The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0027] Referring to Figures 1 - 6 , an automated flexible drilling device, including a processing table 1 and a drill bit 6. Two concave plates 14 and a support base 13 are fixedly connected to the processing table 1. A bearing plate 5 is rotatably installed on the support base 13. Each concave plate 14 is connected to a sliding frame 4 through two springs 22. A T-shaped clamping plate 12 is fixedly connected to one side surface of the sliding frame 4. An electric push rod 17 is fixedly installed on the processing table 1. The driving end of the electric push rod 17 is fixedly connected to a concave rod 2. An extrusion rod 19 is fixedly connected to the concave rod 2. A through hole for connecting the extrusion rod 19 is provided on the support base 13. A rotating assembly is provided on each concave plate 14. The rotating assembly includes a rotating block 15 rotatably installed on the concave plate 14. A slider 3 is slidably installed on the rotating block 15. The slider 3 cannot be separated from the rotating block 15. Each slider 3 is hinged to the concave rod 2.

[0028] A reciprocating lead screw 10 is rotatably connected to the processing table 1. A bracket 11 is threadedly connected to the reciprocating lead screw 10. A telescopic rod 9 is fixedly connected to the bracket 11, and the telescopic rod 9 is fixedly connected to the processing table 1. A first hydraulic cylinder 23 is fixedly installed on the bracket 11. A fixed block 8 is fixedly connected to the driving end of the first hydraulic cylinder 23. A second hydraulic cylinder is fixedly installed in the fixed block 8. A rectangular block 20 is fixedly connected to the driving end of the second hydraulic cylinder. An installation block 7 is rotatably connected to the rectangular block 20. A first servo motor is installed in the rectangular block 20, and the driving end of the first servo motor is fixedly connected to the installation block 7. A second servo motor is fixedly installed on the processing table 1, and the driving end of the second servo motor is fixedly connected to the reciprocating lead screw 10.

[0029] During use, the second servo motor drives the reciprocating lead screw 10 to rotate, and the bracket 11 will move along the reciprocating lead screw 10. The telescopic rod 9 will simultaneously undergo telescopic deformation, so as to change the position of the drill bit 6 in one direction. The first hydraulic cylinder 23 drives the fixed block 8 to move, which can change the position of the drill bit 6 in another direction, facilitating the adjustment of the position of the drill bit 6 according to the actual usage situation. The second hydraulic cylinder drives the rectangular block 20 to move downward, which can change the vertical height of the drill bit 6. The first servo motor drives the installation block 7 to rotate, and the drill bit 6 will rotate along with it. During the process of the drill bit 6 rotating and moving downward, the workpiece on the bearing plate 5 can be automatically drilled.

[0030] A groove for connecting the drill bit 6 is provided on the installation block 7. The drill bit 6 is connected to the installation block 7 through a bolt 21. Thread grooves are provided on the inner wall of the groove. Insert the upper end of the drill bit 6 into the groove, and then make one end of the bolt 21 penetrate through the drill bit 6 and be threadedly connected to the thread groove, so that the drill bit 6 can be firmly connected to the installation block 7. Similarly, it is also convenient to disassemble and replace the drill bit 6.

[0031] An opening is provided on the processing table 1, and a storage basket 16 is arranged in the opening. A plurality of support columns 18 are fixedly installed at the bottom of the processing table 1. The cross-section of each support column 18 is in the shape of an isosceles trapezoid. The cross-section of the support column 18 is in the shape of an isosceles trapezoid, and the end with a larger cross-sectional area of the support column 18 contacts the ground, which can effectively increase the contact area with the ground, so as to facilitate the support column 18 to better support the processing table 1. A limiting strip is fixedly connected to the upper surface of the support seat 13, and the limiting strip fits the surface of the bearing plate 5. The limiting strip can limit the position of the bearing plate 5. When the surface of the bearing plate 5 fits the surface of the limiting strip, the bearing plate 5 is in a horizontal state.

[0032] In the present utility model, in the initial state, the bearing plate 5 is in a horizontal state, and each T-shaped clamping plate 12 is located outside the bearing plate 5. At this time, the workpiece is placed on the bearing plate 5. Then, the electric push rod 17 drives the concave rod 2 to move downward, and the extrusion rod 19 and the two sliders 3 will move downward together. During the downward movement of each slider 3, relative sliding will occur with the corresponding rotating block 15. The two rotating blocks 15 will rotate relative to the two concave plates 14 respectively. During the downward rotation of each rotating block 15, it will move along the surface of the corresponding sliding frame 4, thereby reducing the distance between the two sliding frames 4. Since one end of each spring 22 is fixedly connected to the corresponding sliding frame 4 and the other end is fixedly connected to the corresponding concave plate 14, the spring 22 is deformed. During the movement of the two T-shaped clamping plates 12, they will respectively be in close contact with the two side surfaces of the workpiece, thereby fixing the workpiece. At this time, the lower surface of each T-shaped clamping plate 12 is in contact with the surface of the bearing plate 5.

[0033] After drilling the workpiece, the electric push rod 17 drives the concave rod 2 to move upward, and the two sliders 3 move upward simultaneously. The two rotating blocks 15 will deflect upward. Under the reset action of each spring 22, the two T-shaped clamping plates 12 will move to the initial position. During the upward movement of the extrusion rod 19, its upper end will gradually penetrate the through hole and abut against the surface of the bearing plate 5 and move upward. The bearing plate 5 will rotate relative to the support base 13. After the bearing plate 5 deflects upward, the workpiece above the bearing plate 5 will slide downward under the action of gravity, and pass through the opening and automatically fall into the interior of the storage basket 16 for collection. There is no need for manual removal of the processed workpiece, the operation is relatively fast and convenient, the continuity of the operation is good, and the removal efficiency of the workpiece is high, which is beneficial to the use of the drilling device.

[0034] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "attachment", "fixation" and the like shall be understood in a broad sense.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
