Detailed description of the invention
Below the utility model is described in further details.
A kind of lining withdrawing device, this device comprises pulls pin 1, overcoat 2, fairlead 3, collet 4, support set 5 and handle 6, wherein, pull pin and 1 be threaded connection with overcoat 2, its plunger is cone, the outer surface of the inner surface of overcoat 2 and fairlead 3 is threaded connection, the inner surface of the outer surface of collet 4 and fairlead 3 is interference fit, the end of collet 4 reclines by support set 5 and overcoat 2, on collet 4, diameter has uniform groove compared with small end, the width of groove is 1mm, axially uniform by 30 °, the length of groove is 2/3rds of collet 4 length, collet 4 has serration with lining 7 contact positions, the cone of 1 the plunger of pulling pin can distending collet 4.
The course of work of the present utility model is as follows:
Overcoat 2 and fairlead 3 are threaded connection, and collet 4 be interference fit with fairlead 3, pull pin 1 and overcoat 2 be threaded connection.Rotary handle 6 rotates and pulls pin 1, and it is moved downward, and struts collet 4 by 1 the termination of pulling pin, and on collet 4, outer wall is carved with serration, can make it tightly abut in lining 7 inwalls.
Collet 4 reclines after lining 7 inwalls, is rotated further and pulls pin 1, it is moved downward until prop up frock 8, pulls pin 1 no longer to continue to move downward, and can make on the contrary collet 4 drive lining 7 to move upward, and constantly rotates and pulls pin 1, can slowly extract lining 7.Extract after lining 7, opposite spin pulls pin 1, until lining 7 comes off.
