Description

Technical Field

[0001] The utility model belongs to the field of numerical control manufacturing, and particularly relates to a working platform for automatic centering of a numerical control milling machine. Background Art

[0002] In the field of numerical control manufacturing, especially during the machining process of numerical control milling machines with high-precision requirements, workpiece centering, that is, the accurate positioning and centering of the workpiece on the machine tool workbench, is a basic step to ensure machining quality. Accurate centering not only directly affects the machining accuracy of the final product, but also directly relates to the overall efficiency of the production line and the control of production costs. With the continuous development of the manufacturing industry, the requirements for machining accuracy are increasing day by day. Therefore, the importance of workpiece centering is becoming increasingly prominent.

[0003] However, traditional numerical control milling machines still mainly rely on manual operation for workpiece centering. Although this method can meet the basic machining requirements to a certain extent, its inherent defects are becoming more and more obvious. Especially when processing parts with complex shapes, especially arc-shaped parts, the difficulty of manual centering increases greatly.

[0004] Traditional centering methods usually rely on simple instruments such as dial indicators and micrometers. Although these instruments can provide a certain measurement accuracy, their measurement ranges are often relatively single and cannot meet the measurement requirements of various complex workpieces. Moreover, the operation of these instruments is relatively complex, and workers need to have high professional skills and rich experience. For arc-shaped parts, due to their large curvature changes and complex shapes, it is very difficult for manual operation to ensure accuracy and stability during the centering process.

[0005] In addition, manual operation is inevitably affected by human factors such as the skill level and fatigue degree of workers. Different workers have different operating habits and skill levels, which may lead to differences in centering results. At the same time, long-term work fatigue will also affect the judgment and operation accuracy of workers, thus increasing the uncertainty and error of centering, which is time-consuming and troublesome, and has low accuracy. Especially when processing some parts with small allowances and high precision, the consistency is relatively poor. Summary of the Utility Model

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0027] This utility model provides a working platform for automatic centering of a CNC milling machine, as Figure 1As shown in the figure, it includes a platform 1; several control modules are arranged around the platform 1; the control modules are respectively connected to several limit blocks 3. The platform 1 serves as the basis of the entire device and is made of high-strength and high-rigidity materials to ensure the stability and reliability of the entire working platform. A magnetic chuck is provided at the bottom of the platform 1, and the working platform 1 is fixed on a CNC milling machine or other equipment through magnetic force to ensure the stability and reliability of the platform 1 during the processing. The control module includes a cylinder 2 and a control system connected to the cylinder 2; the cylinder 2 is installed on the platform 1 and serves as a power source. The cylinder 2 uses high-precision and high-reliability pneumatic components to ensure stable output force and accurate displacement control during the telescopic movement; the limit block 3 is connected to the cylinder 2, and the limit block 3 is a detachable device. Different limit blocks 3 are selected according to the shape of different workpieces, and the shape of the limit block 3 is not limited; and the position of the limit block 3 is adjusted horizontally or vertically according to actual needs. The cylinder 2 and the limit block 3 are connected by a rod. When the cylinder 2 works, it pushes the rod, and the rod then pushes the movement of the limit block 3. Through the telescopic movement of the cylinder 2, the position of the limit block 3 is adjusted, so that the limit block 3 reaches a suitable position. As Figure 2 and Figure 3 shown, the shape of one side of the limit block 3 can be arc-shaped or rectangular, and can be specifically adjusted according to the shape of the workpiece; the limit block 3 is a detachable device, and its shape and quantity can be adjusted according to the requirements of the workpiece; the cylinder 2 is connected to the control system, and a programmable logic controller (PLC) can be used as the control system to control the telescopic movement of the cylinder through programming. At the same time, the PLC can also adjust parameters according to actual needs to meet the processing requirements of different workpieces. The control system also has a fault diagnosis and alarm function. Once an abnormal situation occurs, it can issue an alarm in time and display the fault information, which is convenient for the operator to check and handle. The control module can also be a servo motor.

[0028] To further improve the stability and accuracy of the working platform, T-shaped grooves and inverted sliding grooves are provided on platform 1. The limiting block 3 is partially embedded inside the T-shaped grooves and inverted sliding grooves. The T-shaped grooves and inverted sliding grooves can limit the movement of the limiting block and prevent it from slipping. Specifically, guide rails 5 are provided on both the limiting grooves and inverted sliding grooves. The T-shaped grooves are used to install the guide rails 5 to provide an accurate sliding track for the limiting block 3; the inverted sliding grooves are used to limit the movement range of the guide rails 5 to prevent them from shifting or falling off during the sliding process. A limiting groove 4 is also provided at the bottom of platform 1 and is used in conjunction with the guide rails 5 to limit the movement range of the guide rails 5 and ensure the stability and safety of the entire working platform 1. The several limiting blocks 3 enclose a cavity structure; the cavity structure is used to place workpieces. This working platform encloses a cavity structure through several limiting blocks 3, and this cavity structure is used to place the workpieces to be processed. This design enables the workpieces to be firmly fixed on the platform, avoiding displacement and deformation during the processing. At the same time, the size and shape of the cavity structure are adapted to the shape and size of the limiting blocks 3 and can be adjusted according to the size and shape of the workpieces to meet the processing requirements of different workpieces.

[0029] In practical applications, the operator only needs to place the workpiece in the cavity structure formed by the limiting blocks 3 and set the corresponding processing parameters. Then start the automatic centering function, and the control module drives the limiting blocks 3 to adjust their positions. Through the telescopic movement of the cylinder 2, the rod is pushed and then the limiting block 3 is pushed to move until the preset processing position is reached; at this time, the CNC milling machine can start the processing operation. During the entire processing process, the control system monitors the processing status in real time and adjusts the movement parameters of the cylinder 2 to maintain the stable position and processing accuracy of the workpiece. It is also possible to push the limiting block 3 to move to the specified position by a servo motor, and the servo motor automatically adjusts the movement parameters to maintain the stable position and processing accuracy of the workpiece.

[0030] By using the automatic centering working platform of the CNC milling machine of the present utility model, the processing efficiency and processing accuracy can be greatly improved. Due to the adoption of the automatic centering function, the number of times and time of manual adjustment are reduced, and the processing error is reduced; at the same time, due to the adoption of high-precision and high-reliability pneumatic components and control systems, the stability and reliability of the entire working platform are ensured.

[0031] The automatic centering working platform of the CNC milling machine of the present utility model realizes the automatic centering function through the coordinated use of components such as the control module, the limiting block 3, the T-shaped grooves and the inverted sliding grooves.
