The invention discloses a thread sleeve mounting and rotary pressing device, and relates to the technical field of mounting of a thread sleeve for a rail vehicle aluminum alloy vehicle body. The device comprises an electric wrench connection flange, an electric wrench lock pin, an electric wrench lock pin locking O ring, an electric wrench connection flange locking pin, an electric wrench connection flange locking pin O ring, a screw rod limiting clamping ring, a screw limiting gasket, a reducing thread sleeve, a screw rod, a pressing sleeve, a torsion friction O ring, a pressing sleeve lifting clamping ring, an axial thrust bearing, a positioning pin, a deep groove bearing, a depth positioning flange, a depth positioning protection ring, a thread sleeve lock pin protection sleeve and a depth groove bearing positioning clamping ring. Labor intensity of an operator in mounting of a lock pin thread sleeve can be reduced, production efficiency is improved, the noise of a working site is reduced while the mounting quality of the lock pin thread sleeve is ensured, the device is suitable for long-time operation and batched production environments, the number of operators can be saved, cost is reduced, and mounting quality of the lock pin thread sleeve is improved.
Description
technical field [0001] The invention relates to the technical field of installation of threaded sleeves for aluminum alloy car bodies of rail vehicles, in particular to a threaded sleeve installation and spinning device. Background technique [0002] As a special fastener, the threaded sleeve with locking pin has the characteristics of high bonding strength, strong shock resistance and outstanding corrosion resistance. It is widely used in the manufacture of aluminum and aluminum alloy vehicle bodies in the railway industry. like Figure 1 to Figure 3 As shown, threaded sleeve 20 with locking pin comprises four threaded sleeve lock pins 20-1 and threaded sleeve 20-2, and threaded sleeve 20-2 is provided with internal thread 20-2-1, external thread 20-2-2 and four Each outer wall groove 20-2-3, the bottom of each threaded sleeve locking pin 20-1 is correspondingly spot-welded on the top of an outer wall groove 20-2-3. Since the threaded sleeve 20 with locking pin has the spe...
