Description

Technical Field

[0001] This utility model relates to the technical field of bearing production equipment, and in particular to a flexible production equipment suitable for bearings of various specifications. Background Technology

[0002] In the bearing manufacturing industry, with the diversification of market demand, the same production line needs to frequently switch between processing bearings with different inner and outer diameters. This places higher demands on the flexibility and adaptability of production equipment. Stamping is one of the core processes in bearing production. During stamping, the bearing workpiece must be precisely fixed at the processing station to prevent quality problems such as dimensional deviations and surface damage caused by workpiece slippage. Therefore, designing a flexible production device that can adapt to multiple bearing specifications and has a stable clamping function is crucial for improving bearing production efficiency and ensuring product quality. It is also an important research direction for optimizing production lines in the industry. In current bearing production, the mechanical structures used for clamping workpieces mostly employ rigid chucks or fixed-size clamping fixtures. Their technical principle typically involves manually adjusting bolts or pneumatically driving a single-sized clamping plate to achieve a secure fit between the clamping plate and the outer circumference of the bearing. For example, some devices use symmetrically arranged fixed baffles, with the baffle spacing changed by manually rotating adjusting screws to accommodate different bearing sizes; other devices use a single-stroke cylinder to drive the clamping plate, with preset positioning blocks limiting the clamping plate's movement distance. These devices can only clamp bearings within a specific range of sizes, and during clamping, the clamping plate position must be manually adjusted by visual observation to ensure a proper fit with the bearing. However, existing clamping structures have significant limitations and cannot meet the demands of efficient production of bearings of various specifications. Specifically, existing clamping structures have poor compatibility. When switching to process bearings with different outer diameters, it is necessary to disassemble and replace the appropriate clamping plates or repeatedly adjust the positioning components manually. This is not only cumbersome and time-consuming, but also prone to insufficient fit between the clamping plates and the bearings due to adjustment errors. At the same time, some devices lack effective guiding mechanisms. During the movement of the clamping plates driven by the cylinder, the clamping plates are prone to displacement, resulting in a decrease in bearing positioning accuracy. This, in turn, causes workpiece slippage during stamping, affecting product dimensional accuracy and processing stability. Therefore, a flexible production device suitable for bearings of various specifications is proposed to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution: The elastic sleeve has a locking block fixedly connected inside, the side wall of the locking block is slidably connected inside the pressure head, and the side wall of the elastic sleeve is threadedly connected to a locking block.

[0009] As a further description of the above technical solution: The mounting sleeve has a rotating rod slidably connected inside. One end of the rotating rod is fixedly connected to a limiting plate, and the side wall of the limiting plate is slidably connected inside the locking block.

