Abstract

The invention provides a measuring method using a coil holding device for placing a coil without tilting. The coil holding device is provided with a plurality of seating parts for seating the concentrated winding cassette coils, wherein the plurality of seating parts comprise seating parts with a first height in the vertical direction and seating parts with a second height different from the first height. The concentrated winding cassette coil has an upper surface and a lower surface, each seating part has a seating surface that contacts the lower surface and seats the concentrated winding cassette coil, and the seating surface of the seating part is located below in the vertical direction with respect to a contact point of the upper surface that contacts a probe that measures the thickness of the concentrated winding cassette coil in the vertical direction.

Description

Method for measuring holding device using coil Technical Field The present disclosure relates to a measurement method using a holding device of a coil. Background Japanese patent application laid-open No. 2013-017266 discloses a jig for supporting a coil in a process of manufacturing a concentrated winding cassette coil. The concentrated winding cassette coil is formed in a spiral shape, and thus is inclined in the stacking direction. For example, when the thickness of the coil in the lamination direction is to be inspected, the thickness is difficult to accurately measure because of the inclination. In the concentrated winding cassette coil, it is required to place the coil without tilting. Disclosure of Invention The present disclosure has been made to solve the above-described problems, and an object thereof is to provide a coil holding device capable of placing a coil without tilting. The coil holding device according to one aspect of the present disclosure is a coil holding device for holding a concentrated winding cassette stacked in a plurality of layers, wherein the coil holding device includes a plurality of seating portions for seating the concentrated winding cassette, and the plurality of seating portions include a first seating portion having a first height in a vertical direction and a second seating portion having a second height different from the first height. In the coil holding device, the concentrated winding cassette coil may have an upper surface and a lower surface, each seating portion may have a seating surface that contacts the lower surface and seats the concentrated winding cassette coil, and a contact point of the first seating surface of the first seating portion with respect to the upper surface that is contacted by a probe that measures the thickness of the concentrated winding cassette coil in the vertical direction may be located below the vertical direction. The coil holding device may further include an adjustment mechanism that moves the seating portion in a vertical direction and adjusts a height in the vertical direction. According to the present disclosure, a coil holding device capable of placing a coil without tilting can be provided. The foregoing and other objects, features and advantages of the present disclosure will be more fully understood from the detailed description given below and the accompanying drawings which are given by way of illustration only, and thus are not to be taken as limiting the present disclosure.
