Description

Technical Field

[0001] The utility model relates to the technical field of CNC milling machines, in particular to a multi-station CNC milling machine. Background Art

[0002] A CNC milling machine is a machine tool that integrates a digital control system into an ordinary milling machine and can perform milling processing more accurately under the control of program code. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. CNC milling machines with tool magazine are also called machining centers. The basic parts of a CNC milling machine usually refer to structural parts such as the bed, columns, beams, worktables, and bases. They are large in size (commonly known as large parts), and the "well" constitutes the basic framework of the machine tool.

[0003] Among them, the "multi-station CNC milling machine" disclosed by patent announcement number "CN208427984U" has solved the various drawbacks of the existing workpieces, such as the slow processing process, which affects the processing of the workpieces, and the unstable fixation of the workpieces, which greatly reduces the qualified rate of the workpieces. After further searching, it was found that the "high-precision multi-station CNC milling machine" disclosed by patent announcement number "CN215431703U" has effectively solved the problem of repeated flipping, clamping and positioning during the processing process, which causes processing errors and affects the quality of the workpieces through specific technical structure settings. Affects the processing accuracy; and the single-sided milling processing is cumbersome, the work efficiency is low, and it cannot meet people's processing requirements and other technical disadvantages. However, in actual use, CNC milling machines with similar structures still have many defects. For example, after the existing milling machine completes the processing of the workpiece, the user needs to manually replace the processing head for re-processing, which leads to cumbersome operations during the processing process, and the work efficiency of the user cannot be improved, which is relatively inconvenient. During use, it brings certain impacts, so it is necessary to design a multi-station CNC milling machine to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-station CNC milling machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-station CNC milling machine, including a workbench and a rotating disk, a back plate fixedly installed on the top of the workbench, a hydraulic cylinder threadedly installed on the front end of the back plate, a rotating disk fixedly installed on the output end of the hydraulic cylinder, a mounting disk rotatably installed on the outside of the rotating disk, three different processing heads slidably installed on the inside of the mounting disk through a slider, a telescopic rod fixedly installed on the inside of the rotating disk, a mounting sleeve fixedly installed on the outside of the mounting disk, and a docking column corresponding to the slider movably installed on the inside of the mounting disk. Through the telescopic effect of the telescopic rod, one end of the telescopic rod can be extended into the inside of the through hole and squeezed with the processing head installed in the mounting disk, so that the processing head can be conveniently processed, and after the telescopic rod is contracted, the processing head can be driven to slide along the inside of the mounting disk under the adsorption effect of the magnet, so that the docking column can be mutually engaged with the slider, and the processing head is limited inside the mounting disk, which is more convenient during the replacement process.

[0006] Preferably, a magnet adsorbed to the top of the telescopic rod is fixedly mounted on the tail end of the processing head. After the telescopic rod is retracted, the magnet can drive the processing head to slide along the inside of the mounting plate, so that the docking column can engage with the slider.

[0007] Preferably, a through hole for the telescopic rod to move is provided on the rotating disk, and the telescopic rod can pass through the through hole to contact the tail end of the processing head. Through the telescopic effect of the telescopic rod, one end of the telescopic rod can be extended into the through hole to be pressed against the processing head installed inside the mounting disk, so that the processing head can conveniently perform processing.

[0008] Preferably, the docking post and the mounting sleeve are movably connected via a spring, the top of the docking post is arc-shaped, and the slider is provided with an arc-shaped groove that matches the docking post. The docking post can be squeezed by the squeezing action of the spring so that the top of the docking post can match the arc-shaped groove on the slider, thereby conveniently limiting the processing head inside the mounting plate.

[0009] Preferably, a motor is fixedly mounted at the bottom of the rear end of the rotating disk, a gear is fixedly mounted at the output end of the motor, a gear ring is fixedly mounted at the rear end of the mounting disk, and the gear ring and the gear are meshed with each other.

[0010] Preferably, a mobile frame is fixedly mounted on the rear end of the hydraulic cylinder, and the mobile frame is threadedly mounted on the back plate via a threaded rod. The mobile frame can be moved along the thread direction of the threaded rod by rotating the threaded rod, so that the mobile frame can be moved more conveniently during the processing, making the processing more flexible.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The utility model is provided with mutual cooperation between gears, gear rings, mounting disks and processing heads. The rotation of the output end of the motor can synchronously drive the meshing gear rings to rotate during the rotation of the gears, so that the mounting disk can rotate around the outer side of the rotating disk. Different processing heads can be replaced by rotating the mounting disk, which can increase the adaptability of the workpiece during use and be more efficient during use.

[0013] 2. The utility model is provided with a telescopic rod, a through hole, a processing head and a docking column that cooperate with each other. Through the telescopic effect of the telescopic rod, one end of the telescopic rod can be extended into the inside of the through hole and squeezed with the processing head installed in the mounting plate, so that the processing head can conveniently perform processing. After the telescopic rod is contracted, the processing head can be driven to slide along the inside of the mounting plate under the adsorption effect of the magnet, so that the docking column can be engaged with the slider, and the processing head is limited inside the mounting plate, which is more convenient during the replacement process.
