Description

Technical Field

[0001] The utility model relates to the field of ultrasonic detection, in particular to a clamping device and an ultrasonic detection system. Background Art

[0002] The combination of ultrasonic phased array technology and water-coupled platform is affected by many factors such as environmental parameters and material properties. Therefore, it has high requirements for detection accuracy and requires accurate calibration and calibration. In terms of water-coupled ultrasonic testing, the detection objects of water-coupled ultrasound are still some large components, and the water spray coupling detection method is rarely used in practice. For some smaller workpieces and complex parts, the detection method is still mainly based on water immersion, and it is still mainly based on ordinary ultrasonic detection probes. Full water immersion testing requires the object to be fully immersed in water. The working environment is complex and the operation is difficult, requiring operators with professional skills.

In addition, the current clamp can only hold one type of ultrasonic testing probe. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.

[0031] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0033] The combination of ultrasonic phased array technology and water-coupled platform is affected by many factors such as environmental parameters and material properties. Therefore, it has high requirements for detection accuracy and requires accurate calibration and calibration. In terms of water-coupled ultrasonic testing, the detection objects of water-coupled ultrasound are still some large components, and the water spray coupling detection method is rarely used in practice. For some smaller workpieces and complex parts, the detection method is still mainly based on water immersion, and it is still mainly based on ordinary ultrasonic detection probe detection. Full water immersion detection requires the object to be fully immersed in water. The working environment is complex and the operation is difficult. It requires operators with professional skills. However, the fixture of the ultrasonic detection probe in the current ultrasonic detection system is easy to damage the probe when the fixture clamps the probe close to the test block for detection when the test block is not placed flat, affecting the accuracy of the detection. And the current fixture can only clamp one type of ultrasonic detection probe.

[0034] Based on this, see Figure 1 and Figure 2 The clamping device 100 provided in the embodiment of the utility model can effectively solve the above-mentioned technical problems. The clamping device 100 can prevent the clamped probe from being damaged, and the clamping device 100 can clamp ultrasonic detection probes 200 of various sizes. The clamping device 100 is applied to an ultrasonic detection system 1000, and the ultrasonic detection system 1000 having the clamping device 100 also has the same functions as above.

In addition, the ultrasonic detection system 1000 may also include a moving device, such as a manipulator, etc., the end of the manipulator is connected to the clamping device 100, and the manipulator drives the clamping device 100 to move. The manipulator can drive the clamping device 100 clamping the ultrasonic detection probe 200 to move closer to or away from the test block to be detected. At the same time, when the test block to be detected has an inclined plane, the ultrasonic detection probe 200 can also be kept level with the test block to improve the accuracy of the detection by adjusting the angle of the end of the manipulator. Of course, the ultrasonic detection system 1000 may also include other structural parts, such as a control module, etc., to realize the various functions of the ultrasonic detection system 1000, which are not limited here.

[0036] The structure of the clamping device 100 is described in detail below.

[0037] Figure 2 It is a schematic diagram of a first viewing angle of a clamping device 100 provided in an embodiment of the present utility model; Figure 3This is a schematic diagram of a second viewing angle of the clamping device 100 provided in an embodiment of the present invention. Figure 2 and Figure 3 The clamping device 100 in the embodiment of the utility model includes a moving component 110, a first clamping component 120 and a second clamping component 130. The first clamping component 120 includes a first upper clamping plate 121, a first lower clamping plate 122 and a first elastic buffer 123. The first upper clamping plate 121 is movably connected to the moving component 110; one end of the first elastic buffer 123 is connected to the first upper clamping plate 121, and the other end of the first elastic buffer 123 is connected to the first lower clamping plate 122; the second clamping component 130 includes a second The upper clamping plate 131, the second lower clamping plate 132 and the second elastic buffer 133, the second upper clamping plate 131 is movably connected to the moving assembly 110; one end of the second elastic buffer 133 is connected to the second upper clamping plate 131, and the other end of the second elastic buffer 133 is connected to the second lower clamping plate 132; the first clamping assembly 120 and the second clamping assembly 130 can be relatively close to or far away from each other on the moving assembly 110, and the first clamping assembly 120 and the second clamping assembly 130 are used together to clamp or release the ultrasonic detection probe 200. The moving assembly 110 can adjust the relative position between the first clamping assembly 120 and the second clamping assembly 130, and change the spacing between the first clamping assembly 120 and the second clamping assembly 130, so that the clamping device 100 can clamp ultrasonic detection probes 200 of different sizes. The upper and lower clamps are connected by an elastic buffer so that when the ultrasonic detection probe 200 and the clamping device 100 are collided, the elastic buffer will retract to a safe position to ensure that the ultrasonic detection probe 200 will not be damaged by the pressure at the end of a moving device such as a robotic arm that moves with the clamping device 100.

