Description

Technical Field

[0001] This utility model relates to the field of pressure ring technology, and in particular to a bearing-type pressure ring with built-in balls. Background Technology

[0002] In the field of mechanical assembly, the installation and fixing of bearings is a key step in ensuring the accuracy and stability of equipment operation.

[0003] Existing traditional pressure rings rely on manual adjustment of preload, which can easily lead to uneven axial load, causing bearing wear or excessive clearance, affecting rotational accuracy. Furthermore, it requires repeated disassembly and reassembly of bolts or the use of special tools (such as hydraulic nuts), which is time-consuming and labor-intensive, especially during mass assembly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of low operating efficiency in existing technologies by providing a bearing-type pressure ring with built-in balls.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bearing-type pressure ring with built-in ball bearings, comprising a base, an adjusting frame fixedly connected to the outer surface of the base, a knob provided on the outer surface of the adjusting frame, a bidirectional lead screw fixedly connected to the outer surface of the knob, a clamping plate sleeved on the outer surface of the bidirectional lead screw, the clamping plate being threadedly connected to the bidirectional lead screw, a first bearing fixedly connected to one end of the bidirectional lead screw, a support frame fixedly connected to the outer surface of the adjusting frame, a liquid pump fixedly connected to the outer surface of the support frame, a telescopic rod fixedly connected to the output end of the liquid pump, an electromagnet fixedly connected to one end of the telescopic rod, and a pressure plate provided on the outer surface of the electromagnet.

[0006] In a preferred embodiment, the outer surface of the base is provided with a sliding groove, the inner wall of the sliding groove is fixedly connected with a sliding rod, and a limit rod is sleeved on the outer surface of the sliding rod.

[0007] In a preferred embodiment, a spring is sleeved on the outer surface of the slide rod, one end of the spring is fixedly connected to the limiting rod, and the other end of the spring is fixedly connected to the slide groove.

[0008] In a preferred embodiment, the outer surface of the limiting rod is provided with a through hole that matches the slide rod, the through hole is slidably connected to the slide rod, and the limiting rod is slidably connected to the slide groove.

[0009] In a preferred embodiment, the outer surface of the adjustment frame is provided with a rectangular groove that matches the clamping plate, and the rectangular groove is slidably connected to the clamping plate.

[0010] In a preferred embodiment, the first bearing is placed inside the adjusting frame, and the first bearing is fixedly connected to the adjusting frame.

[0011] In a preferred embodiment, the outer surface of the base is provided with a bearing assembly.

[0012] In a preferred embodiment, the inner wall of the adjusting frame is provided with a rotating hole adapted to the bidirectional lead screw, and the rotating hole is rotatably connected to the bidirectional lead screw.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention provides a working environment for bearing assembly via a base. During assembly, the bearing assembly is first placed on the base. Then, by rotating a knob, a bidirectional lead screw is rotated inside the adjusting frame. The first bearing ensures smoother rotation of the bidirectional lead screw. Since the bidirectional lead screw is threadedly connected to the clamping plate, the clamping plate moves in opposite directions as the lead screw rotates. The movement of the clamping plate clamps and fixes the bearing assembly. Then, the electromagnet is energized to fix the pressure plate. Next, a hydraulic pump drives a telescopic rod to move, which in turn moves the electromagnet, thus assembling the pressure plate and the bearing assembly. After assembly, the power supply to the electromagnet is disconnected, separating the electromagnet from the pressure plate, thus completing the bearing assembly. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a bearing-type pressure ring with built-in ball bearings, including a base 1, an adjusting frame 2 fixedly connected to the outer surface of the base 1, a knob 4 on the outer surface of the adjusting frame 2, a bidirectional lead screw 5 fixedly connected to the outer surface of the knob 4, a rotating hole adapted to the bidirectional lead screw 5 on the inner wall of the adjusting frame 2, the rotating hole being rotatably connected to the bidirectional lead screw 5, a clamping plate 15 sleeved on the outer surface of the bidirectional lead screw 5, a rectangular groove adapted to the clamping plate 15 on the outer surface of the adjusting frame 2, the rectangular groove being slidably connected to the clamping plate 15, the clamping plate 15 being threadedly connected to the bidirectional lead screw 5, a first bearing 6 fixedly connected to one end of the bidirectional lead screw 5, the first bearing 6 being placed inside the adjusting frame 2, the first bearing 6 being fixedly connected to the adjusting frame 2, a support frame 3 fixedly connected to the outer surface of the adjusting frame 2, a liquid pump 7 fixedly connected to the outer surface of the support frame 3, a telescopic rod 8 fixedly connected to the output end of the liquid pump 7, an electromagnet 9 fixedly connected to one end of the telescopic rod 8, a pressure plate 10 on the outer surface of the electromagnet 9, and a bearing assembly on the outer surface of the base 1.

