[0003] Most of the existing tooling is manual, huge in size, and heavy in weight. The installation intensity is very high, the installation time is long, the efficiency is low, and a large number of hoisting operations are required during installation. The risk factor is very high. The existing cylinder rounding devices are all full-circle structures, which are not conducive to the hoisting of the cylinder and cannot achieve automatic clamping. Most of the existing tooling is special and cannot be changed in diameter, so multiple sets of tooling need to be prepared in daily production to meet the needs. The increase in the number of tooling requires a large area for storage. Summary of the invention

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figures 1 to 4 As shown, a novel cylindrical rotating diameter-changing roundness calibration device comprises a mounting plate 11, a diameter-changing block 12, a driving assembly and a pneumatic latch device 15.

[0019] The mounting plate 11 is an annular mounting plate.

[0020] The variable diameter block 12 has a plurality of pieces, which are uniformly arranged in the circumferential direction on one side of the mounting plate. A mounting hole and a positioning hole are formed through each variable diameter block 12 .

[0021] The drive assembly includes a drive shaft 13 and a bearing 21. The drive shaft 13 has multiple bearings 21 that are evenly distributed and circumferentially arranged on the other side of the mounting plate 11. A double-row sprocket 14 is installed at one end of the drive shaft 13. The double-row sprockets 14 of each drive shaft 13 are connected by a chain. The other end of the drive shaft 13 passes through the mounting plate 11 until it extends into the mounting hole. The other end of the drive shaft 13 is a hexagonal head to clamp the reducer block 12. A bearing 21 is provided between the drive shaft 13 and the reducer block 12. The bearings 21 are arranged on the other side of the mounting plate 11.

[0022] The pneumatic latch device 15 includes a cylinder 31, a copper sleeve 32, and a latch 33. The end of the cylinder shaft of the cylinder 31 is detachably connected to the latch 33 to prevent it from getting stuck during movement. The cylinder shaft of the cylinder 31 is sleeved with a copper sleeve 32, and the copper sleeve 32 is fixed on the other side of the mounting plate 11. The latch 33 can be matched and inserted into the positioning hole of the reducer 12.

[0023] The working principle of the present invention is as follows: a bearing 21 is provided between the drive shaft 13 and the mounting plate 11, and the drive shaft 13 can rotate freely;

[0024] Each drive shaft is connected by a chain, and the other drive shafts can be linked by rotating any one drive shaft, so that multiple diameter-changing blocks can rotate at the same time to produce a diameter-changing effect;

[0025] The pneumatic latch device 15 acts on the positioning reducer block 12, and the pneumatic latch device 15 is positioned by inserting into the positioning hole on the reducer block 12;

[0026] The reducing block here is formed by rotating the four arc edges of the reducing block at different angles to form hoop circle diameters of different sizes, and finally a calibration device can be used to quickly switch the reducing blocks to clamp and calibrate cylinders of various sizes.

[0027] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
