Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and in particular to a CE coating device for PCBN cutting tool edges. Background Technology

[0002] CE coating for PCBN cutting tools is a novel PVD coating technology that forms a thin film layer with a thickness of no more than 2μm on the surface of PCBN material through physical vapor deposition. This coating significantly improves the thermal stability, corrosion resistance, and wear resistance of the cutting tool, thereby improving its cutting performance and ultimately increasing tool life and productivity. The working principle is as follows: 1. The PCBN cutting tool is placed in a vacuum chamber and evacuated to a high vacuum; 2. The substrate is heated to a set temperature; 3. A reactive gas (such as N2, C2H2, etc.) is introduced; 4. Plasma is excited, and the target material is sputtered and deposited on the tool surface. However, the coating process requires manual flipping and re-fixing of the PCBN cutting tool midway, which is cumbersome and inefficient. Therefore, it is necessary to design a highly automated and efficient CE coating device for PCBN cutting tool edges that does not require manual disassembly of the PCBN cutting tool during the coating process. Summary of the Invention

[0003] The purpose of this invention is to provide a PCBN cutting tool edge CE coating device, which has the advantages of high automation and high efficiency.

[0004] The technical solution adopted is as follows:

[0005] A PCBN tool cutting edge CE coating device includes a vacuum chamber, within which a plasma generation system, a heating and temperature control system, a gas control system, and a workpiece clamping system are installed. The workpiece clamping system includes a worktable with a horizontal slider on it. A vertical slider is located above the horizontal slider. A first rotating tube is horizontally rotatable on the side of the vertical slider. A mounting block is located at the end of the first rotating tube. A second rotating tube is horizontally rotatable on the side of the mounting block. A clamping mechanism is located at the free end of the second rotating tube. A baffle is vertically mounted on the upper part of the worktable. A base plate is located on the side of the baffle. A pressure plate is horizontally slidable on the upper part of the base plate. A third electric telescopic rod connected to the pressure plate is mounted on the base plate.

[0006] Preferably, the horizontal slider is vertically provided with a plurality of first electric telescopic rods, the upper and lower ends of which are connected to the vertical slider.

[0007] Preferably, the upper end of the vertical slider is provided with a first motor, the first motor is provided with a drive gear, and the first rotating tube is provided with a driven gear that meshes with the drive gear.

[0008] Preferably, the upper surface of the workbench is provided with an elongated groove, a horizontal slider is slidably disposed in the elongated groove, and a second electric telescopic rod is horizontally fixedly disposed in the elongated groove, the second electric telescopic rod being connected to the horizontal slider.

[0009] Preferably, the mounting block is provided with a second motor, the second motor including an output shaft, the output shaft being coaxially and fixedly connected to the second rotating tube.

[0010] Preferably, the clamping mechanism includes an electric three-jaw chuck, which has three inwardly opening arc-shaped plates.

[0011] Compared to existing technologies, the advantages are:

[0012] The PCBN cutter's center hole is fitted onto three curved plates. A three-jaw chuck controls the movement of these plates to fix the PCBN cutter. The position of the PCBN cutter is adjusted by sliding the horizontal slider, sliding the vertical slider, and rotating the first rotating tube. During coating, the rotation of the first rotating tube adjusts the angle of the PCBN cutter. When coating is needed on the side of the PCBN cutter facing the mounting block, the PCBN cutter is rotated to a vertical position and placed on the bottom plate. The pressure plate is moved, and the pressure plate and baffle clamp the PCBN cutter. The three-jaw chuck moves the curved plates to release the PCBN cutter. Then, the three curved plates are moved to insert into the center hole of the PCBN cutter from the other side and fix it, thus coating the remaining side of the PCBN cutter. The coating process does not require manual disassembly of the PCBN cutter, resulting in a high degree of automation and efficiency. Attached Figure Description
