Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a composite multi-station ultra-precision CNC machine tool. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] When machining parts on a CNC machine tool, multiple processes are generally required, sequentially performing roughing, semi-finishing, finishing, and final finishing stages. Specifically, processes such as measuring the outer diameter, drilling, or surface machining are performed on the parts. After the parts are fixed on the machine tool, the machine tool's drive device will guide the parts closer to the machining device, and then the machining device will perform multiple processes on the parts sequentially. Although this machining method can ensure the yield of finished parts, the loading and unloading time is relatively long, and the processing efficiency is not high, which needs to be improved. Utility Model Content

[0004] To improve the problem of low parts processing efficiency, this application provides a composite multi-station ultra-precision CNC machine tool.

[0005] The composite multi-station ultra-precision CNC machine tool provided in this application adopts the following technical solution:

[0006] A composite multi-station ultra-precision CNC machine tool includes a machine tool, a mounting base on the machine tool, a rotating seat rotatably connected to the mounting base, a drive assembly on the mounting base, a fixed seat on the rotating seat, and a machining seat on the machine tool. The drive assembly includes a servo motor on the mounting base, a connecting seat fixed to the servo motor, a connecting rod rotatably connected to the connecting seat, and a drive gear fixed to the end of the connecting rod away from the servo motor. A driven gear is fixed to the outer wall of the rotating seat, and the driven gear meshes with the drive gear. The diameter of the drive gear is smaller than the diameter of the driven gear. The servo motor drives the connecting rod to rotate. The fixed seat is used to mount parts, and the machining seat is used to mount machining devices. There are six fixed seats, which are equally spaced along the edge of the rotating seat. There are five machining seats, which are located on the periphery of the rotating seat and are positioned corresponding to the fixed seats.

[0007] By adopting the above technical solution, a servo motor drives the connecting rod to rotate, which in turn drives the drive gear to rotate, thereby driving the driven gear to rotate. The rotation of the driven gear drives the rotating seat to rotate. Since the driven gear and the drive gear mesh and the driven gear is relatively large, and the servo motor has been set to a certain speed, during processing (first aligning the parts with the processing device on the processing seat), the five processing seats process the parts on the five fixed seats respectively. Then the rotating seat rotates, and the six fixed seats on the rotating seat rotate to the next station for processing different processes every 60 degrees. The gear drive makes the rotating seat rotate stably, saving the transfer time before and after processing the parts. Moreover, five of the six parts can be processed simultaneously for different processes. After the rotating seat rotates one revolution, all six parts have completed all processes. The composite multi-station ultra-precision CNC machine tool of this application can shorten the loading and unloading time and improve the processing efficiency of parts.

[0008] Preferably, the mounting base is provided with an auxiliary component, which includes an auxiliary seat fixed to the mounting base, an auxiliary rod rotatably connected to the auxiliary seat, and an auxiliary disk fixed to the end of the auxiliary rod away from the auxiliary seat. The bottom surface of the rotating seat has an auxiliary cavity, the auxiliary rod extends into the auxiliary cavity, and the outer wall of the auxiliary disk abuts against the cavity wall of the auxiliary cavity.

[0009] By adopting the above technical solution and setting auxiliary components to improve the rotational stability of the rotating seat, the fixed seat on the rotating seat will return to the same position of the previous fixed seat every time it rotates one-sixth of a circle, thereby improving the machining accuracy.

[0010] Preferably, the connecting seat has a connecting cavity, and the output shaft of the servo motor and the connecting rod are rotatably connected in the connecting cavity, and the output shaft of the servo motor and the connecting rod are coaxially fixed.

[0011] By adopting the above technical solution, a connecting cavity is set up to accommodate and rotate the connecting rod and the output shaft of the servo motor, thereby improving the stability of the connecting rod during rotation and thus improving the stability of the drive gear and driven gear transmission.

[0012] Preferably, the rotating seat is provided with a positioning seat, and the fixed seat is fixed on the positioning seat.

[0013] By adopting the above technical solution, a positioning seat is set to install and fix the fixed seat. On the one hand, it is convenient to position the fixed seat. After the fixed seat is installed, the distance between adjacent fixed seats is equal, thereby meeting the processing requirements.

[0014] Preferably, the end of the fixed base near the machining base is provided with a three-jaw chuck, which is used to fix the parts.

[0015] By adopting the above technical solution, a three-jaw chuck refers to a machine tool accessory that uses the radial movement of three movable jaws evenly distributed on the chuck body to clamp and position the workpiece, making it convenient to install and remove parts.

[0016] Preferably, the machine tool is provided with a guide seat, the guide seat is provided with a guide rail, the machining seat is provided with a guide groove for the guide rail to be accommodated, the guide seat is slidably connected to the guide seat, and the sliding direction of the machining seat intersects with and is perpendicular to the rotation axis of the rotating seat.

[0017] By adopting the above technical solution, a guide seat is set up and the movement of the machining seat is guided by the cooperation of the guide rail and the guide groove, thereby improving the movement stability of the machining seat and preventing deviation of the machining seat from affecting the machining accuracy of the parts.

[0018] Preferably, the processing base is provided with a processing block, which is used to install the processing device.

[0019] By adopting the above technical solution, a processing block is set up to install and fix processing devices, such as milling cutters, drills, or reamers. According to the processing needs of the parts, the corresponding devices are installed on the processing block to process the parts.

[0020] Preferably, the machine tool is equipped with a robotic arm, which is used to assist in flipping the parts.

[0021] By adopting the above technical solution, a robotic arm is set up to assist in flipping parts, eliminating the need for manual flipping, saving time and improving processing efficiency.

[0022] The main technical effects of this utility model are reflected in the following aspects:

[0023] 1. This utility model can save loading and unloading time and improve the processing efficiency of parts;

[0024] 2. This utility model improves the rotational stability of the rotating seat and enhances machining accuracy by setting auxiliary components;

[0025] 3. This utility model improves the stability of the machining seat by setting guide rails and guide grooves to guide the movement of the machining seat. Attached Figure Description
