Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment accessories, and particularly relates to a three-dimensional mobile ultrasonic probe detection fixture. Background Art

[0002] As a standard accessory of the probe, the probe detection fixture mainly plays the role of providing pressure and fixing for the probe and the encoder. However, most of the commonly used probe detection fixtures at present are structures fixedly installed on an external platform and cannot move flexibly according to needs. When detecting workpieces with different thicknesses and different diameters, it is necessary to automatically and effectively collect data for the workpieces to be detected. Considering the detection range of the workpieces to be detected according to the thickness and diameter of the workpieces to be detected, it is necessary to move the probe detection fixture carrying the probe within a certain range.

[0003] For the probe detection fixture currently fixed to the external platform through a truss, when the thickness of the sample to be detected is different, or the diameter of the sample is different, because its fixed position does not meet the requirements and it is inconvenient to adjust the distance between the probe and the workpiece to be detected, therefore, without moving the position of the workpiece to be detected, it is impossible to automatically and effectively collect information using the same probe detection fixture.

[0004] Moreover, the probe detection fixture fixed at a fixed position on the external platform is not convenient to disassemble. Even if it can be disassembled, because the structure of the detection fixture cannot be changed, therefore, it cannot provide good protection for the cleanliness of the probe clamped by the detection fixture and the integrity of the probe detection fixture itself.

[0005] Therefore, it is very necessary to design a three-dimensional mobile ultrasonic probe detection fixture that is convenient for storage. Summary of the Utility Model

[0053] An external three-dimensional moving probe detection fixture provided by the present utility model is convenient for storing and protecting the probe from being damaged. The installation part is conveniently and stably connected to the external platform, and the structure itself can freely adjust the height. The detection part realizes three-dimensional movement in the X, Y, and Z directions. For workpieces to be detected with different thicknesses and different diameters, it can be flexibly moved to a suitable position to automatically and effectively collect information.

[0054] When the detection fixture needs to be used:

[0055] Unfasten the lock hook 24, manually turn the hole plate 12 upward to the horizontal plane, and rotate the second fastener 4 to fix the hole plate at both ends on the first side of the hole plate 12 to prevent the hole plate from reversing downward.

[0056] Press the buttons 22 on the start-stop switches 15 on both groups of sliding grooves simultaneously. The buttons 22 drive the connecting shaft 154 to move downward, and the connecting shaft 154 drives the latch 151 to move backward. After the two groups of racks 14 are unlocked, they move downward synchronously in the sliding grooves 13. When the orifice plate 12 descends to an appropriate height, release the two buttons 22 simultaneously. The return spring 153 pushes the latch 151 to reset, and the first end of the latch 151 snaps into the card slot 141 between the teeth of the rack 14, fixing the height of the orifice plate 12.

[0057] Open the third fastener 21 and flip the outer rod 17 of the telescopic rod so that it is perpendicular to the bottom surface of the orifice plate 12.

Tighten the first fastener 20 to lock the inner rod and the outer rod. Fix the outer rod to the external platform through bolts.

[0058] Pull out the pin connecting the connecting baffle 18 and the orifice plate 12, and turn the baffle 18 downward to be perpendicular to the ground, in a state where it does not block the threaded hole.

[0059] Take out the detection component, place the first sliding rod 31 parallel to the external platform, align the probe fixing assembly 1 with the component to be detected on the external platform, and fix the bottom of the first sliding rod 31 to the threaded hole on the orifice plate 12 through bolts at an appropriate position.

[0060] According to the different thicknesses and diameters of the components to be detected, move the corresponding sliding rods to keep the probe fixing assembly 1 always in contact with the component to be detected. Rotate the locking knob 34 to fix the probe fixing assembly and the corresponding sliding rod for effective information collection.

[0061] After the detection is completed, remove the detection component from the orifice plate 12 and place it in the box body 11. Then remove the outer rod 17 of the telescopic rod from the external platform, contract it to the bottom surface of the orifice plate and lock it. Flip the baffle upward and fix it with a pin. Rotate the second fastener 4 so that it no longer restricts the orifice plate. At this time, the orifice plate flips downward and locks with the box body 11.
