Fig. 1-3 show a device for detecting the thickness of a coating of an enameled wire, which comprises a bottom plate 100, a fixed clamping mechanism 200, a movable clamping mechanism 300, an expansion link 400 and a measuring mechanism 500. The fixed clamping mechanism is fixedly arranged at one end of the bottom plate and used for clamping one end of the enameled wire to be detected. The movable clamping mechanism and the fixed clamping mechanism are arranged at the other end of the bottom plate oppositely and used for clamping the other end of the enameled wire to be detected. The telescopic rod is fixedly connected with the fixed clamping mechanism at one end and the movable clamping mechanism at the other end so as to ensure the synchronous rotation of the fixed clamping mechanism and the movable clamping mechanism. And the measuring mechanism is arranged between the movable clamping mechanism and the fixed clamping mechanism and is used for accurately measuring the diameter of the enameled wire.
As a further improvement of the above-described facts, the fixed clamp mechanism has various forms. Preferably, the fixed clamping mechanism 200 includes a fixed base 210 fixedly installed at one end of the base plate, an arc-shaped first arc-shaped chute 211 is arranged in the fixed base, a first rotating disc 220 in sliding fit with the first arc-shaped chute is arranged in the first arc-shaped chute, a first clamping sleeve 230 coaxial with the first rotating disc is arranged at a central position of the first rotating disc, a first trapezoidal hole 231 is axially arranged in the first clamping sleeve in a through manner, and a first trapezoidal bolt 240 is inserted in the first trapezoidal hole. After one end of the enameled wire penetrates into the first trapezoidal hole, the first trapezoidal bolt is inserted into the first trapezoidal hole, so that one end of the enameled wire is fixedly clamped. Meanwhile, in order to enable the enameled wire to rotate at an accurate angle during measurement, three pin holes 221 are formed in the first turntable, and a positioning pin 250 capable of being inserted into one of the pin holes is formed in the fixing base. In addition, the specific structure of the movable clamping mechanism includes a movable base 310 slidably disposed in the base, the lower portion of the movable base is substantially T-shaped, two locking bolts 320 are symmetrically screwed on two sides of the movable base, and the ends of the locking bolts abut against the surface of the bottom plate to fix the movable base on the bottom plate. In addition, a second arc-shaped sliding groove 311 is arranged in the movable base, a second rotating disc 330 is slidably arranged in the second arc-shaped sliding groove, a second clamping sleeve 340 coaxial with the second rotating disc is arranged in the middle of the second rotating disc, a second trapezoidal hole 341 penetrating in the axial direction is arranged in the second clamping sleeve, and a second trapezoidal bolt 350 is slidably inserted in the second trapezoidal hole.
