Description

Technical Field

[0001] This invention relates to an automatic assembly device, and more specifically, to a bracket mold bearing and mounting ring assembly apparatus and method. Background Technology

[0002] Currently, the assembly of bearings and mounting rings is required during the bracket mold assembly process. The traditional assembly method involves first placing the bracket mold flat on a workbench, fixing it with clamps, and then manually inserting the bearings and mounting rings into their corresponding installation positions on the bracket mold. Finally, a nylon hammer is used to complete the pre-installation and tightening. This installation method has drawbacks, such as inconvenient operating position during the hammering pre-installation process and the risk of injury; the hammering tightening process can cause flying debris to scratch the face; manual hammering is slow, resulting in uneven stress on the bearings and mounting rings and compromising quality; manual hammering is noisy and has high labor costs. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a bracket mold bearing and mounting ring assembly device and method, which can automatically assemble the bearing and mounting ring on the bracket mold, thereby improving product quality, reducing costs, and reducing installation noise.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bracket mold bearing and mounting ring assembly device, comprising a frame, on which are mounted:

[0005] The positioning seat and the bracket mold are mounted on the positioning seat. The bracket mold is provided with bearing mounting holes and mounting ring mounting holes.

[0006] The camera captures images to determine the positions of the bearing mounting holes and the mounting ring mounting holes.

[0007] The bearing assembly unit includes a bearing clamp arm and a bearing push rod. The bearing clamp arm holds the bearing to the bearing mounting hole position, and the bearing push rod moves to push the bearing into the bearing mounting hole.

[0008] The mounting ring assembly unit includes a mounting ring clamping arm and a mounting ring pusher. The mounting ring clamping arm holds the mounting ring to the mounting ring mounting hole position, and the mounting ring pusher moves to push the mounting ring into the mounting ring mounting hole.

[0009] During the assembly of bearings and mounting rings on the bracket mold, the bracket mold is first loaded onto the positioning seat. After the bracket mold and the positioning seat are in their relative positions, the positioning seat is moved to the corresponding positions of the bearing assembly unit and the mounting ring assembly unit. Once in position, a camera is used to capture and determine the precise positions of the bearing mounting holes and mounting ring mounting holes, ensuring the coaxiality of the bearing mounting holes, bearing, and bearing push rod, as well as the coaxiality of the mounting ring mounting holes, mounting ring, and mounting ring push rod, thus ensuring assembly accuracy. Then, the bearing clamping arm holds the bearing to the bearing mounting hole position, and the bearing push rod moves to push the bearing into the bearing mounting hole; similarly, the mounting ring clamping arm holds the mounting ring to the mounting ring mounting hole position, and the mounting ring push rod moves to push the mounting ring into the mounting ring mounting hole. The installation of the bearing and mounting ring is achieved through the pushing action of the bearing push rod and the mounting ring push rod, eliminating the need for hammering and avoiding noise generated by hammering. This invention automatically assembles the bearings and mounting rings on the bracket mold, which is beneficial for improving product quality, reducing costs, and reducing installation noise.

[0010] Preferably, a pair of bearing grippers are provided on the bearing clamp arm, and the two bearing grippers move close to each other to grip the bearing.

[0018] Preferably, the frame is equipped with two push motors and two slides. The output shaft of the push motor is connected to the push screw. The slide is adapted to the push screw. The frame is equipped with push rails corresponding to the slides. The slides are slidably mounted on the push rails. The bearing push rod and the mounting ring push rod are respectively connected to the two slides.

[0019] The motor drives the screw to rotate, which in turn moves the slide along the slide rail. This causes the bearing push rod and the mounting ring push rod to move together with the two slides. During the movement, the bearing push rod pushes the bearing into the bearing mounting hole, and the mounting ring push rod pushes the mounting ring into the mounting ring mounting hole.

[0020] Preferably, a lifting seat that can be raised and lowered is provided on the frame and corresponding to the drive motor, and the drive slide rail and drive motor are mounted on the lifting seat.

A clamping arm seat that can move along the Z-axis is installed on the Z-axis guide rail, and the bearing clamping arm and the mounting ring clamping arm are respectively installed on the two clamping arm seats.

