Description

Technical Field

[0001] The present invention relates to the technical field of magnet testing, and particularly to a tooling for cold screen cold shock testing. Background Art

[0002] Cold screen cold shock testing is used to verify the reliability of the cold screen weld area under alternating temperatures. Through three cycles of room temperature - cold shock - temperature recovery, it is inspected whether the weld will peel off from the base material structure. If peeling occurs, it is determined that the cold screen welding area is unqualified and needs to be returned to the factory for repair welding; if no peeling occurs, it is determined that the cold screen welding area is qualified and the next step of work can be carried out. The cold shock source uses liquid nitrogen with the same temperature as the controlled cold screen working environment temperature.

[0003] In the existing cold screen cold shock, the cold screen is mainly placed on the ground, and a handheld liquid nitrogen pipeline is used for cold shocking the cold screen weld.

[0004] However, the existing cold shock methods mainly have two problems: one is that in order to ensure that the cold screen weld is low enough during the cold shock process, it is necessary to maintain the same posture for a long time during the operation of personnel, and it is easy for personnel to get tired; the other is that there is a risk of frostbite for the handheld liquid nitrogen pipeline. Summary of the Invention

[0005] The present invention provides a tooling for cold screen cold shock testing, which can solve the technical problems in the prior art.

[0006] The present invention provides a tooling for cold screen cold shock testing, wherein the tooling includes a frame, a first gear, a rack, a fixture, a rolling table, a second gear, a gear shaft, a conveyor belt, a first rotating unit, a sliding table, a second rotating unit, a slide rail, a cross - moving table, and a second fixing unit. Among them,

[0007] The gear shaft, the first rotating unit, the second rotating unit, and the slide rail are fixed to the upper part of the frame. The second gear is arranged on the gear shaft. By rotating the first rotating unit, the second gear is driven to drive the conveyor belt to move. The movement of the conveyor belt drives the sliding table to move along the slide rail. An opening groove is provided below the sliding table. The cross - moving table is connected to the sliding table through the opening groove. By rotating the second rotating unit, the first gear is driven to drive the rack extending from the cross - moving table to move along the opening groove. The second fixing unit restricts the position of the first gear to ensure that the first gear moves with the sliding table. A fixture is provided below the cross - moving table for fixing the liquid nitrogen cold pipe;

[0008] The rolling table is arranged at the bottom of the frame and includes a plurality of rolling shafts and a first fixing unit. The plurality of rolling shafts are fixed through the first fixing unit. The cold screen is placed on the rolling shafts, and the rolling of the rolling shafts drives the cold screen to move so as to push the cold screen to the cold shock position.

[0009] Preferably, the frame includes multiple groups of square - shaped beams, and the multiple groups of square - shaped beams are welded to form the frame.

[0010] Preferably, the first fixing unit and the second fixing unit are fixing plates.

[0011] Preferably, the opening groove is a dovetail groove.

[0012] Preferably, the conveyor belt is a rubber belt.

[0013] Preferably, the first rotating unit and the second rotating unit are hand wheels.

Among them,

[0023] The gear shaft 8, the first rotating unit 10, the second rotating unit 12, and the slide rail 13 are fixed to the upper part of the frame 1. The second gear 7 is arranged on the gear shaft 8. By rotating the first rotating unit 10, the second gear 7 is driven to drive the conveyor belt 9 to move. The movement of the conveyor belt 9 drives the sliding table 11 to move along the slide rail 13. An opening groove is provided below the sliding table 11. The transverse moving table 15 is connected to the sliding table 11 through the opening groove. By rotating the second rotating unit 12, the first gear 2 is driven to drive the rack 3 extended by the transverse moving table 15 to move along the opening groove. The second fixing unit 16 restricts the position of the first gear 2 to ensure that the first gear 2 moves with the sliding table 11. A fixture 4 is provided below the transverse moving table 15 for fixing the liquid nitrogen cold tube;

[0024] The rolling table is arranged at the bottom of the frame 1 and includes a plurality of rolling shafts 5 and a first fixing unit 6. The plurality of rolling shafts 5 are fixed by the first fixing unit 6. The cold screen 14 is placed on the rolling shafts 5, and the rolling of the rolling shafts 5 drives the cold screen 14 to move so as to push the cold screen 14 to the cold shock position.

