Description

Technical Field

[0001] The invention relates to the technical field of grinding processing, and in particular to a processing device for controlling the overall surface shape and high-precision flatness through local grinding processing. Background Art

[0002] Grinding is a common machining method that mainly uses abrasives for surface cutting to achieve the precision requirements of the workpiece surface. It is usually used for materials with higher hardness and can achieve higher surface finish and dimensional accuracy.

[0003] However, in the existing grinding technology, due to factors such as local thermal deformation when the grinding wheel contacts the workpiece and uneven wear of abrasive particles, it is impossible to perform precise local control on certain areas of the workpiece, especially for the control of complex curved surfaces and tiny details. Due to the wear of the grinding wheel and uneven contact between the workpiece and the grinding wheel, the overall surface shape and accuracy of the workpiece may be affected, especially for larger workpieces. This problem is particularly prominent, and the cost of grinding is high, mainly reflected in the use of abrasives, maintenance of machine tools and equipment, and energy consumption, especially when processing materials with higher hardness.

[0004] Therefore, the present invention proposes a processing device for controlling the overall surface shape and high-precision flatness by local grinding to solve the problems mentioned in the above background technology. Summary of the invention

[0005] The present invention aims to solve the difficulty of local precise control of machining accuracy in the prior art by precisely controlling pressure and grinding parameters, and proposes a machining device for controlling the overall surface shape and high-precision flatness by local grinding.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A processing device for controlling the overall surface shape and high-precision flatness by local grinding, comprising an upper structure, a middle structure and a lower structure, wherein the upper structure comprises a pressure mechanism, a pressure sensor and a push rod, and the pressure mechanism is a hydraulic, pneumatic or electric push rod mode; The middle structure includes an abrasive plate and a grinding disc. The front end of the push rod of the upper structure applies pressure to the abrasive plate of the middle structure. The pressure is controlled by a pressure sensor. The coarseness of the grinding disc can be adjusted to control the grinding speed. The connection between the abrasive plate and the push rod can be adjusted at multiple angles to adapt to the processing of workpieces of different shapes. The lower structure comprises a workbench, and the workbench is used for placing a workpiece for processing, and grinding is performed by controlling the relative movement between the grinding plate and the workpiece.

[0007] Preferably, the pressure mechanism has one or more pressure rods, and the grinding force is controlled by changing the pressure applied locally to the workpiece.

[0008] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes precise pressure application on the local area of ​​the workpiece through a pressure mechanism (hydraulic, pneumatic or electric push rod mode). The hydraulic system is suitable for large-scale control, the pneumatic system is suitable for light load or fast response, and the electric push rod is suitable for fine control. By adjusting the pressure applied, the grinding force can be accurately controlled, thereby performing local precision control without affecting the overall workpiece, overcoming the technical difficulty of achieving local high precision in traditional methods; 2. The middle structure of the equipment of the present invention can effectively control the grinding speed and grinding force by adopting a high-hardness wear-resistant abrasive plate and an adjustable abrasive disc, ensure the stable contact between the abrasive and the workpiece, and avoid the problem of uneven pressure during the grinding process. Multiple push rods apply pressure at the same time, which effectively avoids pressure fluctuations, thereby improving the flatness of the overall surface shape and ensuring high-precision flatness and surface shape control. This control method makes the control of processing accuracy in local areas more stable and ensures that the overall surface shape of the workpiece will not be affected; 3. The function of the pressure sensor of the present invention is to ensure that the pressure during the grinding process is maintained within a predetermined range, and can be dynamically adjusted as needed to avoid processing errors caused by pressure fluctuations. This system effectively solves the problem of uneven grinding on the workpiece surface due to unstable pressure in the traditional grinding process. The abrasive plate and grinding disc design in the middle structure have multi-angle adjustment functions, which can adapt to the processing needs of workpieces of different shapes.

[0009] In summary, the present invention fine-tunes and controls various factors in the grinding process. The equipment effectively solves the problem that local areas cannot be accurately controlled in traditional grinding. By accurately controlling local pressure, grinding force and pressure stability, the design significantly improves the overall surface shape and high-precision flatness of the workpiece, and can meet the high-requirement processing of complex workpieces. These advantages make it have broad application potential in the fields of high-precision manufacturing and precision workpiece processing. BRIEF DESCRIPTION OF THE DRAWINGS

The push rod has high hardness and wear resistance and can be adjusted at multiple angles to meet the processing requirements of workpieces of different shapes and ensure stable contact between the abrasive and the workpiece. The front end of the push rod applies pressure to the middle abrasive plate. The push rod drives the grinding process by applying pressure. Multiple push rods can achieve uniform pressure to avoid uneven pressure affecting the processing quality and promote the progress of the grinding process. The pressure is controlled by a pressure sensor, which monitors the pressure applied to the abrasive plate in real time, monitors and adjusts the pressure in real time to ensure the pressure stability during the grinding process and prevents processing errors caused by pressure fluctuations to ensure that the pressure during the processing is kept within a predetermined range.
