A column dismantling machine

Abstract

The invention discloses an upright post cylinder disassembling machine. The Upright post cylinder disassembling machine comprises a movable worktable (2), a sliding rack (12), a hydraulic lifting frame (9), a rotary system (40) and a clamping device (11); a lifting platform is placed in a floor slot; a base (13) is mounted above the floor slot, and the clamping device is fixed on the base; tracks (1) are pre-embedded at the ground at two sides of the floor slot in parallel; the worktable is mounted on the tracks (1); a ground track is arranged at one side vertical to the floor slot and is provided with at least one sliding rack; a linear guide track (10) is mounted on an upright post at the inner side of the sliding rack; the hydraulic lifting frame is mounted on the linear guide track; the rotary system is mounted in the hydraulic lifting frame by a secondary track (26). The Upright post cylinder disassembling machine solves the manual assembly and disassembly problem of large-sized hydraulic oil cylinders, so the quality and efficiency in assembly and disassembly are improved, the object circulation problem in the assembly process is solved, and the upright post assembly and disassembly machine meets the operation of oil cylinders with various standards and different structures.

Description

technical field [0001] The invention relates to a special machine for assembling and dismantling coal oil cylinders, in particular to a column dismantling machine. Background technique [0002] In recent years, with the rapid development of the coal mining industry, fully mechanized mining hydraulic supports have been widely used, and the manufacture of the key components on fully mechanized mining hydraulic supports: columns and jacks has also developed. However, during this development process, people have focused on the process control of manufacturing and processing. Machining equipment has become the key point of improvement and production means in this industry, and assembly and disassembly equipment are still at a very primitive stage. . Many companies are still using manual operations. Most of the column bores are between 250-500mm, and the length is also between 1.2m-2m. The bore, volume and weight are very large, and assembly and disassembly are very difficult. T...

AI Technical Summary

Problems solved by technology

Many companies are still using manual operations. Most of the column bores are between 250-500mm, and the length is also between 1.2m-2m. The bore, volume and weight are very large, and assembly and disassembly are very difficult. The threaded guide sleeve requires 5-8 workers to assemble in the original way of manual grinding, and the work efficiency is extremely low

[0003] During the assembly process, the requirements for the verticality and concentricity of the workpiece are also very high. A little carelessness of the sealing ring and guide ring will cause edge trimming and damage, resulting in waste

If the sealing ring and guide can be found in time during the assembly process ring If the trimming and defects of the cylinder are replaced in time, it can also reduce some losses. Once the overall assembly is completed, it is found during the pressure test that the column needs to be disassembled and reworked. The volume of the oil cylinder is very large, and rework is time-consuming and laborious. It also seriously affects production. schedule, the cost of rework is very expensive, and the quality of rework cannot be guaranteed

[0004] Although there are now several companies that have also produced this type of assembly machine, some of them cannot meet the operation of the entire assembly process due to their simple structure and poor manufacturability, and the performance of the equipment cannot meet the full specifications and various structures. Requirements; Some are too complicated to operate and the performance is not satisfactory, and there are many problems due to mutual interference between processes.
