Abstract

The utility model discloses an ultrasonic probe follow-up device. An ultrasonic probe is connected with a sliding block through a probe fixing frame; the angle direction of the probe fixing frame can be fine adjusted on the sliding block; the sliding block moves horizontally along a guiding plate that moves vertically on a cover plate; two sliding roller sets are arranged at the left side of an upper framework while one sliding roller set is respectively arranged at the upside and the underside of the upper framework; the upper framework and a lower framework are connected to form a frame structure which can be oppositely fixed and adjusted; the cover plate is screwed on the lower framework; a pressing plate is placed in the frame structure formed by the upper framework and the lower framework and is connected with the cover plate by a bolt passing through the lower framework; a spring is sleeved on the bolt between the pressing plate and the lower framework, thus a follow-up compressing mechanism is formed; one sliding roller set is mounted on the pressing plate; and five groups of sliding roller sets can slide on a curve sliding rails. The ultrasonic probe follow-up device is capable of following up according to the shape of the curve sliding rail to ensure that the normal of the ultrasonic probe and the normal of the curve sliding rail are consistent.

Description

The ultrasonic probe hunting gear

Technical field

The utility model belongs to technical field of nondestructive testing, particularly a kind of ultrasonic probe hunting gear.

Background technology

Ultrasound examination is one of the most frequently used method of material tests, has detected object scope factory, detects that the degree of depth is big, defect location is accurate, speed is fast, highly sensitive, simple to operate, harmless, and be convenient to advantage such as on-the-spot use.Therefore, it is that domestic and international application is the most extensive, frequency of utilization is the highest and a kind of faster Dynamic Non-Destruction Measurement of development.General checkout equipment is the gantry type frame structure, has 2 independent scanning arms can finish synchronous scanning.U.S. PANAMETRICS company develops the ultrasonic automatic checkout system of ARGUS level high-performance robotic arm twin beams framework; The Kazakhstan flies the C scanning system and adopts the portal frame cantilevered, its ultrasonic probe can move along X, Y, Z direction on line slideway, for satisfying curved surface scanning requirement, its probe has the degree of freedom of angle axle A, B, and all is that DC servo motor drives (" USL Ultrasonic C-Scan water spray detection system flies the application in the compound substance detection in the Kazakhstan ").Said system is on the basis of line slideway, by the control motor movement, guarantees that ultrasonic probe is vertical with the normal direction of workpiece measured point, is not suitable for the simple structure of curve slide rail, low degree-of-freedom.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure, easy to maintenance, ultrasonic probe hunting gear that can be applicable to curve slide rail guiding.

The technical scheme that realizes the utility model purpose is: a kind of ultrasonic probe hunting gear, comprise upper skeleton, lower skeleton, pressing plate, cover plate, spring, guide plate, slide block, probe fixed mount, slip set of rollers, ultrasonic probe links to each other with slide block by the probe fixed mount, this probe fixed mount can be at slide block upper angle directional trim, this slide block moves along the guide plate horizontal direction, and this guide plate on the cover board vertical direction moves; Two slip set of rollers are installed in described upper skeleton left side, respectively adorn a slip set of rollers up and down, and upper skeleton and lower skeleton connect and compose the framed structure that relative fixed can be adjusted again; Cover plate is screwed onto on the lower skeleton, and pressing plate is arranged in the framed structure that is made of upper skeleton and lower skeleton, and this pressing plate is connected with cover plate by the bolt that passes lower skeleton, and spring housing is on the bolt between pressing plate and the lower skeleton, thus formation servo-actuated hold-down mechanism; A slip set of rollers is installed on the pressing plate, and five groups of slip set of rollers are slided on the curve slide rail; The water pipe and the cable that link to each other with ultrasonic probe are fixed on the upper skeleton.

The utility model compared with prior art, its remarkable advantage is: (1) can be according to the shape servo-actuated of curve slide rail, guarantees that ultrasonic probe is consistent with the normal direction of curve slide rail.(2) simple in structure, easy to maintenance, stable performance can reduce the degree of freedom of ultrasonic scanning system, thereby reduce cost.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 2 is the synoptic diagram of ultrasonic probe hunting gear of the present utility model at curve slide rail diverse location.

Embodiment

In conjunction with Fig. 1 and Fig. 2, the utility model ultrasonic probe hunting gear, comprise upper skeleton 1, lower skeleton 2, pressing plate 3, cover plate 4, spring 5, guide plate 6, slide block 7, probe fixed mount 8, slip set of rollers 9, ultrasonic probe 11 links to each other with slide block 7 by probe fixed mount 8, this probe fixed mount 8 can be at slide block 7 upper angle directional trims, this slide block 7 moves along guide plate 6 horizontal directions, and this guide plate 6 vertical direction on cover plate 4 moves; Two slip set of rollers 9-1 are installed in described upper skeleton 1 left side, respectively adorn slip set of rollers 9-2, a 9-3 up and down, and upper skeleton 1 and lower skeleton 2 connect and compose the framed structure that relative fixed can be adjusted again; Cover plate 4 is screwed onto on the lower skeleton 2, pressing plate 3 is arranged in the framed structure that is made of upper skeleton 1 and lower skeleton 2, this pressing plate 3 is connected with cover plate 4 by the bolt that passes lower skeleton 2, and spring 5 is enclosed within on the bolt between pressing plate 3 and the lower skeleton 2, thereby constitutes the servo-actuated hold-down mechanism.The bolt number is chosen as required.A slip set of rollers 9-4 is installed on the pressing plate 3, and five groups of slip set of rollers 9-1,9-2,9-3,9-4 slide on curve slide rail 10; The water pipe and the cable 12 that link to each other with ultrasonic probe 11 are fixed on the upper skeleton 1.

Ultrasonic probe hunting gear of the present utility model is provided with the waist hole on lower skeleton 2, upper skeleton 1 is connected by the screw that passes the waist hole with lower skeleton 2.Slide block 7 is an oat tail groove structure.Every group of slip set of rollers 9-1,9-2,9-3,9-4 comprise a framework and two rollers, and two rollers are connected with framework by bearing pin respectively, and these two rollers are the deep groove ball bearing of band dust cap.Whole like this servo-actuated stationary installation all is that line contacts with four faces of curve slide rail 10, has reduced the friction force of device on curve slide rail 10.
