Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic testing equipment technology, specifically relating to a clamping mechanism for a rotating head used in ultrasonic testing. Background Technology

[0002] In the field of modern industrial inspection, ultrasonic testing, with its non-destructive, efficient, and precise characteristics, is widely used in material defect detection, thickness measurement, and other scenarios. Among these applications, the rotating head, as a key component of ultrasonic testing equipment, directly affects the accuracy and efficiency of the test results due to its installation stability and adjustment flexibility.

[0003] Traditional ultrasonic testing rotating head clamping mechanisms mostly use fixed brackets or simple bolt fastening methods. However, bolt fastening is not only cumbersome and time-consuming, but also prone to thread wear after repeated disassembly and assembly, leading to decreased clamping stability and the risk of the rotating head loosening or even falling off. This seriously affects the safety and reliability of the testing work, and this phenomenon has become a problem that urgently needs to be solved by people in this field. Utility Model Content

[0006] This utility model further explains that the connecting block has two sets of slots on the side near the clamping block, and the clamping block has two sets of matching blocks on the side.

[0007] This utility model further explains that the connecting block has two sets of cavities for the sliding of the locking rod.

[0008] This utility model further illustrates that a tension spring connects the lever and the cavity, and a support block is installed on one side of the connecting block.

[0009] This utility model further illustrates that the support block has a placement cavity for the sliding of the push rod.

[0010] This utility model further illustrates that a support spring is connected between the push rod and the placement cavity.

[0012] (1) When the rotating head of the detector needs to be clamped, the electric push rod is activated and its output end pushes the mounting block to move upward. Through the transmission of the connecting rod, the two sets of sliders move along the slide groove to the middle, driving the connecting plate and the clamping block to move to the middle at the same time, so as to achieve the fastening clamping of the rotating head. When the rotating head does not need to be clamped, the electric push rod is activated again and its output end drives the mounting block to move downward.

[0019] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4The present invention provides a technical solution: a clamping mechanism for a rotating head for ultrasonic testing, including a support base 1, a hollow support frame 2 fixedly connected to the bottom of the support base 1, an electric push rod 3 installed inside the support frame 2, two sets of fixing blocks 4 fixedly connected to the top of the support base 1, a sliding groove 5 opened on one side of the outer wall of each of the two sets of fixing blocks 4, a slider 6 slidably connected inside the sliding groove 5, a support rod 7 connected to the output end of the electric push rod 3 facing upward, an installation block 8 fixedly connected to the top of the support rod 7, a connecting rod 9 connected between the installation block 8 and the slider 6 via a rotating shaft, a connecting plate 10 fixedly connected to one side of the outer wall of the slider 6, a connecting block 11 fixedly connected to one side of the connecting plate 10, and a clamping block 12 engaged on one side of the connecting block 11;

[0021] When the rotating head of the detector needs to be clamped, the electric push rod 3 is activated, so that the output end of the electric push rod 3 pushes the mounting block 8 to move upward, so that the two sets of sliders 6 move along each set of slide grooves 5 respectively, so that the two sets of sliders 6 drive the connecting plate 10 to move towards the center at the same time, and the clamping block 12 at the connecting plate 10 can clamp the rotating head tightly.

[0022] When the rotating head of the detector does not need to be clamped, the electric push rod 3 is activated again, so that the output end of the electric push rod 3 drives the mounting block 8 to move downward, so that the two sets of sliders 6 move along each set of sliding grooves 5 to both sides of the fixed block 4, so that the two sets of sliders 6 drive the connecting plate 10 to move to both sides at the same time, and the rotating head can lose the clamping force.

[0023] A slot 13 is provided on the side of the connecting block 11 near the clamping block 12. A clamping block 14 is fixedly connected to the side of the clamping block 12 near the connecting block 11. The slot 13 and the clamping block 14 are slidably connected. Two sets of cavities 15 are provided inside the connecting block 11. A clamping rod 16 is slidably connected inside each of the two sets of cavities 15. A tension spring 17 is fixedly connected between the cavity 15 and the clamping rod 16. A support block 18 is fixedly connected to the top of the connecting block 11. A placement cavity 19 is provided inside the support block 18. A pushing rod 20 is slidably connected inside the placement cavity 19. A support spring 21 is fixedly connected between the pushing rod 20 and the placement cavity 19.

[0024] When the clamping block 12 needs to be replaced, pull the push rod 20 upward, so that the push rod 20 drives the support spring 21 to retract, and the locking rods 16 that are attached to both sides of the push rod 20 separate from the push rod 20. Under the reset action of the tension spring 17, the locking rods 16 can be reset, so that the two sets of locking rods 16 separate from the locking block 14 respectively, thereby facilitating the quick separation of the clamping block 12 and the connecting block 11.

[0025] When the replacement clamping block 12 needs to be installed, pull the push rod 20 upward to slide the locking block 14 at the clamping block 12 into the locking groove 13. Then loosen the push rod 20, and the push rod 20 will be reset under the action of the support spring 21, so that the push rod 20 moves downward. When the two sides of the bottom of the push rod 20 contact each set of locking rods 16, each set of locking rods 16 is subjected to the pushing force and can slide into the locking block 14, thereby facilitating the quick installation of the clamping block 12.

[0026] Working principle: When the rotating head of the detector needs to be clamped, the electric push rod 3 is activated, and its output end pushes the mounting block 8 upward. Through the transmission of the connecting rod 9, the two sets of sliders 6 move towards the center along the slide groove 5, driving the connecting plate 10 and the clamping block 12 to move towards the center at the same time, thus achieving a tight clamping of the rotating head. When the rotating head does not need to be clamped, the electric push rod 3 is activated again, and its output end drives the mounting block 8 downward. The two sets of sliders 6 move towards both sides of the fixed block 4 along the slide groove 5, driving the connecting plate 10 and the clamping block 12 to move towards both sides at the same time. The rotating head loses the tight clamping force. When the clamping block 12 needs to be replaced, the push rod 20 is pulled upward, the support spring 21 retracts, and the clamping rod 16 separates from the push rod 20. Under the reset action of the tension spring 17, the clamping rod 16 resets and separates from the clamping block 14, facilitating the quick separation of the clamping block 12 from the connecting block 11. When installing the replaced clamping block 12, first pull the pushing rod 20 upward to slide the clamping block 14 into the slot 13, then release the pushing rod 20. Under the action of the support spring 21, the pushing rod 20 resets and moves downward, pushing the clamping rod 16 to slide into the clamping block 14, thus achieving quick installation of the clamping block 12.
