Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically to a multi-station machining equipment for turning shaft parts. Background Technology

[0002] Shaft parts are crucial components widely used in mechanical transmission systems, and their machining quality directly affects the performance and lifespan of the entire machine. Industries such as automotive manufacturing, construction machinery, and aerospace typically require efficient and precise turning of numerous shaft parts of varying specifications. To meet the demands of multi-station continuous machining, multi-station machining equipment is now widely used. This equipment utilizes multiple automated robotic arms and clamping mechanisms to achieve rapid clamping, precise positioning, and automated machining of parts. Such equipment significantly improves production efficiency, reduces manual labor intensity, and adapts to the automation and mass production trends of modern industrial production.

[0003] However, existing multi-station machining equipment for shaft parts generally suffers from complex structures, cumbersome operation, and high maintenance costs. Clamping mechanisms often rely on hydraulic or pneumatic drives, resulting in large devices with high energy consumption. Furthermore, the inconvenience of adjusting clamping components affects changeover efficiency. The gear transmission components lack reliable automatic lubrication systems, leading to severe gear wear after prolonged operation and reducing equipment lifespan. In addition, the clamping process easily damages the part surface, and the difficulty in replacing protective gaskets further increases maintenance complexity and machining scrap rates. These shortcomings limit the effectiveness of existing equipment in achieving efficient and stable production processes.

[0004] Therefore, this invention proposes a multi-station machining equipment for turning shaft parts to overcome the shortcomings of the prior art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-station machining equipment for turning shaft parts, which solves the problems of complex clamping mechanism structure, difficult adjustment, lack of automatic lubrication and easy wear of gear transmission, easy damage to the surface of parts during clamping, and inconvenience in replacing protective pads.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-station machining equipment for turning shaft parts, including a worktable, multiple automatic machining robotic arms installed on the top of the worktable, a motor installed inside the worktable, the output end of the motor passing through the top of the worktable and fixedly connected to a main gear, multiple fixing mechanisms provided on the top of the worktable, a lubrication mechanism provided inside the worktable, and a cabinet door installed on the outside of the worktable.

[0007] Preferably, the fixing mechanism includes a mounting plate, the bottom of which is fixedly connected to the top of the workbench via a fixing column. The top of the mounting plate has multiple limiting grooves. A connecting column is rotatably connected to the center of the mounting plate. A secondary gear is fixedly connected to the bottom of the connecting column. A turntable is fixedly connected to the top of the connecting column. A connecting rod is slidably connected inside the limiting grooves. A clamping plate is fixedly connected to the end of the connecting rod away from the connecting column. A protective mechanism is provided on one side of the clamping plate. A limiting column is fixedly connected to the end of the connecting rod away from the clamping plate. The top of the turntable has multiple sliding grooves.

[0008] Preferably, the lubrication mechanism includes an oil reservoir and a sleeve. The sleeve is fixedly connected to the inside of the workbench via a support plate. The oil reservoir is installed inside the workbench. A spring is provided inside the sleeve. A piston is slidably connected inside the sleeve. A push rod is fixedly connected to the side of the piston away from the spring. A disc is fixedly connected to the end of the push rod away from the piston. A cam is fixedly connected to the output end of the motor. The sleeve and the oil reservoir are fixedly connected via a connecting pipe. An oil outlet pipe is fixedly connected to the outside of the sleeve.

[0009] Preferably, the protective mechanism includes a rubber pad, a plurality of circular pillars are fixedly connected to the side of the rubber pad near the clamping plate, a rubber ring is fixedly connected to the outside of the circular pillars, and a circular hole corresponding to the circular pillar is opened on the side of the clamping plate near the rubber pad, and a groove is opened inside the circular hole.

[0010] Preferably, the main gear meshes with the secondary gear, and the limiting post is slidably connected inside the groove.

[0011] Preferably, a limiting plate is fixedly connected to the top of the limiting post, and the bottom of the limiting plate abuts against the top of the turntable.

[0012] Preferably, a one-way valve is installed inside the oil outlet pipe, and an electromagnetic one-way valve is installed inside the connecting pipe.

