Description

Technical Field

[0001] This utility model relates to the field of bearing installation technology, specifically a bearing press-fitting device. Background Technology

[0002] Bearings are indispensable basic components in mechanical equipment. Their main function is to support rotating parts and reduce friction and wear during their movement. They typically consist of inner and outer rings, rolling elements (such as balls and rollers), and a cage. These components work together precisely to ensure efficient and smooth rotational motion. Depending on their structure and application, bearings can be classified into various types, such as deep groove ball bearings, tapered roller bearings, and thrust bearings, each with its own specific performance advantages.

[0003] Bearings are typically fixed to the housings of various mechanical equipment using specific bearing mounting slots. During installation, an interference fit is often required between the bearing and the mounting slot. This fit means the bearing is slightly larger than the slot, making it difficult to insert the bearing smoothly. To overcome this challenge, assembly workers often use a hammering method, forcing the bearing into the mounting slot through physical impact. However, while this method accomplishes the installation, it has a significant drawback: the hammering process can easily damage the bearing itself, affecting its performance and lifespan. Furthermore, hammering is relatively inefficient, and the entire installation process is time-consuming, which reduces production efficiency to some extent. Summary of the Invention

[0004] The purpose of this invention is to provide a bearing press-fitting device to solve the problem of slow bearing installation speed in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing press-fitting device, comprising a threaded sleeve, positioning sleeves fixedly installed on both sides of the threaded sleeve, a tensioning screw provided at the end of the positioning sleeve, a clamping jaw slidably installed inside the positioning sleeve, a press-fitting assembly provided inside the threaded sleeve, the press-fitting assembly comprising a press-fitting screw threadedly installed inside the threaded sleeve, an adjusting handle installed at the upper end of the press-fitting screw, a press-fitting plate rotatably installed at the lower end of the press-fitting screw, and a heating assembly provided on the press-fitting plate.

[0006] Preferably, a rotating hole is provided in the middle of the pressing plate, and an installation hole is provided on one side of the rotating hole on the pressing plate. A rotating connecting seat is provided between the pressing screw and the pressing plate, and an anti-slip pad is fixedly installed at the bottom of the pressing plate.

[0007] Preferably, the bottom of the pressing plate is provided with an installation groove, and the anti-slip pad is installed on the bottom of the pressing plate through the installation groove.

[0008] Preferably, the pressing plate is rotatably connected to the pressing screw via a rotating connecting seat, and a connecting hole is provided at the upper edge of the pressing screw. The adjusting handle is installed at the upper edge of the pressing screw through the connecting hole.

[0009] Preferably, the heating assembly includes a rotating seat rotatably mounted in a rotating hole, a gas nozzle fixedly mounted on the rotating seat, a rotary joint provided on the gas nozzle, a gas supply pipe connected to the rotary joint, a driven gear ring fixedly mounted on the gas nozzle, a drive motor fixedly mounted on the press plate, and a drive gear fixedly mounted at the output end of the drive motor.

[0010] Preferably, a portable butane gas cylinder is connected to the end of the gas pipeline.

[0011] Preferably, the rotating seat is rotatably mounted on the pressing plate through the rotating hole, the gas nozzle is rotatably mounted on the bottom of the pressing plate through the rotating seat, the output end of the drive motor passes through the pressing plate through the mounting hole, the drive gear is rotatably mounted on one side of the driven gear ring through the drive motor, and the drive gear meshes with the driven gear ring, and the gas delivery pipe is rotatably connected to the gas nozzle through a rotary joint.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, butane gas is injected and ignited through a gas nozzle, and the resulting flame heats the inner wall of the bearing mounting groove. This heating process triggers the start of the drive motor, which in turn drives the gear to rotate. As the drive gear rotates, the driven gear ring also rotates, ultimately causing the gas nozzle itself to rotate. This series of mechanical movements achieves uniform heating of the inner wall of the bearing mounting groove. Due to the effect of thermal expansion and contraction, the size of the bearing mounting groove is enlarged, thereby facilitating the installation of the bearing.

[0014] 2. After the size of the bearing mounting groove is enlarged in this application, the bearing can be placed at the upper end of the bearing mounting groove. Then, the pressing screw can be rotated downwards. After the pressing screw is rotated downwards, it will drive the pressing plate to move downwards. After the pressing plate moves downwards, it will quickly press the bearing into the bearing mounting groove. Attached Figure Description

[0020] 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.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a bearing press-fitting device, including a threaded sleeve 1, positioning sleeves 3 fixedly installed on both sides of the threaded sleeve 1, a tightening screw 2 provided at the end of the positioning sleeve 3, a clamping claw 4 slidably installed inside the positioning sleeve 3, a press-fitting assembly 5 provided inside the threaded sleeve 1, and a heating assembly 6 provided on the press-fitting plate 504. Through the cooperation of the press-fitting assembly 5 and the heating assembly 6, the bearing can be conveniently and quickly pressed into the bearing mounting groove.

