A CNC drilling and milling machine tool

Abstract

The present invention relates to the technical field of drilling and milling machines, and specifically to a CNC drilling and milling machine, comprising a square pipe provided on a passive delivery assembly in the drilling and milling machine and a drilling and milling drive head provided on a hydraulic rod, characterized in that it also comprises a pressure-bearing side bending mechanism provided on the drilling and milling drive head, an anti-collision protection mechanism provided outside the pressure-bearing side bending mechanism, and a position control mechanism provided directly below the drilling and milling drive head. By arranging the drilling and milling cutter and the drilling and milling drive head in a movable plug-in manner, when the drilling and milling drive head descends and causes the drilling and milling cutter to continue to descend, once the pipe moves during the drilling and milling process and causes the drilling and milling cutter to have eccentric pressure, the two sets of pressure measuring and calibration mechanisms that first receive the pressure can apply a back-boring force to the drilling and milling cutter along the moving direction of the pipe, and finally ensure that the drilling and milling cutter can be pulled out from the drilling and milling drive head before the pipe is pressed, thereby preventing the drilling and milling cutter from breaking due to excessive eccentric pressure.

Description

Technical Field

[0002] Drilling and milling machine tools, also known as CNC gantry drilling and milling machines, can realize operations such as drilling through holes and blind holes on single-material parts and composite materials. The machine tools are mainly controlled through the cloud. Within the effective range, the drilling and milling cutter heads can perform precise drilling and milling processing on workpieces made of the above materials.

[0003] The drilling and milling machine consists of a workbench, a mobile gantry, a drilling and milling power head and protective devices. Different from the processing of single-sided workpieces, pipe workpieces are passively delivered and move directly under the drilling and milling power head. Once the moving speed of the pipe workpiece is unbalanced, the drilling and milling cutter head that descends and presses on the pipe will deviate from the center due to the above problems and its own high speed, and then a cutter collision will occur, that is, the drill bit or milling cutter will break. The broken drilling and milling cutter head will splash outward at a high speed, and the pipe workpiece will also be cracked due to the influence of the drilling and milling cutter head.

[0004] In view of this, a CNC drilling and milling machine tool was designed to solve the problem that the drilling and milling power head deviates from the center and continues to rotate, thus causing serious safety accidents. Summary of the invention

When the drill and milling drive end head descends and causes the drill and milling cutter to continue to descend, once the pipe fitting moves during the drilling and milling process and causes eccentric pressure on the drill and milling cutter, the two sets of pressure measuring and calibration mechanisms that first receive the pressure can apply a back-boring force to the drill and milling cutter along the moving direction of the pipe fitting, and ultimately ensure that the drill and milling cutter can be pulled out of the drill and milling drive end head before the pipe fitting is pressed, thereby avoiding the drill and milling cutter from breaking due to excessive eccentric pressure.

[0032] 2. The present invention arranges a bearing in the middle of the drill and milling cutter and arranges an independent pressure-bearing platform outside the bearing. Once the drill and milling cutter is withdrawn from the drill and milling drive end, the drill and milling cutter which still has a certain rotation speed may be affected by gravity and bend sideways under the auxiliary support of the pressure-bearing platform, and will eventually be attracted by the multiple magnetic blocks built into the two sets of suction bases, thereby ensuring that the drill and milling cutter can maintain an absolutely safe distance from the pipe fitting after withdrawal, thereby avoiding damage to the pipe fitting.

[0033] 3. The present invention arranges an anti-collision protection mechanism outside the pressure-bearing side bending mechanism. At this time, the anti-collision protection mechanism will be located outside the two groups of pressure measuring and calibration mechanisms. Once the inclination angle between the drilling and milling drive end and the pipe fitting continues to increase and causes the drilling and milling cutter to fail to withdraw in the first time, multiple groups of mother plates and sub-plates with a rectangular structure can block the waste chips generated by the drilling and milling cutter and the pipe fitting, thereby effectively improving the safety of the working area.

