Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing shaft assembly technology, and in particular to an automatic material handling and pre-compression assembly mechanism for shaft end retaining rings. Background Technology
[0002] Currently, when manufacturing automotive bearings, it is usually necessary to install retaining rings on the bearing rod. In existing technologies, the retaining rings are usually placed manually and then pressed in, which is relatively inefficient.
[0003] Application No. 2019108625009 discloses an automatic assembly device for a three-pronged bearing retainer. By using a telescopic cylinder to drive the retainer loading platform to move horizontally, the retainer placement slot is pushed to the bearing rod. Then, a pushing cylinder pushes the retainer onto the bearing rod. Finally, an installation cylinder drives the retainer installation head to press down to complete the installation action. The retainer installation is completed automatically without manual intervention, which greatly improves the convenience of processing.
[0004] However, during the press-fitting process, the retaining ring needs to be expanded to a certain size before being pressed into the retaining ring groove of the bearing rod. In the existing technology, the retaining ring is directly pressed onto the bearing rod. Direct press-fitting cannot effectively control the expansion process, which can easily lead to damage to the retaining ring and affect product quality. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose an automatic material handling and pre-pressing assembly mechanism for shaft end retaining rings, so as to solve the problem that direct pressing can easily cause damage to the retaining rings.
[0006] To achieve the above objectives, this utility model provides an automatic material handling and pre-compression assembly mechanism for shaft end retaining rings, including a frame, a transverse slide rail on one side of the frame, a movable frame slidably mounted on the transverse slide rail, a longitudinal slide rail on the movable frame, an mounting bracket slidably mounted on the longitudinal slide rail, a material clamping mechanism on one side of the mounting bracket for clamping and placing the retaining ring, a pre-compression mechanism at the lower end of the mounting bracket for pre-compressing the retaining ring placed on the material feeding mechanism, a feeding mechanism at one end of the frame for feeding material onto the material clamping mechanism, and a placement seat for placing bearing rods at the other end of the frame.
[0007] A further improvement is that the clamping mechanism includes a shaft core, a lifting plate is slidably mounted on the side of the mounting bracket via a guide rail, the shaft core is connected to the lower side of the lifting plate, a lifting cylinder is mounted on the upper end of the mounting bracket, and the output end of the lifting cylinder is connected to the lifting plate.
[0008] A further improvement is that the middle of the shaft core is a frustum structure, and the upper and lower ends of the shaft core are cylindrical structures.
[0009] A further improvement is that the pre-compression mechanism includes a pressure head seat that is bolted to the lower end of the mounting bracket, with a pressure head rotatably connected to the lower side of the pressure head seat, and multiple sets of pressure heads arranged around the circumference.
[0010] A further improvement is that the feeding mechanism includes a feeding seat, a feeding groove is provided in the middle of the feeding seat, the feeding groove has openings on both sides at the lower end, a pushing cylinder is provided on one side of the feeding seat, and a pushing plate is installed at the output end of the pushing cylinder. The pushing cylinder drives the pushing plate to extend from the opening on one side and push the retaining ring out from the opening on the other side to feed the material.
[0011] A further improvement is that a guide plate is installed on the other side of the feeding seat to guide the feeding and engagement of the retaining ring.
[0012] The beneficial effects of this utility model are as follows: By setting a clamping mechanism for placing and opening the retaining ring, the retaining ring is gradually opened by the shaft core. The shaft core adopts a structure that is smaller at the top and larger at the bottom, with cylindrical structures at the top and bottom and a frustum structure in the middle. The retaining ring is clamped to the upper end of the shaft core by the feeding mechanism. The pre-pressing mechanism pushes the retaining ring down along the frustum structure in the middle of the shaft core, gradually opening the retaining ring during the downward movement. Finally, the cylindrical mechanism at the lower end of the shaft core keeps the retaining ring in an open state. Through the docking of the shaft core and the bearing rod, the pre-pressing mechanism can stably push and clamp the opened retaining ring into the retaining ring groove on the bearing rod, which greatly improves the convenience of assembly, reduces the occurrence of retaining ring damage, and improves product quality.

[0018] like Figure 1-5 As shown, this embodiment provides an automatic material handling and pre-compression assembly mechanism for shaft end retaining rings, including a frame 1. A transverse slide rail 2 is provided on one side of the frame 1, and a movable frame 3 is slidably mounted on the transverse slide rail 2. The movable frame 3 is driven by a movable motor to slide on the transverse slide rail 2. A longitudinal slide rail 4 is provided on the movable frame 3, and an mounting bracket 5 is slidably mounted on the longitudinal slide rail 4. The mounting bracket 5 is driven by a movable motor to slide on the longitudinal slide rail 4. A material clamping mechanism is provided on one side of the mounting bracket 5 to clamp and place the retaining ring. A feeding mechanism is provided at one end of the frame 1 to feed material onto the material clamping mechanism. A placement seat for placing bearing rods is provided at the other end of the frame 1. The movable frame 3 moves on the transverse slide rail 2, and the electric material clamping mechanism of the movable frame 3 moves to the feeding mechanism to feed the retaining ring. The movable frame 3 moves to the placement seat to assemble the retaining ring clamped on the material clamping mechanism onto the bearing rod placed on the placement seat.
