Technical Field

[0001] This utility model relates to the field of metal part drilling technology, and in particular to a metal part drilling positioning fixture that is easy to load and unload. Background Technology

[0002] In the machining of metal parts, drilling positioning fixtures play a crucial role. With the increasing scale and precision of the manufacturing industry, the requirements for drilling accuracy and processing efficiency in metal parts are constantly rising. Traditional drilling positioning fixtures are often complex in structure, making it extremely inconvenient to load and unload metal parts. Workers need to spend a lot of time fixing and disassembling parts, which not only reduces the production cycle but also increases labor intensity. Especially when facing multi-variety, small-batch production tasks, frequent changes in part types and cumbersome fixture loading and unloading processes severely restrict the overall production progress. Therefore, a drilling positioning fixture for metal parts that is easy to load and unload is proposed.

[0003] However, traditional tooling has a fixed height during use, and different workers can see the internal metal parts at different positions, requiring workers to bend over or look up to place them, which reduces work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a metal part drilling and positioning fixture that is easy to load and unload. It aims to improve the problem that the height of the metal parts is fixed and different workers can see different positions of the internal metal parts, requiring workers to bend over or look up to place them, which reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling and positioning fixture for easily detachable metal parts, comprising a bottom support, a fixed column rotatably connected to the outer wall of the bottom support, a threaded rod fixedly connected to the outer wall of the fixed column, the outer wall of the threaded rod rotatably connected to the inside of the bottom support, a threaded block threadedly connected to the outer wall of the threaded rod, the lower surface of the threaded block slidably connected to the outer wall of the bottom support, rotating columns rotatably connected to both outer walls of the threaded block, a support rod one fixedly connected to the outer wall of the rotating column, a connecting frame rotatably connected to the outer wall of the support rod one, a through column slidably connected to the inside of the connecting frame, a support rod two rotatably connected to the outer wall of the through column, the outer wall of the support rod two rotatably connected to the outer wall of the bottom support, an operating table fixedly connected to the upper surface of the connecting frame, a drilling mechanism provided on the upper surface of the operating table, and a support assembly provided inside the operating table for supporting other parts.

[0006] Preferably, the support assembly includes a pad, the outer wall of which is fixedly connected to the inner wall of the operating table, and the operating table is rectangular.

[0007] Preferably, a placement plate is fixedly connected to the upper surface of the pad, and a double-headed hydraulic cylinder is fixedly connected to the outer wall of the placement plate.

[0008] Preferably, a baffle is fixedly connected to the output end of the dual-head hydraulic cylinder, and a shaped block is fixedly connected to the outer wall of the baffle.

[0009] Preferably, the irregularly shaped block has a sliding connection to a limiting rod, and the outer wall of the limiting rod is fixedly connected to the outer wall of the placement plate.

[0010] Preferably, the outer wall of the irregular block is fixedly connected to a clamp, and the outer wall of the clamp is slidably connected to the inside of the placement plate.

[0011] Preferably, the outer wall of the irregular block is rotatably connected to a connecting rod, the outer wall of the connecting rod is rotatably connected to a sliding plate, the outer wall of the sliding plate is fixedly connected to a clamp second, and the outer wall of the clamp second is fitted with a mold.

[0012] Preferably, the sliding plate has a second limiting rod inside it, and the outer wall of the second limiting rod is fixedly connected to the outer wall of the placement plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the bottom support is placed on the workbench, and the fixed column is rotated according to the operator's comfort, which drives the threaded rod to rotate inside the support, thereby driving the rotating column, support rod one, and support rod two to move, so that the connecting frame and through column can move, ultimately realizing the height adjustment of the operating table and drilling mechanism, which facilitates operator operation and improves efficiency.

[0015] 2. In this utility model, the mold is placed on the placement plate, and the lower double-headed hydraulic cylinder is activated to pull the two side baffles to move towards each other and center.

