Description

Technical Field

[0001] This utility model relates to the field of laser cutting and welding, and in particular to a laser bevel adjustment and anti-collision protection device. Background Technology

[0002] With the rapid development of science and technology, laser technology has been widely applied in various fields such as automobiles, machinery, power, scientific research, and 3D printing. Currently, most laser equipment can only operate vertically downwards, and some devices on the market that adjust the laser head angle are motor-driven. This method is complex to install, requiring not only the installation of the motor and its electrical components but also specialized program control. Therefore, motorized beveling devices are complex to install, expensive, have a high failure rate, and high maintenance costs, making them unaffordable for many companies.

[0003] Meanwhile, laser equipment needs to be close to the workpiece when it is working, so it faces many potential risks in the process, such as thermal deformation of the workpiece, deformation and protrusion of the workpiece below, or the workpiece falling and lifting up. These can easily cause the laser head to be hit, resulting in damage or even destruction of the laser head.

[0004] Based on this, a bevel adjustment anti-collision protection device is proposed to adjust the angle of the laser head, enabling the laser equipment, which could only perform vertical operations, to complete more diverse tasks. At the same time, a protective component is added, in the event of an impact, a spring and piston rod eject and slide upward, causing the laser head to slide upward significantly to avoid the impacting object, greatly reducing the damage caused by the impact. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bevel adjustment anti-collision protection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The brass graphite sleeve is installed in the inner hole of an adjustment scale plate. The rotating adjustment plate is fixedly connected to a rotating pressure plate. The rotating adjustment plate has two symmetrical annular elongated holes, and the annular elongated holes are rotatably connected to and limited by the adjustment scale plate.

[0013] As a preferred embodiment of this utility model, the fixed base plate is provided with threaded holes for mounting limit bolts on both sides, which limit the linear sliding of the first anti-collision side plate and the second anti-collision side plate.

[0014] As a preferred embodiment of this utility model, a vertical position detection switch is installed on the outer wall of the top of the anti-collision top plate (6).

[0015] As a preferred embodiment of this utility model, a vertical position detection switch 2 is installed on the outer wall of the top of the anti-collision top plate (6).

After inspection and reset, it effectively avoids secondary damage and improves the safety and reliability of the equipment.

[0032] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0034] Bevel adjustment anti-collision protection device, such as Figures 1 to 7As shown, the assembly includes a bevel adjustment component for adjusting the angle and a collision protection component for protecting the laser head. The bevel adjustment component includes a rotating adjustment plate 9, an adjustment scale plate 10, a rotating pressure plate 11, and a brass graphite sleeve 12. The brass graphite sleeve 12 is installed in the inner hole of the adjustment scale plate 10. A boss on the rotating adjustment plate 9 passes through the inner hole of the brass graphite sleeve 12. The height of the boss is flush with the cylindrical groove plane on the back of the adjustment scale plate 10. The boss has a threaded hole and is fixed by the rotating pressure plate 11. The diameter and height of the rotating pressure plate 11 are slightly smaller than the diameter and height of the cylindrical groove on the back of the adjustment scale plate 10 to avoid interference between them. The inner hole of the scale plate 10 is interference-fitted with the brass graphite sleeve 12, and the inner hole of the brass graphite sleeve 12 is clearance-fitted with the boss on the rotary adjustment plate 9. The boss on the rotary adjustment plate 9 can rotate relative to the scale plate 10 within the inner hole of the brass graphite sleeve 12. The protective components include a fixed base plate 1, an anti-collision sliding plate 2, a guide rail 3, a slider 4, an anti-collision base plate 5, an anti-collision top plate 6, an anti-collision side plate 1 7 and an anti-collision side plate 2 8, a vertical position detection switch 1 14, a vertical position detection switch 2 15, a buffer spring 16, a strong magnet 17, a piston rod 18, a sealing ring 1 19, a rod limiting component 20, and a sealing ring 2 21. The system includes an adjustable L-shaped air pipe connector 22, an ejector solenoid valve 23, an L-shaped air pipe connector 24, an air pipe connector 25, a tee connector 26, a limit bolt 27, and an air pipe 28. A guide rail 3 is mounted on the fixed base plate 1, and a matching slider 4 is mounted on the guide rail 3. An anti-collision sliding plate 2 is mounted on the slider 4. An anti-collision base plate 5 is mounted at the bottom of the fixed base plate 1, and an anti-collision top plate 6 is mounted at the top of the anti-collision sliding plate 2. Anti-collision side plates 7 and 8 are respectively mounted on the left and right sides of the anti-collision sliding plate 2. The upper surface of the fixed base plate 1 has countersunk holes, in which strong magnets 17 are installed. A buffer is also installed in the central countersunk hole. A spring is used to buffer the impact of the piston rod retracting and the laser head falling freely after the impact factor is eliminated; two sets of piston holes are provided on the lower surface of the fixed base plate 1, and piston rods 18 are installed in the holes. A sealing ring 19 is installed on the piston rod 18 and fits tightly with the piston hole of the fixed base plate 1; anti-collision side plate 1 7 and anti-collision side plate 2 8 are respectively provided with threaded holes corresponding to the through holes on both sides of the fixed base plate 1, and adjustable L-shaped air pipe connectors 22 are installed. The two sets of adjustable L-shaped air pipe connectors (22) are connected to the ejection solenoid valve (23) through the air pipe 28 and the three-way connector (26), and the ejection solenoid valve (23) is normally closed.