[0025] Among them, by adjusting the first rotating unit and the second rotating unit, the position of the liquid nitrogen cold tube can be conveniently and quickly adjusted.

[0026] Through the above technical solution, the position of the liquid nitrogen cold tube (that is, the direction of the liquid nitrogen tube head) can be conveniently adjusted, and the rolling shafts arranged by machining can conveniently send the cold screen to the cold shock position (that is, the position of the liquid nitrogen cold tube), thereby improving the cold shock reliability, reducing personnel fatigue and avoiding frostbite.

[0027] According to an embodiment of the present invention, the frame 1 includes multiple groups of square-shaped beams, and the multiple groups of square-shaped beams are welded to form the frame 1.

[0028] According to an embodiment of the present invention, the first fixing unit 10 and the second fixing unit 16 are fixing plates.

[0029] According to an embodiment of the present invention, the opening groove is a dovetail groove.

[0030] According to an embodiment of the present invention, the conveyor belt 9 is a rubber belt.

[0031] According to an embodiment of the present invention, the first rotating unit 10 and the second rotating unit 12 are handwheels.

[0032] According to an embodiment of the present invention, the rolling shaft 5 is a roller.

[0033] The following describes a tooling for cold screen cold shock test according to the present invention with reference to examples.

[0034] Continue to refer to Figure 1 and 2 , multiple groups of square-shaped beams are welded to form the frame 1 of the tooling. The gear shaft 8, the handwheel 10, the handwheel 12 and the slide rail 13 are fixed on the upper part of the frame 1. By rotating the handwheel 10, the gear 7 can be driven to drive the rubber belt 9 to move, and then drive the sliding table 11 to move along the slide rail 13. A dovetail groove is arranged below the sliding table 11, and a transverse movement table 15 is arranged below the dovetail groove. By rotating the handwheel 12, the gear 2 can be driven to drive the rack 3 extending from the transverse movement table 15 to move along the dovetail groove. The fixing plate 16 limits the position of the gear 2 to ensure that the gear 2 moves with the sliding table 11. A clamp 4 is arranged below the transverse movement table for fixing the liquid nitrogen cold tube. A rolling table is arranged at the bottom of the frame. The rolling table is composed of a fixing plate 6 and rollers 5. By placing the cold screen 14 on the rollers 5, the cold screen 14 can be conveniently pushed to the cold shock position. By adjusting the handwheel 10 and the handwheel 12, the position of the liquid nitrogen cold tube can be conveniently adjusted.

[0035] More specifically, the transverse moving table 15 and the sliding table 11 are connected by a dovetail groove. The gear 2 is fixed to the fixed plate 16 and cooperates with the rack 3 of the transverse moving table 15. The whole is installed on the slide rail 13, and the rubber belt 9 is connected to the gear 7. The hand wheels 10 and 12 are assembled. During the movement, the gear 2 can longitudinally slide along the rotating shaft of the hand wheel 12, which is consistent with the path of the slide rail 13. The roller 5 is fixed inside the fixed plate 6 and then fixedly connected to the frame 1 by bolts. The liquid nitrogen cooling pipe is fixed to the fixture 4.

[0036] By rotating the hand wheel 10, the sliding table 11 can be driven to move along the slide rail. By rotating the hand wheel 12, the rack 3 can be driven to drive the transverse moving table 15 to move horizontally along the dovetail groove under the sliding table 13. The movements in the two directions do not interfere with each other. Through the movements in the two directions, the fixture 4 is driven to move along the weld of the cold shield 14.

[0037] Thus, the position of the liquid nitrogen cooling pipe can be conveniently adjusted, and the cold shield can be sent to the position of the liquid nitrogen cooling pipe through the roller for the cold shock test. This tooling can reduce personnel fatigue, avoid frostbite, and improve the reliability of the cold shock test.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0039] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the spatial relative descriptions used here.

[0040] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the scope of protection of the present invention.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