[0022] like Figure 2 and Figure 3 As shown, the press-fit assembly 5 includes a press-fit screw 502 threadedly installed in a threaded sleeve 1. An adjustment handle 501 is installed at the upper end of the press-fit screw 502. A press-fit plate 504 is rotatably installed at the lower end of the press-fit screw 502. A rotating hole 506 is provided in the middle of the press-fit plate 504. An installation hole 507 is provided on one side of the rotating hole 506 on the press-fit plate 504. A rotating connecting seat 503 is provided between the press-fit screw 502 and the press-fit plate 504. An anti-slip pad 505 is fixedly installed at the bottom of the press-fit plate 504. An installation groove is provided at the bottom of the press-fit plate 504. The anti-slip pad 505 is installed at the bottom of the press-fit plate 504 through the installation groove.

[0023] Specifically, when butane gas is ejected through the gas nozzle 606, it can be ignited, and the resulting flame directly scorches the inner wall of the bearing mounting slot. During this process, the drive motor 603 can be activated. Once activated, the drive motor 603 begins operation, driving the connected drive gear 604 to rotate. The rotation of the drive gear 604 is transmitted to the driven gear ring 605, causing it to rotate as well. The rotation of the driven gear ring 605, in turn, drives the gas nozzle 606 to rotate accordingly. This continuous rotation ensures that the flame evenly heats the inner wall of the bearing mounting slot. Due to the physical principle of thermal expansion and contraction, the heated inner wall expands slightly, thus increasing the size of the bearing mounting slot. This expansion facilitates bearing installation, making it easier to place and secure the bearing in the appropriate position.

[0024] like Figure 2 and Figure 4 As shown, the heating assembly 6 includes a rotating seat 607 rotatably mounted in a rotating hole 506, a gas nozzle 606 fixedly mounted on the rotating seat 607, a rotary joint 602 provided on the gas nozzle 606, a gas supply pipe 601 connected to the rotary joint 602, a driven gear ring 605 fixedly mounted on the gas nozzle 606, a drive motor 603 fixedly mounted on the press plate 504, a drive gear 604 fixedly mounted at the output end of the drive motor 603, and a portable butane gas cylinder connected to the end of the gas supply pipe 601.

[0025] Specifically, the user can place the bearing at the upper end of the bearing mounting slot and then rotate it downwards to start the pressing screw 502 rotating. As the pressing screw 502 rotates downwards, it drives the pressing plate 504 to move downwards as well. With the downward movement of the pressing plate 504, the bearing will be quickly pressed into the bearing mounting slot.

[0026] Working Principle: First, loosen the tension screw 2. After loosening the tension screw 2, adjust the opening angle of the clamping jaws 4 to clamp them onto the equipment housing. Align the pressure plate 504 with the bearing mounting groove. After aligning the pressure plate 504 with the bearing mounting groove, rotate the adjusting handle 501 downwards to insert the gas nozzle 606 into the bearing mounting groove. Then, connect the end of the gas pipeline 601 to the portable butane gas cylinder. After connecting the end of the gas pipeline 601 to the portable butane gas cylinder, open the valve on the portable butane gas cylinder to allow butane gas to be ejected through the gas nozzle 606. The butane gas ejected through the gas nozzle 606 can be ignited. The flame will scorch the inner wall of the bearing mounting groove, and the operation will be activated when the flame scorches the inner wall of the bearing mounting groove. The drive motor 603 is started, which drives the drive gear 604 to rotate. The drive gear 604 rotates, which in turn drives the driven gear ring 605 to rotate. The driven gear ring 605 rotates, which in turn drives the gas nozzle 606 to rotate, thereby uniformly heating the inner wall of the bearing mounting groove. Under the action of thermal expansion and contraction, the bearing mounting groove expands. Then, the pressing screw 502 can be rotated upward to make the gas nozzle 606 exit the bearing mounting groove. After the gas nozzle 606 exits the bearing mounting groove, the bearing can be placed at the upper end of the bearing mounting groove. Then, the pressing screw 502 can be rotated downward. After the pressing screw 502 is rotated downward, it drives the pressing plate 504 to move downward. After the pressing plate 504 moves downward, it quickly presses the bearing into the bearing mounting groove.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
