[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-5As shown, this utility model proposes a bearing hot press for assembling a rotor 100 and a stator 200 into a bearing. The bearing hot press includes a platform 300, a mounting base 400, a heating module 500, and a pressing module 600. The mounting base 400 is mounted on the upper surface of the platform 300 and is used to mount the rotor 100. The heating module 500 is mounted on the lower surface of the platform 300 and is used to extend from below the mounting base 400 into the rotor 100 and to heat the inner ring of the rotor 100. The pressing module 600 is mounted on the mounting base 400 and placed above the rotor 100. The pressing module 600 is used to mount the stator 200 and assemble the stator 200 onto the rotor 100.

[0029] In this embodiment, the specific implementation method is as follows: using manual labor or an external robotic arm or similar mobile device, the rotor 100 and stator 200 are placed on the mounting base 400 and the pressing module 600, respectively. At this time, the rotor 100 and stator 200 are separated, on the same vertical line, and maintain a certain distance. The heating module 500 is activated, extending from below the mounting base 400 into the inner ring of the rotor 100 to heat the inner ring. After reaching a certain temperature, the heating module 500 is withdrawn from the inner ring of the rotor 100. At this time, the pressing module 600 is activated and the stator 200 is assembled onto the rotor 100 to obtain the bearing product. The heating and assembly functions are integrated into one device, realizing integrated heating and assembly, achieving automatic heating and assembly of the bearing, improving assembly and production efficiency, and reducing labor costs.

[0030] In one embodiment of this application, the mounting base 400 includes a base 401 and a frame 402. The base 401 is fixedly connected to the platform 300. A lower mold fixture 4011 is provided on the base 401, and a through hole 4012 is provided on the lower mold fixture 4011. The frame 402 is mounted on the base 401, and a pressing module 600 is fixedly connected to the frame 402. The rotor 100 is mounted on the lower mold fixture 4011, and the inner ring of the rotor 100 is coaxial with the through hole 4012. The heating module 500 is used to extend out of the through hole 4012 and heat the inner ring of the rotor 100.

[0031] See appendix Figure 2It should be noted that the lower mold fixture 4011 is used to position the rotor 100, abut against the outer periphery of the inner ring of the rotor 100, and to elevate the rotor 100 so that there are no other structures interfering with the outer periphery of the rotor 100, so that the subsequent pressing module 600 can directly press the stator 200 onto the rotor 100. At the same time, the through hole 4012 is set at the position of the lower mold fixture 4011, which is exactly opposite to the shaft hole of the rotor 100. The through hole 4012 penetrates the lower mold fixture 4011 and connects to the lower surface of the platform 300, so that the heating module 500 can enter through the through hole 4012 and heat the inner ring of the rotor 100.

[0032] It should be added that the stator 200 has an annular housing that encloses the rotor 100, and a shaft is provided at its center. This shaft is used to be nested in the inner ring of the rotor 100. Therefore, the through hole 4012 mentioned above also provides assembly space for the stator 200.

[0033] In one embodiment of this application, the heating module 500 includes a fixing frame 501, a first driving member 502, and a hot air gun 503. The fixing frame 501 is mounted on the lower surface of the platform 300, the first driving member 502 is fixedly connected to the fixing frame 501, the hot air gun 503 is drivenly connected to the first driving member 502, and under the drive of the first driving member 502, the end of the hot air gun 503 extends into the through hole 4012.

[0034] In one embodiment of this application, the heating module 500 further includes a first sensor 504, which is fixedly connected to the mounting bracket 501 and is used to detect the driving stroke of the first driving member 502.

[0035] It should be noted that the first driving component 502 includes, but is not limited to, a telescopic cylinder and a linear motor, etc., driving structures used to drive the hot air gun 503 to extend into or out of the through hole 4012. In a specific embodiment, when the rotor 100 is placed on the lower mold fixture 4011, the first driving component 502 is activated and drives the hot air port of the hot air gun 503 to extend out from the through hole 4012 and be placed inside the inner ring of the rotor 100. The hot air gun 503 begins to heat the inner ring. After the heating work is completed, the first driving component 502 drives the hot air gun 503 to return along the original path. The first sensor 504 detects the driving stroke of the hot air gun 503 to avoid the movement distance being too long or too short, which would affect the heating effect of the inner ring of the rotor 100.

[0036] In one embodiment of this application, the press-fit module 600 includes a second drive member 601, a guide plate 602, and an upper mold fixture 603. The second drive member 601 is fixedly connected to the frame 402 and positioned above the lower mold fixture 4011. The guide plate 602 is fixedly connected to the drive end of the second drive member 601. The upper mold fixture 603 is used to install the stator 200 and is installed on the guide plate 602. Under the drive of the second drive member 601, the upper mold fixture 603 approaches the lower mold fixture 4011 and assembles the stator 200 and the rotor 100.

[0037] The upper mold fixture 603 is equipped with multiple magnets 6031 and positioning posts.

[0038] It should be noted that the second driving component 601 includes, but is not limited to, a telescopic cylinder and a linear motor, etc., used to drive the guide plate 502 and the upper mold fixture 603 to move closer to or away from the base 401. Since the stator 200 is made of metal, it can be magnetically attracted by the magnet 6031 on the upper mold fixture 603. However, since the stator 200 is installed on the upper mold fixture 603, it cannot be guaranteed that it will be able to press-fit later. The position of the stator 200 corresponds exactly to the position of the rotor 100. Since the shaft on the stator 200 is hollow, a positioning post is also provided on the upper mold fixture 603. When the stator 200 is installed on the upper mold fixture 603 through the magnet 6031, its hollow shaft will be sleeved on the positioning post to achieve quick positioning. This facilitates the quick installation of the stator 200 onto the upper mold fixture 603 while ensuring the normal operation of the subsequent press-fit.

[0039] In one embodiment of this application, the press-fit module 600 further includes a second sensor 604, which is connected between the second drive member 601 and the guide plate 602 and is used to detect the pressure value during assembly.

[0040] The press-fit module 600 also includes multiple guide posts 605, each of which is vertically fixed on the base 401 and slidably connected to the guide plate 602.

[0041] The press-fit module 600 also includes multiple elastic elements 606, each elastic element 606 being sleeved on a corresponding guide post 605.

[0042] It should be noted that the elastic element 606 is specifically a helical spring, which is sleeved on the guide post 605. During the press-fitting operation, the guide plate 602 will come into contact with the elastic element 606. During this period, the second sensor 604 will detect the pressure value of the current press-fitting operation to avoid excessive pressure, which could damage the stator 200 and rotor 100 during the press-fitting operation. The elastic element 606 also plays a buffering role, further preventing excessive pressure on the stator 200 and rotor 100.

[0043] In one embodiment of this application, the bearing hot press further includes a third sensor 700, which is mounted on the frame 402 and used to detect the heating temperature of the heating module 500.

[0044] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