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

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a metal parts drilling and positioning fixture that is easy to load and unload, including a bottom support 1. A fixed column 2 is rotatably connected to the outer wall of the bottom support 1. A threaded rod 3 is fixedly connected to the outer wall of the fixed column 2. The outer wall of the threaded rod 3 is rotatably connected to the inside of the bottom support 1. A threaded block 4 is threadedly connected to the outer wall of the threaded rod 3. The lower surface of the threaded block 4 is slidably connected to the outer wall of the bottom support 1. Rotating columns 5 are rotatably connected to both outer walls of the threaded block 4. A support rod 6 is fixedly connected to the outer wall of the rotating column 5. A connecting frame 7 is rotatably connected to the outer wall of the support rod 6. A through column 8 is slidably connected inside the connecting frame 7. A support rod 9 is rotatably connected to the outer wall of the through column 8. The outer wall of the support rod 9 is rotatably connected to the outer wall of the bottom support 1. An operating table 10 is fixedly connected to the upper surface of the connecting frame 7. A drilling mechanism 11 is provided on the upper surface of the operating table 10. A support assembly is provided inside the operating table 10 to support other parts.

[0025] Specifically, the bottom support 1 is placed on the workbench. Based on the worker's comfort level during operation, the fixed column 2 is rotated, causing the threaded rod 3 to rotate inside the bottom support 1. Since the outer wall of the threaded rod 3 is tightly threaded to the threaded block 4, and the lower surface of the threaded block 4 is always in close contact with the bottom support 1, the threaded block 4 can only translate along the outer wall of the bottom support 1 and will not rotate. The movement of the threaded block 4 causes the rotating columns 5 connected to both sides to move, which in turn causes the support rod 6 to move. Because the length of the support rod 6 is fixed and its other end is securely connected to the connecting frame 7, the support rod 6... The rotating column 5 will rotate around the rotation center, causing the support rod 6 to lift the connecting frame 7 upward. The movement of the connecting frame 7 will drive the through column 8 to move, causing the support rod 9 to rotate around the connection point between itself and the bottom support 1. This will cause the through column 8 to slide inside the connecting frame 7, thereby driving the operating table 10 and the drilling mechanism 11 to achieve height adjustment. This allows the height of the operating table 10 to be easily adjusted according to the worker's viewing angle requirements, ensuring that the operating table 10 is always fully within the worker's field of vision. This effectively avoids the worker working with their head down or up for extended periods, improving work efficiency.

[0026] Reference Figure 1 and Figure 3 The support assembly includes a pad 12, the outer wall of which is fixedly connected to the inner wall of the operating table 10, which is rectangular.

[0027] Specifically, the pad 12 provides support for the whole and ensures that the sliding plate 20 and the operating table 10 do not touch the inner wall of the operating table 10 when they move, thus preventing the connecting rod 19 and the sliding plate 20 from being damaged.

[0028] Reference Figure 2 , Figure 4 and Figure 5 A placement plate 13 is fixedly connected to the upper surface of the pad 12, and a double-headed hydraulic cylinder 14 is fixedly connected to the outer wall of the placement plate 13. A baffle 15 is fixedly connected to the output end of the double-headed hydraulic cylinder 14, and a shaped block 16 is fixedly connected to the outer wall of the baffle 15. A limit rod 17 is slidably connected inside the shaped block 16, and the outer wall of the limit rod 17 is fixedly connected to the outer wall of the placement plate 13. A clamp 18 is fixedly connected to the outer wall of the shaped block 16, and the outer wall of the clamp 18 is slidably connected inside the placement plate 13. A connecting rod 19 is rotatably connected to the outer wall of the shaped block 16, and a sliding plate 20 is rotatably connected to the outer wall of the connecting rod 19. A clamp 21 is fixedly connected to the outer wall of the sliding plate 20, and a mold 23 is attached to the outer wall of the clamp 21. A limit rod 22 is slidably connected inside the sliding plate 20, and the outer wall of the limit rod 22 is fixedly connected to the outer wall of the placement plate 13.

