Mandrel assembly assembling equipment and operation method

Abstract

The invention discloses core shaft assembly assembling equipment which is used for assembling a core shaft to a shaft barrel, the core shaft is provided with a channel, the shaft barrel is provided with a plug-in opening and an assembling channel matched with the core shaft, the plug-in opening is communicated with the channel, and the assembling channel is matched with the core shaft. The mandrel assembly assembling equipment comprises an electrical control mechanism, an assembling base and an assembling mechanism, the assembling base is used for fixing the shaft barrel and supporting the mandrel, the assembling mechanism comprises a primary positioning assembly and a precise positioning piece, the primary positioning assembly is controllably connected to the electrical control mechanism, the precise positioning piece is controllably connected to the electrical control mechanism, and the secondary positioning assembly is controllably connected to the precise positioning piece. The primary positioning assembly is installed on the assembling base in the mode that the core shaft can be pushed to enter the channel and used for primary assembling of the core shaft, and the accurate positioning piece is installed on the primary positioning assembly and used for secondary assembling of the core shaft so that the core shaft can be assembled at the preset position of the shaft barrel.

Description

technical field [0001] The invention relates to the technical field of mandrel assembly production, in particular to mandrel assembly assembly equipment and an operation method. Background technique [0002] Mandrel assembly is one of the common types of parts, and there are various types of mandrel assemblies, including air shafts. The air shaft is a shaft that can form protrusions on the surface after high-pressure inflation, and the protrusions on the surface can be quickly retracted after deflation. The inflatable shaft has the characteristics of large load capacity, and can balance the force, and can rewind the heavy load items. It is currently widely used in metallurgy, papermaking, printing and dyeing, weaving, rubber, wire and other industries. [0003] In the production process of the air expansion shaft, the staff need to manually assemble the air bladder and the mandrel, but the assembly force exerted by the staff on the mandrel is not easy to control, and it is ...

AI Technical Summary

Problems solved by technology

However, with the long-term use of the semi-automatic assembly device, its moving mechanism will be worn, resulting in deviations in its motion stroke, making the assembly position of the mandrel substandard and affecting the processing quality

The production error problem caused by the damage of this kind of parts requires the maintenance personnel to carry out extensive maintenance on the device, which is not only cumbersome to operate, but also the maintenance cost is too high

[0005] In addition, if a semi-automatic assembly device is used to assemble bladder shafts of different specifications, the staff needs to adjust the moving mechanism of the semi-automatic assembly device to change the moving stroke of the moving mechanism. This assembly method is not only not convenient to operate, but also the moving mechanism The adjustment accuracy of the moving stroke is relatively low, and it cannot be applied to the processing of the air shaft that requires assembly accuracy

[0006] In addition, because the air bladder is made of rubber, it is inevitable that it will be bent during storage and transportation, which increases the difficulty of mandrel assembly. The bladder is completely coaxial, so that the mandrel moves in a direction that deviates from the central axis of the bladder during assembly, causing the mandrel to push against the inner wall of the bladder, resulting in deformation or even damage to the bladder
