Description

Technical Field

[0001] The utility model relates to the technical field of bearing steel ball installation, in particular to an adjustable bearing sleeve fitting instrument with a pushing device. Background Art

[0002] A bearing is a mechanical component primarily used to reduce friction during movement. It consists of two inner and outer rings and multiple rolling elements (such as balls or rollers). When the inner ring rotates, the rolling elements roll on the outer ring, resulting in smoother rotation and reduced wear.

[0003] Prior art publication number CN206972781U describes a new tapered roller bearing assembly instrument. By configuring the third motor as a separate electrical control switch, it has both manual and electric modes. In electric mode, the third motor is configured to rotate the disc one full revolution once all rollers are positioned within the retainer, securing the rollers in their proper positions within the retainer.

[0004] When installing the rolling elements (steel balls) on existing bearings, a bearing assembly instrument is required. However, most existing bearing assembly instruments do not have a pushing device, which makes it inconvenient to unload the steel balls in an orderly manner and to adjust the angle of the bearing. The steel balls are not convenient to be installed in different positions in the bearing, and the work efficiency is low. Therefore, we propose an adjustable bearing assembly instrument with a pushing device. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1:

[0021] See also Figure 1-3 The utility model provides a technical solution: an adjustable bearing assembly instrument with a pushing device, comprising a workbench 1, a rotating component provided on the workbench 1, the rotating component comprising a driven gear 5, and the middle portion of the lower surface of the driven gear 5 is rotatably connected to the workbench 1 through a bearing, and four groups of arc-shaped limit plates 6 are installed on the upper surface of the driven gear 5, and a bearing body 7 is provided between the four groups of arc-shaped limit plates 6; before use, the electrical ends of each electrical device are electrically connected to the external power supply and the electrical end of the controller, the bearing body 7 is placed on the top of the driven gear 5, and the four groups of arc-shaped limit plates 6 limit the position of the bearing body 7, and the rotating component can drive the driven gear 5 to rotate, thereby adjusting the angle of the bearing body 7;

[0022] The rear end of the upper surface of the workbench 1 is connected to a steel ball feeding box 8 through a bracket. A feeding port 13 is provided on the bottom wall of the steel ball feeding box 8, and hinge seats 10 are installed on the bottom ends of the inner walls on both sides of the steel ball feeding box 8. A movable baffle 11 is rotatably connected in the two sets of hinge seats 10, and compression springs 12 are provided between the two sets of movable baffles 11 and the inner walls on both sides of the steel ball feeding box 8. A pushing device 9 is provided on the steel ball feeding box 8, and the pushing device 9 includes a lower pressure plate 906, and the lower pressure plate 906 is vertically slidably connected to the inner wall of the steel ball feeding box 8; the steel balls are placed inside the steel ball feeding box 8, and the lower pressure plate 906 can be driven to press down through the action of the pushing device 9. The pressure plate 906 presses down the steel balls, causing the two sets of movable baffles 11 to rotate in opposite directions. At this time, the two sets of compression springs 12 are compressed, and the steel balls can pass through the gap between the two sets of movable baffles 11, causing the steel balls to fall from the discharge port 13 into the bearing body 7. When the lower pressure plate 906 does not continue to move downward, the two sets of compressed compression springs 12 automatically return to their positions, causing the two sets of movable baffles 11 to rotate closer to each other. At this time, the steel balls no longer fall, and with the action of the rotating component, the bearing body 7 rotates a certain angle each time, realizing the automatic discharge of steel balls, so that the steel balls can be installed in the bearing in an orderly manner, without the need for manual installation of steel balls, effectively improving work efficiency.

[0023] Among them, preferably, the pushing device 9 also includes a fixed frame 900, the fixed frame 900 is located on the left outer wall of the steel ball discharge box 8, and a stepping motor 901 is installed on the top of the fixed frame 900; the fixed frame 900 is fixedly installed on the left outer wall of the steel ball discharge box 8.

[0024] Preferably, the output end of the stepper motor 901 is connected to a screw rod 902, and a threaded block 903 is threadedly connected to the screw rod 902. A connecting slider 905 is installed on the side of the threaded block 903 close to the steel ball unloading box 8. A through groove 904 is opened on the left side wall of the steel ball unloading box 8, and the through groove 904 is slidably connected to the connecting slider 905. The connecting slider 905 is connected to the side wall of the lower pressure plate 906; the threaded block 903 is fixedly connected to the connecting slider 905, and the connecting slider 905 is fixedly connected to the lower pressure plate 906. The operation of the stepper motor 901 can drive the screw rod 902 to rotate. The threaded block 903 threadedly connected to the screw rod 902 is limited by the sliding of the through groove 904 and the connecting slider 905, so that the lower pressure plate 906 moves down or up. When the lower pressure plate 906 moves to the top position, the steel balls can be smoothly added to the steel ball discharge box 8. Each time the lower pressure plate 906 presses down, the steel balls are squeezed, so that the steel balls fall from the discharge port 13 in an orderly manner.

[0025] Preferably, the rotating component also includes an L-shaped plate 2, which is fixedly mounted on the right end of the upper surface of the workbench 1, and a servo motor 3 is connected to the top of the L-shaped plate 2, the output end of the servo motor 3 is connected to a rotating shaft, and a driving gear 4 is installed at the bottom of the rotating shaft, and the driving gear 4 is meshed with the driven gear 5; the operation of the servo motor 3 can drive the driving gear 4 at the bottom of the rotating shaft to rotate, because the driving gear 4 is meshed with the driven gear 5 and the driven gear 5 is rotationally connected to the upper surface of the workbench 1 through the bearing, so that the bearing body 7 on the driven gear 5 rotates a certain angle each time.
