[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] The following is in conjunction with the appendix Figures 1 to 4 The specific embodiments of this utility model will be described in further detail.
[0035] Depend on Figures 1 to 4As shown, this utility model includes a workbench 10. In order to facilitate the control of the drilling angle, a left guard 25 and a right guard are fixedly connected symmetrically on the left and right sides of the front side of the workbench 10. A rotatable rotating seat 11 is provided on the front side of the workbench 10. The left and right sides of the rotating seat 11 are rotatably connected to the left guard 25 and the right guard, respectively. A cylinder 5 for providing power for rotating the rotating seat 11 is rotatably connected to the lower side of the workbench 10. The moving end of the cylinder 5 is connected to the bottom of the rotating seat 11. A limiting mechanism for limiting the rotation angle of the rotating seat 11 is provided on the front side of the rotating seat 11.
[0036] It should be noted that a multi-drill machine refers to a drilling machine with multiple drill bits that can work together to create holes. These machines come in single-row, three-row, and six-row configurations. Also known as a brush drill machine, a multi-drill machine converts the traditional manual drilling action into a mechanical action, which is completed automatically. Depending on the application, the angle of the drill bit needs to be adjusted to create holes at different angles on the material.
[0037] In this embodiment, the workbench 10 is used to place and fix the plate, and the workbench 10 is provided with a fixing mechanism for fixing the plate; multiple drill bits and a sliding mechanism that can drive the multiple drill bits to slide relative to the rotating seat 11 can be installed on the side of the rotating seat 11 near the workbench 10, so as to perform drilling operations on the plate through multiple drill bits; this application mainly protects the angle control mechanism, so the fixing mechanism and sliding mechanism will not be described in detail.
[0038] In use, the fixed end of the cylinder 5 is rotatably connected to the bottom of the worktable 10, and the moving end of the cylinder 5 is rotatably connected to the bottom of the rotating seat 11. After the cylinder 5 is started, it will drive the rotating seat 11 to rotate relative to the worktable 10. Under the action of the limiting mechanism, the maximum angle of rotation of the rotating seat 11 relative to the worktable 10 can be limited.
[0039] Furthermore, by Figures 1 to 4 As shown, to facilitate the installation of cylinder 5 by the workers, a front cover plate 2 is fixedly connected to the lower side of the workbench 10, a connecting shaft 1 is fixedly connected to the middle of the front cover plate 2, a base 3 is fixedly connected to the bottom of the fixed end of cylinder 5, and the lower side of the base 3 is fitted onto the outside of the connecting shaft 1. Cylinder 5 is rotatably connected to the connecting shaft 1 through the base 3. A limiting bolt 4 is provided on each of the left and right sides of the base 3 and threadedly connected to the connecting shaft 1. A fixing block 7 is fixedly connected to the bottom of the rotating seat 11, and a fisheye connector 6 is rotatably connected to the side of the fixing block 7. The output end of cylinder 5 is fixedly connected to the fisheye connector 6. A through hole is opened in the middle of the base 3 for fitting onto the outside of the connecting shaft 1. The fisheye connector 6 is existing technology, such as the FJ11 series fisheye connector 6. The specific model can be determined according to actual needs, and will not be described in detail here.
[0040] A rotating shaft 9 is fixedly connected to the side of the left protective cover 25 and the right protective cover near the rotating seat 11. The left and right sides of the rotating seat 11 are rotatably connected to the rotating shaft 9 through self-lubricating bearings 8.
[0041] In use, the through hole in the middle of the base 3 can be passed through the connecting shaft 1. At this time, the left and right positions of the base 3 and the cylinder 5 can be limited by the two limit bolts 4. After the cylinder 5 is started, the output end of the cylinder 5 drives the fixed block 7 to move through the fisheye connector 6, which in turn drives the rotating seat 11 to rotate. When the rotating seat 11 rotates relative to the worktable 10, the rotation process can be made smoother and more stable under the action of the self-lubricating bearing 8.
