[0063] The above embodiment discloses a transition device that can realize the mutual use of multiple chucks, wherein, when in use, the transition sleeve member 1 is pushed to be inserted into the port of the chuck body 5, at this time, the transition sleeve member 1 is fixed to the connecting rotating rod 6 by bolts, and then the limiting pressure plate 207 is pushed to drive the limiting slider 208 to slide along the inner wall of the lifting slide groove, when the limiting slider 208 contacts the inner wall of the linear slide groove, the limiting pressure plate 207 is pushed to drive the limiting slider 208 to slide along the inner wall of the linear slide groove, and when the magnet attracts the iron sheet 206, the limiting pressure plate 207 drives the limiting slider 208 to move under the drive of the magnet until the magnet moves to the bottom of the iron sheet 206 and contacts the lower surface of the iron sheet 206, so that the limiting pressure plate 207 can be conveniently installed, and then the roller end of the required model can be placed inside the transition sleeve member 1 according to actual needs, until the roller end contacts the outer wall of the limiting card plate, so the roller end can be preliminarily limited;

[0064] Then, the air pump is started to deliver gas to the inner cavity of the air delivery block 2013 through the air delivery pipe. At this time, the air delivery block 2013 delivers gas to the inner cavities of the annular air supply ring 2012 and the air supply pipe 306 respectively. In this process, the first limit rotating ring 2011 delivers the air in the inner cavity of the annular air supply ring 2012 to the inner cavity of the fixed air pipe 2015 through the air vent. At this time, due to the blocking of the port of the fixed baffle 2021 by the sealing baffle 2022, the gas cannot enter the inner cavity of the mobile air pipe 2014. At the same time, the air The air is continuously transported. At this time, the sealing baffle 2022 pushes the fixed baffle ring 2021 to move under the pressure of the air. At the same time, the air supply pipe 306 transports air to the inner cavity of the plurality of second telescopic airbags 304 through the annular air pipe 305 and the connecting air pipe. At this time, the plurality of second telescopic airbags 304 are expanded by inflation. At the same time, the second limiting rotating ring 301 drives the plurality of limiting slide plates 302 to slide along the inner wall of the supporting sleeve ring 7 and the connecting sleeve member 4 through the fixed push ring 303 under the push of the plurality of second telescopic airbags 304.

[0065] In this process, the chuck body 5 slides along the inner wall of the connecting sleeve 4 and the outer wall of the transition sleeve 1 under the push of the moving air pipe 2014 and the second limiting rotating ring 301. At the same time, the limiting pressing plate 207 drives the limiting slider 208 to slide along the inner wall of the linear slide groove under the drive of the chuck body 5 through the magnet and the iron sheet 206.

[0066] When the limit slider 208 contacts the inner wall of one end of the linear slide, the sealing baffle 2022 pushes the limit block 2019 to contact the inner wall of one end of the fixed air pipe 2015 through the connecting push rod 2018. At the same time, the limit block 2019 stops moving under the obstruction of the inner wall of the fixed air pipe 2015. At this time, the fixed baffle ring 2021 slides along the inner wall of the fixed air pipe 2015 and the outer wall of the connecting push rod 2018 under the pressure of air, and the mobile air pipe 2014 is moved along the fixed baffle ring 2021. The chuck body 5 continues to move under the push, so that the outer walls of the fixed baffle ring 2021 and the sealing baffle plate 2022 can be separated from each other, and then the air can be transported to the inner cavity of the mobile air pipe 2014 through the gap between the fixed baffle ring 2021 and the sealing baffle plate 2022. At this time, the chuck body 5 stops moving under the obstruction of the mobile air pipe 2014, and the positioning plug plate 2010 moves to the inner side of the annular groove 201 through the mobile slip ring 209 under the drive of the chuck body 5, so as to automatically push the chuck body 5;

[0067] Afterwards, air is transported to the inner cavity of the first telescopic airbag 205 through the mobile air pipe 2014. At this time, the first telescopic airbag 205 is expanded by inflation. At the same time, the iron sheet 206 is pushed away from the inner wall of the chuck body 5 by the first telescopic airbag 205, and drives the lifting slide bar 202 to slide along the inner wall of the chuck body 5. At this time, the limiting pressure plate 207 drives the limiting slider 208 to slide along the inner wall of the lifting slot through the magnet driven by the iron sheet 206 until the limiting pressure plate 207 contacts the outer wall of the roller end, so that the roller ends of different models can be automatically clamped.

[0068] During this process, the first spring 2017 pushes the sliding push plate 203 to slide along the outer wall of the fixed guide rod 2016 by rebounding. At this time, the fixed push rod 204 and the movable slip ring 209 are driven by the sliding push plate 203 to slide along the inner wall of the chuck body 5. At the same time, the positioning plug plate 2010 is inserted into the inner part of the annular groove 201 under the push of the movable slip ring 209, so that the chuck body 5 can be rotated and limited. At this time, the sliding push plate 203 stops pushing the fixed push rod 204 through the movable slip ring 209 under the obstruction of the positioning plug plate 2010. At this time, the iron sheet 206 continues to descend, so that the iron sheet 206 and the fixed push rod 204 can be separated from each other;

[0069] When it is necessary to release the clamping of the roller end, the above operation is reversed by pumping air through the air pump, which can first drive the iron sheet 206 to reset, thereby releasing the limit on the chuck body 5, and then pull the chuck body 5 to slide and reset, so as to conveniently release the clamping of roller ends of different models.

[0070] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
