Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical spark detection, and in particular to an electrical spark detection device for metal surface inspection. Background Technology
[0002] The working principle of the electric spark detector is based on the principle of high voltage breakdown. When the high voltage probe of the instrument emits DC or pulsed high voltage, if there are defects in the anti-corrosion layer on the metal surface, the high voltage will form an air gap breakdown at these defects, generating a spark discharge. At the same time, a pulse signal will be sent to the alarm circuit during this process, triggering an audible and visual alarm, thereby indicating the location of the defect.
[0003] When using an EDM (Electrical Discharge Machining) device for non-destructive testing, the probe is connected to the main unit via a cable. One end of the grounding wire is connected to the main unit, and the other end is connected to the object being tested. A probe brush is then connected to one side of the probe. The main unit is then turned on using a button, and the voltage is adjusted using a knob. The probe brush is then brought into contact with the object being tested to inspect the metal surface. However, the cable is often quite long, and when the probe moves, the unused portion of the cable can become tangled. This can affect the subsequent storage and use of the cable, thus impacting the use of the EDM device. Utility Model Content
[0004] The technical problem this invention aims to solve is that when using cables, if the cable length is long, the unused portion of the cable may become entangled during probe movement, affecting subsequent cable storage and use, and consequently impacting the use of the electric spark detector.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an electric spark detection device for metal surface inspection, including a main unit and an installation assembly. A button is provided on one side of the main unit, a knob is provided on one side of the main unit, a cable is provided on one side of the main unit, a probe is provided on one side of the cable, a probe brush is provided on one side of the probe, a grounding wire is provided on one side of the main unit, and an anti-winding device is provided on one side of the main unit by means of the installation assembly. The anti-winding device limits the winding of the unused part of the cable.
[0006] The effect achieved by the above components is as follows: When using the electric spark testing device for non-destructive testing, the probe is connected to the main unit via a cable. At this time, an anti-winding device is used to wind up and limit the unused part of the cable. One end of the grounding wire is connected to the main unit, and the other end is connected to the object being tested. Then, a probe brush is connected to one side of the probe. Next, the main unit is turned on by pressing a button, and the voltage is adjusted by turning a knob. Then, the probe brush is brought into contact with the object being tested to perform metal surface testing.
[0007] Preferably, the anti-winding device includes a placement plate, a fixing plate is fixedly connected to one side of the placement plate, a spring is fixedly connected to one side of the fixing plate, a limiting plate is fixedly connected to one side of the spring, a take-up column is fixedly connected to one side of the placement plate, and the side of the limiting plate near the take-up column is U-shaped.
[0008] The aforementioned components achieve the following effects: When using the cable, the limiting plate can be moved away from the take-up column. At this time, the spring on one side of the fixed plate deforms, and the unused portion of the cable is then wound onto the take-up column on the side of the placement plate. The limiting plate is then released, and the spring returns to its original position, causing the limiting plate to contact the take-up column. The limiting plate then limits the upper end of the take-up column, preventing the cable wound on the take-up column from detaching. By using the anti-tangling device, the unused portion of the cable can be wound and limited, preventing it from moving and tangling when the probe moves, thus avoiding any impact on the subsequent storage and use of the cable. This facilitates the subsequent storage and use of the EDM detector, thereby improving the effectiveness of the EDM detector.
[0009] Preferably, a telescopic rod is fitted inside the spring, and the two ends of the telescopic rod are fixedly connected to the fixing plate and the limiting plate, respectively.
[0010] The effect achieved by the above components is to restrict the shape of the spring by using a telescopic rod, thereby preventing the spring from bending and affecting its use.
[0011] Preferably, a plurality of anti-slip blocks are fixedly connected to one side of the limiting plate, and the plurality of anti-slip blocks are arranged at equal intervals on one side of the limiting plate.
[0012] The effect achieved by the above components is to increase the friction between the operator and the limit plate by using anti-slip blocks, making it easier for the limit rod to be moved.
