Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology and relates to a raw material cutting device for processing bearing races. Background Technology

[0002] In the manufacturing process of bearing races, the tubular raw material first needs to be cut into individual ring-shaped blanks according to a predetermined width. The cutting of bearing race raw materials is mainly done using laser cutting. Laser cutting has advantages such as high cutting speed, small kerf width, narrow heat-affected zone, and high processing precision, which can effectively improve the cutting efficiency and quality of bearing race blanks.

[0003] When using laser cutting of tubular raw materials, the high-energy-density laser beam melts the metal material instantly, generating high-temperature molten material that sputters onto the inner wall of the raw material. After cooling, this molten material forms slag, requiring subsequent slag removal treatment and affecting the internal quality and subsequent performance of the workpiece.

[0004] To address the aforementioned problems, this invention proposes a raw material cutting device for machining bearing races. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a raw material cutting device for bearing race machining.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a raw material cutting device for machining bearing races, comprising: A frame, on which a raw material feeding mechanism and a laser cutter are mounted; The cutting part receiving cart includes a base plate, a guide column fixed on the base plate, a slider that moves up and down along the guide column, and a drive mechanism. The guide column has a through-cavity inside, and one end of the guide column is pre-inserted into the raw material before cutting. A cleaning component is provided at the end of the guide column. The driving mechanism includes a motor rotatably connected to the slider, a shaft mounted on the output shaft of the motor, and a transmission component passing through the inner cavity; the two ends of the transmission component are respectively connected to the cleaning component and the shaft. The motor rotates relative to the slider, causing the drive mechanism to switch between a first working state and a second working state. In the first working state, the motor drives the cleaning component to rotate through the transmission component to clean the outer wall of the guide column. In the second working state, the shaft winds and coils the transmission component, pulling the slider upward to lift the workpiece.

[0007] Furthermore, the cutting part receiving cart also includes an L-shaped seat fixed to the base plate, and the guide column is fixedly installed on the L-shaped seat. The guide column includes a vertical section and a horizontal section that bends and extends from the top of the vertical section; and the vertical section of the guide column is provided with a vertical groove for guiding the slider to rise and fall.

[0008] Furthermore, the cleaning component is a scraper, and a rotating plate is rotatably connected to the front end of the horizontal section of the guide column. The cleaning component is fixedly mounted on the rotating plate. One end of the transmission component extends to the front end of the horizontal section and is fixedly connected to the rotating plate, so as to drive the cleaning component to rotate and scrape off the slag along the outer wall of the guide column.

[0009] Furthermore, the slider is rotatably connected to a rotating frame, and the motor is fixedly connected to the rotating frame; the slider is fixedly connected to a connecting plate, and the rotating frame is elastically slidably connected to a plug rod, with a plug hole provided on the connecting plate; an inclined surface is provided on the lower side of the connecting plate; when the rotating frame is in a vertical state, the drive mechanism is in a first working state; the rotating frame drives the motor to rotate upward 90 degrees, and the plug rod is inserted into the plug hole, so that the drive mechanism is in a second working state.

[0010] Furthermore, a side groove is provided on the shaft, and one end of the transmission component is located in the side groove.

[0011] Furthermore, a rubber strip is provided on the outer side of the guide column.

[0012] Furthermore, it also includes a rotating platform, which is rotatably mounted on one side of the frame, and the rotating platform has a mating interface that cooperates with the base plate.

[0013] Furthermore, a vertical rod is fixedly installed on the rotating platform, and a through groove that mates with the vertical rod is provided on the L-shaped seat. When the base plate moves away from the rotating platform, the vertical rod pushes the motor to rotate, so that the shaft is in a horizontal state.

[0014] Furthermore, a locking assembly for locking the cut-off part receiving cart is installed on the rotating platform. The locking assembly includes a fixed plate fixed to the rotating platform, a U-shaped rod slidably connected to the fixed plate, a locking block and a limiting rod fixedly connected to the U-shaped rod, a locking groove that cooperates with the locking block on the L-shaped seat, and a sliding through hole that cooperates with the limiting rod on the rotating frame.

