Multi-degree-of-freedom precision positioning fixture based on micro-texture laser preparation of ball-end milling cutter

Abstract

Provided is a multiple freedom degree precision positioning clamp based on ball head milling cutter micro-texture laser preparation. The invention relates to the multiple freedom degree precision positioning clamp, in particular to the multiple freedom degree precision positioning clamp based on ball head milling cutter micro-texture laser preparation. The invention aims at solving the problems that when a laser marking machine is applied to micro-texture preparation, each blade needs multiple positioning, the positioning precision is not high, and accordingly the processing efficiency is lowered. The clamp comprises a fixing base, a rotating base, an overturned driving component, a rotating driving component, a rotating plate, a clamp body, a connecting plate, a hinge and a fixing mechanism, wherein the fixing base is arranged on a workbench of the laser marking machine, and one end of the rotating base is connected with one end of the fixing base through the hinge; the lower surface of the rotating base is connected with the upper surface of the fixing base through the overturned driving component, the rotating plate is arranged on the upper surface of the rotating base through the rotating driving component, and the clamp body is arranged on the upper surface of the rotating plate; one end of the clamp body is connected with one end of the rotating plate through the connecting plate, and the fixing mechanism is arranged on the clamp body. The multiple freedom degree precision positioning clamp based on ball head milling cutter micro-texture laser preparation belongs to the field of machining.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom precision positioning fixture, in particular to a multi-degree-of-freedom precision positioning fixture prepared based on a ball-end milling cutter micro-textured laser, and belongs to the field of machining. Background technique [0002] Titanium alloys are widely used in aerospace and other fields due to their excellent properties such as high specific strength, good thermal strength, and corrosion resistance. However, titanium alloys are difficult to process. Compared with smooth surfaces, non-smooth surfaces have better wear resistance, so it has become a new approach to process micro-textures on the front and flank surfaces of the tool to improve the wear resistance and other properties of the tool. In the process of micro-texturing the front and flank faces of the ball end milling cutter, only one cutting face can be processed at a time. When micro-texturing of a large number of inserts, the time...