DETAILED DESCRIPTION

[0051] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0052] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0053] A CNC drilling and milling machine tool provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0054] Embodiment 1:

[0055] Combination Figure 1-Figure 10As shown, a CNC drilling and milling machine tool provided by the present invention includes a square pipe 100 arranged on a passive delivery component in the drilling and milling machine tool and a drilling and milling drive head 200 arranged on a hydraulic rod, and is characterized in that it also includes a pressure-bearing side bending mechanism 300 arranged on the drilling and milling drive head 200, an anti-collision protection mechanism 400 arranged outside the pressure-bearing side bending mechanism 300, a positioning mechanism 500 arranged directly below the drilling and milling drive head 200, and two groups of pressure measuring and calibration mechanisms 600 arranged on the pressure-bearing side bending mechanism 300. The drilling and milling drive head 200 is used to carry the positioning mechanism 500 down and perform drilling and milling operations on the drilling and milling drive head 200. The pressure-bending mechanism 300 is used to support the anti-collision protection mechanism 400 and the two groups of pressure measuring and calibration mechanisms 600. The anti-collision protection mechanism 400 is used to block the splashing of waste chips and the splashing of broken drilling and milling cutters. The pressure measuring and calibration mechanism 600 is used to calibrate and protect the pressure in the moving direction of the drilling and milling cutter.

[0056] The pressure-bearing side bending mechanism 300 includes a sleeve 310 mounted on the drilling and milling drive end head 200, two shaft sleeves 320 mounted on the sleeve 310, and two sets of suspensions 330 mounted on the sleeve 310;

[0057] The anti-collision protection mechanism 400 is used to provide anti-sputtering protection for the drilling and milling drive end 200 and the surface of the square pipe 100;

[0058] The position control mechanism 500 includes a drilling and milling cutter 510 disposed at the bottom end of the drilling and milling drive end head 200, a first bearing 530 and a second bearing 560 mounted on the rod body of the drilling and milling cutter 510, and two clamps 540 mounted outside the first bearing 530;

[0059] Two sets of pressure measurement calibration mechanisms 600 are arranged between the two sets of suspensions 330, and are used to provide calibration protection for the lateral deflection transmission of the drilling and milling drive end head 200 in real time;

[0060] The pressure measurement calibration mechanism 600 includes a traction member 610 movably connected to the clamp 540, a load-bearing frame 620 connected to the other end of the traction member 610, a pressure measurement leg 630 installed in the load-bearing frame 620, and a pad foot 640 with no dead angle installed at the bottom end of the pressure measurement leg 630.

[0061] During the actual operation of the drilling and milling machine, the passively delivered pipes move under the drilling and milling power head. Once the moving speed of the pipes is unbalanced, the drilling and milling power head pressed on the pipes will deviate from the center due to its own rotation speed, which will cause the drilling and milling cutter head to break. After the break, the drilling and milling cutter head still has a certain rotation speed, which will cause continuous damage to the pipes. At the same time, the broken drilling and milling cutter head and the waste chips generated by the pipes will be splashed into the surrounding environment under pressure, which will cause safety hazards to surrounding workers in serious cases.

[0062] The device is provided with a pressure-bending mechanism 300 on the conventional drilling and milling power head. At this time, two sets of pressure-measuring and calibrating mechanisms 600 installed directly below the pressure-bending mechanism 300 can be calibrated and protected against pressure along the two directions of the lateral movement of the drilling and milling drive end 200. Once the movement speed of the drilling and milling drive end 200 is unbalanced and the pressure of one set of pressure-measuring and calibrating mechanisms 600 increases, the pressure-measuring legs 630 will approach the drilling and milling cutter 510 under the reaction of the inclined pressure, thereby compressing the traction member 610. At this time, the traction member 610 at this location The guide piece 610 will push the drill and milling cutter 510 out of the drill and milling drive end 200, and under the continuous thrust, the drill and milling cutter 510's own gravity and the bearing capacity provided by the two slide seats 370, the withdrawn drill and milling cutter 510 will quickly bend sideways and will eventually be fixed by the two fixing machine seats 660. At this time, the drill and milling cutter 510 can be in an intact state without contacting the surface of the drill and milling drive end 200, thereby effectively protecting the safety of the drill and milling cutter 510 and at the same time not causing continuous damage to the drill and milling drive end 200.

