Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

the first embodiment is as follows:

as a preferred embodiment provided by the present invention, the present invention provides an ultrasonic detection mechanism 300 of a flaw detector, as shown in fig. 1, the ultrasonic detection mechanism 300 mainly includes two parts, i.e. a probe assembly 200 and a quick release assembly 100, wherein the probe assembly 200 has a probe for flaw detection, and the probe assembly 200 and the end of the mechanical arm of the flaw detector can be stably connected through the quick release assembly 100, and on the other hand, the assembly, disassembly and maintenance of the probe assembly 200 can be facilitated.

Specifically, the quick release assembly 100 includes a base 1, a quick release member 2 and a locking member 3. Wherein, the bottom of base 1 need form firm the connection with the arm end of flaw detector when using, and the connection between the two can be realized through the undetachable mode of modes such as welding, certainly also can realize through removable modes such as threaded connection. Preferably, the bottom end of the base 1 is set to be the flange structure to realize the end-to-end connection of the base 1 and the mechanical arm in the embodiment, so that the stability of the end-to-end connection of the base 1 and the mechanical arm can be ensured, the base 1 is prevented from shaking or even falling off in the flaw detection process, and the base 1 and the end of the mechanical arm can be conveniently assembled and disassembled for maintenance after the flaw detector is used for a long time.

In this embodiment, the other part of the quick release assembly 100, i.e. the quick release member 2, is connected to the probe assembly at one end in a stable manner, and the connection between the two parts may be various connections such as the base 1 and the end of the robot arm.

After the quick release part 2 and the base 1 are respectively connected with the probe assembly 200 and the tail end of the mechanical arm, which correspond to each other, only the other end of the quick release part 2 needs to be inserted into the slot of the mounting slot 11 arranged at the top end of the base 1, and the other end can be slidably inserted into the mounting slot 11, so that the quick release part 2 can obtain the pushing force entering the mounting slot 11 and the pulling force leaving the mounting slot 11 under the action of external force (for example, a human hand provides the pushing force or the pulling force to the quick release part 2 through the probe assembly 200).

As shown in fig. 2 to 5, a through cavity 12 is opened on the wall of the mounting groove 11, and a locking member 3 having a rotating shaft 31, a pressing plate 32 and an elastic element 33 is provided on the through cavity 12, and a locking groove 21 matching with the through cavity 12 is provided on the outer wall of the quick release member 2. Therefore, when the quick release member 2 is pushed to enter the mounting groove 11 and contact the pressing plate 32, the pressing plate 32 is pivoted on the rotating shaft 31 fixed in the through cavity 12, so that the pressing plate 32 can overcome the elastic force of the elastic element 33 arranged on the mounting groove 11 and rotate along with the further insertion of the quick release member 2 until the bottom of the clamping groove 21 on the quick release member 2 is staggered with the bottom of the pressing plate 32, and at the moment, the pressing plate 32 only receives the restoring force exerted by the elastic element 33 and rotates under the action of the restoring force until the bottom of the pressing plate 32 is in clamping fit with the clamping groove 21, so that the quick release member 2 is stably connected to the base 1, and the stable connection of the probe assembly 200 and the tail end of the mechanical arm is realized. Of course, in order to improve the stable connection between the rotating shaft 31 and the through cavity 12, as shown in fig. 8, a retaining ring 311 may be added to the installation of the rotating shaft 31. The elastic element 33 is a torsion spring in this embodiment, but may be other elastic bodies such as a spring.

When the probe assembly 200 needs to be disassembled from the tail end of the mechanical arm to replace or maintain the probe assembly 200, only a pressing force needs to be applied on the pressing plate 32 to drive the pressing plate 32 to rotate, so that the bottom of the pressing plate 32 can push the clamping groove 21 to move towards the bottom of the mounting groove 11 until the bottom of the pressing plate 32 moves out of the clamping groove 21, after the bottom of the pressing plate 32 moves out of the clamping groove 21, the quick-release part 2 can be pulled out of the mounting groove 11 by applying a pulling force to the probe assembly 200, so that the quick-release part 2 is quickly separated from the base 1, and the quick separation of the probe assembly 200 and the tail end of the mechanical arm is realized, so that the assembly and disassembly operation efficiency is improved.

