Description

Technical Field

[0001] This utility model relates to the field of rocker arm mechanical structure and transmission technology, and in particular to rocker arm hydraulic clamps. Background Technology

[0002] In the field of modern machining and manufacturing, there are extremely high requirements for the machining accuracy and production efficiency of various parts. As an important tooling device, the rocker arm hydraulic clamp is widely used in various machining processes such as turning, milling, planing, and grinding. It is mainly used for the rapid, accurate, and stable positioning and clamping of workpieces (i.e., clamped objects), ensuring that the workpiece position is fixed during machining and is not affected by external forces, thereby guaranteeing machining accuracy and improving production efficiency. With the continuous development of the manufacturing industry and the increasing diversification and complexity of products, traditional clamps can no longer meet the needs of efficient and precise machining. Therefore, the development of new rocker arm hydraulic clamps is urgently needed to adapt to the development trend of modern manufacturing processes.

[0003] Existing fixtures often employ screw-nut clamping mechanisms to fix workpieces. This mechanism mainly consists of a screw, a nut, and clamping blocks that directly contact the workpiece. Its working principle is that rotating the nut causes it to move axially along the screw, which in turn moves the clamping blocks closer to or away from the workpiece, thus clamping and releasing it. For example, in milling, the workpiece is placed on the worktable, its position is adjusted, and the nut is manually rotated to gradually press the clamping blocks against the workpiece. To ensure the stability of the workpiece in all directions, multiple such clamping mechanisms are usually arranged on multiple sides of the workpiece. In addition, some fixtures utilize the principle of wedge blocks for clamping. By pushing the wedge block, the component force generated by its inclined surface pushes the workpiece against the positioning surface and clamps it. These traditional fixtures have relatively simple structures and low costs, but they have certain limitations in terms of ease of operation and clamping stability.

[0004] Existing clamps struggle to achieve rapid and stable fixation when pressing down on the workpiece. The manual rotation of the screw nut or the pushing of the wedge block is cumbersome, time-consuming, and impacts production efficiency. Furthermore, manual operation makes it difficult to ensure uniform and stable pressure each time, easily leading to slight displacement of the workpiece during processing and affecting machining accuracy. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rocker arm hydraulic clamp, which aims to improve the problem that existing clamps are difficult to achieve a fast and stable fixing effect when pressing down to fix the clamped object.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rocker arm hydraulic clamp, including an oil circuit board, a pressing component disposed above the oil circuit board, and a fixing component disposed above the oil circuit board;

[0007] The pressing assembly includes a pressure plate, which is positioned above the oil circuit board. A second rotating shaft is rotatably connected to the inner wall of the pressure plate. A gasket is fixedly connected to the outer wall of the second rotating shaft. A connecting rod is fixedly connected to the outer wall of the second rotating shaft. A third rotating shaft is rotatably connected to the inner wall of the connecting rod. A cylinder is fixedly connected to the outer wall of the third rotating shaft. A first rotating shaft is rotatably connected to the output end of the cylinder. The outer wall of the first rotating shaft is rotatably connected to the inner wall of the pressure plate.

[0008] Furthermore, the fixing component includes a fixing device, which is disposed above the oil circuit board. A fixing seat is fixedly connected to the outer wall of the fixing device, a hydraulic cylinder is slidably connected to the inner wall of the fixing device, a fixing head block is fixedly connected to the outer wall of the fixing device, and a fixing rod is slidably connected to the inner wall of the fixing head block.

[0009] Furthermore, a placement seat is fixedly connected to the upper surface of the oil circuit board, and a bottom fixing point is fixedly connected to the inner wall of the placement seat, with an object attached to one end of the bottom fixing point.

[0010] Furthermore, a side abutment is fixedly connected to the upper surface of the oil circuit board, and the lower surface of the fixing seat is fixedly connected to the upper surface of the oil circuit board.

[0011] Furthermore, the inner wall of the fixing device is slidably connected to the outer wall of the fixing rod, and an object is provided on the outer wall of the fixing head block.

[0012] Furthermore, the lower surface of the cylinder is fixedly connected to the upper surface of the oil circuit board, and the outer wall of the pressure plate is attached to the cylinder output end.

[0013] Furthermore, the outer wall of the pressure plate is attached to the inner wall of the connecting rod, and the outer wall of the cylinder is attached to the inner wall of the connecting rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when using the rocker arm hydraulic clamp to press down and fix the clamped object, the cylinder is started, the cylinder generates thrust, which pushes the pressure plate through the first rotating shaft. The pressure plate rotates on the connecting rod with the second rotating shaft as the fulcrum. One end of the connecting rod rotates under the fixation of the cylinder by the third rotating shaft. In this coordinated operation, the pressure plate presses down and firmly fixes the clamped object, ensuring its stability.

[0024] 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.

