Description

Technical Field

[0001] The invention belongs to the technical field of disassembly and transportation, and in particular relates to a disassembly type loading and unloading mechanism. Background Art

[0002] The disassembly loading and unloading mechanism is a mechanism used to switch, disassemble and move workpieces in automated production. When the device receives a loading or unloading signal, the control part will respond according to the preset program, the clamping device will clamp the workpiece, and then the disassembly and assembly operation will be performed through the disassembly and assembly tools (such as disassembly and assembly pieces). The transmission part will drive these tools to move to realize the disassembly and assembly and movement of the workpiece. After the disassembly and assembly operation is completed, the clamping device will release the workpiece, place it at the specified position or on the tray, and complete the disassembly and loading and unloading.

[0003] The disassembly loading and unloading mechanism can disassemble a wide range of materials in automated production, including but not limited to workpieces, parts, components, etc. of various shapes. Some materials with holes may need to be stretched into the holes during the disassembly process, especially for the disassembly of bearings. The bearings have inner and outer rings and rolling elements, which are connected together by a retaining frame. When disassembling and assembling bearings with interference fit of the inner ring, the force cannot be transmitted to the inner ring through the outer ring and the rolling element, which will damage the bearing raceway and the rolling element surface, causing the bearing to produce noise during operation and premature damage. Therefore, bearing disassembly generally requires staff to use mechanical pullers or knocking methods to disassemble and assemble the bearings, while traditional equipment directly knocks on the inner ring and the outer ring end face of the bearing, which can easily damage the bearing, making the bearing after loading and unloading unable to meet the product qualification line.

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

[0033] like Figure 1-8 A disassembly loading and unloading mechanism shown in the figure includes a conveying platform 1, a limit support 2, a knocking cylinder 3, a pushing component 4, an inner ring fitting component 5, a clamping component 6, a disassembly and assembly positioning component 7 and a feeding component 8.

[0034] The conveying platform 1 is used to convey the bearing, the limiting support 2 is used to support the pushing component 4, the pushing component 4 is used to push the knocking tube 3 to impact the inner ring of the bearing, the inner ring fitting component 5 is used to extend into the inner ring of the bearing and rest against the inner side of the gap between the inner ring of the bearing and the bearing roller, the clamping component 6 is used to place the outer ring and the inner ring of the bearing on the opposite sides of the disassembly and positioning component 7 and the inner ring fitting component 5 respectively, the disassembly and positioning component 7 is used to clamp the outer ring of the bearing, and the loading component 8 is used to load the disassembled bearing components.

[0035] The curved hook block 10 is firmly locked in the precise position between the inner ring of the bearing and the roller by rotating the knocking block, which not only effectively prevents displacement or loosening that may occur during operation, but also its unique design allows the hook block to be flexibly hung in the gap of the component. This feature not only provides additional support for the entire structure and significantly enhances the stability of the connection, but also greatly simplifies the disassembly and assembly process. During installation, the staff can operate more conveniently and can install and disassemble the hook block without complicated tools or too much time, thereby improving work efficiency and reducing maintenance costs.

[0036] The inner ring fitting assembly 5 includes an insertion pillar 9, a curved hook block 10, an inner ring support plate 11 and an electric telescopic rod 12.

[0038] The arc-shaped sleeve 19 is firmly clamped on the outer ring of the bearing, ensuring the stability and safety of the operation. At this time, the heavy-duty oil cylinder 14 exerts its powerful thrust to drive the thick rod 15 to move linearly, thereby pushing the sliding sleeve 16 and the knocking cylinder 3 to precisely position. The knocking cylinder 3 acts directly on the inner ring of the bearing and uses its precise knocking force to perform the separation operation. The inner ring abutment plate 11 has been tightly fitted on the inner surface of the inner ring in advance, and continues to push the inner ring outward during the knocking process. This design greatly reduces the force required for knocking, allowing the knocking cylinder 3 to more easily, efficiently and accurately separate the inner ring from the installation position of the bearing retainer. Since the force transmission is direct and efficient throughout the process, unnecessary energy consumption and mechanical wear are reduced, and the service life of the bearing is extended.

[0040] The disassembly and assembly positioning assembly 7 includes a disassembly and assembly bracket 17, a pushing cylinder 18 and an arc-shaped clamping sleeve 19. The disassembly and assembly bracket 17 is fixedly connected to the outer side of the conveying platform 1, the pushing cylinder 18 is threadedly connected to the surface of the disassembly and assembly bracket 17, and the middle part of the protruding end of the arc-shaped clamping sleeve 19 is fixedly connected to the outer side of the output end of the pushing cylinder 18.