[0035] The laser head 13 can be installed on the rotating adjustment plate 9, and the fixed base plate 1 can be installed on the laser machine tool. The bevel adjustment component and the collision protection component are fixed together by bolts. The annular elongated hole 30 on the rotating adjustment plate 9 and the corresponding threaded hole on the adjustment scale plate 10 can fix the angle of the laser head 13. At the same time, the angle of the laser head 13 can be adjusted according to the scale on the adjustment scale plate 10 and the pointer position on the rotating adjustment plate 9.

[0036] Furthermore, when the laser head 13 encounters an impact during operation, the adsorption between the anti-collision top plate 6 and the strong magnet 17 is broken, and the anti-collision sliding plate 2 can slide freely relative to the fixed base plate 1 under the guidance of the guide rail 3 and the slider 4, thereby effectively mitigating the impact force generated by the impact and protecting the laser head 13 from damage. In this embodiment, the number of sliders and guide rails is preferably two sets.

[0037] The anti-collision top plate 6 is equipped with a vertical position detection switch 14 and a vertical position detection switch 15 to monitor the position changes of the laser head 13 in real time. If the laser head 13 is displaced during an impact, the vertical position detection switches 14 and 15 can quickly detect this and send an alarm signal, causing the machine tool to stop immediately. Simultaneously, the solenoid valve is activated, high-pressure gas rushes into the piston hole of the fixed base plate, the piston rod pops out, lifting the laser head away from the impact object; it then awaits inspection and reset. This design not only improves the safety and reliability of the equipment but also effectively avoids secondary injuries.

[0038] Working principle: such as Figure 6 As shown, after the bevel adjustment assembly is installed, if the bottom cut surface of the rotating adjustment plate 9 is flush with the bottom cut surface of the adjustment scale plate 10, and the arrow on the rotating adjustment plate 9 points to the zero position of the adjustment scale plate 10, it indicates that the laser head 13 is vertically downward. At this time, the direction of the laser head 13 can be fixed by bolting through the annular elongated hole 30 on the rotating adjustment plate 9 and the threaded hole on the adjustment scale plate 10; the bevel adjustment assembly rotates through the cylindrical boss of the rotating adjustment plate 9 and the inner hole of the brass graphite sleeve 12 installed on the adjustment scale plate 10, and is adjusted to the required angle with the help of the arrow markings and angle markings, and then fixed with bolts. In this way, the cutting angle of the laser head can be changed, allowing the laser head, which could only perform vertical operations, to complete more diverse tasks; such as Figure 7As shown, under normal operating conditions, the collision protection component, under the gravity of the laser head 13 and the bevel adjustment component, and the magnetic attraction of the strong magnet 17 to the anti-collision top plate 6, keeps the bottom of the anti-collision sliding plate 2 in contact with the anti-collision base plate 5 to maintain the positional stability of the laser head 13 during operation. After an impact, the impact force must overcome gravity and magnetic attraction to move the laser head 13 upward until the limiting bolts installed on the fixed base plate 1 reach the upper limit position of the upper limit strip holes of the anti-collision side plate 1 7 and the anti-collision side plate 2 8, or when the impact does not reach the limit position, the vertical position detection device installed on the anti-collision top plate 6 will activate. When the vertical position detection switch 14 and vertical position detection switch 2 15 sense the displacement of the laser head, an alarm signal is sent. At the same time, the ejector solenoid valve (23) also receives the signal, the valve is connected, high-pressure gas is filled into the piston hole of the fixed base plate, the piston rod pops out, and lifts the laser head 13 away from the impact object; this buffers the damage caused by the impact to protect the laser head 13. At the same time, the machine tool stops running and waits for inspection and reset to avoid secondary damage. After the impact factor is eliminated, the solenoid valve closes, the gas in the two sets of piston holes on the lower surface of the fixed base plate 1 is discharged from the L-shaped gas pipe joint, the piston rod 18 retracts, and the buffer spring 16 buffers the impact of the laser head falling freely.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
