Description

Technical Field

[0001] The utility model relates to the field of steel processing, in particular to a handheld rod material type measuring tool. Background Art

[0002] In bar production, material shape measurement is the most basic operation. At present, when performing dimensional measurement in China, the measurement method of calipers and steel rulers is often relied on. After clamping the bar with the calipers, the degree of the calipers is measured with a steel ruler.

[0003] Although the above measurement method can complete the measurement work, the accuracy depends on the measurement experience of the rolling worker, the error fluctuates greatly, and the temperature is high and the speed is fast during the rolling process, which is prone to danger. Utility Model Content

[0004] The purpose of this utility model is to provide a handheld bar material measuring tool to solve the existing method of measuring bars using calipers and steel rulers. Its accuracy depends on the measurement experience of the rolling workers, the error fluctuation is large, and the temperature is high and the speed is fast during the rolling process, which is prone to danger.

[0005] To achieve the above-mentioned objectives, the present utility model provides a handheld rod material type measuring tool, comprising a measuring frame, which includes two sets of measuring plates, one end of which is fixedly connected by a connecting plate, wherein the two sets of measuring plates are arranged in parallel, and a set of measuring sliders are respectively installed near the end, and a set of laser rangefinders are correspondingly provided on the near end surfaces of the two sets of measuring sliders, a switch for activating the two sets of laser rangefinders to continue measuring distance is provided on the connecting plate, and a display screen for displaying the distance measurement information of the laser rangefinder is provided on the connecting plate.

[0006] As a further solution of the present invention, a handle for people to hold is provided on the connecting plate.

[0007] As a further solution of the present invention, a support plate for supporting personnel is provided at the bottom of the measuring plate.

[0008] Compared with the existing technology, the utility model uses two sets of laser rangefinders on both sides of the measuring frame to clamp and measure the size of the bar, thereby replacing the manual method of measuring the bar using calipers and steel rulers. It solves the existing method of measuring the bar using calipers and steel rulers, whose accuracy depends on the measurement experience of the rolling workers, has large error fluctuations, and is prone to danger due to high temperatures and high speeds during the rolling process.

[0011] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.

[0012] like Figure 1 As shown, in an embodiment of the present utility model, a handheld rod material type measuring tool includes a measuring frame 1, which includes two sets of measuring plates, one end of the two sets of measuring plates is fixedly connected by a connecting plate, wherein the two sets of measuring plates are arranged in parallel, and a set of measuring sliders 2 are respectively installed near the end, and a set of laser rangefinders 3 are correspondingly provided on the near end surface of the two sets of measuring sliders 2. The connecting plate is provided with a switch 6 for starting the two sets of laser rangefinders 3 to continue measuring distance, and the connecting plate is provided with a display screen 4 for displaying the distance measurement information of the laser rangefinder 3;

[0013] When the utility model is in use, the two sets of laser rangefinders 3 on both sides of the measuring frame 1 clamp and measure the size of the bar 8, wherein the distance between the two sets of measuring plates on the measuring frame 1 is a fixed length. When reading the size of the bar 8, the distance data read by the two sets of laser rangefinders 3 are a and b respectively. At this time, the size s3 of the bar 8 = Lab;

[0014] In addition, the present invention places the laser rangefinder 3 on two sets of measuring slides 2. When measuring a bar 8 that is too deep, the measuring slides 2 can be moved to adjust the position of the distance sensor, and the positions of the upper and lower laser rangefinders 3 can be calibrated to ensure that the laser rangefinders 3 are on the same longitudinal axis.

[0015] like Figure 1 As shown, in the embodiment of the present utility model, a handle 5 for personnel to hold is provided on the connecting plate, which is convenient for personnel to hold the measuring frame 1, and a support plate 7 for personnel to support is provided at the bottom of the measuring plate, which further improves the stability of personnel when using the measuring frame 1 for measurement.

[0016] In summary, the present invention uses a measuring frame 1 and two sets of laser rangefinders 3 on both sides of the measuring frame 1 to clamp and measure the size of the bar 8, thereby replacing the manual method of using calipers and steel rulers to measure the bar 8. This solves the existing method of using calipers and steel rulers to measure the bar 8, the accuracy of which depends on the measurement experience of the steel rolling workers, the error fluctuation is large, and the temperature is high and the speed is fast during the rolling process, and it is easy to be dangerous.

[0017] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
