Description

Technical Field

[0001] The present application relates to the technical field of devices for testing the mechanical properties of steel bars, and in particular to a steel bar laser distance measuring device. Background Art

[0002] The yield strength, tensile strength and elongation of steel can be obtained through tensile testing. Before the test, the length of the steel bar is calibrated by marking points on the surface of the steel bar with a steel bar gauge, so as to measure the elongation, cross-sectional shrinkage and other technical indicators of the steel after the tensile test.

[0003] In the prior art, a person usually places the steel bar under the clamping member, and then adjusts the screw rod to drive the clamping member to contact the steel bar to clamp the steel bar. This clamping method is time-consuming and labor-intensive, and the clamping effect is not good. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides a steel bar laser marking device, which has the advantages of being easy to clamp the steel bars, etc., and solves the problem that personnel usually place the steel bars under the clamping member, and then adjust the screw to drive the clamping member to contact the steel bars to achieve clamping of the steel bars. This clamping method is time-consuming and labor-intensive, and the clamping effect is not good.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a steel bar laser marking device, comprising a base plate, a placing seat being fixedly connected to one side of the upper end of the base plate, a V-shaped groove being provided on the upper end of the placing seat, a sliding groove being provided on one side of the placing seat, two movable frames being slidably connected inside the sliding groove, limiting holes being provided on the upper ends of the two movable frames, sliding rods being slidably connected inside the two limiting holes, two baffle rods being fixedly connected to the outer walls of the two sliding rods, handles being provided through the upper ends of the two sliding rods, pressure plates being rotatably connected to the bottom ends of the two sliding rods, two springs being fixedly connected to the upper ends of the two pressure plates, and the two springs being fixedly connected to the movable frame on the side away from the pressure plates.

[0006] Through the above scheme, the position of the pressure plate can be adjusted according to the size of the steel bar through the setting of the mobile frame and the sliding rod. This flexibility enables the device to adapt to steel bars of different specifications, improving its versatility and practicality. Through the combination of the sliding rod, the stop rod, the limiting hole and the pressure plate, the steel bar can be firmly fixed in the V-shaped groove. The user pulls the sliding rod upward through the handle to make the pressure plate break away from contact with the steel bar. Then, the user aligns the stop rod with the limiting hole on the mobile frame and releases the sliding rod. Under the action of the spring, the pressure plate will automatically fall and press the steel bar, and the pressure plate can be firmly fixed above the steel bar.

[0007] Furthermore, scales are fixedly provided on both sides of the upper end of the placement seat.

[0008] Through the above scheme, the user can intuitively read the length and gauge information of the steel bars by setting the scale.

[0009] Furthermore, a fixing plate is fixedly connected to the upper end of the base plate, a slide rail is fixedly connected to the upper end of the fixing plate, a threaded column is rotatably connected inside the slide rail, a servo motor is fixedly connected to one side of the slide rail, and an output end of the servo motor is fixedly connected to a threaded rod through a coupling.

[0010] Through the above scheme, an automated moving mechanism is formed by the setting of the servo motor and the threaded column. The servo motor can accurately control the rotation of the threaded column, and then drive the moving rod connected thereto to move on the slide rail, so that the laser device can automatically move to the specified position and perform precise marking operations on the steel bars, thereby improving work efficiency, reducing errors in human operation, and making the marking more accurate and reliable.

[0011] Furthermore, the threaded column is externally threadedly connected to a moving rod, and a laser emitting head is fixedly connected to a side of the moving rod away from the threaded column.

[0012] Through the above solution, since the threaded column and the moving rod are connected by a thread, when the servo motor drives the threaded column to rotate, the moving rod will move precisely linearly along the threaded column. This design ensures that the laser device can be accurately moved to the predetermined position, thereby achieving high-precision steel bar gauge length.

[0013] Furthermore, a control box is fixedly connected to one side of the base plate.

[0014] Through the above solution, the control box serves as the control center of the entire device, which can be centrally managed and operated, and the user can conveniently operate the device through the control box.

[0015] Furthermore, one end of the bottom plate away from the placement seat is fixedly connected to a battery box, and a storage battery is fixedly connected inside the battery box.

