Technical Field

[0001] This invention relates to the field of machining technology, specifically a drilling and tapping fixture. Background Technology

[0002] Drilling machines are a general term for mechanical equipment that uses a tool that is harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. Tapping machines are a type of mechanical processing equipment that processes internal threads, screws, and threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, or flanges with different specifications of through holes or blind holes.

[0003] In existing drill-tapping machines on the market, the distance to the threaded hole is measured first. After measurement, the metal plate is held down manually before the machine is opened to drill. This results in instability when drilling larger metal plates and difficulty in holding down smaller metal plates, affecting efficiency. Therefore, those skilled in the art have provided a drill-tapping fixture to solve the problems mentioned in the background. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-6 In this embodiment of the invention, a drilling and tapping fixture is provided. A pad 2 is fixedly connected to the front of a drilling and tapping integrated machine 1. A fixing post 3 is slidably connected to the upper surface of the pad 2. A groove 4 is formed on the upper surface of the pad 2. A slider 5 is slidably connected to the inner wall of the groove 4. A fixing block 6 is fixedly connected to the upper surface of the slider 5. A support plate 7 is fixedly connected to the upper surface of the fixing block 6. A first rotating shaft 8 is rotatably connected to the front of the support plate 7. A pushing mechanism 9 is fixedly connected to the surface of the first rotating shaft 8. A first rocker arm 17 is fixedly connected to the front of the first rotating shaft 8. The fixed column 3 has a gear groove 10 inside. The side of the pushing mechanism 9 is fixedly connected to a clamping block 11, and the side of the clamping block 11 is fixedly connected to a clamping mechanism 12. By setting the drilling and tapping machine 1, threaded holes can be drilled for iron plates. By setting the sliding groove 4 and the slider 5, the fixed block 6 can slide. By setting the pushing mechanism 9, the clamping block 11 can be moved. By setting the clamping mechanism 12, the iron plate can be clamped. By setting the fixed column 3, it can move on the pad 2, so that the drilling and tapping clamp can adapt to iron plates of different sizes.

[0025] The pushing mechanism 9 includes a pushing gear 901 fixedly connected to the surface of the first rotating shaft 8. A straight plate 902 is slidably connected to the side of the fixed column 3. A rack 903 is fixedly connected to the lower surface of the straight plate 902. The rack 903 meshes with the pushing gear 901. By setting the pushing gear 901 and the rack 903, the straight plate 902 can be pushed. The clamping mechanism 12 includes a first clamping plate 1201 fixedly connected to the side of the clamping block 11. A clamping groove is opened on the side of the clamping block 11. A sliding block 1202 is slidably connected to the inner wall of the clamping groove. The side of the sliding block 1202 is fixed. A second clamping plate 1203 is connected to the sliding block 1202, and a spiral hole is vertically opened on the upper part of the sliding block 1202. A threaded rod 1204 is threadedly connected to the inner wall of the spiral hole. By setting the threaded rod 1204, the sliding block 1202 can be driven to move downward. A second rotating shaft 13 is rotatably connected to the inner wall of the gear groove 10. A rotating gear 14 is fixedly connected to the surface of the second rotating shaft 13. The rotating gear 14 meshes with the rack 903. The straight plate 902 is slidably connected to the side of the fixed column 3 through the rotating gear 14. By setting the rotating gear 14, the straight plate 902 can slide on the side of the fixed column 3.

[0026] The fixing block 6 is fixedly connected to a connecting plate 15 on its side. The side of the connecting plate 15 is fixedly connected to the side of the fixing post 3. By setting the connecting plate 15, the fixing block 6 can be moved. The upper surface of the clamping block 11 has a round hole. The surface of the threaded rod 1204 is slidably connected to the inner wall of the round hole. The top of the threaded rod 1204 is fixedly connected to a second rocker arm 16. By setting the second rocker arm 16, the threaded rod 1204 can be rotated. The threaded rod 1204 drives the sliding block 1202 to move up and down through the threaded structure, thereby realizing the clamping of the iron plate by the second clamping plate 1203 and the first clamping plate 1201. There are four fixing posts 3. Every two fixing posts 3 form a group, and the two groups of fixing posts 3 are respectively set on both sides of the upper surface of the pad 2. By setting four fixing posts 3, it is easier to adapt to the iron plate and make the iron plate more stable when being drilled.

