Description
Technical Field
[0001] This utility model relates to the technical field of drilling equipment, and in particular to a multi-angle positioning fixture for drilling machines. Background Technology
[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. It typically uses the rotation of the drill bit as the main motion, and the axial movement of the drill bit as the feed motion. Through the high-speed rotation of the drill bit and the downward pressure, the cutting edge of the drill bit cuts into the workpiece, thus forming a hole. When using a drilling machine, a positioning fixture is usually required to fix the workpiece in place.
[0003] Current drilling machines can fix workpieces at the required angle when using fixtures. However, most current fixtures can only lift one side of the workpiece. When both ends of the workpiece need to be drilled at an angle, one end of the workpiece needs to be processed first, and then the workpiece needs to be reinstalled before the other side of the workpiece can be processed. This increases the working limitations of the drilling machine positioning fixture. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-angle positioning fixture for drilling machines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-angle positioning fixture for a drilling machine includes a base. The surface of the base is rotatably connected to two rotating shafts. The middle portions of the two rotating shafts are fixedly connected to corresponding rotating wheels. The two ends of the two rotating shafts are fixedly connected to corresponding first connecting rods. Each first connecting rod is rotatably connected to a corresponding second connecting rod. Each second connecting rod is rotatably connected to a top plate via a bearing. The surface of each rotating wheel abuts against a corresponding pad. Each pad is adhered to the surface of a corresponding abutting plate. Each abutting plate is rotatably connected to a corresponding threaded rod. Each threaded rod is threadedly connected to the base. The end of each threaded rod is fixedly connected to a corresponding knob.
[0006] Preferably, the lower surface of the top plate is rotatably connected to both ends of the double-ended stud by bearings, the double-ended stud is threadedly connected to two clamping plates, and each clamping plate slides through the top plate via a groove.
[0007] Preferably, the surfaces of the two clamping plates are fixedly connected to both ends of the bellows, and the bellows is disposed outside the double-ended stud.
[0008] Preferably, one end of the double-ended stud is fixedly connected to the disc.
[0009] Preferably, each of the said wheels has multiple grips mounted on its surface.
[0010] Preferably, each of the rotating wheels has multiple scales machined on both sides.
[0011] Preferably, both clamping plates have soft pads adhered to their surfaces.
[0012] The beneficial effects of this utility model are as follows: 1. The system comprises a base, shaft, wheel, first connecting rod, second connecting rod, top plate, pad, clamping plate, threaded rod, and knob. When the workpiece being machined by the drilling machine needs to be tilted and fixed, the operator fixes the workpiece on the top plate and then rotates a knob on one side of the base. The knob rotates the threaded rod, which in turn moves the clamping plate. The clamping plate then moves the pad, which moves off the wheel. The operator then holds the handle and rotates the wheel, which in turn rotates the shaft. The shaft rotates the two first connecting rods on one side, which in turn rotate the corresponding second connecting rods. Due to the top plate... The height on the other side is fixed, so the second linkage will push the other side of the top plate to move upward, causing the top plate to tilt. When the top plate drives the workpiece to rotate to a suitable angle, the operator stops rotating the wheel and rotates the knob in the opposite direction. The knob, through the above transmission method, makes the pad press against the wheel, fixing the angle of the wheel. In this way, the workpiece to be processed by the drilling machine can be tilted and fixed, which allows the drilling machine to perform drilling processing on the surface of the workpiece at different angles, and can perform tilted drilling processing on multiple sides of the workpiece without disassembly, thereby reducing the working limitations of the drilling machine positioning fixture. 2. By using the rotating shaft, rotating wheel, first connecting rod, second connecting rod, top plate, pad plate, clamping plate, threaded rod and knob, when it is necessary to adjust the height of the workpiece to make it easier to contact the drill bit, the operator can rotate the two rotating wheels on both sides at the same time in the above manner, so that the height of the top plate can be raised horizontally, which makes it easier for the operator to use the multi-angle positioning fixture of the drilling machine.