Description

TECHNICAL FIELD

[0001] The utility model relates to a rotating disc technical field, concretely is a full -automatic rotating disc formula change shaft mechanism. BACKGROUND

[0002] With the development of manufacturing industry, the requirement of production efficiency and precision is higher and higher. In the traditional shaft part replacement process, manual shaft replacement has problems such as slow speed, poor precision and high labor intensity. For example, when a worker manually replaces lathe tool shaft in a machine shop, not only time is spent to disassemble and install, but also the position precision after each installation may be deviated, affecting the machining quality. In order to meet the production demand of large scale and high efficiency, a full-automatic rotating disc type shaft replacement mechanism emerges as the times require. This mechanism can accurately complete the replacement of shaft in a short time, and can repeat operation according to the preset program for many times, greatly improving the production efficiency.

[0003] The applicant finds that a full-automatic shaft changer is disclosed in Chinese patent with publication (announcement) number CN218707697U. The patent mainly comprises a shaft puller, a turnover table, a mandrel, a paper roll and a paper tube. The shaft puller is composed of two side columns, a distance beam arranged between the bottom of the two side columns, a cross beam arranged at the top of the front side of the two side columns, a cross beam lifting mechanism, a cross beam movable drag plate moving mechanism and a paper tube pushing mechanism. The turnover table is composed of a paper tube rack, a paper tube positioning support, a paper tube feeding mechanism, a movable turnover table, a movable turnover table turnover mechanism and a fixed turnover table. Compared with the prior art, the utility model has the advantages that the cooperation between the shaft puller, the turnover table, the mandrel, the paper roll and the paper tube can realize full-automatic shaft replacement with paper roll positioning, automatic shaft pulling, automatic roll unloading, automatic paper tube grabbing and automatic pipe penetrating, the efficiency is higher, and the practicality is strong.

[0004] Since only the shaft can be pulled out from the corresponding position during shaft replacement, the shaft insertion process cannot be smoothly completed, the shaft replacement task cannot be completely performed, and the height cannot be self-adaptively adjusted according to different shaft lengths. When the shaft is placed in the groove, since the shaft length cannot be accurately matched, there is a large gap between the shaft and the groove, which is too loose, and further causes the shaft to frequently shake in the groove. The shaking further causes the problem of too large radial gap between the shaft and the groove. During equipment operation, the shaft abnormally vibrates, which not only greatly reduces the stability of equipment operation, but also causes additional wear and damage to the shaft and other associated components. Therefore, a full-automatic rotating disc type shaft replacement mechanism is proposed. UTILITY MODEL CONTENTS
