Description

Technical Field

[0001] This utility model relates to the field of bearing press fitting, and in particular to an automatic bearing press fitting production device. Background Technology

[0002] Bearings are key components in modern machinery, primarily used to support rotating parts, reduce friction during movement, and ensure rotational accuracy. In servo press applications, bearing press-fitting is one of the most common and practical operations. The quality of press-fitting directly affects the performance and lifespan of vehicles or other equipment. Although bearings themselves are moving parts, their proper installation is crucial for ensuring the functionality of the entire system.

[0003] Press fitting technology refers to a method used in mechanical manufacturing to assemble cylindrical interference-fit mating parts (such as shafts and bearings). An interference fit refers to a mating where the inner ring diameter is slightly larger than the diameter of the shaft being fitted, or the outer ring diameter is slightly smaller than the corresponding hole diameter, resulting in a tight connection. The key to this type of assembly is applying a sufficiently large thrust to overcome the resistance caused by the interference fit, allowing the parts to be smoothly assembled, ensuring stability and precision. Using appropriate press fitting techniques and equipment, such as servo presses, can effectively improve product reliability and durability. However, it requires manual assembly of parts placed under the servo press; slow operation or errors can easily lead to physical injury to workers and affect product quality.

[0004] To address the above issues, it is necessary to design an automated bearing press-fitting production device. Utility Model Content

The press-fitting machine is fixedly connected to the top of the base and is located above the center end. The controller is fixedly connected to the front side of the press-fitting machine. Rotating shafts are rotatably connected to both the front and rear sides of the middle of the base. The two rotating shafts are equipped with conveyor belts, on which bearing components are placed. A servo motor is fixedly connected to the right side of the front part of the base. The output shaft of the servo motor is fixedly connected to the right side of the front rotating shaft. An electric slide rail is fixedly connected to the top of the base. The press-fitting machine, the servo motor, and the electric slide rail are electrically connected to the controller. The electric slide rail is located below and behind the press-fitting machine. A sliding disc is slidably connected to the front side of the electric slide rail. The sliding disc is located directly below the press-fitting machine. Two slots are opened on the left and right sides of the sliding disc. Four retaining balls are slidably connected around the inner perimeter of the two slots of the sliding disc.

[0010] In addition, it is particularly preferred that the base also includes a feeding rack, with feeding racks fixedly connected to both the left and right sides of the center.

[0011] In addition, it is particularly preferred that the base also includes a material control box, a stop block and a second elastic element.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] Example: An automatic bearing press-fitting production device, such as Figures 1-4As shown, the device includes a base 1, a pressing machine 2, a controller 3, a rotating shaft 4, a conveyor belt 5, a servo motor 6, an electric slide rail 10, a sliding plate 11, a retaining ball 13, and a first elastic element 14. The pressing machine 2 is bolted to the top of the base 1 and is located above the center end. The controller 3 is installed on the front side of the pressing machine 2. The rotating shaft 4 is rotatably connected to both the front and rear sides of the middle of the base 1. The two rotating shafts 4 are equipped with conveyor belts 5, and bearing components 9 are placed on the conveyor belts 5. The servo motor 6 is installed on the front right side of the base 1. The output shaft of the servo motor 6 is connected to... The rotating shaft 4 on the front side is fixedly connected to the right side. The electric slide rail 10 is bolted to the top of the base 1. The press machine 2, servo motor 6 and electric slide rail 10 are electrically connected to the controller 3. The electric slide rail 10 is located below the rear side of the press machine 2. A sliding plate 11 is slidably connected to the front side of the electric slide rail 10. The sliding plate 11 is located directly below the press machine 2. Two slots are opened on the left and right sides of the sliding plate 11. Four locking beads 13 are slidably connected to the inner sides of the two slots of the sliding plate 11. A first elastic element 14 is fixedly connected between the locking beads 13 and the sliding plate 11.

[0023] like Figure 1 and Figure 2 As shown, it also includes a baffle frame 7. The baffle frame 7 is fixedly connected to both sides of the conveyor belt 5. The baffle frame 7 plays a limiting role according to the size of the bearing component 9.

