Description
Technical field
The invention belongs to mechanical assembly technique fields, and in particular to a kind of howitzer bottom row's stern winding device and user
Method.
Background technique
It is a kind of novel to screw technology that conventional howitzer bottom row's stern, which screws technology,.Currently, common device is mostly using chain
The screw-fashion of pincers, specific screwing operations are as follows: i.e. by the artificial first pre- screw-in body component bottom internal screw thread 2~3 of bottom row's stern
Chain wrench portion of chain is wrapped in bottom row's stern outer pyramidal surface and locked, then firmly rotates chain wrench in the direction of the clock by button
Bottom row's stern is screwed in body component in place by handle, and this traditional screw-fashion has the following disadvantages: 1) stern is arranged at bottom
Outer surface is cone structure, and chain is since, there are certain taper, screwing operations chain is formed with the conical surface with bottom row's stern contact surface
The contact of section property line, contact surface is small, skids between screwing operations chain and bottom row's stern serious, in the case where revolving force action easily the bottom of by
Row's stern male cone (strobilus masculinus) forms cyclic annular impression and scratch (complete cycle direction), seriously affects product quality, and inefficiency, is unfavorable for criticizing
Amount production；2) bottom row stern, which screws required torque, to apply, and be unable to the size that real-time control bottom row's stern screws power, cause
The accuracy and reliability that bottom row's stern screws is poor, is unable to satisfy product design index request.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of howitzer bottom row's stern winding device and uses
