Description
Technical field
The invention belongs to mechanical assembly technique fields, and in particular to a kind of hexagonal binding nut automatic tightening method.
Background technology
When external screw thread and internal thread are tightened, there are the rotary shaft of a square thread relative to another square thread rotary shaft with
Inclined state starts to screw, and to generate the possibility that external screw thread and internal thread are suppressed, while there is also external screw threads due to putting
Seated position deviation and screw thread meshing point cannot be found, to be revolved in internal thread overhead, causing cannot normal engaging-in possibility.
In screw thread tightening method disclosed in Japanese Unexamined Patent Publication 2006-315097, pass through the axis of one side pressing and tightening tool
One square thread of portion's card sum in the state that hand of spiral of wanting to relax on one side makes axle portion direction rotate, is detected by external screw thread and interior spiral shell
The vibration that the mutual collision of line thread generates.Thus it detects the engaging-in of external screw thread and internal thread and screws togather starting position.This spiral shell
The vibration and other noise and vibrations that the mutual collision of thread of external screw thread and internal thread generates cannot be distinguished in line tightening method.
In the screw thread tightening method of Toyota Motor Corporation rep. disclosed in Japanese Unexamined Patent Publication 2016-060231, to detect impact noise
Intensity is criterion, detection threads starting position.
However, above two kinds of screw thread tightening methods are used to hand-held screw thread and tighten, it is not used to the spiral shell of automatic assembly line
Line tighten with non-threaded internal thread pedestal stationary state, therefore, it is difficult to accurately realize external screw thread under non-threaded state and non-
Screw togather that one side of internal thread under state is fixed to tighten.