[0025] Reference Figure 1 - Figure 3 An embodiment of the present invention provides a rocker arm hydraulic clamp, including an oil circuit board 1, a pressing component is provided above the oil circuit board 1, and a fixing component is provided above the oil circuit board 1;

[0026] The pressing assembly includes a pressure plate 7. Driven by the cylinder 4, the pressure plate 7 rotates around a second rotating shaft 15 as a fulcrum, pressing down on the object 2 to maintain its positional stability during processing. The pressure plate 7 is positioned above the oil circuit plate 1. The inner wall of the pressure plate 7 is rotatably connected to the second rotating shaft 15, which is fixed to the connecting rod 10, providing a fulcrum for the rotation of the pressure plate 7 and ensuring its stability and accuracy. A gasket 9 is fixedly connected to the outer wall of the second rotating shaft 15, and the connecting rod 10 is also fixedly connected to the outer wall of the second rotating shaft 15. The connecting rod 10 supports the second rotating shaft 15 and guides the movement trajectory of the pressure plate 7. Through its own rotational connection to a third rotating shaft 16 at one end, it works in conjunction with the cylinder 4 and the pressure plate 7 to press down on the object 2. The connecting rod 10 is rotatably connected to a shaft 16 on its inner wall. The shaft 16 connects the connecting rod 10 to the cylinder 4, allowing the connecting rod 10 to rotate around it, thereby assisting the pressure plate 7 in completing the pressing action. The shaft 16 is fixedly connected to a cylinder 4 on its outer wall. The cylinder 4, as a power source, generates thrust through the movement of its internal piston, driving the pressure plate 7 to achieve the pressing and fixing action on the object 2. At the same time, the shaft 16 is fixed to provide stable support for the rotation of the connecting rod 10. The output end of the cylinder 4 is rotatably connected to a shaft 8, which connects the cylinder 4 to the pressure plate 7, ensuring that the power of the cylinder 4 can be stably transmitted to the pressure plate 7 to realize the movement of the pressure plate 7. The shaft 8 is rotatably connected to the inner wall of the pressure plate 7 on its outer wall.

[0027] Reference Figure 1 - Figure 5The fixing assembly includes a fixing device 11, which has an internal oil tank to receive oil from the fixing seat 3. The oil pressure compresses the hydraulic cylinder 12, thereby pushing the fixing rod 13 to further fix the object 2. The fixing device 11 is positioned above the oil circuit board 1, which acts as the hydraulic system's oil distribution hub, supplying oil to the fixing seat 3 according to preset requirements, controlling the oil flow and pressure to ensure the smooth execution of the further fixing action. The fixing seat 3 is fixedly connected to the outer wall of the fixing device 11. The fixing seat 3 receives the oil supplied by the oil circuit board 1 and transmits it to the fixing device 11, serving as an oil transfer and distribution intermediary. The hydraulic cylinder 12 is slidably connected to the inner wall of the fixing device 11. The hydraulic cylinder 12 extends outward under oil pressure, converting hydraulic energy into mechanical energy to drive the fixing rod 13. A fixing head block 14 is fixedly connected to the outer wall of the fixing device 11, guiding the movement of the fixing rod 13 and ensuring its smooth movement along a predetermined straight line. The movement ensures the accuracy and stability of fixing object 2. A fixing rod 13 is slidably connected to the inner wall of the fixing head block 14. Under the push of the hydraulic cylinder 12, the fixing rod 13 moves guided by the fixing head block 14, contacting and further fixing object 2, enhancing the stability of object 2 during processing. A placement seat 6 is fixedly connected to the upper surface of the oil circuit plate 1. A bottom fixing point 17 is fixedly connected to the inner wall of the placement seat 6. One end of the bottom fixing point 17 is attached to object 2. Object 2 serves as the rocker arm hydraulic clamp. The object, namely the object 2 that needs to be fixed for subsequent processing, has a side abutment 5 fixedly connected to the upper surface of the oil circuit plate 1, the lower surface of the fixing seat 3 fixedly connected to the upper surface of the oil circuit plate 1, the inner wall of the fixing device 11 slidably connected to the outer wall of the fixing rod 13, the outer wall of the fixing head block 14 is provided with the object 2, the lower surface of the cylinder 4 is fixedly connected to the upper surface of the oil circuit plate 1, the outer wall of the pressure plate 7 is attached to the output end of the cylinder 4, the outer wall of the pressure plate 7 is attached to the inner wall of the connecting rod 10, and the outer wall of the cylinder 4 is attached to the inner wall of the connecting rod 10.

[0028] Working principle: When using the rocker arm hydraulic clamp, when it is necessary to press down and fix the object 2, the cylinder 4 is activated to push the pressure plate 7 to move. The pressure plate 7 is connected to the cylinder 4 through the first rotating shaft 8. The pressure plate 7 rotates on the second rotating shaft 15. The second rotating shaft 15 is fixed on the connecting rod 10 for fixed rotation. One end of the connecting rod 10 rotates through the third rotating shaft 16. The third rotating shaft 16 is fixed by the cylinder 4, thereby realizing the pressing down and fixing of the object 2.

[0029] In addition, after object 2 is placed, oil circuit board 1 will supply oil to fixed seat 3, and fixed seat 3 will supply oil to fixed device 11 at the same time. Both fixed device 11 and fixed seat 3 have oil grooves inside. The oil inside fixed device 11 will squeeze hydraulic cylinder 12 outward. When hydraulic cylinder 12 is squeezed, it will push fixed rod 13. Fixed rod 13 will move through fixed head block 14 to further fix object 2 after fixed rod 13 moves.
