Machine tool with floating shaft

Abstract

The invention discloses a machine tool with a floating shaft. The machine tool with the floating shaft comprises a machine tool Z-axis body, wherein the machine tool Z-axis body is arranged on a machine tool Z-axis guide rail; a rigid output shaft is arranged at the lower end of the machine tool Z-axis body; the floating shaft and a power device are arranged on the machine tool Z-axis body; and the floating shaft is arranged on the machine tool Z-axis body through an installing mechanism and can move under the action of the power device, so that the switching of the output shaft and the floating shaft is realized during processing. The machine tool with the floating shaft combines the technologies of a traditional floating shaft; the rigid output shaft and the floating shaft can be freelyswitched; when the common processing is carried out (for example, the surfaces of part of regular castings are polished), the quality of products can be ensured very well by adopting the rigid output;when the special processing is carried out (for example, the surfaces of part of irregular castings are burred, ground or polished), the undercutting problem of workpieces can be effectively avoidedby adopting the floating shaft output; and the surface quality and product yield of workpieces are improved.

Description

technical field [0001] The invention belongs to the technical field of machining equipment, in particular to a machine tool with a floating shaft. Background technique [0002] At present, most factories and even large engine manufacturing companies use manual or hand-held pneumatic and electric tools for deburring and grinding of engine casings, car bodies and other workpieces, which can easily lead to product defect rates. rise, and the efficiency is very low, and there are problems such as rough and uneven surface of the processed product. For this reason, some manufacturers have begun to use robots to install electric or pneumatic tools for automatic grinding. Compared with hand-held grinding, robot deburring can effectively improve production efficiency, reduce costs, and improve product yield. However, due to other factors such as mechanical arm rigidity and positioning errors , use robots to clamp electric and pneumatic tools to deburr. When dealing with irregular bu...
