Description
Technical Field
[0001] The utility model relates to the technical field of parts flaw detection, in particular to a fluorescent penetrant delivery device. Background Art
[0002] Fluorescent penetrant is a chemical widely used in surface inspection of various metal, non-metal, ceramic and other material workpieces, and can efficiently detect various opening defects. The penetrant placement method in the existing fluorescent penetrant inspection line is the immersion method, where the entire part is immersed in a stainless steel penetration tank filled with penetrant. For parts with inner cavities, the penetrant covers the surface and interior of the part. However, if only the surface of the part needs to be inspected, a certain amount of penetrant still needs to be consumed inside the part. In addition, the penetration method requires a large amount of penetrant. Currently, most of the penetration methods on the market use the spray method for penetration.
[0003] Publication number "CN215115956U" provides a fluorescent penetrant delivery device, which places the parts to be sprayed on a workbench, stores the fluorescent penetrant in the carrying airbag, and uses a sensor to measure the size of the parts. The movement of the driving component is controlled according to the size of the parts. The driving component squeezes the pushing airbag, and the pushing airbag squeezes the carrying airbag. A certain amount of fluorescent penetrant is transported to the water pipe through a transport pipe and sprayed on the parts through a spray head.
[0004] However, the above technical solutions and the prior art have the following defects:
[0005] Although the fluorescent penetrant delivery device can spray a certain amount of fluorescent penetrant on parts according to the size of the parts, the error of the drive component and the sensor is relatively large during actual use, and the parts cannot be sprayed quantitatively accurately. In addition, the spray head in the delivery device can only spray the upper end surface of the part, and cannot spray the side of the part at the same time. The spray range is limited, and its practicality needs to be improved. Utility Model Content

[0026] Embodiment 1:

The protective door 3 is an openable and closable structure. The openable and closable protective door 3 is convenient for staff to take and place the workpiece 5 to be sprayed inside the delivery box 1.

The workpiece 5 to be sprayed is placed inside the delivery box 1. A quantitative spraying component 2 for spraying fluorescent penetrant on the surface of the workpiece 5 to be sprayed is provided on the upper side of the delivery box 1. A supporting component 4 for supporting the workpiece 5 to be sprayed is provided inside the delivery box 1.
[0028] The quantitative spray assembly 2 includes a storage chamber 24, a self-priming pump 25, a liquid outlet pipe 26, an intelligent flow meter 27, a connecting pipe 28, a guide shell 29 and a spray head 211. A storage chamber 24 is opened on the lower side of the delivery box 1. The storage chamber 24 is convenient for the delivery box 1 to store the fluorescent penetrant. A self-priming pump 25 is installed on the lower side of the right end surface of the delivery box 1. When working, the self-priming pump 25 will transport the fluorescent penetrant in the storage chamber 24 to the liquid outlet pipe 26. The outlet of the self-priming pump 25 is connected to the liquid outlet pipe 26, which is connected to the intelligent flow meter 27. The liquid outlet pipe 26 will guide the fluorescent penetrant to the intelligent flow meter 27.
[0029] The outlet of the liquid outlet pipe 26 is connected to an intelligent flow meter 27. When working, the intelligent flow meter 27 can measure the flow rate of the fluorescent penetrant in real time and transmit the measured flow value to the programmable logic controller 21 in real time. Since the internal detailed structure and working principle of the intelligent flow meter 27 are relatively mature technologies in the prior art, they will not be described in detail here. The lower end of the intelligent flow meter 27 is connected to a connecting pipe 28, which is connected to the intelligent flow meter 27 and the guide shell 29. The connecting pipe 28 will guide the fluorescent penetrant into the guide shell 29. The lower end of the connecting tube 28 is fixedly connected to a guide shell 29. The internal space of the guide shell 29 is larger than the volume of the workpiece 5 to be sprayed. The guide shell 29 will divert the fluorescent penetrant to multiple spray heads 211.

There are multiple spray heads 211, and the specifications of the multiple spray heads 211 are the same. The multiple spray heads 211 will spray the fluorescent penetrant outward so that the sprayed fluorescent penetrant adheres and penetrates into the upper end face, left and right end faces, and front and rear end faces of the workpiece 5 to be sprayed.
[0030] A support plate 22 is fixedly connected to the upper side of the left end surface of the delivery box 1, and the support plate 22 supports the programmable logic controller 21 and the relay 23. The programmable logic controller 21 is installed on the upper end surface of the support plate 22, and the programmable logic controller 21 is respectively connected to the intelligent flow meter 27 and the relay 23 through signal lines. The programmable logic controller 21 can internally store instructions for performing operations such as logical operations, sequential control, timing, counting and arithmetic operations, so as to automatically control the switch of the self-priming pump 25 through the relay 23. The relay 23 is installed on the lower end surface of the support plate 22, and the relay 23 is connected to the intelligent flow meter 27 and the relay 23 through the signal line. It is connected to the self-priming pump 25, and the relay 23 facilitates the programmable logic controller 21 to control the operation of the self-priming pump 25.

