Description

Technical Field

[0001] This utility model relates to the field of writing board cutting technology, and in particular to a writing board cutting and positioning device. Background Technology

[0002] Writing tablets, widely used in teaching, office, and home environments, have diverse market demands and come in a wide variety of sizes. During production, large-format substrates (such as painted steel plates and glass plates) typically need to be precisely cut into predetermined finished sizes. Rapid and accurate positioning before cutting is crucial for ensuring product dimensions are up to standard and edges are neat. Therefore, developing efficient and adaptable positioning devices is of significant practical importance for improving the production quality and efficiency of writing tablets.

[0003] In existing whiteboard cutting production, the commonly used positioning method is to use mechanical clamps or stops. Specifically, one or more sets of positioning clamps are usually set on the worktable of the cutting machine. These clamps have a relatively simple structure, mostly rigid stops or manual clamps fixed to the T-slots or screw holes reserved in the worktable by bolts and nuts. When processing a whiteboard of a specific size, the operator will first manually adjust the position of each clamp according to the size using measuring tools and lock it. Then, the whiteboard to be cut is placed against these fixed clamps to achieve initial positioning, and then the cutting blade performs the cutting work.

[0004] However, the aforementioned positioning method, which relies on manually adjusting the fixing fixtures, suffers from particularly high operational efficiency when dealing with multi-specification, small-batch production tasks. Its core drawback lies in the fact that when it's necessary to change to processing writing boards of different sizes, operators must interrupt production, use wrenches and other tools to loosen all the fixing bolts of the positioning fixtures one by one, move them to the new position, and then repeatedly measure and align them with rulers and other tools before finally re-tightening them. This entire process is not only cumbersome, time-consuming, and labor-intensive, but the repeated disassembly, assembly, and manual measurement easily introduce cumulative errors, affecting the accuracy and consistency of positioning. This frequent and inefficient changeover adjustment severely restricts the flexibility and overall work efficiency of the production line, failing to meet the demands of modern production for rapid response and flexible manufacturing. Therefore, a writing board cutting and positioning device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a writing board cutting and positioning device, aiming to improve the existing positioning method which requires manual adjustment of the clamps. When changing to writing boards of different sizes, the operation is cumbersome, time-consuming, and prone to errors. This repetitive and inefficient changeover adjustment leads to low work efficiency and production flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a writing board cutting and positioning device, comprising a mounting plate, wherein a writing board body is disposed on the upper surface of the mounting plate, and a positioning component is installed on one side of the outer wall of the mounting plate;

[0007] The positioning assembly includes a fixing plate, one side of the outer wall of the fixing plate is fixedly connected to one side of the outer wall of the mounting plate, the upper surface of the fixing plate is fixedly connected to symmetrical fixing blocks, one side of the outer wall of the fixing blocks is fixedly connected to a limit rod, a connecting block is fixedly connected between the two fixing blocks, one side of the outer wall of the connecting block is fixedly connected to a hydraulic rod, the output end of the hydraulic rod is fixedly connected to a connecting plate, one side of the outer wall of the connecting plate is fixedly connected to an L-shaped block, the L-shaped block is slidably connected to the outer wall of the limit rod, the other side of the outer wall of the connecting plate is rotatably connected to symmetrical limit wheels, the upper surface of the mounting plate is fixedly connected to a slide rail near the writing board body, the outer wall of the slide rail is fitted with a slider, and a quick-release assembly is installed inside the slider.

[0008] As a further description of the above technical solution:

[0009] The quick-release assembly includes a locking block, the outer wall of which is slidably connected to the inside of the slider, and a sliding rod is fixedly connected to the upper surface of the locking block. A spring is sleeved on the outer wall of the sliding rod.

[0010] As a further description of the above technical solution:

[0011] A support plate is fixedly connected to the upper surface of the mounting plate one near the writing board body, and a second mounting plate is fixedly connected to the outer wall of the support plate.

