The end of the powder blowing piece 3 close to the workpiece 2 is of a tubular structure, a channel for conveying air flow is formed in the powder blowing piece, one end of the powder blowing piece 3 is closed, and the other end of the powder blowing piece is communicated with an external air source. A plurality of air outlets 311 are formed in the pipe wall of the powder blowing piece 3, the air outlets 311 are distributed on the powder blowing piece 3 at intervals, and the air outlets 311 face the outer surface of the workpiece 2.
When the workpiece 2 is detected, the workpiece 2 is demagnetized, and at the moment, the magnetic powder attached to the workpiece 2 needs to be cleaned, the workpiece 2 is driven to rotate relative to the powder collecting cylinder 1, the powder blowing piece 3 slides along the horizontal direction and the direction parallel to the axis of the powder collecting cylinder 12 under the action of an external driving mechanism (such as a driving matching mode of a motor and a screw rod in the prior art), meanwhile, an external air source conveys air flow into the powder blowing piece 3, the air flow is sprayed to the outer surface of the workpiece 2 through the air outlet 311, the residual magnetic powder on the outer surface of the workpiece 2 is blown, the magnetic powder falls into the powder collecting cylinder 1 to be collected, and the cleaning can be realized by utilizing the powder blowing piece 3 by utilizing the good fluidity of the air flow even if the magnetic powder remains in the defect of the outer surface of the workpiece 2.
The powder collecting cylinder 1 is provided with an upward opening, the cross section of the powder collecting cylinder is formed into a U shape, the powder collecting cylinder can effectively cover the workpiece 2 from bottom to top, a collecting space is provided for falling magnetic powder, the magnetic powder is prevented from scattering into the surrounding environment, and the collecting efficiency of the magnetic powder is improved. The powder blowing piece 3 slides along the horizontal direction, and the sliding direction is parallel to the axis of the powder collecting cylinder 1, and the powder blowing piece 3 can cover the whole outer surface of the workpiece 2 by combining the stepping rotation of the workpiece 2, so that the comprehensiveness of magnetic powder cleaning is ensured. The air flow blown by the air outlet 311 can directly act on the outer surface of the workpiece 2 to blow off the residual magnetic powder, so that the problem that the magnetic powder is easy to remain at the surface defect of the workpiece 2 in the prior art is effectively solved, and the waste of the magnetic powder is reduced. Meanwhile, the air flow blown by the powder blowing piece 3 can effectively clean the residual magnetic powder in the defect part, so that the cleaning effect is improved. The powder blowing piece 3 and the powder collecting barrel 1 are matched to form a complete magnetic powder cleaning and collecting system, so that the recovery rate of magnetic powder is improved, the detection cost is reduced, the influence of residual magnetic powder on the subsequent surface processing of the workpiece 2 is avoided, and the processing quality of the workpiece 2 is ensured.
In some examples, the structure of the electrode roller detection device is refined, for example, as shown in fig. 1-2 and fig. 5-8, a powder blowing part 3 of the workpiece 2 detection device is composed of a plurality of air outlet pipes 31 and a plurality of connecting components 32, and one connecting component 32 is connected between any two adjacent air outlet pipes 31. The air outlet pipe 31 is of a tubular structure, and an air outlet 311 for blowing air flow is formed in the pipe wall.
The connecting assembly 32 comprises a first hinge seat 321 and a second hinge seat 322 which are mutually hinged, wherein the first hinge seat 321 and the second hinge seat 322 are respectively provided with a first stress part 3211 and a second stress part 3221, a hinge shaft between the first hinge seat 321 and the second hinge seat 322 is positioned at one side close to the outer circumferential surface of the workpiece 2, the first stress part 3211 and the second stress part 3221 are respectively positioned at one side, away from the workpiece 2, of the first hinge seat 321 and the second hinge seat 322, namely along the direction extending towards the outer circumference of the workpiece 2, the hinge shaft between the first hinge seat 321 and the second hinge seat 322 is closer to the workpiece 2 than the first stress part 3211 and the second stress part 3221, and the first hinge seat 321 and the second hinge seat 322 are respectively fixedly connected with two adjacent air outlet pipes 31. The deformation sleeve 323 is sleeved on the peripheries of the first hinge seat 321 and the second hinge seat 322, and two ends of the deformation sleeve are respectively and hermetically connected with the two adjacent air outlet pipes 31. The deformation sleeve 323 and two adjacent air outlet pipes 31 enclose to form a deformation chamber 324, and the deformation chamber 324 is communicated with a channel built in the air outlet pipe 31. The deformation chamber 324 is used for communicating two adjacent air outlet pipes 31.
