Description

Technical Field

[0001] This utility model relates to the technical field of disassembling round nuts in machining equipment, specifically to a round nut adjustment device for the laser head of a laser cutting machine. Background Technology

[0002] In the field of laser cutting equipment, the precise adjustment of the laser head is crucial to processing accuracy. The round nut used in the laser head adjustment device operates on the principle of self-locking based on the friction between the nut and bolt. However, under the vibration and dynamic load conditions of a laser cutting machine during operation, the reliability of this self-locking significantly decreases. To ensure the stability of the laser head position during high-speed processing, special anti-loosening measures must be taken. The use of locking round nuts in conjunction with anti-loosening washers has become a key anti-loosening solution in laser equipment. Round nuts specifically designed for laser cutting machines typically have 4, 6, or 8 rectangular notches on their circumference. The number of these notches varies depending on the laser head size and the design standards of different manufacturers. These notches not only serve as the leverage points for the adjustment tool but also as the positioning points for the anti-loosening washers. This dual-function design optimizes the ease of laser head adjustment while ensuring anti-loosening reliability under high-frequency vibration environments.

[0003] Currently, the main tool used for adjusting these round nuts in laser equipment maintenance is the crescent wrench. However, this traditional tool has significant limitations: its fixed opening size cannot accommodate round nuts of different laser head sizes. This necessitates the use of multiple wrenches when maintaining different models of laser cutting machines, increasing maintenance costs and reducing work efficiency. The limitations of traditional tools are particularly pronounced on high-precision equipment like laser cutting machines that require frequent adjustments and maintenance. Therefore, developing a dedicated adjustment device with an adjustable opening size that can accommodate round nuts of various laser head sizes is crucial for improving the maintenance efficiency and reducing operating costs of laser cutting equipment. This innovative device will be especially suitable for industrial laser cutting systems that require frequent adjustments to the optical path and replacement of lens assemblies, meeting the stringent requirements of modern laser processing equipment for efficient maintenance and precise adjustment. Summary of the Invention

[0004] To address the shortcomings of the aforementioned crescent wrench, such as poor versatility and flexibility, inability to adjust, high cost, and inconvenience in operation, this utility model provides a round nut assembly and disassembly device that is highly flexible, easy to adjust, and convenient to operate. Designed to meet the laser head adjustment requirements of laser cutting machines, this device maintains versatility while achieving micron-level adjustment accuracy through precision thread engagement, thus meeting the stringent positional accuracy requirements of laser processing equipment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A round nut adjustment device for a laser head of a laser cutting machine includes a force-applying rod, a column, an adjustable column, locking teeth, and a limiting nut; the column is welded to the end of the force-applying rod, and the adjustable column is movably mounted on the rod body. The adjustable column is also threadedly connected to the limiting nut, which fixes the adjustable column to the force-applying rod; locking teeth are respectively provided at the ends of the column and the adjustable column on opposite sides.

[0007] The adjustable column is mounted on the force-applying rod, with a clearance fit between them. To remove the round nut, loosen the limit nut, move the adjustable column until the distance between the adjustable column and the main column is greater than the round nut to be removed, then remove the anti-loosening washer of the nut to be removed, and engage the locking teeth of the column into the notch on one side of the round nut. Then slide the adjustable column until the locking teeth at the end of the adjustable column engage into the notch of the round nut on the opposite side of the column. Then tighten the limit nut. At this point, the round nut to be removed is stably restrained between the column and the adjustable column. Then, rotate the force-applying rod to remove the round nut. In laser head maintenance scenarios, this device can achieve precise micro-adjustment of the laser head round nut. In conjunction with laser optical path calibration requirements, the adjustment accuracy can reach ±0.01mm, meeting the strict requirements of laser cutting processes for the focal point position. Conversely, by first locking the round nut and then rotating the force-applying rod, the round nut can be installed into the equipment. Then, the anti-loosening washer can be installed to complete the installation of the round nut.

[0008] Furthermore, the locking teeth are welded to the upright or adjustable upright. This welded connection makes the structure more robust and durable, preventing the locking teeth from loosening or falling off during use. It also simplifies device operation, eliminating the need for repeated adjustments to the locking teeth position, thus improving disassembly and installation efficiency and safety, and enhancing its practicality and promotional value.