In order to prevent the buckling member 3 from failing due to improper operation or use during the assembling and disassembling process, a limiting member may be disposed, for example, to limit each component of the buckling member 3, especially the pressing plate 32, so that the component cannot be separated from the preset movable range. For example, the wall thickness between the upper end surface of the mounting groove 11 and the wall of the through cavity 12 can be increased to facilitate the arrangement of a limiting groove thereon, so that the end of the pressing plate 32 can be slidably arranged in the limiting groove.

In addition, the installation groove 11 and the quick-release piece 2 are arranged in shapes, such as asymmetrical arrangement of length and width, so that the guide and positioning during installation are facilitated, and quick installation is realized. Of course, this can also be achieved by providing a guide between the mounting groove 11 and the quick release 2.

In order to further improve the connection stability between the quick release member 2 and the base 1, for example, as shown in fig. 2, fig. 6 and fig. 7, an elastic adjusting member 4 may be further disposed between the quick release member 2 and the bottom of the mounting groove 11, and when the clamping groove 21 is clamped with the bottom of the pressing plate 32, the elastic adjusting member 4 may provide a pushing force to the clamping groove 21 opposite to the bottom acting force of the pressing plate 32, so that the bottom of the pressing plate 32 is in abutting engagement with the clamping groove 21, and thus, the quick release member 2 may be more stably fixed on the base 1 under two opposite acting forces related to the moving direction thereof.

The elastic adjusting member 4 may be disposed in various manners, and in order to fully utilize the inner space of the mounting groove 11, for example, the elastic adjusting member 4 may be disposed to include a pillar 41 and a compression spring 42, and an end surface of the other end of the quick release member 2 is recessed to form the groove 22, and one end of the pillar 41 is slidably inserted into the groove 22 and connected to the bottom of the groove 22 by the compression spring 42. Thus, as the quick release member 2 enters the mounting groove 11, the elastic force generated by the deformation of the compressed spring 42 under pressure gradually pushes the other end of the strut 41 to move towards the bottom of the mounting groove 11 until the elastic force abuts against the bottom of the mounting groove 11; on the other hand, after the bottom of the pressing plate 32 is clamped with the clamping groove 21, the elastic force pushes the quick-release part 2 to move in the direction away from the bottom of the mounting groove 11 through the groove bottom of the groove 22, so that a pulling force opposite to the pressing force of the pressing plate 32 is formed on the clamping groove 21, and the clamping groove 21 is abutted against the bottom of the pressing plate 32.

In order to make the compression spring 42 apply a uniform force to the pillar 41 and the bottom of the groove 22, it is preferable that the pillar 41 is formed in a barrel shape, and correspondingly, the groove 22 is formed in a ring shape, and the compression spring 42 is sleeved on the inner wall 226 of the groove 22. In this way, when the quick release member 2 is mounted and removed, the external force applied to the quick release member 2 can reduce the shaking of each component during the mounting and removing process by the internal forces of the compression spring 42, the support 41 and the groove 22, so that on one hand, the damage of each component can be avoided, on the other hand, the mounting and removing operation can be conveniently performed by a person, and the mounting and removing process of the probe assembly 200 is easy and safe.

Further, the groove 22 may be configured as an annular step structure, and the groove 22 has a first annular outer wall 221, a first mesa 222, a second annular outer wall 223, a second mesa 224 and a third annular outer wall 225 which are sequentially connected in the direction from the notch to the groove bottom. Wherein, a first cavity 227 for the compression spring 42 and the end of the support 41 to slide is formed between the third annular outer wall 225 and the inner wall 226 of the groove 22, the limiting ring 43 is arranged on the outer wall of the support 41, the annular cap 44 is arranged on the first table surface 222, a second cavity 228 for the limiting ring 43 to slide is enclosed between the annular cap 44 and the second annular outer wall 223, the second table surface 224 and the outer wall of the support 41, and the other end of the support 41 can slidably extend out of the annular cap 44.

