An infinitely extendable machine tool

Abstract

The invention relates to a machine tool capable of being extended infinitely. The machine tool comprises a main workbench and an extensible workbench. The main workbench comprises a first support leg, a second support leg and a main supporting platform. The extensible workbench is fixedly mounted on the left side of the main supporting platform. A first sliding groove and a second sliding groove are formed in the middle of the main supporting platform. Holding seats are connected at the right end of the main supporting platform, and main bearing seats are connected at the upper ends of the holding seats. A main rotary shaft is mounted in the main bearing seats. A main fastening device is fixedly connected at the left end of the main rotary shaft. An upper belt pulley is connected with the right end of the main rotary shaft. T-shaped supporting columns are arranged above the first sliding groove and the second sliding groove. Auxiliary bearing seats are connected on the upper portions of the T-shaped supporting columns. An auxiliary rotary shaft is mounted in the auxiliary bearing seats. An auxiliary fastening device is connected at the right end of auxiliary rotary shaft. The machine tool has the advantages of reasonable structural design, low production cost, convenience in operation and the like and has wide application range, and the defects of limited processing dimension, high production cost and heavy weight of conventional processing tools are overcome.

Description

technical field [0001] The invention relates to a machine tool, in particular to an infinitely extendable machine tool. Background technique [0002] As we all know, there are many types of existing processing machine tools, and the maximum working stroke is fixed. When the parts are too long, ordinary small machine tools cannot process them, and only large-scale processing machine tools can be selected. At present, most Due to limited funds, small and medium-sized enterprises cannot afford to purchase expensive large-scale processing machine tools. They can only take the form of outsourcing and send parts to partners for processing. It will cause certain damage to the shape of the parts, affect the surface quality of the parts, and have a certain impact on the economic benefits of the manufacturer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing device with reasonable structural design, low manufac...
