[0017] Reference Figure 1-3 As shown, the utility model provides a technical solution: a high-precision and high-output mechanism, including an upper punch motor base 2, a customized motor 1 and a linear guide rail 11.

[0018] The following is a detailed description of its overall specific settings and functions.

[0019] In this embodiment: a bearing seat 10 is fixedly installed on the inner side of the upper punch motor seat 2, the customized motor 1 is fixed on the upper punch motor seat 2, and an upper punch force sleeve 3 is detachably installed on the surface of the upper punch motor seat 2, and the upper punch force sleeve 3 is slidably connected to the outer side of the linear guide rail 11, and a screw body 13 is fixedly installed on the output end of the customized motor 1, and an upper punch force shaft 4 is installed on the inner side of the upper punch force sleeve 3, and a slide rail 5 is sleeved on the outer side of the upper punch force shaft 4, and a slider 12 is slidably installed on the outer side of the slide rail 5, and a screw flange 9 is installed on the inner side of the upper punch force shaft 4, and the screw body 13 is installed on the inner side of the screw flange 9.

[0020] Specifically, a screw shaft extension block 6 is sleeved on the outside of the screw shaft, a pressure gauge fixing plate 7 is installed on the surface of the screw shaft extension block 6, the pressure gauge fixing plate 7 and the screw shaft extension block 6 are fixedly connected, and an output shaft body 8 is fixedly installed on the surface of the pressure gauge fixing plate 7, and the output shaft body 8 is located on the outside of the screw body 13.

[0021] Working principle: first, the upper punch motor seat 2 and the upper punch output sleeve 3 will be assembled separately, and then they will be precision-made after assembly. The upper punch output shaft 4 and the slide rail 5 will also be assembled separately, and then they will be precision-processed in the CNC machining center. This series of operations are to ensure the accuracy of each component, thereby laying a solid foundation for the stable operation of the entire mechanism. In terms of component fixation, the bearing seat 10 is firmly fixed on the upper punch motor seat 2, and the customized motor 1 is also fixed on the upper punch motor seat 2, and the linear guide 11 will be firmly fixed on the linear guide 11 fixing seat. Next, the screw flange 9, the pressure gauge fixing plate 7 and the output shaft will be fixed together, and they will cooperate with the screw to produce movement. It is worth mentioning that the screw plays an important role here. It is directly fixed inside the customized motor 1 as a rotor. This design is clever. The use of couplings is cleverly reduced, thereby effectively reducing the loss of motor power. The direct benefit of this change is that the output of the customized motor 1 and the screw is greatly increased. When the customized motor 1 starts, the rotor screw body 13 begins to rotate, which will drive the screw flange 9 to run vertically along the linear guide 11. The linear guides 11 on all sides play a key role. They strictly limit the movement direction of the screw flange 9. It is such precise restrictions that ensure the accuracy of the output shaft. Compared with the previous linear bearing and copper sleeve design, the design of this mechanism has significant advantages. It is not only more precise and can meet more stringent working requirements, but also has a more compact structure, saves space, and improves the overall performance and stability of the equipment. This innovative design concept and exquisite craftsmanship have undoubtedly brought new vitality and possibilities to the development of the mechanical field.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
