Description

Clamping device capable of measuring size of rolled round steel at high temperature Technical Field The utility model relates to the technical field of rolled round steel size measurement, in particular to a clamping device capable of measuring the rolled round steel size at high temperature. Background The rolling of round steel bar is completed under high temperature, the dimensional accuracy of the rolled round steel is the core quality index of steel products, and whether the products can be delivered smoothly is directly influenced. Therefore, in order to control the rolling size, the rolling size condition needs to be monitored regularly, and the rolling mill is convenient to adjust correspondingly only if the size condition of the just-rolled high-temperature round steel bar is accurately known. The current common size monitoring is that the on-line calliper is used for monitoring and measuring and monitoring after taking materials. The method comprises the steps of taking materials, measuring and monitoring by using a micrometer after taking materials, wherein the micrometer is used for measuring and monitoring, although the dimensional measurement precision is high, the operation difficulty is high when the high-temperature round steel just rolled is manually measured, and the safety of measuring staff is seriously threatened. Therefore, the clamping device capable of directly measuring the size of the high-temperature round steel bar is designed, cost investment is reduced, rolling size can be monitored conveniently, and adjustment and control of the rolling line size are still necessary. Disclosure of utility model The utility model aims to provide a clamping device capable of measuring the size of rolled round steel at high temperature, so as to solve the problems that in the prior art, the on-line calliper monitoring equipment is high in investment and maintenance cost, regular calibration is needed, the diameter measurement value is difficult to find after deviation occurs, and the micrometer is used for measuring and monitoring after taking materials, although the size measurement precision is high, the operation difficulty is high when the freshly rolled round steel is measured manually. The clamping device comprises a measuring clamping plate and a handheld rod, wherein the measuring clamping plate is divided into a first clamping plate part, a second clamping plate part and a connecting part, the first clamping plate part and the second clamping plate part are arranged opposite to each other, the connecting part is used for connecting the first clamping plate part and the second clamping plate part, the first clamping plate part, the second clamping plate part and the connecting part can be matched to form a clamping space for measuring the size of rolled round steel, the handheld rod is fixedly connected to the connecting part, the installation position of the handheld rod is different from that of the clamping space, the clamping space is sequentially divided into a first clamping section, a second clamping section and a third clamping section along the depth direction of the clamping space, the first clamping section, the second clamping section and the third clamping section are connected in a smooth mode, the inner diameter of the first clamping section is kept unchanged, the inner diameter of the second clamping section is gradually reduced, and the third clamping section is kept unchanged along the depth direction of the clamping space. Based on the technical characteristics, when the clamping device designed by the utility model is used for measuring the round steel size, the center line of the round steel size cannot pass through the first clamping section when the measured round steel size is overlarge, and the round steel whole body can pass through the third clamping section when the measured round steel size is undersize until the upper part of the round steel contacts the connecting part of the measuring clamping plate. When the measured round steel is within the allowable tolerance range, the center line of the round steel size falls into the second clamping section, and when the specification size of the round steel is smaller, the center line of the round steel size is closer to the third clamping section, and when the specification size of the round steel is larger, the center line of the round steel size is closer to the first clamping section. Therefore, when the measured round steel is within the allowable tolerance range, the rolling size can be reduced or enlarged in advance according to the specific position of the center line of the round steel size in the second clamping section, specifically, when the center line of the round steel size is closer to the first clamping section, the rolling size of the round steel can be reduced adaptively, and when the center line of the round steel size is closer to the third clamping section, the rolling size of the round steel