[0029] Specifically, the mold 23 is placed above the placement plate 13. The double-headed hydraulic cylinder 14 located below is activated to pull the baffles 15 on both sides to move towards each other and center. The displacement of the baffles 15 causes the irregularly shaped block 16 to slide smoothly along the outer wall of the limiting rod 17. The limiting rod 17 ensures that the irregularly shaped block 16 moves in a certain direction and can also effectively prevent it from falling. The movement of the irregularly shaped block 16 will also drive the clamp 18 to move, thereby clamping and limiting the left and right sides of the mold 23. When the irregularly shaped block 16 moves, it will simultaneously drive the connecting rod 19 to rotate, causing the connecting rod to rotate. 19. Pull the sliding plate 20 to slide smoothly along the outer wall of the limiting rod 22. The limiting rod 22 can prevent the sliding plate 20 from falling off, thereby driving the clamp 21 to clamp and limit the front and rear sides of the mold 23. Through the clamp 18 and clamp 21, the mold 23 is tightly clamped and fixed from all sides, so as to achieve the clamping and fixing of the mold 23 from all sides, ensuring that the position of each drill hole is highly accurate, improving the consistency and precision of part processing, shortening the processing cycle of a single part, and improving the overall production efficiency.

[0030] Working principle: When this fixture is needed, first place the bottom support 1 on the workbench. Then, depending on the worker's comfort level, rotate the fixed column 2 to drive the threaded rod 3 to rotate inside the bottom support 1. Since the outer wall of the threaded rod 3 is threadedly connected to the threaded block 4 and the lower surface of the threaded block 4 is in contact with the bottom support 1, the threaded block 4 moves on the outer wall of the bottom support 1 without rotating on its own. The movement of the threaded block 4 drives the rotating columns 5 on both sides to move, which in turn drives the support rod 6 to move. Since the length of the support rod 6 is fixed and the other side is connected to the connecting frame 7, the support rod 6 rotates around the rotating column 5 as the axis, causing the support rod 6 to lift the connecting frame 7. The movement of the connecting frame 7 drives the through column 8 to move. When the through-column 8 is moved, the second support rod 9 connected to it will also rotate around the part where the second support rod 9 is connected to the bottom bracket 1, causing the through-column 8 to slide inside the connecting frame 7. This, in turn, drives the operating table 10 and the drilling mechanism 11 to move. This allows the height of the operating table 10 to be easily adjusted according to the different viewing angles of the workers, so that the operating table 10 can be fully presented in the workers' field of vision, eliminating the need to look down or up for long periods of time, thus improving work efficiency. When the mold 23 is placed above the placement plate 13, the double-headed hydraulic cylinder 14 below is activated. The double-headed hydraulic cylinder 14 pulls the baffles 15 on both sides to move. The movement of the baffles 15 causes the irregular block 16 to move on the outer wall of the limit rod 17, which in turn drives the clamp 18 to move. Limiting rod 17 ensures that the direction of movement of the irregular block 16 is fixed and that it will not fall off. This allows clamping fixture 18 to hold and limit the left and right sides of mold 23. As the irregular block 16 moves, it also drives connecting rod 19 to rotate. The rotation of connecting rod 19 pulls the sliding plate 20 to move against the outer wall of limiting rod 22. Limiting rod 22 ensures that the sliding plate 20 will not fall off and is thus limited. This, in turn, causes clamping fixture 21 to hold the front and rear sides of mold 23. Pad 12 provides overall support and ensures that the sliding plate 20 and connecting rod 19 will not touch the inner wall of the operating table 10 during movement, preventing damage to the connecting rod 19 and sliding plate 20. Drilling mechanism 11 is used to drill holes in mold 23. Fixture 18 and fixture 21 clamp and fix the parts around the perimeter, ensuring that the position of each drilled hole is highly accurate. This improves the consistency and precision of part processing, shortens the processing cycle of individual parts, and increases overall production efficiency. In other words, this fixture not only allows for easy adjustment of the height of the operating table 10 according to the different perspectives of the operator, so that the operating table 10 can be fully presented in the operator's field of vision, eliminating the need to look down or up for long periods of time and improving work efficiency, but also clamps and fixes the mold 23 around the perimeter, ensuring that the position of each drilled hole is highly accurate. This improves the consistency and precision of part processing, shortens the processing cycle of individual parts, and increases overall production efficiency.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