[0042] Furthermore, by Figures 1 to 4 As shown, to facilitate the adjustment of the drilling angle by the staff, the limiting mechanism includes:
[0043] The first limiting block 12 is rotatably connected to the rotating seat 11 on its right side;
[0044] The second limiting block 23 is rotatably connected to the left protective cover 25 on its left side;
[0045] Angle ruler 14, the first limiting block 12 and the second limiting block 23 each have a through hole in the middle, each through hole is fitted on the outer side of the middle part of the angle ruler 14, a fixing pad 15 is fixedly connected to each of the front and rear ends of the angle ruler 14, an adjustment component is provided at the front of the angle ruler 14 that can slide back and forth relative to the angle ruler 14, the second limiting block 23 is located at the front of the first limiting block 12, and the adjustment component is located at the front of the second limiting block 23;
[0046] Furthermore, by Figures 1 to 4 As shown, in order to increase the service life of the device, a buffer block 17 is provided on the side of the first limiting block 12 away from the second limiting block 23, which is fitted on the outside of the angle ruler 14. A buffer pad 16 is provided on the front and rear sides of the buffer block 17. A plane bearing 24 is provided between the first limiting block 12 and the rotating seat 11 and between the second limiting block 23 and the left protective cover 25.
[0047] In use, between the two fixed pads 15, on the outer side of the angle ruler 14, from back to front, are a buffer block 17, a first limit block 12, a second limit block 23, and an adjustment component. After the cylinder 5 is started, the rotating seat 11 will rotate relative to the worktable 10. At this time, the first limit block 12 and the second limit block will move away from each other. The distance between the buffer block 17 and the adjustment component is the farthest distance that the first limit block 12 and the second limit block 23 can move away from each other. By adjusting the position of the adjustment component on the angle ruler 14, the farthest distance that the first limit block 12 and the second limit block 23 can move away from each other can be adjusted, thereby adjusting the angle at which the rotating seat 11 rotates relative to the worktable 10.
[0048] After cylinder 5 is started, the first limit block 12 will impact the buffer block 17. At this time, under the action of the buffer block 17 and the two buffer pads 16, the impact damage of the first limit block 12 to the fixed pad 15 can be reduced. The buffer block 17 and the buffer pads 16 are both made of rubber. After a period of use, the buffer pads 16 and the buffer block 17 can be replaced.
[0049] When the rotating seat 11 rotates relative to the worktable 10, the plane bearing 24 makes the rotation more stable and reduces the occurrence of jamming.
[0050] Furthermore, by Figures 1 to 4 As shown, for the convenience of the staff, the adjustment assembly includes a fixed sleeve 21, a positioning ring 20 and an adjustment handle 22. The fixed sleeve 21 is fitted on the outside of the angle ruler 14. A placement groove is opened inside the fixed sleeve 21, and the positioning ring 20 is placed in the placement groove. An adjustment screw is fixedly connected to the side of the adjustment handle 22 near the fixed sleeve 21. The middle part of the adjustment screw is threaded to the fixed sleeve 21, and the left side of the adjustment screw passes through the side wall of the fixed sleeve 21 and abuts against the positioning ring 20.
[0051] In use, after adjusting the fixing sleeve 21 to a specific position on the angle ruler 14, the adjusting handle 22 can be rotated. At this time, the adjusting handle 22 drives the adjusting screw to rotate, so that the adjusting screw presses against the positioning ring 20. The position of the fixing sleeve 21 relative to the angle ruler 14 is fixed by the friction between the positioning ring 20 and the angle ruler 14, thus completing the angle adjustment.
[0052] Furthermore, by Figures 1 to 4 As shown, in order to make it easier for staff to see, the outer side of the angle ruler 14 has scale lines.
[0053] During use, the staff can see the position of the adjustment component through the scale lines, making it easy to adjust the maximum rotation angle.
[0054] When using this utility model, the fixed end of the cylinder 5 is first rotatably connected to the bottom of the worktable 10, and the moving end of the cylinder 5 is rotatably connected to the bottom of the rotating seat 11. After the cylinder 5 is started, the rotating seat 11 will rotate relative to the worktable 10. At this time, the first limit block 12 and the second limit block 23 will move away from each other. The distance between the buffer block 17 and the adjustment component is the farthest distance that the first limit block 12 and the second limit block 23 can move away from each other. By adjusting the position of the adjustment component on the angle ruler 14, the farthest distance that the first limit block 12 and the second limit block 23 can move away from each other can be adjusted, thereby adjusting the angle at which the rotating seat 11 rotates relative to the worktable 10, thus completing the angle adjustment.
[0055] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the function of conveniently controlling the drilling angle, making it easier for operators to install cylinder 5, adjust the drilling angle, increase the service life of the device, and facilitate operator operation.
[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