[0009] Furthermore, a threaded post is fixedly provided at one end of the locking tooth; both the upright and the adjustable upright are provided with threaded holes corresponding to the threaded posts, and the locking tooth is connected by engaging the threaded post with the threaded hole. The locking tooth achieves a detachable connection by screwing the threaded post into the threaded hole, and subsequent repair and replacement are possible if the locking tooth is damaged. This improvement makes the locking tooth firmly installed and easy to replace, while ensuring stable force and convenient operation during disassembly and assembly, thus enhancing the flexibility and practicality of the device.

[0010] Furthermore, the locking teeth are rectangular. Rectangular teeth better match the rectangular notches on the round nut, improving the stability and force distribution of the engagement, making disassembly and installation more secure, reliable, and easier.

[0011] Furthermore, the column, adjustable column, and clamping teeth are all made of cast iron alloy. Considering the high-temperature characteristics of the laser equipment's operating environment, the cast iron alloy is preferably a high-temperature resistant type and undergoes a special heat treatment process to ensure structural stability and wear resistance within the laser equipment's operating temperature range. The column, adjustable column, and clamping teeth can be made of wear-resistant materials, such as high-hardness metal alloys, ceramics, or polymer composite materials. Since cast iron alloys among high-hardness metal alloys have good strength, wear resistance, and cost advantages, they can meet the usage requirements of most industrial scenarios and are easy to process and maintain; therefore, cast iron alloys are the preferred material.

[0012] Furthermore, the outer periphery of the retaining teeth is fitted with an anti-slip silicone sleeve. The sleeve and silicone sleeve cooperate to increase the friction when the retaining teeth mate with the notch of the round nut, which can effectively prevent the retaining teeth from slipping during disassembly.

[0013] Furthermore, the force-applying rod is rectangular; the adjustable column includes a movable ring and a fixed rod, wherein the movable ring is mounted on the force-applying rod with a clearance fit, and a limiting nut is threaded to the side of the movable ring, while the fixed rod is connected to the bottom of the movable ring at a position corresponding to the column. The movable ring is fitted onto the force-applying rod with a clearance fit and locked in place by the limiting nut, and the fixed rod corresponds to the column, facilitating the limiting of the round nut; this structure makes the movement of the adjustable column on the force-applying rod more stable and smooth, and easy to adjust, improving the applicability and ease of use of the device.

[0014] Furthermore, the limiting nut is a hand-tightening nut. Hand-tightening nuts are convenient to operate.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. This utility model has a simple structure and is easy to operate. The size can be adjusted by the adjustable column and the limiting nut, making it suitable for round nuts of different specifications and improving its versatility. The device has locking teeth on both sides, which can firmly lock into the notch of the round nut, with uniform force distribution and less slippage, making disassembly and assembly safer and more efficient. Compared with the traditional crescent wrench, it reduces the number of tools, lowers the cost, and is easy to carry and manage. It is suitable for a variety of maintenance and installation occasions, and is especially suitable for the daily maintenance and optical path calibration of laser cutting equipment, significantly improving the maintenance efficiency of laser equipment.

[0017] 2. This utility model uses welding or threaded connection of the locking teeth. Welding improves the structural robustness, while threaded connection facilitates the replacement of the locking teeth. The locking teeth adopt a rectangular tooth design, which can enhance the matching stability with the round nut notch, and the cast iron alloy material is selected to balance strength and wear resistance. The silicone anti-slip sleeve added to the locking teeth prevents slippage, making the overall structure safer, more stable and durable, and the operation more efficient and reliable.

[0018] 3. This utility model uses an adjustable column with a movable ring and a fixed rod structure, which is installed on a rectangular force-adding rod with a gap. Combined with a hand-tightened limit nut, it can quickly lock and adjust, making the device more adaptable to different round nut sizes and more flexible and convenient to operate. The overall structure is stable and reliable, and while facilitating adjustment, it improves disassembly and installation efficiency. This design takes into account the special requirements of the laser equipment maintenance environment, including anti-static and dust-free operation characteristics, to ensure safe use in laser processing workshops.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: A round nut adjustment device for the laser head of a laser cutting machine, including a force-applying rod 1, a column 2, an adjustable column 3, a locking tooth 4, and a limiting nut 5; the column 2 is welded to the end of the force-applying rod 1, and the adjustable column 3 is movably mounted on the rod body. The adjustable column 3 is also threadedly connected to the limiting nut 5, and the limiting nut 5 fixes the adjustable column 3 to the force-applying rod 1; the locking teeth 4 are respectively provided at the ends of the column 2 and the adjustable column 3 on opposite sides.

