In actual use, the first detection core rod 10 or the second detection core rod 20 is clamped to the corresponding tip seat, the detection sleeve 30 is sleeved on the detection core rod which is clamped, the other detection core rod is clamped to the corresponding tip seat, finally, the position of the detection sleeve 30 is moved to enable the detection sleeve 30 to be sleeved on the two detection core rods at the same time, and the axial position of the detection sleeve 30 is moved, so that the coaxiality condition of the first tip seat 200 and the second tip seat 300 is detected quickly.
In this embodiment, the first nose cone 200 is clamped on a chuck of a machining device, the second nose cone 300 is mounted at the tail of the machining device, the first detection core rod 10 is clamped on the first nose cone 200, the detection sleeve 30 is completely sleeved on the first detection core rod 10, the second detection core rod 20 is clamped on the second nose cone 300, the axial position of the second nose cone 300 on the machining device is moved, so that the second detection core rod 20 is close to the first detection core rod 10, and finally the detection sleeve 30 is moved, so that the detection sleeve 30 is moved from one side of the first detection core rod 10 to one side of the second detection core rod 20, if the movement process of the detection sleeve 30 is smooth and has no resistance, it can be determined that the coaxiality of the first nose cone 200 and the second nose cone 300 is good, and the machining requirements are met.
In the present embodiment, the coaxiality of the double centers is completed by moving the inspection sleeve 30, and therefore, the fitting condition between the inspection sleeve 30 and the first and second inspection cores 10 and 20 is important. In the present embodiment, the inner hole diameter of the detection sleeve 30 is greater than the diameter of the first detection core rod 10 by 0.1mm, that is, a single-side 0.05mm gap exists between the inner hole of the detection sleeve 30 and the first detection core rod 10, so as to facilitate the movement of the detection sleeve 30; similarly, the diameter of the inner hole of the detection sleeve 30 is 0.1mm larger than the diameter of the second detection core rod 20, that is, a single-side 0.05mm gap exists between the inner hole of the detection sleeve 30 and the second detection core rod 20, which is convenient for the movement of the detection sleeve 30.
