Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a mechanical drilling device. Background Technology

[0002] In the field of machining and manufacturing, drilling is an extremely common process. Whether it is precision drilling in the manufacturing of aerospace components to reduce structural weight and meet the design requirements of high strength and lightweight, or machining various holes in engine blocks, transmission housings, etc., in the processing of automotive parts to achieve the assembly and functionality of components, the requirements for machining drilling equipment are constantly increasing with the development of the manufacturing industry.

[0003] Existing equipment often employs rudimentary mechanical control mechanisms for feed control, making it difficult to control the drill bit's descent speed and position. This leads to issues such as significant hole size deviations, low positional accuracy, and failure to meet surface roughness standards during drilling. Secondly, the workpiece clamping methods are inadequate. Traditional clamping devices typically have a simple structure, making it difficult to adapt to workpieces of different shapes and sizes. The operation of clamping components is not flexible enough; some are simply fixed clamps, which can reduce drilling accuracy and have limited adaptability. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a machining drilling device, comprising a base and a frame. The frame is arranged in an inverted U-shape and includes a drilling feed component and a drilling execution component. The drilling feed component includes a servo motor mounted on the top of the frame, with a guide screw connected to the output end of the servo motor. The guide screw passes through the frame and is rotatably connected to the base at its bottom. A vertical block is threadedly connected to the outer side of the guide screw. A vertical plate is fixed on the base, and the outer wall of the vertical block contacts the outer wall of the vertical plate. The drilling execution component includes a drive motor mounted on the bottom of the vertical block, with a rotating rod connected to the output end of the drive motor. A drill bit is connected to the bottom of the rotating rod. A clamping component is also provided, including two clamping plates on the left and right sides. The bottom of the clamping plates is slidably connected to the base. A groove is provided on the frame for the clamping plates to slide. A center block is fixed on the top of the frame, with adjusting screws rotatably connected to the two side walls of the center block. The two adjusting screws are threadedly connected to the two clamping plates, respectively.

[0005] Furthermore, a cooling component for cooling the drill bit is provided. The cooling component includes a centrifugal pump, the output end of which is connected to an output pipe. A cooling channel is opened inside the rotating rod, with both the upper and lower ends of the cooling channel passing through the rotating rod. The top end of the cooling channel is connected to the output pipe.

[0006] Furthermore, a chip removal trough is provided on the top of the base, extending to both ends of the base, and recycling bins are provided on both sides of the base.

[0007] Furthermore, the lower end of the rotating rod is connected to the drill bit via a Morse taper to facilitate the replacement of drill bits of different specifications.

[0008] Furthermore, the outer wall of the clamping strip is engraved with graduations.

[0009] Furthermore, a rotating shank is fixed to the section of the adjusting screw away from the center block, and a rubber shock-absorbing pad is fixed to the bottom of the base.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The servo motor precisely controls the rotation speed of the guide screw, thereby controlling the descent position and speed of the vertical block. Simultaneously, it achieves stable feed control through cooperation with the drilling feed component. Referring to the scale on the outer wall of the clamping plate, it can also assist in controlling the feed position, reducing drilling dimensional deviations and effectively improving the surface roughness of the hole. The rotating rod and drill bit are connected using a Morse taper, greatly facilitating drill bit replacement. When switching to different drill bit specifications to adapt to different hole diameter processing tasks, the operator simply needs to remove the original drill bit from the rotating rod and then install the new drill bit according to the Morse taper fit requirements. This connection method is not only simple and quick to operate but also ensures the installation accuracy of the drill bit, guaranteeing the concentricity and stability of the drill bit during rotation.

[0012] 2. The clamping components enable more flexible and precise workpiece clamping and positioning. The two clamping plates on the left and right sides slide on the base via adjusting screws, accommodating workpieces of different shapes and sizes. This reduces machining errors caused by improper workpiece clamping and improves product yield.

[0013] 3. The design of the cooling components effectively solves the heat dissipation problem during drilling. A centrifugal pump delivers coolant to the cooling channels inside the drill bit, allowing the coolant to directly act on the heat-generating parts of the drill bit, promptly removing the large amount of heat generated by friction. This not only reduces the drill bit temperature and extends its service life, reducing the cost of frequent drill bit replacements, but also prevents a decrease in workpiece machining accuracy due to drill bit overheating, such as avoiding burns on the hole wall and changes in the material's microstructure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] A machining drilling device, such as Figure 1 As shown, the device includes a base 1 and a frame 2. A rubber shock-absorbing pad 10 is fixed to the bottom of the base 1. The frame 2 is arranged in an inverted U-shape and is equipped with a drilling feed component and a drilling execution component. The drilling feed component includes a servo motor 301 mounted on the top of the frame 2. The output end of the servo motor 301 is connected to a guide screw 302. The guide screw 302 passes through the frame 2 and is rotatably connected to the base 1 at its bottom. A vertical block 303 is threadedly connected to the outer side of the guide screw 302. A vertical plate 304 is fixed on the base 1, and the outer wall of the vertical block 303 contacts the outer wall of the vertical plate 304. The drilling execution component includes a drive motor 401 mounted on the bottom of the vertical block 303. The output end of the drive motor 401 is connected to a rotating rod 402. The lower end of the rotating rod 402 is connected to a drill bit 403 through a Morse taper to facilitate the replacement of drill bits 403 of different specifications.

