[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0053] Example 1

[0054] Please see Figure 1-7 This invention provides a technical solution for a slewing bearing overturning machine, comprising a front frame 100, a overturning frame 300, and a rear frame 200. (See reference...) Figure 1 The front frame 100 and rear frame 200 are located on both sides of the tilting frame 300, used to support and transport the slewing bearing 400; the tilting frame is used to tilt the slewing bearing, while the front and rear frames can be understood as transport equipment. Adjustable feet 11 are also installed at the bottom of the front and rear frames.

[0055] The tilting frame 300 includes:

[0056] Base frame 1;

[0057] Rotating frame 2 is rotatably installed inside base frame 1; vertically distributed flow strips 4 are installed inside rotating frame 2, and pulleys 41 are installed on the vertically distributed flow strips 4 facing each other; the flow strip on the lower side is at the same height as the flow strips on the front frame and the rear frame in the initial position, which facilitates the smooth sliding of the slewing bearing before and after flipping.

[0058] Electrical control cabinet 3 is installed on one side of base frame 1; the electrical control cabinet is used to control the movement of the drive components, causing the rotating frame to rotate 180°.

[0059] A driving component is installed between the rotating frame 2 and the base frame 1, and is used to drive the rotating frame 2 to rotate 180°.

[0060] A limiting member is installed inside the rotating frame 2 to limit the movement of the slewing bearing 400; when the rotating frame 2 rotates, the limiting member abuts against the slewing bearing 400.

[0061] like Figure 2 As shown, adjustable feet 11 are installed at the bottom of the base frame 1, and adjusting bolts 12 are installed on the adjustable feet 11. The adjusting bolts 12 are threadedly connected to the base frame 1. Reinforcing ribs 13 are also fixedly installed on the base frame 1. The base frame 1 can be constructed entirely of channel steel, with reinforcing ribs 13 on the sides to increase strength. The bottom has 6 adjustable feet 11 to support the tilting machine. The design of the adjustable feet 11 facilitates subsequent adjustment of the tilting machine's height to adapt to the working environment.

[0062] like Figure 2 As shown, the rotating frame 2 is square-shaped with fork-shaped plates 21 on both sides to increase the overall structural strength; the flow strips 4 inside the rotating frame 2 are divided into two groups and symmetrically distributed vertically; (reference) Figure 2 A total of eight flow bars are arranged on the top and bottom to transport, support and protect the slewing bearing.

[0063] like Figure 3 and 4 As shown, this is a single flow bar structure. The flow bar 4 also includes a fixed plate 42, side plates 43, and a strip-shaped tube 44. The fixed plate 42 is fixedly connected to the rotating frame 2. The strip-shaped tube 44 is fixed on the side of the fixed plate opposite to the side plates, and its length is less than the length of the fixed plate. Two sets of opposing side plates 43 are installed on each set of fixed plates 42. The side plates 43 are bent plates. A roller is installed between the two sets of side plates 43, and a pulley 41 is installed on the roller. The height of the pulley should extend to the side plates to facilitate sliding and driving the slewing bearing to move.

[0064] like Figure 5 As shown, the driving component includes a position plate 22 and a rotary drive component. The position plate 22 is fixedly connected to the base frame 1. The body of the rotary drive component is connected to the position plate 22, and the output end of the rotary drive component is connected to the rotating frame 2.

[0065] A position plate 23 is installed on the inner wall of the base frame 1 on the side away from the rotary drive component. A lateral rotating component 9 is installed on the side of the position plate 23 facing the rotating frame 2. Figure 7 As shown. The lateral rotating component includes a lateral slewing bearing, the inner ring of which is connected to the rotating frame 2, and the outer ring of which is fixedly connected to the position plate. The electrical control system uses electrical control components in the control box to control the motor. The lateral slewing bearing and worm gear reducer 5 installed on the other side of the rotating frame ensure the rotation effect on both sides of the rotating frame. The motor drives the rotation, thereby causing the rotating frame to rotate 180°. The 180° limit can be determined by controlling the rotation time or implemented using a mechanical structure.

[0066] The rotary drive components are a worm gear reducer 5 and a motor 6. The output end of the worm gear reducer 5 is connected to the rotating frame 2, and the motor 6 is connected to the worm gear reducer 5. The housing of the worm gear reducer is connected via... Figure 2 Multiple bolts are used to fix the position plate one.

[0067] The limiting component includes a guide post connecting plate 7 and an adjusting guide rod 8. The guide post connecting plate 7 has multiple sets of curved slots 71. In this embodiment, the adjusting guide rod can be a lead screw. The bottom is electrically driven to move the guide sleeve on the lead screw up and down, and to achieve active contact with the slewing bearing.

[0068] Example 2

[0069] like Figure 8-12 As shown, another embodiment of this utility model is provided. Based on embodiment 1, the guide post connecting plate 7 is provided in two sets, and each set of guide post connecting plates 7 is provided with two plates located at the two ends of the corresponding adjusting guide rod 8; the adjusting guide rod 8 is provided in two sets; the slots 71 of the two sets of guide post connecting plates 7 are arranged facing each other.

[0070] The two sides of the guide post connecting plate 7 are respectively fixed to the fixing plate 42 on the corresponding flow strip 4.

[0071] The adjusting guide rod 8 includes a guide post 81, with an end cap 82 mounted on the top and a detachable gasket 83 mounted on the bottom. The outer diameters of both the gasket 83 and the end cap 82 are larger than the outer diameter of the guide post 81. A gasket sleeve 84 and a linear bearing 85 are mounted on the guide post 81. Gasket sleeves 84 are mounted on both sides of the linear bearing 85, and a rubber sleeve 86 is mounted on the outside. The rubber sleeve 86 outside the linear bearing 85 is used to move and abut against the slewing bearing 400.

[0072] The main function of the adjusting guide rod is to support the slewing bearing during the rotation process. The guide sleeve uses a linear bearing, allowing for smoother sliding on the guide post. The linear bearing is further protected by a rubber sleeve to better safeguard the surface quality of the slewing bearing. Especially when the slewing bearing rotates 90°, the downward pressure can often cause surface damage, affecting its service life. The spacing between the two sets of adjusting guide rods can be adjusted by connecting them to slots at different positions on the guide post connecting plate.

[0073] like Figure 11 As shown, both the front frame 100 and the rear frame 200 are equipped with multiple sets of unidirectional flow strips 4.

[0074] Work methods:

[0075] First, the adjustable feet of the tilting machine need to be adjusted so that the height of the flow bar at the bottom of the tilting frame is the same as the height of the front and rear frames. Figure 1 As shown;

[0076] Next, select the appropriate slot in the guide column connecting plate according to the size of the slewing bearing product, install the adjusting guide rod in the slot, and all the preparations before flipping are completed.

[0077] The flipping process is as follows: Figure 12 As shown, the slewing bearing is hoisted onto the front frame using a crane; it can then be manually pushed into the rotating frame of the tilting frame, so that the slewing bearing rests against the two rubber bushings; pressing the start button on the control box causes the rotating frame to begin tilting under the drive of the motor, and the slewing bearing rotates 180° with the rotating frame; after tilting, the slewing bearing can be manually pushed onto the rear frame; the tilting of this slewing bearing is now complete. Compared to manual operation, this invention simplifies the slewing bearing tilting process and improves the manufacturing efficiency of slewing bearings.

[0078] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
