[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figure 1-8As shown, the specific design of the above-mentioned key components is described below: A high-precision boring device for automotive steering rocker arms includes a bracket 1, a lifting mechanism 2 above the bracket 1, a support plate above the lifting mechanism 2, electric cylinders 7 symmetrically arranged above the support plate, convex rails 27 symmetrically arranged above the support plate, a slider 28 slidably connected above the convex rails 27, a slide plate 6 above the slider 28, a driving plate 29 on the output end of the electric cylinder 7, one side of the driving plate 29 connected to the slide plate, a main motor 4 above the slide plate 6, a rotating shaft connected to the output end of the main motor 4 via a coupling 9, a boring tool 10 on the end of the rotating shaft away from the coupling 9, a bearing seat 8 above the slide plate 6, a rotating shaft penetrating through the bearing seat 8, a lower compartment 16 on the side of the bracket 1 away from the lifting mechanism 2, and a pull-out water tank inside the lower compartment 16. 2111, the lower chamber 16 serves to support the water receiving tank 2111 and the upper components. The water receiving tank 2111 is equipped with a filter screen 31. The treatment chamber 17 is located above the water receiving tank 2111. The bottom of the treatment chamber 17 has multiple drainage holes 19. The sides of the treatment chamber 17 have multiple mounting holes 18 with different vertical heights and different horizontal distances. The mounting holes 18 are connected to clamping components 20 by threads. The lifting mechanism 2 can adapt to the height requirements of different mounting holes 18 to better carry out boring operations. A water supply mechanism is located on one side of the bracket 1. The water supply mechanism is equipped with a nozzle 15 through the water pumping pipe 13. The nozzle 15 can directly spray cooling water onto the workpiece. The lower chamber 16 is connected to the water tank 11 through the discharge pipe 24. A clean water box 25 is installed on the discharge pipe 24. Multiple activated carbon plates 26 are installed in the clean water box 25.

[0028] The workpiece is fixed in the processing chamber 17 by the clamping assembly 20. During boring, the main motor 4 drives the boring bar 10 to rotate at high speed, and the electric cylinder 7 pushes the slide plate 6 to feed precisely along the cam rail 27. The processing chamber 17 closes the processing area to prevent debris from splashing. At the same time, the nozzle 15 sprays coolant to cool down and flush away the debris. The waste liquid mixed with debris flows into the pull-out water tank 2111 through the drain hole 19 at the bottom of the processing chamber 17. The filter screen 31 intercepts solid metal chips, achieving preliminary solid-liquid separation. After filtration, the liquid flows into the clean water box 25 through the feed pipe 24. The multi-layer activated carbon plate 26 absorbs the liquid. The coolant removes oil, particles, and chemical impurities, serving as a further filter and facilitating the reuse of wastewater for cooling spraying. The purified coolant flows back to the water tank 11 and is circulated by the water supply mechanism, forming a closed-loop cooling system. The processing chamber 17 physically isolates high-temperature debris, eliminating the risk of burns to personnel and greatly solving the problem of waste overflow, reducing the cleaning burden. The purified coolant maintains stable lubrication performance, reduces tool wear, and improves the surface finish of the hole wall, fundamentally solving the problem of coolant contamination and taking into account both safety, environmental protection, and high-precision machining requirements.

[0029] The lifting mechanism 2 includes an extension plate 3, a servo motor 201, a reduction motor 202, a screw jack 204, and a transmission shaft 203. The extension plate 3 is located on one side of the support 1. The servo motor 201 is positioned above the extension plate 3, and the reduction motor 202 is positioned above the support 1. The servo motor 201 and the reduction motor 202 are connected. The screw jack 204 is positioned at the four included corners above the support 1. The reduction motor 202 and the screw jack 204 are rotatably connected. The inside of the vertical tube of the support 1 is hollow, and the screw below the screw jack 204 passes through the inside of the support 1.

[0030] Servo motor 201 provides precise power, and after the torque is increased by geared motor 202, it drives four screw jacks 204 located at the included angles of bracket 1 to operate synchronously through transmission shaft 203. The screws of screw jacks 204 extend downward into the hollow tube inside bracket 1, driving the bearing plate and the processing unit above to move vertically as a whole, realizing precise adjustment of the height of boring tool 10. The combination of servo motor 201 and geared motor ensures the lifting speed to meet the processing requirements of different specifications of rocker arms. The synchronous drive of screw jacks 204 at the four included angles eliminates the risk of off-center load, and the bearing plate lifts and lowers smoothly, avoiding vibration from affecting the boring accuracy. The design of the screws being built into the hollow tube of bracket 1 strengthens the overall rigidity and compact layout of the structure. The lifting mechanism 2 achieves millimeter-level fine adjustment with closed-loop control, taking into account both high stability and compact design, providing a reliable foundation for high-precision boring.

