Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a novel CNC machining center. Background Technology

[0002] The new type of CNC machining center is an upgraded precision machining equipment based on the traditional CNC machining center, integrating modern advanced manufacturing technology, information technology and automation technology. The traditional CNC machining center refers to a CNC machine tool with an automatic tool magazine and automatic tool changer, which can complete multiple processes such as milling, drilling, boring and tapping on one machine. The "new type" emphasizes the leap in technical architecture, functional integration and intelligence. For example, the machine tool is equipped with an intelligent vision inspection module around the tool. The vision inspection module can monitor tool wear, tool position and posture, and automatic tool changing geometric error in real time, thereby improving the intelligence of the machine tool. Commonly used intelligent vision inspection modules mainly include industrial cameras, which are placed on the machine tool spindle box to monitor the cutting tool. However, most vision inspection modules are in relatively fixed positions, which limits the monitoring angle of the industrial camera to the position of the cutting tool's movement space. This makes it inconvenient to flexibly adjust the orientation of the vision inspection module to perform all-round inspection of the cutting tool and the machined parts on the machine tool table. Furthermore, cutting oil mist and chips are generated during machine tool processing. Most vision inspection modules lack oil mist and chip protection structures and camera resolution detection and calibration structures on the industrial camera. Contamination of the monitoring end of the industrial camera and irregular resolution calibration can easily affect the detection accuracy of the vision inspection module. Summary of the Invention

[0003] To address the technical problems of limited detection functions and inconvenient maintenance of existing CNC machine tool vision inspection mechanisms, this invention provides a novel CNC machining center.

[0004] The technical solutions provided by the embodiments of the present invention are as follows: This invention provides a novel CNC machining center, comprising a CNC machine tool and a testing box. The testing box has a cylinder fixed to its top, a mounting plate fixed to its output end, and a vision inspection module rotatably connected to the lower part of the mounting plate. The vision inspection module includes a suspension seat and a rotating seat. The upper end of the suspension seat is non-contactly placed inside the mounting plate, and the rotating seat is rotatably connected to the suspension seat. A drive assembly is provided between the rotating seat and the suspension seat. The drive assembly includes a worm, a worm wheel, and a universal joint. The worm wheel drives the rotating seat to rotate through the universal joint. The mounting plate has an annular flow channel, and the annular flow channel is provided with multiple constraint components that can constrain the rotation of the suspension seat. An industrial camera is installed inside the rotating base. A protective component is movably installed on one side of the rotating base near the industrial camera. The protective component includes a mounting ring and a protective lens. An annular air duct is fixed to one side of the rotating base. A connecting pipe is connected to one side of the annular air duct and the connecting pipe is connected to the annular diversion groove. The testing box is equipped with a calibration component and a maintenance component on both sides. The calibration component includes a calibration chamber and a test card, and the maintenance component includes a maintenance box and a cleaning turntable.

[0005] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: 1. By setting up a dual rotation structure, the suspension seat can be rotated as a whole and the rotating seat can be tilted and flipped. It can easily switch between two working conditions: vertical downward inspection of workpiece size and horizontal inspection of cutting tool. There is no need to add an independent vision inspection mechanism next to the machine tool processing table, which simplifies the machine tool peripherals and effectively reduces the overall equipment cost.

[0006] 2. By setting a limiting structure composed of baffles and stops, the rotation range of the suspension seat and the rotating seat can be limited to prevent over-rotation. At the same time, multiple clamping blocks are driven by air pressure to synchronously clamp the suspension seat, locking the rotational freedom of the suspension seat, effectively eliminating the problem of visual unit shaking during the detection process and improving detection stability.