[0015] Furthermore, an L-shaped rod is mounted on the rotating platform, and a magnet is mounted at the end of the L-shaped rod. The magnet is used to attract the insertion rod, causing the insertion rod to dislodge from the insertion hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The horizontal section of the guide column is pre-inserted into the raw material before cutting. The high-temperature molten material generated by laser cutting falls onto the outer wall of the horizontal section of the guide column, avoiding falling onto the inner wall of the raw material and solving the problem of slag residue. No additional slag cleaning process is required before proceeding directly to subsequent turning machining, effectively ensuring the inner wall quality of the bearing race and the accuracy of subsequent machining.

[0017] 2. After cutting, the bearing races slide along the horizontal section of the guide column to the vertical section and automatically stack on the slider, achieving orderly stacking of the blanks. The rubber strips decelerate the falling bearing races step by step, avoiding collisions and damage between blanks. The orderly stacking of blanks provides convenient conditions for subsequent material handling and turning.

[0018] 3. During subsequent material handling, the slider rises layer by layer as the top workpiece is removed, ensuring that the topmost workpiece remains at the top of the vertical section of the guide column. Workers can retrieve workpieces from the same height while standing, eliminating the need for frequent bending or squatting, effectively reducing physical exertion and shortening the time required to retrieve a single workpiece.

[0019] 4. Through the cooperation of the rotary table and multiple cutting part receiving trolleys, the fully loaded trolley can be switched to an empty trolley at any time, eliminating the need for long-term downtime during cutting operations. The fully loaded trolley can be flexibly moved to subsequent processing equipment, realizing parallel operations of cutting, stacking, transportation, and material handling, thereby improving equipment utilization and production efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-20 As shown, the technical solution adopted by the present invention is as follows: A raw material cutting device for processing bearing races includes a frame 1, a raw material feeding mechanism, a laser cutter 7, and a cutting part receiving cart.

[0024] like Figure 1 As shown, the raw material feeding mechanism includes an electrically controlled rotating ring 2, a cross plate 4, and electric rollers 5 mounted on the frame 1. Two electrically controlled rotating rings 2 are provided, both fixedly mounted on the frame 1. Two cross plates 4 are symmetrically mounted between the two electrically controlled rotating rings 2. Multiple electric rollers 5 are mounted on each cross plate 4, and cylinders 3 are connected to both ends of each cross plate 4, with the cylinders 3 mounted on the corresponding electrically controlled rotating ring 2. When raw material 45 is placed between the two cross plates 4, the cylinders 3 are activated, and the raw material 45 is clamped between the two cross plates 4. The electric rollers 5 drive the raw material 45 to move axially along the electrically controlled rotating ring 2.

[0025] A three-jaw chuck 6 is mounted on the frame 1. The three-jaw chuck 6 is used to clamp and fix the raw material 45.

[0026] The laser cutter 7 is mounted on the frame 1 and is used to cut the raw material 45.

[0027] Driven by the electric roller 5, the raw material 45 is fed in the cutting direction. After feeding, the three-jaw chuck 6 clamps and fixes the raw material 45. Then, the electrically controlled rotating ring 2 drives the raw material 45 to rotate, and the laser cutter 7 performs the cutting operation.

[0028] The cutting part receiving carriage includes a base plate 20, a slider 31, a guide column 27, and a drive mechanism.

[0029] The bottom of the base plate 20 is fixedly connected with multiple casters 21. The casters 21 are preferably casters with a self-locking function, which facilitates the positioning and fixing of the cutting part receiving cart after it has been moved into place. A push handle 22 is fixedly connected to the base plate 20, which facilitates the movement of the cutting part receiving cart by the operator.

[0030] An L-shaped seat 23 is fixedly connected to the top of the base plate 20. A slot 25 is provided on both sides of the L-shaped seat 23, and a limiting surface 26 is also provided on both sides of the L-shaped seat 23.

