arranged opposite to each other. Designers can adjust the specific number and arrangement of the mounting parts 120 according to usage needs, and no specific limitations are imposed here.

[0052] In one feasible embodiment, four mounting portions 120 are provided. In another feasible embodiment, six mounting portions 120 are provided. By providing multiple mounting portions 120, the support stability can be improved synergistically, resulting in better performance.

[0053] In an embodiment of this utility model, the disassembly component includes a disassembly plate 210, which is used to insert into the gap between the brake piston 20 and the piston cup 21.

[0054] By setting a disassembly plate 210 that can be inserted into the gap between the brake piston 20 and the diaphragm cup 21, the diaphragm cup 21 is effectively supported and fixed. During the disassembly process, force can be applied evenly, avoiding damage to the diaphragm cup 21 or the brake piston 20 due to excessive local force, thus improving the stability and efficiency of the disassembly operation.

[0055] Specifically, such as Figure 1 In the embodiment shown, when the brake piston 20 to be disassembled is located in the disassembly space, the two disassembly plates 210 are arranged approximately symmetrically along the radial direction of the brake piston 20.

[0056] The two disassembly plates 210 can slide relative to each other in the radial direction of the brake piston 20. The two disassembly plates 210 approach each other so that they can be inserted into the gap between the brake piston 20 and the cup 21 to support the cup 21. At this time, the brake piston 20 is pressed down by the press, and the cup 21 is blocked by the two disassembly plates 210 and cannot move down further, so that the cup 21 is separated from the brake piston 20, which helps to reduce the damage rate of the cup 21 and the brake piston 20 in the disassembly process.

[0057] In the embodiments of this utility model, such as Figure 1 and Figure 2 In the embodiment shown, the disassembly plate 210 includes a main body portion 211 and a blade-shaped portion 212 integrally disposed with the main body portion 211. The thickness of the blade-shaped portion 212 gradually decreases in the direction away from the main body portion 211.

[0058] By gradually reducing the thickness of the blade-shaped portion 212 in the direction away from the main body portion 211, the convenience and accuracy of inserting the disassembly plate 210 into the gap between the brake piston 20 and the cup 21 are effectively improved. This reduces the resistance during insertion and ensures that the disassembly plate 210 can be inserted deeper and more stably into the gap between the brake piston 20 and the cup 21. This improves the uniformity of force and operational stability during disassembly and further reduces the risk of damage to the cup 21 and the brake piston 20 during disassembly.

[0059] Designers can adjust the specific structure of the blade-shaped part 212 according to the needs of use. For example, the cross-section of the blade-shaped part 212 is roughly triangular, and no specific restrictions are made here.

[0060] In this embodiment of the invention, the blade-shaped portion 212 is arc-shaped along the circumference of the disassembly space 10. By making the blade-shaped portion 212 arc-shaped, it can better fit the curved surface structure of the cup 21, effectively increasing the contact area between the disassembly plate 210 and the cup 21, thereby improving the uniformity of force during disassembly, ensuring that the disassembly plate 210 is more stable and reliable during insertion and support, and further improving the safety and efficiency of disassembling the cup 21.

[0061] Specifically, such as Figure 4 In the embodiment shown, the blade-shaped portion 212 includes a cutting edge plane 2121 and an inclined cutting edge slope 2122, which clamp the main body forming the blade-shaped portion 212.

[0062] During the use of the disassembly plate 210, the cutting edge plane 2121 is positioned above and the cutting edge bevel 2122 is positioned below. At this time, the cutting edge plane 2121 abuts against the leather cup 21 to prevent the leather cup 21 from moving downwards. Thus, under the action of the press's downward piston, the leather cup 21 can be disengaged from the brake piston 20. Positioning the cutting edge plane 2121 above and the cutting edge bevel 2122 below avoids the problem of the disassembly plate 210 being squeezed to both sides due to insufficient fastening force between the disassembly plate 210 and the mounting part 120.