When external high-pressure air flow is input into the deformation chamber 324, the air flow in the deformation chamber 324 flows into the air outlet pipe 31 communicated with the deformation chamber 324, and simultaneously the air flow can also cause air impact on the first stressed part 3211 on the first hinge seat 321 and the second stressed part 3221 on the second hinge seat 322, under the impact action of the air flow, the first stressed part 3211 and the second stressed part 3221 relatively rotate in opposite directions further drive the first hinge seat 321 and the second hinge seat 322 to rotate in opposite directions by taking the hinge shaft as the center, and finally the first hinge seat 321 and the second hinge seat 322 relatively far away drive the air outlet pipes 31 at two ends of the deformation sleeve 323 to be close to the periphery of the workpiece 2, and finally the air outlet pipe 31 is close to and attached to the outer periphery of the workpiece 2. The whole powder blowing part 3 is bent and deformed and is matched with the outer circumference of the workpiece 2. During this process, the deformation sleeve 323 may deform to accommodate the overall bending deformation of the outlet tube 31.
Through the modularized combined structure of the air outlet pipe 31 and the connecting component 32, the powder blowing piece 3 can be self-adaptively adjusted according to the outer circumferential shape of the workpiece 2, so that the air outlet pipe 31 is tightly attached to the outer surface of the workpiece 2, and the pertinence and the effectiveness of air flow blowing are improved. Meanwhile, the device is applicable to workpieces 2 with different diameters, and the application range of the detection device is enlarged.
The articulated design of the first articulated seat 321 and the second articulated seat 322 in the connecting assembly 32 is matched with the pressure driving generated after the deformation cavity 324 receives air flow, so that the adjacent air outlet pipes 31 can automatically rotate relatively towards the direction close to the workpiece 2, the attachment of the powder blowing piece 3 and the workpiece 2 can be realized without an additional mechanical transmission structure, and the device structure is simplified. The setting of deformation sleeve 323 when guaranteeing deformation cavity 324 sealed, allows taking place relative rotation between two adjacent outlet duct 31, ensures that the air current does not take place to leak at the transmission in-process, has guaranteed simultaneously that outlet duct 31 is at stability and the reliability of rotation in-process, effectively avoids blowing powder piece 3 and work piece 2 surface to have great clearance the magnetic powder to sweep incomplete problem that leads to, further promotes magnetic powder cleaning efficiency and effect.
In some examples, the structure of the electrode roller detecting device is refined, for example, as shown in fig. 1-2 and fig. 5-8, the connecting component 32 of the workpiece 2 detecting device includes a connecting piece 325 sleeved on the periphery of the air outlet pipe 31, the connecting piece 325 is in an annular structure, and the inner wall of the connecting piece 325 is fixedly connected with the outer wall of the air outlet pipe 31. The rotating ring 326 is rotatably provided on the outer periphery of the connecting piece 325, and the axis of the rotating ring 326 is perpendicular to the axis of the work 2. When the first hinge seat 321 and the second hinge seat 322 are impacted by air flow to rotate in a deviating way, the outer circumferential surface of the rotating ring 326 is in rolling contact with the outer circumferential surface of the workpiece 2, and the rotating ring 326 rolls along the outer surface of the workpiece 2.