[0031] The guide column 27 is fixed to the top of the L-shaped seat 23.

[0032] The guide column 27 includes a vertical section and a horizontal section extending from the top of the vertical section, meaning the top of the guide column 27 has a horizontally extending receiving section. The guide column 27 has a through-cavity that extends through both the vertical and horizontal sections along its extension direction. The vertical section of the guide column 27 has two vertical grooves 29 and two vertical clearance grooves 30, all extending along the height of the vertical section.

[0033] During cutting, the horizontal section of the guide column 27 is inserted into the raw material 45. When the cut workpiece is pushed, it slides down along the horizontal end of the guide column 27 to the vertical section, and then slides down the vertical section onto the slider 31. The molten slag generated during the cutting process falls onto the outer wall of the horizontal section of the guide column 27, preventing molten slag from falling onto the inner wall of the workpiece. The horizontal and vertical sections of the guide column 27 are connected by an arc transition section, allowing the bearing race to smoothly rotate through the arc transition section and then slide down the vertical section.

[0034] A rotating plate 43 is rotatably mounted on the front end of the horizontal section of the guide column 27, and a cleaning component 44 is provided on the outer wall of the horizontal section of the guide column 27. The rotating plate 43 and the cleaning component 44 are fixedly connected. The rotating plate 43 drives the cleaning component 44 to rotate, and the cleaning component 44 cleans the slag on the outer wall of the guide column 27. In this embodiment, the cleaning component 44 is a scraper. The cutting edge of the scraper is in contact with the outer wall of the horizontal section of the guide column 27 and is used to scrape off the cooling slag on the outer wall of the guide column 27 during rotation.

[0035] Each vertical groove 29 has a slider 31 slidably disposed therein. The slider 31 is L-shaped, and one end of the slider 31 is slidably disposed within the vertical groove 29.

[0036] Each slider 31 is fixedly connected to a connecting plate 32, which is located outside the vertical section of the guide column 27.

[0037] Each slider 31 is rotatably connected to a rotating frame 35, the axis of rotation of which extends horizontally. The axes of rotation of the two rotating frames 35 are collinear. Figure 15 As shown, a sliding through hole 36 is provided on the rotating frame 35, and an insert rod 37 is slidably disposed in the sliding through hole 36. The insert rod 37 can slide along its own axis within the sliding through hole 36. The two ends of the tension spring 38 are fixedly connected to the rotating frame 35 and the insert rod 37 respectively, and the tension spring 38 always applies an elastic force to the insert rod 37 toward the inside of the rotating frame 35.

[0038] like Figure 14 As shown, the connecting plate 32 has a socket 34 on its side. The socket 34 is used to mate with the plug rod 37. The bottom of the connecting plate 32 has a bevel 33.

[0039] When the rotating frame 35 rotates to a horizontal position, the insertion rod 37 retracts into the sliding through hole 36 under the action of the inclined plane 33. When the rotating frame 35 is in a horizontal position, the insertion rod 37 is aligned with the insertion hole 34, and the insertion rod 37 is inserted into the insertion hole 34 under the action of the tension spring 38. This keeps the rotating frame 35 in a horizontal position.

[0040] The drive mechanism includes a motor 39, a shaft 40, and a transmission component 42.

[0041] like Figure 14 As shown, motor 39 is fixedly connected to two rotating frames 35, and motor 39 can rotate synchronously with the rotating frames 35. A shaft 40 is fixedly connected to the motor shaft of motor 39, and a side groove 41 is formed at the top end of shaft 40. Figure 7 , Figure 8 As shown, the bottom end of the transmission component 42 is fixedly connected to the side wall of the side groove 41, and the top end of the transmission component 42 extends through the inner cavity of the guide column 27 to the front end of the horizontal section of the guide column 27 and is fixedly connected to the rotating plate 43.