[0025] The adjustable column 3 is mounted on the force-applying rod 1, with a clearance fit between them. To remove the round nut, loosen the limiting nut 5, move the adjustable column 3 so that the distance between the adjustable column 3 and the column 2 is greater than the round nut to be removed, then remove the anti-loosening washer of the nut to be removed, and insert the locking teeth 4 of the column 2 into the notch on one side of the round nut. Then slide the adjustable column 3 so that the locking teeth 4 at the end of the adjustable column 3 engage with the notch of the round nut on the opposite side of the column 2. Then tighten the limiting nut 5. At this point, the round nut to be removed is stably restricted between the column 2 and the adjustable column 3. Then, rotate the force-applying rod 1 to remove the round nut. In laser head maintenance scenarios, this device can achieve precise micro-adjustment of the laser head round nut. In conjunction with the laser optical path calibration requirements, the adjustment accuracy can reach ±0.01mm, meeting the strict requirements of the laser cutting process for the focal point position. Conversely, by first locking the round nut and then rotating the force-applying rod 1, the round nut can be installed into the equipment. Then, the anti-loosening washer can be installed to complete the installation of the round nut.

[0026] Example 2: Unlike Example 1, one end of the locking tooth 4 is fixedly provided with a threaded post 41; both the column 2 and the adjustable column 3 are provided with threaded holes 6 corresponding to the threaded posts 41. The locking tooth 4 is connected by engaging the threaded post 41 with the threaded hole 6. The locking tooth 4 achieves a detachable connection by screwing the threaded post 41 into the threaded hole 6, allowing for subsequent repair and replacement if the locking tooth 4 is damaged. This improvement makes the locking tooth 4 securely installed and easy to replace, while ensuring stable force and convenient operation during assembly and disassembly, thus enhancing the flexibility and practicality of the device.

[0027] The force-applying rod 1 is rectangular; the adjustable column 3 includes a movable ring 31 and a fixed rod 32. The movable ring 31 is installed on the force-applying rod 1 with a clearance fit, and a limiting nut 5 is threaded to the side of the movable ring 31. The fixed rod 32 is connected to the bottom of the movable ring 31 at a position corresponding to the column 2. The movable ring 31 is fitted onto the force-applying rod with a clearance fit and locked in place by the limiting nut 5. The fixed rod 32 corresponds to the column 2, facilitating the limiting of the round nut. This structure makes the movement of the adjustable column 3 on the force-applying rod 1 more stable and smooth, and the adjustment is convenient, improving the applicability and ease of use of the device.

[0028] Example 3: The difference from Example 2 is that the locking teeth 4 are rectangular teeth. Rectangular teeth can better match the rectangular notches on the round nut, improving the stability and force-bearing effect of the engagement, making the disassembly and installation process more secure and reliable, and easier to operate.

[0029] The column 2, adjustable column 3, and clamping teeth 4 are all made of cast iron alloy. Considering the high-temperature characteristics of the laser equipment's working environment, the cast iron alloy is preferably a high-temperature resistant type and undergoes a special heat treatment process to ensure structural stability and wear resistance within the laser equipment's operating temperature range. The column 2, adjustable column 3, and clamping teeth 4 can be made of wear-resistant materials, such as high-hardness metal alloys, ceramics, or polymer composite materials. Since cast iron alloys among high-hardness metal alloys have good strength, wear resistance, and cost advantages, they can meet the usage requirements of most industrial scenarios and are easy to process and maintain; therefore, cast iron alloys are the preferred material.

[0030] The outer periphery of the retaining tooth 4 is fitted with an anti-slip silicone sleeve. The sleeve and silicone sleeve cooperate to increase the friction when the retaining tooth 4 engages with the notch of the round nut, which can effectively prevent the retaining tooth 4 from slipping during disassembly.

[0031] The limiting nut 5 is a hand-tightening nut. Hand-tightening nuts are convenient to operate.

[0032] Example 4: The difference from Example 1 is that the locking teeth 4 are welded to the column 2 or the adjustable column 3. Welding the locking teeth 4 to the column 2 or the adjustable column 3 makes the structure more robust and durable, preventing the locking teeth 4 from loosening or falling off during use. Furthermore, the device is easier to operate, eliminating the need for repeated adjustments to the position of the locking teeth 4, thus improving disassembly and installation efficiency and safety, and possessing greater practicality and promotional value.
