Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution:
[0021] An automatic disassembly and assembly mechanism for the inner ring and outer assembly of a bus bearing includes a mounting base 3. A combined outer assembly 1 for disassembling and assembling the inner ring and outer assembly of the bearing is mounted on the surface of the mounting base 3. Inside the mounting base 3 below the combined outer assembly 1, a displacement component 2 is provided to sequentially transport the inner ring and outer assembly of the bearing to the bottom of the combined outer assembly 1. The displacement component 2 accurately transports the inner ring and outer assembly of the bearing to the bottom of the combined outer assembly 1, and then the combined outer assembly 1 completes the disassembly and assembly operation, realizing an automated disassembly and assembly process and greatly improving work efficiency.
[0022] Displacement component 2: The displacement component 2 includes linear guide rails 209 mounted on both sides of the top of the mounting base 3. Two sliding seats 212 are slidably mounted on the bottom of the linear guide rails 209. The linear guide rails 209 provide stable guidance for the sliding seats 212, ensuring accurate displacement. The bottom of each sliding seat 212 is provided with a U-shaped fitting displacement plate 203. This U-shaped design facilitates connection and cooperation with other components while reducing its own weight. The bottom sides of the fitting displacement plate 203 are connected to lifting cylinder fixing plates 205 via movable support shafts 206. The connection structure is stable, ensuring the coordinated operation of all components. To ensure reliability, a lifting cylinder 202 is installed at the middle of the bottom end of the lifting cylinder fixing plate 205. The lifting cylinder 202 provides vertical power to control the lifting of the bearing positioning plate 201. The top of the lifting cylinder 202 extends through and above the sleeve displacement plate 203 and connects to the bearing positioning plate 201. The bearing positioning plate 201 is used to accurately position the inner ring and outer component of the bearing, facilitating subsequent disassembly and assembly operations. Linear bearings 204 are installed inside the lifting cylinder fixing plates 205 on both sides of the lifting cylinder 202. A displacement guide shaft 207 is sleeved inside the linear bearing 204. The linear bearing 204 and the displacement guide shaft 207 are matched... This further ensures the stability and accuracy of the lifting cylinder fixing plate 205 during the lifting process. The bottom end of the displacement guide shaft 207 is located on the bottom side of the lifting cylinder 202 and connected to the displacement shaft connecting plate 208. The top end of the displacement guide shaft 207 is also located on the bottom end of the bearing positioning plate 201. The two sliding seats 212 are connected by a displacement connecting plate 218. A displacement cylinder pull head 215 is installed at the bottom end of the displacement connecting plate 218. The side of the displacement cylinder pull head 215 is connected to a displacement cylinder seat 213 through a buffer head 214. The displacement cylinder seat 213 is connected to a displacement cylinder fixing plate 210 through a displacement cylinder 211. The displacement cylinder... The top of the cylinder fixing plate 210 is fixed to the top of the inner part of the mounting base 3. The displacement cylinder 211 drives the sliding seat 212 to slide on the linear guide rail 209 through the displacement cylinder pull head 215, thereby realizing the horizontal displacement of the displacement component 2. The buffer head 214 plays a buffering role to reduce the impact during the displacement process. The bottom of the mounting base 3 away from the displacement cylinder fixing plate 210 is equipped with a displacement buffer seat 216. The side of the displacement buffer seat 216 is equipped with a buffer head 217 at the position corresponding to the displacement cylinder pull head 215. When the displacement cylinder pull head 215 moves to the limit position, the buffer head 217 contacts the displacement cylinder pull head 215, further playing a buffering and protection role.