[0013] Preferably, a sponge pad is fixedly connected to the side of the limiting plate near the winding column, and the size of the sponge pad is adapted to the size of the limiting plate.
[0014] The effect achieved by the above components is to improve the contact sealing between the limiting plate and the winding column by using a sponge pad, so that the limiting plate can make closer contact with the winding column, thereby improving the performance of the limiting plate.
[0015] Preferably, the mounting assembly includes a square tube, one side of which is fixedly connected to the main unit, a bolt is threaded into one side of the square tube, a mounting plate is threaded to one side of the bolt, and one side of the mounting plate is fixedly connected to the placement plate.
[0016] The effect achieved by the above components is as follows: when using the anti-entanglement device, the placement plate can be moved so that the mounting plate on one side of the placement plate is inserted into the square tube. Then, the bolt is rotated so that the bolt passes through the square tube and is fixed to the mounting plate, thus completing the fixation of the placement plate position. By using the mounting components, the anti-entanglement device can be quickly fixed, making it convenient for operators to use the anti-entanglement device in the future.
[0017] Preferably, an operating block is fixedly connected to one side of the bolt, and the size of the operating block is adapted to the size of the bolt.
[0018] The effect achieved by the above-mentioned components is to increase the contact area between the bolt and the operator by using the operating block, thereby making the bolt easier to rotate.
[0019] Preferably, an auxiliary block is fixedly connected to one side of the mounting plate, and the dimension of the auxiliary block on the side away from the mounting plate is smaller than the dimension on the other side.
[0020] The effect achieved by the above components is to reduce the size of one side of the mounting plate by using the auxiliary block, making it easier to insert the mounting plate into the square tube.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using an anti-tangling device, the unused portion of the cable can be wound up and limited, preventing it from moving and getting tangled when the probe moves. This would not affect the subsequent storage and use of the cable, thus facilitating the storage and use of the electric spark detector and improving its performance. Attached Figure Description

[0031] Figures 1 to 4 The illustrated spark testing device for metal surface inspection includes a main unit 1 and a mounting assembly 3. A button 4 and a knob 5 are located on one side of the main unit 1. A cable 6 is also located on one side of the main unit 1, with a probe 7 and a probe brush 8 on one side of the cable 6. A grounding wire 9 is located on one side of the main unit 1. An anti-winding device 2 is provided on one side of the main unit 1 via the mounting assembly 3, which winds up and limits the unused portion of the cable 6. When performing non-destructive testing using the spark testing device, the probe 7 is connected to the main unit 1 via the cable 6. The anti-winding device 2 winds up and limits the unused portion of the cable 6. One end of the grounding wire 9 is connected to the main unit 1, and the other end is connected to the object being tested. The probe brush 8 is then connected to one side of the probe. The main unit 1 is then turned on via the button 4, and the voltage is adjusted via the knob 5. The probe brush 8 then contacts the object being tested to perform metal surface inspection.
[0032] Figures 1 to 4The anti-winding device 2 shown includes a placement plate 21, a fixing plate 22 fixedly connected to one side of the placement plate 21, a spring 23 fixedly connected to one side of the fixing plate 22, a limiting plate 24 fixedly connected to one side of the spring 23, a take-up column 25 fixedly connected to one side of the placement plate 21, and the limiting plate 24 is U-shaped on the side near the take-up column 25. When using cable 6, the limiting plate 24 can be moved away from the take-up column 25. At this time, the spring 23 on one side of the fixing plate 22 deforms, and the unused part of cable 6 is then wound onto the take-up column 25 on the side of the placement plate 21. Then the limiting plate 24 is released, and the spring 23 returns to its original position, causing the limiting plate 24 to contact the take-up column 25. The limiting plate 24 then limits the upper end of the take-up column 25, preventing the cable 6 wound on the take-up column 25 from detaching. By using the anti-tangling device 2, the unused part of cable 6 can be wound and limited, preventing the unused part of cable 6 from moving and tangling when the probe 7 moves, which would affect the subsequent storage and use of cable 6. This facilitates the subsequent storage and use of the electric spark detector, thereby improving the performance of the electric spark detector.
