It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a coil measuring device according to an embodiment of the present disclosure, and fig. 2 is a structural schematic diagram of a covering member and a supporting member of the coil measuring device shown in fig. 1 in a separated state. The embodiment of the application provides a coil measuring device, which is used for measuring a coil 600. The coil measuring apparatus may include a holding member 100 and a covering member 200. The holding member 100 has a first curved surface 11, and the first curved surface 11 holds the coil 600. The covering member 200 has a second curved surface 21, and the second curved surface 21 is used to cover the coil 600 held by the holding member 100. The measuring mechanism 300 is used to measure the position of the covering member 200 with respect to the supporting member 100.

It is understood that the coil 600 may include third and fourth curved surfaces opposite in a thickness direction thereof. During the measurement, the third curved surface of the coil 600 may be placed on the first curved surface 11 of the holding member 100, and then the second curved surface 21 of the covering member 200 may be covered on the fourth curved surface of the coil 600. At this time, if the surface profile of the coil 600 or the shape error of the third curved surface and the fourth curved surface is within the allowable range, the measurement structure 300 may measure that the covering member 200 is located at the predetermined position of the supporting member 100, and if the surface profile of the coil 600 or the shape error of the third curved surface and the fourth curved surface is outside the allowable range, the measurement structure 300 may measure that the covering member 200 is not located at the predetermined position of the supporting member 100. Further, the coil measuring apparatus provided in the embodiment of the present application can measure whether or not the surface profile of the coil 600 is correct by testing the relative positions of the holder member 100 and the cover member 200.

In some embodiments, the measuring structure 300 includes at least one of a height gauge, an image measuring device, or a three-axis coordinate measuring device for measuring the distance between the top surface of the cover member 200 and the bottom surface of the support member 100. The relative positions of the support member 100 and the closure member 200 can be determined by the distance between the top surface of the closure member 200 and the bottom surface of the support member 100.

Taking the example where the measuring structure 300 includes a height gauge, the coil measuring device may include a table 400, and the height gauge and the support member 100 are both fixedly disposed on the table 400. Then, after the cover member 200 is closed to the seating member 100, the height gauge probe may abut against the top surface of the cover member 200 to measure the distance between the top surface of the cover member 200 and the bottom surface of the seating member 100.

Of course, in some other embodiments, the height gauge may be directly fixed to the supporting member 100, or the supporting member 100 may be fixed to a base of the height gauge, which is not limited in the examples of the present application.

Taking the example that the measurement framework includes the image measuring instrument, the image measuring instrument may be a CCD image measuring instrument or an OMM image measuring instrument, which is not limited in this application.

Of course, in some other embodiments, the measuring mechanism 300 may be a scale or the like provided on the support member 100, and the position of the covering member 200 with respect to the support member 100 may be measured by measuring the distance from the specific position of the covering member 200 to the support member 100, and it may be determined whether or not the surface contour shape of the coil 600 is correct.

Referring to fig. 3, fig. 3 is a schematic view illustrating a second structure of a coil measuring device according to an embodiment of the present disclosure. Alternatively, the measuring structure 300 is provided on the holding member 100. The measuring structure 300 includes at least one of a micro switch, a distance sensor, and a pressure sensor movably engaged with the covering member 200. Furthermore, when the covering member 200 covers the supporting member 100, the covering member 200 may trigger the micro switch, the distance sensor, or the pressure sensor, and finally, whether the covering member 200 is covered in place may be conveniently determined by whether the micro switch, the distance sensor, or the pressure sensor is triggered, and thus, whether the surface profile of the coil 600 is correct may be determined.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a coil measuring device according to an embodiment of the present disclosure. Alternatively, the measuring structure 300 may be disposed on the cover member 200. The measuring structure 300 includes at least one of a micro switch, a distance sensor, and a pressure sensor, which are movably engaged with the supporting member 100. Furthermore, when the covering member 200 covers the supporting member 100, the supporting member 100 may trigger the micro switch, the distance sensor, or the pressure sensor, and finally, whether the covering member 200 covers in place may be conveniently determined by whether the micro switch, the distance sensor, or the pressure sensor is triggered, and thus, whether the surface profile of the coil 600 is correct may be determined.

The number of the measurement structures 300 may be one or more, and is not limited in the embodiment of the present application.

When the number of the measurement structures 300 is plural, the plural measurement structures 300 may be respectively disposed at different positions of the supporting member 100, and the probability that the single measurement structure 300 is detected erroneously when the covering member 200 is partially tilted with respect to the supporting member 100 may be reduced.

For example, the supporting member 100 may be a square structure as a whole, and may be a measuring structure 300 disposed at each of four corners of the supporting member 100, and a first triggering portion is disposed on the corresponding covering member 200, and the first triggering portion is configured to trigger a micro switch, a distance sensor, or a pressure sensor as the measuring structure 300 when the covering member 200 covers the supporting member 100.

When the number of the measuring structures 300 is plural, the plurality of measuring structures 300 may be respectively disposed at different positions of the covering member 200, and the probability that the single measuring structure 300 is detected erroneously when the covering member 200 is partially tilted with respect to the supporting member 100 may be reduced.

For example, the entire covering member 200 may be a square structure, and one measurement structure 300 may be disposed at each of four corners of the covering member 200, and a second trigger portion is disposed on the corresponding supporting member 100, and the second trigger portion is configured to trigger a micro switch, a distance sensor, or a pressure sensor serving as the measurement structure 300 when the covering member 200 covers the supporting member 100.

In some embodiments, the support member 100 may also be provided with guide structures such as guide posts 13, guide sleeves, etc. that cooperate with the closure member 200 to improve the accuracy of the movement of the closure member 200.

