Description

Technical Field

[0001] This utility model belongs to the technical field of steel plate sampling tools, specifically relating to a steel plate sampling and marking device. Background Technology

[0002] Steel plate sampling typically involves selecting one or more surfaces or lines on its upper surface as references for scribing. These references should ensure accurate sampling locations and facilitate subsequent processing and inspection. After scribing, workers can easily punch center punches at key locations such as the intersections of the scribing lines, the start and end points of arcs, ensuring clear and accurate center punches for easy positioning during subsequent processing and inspection.

[0003] Sampling and marking of steel plates typically involves using tools such as steel rulers, vernier calipers, steel tape measures, scribers, and stone pencils to draw multiple straight lines on the surface of the steel plate. These lines can be parallel to each other or partially perpendicular.

[0004] Some manufacturers choose to combine multiple steel rulers so that they can slide against each other to draw multiple straight lines. However, combined rulers have multiple degrees of freedom. When drawing more than two lines, it is necessary to hold down two of the parts by hand, which is difficult to operate and inconvenient to hold the reference part steady. Utility Model Content

[0005] The purpose of this invention is to provide a steel plate sampling and marking device. By pressing down on the reference ruler and stabilizing the reference part, the entire marking device can be positioned, freeing up the hands to mark lines and facilitating independent operation by a single person.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A steel plate sampling and marking device includes a reference ruler with a hook-shaped slide rail fixed to its surface. A slider is connected to the outside of the reference ruler via the slide rail. The slider is hollow and adapted to fit the hook-shaped slide rail. A first locking bolt and a secondary ruler penetrated by the first locking bolt are provided at the top of the slider. A rotating shaft passes through the end of the secondary ruler away from the reference ruler. A strip plate connected to the end of the rotating shaft is provided on the outside of the secondary ruler, and a second locking bolt passes through the end of the strip plate away from the secondary ruler. When sampling the steel plate, a reference line is first marked along the scale of the reference ruler in the target area. Move the slider and corresponding vernier scale to the designated position, so that two strip plates are distributed between two adjacent vernier scales. The second locking bolt is initially in a loose state. Once the vernier scale is in place, tighten the nut of the second locking bolt to lock the two adjacent strip plates. At the same time, tighten the first locking bolt along the thread until it is pressed against the reference scale. Use friction to lock the slider and vernier scale. Another line can be drawn along the scale of the vernier scale. Since the two ends of the vernier scale are limited by the first locking bolt and the strip plates respectively, hold the reference scale and stabilize the part used as the reference to position the entire marking device. This frees up your hands to draw lines and is conducive to independent operation by one person.

[0008] As an alternative, a hemispherical seat is fixed at the end of the rotating shaft away from the strip plate. A ball bearing is rotatably installed at the opening of the hemispherical seat. During movement, the auxiliary scale supports the rotating shaft through the bearing to prevent the rotating shaft from falling off. When the ball bearing at the opening of the hemispherical seat contacts the steel plate, it rotates, so that the rotating shaft and the slider support the auxiliary scale from both sides, preventing the auxiliary scale from tilting when under pressure, and without hindering the movement of the auxiliary scale.

[0009] As an alternative, anti-slip rubber strips and pressing plates are fixed on both sides of the reference ruler, and both the anti-slip rubber strips and the pressing plates avoid the slide rail.

[0010] As an alternative, the inner side of the slider is provided with an oil storage groove that communicates with the inside of the slide rail, and an oil-absorbing felt that contacts the inner wall of the slide rail is fixed inside the oil storage groove.

[0011] As an alternative, the top of the slider is provided with a positioning hole that is offset from the first locking bolt, and one end of the auxiliary ruler is fixed with a positioning pin that matches the positioning hole.

[0012] As an alternative, the second locking bolt is fitted with a rubber ring and a frosted ring, with the end face of the rubber ring fixed to one side of the strip plate.

[0013] As an alternative, the bottom of the auxiliary ruler is integrally fitted with a protrusion, one side of which is provided with a scale and the other side is fixed with a silicone pad.

