Abstract

The invention relates to a large screw hole reaming device, in particular to a reaming machine. A motor is used for providing power; a belt is connected with a worm; a worm wheel is used for providing transmission to drive a reamer bar; a lead screw is arranged in the reamer bar; and a Huff clip, a planet gear, a transmission nut, a plane thrust bearing and a hand wheel are arranged on the reamer bar. The reaming machine is provided with compact transmission and feeding components which are convenient for the drilling and reaming operations in the narrow space, and has two working modes of electric operation and manual operation, thereby having high efficiency and easy control of precision, reducing the construction period and improving the economic benefit. Meanwhile, each of the power, transmission and feeding components utilizes a dismountable connection, thereby being convenient for the transport, assembly and disassembly of the device and greatly reducing the labor intensity of workers.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to large screw hole reaming equipment for on-site installation. Background technique [0002] At the installation site of the construction company, for example, during the ship production and installation process, a large screw hole is drilled on the steel plate, and a reamer is required. These reaming machines are large in size and heavy in weight, and are inconvenient to carry and operate in narrow cabins, which will have a negative impact on the production and installation progress of ships. And existing general-purpose portable reamer, its reamer diameter is little, and motor power is insufficient, does not possess the processing ability of large screw hole. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reaming machine which overcomes the defects of large size, heavy weight and difficult handling of existing ...
