Precise numerical control machine tool

Abstract

The invention discloses a precise numerical control machine tool. The precise numerical control machine tool comprises a machine body. One side of the lower end of the machine body is rotatably connected with an oil cylinder. A bearing rod is rotatably connected to the tail end of a piston rod of the oil cylinder in a sleeving mode. Connecting rods are rotatably connected to the two ends of the bearing rod in a sleeving mode. One ends of the connecting rods are rotatably connected to one side of the lower end of the machine body in a sleeving mode. Two ends of the bearing rod are provided withfirst rotating wheels. One side of the lower end of the machine body is fixedly provided with two mounting pieces. A first fixing shaft is rotatably connected to the two mounting pieces jointly in asleeving mode. According to the precise numerical control machine tool, the position of a roller can be conveniently controlled, so that the roller or a bottom plate makes contact with the ground; when the roller makes contact with the ground, the position of the roller is convenient to adjust, positions of the bottom plate and the machine body relative to each other can be well adjusted and fixed, the stability of the machine body can be guaranteed, the machining quality can be improved, and meanwhile, the position of a first baffle can be well fixed, the situation that the first baffle collides with the machine body excessively is avoided, effective shielding can be ensured, and workers are protected.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a precision numerical control machine tool. Background technique [0002] CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces with arbitrary cone angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads. It can perform grooving, drilling, reaming, reaming and boring, etc. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. The basic components include processing program carrier, numerical control device, servo drive device, Machine tool body and other auxiliary devices. [0003] However, the mass of the existing CNC lathes is relatively large, and generally there are machines to carry and place them. When f...

Problems solved by technology

[0003] However, the mass of the existing CNC lathes is relatively large, and they are generally transported and placed by machinery. When fine-tuning, many workers are required to carry them, and the labor intensity is high. Moreover, when the existing protective plate is closed, it will collide with the machine body, which is easy The baffle is damaged, deformed, etc., which is not conducive to ensuring the airtightness. For this reason, we propose a precision CNC machine tool to solve the above problems
