Description

Technical Field

[0001] The utility model relates to the field of polishing equipment, in particular to a round tube polishing module with automatic tension adjustment. Background Technique

[0002] At present, in the bent tube polishing industry, sand belts are mainly used for polishing. Later, polishing wheel type bent tube polishing machines appeared on the market, such as the Chinese utility model patent with the authorization announcement number CN213795916U, the Chinese utility model patent with the authorization announcement number CN207415082U, etc. However, since the polishing wheel cannot be opened and tightened, when the pipe diameter changes or the polishing wheel is worn to a certain extent, automatic adjustment cannot be achieved, and the polishing wheel needs to be replaced, which not only increases the replacement operation but also cannot fully utilize the polishing wheel, resulting in waste.

[0003] For the existing bent tube polishing machine of Chinese patent CN2023117980468, its tension control is achieved through an adjusting wheel and a driving wheel. However, its transmission is driven by a belt. If the belt breaks, it is troublesome to replace, delaying the construction period, with high requirements for the assembly accuracy of workpieces and poor transmission accuracy. Content of the Utility Model

[0004] The utility model provides a round tube polishing module with automatic tension adjustment, which has high transmission accuracy and can automatically adjust the tension.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a round tube polishing module with automatic tension adjustment. The module is fixed on a support plate, and the support plate is fixed on a workbench. A first servo motor and a second servo motor are fixed on the support plate. The module includes a first external gear slewing bearing, a second external gear slewing bearing, a tension control track plate, a main driving wheel, and a planetary polishing module. One side of the first external gear slewing bearing is fixed on the support plate, and the second external gear slewing bearing is fixed on the other side of the first external gear slewing bearing. The second external gear slewing bearing is sleeved in the positioning groove of the main driving wheel. There are also three groups of planetary polishing modules on the main driving wheel. Corresponding channels are processed on both the tension control track plate and the main driving wheel.

[0006] Further, a transmission gear is installed at the shaft end of the first servo motor, and the transmission gear is meshed with the external gear of the first external gear slewing bearing for transmission; a belt gear is provided at the shaft end of the second servo motor, and the belt gear is in transmission cooperation with the external teeth of the main driving wheel through a belt.

[0007] Further, the first external gear slewing bearing includes a first external gear and a first inner wheel, the second external gear slewing bearing includes a second external gear and a second inner wheel. The first inner wheel is fixed in a preset installation groove on the support plate, the second external gear is fixed on the first inner wheel, and the tension control track plate is fixed on the side of the first external gear through bolts.

[0008] Further, the planetary polishing module includes an impeller swing block, a secondary transmission wheel set, a rotating gear, and a pin shaft. The secondary transmission wheel set includes a first transmission wheel meshing with the second external gear and a second transmission wheel cooperating with the rotating gear. A hundred-leaf wheel is installed outside the rotating gear. One end of the pin shaft is fixed on the impeller swing block, and the other end sequentially passes through the main transmission wheel and the groove of the tension control track plate, and a bearing is installed at the end, and the bearing rolls in the groove of the tension control track plate.

[0009] Further, both the secondary transmission wheel set and the rotating gear are fixed on the impeller swing block through fixed shafts and bearings.
