Efficient double-face polishing equipment for multi-model nodular cast iron well lids

Abstract

The invention relates to the technical field of nodular cast iron well lid polishing, in particular to efficient double-face polishing equipment for multi-model nodular cast iron well lids. The efficient double-face polishing equipment comprises a rack, a positioning and clamping assembly, an overturning and clamping assembly, a surface polishing assembly and a hole polishing assembly. The overturning and clamping assembly comprises two sets of side wall clamping mechanisms which are arranged to be perpendicular to each other, and an overturning mechanism. The side wall clamping mechanisms arearranged at the output end of the overturning mechanism. The overturning mechanism comprises a first support frame, a second servo motor, a first rotating shaft, an overturning plate and a clamping disc, the two ends of the first rotating shaft are in shaft connection with the side walls of the two sides of the first supporting frame correspondingly, and the output end of the second servo motor is fixedly connected with one end of the first rotating shaft. According to the efficient double-face polishing equipment for the multi-model nodular cast iron well lids, multi-face polishing and positioning hole polishing operation can be efficiently and accurately conducted on the nodular cast iron well lids, the labor intensity of workers is relieved, the working efficiency is improved, and thepracticability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of grinding of nodular cast iron manhole covers, in particular to a high-efficiency double-sided grinding equipment for multi-model nodular cast iron manhole covers. Background technique [0002] Ductile iron manhole cover is a kind of ductile iron products. Nodular cast iron obtains nodular graphite through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially improves plasticity and toughness, so as to obtain higher strength than carbon steel. Ductile cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and wear resistance. Parts with high performance requirements. Ductile iron has rapidly developed into a cast iron material that is second o...

Problems solved by technology

[0006] In order to solve the above technical problems, a high-efficiency double-sided grinding equipment for multi-model ductile iron manhole covers is provided. This technical solution solves the need for grinding of ductile iron manhole covers before use. Most of the existing grinding techniques for ductile iron manhole covers Manual hand-held grinding equipment is used for grinding and processing. This method is labor-intensive and the grinding precision is low, which affects product quality. There are still some ductile iron manhole cover grinding equipment on the market that can automatically polish ductile iron manhole covers, but now Some equipment cannot be turned over. When grinding the ductile iron manhole cover on both sides, manual auxiliary turning operation is required, and it cannot adapt to the grinding process of different types of ductile iron manhole covers, and the scope of use is limited.
