Description

Technical Field

[0001] This utility model relates to the field of electrical component assembly equipment technology, and in particular to an electrical component bearing press-fitting equipment. Background Technology

[0002] Electrical component bearing press-fitting equipment is a specialized device used to precisely install bearings onto the shaft system of electrical components. Bearings are key support components of electrical components, and their press-fitting quality directly affects the operating accuracy, noise, lifespan, and reliability of electrical components. With the rapid development of industrial automation, smart home appliances, and new energy vehicles, electrical components are showing a trend towards miniaturization, high precision, and high load capacity.

[0003] The positioning components of existing devices are mostly of fixed size. For example, the diameter of the positioning boss of the pressure head is not adjustable, and the clamping mechanism can only be adapted to a single specification of bearing. When dealing with bearings of different inner or outer diameters, it is necessary to replace the entire pressure head, positioning seat and other core components. Not only is the replacement process cumbersome and requires the disassembly of multiple bolts, but it also requires the storage of a large number of special molds, which increases inventory costs. For multi-variety, small-batch production, frequent model changes will increase equipment downtime and affect production efficiency. Utility Model Content

[0005] To solve the above technical problems, this utility model provides the following technical solution: an electrical component bearing press-fitting device, including a machine body, a processing table on the inner wall of the machine body, a placement table fixedly connected to the bottom end of the processing table, a rotating plate slidably connected to the inner wall of the placement table, a plurality of evenly distributed rectangular blocks slidably connected to the inner wall of the placement table, protrusions at the bottom of the rectangular blocks slidably connected to the inner wall of the rotating plate, the placement table being located above the rotating plate, an axial through hole being opened in the middle of the rotating plate, the central part of the placement table extending downward through the axial through hole of the rotating plate and fixedly connected to the bottom end of the processing table, a fitting block slidably connected to the top end of the rectangular blocks and slidably connected to the inner wall of the placement table, a plurality of evenly distributed arc-shaped plates slidably connected to the top end of the placement table, a moving block slidably connected to the bottom end of the arc-shaped plates, and a pin slidably connected to the top end of the rotating plate and engaging with the top end of the processing table.

[0006] As a preferred embodiment of the bearing press-fitting equipment for electrical components of this utility model, the top of the processing table is provided with multiple insertion holes, the inner wall of the insertion hole is slidably connected to the outer wall of the pin, a return spring is sleeved on the outer wall of the pin, and a pull ring is fixedly connected to the top of the pin.

[0007] As a preferred embodiment of the bearing press-fitting equipment for electrical components of this utility model, the top of the rotating plate is provided with a plurality of arc-shaped holes that are slidably connected to the bottom outer wall of the rectangular block, and the two ends of the outer wall of the arc-shaped holes are fitted with guide rods that are fixedly connected to the inner wall of the placement platform.

[0008] As a preferred embodiment of the bearing press-fitting equipment for electrical components of this utility model, a micro motor is installed on the outer wall of the placement platform, and a lead screw that is threadedly connected to the inner wall of one of the moving blocks is fixedly connected to the output end of the micro motor. A rack is fixedly connected to the outer wall of the moving block, and a toothed ring that is rotatably connected to the inner wall of the placement platform is engaged with the outer wall of the rack.

[0009] As a preferred embodiment of the bearing press-fitting equipment for electrical components of this utility model, the inner wall of the placement platform is fixedly connected to two cylinders, the outer wall of the cylinders is slidably connected to the inner wall of the other two moving blocks, and the top of the moving blocks is provided with a moving groove that is slidably connected to the bottom end of the arc plate.

[0011] The beneficial effects of this utility model are: 1. By pulling the pin to retract the return spring, rotating the rotating plate will move the rectangular block along the guide rod, thus allowing the fitting block to fit tightly against the inner wall of the bearing. At the same time, driven by a micro motor, the fitting state between the arc plate and the outer wall of the bearing can be easily adjusted through the linkage of the lead screw, rack, and gear ring. The process does not require disassembling any parts; only simple pulling and rotating actions are needed to complete the positioning and adaptation of the bearing's inner wall.

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0021] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a bearing press-fitting device for electrical components, including a body 1. A processing table is provided on the inner wall of the body 1. A placement table 4 is fixedly connected to the bottom end of the processing table. A rotating plate 6 is slidably connected to the inner wall of the placement table 4. A plurality of evenly distributed rectangular blocks 11 are slidably connected to the inner wall of the placement table 4. The protrusions at the bottom of the rectangular blocks 11 are slidably connected to the inner wall of the rotating plate 6. The placement table 4 is located above the rotating plate 6. An axial through hole is provided in the middle of the rotating plate 6. The central part of the placement table 4 extends downward through the axial through hole of the rotating plate 6 and is fixedly connected to the bottom end of the processing table. A fitting block 8 is fixedly connected to the top end of the rectangular blocks 11 and is slidably connected to the inner wall of the placement table 4. A plurality of evenly distributed arc-shaped plates 9 are slidably connected to the top end of the arc-shaped plates 9. A moving block 13 is slidably connected to the bottom end of the arc-shaped plates 9. A pin 7 that engages with the top end of the processing table is slidably connected to the top end of the rotating plate 6.

