Problems solved by technology

This is time consuming and inefficient
[0007] At the same time, when the screwdriver is stuck in the flat notch of the cable, friction is likely to occur between the screwdriver and the sleeve, resulting in inaccurate measurement results when the torque wrench measures the torque of the nut.

Abstract

The invention provides a dummy neck mounting auxiliary device, comprising a connecting cap, a casing pipe and a ratchet clamping port, wherein one end of the connecting cap is used for being connected with a torque wrench, and the other end is connected with one end of the casing pipe; a nut hole used for sleeving a neck nut of a dummy is formed in the other end of the casing pipe; the ratchet clamping port comprises a ratchet wrench and a clamping port used for being clamped on a clamping groove of a neck steel rope of the dummy; the casing pipe is provided with a notch, and the clamping port of the ratchet clamping port passes through the notch and is clamped on the clamping groove of the neck steel rope; and the ratchet wrench is arranged in the notch and applies torque to the neck nut of the dummy through rotating in the notch. By adopting the dummy neck mounting auxiliary device, the neck nut of the dummy can be fastened continuously, the fastening time is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a nut installation auxiliary device, and in particular to an automobile test dummy neck installation auxiliary device. Background technique [0002] Dummy is an important equipment for data collection in automobile crash tests (such as vehicle crash tests, sliding table tests, etc.). During the crash test, the state of the dummy directly affects the accuracy of data collection. Therefore, the dummy needs to be checked and calibrated after the crash test. Among them, the neck calibration is one of the many calibration tests of the dummy, and its purpose is mainly to check the hardness of the neck rubber. According to regulations, the neck of the dummy must be calibrated after reaching the number of tests. Therefore, the neck often needs to be disassembled and installed, and the torque of the neck nut must reach 1.36±0.27Nm. However, the neck structure of the Hybird III series dummy is rather special, and the neck nut is very...
