The sleeve rod passes through the support and the lifting plate in sequence, and the sleeve rod is located below the bead pressing mechanism.

[0018] An assembly method using the automatic ball-installing device of the bearing bracket comprises the following steps:

[0019] The first step: place the bearing bracket on the support plate in the bracket hopper, and the bearing bracket gathers to the intersection with the layer plate along the tilt direction of the support plate; the push cylinder works to push the movable layer plate to slide upward relative to the fixed layer plate, so that the movable layer plate moves from the lower fixed layer plate to be flush with the top surface of the higher fixed layer plate, and the bearing bracket is moved from the height of the lower fixed layer plate top surface to the height of the higher fixed layer plate top surface, thereby moving the bearing bracket upward layer by layer until it reaches the conveyor belt;

[0020] Step 2: The conveyor belt is driven by the conveyor motor, and the bearing bracket continues to move toward the direction of the push frame mechanism after being guided by the guide bar; the output end of the push frame cylinder retracts so that the frame hole on the push frame block is exactly located at the end of the conveyor belt, and the bearing bracket moves with the conveyor belt until it enters the frame hole;

[0021] Step 3: The push-rack cylinder works to push the push-rack block with the bearing bracket toward the bracket feeding mechanism until the rack hole moves between the two arms of the moving rack plate;

[0022] Step 4: The frame moving cylinder works, and applies force to the end of the bearing bracket through the frame moving plate, so that the bearing bracket moves axially together with the frame moving plate, so that the bearing bracket is sleeved onto the sleeve rod of the rotating mechanism;

[0023] Step 5: synchronously, the balls are placed on the support plate in the ball hopper, and the balls gather at the intersection with the layer plate along the tilt direction of the support plate; the push cylinder works to push the movable layer plate to slide upward relative to the fixed layer plate, so that the movable layer plate moves from the lower fixed layer plate to be flush with the top surface of the higher fixed layer plate, and the balls are transferred from the height of the lower fixed layer plate top surface to the height of the higher fixed layer plate top surface, thereby transferring the balls upward layer by layer until they are in the U-shaped seat of the ball feeding mechanism;

[0024] Step 6: The brush cylinder works, and the brush plate moves along the inner bottom surface of the U-shaped seat, causing the balls to fall into the groove, and the excess balls are brushed into the residual material holes at both ends and fall through the residual material pipe; the feeding cylinder works, pulling the baffle plate, so that the small through hole on the baffle plate connects the small hole on the back plate with the notch of the small groove, and the balls in the small groove fall into the ball drop seat of the ball pressing mechanism through the small through hole, the small hole and the external air pipe;

[0025] Step 7: The ball-pushing cylinder works, and the ball dropped from the ball-dropping seat is pushed to the bottom of the ejector through the ball-pushing plate; the ball-pressing cylinder works, and the force is applied to the ball through the ejector, so that the ball passes through the support seat downward and is pressed onto the bearing bracket on the sleeve rod;

[0026] Step 8: The lifting cylinder works, driving the ball pressing mechanism to move upward through the lifting plate; the motor rotates, driving the bearing bracket mounted thereon to rotate through the sleeve rod; the lifting cylinder works in the reverse direction, causing the ball pressing mechanism to move downward and close to the bearing bracket; repeat step 7 to complete the pressing of the ball after the bearing bracket rotates an angle;

[0027] Step 9: Repeat step 8 until all the balls on the bearing bracket are press-fitted; remove the bearing bracket from the sleeve rod to complete the installation of the balls on the single-piece bearing bracket.

[0028] The beneficial effects of the present invention are as follows:

[0029] The invention has a compact and reasonable structure and is easy to operate. The bearing bracket and the balls are separately and centrally loaded. The bearing bracket is installed on the end of the rotating mechanism after passing through the bracket hopper, the conveyor belt, the push-rack mechanism and the bracket loading mechanism. The balls are orderly transported to the ball pressing mechanism after passing through the ball hopper, the ball loading mechanism and the external air pipe. The balls are pressed into the wall holes of the bearing bracket under the action of the ball pressing mechanism. After the bearing bracket rotates at a set angle with the rotating mechanism, the balls are installed in the remaining generatrix direction, thereby completing the orderly installation of all the balls on the bearing bracket. The degree of automation is high, the ball installation speed is greatly improved, the work efficiency is improved, the ball installation quality and consistency are good, and the work intensity of personnel is low.

[0030] The present invention also includes the following advantages:

[0031] The loading of the bearing bracket in the bracket hopper and the loading of the balls in the ball hopper are based on the same principle. Both work by pushing the push cylinder to push the moving layer plate relative to the fixed layer plates that fit in front and behind, so that the moving layer plate transfers the materials on the fixed layer plate at a lower height to the fixed layer plate at a higher height, layer by layer upward, so as to orderly lift the bearing bracket onto the conveyor belt, or lift the balls into the ball loading mechanism; the top surfaces of the moving layer plate and the fixed layer plate are tilted downward to facilitate the transfer of materials on the top surfaces of adjacent layer plates, which helps to effectively increase the material height;

[0032] The guide bars are symmetrically arranged at the ends of the conveyor belt, and corresponding grooves are opened in the middle. The existence of the guide bars facilitates the bearing bracket driven by the conveyor belt to adjust its angle along its own circumferential direction, so that the circumferential angle of the bearing bracket is consistent when entering the push frame mechanism, which is convenient for subsequent bead pressing;

[0033] The lifting mechanism is used to lift the bead pressing mechanism, so that when the rotating mechanism drives the bearing bracket to rotate, the bead pressing mechanism and the bearing bracket are separated to prevent interference between the rotating mechanism and the bead pressing mechanism when the rotating mechanism is working;

[0034] The balls in the ball hopper are lifted upward to the U-shaped seat of the ball feeding mechanism by the action of the pushing cylinder. The brush cylinder works and applies force to the balls in the U-shaped seat through the brush plate, so that the balls fall into the grooves and are arranged in sequence in the small grooves, or the balls fall back into the ball hopper through the residual material holes at both ends; the feeding cylinder works, driving the baffle to move against the back plate, and when the small through holes on the baffle connect the small holes on the back plate with the notches of each small groove, the balls fall into the ball pressing mechanism through the small through holes on the baffle, the small holes on the back plate, and the external air pipe; the presence of the brush cylinder and the brush plate makes the balls arranged in order in the grooves, and the presence of the feeding cylinder and the baffle determines whether the balls are fed into the air pipe.
