They are based on metal materials (such as iron, stainless steel, aluminum, copper, etc.) and are made through processes such as machining. They have characteristics such as high strength, wear resistance, and corrosion resistance. During the processing of metal fittings, a CNC machine tool is required for drilling;

[0003] There is a CNC machine tool for processing precision metal fittings of an automobile with the Chinese patent publication number CN114603182A. In this prior art, a transmission device is fixedly installed in the middle of the front of the fixed shaft. Tightening disks are movably installed at both ends of the transmission device.

A rotating shaft is fixedly installed in the middle of the rotating gear. A strong magnet is movably sleeved in the middle of the sliding groove. An electromagnet is fixedly installed inside the inner cavity. By adopting the cooperative installation of the rotating disk and the fixed shaft, a rotating groove is opened on the rotating disk and a rotating sleeve is movably installed, and a tool holder is movably installed inside the rotating sleeve, making tool change convenient and the drilling effect good;

[0004] For the above-mentioned device and the existing CNC machine tools for processing metal fittings, during use, the drilling depth on the metal fittings cannot be reasonably and precisely controlled, resulting in the drilling depth on the metal fittings being either too deep or too shallow. Especially when drilling is required at different positions on the metal fittings, the drilling depth needs to change continuously, making it impossible to precisely control and monitor the hole depths drilled at each position. At the same time, after the metal fittings are fixed, they cannot be fully placed horizontally, severely affecting the drilling depth during the drilling process, and being easily affected by debris that is inconvenient to clean during the drilling process. Therefore, a CNC machine tool for precise and rapid processing of metal fittings is needed to improve the above problems. Summary of the Invention

[0015] The beneficial effects of the present invention:

[0016] 1. The present invention adjusts and positions the metal fittings to be drilled horizontally and vertically by means of the provided adjustment and limit main body, specifically through the first movement adjustment part and the second movement adjustment part in the adjustment and limit main body. This enables precise drilling at various positions on the metal fittings, ensuring accurate drilling positions. Meanwhile, the provided dust suction support frame can guide and discharge the debris generated during drilling. Additionally, through the provided monitoring part, the first detection partition main body, and the second detection partition main body, automatic detection and monitoring of the drilling depth can be achieved during the drilling process of the metal fittings, ensuring accurate drilling depths. Moreover, according to different drilling depths, the use and operation of the monitoring part, the first detection partition main body, and the second detection partition main body can be adaptively adjusted and controlled.

The second motor can drive the fourth electric push rod to rotate, and the fourth electric push rod can control the lifting and adjustment of the detection swing arm to adjust the height of use. As a result, the detection swing arms in the first detection partition main body and the second detection partition main body can scan above both ends of the metal fitting. Each second laser distance sensor evenly installed on the detection swing arm can detect the distance between both ends of the metal fitting. If the distances detected by the detection swing arms in the first detection partition main body and the second detection partition main body are the same, it indicates that the metal fitting is in a horizontal state and can be stably drilled. Conversely, if there is an inclination at both ends of the metal fitting, it needs to be adjusted before drilling to ensure that the metal fitting is placed in a horizontal state during drilling.

[0033] As Figure 6As shown, the first movable adjustment part 16 and the second movable adjustment part 17 both include a support and limit base 24, and the inclined support frame 22 is symmetrically fixedly installed on both sides of the support and limit base 24, and the driving gear 23 is rotatably installed inside the upper end of the inclined support frame 22, and the support and limit base 24 is rotatably clamped between the upper ends of the inclined support frame 22, and the two ends of the support and limit base 24 are fixedly connected to the middle part of the driving gear 23, and the outer end of the inclined support frame 22 located on one side is fixedly installed with a first motor 25, and the driving end of the first motor 25 is fixedly connected to the middle part of the driving gear 23, and the upper end of the support and limit base 24 is slidably clamped with a sliding adjustment plate 28, and driving connecting plates 27 are fixedly installed on both sides of the sliding adjustment plate 28, and the outer bottom end of the driving connecting plate 27 is fixedly connected with a moving tooth plate 26, and the moving tooth plate 26 is meshed with the upper end of the driving gear 23.

