Technical Field
[0001] This utility model relates to the field of machining technology, specifically to a workpiece fixing device for milling, turning, grinding, and drilling equipment. Background Technology
[0002] In milling, turning, grinding, and drilling equipment, the workpiece fixing device is crucial. Existing devices often suffer from unstable clamping and low positioning accuracy due to structural design limitations. During machining, the workpiece is prone to displacement or vibration, affecting machining quality and efficiency. Furthermore, some devices have poor versatility, making it difficult to adapt to different workpiece specifications. Changing and adjusting them is cumbersome, making it difficult to meet the needs of multi-variety, high-precision machining. There is an urgent need to optimize the structure to improve stability, positioning accuracy, and applicability.
[0003] According to a patent application published on the internet (authorization announcement number: CN217965921U), "This utility model relates to the technical field of turning, milling, grinding, and drilling equipment, and in particular to a workpiece fixing device for turning, milling, grinding, and drilling equipment. It includes a mounting box, with an operating table fixedly mounted on the top of the mounting box. A fixing mechanism is installed on the inner side of the operating table to fix the workpiece; a processing mechanism is installed on the outer side of the operating table to perform grinding processing on the workpiece. A dust extraction hole is provided on the operating table, and an exhaust fan is fixedly installed inside the mounting box, with the exhaust fan inlet located directly below the dust extraction hole. This utility model can stably fix the workpiece, greatly improving the stability of workpiece processing."

Different processing steps can be achieved by installing different tools on the mounting base 58, which improves the continuity and multi-functionality of processing. The servo motor 53 drives the screw 52 to rotate, which drives the slide 55 to move up and down inside the fixed frame 51, so that the milling cutter 59 and the grinding disc 501 can accurately reach the processing position, ensuring processing accuracy. When used in conjunction with the telescopic frame 56, the working range of the processing mechanism is expanded, which can adapt to the processing needs of workpieces of different sizes.

Then, the hydraulic cylinder 47 drives the hydraulic telescopic column 48 to descend, and the spring column 405 pulls the clamping plate 406 to the top two ends of the workpiece, thereby clamping the workpiece and achieving bidirectional clamping from top to bottom, which improves the stability of the workpiece fixation. The motor 44 drives the first rotating shaft 45 and the fixed frame 46 to rotate, which synchronously drives the top component to rotate. In conjunction with the second rotating shaft 401, the workpiece is rotated, which makes it easier for the processing mechanism 5 to perform turning, milling, grinding, drilling and other operations on the workpiece from different angles, reducing the number of workpiece clamping times and improving processing efficiency. During the processing, there will be no problem of the workpiece loosening or falling off.
[0037] After the workpiece is fixed, it can be processed by the processing mechanism 5. Different processing steps can be achieved by installing different tools on the mounting base 58, which improves the continuity and multi-functionality of processing. The servo motor 53 drives the screw 52 to rotate, which drives the slide 55 to move up and down inside the fixed frame 51, so that the milling cutter 59 and the grinding disc 501 can accurately reach the processing position, ensuring processing accuracy.
