Description

Technical Field

[0001] The utility model relates to the technical field of reducer production, in particular to an intelligent device with torque detection and gasket selection functions. Background Art

[0002] During the assembly process of the reducer, there is a certain assembly gap between the bearing end face and the shaft hole platform on the reducer housing. In order to reduce this gap, it is necessary to add appropriate gaskets. The current method is mostly to manually measure the size of the gap and then select a suitable gasket based on experience. However, due to human factors or subjective judgment, this method is prone to errors, thereby affecting the assembly accuracy of the reducer. Some other gap measurements can also be achieved through equipment, such as the gasket selection machine described in the existing patent CN 113878322 A. However, the equipment has a complex structure and uses multiple servo motors for control. The high cost is not conducive to popularization and application. In addition, in terms of torque measurement of the reducer, manual measurement using a torque wrench is currently mostly used, but this method is prone to measurement errors. Alternatively, standard torque detection equipment can be purchased, but as a separate torque detection process, it will increase production costs. Utility Model Content

The gasket selection component 4, the depth detection component and the torque measurement component 505 are all integrated into one device, thereby having high integration. Since most of the work is completed automatically, the workers only need to perform simple operations, and only one worker needs to be arranged to complete it easily, thereby achieving the effect of low labor intensity and saving labor costs. The measuring assembly 5 automatically detects and records the data and sends it to the intelligent selection component 7. The recorded depth detection data and torque detection data are analyzed and the detection result curve is generated to provide data support for process improvement.
