Method for setting torsion constant value of assembling tool

Abstract

The invention discloses a method for setting a torsion constant value of an assembling tool. The method comprises the following steps: determining the maximum torsion technological value Tmax and the minimum torsion technological value Tmin of a product when the product is assembled according to the product; substituting Tmax and Tmin into the formula T=K*delta t+Tmin and getting a calculation result N; according to the calculation result, setting the assembling tool by taking N as a torsion value, assembling the product by adopting the assembling tool, measuring and recording the product torsion, after standing, carrying out second-time measurement and recording, if deviation exists, carrying out fine adjustment on the torsion value, and repeating the steps until the twice measurements are within the range of the technological values; and after verifying the torsion value to be rational, setting the torque value as the torsion constant value of the assembling tool. With adoption of the method, the weighted relationship is adopted for calculation to realize rational setting of a parameter so as to completely eradicate insufficient or excessive torsion during the assembling process, and the development demand of the manufacturing industry is met.

Description

technical field [0001] The invention relates to the technical field of assembly, in particular to a method for setting the fixed torque value of assembly tools such as torque fixed value wrench. Background technique [0002] With the development of society, assembly tools such as torque wrench are more and more widely used. During the application process, due to the attenuation of the fastener torque itself, it often leads to product defects. How to set a reasonable torque constant Value, to ensure that the torque is still within the process value range after attenuation has become the research direction of enterprise technicians. [0003] The technical solution in the prior art is an empirical method, that is, setting the fixed value of the torque wrench by virtue of work experience. Due to the different experience of different staff, the setting of the torque wrench will be different, and the work cannot be effectively guided. Moreover, due to the randomness of the settin...

Problems solved by technology

Due to the different experience of different staff, the setting of the torque wrench will be different, and the work cannot be effectively guided. Moreover, due to the randomness of the setting method and the lack of effective scientific management, the frequency of torque attenuation occurs during the production process. Higher, leading to the loss of product function, resulting in the risk of storage, repair, and even vehicle recall
