Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a high-precision CNC machine tool capable of dual-station machining. Background Technology

[0002] Machine tools are machines used to manufacture machinery and equipment. They play a vital role in the modernization of the national economy. The rudiments of machine tools emerged in the 15th century due to the needs of clockmakers and weapons manufacturers, including thread-working lathes, gear-making machines, and water-powered cannon boring machines. Around 1501, the Italian Leonardo da Vinci sketched conceptual designs for lathes, boring machines, thread-working machines, and internal grinding machines, which already included new mechanisms such as cranks, flywheels, centers, and bearings. With the invention of the electric motor, machine tools initially adopted centralized electric motor drives, and later widely adopted individual electric motor drives. Also known as machine tools or machine-working machines, they are commonly referred to simply as machine tools and are generally classified into metal-cutting machine tools, forging and pressing machine tools, and woodworking machine tools. Modern mechanical manufacturing employs many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, and extrusion. However, parts requiring high precision and fine surface roughness generally require final machining on machine tools using cutting methods.

[0003] Currently used CNC machine tools have poor flexibility during processing. They cannot flexibly adjust the processing position according to processing needs, and a single machine tool can only process a single position, resulting in low processing efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-precision CNC machine tool capable of dual-station machining, comprising a fixed base and a support frame, wherein the fixed base is mounted on the support frame and fixedly connected to the support frame, and a worktable is fixedly connected to the top of the fixed base, and further comprising...

[0011] Preferably, the equipment mounting base includes a mounting base body, a transverse slide rail fixedly connected to the top of the mounting base body, a magnetic base fixedly connected to the top of the transverse slide rail via an electronic slider, an mounting groove on the top of the magnetic base, a magnetic cavity inside the magnetic base, a fixing ring on the inner wall of the magnetic cavity, an electromagnet fixedly connected to the inner side of the fixing ring, a through hole adapted to the magnetic cavity on the inner wall of the mounting groove, a connecting block slidably connected to the inner wall of the mounting groove, and a limit magnet block slidably connected through and to the side of the connecting block. Installation and replacement are simple and convenient. Furthermore, the magnetic base can be moved by the electronic slider, and the distance between the processing equipment and the workpiece can be controlled by the movement of the magnetic base, facilitating automatic adjustment according to different processing positions.

[0012] Preferably, the bottom of the mounting base body is fixedly connected to the top of the rotating spherical shell, and a processing device is fixedly connected to the top of the connecting block.

[0015] Preferably, the fixed base is mounted on the workbench and fixedly connected to the workbench, and the end of the arc-shaped telescopic rod away from the rotating rod is fixedly connected to the fixed base.

[0016] This invention provides a high-precision CNC machine tool capable of dual-station machining. It offers the following advantages:

[0017] 1. This high-precision CNC machine tool capable of dual-station machining can be used by opening the arc-shaped sliding door on the protective shell, placing the workpiece to be processed inside the fixed device, and then processing the workpiece inside the fixed device through the machining device. The machining device and the fixed device are set inside the protective shell, which can isolate the machining environment from the external environment and prevent the smoke and debris generated during the machining process from causing injury to the workers. At the same time, the arc-shaped sliding door on the protective shell can be opened by simply moving it to the side, which occupies little space and is convenient to open and close.

[0018] 2. This high-precision CNC machine tool capable of dual-station machining is equipped with a machining device. During use, the positioning seats are moved by the electronic slider at the top of the annular slide. Since there are two sets of positioning seats on the annular slide, the two sets of positioning seats can be moved to the two machining positions of the workpiece. Then, the workpiece can be machined by the device on the equipment mounting base. Multiple parts can be machined at the same time, with high machining efficiency. It can also be freely rotated to various sides of the workpiece, with good adjustability.

[0019] 3. This high-precision CNC machine tool capable of dual-station machining can change the angle of the equipment on the mounting base by drawing out the hydraulic oil from the hydraulic cavity through an external hydraulic cylinder. When the hydraulic oil is drawn out, it drives the extrusion piston to contract into the hydraulic cavity. When the end of the extrusion piston disengages from the rotating spherical shell, the rotating spherical shell can rotate on the spherical base, thereby changing the angle of the equipment inside the mounting base. Through the cooperation of the spherical base and the rotating spherical shell, the equipment on the mounting base can rotate in all directions, with a high degree of rotational freedom.

[0020] 4. This high-precision CNC machine tool capable of dual-station machining is equipped with a mounting base. When installing the machining equipment, the bottom of the connecting block is inserted into the mounting slot, and the limiting magnet is inserted into the through hole under the attraction of the electromagnet. The machining equipment on the connecting block is fixed by the cooperation of the limiting magnet and the through hole. When it is necessary to change the machining equipment, the electromagnet is controlled to generate the opposite magnetic force, which pushes the limiting magnet out of the through hole, thereby removing the connecting block from the mounting slot. The installation and replacement operations are simple and convenient to use. At the same time, the magnetic base can be moved by the electronic slider, and the distance between the machining equipment and the workpiece can be controlled by the movement of the magnetic base. It is convenient to automatically adjust according to different machining positions and is easy to use.

[0021] 5. This high-precision CNC machine tool capable of dual-station machining is equipped with a fixing device. When it is necessary to fix the workpiece, the workpiece is placed on the fixed base, and then the arc-shaped telescopic rod extends to drive the rotating rod to rotate. The rotating rod drives the extrusion rods at both ends of the extrusion seat to rotate, and the extrusion rods drive the extrusion block to rotate. When the extrusion block contacts the workpiece, the workpiece is clamped. When the workpiece is spherical, since the center of the side of the spherical workpiece is the most prominent, the fixed spherical shell first contacts the center of the side of the workpiece during the rotation of the extrusion seat toward the workpiece, and the spherical workpiece can be clamped by the fixed spherical shell. This device can clamp workpieces of various shapes and has good versatility. Attached Figure Description
