Technical Field

[0001] The utility model relates to the technical field of sensor processing, in particular to a sensor inner core bushing press-fitting tool. Background Art

[0002] The core component inside the sensor is usually called the sensor core, also called the sensor chip or sensor element. The sensor core bushing refers to the outer casing or shell used in the sensor to protect and support the core components inside the sensor (such as the sensor chip, sensor element, etc.).

[0003] The sensor core bushing press-fit tool is a special tool used to press-fit the bushing with the chip or component inside the sensor during the sensor manufacturing process. However, when using the existing sensor core bushing press-fit tool, it is necessary to first load the material, then press-fit, and finally manually take out the press-fitted sensor core to complete the unloading. The operation is cumbersome, time-consuming and labor-intensive, and the press-fit operation cannot be performed continuously, and the work efficiency is low.

[0004] Therefore, we proposed a sensor inner core bushing press-fitting tooling to solve the above problems. Utility Model Content