[0021] The system is supported and damped by a base 1, while the frame 2 provides installation space. A servo motor 301 feeds the drill bit via a guide screw 302 and a vertical block 303. A vertical plate 304 provides guidance, and a rotating rod 402 connects to the drill bit 403 via a Morse taper for easy drilling and bit changing. The damping pad ensures stability, reduces wear and noise, precise feed control improves processing quality and efficiency, and the Morse taper facilitates drill bit 403 switching, enhancing the equipment's adaptability.

[0022] like Figure 1 As shown, in this embodiment, a clamping component is also provided, including two clamping strips 501 on the left and right. The bottom of the clamping strips 501 is slidably connected to the base 1. A sliding groove for the clamping strips 501 to slide is provided on the frame 2. A center block 502 is fixed on the top of the frame 2. Adjusting screws 503 are rotatably connected to the two side walls of the center block 502. The two adjusting screws 503 are threadedly connected to the two clamping strips 501 respectively. A rotating handle 9 is fixed to the section of the adjusting screw 503 away from the center block 502. The outer wall of the clamping strips 501 is engraved with a scale 8.

[0023] The clamping bar 501 slides on the base 1, is guided by the slide groove of the frame 2, and cooperates with the adjusting screw 503 via the center block 502. The rotating handle 9 rotates to achieve clamping, and the scale 8 assists in the feed operation. It can adapt to clamping workpieces of various shapes, prevent displacement and deformation, improve the pass rate and production efficiency, and reduce costs.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, a cooling component 6 is provided to cool the drill bit 403. The cooling component 6 includes a centrifugal pump, the output end of which is connected to an output pipe 601. A cooling channel 602 is provided inside the rotating rod 402. Both the upper and lower ends of the cooling channel 602 pass through the rotating rod 402, and the top end of the cooling channel 602 is connected to the output pipe 601. A chip removal groove is provided on the top of the base 1, and the chip removal groove extends to both ends of the base 1. A recycling box 7 is provided on both sides of the base 1.

[0025] The centrifugal pump delivers coolant through output pipe 601 and cooling channel 602 to cool the drill bit 403, while the chip removal groove guides the chips to the recovery box 7. Cooling extends the life of the drill bit 403 and prevents workpiece deformation, while chip removal avoids chips affecting processing, ensuring processing continuity and stability, and improving quality and efficiency.

[0026] The working principle of this utility model is as follows:

[0027] First, place the workpiece to be processed on the base 1. Then, according to the workpiece's dimensions, rotate the rotating handle 9 on the adjusting screw 503. Since the adjusting screw 503 is threadedly connected to the clamping plates 501 and rotatably connected to the side wall of the center block 502, when the adjusting screw 503 is rotated, the two clamping plates 501 will slide relative to or away from each other along the grooves on the base 1. This securely clamps the workpiece onto the base 1, ensuring that the workpiece will not shift during the drilling process.

[0028] Next, the servo motor 301 is started, and its output drives the guide screw 302 to rotate. The outer side of the guide screw 302 is threadedly connected to the vertical block 303, and the outer wall of the vertical block 303 contacts the outer wall of the upright plate 304. Under the rotation of the guide screw 302, the vertical block 303 begins to move downward along the axial direction of the guide screw 302. The drive motor 401 mounted at the bottom of the vertical block 303 also descends accordingly. The displacement of the control drilling feed component can be observed through the scale 8 on the outer wall of the clamping plate 501.

[0029] Then, the drive motor 401 is started, and the output end of the drive motor 401 drives the rotating rod 402 to rotate, which in turn causes the drill bit 403 connected to the lower end of the rotating rod 402 to rotate at high speed. Under the continuous drive of the servo motor 301, the vertical block 303 drives the rotating drill bit 403 to gradually approach the workpiece and begin the drilling operation.

[0030] During the drilling process, a centrifugal pump is started, which delivers coolant through the output pipe 601 to the cooling channel 602 inside the rotating rod 402. The coolant flows in the cooling channel 602, absorbing the heat generated by friction in the drill bit 403, and then flows out from the lower end of the cooling channel 602, cooling the drill bit 403 and the machining area, effectively reducing the temperature of the drill bit 403, reducing wear on the drill bit 403, and ensuring machining accuracy.

[0031] Meanwhile, the debris generated during drilling will fall into the chip removal groove opened at the top of the base 1. Since the chip removal groove extends to both ends of the base 1, the debris can slide along the chip removal groove into the recycling bins 7 on both sides of the base 1, thus preventing the debris from accumulating in the processing area and affecting the processing.

[0032] When it is necessary to change to a different specification of drill bit 403, since the rotating rod 402 and the drill bit 403 are connected by a Morse taper, the drill bit 403 can be easily and quickly disassembled and replaced to meet the processing requirements of different hole diameters.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
