Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a correction mechanism for numerically controlled machine tools. Background Art

[0002] With the rapid development of the manufacturing industry, CNC machine tools, as the core equipment for precision machining, have machining accuracy and stability that are crucial to product quality. However, after long-term operation or being affected by the external environment, the various components of the CNC machine tools may produce slight displacement or deformation, resulting in increased machining errors. Therefore, it is particularly important to develop a CNC machine tool correction mechanism.

[0003] Reference announcement number CN219403304U discloses a calibration mechanism for a CNC machine tool, comprising a platform plate, on which a support frame for supporting a workpiece is mounted, the number of the support frames being two, an electric cylinder for pushing the support frame being mounted at the bottom, a base being mounted on the top of the platform plate, the base being between the two support frames, a laser calibrator being mounted on the base, the electric cylinder being controlled by the laser calibrator, and a laser calibrator being provided to control the lifting and lowering of the support frames to stabilize the support frames of the workpiece at the same horizontal height, and the position of the workpiece is corrected by adjusting the support frames to prevent the position of the workpiece from deviating during processing; a laser sensor switch is provided to control the two support frames to simultaneously maintain an initial height, preventing the support frames from being too high or too low, and automatically adjusting the height of the support frames, saving time for manual adjustment and greatly improving the efficiency of production and processing. As can be seen from the above, although the calibration mechanism can be well applied, it is usually not convenient to block and protect the laser calibrator. When the calibration mechanism is not in use, the laser calibrator is exposed to the external environment and is easily damaged by external forces, thereby shortening the service life of the calibration mechanism and often causing trouble for users.

Both ends of the guide rods extend to the outside of the guide cylinders, and the top of the guide rods is connected to the bottom end of the supporting platform. The setting of the guide rods and the guide cylinders can limit the movement range of the supporting platform.

[0008] Preferably, an infrared transmitter is provided on the upper outer wall of one side of the protective box, and an infrared receiver is provided on the outer wall of the base close to the protective box. The infrared transmitter and the infrared receiver are set to monitor whether the clamp frame is reset to the set initial height.

[0009] Preferably, a clamping frame is provided at the top of the base, and a first clamping plate is installed at the bottom of the clamping frame. The first clamping plate is provided to cooperate with the second clamping plate to clamp and fix the two ends of the workpiece.

[0010] Preferably, the top of the clamp frame is threadedly connected to a threaded rod, the top of the threaded rod extends to the outside of the clamp frame, and the bottom end of the threaded rod is rotatably installed with a second clamping plate, the outer wall of the second clamping plate touches the inner wall of the clamp frame, and the threaded rod is turned to drive the second clamping plate to be raised and lowered.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the CNC machine tool correction mechanism not only effectively protects the integrity of the laser calibrator and extends the service life of the correction mechanism, but also achieves the purpose of automatically correcting the workpiece and ensures the correction effect when the correction mechanism is used;

[0012] (1) The linkage seat is driven to move horizontally by the telescopic driving member, so that the linkage seat drives the rail seat located at the top of the guide rail to slide, so that the linkage seat drives the protective box to move horizontally smoothly through the connecting rod. When the two protective boxes are close to each other, the two protective boxes will shield and protect the laser calibrator to reduce the damage to the laser calibrator exposed to the external environment when the calibration mechanism is not in use, thereby effectively protecting the integrity of the laser calibrator and extending the service life of the calibration mechanism;

[0013] (2) The second clamping plate cooperates with the first clamping plate to clamp and fix the two ends of the workpiece, and the laser calibrator can monitor whether the workpiece is in a horizontal state. If the workpiece is in an inclined state, a corresponding second lifting drive member can drive one end of the workpiece to rise and fall until the workpiece is in a horizontal state, thereby achieving the purpose of automatically calibrating the workpiece;

[0014] (3) The supporting platform is driven to move upward by the first lifting drive member, so that the supporting platform drives the guide rod located inside the guide cylinder to slide upward, so that the supporting platform drives the infrared transmitter on the outer wall of the protective box to move upward smoothly. When the infrared transmitter moves to the set highest position, if the transmission signal is received by the infrared receiver, it means that the clamping component at the top of the base is reset to the original set height. If the infrared receiver does not receive the signal transmitted by the infrared transmitter, the second lifting drive member can drive the infrared receiver on the outer wall of the base to move up and down until the infrared receiver receives a signal indicating that the clamping frame has been reset to the original set height, thereby ensuring the correction effect when the correction mechanism is used.