The connecting piece 325 fixes the rotating ring 326 to the outer periphery of the air outlet pipe 31, so that the rotating ring 326 moves synchronously with the powder blowing piece 3. The rolling connection mode of the rotating ring 326 and the outer surface of the workpiece 2 converts sliding friction when the powder blowing piece 3 slides into rolling friction, reduces mechanical abrasion between the powder blowing piece 3 and the workpiece 2, prolongs the service life of equipment, and can avoid secondary damage to the outer surface of the workpiece 2. The rotating ring 326 forms a supporting and guiding function on the powder blowing piece 3 in the rolling process, ensures that the powder blowing piece 3 stably slides along the axial direction of the workpiece 2, avoids the sweeping position deviation caused by uneven friction resistance, ensures that the air outlet 311 always aims at the surface area to be cleaned of the workpiece 2, and improves the uniformity and reliability of magnetic powder sweeping.
In some examples, the structure of the electrode roller detection device is refined, for example, as shown in fig. 1-2 and fig. 5-8, a bellows is selected as a deformation sleeve 323 of the workpiece 2 detection device, the bellows is sleeved on the peripheries of the hinge seat one 321 and the hinge seat two 322, and two ends of the bellows are respectively connected with ports of two adjacent air outlet pipes 31 in a sealing manner. The fold structure of the corrugated pipe extends along the axial direction of the corrugated pipe, the outer peripheral surface of the fold structure is attached to the outer peripheral surfaces of the first hinge seat 321 and the second hinge seat 322, and when the first hinge seat 321 and the second hinge seat 322 rotate in the direction deviating from each other, the fold structure of the corrugated pipe is elastically deformed to adapt to the rotation angle change of the adjacent air outlet pipe 31, and meanwhile the tightness of the deformation cavity 324 is maintained.
The corrugated pipe is adopted as the deformation sleeve 323, and the axial fold structure of the corrugated pipe can generate elastic deformation when the hinge seat rotates, so that the rotation angle of the adjacent air outlet pipe 31 can be flexibly adjusted, and the compact attachment of the powder blowing piece 3 to the outer circumferential surface of the workpiece 2 is ensured. The elastic sealing characteristic of the bellows can effectively prevent air flow leakage in the deformation chamber 324, and ensure that air flow pressure stably pushes the first hinge seat 321 and the second hinge seat 322 to rotate relatively, so that the powder blowing piece 3 is self-adaptively attached to the curved surface of the workpiece 2. Compared with the traditional rigid sleeve, the sleeve cracking or air leakage problem caused by the rotation of the air outlet pipe 31 is avoided due to the deformability of the corrugated pipe, the reliability and durability of the device are improved, meanwhile, the continuous and stable air flow in the magnetic powder blowing process is ensured, the residual magnetic powder on the surface of the workpiece 2 is effectively removed, the magnetic powder waste is reduced, and the influence on the subsequent processing is avoided.
In some examples, the structure of the electrode roller detection device is refined, for example, as shown in fig. 1-2 and 5-12, the powder distribution unit 4 of the workpiece 2 detection device includes a powder storage bin 41, chu Fencang, 41 slidably disposed above one side of the powder collecting cylinder 1 in the horizontal direction. The powder storage bin 41 has a material distributing member 42 extending downward to a side close to the powder collecting cylinder 1, the material distributing member 42 is flat, a passage for transporting magnetic powder is formed inside the material distributing member 42, a material distributing port 421 for outputting magnetic powder is formed at a lower end of the material distributing member 42, and the material distributing port 421 is a flat port.
When the magnetic powder inspection of the workpiece 2 is performed, chu Fencang 41 drives the material distributing part 42 to approach the workpiece 2 under the action of the external driving mechanism. The workpiece 2 rotates relative to the powder collecting cylinder 1, the magnetic powder in Chu Fencang enters the channel of the material distributing member 42 through the material discharging port, and is output from the material distributing port 421 and is scattered on the outer circumferential surface of the workpiece 2.