[0042] In this embodiment, the transmission component 42 is preferably a steel wire rope or a stainless steel multi-strand stranded rope with a certain outer diameter. The steel wire rope has the characteristics of high tensile strength and excellent bending fatigue performance, enabling it to withstand large tensile forces without breaking under the winding action of the shaft 40, while also transmitting torque under tension. The steel wire rope or stainless steel multi-strand stranded rope is made by twisting multiple steel wires around a core. The core of the steel wire rope is preferably a steel core to improve its compressive and torsional resistance. The surface of the steel wire rope can be coated with grease to reduce friction with the inner wall of the guide column 27.

[0043] In other embodiments, the transmission element 42 may also be a roller chain, which is composed of multiple chain links hinged together in sequence.

[0044] In another embodiment, the transmission element 42 is a flexible metal shaft with an ultra-flexible structure.

[0045] The drive mechanism has two working states, such as Figure 10 , Figure 12 , Figure 14 As shown, the drive mechanism is in its first working state, the rotating frame 35 is in a vertical state, and the shaft 40 is in a vertical state. The motor 39 starts, driving the shaft 40 to rotate. The shaft 40 drives the rotating plate 43 to rotate through the tensioned transmission component 42, which in turn drives the cleaning component 44 to rotate, so as to clean the horizontal section of the guide column 27.

[0046] A collection trough 8 is also fixedly connected to the frame 1. The collection trough 8 is located below the end of the guide column 27 and is used to collect the slag that has been cleaned up.

[0047] like Figure 16 , Figure 17 , Figure 20As shown, the drive mechanism is in its second working state, with the insertion rod 37 inserted into the insertion hole 34, and the rotating frame 35 and the shaft 40 in a horizontal state. The motor 39 drives the shaft 40 to rotate, causing the transmission component 42 to gradually wrap around the shaft 40, thus shortening the transmission component 42. Consequently, the motor 39, the shaft 40, and the slider 31 gradually move upward along the guide column 27, and drive the workpiece on the guide column 27, i.e., the cut bearing seat, to move upward.

[0048] The vertical clearance groove 30 provides vertical movement space for the shaft 40, and the vertical slide 29 provides a space for the transmission component 42 that is wound around the outside of the shaft 40.

[0049] Multiple rubber strips 28 are fixedly connected to the outer side of the vertical section of the guide column 27, and the rubber strips 28 are spaced apart along the height direction of the vertical section. The diameter of the circle formed by the multiple rubber strips 28 on the same horizontal plane is larger than the inner diameter of the raw material 45, and the rubber strips 28 are in a horizontal state when not subjected to external force. The rubber strips 28 are used to decelerate and buffer the bearing races sliding down the vertical section of the guide column 27, preventing the bearing races from directly and rapidly impacting the slider 31 and causing collision damage.

[0050] A rotating platform 10 is provided on one side of the frame 1. The rotating platform 10 is rotatably connected to an electrically controlled turntable 9, which can drive the rotating platform 10 to rotate around a vertical axis. The electrically controlled turntable 9 is fixedly installed on the frame 1 or on the ground.

[0051] The rotating platform 10 has at least one interface 11, the shape and size of which are adapted to the shape and size of the base plate 20, and the base plate 20 can be inserted into the interface 11. A vertical rod 12 is fixedly connected to the rotating platform 10. A through slot 24 is provided on the L-shaped seat 23, the shape and size of which are adapted to the shape and size of the through slot 24, and the top surface of the vertical rod 12 is arc-shaped. The vertical rod 12 can pass through the through slot 24.

[0052] A locking assembly is provided on the rotating table 10. The locking assembly includes a fixed plate 13, a U-shaped rod 15, a locking block 16, and a limiting rod 17.

[0053] Both sides of the interface 11 are provided with fixing plates 13, which are fixedly connected to the rotating table 10. Each fixing plate 13 is fixedly connected with an electric push rod 14, and the telescopic end of the electric push rod 14 is fixedly connected with a U-shaped rod 15, which is slidably connected to the fixing plate 13. A locking block 16 and a limiting rod 17 are fixedly connected to the U-shaped rod 15. The shape and size of the locking block 16 are adapted to the shape and size of the locking groove 25, and the shape and size of the limiting rod 17 are adapted to the shape and size of the sliding through hole 36.

