Pressfit method and equipment capable of measuring interference force

Abstract

The invention relates to a pressfit method and pressfit equipment capable of measuring interference force, in particular to a press working method and press working equipment. The method comprises the following steps of: setting the standard pressure value required by a finished product; pre-pressing a part, measuring the current pressure value during pre-pressing, and comparing the pressure value measured during pre-pressing and the standard pressure value; when the pressure value measured during the pre-pressing reaches the standard pressure value, pressing for the secondary time; and when the current pressure value does not reach the standard pressure value, finishing processing. In the pressfit method and the pressfit equipment capable of measuring the interference force, defective products which cannot reach the breakout effort can be picked up in the production process; during pressing, the part is pressed to a specific position for the first time, and the position is half or one third the total pressfit stroke; and according to the setting of different products, if the measured pressure value reaches the requirement of a product, the pressfit of a secondary step is performed, and the product is continuously pressed in place, so that the full inspection of the key index of the breakout effort is realized.

Description

technical field [0001] The invention relates to a part processing equipment, especially a press. Background technique [0002] In the process of processing, the two parts that need to be press-fitted together through interference fit are press-fitted together. The traditional method is to press-fit with a hand press or a pneumatic press, and it is impossible to control the press-down during the press-down process. There is no way to judge whether the disengagement force between the two parts can meet the product requirements. If the disengagement force is to be measured, only destructive experiments can be carried out, and the product will be scrapped, and full inspection cannot be realized. Contents of the invention [0003] The invention provides a processing method for testing the force of pressing in during the process of pressing down, so that defective products that cannot reach the release force can be directly picked out during the production process, which include...