The downward inclination of the distributing member 42 enables the magnetic powder to be naturally output from the distributing port 421 by the action of gravity, without an additional power device, simplifying the structure. The arrangement of the cloth port 421 enables the magnetic powder to be scattered on the outer surface of the workpiece 2 in a concentrated mode, so that the utilization rate of the magnetic powder is improved, and the waste of the magnetic powder is reduced. The powder distribution unit 4 and the powder collection cylinder 1 are matched for use, so that the magnetic powder inspection and detection process is more efficient and convenient, and good conditions are provided for subsequent magnetic powder cleaning and detection result observation.
In some examples, the structure of the electrode roller detection device is refined, for example, as shown in fig. 1-2 and fig. 5-12, in the powder distribution unit 4 of the workpiece 2 detection device, the distribution port 421 is long and the extending direction is parallel to the axis of the workpiece 2. The amplitude modulation member 43 is in a long bar-shaped/sheet-shaped structure, one end of the amplitude modulation member 43 is arranged in the material distributing member 42 in a swinging way through a pin shaft, and the swinging axis of the amplitude modulation member 43 is perpendicular to the moving direction of the magnetic powder in the material distributing member 42. The amplitude modulation seat 44 is disposed on the outer sidewall of the material distributing member 42, and a plurality of clamping slots 441 are disposed on the amplitude modulation seat 44 and sequentially arranged along the length direction of the material distributing member 42. The connecting rod 45 is located above the amplitude modulation seat 44, one end of the connecting rod 45 is hinged with one end of the amplitude modulation piece 43 away from the pin shaft, and the other end of the connecting rod 45 is provided with a clamping column 451 which is in clamping fit with the clamping groove 441. A limit bar 46 is arranged above the amplitude modulation base 44, and a limit gap 47 for the connecting rod 45 to pass through is formed between the limit bar 46 and the amplitude modulation base 44.
When the cloth width of the cloth opening 421 needs to be adjusted, the connecting rod 45 is pulled to separate the clamping column 451 from the current clamping groove 441, then the amplitude modulation piece 43 is swung, the swinging of the amplitude modulation piece 43 drives the connecting rod 45 to slide in the limiting gap 47, and after the amplitude modulation piece 43 swings to a proper position, the connecting rod 45 is pushed to enable the clamping column 451 to be clamped into the corresponding clamping groove 441, so that the relative position between the amplitude modulation piece 43 and the connecting rod 45 is fixed, and the adjustment of the cloth width of the cloth opening 421 is realized.
The design of rectangular form cloth mouth 421 for the magnetic powder can be in the axial direction of work piece 2 evenly unrestrained, has improved the homogeneity that the magnetic powder covered. The swing setting of the amplitude modulation piece 43 can adjust the width of cloth of the cloth opening 421 according to workpieces 2 with different specifications, so that the universality and the adaptability of the device are enhanced. The clamping groove 441 on the amplitude modulation seat 44 is matched with the clamping column 451 on the connecting rod 45 in a clamping way, so that a plurality of fixing positions are provided for the amplitude modulation piece 43, and the width adjustment of the cloth at the cloth opening 421 is more accurate and stable. The limiting gap 47 formed between the limiting strip 46 and the amplitude modulation seat 44 plays a role in guiding and limiting the sliding of the connecting rod 45, ensures that the connecting rod 45 cannot deviate in the sliding process, and ensures the stability and reliability of the swing of the amplitude modulation piece 43.

In some examples, the structure of the electrode roller detection device is refined, for example, as shown in fig. 1 to 4, the impurity removing unit 5 of the workpiece 2 detection device includes an impurity removing rod 51, the impurity removing rod 51 is slidably disposed on a side wall of the powder collecting barrel 1, and a sliding direction of the impurity removing rod 51 is perpendicular to an axis of the powder collecting barrel 1. The impurity removing member 52 is provided at one end of the impurity removing rod 51 near the workpiece 2, the impurity removing member 52 has a cleaning portion 521 for cleaning magnetic powder, the cleaning portion 521 has a brush structure, and bristles of the brush face the outer surface of the workpiece 2. The limiting wheel 53 is rotatably arranged on the impurity removing rod 51 through a pin shaft and positioned on the upper side or the lower side of the impurity removing piece 52, and the axis of the limiting wheel 53 is parallel to the axis of the powder collecting barrel 1.
