Embodiment Construction
[0053] Such as Figure 1~2 As shown, an online detection device for the outer diameter of cylindrical parts in the spinning process is characterized in that it includes a ring frame mechanism located on the guide rail of the spinning machine tool, an axial movement mechanism of the ring frame, a lateral movement mechanism of the ring frame, and a ring frame mechanism. Vertical movement mechanism.
[0054] The ring frame mechanism includes upper and lower two semi-arc-shaped frames, the two are connected through concave and convex spigots to form a ring 4, and the lower end of the semi-arc-shaped frame below is connected with an inverted T-shaped support seat 6. The inner diameter of the ring 4 is greater than the outer diameter of the cylindrical part 5 .
[0055] 3 to 4 displacement sensors 22 are installed on the ring 4 , and an angle sensor 23 is installed on the end face of the bed head or bed end of the spindle 27 of the spinning machine through an outward coupling.

The invention discloses an online measuring device of the outer diameter of a cylindrical member in a spinning process. The device comprises a ring support mechanism, a ring support axial movement mechanism, a ring support lateral movement mechanism and a ring support vertical movement mechanism all arranged on spinning machine tool guide rails. The ring support mechanism comprises a circular ring and a support base supporting the circular ring. The inner diameter of the circular ring is greater than the outer diameter of a cylindrical member. At least one displacement sensor is installed on the circular ring. An angle sensor is installed on the end surface of either the head end or the tail end of a mandrel of the spinning machine tool. The displacement sensor and the angle sensor are connected with a signal conditioning module which is connected with a host computer. A data collection module and a data processing and analysis module are built in the host computer. The invention provides the reliable measuring device for high-precision online measurement of the outer diameter of a large-diameter cylindrical member subjected to spinning machining, provides measurement basis for quality control, can measure the outer diameter of a workpiece in real time, is high in measurement precision, does not need frequent shutdown for manual inspection, and is low in labor intensity.
Description
technical field [0001] The invention belongs to special detection equipment for diameter measurement, and in particular relates to an on-line detection device for the outer diameter of cylindrical parts in the spinning process, and is especially suitable for large-diameter thin-walled cylindrical parts. Background technique [0002] In the field of diameter detection, due to product structure and precision requirements, there are mainly three modes: online, on-machine and offline. The on-machine and off-line detection modes can be carried out by conventional detection methods such as outer micrometer, π ruler and ring gauge. [0003] When the thin-walled cylindrical parts involved in spinning processing have the characteristics of large diameter and long length (for example, the diameter reaches Ф600mm, the wall thickness is 0.5, the length reaches 4000mm, and the accuracy requirement is ±0.05mm), the particularity of its structure determines its spinning Press processing m...
