Description

Technical Field

[0001] This utility model relates to an auxiliary device for ultrasonic flaw detection, and more particularly to a probe coupling auxiliary device that adaptively conforms to the workpiece. Background Technology

[0002] Ultrasonic scanners are widely used for scanning and flaw detection of flat sheet metal. They include a probe coupling auxiliary device, or probe holder, for mounting the ultrasonic scanning probe. Existing ultrasonic scanners typically have a probe coupling device body that is adapted to the probe, connected to components such as an operating handle. During scanning, the inspector operates the scanning probe via the handle to press the probe-carrying coupling device body against the workpiece surface and move it across it, allowing the probe to perform ultrasonic scanning of the sheet metal. To achieve tight coupling between the probe and the inspected workpiece and ensure scanning effectiveness, a tension spring or torsion spring is generally installed between the coupling device body and the handle to press the probe-carrying auxiliary device against the workpiece surface, thus achieving tight coupling and ensuring scanning quality. Although tension springs or torsion springs can tightly couple the probe to the workpiece through their elastic force, in order to install tension springs or torsion springs, multiple parts for installing tension springs or torsion springs need to be set on the coupling device body and handle, etc., which makes the structural design cumbersome, and the trivial parts are easy to be damaged or lost. Therefore, a probe coupling auxiliary device with a more streamlined structure needs to be designed to solve the above problems. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a probe coupling auxiliary device that achieves adsorption coupling through a magnetic wheel and has a simpler and more compact structure for adaptively fitting the workpiece.

[0004] The present invention discloses an adaptive probe coupling auxiliary device for fitting workpieces, comprising a coupling device body adapted to the probe, magnetic wheel assemblies fixed on the left and right sides of the coupling device body, the magnetic wheel assembly comprising a base plate fixedly connected to the coupling device body, a mounting plate fixedly disposed at the bottom end of the base plate and perpendicular to the base plate, and a magnetic roller with its main shaft disposed on the mounting plate. The surface of the base plate is provided with a strip-shaped guide hole, and the end of the connecting bolt passes through the strip-shaped guide hole and is threadedly connected to the coupling device body.

[0005] The advantage of this adaptive workpiece-fitting probe coupling auxiliary device is that magnetic wheel assemblies are provided on both the left and right sides of the coupling device body. The magnetic wheel assembly includes a base plate, which is fixed to the surface of the coupling device body by connecting bolts. A magnetic roller is mounted on the bottom end of the base plate through a mounting plate. The setting of the magnetic roller allows the probe coupling auxiliary device to achieve tight coupling between the probe and the iron plate without the need for springs or compression springs. Compared with existing probe coupling auxiliary devices, it has relatively fewer parts for mounting the magnetic roller, so the structure is simpler and more compact, and it is also more convenient to use.

[0006] Furthermore, the adaptive probe coupling auxiliary device of this utility model includes a U-shaped positioning frame, a U-shaped base at the rear end of the U-shaped positioning frame, and a baffle on the front end of the U-shaped positioning frame. The U-shaped positioning frame, the U-shaped base, and the baffle surround and form a probe groove.

[0007] The coupling device body, consisting of a U-shaped positioning frame, a U-shaped base, and a baffle, enables the installation of the probe, while its structure is simple and lightweight.

[0008] Furthermore, in the adaptive workpiece-fitting probe coupling auxiliary device of this utility model, the U-shaped base includes a connecting arm and side arms at both ends of the connecting arm, and the connecting arm is provided with threaded holes for threaded connection with the tightening bolt.

[0009] The setting of the tightening bolt and threaded hole achieves the purpose of tightening the probe against the baffle, thereby fixing the probe so that it can stably inspect the plate during movement.

[0010] Furthermore, in the adaptive workpiece-fitting probe coupling auxiliary device of this utility model, the U-shaped base includes a connecting arm and side arms at both ends of the connecting arm, and the inner side of the connecting arm is provided with a positioning groove for installing a spring.

[0011] The positioning groove and spring allow the operator to press the probe firmly against the baffle using the spring.

[0012] Furthermore, in the adaptive workpiece-fitting probe coupling auxiliary device of this utility model, the surface of the U-shaped base is provided with a water inlet hole, and the inner side of the U-shaped base is provided with a water outlet groove communicating with the water inlet hole.

[0013] The water inlet and the connected water outlet allow operators to supply water to the probe through the water inlet and the water outlet, thereby further improving the coupling between the probe and the plate.

