DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] See also Figure 1-5 , the present invention provides a technical solution: a universal high-precision milling and drilling device with a milling head rotation and positioning function, comprising a base 1, a workbench mechanism and a universal drill mechanism;

[0025] The top of the base 1 is fixedly connected with a fixed block 2, the top of the fixed block 2 is vertically fixedly connected with a plurality of electric control telescopic rods, the tops of the plurality of electric control telescopic rods are fixedly connected with a mounting plate 15, and the universal drill mechanism is arranged at the top of the mounting plate 15;

[0026] The universal drill mechanism includes a first device frame 16 and a support plate 17 which are vertically fixedly connected to the upper surface of the mounting plate 15, the surfaces of the first device frame 16 and the support plate 17 on opposite sides are both rotatably connected with a connecting shaft 18, a second device frame 19 is fixedly connected between the two connecting shafts 18, one end of the connecting shaft 18 on the surface of the first device frame 16 rotatably passes through the first device frame 16 and extends to the inside thereof, a first motor 21 is laterally fixedly connected to the bottom end inside the first device frame 16, a driving pulley 22 is fixedly connected to the surface of the output shaft of the first motor 21, a driven pulley 20 is fixedly connected to the surface of the connecting shaft 18 and located inside the first device frame 16, and the driving pulley 22 is connected to the driven pulley 20 through a belt drive;

[0027] A mounting hole 23 extending to the rear end of the second device frame 19 is provided on the front end surface thereof, and a mounting shaft 24 is rotatably connected inside the mounting hole 23. The front end and rear end of the mounting shaft 24 extend to the front and rear of the second device frame 19 respectively. A second motor 26 is transversely fixedly connected inside the second device frame 19, and a driving gear 27 is fixedly connected to the surface of the output shaft of the second motor 26. A driven gear 25 meshing with the driving gear 27 is fixedly connected to the surface of the mounting shaft 24 and located inside the second device frame 19, and a drilling and milling head 28 is fixedly connected to the front end of the mounting shaft 24.

[0028] In this embodiment, when the device is used to drill or mill a workpiece, the workpiece is first fixed on the workbench mechanism and the position of the workpiece is adjusted, and then the universal drill mechanism can be used to process the workpiece.

[0029] The universal drill mechanism fixes the drilling and milling head 28 at the front end of the mounting shaft 24. When drilling and milling the upper surface of the workpiece, the normal process can be followed. When drilling and milling the outer surface of the workpiece, the first motor 21 and the second motor 26 can be started. After the first motor 21 is started, the active pulley 22 on its output shaft rotates and drives the driven pulley 20 to rotate, thereby driving the connecting shaft 18 to rotate. When the connecting shaft 18 rotates, it can drive the second device frame 19 to rotate with the connecting shaft 18 as the center, thereby changing the inclination angle of the drilling and milling head 28 on the Z axis, and then controlling the drill bit in the drilling and milling head 28 to descend, so as to drill and mill the front and rear surfaces of the workpiece.

[0030] When the output shaft of the second motor 26 rotates, the driving gear 27 on the surface of the output shaft rotates and drives the driven gear 25 meshing with it to rotate, thereby driving the mounting shaft 24 to rotate. Since the drilling and milling head 28 is fixedly connected to the front end of the mounting shaft 24, it will rotate synchronously with the mounting shaft 24, thereby changing the inclination angle of the drilling and milling head 28 on the Y-axis, and then controlling the drill bit in the drilling and milling head 28 to descend, so as to drill and mill the surfaces on both sides of the workpiece.

[0031] Through the universal drill mechanism, the device can process grooves on various surfaces of the workpiece without repeatedly placing the workpiece, thereby improving the overall work efficiency.

[0032] Locking devices are provided on the connecting shaft 18 and the mounting shaft 24. Similar to the brake pads of a car, the connecting shaft 18 and the mounting shaft 24 are positioned. When the angle of the drilling and milling head 28 needs to be changed, the two locking devices will be unlocked. After the adjustment is completed, the connecting shaft 18 and the mounting shaft 24 will be locked again to prevent the drilling and milling head 28 from changing its angle due to force when milling the workpiece, thereby preventing accidents.

[0033] Furthermore, the workbench mechanism is arranged on the front end surface of the fixed block 2, and the workbench mechanism includes a support table 3 which is laterally fixedly connected to the front end surface of the fixed block 2, and a slide groove 4 is provided on the upper surface of the support table 3 along its length direction, and a first threaded rod 5 is rotatably connected inside the slide groove 4, and a plurality of first threaded sleeves 7 which are slidably connected to the inside of the slide groove 4 are threadedly connected on the surface of the first threaded rod 5, and a slider 6 is slidably connected to the upper surface of the support table 3 along its length direction, and a plurality of first threaded sleeves 7 are fixedly connected to the bottom end of the slider 6.

