Description

Ultrasonic detection tool for automobile hub weld joint Technical Field The utility model relates to the technical field of product detection, in particular to an ultrasonic detection tool for automobile hub weld joints. Background The ultrasonic phased array technology utilizes a plurality of independent ultrasonic array elements, and realizes deflection, focusing and scanning of sound beams by precisely controlling the transmitting and receiving time (delay) of each array element. This flexibility enables adaptation to complex geometries of the wheel hub weld and enables high precision detection of defects inside the weld. Because of the complex weld in the automobile hub structure, in the prior art, an ultrasonic phased array detection device is generally adopted to detect the weld of the hub (the general detection position is the joint of the rim and the spoke). Specifically, the conventional ultrasonic phased array detection device comprises a water tank, a clamp arranged in the water tank, a manipulator arranged beside the water tank, an ultrasonic probe arranged on the manipulator and other components. When the ultrasonic detection device is used, the hub is fixed on the clamp, and the manipulator drives the ultrasonic probe to carry out position adjustment until the ultrasonic probe is adjusted to the corresponding position capable of detecting the welding line of the hub, so that subsequent detection work is carried out. However, in the actual use process, since the wheel hubs of different types are different in different batches, when the wheel hubs of different types are placed on the fixture in the water tank, the distance between the welding seam on the wheel hub and the ultrasonic probe in the initial state is different. At this time, the manipulator is required to perform corresponding position adjustment so that the ultrasonic probe can be accurately aligned with the weld position. However, the adjustment position of the ultrasonic probe has certain limitations due to the limitation of the range of the mechanical hand. When the size of the hub to be detected is smaller, the distance between the welding line on the hub and the ultrasonic probe in the initial state may be larger, and if the distance exceeds the adjustable range of the manipulator, the small-size hub cannot be effectively detected. The common solution is to replace the manipulator with a larger working range, but the solution is difficult to popularize and use on a large scale due to the reasons of high purchase cost, complex maintenance, limited factory building space and the like. Aiming at the problems, an ultrasonic detection tool for the welding line of the automobile hub is provided. The detection tool is designed to expand the detection range as much as possible by optimizing the structural design on the premise of not changing the type of the manipulator, thereby adapting to the detection requirements of hubs of different types and sizes. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides an ultrasonic detection tool for automobile hub weld joints, which utilizes a telescopic piece to connect an ultrasonic probe with an end effector of a manipulator, so that the flexibility and applicability of detection can be improved, the equipment upgrading cost can be effectively reduced, and an efficient and economic technical scheme is provided for automobile hub weld joint detection. In order to solve the problems, the utility model provides the following technical scheme: the ultrasonic detection tool for the automobile hub weld joint comprises a water tank, a manipulator arranged beside the water tank, an ultrasonic probe used for detecting the hub weld joint and a telescopic piece with a self-locking function, wherein two ends of the telescopic piece are respectively connected with an end effector and the ultrasonic probe on the manipulator, so that the distance between the ultrasonic probe and the manipulator can be adjusted by means of the telescopic function of the telescopic piece. As a further scheme of the utility model, the telescopic piece comprises a rod part with one end arranged on the end effector and a cylinder part with one end connected with the ultrasonic probe, the rod part is movably inserted and connected with the other end of the cylinder part, and the position of the rod part on the cylinder part is adjustable. As a further scheme of the utility model, the cylinder part is provided with a through groove communicated with the inside of the cylinder part along the length direction, one end of the rod part in the cylinder part is provided with a threaded hole, and the threaded hole is opposite to the through groove in position so as to enable the bolt to pass through and be connected in sequence. As a further scheme of the utility model, the telescopic piece further comprises a connecting plate arranged at one end of the cylinder part far away from the rod
