[0047] Example 1

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the present invention provides an overhead boring device, comprising a frame assembly, an overhead boring head assembly, a linear reciprocating drive assembly, and a tooling assembly. The tooling assembly is disposed on the top of the frame assembly and fixes the product to be processed. The linear reciprocating drive assembly is disposed on the frame assembly and drives the overhead boring head assembly to reciprocate along the height direction. The overhead boring head assembly includes a boring bar 25, a hydraulic tool holder 24, and a waterproof spindle 5. The boring bar 25 is connected to the output shaft of the waterproof spindle 5 via the hydraulic tool holder 24. The boring bar 25 extends into the top of the frame assembly, and the waterproof spindle 5 drives the boring bar 25 to rotate.

[0049] The waterproof spindle 5 of this application integrates a motor to perform the cutting rotation motion of the tool. The linear reciprocating drive component can drive the tilting boring head component to perform reciprocating motion in the height direction and perform vertical up and down cutting motion. The tilting design is particularly suitable for boring operations on the bottom or inverted surface, and can be widely used in underwater operations, medical devices, industrial inspection, scientific research experiments and other fields.

[0050] The hydraulic tool holder 24 and the waterproof spindle 5 are connected by a flange. To ensure the accuracy of the waterproof spindle 5 is within 0.005, the spindle uses symmetrical adjustment of the accuracy (roundness adjustment) with set screws on all four sides. After the roundness adjustment reaches the required accuracy, it is locked by end face locking. The vertical accuracy is designed to be within 0.01. It can also perform linear cutting motion machining in multiple stages and at multiple speeds. The waterproof spindle 5 is equipped with a water cooling inlet 20 and a water cooling outlet 22 for water cooling. The waterproof spindle 5 is also equipped with a spindle connection port 21, which is waterproofed.

[0051] Specifically, the frame assembly serves as the mounting base for the overhead boring head assembly, the linear reciprocating drive assembly, and the tooling assembly. It possesses sufficient structural strength, and the frame assembly is made of waterproof and corrosion-resistant materials, such as aluminum alloy. The outer shell uses high-strength waterproof materials (such as ABS+TPU composite material), achieving an overall protection rating of IP68. The main structure of the frame assembly is a rectangular hollow structure. In one feasible embodiment, the frame assembly includes a base plate 19, support rods 1, and an upper mounting plate 4. The upper mounting plate 4 and the base plate 19 are arranged parallel and spaced apart. The support rods 1 are fixedly installed between the upper mounting plate 4 and the base plate 19. Both the base plate 19 and the upper mounting plate 4 are rectangular plates, and one support rod 1 is provided at each of the four corners of the base plate 19 and the upper mounting plate 4. The support rods 1 are fixedly connected to the base plate 19 or the upper mounting plate 4 using fasteners such as screws and bolts, or by adhesive bonding.

[0052] More specifically, the linear reciprocating drive assembly includes a servo cylinder 32, a reducer 33, a coupling 34, and a lead screw pair. The length direction of the guide rail of the lead screw pair is in the same direction as the height direction of the frame assembly. The output shaft of the servo cylinder 32 is connected to the input shaft of the reducer 33, and the output shaft of the reducer 33 is connected to the lead screw 36 of the lead screw pair via the coupling 34. A lifting plate 2 is fixedly connected to the slider 37 of the lead screw pair, and a waterproof spindle 5 is fixedly mounted on the lifting plate 2. The lead screw pair is waterproofed by a waterproof cover 29 of the lead screw 36 module.

[0053] The threaded screw assembly includes a screw 36 and a slider 37. A frame assembly serves as the mounting base for the threaded screw assembly. The frame assembly includes a screw fixing block 35 and a screw support block 12. The bottom of the screw 36 is rotatably connected to the screw support block 12 via a bearing, and the top of the screw 36 is rotatably connected to the screw fixing block 35 via a bearing. The screw 36 passes through the slider 37 and is threadedly engaged with it. A lifting plate 2 is fixedly connected to the slider 37. In one feasible embodiment, the lifting plate 2 includes a central recessed platform for supporting the waterproof spindle 5. Mounting protrusions are provided on both sides of the central recessed platform, and at least one mounting protrusion on one side of the central recessed platform is fixedly connected to the slider 37 of the threaded screw assembly. The mounting protrusions and the slider 37 are fixedly connected by fasteners such as screws and bolts.

[0054] Furthermore, in a preferred embodiment, a slide rail and a sliding block are provided on the other side of the boring head assembly at a position symmetrical to the linear reciprocating drive assembly. The length direction of the slide rail is the same as the length direction of the lead screw 36. The mounting protrusion on the other side of the central recessed platform is fixedly connected to the sliding block by fasteners.

