Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical rollers, in particular to a tool for detecting cylindricity and end surface flatness. Background Art

[0002] Since the rolling parts of the rollers are relatively heavy and large in size, there is a lack of equipment that can test their accuracy in the commonly used maintenance equipment. In addition, the drafting rollers and heat-setting rollers are connected to the gearbox drive shaft with flanges, and the flange surfaces have more or less vertical deviations from the roller surface. Excessive vertical deviation will cause the roller surface to run out of tolerance.

[0003] The rollers of existing staple fiber devices are generally large, and it is impossible to effectively inspect and accept many large rollers that are repaired or purchased, resulting in a series of problems such as large roller runout and large vibration during equipment operation;

[0004] At the same time, during the maintenance process of the rollers of the post-spinning drawing machine and the heat setting machine, the rollers often jump out greatly after being reinstalled, and need to be disassembled again. The gaskets are made by calculating the jump value for adjustment. This disassembly and assembly takes 3 hours of work, which is very labor-intensive. The production process is tight during special periods, which will have a negative impact on production efficiency. Utility Model Content
