Automatic arc slab rough grinding machine

Abstract

The invention provides an automatic arc slab rough grinding machine which comprises a base, stand columns, an arched girder and an adjustable working platform in the middle of the base. The two ends of the arched girder are fixedly connected with arched girder lifting devices arranged on the stand columns, and the arched girder lifting devices drive the arched girder to slide along the stand columns synchronously in the vertical direction. A grinding head lifting device and a circular motion mechanism are arranged on the arched girder, and the grinding head lifting device is fixed to the circular motion mechanism and drives a grinding head device fixed in the grinding head lifting device to make contact with or be separated from the surface of a workpiece fixed to the adjustable working table. Water is sprayed on the grinding head device so that wet grinding can be conducted between the grinding head device and the workpiece during work. The circular motion mechanism is matched with a long chain fixed to the arched girder, and drives the grinding head lifting device to do the circular motion in a rail direction of an arc-shaped guide rail on the arched girder and to grind the workpiece on the adjustable working table. By means of the automatic arc slab rough grinding machine, accuracy and efficiency of grinding the workpiece are improved, the working environment for workers is improved, and grinding powder is prevented.

Description

Technical field [0001] The invention belongs to the technical field of stone processing equipment, and in particular relates to an automatic rough grinding machine for an arc plate, which is used for accurately processing the outer diameter of the stone arc plate. Background technique [0002] With the improvement of people’s living standards, the decoration of natural stone has quickly entered the lives of the people. We often see roadside roads in urban construction, station squares are flat with natural color patterns on the ground, and the floors and walls inside and outside the prosperous high-rise buildings are magnificent. The hall and walls of the hotel’s dining hall are magnificent and majestic round pillars with colorful and sleek colors stand at the entrance of the hotel. Most of them are decorated with natural stone materials. The stone itself has high hardness, corrosion resistance and various patterns and colors. The characteristics not only meet the functional requ...

Problems solved by technology

The continuous growth of the market size and demand of the stone decoration industry has driven the development of related downstream supporting industries, and prompted stone manufacturers to continuously improve their processing levels to meet increasingly standardized and mature market demand, especially the actual production of stone columns for decoration. During the process, the method of use is manual dry grinding. The operator holds a small angle grinder in his hand, compares the circular template with the arc surface, and grinds it a little bit. The sound of grinding is harsh, and the completion of a standard-sized arc surface is not only labor-intensive, but also requires high technical requirements for operators. More importantly, the quality is poor and the output is low. The average output per person and per shift is at most 2 to 3 square meters. Defects restrict the application of curved stone in a wider range, so it is necessary to propose improvements
