Specific implementation

[0013] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0014] Reference Figures 1-3 The utility model provides a kind of driving disc for automatically disassembling and assembling wheel set shaft end driving device, including driving disc 1, positioning and clamping surface 101, positioning and guiding surface 103 are arranged in continuous array with equal interval on the periphery of driving disc 1, inner ring inner wall 104 and inner ring end face 105 are arranged in sinking in driving disc 1;Center hole 102 is arranged in the middle of inner ring end face 105.

[0015] Specifically, three positioning and clamping surfaces 101 and three positioning and guiding surfaces 103 are arranged on the periphery of driving disc 1, three through holes are evenly arranged on the circumference of inner ring end face 105, and bolt 2 is respectively installed in the through hole.

[0016] Wheel set shaft end 4 is cylindrical, the surface is outer cylindrical surface 41, the end is provided with end face 42, center positioning hole 44 is opened in the center of end face 42, and threaded hole 43 is provided around center positioning hole 44.

[0017] When driving disc 1 is not installed to wheel set shaft end 4, positioning and guiding rod 3 is contacted with three positioning and guiding surfaces 103 on driving disc 1, so that driving disc 1 is centered and fixed in the center of three positioning and guiding rods 3;When driving disc 1 is installed to wheel set shaft end 4, inner ring inner wall 104 is sleeved on outer cylindrical surface 41, inner ring end face 105 is attached to end face 42, three bolts 2 pass through the through hole on driving disc 1 and are fixed by screwing into threaded hole 43, so that driving disc 1 and wheel set shaft end 4 are tightly connected as a whole.

[0018] Preferably, the clamping jaws 6 on the wheel lathe adopt a three-jaw synchronous centering clamping mode, the clamping heads on the clamping jaws 6 are driven by electric or hydraulic power to synchronously extend to contact the positioning clamping surface 101 and apply a certain clamping pressure, so as to clamp the driving disc 1, facilitating the taking out of the driving disc 1 from the positioning guide rod 3.

[0019] Preferably, the centering pin 5 on the wheel lathe is driven by electric or hydraulic power to extend through the center hole 102 and abut against the center positioning hole 44, so as to axially fix the wheelset shaft end 4.

[0020] Working principle: in use, the wheelset is lifted by the device to a specified height and automatically rotated to align, the driving disc 1 with the bolt 2 preassembled in the driving disc 1 is aligned with the wheelset shaft end 4, the device pushes the driving disc forward after aligning the driving disc 1 with the wheelset shaft end 4, so that the inner wall 104 of the inner ring is sleeved on the outer cylindrical surface 41, the end surface 105 of the inner ring is abutted with the end surface 42, at the same time, the bolt 2 passes through the through hole in the driving disc 1 and is screwed into the threaded hole 43 to be fixed, so that the driving disc 1 and the wheelset shaft end 4 are tightly connected as a whole; the clamping jaws 6 adopt a three-jaw synchronous centering clamping mode, the clamping heads on the clamping jaws 6 are driven by electric or hydraulic power to synchronously extend to contact the positioning clamping surface 101 and apply a certain clamping pressure, the centering pin 5 on the wheel lathe is driven by electric or hydraulic power to extend through the center hole 102 and abut against the center positioning hole 44, so as to realize the positioning and clamping of the wheelset; reversing the above steps can realize the automatic disassembly of the driving disc 1.