[0063] Of course, in other feasible embodiments, the cutting edge plane 2121 can be set at the bottom and the cutting edge inclined surface 2122 at the top. In this case, it is necessary to ensure that the fastening force between the disassembly plate 210 and the mounting part 120 is sufficient to prevent the disassembly plate 210 from being squeezed to both sides.

[0064] In the embodiments of this utility model, such as Figure 1 The embodiment shown includes a connecting bolt 130 in the brake cup disassembly and assembly tooling. The disassembly plate 210 is provided with a strip-shaped through hole 220 extending along the first direction F. The top of the mounting part 120 is provided with a mounting hole 121. The connecting bolt 130 passes through the strip-shaped through hole 220 and is threadedly connected to the mounting hole 121.

[0065] By providing a strip-shaped through hole 220 extending along the first direction F on the disassembly plate 210, when the connecting bolt 130 passes through the mounting hole 121 and the strip-shaped through hole 220, the connecting bolt 130 can be loosened so that the disassembly plate 210 can be flexibly adjusted by means of the strip-shaped through hole 220.

[0066] Furthermore, the two disassembly plates 210 are arranged opposite each other on both sides of the brake piston 20, so that the two disassembly plates 210 can approach or separate from each other. By adjusting the disassembly plates 210, the disassembly plates 210 can be inserted into the gap between the brake piston 20 and the disassembly plates 210.

[0067] Designers can adjust the specific direction of the first direction F according to usage needs, and no specific restrictions are imposed here. Preferably, the first direction F is any horizontal direction, and the two disassembly plates 210 are arranged at intervals along the first direction.

[0068] When the brake piston 20 is placed in the disassembly space 10, one of the radial directions of the brake piston 20 can be parallel to the first direction, so that the two disassembly plates 210 can be adjusted in the radial direction of the brake piston 20, which plays a centering and clamping role and ensures the disassembly stability of the cup 21.

[0069] In this embodiment of the invention, the designer can adjust the gap between the two disassembly plates 210 according to the needs of use to accommodate the disassembly of brake pistons 20 and piston cups 21 of different sizes, without making specific numerical limitations. Among them, piston cups 21 of different sizes include, but are not limited to, piston cups 21 with diameters of 7 inches, 8 inches, 9 inches, and 10 inches.

[0070] During disassembly, the brake piston 20 is lifted upwards until the gap between the brake piston 20 and the piston cup 21 is approximately at the same level as the disassembly plate 210. The two disassembly plates 210 are then pushed inwards, inserting them into the gap between the brake piston 20 and the piston cup 21. Next, the two disassembly plates 210 are secured with connecting bolts 130, and the brake piston 20 is pressed down by the press head until it disengages from the piston cup 21. Finally, the press head is lifted, the brake piston 20 and piston cup 21 are removed, and the disassembly plates 210 are reset.

[0071] In the embodiments of this utility model, such as Figure 1 and Figure 3 In the embodiment shown, the support structure 300 includes support members 310 respectively disposed on each mounting part 120. The support members 310 are rotatably disposed on the corresponding mounting part 120 and positioned below the disassembly structure 200.

[0072] Specifically, there are two support components 310. The two support components 310 are respectively located below the corresponding disassembly plate 210. The two support components 310 can provide multi-point support by working together, which helps to improve the stability of the support.

[0073] When the disassembly plate 210 is inserted into the gap between the brake piston 20 and the piston cup 21, the blade-shaped part 212 of the disassembly plate 210 can support the piston cup 21, while the brake piston 20 is in a suspended state. At this time, by rotating the support member 310, the support member 310 is rotated to be below the brake piston 20.

[0074] When the brake piston 20 is pressed down by the press to disengage it from the piston cup 21, the brake piston 20 is supported by the support member 310, preventing it from falling and being damaged. The support angle and position of the support member 310 can be flexibly adjusted according to actual needs to better accommodate brake pistons 20 of different shapes and sizes; no specific limitations are imposed here.

[0075] Designers can adjust the gap between the brake piston 20 and the support member 310 when the brake piston 20 is in a suspended state according to usage requirements; no specific limitations are imposed here. Preferably, when the brake piston 20 is in a suspended state, the gap between the brake piston 20 and the support member 310 is 10mm to 20mm.