[0019] The clamping mechanism includes a shaft core 6. A lifting plate 8 is slidably mounted on the side of a mounting bracket 5 via a guide rail. The shaft core 6 is connected to the lower side of the lifting plate 8. A lifting cylinder 7 is mounted on the upper end of the mounting bracket 5, and the output end of the lifting cylinder 7 is connected to the lifting plate 8. The middle of the shaft core 6 is a frustum structure, and the upper and lower ends of the shaft core 6 are cylindrical structures. The diameter of the upper cylindrical structure of the shaft core 6 is smaller than that of the lower cylindrical structure. The upper cylindrical structure of the shaft core 6 is used for the initial clamping ring engagement, the lower cylindrical structure of the shaft core 6 is used for the open clamping ring engagement, and the frustum structure in the middle of the shaft core 6 is used for the gradual opening of the clamping ring.
[0020] A pre-compression mechanism is provided at the lower end of the mounting bracket 5. The pre-compression mechanism pre-compresses the retaining ring placed on the feeding mechanism. The pre-compression mechanism includes a pressure head seat 9 bolted to the lower end of the mounting bracket 5. A pressure head 10 is rotatably connected to the lower side of the pressure head seat 9. The pressure head 10 can be rotatably connected to the pressure head seat 9 via a torsion spring shaft. Multiple sets of pressure heads 10 are arranged around the circumference. As the lifting cylinder 7 moves the shaft core 6 upward through the lifting plate 8, the pressure head 10 pushes down the retaining ring that is engaged on the upper cylinder of the shaft core 6. As the diameter of the shaft core 6 increases, the pressure head 10 gradually rotates and unfolds outward, pushing the retaining ring to gradually open along the frustum structure in the middle of the shaft core 6. Finally, the retaining ring engages on the lower cylinder of the shaft core 6, facilitating subsequent press-fit assembly.
[0021] The feeding mechanism includes a feeding seat 11, with a feeding groove 12 in the middle of the feeding seat 11. The feeding groove 12 has openings on both sides at its lower end. A pushing cylinder 13 is provided on one side of the feeding seat 11. A pushing plate 14 is installed at the output end of the pushing cylinder 13. The pushing cylinder 13 drives the pushing plate 14 to extend from the opening on one side and push the retaining ring out from the opening on the other side to feed the material. A guide plate 15 is installed on the other side of the feeding seat 11. The guide plate 15 guides the feeding and engagement of the retaining ring. The end of the guide plate 15 has a notch that matches the shaft core 6. When the retaining ring is fed, the lifting cylinder 7 drives the lifting plate 8 to move down, causing the shaft core 6 to move down. Then, the moving frame 3 moves on the transverse slide rail 2, causing the shaft core 6 to move into the notch at the end of the guide plate 15. The pushing cylinder drives the pushing plate 14 to push the retaining ring from the discharge groove 12 to the guide plate 15, and moves along the guide plate 15 and engages with the shaft core 6.
[0022] During production, the retaining rings are positioned and stacked in the placement groove, and the bearing rods are placed on the placement seat. The moving frame 3 slides on the transverse slide rail 2 to one side of the loading seat 11. The lifting cylinder 7 drives the shaft core 6 to move down through the lifting plate 8, so that the shaft core 6 is engaged with one end of the guide plate 15. The pushing cylinder 13 pushes the retaining ring out of the placement groove through the pushing plate 14, and the guide plate 15 guides it to engage with the shaft core 6. After loading is completed, the moving frame 3 moves towards the placement seat on the transverse slide rail 2, while the lifting cylinder 7 drives the shaft core 6 to move up through the lifting plate 8. The pressure head 10 pushes the retaining ring on the shaft core 6 to move towards the lower end of the shaft core 6, so that the retaining ring is engaged at the lower end of the shaft core 6; the moving frame 3 drives the shaft core 6 to move above the bearing rod, the mounting bracket 5 slides downward on the longitudinal slide rail 4, and the shaft core 6 is attached to the upper end of the bearing rod. As the mounting bracket 5 continues to move downward, the shaft core 6 causes the lifting plate 8 to slide upward through the push of the bearing rod. The pressure head 10 pushes the retaining ring from the shaft core 6 into the retaining ring groove on the bearing rod for installation. After the retaining ring is stably opened, the assembly is carried out, which greatly improves the assembly quality.
