Problems solved by technology

[0004] However, the screw-tightening mechanism of the automatic screw-tightening device in the prior art is a rigid structure, which will cause a certain impact force on the product when the screw is tightened in the downward direction, and the parts with low strength may even be damaged
[0005] In addition, the automatic screw tightening device in the prior art detects the locking condition of the screw through the tightening time and the stroke of the tightening mechanism. Since the judgment conditions of the slipped wire and the missing lock are the same, it cannot be distinguished, and the missing lock product can be re-screwed. Tightening is still a qualified product, while sliding wire products need to be scrapped
[0006] Furthermore, in the prior art, in order to ensure the consistency of the tightening torque of each screw, it is necessary to regularly test the tightening mechanism and verify its output torque. The current automatic tightening machine needs to disassemble the tightening mechanism before performing the test and verification. time consuming

Abstract

The invention discloses an automatic screw tightening device and a torque testing method thereof. The automatic screw tightening device comprises a support frame, a screw sucking mechanism, a screw tightening mechanism and a driving mechanism, wherein the screw sucking mechanism is arranged on the support frame and can move along a set track; the screw tightening mechanism is arranged on the support frame and can move along a set track; the driving mechanism is used for driving the screw sucking mechanism and the screw tightening mechanism to move; a first elastic piece is connected between the driving mechanism and the screw sucking mechanism; and a second elastic piece is connected between the driving mechanism and the screw tightening mechanism. By the automatic screw tightening device provided by the invention, the problem that products are impacted can be avoided.

Description

technical field [0001] The invention relates to the technical field of screw tightening tooling, in particular to an automatic screw tightening device and a torque testing method thereof. Background technique [0002] The automatic screw tightening device is used to automatically pick and place, tighten the screws and detect the locking condition of the screws. The basic principle is that after the screw products to be installed on the workbench reach the designated position, the automatic screw tightening device absorbs the screws, and then moves to the locking screw. position to complete the screw tightening action. [0003] The screws are arranged by the screw machine and fixed in position so that the automatic screw tightening device can absorb the screws. The screw automatic tightening device fixes the tightening mechanism by the clamping mechanism to realize the tightening function of the tightening mechanism. And by calculating the tightening time of the tightening ...
