Description

Technical Field

[0001] The present application relates to the technical field of measuring devices, and in particular to an online measuring device for the size of a metal bar. Background Art

[0002] The production of metal bars is a crucial step in the metalworking industry. During the production process, metal bars can develop surface defects such as curvature due to various factors, such as raw material inhomogeneity, processing fluctuations, and equipment wear. These curvature defects not only affect the appearance of the metal bar but can also cause a series of problems during subsequent processing and use, such as reduced machining accuracy, assembly difficulties, and decreased structural strength, thereby affecting the overall performance and service life of the product.

[0003] Currently, traditional methods for detecting surface bending in metal bars rely primarily on visual inspection and simple manual measurement tools. Visual inspection is inefficient and susceptible to subjective factors, making it difficult to accurately determine the degree of bending. While manual measurement tools can provide certain measurement data, they are cumbersome, slow, and difficult to achieve continuous, real-time detection, making them unsuitable for large-scale and automated production.

[0004] With the development of industrial automation technology, some devices for measuring the size of metal bars have appeared on the market. However, most of these devices focus on measuring the basic dimensional parameters of metal bars, such as diameter and length, and are relatively weak in detecting defects such as surface bending. Although some devices can detect certain bending conditions, they have problems such as low detection accuracy, poor adaptability, complex structure, and high cost, making them difficult to be widely used in actual production. For example, some measuring devices based on optical principles can achieve non-contact measurement, but when measuring metal bars with a small degree of bending, they are easily affected by factors such as light interference and reflection, resulting in inaccurate measurement results.

[0005] Therefore, this application aims to provide an online size measurement device for metal bars. Through innovative design and structural optimization, it effectively solves the problems existing in the existing technology of metal bar surface bending detection, realizes fast, accurate and online measurement of the surface bending of metal bars, and provides a reliable technical means for quality control in the metal processing industry.

[0027] Through the cooperation of the detection component and the adjustment component, the detection mechanism can not only realize the precise detection of the outer wall of the metal bar, but also has good adaptability and can be flexibly adjusted according to the metal bars of different diameters. The detection component is specially used for detecting the outer wall of the metal bar, and can accurately measure the curvature of the metal bar surface, diameter change and other dimensional parameters to ensure high precision and reliability of the detection. The adjustment component allows the operator to quickly adjust the position of the detection component according to the diameter of the metal bar, thereby ensuring that the detection component and the metal bar always maintain the best detection distance and contact state.

[0028] Preferably, the detection component includes a fixing frame, which is fixed to the top of the base plate by bolts, and a telescopic block is provided inside the fixing frame, and four telescopic blocks are provided, and the four telescopic blocks are distributed in a ring shape with equal intervals, and the telescopic block has an arc-shaped structure, a groove is provided on one side of the telescopic block, and a ball is embedded in the groove, and an arc plate is provided on the outside of the ball, and the arc plate is connected to the telescopic block by screws, and the annular plate and the ball are in sliding contact with each other, the telescopic block is sleeved on one end of the slide rod, and the outer wall of the slide rod is provided with a strip-shaped protruding structure, and the outside of the slide rod is sleeved with a first spring, and one end of the slide rod is in contact with a pressure sensor, and the pressure sensor is connected to the controller signal;

Specifically, the fixing frame is fixed to the top of the base plate by bolts, providing a stable support base for the entire detection component. The four telescopic blocks arranged in a circular shape with equal spacing inside have an arc-shaped structure that can fit tightly to the outer wall of the metal bar, ensuring the uniformity and comprehensiveness of the detection. The groove on one side of the telescopic block is embedded with a ball, which slides in contact with the arc plate.

The scale on the surface of the adjustment block and the reading arrow on the surface of the fixed frame provide the operator with intuitive position readings, making the adjustment process more accurate and convenient. This design not only improves the adaptability and flexibility of the device, but also ensures the stability and accuracy of the detection process, providing reliable technical support for the quality control of metal bars.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] (1) The metal bar size online measuring device of the present application effectively solves the problems of low efficiency, poor accuracy and difficulty in automation of traditional manual detection, as well as the problem that existing automated detection devices are easily affected by factors such as light interference and reflection, through innovative mechanical structure design and automated control technology. Specifically, the device uses a first cylinder to drive the connecting block and the lifting plate to move back and forth, thereby realizing the automatic one-by-one delivery of metal bars, avoiding the tedious operation of manual placement one by one, and improving the feeding efficiency. In the detection link, the metal bar slides in contact with the ball surface when moving. When bending occurs, the arched side of the bending pushes the telescopic block, and then the telescopic block pushes the slide rod to touch the pressure sensor. The pressure sensor feeds back the signal to the controller, thereby automatically measuring the bending condition of the metal bar surface. This detection principle based on mechanical contact and pressure sensing is not affected by light conditions, ensuring the accuracy and stability of the detection. Even in an environment with dim light or strong reflection, it can perform stable measurements, meeting the high requirements of large-scale production and automated production for metal bar quality detection.

[0034] (2) The device achieves high-precision and high-adaptability detection functions through the cooperation of the detection component and the adjustment component. The telescopic block, ball bearing, slide rod, pressure sensor and other components in the detection component can accurately measure the bending of the metal bar surface; the arc-shaped structure of the telescopic block and the rolling contact of the ball bearing ensure the smoothness of the metal bar during movement and reduce the influence of friction on the measurement results; at the same time, the pressure sensor can accurately sense the displacement change of the telescopic block, thereby accurately measuring the bending degree of the metal bar; the adjustment component realizes fine adjustment of the position of the pressure sensor through the telescopic rod, threaded rod, adjustment block and other components; by turning the knob, the threaded rod rotates, and then the adjustment block moves. The adjustment block adjusts the distance between the pressure sensor and one end of the slide rod through the telescopic rod, thereby adjusting the threshold of triggering the pressure sensor to adapt to metal bars of different diameters and bending degrees; this adjustable design enables the device to be widely used in the detection of metal bars of various specifications, improves the versatility and practicality of the device, reduces the equipment cost of the enterprise, and also ensures high-precision measurement.
