Detailed Description
The invention is further described with reference to the following drawings and detailed description.
As shown in fig. 1 to 4, a novel cylinder rotary diameter-changing circle correcting device comprises a mounting plate 11, a diameter-changing block 12, a driving assembly and a pneumatic bolt device 15.
The mounting plate 11 is an annular mounting plate.
This reducing block 12 has the polylith, is in proper order evenly circumference and arranges in one side of mounting panel, link up on each reducing block 12 and seted up mounting hole, locating hole.
This drive assembly includes drive shaft 13 and bearing 21, drive shaft 13 has a plurality ofly and be evenly distributed ground circumference and arrange in the opposite side of mounting panel 11, double sprocket 14 is installed to drive shaft 13 one end, all adopt the chain to link to each other between the double sprocket 14 of each drive shaft 13, the drive shaft 13 other end passes mounting panel 11 until stretching into to the mounting hole in, the drive shaft 13 other end is the hexagon head in order to block reducing block 12, be equipped with bearing 21 between drive shaft 13 and the reducing block 12, bearing 21 pastes the opposite side of locating mounting panel 11 mutually.
The pneumatic bolt device 15 comprises a cylinder 31, a copper sleeve 32 and a bolt 33, wherein the tail end of a cylinder shaft of the cylinder 31 is detachably connected with the bolt 33, so that the pneumatic bolt device is prevented from being stuck in the moving process. The copper sleeve 32 is sleeved on the cylinder shaft of the air cylinder 31, the copper sleeve 32 is fixedly arranged on the other side of the mounting plate 11, and the plug pin 33 can be inserted into the positioning hole of the variable diameter block 12 in a matching mode.