[0014] Furthermore, the adaptive probe coupling auxiliary device for fitting the workpiece of this utility model also includes a baffle plate. The bottom wall of the water outlet tank is provided with a strip-shaped inlet and outlet hole adapted to the baffle plate, and the baffle plate is disposed in the strip-shaped inlet and outlet hole.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] Example 1: See Figures 1 to 8 The adaptive workpiece-fitting probe coupling auxiliary device of this embodiment includes a coupling device body 1 adapted to the probe. Magnetic wheel assemblies 2 are fixed on the left and right sides of the coupling device body. The magnetic wheel assembly includes a base plate 3 fixedly connected to the coupling device body, a mounting plate 4 fixedly disposed at the bottom of the base plate and perpendicular to the base plate, and a magnetic roller 5 with its main shaft disposed on the mounting plate. A strip-shaped guide hole 6 is opened on the surface of the base plate, and the end of a connecting bolt 7 passes through the strip-shaped guide hole and is threadedly connected to the coupling device body.

[0033] The adaptive workpiece fitting device has magnetic wheel assemblies on both the left and right sides of its coupling device body. The magnetic wheel assembly includes a base plate, which is fixed to the surface of the coupling device body by connecting bolts. A magnetic roller is mounted on the bottom of the base plate by a mounting plate. The magnetic roller allows the probe coupling auxiliary device to achieve tight coupling between the probe and the iron plate without the need for springs or compression springs. Compared with existing probe coupling auxiliary devices, it has relatively fewer parts for mounting the magnetic roller, so the structure is simpler and more compact, and it is also more convenient to use.

[0034] The coupling device body is used to install the probe 8, and it is provided with a probe groove 9 that is compatible with the probe, and the surface has a cable connection port 10 for cable routing.

[0035] The magnetic roller assembly is used to attach the coupling device body and its probe to the surface of the metal plate. During scanning, its magnetic roller is located above the workpiece surface. The probe is pressed against the plate surface by the magnetic roller's adsorption force. At this time, there is a certain gap between the magnetic roller and the plate surface to ensure that the probe can be fully coupled with the plate.

[0036] The base plate is used to fix the mounting plate and magnetic roller. It is provided with a vertically extending strip-shaped guide hole. The connecting bolt passes through the strip-shaped guide hole and is threadedly connected to the coupling device body.

[0037] The design of the guide holes and connecting bolts allows operators to adjust the height of the substrate to accommodate different probe models, ensuring that the end face of the probe is always in contact with the substrate surface, thereby improving the versatility of the probe coupling auxiliary device.

[0038] During adjustment, the operator first loosens the connecting bolts, then manually moves the substrate. During the movement, the connecting bolts move relative to the strip-shaped guide holes on the surface of the substrate until the substrate moves to the predetermined height. Then, the connecting bolts are tightened to fix the substrate to the surface of the coupling device body, thereby achieving the adjustment of the height of the substrate and the magnetic roller.

[0039] The mounting plate is used to mount the magnetic roller. It is perpendicular to the base plate and has through holes or grooves on its surface for mounting the magnetic roller spindle. The magnetic roller spindle can be fixed in the through holes or grooves on the surface of the mounting plate by means of interference fit or key connection.

[0040] The magnetic roller is a commercially available component containing magnetic material to attract iron plates. Its spindle end is mounted on a mounting plate.

[0041] During scanning, the operator places the probe coupling auxiliary device on the surface of the iron plate. The magnetic roller's attraction to the plate presses the probe firmly against the plate surface. The operator can then move the probe coupling auxiliary device on the plate surface using a handle or other components. During the movement, the probe sends ultrasonic waves and transmits the received echoes to the host computer via a cable, thus completing the scanning.

[0042] Preferably, the coupling device body includes a U-shaped positioning frame 11, a U-shaped base 12 is provided at the rear end of the U-shaped positioning frame, and a baffle 13 is provided on the front end surface of the U-shaped positioning frame. The U-shaped positioning frame, the U-shaped base and the baffle surround to form a probe groove.

[0043] The coupling device body, consisting of a U-shaped positioning frame, a U-shaped base, and a baffle, enables the installation of the probe, while its structure is simple and lightweight.

[0044] During installation, the operator inserts the probe from the lower side of the opening end of the U-shaped positioning frame into the probe groove formed by the U-shaped positioning frame, the U-shaped base, and the baffle, until the top surface of the probe contacts the top wall of the U-shaped positioning frame. At this time, the connector connecting the probe and the host computer is located in the space between the U-shaped positioning frame and the U-shaped base, i.e., the cable connection port.

