The utility model solves the technical problems by the following technical scheme:
the utility model provides a two-stage sleeve, which comprises an inner sleeve, an outer sleeve, an inner sleeve insert, a transmission shaft, an inner sleeve and outer sleeve connecting blocks and a spring, wherein the inner sleeve is sleeved on the outer sleeve; the rear end of the transmission shaft is provided with a connecting hole, the front end of the transmission shaft is provided with a groove, and the front end of the transmission shaft is connected with the inner sleeve; the groove of the inner sleeve is buckled with the inner sleeve embedded sheet; the outer sleeve is sleeved outside the inner sleeve and the transmission shaft, and the inner sleeve and outer sleeve connecting block is connected with the transmission shaft and the outer sleeve; the spring is sleeved outside the transmission shaft, and the spring is located in a cavity between the inner sleeve connecting block and the outer sleeve connecting block and the transmission shaft.
In the utility model, the inner sleeve is used for screwing a bolt with smaller size;
preferably, the inner diameter of the inner sleeve is 15.5 mm;
preferably, the length of the inner sleeve is 44 mm.
In the utility model, the outer sleeve is used for screwing the bolt with larger size;
preferably, the inner diameter of the outer sleeve is 28 mm;
preferably, the outer sleeve has a length of 252 mm.
In the utility model, the connecting hole is used for connecting a tightening gun.
In the utility model, the inner sleeve and the outer sleeve connecting blocks are used for connecting the inner sleeve and the outer sleeve.
In the present invention, the transmission shaft is used to provide torque to the inner sleeve and the outer sleeve.
In the utility model, the inner sleeve insert is used for fixing the transmission shaft and the inner sleeve.
In the present invention, the spring is used for buffering and separating the inner sleeve and the outer sleeve.
The working principle of the double-stage sleeve is as follows: when the bolts at the bottom of the front axle and the rear axle are in a small specification, the tightening gun ascends under the control of the PLC, the tightening gun continuously ascends when the bolts contact the outer sleeve, the spring is compressed under the action of external force, the inner sleeve is ejected out under the action of the transmission shaft and is sleeved with the bolts in a small specification, and the tightening gun acts to finish the tightening process; when the front and rear axle bottom bolts are in a larger specification, the bolts do not ascend when contacting the outer sleeve any longer, the tightening gun works, and the tightening process is realized.
The positive progress effect of the utility model is as follows: the double-stage sleeve can adapt to two bolts with different specifications, and improves the working efficiency.
