Numerical-control screw rod polishing machine tool

Abstract

The invention discloses a numerical-control screw rod polishing machine tool which comprises a machine body shell and a base, wherein a working platform and struts are firmly disposed on the base, a driving mechanism is installed on the working platform, the tail end of the driving mechanism is connected to a guide rail on the working platform through vertical slide, the bottom of the working platform is connected to the base by a dovetailed guide rail through horizontal slide, the driving mechanism comprises a rotary machine head, the rotary machine head is connected to a lifting machine head, the lifting machine head is connected to a ball screw rod by an outer-hexagonal flange screw, a pressing cover is installed on the top end of the ball screw rod, a lifting driving device is firmly disposed on the pressing cover, and a support is also disposed on the lower end of the pressing cover. The numerical-control screw rod polishing machine tool disclosed by the invention adopts a numerical-control system, is driven by an alternating current servo unit, has a multi-axis control function, can quickly realize automatic processing with high efficiency and high precision, has a full-sealed complete machine structure, is equipped with functions such as dust collection and water curtain circulation, and truly realizes effects such as environmental protection, energy saving and safety production.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a numerically controlled screw polishing machine tool. Background technique [0002] In our country, the screw polishing of extruders is all processed manually, and the processing workshop is seriously polluted, and environmental protection issues are not to be discussed. The products processed by hand have low precision, poor consistency, and high repair rate. It is impossible to guarantee the same Batches of products can find exactly the same products; in addition, the technical requirements of manual polishing are high, personnel training is difficult, and there is a shortage of technical personnel. Due to the close contact between people and equipment, the health of operators is threatened by manual polishing, and there are safety hazards in operation. Frequent safety accidents, poor safety, and easy to cause occupational dust disease; manual polishing not only ...

Problems solved by technology

[0002] In our country, the screw polishing of extruders is all processed manually, and the processing workshop is seriously polluted, and environmental protection issues are not to be discussed. The products processed by hand have low precision, poor consistency, and high repair rate. It is impossible to guarantee the same Batches of products can find exactly the same products; in addition, the technical requirements of manual polishing are high, personnel training is difficult, and there is a shortage of technical personnel. Due to the close contact between people and equipment, the health of operators is threatened by manual polishing, and there are safety hazards in operation. Frequent safety accidents, poor safety, and easy to cause occupational dust disease; manual polishing not only has low efficiency and low output, but also leads to high product prices; and product quality varies from person to person, poor consistency, and inconsistent product quality. People have realized this deficiency and improved it. The traditional CNC screw polishing machine includes a fixed platform and a moving platform. The fixed platform is located above the moving platform. The moving platform and the fixed platform are connected by four telescopic links. , the upper ends of the four telescopic connecting rods are respectively connected to the first servo motor. The grinding wheel is installed on the moving platform and connected to the moving platform in rotation. Driven CNC Turntable

Four telescopic connecting rods are used to drive the motion platform for telescopic movement. It is relatively unstable during polishing, and the displacement cannot be precisely controlled, so the polishing effect cannot be satisfactory.
