[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 9 The present invention preferably provides a rotary bearing press-fitting machine for caster brackets, comprising a frame 1, a rotary disk 2 disposed on the frame 1, a plurality of mounting holes 21 evenly distributed around the rotary disk 2, a drive motor 22 disposed at the bottom of the rotary disk 2, and press-fitting fixtures 3 for mounting caster brackets disposed on the mounting holes 21. The machine frame 1 is arranged around the rotary disk 2 in sequence as follows: a bearing sleeve loading structure 4 for placing bearing sleeves on the caster bracket, and a bearing loading structure 4 for placing bearings on the bearing sleeves. 5. Press-fitting structure for pressing bearings, bearing sleeves, and caster brackets; 6. Unloading structure for removing the press-fitted bearing sleeves and caster brackets from the press-fitting fixture 3; 7. Feeding device 41 is provided on one side of the bearing sleeve loading structure 4; feeding device 51 is provided on one side of the bearing loading structure 5; unloading groove 71 is provided on one side of the unloading structure 7; press-fitting positioning device 8 is provided on the press-fitting structure 6 to ensure the accuracy of the press-fitting position; and an electrical control console 11 for controlling the opening and closing of various electrical control devices is also provided on the frame 1.

[0027] During operation, the pressing fixture is installed and fixed into the mounting hole. At one workstation, a worker manually installs the caster bracket onto the pressing fixture, the bearing sleeve onto the bearing sleeve feeding structure, and the bearing onto the bearing feeding structure. After the machine is started via the control panel, the bearing sleeve feeding structure starts first, taking the bearing sleeve from the first feeding device and placing it on the caster bracket. Then, the rotating disc moves the pressing fixture containing the bearing sleeve and caster bracket to the position of the bearing feeding structure. After the bearing feeding structure starts, the bearing is taken from the second feeding device and placed on the bearing sleeve. Then, the rotating disc moves the pressing fixture containing the bearing sleeve, bearing, and caster bracket to the position of the pressing structure. The pressing positioning device starts to position and fix the rotating disc. At this time, the pressing structure starts pressing, pressing the bearing into the bearing sleeve, and the bearing sleeve into the caster bracket. This process is simultaneous. After pressing is completed, the rotating disc rotates, moving the pressed workpiece to the unloading structure, and the workpiece is sent to the unloading chute for unloading, completing the entire process. Since the rotating disk is equipped with several pressing fixtures, each device completes its work once every time the rotating disk rotates, thus enabling the continuous output of workpieces. This process can be controlled by the control console to control the opening and closing time of each electrical control device.

[0028] The mounting hole 21 in this invention includes a large hole 211 and several small holes 212 evenly distributed around it. The pressing fixture 3 includes a movable column 31 mounted on the large hole 211. An upper plate 32 and a lower plate 33 are respectively provided on the upper and lower sides of the rotating disk 2 and are movably sleeved on the movable column 31. The lower plate 33 is fixedly connected to the rotating disk 2. Several side rods 34 are fixed at the bottom of the upper plate 32 and inserted to the lower side of the lower plate 33. A spring 35 is provided between the bottom wall of the upper plate 32 and the top wall of the rotating disk 2 and outside the side rods 34. A pressing sleeve 36 for placing a caster bracket is movably sleeved on the top of the movable column 31. A spring 37 is provided between the pressing sleeve 36 and the upper plate 32 and outside the movable column 31. The inside of the pressing sleeve has space for the bearing sleeve and bearing to move during the pressing process. Both large and small holes are used for installing press-fitting fixtures. The large holes are used for installing movable columns, and the small holes are used for installing side rods. Since there are several springs, and the elastic force of multiple springs is smaller than that of springs, when the press-fitting structure starts, it first contacts the bearing on the press-fitting sleeve and presses it into the bearing sleeve. Spring 1 retracts first, and the upper plate presses down to its limit. Then, the continuous operation of the press-fitting structure presses the bearing sleeve into the caster bracket. Spring 2 retracts, and the bearing sleeve is gradually pressed into place, completing the press-fitting work. The purpose of setting springs 1 and 2 is to make the press-fitting process of bearing sleeve and bearing flexible, avoiding deformation of the workpiece caused by strong impact force.

[0029] The bearing sleeve feeding structure 4 described in this utility model includes a vertical frame 42 mounted on a frame 1. A transverse translation frame 43 is mounted on one side of the top of the vertical frame 42. A transverse moving component 44 is mounted at the upper limit of the transverse translation frame 43.

The vertical moving component 47 can also move up and down on the transverse moving component 47 via the electric push rod, thereby realizing dual-axis movement. This allows the gripper at the bottom to clamp a pair of bearing sleeves and place them on the caster bracket of the pressing fixture. This process can be programmed by an electronic control console. The gripper is activated by a cylinder to grip or open, which can be achieved using existing pneumatic grippers.

[0030] The feeding device 41 described in this utility model includes a side frame 411 mounted on the frame 1, and a feeding trough 412 is provided on the top of the side frame 411. The cross-sectional shape of the feeding trough should match the shape of the bearing sleeve.

A second cylinder 56 is mounted at the bottom of the second vertical moving component 55. A second gripper 57, which can clamp the bearing, is mounted at the bottom of the second cylinder 56. The second transverse translation frame provides the second transverse moving component for movement. The electric push rod can drive the second transverse moving component to move left and right. The second vertical moving component can also move up and down on the second transverse moving component via the electric push rod, thereby realizing dual-axis movement. This allows the second gripper at the bottom to clamp the bearing and place it on the bearing sleeve. This process can be programmed by an electronic control console. The second gripper is activated by the second cylinder to clamp or open, and can be implemented using existing pneumatic clamps.

The vertical moving component 63 62 can also move up and down on the transverse moving component 63 62 via the electric push rod, thereby realizing dual-axis movement. This allows the gripper 67 63 at the bottom to clamp the entire workpiece and place it on the unloading groove. This process can be implemented by programming on an electronic control console. The gripper 63 62 is activated by the cylinder 63 62 to clamp or open, and can be implemented using existing pneumatic clamps.