When the magnetic powder on the surface of the workpiece 2 is cleaned, the impurity removing rod 51 slides in the horizontal direction under the action of the external driving mechanism, and drives the limiting wheel 53 and the impurity removing member 52 to be close to the workpiece 2. The limiting wheel 53 rolls against the outer circumferential surface of the workpiece 2, and plays a role in supporting and guiding the impurity removing rod 51, so that the impurity removing rod 51 maintains a stable sliding state. At the same time, the bristles of the cleaning part 521 are in light contact with the outer circumferential surface of the workpiece 2, and the cleaning part 521 cleans the magnetic powder on the outer circumferential surface of the workpiece 2 along with the rotation of the workpiece 2, at this time, the workpiece 2 is not demagnetized, if the surface of the workpiece is defective, the magnetic powder adsorbed at the defect is not cleaned by the cleaning part 521, the magnetic powder attached to other parts of the workpiece 2 is cleaned by the cleaning part 521, and the dropped magnetic powder falls into the powder collecting cylinder 1 to be collected.
The brush structure design of the cleaning part 521 can effectively clean the magnetic powder attached to the outer surface of the workpiece 2 and avoid damaging the surface of the workpiece 2, because the impurity removing rod 51 slides along the horizontal direction and is close to or far away from the axis of the powder collecting cylinder 1 after sliding. The spacing wheel 53 is arranged, so that the impurity removing rod 51 can keep a stable distance with the workpiece 2 in the sliding process, the moderate contact strength between the cleaning part 521 and the outer surface of the workpiece 2 is ensured, the cleaning effect is ensured, and excessive abrasion of bristles or scraping of the surface of the workpiece 2 caused by too tight contact can be avoided. Meanwhile, the arrangement of the limiting wheels 53 ensures that the contact force between the cleaning part 521 and the outer surface of the workpiece 2 is moderate, so that the adsorbed magnetic powder at the defect can not be completely cleaned, and other non-adsorbed magnetic powder on the workpiece 2 can be cleaned, and after the impurity removal of the impurity removal piece 52, whether the surface of the workpiece 2 has defects and the positions of the defects can be better confirmed, and through secondary observation, the erroneous judgment of the defects is prevented, and the accuracy of the detection result is improved.

The sliding direction of the pin 54 is generally perpendicular or parallel to the axial direction of the powder collecting barrel 1.
When the magnetic powder on the surface of the workpiece 2 is cleaned, the lock pin 54 is firstly slid to separate from the pin hole 511 of the impurity removing rod 51, and the impurity removing rod 51 slides in the direction approaching the workpiece 2 under the action of the elastic member 55 until the limit wheel 53 rolls and abuts against the outer circumferential surface of the workpiece 2 and the cleaning part 521 is in light contact with the outer circumferential surface of the workpiece 2. During the rotation of the workpiece 2, the cleaning portion 521 cleans the outer circumferential surface of the workpiece 2 with magnetic powder.
The elastic member 55 provides an active force to the impurity removing lever 51 to approach the workpiece 2, so that the cleaning portion 521 can be adaptively attached to the outer surface of the workpiece 2, and the cleaning effect can be ensured even if the workpiece 2 has a certain dimensional deviation or uneven surface. The cooperation of the pin holes 511 and the lock pins 54 realizes accurate locking of the positions of the impurity removing rods 51, ensures that the relative positions of the impurity removing rods 51 can be locked when the operation is not performed, and prevents interference to the removal and the movement of the workpiece 2. The structural design ensures the stability of the impurity removing rod 51 in the cleaning process, gives a certain self-adaptive adjustment capability to the impurity removing rod, effectively solves the problem that residual magnetic powder is not thoroughly cleaned, reduces the damage risk to the surface of the workpiece 2 due to improper interference pressure, and improves the reliability and service life of the detection device.
