Technical Field

[0001] The utility model relates to the technical field of inspection tooling, in particular to an inspection tooling for a mutual inductor contact plate. Background Art

[0002] The contact plate is an important conductive component in the current transformer. Most of them are rectangular plate structures with through holes provided thereon as needed. The outer dimensions of the contact plate and the size and position of the through holes provided thereon vary depending on the model of the current transformer.

[0003] During the production process, inspectors need to check the external dimensions and the size and position of the through holes of each contact plate. For example, Chinese patent publication number "CN214537640U" discloses an inspection device for current transformer contact plates, which includes a first shell, the upper surface of which is evenly fixedly connected to a vertical pole, the outer side wall of the vertical pole is sleeved with a first sleeve, the outer side wall of the first sleeve is fixedly connected to a second shell, the inner side wall of the second shell is slidably connected to a third shell, the inner side wall of the fifth shell is slidably connected to a second sleeve, the inner side wall of the fifth shell is threadedly connected to a threaded rod, the top of the threaded rod is rotatably connected to the bottom of the second sleeve through a bearing, and the bottom of the threaded rod is fixedly connected to a first knob.

[0004] During the production process of contact plates, inspectors need to use testing tools to measure the external dimensions, size and position of each contact plate separately. Testing one by one is not only inefficient, but also prone to errors in the data, which greatly reduces the speed of inspection and increases the labor intensity of staff. Utility Model Content

[0008] Furthermore, the limiting mechanism includes at least four limiting holes, which are opened on the surface protruding from the outside of the rotating table. A horizontal plate is fixed on one side of the placement box, and a through hole is opened on the surface of the horizontal plate. A pin is movably connected between the through hole and the limiting hole.

[0009] Furthermore, the clamping mechanism includes a guide frame, which is fixed to the surface of the rotating table. The inner side of the guide frame is slidably connected to a clamping block, which is clamped to the inspection device. A guide column is fixed to the inner side of the guide frame, which is slidably connected to the clamping block. The surface of the guide column is provided with a first spring and the two ends of the first spring are respectively in contact with the guide frame and the clamping block.

[0010] Furthermore, limiting blocks are fixed on both sides of the clamping block, and guide grooves are provided on both sides of the guide frame, and the limiting blocks are slidably connected to the guide grooves.

[0011] Furthermore, the rebound mechanism includes a slide groove, which is arranged on both sides of the inspection groove. A rebound block is slidably connected to the inner side of the inspection groove, and a second spring is fixed between the rebound block and the slide groove.

[0012] Furthermore, a positioning groove is provided on the inner side of the slide groove, and positioning blocks are fixed on both sides of the rebound block, and the positioning blocks are slidably connected to the positioning groove.

[0013] The utility model proposes an inspection tool for the contact plate of a mutual inductor, which has the beneficial effects that: the utility model can place the contact plate for inspection through the inspection slot, and can quickly determine whether the size of the contact plate is normal.

At least four placing slots 5 are provided on the surface of said rotating table 3, and an inspection tool 6 is movably connected with the inner side of said placing slot 5, and a clamping mechanism 7 is provided between said inspection tool 6 and rotating table 3. An inspection slot 8 is provided on the surface of said inspection tool 6, and a rebound mechanism 9 is provided on both sides of said inspection slot 8; the inspection tool can place the contact plate for inspection through the inspection slot 8, and can quickly judge whether the size of the contact plate is normal. The rebound blocks 92 on both sides reset and bounce the contact plate under the action of the second spring 93, so as to quickly remove the contact plate, and the inspection tool 6 can be conveniently and quickly disassembled for replacement. At the same time, four inspection tools 6 of different sizes can conveniently inspect contact plates of various sizes, greatly improving the inspection efficiency while ensuring the inspection of contact plates of different sizes.

[0021] In this embodiment, the limiting mechanism 4 includes at least four limiting holes 41, and the angle of the four limiting holes 41 is 90 degrees. The limiting holes 41 are opened on the surface protruding from the outside of the rotating table 3. A horizontal plate 42 is fixed on one side of the placement box 2, and a through hole 43 is opened on the surface of the horizontal plate 42. A pin 44 is movably connected between the through hole 43 and the limiting hole 41. The pin 44 can limit the rotating table 3 by 90 degrees, making it convenient to rotate the rotating table 3.

[0022] Furthermore, the clamping mechanism 7 includes a guide frame 71, which is fixed to the surface of the rotating table 3. The inner side of the guide frame 71 is slidably connected with a clamping block 72, and the clamping block 72 is clamped with the inspection device 6. A guide column 73 is fixed on the inner side of the guide frame 71, and the guide column 73 is slidably connected with the clamping block 72. The surface of the guide column 73 is provided with a first spring 74 and the two ends of the first spring 74 are respectively in contact with the guide frame 71 and the clamping block 72. The clamping block 72 can clamp the inspection device 6 for easy replacement.

[0023] Furthermore, limiting blocks 10 are fixed on both sides of the clamping block 72, and guide grooves 11 are provided on both sides of the guide frame 71.