[0007] 3. The design of sharing the air source synchronously supplies compressed air to the annular air duct, which allows the annular air outlet to continuously blow air onto the protective lens. This effectively isolates cutting oil mist from adhering to and contaminating the lens, continuously improving the clarity of visual inspection imaging and measurement accuracy. In addition, with the calibration and maintenance components, the camera can be calibrated by aligning with the existing test card after raising the vision unit. It can also easily perform cleaning operations on the protective lens, solving the problems of irregular camera calibration and lens contamination affecting the detection accuracy.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0023] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0024] like Figures 1 to 12As shown, this invention provides a novel CNC machining center, including a CNC machine tool 100 and a testing box 200. A conventional spindle box 110 is vertically mounted on the CNC machine tool 100. The testing box 200 is fixedly disposed on one side of the spindle box 110. A lifting assembly is provided inside the testing box 200, including a cylinder 210 and a mounting plate 230. A tool 111 is mounted on the lower end of the spindle box 110. The spindle box 110, using existing technology, can perform basic CNC machine tool 100 operations such as automatic tool changing of the tool 111. The cylinder 210 is vertically fixed at the upper center of the testing box 200. The telescopic rod at the output end of the cylinder 210 is movably inserted into the testing box 200. A vertically mounted... The guide rail 220 and the mounting plate 230 are vertically equipped with a slider on one side. The mounting plate 230 is movably connected to the guide rail 220 through the slider. The upper end of the mounting plate 230 is equipped with a U-shaped frame 231. The upper end of the U-shaped frame 231 is fixedly connected to the lower end of the telescopic rod of the cylinder 210. The detection box 200 is fixed to one side of the spindle box 110 by bolts. The mounting plate 230 is controlled to move up and down by the cylinder 210. In use, the telescopic rod of the cylinder 210 can push the mounting plate 230 to extend or retract into the detection box 200. During the up and down movement of the mounting plate 230, in addition to the telescopic rod of the cylinder 210, the combination of the guide rail 220 and the slider also makes the vertical up and down movement of the mounting plate 230 smooth and stable.

[0025] Please refer to Figure 5 , Figure 7 , Figure 8 and Figure 10 In this embodiment, a vision detection module 300 is rotatably connected to the mounting plate 230 via a drive assembly 400 below the mounting plate 230. The vision detection module 300 includes a suspension seat 310 and a rotating seat 320. The upper end of the suspension seat 310 is non-contactly placed inside the mounting plate 230. The rotating seat 320 is rotatably connected to the suspension seat 310 to complete the detection of changes in the orientation of the rotating seat 320. The upper end of the suspension seat 310 is inserted into the mounting plate 230 but does not contact the mounting plate 230. No resistance friction will be generated when the suspension seat 310 rotates later.

[0026] Furthermore, the drive assembly 400 includes a worm gear 410, a worm wheel 420, and a universal joint 440. An internal gear disc 321 is provided on one side of the rotating seat 320, and the internal gear disc 321 is rotatably connected to the suspension seat 310. The worm wheel 420 is connected to the internal gear disc 321 via the universal joint 440, thereby completing the movement control of the rotating seat 320. A lifting shaft is vertically provided at the lower center of the worm wheel 420, and the lifting shaft vertically passes through the center of the insertion mounting plate 230 via ball bearings and a thrust bearing. The suspension seat 310 has a first gear groove. The hoisting shaft of the worm gear 420 is rotatably inserted into the first gear groove and has an inner gear 430. The upper end of the mounting plate 230 is horizontally provided with a worm 410 through a bearing. One side of the worm gear 420 is meshed with the worm 410. The suspension seat 310 is suspended and installed through the hoisting shaft provided by the worm gear 420. The thrust bearing can support the force on the hoisting shaft of the suspension seat 310, ensuring that the worm gear 420 rotates normally on the mounting plate 230. Specifically, when the existing servo motor drives the worm gear 410 to rotate through the PLC control system, the worm gear 410 controls the worm wheel 420 to rotate. At this time, since the weight of the suspension seat 310 and the rotating seat 320 below are both attached to the lifting shaft of the worm wheel 420, the rotation of the worm wheel 420 can drive the suspension seat 310 and the rotating seat 320 to rotate together.

[0027] Please refer to Figure 10 and Figure 12 In this embodiment, the contact surfaces of the suspension seat 310 and the rotating seat 320 are both inclined surfaces. The suspension seat 310 has a second gear groove on its inclined surface. The inner gear disk 321 of the rotating seat 320 is rotatably inserted into the second gear groove of the suspension seat 310 through a bearing. A rotating groove is provided in the suspension seat 310 between the first gear groove and the second gear groove. The universal joint 440 is rotatably placed in the transmission groove through a bearing. The two sides of the universal joint 440 are respectively inserted into the first gear groove and the second gear groove and are provided with gear 441 and gear 442. One side of gear 441 and gear 442 are respectively meshed with inner gear disk 430 and inner gear disk 321. The contact inclined surfaces of the rotating seat 320 and the suspension seat 310 are both 45° inclined surfaces. At this time, the rotating seat 320 can rotate along the inclined surface, so that the suspension seat 310 and the rotating seat 320 are in a vertical posture or an L-shaped right angle arrangement.