[0034] The workbench mechanism also includes a sliding hole 9 which is opened on the surface of the slider 6 along the length direction. A plurality of second threaded sleeves 10 are fixedly connected inside the sliding hole 9. A second threaded rod 11 is threadedly connected inside the plurality of second threaded sleeves 10. Both ends of the second threaded rod 11 extend to the outside of both ends of the slider 6 respectively. A working plate 12 is slidably connected to the top of the slider 6 along its length direction. Both ends of the lower surface of the working plate 12 are fixedly connected with mounting sleeves 13. Both ends of the second threaded rod 11 are rotatably connected to the inside of the two mounting sleeves 13 respectively.

[0035] The front end of the first threaded rod 5 passes through the support platform 3 and extends outward, and one end of the second threaded rod 11 passes through the mounting sleeve 13 and extends outward. The outer ends of the first threaded rod 5 and the second threaded rod 11 are both fixedly connected to the rotating disk 8.

[0036] In this embodiment, when using the device, the workpiece needs to be fixed by the workbench mechanism first, and then when the workpiece is milled, the position of the workpiece can be changed by the workbench mechanism to position the workpiece.

[0037] When the staff rotates the first threaded rod 5, the first threaded sleeve 7 threadedly connected on its surface will move along the length direction of the first threaded rod 5, thereby driving the slider 6 fixedly connected to the first threaded sleeve 7 to move. Since the first threaded rod 5 is arranged along the length direction of the support platform 3, the slider 6 will also move along the length direction of the support platform 3, and the working plate 12 at the top of the slider 6 will also move synchronously, thereby driving the workpiece to move forward and backward.

[0038] When the second threaded rod 11 is rotated, under the action of multiple second threaded sleeves 10, the second threaded rod 11 will move along the length direction of the slider 6. Since the two ends of the second threaded rod 11 are respectively rotatably connected to the inside of the two mounting sleeves 13, and the two mounting sleeves 13 are fixedly connected to the working plate 12, the working plate 12 can be driven to move along the length direction of the slider 6. The moving direction is perpendicular to the moving direction of the slider 6 on the support platform 3, that is, the workpiece is driven to move left and right.

[0039] When rotating the first threaded rod 5 and the second threaded rod 11, the rotating disk 8 at the outer ends of the two can be held to rotate. The rotating disk 8 improves the convenience of the device and is convenient for the staff to operate.

[0040] Furthermore, a telescopic dust cover 14 is provided between the fixing block 2 and the mounting plate 15 and outside the plurality of electrically controlled telescopic rods.

[0041] In this embodiment, the telescopic dust cover 14 can play a dustproof effect and protect the multiple electrically-controlled telescopic rods, preventing dust from entering the electrically-controlled telescopic rods and causing damage to the electrically-controlled telescopic rods, thereby increasing the service life of the device.

[0042] Furthermore, a plurality of mounting bars 30 are fixedly connected to the upper surface of the working plate 12 at even intervals along the length direction thereof.

[0043] In this embodiment, the mounting bar 30 is used to mount the workpiece, which is a prior art and will not be described in detail herein.

[0044] Furthermore, lighting lamps 31 and cooling water pipes 32 are respectively provided on both sides of the drill bit mounting seat of the drilling and milling head 28 .

[0045] In this embodiment, when the device is performing drilling and milling operations, the lighting lamp 31 can provide bright light so that the staff can see the state of the workpiece more clearly, and the cooling water pipe 32 can spray cooling liquid to prevent the drill bit from overheating and being damaged.

[0046] Furthermore, a plurality of supporting pads 29 are fixedly connected to the bottom end of the base 1 .

[0047] In this embodiment, the plurality of support pads 29 play a supporting role, lifting the entire device off the ground, and preventing the bottom of the device from being in contact with the ground for a long time and being worn.

[0048] The working principle and use process of the present invention are as follows: After the present invention is installed, the first motor 21 is started, and the active pulley 22 on its output shaft rotates and drives the driven pulley 20 to rotate, thereby driving the connecting shaft 18 to rotate. When the connecting shaft 18 rotates, it can drive the second device frame 19 to rotate with the connecting shaft 18 as the center, thereby changing the inclination angle of the drilling and milling head 28 on the Z axis, and then controlling the drill bit in the drilling and milling head 28 to descend, so as to drill and mill the front and rear side surfaces of the workpiece, and when the output shaft of the second motor 26 rotates, the active gear 27 on the surface of its output shaft rotates and drives the driven gear 25 meshing with it to rotate, thereby driving the installation shaft 24 to rotate. Since the drilling and milling head 28 is fixedly connected to the front end of the installation shaft 24, it will rotate synchronously with the installation shaft 24, thereby changing the inclination angle of the drilling and milling head 28 on the Y axis, and then controlling the drill bit in the drilling and milling head 28 to descend, so as to drill and mill the surfaces on both sides of the workpiece.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
