Description

Technical Field

[0001] This utility model relates to the technical field of flipping devices, and in particular to a flipping device for a turntable bearing. Background Technology

[0002] Slewing bearings are special-structured bearings capable of simultaneously withstanding large axial loads, radial loads, and overturning moments. They generally meet the diverse needs of various host machines operating under different conditions. During machining, slewing bearings need to be rotated after clamping and positioning to facilitate inspection or machining operations.

[0003] Existing flipping devices typically use a drive mechanism to move two clamping plates close to the outer side of the turntable bearing for clamping, and then use the drive mechanism to control the bearing's rotation. However, the clamping method of existing devices obstructs the outer wall of the bearing, which is not conducive to the inspection and processing of the bearing. Therefore, a flipping device that does not obstruct the outer wall was designed to address the above-mentioned problem. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0044] Currently, existing flipping devices typically use a drive mechanism to move two clamping plates close to the outer side of the turntable bearing for clamping, and then use the drive mechanism to control the bearing's rotation. However, the clamping method of existing devices obstructs the outer wall of the bearing, which is not conducive to the inspection and processing of the bearing.

[0045] like Figure 1-4 As shown, this embodiment of the invention provides a turning device for a turntable bearing.

[0046] The device includes: a worktable 11 with a drive mechanism 12 on top; a clamping assembly 2 on the worktable 11, the clamping assembly 2 further including: a cylinder 21, one end of which passes through the worktable 11 and is rotatably connected to the worktable 11, and a toothed ring on its outer wall meshes with a gear on the drive mechanism 12, the drive mechanism 12 driving the cylinder 21 to rotate; a protruding plate 22, fixedly disposed at one end of the cylinder 21; a threaded rod 23, one end of which is inserted into the interior of the cylinder 21 and is rotatably connected to the cylinder 21; a movable plate 24, disposed inside the cylinder 21 and penetrated by the threaded rod 23, and threadedly connected to the threaded rod 23; a crossbar 25, one end of which is inserted into the interior of the cylinder 21 and fixedly connected to the movable plate 24; and a protruding rod 26 disposed at one end of the protruding plate 22 and the crossbar 25.

[0047] Specifically, the drive mechanism 12 consists of a motor, gears, and a gear ring. The gear ring is fixedly sleeved on the outside of the cylinder 21 and meshes with the gear at one end of the motor. Therefore, when the motor drives the gear to rotate, it will mesh with the gear ring, thereby driving the cylinder 21 to rotate together.

[0048] In use, simply place the flip bearing onto one end of the convex plate 22, ensuring its outer wall aligns with the convex rod 26 (smaller bearings can be held directly, while larger bearings require a support bracket to move them to the appropriate position). Then, control the rotation of the threaded rod 23. During rotation, it will thread into the moving plate 24. Because the moving plate 24 is fixedly connected to the crossbar 25, restricting its rotation, the rotation of the threaded rod 23 will drive the moving plate 24 to move inside the cylinder 21, pulling the crossbar 25 into the cylinder 21 and causing the convex rod 26 at one end of the crossbar 25 to align with the inner wall of the bearing, thus clamping and securing the bearing. Finally, the drive mechanism 12 rotates the cylinder 21, causing the turntable bearing to flip accordingly. It facilitates the inspection and processing of the bearing (when clamping the bearing, two protrusions 26 are located on the outside of the bearing and one protrusion 26 is located on the inside of the bearing, which can stabilize the back and forth sway of the bearing. By controlling the protrusions 26 to move closer, the inner and outer walls of the bearing can be clamped. The clamping force depends on the tension of the crossbar 25. Adjusting the crossbar 25 can clamp the bearing stably).

[0049] Furthermore, the protruding rod 26 is rotatably connected to the protruding plate 22 and the crossbar 25.

[0050] The rotating connection allows the bearing to be rotated, making it easy to inspect all the outer walls of the bearing.

[0051] Furthermore, the clamping assembly 2 also includes a knob 27, which is disposed at one end of the threaded rod 23.

[0052] The knob 27 is designed for easy gripping and controls the rotation of the threaded rod 23. At the same time, the grooves on the surface of the knob 27 can increase friction when rotating.

[0053] Furthermore, the clamping assembly 2 also includes a rubber sleeve 28, which is fixedly sleeved on the outer side wall of the protruding rod 26.

[0054] The design of the rubber sleeve 28 can protect the bearing when clamped, and at the same time increase the friction to make it more secure.

[0055] Furthermore, the workbench 11 is provided with a lifting assembly 3, which further includes: a vertical plate 31, fixedly mounted on the top of the workbench 11, and having multiple adjustment holes on its surface; a slider 32, slidably mounted on the inner side of the vertical plate 31; a support plate 33, fixedly mounted on one side of the slider 32; a rod 34, one end of which is inserted into the interior of the slider 32; a pull plate 35, mounted on one end of the rod 34; and an insert rod 36, fixedly mounted on one side of the pull plate 35.

[0056] When placing the bearing, it can be placed directly on the top of the support plate 33. Then, pull the pull plate 35 to disengage the insertion rod 36 on one side of the pull plate 35 from the positioning hole on the upright plate 31, releasing the fixation of the slider 32. Push the slider 32 to move inside the upright plate 31 and move it to a suitable position according to the width of the bearing (the suitable position means that the height of the bearing and the protrusion 26 are on the same horizontal line). Push the rod 34 to insert into the inside of the slider 32 and at the same time drive the insertion rod 36 to insert into the positioning hole on the upright plate 31 to limit the height of the slider 32. At this time, operate the clamping assembly 2 to clamp the bearing.

[0057] Furthermore, the lifting assembly 3 also includes: a baffle 37 disposed at one end of the rod 34; and a spring 38 sleeved on the outside of the rod 34.

[0058] The design of the baffle 37 and the spring 38 allows the spring 38 to push the baffle 37 to move, so that the rod 34 can be stably inserted into the slider 32, thus stabilizing the position of the rod 34.

[0059] Furthermore, the lifting assembly 3 also includes a cone 361 disposed at one end of the insertion rod 36.

[0060] The pointed end of the cone 361 makes it easier to insert into the positioning hole.

[0061] Furthermore, the lifting assembly 3 also includes a handle 39, which is disposed on one side of the pull plate 35.

[0062] The handle 39 is designed for easy gripping. It facilitates dragging the slider 32 to slide inside the upright plate 31.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