During the drilling process, it is connected with the external jet equipment through the connecting pipe 31, so that each nozzle 29 can spray during the drilling process of the drill bit 13, so that the debris generated during the drilling process is blown off from the metal fittings 3, so that the debris does not affect the drilling as much as possible. The pressure value detected by the pressure sensor 36 is adapted to the drilling depth of different depths. The specified pressure value is detected to accurately correspond to the depth of the drilling, so that the depth of the drilling is converted into a pressure value for display detection and accurate and convenient control.

[0035] like Figures 8-9As shown, both the first detection partition main body 4 and the second detection partition main body 8 include a limit partition detection disc 44. A sliding carriage 45 is fixedly connected to the outer end of the limit partition detection disc 44. The bottom end of the third electric push rod 38 is fixedly connected to the sliding carriage 45. A fourth electric push rod 42 is fixedly installed on the upper part of the side of the limit partition detection disc 44 facing away from the sliding carriage 45. A second electric motor 43 is fixedly installed on the bottom of the side of the limit partition detection disc 44 facing away from the sliding carriage 45, and the driving end of the second electric motor 43 is fixedly connected to the bottom end of the fourth electric push rod 42. A detection swing arm 41 is fixedly connected to the upper end of the fourth electric push rod 42. Second laser distance sensors 39 are evenly fixedly installed at the bottom of the detection swing arm 41. A wiring terminal 40 is fixedly arranged at the upper end of the detection swing arm 41. The third electric push rod 38 can adaptively control and precisely adjust the use partition position of the limit partition detection disc 44, so as to block and intercept the detection extrusion disc 37 that moves downward together with the drill bit 13. Moreover, the detection extrusion disc 37 and the pressure sensor 36 arranged on both sides of the monitoring part 9 are used in combination with the first detection partition main body 4 and the second detection partition main body 8, which can make the detection and control more precise.

[0036] The sliding carriages 45 in the first detection partition main body 4 and the second detection partition main body 8 are respectively slidably clamped inside both sides of the processing machine case 2. The third electric push rods 38 in the first detection partition main body 4 and the second detection partition main body 8 are respectively fixedly installed outside both sides of the processing machine case 2. The outer end of the sliding carriage 45 is directly above the first laser distance sensor 6. The clamping installation frame 30 is adapted to the lifting wire barrel 10, and the clamping installation frame 30 is clamped on the lifting wire barrel 10. The fixing installation bolt 32 is threadedly inserted into the internal of the installation threaded hole 11. The dust suction support frame 18 is fixedly installed at the bottom end inside the processing machine case 2. The first electric push rod 21 is fixedly connected to the sliding adjustment plate 28 in the second moving adjustment part 17. The upper end of the first electric push rod 21 is fixedly connected to the support limit base 24 in the first moving adjustment part 16. The detection extrusion disc 37 is directly above the limit partition detection disc 44, and the limit partition detection disc 44 can accurately detect the blocking and limiting of the detection extrusion disc 37.

[0037] Working principle: Open the sealing door on the processing chassis 2, and then place the metal fitting 3 to be drilled on the sliding adjustment plate 28 in the first moving adjustment part 16. Center the metal fitting 3 by observing the scale lines arranged on both sides of the sliding adjustment plate 28 in the first moving adjustment part 16. Fit and partition and limit both sides of the metal fitting 3 by screwing the limit partition plates 14 slidably arranged at both ends of the sliding adjustment plate 28 in the first moving adjustment part 16, and lock and fix the limit partition plates 14 by screwing the locking threaded posts 15, so that metal fittings 3 of different specifications and sizes can be stably limited, realizing stable drilling. During the drilling process, the drill bit 13 rotates and lifts to drill the metal fitting 3. During the drilling process, the first motors 25 in the first moving adjustment part 16 and the second moving adjustment part 17 operate, and the driving gear 23 can be synchronously rotated by means of the arranged support and limit base 24. The rotating driving gear 23 can make the sliding adjustment plate 28 slide respectively by means of the moving tooth plate 26 and the driving connecting plate 27. Since the first moving adjustment part 16 and the second moving adjustment part 17 are arranged in a staggered manner, the metal fitting 3 can be slidably adjusted horizontally and vertically. And starting the first electric push rod 21 can adjust the height of the metal fitting 3, so that the drilling position on the metal fitting 3 is accurate, and continuous drilling treatment can be realized at different positions;