[0063] Embodiment 2:

[0064] Combination Figure 3-Figure 10 As shown, based on the embodiment 1, the pressure-bearing side bending mechanism 300 further includes two cantilevers 340 installed in the two sets of suspension frames 330, a slideway is provided inside the cantilever 340, and two symmetrically distributed compression springs 350 are connected to the top and bottom of the inner side of the slideway;

[0065] The position control mechanism 500 further includes two second cushion members 550, and the two second cushion members 550 are fixedly mounted on the middle part of the rod body of the drilling and milling cutter 510;

[0066] The second bearing 560 is disposed between the two second cushion members 550 .

[0067] Preferably, the two cantilevers 340 cooperate with the two sets of compression springs 350 to form a double shock-absorbing protection, which can provide a side bending bearing platform for the two slides 370 and quickly reset the drill and milling cutter 510 during maintenance, thereby effectively preventing the drill and milling cutter 510 from falling due to high rotation speed problems and providing protection for the drill and milling drive end 200.

[0068] A first cushion member 520 is installed on the drilling and milling cutter 510 . The first cushion member 520 is fixed by bolts, and the first cushion member 520 is used to provide a stable pressure-bearing platform for the first bearing 530 .

[0069] The fixture 540 is composed of a ring buckle and an end plate, and a slot is opened in the middle of the end plate, and a combination bolt is arranged in the slot to provide an oiled mounting platform for the rotation of the drilling and milling cutter 510.

[0070] Preferably, the two clamps 540 are fixed by bolts. At this time, the two clamps 540 cooperate with the first bearing 530 to provide effective anti-shake protection for the drill and milling cutter 510. When the two traction members 610 are respectively connected to the two clamps 540, once one of the traction members 610 shrinks, the drill and milling cutter 510 can bend sideways along the direction of shrinkage of the traction member 610, thereby improving the safety of the drill and milling cutter 510 after it is detached.

[0071] The slide 370 is composed of a Y-shaped leg, a U-shaped slider, a screw and a butterfly nut, and the screw is movably installed in the first sleeve 360, and the U-shaped slider is adapted to be clamped on the outside of the cantilever 340;

[0072] A first sleeve 360 ​​is installed in the middle of the two compression springs 350;

[0073] A slide seat 370 is disposed in the first sleeve 360 ​​, and two slide seats 370 are welded to the outside of the second bearing 560 , so as to provide a side-bending pressure-bearing platform for the drilling and milling cutter 510 to withdraw from the drilling and milling drive end head 200 .

[0074] Preferably, two second pads 550 are installed on the rod body of the drill and milling cutter 510. At this time, the two second pads 550 will constrain the second bearing 560. After the two slide seats 370 are welded to the outside of the second bearing 560, the normal operation of the drill and milling cutter 510 will not be interfered with, and the jitter phenomenon during the rotation of the drill and milling cutter 510 can be further reduced.

[0075] Embodiment 3:

[0076] Combination Figure 3 As shown, based on the embodiment 1, the anti-collision protection mechanism 400 includes two end rods 410 and a beam frame 420 installed on the two end rods 410;

[0077] The two first motherboards 430 are mounted on the long rods of the beam frame 420 , and the four second motherboards 440 are evenly distributed on the two end rods of the beam frame 420 .