[0013] Preferably, one end of the spring is fixedly connected to the piston on the side away from the push rod, the other end of the spring abuts against the inner wall of the sleeve, and the end of the oil outlet pipe away from the sleeve is located above the edge of the main gear.

[0014] Preferably, the surface of the disk abuts against the cam, and the push rod is slidably connected inside the sleeve. Preferably, the circular cylinder is slidably connected inside the circular hole, and the rubber ring is engaged inside the groove.

[0015] This invention provides a multi-station machining equipment for turning shaft-type parts. It has the following beneficial effects: 1. This invention utilizes a fixed mechanism design where a motor drives the main gear to rotate, which in turn drives the secondary gear to rotate synchronously, achieving continuous rotation of the turntable. This allows the limiting post to slide within the groove, thereby causing the connecting rod and clamping plate to open and close within the limiting groove. By controlling the forward and reverse directions of the motor, the opening and closing of the clamping plate can be precisely controlled, quickly completing the clamping of shaft-like parts. Compared to existing technologies that rely on complex pneumatic or hydraulic control for clamping, this invention reduces the complexity of the system structure and the failure rate, solving the problems of cumbersome structure and difficult clamping adjustment in existing equipment.

[0016] 2. In this invention, the lubrication mechanism uses a motor to drive a cam to rotate, which, combined with the spring force, causes the piston to reciprocate within the sleeve. Simultaneously, by controlling the opening and closing of the electromagnetic check valve at set times, precise control of the lubricating oil's intake and discharge processes is achieved, ensuring timely supply of lubricating oil to the meshing parts of the main and auxiliary gears. Compared to traditional devices requiring frequent manual lubrication, this significantly reduces the frequency of manual maintenance and effectively solves the problem of severe gear wear due to untimely lubrication in existing equipment, resulting in a marked improvement in service life.

[0017] 3. This invention, by installing a rubber pad on the clamping plate and designing a circular cylinder that fits into the groove on the clamping plate to form an interference fit, not only effectively prevents surface damage to shaft parts during clamping but also makes the installation and replacement of the rubber pad more convenient and quick. Compared to traditional clamps that can only fix the buffer pad with screws or adhesive, this structure significantly reduces maintenance costs and avoids the problem of disassembling a large number of parts when replacing the buffer pad, thus improving the practicality and convenience of the equipment.

[0023] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 7 The fixing mechanism includes a mounting plate 16. The bottom of the mounting plate 16 is fixedly connected to the top of the workbench 1 via a fixing column 33. The top of the mounting plate 16 has multiple limiting grooves 32.

[0024] Specifically, the fixing mechanism includes a mounting plate 16, which serves as the mounting base for the clamping structure. Its bottom is fixed to the top of the workbench 1 via a fixing column 33, ensuring the overall structure is stable and reliable. Multiple limiting grooves 32 are provided on the top of the mounting plate 16 to guide the sliding direction of the connecting rod 14, ensuring the stability and accuracy of the clamping mechanism.

A connecting rod 14 is slidably connected inside the limiting groove 32, reciprocating within the groove to drive the clamping plate 15 to open and close. A clamping plate 15 is fixedly connected to the end of the connecting rod 14 away from the connecting column 10. The clamping plate 15 is used to clamp shaft-like parts to ensure stable positioning during processing. A protective mechanism is provided on one side to prevent damage to the surface of the parts when fixing them. A limiting post 31 is fixedly connected to the end of the connecting rod 14 away from the clamping plate 15. The limiting post 31 is used to transmit motion and guide the connecting rod 14 to move synchronously when the turntable 11 rotates. Multiple sliding grooves 17 are opened on the top of the turntable 11. The sliding grooves 17 provide sliding tracks for the limiting post 31 to realize the opening and closing linkage of the clamping structure.

The top of the limiting post 31 is fixedly connected to the limiting plate 27, and the bottom of the limiting plate 27 abuts against the top of the turntable 11. This is to ensure that the limiting post 31 can slide inside the slide groove 17, prevent it from falling off, and ensure the stability and guidance of the structure during the sliding process.

