Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, and more specifically, to heavy-duty bearing assembly fixtures. Background Technology

[0002] Heavy-duty bearings are a type of special heavy-duty bearing suitable for high-load, low-speed, or intermittent operation conditions. They are widely used in wind power, metallurgy, mining, heavy machine tools, port machinery, and other fields. Their core function is to support the rotating components of heavy equipment, such as spindles, rollers, and gear shafts, while simultaneously transmitting radial and axial loads and reducing frictional losses. During operation, heavy-duty bearings utilize the core logic of "rolling friction replacing sliding friction" to achieve load transmission and drag reduction. When the rotating components of the equipment drive the inner ring of the heavy-duty bearing to rotate, the inner ring raceway pushes the rolling elements along the outer ring raceway in pure rolling motion, avoiding direct sliding contact between the inner and outer rings and significantly reducing the coefficient of friction. The line or point contact structure between the raceway and the rolling elements can evenly distribute the radial and axial loads applied by the equipment onto multiple rolling elements. The load is transferred from the inner ring to the outer ring through the cyclic rolling of the rolling elements, ensuring stable support of rotating parts under high load conditions, maintaining the operating accuracy of the equipment, and extending its service life. During the assembly of heavy bearings, support fixtures are generally used to support the heavy bearings during the assembly process, so that workers can perform assembly connection operations between the heavy bearings and the shaft. Since the force applied during the assembly of heavy bearings with external shafts directly affects the assembly efficiency of heavy bearings, it is necessary to perform assembly force operations.

[0003] In related technologies, during the use of heavy bearing assembly fixtures, the heavy bearings are generally supported and stabilized by support fixtures so that the workers can maintain the position of the heavy bearings and perform assembly operations by connecting the heavy bearings and shafts, thereby enabling their use.

[0004] However, in the current use of heavy bearing assembly fixtures, since the heavy bearing is assembled using an interference fit, after the heavy bearing is heated, it is slowly hammered into the shaft with a copper rod. But if the hammering is too slow, the temperature of the heavy bearing will drop, which will cause the heavy bearing to jam. If it cannot be positioned in time, the heavy bearing will be stuck in other positions, resulting in inaccurate assembly position and affecting the convenience and efficiency of the heavy bearing assembly operation. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a heavy-duty bearing assembly fixture that overcomes or at least partially solves the above technical problems.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a heavy bearing assembly fixture, including a positioning block, on the top of which a heavy bearing is mounted, and on the bottom left side of which a telescopic hydraulic cylinder is mounted.

[0008] Assembly tooling mechanism, the assembly tooling mechanism including:

[0009] Assembly slot; the assembly slot is located on the right side of the top of the positioning block, and a retaining ring is installed on the left side of the inner wall of the assembly slot. The heavy bearing is located inside the assembly slot and contacts the retaining ring.

[0010] Receiving hole; the receiving hole is opened on the left side of the inner wall of the assembly groove, and the receiving hole is connected to the retaining ring.

[0011] In a preferred embodiment, guide openings are provided on both sides of the bottom of the positioning block, and guide rails are movably connected inside the guide openings, with the guide rails passing through the guide openings to the left side of the positioning block.

[0012] In a preferred embodiment, brackets are installed on both sides of the left side of the positioning block, and the top of the brackets is fixedly connected to the bottom of the telescopic cylinder.

[0013] In a preferred embodiment, a connecting groove is provided at the bottom left side of the positioning block, and the output end of the telescopic cylinder is connected to the positioning block through the connecting groove.

[0014] In a preferred embodiment, the assembly groove is V-shaped and is used in conjunction with a positioning block and a retaining ring.

[0015] The heavy-duty bearing assembly fixture provided by this utility model has the following advantages:

[0016] 1. By setting up an assembly tooling mechanism, heavy bearings can be supported during tooling and an assembly thrust can be applied to the heavy bearings during the assembly process to connect the heavy bearings to the shaft. This allows workers to perform docking and force application assembly operations between the heavy bearings and the external shaft, avoiding situations where it is difficult to dock and apply force during the assembly of heavy bearings, which could easily lead to the assembly position not reaching the target position, affecting the accuracy and efficiency of the heavy bearing assembly. Therefore, the convenience and efficiency of the heavy bearing assembly operation are improved.