[0076] In an embodiment of this utility model, the support structure 300 further includes a rotating shaft 320 respectively disposed on each mounting part 120. The rotating shaft 320 is disposed along the height direction and rotates the corresponding mounting part 120. The mounting part 120 also includes a clearance space 140 disposed around the rotating shaft 320. The support member 310 is rotatably connected to the rotating shaft 320. When the support member 310 is in a first angle position, at least a portion of the support member 310 can extend into the disassembly space 10 and be used to receive the brake piston 20. When the support member 310 is in a second angle position, the support member 310 can be stored in the clearance space 140.

[0077] By arranging the rotating shaft 320 along the height direction on the mounting portion 120, the support member 310 can rotate circumferentially around the rotating shaft 320. Furthermore, the mounting portion 120 is provided with a clearance space 140 around the rotating shaft 320, so that the support member 310 can be rotated and stored in the clearance space 140, thus preventing the support member 310 from being exposed and affecting the insertion and removal of the brake piston 20.

[0078] Furthermore, the support member 310 can also extend out of the clearance space 140 by rotating, so that the support member 310 can rotate to the bottom of the brake piston 20 to support the brake piston 20. This not only improves the space utilization of the tooling, but also ensures the flexibility and convenience during disassembly and assembly. At the same time, it reduces the operational limitations or risk of damage to parts caused by the fixed and non-adjustable support member 310, further improving the applicability and efficiency of the tooling.

[0079] Designers can adjust the specific structure of the support member 310 according to the usage requirements, and no specific restrictions are imposed here. Preferably, the support member 310 includes a rotating part 311 and a supporting part 312 protruding from the rotating part 311. The rotating part 311 is provided with a mounting through hole for the rotating shaft 320 to pass through.

[0080] Furthermore, such as Figure 3 In the embodiment shown, the support portion 312 is provided with a support plane, which can make surface contact with the brake piston 20, and has a larger support area, thereby improving support stability.

[0081] In an embodiment of this utility model, the mounting part 120 includes a support column, and the mounting base 110 includes a base plate, with the support column and the base plate being detachably connected.

[0082] By detachably connecting the support column of the mounting part 120 to the base plate of the mounting base 110, the modularity and applicability of the brake cup disassembly and assembly tooling are effectively improved.

[0083] Furthermore, by separating the support column from the base plate, it facilitates the transportation, storage, and maintenance of the brake cup assembly and disassembly tooling, significantly reducing usage costs and improving the tooling's flexibility and service life.

[0084] Designers may adjust the specific construction of the detachable structure 200 between the support column and the base plate according to the needs of use, without making specific restrictions here.

[0085] In one feasible embodiment, such as Figure 1 In the embodiment shown, the bottom of the support column is provided with a plug 122, and the base plate is provided with a plurality of plug holes 111 spaced apart. The plug 122 can be detachably plugged into one of the plug holes 111.

[0086] Furthermore, the multiple sockets 111 can be configured with different sizes, and various support posts of different sizes can be preset, with each support post of different sizes matching each socket 111. Users can quickly replace the support posts of different sizes according to actual needs, thereby better adapting to different models of brake pistons 20 and cup 21 assemblies.

[0087] Similarly, designers can pre-set various sizes of disassembly plates 210, and users can quickly replace the disassembly plates 210 of different sizes according to actual needs, so as to better adapt to different sizes of leather cups 21 and improve the flexibility of use.

[0088] Please refer to the following: Figure 5 , Figure 6 and Figure 7 As shown, in another feasible embodiment of the present invention, the support structure 300 includes a support end face 330 disposed on the mounting portion 120 and a top rod 230 protruding from the corresponding support end face 330. At least a portion of the mounting portion 120 protrudes from the support end face 330 to form a mounting seat 150, and the disassembly component is rotatably disposed on the mounting seat 150.

[0089] Specifically, the support end face 330 is arranged horizontally, and the mounting base 150 is placed on the outside of the support end face 330. The mounting base 150 has an inner wall that is approximately arc-shaped. Designers can adjust the specific structure of the top rod 230 according to the needs of use. For example, the top rod 230 can be set as a cylinder. No specific restrictions are made here.