[0054] After the cutting part receiving cart is aligned with the rotating table 10, the electric push rod 14 is shortened. The electric push rod 14 drives the U-shaped rod 15 to move closer to the L-shaped seat 23. The U-shaped rod 15 drives the locking block 16 and the limiting rod 17 to move synchronously. The locking block 16 is inserted into the slot 25 on the L-shaped seat 23. Through the limiting engagement between the locking block 16 and the slot 25, the base plate 20 is locked onto the rotating table 10. At the same time, the limiting rod 17 is inserted into the sliding through hole 36 on the connecting plate 32. Through the limiting engagement between the limiting rod 17 and the sliding through hole 36, the slider 31 is locked, preventing the slider 31, connecting plate 32, rotating frame 35, and motor 39 from moving upward along the vertical slide groove 29, and preventing the motor 39 from rotating relative to the slider 31 via the rotating frame 35. In this way, the slider 31, connecting plate 32, rotating frame 35, motor 39 are locked together with the L-shaped seat 23 and the base plate 20 as a whole.

[0055] When it is necessary to remove the cut-off part receiving cart from the rotary table 10, the electric push rod 14 is extended. The electric push rod 14 drives the U-shaped rod 15 to move away from the L-shaped seat 23. The U-shaped rod 15 drives the locking block 16 and the limiting rod 17 to move synchronously. The locking block 16 moves out of the slot 25, releasing the lock between the base plate 20 and the rotary table 10. The limiting rod 17 moves out of the sliding through hole 36, releasing the lock on the slider 31.

[0056] In this embodiment, two interfaces 11 are provided, and the two interfaces 11 are distributed at intervals along the circumference of the rotating table 10.

[0057] Both sides of the interface 11 are provided with L-shaped rods 18, which are fixedly connected to the rotating table 10. Magnets 19 are fixedly connected to the ends of the L-shaped rods 18. The distance between the two magnets 19 is adapted to the distance between the two rotating frames 35. The magnets 19 are used to attract the insertion rod 37 when the cutting part receiving cart docks with the rotating table 10, so that the insertion rod 37 is dislodged from the insertion hole 34.

[0058] When the magnet 19 is facing the outer end face of the insertion rod 37, the attraction of the magnet 19 to the insertion rod 37 is greater than the elastic force of the tension spring 38, so as to overcome the tension of the tension spring 38 and pull the insertion rod 37 out of the insertion hole 34.

[0059] Working principle: Initial state and raw material feed: like Figures 1 to 14 As shown, in the initial state, the cutting part receiving cart and the rotating table 10 are in a docked and locked state. At this time, the base plate 20 is located in the interface 11, the vertical rod 12 is located on one side of the through groove 24, the locking block 16 is located in the locking groove 25, and the limiting rod 17 is located in the sliding through hole 36. The front end of the horizontal section of one of the guide columns 27 is collinear with the three-jaw chuck 6. The drive mechanism is in the first working state.

[0060] The operator first places the raw material 45 to be cut onto the multiple electric rollers 5 located at the bottom. Then, the cylinder 3 on the horizontal plate 4 at the bottom is adjusted to extend or retract, so that the axis of the raw material 45 is collinear with the axis of the three-jaw chuck 6. Next, the cylinder 3 on the horizontal plate 4 at the top is extended, causing the multiple electric rollers 5 on the two horizontal plates 4 to clamp the raw material 45. The multiple electric rollers 5 are activated, moving the raw material 45 towards the guide column 27. After the front end of the horizontal section of the guide column 27 has inserted into the raw material 45 to the required distance, the multiple electric rollers 5 are deactivated. At this point, the horizontal section of the guide column 27 is inserted into the raw material 45, and the rotating plate 43 and the cleaning component 44 are located inside the raw material 45. Finally, the three-jaw chuck 6 is controlled to clamp and fix the raw material 45.

