Abstract

The invention relates to a flexible rotary workbench for preparing a physical vapor deposition (PVD) coating on a tool. The flexible rotary workbench comprises a driving rod (1), a lower rotary table (2), an upper rotary table (3), a thrust ball bearing (4) and clamping body fixing rods (8). The thrust ball bearing (4) is arranged between the upper rotary table (3) and the lower rotary table (2). A big gear (5) and pinions (6) are arranged in the upper rotary table (3). The pinions (6) are engaged with the big gear (5). The big gear (5) is in interference fit with the driving rod (1). The upper rotary table (3) is engaged with the pinions (6). A cover plate is arranged at the upper end of the upper rotary table (3). The clamping body fixing rods (8) penetrate through the cover plate (7) and are connected with the pinions (6). The clamping body fixing rods (8) are driven by the pinions (6) to revolve and rotate. Revolution and rotation of the tool to be coated can be achieved through the cooperation of the flexible rotary workbench and a clamping body matched with the workbench, so that the surface of the tool to be coated is evenly coated with required coating materials, and the coating thickness is uniform.

Description

[technical field] [0001] The invention relates to the technical field of PVD coating preparation for cutting tools, in particular to a flexible rotary workbench for preparing PVD coatings for cutting tools. [Background technique] [0002] With the development of modern machining industry towards high precision, high speed, dry cutting, environmental protection and low cost, higher requirements are put forward for tool performance. As traditional tool materials, high-speed steel or cemented carbide is becoming more and more difficult to meet the development needs of the modern machining industry. Ultra-hard nano-micron Physical Vapor Deposition (PVD) coating has excellent properties such as high hardness, wear resistance, oxidation resistance, and low friction. service life. At present, PVD coating technology has been widely used in the surface of cemented carbide milling cutters, drill bits, oil hole drills, step drills, taps, reamers, indexable milling inserts, turning in...
