Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, and in particular to a bearing ring lifting carrier. Background Technology

[0002] Lifting carriers for bearing races are mainly used to facilitate the handling and installation of races during bearing production and maintenance. Traditional manual lifting methods have problems such as inconvenience, low efficiency, and safety hazards. With the improvement of industrial automation, lifting carriers with high efficiency, low energy consumption, convenient operation, and high safety have been designed to improve production efficiency and reduce labor intensity.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing bearing ring lifting carriers cannot achieve efficient and stable lifting of bearing rings. The inefficient lifting of the carrier will increase the handling and positioning time of the bearing rings. Especially in automated production lines, the delay of a single link will directly affect the overall production cycle and reduce the throughput of the production line. Inaccurate positioning of the carrier may cause the bearing ring installation position to be offset, affecting the accuracy of subsequent processing or assembly. Unstable lifting of the carrier may cause the bearing ring to fall or slip accidentally, threatening the safety of operators. The risk is even higher in high-speed automated production lines.

[0004] Therefore, this utility model proposes a lifting carrier for bearing rings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a lifting carrier for bearing rings.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a lifting carrier for bearing rings, including a base plate, and further comprising:

[0007] A lifting assembly includes a support base connected to a base plate, a first drive motor mounted on the base plate, a worm gear connected to the output end of the first drive motor, a worm wheel meshing on the worm gear, a first screw connected to the worm wheel, the first screw being rotatably connected inside the support base, a movable block threadedly connected to the first screw, and a support plate connected to the movable block;

[0008] The support assembly includes a counterweight block connected to one side of a base plate. A second drive motor is mounted on the base plate. A gear is connected to the output end of the second drive motor. A rack meshes with the gear. A support frame is connected to the rack. A second screw is threaded onto the support frame. A base is provided at the bottom of the second screw.

[0009] Furthermore, a slider is connected to the movable block, and a limit block is connected to the side of the support base near the slider, with the slider slidably connected to the limit block.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the slider on the moving block is slidably connected to the limiting block of the support seat. When the first screw drives the moving block to rise and fall, the slider slides along the guide groove of the limiting block, restricting the moving block to only move in the vertical direction, avoiding deviation or shaking during the lifting and lowering process, ensuring that the support plate rises and falls smoothly, and providing a stable bearing platform for the bearing ring.

[0011] Furthermore, the support plate is provided with a positioning component, which includes an electric push rod installed on one side of the bottom of the support plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that after the electric push rod installed at the bottom of the support plate is energized, the second rotating block connected to it is pushed by the extension and retraction of the electric push rod.

[0013] Furthermore, a support block is connected to the support plate, and a first rotating block is rotatably connected to the support block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by moving the second rotating block, the first rotating block, which is rotatably connected to the support block, is driven to rotate, so that the first rotating block can position bearing rings of different sizes.

[0015] Furthermore, a second rotating block is rotatably connected to the first rotating block, and the second rotating block is rotatably connected to the output end of the electric push rod.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the electric push rod extends or retracts, the second rotating block rotates under the action of the push rod, and at the same time drives the first rotating block to rotate around the support block, ensuring that the bearing ring is accurately positioned on the support plate.

[0017] Furthermore, a placement box is connected to the side of the support plate near the first rotating block.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the placement box on the support plate is used to place the bearing ring to be lifted, and the bearing ring is stably placed on the support plate through the cooperation of the first rotating block and the placement box.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when the bearing ring lifting carrier is in operation, the first drive motor drives the worm to rotate. Through the meshing transmission between the worm and the worm wheel, the first screw rotates, causing the moving block threaded onto the first screw to move along the screw axial direction. This, in turn, causes the support plate to rise or fall, completing the lifting operation of the bearing ring. The second drive motor of the support assembly drives the gear to rotate, and the rack meshing with the gear moves the support frame horizontally to a predetermined position. By rotating the second screw, the base can contact the ground to form a stable support. The counterweight improves the stability of the carrier by balancing the center of gravity, thus achieving efficient and stable lifting of the bearing ring. Attached Figure Description

[0031] 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.

[0032] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a lifting carrier for bearing rings, including a base plate 1, and further including:

[0033] The lifting assembly 2 includes a support base 21 connected to the base plate 1. A first drive motor 22 is installed on the base plate 1. A worm gear 23 is connected to the output end of the first drive motor 22. A worm wheel 24 meshes with the worm gear 23. A first screw 25 is connected to the worm wheel 24. The first screw 25 is rotatably connected to the support base 21. A moving block 26 is threadedly connected to the first screw 25. A support plate 29 is connected to the moving block 26.