[0090] During the disassembly and assembly process, the brake piston 20 is placed in the disassembly space 10 held by each mounting seat 150. By setting the arc-shaped mounting seat 150, the brake piston 20 can fit more closely, thereby improving the limiting stability of the brake piston 20, avoiding displacement of the brake piston 20, and ensuring the stability of disassembly and assembly.

[0091] Furthermore, by rotatably mounting the disassembly component on the corresponding mounting base 150, the position can be adjusted by rotating the disassembly component, thereby allowing the disassembly component to be rotatably inserted into the gap between the brake piston 20 and the cup 21, thus providing better adjustment flexibility.

[0092] Furthermore, by rotating the disassembly component, it can be disengaged from the gap between the brake piston 20 and the piston cup 21, thereby preventing the disassembly component from interfering with the insertion and removal of the brake piston 20. Designers can adjust the specific structure and installation method of the disassembly component according to usage needs, and no specific restrictions are imposed here.

[0093] In one feasible embodiment, the disassembly component includes a disassembly plate 210, which has a connecting through hole. The brake cup disassembly and assembly tool also includes a connecting bolt. The top of the mounting base 150 has a mounting hole 121, and the connecting bolt passes through the connecting through hole and is threadedly connected to the mounting hole 121.

[0094] like Figure 6 In the illustrated embodiment, during the disassembly of the piston cup 21, the brake piston 20 is placed in the disassembly space 10. A push rod 230 passes through the side hole 22 of the brake piston 20 and abuts against the piston cup 21, thus supporting the brake piston 20. At this time, the disassembly plate 210 and the gap between the brake piston 20 and the piston cup 21 are approximately at the same horizontal level. The disassembly plate 210 is rotated inward, thereby rotatably inserting itself into the gap between the brake piston 20 and the piston cup 21, using the disassembly plate 210 to support the piston cup 21. Then, the press head of the press is used to press down on the brake piston 20 until the brake piston 20 disengages from the piston cup 21. Finally, the press head is lifted, and the brake piston 20 and piston cup 21 are removed, and the disassembly plate 210 is reset.

[0095] Furthermore, such as Figure 8 As shown, the support structure 300 also includes pads 340 corresponding to each push rod 230. The pads 340 are provided with clearance holes 341 for the push rods 230 to pass through. The pads 340 have an installation position that is fitted onto the push rods 230 and a disassembly position that is detached from the push rods 230. When the pads 340 are in the installation position, the pads 340 can be used to support the brake piston 20. When the pads 340 are in the disassembly position, the push rods 230 can be used to pass through the side hole 22 of the brake piston 20 and push out the cup 21.

[0096] Specifically, the length of the clearance hole 341 of the pad 340 is approximately the same as that of the push rod 230. When the pad 340 and the push rod 230 are inserted into each other, the push rod 230 cannot be fully inserted into the side hole 22 of the brake piston 20, so that the pad 340 can support the brake piston 20 more stably.

[0097] like Figure 7In the embodiment shown, during the installation of the cup 21, the pad 340 is placed on the support end face 330, and then the brake piston 20 is placed into the disassembly space 10 and abuts against the pad 340. The pad 340 cooperates with the mounting seat 150 to limit the brake piston 20. Then the cup 21 can be initially fitted onto the brake piston 20, and then the cup 21 is pressed down to quickly snap the cup 21 into the brake piston 20, thereby realizing the installation operation of the cup 21.

[0098] Designers can adjust the specific number of mounting parts 120 and pads 340 according to usage needs. For example, four mounting parts 120 and four pads 340 are provided. No specific limit is set here.

[0099] In the embodiments of this utility model, multiple mounting parts 120 with different disassembly structures 200 can be pre-set, such as the two feasible embodiments mentioned above. During use, the corresponding mounting parts 120 can be installed on the mounting base 110 according to the disassembly and assembly needs, thereby forming a more adaptable brake cup disassembly and assembly tool, which helps to improve the disassembly and assembly effect of the brake cup 21.