[0033] Figures 1 to 4 The spring 23 shown has a telescopic rod 26 inside, with its two ends fixedly connected to the fixed plate 22 and the limiting plate 24, respectively. The telescopic rod 26 restricts the shape of the spring 23, preventing it from bending and affecting its use. Several anti-slip blocks 27 are fixedly connected to one side of the limiting plate 24, arranged equidistantly. The anti-slip blocks 27 increase the friction between the operator and the limiting plate 24, making the limiting rod easier to move. A sponge pad 28 is fixedly connected to the side of the limiting plate 24 near the take-up column 25, and the size of the sponge pad 28 is adapted to the size of the limiting plate 24. The sponge pad 28 improves the contact sealing between the limiting plate 24 and the take-up column 25, allowing for tighter contact and improving the performance of the limiting plate 24.
[0034] Figures 1 to 4 The mounting assembly 3 shown includes a square tube 31, one side of which is fixedly connected to the main unit 1. A bolt 32 is threaded into one side of the square tube 31, and a mounting plate 33 is threaded onto one side of the bolt 32.

When using the anti-entanglement device 2, the placement plate 21 can be moved so that the mounting plate 33 on one side of the placement plate 21 is inserted into the square tube 31. Then, the bolt 32 is rotated so that it passes through the square tube 31 and is fixed to the mounting plate 33, thus completing the fixation of the placement plate 21. By using the mounting assembly 3, the anti-entanglement device can be quickly fixed, making it convenient for operators to use the anti-entanglement device subsequently.
[0035] Figures 1 to 4 An operating block 34 is fixedly connected to one side of the bolt 32, and the size of the operating block 34 is adapted to the size of the bolt 32. By using the operating block 34, the contact area between the bolt 32 and the operator is increased, making it easier to rotate the bolt 32. An auxiliary block 35 is fixedly connected to one side of the mounting plate 33, and the dimension of the auxiliary block 35 on the side away from the mounting plate 33 is smaller than the dimension on the other side. By using the auxiliary block 35, the dimension of one side of the mounting plate 33 is reduced, making it easier for the mounting plate 33 to be inserted into the square tube 31.
[0036] Working principle: When using the electric spark testing device for non-destructive testing, the probe 7 is connected to the main unit 1 via cable 6. At this time, the anti-winding device 2 is used to wind up and limit the unused part of the cable 6. One end of the grounding wire 9 is connected to the main unit 1, and the other end is connected to the object being tested. Then, the probe 8 is connected to one side of the probe. Next, the main unit 1 is turned on by button 4, and the voltage is adjusted by knob 5. Then, the probe 8 is brought into contact with the object being tested to perform metal surface testing. When using cable 6, the limiting plate 24 can be moved away from the take-up column 25. At this time, the spring 23 on one side of the fixing plate 22 deforms, and the unused part of cable 6 is then wound onto the take-up column 25 on the side of the placement plate 21. Then the limiting plate 24 is released, and the spring 23 returns to its original position, causing the limiting plate 24 to contact the take-up column 25. The limiting plate 24 then limits the upper end of the take-up column 25, preventing the cable 6 wound on the take-up column 25 from detaching. By using the anti-tangling device 2, the unused part of cable 6 can be wound and limited, preventing the unused part of cable 6 from moving and tangling when the probe 7 moves, which would affect the subsequent storage and use of cable 6. This facilitates the subsequent storage and use of the electric spark detector, thereby improving the performance of the electric spark detector.
[0037] When using the anti-entanglement device 2, the placement plate 21 can be moved so that the mounting plate 33 on one side of the placement plate 21 is inserted into the square tube 31. Then, the bolt 32 is rotated so that the bolt 32 passes through the square tube 31 and is fixed to the mounting plate 33. Then the position of the placement plate 21 is fixed. By using the mounting component 3, the anti-entanglement device can be quickly fixed, which makes it convenient for operators to use the anti-entanglement device in the future.
