Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection equipment, and more specifically to a flaw detection equipment for detecting metal parts of a workbench. Background Art

[0002] The flaw detection equipment used for metal parts inspection mainly refers to various instruments used to inspect the internal and / or surface defects of metal parts in industrial non-destructive testing technology. It is mainly used to check whether there are cracks, inclusions, pores and other defects inside or on the surface of the metal parts of the workbench. It is widely used in the flaw detection of various metal materials.

[0003] China Patent Authorization Announcement No.: CN 217605694 U provides a fluorescent flaw detection device for metal parts inspection. The utility model has baffles installed at both ends of the workbench at the spraying position of the spray pipe through hinges, and a bending layer is installed on the inner side of the baffle, and cut-off plates are installed at both ends of the bending layer. When the flaw detection agent is sprayed on the metal parts, the baffle is pulled up and adsorbed on the metal shells of the control system and the flaw detection agent circulation system respectively by means of the magnets on the inner wall, and the splashing flaw detection agent is blocked by the baffle.

[0004] In actual use of the prior art, the flaw detection agent needs to be sprayed from top to bottom on the outer surface of the metal part through a spray pipe. Since the flaw detection agent is prone to uneven spraying due to changes in the spray force and flow rate during the falling process, which affects the flaw detection effect, a flaw detection device for workbench metal part inspection is proposed.

Then the valve on the input pipe is opened to pump the flaw detection agent in the storage box into the penetration box through the pump to submerge the lower part of the metal part. At this time, the rotating metal part will be evenly in full contact with the flaw detection agent inside the penetration box to ensure that the outer surface of the metal part can be evenly contacted with the flaw detection agent. Compared with the existing method of spraying through a spray pipe, the flaw detection equipment has better effect and can avoid uneven spraying on the surface of the metal part due to changes in the spraying intensity and flow rate.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) This solution starts the motor and drives the two rotating rollers to rotate simultaneously through the cooperation of the pulley and the belt, driving the metal part to rotate. Then, the valve on the input pipe is opened to pump the flaw detection agent in the storage box into the penetration box through the pump to submerge the lower part of the metal part.

Then, the motor 202 is started to drive the two rotating rollers 203 to rotate simultaneously through the cooperation of the pulley 204 and the belt 205, thereby driving the metal part 206 to rotate.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The inner cavity of the cabinet 101 is provided with a flaw detection agent conveying mechanism 3, including a storage box 301 fixedly connected to the inner cavity of the cabinet 101, an input pipe 302 is fixedly connected to the inner cavity of the storage box 301, a pump 304 is provided at the lower end of the input pipe 302, a discharge pipe 303 is connected to the upper surface of the storage box 301, and a filter cartridge 307 is movably connected to the top of the inner cavity of the storage box 301;