[0028] Specifically, when the suspension seat 310 remains stationary, the worm gear 420 is driven to rotate through the worm 410. At this time, the worm gear 420 drives the internal gear disk 430 to rotate. When the internal gear disk 430 rotates, it drives the universal joint 440 connected to the gear 441 to rotate. Then, the gear 442 connected to the other end of the universal joint 440 pushes the internal gear disk 321 set on the rotating seat 320 to rotate, so that the rotating seat 320 can tilt and rotate on one side of the suspension seat 310, rotating from a vertical posture to an L-shaped engagement posture, so that the vision inspection module 300 can transform the workpiece on the vertical inspection processing table into the inspection tool 111.

[0029] Please refer to Figure 9 and Figure 10 In this embodiment, an annular flow divider 232 is formed within the mounting plate 230. Three constraint components 500 are inserted into the annular flow divider 232. Each constraint component 500 includes a movable rod 510, a clamping block 520, and a piston 530. The clamping block 520 is located on the side of the mounting plate 230 near the suspension seat 310. When the clamping block 520 contacts the suspension seat 310, it constrains the rotation of the suspension seat 310. Three receiving slots are formed in the mounting plate 230 near the suspension seat 310, and the clamping block 520 is movably inserted into the receiving slots. Piston slots are formed in the mounting plate 230 between the annular flow divider 232 and the receiving slots. The movable rod 510 horizontally passes through the piston slots. The annular diversion groove 232 and the receiving groove are connected. The clamping block 520 is connected to the side of the movable rod 510 located in the receiving groove. The side of the movable rod 510 located in the piston groove is provided with pistons 530. The side of the movable rod 510 located in the piston groove away from the annular diversion groove 232 is provided with compression springs 540. The side of the compression springs 540 abuts against the pistons 530. In the normal posture, the clamping block 520 will not contact the suspension seat 310. All three piston grooves are connected to the annular diversion groove 232. By introducing external high-pressure gas into the annular diversion groove 232, the clamping block 520 can be pushed to clamp the suspension seat 310, so that the mounting plate 230 and the suspension seat 310 are in a fixed posture.

[0030] Specifically, when it is necessary to constrain the rotation of the suspension seat 310, the annular diversion groove 232 is filled with high-pressure gas. The high-pressure gas pushes the piston 530 and the clamping block 520 to move towards the position of the suspension seat 310, clamping the position of the suspension seat 310 inserted into the mounting plate 230. At this time, the rotation of the worm gear 420 cannot drive the suspension seat 310 to rotate on its own, but can only drive the suspension rod and the stop rod 312 to rotate, thus completing the rotational movement control of the rotating seat 320. When the high-pressure gas in the annular diversion groove 232 is released, under the rebound action of the compression spring 540, the clamping block 520 moves away from the suspension seat 310. At this time, the rotation of the worm gear 420 can drive the suspension seat 310 and the rotating seat 320 to rotate on their own under the gravity of the suspension seat 310.

[0031] Please refer to Figure 8 , Figure 9 and Figure 11 An industrial camera 330 is housed within a rotating base 320. A protective component 600 is movably mounted on one side of the rotating base 320, comprising a mounting ring 610 and a protective lens 620. A movable groove 322 is formed on the side of the rotating base 320 away from the suspension base 310. The mounting ring 610 is movably inserted into the movable groove 322. A push ring 630 is provided on the side of the mounting ring 610 inserted into the movable groove 322. Sealing rings are provided on both the inner and outer circumferences of the push ring 630. The mounting ring 610 can extend and retract within the movable groove 322. The sealing rings allow high-pressure gas to be introduced into the movable groove 322, enabling the high-pressure gas to push the mounting ring 610 and move stably along the movable groove 322. Furthermore, the protective goggle 620 is fixedly mounted on one side of the mounting ring 610. When the mounting ring 610 moves, it drives the protective goggle 620 to move together. The push ring 630 is provided with a return spring 640, which is sleeved on the mounting ring 610. A constraint ring is provided on one side of the movable groove 322, and one side of the push ring 630 abuts against the constraint ring. When the high-pressure gas introduced into the movable groove 322 is released, the return spring 640 can push the mounting ring 610 to reset and abut against the constraint ring for positioning, so as to avoid excessive retraction.