[0045] Preferably, the U-shaped base includes a connecting arm 14 and side arms 15 at both ends of the connecting arm, and the connecting arm is provided with a threaded hole 17 for threaded connection with a tightening bolt (not shown in the figure).

[0046] The setting of the tightening bolt and threaded hole achieves the purpose of tightening the probe against the baffle, thereby fixing the probe so that it can stably inspect the plate during movement.

[0047] In this embodiment, the U-shaped positioning frame and the U-shaped base are integrally formed, and the baffle is fixed to the front side of the U-shaped positioning frame with screws. Threaded holes are provided on the connecting arm directly opposite the baffle. During installation, after the top of the probe contacts the top wall of the U-shaped positioning frame, the operator rotates the tightening bolt until its end contacts the probe and presses it firmly against the baffle.

[0048] Preferably, the U-shaped base includes a connecting arm and side arms at both ends of the connecting arm, and the inner side of the connecting arm is provided with a positioning groove 18 for installing a spring.

[0049] The positioning groove and spring allow the operator to press the probe firmly against the baffle using the spring.

[0050] Specifically, one end of the spring can be fixed in the positioning groove, and the other end can directly contact the probe or connect to a connector with a smooth end face. The end face of the connector can be spherical or curved. During installation, the side of the probe can press the spring or connector into the positioning groove. The spring in the positioning groove can press the connector against the probe surface and press the probe against the baffle. The spring and connector can also be integrated into a cylindrical housing. The cylindrical housing is fixed in the positioning groove, and one end of the cylindrical housing has an opening smaller than the connector, such as a steel ball. The spring is located between the connector and the cylindrical housing.

[0051] Preferably, the surface of the U-shaped base is provided with a water inlet hole 19, and the inner side of the U-shaped base is provided with a water outlet groove 20 communicating with the water inlet hole.

[0052] The water inlet and the connected water outlet allow operators to supply water to the probe through the water inlet and the water outlet, thereby further improving the coupling between the probe and the plate.

[0053] In this embodiment, water inlets are provided on both the left and right side arms of the U-shaped base. Water pipe connectors 21 are installed at the water inlets. The water outlet is located below the water inlets. One end of the water outlet is connected to the bottom end of the water inlet, and the other end extends to the side of the U-shaped base or U-shaped positioning frame and is connected to the baffle. The water outlet of the water outlet is located on the inner side of the connecting arm. During operation, external water is input into the water outlet through the water pipe connector and the water inlet, and then output to the probe through the opening of the water outlet to make it tightly coupled with the plate.

[0054] Example 2: See Figures 9 to 13 The adaptive workpiece-fitting probe coupling auxiliary device of this embodiment has been improved based on the first embodiment. Specifically, the adaptive workpiece-fitting probe coupling auxiliary device also includes a baffle plate 24. The bottom wall of the water outlet trough 20 is provided with a strip-shaped inlet and outlet hole 25 adapted to the baffle plate, and the baffle plate is disposed in the strip-shaped inlet and outlet hole.

[0055] The baffle plate and strip-shaped inlet / outlet holes enable control of water flow to accommodate different probe models.

[0056] Because different probe models have different widths, the distance between their sides and the water outlet varies. Additionally, different materials and probes may require different amounts of water. Therefore, a baffle plate is installed at the water outlet of the water outlet to adjust the water flow, thereby achieving adaptation to different probes and materials.

[0057] In this embodiment, guide grooves 22 with bottom ends communicating with the strip-shaped inlet / outlet holes are provided on both the front and rear sides of the water outlet trough. One guide groove is located on the rear side of the water outlet trough of the side arm 15, and the other guide groove is located on the inner side of the baffle 13, i.e., the front side of the water outlet trough. The baffle passes through the strip-shaped inlet / outlet hole, with both ends located in the guide grooves and its bottom end located above the bottom end of the magnetic roller. The baffle can be made of plastic, and its thickness is slightly greater than the width of the strip-shaped inlet / outlet hole, so that the baffle can be fixed at a fixed height by a tight fit. In addition, the baffle can also be locked by setting locking screws on the inner side of the connecting arm, with the ends of which pass through the guide grooves or the strip-shaped inlet / outlet holes 25. In use, the operator can adjust the size of the water outlet trough opening by adjusting the height of the baffle, thereby adjusting the water output. For easy adjustment, an operating hole 23 can also be provided at the bottom of the baffle, and a scale can be provided on the surface of the baffle to achieve positioning and adjustment of the baffle height.
