Description

[0002] For some precision long-length cylindrical parts (such as pipes, rods or shafts, etc.), magnetic particle testing is usually required before they are put into use to determine whether there is any damage on the outer surface of the long-length cylindrical parts that affects their use. The general process of magnetic particle testing is as follows: first spray a layer of magnetic suspension on the surface of the long-length cylindrical parts, and then use a magnetic particle flaw detector to test the surface of the long-length cylindrical parts.

[0003] When spraying magnetic powder, in order to avoid serious damage caused by friction between the outer circumference of long cylindrical parts and the cement floor, long cylindrical parts are usually not placed flat on the ground, but placed upright. However, the long cylindrical parts placed upright are relatively high, and the staff must step on the raising device to spray the upper part of the long cylindrical parts; and the staff also need to constantly change the position of the raising device to facilitate the staff to fully spray the outer circumference of the upper part of the long cylindrical parts. In addition, in order to prevent the long cylindrical parts placed upright from tipping over and causing safety accidents, auxiliary support devices will be installed to fix the long cylindrical parts on the ground and then removed after spraying.

[0033] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention, rather than to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0034] like Figures 1 to 3As shown, the present invention provides a magnetic particle detection clamping tool, which includes a guide device 1, a first clamping device 2, a second clamping device 3 and a supporting device 4, wherein the first clamping device 2 and the second clamping device 3 are spaced apart along the length direction of the guide device 1. The first clamping device 2 includes a first driving mechanism 21 and a first clamping mechanism 22, wherein the first driving mechanism 21 is fixedly mounted on the guide device 1, and the first clamping mechanism 22 is fixedly mounted on the first driving mechanism 21, and the first driving mechanism 21 can drive the first clamping mechanism 22 to rotate circumferentially. The second clamping device 3 includes a second driving mechanism 31 and a second clamping mechanism 32, the second driving mechanism 31 is fixedly mounted on the guide device 1, the second clamping mechanism 32 is rotatably mounted on the second driving mechanism 31, the second driving mechanism 31 can drive the second clamping mechanism 32 to move linearly in the length direction of the guide device 1, the axis of the second clamping mechanism 32 coincides with the axis of the first clamping mechanism 22 and both extend along the length direction of the guide device 1, and the second clamping mechanism 32 and the first clamping mechanism 22 can be horizontally clamped at both ends of the axial direction of the long-length cylindrical component 7. The supporting device 4 is located between the first clamping mechanism 22 and the second clamping mechanism 32 and is used to support the long-length cylindrical component 7.

[0035] Specifically, the worker can lift the long-length cylindrical component 7 between the first clamping mechanism 22 and the second clamping mechanism 32, and place the long-length cylindrical component 7 on the supporting device 4, and then the second driving mechanism 31 drives the second clamping mechanism 32 to move toward the first clamping mechanism 22, so that the circumferential ends of the long-length cylindrical component 7 are clamped by the first clamping mechanism 22 and the second clamping mechanism 32 respectively, and at this time, the axis of the long-length cylindrical component 7 extends along the length direction of the guide device 1, that is, at this time, the long-length cylindrical component 7 is placed horizontally; then the first driving mechanism 21 drives the first clamping mechanism 22 to rotate, and the first clamping mechanism 22 can drive the long-length cylindrical component 7 to rotate circumferentially; then the staff can easily spray the magnetic suspension on the horizontally placed long-length cylindrical component 7. Therefore, the magnetic particle detection clamping tooling of the present invention reduces the difficulty of spraying magnetic suspension for long-length cylindrical components.

[0036] In some embodiments, the support device 4 can be removed to prevent the support device 4 from excessively hindering the rotation of the long-length cylindrical component 7. In other embodiments, the support portion of the support device 4 is provided with a protective cushion layer to prevent friction damage to the long-length cylindrical component 7.

[0037] like Figure 1 to Figure 2As shown, in some embodiments of the present invention, the guide device 1 includes two parallel rails 11, the first drive mechanism 21 and the second drive mechanism 31 are respectively fixedly mounted on both ends of the rails 11 in the length direction thereof, and the support device 4 is located between the two rails 11. The structure of the guide rail is simple, which helps to reduce the manufacturing cost.

[0038] Of course, the guide device 1 may also be any other structural form that can achieve the above technical effects, and the present invention does not limit this.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the guide device 1 also includes a telescopic frame 12, the telescopic frame 12 includes two first sleeves 121 and two first telescopic rods 122, the two first sleeves 121 are fixed between the two rails 11, the two first sleeves 121 are spaced apart in the width direction of the guide device 1, and the axis of the first sleeve 121 extends along the length direction of the guide device 1; the rear sections of the two first telescopic rods 122 are respectively movably arranged in the two first sleeves 121, and the front sections of the first telescopic rods 122 are located outside the corresponding first sleeves 121, the support device 4 is connected to the end of the front section of the first telescopic rod 122, and the outer side of the front section of the first telescopic rod 122 is provided with a first walking wheel 123, the axis of the first walking wheel 123 extends along the width direction of the guide device 1, and the first walking wheel 123 can roll along the rail 11 on the ground. A first connecting tube 124 is provided at the top of the first sleeve 121, and a first limiting rod 125 is threadedly connected to the first connecting tube 124. The top of the first limiting rod 125 is located above the first connecting tube 124, and a first rotating plate 126 is provided at the top of the first limiting rod 125. The bottom end of the first limiting rod 125 can move through the wall of the first connecting tube 124 and can contact the top of the corresponding first telescopic rod 122.