[0012] As a further description of the above technical solution:

[0013] A hydraulic rod is fixedly connected inside the mounting plate 2, and a T-shaped plate is fixedly connected to the output end of the hydraulic rod 2.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the hydraulic rod drives the connecting plate, which in turn pushes the writing board body closer to the slider, thus quickly positioning the writing board body. When the connecting plate moves, it slides on the outer wall of the limiting rod, thereby achieving a stable pushing effect on the writing board body. At the same time, by pulling the sliding rod, the locking block can be retracted into the slider, and pulling the slider can achieve the positioning effect according to the writing board body of different sizes. This solves the problem of reduced work efficiency caused by the need to repeatedly change the position of the clamp to position the writing board body in traditional positioning devices, thereby improving the practicality of the device.

[0024] 2. In this utility model, the T-shaped plate is pushed down by the hydraulic rod 2. At this time, the T-shaped plate 1 drives the limiting wheel 2 to abut against the upper surface of the writing board body. At the same time, the extension and contraction of the spring 2 drives the limiting rod 2 to slide within the T-shaped plate 1, thereby achieving the effect of facilitating the positioning and stabilization of writing board bodies of various sizes. Meanwhile, the rotation of the limiting wheel 2 ensures that the limiting wheel 1 will not cause jamming when pushing the writing board body, thus improving the practicality of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-4 An embodiment of this utility model is provided: a writing board cutting and positioning device, including a mounting plate 1 as a support platform for the entire device, the upper surface of the mounting plate 1 is used to place the writing board body 2 to be processed, and a set of positioning components for performing positioning actions is installed on one side of the outer wall of the mounting plate 1.

[0033] The positioning assembly includes a fixing plate 3 as its basic structure. One side of the outer wall of the fixing plate 3 is firmly fixed to one side of the outer wall of the mounting plate 1 to ensure the stable installation of the positioning assembly. The upper surface of the fixing plate 3 is fixedly connected to fixing blocks 4 that are symmetrically distributed on the left and right. The fixing blocks 4 provide reliable support points for other components. One side of its outer wall is fixedly connected to a limiting rod 5 that serves as a guide rail. Between the two fixing blocks 4, a connecting block 6 for installing a power element is also fixedly connected. One side of the outer wall of the connecting block 6 is fixedly connected to a hydraulic rod 7 that provides the active force. The output end of the hydraulic rod 7 is fixedly connected to a connecting plate 9 for transmitting thrust. One side of the outer wall of the connecting plate 9 is fixedly connected to an L-shaped block 8. The interior of the L-shaped block 8 is slidably fitted onto the outer wall of the limiting rod 5 to ensure the smooth and precise guidance of the connecting plate 9 during movement. The other side of the outer wall of the connecting plate 9 is also rotatably connected to a limiting wheel 10 that is symmetrical on the left and right and directly contacts the writing board body 2. Meanwhile, a slide rail 11 for setting a positioning reference is fixedly connected to the upper surface of the mounting plate 1 near the writing board body 2. A slider 12 that can move along the slide rail 11 is installed on the outer wall of the slide rail 11. A quick-release assembly for fast locking and releasing is installed inside the slider 12. The quick-release assembly includes a locking block 13 that performs the locking function. The locking block 13 can slide up and down inside the slider 12. A handle slide bar 14 for the operator to pull is fixedly connected to the upper surface of the locking block 13. A spring 15 for providing a reset elastic force is sleeved on the outer wall of the slide bar 14. The upper end of the spring 15 is fixedly connected to the top wall of the inner cavity of the slider 12, and its lower end is fixedly connected to the upper surface of the locking block 13 to continuously apply downward pressure to the locking block 13.

[0034] Specifically, firstly, by pulling the slide bar 14 to overcome the elastic force of the spring 15, the locking block 13 disengages from the slide rail 11. The operator can then quickly move the slider 12, which serves as the positioning reference, along the slide rail 11 to a position suitable for the current width of the writing tablet body 2. After releasing the lever, the locking block 13 automatically resets and locks under the action of the spring 15. Then, the writing tablet body 2 is placed on the mounting plate 1, with one side pressed against the fixed slider 12. At this time, the hydraulic rod 7 is activated, and its output end pushes the connecting plate 9 forward smoothly under the guidance of the limit rod 5. This, in turn, pushes the other side of the writing tablet body 2 tightly through the limit wheel 10 until it is completely against the slider 12, thus completing the rapid, accurate, and stable lateral positioning of the writing tablet.