[0034] Support assembly 3 includes a counterweight 31 connected to one side of base plate 1. A second drive motor 32 is mounted on base plate 1. A gear 33 is connected to the output end of the second drive motor 32. A rack 34 meshes with the gear 32. A support frame 35 is connected to the rack 34. A second screw 36 is threaded onto the support frame 35. A base 37 is provided at the bottom of the second screw 36. When the bearing ring lifting carrier is working, the first drive motor 22 drives the worm gear 23 to rotate. Through the meshing transmission between the worm gear 23 and the worm wheel 24, the first screw 25 is driven. Rotation causes the movable block 26, threadedly connected to the first screw 25, to move along the screw axis, thereby driving the support plate 29 to rise or fall, completing the lifting operation of the bearing ring. The second transmission motor 32 of the support assembly 3 drives the gear 33 to rotate, and the rack 34 meshing with the gear 33 drives the support frame 35 to move horizontally to a predetermined position. By rotating the second screw 36, the base 37 can contact the ground to form a stable support. The counterweight 31 improves the stability of the carrier by balancing the center of gravity, thus realizing the efficient and stable lifting operation of the bearing ring.

[0035] The above solutions also have the problem that, when the bearing rings need to be lifted, the bearing rings cannot be stably placed on the support plate 29. Figure 1 - Figure 2As shown: A slider 27 is connected to the movable block 26, and a limit block 28 is connected to the side of the support base 21 near the slider 27. The slider 27 is slidably connected to the limit block 28. The slider 27 on the movable block 26 is slidably connected to the limit block 28 of the support base 21. When the first screw 25 drives the movable block 26 to rise and fall, the slider 27 slides along the guide groove of the limit block 28, restricting the movable block 26 to only move in the vertical direction, avoiding its deviation or shaking during the rising and falling process, ensuring that the support plate 29 rises and falls smoothly, and providing a stable bearing platform for the bearing ring.

[0036] like Figure 1 as well as Figure 5 As shown, a positioning assembly 4 is provided on the support plate 29. The positioning assembly 4 includes an electric push rod 41 installed on one side of the bottom of the support plate 29. When the electric push rod 41 is energized, its extension and retraction pushes the second rotating block 44 connected to it. A support block 42 is connected to the support plate 29, and a first rotating block 43 is rotatably connected to the support block 42. The movement of the second rotating block 44 causes the first rotating block 43, which is rotatably connected to the support block 42, to rotate, so that the first rotating block 43 can position bearing rings of different sizes. A second rotating block 44 is rotatably connected to block 43. The second rotating block 44 is rotatably connected to the output end of the electric push rod 41. When the electric push rod 41 extends or retracts, the second rotating block 44 rotates under the action of the push rod, and at the same time drives the first rotating block 43 to rotate around the support block 42, ensuring that the bearing ring is accurately positioned on the support plate 29. A placement box 45 is connected to the side of the support plate 29 near the first rotating block 43. The placement box 45 on the support plate 29 is used to place the bearing ring to be lifted. Through the cooperation of the first rotating block 43 and the placement box 45, the bearing ring is stably placed on the support plate 29.

[0037] like Figure 1 - Figure 5As shown, before the bearing ring lifting operation begins, the second drive motor 32 first operates, driving the gear 33 to rotate. The rack 34, meshing with the gear 33, moves the support frame 35 horizontally to the predetermined position. Then, the operator rotates the second screw 36, causing the base 37 to slowly descend until it is in close contact with the ground, forming a stable support. At the same time, the counterweight 31 plays a role in balancing the center of gravity, enhancing the overall stability of the vehicle and laying a solid foundation for subsequent operations. After the support preparation is completed, the bearing ring is placed in the placement box 45. Then, the electric push rod 41 installed on one side of the bottom of the support plate 29 is powered on and started. The electric push rod 41 extends and retracts, pushing the second rotating block 44 connected to it. Since the second rotating block 44 is rotatably connected to the output end of the electric push rod 41, and the first rotating block 43 is rotatably connected to the support block 42, the operation is complete. The first rotating block 43 is connected to the second rotating block 44. The movement of the second rotating block 44 drives the first rotating block 43 to rotate around the support block 42, so that the first rotating block 43 can position bearing rings of different specifications and ensure that they are stably placed on the support plate 29. Finally, the first transmission motor 22 starts and drives the worm gear 23 to rotate. The worm gear 23 meshes with the worm wheel 24 to transmit power to the first screw 25 to make it rotate. The moving block 26, which is threaded to the first screw 25, moves axially when the screw rotates. The slider 27 on the moving block 26 slides along the guide groove of the limiting block 28 of the support seat 21, restricting the moving block 26 to only move vertically and avoiding deviation and swaying. The moving block 26 drives the support plate 29 to rise or fall smoothly, thereby completing the lifting operation of the accurately positioned bearing rings and meeting different operation requirements.

[0038] 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.