[0032] Furthermore, an annular air duct 700 is fixedly provided on one side of the rotating seat 320, and a connecting pipe 710 is connected to one side of the annular air duct 700. The connecting pipe 710 is connected to the annular diversion groove 232. The annular air duct 700 is fixedly provided on one side of the rotating seat 320. The diameter of the annular air duct 700 is larger than the diameter of the protective mirror 620. An air outlet is opened on the inner circumference of the annular air duct 700. When one side of the mounting ring 610 contacts the constraint ring, the air outlet of the annular air duct 700 is flush with the protective mirror 620. The air outlet of the annular air duct 700 is annular. When the air outlet of the annular air duct 700 blows out high-pressure airflow, the high-pressure airflow can be evenly spread on the surface of the protective mirror 620, which can remove the oil mist generated during processing and improve the surface cleanliness of the protective mirror 620.

[0033] Furthermore, a conventional electric three-way ball valve 340 is provided on one side of the rotating seat 320. The two sides of the electric three-way ball valve 340 are respectively connected to the connecting pipe 710 and the movable groove 322. An air inlet and a one-way air outlet connector 233 are respectively provided at the upper and lower ends of one side of the annular diverter groove 232. A one-way valve is provided inside the one-way air outlet connector 233. A flexible hose 341 is connected to one side of the electric three-way ball valve 340. The other end of the flexible hose 341 is connected to the lower end of the one-way air outlet connector 233. The air inlet is connected to existing air compressor equipment, and air is compressed... The equipment sends high-pressure gas into the annular diversion channel 232. At this time, the high-pressure gas can push the clamping block 520 to clamp and constrain the suspension seat 310. When the pressure of the high-pressure gas continues to increase, the high-pressure gas can break through the one-way valve and the hose 341 and enter the electric three-way ball valve 340. At this time, the electric three-way ball valve 340 is controlled by the existing PLC to switch the gas connection, so that the high-pressure gas can enter the annular air duct 700 or the movable channel 322. When it enters the annular air duct 700, it can achieve the function of continuous air blowing and cleaning of the surface of the protective mirror 620.

[0034] Specifically, when the lens of the industrial camera 330 is vertically downward through the rotation of the rotating base 320, it can perform dimensional visual inspection of the workpiece above the worktable inside the CNC machine tool 100. When the industrial camera 330 is rotated through the rotating base 320 and faces the tool 111, it can perform visual inspection of the wear, position, and orientation deviation of the tool 111, thereby improving the processing efficiency and quality of the CNC machine tool 100. Furthermore, the high-pressure air source introduced through the annular duct 700 is shared with the air source of the annular diversion groove 232. When the camera 330 is being inspected, the clamping block 520 clamps the suspension seat 310, keeping the suspension seat 310 and the rotating seat 320 in a stable position, thus improving the accuracy of the inspection. At the same time, when the high-pressure gas enters the annular air duct 700 through the hose 341 and the electric three-way ball valve 340, it can block the cutting oil mist generated by the tool 111 during processing, preventing it from directly contacting the protective mirror 620. In addition, the protective mirror 620 and the mounting ring 610 can be disassembled independently, making it convenient for replacement and maintenance, and protecting the durability of the industrial camera 330.

[0035] Please refer to Figure 8 , Figure 10 and Figure 12In this embodiment, the upper and lower ends of both sides of the suspension seat 310 are provided with stop blocks 311, and one side of the rotating seat 320 is provided with a stop bar 323. When the protective mirror 620 of the rotating seat 320 is in a horizontal or vertical position, the stop bar 323 contacts the two stop blocks 311 respectively. One side of the suspension seat 310 is provided with a stop bar 312, and the lower end of the mounting plate 230 is provided with two stop blocks 234. After the suspension seat 310 rotates under the mounting plate 230, the two stop blocks 234 are respectively provided with a stop bar 311. Contacting the two stops 234, the rotation of the rotating seat 320 on the suspension seat 310 is limited by the abutment constraint of the second stop 311 and the second stop bar 323, so that the rotating seat 320 can only reciprocate in one direction, transforming it into visual detection for vertical orientation and visual detection for horizontal posture. The rotation of the suspension seat 310 in the mounting plate 230 is also limited to reciprocating in one direction under the cooperation of the first stop bar 312 and the first stop 234.