In the above arrangement, by limiting the movement range of the limiting ring 43 on the strut 41 in the second cavity 228 and combining the assembling relationship of other components, on one hand, the strut 41, the compression spring 42 and the quick release member 2 can be connected into a whole, so that the assembling and disassembling links of the strut 41, the compression spring 42 and the quick release member 2 in the assembling and disassembling process of the probe assembly 200 can be omitted, thereby further improving the working efficiency, and the connection tightness among the components of the quick release assembly 100 can be improved to enhance the integrity of the quick release assembly 100, thereby further improving the stability and safety of the quick release assembly 100; on the other hand, the moving track range of the support column 41 and the quick release member 2 in the assembling and disassembling process can be indirectly limited, so that the connection position of each component in the quick release assembly 100 can form good buffer, thereby protecting each component in the quick release assembly 100 on the one hand and protecting the tested piece on the other hand. Thus, the stability of the performance of the quick release assembly 100 is improved, the service life of the quick release assembly 100 is prolonged, and the integrity of a tested piece is ensured.

To facilitate inspection and maintenance of the post 41, compression spring 42, and recess 22, the cap may be removably coupled to the first table 222, for example. Preferably, threads are provided on the first annular outer wall 221, and the annular cap 44 is screwed onto the first table 222. The shape of the two ends of the annular cap 44 can be adjusted according to specific requirements. For example, the end surface of the bottom end of the annular cap 44 may be made flush with the notch of the groove 22, while the top end of the annular cap 44 protrudes along the second annular outer wall 223 to finally form the annular cap 44 into a stepped shape. Of course, the top end of the annular cap 44 extending along the second annular outer wall 223 can limit the position of the ring 43, so as to achieve a desired position state of each relevant component in the quick release assembly 100 during the assembly and disassembly process, and on the other hand, the cap is conveniently limited to facilitate the assembly of the cap and further reduce the shaking of the cap caused by collision.

The retainer ring 43 is a part which frequently collides during the assembly and disassembly of the quick release assembly 100, and for the convenience of maintenance and the enhancement of the service life thereof, the connection between the retainer ring 43 and the support 41 may be made in a detachable manner, and the retainer ring 43 itself may have a certain elasticity. Preferably, the outer wall of the pillar 41 may be provided with an annular recess 411, and the limiting ring 43 may be a snap spring sleeved on the annular recess 411, so that the above effects are achieved and the cost is reduced.

In addition, on the basis of ensuring the mechanical performance (such as strength and rigidity) of the quick release part 2, the weight of the quick release part 2 can be controlled by arranging the lightening grooves 23, so that the collision of the quick release part 2 caused by mass inertia is reduced, and further collision avoidance is performed on each part in the quick release assembly 100.

Example two:

this embodiment is provided as another preferred embodiment of the present invention, which provides an ultrasonic detection mechanism 300 for a flaw detector, as shown in fig. 9 and 10, the ultrasonic detection mechanism 300 optimizes the probe assembly 200 in addition to the quick release assembly 100 of the first embodiment, so that the ultrasonic detection mechanism 300 can perform better flaw detection on a magnetic metal piece.