[0061] Laser cutting: The laser cutter 7 is activated to cut the raw material 45, and the electrically controlled rotating ring 2 and the three-jaw chuck 6 rotate synchronously, driving the raw material 45 to rotate, thus completing the cutting operation of the raw material 45. During the cutting process, the high temperature of the laser melts the metal instantly. The resulting molten material drips down under the influence of gravity and falls onto the outer side of the horizontal section of the guide column 27, rather than dripping onto the inner wall of the raw material 45, thus avoiding the problem of slag buildup on the inner wall. The cut ring is the bearing seat ring.

[0062] Continuous cutting and automatic stacking: After each bearing race is cut, the laser cutter 7 is temporarily shut down, and the three-jaw chuck 6 and the electrically controlled rotary ring 2 are paused. Then, the three-jaw chuck 6 is released from its holding position on the material 45, and the electric roller 5 is rotated to move the material 45 forward a certain distance (i.e., feed one cutting length). The three-jaw chuck 6 is then controlled to clamp and fix the material 45. The laser cutter 7 is then restarted to cut again, and the electrically controlled rotary ring 2 and the three-jaw chuck 6 are activated to drive the material 45 to rotate synchronously for the next bearing race segment cutting operation.

[0063] During the leftward feeding of the raw material 45, the end of the raw material 45 pushes the cut bearing race located on the horizontal section of the guide column 27 to move along the horizontal section of the guide column 27, causing the cut bearing race to move to the vertical section of the guide column 27. Then, under its own gravity, the bearing race moves downward along the vertical section of the guide column 27. During this downward movement, the bearing race contacts multiple rubber strips 28, which decelerate the downward movement of the bearing race, causing it to fall onto the top surface of the two sliders 31 at a relatively slow speed. The falling bearing races then rest on the bearing race located below them, thus achieving automatic stacking of the bearing races.

[0064] As another implementation, the horizontal section at the top of the guide column 27 can be set to have a certain tilt angle, for example, tilted 2 to 3 degrees from the horizontal direction, so that the cut bearing race will automatically slide along the tilted section to the vertical section of the guide column 27.

[0065] Slag removal: After a period of cutting, a certain amount of cooled molten material will accumulate on the outer side of the horizontal section of the guide column 27. When the slag accumulates to a certain extent, it needs to be cleaned to prevent the slag from piling up indefinitely and causing the front end of the horizontal section of the guide column 27 to be unable to be inserted into the raw material 45.

[0066] During cleaning, first turn off the laser cutter 7, and stop the rotation of the three-jaw chuck 6 and the electrically controlled rotating ring 2. Then, control the three-jaw chuck 6 to release its fixing effect on the raw material 45, and control the electric roller 5 to rotate so that the raw material 45 moves backward and away from the guide column 27. After the front end of the horizontal section of the guide column 27 exits from the inside of the raw material 45, turn off the electric roller 5 to stop the movement of the raw material 45.

[0067] Then, motor 39 is started, driving shaft 40 to rotate. Shaft 40 drives tensioned transmission component 42 to rotate, transmission component 42 drives rotating plate 43 to rotate, and rotating plate 43 drives cleaning component 44 to rotate. Cleaning component 44 rotates and scrapes along the outer wall of the horizontal section of guide column 27, cleaning the slag adhering to the outside of guide column 27. The cleaned slag falls into collection tank 8 under gravity. After cleaning, motor 39 is turned off, and then the electrically controlled rotating ring 2, three-jaw chuck 6, electric roller 5, and laser cutter 7 continue to cut the raw material 45.

[0068] Material filling is full, so the material is rotated: When the bearing races are fully stacked on the outside of the guide column 27, the cutting operation is stopped. Then, the three-jaw chuck 6 is controlled to release its fixing effect on the raw material 45, and the electric roller 5 is controlled to rotate, causing the raw material 45 to move backward and away from the guide column 27. After the front end of the horizontal section of the guide column 27 exits from the inside of the raw material 45, the electric roller 5 is turned off to stop the movement of the raw material 45.