For example, the supporting member 100 may be provided with a plurality of guide posts 13. The covering member 200 is provided with a plurality of guiding through holes 23, and each guiding through hole 23 is in guiding fit with one guiding post 13, so that when the covering member is covered on the supporting member 100, the guiding post 13 can be inserted into the corresponding guiding through hole 23.

At this time, the measuring structure 300 may further include a mark provided to the guide pillar 13. Further, the position of the guide post 13 inserted into the guide through hole 23 can be determined by the mark on the guide post 13, the relative position between the receiving member 100 and the covering member 200 can be determined, and finally whether or not the surface contour shape of the coil 600 is correct can be determined.

The mark may be a coating layer with a color different from that of the guide post 13, or may be a scale, a number mark, or the like formed on the guide post 13, which is not limited in the embodiment of the present application.

Taking the mark as an example of the scale formed on the guide post 13, when the covering member 200 is covered on the supporting member 100, a part of the scale may be located at a portion of the guide post 13 that is not inserted into the guide through hole 23, and a part of the scale may be located at a portion of the guide post 13 that is inserted into the guide through hole 23, and further, the relative position between the supporting member 100 and the covering member 200 may be determined by observing the scale located at the lower side opening of the guide through hole 23.

Alternatively, when the covering member 200 is covered on the supporting member 100, a part of the scale may be located at a portion where the guide post 13 passes through the guide through hole 23, and a part of the scale may be located at a portion where the guide post 13 is inserted into the guide through hole 23, and then, the relative positions of the supporting member 100 and the covering member 200 may be determined by observing the scale located at the aperture end surface of the guide through hole 23.

In some embodiments, the support member 100 may include a first mount 14 and a support 15. The supporting portion 15 is protruded from the first mounting seat 14 toward the side of the covering member 200. The first curved surface 11 is located on a side of the supporting portion 15 facing the covering member 200. It will be appreciated that the whole of the support 15 protrudes with respect to the first mounting seat 14, which may make it easier for an operator or an automated device to take and place the coil 600 towards the first curved surface 11.

In addition, in combination with the above-mentioned measuring structure 300, the mark is disposed on the guide post 13, and the guide posts 13 may be disposed at four corners of the first mounting seat 14. Further, when the covering member 200 is covered on the receiving member 100, a space can be formed between the first mounting seat 14 and the covering member 200 to expose the mark on the guide post 13.

In some embodiments, the closure member 200 includes a second mount 24 and a closure portion 25. The covering portion 25 is protruded from a side of the second mounting seat 24 facing the supporting member 100, and the second curved surface 21 is located on a side of the covering portion 25 facing the supporting portion 15.

In addition, the measuring structure 300 includes a mark disposed on the guide post 13, and the four corners of the second mounting seat 24 may be provided with guiding through holes 23, and the guiding through holes 23 are in clearance fit with the guide post 13. When the covering member 200 is covered on the receiving member 100, a space can be formed between the second mounting seat 24 and the receiving member 100 to expose the mark on the guide post 13.

In some embodiments, the first curved surface 11 may be a convex curved surface, while the second curved surface 21 is a concave curved surface. Optionally, the first curved surface 11 may be a concave curved surface, and the second curved surface 21 may be a convex curved surface, which is not limited in this embodiment.

In some embodiments, the cover member 200 may be a Polyetheretherketone (PEEK) material. It can be understood that the polyetheretherketone material has the advantages of light weight, high strength, good self-lubricating property and the like. Further, due to the advantage of light weight, false detection of the coil 600 with an unqualified partial surface contour shape caused by overweight of the covering component 200 can be reduced after the coil is pressed and deformed. Meanwhile, the bearing component 100 has the guide post 13, and the cover component 200 can slide on the guide post 13 more smoothly due to the advantages of high strength, good self-lubricating property and the like of the polyetheretherketone material.

In order to improve the positional accuracy when the coil 600 is placed on the holding member 100, the coil measuring apparatus further includes a positioning post 500. The positioning column 500 is installed on the supporting member 100, and at least a portion of the positioning column 500 protrudes from the first curved surface 11, so as to position the coil 600 supported by the first curved surface 11.

Specifically, the positioning column 500 may be inserted into the inner ring of the coil 600 to position the coil 600. It can be understood that, after the coil 600 is wound, the shape of the coil 600 is expanded, the dimensional tolerance of the shape of the coil 600 product is large, and the coil 600 product cannot be used as a positioning reference, and after the coil 600 is wound, the dimensional accuracy of the inner ring of the coil 600 is high, so that the inner ring of the coil 600 is matched with the positioning column 500 to be used as the positioning reference, and the positioning accuracy of the coil 600 can be improved. At this time, the magnetic shielding sheet 61 may be attached to the fourth curved surface of the coil 600, and the top end surface of the positioning column 500 may abut against the magnetic shielding sheet 61; if the magnetic shielding sheet 61 is not attached to the fourth curved surface of the coil 600, the covering member 200 may be provided with a clearance hole for engaging with the positioning post 500.

In some embodiments, the locating posts 500 are removably attached to the support member 100. Furthermore, when the type or size of the coil 600 is changed, the appropriate positioning posts 500 may be replaced to fit the coil 600.

Illustratively, the support member 100 is further provided with a first through hole 16, and one side of the first through hole 16 is opened at the first curved surface 11, or it can be understood that the first through hole 16 penetrates the support member 100 from the first curved surface 11 of the support member 100. At this time, the positioning column 500 is inserted into the first through hole 16 and can slide in a direction away from the support member 100 to exit from the first through hole 16, so that the positioning column 500 and the support member 100 are separated from each other, or it can be understood that the positioning column 500 can be drawn out from the bottom of the support member 100.