Therefore, on one hand, the mechanical arm can drive the base 5 to move so as to realize the movement of the electromagnetic ultrasonic probe 6 fixed on the base 5, so that the electromagnetic ultrasonic probe 6 can move on the surface of the detected magnetic metal piece along a detection route in the detection process; on the other hand, after the electromagnetic ultrasonic probe 6 moves to the target position, the ferromagnetism generated by the electromagnetic ultrasonic probe 6 due to the self-working can cause the electromagnetic ultrasonic probe 6 to change the posture of the electromagnetic ultrasonic probe 6 along with the radian of the surface of the measured ferromagnetic metal piece, so that the axial direction of the electromagnetic ultrasonic probe 6 is finally vertical to the surface of the measured ferromagnetic metal piece, and the electromagnetic ultrasonic probe 6 is connected with the base 5 through the universal connecting piece 7, thereby ensuring that the steering of the electromagnetic ultrasonic probe 6 is not blocked in the posture adjustment process, realizing the self-adaptive compensation of the electromagnetic ultrasonic probe 6 on the posture deviation of the surface of the measured ferromagnetic metal piece with different planeness in the detection process, reducing the adverse effect of the motion error of the ultrasonic flaw detector on the detection precision, and ensuring that the axial direction of the electromagnetic ultrasonic probe 6 is always vertical to the surface of the measured ferromagnetic metal piece in the moving process, the accuracy of the ultrasonic flaw detector for the detection results of the magnetic metal pieces in different shapes is improved.

The quick release member 2 in this embodiment is connected to the probe assembly 200 by a screw thread. Namely, a plurality of mounting holes 51 are formed on the base 5 of the probe assembly 200, and the quick-release member 2 and the probe assembly 200 can be detachably and stably connected only by the screws 9, the gaskets 91 and corresponding tools during mounting.

The universal joint 7 is used as a device for connecting the electromagnetic ultrasonic probe 6, and the structure of the universal joint can be diversified after the requirement of the rotation angle range of the electromagnetic ultrasonic probe 6 is ensured. Preferably, in order to reduce the cost and achieve simple installation of a plurality of electromagnetic ultrasonic probes 6 on one base 5, the universal joint 7 used in the present embodiment includes a bearing seat 71 and a ball bearing 72.

In order to improve the detection efficiency of the ultrasonic flaw detector, as shown in fig. 12, preferably, more than one electromagnetic ultrasonic probe 6 may be disposed on the base 5, so as to realize multi-point detection and improve the overall detection efficiency. In order to improve the detection efficiency and the accuracy of the detection result of the ultrasonic flaw detector, each electromagnetic ultrasonic probe 6 can be matched with one universal connecting piece 7, the distance between two adjacent universal connecting pieces 7 on the base 5 is ensured, so that the two electromagnetic ultrasonic probes 6 corresponding to the two universal connecting pieces 7 are in non-contact in the rotation process, the collision among the electromagnetic ultrasonic probes 6 is avoided, on one hand, the damage rate of the electromagnetic ultrasonic probes 6 in the detection process can be reduced, and on the other hand, the accuracy of the detection result can be enhanced.

Preferably, as shown in fig. 13, a threaded hole 61 may be provided on the electromagnetic ultrasonic probe 6, and the bearing end 722 of the ball bearing 72 is fixed in the threaded hole 61 by a screw connection. It is understood that other detachable connections may be used in other embodiments.

In order to protect the electromagnetic ultrasonic probe 6, a flexible protective layer may be provided on the outer peripheral wall of the electromagnetic ultrasonic probe 6.

Of course, in order to adjust the overall posture of the probe assembly 200, for example, a plurality of distance measuring sensors, such as laser distance measuring sensors, may be disposed on the base 5 at intervals, so that the ultrasonic flaw detector may monitor the position and posture of the probe assembly 200 in time, and the position and posture of the probe assembly 200 may be adjusted by the mechanical arm. Of course, the position and the posture can be adjusted to enable the ultrasonic detection mechanism 300 to keep the optimal position with the magnetic metal part to be detected all the time in the process of continuously detecting the ultrasonic detection mechanism 300, so as to reduce the collision and to perform anti-collision protection on each component in the ultrasonic detection mechanism 300 and the magnetic metal part to be detected.

In addition, as shown in fig. 9 to 11, a photoelectric switch 8 is further provided in the ultrasonic detection mechanism 300 so as to monitor the positional relationship between the base 5 and the base 1.
