Numerically-controlled horizontal-gantry fixed-girder milling machine for cycloid gears

Abstract

A numerically-controlled horizontal-gantry fixed-girder milling machine for cycloid gears is characterized in that the milling machine comprises a machine body (10), a stand column (1), a rectangular workbench (16), a fixed girder (2), a milling spindle box (7), a disc milling cutter (8), a vertical rotary indexing table (15) and a tail-ejector-pin support (11). The numerically-controlled horizontal-gantry fixed-girder milling machine is optimized in structure, convenient to operate, high in processing efficiency, applicable to processing the cycloid gears with few teeth, high in performance-cost ratio and applicable to processing of various batches of the cycloid gears in the cycloid speed reducer industry; when different shaping cutters are replaced, the milling machine is also applicable to other shaft parts, such as splines and motor rotor slots, in need of slotting; on the condition of same input-output ratio, user investment and occupation area are reduced, and equipment application range is widened.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing, and relates to a cycloidal gear processing machine tool, in particular to a numerically controlled horizontal gantry fixed beam cycloidal gear milling machine. In particular, it relates to single-index forming milling of cycloidal gears by using a numerically controlled horizontal gantry fixed-beam machine tool. Background technique [0002] The hobbing of cycloidal gears by ordinary hobbing machines is the main method of processing cycloidal gears at present, but there are some problems in this method: [0003] 1. Cutting with specially designed cycloidal high-speed steel hob is limited by the linear speed of the tool and the rigidity of the machine tool, and the overall hobbing efficiency is low, resulting in the disadvantages of a large number of investment equipment, a large number of operators, and a large floor area.

Problems solved by technology

[0003] 1. Cutting with specially designed cycloidal high-speed steel hob is limited by the linear speed of the tool and the rigidity of the machine tool, and the overall hobbing efficiency is low, resulting in the disadvantages of a large number of investment equipment, a large number of operators, and a large floor area.

[0004] 2. Due to the limitation of hobbing meshing principle, it is impossible to hob cycloidal gears with a small number of teeth

For cycloidal gears with a small number of teeth, the profiling method is usually used for profiling milling at present, which has low machining accuracy and precision, and requires a large number of profiling profiling, which is expensive

[0005] 3. Hobbing and wet cutting produce soot that pollutes the workshop environment, which is harmful to the health of operators and does not conform to the development direction of green manufacturing
