Description

Technical Field

[0001] This utility model relates to the technical field of steel bar testing equipment, and in particular to a tooling for rapid inspection of the straightness of steel bars. Background Technology

[0002] A rapid straightness inspection fixture for steel bars is a device used to check whether steel bars (or other metal materials) meet straightness requirements during production and processing. Straightness refers to the deviation of the surface or edge of a steel bar from an ideal straight line. During manufacturing, the straightness of steel bars is crucial for subsequent processing, performance, and quality control. To ensure the quality of steel bars, their straightness must be inspected efficiently and accurately.

[0003] In practice, existing traditional methods for testing the straightness of steel bars mostly rely on manual measurement, such as using rulers, measuring instruments, etc., to directly measure the surface of the steel bars. This method has problems such as low measurement accuracy, high labor intensity, and slow speed. Although there are some optical or mechanical straightness testing devices on the market, these devices are often complex, expensive, and not flexible enough, especially when testing steel bars of different specifications and lengths. This leads to the need to frequently change testing devices, increasing the overall testing, use, and installation costs. At the same time, too much electrical equipment will also increase the learning cost for personnel, bringing many inconveniences.

[0004] Therefore, this utility model provides a tooling for rapid inspection of the straightness of steel bars. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a tooling for rapid inspection of the straightness of steel bars.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick inspection fixture for the straightness of steel bars, comprising two supporting base plates.

[0007] A processing platform is installed above each of the two supporting base plates. A connecting plate is installed on the top of the processing platform. A rapid inspection mechanism is installed on the top of the connecting plate. The rapid inspection mechanism includes a limiting guide rail. The limiting guide rail is fixedly connected to the top of the connecting plate. A steel bar installation chamber is slidably connected to one side of the limiting guide rail. A partition is fixedly connected inside the steel bar installation chamber. A limiting rod is fixedly connected to the bottom of the partition. A steel bar extending to the outside of the bottom of the steel bar installation chamber is installed on one side of the limiting rod. A third positioning bolt for limiting the steel bar is installed on one side of the steel bar installation chamber. The steel bar is inserted into the bottom of the steel bar installation chamber and the bottom of the partition. At this time, the steel bar is located on one side of the limiting rod. The third positioning bolt is manually tightened until the steel bar is limited, which facilitates the installation of the steel bar and the steel bar installation chamber.

[0008] A support plate is fixedly connected to the top of the connecting plate and to one side of the limiting guide rail. A support plate and a laser detection equipment mounting frame are fixedly connected to the top of the support plate. A reciprocating screw is rotatably connected between the support plate and the laser detection equipment mounting frame. A second limiting slider is threaded to the outer side of the reciprocating screw. A mounting base is fixedly connected to the top of the second limiting slider. A photoelectric sensor is fixedly connected to the top of the mounting base. A second mounting cavity is opened at the top of the laser detection equipment mounting frame. A laser displacement sensor is installed inside the second mounting cavity. The laser displacement sensor is installed through the second mounting cavity in conjunction with the laser displacement sensor. The laser displacement sensor can measure the position change of the steel bar surface very accurately and detect the straightness deviation of the steel bar in real time, thereby performing a primary inspection of the steel bar. The photoelectric sensor is used to collect the position data of the steel bar surface. Image recognition technology can identify the surface shape of the steel bar by comparing images and accurately determine whether there is irregular deformation, thereby performing a secondary inspection of the steel bar. By installing multiple sensors, the deviation of the steel bar surface from the ideal straight line can be measured quickly and accurately.

[0009] Two limiting seats are installed on the top of the processing platform and on one side of the connecting plate. Each limiting seat has two limiting sleeves on its top. The interior of each limiting seat has equidistantly distributed first mounting cavities. The top of each limiting sleeve is threaded with a second positioning bolt extending into the corresponding first mounting cavity. The top of each limiting sleeve and both sides of the second positioning bolt are threaded with first positioning bolts extending into the limiting seat. A thicker steel bar is placed with one end inside the first mounting cavity and the other end between the laser detection equipment mounting frame and the photoelectric sensor. The limiting sleeves are aligned with the surface of the limiting seats for installation. The two first positioning bolts position the limiting sleeves and the limiting seats, and the second positioning bolts position the steel bar and the limiting seats, facilitating subsequent detection of the steel bar placed between the laser detection equipment mounting frame and the photoelectric sensor.