[0017] 2. By setting guide ports and guide rails, the positioning block can be moved and guided to prevent deviation. This ensures the movement direction of the positioning block and the heavy bearing when the telescopic cylinder pushes the positioning block to assemble the heavy bearing. It also prevents the positioning block from shifting when it is being used with the telescopic cylinder to apply force to assemble the heavy bearing, thus improving the working guidance of the positioning block.

[0018] 3. By setting up a bracket, the telescopic hydraulic cylinder can be supported and a medium can be provided for workers to connect the telescopic hydraulic cylinder to the external assembly table.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-4This utility model provides a technical solution: a heavy bearing assembly fixture, including a positioning block 1 and an assembly fixture mechanism. A heavy bearing 2 is installed on the top of the positioning block 1, and a telescopic hydraulic cylinder 3 is installed on the bottom left side of the positioning block 1. The cylinder can support the heavy bearing 2 during the fixture assembly and apply assembly thrust to the heavy bearing 2 during the assembly process, so that the heavy bearing 2 is connected to the shaft. This allows the operator to perform docking and force application assembly operations between the heavy bearing 2 and the external shaft, avoiding the situation where the heavy bearing 2 is difficult to dock and apply force during the assembly process, which could easily lead to the assembly position not reaching the target position, affecting the assembly accuracy and efficiency of the heavy bearing 2. Therefore, it improves the convenience and efficiency of the heavy bearing 2 assembly operation.

[0027] Reference Figures 1-4 In a preferred embodiment, the assembly tooling mechanism includes an assembly groove 4, which is located on the right side of the top of the positioning block 1. A retaining ring 5 is installed on the left side of the inner wall of the assembly groove 4. The heavy bearing 2 is located inside the assembly groove 4 and contacts the retaining ring 5. A receiving hole 6 is located on the left side of the inner wall of the assembly groove 4 and communicates with the retaining ring 5. The heavy bearing 2 is placed inside the assembly groove 4 and contacts the retaining ring 5. Since the assembly groove 4 is V-shaped, it can cooperate with the retaining ring 5 to provide position support and prevent rolling of the placed heavy bearing 2, ensuring the position of the heavy bearing 2 so that the positioning block 1 can drive the heavy bearing 2 to move for force application assembly work. Subsequently, the external shaft is moved to the right side of the heavy bearing 2 and aligned with the heavy bearing 2. Then, the telescopic hydraulic cylinder 3 applies a rightward moving thrust to the positioning block 1, so that the positioning block 1 cooperates with the assembly groove 4 and the retaining ring 5 to drive the heavy bearing 2 to move. When the bearing 2 moves to the right, the heavy bearing 2, under the influence of the rightward thrust of the positioning block 1, contacts and is fitted onto the outside of the pre-aligned shaft. Since the receiving hole 6 is connected to the retaining ring 5, as the heavy bearing 2 is installed on the outside of the shaft, the left side of the shaft passes through the retaining ring 5 and enters the receiving groove, so that the positioning block 1 can push the heavy bearing 2 to a suitable position on the shaft surface. Guide holes 7 are provided on both sides of the bottom of the positioning block 1. The guide rail 8 is movably connected inside the guide hole 7. The guide rail 8 passes through the guide hole 7 to the left side of the positioning block 1, which can guide the positioning block 1 to move and prevent it from deviating. This ensures the direction of movement of the positioning block 1 and the heavy bearing 2 when the telescopic cylinder 3 pushes the positioning block 1 to assemble the heavy bearing 2, and avoids the situation where the positioning block 1 moves and deviates when the telescopic cylinder 3 works with the positioning block 1 to assemble the heavy bearing 2, thus improving the working guidance of the positioning block 1.

