Scanning type plate and strip rolled metal thickness and profile measuring instrument
A profile measurement and scanning technology, applied in measurement devices, instruments, optical devices, etc., can solve the problem of inability to determine the maximum value Hmax, minimum value Hmin and average value Hpin of the thickness of the section profile, inability to obtain plates and tapes. Rolling information, not to mention meeting the needs of learning and understanding, etc.

[0032] Such as figure 1 As shown, the scanning profile measuring instrument for strip rolling thickness includes: the first measuring head 1 and the second measuring head 2 arranged above and below the strip rolling material, and the first measuring head 1 and the second measuring head 2 are corresponding , that is, the perpendicular intersection point between the two and the central axis plane of the thickness of the bar is the same point, which can ensure the accuracy of the measurement results. The sheet tie material is generally in the form of a sheet. Although it has thickness, the thickness is very small compared to the length and width. The upper and lower sides of the tie material mentioned here refer to the upper and lower sides when the tie material is placed horizontally. The relative positions of the three.
[0033] When measuring, the first measuring head 1 and the second measuring head 2 reciprocate in the same direction at the same speed, and always ensure that...

[0044] Such as Figure 5 As shown, the crank slider structure is used to drive the movement of the measuring head. The drive mechanism includes a second motor 3.2.1, a crank 3.2.2, a connecting rod 3.2.3 and a second slider 3.2.4. The two ends of the crank 3.2.2, one end is fixedly connected with the rotating shaft of the second motor 3.2.1, the other end is movably hinged with one end of the connecting rod 3.2.3, and the other end of the connecting rod 3.2.3 is connected with the second slider 3.2 .4 active connections. The measuring head is fixedly connected with the second slider 3.2.4, and the second sliding block 3.2.4 is slidably connected with the measuring head track 4. The slidable connection between the same slider and the track or slide rail is a common practice in the art and is a prior art, so it will not be repeated here.

[0046] Such as Figure 6 As shown, the ball screw structure is used to drive the movement of the measuring head. The drive mechanism includes a lead screw 3.3.4 and a screw nut 3.3.3 located in the middle of the lead screw. The screw thread of the screw nut 3.3.3 is provided with balls, and the screw nut 3.3.3 is fixedly connected to the third slide block 3.3.5. Three sliders 3.3.5 are fixedly provided with measuring heads. One end of the leading screw is connected with the rotating shaft of the third motor 3.3.1. The third sliding block 3.3.5 is slidingly connected with the slideway 3.3.2. The slideway 3.3.2 and the probe track 4 can be the same slideway. When the motor rotates, the lead screw also rotates, and the slider moves through the screw nut and the balls in it, thereby realizing the movement of the measuring head.