[0010] In a preferred embodiment, reinforcing rods are fixedly connected between the two supporting base plates, supporting columns are fixedly connected to the top of the two supporting base plates, supporting platforms are fixedly connected to the top of the two supporting columns, and the tops of the two supporting platforms are fixedly connected to the processing platform. Two fixing rods are fixedly connected to the top of the processing platform on the side of the connecting plate away from the limiting seat. A handle is fixedly connected to one end of each of the two fixing rods. The fixing rods and handles facilitate manual handling of the equipment, improving its convenience. A second reinforcing side plate is installed on one side of each supporting column, and one side of each second reinforcing side plate is connected to the corresponding supporting base plate, reinforcing the connection between the supporting base plate and the supporting column. A first reinforcing side plate is installed on the outer side of each supporting platform, and one side of each first reinforcing side plate is connected to the corresponding supporting column, reinforcing the connection between the supporting platform and the supporting column, thereby improving the stability of the equipment support.

[0011] In a preferred embodiment, a lighting lamp is fixedly connected to one side of the steel bar installation chamber. A storage battery is installed inside the limiting guide rail and at the top of the partition. The storage battery provides power for some of the electrical equipment, and the lighting lamp provides on-site illumination for convenient nighttime operation. An electric telescopic rod is fixedly connected to the top of the limiting guide rail, and a first limiting slider is slidably connected inside the limiting guide rail. One side of the first limiting slider is fixedly connected to the limiting guide rail, and the output end of the electric telescopic rod is fixedly connected to the top of the first limiting slider. By operating the electric telescopic rod, the first limiting slider slides inside the limiting guide rail, thereby adjusting the height of the outer limiting guide rail as needed until the steel bar is in a convenient inspection position. This meets the inspection requirements of steel bars of different specifications and improves the overall flexibility of the equipment during use.

[0012] In a preferred embodiment, mounting rods extending into the processing platform are fixedly connected to all four sides of the bottom of the connecting plate. A drive motor is fixedly connected to one side of the laser detection equipment mounting frame. The output end of the drive motor passes through the laser detection equipment mounting frame and is fixedly connected to one end of the reciprocating lead screw. By driving the drive motor to rotate, the reciprocating lead screw is driven to rotate, which in turn drives the second limit slider on the outside to adjust its lateral position until the photoelectric sensor at the top moves to the required detection position, thereby detecting and processing the steel bar on one side.

[0013] In one preferred embodiment, a control panel is fixedly connected to the outside of one of the supporting columns. The electric telescopic pole, battery, lighting, drive motor and photoelectric sensor are all electrically connected to the control panel. The control panel is used to control the operation of the electric telescopic pole, battery, lighting, drive motor and photoelectric sensor, realizing unified management of power equipment.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a support base plate, processing platform, limit seat, and limit guide rail, the steel bar is inserted into the bottom of the steel bar installation chamber and the bottom of the partition. At this time, the steel bar is located on one side of the limit rod. The third positioning bolt is manually tightened until the steel bar is limited, facilitating the installation of the steel bar and the steel bar installation chamber. A laser displacement sensor is installed inside the second installation cavity. The installation is carried out through the second installation cavity in conjunction with the laser displacement sensor. The laser displacement sensor can measure the positional changes of the steel bar surface very accurately, and can detect the straightness deviation of the steel bar in real time, thereby performing a primary inspection of the steel bar. A photoelectric sensor is used to collect the positional data of the steel bar surface. Image recognition technology can identify the surface morphology of the steel bar by comparing images, accurately determine whether there is irregular deformation, and thus perform a secondary inspection of the steel bar. In this test, multiple sensors are installed to quickly and accurately measure the deviation of the steel bar surface from the ideal straight line. The limiting sleeve is aligned with the limiting seat surface and installed. The limiting sleeve and limiting seat are positioned and installed using two first positioning bolts, and the steel bar and limiting seat are positioned and installed using a second positioning bolt. This facilitates subsequent detection of the steel bar placed between the laser detection equipment mounting frame and the photoelectric sensor. The operation of the electric telescopic rod drives the first limiting slider to slide inside the limiting guide rail, thereby realizing the height adjustment of the outer limiting guide rail until the steel bar is in a convenient detection position. This meets the detection needs of steel bars of different specifications and improves the overall flexibility of the equipment during use. The first reinforcing side plate reinforces the connection between the support platform and the support column, thereby improving the stability of the equipment support. Attached Figure Description

[0045] Battery 45 is used to provide some of the power resources required by electrical equipment, and lighting 48 is used for on-site lighting to facilitate nighttime operations.

[0046] The operation of the electric telescopic rod 42 drives the first limit slider 49 to slide inside the limit guide rail 4, thereby realizing the height adjustment of the outer limit guide rail 4 until the steel bar 43 is in a convenient detection position, meeting the detection requirements of steel bars 43 of different specifications, and improving the overall flexibility of the equipment during use.

[0047] The drive motor 55 rotates, driving the reciprocating lead screw 56 to rotate, which in turn drives the second limit slider 57 on the outside to adjust its lateral position until the photoelectric sensor 59 at the top moves to the required detection position, thereby detecting and processing the steel bar 43 on one side.