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example 1, referring to Figures 1 to 5A multi-angle positioning fixture for a drilling machine includes a base 1. The surface of the base 1 is rotatably connected to two rotating shafts 2, which rotate on the base 1. The middle portions of the two rotating shafts 2 are fixedly connected to corresponding rotating wheels 3, which drive the rotating shafts 2 to rotate. The two ends of the two rotating shafts 2 are fixedly connected to corresponding first connecting rods 6, which drive the first connecting rods 6 to rotate. Each first connecting rod 6 is rotatably connected to a corresponding second connecting rod 7, which drives the second connecting rod 7 to rotate. Each second connecting rod 7 is rotatably connected to a top plate 8 via a bearing, and the second connecting rod 7 can move one side of the top plate 8. Each rotating wheel 3... The surfaces are respectively pressed against the corresponding pads 11. The pads 11 can increase the friction between the pressing plate 10 and the rotating wheel 3. The pads 11 are made of metal, which can prevent the rotating wheel 3 from rotating on its own. Each pad 11 is respectively attached to the surface of the corresponding pressing plate 10. Each pressing plate 10 is rotatably connected to the corresponding threaded rod 9. The threaded rod 9 drives the pressing plate 10 to move. Each threaded rod 9 is threadedly connected to the base 1. The threaded rod 9 rotates on the base 1, driving the pressing plate 10 to move. The end of each threaded rod 9 is respectively fixedly connected to the corresponding knob 12. The knob 12 makes it easy for the operator to rotate the threaded rod 9. When it is necessary to tilt and fix the workpiece being processed by the drilling machine, the operator fixes the workpiece on the top plate 8, and then rotates the knob 12 on one side of the base 1. The knob 12 drives the threaded rod 9 to rotate, the threaded rod 9 drives the clamping plate 10 to move, and the clamping plate 10 drives the pad 11 to move. After the pad 11 is removed from the rotating wheel 3, the operator holds the handle 4 and drives the rotating wheel 3 to rotate. The rotating wheel 3 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the two first connecting rods 6 on one side to rotate. The first connecting rods 6 drive the corresponding second connecting rods 7 to rotate. Since the other side of the top plate 8... The height is fixed, so the second link 7 will push the other side of the top plate 8 to move upward, causing the top plate 8 to tilt. When the top plate 8 drives the workpiece to rotate to a suitable angle, the operator stops rotating the rotary wheel 3 and rotates the knob 12 in the opposite direction. The knob 12 causes the pad 11 to press against the rotary wheel 3 through the above transmission method, so that the angle of the rotary wheel 3 is fixed. In this way, the workpiece that the drilling machine needs to process can be tilted and fixed, which allows the drilling machine to drill holes at different angles on the surface of the workpiece, thereby reducing the working limitations of the drilling machine positioning fixture.
[0017] In this embodiment, the lower surface of the top plate 8 is rotatably connected to both ends of the double-ended stud 13 via bearings. The double-ended stud 13 rotates below the top plate 8 and is threadedly connected to two clamping plates 15. The double-ended stud 13 drives the clamping plates 15 to rotate. Each clamping plate 15 slides through the top plate 8 via a groove. The surfaces of the two clamping plates 15 are fixedly connected to both ends of the bellows 16. The bellows 16 can protect the double-ended stud 13 and is located on the outside of the double-ended stud 13. One end of the stud 13 is fixedly connected to the disc 14. The disc 14 facilitates the operator to rotate the double-headed stud 13. Each rotating wheel 3 has multiple handles 4 installed on its surface. The handles 4 facilitate the operator to rotate the rotating wheel 3. Each rotating wheel 3 has multiple scales 5 machined on both sides. The scales 5 make it easier for the operator to know the rotation angle of the rotating wheel 3, and thus make it easier to know the tilt angle of the top plate 8. The surfaces of the two clamping plates 15 are both covered with soft pads 17. The soft pads 17 are made of rubber, which can prevent the clamping plates 15 from damaging the workpiece.
[0018] The working principle of this embodiment is as follows: During use, the operator first places the workpiece to be drilled on the top plate 8, positioning it between the two clamping plates 15. Then, the operator rotates the disc 14, which drives the double-ended stud 13 to rotate. The double-ended stud 13 drives the two clamping plates 15 to move simultaneously. When the soft pads 17 on the surfaces of the two clamping plates 15 are fully pressed against the surface of the workpiece, the operator stops rotating the disc 14. When it is necessary to tilt and fix the workpiece being drilled, the operator rotates the knob 12 on one side of the base 1. The knob 12 drives the threaded rod 9 to rotate, which in turn drives the abutment plate 10 to move. The abutment plate 10 then drives the pad 11 to move. After the pad 11 is removed from the rotating wheel 3, the operator holds the handle 4, which drives the rotating wheel 3 to rotate. The rotating wheel 3 then drives the rotating shaft 2 to rotate. The first connecting rod 6 on one side rotates, and the first connecting rod 6 drives the corresponding second connecting rod 7 to rotate. Since the height of the other side of the top plate 8 is fixed, the second connecting rod 7 will push the other side of the top plate 8 to move upward, causing the top plate 8 to tilt. When the top plate 8 drives the workpiece to rotate to a suitable angle, the operator stops rotating the rotating wheel 3 and rotates the knob 12 in the opposite direction. The knob 12 causes the pad 11 to press against the rotating wheel 3 through the above transmission method, so that the angle of the rotating wheel 3 is fixed. When it is necessary to adjust the height of the workpiece to make it easier to contact the drill bit, the operator can rotate the two rotating wheels 3 on both sides at the same time through the above method, so that the height of the top plate 8 can be raised horizontally. Through the above method, the workpiece can be fixed in various angles, thereby completing the multi-angle positioning of the workpiece.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