[0027] The threaded rod 1204 includes a smooth rod 12041 and a clamping spring 12042 spirally wound around the smooth rod 12041. Both ends of the clamping spring 12042 are inserted into the insertion holes at both ends of the smooth rod 12041, thus fixing the clamping spring 12042 and achieving relative stability of its position on the smooth rod 12041. The spiral hole on the sliding block 1202 matches the clamping spring 12042 in its natural state. By acting as the threads of a traditional bolt, the clamping spring 12042 can also drive the sliding block 1202 to move up and down, achieving clamping of the iron plate. Furthermore, it has an effect that traditional bolts do not have: adjustable clamping force range, because only the two ends of the clamping spring 12042 are fixed to the smooth rod 12041. The middle part of the clamping spring 12042 can be stretched and deformed. Therefore, when the sliding block 1202 contacts the iron plate, if the smooth rod 12041 is rotated further, the clamping spring 12042 located below the sliding block 1202 will be stretched, and the sliding block 1202 will be subjected to the downward pulling force of the clamping spring 12042. The clamping spring 12042 located above the sliding block 1202 will be compressed, and the sliding block 1202 will be subjected to the downward pushing force of the clamping spring 12042. For each clockwise rotation of the smooth rod 12041, the force exerted by the clamping spring 12042 on the sliding block 1202 will increase. Conversely, for each counterclockwise rotation of the smooth rod 12041, the force exerted by the clamping spring 12042 on the sliding block 1202 will decrease. This allows for range-based adjustment of the clamping force of the sliding block 1202 on the iron plate.

[0028] On the other hand, traditional bolts are clamped using threaded clamps. Because the bolts are repeatedly rotated, they wear out quickly over time, easily leading to insufficient clamping force. Furthermore, tightening the bolts requires a sufficient number of turns with a wrench, making operation inconvenient. This invention uses a clamping spring 12042 instead of threads. The clamping spring 12042 has a larger structure, resulting in a longer maintenance cycle even with wear. It also features self-adjusting clamping force, ensuring stable and reliable clamping even with wear. Regarding the ease of operation when clamping the bolt, the larger pitch of the clamping spring 12042 allows for a larger sliding block 1202. The spiral structure of the clamping spring 12042 does not have a self-locking function. When the stop block 12043 is removed from the second rocker arm 16, the clamping spring 12042 rotates and recovers its deformation under the action of the sliding block 1202. Simultaneously, the clamping spring 12042 pushes the sliding block 1202 upwards, quickly releasing the clamp from the iron plate. This method facilitates operation during clamping.

[0029] A stop 12043 is also rotatably mounted on the clamping block 11. The stop 12043 can block the second rocker arm 16. Rotating the stop 12043 can block the second rocker arm 16 and prevent the second rocker arm 16 from rotating in the opposite direction, so as to ensure the clamping of the threaded rod 1204.

[0030] The cross-section of the spiral hole on the sliding block 1202 is rectangular, and the clamping spring 12042 is in contact with three surfaces of the spiral hole. The cross-section of the clamping spring 12042 is circular, and the clamping spring 12042 is in line contact with the three surfaces of the spiral hole. This can reduce the friction between the clamping spring 12042 and the spiral hole, which is beneficial to the deformation recovery of the clamping spring 12042.

[0031] The working principle of this invention is as follows: When the drilling rig is working, the position of the fixing column 3 on the pad 2 is adjusted according to the size of the iron plate. First, according to the width of the iron plate, the fixing column 3 is pushed until the middle position of the iron plate can be clamped by the clamping mechanism 12. At the same time, when the fixing column 3 moves, the connecting plate 15 drives the fixing block 6 to move. The movement of the fixing block 6 drives the support plate 7 and the pushing mechanism 9 to move. Then, to adapt to the length of the iron plate, the first rocker arm 17 is rotated. The rotation of the first rocker arm 17 drives the pushing gear 901 to rotate. The pushing gear 901 uses the rack 903 to push the straight plate 902 to move. The straight plate 902 moves, and at this time the gear 100 is rotated. 4. Rotate the straight plate 902, which slides on the side of the fixed column 3 using the rotating gear 14. The straight plate 902 moves and pushes the clamping block 11 to move until it matches the length of the iron plate. At this time, the iron plate is pushed in along the gap between the first clamping plate 1201 and the second clamping plate 1203. Then rotate the second rocker arm 16. The rotation of the second rocker arm 16 drives the threaded rod 1204 to rotate. The rotation of the threaded rod 1204 drives the sliding block 1202 to move down. The movement of the sliding block 1202 drives the second clamping plate 1203 to move down until the first clamping plate 1201 and the second clamping plate 1203 clamp the iron plate, so that the drill and tap clamp can adapt to iron plates of different sizes.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
