DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figures 1-6 The present invention provides a technical solution: a manual ultrasonic serial scanning synchronization device, comprising a main body bracket 1, a guide rail slide 3 and a probe limit block 73. The upper end of the main body bracket 1 is horizontally mounted with two guide rods 2, and the guide rail slide 3 is provided with two. The two guide rail slides 3 are slidably mounted on the left and right sides of the upper ends of the two guide rods 2. The front ends of the two guide rail slides 3 are fixed with fixed guide blocks 6. The front and rear sides of the upper ends of the two fixed guide blocks 6 are penetrated by adjusting screws 62. The lower ends of the outer ends of the multiple adjusting screws 62 are longitudinally sleeved with springs 63. There are two probe limit blocks 73. The two probe limit blocks 73 are respectively fixed horizontally at the lower ends of the multiple adjusting screws 62. The upper ends of the two probe limit blocks 73 are respectively against the multiple springs 63. The probe body 9 is longitudinally installed in the fixed groove 71, and extension plates 81 are horizontally fixed on the left and right sides of the rear end of the main bracket 1. The upper ends of the two extension plates 81 are symmetrically installed with bending cylinders 82, and rubber pistons 83 are plugged in the two bending cylinders 82. Piston pull rods 84 are installed at the opposite inner ends of the two rubber pistons 83. The lower ends of the two bending cylinders 82 pass through the two extension plates 81 and are sealed with the two extension cylinders 86. Bellows telescopic tubes 88 are sealed in the two extension cylinders 86, and sealed connecting tubes 89 are longitudinally installed at the lower ends of the two bellows telescopic tubes 88. Limiting rings 810 are horizontally fixed on the outside of the two sealing connecting tubes 89. Small suction cups 811 are installed at the lower ends of the two sealing connecting tubes 89, and reset springs 87 are longitudinally installed on the upper ends of the two limiting rings 810. This design solves the problem that the original device uses purely manual serial scanning to meet the scanning accuracy requirements, the risk of missed detection of defects is high due to human factors, and the efficiency is low.

[0025] As a first embodiment of the present invention, magnetic sheets 8 are fixed to the left and right sides of the lower end of the main frame 1 using epoxy resin glue. The added magnetic sheets 8 can securely attach the device to the metal detection surface. The upper ends of multiple adjustment screws 62 are screwed with butterfly bolts 61, which respectively abut the upper ends of the two fixed guide blocks 6. By rotating the added butterfly bolts 61 outside the multiple adjustment screws 62, the position of the multiple adjustment screws 62 at the two fixed guide blocks 6 can be adjusted, thereby changing the height of the two probe limit blocks 73 and the two probe bodies 9.

[0026] The rear ends of the two probe bodies 9 are respectively against the two fixed blocks 72, and the front ends of the two probe bodies 9 are respectively against the two probe clamping fasteners 7. By adding two probe bodies 9 with the rear ends respectively against the two fixed blocks 72 and the front ends respectively against the two probe clamping fasteners 7, the two probe bodies 9 can be limited in the longitudinal direction.

[0027] Synchronous gears 5 are installed on the left and right sides of the upper end of the main bracket 1, and a synchronous belt 4 is installed between the two synchronous gears 5. The added synchronous belt 4 slides through the two guide rail slides 3. The outer surface of the added synchronous belt 4 is engraved with millimeter scales, which makes it convenient for inspectors to know the distance between the two guide rail slides 3 based on it.

[0028] The upper ends of the two bending cylinders 82 are each penetrated by a limiting bolt 85 through the threaded principle, and the threaded ends of the two limiting bolts 85 are respectively tightly pressed against the upper ends of the two piston pull rods 84. By adding two limiting bolts 85 with threaded ends respectively pressing against the upper ends of the two piston pull rods 84, the two rubber pistons 83 can be prevented from moving on their own in the two bending cylinders 82 due to negative pressure.

[0029] The upper ends of the two return springs 87 are respectively against the two extension plates 81. By adding the upper ends of the two return springs 87 and respectively against the two extension plates 81, the two limit rings 810 can be pushed down by the spring thrust, so that the two limit rings 810 drive the two sealing connecting tubes 89 and the two small suction cups 811 to move downward, so that the two small suction cups 811 can cooperate with the magnetic sheet 8 to be tightly adsorbed on the metal detection surface (in this process, the two corrugated telescopic tubes 88 can also be pulled downward to extend slightly).

[0030] As a second embodiment of the present utility model: in actual use, the two probe bodies 9 are longitudinally arranged in the two probe fixing grooves 71, and the two probe bodies 9 are placed on the same horizontal line, and then the two probe clamping fasteners 7 are screwed to rotate the probe clamping fasteners 7 backward through the thread principle until the rear ends of the two probe bodies 9 are respectively against the two fixed blocks 72, and the front ends of the two probe bodies 9 are respectively tightly against the two probe clamping fasteners 7. The multiple springs 63 provided make the two probe limit blocks 73 have a certain elasticity towards the bottom, so that the probe body 9 forms a good contact with the contact surface during detection. Coupling, and then by moving the two guide rail slides 3 toward each other, the two probe bodies 9 can be moved toward each other until the two probe bodies 9 move to the minimum position required for the weld serial scanning, the device is perpendicular to the weld, the center position of the incident point of the two probe bodies 9 is aligned with the fixed reference line for the weld serial scanning to be detected, and the device is adsorbed on the metal detection surface by the magnetic sheet 8 to keep it stable, and then referring to the millimeter scale, the two guide rail slides 3 are moved to drive the two probe bodies 9 to move to the maximum position required for the weld serial scanning, and fast and accurate ultrasonic serial scanning can be achieved by moving the two probe bodies away from and close to each other.

[0031] As a third embodiment of the present invention: when the device is placed on a metal detection surface and the two magnetic sheets 8 adsorb the device to the metal detection surface, the two return springs 87 will also press down the two limit rings 810, so that the two limit rings 810 drive the two sealing connecting tubes 89 and the two small suction cups 811 to move downward until the two small suction cups 811 are attracted to the metal detection surface (in this process, the two corrugated telescopic tubes 88 extend slightly downward), then loosen the two limit bolts 85 so that the threaded ends of the two limit bolts 85 are no longer in contact with the two piston rods 84, and then pull the two piston rods 84 toward each other, and at the same time let another staff member continue to press down the two small suction cups 811, until the two piston rods 84 move toward each other. When moving, the two rubber pistons 83 can suck the air in the two small suction cups 811 through the two bent cylinders 82, the two extension cylinders 86, the two corrugated telescopic tubes 88 and the two sealed connecting tubes 89, ensuring that the negative pressure in the two small suction cups 811 is less than that in the outside. By reducing the amount of air in the two small suction cups 811, the adsorption force of the two small suction cups 811 on the metal detection surface can be effectively improved, and the stable effect of the device adsorbed on the metal detection surface can be ensured. After completion, tighten the two limit bolts 85 again so that the threaded ends of the two limit bolts 85 are tightly against the upper ends of the two piston pull rods 84 again, which can prevent the two rubber pistons 83 from moving by themselves in the two bent cylinders 82 due to negative pressure.