[0040] Specifically, the bottom of the first limiting rod 125 presses against the top of the first telescopic rod 122, so that the first telescopic rod 122 is fixed in the first sleeve 121. When it is necessary to change the length of the first telescopic rod 122 extending out of the first sleeve 121, the first rotating plate 126 is rotated, the first limiting rod 125 moves in a direction away from the first telescopic rod 122, and then the length of the first telescopic rod 122 extending out of the first sleeve 121 is adjusted, and the first walking wheel 123 can reduce the resistance of the first telescopic rod 122 when moving; then the first rotating plate 126 is rotated in the opposite direction, so that the bottom of the first limiting rod 125 presses against the top of the first telescopic rod 122 again, and then the first telescopic rod 122 is re-fixed. By adjusting the length of the first telescopic rod 122 extending out of the first sleeve 121, the position of the supporting device 4 can be adjusted, so as to facilitate the support of the long-length cylindrical component 7.

[0041] like Figures 1 to 3 As shown, in some embodiments of the present invention, the first driving mechanism 21 includes a first driving motor 212 and a transmission shaft 211. The first driving motor 212 is fixedly mounted at the end of the track 11, and the head end of the transmission shaft 211 is connected to the output shaft of the first driving motor 212. The first clamping mechanism 22 includes a first clamping disc 221, which is fixedly connected to the end of the transmission shaft 211. The first driving motor 212 can drive the first clamping disc 221 to rotate circumferentially around its axis through the transmission shaft 211. The axis of the transmission shaft 211, the axis of the first clamping disc 221 and the axis of the second clamping mechanism 32 coincide and extend along the length direction of the guide device 1. The axis of the first clamping disc 221 is located above the guide device 1.

[0042] Specifically, the staff first lifts the long-length cylindrical component 7 between the second clamping mechanism 32 and the first clamping disk 221, and then the second driving mechanism 31 drives the second clamping mechanism 32 to move toward the first clamping disk 221, thereby clamping the long-length cylindrical component 7 between the second clamping mechanism 32 and the first clamping disk 221, and the supporting device 4 supports the long-length cylindrical component 7; then the first driving motor 212 can drive the first clamping disk 221 to rotate circumferentially around its axis through the transmission shaft 211, and the first clamping disk 221 can drive the long-length cylindrical component 7 to rotate axially, thereby facilitating the spraying of the outer circumferential surface of the long-length cylindrical component 7.

[0043] In some embodiments, the first drive mechanism 21 may also include a common gear box, which further includes a box body and a gear transmission mechanism installed in the box body. The box body is fixedly installed at the end of the track 11. The first drive motor 212 is connected to the transmission shaft 211 through the gear transmission mechanism in the box body to drive the transmission shaft 211 to rotate circumferentially.

[0044] Of course, the first driving mechanism 21 and the first clamping mechanism 22 may also be any other structural form that can achieve the above technical effects, and the present invention does not limit this.

[0045] like Figure 1 to Figure 2As shown, in some embodiments of the present invention, the first clamping mechanism 22 further includes an end fixing mechanism, and the end fixing mechanism further includes two fixing blocks 223, two connecting bolts 224 and two clamping blocks 225. The two fixing blocks 223 are respectively fixedly connected to the top surface and the bottom surface of the first clamping disc 221, the two connecting bolts 224 vertically penetrate the two fixing blocks 223, and the connecting bolts 224 are threadedly connected to the corresponding fixing blocks 223, and the two clamping blocks 225 are respectively threadedly connected to the ends of the two connecting bolts 224 so as to be used for radially clamping the ends of the long-length cylindrical component 7, the two clamping blocks 225 are located between the first clamping disc 221 and the second clamping mechanism 32, and the side of the clamping block 225 facing the long-length cylindrical component 7 is set as an arc surface.

[0046] Specifically, after the second clamping mechanism 32 and the first clamping plate 221 axially clamp the long-length cylindrical component 7, the two connecting bolts 224 can be rotated, and the two clamping blocks 225 move toward the long-length cylindrical component 7 until the two clamping blocks 225 clamp the ends of the long-length cylindrical component 7, thereby further fixing the long-length cylindrical component 7 to prevent the long-length cylindrical component 7 from tilting and loosening. Preferably, a rubber layer is provided on one side of the clamping block 225 facing the long-length cylindrical component 7 to prevent the outer peripheral surface of the long-length cylindrical component 7 from being damaged.

[0047] like Figure 1 to Figure 2 As shown, in some embodiments of the present invention, the second driving mechanism 31 includes a first fixed plate 311, a first driving cylinder 312 and a connecting shaft 313. The first fixed plate 311 is fixedly connected to the end of the track 11 and extends vertically. The cylinder body of the first driving cylinder 312 is fixedly connected to the first fixed plate 311, and the driving rod of the first driving cylinder 312 is fixedly connected to the head end of the connecting shaft 313. The second clamping mechanism 32 includes a second clamping disc 321, which is rotatably connected to the end of the connecting shaft 313. The axis of the second clamping disc 321, the axis of the connecting shaft 313, the axis of the first driving cylinder 312 and the axis of the first clamping disc 221 coincide with each other and extend along the length direction of the guide device 1.

[0048] Specifically, the first driving oil cylinder 312 can drive the connecting shaft 313 to move linearly, and the connecting shaft 313 can drive the second clamping plate 321 to move linearly. The second clamping plate 321 is rotatably connected to the end of the connecting shaft 313, so when the second clamping plate 321 and the first clamping plate 221 clamp the long cylindrical component 7, the second clamping plate 321 can rotate circumferentially around its axis under the drive of the first driving motor 212.

[0049] Of course, the second driving mechanism 31 and the second clamping mechanism 32 can also be any other structural form that can achieve the above-mentioned technical effects, and the present invention does not limit it.