[0042] The loading assembly 8 includes a material guide platform 22, a loading conveyor frame 23, a hydraulic cylinder 24, a flip base 25, a pneumatic finger 26, a flip shaft 27, a locking gear 28 and a rack 29. The outer side of the piston end of the hydraulic cylinder 24 is fixedly connected to the rack 29, the rack 29 is slidably connected to the top of the flip base 25, the pneumatic finger 26 is rotatably connected to the inner side of the flip shaft 27, the flip shaft 27 is fixedly connected to the top of the flip base 25, the flip base 25 is fixedly connected to the top of the material guide platform 22, the loading conveyor frame 23 is fixedly connected above the material guide platform 22, and the locking gear 28 is sleeved on the outer side of the flip shaft 27 and meshed with the inner tooth groove of the rack 29.

[0043] The disassembled bearing parts slide smoothly through the cleverly designed through slots 30 and are accurately placed in the circular material box 37 below. This layout not only ensures the safe storage of the parts, but also greatly facilitates the subsequent unloading operation. The pneumatic finger 26 starts quickly after receiving the signal, and the precision gear rack 29 mechanism inside it works together to slowly lift the pneumatic finger 26 and the bearing parts it holds in a smooth and stable manner. This process not only ensures the stability and safety of the parts during the transfer process, but also significantly improves the efficiency and accuracy of loading. As the pneumatic finger 26 accurately places the parts on the conveying station of the loading conveyor 23, the purpose of rapid loading is achieved.

[0044] A through slot 30 is also provided in the middle of the disassembly bracket 17 on the opposite side of the arc-shaped clamping sleeve 19 .

[0045] A pushing seat 31, a power cylinder 32, a driving motor 33 and a transmission gear 34 are also provided on the outer side of the limiting support 2. The pushing seat 31 is slidably connected to the outer side of the limiting support 2, the output end of the power cylinder 32 is fixedly connected to the one side surface of the pushing seat 31, the driving motor 33 is threadedly connected to the inner side of the pushing seat 31, and the transmission gear 34 is respectively sleeved on the outer side of the output end of the knocking tube 3 and the driving motor 33, and the outer teeth of the two sets of transmission gears 34 are meshed.

[0046] A linear slide rail 35 and a slide groove 36 with mutually matching sizes are also provided at the connection between the limiting support 2 and the sliding sleeve 16 .

[0047] Working principle: The bearing with disassembly and assembly can be placed on the conveying platform 1. As the material is conveyed to the clamping station, the rotating wrist 20 moves slowly according to the preset path and speed, driving the clamping arm body 21 to accurately approach the bearing to be operated. The hydraulically driven clamping arm body 21 clamps the bearing and accurately places the inner ring of the bearing on the outside of the knocking cylinder 3. At the same time, the heavy-duty oil cylinder 14 on the outside of the four-claw bracket 13 is started, and its output end pushes the thick rod 15, and the thick rod 15 pushes the sliding sleeve 16, and the sliding sleeve 16 is inside the fixed support. The sliding sleeve 16 is pushed outward horizontally along the outer side of the track of the linear slide rail 35, and the sliding sleeve 16 pushes the outer knocking cylinder 3. In this process, the outermost insertion pillar 9 extends into the inner ring of the bearing with the displacement. When the outermost curved hook block 10 extends out of the other side of the inner ring of the bearing, the inner electric telescopic rod 12 is started, and its output end pushes the inner ring abutment plate 11, and the inner ring abutment plate 11 drives the curved hook block 10 to move outward, and then the outer power cylinder 32 is started to push the push seat 31, and the push seat 31 drives the drive motor 33. The outer transmission gear 34 is close to the knocking cylinder 3. Since the two sets of transmission gears 34 are meshed, the knocking cylinder 3 can drive the insertion support 9 and the outermost curved hook block 10 to rotate under the gear transmission. The curved hook block 10 is firmly locked in the precise position between the inner ring of the bearing and the roller through the rotating knocking block, so as to achieve the purpose of full fit. Then, the electric telescopic rod 12 is started to continue to open the clamped inner ring of the bearing. At the same time, the reverse starting power cylinder 32 moves the transmission gear 34 on the side of the drive motor 33 away, and the knocking cylinder 3 Push the clamped bearing on the outside to approach the disassembly bracket 17, and then start the push cylinder 18 on the surface of the disassembly bracket 17 to push the two sets of arc-shaped clamping seats towards each other, so as to complete the clamping of the outer ring of the bearing, so that the outer ring of the bearing and the through groove 30 are mutually level. With the continued pressure of the heavy oil cylinder 14, the inner ring of the bearing can be quickly pulled out from the inner side of the bearing retainer. If it is necessary to collect the disassembled inner ring, the electric telescopic rod 12 can be reversed to cooperate with the heavy oil pressure to loosen the inner ring, and the inner ring falls into the circular material box 37 along the through groove 30 to complete the unloading. Other components can enter the clamping position of the pneumatic finger 26 along the guide table 22 under the conveyance of the conveying table 1, start the hydraulic cylinder 24, and the pneumatic finger 26 slowly lifts the clamped bearing component under the cooperation of the locking gear 28 and the rack 29 and completes a 180° rotation. Then release the starting finger, and the bearing component falls into the conveying position of the loading conveying rack 23 to complete the automatic loading.