[0011] As a further description of the above technical solution: A limiting block is fixedly connected to the side wall of the rotating rod, and the side wall of the limiting block is slidably connected inside the mounting sleeve.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a flexible production device suitable for bearings of various specifications, including a frame 1. A conveyor belt 2 is rotatably connected inside the frame 1, used to transport bearing workpieces to be processed and those already processed. A support 3 is fixedly connected to the side wall of the frame 1, and an electric actuator 4 is fixedly connected to the top of the support 3. The electric actuator 4 is a DTZ300 model electric actuator, used to provide the power required for the pressing head 5. The pressing head 5 is located at the bottom of the electric actuator 4, and its function is to directly contact the bearing part to be processed. Combined with the power output of the electric actuator 4, precise pressing of the bearing is achieved. The stamping process is effective, and the mold steel material ensures that the press head 5 has good wear resistance and impact resistance, extending its service life. The side wall of the frame 1 is equipped with a fixing component, which is used to clamp and fix the bearing at the processing station. In conjunction with the stamping action of the press head 5, it achieves the effect of preventing the bearing from slipping and ensuring stamping accuracy. The side wall of the press head 5 is equipped with a disassembly and assembly component, which is used to realize the quick installation and disassembly of the press head 5. In accordance with the processing requirements of different specifications of bearings, it achieves the effect of adapting to multiple specifications of processing without changing the entire tooling, and only by changing the press head 5, thus improving the efficiency of specification switching. The fixing assembly includes a clamping plate 7 and a connecting plate 8. The side wall of the clamping plate 7 is fixedly connected to the side wall of the connecting plate 8. The clamping plate 7 is used to directly contact the outer circle of the bearing and clamps the bearing by moving synchronously with the connecting plate 8. The side wall of the connecting plate 8 is slidably connected inside the bracket 3, and a rack 9 is fixedly connected to the side wall of the connecting plate 8. A sliding block 10 is fixedly connected to the side wall of the connecting plate 8. The sliding block 10 is slidably connected to the inside of the frame 1. The sliding block 10 is used to guide the horizontal movement of the connecting plate 8. In conjunction with the sliding connection between the connecting plate 8 and the bracket 3, the guiding effect is achieved, and the deviation or jamming of the connecting plate 8 during movement is avoided. A cylinder 11 is fixedly connected to the bottom of the frame 1. The cylinder 11 is a standard cylinder of model SC63×200, which is used to provide clamping power for the fixing components, achieving the effect of precise control of clamping force and clamping stroke, and adapting to the clamping requirements of bearings with different outer diameters. A fixed block 12 is fixedly connected to the output end of cylinder 11. A rotating plate 13 is rotatably connected to the side wall of the fixed block 12. A toothed block 14 is rotatably connected to one side of the rotating plate 13. The side wall of the toothed block 14 is rotatably connected to the bottom of the frame 1. The toothed block 14 is used to convert its own rotational motion into the horizontal linear motion of the rack 9 by meshing with the rack 9. With the power output of cylinder 11 and the linkage of rotating plate 13, the connecting plate 8 and clamping plate 7 are driven to move, so as to achieve the effect of precisely adjusting the clamping and loosening state of clamping plate 7 and realize flexible clamping of bearings of different specifications. A controller 6 is fixedly connected to the side wall of the frame 1. The controller 6 is a PLCS7-200SMART programmable logic controller. The controller 6 is used to receive the detection signal of the infrared sensor 15 and send action commands to the electric push rod 4 and the cylinder 11, thereby achieving the effect of automated control of the overall operation process of the device and reducing manual intervention. An infrared sensor 15 is fixedly connected to the side wall of the bracket 3. The infrared sensor 15 is a diffuse reflection infrared sensor of model E3Z-LS63. The infrared sensor 15 is used to detect whether the bearing on the conveyor belt 2 has reached the processing position. With the signal processing of the controller 6, the effect of accurately triggering the conveyor belt 2 to stop and the cylinder 11 to start the clamping action is achieved, ensuring that the bearing can stay directly under the pressure head 5 every time. Reference Figures 4-5 The assembly and disassembly components include a mounting sleeve 16. The top of the mounting sleeve 16 is fixedly connected to the output end of the electric actuator 4. With the vertical movement of the electric actuator 4, the entire assembly and disassembly components and the pressure head 5 move synchronously, achieving the effect that the pressure head 5 accurately performs the stamping action with the electric actuator 4. The side wall of the pressure head 5 is slidably connected inside the mounting sleeve 16. The mounting sleeve 16 provides guidance for the installation and disassembly of the pressure head 5 through the sliding cooperation between the inner wall and the side wall of the pressure head 5, avoiding eccentricity during the installation of the pressure head 5. An elastic sleeve 17 is fixedly connected to the bottom of the mounting sleeve 16. The elastic sleeve 17 is made of 65Mn spring steel and has good elastic deformation capability and reset performance. The elastic sleeve 17 is used to wrap the side wall of the pressure head 5 and achieves clamping of pressure heads 5 of different specifications through its own deformation, thereby enhancing the installation stability of the pressure head 5. The side wall of the pressure head 5 is slidably connected inside the elastic sleeve 17. A locking block 18, made of tungsten steel, is fixedly connected inside the elastic sleeve 17. The locking block 18 is used to embed into the slot inside the pressure head 5. Together with the elastic sleeve 17 enveloping the pressure head 5, it achieves a preliminary anti-dislodgement positioning effect, preventing the pressure head 5 from falling out of the elastic sleeve 17 when not locked. The side wall of the locking block 18 is slidably connected inside the pressure head 5. Through the sliding engagement between the locking block 18 and the slot of the pressure head 5, the preliminary positioning of the pressure head 5 can be quickly completed, and it is also convenient for the pressure head 5 to easily disengage from the locking block 18 during disassembly. The elastic sleeve 17 has a locking block 19 threadedly connected to its side wall. The locking block 19 is made of 304 stainless steel and has threads on its inner wall that are compatible with the elastic sleeve 17. The locking block 19 is used to apply radial tightening force to the elastic sleeve 17 by rotating the threads. Combined with the elastic deformation of the elastic sleeve 17, it achieves the effect of tightly wrapping the side wall of the pressure head 5 with the elastic sleeve 17 and enhancing the clamping force, preventing the pressure head 5 from loosening or shifting during the stamping process. At the same time, the threaded connection structure of the locking block 19 facilitates quick manual operation and improves the efficiency of disassembling and assembling the pressure head 5. The mounting sleeve 16 has a sliding connection to a rotating rod 20. One end of the rotating rod 20 is fixedly connected to a limiting plate 21. The limiting plate 21 is used to insert into the limiting groove inside the locking block 19, and tightens in conjunction with the threads of the locking block 19. This prevents the threads of the locking block 19 from loosening due to stamping vibration, ensuring the long-term stable operation of the pressure head 5. The side wall of the limiting plate 21 is slidably connected inside the locking block 19. Through the sliding cooperation between the limiting plate 21 and the limiting groove of the locking block 19, the limiting state can be quickly switched. This facilitates the removal of the restriction on the locking block 19 when the pressure head 5 is disassembled. A fixing ring 22 is rotatably connected to the side wall of the rotating rod 20. A spring 23 is provided inside the mounting sleeve 16. The spring 23 is used to provide continuous elastic force. Together with the fixing ring 22 and the rotating rod 20, the limiting plate 21 is kept in a limiting state on the locking block 19, preventing the limiting plate 21 from accidentally disengaging from the locking block 19. One end of the spring 23 is fixedly connected to the inside of the mounting sleeve 16, and the other end of the spring 23 is fixedly connected to the side wall of the fixing ring 22. The side wall of the rotating rod 20 is fixedly connected to a limiting block 24. The limiting block 24 is used to restrict the rotation of the rotating rod 20 inside the mounting sleeve 16, thereby preventing the rotating rod 20 from falling off the mounting sleeve 16 due to excessive rotation. The side wall of the limiting block 24 is slidably connected inside the mounting sleeve 16 to ensure that the limiting plate 21 can be accurately inserted into or disengaged from the limiting groove of the locking block 19.