[0069] Then, the electrically controlled turntable 9 drives the rotating table 10 to rotate. Figure 1 The rotary table 10 rotates 90 degrees counterclockwise, causing the two base plates 20 to rotate synchronously. The two base plates 20 move on the ground via multiple casters 21. After the rotary table 10 rotates the two base plates 20 90 degrees counterclockwise, the electrically controlled rotary table 9 is turned off. At this time, the front end of the horizontal section of the new guide column 27 is collinear with the axis of the three-jaw chuck 6, and then the cutting operation of the raw material 45 can continue. The bearing races are then stacked on the outside of the new guide column 27.

[0070] Cutting part receiving cart removal and status switching: Then, the two electric push rods 14 corresponding to the positions of the guide column 27 that are filled with bearing races are extended. The electric push rods 14 drive the U-shaped rod 15, the locking block 16, and the limiting rod 17 to move, so that the locking block 16 moves out of the locking groove 25 and the limiting rod 17 moves out of the sliding through hole 36.

[0071] Then, the staff pulls the push handle 22, causing the base plate 20 to move away from the turntable 10 via the casters 21, thus removing the base plate 20 from the interface 11. During the outward movement of the base plate 20, the vertical rod 12 passes through the through slot 24 and drives the motor 39 to rotate clockwise. Figure 20 (clockwise direction). The motor 39 rotates clockwise relative to the slider 31 via the rotating frame 35. During this process, due to the large number of bearing races stacked above the two sliders 31, the sliders 31 press against the top surface of the L-shaped seat 23 under the weight of the large number of bearing races, and cannot move upward along the vertical groove 29. Therefore, during the clockwise rotation of the motor 39 relative to the sliders 31 via the rotating frame 35, the sliders 31 and the connecting plate 32 will not move upward.

[0072] Due to the height setting of the vertical rod 12, the motor 39 can rotate 90 degrees clockwise. During this rotation, the rotating frame 35 will drive the insertion rod 37 to rotate synchronously. When the insertion rod 37 passes the inclined plane 33, the insertion rod 37 is pressed into the sliding through hole 36. After the motor 39 rotates 90 degrees, the insertion rod 37 is directly opposite the insertion hole 34, and the insertion rod 37 is inserted into the insertion hole 34 under the elastic force of the tension spring 38. Through the limiting effect of the insertion rod 37 and the insertion hole 34, the motor 39 and the rotating frame 35 are fixedly connected to the connecting plate 32 and the slider 31. After the vertical rod 12 is moved away from the outside of the motor 39, the motor 39 will also remain horizontal under the limiting effect of the insertion rod 37 and the insertion hole 34. Figure 16 As shown. At this time, the shaft 40 is located in the vertical relief groove 30, the transmission component 42 and the two vertical sliding grooves 29 are in the same vertical plane, and the transmission component 42 is located in the middle position of the two vertical relief grooves 30.

[0073] At this point, the drive mechanism switches to the second working state. The operator can then use the pusher 22 to move the guide column 27, which is filled with bearing races, to the subsequent processing machine for further processing.

[0074] Subsequent material extraction and layer-by-layer lifting: In subsequent turning operations, the operator sequentially removes bearing races from the guide column 27 for machining. Each time the operator removes a bearing race from the top of the vertical section of the guide column 27, the motor 39 automatically starts (controllable via a manual button or sensor). The motor 39 drives the shaft 40 to rotate, and the shaft 40 winds and coils around the transmission component 42. Since the top of the transmission component 42 is fixed to the rotating plate 43, as the shaft 40 winds around the transmission component 42, the transmission component 42 pulls the motor 39, rotating frame 35, connecting plate 32, slider 31, and shaft 40 upwards. The two sliders 31 simultaneously drag multiple bearing races located above them upwards. After moving upwards by the thickness of one bearing race, the motor 39 is turned off.

