Description

Technical Field

[0001] This utility model relates to the field of laser measurement technology, specifically a laser measuring instrument for steel pipe thickness. Background Technology

[0002] For precision manufacturing of steel pipe workpieces with processing requirements, after the initial shaping process, in order to ensure that the output steel pipes meet the dimensional and precision requirements, it is necessary to measure the thickness of the steel pipes. Existing methods, such as laser measurement and physical fixture measurement, use optical or direct physical measurement methods to intuitively judge the quality of the steel pipe output, preventing dimensional differences from affecting subsequent secondary processing or assembly applications. A search revealed that Chinese Patent Publication No. CN119022808A discloses an automatic clamping laser measuring instrument for steel pipe thickness, including: a rotating frame, the lower end of which is hinged to a table; and a liquid chamber fixed to the bottom of the support base. The bottom of the liquid chamber is connected to the interior of a sealed elastic telescopic rod through a gas guide pipe. A hydraulic push plate is also installed in a sealed, movable manner inside the upper half of the liquid chamber. A pneumatic movement control component for driving the lifting and lowering of the hydraulic push plate is provided at the bottom of the liquid chamber.

[0003] Although the above technical solution can utilize the weight of the steel pipe to be tested to achieve adhesive positioning of the steel pipe and facilitate thickness measurement, and make it convenient for subsequent removal and placement of the steel pipe, the steel pipe is placed on the support during use. Therefore, only a single position of the steel plate can be measured. When measuring other positions, the steel pipe needs to be rotated and moved, which increases the workload. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a laser measuring instrument for steel pipe thickness, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel pipe thickness laser measuring instrument, including a handle, one end of which is fixedly connected to a first motor, the output of the first motor is fixedly connected to a turntable, an adjustable positioning mechanism is installed inside the turntable, and a laser measuring mechanism is installed on the outer surface of the turntable;

[0006] The adjustable positioning mechanism includes two symmetrically formed grooves on the outer surface of the turntable. A crossbar is slidably connected inside each of the two grooves. Two sliders are symmetrically slidably connected to one side of the outer surface of the crossbar. A connecting rod is fixedly connected to one side of the slider, and a positioning plate is fixedly connected to one end of the connecting rod.

[0007] Preferably, a second motor is embedded and fixedly installed inside the slide groove, and the output shaft of the second motor is fixedly connected to a bidirectional lead screw. Both crossbars are threadedly connected to the bidirectional lead screw, which facilitates driving the two crossbars to move relative to each other.

[0008] Preferably, a dual-axis motor is fixedly installed at the center of one side of the outer surface of the crossbar, and one-way lead screws are fixedly connected to both ends of the dual-axis motor. The slider is threadedly connected to the corresponding one-way lead screw, which facilitates driving the two sliders to move relative to each other.

[0009] Preferably, the positioning plate has multiple contact balls embedded inside for easy contact with the surface of the steel pipe, facilitating positioning and rotation.

[0010] Preferably, the laser measuring mechanism includes a first support rod fixedly connected to the center of the turntable, a first laser sensor fixedly connected to one end of the first support rod, and a second support rod fixedly connected to one edge of the outer surface of the turntable, a second laser sensor cooperating with the first laser sensor fixedly connected to one end of the second support rod, which facilitates the measurement and calculation of the thickness of the steel pipe.

[0011] Preferably, a control panel is fixedly connected to the outer surface of the handle to facilitate the overall control and operation of the measuring instrument.

[0012] This utility model provides a laser measuring instrument for steel pipe thickness. It has the following beneficial effects:

[0013] This laser thickness measuring instrument for steel pipes, through its adjustable positioning mechanism and laser measuring mechanism, can clamp and position steel pipes of different diameters during use. It then drives the first and second laser sensors to rotate, enabling it to measure not only the circumferential thickness of the steel pipe but also measurements at different positions. This improves practicality and solves the problem of existing devices being unable to measure the circumferential rotation of the steel pipe, requiring repeated adjustments to the pipe's direction of rotation, which is inconvenient.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] like Figures 1 to 3 As shown, a laser measuring instrument for steel pipe thickness includes a handle 1. A first motor 2 is fixedly connected to one end of the handle 1. The output of the first motor 2 is fixedly connected to a turntable 3. An adjustable positioning mechanism 4 is installed inside the turntable 3. The adjustable positioning mechanism 4 includes two symmetrically formed grooves 41 on the outer surface of the turntable 3. A crossbar 42 is slidably connected inside each groove 41. Two sliders 43 are symmetrically slidably connected to one side of the outer surface of the crossbar 42. A connecting rod 44 is fixedly connected to one side of each slider 43. A positioning plate 45 is fixedly connected to one end of the connecting rod 44. A second motor is embedded and fixedly installed inside the grooves 41. A bidirectional lead screw 47 is fixedly connected to the output shaft of the second motor. Both crossbars 42 are threadedly connected to the bidirectional lead screw 47. A dual-axis motor 48 is fixedly installed at the center of one side of the outer surface of the crossbar 42. A unidirectional lead screw 49 is fixedly connected to both ends of the dual-axis motor 48. The sliders 43 are threadedly connected to the corresponding unidirectional lead screw 49. Multiple contact balls 46 are rotatably connected inside the positioning plate 45.

[0021] In use, starting the second motor and the dual-axis motor 48 can drive the bidirectional lead screw 47 and the unidirectional lead screw 49 to rotate respectively, which in turn can drive the four positioning plates 45 to move relative to each other, so that the contact ball 46 contacts the surface of the steel pipe. Then, the rotation of the first motor 2 can drive the turntable 3 to rotate, which can make the laser measuring mechanism 5 rotate circumferentially along the steel pipe.

[0022] Example 2:

[0023] like Figures 1 to 3As shown, a laser measuring mechanism 5 is mounted on the outer surface of the turntable 3. The laser measuring mechanism 5 includes a first support rod 51 fixedly connected to the center of the turntable 3, a first laser sensor 52 fixedly connected to one end of the first support rod 51, and a second support rod 53 fixedly connected to one edge of the outer surface of the turntable 3. A second laser sensor 54, which cooperates with the first laser sensor 52, is fixedly connected to one end of the second support rod 53. A control panel 6 is fixedly connected to the outer surface of the handle 1.

[0024] The first laser sensor 52 can measure the distance between the inner walls of the steel pipe, and the second laser sensor 54 can measure the distance between the outer walls of the steel pipe. The thickness of the steel pipe can be obtained by subtracting the two distances mentioned above from the distance between the first laser sensor 52 and the second laser sensor 54.

[0025] Working principle: When in use, starting the second motor and the dual-axis motor 48 can drive the bidirectional lead screw 47 and the unidirectional lead screw 49 to rotate, which in turn can drive the four positioning plates 45 to move relative to each other, so that the contact ball 46 contacts the surface of the steel pipe. Then, the rotation of the first motor 2 can drive the turntable 3 to rotate, which can make the laser measuring mechanism 5 rotate circumferentially along the steel pipe. The first laser sensor 52 can measure the distance between the inner walls of the steel pipe, and the second laser sensor 54 can measure the distance between the outer walls of the steel pipe. The thickness of the steel pipe can be obtained by subtracting the two distances mentioned above from the distance between the first laser sensor 52 and the second laser sensor 54.
