[0001] The invention relates to the technical field of engineering detection equipment, and in particular to a steel bar marking device. Background Art

[0002] Before conducting a steel bar tensile test, it is necessary to first draw marking lines on the surface of the steel bar. The number of marking lines that need to be drawn on the same steel bar is relatively large, usually more than 30, and the intervals between the marking lines on the steel bar will vary depending on the test conditions. In the prior art, the marking of steel bars is generally performed by testers who measure the length of the steel bar and manually draw the marks, which is not only inefficient but also difficult to ensure continuous accuracy, and is prone to errors in the test results. Summary of the invention

[0003] The object of the present invention is to overcome the deficiencies of the prior art and to provide a steel bar marking device which has a novel structure and can engrave multiple marks on a steel bar at one time and can conveniently adjust the marking interval.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a steel bar marking device, comprising a base, fixed seats arranged on both sides of the base, and a plurality of adjustable components installed on the base and arranged between the fixed seats on both sides; a guide rail extending horizontally along the length direction is formed on the base, and the adjustable component comprises a movable seat that cooperates with the guide rail and slides along the guide rail and a wheel saw assembly installed on the movable seat, the movable seat is provided with a receiving groove for receiving steel bars, and a cutting groove extending into the receiving groove is opened on the movable seat, the wheel saw assembly comprises a wheel saw for installing a wheel saw bracket of the wheel saw, the wheel saw bracket is hinged to the movable seat, and the wheel saw is aligned with the cutting groove.

[0005] The beneficial effects of the present invention are as follows: the multiple adjustable components of the steel bar marking device of the present invention can be slidably adjusted along the guide rails of the base to adjust the spacing between the adjustable components, each adjustable component is equipped with a wheel saw for marking the steel bars, and the wheel saw and the adjustable component can be slidably adjusted synchronously, and finally the spacing between the marks on the steel bars can be adjusted by the adjustable components, which can be applied to a variety of different marking requirements, and has strong adjustability and a wide range of applications.

[0006] Preferably, the side of the guide rail is provided with a buckling groove with a T-shaped cross section, and each movable seat of the adjustable component is connected with a T-bolt that is buckled with the buckling groove and a locking nut that is threadedly connected to the T-bolt. The above structure can be used to quickly lock or unlock the adjustable component on the guide rail. Specifically, when the position of the adjustable component needs to be locked, the head of the T-bolt and the buckling groove are buckled with each other by tightening the locking nut, thereby increasing the friction between the large guide rail and the adjustable component and locking the adjustable component in the current position; conversely, the guide rail and the adjustable component can be unlocked by loosening the locking nut to loosen the head of the T-bolt and the buckling groove, thereby allowing the adjustable component to slide freely for adjustment.

[0007] Preferably, the wheel saws of the adjustable components are connected to a synchronous rotating shaft, and the fixed seats on both sides are installed with shaft seat assemblies, the shaft seat assemblies include a shaft seat and a shaft seat bracket hinged to the fixed seat, and the shaft seats on both sides support the synchronous rotating shaft. The synchronous rotating shaft can realize the synchronous rotation of the wheel saws on the adjustable components, so that multiple marking points on the steel bar can be marked at the same time, which improves efficiency.

[0008] Preferably, one or both ends of the synchronous rotating shaft are connected to a first hand wheel, which can be used to manually drive the synchronous rotating shaft to rotate, thereby driving each wheel saw to rotate and carve marks on the steel bar.

[0009] Preferably, one end of the synchronous shaft is connected to a reduction motor for driving the synchronous shaft to rotate. The reduction motor can drive the synchronous shaft to rotate, thereby driving each wheel saw to rotate and carve marks on the steel bar.

[0010] Preferably, the fixing seats on both sides are provided with clamping components for fixing the steel bars, the clamping components include a front clamp and a rear clamp, the front clamp and the fixing seat are slidably connected in the front-to-back direction, and an adjusting screw extending horizontally in the front-to-back direction is connected between the front clamp and the fixing seat, wherein the adjusting screw is rotationally connected to the fixing seat and the adjusting screw is threadedly connected to the front clamp. Clamping and fixing the steel bars with the front clamp and the rear clamp can prevent the steel bars from shifting during the marking process, and can also prevent the cylindrical steel bars from rolling during the marking process.

[0011] Preferably, the grooves are opened on the front of the movable block, and a horizontal ruler is arranged on the front of the base, so that the operator can read the spacing between the grooves conveniently.

[0012] Preferably, a second hand wheel is provided at the end of the adjusting screw rod, and the second hand wheel is used to control the rotation of the adjusting screw rod so as to control the sliding of the front clamping member. BRIEF DESCRIPTION OF THE DRAWINGS