[0028] Reference Figures 2-4In a preferred embodiment, brackets 9 are installed on both sides of the left side of the positioning block 1. The top of the brackets 9 is fixedly connected to the bottom of the telescopic cylinder 3, which can support the telescopic cylinder 3 and provide a medium for the operator to connect the telescopic cylinder 3 to the external assembly table. This avoids the situation where the telescopic cylinder 3 is difficult to support and connect to the external assembly table during use, thus improving the working support effect and installation convenience of the telescopic cylinder 3. A connecting groove 10 is provided at the bottom of the left side of the positioning block 1. The output end of the telescopic cylinder 3 is connected to the positioning block 1 through the connecting groove 10, which provides space for the telescopic cylinder 3 to be connected to the positioning block 1. This allows the user to perform the installation connection operation between the output end of the telescopic cylinder 3 and the positioning block 1, avoiding the situation where the telescopic cylinder 3 is difficult to connect to the positioning block 1 during use, thus improving the convenience of the installation connection between the telescopic cylinder 3 and the positioning block 1.

[0029] Reference Figures 2-4 In a preferred embodiment, by setting the assembly groove 4 in a V-shape, the assembly groove 4 is used in conjunction with the positioning block 1 and the retaining ring 5. It can support the heavy bearing 2 placed by the positioning block 1 during assembly to prevent rolling. This causes the assembly groove 4 to automatically calibrate the central axis of the heavy bearing 2 through geometric constraints, ensuring that the center of the heavy bearing 2 and the center of the shaft to be assembled are on the same straight line. This avoids the heavy bearing 2 rolling when the positioning block 1 moves the heavy bearing 2 through the assembly groove 4 for assembly, which would cause the heavy bearing 2 to deviate from the center of the shaft to be assembled. Therefore, the assembly support and restriction effect of the assembly groove 4 is improved.

[0030] Specifically, the working process or principle of this heavy-duty bearing assembly fixture is as follows: During use, the telescopic cylinder 3 is installed on the top of the external assembly table via the bracket 9. The positioning block 1 is then moved between the positioning block 1 and the external assembly table via the guide rail 8 and guide port 7. Next, the positioning block 1 and the output end of the telescopic cylinder 3 are connected via the connecting groove 10, preparing for the telescopic cylinder 3 to provide moving assembly force to the positioning block 1. Then, the heavy-duty bearing 2 to be installed is placed inside the assembly groove 4, and the heavy-duty bearing 2 contacts the retaining ring 5. Because the assembly groove 4 is V-shaped, it can cooperate with the retaining ring 5 to provide positional support and prevent rolling of the placed heavy-duty bearing 2, ensuring its position so that the positioning block 1 can move the heavy-duty bearing 2 for subsequent force application and assembly. Finally, the shaft of the heavy-duty bearing 2 to be assembled is moved to the right side of the heavy-duty bearing 2, and the shaft is aligned with the heavy-duty bearing 2. Alignment is achieved, and then the telescopic hydraulic cylinder 3 applies a rightward pushing force to the positioning block 1. At this time, the guide rail 8 moves inside the guide port 7, performing translational connection and guidance work between the positioning block 1 and the external assembly table during the movement process, ensuring that the movement of the positioning block 1 follows the preset trajectory. The positioning block 1, in conjunction with the assembly groove 4 and the retaining ring 5, drives the heavy bearing 2 to move to the right. At this time, the heavy bearing 2, affected by the rightward pushing force of the positioning block 1, contacts and is fitted onto the outside of the pre-aligned shaft. Since the receiving hole 6 is connected to the retaining ring 5, as the heavy bearing 2 is installed to the outside of the shaft, the left side of the shaft passes through the heavy bearing 2 and the retaining ring 5 into the receiving groove, allowing the positioning block 1 to pass through and accommodate the shaft during the installation of the heavy bearing 2. This prevents the shaft from being unable to pass through the positioning block 1 during installation, which would cause the positioning block 1 to be unable to push the heavy bearing 2 into place, so that the positioning block 1 can smoothly push the heavy bearing 2 to the appropriate position on the shaft surface.

[0031] It should be noted that the heavy-duty bearing 2 and the telescopic hydraulic cylinder 3 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