[0055] Furthermore, the threaded screw assembly also includes a guide rail, the length of which is parallel to the length of the screw 36. The guide rail mates with the slider 37, and is a roller guide rail 3, guiding the slider 37 to slide along the length of the screw 36. The frame assembly also includes a vertical plate 30, which is fixedly connected to the base plate 19. The guide rail of the threaded screw assembly is fixedly connected to the vertical plate 30 via a locking block 31 on the side of the guide rail. In one feasible embodiment, the upper surface of the base plate 19 has a mounting groove, and the bottom of the vertical plate 30 is embedded in the mounting groove and fixedly connected by fasteners. It should be noted that the width of the mounting groove is precisely matched with the width of the vertical plate 30 for bolt and pin hole connection, ensuring that the two are perpendicular to each other. The guide rail side locking block 31 is connected to the vertical plate 30. The vertical plate 30 and the guide rail side locking block 31 are perpendicular, and the guide rail is tightly against the guide rail side locking block 31 to ensure the guide rail is perpendicular before being tightened with screws. This ensures the connection accuracy of the guide rail, vertical plate 30, and base plate 19. Considering the connection accuracy of the guide rail slider 37 and the lifting plate 2, a guide rail side locking plate 18 is designed on the side of the guide rail slider 37 to adjust the accuracy between the two. Point adjustment is adopted, which can achieve fast and accurate results. The guide rail side locking plate 18 focuses on adjusting the accuracy of the guide rail slider 37, and adopts a surface-to-surface contact method. This equipment uses roller guide rail 3, and the accuracy of the equipment is evaluated by the accuracy of the guide rail itself, and then by the accuracy of the equipment structure. The slider 37 of the threaded screw pair is fixedly connected to the lifting plate 2 through the guide rail side locking plate 18.

[0056] The waterproof spindle 5 is connected by being supported by the lifting plate 2, which makes it easier to adjust the verticality of the spindle and facilitates disassembly. The servo cylinder 32 is equipped with a reducer 33, which is suitable for processing products with different torques. The threaded screw pair adopts a traditional connection mode, with a coupling 34 to alleviate shaft runout, which greatly reduces and improves the accuracy compared with similar products. The screw fixing block 35 and the screw support block 12 are specially designed according to the axis center of the servo cylinder 32, which can fix the screw 36, reduce the runout of the screw 36, and maximize the energy efficiency of the screw 36.

[0057] More specifically, the tooling assembly includes a tooling base plate 7, a first contour block 8, a second contour block 10, a miniature hydraulic cylinder 11, and a support block 12. The tooling base plate 7 is fixedly installed on the top of the frame assembly, and the tooling base plate 7 has a through hole in the middle that allows the boring tool 25 to pass through.

[0058] At least one of the first contour block 8 and the second contour block 10 is fixedly installed on the tooling base plate 7, and both the first contour block 8 and the second contour block 10 act on the contour of the product to be processed. The first contour block 8 and the second contour block 10 prevent the product from being misaligned.

[0059] At least one support block 12 is fixedly installed on the tooling base plate 7, and the support block 12 is used to support the bottom of the product to be processed. At least one set of miniature hydraulic cylinders 11 is provided on the tooling base plate 7, and the miniature hydraulic cylinders 11 press and fix the product to be processed on the tooling base plate 7.

[0060] Adjusting plugs and adjusting locking blocks are provided between the tooling base plate 7 and the top plate of the frame assembly. The adjusting plugs and adjusting locking blocks work together to adjust the concentricity and verticality of the tooling base plate 7 and the overhead boring head assembly. Fasteners are also provided between the tooling base plate 7 and the top plate of the frame assembly to detachably connect the tooling base plate 7 and the top plate of the frame assembly. The adjusting plugs include a first adjusting plug 13 and a second adjusting plug 28, and the adjusting locking blocks include a first adjusting locking block 14 and a second adjusting locking block 27. The first adjusting plug 13 cooperates with the first adjusting locking block 14, and the second adjusting plug 28 cooperates with the second adjusting locking block. The first adjusting plug 13 and the second adjusting plug 28 are located on two adjacent sides of the tooling base plate 7, respectively. Fine adjustments are made using the adjusting plugs, and after adjustment, the adjusting locking blocks are used to tighten them. The tooling base plate 7 is equipped with locking screws around its perimeter. After the precision is adjusted, the tooling is finally locked, which facilitates adjustment and helps to ensure accuracy. The servo waterproof cover 9 uses a stainless steel threaded hole locking connection. Around the threaded hole, a non-standard molded sealing ring is used to lock the servo waterproof cover 9 in a rectangular shape for waterproof sealing.

[0061] The frame assembly is also equipped with saponification liquid outlet pipes 15. At least one set of saponification liquid outlet pipes 15 is located at the top of the frame assembly, facing the area where the product to be processed is located. These outlet pipes, positioned at the top of the frame assembly and surrounding the boring bar 25, significantly enhance the removal of processing chips, allowing for simultaneous processing, chip removal, and tool cooling. The saponification liquid outlet pipes 15 cool the processed product, improve its surface finish, and also protect the tool, preventing built-up edge from affecting product dimensions and surface finish.

The motor performs chip processing according to the angle, speed, machining depth, and retraction speed set by the driver. The screen has a password control function. It can be connected to a smartphone or host computer via Bluetooth / Wi-Fi for remote control.

[0071] Based on the hardware foundation of Embodiment 1, a feasible usage method is as follows:

[0072] Preparation stage: Select and install the appropriate drill bit according to the processing requirements; turn on the power of the equipment and set parameters such as rotation speed and depth through the APP or control panel.

[0073] Positioning and securing: Place the equipment at the location to be processed, ensuring that the boring head is aligned with the target point; if it is an underwater operation, confirm that all sealing structures are intact.

[0074] Start processing: Start the motor and the equipment will start running automatically; the system provides real-time feedback on processing data, and users can monitor the progress through the APP.

[0075] End and Reset: The machine will automatically stop after processing is complete; turn off the power, remove the boring bar 25 and clean the equipment; if storing for a long time, it is recommended to store it in a dry place and charge it regularly.