[0023] This structural design enables the clamping arm to move along the Y and Z axes, thereby allowing both the bearing clamping arm and the mounting ring clamping arm to move along the Y and Z axes.

[0060] S4, the Y-axis motor 39 and Z-axis motor 41 operate, causing the bearing clamp arm 18 and the mounting ring clamp arm 21 to move to the bearing loading frame 53 and the mounting ring loading frame 54 respectively. The robotic arm linkage mechanism operates to clamp the bearing and the mounting ring. The bearing clamp arm 18 clamps the bearing to the bearing mounting hole 6, and the motor 43 drives the bearing push rod 19 to move and push the bearing into the bearing mounting hole 6. The mounting ring clamp arm 21 clamps the mounting ring to the mounting ring mounting hole 7, and the motor 43 drives the mounting ring push rod 22 to move and push the mounting ring into the mounting ring mounting hole 7.

[0061] S5, the bearing and mounting ring are assembled, the positioning seat 3 is moved outward, and the bracket mold 5 is removed.

[0062] The assembly of the bearing and mounting ring on the bracket mold 5 can be completed automatically. First, the positions of the bearing mounting hole 6 and the mounting ring mounting hole 7 are accurately positioned. Then, the bearing clamping arm 18 and the mounting ring clamping arm 21 are used to clamp the bearing and the mounting ring respectively. The bearing is transferred between the bearing mounting hole 6 and the bearing push rod 19, and the mounting ring is transferred between the mounting ring mounting hole 7 and the mounting ring push rod 22. Through the movement of the bearing by the bearing push rod 19 and the mounting ring push rod 22, the bearing is pushed and installed into the bearing mounting hole 6, and the mounting ring is pushed and installed into the mounting ring mounting hole 7.

[0063] Example 2: A bracket mold bearing and mounting ring assembly device includes a frame 1, on which are mounted a positioning seat 3, a camera 4, a bearing assembly unit, and a mounting ring assembly unit. A bracket mold 5 is mounted on the positioning seat 3, and the bracket mold 5 has bearing mounting holes 6 and mounting ring mounting holes 7. An X-axis screw 8 and two X-axis slide rails 9 are correspondingly provided on the frame 1 and the positioning seat 3. An X-axis motor 10 is mounted on one end of the X-axis screw 8 on the frame 1, and the output shaft of the X-axis motor 10 is connected to the X-axis screw 8. A screw hole is provided on the positioning seat 3, which is adapted to the X-axis screw 8. The positioning seat 3 is slidably connected to the two X-axis slide rails 9. The X-axis motor 10 drives the X-axis screw 8 to rotate, thereby causing the positioning seat 3 to slide along the X-axis slide rails 9. Two positioning strips 11 are mounted on the positioning seat 3, and the front and rear sides of the bracket mold 5 are respectively supported on the two positioning strips 11. The bracket mold 5 and the positioning seat 3 are fastened together by connecting parts. Several positioning supports 12 are connected to the upper surface of the positioning seat 3, and the bracket mold 5 is supported on the positioning supports 12.

[0064] Camera 4 captures images to determine the positions of bearing mounting hole 6 and mounting ring mounting hole 7. A mounting base 13 and a sliding rail 14 are correspondingly installed on the frame 1. Camera 4 is mounted on the mounting base 13, which is slidably mounted on the sliding rail 14. A sliding screw 15, driven by a sliding motor 17, is installed above the sliding rail 14. A sliding sleeve 16 is securely connected to the mounting base 13, and the sliding screw 15 and sliding sleeve 16 are fitted together. The sliding motor 17 drives the sliding screw 15 to rotate, thereby adjusting the position of camera 4.

[0065] The bearing assembly unit includes a bearing clamp arm 18 and a bearing push rod 19. The bearing clamp arm 18 holds the bearing to the bearing mounting hole 6, and the bearing push rod 19 moves to push the bearing into the bearing mounting hole 6. A pair of bearing jaws 20 are provided on the bearing clamp arm 18, and the two bearing jaws 20 move close to each other to grip the bearing.

