Background

The purpose of the torque spot check is to ensure the effective control of the bolt torque of the engine and promote the effective development of the quality work of the engine.

The static torque of a fastener needs to be periodically detected in an engine assembly line, a manual tightening tool is used for adding a torque which is gradually increased along the tightening direction of the bolt to the fastened bolt until the moment when the bolt generates tightening movement again, the recorded torque value of the movement which is just generated is the static torque.

The current common scheme in the industry is to use a digital display wrench or an indicator wrench for sampling inspection, and fig. 1 is a common wrench structure which mainly comprises a wrench extension rod 101, a handle 103, a digital display panel 102, a ratchet head and other parts. The torque spot check personnel use the tool to carry out spot check on stations with torque requirements, and the spot check is manually recorded in a torque spot check recording table. If the torques of various types of machines need to be detected, the torques need to be recorded respectively so as to classify and analyze the detected static torques according to the types of the machines.

The above scheme has the following defects:

1) paper edition data recording is not beneficial to long-term storage and tracing of data;

2) when the sampling inspection is manually controlled, the wrench rotates by an angle, and the sampling inspection results of different staff are poor in consistency;

3) the filling proportion of the form in the working elements of the spot-checking staff is large, and time is wasted;

4) and engineers manually input the data into a computer for sorting and statistical analysis, so that time and cost waste of secondary processing exists.
