Abstract
Description
Technical Field
[0001] The utility model relates to a device for measuring the width of a formed plate of a hot test rolling mill, belonging to the technical field of the production of hot test rolling mills in the metallurgical industry. Background Art
[0002] The 550 hot test rolling mill is a pilot hot rolling mill, which mainly uses a relatively low cost to roll billets into plates and explore rolling processes. After rolling is completed, the formed plates need to be conveyed to a cooling bed by a conveying roller table for cooling. After the test process is completed, it is necessary to measure the actual width of the rolled formed plates to facilitate the adjustment of the rolling process.
[0003] Since the final rolling temperature of the formed plates is above 800°C, their width cannot be measured manually. Generally, ray measurement is used for measurement. However, ray measurement requires multiple cameras and complex calculation programs to calculate the width of the plates. Although online precise measurement can be achieved, the structure is complex and the cost is relatively high, which is not very suitable for pilot test rolling mills. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a device for measuring the width of a formed plate of a hot test rolling mill, which converts the width of the formed plate into the distance between two clamping blocks, and then uses a laser for distance measurement to solve the problems existing in the background art.

[0006] A device for measuring the width of a formed plate of a hot test rolling mill includes a motor, a first base, a light shaft, a lead screw, a first clamping block, a second clamping block, a laser head and a second base. The light shaft and the lead screw are arranged in parallel on the same horizontal plane. The two ends of the light shaft are respectively fixed on the first base and the second base, and the two ends of the lead screw are respectively rotatably connected to the first base and the second base. The motor is drivingly connected to the lead screw; the first clamping block and the second clamping block are respectively connected to the light shaft and the lead screw, and a laser head for measuring the distance between the first clamping block and the second clamping block is provided on the first clamping block or the second clamping block.
[0007] Both the first clamping block and the second clamping block are provided with a light sleeve matching with the light shaft and a thread sleeve matching with the lead screw.
[0008] The thread directions of the thread sleeves on the first clamping block and the second clamping block that match the lead screw are opposite.
[0009] The opposite surfaces of the first clamping block and the second clamping block are clamping surfaces matching with the formed plate.
[0010] The opposite surfaces of the first clamping block and the second clamping block are triangular.
[0011] The two ends of the lead screw are respectively rotatably connected to the first base and the second base through a first copper sleeve and a second copper sleeve.
[0012] The beneficial effects of the present utility model are as follows: Through the transmission of the lead screw, the width of the formed plate is converted into the distance between the first clamping block and the second clamping block, and then laser ranging is adopted to achieve the purpose of measuring the width of the high-temperature plate at low cost.
