Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] As attached Figures 1 to 3A high-precision automatic fitting device for a hub unit bearing is shown, comprising a base 1, which is made of metal material and plays a supporting and protective role. A fitting mechanism 2 is arranged at the upper center of the base 1, and a control panel 3 is arranged below the fitting mechanism 2. The control panel 3 can enable the fitting mechanism 2 to perform automatic fitting operations on materials, and enable the No. 2 manipulator 11 to accurately clamp the fitted bearing and place it on the No. 1 conveying mechanism 5 below, so as to realize automated production and improve work efficiency. A support frame 4 is arranged on one side of the control panel 3, and a No. 1 conveying mechanism 5 is arranged on one side of the support frame 4. The support frame 4 is made of metal material and plays a role of supporting the fitting mechanism 2. At the same time, a stable horizontal platform is provided at the bottom, so that the No. 1 conveying mechanism 5 can transport the bearing forward smoothly.

[0023] A No. 1 robot 6 is arranged on one side of the No. 1 conveying mechanism 5. The manufacturing material of the robot needs to have the characteristics of light weight, high strength and corrosion resistance to ensure its stability and durability. Commonly used materials include aluminum alloy, titanium alloy, carbon fiber, etc., and a multi-joint structure is usually adopted. Each joint has a certain degree of freedom and can realize flexible movement. This design enables the robot to move and operate accurately and quickly in a complex working environment.

[0024] A No. 2 conveying mechanism 7 is arranged on one side of the sleeve mechanism 2. The No. 2 conveying mechanism 7 is provided with two groups, and the two groups of No. 2 conveying mechanisms 7 are arranged alternately in the horizontal direction of the base 1. The No. 1 conveying mechanism 5 and the No. 2 conveying mechanism 7 include a driving wheel 8 and a magnetic conveyor belt 9. The magnetic conveyor belt 9 is a metal material conveyor belt with an electromagnetic positioning point. The material of the magnetic conveyor belt 9 needs to have good electromagnetic permeability to ensure that the electromagnetic field can penetrate smoothly and generate adsorption force on metal objects. The electromagnetic positioning point of this design generates adsorption force on the metal objects placed thereon through the action of the electromagnetic field, thereby achieving precise positioning. This positioning method has the characteristics of fast response speed and high positioning accuracy. A fixing rod 10 is arranged on the side of the No. 2 conveying mechanism 7 close to the sleeve mechanism 2. The fixing rod 10 is made of metal material, so that the No. 2 manipulator 11 can be fixed in position to ensure that the horizontal position remains unchanged and high precision is guaranteed. The No. 2 manipulator 11 is arranged at one end of the fixing rod 10, and a camera 12 is arranged on one side of the No. 2 manipulator 11. The model of the camera 12 is FL IR Fi ref ly series, this camera 12 can integrate the camera and the visual processing unit (VPU) to provide enhanced functions, enabling the second robot 11 to identify the location of the material and achieve higher precision clamping and placement.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 3As shown, see the following description for details:

[0027] As a preferred embodiment, the sleeve mechanism 2 includes a slide rail 13, a sliding plate 14 and a limit plate 15. The outer wall of the slide rail 13 is provided with a sliding plate 14. There are two groups of sliding plates 14, and the two groups of sliding plates 14 are symmetrically arranged along the slide rail 13. A limit plate 15 is provided on one side of the sliding plate 14, and the position of the bearing is fixed by the limit plate 15. Furthermore, the sleeve mechanism 2 drives the middle bearing to be sleeved by the displacement of the two groups of sliding plates 14 on the slide rail 13. This design is simple and efficient. At the same time, the limit plate 15 is made of metal material, which can limit the displacement of the bearing and ensure the accuracy of the sleeve.

[0028] As a preferred embodiment, the No. 1 manipulator 6 can place the bearing that has been assembled by the assembly mechanism 2 on the No. 1 conveying mechanism 5. A cargo box 16 is provided on one side of the No. 1 conveying mechanism 5. Furthermore, the No. 1 manipulator 6 places the bearing into the No. 1 conveying mechanism 5 to realize a highly automated production process, reduce labor costs, and improve work efficiency.

[0029] As a preferred embodiment, the transport directions of the two groups of No. 2 conveying mechanisms 7 are opposite. A No. 3 robot 17 is set on one side of the No. 2 conveying mechanism 7. The No. 3 robot 17 can place the material on the No. 2 conveying mechanism 7. Furthermore, two No. 2 conveying mechanisms 7 are used to run in opposite directions, so that the material can be transported from both ends to the center. This layout makes full use of the space and improves production efficiency. No. 3 robots 17 are arranged at both ends of the No. 2 conveying mechanism 7, which are responsible for placing the material accurately on the magnetic conveyor belt 9 to ensure the stability and accuracy of the material during the transportation process.

[0030] As a preferred embodiment, the No. 2 conveying mechanism 7 is connected to the transmission gear 18 through the driving wheel 8, and one side of the two sets of transmission gears 18 is connected to the motor 19. Furthermore, the motor 19 provides kinetic energy for the No. 2 conveying mechanism 7, so that the two sets of conveying mechanisms can operate synchronously, ensuring that the material transmission speed is the same.

[0031] As a preferred embodiment, the camera 12 can determine the position of the material, and place the material on the limit plate 15 after accurately clamping it through the second robot 11. Furthermore, the image captured in real time by the camera 12 and the image information processed by the processor can accurately guide the operation of the second robot 11, improve the accuracy of operations such as fitting and positioning, and reduce manual operation time by optimizing the operating process, thereby improving overall production efficiency.

[0032] The working process of the utility model is as follows: first, the third manipulator 17 automatically places the bearings of the two-part hub unit from both sides onto the second conveying mechanism 7. The magnetic conveyor belt 9 of the conveying mechanism adopts a special design with an electromagnetic positioning point. When the bearing is placed on the magnetic conveyor belt 9, the electromagnetic positioning point acts on the bearing to fix it in a specific position to ensure stability and accuracy during transportation. A closing mechanism 2 is provided at the intersection of the two sets of second conveying mechanisms 7. Two sets of second manipulators 11 are provided next to the closing mechanism 2. These manipulators place the second conveying mechanism 7 The delivered bearing is accurately removed and placed in the corresponding position of the fitting mechanism 2. The fitting mechanism 2 drives the middle bearing to fit through the displacement of the two sets of sliding plates 14 on the slide rail 13. This process needs to ensure the alignment and embedding accuracy of the bearing to achieve correct fitting. After the fitting is completed, the No. 1 robot 6 on the side removes the bearing and places it on the No. 1 conveying mechanism 5 below. This set of conveyor belts sends the fitted bearings into the cargo box 16 for subsequent packaging process. The above is the working principle of this high-precision automatic fitting device for hub unit bearings.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