[0024] In this embodiment, the base 1 provides a working environment for bearing assembly. During assembly, the bearing assembly is first placed on the base 1. Then, the double-acting screw 5 is rotated inside the adjusting frame 2 by rotating the knob 4. The first bearing 6 ensures smoother rotation of the double-acting screw 5. Since the double-acting screw 5 is threadedly connected to the clamping plate 15, the clamping plate 15 moves in opposite directions as the double-acting screw 5 rotates. The movement of the clamping plate 15 clamps and fixes the bearing assembly. Then, the electromagnet 9 is energized to fix the pressure plate 10. Then, the hydraulic pump 7 drives the telescopic rod 8 to move. The movement of the telescopic rod 8 drives the electromagnet 9 to move, thereby assembling the pressure plate 10 with the bearing assembly. After assembly, the power supply to the electromagnet 9 is cut off to separate the electromagnet 9 from the pressure plate 10, thus completing the assembly of the bearing.

[0025] Example 2

[0026] like Figures 1-4As shown, a groove 11 is provided on the outer surface of the base 1. A slide rod 12 is fixedly connected to the inner wall of the groove 11. A limit rod 14 is sleeved on the outer surface of the slide rod 12. A spring 13 is sleeved on the outer surface of the slide rod 12. One end of the spring 13 is fixedly connected to the limit rod 14, and the other end of the spring 13 is fixedly connected to the groove 11. A through hole adapted to the slide rod 12 is provided on the outer surface of the limit rod 14. The through hole is slidably connected to the slide rod 12, and the limit rod 14 is slidably connected to the groove 11.

[0027] In this embodiment, during assembly, the limiting rod 14 is attached to the bearing assembly to limit the bearing assembly, ensuring that the pressure plate 10 can be assembled normally. Then, during assembly, the pressure plate 10 presses the limiting rod 14, causing the limiting rod 14 to move along the slide rod 12 into the slide groove 11. The movement of the limiting rod 14 presses the spring 13, putting the spring 13 into a compressed state. After the assembly is completed, the bearing is removed, and the spring 13 returns to its original position, thereby facilitating the limiting of the next bearing assembly and ensuring the normal progress of the assembly work.

[0028] Working principle:

[0029] like Figures 1-4 As shown, in this invention, firstly, the knob 4 is rotated, causing the bidirectional lead screw 5 to rotate within the rotating hole of the adjusting frame 2. The rotation of the bidirectional lead screw 5 causes the threaded clamping plate 15 to move along the rectangular groove on the adjusting frame 2, thus clamping and fixing the bearing assembly placed on the base 1. Simultaneously, the first bearing 6 ensures the smooth rotation of the bidirectional lead screw 5. Next, the electromagnet 9 is energized, attracting the pressure plate 10. The hydraulic pump 7 is then activated, pushing the telescopic rod 8 to move. The telescopic rod 8 moves the electromagnet 9 and the pressure plate 10 closer to the bearing assembly for assembly. During assembly, the pressure plate 10 presses against the limiting rod 14, which slides along the slide rod 12 within the slide groove 11, compressing the spring 13. After assembly, the power to the electromagnet 9 is cut off, separating the electromagnet 9 from the pressure plate 10, allowing the assembled bearing to be removed. At this point, the spring 13 rebounds, resetting the limiting rod 14 to limit the next bearing assembly to be assembled. This cycle repeats, achieving efficient bearing assembly. This bearing-type pressure ring design with built-in balls improves the efficiency and accuracy of bearing assembly through the coordinated work of various components, reduces the complexity of manual operation, and brings convenience to bearing assembly work. Moreover, the bearing assembly is compatible with the bearing assembly structure on the base 1, which can better ensure the accuracy and stability of the assembly, making the entire assembly process more reliable.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