[0078] Preferably, the beam frame 420 is integrally adapted to the drilling and milling drive end head 200. According to the ability to cope with the impact of impurities and waste chips during drilling and milling, the materials selected for the first motherboard 430, the second motherboard 440, the first sub-plate 470 and the second sub-plate 480 are not unique. Therefore, when processing pipes of different materials, selecting the first motherboard 430, the second motherboard 440, the first sub-plate 470 and the second sub-plate 480 of different pressure-resistant materials can provide higher safety protection for the working area of ​​the machine tool.

[0079] Limiting rods 450 are installed in the grooves outside the first motherboard 430 and the second motherboard 440 , and springs 460 are arranged outside the limiting rods 450 .

[0080] Preferably, the number of additional limit rods 450 is selected according to the length of the first mother plate 430 and the second mother plate 440. By increasing the number of limit rods 450 and springs 460, the smoothness of the free lifting and lowering of the first sub-plate 470 and the second sub-plate 480 is improved. At the same time, the arc-shaped structure at the bottom end of the first sub-plate 470 and the second sub-plate 480 can reduce the wear on the surface of the pipe.

[0081] Embodiment 4:

[0082] Combination Figure 3-Figure 10 As shown, in the above embodiment, the pressure measurement calibration mechanism 600 further includes a pressing assembly 670 connected between the load-bearing frame 620 and the traction member 610, and a truss 680 installed in the suspension 330, an elliptical slide groove is provided inside the truss 680, and a reset assembly 690 is provided in the elliptical slide groove;

[0083] The reset assembly 690 is composed of an extended second compression spring and a shaft sleeve.

[0084] Nuts for pressing the shaft sleeve are arranged on the threaded sections at both ends of the load-bearing frame 620 , and a through hole is opened inside the load-bearing frame 620 .

[0085] Preferably, the two load-bearing frames 620 are both cross-shaped structures. When the two load-bearing frames 620 are located on the left and right sides of the drilling and milling cutter 510 and cooperate with the moving direction of the drilling and milling drive end 200 to provide calibration protection, once the drilling and milling drive end 200 deviates from the center position due to its own problems, the two sets of pressure measurement calibration mechanisms 600 can evacuate the drilling and milling cutter 510 for this purpose;

[0086] When the moving speed of the drilling and milling drive head 200 is unbalanced, the two sets of pressure measuring and calibrating mechanisms 600 will quickly withdraw the drilling and milling cutter 510 due to the pressure.

[0087] The threaded section at the top of the pressure measuring leg 630 is adapted to penetrate into the through hole;

[0088] A compression spring 650 is disposed outside the threaded section at the top of the pressure-measuring leg 630 and is subjected to pressure from the load-bearing frame 620;

[0089] The pressing assembly 670 includes an inner support rod 671 movably connected to the inner clamping plate of the load-bearing frame 620, and the other end of the inner support rod 671 is movably installed in the transverse groove inside the traction member 610;

[0090] A slide 673 is movably mounted on the column head of the inner support rod 671 close to the traction member 610 , and a sub-spring 672 is arranged between the inner support rod 671 and the slide 673 .

[0091] Preferably, the clamping assembly 670 arranged between the load-bearing frame 620 and the traction member 610 can provide restoring kinetic energy for the retracted pressure measuring leg 630. At the same time, the inner support rod 671 of the rated length can prevent the traction member 610 and the load-bearing frame 620 from retracting at too large an angle, and provide stable rotation protection for the drill and milling cutter 510. The two symmetrical sets of clamping assemblies 670 can provide double auxiliary pressure protection for the vertically downward drill and milling cutter 510 under a constant pressure state.

[0092] The pressure measuring leg 630 is made of stainless steel, and a suction fixing machine base 660 is provided on the inclined rod of the pressure measuring leg 630;

[0093] A U-shaped groove adapted to be snap-fitted to the bottom end of the drilling and milling cutter 510 is provided at the bottom of the suction and fixing machine base 660 , and two magnetic blocks are arranged inside the suction and fixing machine base 660 .