[0014] The technical effects achieved by this utility model are as follows:

[0015] When sampling steel plates, this invention first draws a baseline line along the scale of a reference ruler in the target area. The slider and corresponding secondary ruler are then moved to a designated position, resulting in two strip plates distributed between two adjacent secondary rulers. The second locking bolt is initially loose. Once the secondary ruler is in place, the nut of the second locking bolt is tightened to lock the two adjacent strip plates. Simultaneously, the first locking bolt is tightened along the thread until it presses against the reference ruler. Friction is used to lock the slider and secondary ruler, allowing another line to be drawn along the scale of the secondary ruler. Since both ends of the secondary ruler are limited by the first locking bolt and the strip plates respectively, holding the reference ruler steady on the reference part allows the entire marking device to be positioned, freeing up the hands for marking and facilitating independent operation by a single person.

[0016] In this invention, during movement, the auxiliary ruler supports the rotating shaft through bearings to prevent the rotating shaft from falling off, and rotates when the ball bearings at the opening of the hemispherical seat contact the steel plate, so that the rotating shaft and the slider support the auxiliary ruler from both sides, preventing the auxiliary ruler from tilting when under pressure, and without hindering the movement of the auxiliary ruler.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-6 As shown, a steel plate sampling and marking device includes a reference ruler 1. One side of the reference ruler 1 has graduations, and the other side is welded with a hook-shaped long straight slide rail 2. When sampling the steel plate, a reference line is first drawn along the graduations of the reference ruler 1 in the target area. A slider 3 is connected to the outside of the reference ruler 1 via the slide rail 2. In this embodiment, the inside of the slider 3 is hollow to fit the hook-shaped slide rail 2, preventing the slider 3 from slipping. By moving the slider 3, a first locking bolt 5 is located on the top of the slider 3, and a secondary ruler 4, through which the first locking bolt 5 passes, is moved to a designated position. This embodiment uses two secondary rulers 4 spaced apart, allowing them to move independently. The number of secondary rulers 4 can also be increased. A rotating shaft 6 passes through the end of the secondary ruler 4 furthest from the reference ruler 1, and a rotating shaft 6 is provided on the outside of the secondary ruler 4. The strip plate 7 connected to the end of the rotating shaft 6 distributes two strip plates 7 between two adjacent secondary scales 4. The end of the strip plate 7 away from the secondary scale 4 is through which the second locking bolt 8 passes. The second locking bolt 8 is initially in a loose state. Once the secondary scale 4 is in place, the nut of the second locking bolt 8 can be tightened to lock the two adjacent strip plates 7. At the same time, the first locking bolt 5 is tightened along the thread until it is pressed against the reference scale 1. The friction action locks the slider 3 and the secondary scale 4. Since the secondary scale 4 is perpendicular to the reference scale 1, another line can be drawn along the scale of the secondary scale 4. Since the two ends of the secondary scale 4 are limited by the first locking bolt 5 and the strip plate 7 respectively, by holding the reference scale 1 and stabilizing the reference part, the entire marking device can be positioned, which makes it convenient to free up the hands to draw lines and is conducive to single-person independent operation.

[0027] The second locking bolt 8 is in a loose state, which allows the two strip plates 7 to swing around it, so that the angle between the two strip plates 7 increases as the distance between the two auxiliary scales 4 increases, or decreases as the distance between the two auxiliary scales 4 decreases.

[0028] See attached document Figure 1 and Figure 2 To facilitate manual operation, in this embodiment, anti-slip strips 101 and pressing plates 102 are respectively attached to both sides of the reference ruler 1. Both anti-slip strips 101 and pressing plates 102 can be made of anti-slip rubber. After the anti-slip strips 101 contact the surface of the steel plate and are in place, the pressing plates 102 can be pressed down by hand to fit the reference ruler 1 tightly, making it easy for the hand to avoid the sharp edge of the reference ruler 1. Since both the anti-slip strips 101 and pressing plates 102 avoid the slide rail 2, they will not block the slider 3 and the auxiliary ruler 4.