[0038] When different depths of drill holes need to be drilled on or at different positions of the metal fitting 3, parameters are transmitted to the control display screen in the CNC machine tool main body 1. At this time, the third electric push rods 38 in the first detection partition main body 4 and the second detection partition main body 8 run synchronously, driving the sliding carriage 45 to lift a specified distance along the processing machine case 2, thereby driving the limit partition detection disc 44 to move to a specified position. And the first laser ranging sensor 6 set can detect and monitor the distance between the bottom end of the sliding carriage 45 in real time, and transmit the detected data to the controller in the CNC machine tool main body 1. Finally, the operation of the third electric push rod 38 is indirectly controlled and adjusted. According to the different depths of the drill holes, the limit partition detection disc 44 is accurately moved to the specified working position. When drilling, the lifting screw barrel 10 in the CNC machine tool main body 1 will move downward, driving the rotating drill bit 13 to move downward for drilling. And during the downward movement of the lifting screw barrel 10, it will drive the clamping installation frame 30 and the support arm 33 in the monitoring part 9 to move downward synchronously, so that the buffer protection spring 35, the pressure sensor 36 and the detection extrusion disc 37 move downward, making the detection extrusion disc 37 contact and compress the buffer protection spring 35 with the limit partition detection disc 44. At this time, the pressure sensor 36 can detect the extrusion force. When the pressure sensor 36 detects the pressure value corresponding to the specified depth of the drill hole, at this time, the CNC machine tool main body 1 is controlled to stop the drill bit 13 from continuing to move downward for drilling, so that the depth of the drill hole is accurate and will not be drilled too shallow or too deep. And this device can calibrate and adjust parameters during the drilling process, making the device accurate and sensitive during use. And when the positions at different positions on the metal fitting 3 or the depth of the drill hole changes, the third electric push rod 38 can adaptively control and accurately adjust the use partition position of the limit partition detection disc 44, so as to intercept and block the detection extrusion disc 37 that moves downward together with the drill bit 13. The second electric push rod 34 can adaptively adjust the use position of the detection extrusion disc 37. And the detection extrusion disc 37 and the pressure sensor 36 arranged on both sides of the monitoring part 9 are used in combination with the first detection partition main body 4 and the second detection partition main body 8, which can make the detection and control more accurate, and can realize drilling of different depths. And during the drilling process, it is connected to an external air jet device through the connecting pipe 31, so that each nozzle 29 jets air during the drilling of the drill bit 13, so that the debris generated during the drilling process is blown off from the metal fitting 3, so that the debris has as little impact on the drill hole as possible. The blown-off debris will fall into the inside of the dust suction support frame 18 through the dust suction hole 19, and each powerful blower 20 blows a uniform air body into the inside of the dust suction support frame 18, so that the debris is discharged into the inside of the chip discharge pipe 5 through the dust suction support frame 18 for blowing and collecting, making the debris convenient to collect and process;

[0039] During the use of the first detection partition main body 4 and the second detection partition main body 8, the second motor 43 is started. The fourth electric push rod 42 can be driven to rotate by the second motor 43, and the height of the detection swing arm 41 can be adjusted by lifting and lowering through the fourth electric push rod 42, so as to control the detection swing arm 41 in the first detection partition main body 4 and the second detection partition main body 8 to scan the upper parts of both ends of the metal fitting 3. Each second laser distance sensor 39 evenly installed on the detection swing arm 41 can detect the distance between both ends of the metal fitting 3. If the distances detected by each detection swing arm 41 in the first detection partition main body 4 and the second detection partition main body 8 are the same, it indicates that the metal fitting 3 is in a horizontal state and can be drilled stably. On the contrary, it indicates that both ends of the metal fitting 3 are tilted and need to be adjusted before drilling.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
