Dual-conical-surface supporting rotary tool device

Abstract

The invention relates to a dual-conical-surface supporting rotary tool device. The dual-conical-surface supporting rotary tool device comprises a bracket, outer rotary supporting wheel shafts, a rotary drive gear shaft, inner rotary supporting wheel shafts, idle gear shafts, an inner gear rack, a choke plug, a tool head and the like, wherein the outer rotary supporting wheel shafts and the inner rotary supporting wheel shafts appear in pairs, and number of the outer rotary supporting wheel shafts or the inner rotary supporting wheel shafts is greater than or equal to 3; the inner gear rack and the choke plug are fixedly assembled together, and the inner gear rack and the choke plug have a superposed rotary center line; the inner gear rack is supported on roller paths of the outer rotary supporting wheel shafts and the inner rotary supporting wheel shafts; a gear on the rotary drive gear shaft is engaged with gears on the two idle wheel shafts; the gears on the two idle gear shafts are engaged with an inner gear on the inner gear rack; and the tool head is fixedly mounted on the inner gear rack. With the adoption of the dual-conical-surface supporting rotary tool device, a rotary tool obtains relatively high processing linear speed with relatively low rotation speed, breaks through the limit that a part must adopt a tool of the same size or a smaller size to process as a result of the small-size geometrical characteristic, and obtains better processing quality and a longer tool service life.

Description

technical field [0001] The invention relates to a double-cone support rotary tool device, which belongs to the field of mechanical processing equipment. Background technique [0002] The R&D, manufacturing and application of industrial robots is an important symbol to measure the strength and level of a country's technological innovation and high-end manufacturing. In the next few years, the domestic demand for more than 2.4 million industrial robots accounts for about 70% of the world's total demand. Calculated in ten thousand yuan, the market size of industrial robots exceeds 720 billion yuan. However, at present, about 90% of domestic robots use imported precision reducers, and some imported precision reducers account for nearly 1 / 3 of the total cost of robots, which is one of the bottlenecks restricting the development of my country's robot industry. A crucial reason for this phenomenon is that the internal tooth surface grinding machine tools required for precision red...

Problems solved by technology

However, at present, about 90% of domestic robots use imported precision reducers, and some imported precision reducers account for nearly 1 / 3 of the total cost of robots, which is one of the bottlenecks restricting the development of my country's robot industry.

A crucial reason for this phenomenon is that the internal tooth surface grinding machine tools required for precision reducers in my country have outstanding problems such as low grinding line speed, poor grinding accuracy, and low grinding efficiency, which have caused precision reducers Low precision, high noise, short life

The key problem is that the inner tooth surface is a closed curved surface, and the processing tool used must be smaller than the diameter of the addendum circle, which results in a small tool, which makes it very difficult to achieve the required processing speed, and also causes excessive wear of the tool. Induces excessive cost and loss of precision