A discharge valve 12 is installed below the replenishing valve 11, and the materials of the discharge valve 12 and the replenishing valve 11 are both stop valves. The outlet of the discharge valve 12 is connected with the inlet of the external waste liquid treatment tank through a pipeline. The discharge valve 12 facilitates the staff to discharge and replace the fluorescent penetrant inside the storage chamber 24.
[0031] Embodiment 2:
[0032] On the basis of Example 1, in this embodiment, by controlling the electric push rod 44 to perform a contraction action, the electric push rod 44 can drive the supporting mesh plate 41 to move upward through the connecting block 42, so that the supporting mesh plate 41 can drive the workpiece 5 to be sprayed to move up to the inside of the guide shell 29. When the electric push rod 44 is controlled to perform an extension action, the supporting mesh plate 41 can drive the workpiece 5 to be sprayed after spraying to move downward to the initial position, so that the staff can take away the workpiece 5 to be sprayed after spraying for inspection.
[0033] The supporting assembly 4 includes a supporting mesh plate 41, a connecting block 42 and an electric push rod 44. The electric push rods 44 are symmetrically installed on the left and right sides of the delivery box 1. Two groups of electric push rods 44 are installed, and the two groups of electric push rods 44 have the same specifications. The two groups of electric push rods 44 will drive the supporting mesh plate 41 to move up and down when working. A connecting block 42 is provided at the lower end of the electric push rod 44. The connecting block 42 is connected to the supporting mesh plate 41 by welding. The connecting block 42 facilitates the electric push rod 44 to drive the supporting mesh plate 41 to move up and down.
[0034] A supporting mesh plate 41 is provided at the lower end of the connecting block 42, which not only supports the workpiece 5 to be sprayed, but also blocks large-grained insoluble impurities in the fluorescent penetrant flowing through. Limiting bars 43 are symmetrically fixedly connected to the left and right sides of the inner wall of the delivery box 1, and the limiting bars 43 are connected to the delivery box 1 by welding. The limiting bars 43 will block and limit the downward moving supporting mesh plate 41 to prevent the supporting mesh plate 41 from moving downward too much. A control panel is installed on the left side of the front end face of the delivery box 1, and the control panel is connected to two groups of electric push rods 44 through wires. The control panel facilitates the staff to control the extension and retraction of the two groups of electric push rods 44.
[0035] Working principle: The staff first opens the replenishing valve 11 to replenish an appropriate amount of fluorescent penetrant into the storage chamber 24. During this process, the liquid level of the fluorescent penetrant in the storage chamber 24 cannot be higher than the height of the replenishing valve 11. Then, the protective door 3 is opened and the workpiece 5 to be sprayed is placed in the middle position of the upper end surface of the supporting mesh plate 41 (refer to Figure 2 ), at this time, the control panel controls the two sets of electric push rods 44 to retract, so that the two sets of electric push rods 44 drive the supporting mesh plate 41 to move upward through the connecting block 42, and the supporting mesh plate 41 drives the workpiece 5 to be sprayed to move upward together, and moves upward until the supporting mesh plate 41 contacts the bottom of the guide shell 29 (reference Figure 4 ); then close the protective door 3 and start the programmable logic controller 21, so that the programmable logic controller 21 controls the self-priming pump 25 to work through the relay 23. At this time, the working self-priming pump 25 will pump the fluorescent penetrant in the storage chamber 24 to the intelligent flow meter 27 through the liquid outlet pipe 26, and then the fluorescent penetrant will pass through the intelligent flow meter 27 and the connecting pipe 28 in turn into the guide shell 29, and the guide shell 29 will divert the entering fluorescent penetrant to multiple spray heads 211, and finally the multiple spray heads 211 will spray the fluorescent penetrant outward on the upper end face, left and right end faces and front and rear end faces of the workpiece 5 to be sprayed for penetration, and the excess fluorescent penetrant on the surface of the workpiece 5 to be sprayed will pass through the supporting mesh plate 41 and drip again It falls into the storage chamber 24 for recycling; in this process, the intelligent flow meter 27 will measure the flow rate of the fluorescent penetrant flowing through it in real time and transmit it to the programmable logic controller 21. When the programmable logic controller 21 detects through the intelligent flow meter 27 that the flow rate has reached the required value, it will shut down the self-priming pump 25 through the relay 23, so as to carry out quantitative spraying on the workpiece 5 to be sprayed, so as to avoid too much or too little spraying of the fluorescent penetrant; at this time, the staff will control the two groups of electric push rods 44 to extend, so that the electric push rods 44 drive the supporting mesh plate 41 to move down to the initial position through the connecting block 42, and then open the protective door 3 to take the workpiece 5 to be sprayed after the spray penetration out of the delivery box 1 for inspection.
