DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] See also Figure 1-Figure 6The 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, two guide rods 2 are horizontally installed on the upper end of the main body bracket 1, and two guide rail slides 3 are provided. The two guide rail slides 3 are respectively slidably installed on the left and right sides of the upper ends of the two guide rods 2, and 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 and provided with adjusting screws 62, and the lower ends of the outer parts of the multiple adjusting screws 62 are longitudinally sleeved with springs 63, and two probe limit blocks 73 are provided. The two probe limit blocks 73 are respectively horizontally fixed at the lower ends of the multiple adjusting screws 62, and the upper ends of the two probe limit blocks 73 are respectively against the multiple springs 63, and the probe fixing grooves 71 are opened in the two probe limit blocks 73, and the rear ends of the two probe fixing grooves 71 are fixed with fixed blocks 72, and the front ends of the two probe limit blocks 73 are threadedly inserted with probe clamping fasteners 7, and the two probe fixing The probe body 9 is longitudinally installed in the groove 71, and extension plates 81 are horizontally fixed on the left and right sides of the rear end of the main bracket 1 respectively. Bending cylinders 82 are symmetrically installed on the upper ends of the two extension plates 81, and rubber pistons 83 are plugged in the two bending cylinders 82. Piston pull rods 84 are installed on 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 two extension cylinders 86. Bellows expansion tubes 88 are sealed in the two extension cylinders 86, and sealed connecting tubes 89 are longitudinally installed on the lower ends of the two bellows expansion tubes 88. Limiting rings 810 are horizontally fixed on the outside of the two sealing connecting tubes 89. Small suction cups 811 are installed on 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 it is very difficult for the original device to meet the scanning accuracy requirements by purely manual serial scanning, and the risk of missed detection of defects is high due to human factors, and the efficiency is low.

[0017] As the first embodiment of the present invention: the left and right sides of the lower end of the main support 1 are fixed with magnetic sheets 8 by epoxy resin glue, and the added magnetic sheets 8 can be used to adsorb the device to the metal detection surface and keep it stable. The upper ends of multiple adjustment screws 62 are screwed with butterfly bolts 61, and the multiple butterfly bolts 61 are respectively against the upper ends of the two fixed guide blocks 6. The added multiple butterfly bolts 61 are rotated outside the multiple adjustment screws 62 to adjust the positions of the multiple adjustment screws 62 at the two fixed guide blocks 6, thereby changing the heights of the two probe limit blocks 73 and the two probe bodies 9.

[0018] The rear ends of the two probe bodies 9 are respectively abutted against the two fixed abutments 72, and the front ends of the two probe bodies 9 are respectively abutted against the two probe clamping fasteners 7. By adding two probe bodies 9 with the rear ends abutted against the two fixed abutments 72, and the front ends of the two probe bodies 9 are respectively abutted against the two probe clamping fasteners 7, the two probe bodies 9 can be limited in the longitudinal direction.

[0019] 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 rails 3. The outer surface of the added synchronous belt 4 is engraved with millimeter scales, which is convenient for inspectors to know the distance between the two guide rails 3 based on it.

[0020] The upper ends of the two bending cylinders 82 are both penetrated by limiting bolts 85 through the thread principle, and the threaded ends of the two limiting bolts 85 are respectively tightly abutted against the upper ends of the two piston pull rods 84. By adding two limiting bolts 85 with threaded ends respectively abutting against the upper ends of the two piston pull rods 84, the two rubber pistons 83 can be prevented from moving by themselves in the two bending cylinders 82 due to negative pressure.

[0021] 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).

[0022] As a second embodiment of the present invention: 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 and move backwards through the thread principle until the rear ends of the two probe bodies 9 are respectively against the two fixed abutting blocks 72, and the front ends of the two probe bodies 9 are respectively tightly abutted against the two probe clamping fasteners 7. The multiple springs 63 provided make the two probe limit blocks 73 have a certain elasticity to the bottom, so that the probe body 9 forms a good coupling with the contact surface during detection. The two guide rail slides 3 are then moved toward each other, so that the two probe bodies 9 can be moved toward each other until the two probe bodies 9 are moved to the minimum position required for the weld serial scanning. The device is perpendicular to the weld, and the center positions of the incident points of the two probe bodies 9 are aligned with the fixed reference line for the weld serial scanning to be detected. The device is adsorbed on the metal detection surface by the magnetic sheet 8 to keep it stable. Then, with reference 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. Fast and accurate ultrasonic serial scanning can be achieved by moving the two probe bodies away from and close to each other.

[0023] As a third embodiment of the present invention: when the device is placed on a metal detection surface, the two magnetic sheets 8 adsorb the device to the metal detection surface, and the two return springs 87 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), and 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, and when the two piston rods 84 are facing 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, to ensure 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 is also ensured. After completion, tighten the two limit bolts 85 again so that the threaded ends of the two limit bolts 85 are tightly pressed 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 the negative pressure.