[0022] The top of the processing table has multiple insertion holes 5. The inner wall of the insertion hole 5 is slidably connected to the outer wall of the pin 7. A return spring 17 is sleeved on the outer wall of the pin 7. A pull ring is fixedly connected to the top of the pin 7.

[0023] The top of the rotating plate 6 has multiple arc-shaped holes 10 that are slidably connected to the bottom outer wall of the rectangular block 11. Both ends of the outer wall of the arc-shaped holes 10 are fitted with guide rods 12 that are fixedly connected to the inner wall of the placement platform 4.

[0024] During use, when it is necessary to fit the fitting block 8 against the inner wall of the bearing, the operator first pulls the pull ring at the top of the pin 7 upwards. The pin 7 slides upwards along the inner wall of the rotating plate 6, and the return spring 17 sleeved on its outer wall is squeezed and contracted. At this time, the bottom end of the pin 7 disengages from the insertion hole 5 opened at the top of the processing table, releasing the fixation restriction on the rotating plate 6.

[0025] Rotating plate 6, because the top of rotating plate 6 has multiple arc-shaped holes 10, and the bottom outer wall of rectangular block 11 is slidably connected to the arc-shaped holes 10, and rectangular block 11 is also sleeved on guide rod 12 which is fixedly connected to the inner wall of placement platform 4, during the rotation of rotating plate 6, the inner wall of arc-shaped holes 10 pushes the sliding part of bottom of rectangular block 11.

[0026] Under the guidance of the thrust and the guide rod 12, the rectangular block 11 moves along the guide rod 12 toward the center of the placement platform 4, and the bonding block 8 fixedly connected to the top of the rectangular block 11 also moves synchronously until the bonding block 8 is tightly bonded to the inner wall of the bearing. After the bonding is completed, the pull ring is released, the return spring 17 returns to its original state and pushes the pin 7 to slide downward. The bottom end of the pin 7 is inserted into the corresponding insertion hole 5, and the rotating plate 6 is fixed again, so that the bonding block 8 remains in contact with the inner wall of the bearing. Example 2

[0027] Reference Figure 1 , Figure 2 , Figure 5 and Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a micro motor is installed on the outer wall of the placement platform 4, and the output end of the micro motor is fixedly connected to a lead screw 18 that is threadedly connected to the inner wall of one of the moving blocks 13. A rack 15 is fixedly connected to the outer wall of the moving block 13, and a toothed ring 16 that is rotatably connected to the inner wall of the placement platform 4 is engaged with the outer wall of the rack 15.

[0028] The inner wall of the placement platform 4 is fixedly connected to two cylinders 19. The outer wall of the cylinders 19 is slidably connected to the inner wall of the other two moving blocks 13. The top of the moving block 13 is provided with a moving groove 14 that is slidably connected to the bottom of the arc plate 9.

[0029] A pressure plate 2 is slidably connected to the top of the processing table, and multiple guide posts 3 are slidably connected to the inner wall of the pressure plate 2 and fixedly connected to the bottom of the processing table.

[0030] During use, when it is necessary to adjust the position of the arc plate 9 to adapt to the bearing outer wall of different sizes, the micro motor installed on the outer wall of the placement platform 4 is started. The output end of the micro motor drives the lead screw 18 to rotate. The moving block 13, which is threadedly connected to the lead screw 18, is rectangular in shape and cannot rotate due to the space limitation of the inner wall of the placement platform 4. Therefore, it will move along the axial direction of the lead screw 18 under the drive of the lead screw 18. The rack 15, which is fixedly connected to the outer wall of the movable block 13, also moves accordingly. The rack 15 meshes with the toothed ring 16. The movement of the rack 15 causes the toothed ring 16 to rotate on the inner wall of the placement platform 4. The remaining movable blocks 13 are fitted onto the cylinder 19, which is fixedly connected to the inner wall of the placement platform 4, and are meshed with the toothed ring 16. Driven by the toothed ring 16, these movable blocks 13 will move synchronously along the cylinder 19. Since the top of the movable block 13 is provided with a movable groove 14, and the bottom of the arc plate 9 is slidably connected to the movable groove 14, when the movable block 13 moves, it will drive the arc plate 9 to slide on the top of the placement platform 4 through the movable groove 14. Multiple arc plates 9 move synchronously, which can adjust the distance between them, thereby adapting to the outer wall of bearings of different sizes and achieving stable clamping of the bearings.

[0031] The remaining structure is the same as that in Example 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