[0031] The clamping assembly 20 includes a first threaded rod 2001, a U-shaped clamp 2002, a second threaded rod 2003, and a top plate 2004. The first threaded rod 2001 is installed in a mounting hole 18 on one side of the processing chamber 17. The U-shaped clamp 2002 is disposed on one end of the first threaded rod 2001. The second threaded rod 2003 is installed in a mounting hole 18 on one side of the processing chamber 17 and is disposed opposite to the first threaded rod 2001. The top plate 2004 is disposed on one end of the second threaded rod 2003. The workpiece is clamped between the U-shaped clamp 2002 and the top plate 2004.

[0032] The first threaded rod 2001 is screwed into the mounting hole 18 on the side wall of the processing chamber 17, pushing the U-shaped clamp against one side of the workpiece contour. The second threaded rod 2003 is screwed in from the opposite direction, driving the top plate 2004 to press the other side of the workpiece. By adjusting the screwing depth of the two threaded rods, the U-shaped clamp 2002 and the top plate 2004 can achieve bidirectional synchronous locking of the workpiece, adapting to steering rocker arms of different shapes and sizes. The U-shaped clamp 2002 fits the irregular curved surface of the rocker arm, and the top plate 2004 provides planar clamping force to prevent workpiece displacement or vibration. Multiple mounting holes 18 positions support arbitrary adjustment of the clamping point position, compatible with more models of rocker arms. The threaded rods can be manually fine-tuned, saving effort. This component achieves full-range clamping of irregular parts with a simple structure, combining high efficiency and high rigidity.

[0033] The water supply mechanism includes a water tank 11, a loading platform 23, a water pump 12, and a limiting tube plate 14. The water tank 11 is located on one side of the support 1, the loading platform 23 is located above the water tank 11, and the water pump 12 is located above the loading platform 23 and connected to the water tank 11. The end of the water pump pipe 13 away from the nozzle 15 is connected to the water pump 12. The limiting tube plate 14 is vertically located above the support 1, and the water pump pipe 13 is distributed along the limiting tube plate 14 and passes through the top of the limiting tube plate 14. The water pump 12 draws purified coolant from the water tank 11 and pumps it through the water pump pipe 13 to the nozzle 15 for spraying into the processing area. The limiting tube plate 14 acts as a clamp and guide, ensuring stable pipeline transmission and achieving the dual goals of stable coolant supply and long-term equipment operation. A stop bar 5 is provided on the rear side of the main motor 4. The stop bar 5 is designed to prevent the main motor 4 from moving too far backward and to prevent the main motor 4 and the slide plate 6 from falling off the convex rail 27. Baffles 30 are provided on both sides of the bearing plate. Limit bolts 32 are provided on the baffles 30. By installing the limit bolts 32 on the baffles 30, the driving plate 29 can be blocked to prevent the driving plate 29 from extending too far and to prevent the slide plate 6 from falling off the convex rail 27. A water outlet pipe 22 is provided on one side of the water tank 2111. The water tank 2111 allows water to be discharged from the discharge pipe 24 into the water tank 11. If the water in the water tank 2111 is not completely discharged from the discharge pipe 24, the water outlet pipe 22 can be opened to drain the water. Then the water tank 2111 can be pulled out to facilitate cleaning the debris on the filter screen 31.

[0034] The method of using this utility model is as follows: Screw in the first threaded rod 2001 to make the U-shaped clamp 2002 fit against the curved surface of the workpiece; screw in the second threaded rod 2003 in the opposite direction to push the top plate 2004 to press against the other side of the workpiece, achieving bidirectional rigid fixation; start the lifting mechanism 2, and the servo motor 201 drives the four-angle screw jacks 204 to synchronously adjust the height of the bearing plate; the electric cylinder 7 pushes the slide plate 6 along the convex rail 27 to select the correct position, ensuring that the axis of the boring tool 10 is precisely aligned with the hole to be machined; confirm that the stop bar 5 and the limit bolt 32 are in a safe position to prevent the slide plate 6 from derailing; start the water supply mechanism and pump water. 12. The purified coolant in the water tank 11 is guided to the nozzle 15 through the limiting tube plate 14 and sprayed into the cutting area. The main motor 4 is started to drive the boring tool 10 to rotate and perform boring operation. The splashing debris is blocked by the processing chamber 17. The waste liquid mixed with the coolant flows into the water receiving tank 2111 through the bottom drain hole 19. The filter screen 31 intercepts the metal chips. The liquid enters the clean water box 25 through the feed pipe 24. After the activated carbon plate 26 adsorbs impurities, it flows back to the water tank 11 for recycling. After the processing is completed, the water outlet pipe 22 on the side of the water receiving tank 2111 is opened to drain the residual liquid. The filter screen 31 is cleaned by pulling out the water receiving tank 2111.