[0075] Subsequently, when the worker removes another bearing race, the motor 39 will start again, thus ensuring that the topmost bearing race among the multiple bearing races on the outer side of the guide column 27 is always positioned at the top of the vertical section of the guide column 27. This facilitates the worker's retrieval without requiring frequent bending or even squatting to retrieve the bearing races located at the bottom of the guide column 27, until all bearing races have been removed.

[0076] During the winding process of the shaft 40 and the transmission component 42, the diameter of the transmission component 42 wound around the outside of the shaft 40 gradually increases. The two vertical grooves 29 can accommodate the transmission component 42 with its continuously increasing diameter. The spacing between the two L-shaped sliders 31 also helps to avoid the winding transmission component 42.

[0077] Since the width of the vertical clearance groove 30 is matched with the diameter of the shaft 40, the shaft 40 is located in the two vertical clearance grooves 30, and the transmission component 42 and the two vertical slide grooves 29 are in the same vertical plane. The transmission component 42 is located in the middle of the two vertical clearance grooves 30. Therefore, during the process of the shaft 40 winding the transmission component 42, the transmission component 42 wound on the shaft 40 will be located in the vertical slide groove 29. There is no need to worry that the transmission component 42 wound on the outside of the shaft 40 will slip off the end of the shaft 40 and cause the winding failure.

[0078] Empty cut-off part receiving cart reset: After all the bearing races on the outer side of the guide column 27 have been removed, the control motor 39 reverses, causing the shaft 40 to unwind the transmission component 42, so that the motor 39, rotating frame 35, connecting plate 32, and slider 31 move downwards along the vertical slide groove 29 until the slider 31 falls onto the L-shaped seat 23. At this time, if Figures 16 to 19 As shown.

[0079] Then, the operator can push the empty guide column 27 to the interface 11 of the rotating table 10 using the pusher 22, and then move the base plate 20 into the interface 11. During the movement, the vertical rod 12 first passes through the through slot 24. After the base plate 20 is inserted into the interface 11, the sliding through holes 36 on the two rotating frames 35 pass through the two magnets 19. When the sliding through holes 36 pass through the magnets 19, the magnets 19 generate an attractive force on the insertion rod 37, causing the insertion rod 37 to be pulled out from the insertion hole 34, and the tension spring 38 is stretched. Then, the motor 39 and the rotating frame 35 rotate counterclockwise relative to the connecting plate 32 under their own gravity. After the sliding through holes 36 and the magnets 19 are misaligned, the insertion rod 37 pops out under the elastic force of the tension spring 38. After the motor 39 rotates 90 degrees, the rotating frame 35 abuts against the limiting surface 26 and can no longer rotate counterclockwise. The motor 39 and the rotating frame 35 remain in a vertical state.

[0080] A rubber buffer pad is fixedly connected to the limiting surface 26. When the rotating frame 35 rotates to a vertical position under its own weight, the rotating frame 35 comes into elastic contact with the rubber buffer pad, which avoids the rotating frame 35 from rigidly colliding with the limiting surface 26 and causing noise or damage.

[0081] After the base plate 20 and the interface 11 are inserted into place, the two electric push rods 14 are activated to shorten, so that the locking block 16 and the limiting rod 17 are respectively inserted into the locking groove 25 and the sliding through hole 36. The drive mechanism returns to the first working state, preparing for the subsequent stacking of the bearing race.

[0082] Multiple cutting part receiving carts are used in a cyclical manner: In actual production, multiple cutting part receiving carts can be set up. Each time a cutting part receiving cart fully loaded with bearing races is removed from the rotary table 10, another empty cutting part receiving cart can be directly connected and installed to the rotary table 10. This ensures that there are always two cutting part receiving carts on the rotary table 10, one in receiving mode and the other in standby receiving mode. By rotating the rotary table 10 clockwise and counterclockwise, the two cutting part receiving carts are positioned sequentially in receiving positions, ensuring continuous receiving. Multiple cutting part receiving carts fully loaded with bearing races can be pushed to the vicinity of multiple machine tools for workers to pick up and process sequentially.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
