Embodiment 1
[0018] Such as figure 1 , 2 Shown in and 3, a kind of silicon steel sheet laser thickness measuring device, it comprises the support 1 that is made of upper and lower two layers, and support 1 is also provided with support front plate and support rear plate. figure 2 Middle: The left side of the picture is the left end of bracket 1, and the right side of the picture is the right end of bracket 1; the front side of bracket 1 is close to the reader, and the rear end of bracket 1 is the opposite; the top side of the picture is the upper end of bracket 1, and the bottom side of the picture is bracket 1 the lower end. The support 1 is composed of a support top plate, a support front plate, a support rear plate, a support side plate and a support bottom plate to form a frame structure. A horizontal bracket partition is arranged in the middle of the bracket 1, and the middle of the bracket partition is disconnected. The bracket partition divides the bracket 1 into four cavities: u...

The invention provides a silicon steel sheet laser thickness measuring device, which relates to the technical field of measurement. It includes a bracket consisting of upper and lower layers. Upper side panels are fixed at the left and right ends of the upper layer of the bracket, and lower side panels are fixed at the left and right ends of the lower layer of the bracket. The distance between the two upper side panels is smaller than that between the two lower side panels. The distance between the two lower side plates is rotatably connected with a support shaft, and a pair of rotatable pressure rollers are arranged above the support shaft, and a laser transmitter and a CCD receiver are arranged above the distance between the two pressure rollers. The axis of the wheel is parallel to the axis of the support shaft, and the pressure wheel is connected to the upper layer of the bracket through the set pressure roller assembly to move up and down, and the pressure wheel is in crimping contact with the support shaft. The beneficial effect of the invention is that: the supporting shaft of the thickness measuring device and the pressing wheel press the silicon steel sheet to be measured at three points collinearly to ensure the measurement accuracy. Only one pair of laser transmitter and CCD receiver is needed, saving cost. The structure is small and compact, easy to carry, and has a wide range of applications.
Description
technical field [0001] The invention relates to the technical field of measurement, in particular to a device for measuring the thickness of a silicon steel sheet. Background technique [0002] Silicon steel sheet is an iron-silicon alloy with a silicon content of 0.5% to 4.8%. It is a soft magnetic material widely used in the electrical field, mainly used in motors, generators, transformers, electromagnetic mechanisms, relay electronic devices and measuring instruments. Electrical silicon steel sheets are usually rolled into large sheets or strips of standard size for use. The thickness uniformity of silicon steel sheets is a very important quality characteristic. If the thickness difference between the center and the edge of the silicon steel sheet is too large, or the thickness variation in the length direction of the silicon steel sheet is too large, it will affect the thickness of the assembled iron core. With different core thicknesses, the magnetic permeability cha...