[0029] See attached document Figure 2 , Figure 3 and Figure 5 During the movement, the auxiliary ruler 4 supports the rotating shaft 6 through the bearing to prevent the rotating shaft 6 from falling. In this embodiment, a hemispherical seat 601 is welded to the end of the rotating shaft 6 away from the strip plate 7, and a ball bearing 602 is rotatably installed at the opening of the hemispherical seat 601 for rotation when in contact with the steel plate. This allows the rotating shaft 6 and the slider 3 to support the auxiliary ruler 4 from both sides, preventing the auxiliary ruler 4 from tilting when under pressure, and also not hindering the movement of the auxiliary ruler 4.

[0030] See attached document Figure 1 , Figure 2 and Figure 4 The inner side of the slider 3 is provided with an oil storage groove 301 that communicates with the inside of the slide rail 2. The oil storage groove 301 is used to hold lubricating oil and to lubricate the slide rail 2 and the slider 3. In this embodiment, an oil-absorbing felt 302 that contacts the inner wall of the slide rail 2 is bonded inside the oil storage groove 301. When the oil-absorbing felt 302 is saturated with lubricating oil, it can apply the lubricating oil to the slide rail 2 as the slider 3 moves.

[0031] See attached document Figure 2 and Figure 6 The second locking bolt 8 is fitted with a rubber ring 701 and a frosted ring 702. The end face of the rubber ring 701 is fixed to one side of the strip plate 7. When the second locking bolt 8 is in the loose state, it is convenient to swing the two strip plates 7. The rubber ring 701 and the frosted ring 702 separate the two strip plates, allowing the rubber ring 701 to rotate freely relative to the frosted ring 702. After the nut of the second locking bolt 8 is tightened, the friction between the rubber ring 701 and the frosted ring 702 increases. The rubber ring 701 is relatively thin, so the strip plate 7 will not shake due to the deformation of the rubber ring 701.

[0032] See attached document Figure 1 , Figure 2 and Figure 3 During the movement, the center of gravity of the auxiliary ruler 4 is lowered by the protrusion 402 integrated on the bottom of the auxiliary ruler 4, so that the auxiliary ruler 4 is closer to the steel plate. The protrusion 402 has a scale on one side, which makes it convenient for the staff to draw lines closer to the steel plate, and a silicone pad 403 is attached to the other side, which can be held by hand to move the auxiliary ruler 4.

[0033] See attached document Figure 1 and Figure 4 The top of the slider 3 has a positioning hole 303 that is offset from the first locking bolt 5. One end of the auxiliary ruler 4 is fixed with a positioning pin 401 that matches the positioning hole 303. When installing the auxiliary ruler 4, at least two positioning pins 401 can be inserted into the positioning hole 303 respectively to make the auxiliary ruler 4 quickly align with the slider 3. Then tighten the first locking bolt 5 to lock the slider 3 and the auxiliary ruler 4. Then, the first locking bolt 5 can be unscrewed to disassemble the auxiliary ruler 4 for easy carrying of the scribing device.

[0034] The working principle of this utility model is as follows: When sampling steel plates, a baseline line is first drawn along the scale of the reference ruler 1 in the target area. By moving the slider 3, the slider 3 and the corresponding secondary ruler 4 are moved to the designated position, so that two strip plates 7 are distributed between two adjacent secondary rulers 4. The second locking bolt 8 is initially in a loose state. Once the secondary ruler 4 is in place, the nut of the second locking bolt 8 can be tightened to lock the two adjacent strip plates 7. At the same time, the first locking bolt 5 is tightened along the thread until it is pressed against the reference ruler 1. The slider 3 and the secondary ruler 4 are locked by friction. Another line can be drawn along the scale of the secondary ruler 4. Since the two ends of the secondary ruler 4 are limited by the first locking bolt 5 and the strip plate 7 respectively, it is only necessary to hold the reference ruler 1 and stabilize the part used as the reference to position the entire marking device, which makes it convenient to free up hands to draw lines and is conducive to single-person independent operation.

[0035] The above description is merely an optional embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