[0035] Reference Figures 1-4On the upper surface of mounting plate 1, near the writing board body 2, a support plate 16 is fixedly connected to support it. On the outer wall of support plate 16, mounting plate 2 17 for mounting the top clamping mechanism is fixedly connected. The interior of mounting plate 2 17 is used to fix a hydraulic rod 2 18 that provides vertical power. The output end of hydraulic rod 2 18 extends downward and is fixedly connected to T-shaped plate 19 as the main moving part. The interior of T-shaped plate 19 is slidably connected to a limiting rod 20 for vertical guidance. The lower end of limiting rod 20 is fixedly connected to T-shaped plate 21 as the final clamping actuator. The lower surface of T-shaped plate 21 is fixedly connected to multiple limiting wheels 23 that contact the upper surface of writing board body 2. The outer wall of limiting rod 20 is fitted with spring 22 for buffering and applying pressure. The upper end of spring 22 is fixedly connected to the lower surface of T-shaped plate 19, and its lower end is fixedly connected to the upper surface of T-shaped plate 21, forming an elastic connection structure.

[0036] Specifically, the writing tablet body 2 is stabilized vertically during or after lateral positioning. During operation, hydraulic rod 18 is activated, its output end pushing T-shaped plate 19 downwards. The descent of T-shaped plate 19 compresses spring 22 between it and T-shaped plate 21. Spring 22 then generates elastic force, which is evenly applied to T-shaped plate 21, and then gently pressed against the upper surface of the writing tablet body 2 by multiple limiting wheels 23 below it. The presence of spring 22 makes the pressing force elastic, automatically compensating for and adapting to slight differences in writing tablet thickness, ensuring reliable pressing. Simultaneously, the rolling characteristics of the limiting wheels 23 effectively prevent scratches or movement jamming on the upper surface of the writing tablet body 2 due to friction when the lateral positioning mechanism pushes it, ensuring the smoothness and accuracy of the entire positioning process and achieving a stable and non-destructive positioning effect.

[0037] Working principle: When using this cutting and positioning device, firstly, the device is quickly adjusted according to the size of the writing board body 2 to be processed. The operator pulls the slide bar 14 upward, which causes the locking block 13 to move upward inside the slider 12 and compress the spring 15. After the locking block 13 is fully retracted into the slider 12, the slider 12 can be easily slid left and right along the slide rail 11 to move it to the preset reference position. After releasing the slide bar 14, the elasticity of the spring 15 will cause the locking block 13 to return to its original position and engage with the structure of the slide rail 11, thereby firmly locking the slider 12.

[0038] Secondly, after adjustment, place the writing tablet body 2 on the mounting plate 1, with one side roughly against the slider 12. Then, activate the positioning assembly; the piston rod of the hydraulic rod 7 extends and pushes the connecting plate 9. Under the constraint of the L-shaped block 8, the connecting plate 9 moves forward steadily along the limit rods 5 on both sides. The limit wheel 10 rotating on it will then abut against and push the side wall of the writing tablet body 2 until its other side is completely against the positioned slider 12. Thus, the rapid lateral positioning of the writing tablet is completed.

[0039] Finally, simultaneously with or after the lateral positioning, the top clamping mechanism is activated. The hydraulic rod 18, installed within the mounting plate 17, is activated, its output end pressing down on the T-shaped plate 19. The T-shaped plate 19 transmits force to the T-shaped plate 21 via spring 22, causing the multiple limiting wheels 23 below the T-shaped plate 21 to press firmly against the upper surface of the writing board body 2, achieving stable vertical clamping. After the entire process is completed, the writing board body 2 is precisely positioned and securely clamped in both the lateral and vertical directions, ready for subsequent cutting processes.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