[0038] By setting the moving assembly 110, the first clamping assembly 120 and the second clamping assembly 130 are both movably connected to the moving assembly 110, and the relative position between the first clamping assembly 120 and the second clamping assembly 130 can be adjusted. The spacing between the first clamping assembly 120 and the second clamping assembly 130 can be adjusted according to the size of the ultrasonic detection probe 200 to be clamped, so as to clamp ultrasonic detection probes 200 of various sizes and types. By dividing the first clamping assembly 120 and the second clamping assembly 130 into two parts, and connecting the upper and lower clamping plates by an elastic buffer, when the first clamping assembly 120 and the second clamping assembly 130 jointly clamp the ultrasonic detection probe 200 to contact the test block to be detected, a buffering effect is played, thereby preventing the ultrasonic detection probe 200 from being damaged.

[0039] In order to enable the clamping device 100 to fix the ultrasonic detection probe 200 horizontally when clamping it, and to prevent the ultrasonic detection probe 200 from colliding with the first clamping assembly 120 and the second clamping assembly 130 and causing damage when the clamping device 100 is adjusted in angle, please continue to refer to Figure 2 and Figure 3 In this embodiment, spring racks 140 are provided on the first lower clamping plate 122 and the second lower clamping plate 132. The ultrasonic detection probe 200 is in contact and connected with the first lower clamping plate 122 and the second lower clamping plate 132 through the spring rack 140. When the clamping device 100 is rotated to adjust the angle between the ultrasonic detection probe 200 and the test block to be detected, the spring rack 140 has elastic force and a buffering effect, which can prevent the ultrasonic detection probe 200 from colliding with the first clamping assembly 120 and the second clamping assembly 130 and damaging the ultrasonic detection probe 200. And because the spring rack 140 has a telescopic function, the spring rack 140 can be provided to fix ultrasonic detection probes 200 of different lengths, which can ensure that the ultrasonic detection probe 200 and the clamping device 100 are fixed horizontally.

[0040] The number of spring racks 140 in this embodiment is multiple, and the multiple spring racks 140 are arranged at intervals at one end of the first lower clamping plate 122 or the second lower clamping plate 132 away from the moving assembly 110.

Of course, it is also possible to arrange one, two, three or more spring racks 140 on the first lower clamping plate 122, and one, two, three or more spring racks 140 on the second lower clamping plate 132. The number of spring racks 140 to be arranged is determined according to actual production and use requirements, and is not limited here.

[0041] In order to prevent the clamping device 100 from moving under the drive of the manipulator and accidentally contacting the test block to be tested, causing collision and damage, considering the working characteristics of the manipulator when pressing down, the first elastic buffer 123 in this embodiment is a spring buffer; and / or the second elastic buffer 133 is a spring buffer. Of course, the first elastic buffer 123 and the second elastic buffer 133 can also use rubber shock absorbers, polyurethane buffers and other buffers, as long as they can play a buffering effect when the ultrasonic detection probe 200 accidentally contacts the test block to be tested, and prevent the ultrasonic detection probe 200 from being damaged. The specific type of elastic buffer to be used is determined according to actual conditions and is not limited here.