[0023] Outer Assembly 1: The outer assembly 1 includes guided linear bearings 102 distributed on the surfaces of mounting bases 3 on both sides of the displacement assembly 2. A guide rod 114 is slidably mounted inside the guided linear bearing 102. The bottom end of the guide rod 114 is located at the top of the mounting base 3. A lifting fixing plate 113 is mounted at the top of the guide rod 114. The cooperation between the guided linear bearing 102 and the guide rod 114 provides stable guidance for the lifting and lowering of the lifting fixing plate 113. A lifting base plate 104 capable of supporting the outer assembly is mounted at the bottom end of the linear bearing 102. A positioning cylinder 108 is mounted at the middle position of the surface of the lifting fixing plate 113. The bottom end of the positioning cylinder 108 is located below the lifting fixing plate 113 and connected to a positioning mounting plate 112. The positioning cylinder 108 is used to control the lifting and lowering of the positioning mounting plate 112, thereby realizing the positioning operation of the bearing inner ring and the outer assembly. Linear bearings 109 are installed inside the lifting and fixing plates 113 on both sides of the positioning cylinder 108. A positioning guide shaft 110 is slidably installed inside the linear bearing 109. The linear bearing 109 and the positioning guide shaft 110 ensure the stability of the positioning mounting plate 112 during the lifting process. The top ends of the positioning guide shaft 110 are connected by a positioning lifting shaft connecting plate 111. The bottom end of the positioning guide shaft 110 is set on the surface of the positioning mounting plate 112. Lifting cylinders 107 are installed on both sides of the surface of the lifting and fixing plate 113. A floating joint 106 is connected to the bottom end of the lifting cylinder 107. The bottom end of the floating joint 106 is connected to the surface of the lifting base plate 104 through a connecting rod 105. The lifting cylinder 107 drives the lifting base plate 104 to rise and fall through the floating joint 106 and the connecting rod 105, realizing the lifting of the bearing outer components and other operations to complete the disassembly and assembly work.
[0024] Working process of displacement component 2
[0025] Horizontal displacement: When it is necessary to transport the bearing inner ring and outer assembly to below the outer assembly 1, the displacement cylinder 211 is activated. The displacement cylinder 211 pushes the displacement cylinder seat 213. The displacement cylinder seat 213 drives the displacement cylinder pull head 215 to move through the buffer head 214. The displacement cylinder pull head 215 drives the two sliding seats 212 to slide on the linear guide rail 209 through the displacement connecting plate 218, thereby realizing the horizontal displacement of the assembly displacement plate 203 and its connecting parts, and transporting the bearing inner ring and outer assembly on the bearing positioning plate 201 to the designated position. When the displacement cylinder pull head 215 moves to the side close to the displacement buffer seat 216, the buffer head 217 contacts the displacement cylinder pull head 215, which plays a buffering role and prevents the displacement assembly from being damaged due to inertia.
[0026] Vertical displacement: After the bearing inner ring and outer assembly are transported to the designated position, the lifting cylinder 202 is activated, the piston rod of the lifting cylinder 202 extends, and pushes the bearing positioning plate 201 to rise, raising the bearing inner ring and outer assembly to a suitable height so that the outer assembly 1 can be assembled and operated. During the lifting process, the linear bearings 204 on both sides of the lifting cylinder fixing plate 205 slide along the displacement guide shaft 207, ensuring the stability and accuracy of the lifting process.
[0027] Working process of outer component 1
[0028] Lifting the outer component: After the bearing inner ring and the outer component are transported to a suitable position below the outer component 1 by the displacement component 2, the lifting cylinder 107 is activated, the piston rod of the lifting cylinder 107 extends, and drives the lifting base plate 104 to rise through the floating joint 106 and the connecting rod 105. The lifting base plate 104 lifts the bearing outer component upward. During the lifting process, the guide rod 114 slides in the guide linear bearing 102 to ensure the stability of the lifting base plate 104 during the rising process.
[0029] Positioning operation: During or after lifting the outer component, the positioning cylinder 108 is activated, the piston rod of the positioning cylinder 108 extends, and pushes the positioning mounting plate 112 down. The positioning mounting plate 112 maintains a stable descent process through the positioning guide shaft 110 and the positioning lifting shaft connecting plate 111, positioning the bearing inner ring and the outer component so as to perform precise disassembly or assembly operations.
[0030] Disassembly and assembly operations: After completing the positioning and lifting preparations, the disassembly or assembly of the inner ring and outer component of the bus bearing is achieved through the further action of the lifting cylinder 107 and the coordinated operation of other related components. For example, during assembly, the inner ring of the bearing is placed on the bearing positioning plate 201, and it is transported to the underside of the outer component 1 by the displacement component 2. The lifting base plate 104 lifts the outer component of the bearing and precisely aligns it with the inner ring of the bearing to complete the assembly. During disassembly, the outer component of the bearing is lifted by the lifting base plate 104 to separate it from the inner ring of the bearing to complete the disassembly operation.
