Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] Example 1:

[0029] like Figures 1-6As shown, a multi-station rotary bearing installation device includes a turntable 1 for supporting the rotary wheel. The turntable 1 has at least two mounting positions for engaging the rotary wheel. In this example, the turntable 1 has four mounting positions: the first mounting position is for placing the bottom bearing, the second mounting position is for manually or automatically placing the rotary wheel 6, the third mounting position is for placing the top bearing, and the fourth mounting position is for pressing the rotary wheel 6 and the bearing together and removing the rotary wheel 6. The four mounting positions are distributed sequentially along the edge of the turntable 1. The installation device also includes a first gripping structure 2 for gripping the assembled rotary wheel 6, a second gripping structure 3 for gripping the bearing placed below the rotary wheel 6, a third gripping structure 4 for gripping the bearing placed above the rotary wheel 6, and a pressing structure 5 for pressing the bearing. The first gripping structure 2, the second gripping structure 3, the third gripping structure 4, and the pressing structure 5 are respectively located on the side of the turntable 1. It should be noted that in this example, the first gripping structure 2 and the pressing structure 5 are arranged in cooperation, and both are located in the same position on the turntable 1.

[0030] The mounting components on the turntable 1 include a base 11, a movable sleeve 12, a sleeve 13, and an inner rod 14. The base 11 is fixedly positioned on the turntable 1 at a predetermined location. The sleeve 13 is fixedly positioned above the base 11, and the sleeve 13 is hollow inside, with an open end away from the base 11. The inner rod 14 is slidably mounted inside the sleeve 13, and the movable sleeve 12 is slidably mounted outside the sleeve 13. The outer side of the inner rod 14 is used to fit the inner ring of the bearing. The sleeve 13 is used to cooperate with the rotating wheel 6. A concave hole with a larger diameter is provided on the upper end face of the sleeve 13, corresponding to the protruding structure 61 at the center of the rotating wheel 6, so that the rotating wheel 6 can be embedded in the sleeve 13, maintaining a relatively stable position for easy pressing and splicing between the bearing and the rotating wheel 6. A first spring 16 is provided between the movable sleeve 12 and the base 11 to help the movable sleeve 12 return to its original position. A second spring 17 is provided between the inner rod 14 and the bottom of the sleeve 13 to help the inner rod 14 return to its original position. When the clamping structure 5 is pressed down, it first contacts the inner rod 14. The inner rod 14 is under pressure and moves downward against the second spring 17. Then, the clamping structure 5 contacts the bearing located above the rotating wheel 6. When the bearing is pressed downward, it drives the rotating wheel 6 and the movable sleeve 12 to move downward against the pressure of the first spring 16 until both bearings are pressed into the rotating wheel 6, completing the assembly of the rotating wheel 6 and the bearings. To prevent the inner rod 14 from detaching from the sleeve 13, a larger diameter disc-shaped snap-fit ​​connector 15 is provided at one end of the inner rod 14 inside the sleeve 13, forming a snap-fit ​​engagement with the end of the sleeve 13. The bottom of the sleeve 13 is provided with an opening, and the bottom of the sleeve 13 is detachably connected to the base 11 by screws, which facilitates the installation of the inner rod 14 and the second spring 17 inside the sleeve 13. The outer diameter of the sleeve 13 corresponds to the outer ring size of the bearing on the rotating wheel 6, so that the sleeve 13 can abut against the bearing, thereby cooperating with the clamping structure 5 to achieve the purpose of pressing the two bearings into the rotating wheel 6.

[0031] The clamping structure 5 includes a pressing rod 51 and a pressing cylinder 52. One end of the pressing rod 51 is fixedly connected to the pressing cylinder 52, and the other end of the pressing rod 51 is provided with a concave hole corresponding to the inner rod 14 or the bearing, which facilitates the alignment of the pressing rod 51 with the inner rod 14 or the bearing, so that the pressing rod 51 can accurately press the bearing and avoid pressing the rotating wheel 6. The outer diameter of the pressing rod 51 is smaller than the diameter of the hole in the center of the rotating wheel 6 used to install the bearing, so that the pressing rod 51 can be inserted into the center hole of the rotating wheel 6 and press the bearing inside. In this example, the bottom edge of the pressing rod corresponds to the outer ring of the bearing, so that when pressing down, pressure is applied to the outer ring of the bearing, avoiding deformation of the bearing due to pressure and affecting its performance.

[0032] The first gripping structure 2 includes a finger cylinder 21 for gripping the rotating wheel 6, a vertical motion structure for controlling vertical movement, and a horizontal motion structure 22 for controlling horizontal movement. In this example, the vertical motion structure is the pressing cylinder 52 in the clamping structure 5. After the clamping engagement between the rotating wheel 6 and the bearing is completed, the finger cylinder 21 in the first gripping structure 2 can clamp the edge of the rotating wheel 6, thereby removing the rotating wheel 6 from the mounting position. The horizontal motion structure 22 includes a horizontal slide rail 221, a horizontal slider 222, a transmission belt 223, and a motor 224. The transmission belt 223 is connected to the motor 224 and is also fixedly connected to the horizontal slider 222. The horizontal slider 222 is slidably mounted on the horizontal slide rail 221.

[0033] The turntable 1 has a tray in the middle for placing the assembled wheel 6. The first gripping structure 2 grips the wheel 6 and places it on the tray, and then it is removed manually. In this example, the second mounting part on the turntable 1 is provided with a manual operation area, which facilitates the placement and removal of the wheel 6 by manual operation.

[0034] The second gripping structure 3 and the third gripping structure 4 have the same structure. Taking the second gripping structure 3 as an example, the second gripping structure 3 includes a horizontal gripping member 31 with horizontal displacement, a vertical gripping member 32 with vertical displacement, and a gripper cylinder 33. The gripper cylinder 33 is disposed on the vertical gripping member 32, and the vertical gripping member 32 is disposed on the horizontal gripping member 31. In this example, both the horizontal gripping member 31 and the vertical gripping member 32 use cylinders as power sources.

[0035] It also includes a control structure, which is communicatively connected to the turntable 1, the first gripping structure 2, the second gripping structure 3, the third gripping structure 4 and the clamping structure 5, respectively, to control their sequential actions. It should be noted that the control structure adopts existing control methods, including but not limited to controlling the sequential action order of the cylinders and the action of the motor 224.

[0036] During implementation, the second gripping structure 3 and the third gripping structure 4 grip the bearings on both sides of the rotating wheel 6 respectively. With the cooperation of the clamping structure 5, the bearings are automatically pressed into the rotating wheel 6, improving the installation efficiency of the bearings on the rotating wheel 6 and reducing labor costs. By setting the structure of the installation part on the turntable 1, a multi-segment pressing structure is formed. With the cooperation of the clamping structure 5, the bearings are accurately pressed into the central hole area of ​​the rotating wheel 6. By setting the first gripping structure 2, after the assembly of the rotating wheel 6 and the bearing is completed, the rotating wheel 6 is removed from the installation part, realizing cyclic operation and improving overall efficiency.