[0024] like Figure 1 and Figure 2 As shown, it also includes push blocks 8. Multiple push blocks 8 are provided on the conveyor belt 5. The push blocks 8 play a positioning role according to the size of the bearing component 9.

[0025] like Figure 2 and Figure 3 As shown, it also includes limit frames 12. Two limit frames 12 are fixedly connected to the top of the sliding disk 11. The two limit frames 12 correspond to the two slots on the sliding disk 11, and the limit frames 12 are located directly above the slots.

[0026] like Figure 1 and Figure 4 As shown, it also includes a feeding rack 15, and the feeding rack 15 is bolted to both the left and right sides of the middle part of the base 1.

[0027] like Figure 1 and Figure 4 As shown, it also includes a material control box 16, a stop block 17, and a second elastic element 18. The material control box 16 is fixedly connected to both the left and right sides of the middle of the base 1. The two material control boxes 16 are located in the direction away from the center end of the two material feeding racks 15. The stop block 17 is slidably connected to the left side of the inside of the material control box 16. The second elastic element 18 is fixedly connected between the left side of the inside of the material control box 16 and the left side of the stop block 17. The stop block 17 is located directly below the material feeding rack 15.

[0028] When it is necessary to press-fit the bearing component 9, first place the bearing component 9 on the conveyor belt 5. Because the conveyor belt 5 is equipped with a baffle 7 and a pusher 8, it has a limiting and positioning effect on the bearing component 9, making the subsequent pressing position more accurate. Then, put the other two parts into the feeding racks 15 on the left and right sides respectively.

[0029] Then, the servo motor 6 and the electric slide rail 10 are started by the controller 3. The servo motor 6 moves the bearing component 9 backward via the conveyor belt 5 and stops when it moves directly below the press machine 2. The electric slide rail 10 drives the sliding plate 11 to move to the left below the left feeding rack 15, so that the left groove of the sliding plate 11 is aligned with the discharge port below the feeding rack 15. At the same time, the stop block 17 is pressed to the left by the limit frame 12 on the sliding plate 11 and moves into the control box 16. The corresponding second elastic element 18 on the left is pressed. As the material is compressed, the parts in the feeding rack 15 fall into the sliding plate 11 through the limiting frame 12 and are held in place by four retaining balls 13. Then, the electric slide rail 10 drives the sliding plate 11 to move to the right below the pressing machine 2, aligning the pressing machine 2 with the left slot of the sliding plate 11, allowing the parts to be brought between the electric slide rail 10 and the bearing component 9. At the same time, the stop block 17 is no longer squeezed by the limiting frame 12 on the sliding plate 11, and the corresponding second elastic element 18 on the left stretches, causing the stop block 17 to move to the left below the feeding rack 15, stopping it again. The material is fed into the discharge port below the feeding rack 15, enabling automated feeding and making operation more convenient. The press machine 2 is started by the controller 3. The press machine 2 compresses the parts in the slot on the left side of the sliding plate 11 and the bearing component 9 on the conveyor belt 5 downwards, pressing the parts and bearing component 9 together. At the same time as the pressing is combined, the four corresponding retaining balls 13 are squeezed and moved away from the center end, and the first elastic element 14 is compressed. After the pressing is combined, the first elastic element 14 stretches and drives the retaining balls 13 to return to the center end. Then, the electric slide rail 10 is started by the controller 3 to move the sliding plate 11 to the right, bringing the parts on the right side between the electric slide rail 10 and the bearing component 9. The press machine 2 is started by the controller 3, and it compresses the parts in the slot on the right side of the sliding plate 11 and the bearing component 9 on the conveyor belt 5 downwards, pressing the parts and bearing component 9 together, completing the pressing combination of the bearing. There is no need for manual placement of the parts combination under the servo press, reducing safety hazards and increasing safety.

[0030] Place the container below the rear of the conveyor belt 5, and then start the servo motor 6 through the controller 3. The servo motor 6 will transport the press-fitted bearing to the container behind the conveyor belt 5. Then turn off the servo motor 6. If the bearing component 9 needs to be press-fitted again, repeat the above operation.

[0031] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
