Description

Use control icons to perform statistical analysis of numerical data with smart tools. Abnormal warnings and out of control feedback correction methods

The present invention relates to a method for using control icons to perform statistical analysis of intelligent tool numerical data, abnormal warnings and out of control feedback corrections, in particular to a method that can be established through control charts to drive a screw drive tool to drive the screw during the locking process. Intelligent tool for quality characteristics measurement, recording, evaluation and torque monitoring and warning. Numerical abnormality warning and out of control feedback correction technology.

According to the rapid improvement of precision machining technology, the precision of the locking operation of high-precision locking parts (such as bolts or nuts) has also increased. For example, airplanes, ships, or vehicles require extremely high-precision torque values to lock screwed parts, so that the locked parts (such as fuselage members, hull members, tires, etc.) are locked to the above with high precision and correct torque. On the locking member of the carrier. If an operation error occurs due to negligence of the locking torque value, it will often cause serious land, sea and air traffic accidents, and irreparable regrets will occur.

Furthermore, screw driving tools (such as ratchet wrenches or sleeve wrenches) have long been widely used in mechanical assembly or maintenance of various work tools or workstations. In the application field of high-precision locking, for each locking or disassembly operation, there are certain operating procedures and preset locking torque value specifications. Once the operation is excessively applied, it may be This causes the collapse of the locking piece and damages it, which results in delays in the subsequent operation procedures, which in addition to increase the cost of working hours, will also cause extreme inconvenience and troubles in the locking operation.

In order to solve the above deficiencies, the related technical field has developed a torque wrench with the function of detecting and displaying the torque value. The conventional torque wrench can display the torque value during the locking operation, allowing the user to perform the locking operation. The locking operation of the locking element can be performed according to the known torque value, so that it can be ensured that the locking torque value of the locking element can meet the preset locking torque value. Although the conventional torque wrench can avoid the damage of the locking parts due to excessive force operation; however, it does not have the function of torque value transmission and monitoring management, so that it cannot truly realize the torque data output monitoring and The management function, if this kind of conventional torque wrench is applied to a large mechanical assembly factory; or in each assembly workstation of an automobile assembly factory, due to the large number of operators on site, it is impossible to configure each workstation The locking torque value of the locking part is effectively monitored and managed, so that the operator can only check whether the applied locking torque reaches the preset torque value. Once the operator is distracted and ignores monitoring the lock When the torque value is set, it is impossible to effectively and comprehensively control the locking quality of the locking parts of each assembly workstation. As a result, the conventional torque wrench can only be used as a personal torque operation display. Effective utilization results in extremely low industrial utilization value.

According to what we know, the control chart is a statistical method that uses sampling methods to continuously measure, record and evaluate important quality characteristics in the work process at regular intervals to supervise and check whether the process is under control. That is, the control chart is used to detect whether there are abnormalities in the manufacturing process for further investigation. If the control chart is used properly, it can help companies improve the process performance at a lower cost but effectively, and the process performance will ultimately reflect the competitiveness of the company. Generally speaking, the variation of the locking operation process of high-precision locking parts cannot be improved by simply using the control chart. Therefore, it is necessary to conduct in-depth research on the locking operation process of the precision locking parts to understand the source of system variation. Experiments are needed to confirm the causality, here Only to improve and control the reasons for the variation of the system, how to develop a monitoring technology that integrates the control chart technology and applies it to the locking operation process of the precision locking parts has become an urgent challenge and solution for the related technical fields.