[0094] Preferably, the height of the suction and fixing machine base 660 on the inclined rod of the pressure measuring leg 630 can be freely selected. After the height of the suction and fixing machine base 660 is adjusted according to the side bending angle of the drilling and milling cutter 510, once the drilling and milling cutter 510 is separated due to equipment failure or pipe stall, the two specifications of the suction and fixing machine base 660 can provide double protection for the drilling and milling cutter 510 after the side bending;

[0095] The no-dead-angle pad 640 arranged at the bottom end of the pressure measuring leg 630 can effectively reduce the pressure of the first sub-plate 470 and the second sub-plate 480 on the pipe during its no-dead-angle movement along the pipe surface, while preventing the pipe surface from being worn.

[0096] Working principle and use process of the present invention: At present, drilling and milling machine tools are mainly used for processing workpieces with thickness within an effective range, such as flanges, discs, rings and pipes. Different from independent plate structures, pipe-type structure workpieces need to be frequently adjusted to rotate when being processed by drilling and milling machine tools. At the same time, the accuracy of drilling and milling on each surface of the pipe-type workpiece also needs to be effectively regulated;

[0097] In the drilling and milling of pipe workpieces, the pipe workpieces are usually relatively long overall, and some of them are processed in a passive delivery manner on the drilling and milling machine. Once the speed of the passively delivered pipe is unbalanced, the drill and milling cutter that descends and fits on the pipe will break due to sudden eccentric pressure and the interference of its own high speed. The most obvious accident is that the drill and milling cutter drills into the pipe and breaks, causing pipe waste to splash.

[0098] The device sets the traditional drilling and milling cutter assembly method as the instruction manual Figure 4The drilling and milling drive head 200 and the drilling and milling cutter 510 structure are provided, and a sheath 310 is arranged on the outside of the drilling and milling drive head 200. At this time, after the sheath 310 is fixed, it can provide a pressure-bearing platform with sufficient pressure resistance for the anti-collision protection mechanism 400 as a whole, and the two groups of first motherboards 430, first sub-boards 470 and four groups of second motherboards 440 and second sub-boards 480 evenly distributed in a rectangular structure can provide protection against waste chip splashing for the drilling and milling operation of the drilling and milling cutter 510, and at the same time, it can provide effective blocking for the drilling and milling cutter to break off the center, so as to avoid the drilling and milling drive head 200 metal waste caused by the break of the drilling and milling cutter 510 causing safety hazards to the surrounding environment;

[0099] After the anti-collision protection mechanism 400 is arranged, the two groups of pressure measuring and calibrating mechanisms 600 arranged between the two groups of suspensions 330 can be arranged on the path of the left and right sides of the drilling and milling cutter 510 that bears pressure. When the drilling and milling drive end 200 is passively delivered and moves horizontally, the two groups of pressure measuring and calibrating mechanisms 600 arranged on the left and right can shrink toward the drilling and milling cutter 510 at the moment of receiving the off-center pressure. At the same time, the first bearing 530 drives the load-bearing frame 620 to approach the drilling and milling cutter 510, and the traction member 610 connected to the load-bearing frame 620 will Push one of the clamps 540 to drop downward until the drill and milling cutter 510 quickly withdraws from the drill and milling drive end 200. At the moment the drill and milling cutter 510 withdraws, the two slides 370 will drive the drill and milling cutter 510 to drop slightly, and finally bend sideways quickly under the influence of the gravity of the plug at the top of the drill and milling cutter 510. At this time, the multiple magnetic blocks built into the two suction machine bases 660 can suction and fix the drill and milling cutter 510 after side bending, thereby effectively ensuring that the device can perform absolutely safe drilling and milling operations on the surface of the square pipe 100, thereby reducing the risk of breakage of the drill and milling cutter 510.

[0100] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