[0025] Please see the appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 The lubrication mechanism includes an oil reservoir 5 and a sleeve 9. The sleeve 9 is fixedly connected to the inside of the workbench 1 via a support plate 12. The oil reservoir 5 is installed inside the workbench 1. A spring 21 is installed inside the sleeve 9. A piston 20 is slidably connected inside the sleeve 9. A push rod 6 is fixedly connected to the side of the piston 20 away from the spring 21. A disc 19 is fixedly connected to the end of the push rod 6 away from the piston 20. A cam 23 is fixedly connected to the output end of the motor 7. The sleeve 9 and the oil reservoir 5 are fixedly connected via a connecting pipe 26. An oil outlet pipe 8 is fixedly connected to the outside of the sleeve 9. A one-way valve 22 is installed inside the oil outlet pipe 8. An electromagnetic one-way valve 25 is installed inside the connecting pipe 26. One end of the spring 21 is fixedly connected to the side of the piston 20 away from the push rod 6. The other end of the spring 21 abuts against the inner wall of the sleeve 9. The end of the oil outlet pipe 8 away from the sleeve 9 is located above the edge of the main gear 3. The surface of the disc 19 abuts against the cam 23. The push rod 6 is slidably connected inside the sleeve 9.

[0026] Specifically, the lubrication mechanism includes an oil reservoir 5 and a sleeve 9. The oil reservoir 5 stores lubricating oil to ensure the supply of lubricant required for long-term operation of the equipment. The sleeve 9 is fixedly connected to the inside of the workbench 1 via a support plate 12, providing a stable mounting base for the lubrication mechanism and supporting internal parts. A spring 21 is installed inside the sleeve 9, which provides a restoring force during the lubrication cycle, ensuring that the piston 20 can be reset. The piston 20 is slidably connected inside the sleeve 9. The piston 20 reciprocates under the combined action of the spring 21 and the rotation of the cam 23, realizing the intake and discharge of lubricating oil. A push rod 6 is fixedly connected to the side of the piston 20 away from the spring 21. The push rod 6 acts as a power transmission component, converting the rotational motion of the cam 23 into the linear sliding motion of the piston 20. A disc 19 is fixedly connected to the end of the push rod 6 away from the piston 20. The surface of the disc 19 abuts against the cam 23. The periodic push or release of the push rod 6 by the contour change of the cam 23 realizes the reciprocating motion of the piston 20. A cam 23 is fixedly connected to the output end of motor 7. Driven by motor 7, cam 23 rotates to provide periodic thrust to piston 20. Sleeve 9 and oil reservoir 5 are fixedly connected via connecting pipe 26, which serves as a channel for lubricating oil, used to transport lubricating oil from oil reservoir 5 to sleeve 9 during the oil suction phase. An electromagnetic check valve 25 is installed inside connecting pipe 26. The electromagnetic check valve 25 controls the flow direction and operation of the lubricating oil, ensuring that lubricating oil can only enter sleeve 9 from oil reservoir 5. When lubrication is not needed, the electromagnetic check valve 25 can automatically close to prevent backflow or leakage of lubricating oil. The electromagnetic check valve 25 can be set to open once a month for five minutes each time. An oil outlet pipe 8 is fixedly connected to the outside of sleeve 9, used to transport lubricating oil from sleeve 9 to main gear 3. A check valve 22 is installed inside oil outlet pipe 8, ensuring unidirectional flow of lubricating oil and preventing backflow from affecting lubrication. One end of the spring 21 is fixedly connected to the piston 20 on the side away from the push rod 6, and the other end abuts against the inner wall of the sleeve 9, providing a restoring force to ensure the normal normal operation of the piston 20. The end of the oil outlet pipe 8 away from the sleeve 9 is located above the edge of the main gear 3, ensuring that the lubricating oil can accurately drip into the meshing area between the main gear 3 and the secondary gear 18.

[0027] Please see the appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 and attached Figure 9 The protective mechanism includes a rubber pad 13. Multiple circular posts 30 are fixedly connected to the side of the rubber pad 13 near the clamping plate 15. Rubber rings 24 are fixedly connected to the outside of the circular posts 30. A circular hole 29 corresponding to the circular post 30 is opened on the side of the clamping plate 15 near the rubber pad 13. A groove 28 is opened inside the circular hole 29. The circular post 30 is slidably connected inside the circular hole 29, and the rubber ring 24 is engaged inside the groove 28.