[0016] Through the above scheme, by setting a battery box on the bottom plate and building in a storage battery, the device realizes a self-powered function, so that the device can work independently without relying on an external power source, thereby enhancing its portability and flexibility of use.

[0017] Furthermore, an upper cover is rotatably connected to one side of the upper end of the battery box.

[0018] Through the above solution, the user can easily open the battery box by rotating the connected upper cover, thereby conveniently maintaining and replacing the battery.

[0019] Furthermore, the storage battery is electrically connected to the servo motor, the laser transmitting head and the control box respectively.

[0020] Through the above solution, the battery serves as the power source of the entire device, providing a stable and reliable power supply for the servo motor, laser transmitter head and control box.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This kind of steel bar laser marking device, through the setting of the movable frame and the sliding rod, can adjust the position of the pressure plate according to the size of the steel bar. This flexibility enables the device to adapt to steel bars of different specifications, improving its versatility and practicality. Through the combination of the sliding rod, the stop rod, the limiting hole and the pressure plate, the steel bar can be firmly fixed in the V-shaped groove. The user pulls the sliding rod upward through the handle to make the pressure plate break away from the contact with the steel bar. Then, the user aligns the stop rod with the limiting hole on the movable frame and releases the sliding rod. Under the action of the spring, the pressure plate will automatically fall and press the steel bar. Through the restriction of the stop rod and the limiting hole, the pressure plate can be firmly fixed above the steel bar. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the steel bar laser marking device is arranged by a movable frame 5 and a sliding rod 7, so that the position of the pressure plate 10 can be adjusted according to the size of the steel bar. This flexibility enables the device to adapt to steel bars of different specifications, thereby improving its versatility and practicality. Through the combination of the sliding rod 7, the baffle rod 8, the limiting hole 6 and the pressure plate 10, the steel bar can be firmly fixed in the V-shaped groove 3. The user pulls the sliding rod 7 upward through the handle 9 to separate the pressure plate 10 from the contact with the steel bar. Then, the user aligns the baffle rod 8 with the limiting hole 6 on the movable frame 5 and releases the sliding rod 7. Under the action of the spring 11, the pressure plate 10 will automatically fall and press the steel bar. Through the restriction of the baffle rod 8 and the limiting hole 6, the pressure plate 10 can be firmly fixed above the steel bar.

[0034] It should be noted that the slide rod 7 is rotatably arranged inside the limiting hole 6 .

[0035] The working principle of the above embodiment is:

[0036] The user first places the steel bar in the V-groove 3 of the placement seat 2 to ensure that the steel bar fits stably in the V-groove 3 for subsequent gauge operation. The user adjusts the positions of the two mobile frames 5 according to the size of the steel bar to adapt them to the width of the steel bar. By moving the mobile frame 5, it can be ensured that the pressure plate 10 can accurately cover the top of the steel bar. After adjusting the mobile frame 5, the user pulls up the slide bar 7 through the handle 9 to make the pressure plate 10 break away from the contact with the steel bar. Then, the user aligns the blocking rod 8 with the limiting hole 6 on the mobile frame 5 and releases the slide bar 7. Under the action of the spring 11, the pressure plate 10 will automatically fall and press the steel bar. Through the restriction of the blocking rod 8 and the limiting hole 6, the pressure plate 10 can be firmly fixed above the steel bar. The user sets the required gauge parameters through the control box 19. The control box 19 serves as the control center of the entire device. It can receive the user's operating instructions and control each component to perform corresponding actions. Once the gauge length parameters are set, the control box 19 will send instructions to the servo motor 16 to start the automatic movement mechanism. The servo motor 16 starts working and drives the threaded column 15 to rotate inside the slide rail 14 through the coupling. Since the threaded column 15 and the moving rod 17 are threadedly connected, when the threaded column 15 rotates, the moving rod 17 will perform precise linear movement along the slide rail 14, and the laser transmitter 18 will be accurately moved to the predetermined gauge length position. When the laser transmitter 18 moves to the specified position, the control box 19 will send instructions to the laser transmitter 18 to emit laser, and the laser beam will be projected on the steel bar to form a clear gauge length line. The user can mark the steel bar according to the laser gauge length line to ensure that the length and gauge length of the steel bar meet the requirements.
