Transducer array element forming device for controlling pre-tightening force and operation method

Abstract

The invention provides a transducer array element forming device for controlling pre-tightening force and an operation method. The transducer array element forming device comprises a main body bracket, a thrust meter sensor, a thrust meter controller, an array element mounting base and a transducer longitudinal array element, a thrust meter sensor and an array element mounting base are mounted on the main body bracket, and the thrust meter sensor is connected with a thrust meter controller; one end of the thrust meter sensor is connected with the array element mounting base, and the other end is axially pushed through a thrust rod; the transducer longitudinal array element is mounted on the array element mounting base; the transducer longitudinal array element is mounted between the array element mounting base and the main body bracket; when the thrust rod applies thrust to the thrust meter sensor and the array element mounting base, a pre-tightening force is applied to the transducer longitudinal array element; and the thrust meter sensor, the array element mounting base, the transducer longitudinal array element and the thrust rod are mounted on the same straight line. According to the invention, the pre-tightening force of the screw during the assembly of the longitudinal array element of the transducer can be monitored, the product consistency and the qualified rate are improved, and the product cost is saved.

Description

technical field [0001] The invention relates to hydroacoustic engineering technology, in particular, to a transducer array element forming device and an operation method for controlling pre-tightening force. Background technique [0002] In the field of underwater acoustics, the transducer array is the core component of the sonar, and its manufacturing process steps often need to be strictly controlled, while the transducer array generally requires a large number of array elements to complete. It has high reliability and is widely used in the array of various types of transducer arrays. The vertical assembly is generally completed by manual assembly. Due to the large number of them, and it is currently difficult to achieve automatic assembly, there are too many steps involved in human participation, resulting in the consistency of the array elements is often not guaranteed, resulting in a decrease in the product qualification rate. [0003] In the past, when making the tran...

Problems solved by technology

[0004] When the number of array elements is large, the applied preload force will decrease due to long-term fatigue operation due to the replacement operation; the time required for glue curing is longer, and the frequency of array elements cannot be modified after the glue is cured, resulting in product cost It is impossible to know the array element pre-tightening force, which leads to operation based on experience, and causes no inheritance of the process when changing a product operation; based on these factors, the present invention seeks to design a device for optimizing the transducer array element Forming steps, while reducing human intervention in the production of transducer array elements, to ensure product consistency, improve work output and yield