[0028] Specifically, the protective mechanism includes a rubber pad 13, which is mounted on the clamping plate 15 to provide flexible cushioning when clamping shaft-like parts, preventing indentations or damage to the surface of the parts, thereby improving the safety and reliability of clamping. Multiple circular posts 30 are fixedly connected to the side of the rubber pad 13 near the clamping plate 15. The circular posts 30 are used to position and fix the rubber pad 13 to the clamping plate 15. A rubber ring 24 is fixedly connected to the outside of the circular posts 30. During installation, the rubber ring 24 forms an interference fit with the groove 28, enhancing the stability of the connection and preventing the rubber pad 13 from loosening or falling off during use. A circular hole 29 corresponding to the circular post 30 is provided on the side of the clamping plate 15 near the rubber pad 13. The circular hole 29 is used to accommodate the circular post 30, forming a plug-in fit structure, facilitating the quick installation and removal of the rubber pad 13. A groove 28 is provided inside the circular hole 29, which is used to embed the rubber ring 24, achieving snap-fit ​​positioning and further enhancing the installation firmness of the rubber pad 13 on the clamping plate 15. The circular column 30 is slidably connected inside the circular hole 29, allowing the rubber pad 13 to be easily inserted into or removed from the clamp 15, facilitating future replacement and maintenance.

[0029] Working principle: When using this equipment to machine shaft parts, first start the motor 7 to rotate it in the forward direction, driving the main gear 3 to rotate. Since the auxiliary gear 18 meshes with the main gear 3, the auxiliary gear 18 also rotates. As the auxiliary gear 18 rotates, the turntable 11 connected to it begins to rotate. At this time, the limiting post 31 will slide in the slide groove 17, driving the connecting rod 14 to move in the limiting groove 32 on the mounting plate 16.

[0030] As the turntable 11 continues to rotate, the clamping plates 15 gradually open outwards, allowing the operator to place shaft-like parts into the fixing mechanism formed by the clamping plates 15 in sequence. Subsequently, the control motor 7 rotates in the opposite direction, and the clamping plates 15 gradually close towards the center until the rubber pads 13 on the clamping plates 15 adhere to and are firmly fixed to the shaft-like parts.

[0031] After the fixation is completed, each automatic processing robot arm 2 begins to operate, performing turning processing on the shaft parts at the corresponding workstation.

[0032] To prevent wear on the main gear 3 and the secondary gear 18 due to prolonged operation, regular lubrication is required. Lubrication can be performed by opening the solenoid check valve 25. At this time, when the motor 7 is running, it drives the cam 23 to rotate. As the protruding part of the cam 23 moves away from the disc 19, under the action of the spring 21, the piston 20 slides outward from the sleeve 9, thereby drawing the lubricating oil in the oil reservoir 5 into the sleeve 9 through the connecting pipe 26.

[0033] When the cam 23 rotates until its protrusion contacts the disk 19, the piston 20 is pushed and compresses the spring 21, thereby squeezing out the lubricating oil in the sleeve 9 through the oil outlet pipe 8 and dripping it onto the edge of the main gear 3, thus lubricating the meshing point between the main gear 3 and the auxiliary gear 18. When the solenoid one-way valve 25 is closed, since nothing can be drawn from the oil reservoir 5, the piston 20 will not move due to the rebound of the spring 21 when the solenoid one-way valve 25 is closed, so the piston 20 will remain in the sleeve 9.

[0034] In addition, to avoid damaging the surface of shaft parts when clamping workpieces, a rubber pad 13 is provided on the clamping plate 15. This rubber pad 13 needs to be replaced periodically after prolonged use. When replacing it, simply remove the old rubber pad 13 from the clamping plate 15, insert the circular post 30 on the new rubber pad 13 into the circular hole 29 on the clamping plate 15, and simultaneously embed the rubber ring 24 into the groove 28 to form an interference fit, thus completing the replacement operation.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
