Chain stretching and correcting machine

Abstract

The invention relates to the technical field of mining circular ring chain production equipment, in particular to a chain stretching and correcting machine. Load borne by the chain stretching and correcting machine during working is extremely high, most existing equipment is high in integration degree, and once parts are damaged, the maintenance cost is high, and the debugging difficulty of the equipment is high. The chain stretching and correcting machine comprises a machine frame, a guide rail assembly, a static machine base, a movable machine base and a stretching clamp assembly; the machine frame is formed by connecting a main base and a tail base through a supporting beam; the static machine base is fixed on the main base; the movable machine base is movably arranged on the supportingbeam in an assembled mode; a clamping head of the stretching clamp assembly is connected with the static machine base and the movable machine base; the guide rail assembly comprises a front supporting plate, a rear supporting plate, a middle guide rail, an input guide rail and an output guide rail which are installed on the static machine base, and the movable machine base and the machine frame.According to the chain stretching and correcting machine, the equipment failure rate and the maintenance difficulty are greatly reduced, the maintenance cost is reduced, the defects that existing stretching equipment is high in fault rate, high in maintenance difficulty, high in cost and the like are overcome, and the continuous operation time of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of production equipment for mining circular link chains, in particular to a chain stretch correction machine, which is used for automatic stretch correction equipment for finished product shaping and test load loading of circular link chains on a circular link chain assembly line . Background technique [0002] Mining circular link chain is an important load-bearing component on the coal mine scraper conveyor. The working environment of the circular link chain is very harsh, and it bears a huge impact load. With the emergence of high-power coal mine scraper conveyor, the chain load is further increased; Therefore, in the processing of large-scale mining circular link chains, the technical requirements for finished product shaping and test load loading detection have been improved. The precision requirement is higher. Most of the existing stretch correction machines are automatic production equipment with a...

AI Technical Summary

Problems solved by technology

Most of the existing stretch correction machines are automatic production equipment with a high degree of integration. The strict requirements on the matching accuracy of the winding and card positions and the huge working load lead to a high failure rate of the equipment and increase the equipment cost. The operating cost is specifically manifested in the fact that the tensile parts (such as moving parts such as clamps) that directly bear the impact force are more likely to be damaged by friction, and the cooperation between the chain and the various parts of the equipment will also appear deviation during operation, which further aggravates the stress of the stressed parts. Abrasion and reduced machining accuracy; repair of damaged parts usually requires the replacement of the damaged parts as a whole, for example, if the guide slideway of the fixture and the chuck (or chuck) is damaged, the machine base needs to be disassembled and repaired or even replaced as a whole , not only time-consuming and labor-intensive, but also greatly increase the maintenance and repair costs in the later stage, increase the difficulty of equipment debugging, and seriously affect production efficiency
