Abstract

The invention relates to a double-nut tightening device with an automatic counting function. The double-nut tightening device comprises a connecting shaft support frame, a double-tightening head, a moment strain gage, a first servo motor, a double-tightening head clearance adjustment device, a connecting shaft, a second servo motor, a counting display screen, a second servo motor support frame, a guide rail mobile table, a third servo motor, a base, a linear guideway and a ball screw. The double-nut tightening device with the automatic counting function has the beneficial effects that two nuts can be tightened simultaneously in an automatic production line, the tightened nuts are ensured to meet the technical requirements according to a set moment numerical value, and the automatic production efficiency is improved.

Description

A kind of double nut device for screwing up with automatic counting function
Technical field
The present invention relates to a kind of double nut device for screwing up with automatic counting function, specifically use servomotor and drive ball-screw drive movable workbench, use servomotor and realize being with sleeved tappet head to rotate fastening nut, belong to the automation equipment field.
Background technology
Tightening of bolt and nut is a not only important but also loaded down with trivial details job, and artificial fastening nut is difficult to reach very high unitized and standardization.At present, along with the development of Flexible Production manufacturing technology and constantly increasing of popularization and labour cost, production line automation requires more and more higher, needs a kind of bolt and nut automatic screwing device.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of double nut device for screwing up with automatic counting function.
The present invention is achieved by the following technical solutions: a kind of double nut device for screwing up with automatic counting function, comprise the connecting axle bracing frame, two tappet heads, the moment foil gauge, the first servomotor, two tappet head spacing adjusting devices, connecting axle, the second servomotor, the counting display screen, the second servomotor bracing frame, the guide rail travelling carriage, the 3rd servomotor, base, line slideway and ball-screw, servomotor is installed on the base, ball-screw is connected with servomotor, the guide rail travelling carriage is connected with leading screw and is installed on the horizontal guide rail, by bracing frame connecting axle and the second servomotor are installed above the guide rail travelling carriage, the connecting axle other end connects two tappet head spacing adjusting devices, two the first servomotor one sides are connected with two tappet head spacing adjusting devices, opposite side respectively is equipped with a tappet head, and two all are equipped with torque sensor above the tappet head.
The usefulness of this invention is to have realized carrying out simultaneously in automatic production line the operation of tightening of two nuts, can according to the moment numerical value of setting, guarantee that all nut unifications of tightening reach specification requirement, have improved automated production efficient.
