Description

TECHNICAL FIELD

[0001] The utility model relates to the production technology field of ruler, specifically a positioning mechanism of engraver for ruler manufacturing. BACKGROUND

[0002] In the ruler manufacturing industry, engraving is an indispensable process. Traditional engraver positioning mechanisms mostly use mechanical fixing methods, such as clamps, buckles, etc., to position and fix the ruler. However, these traditional methods have many shortcomings.

[0003] Mechanical fixing methods often require tedious adjustments before operation to ensure that the ruler is accurately and stably fixed. This process not only consumes time and effort, but also is prone to errors due to improper human operation, affecting the precision and quality of engraving. In addition, mechanical fixing methods may lead to inaccurate positioning and further affect the engraving effect due to wear and tear and loosening after long-term use. Traditional engraver positioning mechanisms have limitations in adapting to rulers of different lengths and sizes. Due to the fixed nature of mechanical structures, special adjustments or replacement of clamps are often required for rulers of different sizes, which not only increases the difficulty and cost of operation, but also reduces the versatility and flexibility of the equipment. SUMMARY

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] Further, another connecting shaft is rotatably connected with another mounting plate.

[0008] Further, the placement slot is located on the same plane as the outer surface of the limiting plate near the inner wall of the rotating disc.

[0009] Further, the limiting plate is internally provided with an electromagnet, and the placement block is internally provided with a permanent magnet, and the limiting plate and the placement block are attracted to each other.

[0010] Compared with the prior art, the utility model has the beneficial effects that:

[0011] 1. Through the cooperation of the electromagnet and the permanent magnet, the placement block is quickly and accurately positioned and fixed on the limiting plate. When the electromagnet is powered on, it can quickly and stably attract the placement block, avoiding errors and loosening problems that may be caused by traditional mechanical fixing methods. At the same time, this design allows the operator to conveniently adjust the position of the placement block as needed, improving the flexibility and efficiency of the operation.

[0012] 2. The design of the rotating disc and the limiting rod allows the limiting plate to move linearly along a specific trajectory, thereby driving the placement block and the ruler thereon to be accurately clamped and fixed. This design ensures that the ruler maintains a stable posture during engraving, reducing engraving errors caused by shaking or deviation. In addition, by adjusting the position of the limiting rod and the rotation angle of the rotating disc, the device can adapt to rulers of different lengths and sizes, improving the versatility and flexibility of the device.

[0013] 3. After engraving is completed, the limiting plate is reset by the second motor, so that the placement block no longer fixes the ruler. The ruler then falls from under the rotating disc and is collected, facilitating subsequent reuse or disposal. This design not only simplifies the collection process of the ruler, but also reduces the cost and time of manual handling and disposal. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION Example 1

[0016] Please refer to Figure 1The positioning mechanism of a ruler manufacturing engraving machine includes mounting plates 1, a first motor 4, and a second motor 7. Two mounting plates 1 are provided with a movable plate 2. The movable plate 2 is fixedly connected with connecting shafts 3 on both sides. The first motor 4 is fixedly connected to the side of one of the mounting plates 1 away from the movable plate 2. The driving end of the first motor 4 is fixedly connected with one of the connecting shafts 3. A slot 5 is formed through the top of the movable plate 2. Two connecting plates 6 are symmetrically fixedly connected to the inner rear wall of the slot 5. The second motor 7 is fixedly connected to the top of the connecting plate 6. The driving end of the second motor 7 is fixedly connected with a driving rod 8. The top end of the driving rod 8 is fixedly connected with a rotating disc 9. Limiting rods 10 are fixedly connected to the upper and lower surfaces of the end of the rotating disc 9 away from the driving rod 8. Limiting plates 12 are provided above and below the rotating disc 9. A second fixed groove 14 is formed in the outer surface of the limiting plate 12 close to the rotating disc 9. The limiting rods 10 are slidingly connected in the second fixed groove 14. A first fixed groove 13 is formed in the outer surface of the limiting plate 12 away from the rotating disc 9. A plurality of placement blocks 15 are equidistantly arranged in the first fixed groove 13. A placement groove 16 is formed in the outer surface of the placement block 15 away from the rotating disc 9. Two limiting grooves 11 are symmetrically formed in the inner front and rear walls of the slot 5. The front and rear ends of the limiting plate 12 are slidingly connected in the two limiting grooves 11.

[0017] The other connecting shaft 3 is rotatably connected with the other mounting plate 1. This design change means that the entire positioning mechanism is more structurally stable, as the rotational connection of the connecting shaft 3 with the mounting plate 1 provides additional support and stability. This helps to reduce vibrations and deviations during the engraving process, thereby improving the precision and quality of the engraving.

[0018] The inner wall of the placement groove 16 close to the rotating disc 9 and the outer surface of the limiting plate 12 are in the same plane. This design helps to ensure the stability of the ruler during placement and clamping. When the inner wall of the placement groove 16 and the outer surface of the limiting plate 12 are flush, the ruler can be placed more smoothly in the placement groove 16, and will not be subject to additional resistance or friction during clamping. This helps to reduce damage to the ruler and improve the accuracy of positioning.

[0019] The inside of the limiting plate 12 is provided with an electromagnet, and the inside of the placement block 15 is provided with a permanent magnet. The limiting plate 12 and the placement block 15 are attracted to each other. Through the cooperation of the electromagnet and the permanent magnet, the placement block 15 is quickly and accurately positioned and fixed on the limiting plate 12. This non-contact fixing method not only improves the convenience of operation, but also helps to reduce wear and noise caused by mechanical friction. At the same time, the energization and de-energization of the electromagnet can conveniently control the fixation and release of the placement block 15, thereby realizing automatic operation.

[0020] The working principle of the utility model is: when using the positioning mechanism of the engraving machine for ruler manufacturing, because multiple placing blocks 15 are internally provided with permanent magnets and the limiting plate 12 is internally provided with electromagnets, when the electromagnets of the limiting plate 12 are not electrified, the operator can place multiple placing blocks 15 in the interior of the first fixed groove 13 of the limiting plate 12 according to needs, when the electromagnets of the limiting plate 12 are electrified, the limiting plate 12 adsorbs and fixes the placing blocks 15 in the first fixed groove 13, which can prevent the placing blocks 15 from moving, then the operator places the to-be-engraved ruler in the placing groove 16 on the multiple placing blocks 15 in turn, so that the two ends of the ruler are located in the placing groove 16 on the two placing blocks 15, then the second motor 7 drives the driving rod 8 to drive the rotating disc 9 to rotate around the central axis of the driving rod 8, so that the limiting rod 10 on the rotating disc 9 rotates in a circle, and the limiting rod 10 is clamped in the second fixed groove 14 of the limiting plate 12, so that the limiting rod 10 can drive the limiting plate 12 to move linearly along the limiting groove 11 of the interior wall of the slot 5, so that the two limiting plates 12 above the two rotating discs 9 move towards each other, which reduces the distance between the two placing blocks 15 at the two ends of the ruler, so that the placing groove 16 of the two placing blocks 15 clamps and fixes the ruler, which is beneficial to the engraving machine to engrave the ruler. Then the first motor 4 drives the connecting shaft 3 to drive the movable plate 2 to rotate and turn over, so that the ruler moves to the lower side of the rotating disc 9, then the second motor 7 drives the limiting plate 12 to reset, so that the placing block 15 no longer fixes the ruler, and the ruler located below the rotating disc 9 falls and is collected, and the placing groove 16 of the placing block 15 located above the rotating disc 9 can place the ruler.