[0066] As attached Figure 5 As shown, several straightening rods 57 are evenly distributed at the end of the bearing push rod 19. An inclined guide surface 58 is provided on the outer wall of the end of each straightening rod 57. The straightening rods 57 are evenly distributed along the circumference of the bearing inner ring, and their outer walls are in contact with the inner wall of the bearing inner ring. During bearing installation, before the end of the bearing push rod 19 contacts the bearing, the straightening rods 57 are first inserted into the bearing inner ring. When there is a deviation in the bearing position, the guide surface 58 contacts the edge of the bearing inner ring, correcting the bearing's deviation as the bearing push rod 19 moves towards the bearing, ensuring the bearing is accurately installed in the bearing mounting hole 6.

[0067] The mounting ring assembly unit includes a mounting ring clamping arm 21 and a mounting ring push rod 22. The mounting ring clamping arm 21 clamps the mounting ring to the mounting ring mounting hole 7, and the mounting ring push rod 22 moves to push the mounting ring into the mounting ring mounting hole 7. A pair of mounting ring clamping claws 23 are provided on the mounting ring clamping arm 21, and the two mounting ring clamping claws 23 move close to each other to grasp the mounting ring.

[0068] As attached Figure 6 Appendix Figure 7 As shown, the mounting ring has a notch 59, and its outer wall is an arc shape with the notch 59. The inner wall of the mounting ring is U-shaped. The end of the mounting ring push rod 22 is equipped with two outer circular clamping rods 60, two inner circular clamping rods 61, and two side wall clamping rods 62. The inner surface of the outer circular clamping rods 60 has an inclined outer pushing surface 63, and the outer surfaces of the inner circular clamping rods 61 and the side wall clamping rods 62 have inclined inner pushing surfaces 64. The outer circular clamping rods 60 are clamped onto the outer wall of the mounting ring, the inner circular clamping rods 61 are clamped onto the arc-shaped inner wall of the mounting ring, and the side wall clamping rods 62 are clamped onto the planar inner wall of the mounting ring. This clamping action achieves precise positioning of the mounting ring. When the mounting ring deviates from its position, the outer pushing surface 63 and the inner pushing surface 64 can correct the deviation and adjust the mounting ring to the precise position.

[0069] Mounting holes 65 are provided on the mounting ring push rod 22 corresponding to the outer circular clamp rod 60. One end of the outer circular clamp rod 60 is installed in the mounting hole 65. A preload spring 66 is installed between the front side of the mounting hole 65 and the outer circular clamp rod 60. A return spring 67 is connected to the rear end of the outer circular clamp rod 60. A positioning pin 68 is installed on the hole wall of the mounting hole 65. A positioning spring 69 is installed between the positioning pin 68 and the mounting ring push rod 22. The positioning pin 68 abuts against the rear end of the outer circular clamp rod 60 to position the outer circular clamp rod 60. A drive rod 70 is installed on the mounting ring push rod 22. The front end of the drive rod 70 extends out of the end face of the mounting ring push rod 22. A return spring 71 is installed between the drive rod 70 and the mounting ring push rod 22. An inclined push surface 72 is provided on the drive rod 70. A push post 73 is provided on the positioning pin 68. The push surface 72 can abut against the push post 73 to retract the positioning pin 68.

[0070] During the process of pushing the mounting ring push rod 22 towards the mounting ring, the outer circular clamping rod 60 first clamps onto the outer wall of the mounting ring. As the mounting ring push rod 22 continues to push forward, the end of the drive rod 70 abuts against the end face of the mounting ring, causing the drive rod 70 to move backward. This, in turn, pushes the positioning pin 68 back, at which point the positioning pin 68's positioning effect on the outer circular clamping rod 60 disappears, allowing the outer circular clamping rod 60 to move backward until the mounting ring is pushed into the mounting hole 7. After installation, the mounting ring push rod 22 returns to its original position. Under the action of the return spring 67, the front end of the mounting ring push rod 22 extends beyond its end. At this point, pulling the outer circular clamping rod 60 outward by hand will return it to its original position.

[0071] Both the bearing clamping arm 18 and the mounting ring clamping arm 21 are equipped with a robotic arm linkage mechanism.