[0018] Working principle: When using this equipment, the bearing workpiece to be processed is first placed on the conveyor belt 2. The conveyor belt 2 rotates inside the box frame 1, and the bearing is uniformly transported to the processing area directly below the pressure head 5. When the bearing moves to the target position with the conveyor belt 2, the infrared sensor 15 fixed on the side wall of the bracket 3 detects the bearing signal and then sends a trigger command to the controller 6. The controller 6 immediately controls the conveyor belt 2 to stop rotating, ensuring that the bearing stops precisely at the processing position. Next, the controller 6 sends an action command to the cylinder 11. The output end of the cylinder 11 retracts, pulling the fixed block 12 to move. When the fixed block 12 moves, it drives the rotating plate 13 to rotate around the connection point. The other end of the rotating plate 13 simultaneously pushes the toothed block 14 to rotate around its own axis. During the rotation of the toothed block 14, its tooth surface meshes with the rack 9 fixed to the side wall of the connecting plate 8, driving the rack 9 and the connecting plate 8 to move in the horizontal direction. At the same time, the sliding block 10 fixed to the side wall of the connecting plate 8 slides inside the frame 1, providing guidance for the connecting plate 8 and preventing movement deviation. When the connecting plate 8 moves, it drives the clamping plate 7 fixed to it to move closer to the bearing until the side wall of the clamping plate 7 is in contact with the outer circle of the bearing. Since the stroke of the cylinder 11 can be adjusted by the controller 6, it can be adapted to bearings with different outer diameter specifications to achieve flexible clamping.

[0019] Then, the pressure head 5 to be installed is inserted into the mounting sleeve 16, ensuring that the side wall of the pressure head 5 is in contact with the inner wall of the elastic sleeve 17 fixed at the bottom of the mounting sleeve 16. At this time, the locking block 18 inside the elastic sleeve 17 slides into the corresponding slot of the pressure head 5, achieving initial anti-disengagement positioning. Next, the locking block 19 is rotated, and the locking block 19 moves along the thread of the elastic sleeve 17 towards the mounting sleeve 16. During this process, a radial tightening force is generated on the elastic sleeve 17, causing a slight deformation of the elastic sleeve 17, tightening it. The locking block 19 tightly encloses the outer circle of the pressure head 5 to ensure the coaxiality and clamping stability of the pressure head 5. When the locking block 19 rotates to the end of the thread, the rotating rod 20 is pulled to push the fixing ring 22 to move outward, so that the spring 23 is stretched and the limiting block 24 slides out from the inside of the mounting sleeve 16. Then the limiting plate 21 is slid into the corresponding limiting groove of the locking block 19, the spring 23 retracts, and the limiting block 24 slides into the inside of the mounting sleeve 16 again, so as to realize the mechanical limiting of the locking block 19 and prevent it from loosening due to stamping vibration. During disassembly, by manually pulling the end of the rotating rod 20 away from the locking block 19, the rotating rod 20 drives the fixed ring 22 to stretch the spring 23. At the same time, the limiting plate 21 disengages from the limiting groove of the locking block 19, and the limiting block 24 slides out from the inside of the mounting sleeve 16, releasing the limitation on the locking block 19. Then, the locking block 19 is rotated in the opposite direction, causing it to move outward along the thread of the elastic sleeve 17. After the elastic sleeve 17 loses its radial tightening force, it recovers its deformation, and the clamping state is released. The pressure head 5 is then pulled out from the inside of the mounting sleeve 16 and the elastic sleeve 17, completing the disassembly of the old pressure head 5. Then, the installation and locking steps of the pressure head 5 are repeated, and the new specification pressure head 5 is installed, which can realize the rapid switching of multi-specification bearing processing.
