Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel measuring devices, in particular to a threaded steel laser measuring system. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars, which are essential materials in the construction industry. Therefore, their performance must be qualified before they can be put into use. With the progress of society and the development of the economy, the application of rebar is becoming more and more extensive. Different fields have different requirements for rebar. Therefore, in the process of rebar forming, in order to standardize the production of rebar, it is necessary to measure different aspects of rebar.

[0003] Existing Chinese patent document CN202321591409.6 describes a device for measuring the spacing between transverse ribs of threaded steel. The device comprises a bracket, one end of which is provided with a stopper for blocking the threaded steel, and the other end of the bracket is fixedly connected to a circular hole plate. The stopper and the circular hole plate are positioned in a corresponding manner. The circular hole plate is used to pass through a push rod, which is sleeved with a spring. The end of the push rod is fixedly connected to a spring stopper washer, which is used to prevent the spring from escaping from the push rod. The spring stopper washer and the stopper are used to clamp the threaded steel. By pulling the push rod, the spring stopper is used to clamp the threaded steel to the stopper, preventing the threaded steel from rotating and moving laterally. This facilitates the measurement of the spacing between the transverse ribs of the threaded steel, is convenient and fast, and improves the accuracy of the measurement data.

[0004] However, the above patent has certain defects when used. The device uses a clamping device to position and clamp the threaded steel to prevent the threaded steel from rotating and moving laterally, and then uses a vernier caliper to measure it. It is convenient and fast, but manual measurement with a vernier caliper is not accurate enough, resulting in large errors.

[0005] Therefore, a threaded steel laser measurement system is proposed to solve the above problems. Utility Model Content

A measuring window for the laser measuring instrument 4 is provided on the top of the measuring box 3 to ensure that the laser can accurately irradiate the threaded steel. The laser measuring instrument 4 is used to detect the threaded steel on the measuring platform 1. The laser measuring instrument 4 has the characteristics of high precision and fast response, and can measure the diameter, length and other dimensions of the threaded steel in real time. A controller 6 is provided on the front of the measuring box 3 for controlling the working state and data recording of the laser measuring instrument 4.

[0031] The side of the laser measuring instrument 4 is provided with an illuminating lamp 5, which is fixed to the top of the measuring box 3 and is used to provide lighting during the measurement process to ensure measurement accuracy. The interior of the measuring box 3 is provided with a mounting plate 8, which is fixed to the inner wall of the measuring box 3;

[0032] Two sets of camera devices are provided at the lower end of the mounting plate 8, and the camera devices include a connecting rod 81 and a camera 83. A fixing plate 82 is provided on the upper surface of the camera 83, and a rotating shaft 84 is provided on the side wall of the fixing plate 82. The rotating shaft 84 passes through the lower end of the connecting plate to fix the camera 83 to the connecting rod 81 to achieve angle adjustment of the camera 83. A thread is provided at the front end of the rotating shaft 84, and a nut 85 is provided on the rotating shaft 84 for locking the angle of the camera 83 to prevent the camera 83 from shaking during the measurement process.

[0033] The measuring platform 1 is provided with a mounting opening 14 at its center. A conveyor 7 is provided within the mounting opening 14 for automatically feeding the rebar into the measuring box 3 for measurement.