[0036] Please refer to Figures 4-6 In this embodiment, calibration components and maintenance components 800 are respectively provided on both sides of the test box 200. The calibration component includes a calibration cavity 240 and a test card 241. The calibration cavity 240 is located on the side of the test box 200 near the spindle box 110. The existing test card 241 is vertically inserted into one side of the calibration cavity 240 by screws. When the rotating seat 320 rotates and is in the vertical position of the suspension seat 310, the rotating seat 320 points towards the tool 111, and the hose 341, the rotating seat 320 and the second stop 311 are on the same plane. When the industrial camera 330 points to the tool 111, the cylinder 210 pulls the mounting plate 230 to rise. At this time, the orientation of the industrial camera 330 on the rotating seat 320 is inconvenient. When the industrial camera 330 reaches the position of the test card 241, it can be calibrated in conjunction with the calibration function built into the industrial camera 330. When the stop bar 312 abuts against one of the stops 234, the industrial camera 330 points in the direction of the tool 111 and the test card 241. The industrial camera 330 has a resolution of no less than 5 million pixels and a frame rate of ≥30fps.

[0037] It should be noted that the existing test chart 241 can be an ISO 12233 resolution test chart 241, specifically containing black and white wedge-shaped lines, star charts, Siemens stars, and other patterns. After the camera captures the image, the sharpness of the lines (MTF, modulation transfer function) is analyzed by an algorithm to obtain the resolving power data of a lens at different positions and directions. The detailed calibration principle will not be elaborated here.

[0038] Please refer to Figures 4-6In this embodiment, the maintenance component 800 includes a maintenance box 810 and a cleaning turntable 840. When the rotating seat 320 is perpendicular to the suspension seat 310, the test card 241 and the cleaning turntable 840 can cooperate with the rotating seat 320. The maintenance box 810 is fixedly installed on one side of the test box 200. A rotating liquid tank 820 is provided inside the maintenance box 810. The cleaning turntable 840 is rotatably installed inside the rotating liquid tank 820. An insertion window is provided through the maintenance box 810 inside the rotating liquid tank 820. The maintenance box 810 is located at the insertion window. An elastic sponge 860 is affixed to the position. The diameter of the insertion window is larger than the diameter of the rotating seat 320 but smaller than the diameter of the maintenance box 810. A blower shroud 830 is provided on the side of the maintenance box 810 away from the insertion window. A connecting shaft is located at the center of the cleaning turntable 840. The connecting shaft rotates through the blower shroud 830, and an existing impeller 850 is sleeved on the side of the connecting shaft located inside the blower shroud 830. When the protective goggle 620 still has surface contamination after long-term use, the suspension seat 310 can be rotated by the worm gear 420 to make the rotation... The rotating seat 320 is oriented towards the maintenance box 810. At this time, the stop lever 312 abuts against another stop block 234, and the cylinder 210 pulls the rotating seat 320 to rise. When the mounting plate 230 rises to its maximum extent, the rotating seat 320 and the protective mirror 620 align with the insertion window of the maintenance box 810. At this time, the electric three-way ball valve 340 sends the incoming high-pressure gas into the movable groove 322. Then, the mounting ring 610 pushes the protective mirror 620 into the rotating liquid groove 820 and into contact with the side of the cleaning disc 840. The cleaning disc 840 is equipped with a non-woven cleaning cloth at the contact point with the protective goggle 620. The bottom of the rotating liquid tank 820 is filled with electronic grade isopropyl alcohol of 99.7% or higher. When the cleaning disc 840 rotates, the bottom of the cleaning disc 840 is dipped in isopropyl alcohol and wipes the protective goggle 620 under the action of rotational sputtering. The rotation of the cleaning disc 840 is driven by high-pressure air introduced into the blower hood 830. After the high-pressure air enters the blower hood 830, it drives the impeller 850 to rotate, thereby realizing the cleaning rotation of the cleaning disc 840.

[0039] In addition, when no inspection is required, the rotating seat 320 can point towards the maintenance box 810 and come into contact with the elastic sponge 860. The elastic sponge 860, which deforms elastically, covers and protects the side of the rotating seat 320. The air source can be an air source pipe used on an external machine tool to blow away debris. The details of the pipe connection and air supply are not described here.
