Description
Technical field
Track vehicle manufacturing field is the utility model is related to, particularly a kind of subway train bushing assembling device.
Background technology
At present, in train bogie production, the bushing press-mounting in pressing sleeve workpiece is treated, more use manual operationss, inconvenient,
Low production efficiency, press fitting is uneven, and surface fitting is not close and easily generation sleeve outer surface scratches, and influences to assemble quality.
To improve work efficiency and being more uniformly distributed press fitting, existing enterprise devises bushing press-mounting bolt, but is using
In, it is found that screw thread is easy to damage.In addition, screw head also easily damages pressing sleeve, cause the service life of bolt and pressing sleeve very
It is low, it is necessary to make substantial amounts of bolt and pressing sleeve carry out it is spare, on the one hand, manufacture cost greatly improves, and press fitting efficiency is low；The opposing party
Face, the workpiece after press fitting, press fitting uniformity also have much room for improvement.
The Chinese invention patent application of Application No. 201510611397.2, a kind of entitled " bushing of its innovation and creation
It is pressed spiral shell
Bolt and its pressing method ", it includes pressing sleeve screw rod, nut, two pressing sleeves and two ring flanges；Pressing sleeve screw rod includes
Screw head and screw rod bar portion；Two pressing sleeves are respectively the first pressing sleeve and the second pressing sleeve, and two ring flanges are respectively head flanges
With afterbody flange；In the screw rod bar portion, since screw head, head flanges, the first pressing sleeve, second are sequentially coaxially set with
Pressing sleeve, afterbody flange and nut；The outside diameter of each ring flange is all higher than the outside diameter of pressing sleeve.
Above-mentioned patent application, although being once pressed, energy two bushings of synchronous press mounting, press mounting bolt wearability is good, and press fitting is closed
Lattice rate is high.It remains desirable, however, that manually nut, two pressing sleeves and two flanges etc. are sleeved on pressing sleeve screw rod successively, then
Manually nut is tightened, carries out pressing sleeve.After the completion of pressing sleeve, also need manually to remove all parts from pressing sleeve screw rod successively, serve as a contrast
After set completes pressing sleeve, coordinate with pressing sleeve screw rod close, manually remove extremely difficult, and be also easy to damage bushing.It is in addition, this
Under structure artificial labor intensity, inefficiency, can only be adapted to the press fitting operation of small lot, be not suitable for large batch of automated production
The needs of line.
