[0039] The hydraulic part comprises a worm 29 coaxially fixedly installed on the second gear 13, a threaded rod 30 is rotatably connected in the machine body 1, a worm wheel 31 is coaxially fixedly connected on the threaded rod 30, the worm wheel 31 is in meshing engagement with the worm 29, a driving frame 32 is slidably connected with the machine body 1 in the vertical direction, the threaded rod 30 penetrates through the driving frame 32 and is threadedly connected with the driving frame 32, a hydraulic rod 33 is fixedly connected on the driving frame 32, and the upper and lower ends of the hydraulic rod 33 are slidably connected with the inner walls of the first hydraulic cylinder 27 and the second hydraulic cylinder 28 respectively.

[0040] Working principle: the workpiece 44 is installed on the clamping piece 2 for fixation, select the appropriate tool bit 3, the plug-in rod 22 of the tool bit 3 is inserted into the plug-in hole 21, the slope groove 43 is pushed to one end of the clamping rod 40 by rotating the threaded ring 39, the clamping rod 40 is gradually inserted into the clamping groove 41 under the push, the second tension spring 42 is stretched, at this time the fixation of the tool bit 3 as a whole can be completed through the clamping rod 40, at this time the inner wall of the sliding tube 23 can wrap the outer wall of the tool bit 3, and in the process of driving, the tool bit 3 can be driven to rotate synchronously through the installation cylinder 20 and the sliding tube 23, the stability in the driving process is improved.

[0041] The driving motor 10 is started to drive the driving shaft 11 to rotate, please refer to the attached Figure 7 When the driving shaft 11 drives the second gear 13 to rotate clockwise, the control electric telescopic rod 37 pulls the plug-in block 38 to release the clamping with the triangular groove 36 at this time, the second gear 13 will exert a clockwise rotating thrust force on the third gear 14 and the fourth gear 15, so that the rotating disc 12 is deflected to the state shown in the attached Figure 3 The electric telescopic rod 37 is started to push the plug-in block 38 to insert into the deepest part of the triangular groove 36 and limit, the rotating disc 12 is rotated to the set angle and fixed through the sliding assistance between the slope of the triangular groove 36 and the side wall of the plug-in block 38 at this time, the third bevel gear 16 is engaged with the first bevel gear 4, and the fourth bevel gear 18 is engaged with the second bevel gear 5, because the fourth gear 15 is driven to rotate through the planetary gear reducer 17, the rotating speed of the third bevel gear 16 is much greater than that of the fourth bevel gear 18, so that the rotating speed of the first bevel gear 4 is greater than that of the second bevel gear 5, the first bevel gear 4 and the second bevel gear 5 drive the rotating rod 6 to rotate the first gear 7, the first gear 7 drives the outer gear ring 9 to rotate the rotating cylinder 8, the rotating cylinder 8 drives the lifting cylinder 19 and the installation cylinder 20 to rotate, so that the tool bit 3 can be rotated and operated, at this time the rotating speed of the upper tool bit 3 is much greater than that of the lower tool bit 3.

[0042] In the above case, the rotation of the second gear 13 also drives the worm 29 to rotate, the worm 29 drives the worm wheel 31 to rotate the threaded rod 30, the threaded rod 30 drives the driving frame 32 to move upwards, so that the hydraulic rod 33 moves upwards, pushes the hydraulic oil in the first hydraulic cylinder 27 into the rotating cylinder 8, so that the lifting cylinder 19 moves downwards, the first tension spring 26 is stretched, the lifting cylinder 19 drives the upper cutter 3 to move downwards, and the hydraulic rod 33 in the process of moving upwards increases the volume in the second hydraulic cylinder 28, so that the hydraulic oil in the lower rotating cylinder 8 is sucked into the second hydraulic cylinder 28, that is, the lower cutter 3 gradually moves away from the workpiece 44, and because the rotating speed of the upper cutter 3 is greater than that of the lower cutter 3 in this process, the rotating speed of the drill-in cutter 3 is fast and the hydraulic thrust is strong, and the other group of cutters 3 far away from the workpiece 44 slowly rotates and gradually exits from the inside of the hole of the workpiece 44. In the drilling process, the sliding pipe 23 on the outer wall of the cutter 3 will be in contact with the workpiece 44 through the rotating ring 25, so that the rotating ring 25 remains relatively fixed and does not affect the rotation of the sliding pipe 23 and the cutter 3, avoiding the abrasion of the top of the sliding pipe 23 to the surface of the workpiece 44. With the feeding of the cutter 3, the sliding pipe 23 gradually slides into the mounting cylinder 20, compressing the spring 24. In this process, the sliding pipe 23 sufficiently reduces the length of the exposed cutter 3, improving the stability of the cutter 3 during operation.

[0043] Similarly, when it is necessary to switch the operating state of the cutter 3, the plug-in block 38 is controlled by the electric telescopic rod 37 to release the limiting of the triangular groove 36, and the driving shaft 11 is controlled to rotate in the opposite direction. At this time, the rotating disc 12 can be reversely rotated by 180°, the limiting rod 35 slides to the bottom end position of the arc-shaped guide frame 34, and then the plug-in block 38 is controlled to limit and fix the triangular groove 36. At this time, the third bevel gear 16 is located below the fourth bevel gear 18, the third bevel gear 16 is engaged with the second bevel gear 5, and the fourth bevel gear 18 is engaged with the first bevel gear 4. Transmission can be achieved so that the rotating speed of the upper cutter 3 is much smaller than that of the lower cutter 3. Because the rotating direction of the second gear 13 is opposite, the rotating direction of the threaded rod 30 is opposite, and the driving frame 32 slides downward at this time, the first hydraulic cylinder 27 is in a suction state, and the second hydraulic cylinder 28 is in a pressurization state, so that the lower cutter 3 can realize the function of fast rotation and feeding, and the upper cutter 3 slowly rotates out of the hole. In this way, the operating states of the two groups of cutters 3 are switched back and forth, which can avoid the situation that a single group of cutters 3 runs for a long time, the temperature is too high, the service life is reduced, and the stability of the equipment is reduced. In addition, the two ends of the through hole can be machined by the two groups of cutters 3 respectively, the depth of feeding required by a single group of cutters 3 is shortened, and the stability of the cutter 3 during operation is improved.

[0044] It should be noted that the tool bit 3 in the scheme can be a drill bit or a boring tool, and the device only shows one of the processing methods, wherein the clamping piece 2 can be a mechanical arm or other fixed clamps installed on the moving table, and can also be a rotating table capable of driving the workpiece 44 to rotate and other existing structures. The tool bit 3 in the scheme is vertically arranged, and can also be horizontally arranged, and the rationality of the structure can be adjusted according to the needs, but the overall operation principle will not change greatly. The upper side of the lifting cylinder 19 is provided with a distance sensor, which can monitor the depth of the tool bit 3, that is, the distance of the lifting cylinder 19 moving, when the tool bit 3 advances to the set depth, the driving motor 10 can be controlled to reverse rotation, stop drilling and pull out the tool bit 3. The structure in the scheme is designed to realize the above-mentioned hole opening processing method. If there is a simpler and more stable structure that can realize the above-mentioned function, part of the structure in the scheme can be replaced with other structures that can realize the above-mentioned function.
