Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular, it relates to an adjustable beam mounting structure. Background Technology

[0002] The application of laser cutting machines (laser tube cutting machines) has developed rapidly in the domestic market in recent years, especially in the field of sheet metal cutting and processing. They have advantages such as high cutting accuracy, fast cutting speed, adaptability to various complex graphics, automatic layout, smooth cut, and low processing cost, and have well replaced punching machines, flame cutting and plasma cutting equipment.

[0003] When lasers cut sheet metal parts, the sheet metal parts are generally stationary while the laser cutting head cuts them. Therefore, the laser cutting head needs to be able to move in two directions. This requires a mechanism on the laser cutting machine that can move the laser cutting head in two mutually perpendicular horizontal directions. Generally, a crossbeam structure is installed on the laser cutting machine. The crossbeam structure can move horizontally along the X-axis of the machine, and the laser cutting head moves horizontally along the Y-axis on the crossbeam. The stability of the connection structure between the crossbeam and the laser cutting machine is crucial. For example, Chinese utility model patent CN221494685U discloses a laser cutter crossbeam base fixing device, including a frame. A processing table is fixedly connected to the top of the frame. Housings are slidably connected to both sides of the top of the frame. A fixing plate is fixedly connected to the inner cavity of the housing. A dual-axis motor is fixedly connected to the surface of the fixing plate. Threaded rods are fixedly connected to both sides of the dual-axis motor. The side of the threaded rod away from the dual-axis motor is movably connected to the inner wall of the housing through a bearing. The above-mentioned utility model can effectively solve the problem that traditional laser cutters do not have the function of quickly disassembling the crossbeam base during use, resulting in poor flexibility during installation, inability to improve subsequent maintenance efficiency, and thus reduced performance. This fixing device can achieve convenient installation and disassembly, ensuring the convenience of the device during use and improving the effectiveness of subsequent maintenance.

[0004] However, the above-mentioned beam structure still has the following drawbacks: poor connection between the beam and the base, which leads to a decrease in the connection accuracy between the beam and the base after long-term operation or high-speed displacement of the beam. This can result in excessive laser cutting errors, requiring recalibration of the connection accuracy, or even jamming of the entire beam displacement mechanism, damage to the laser detection head, and poor stability of the entire laser cutting mechanism.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design an adjustable beam mounting structure. Utility Model Content

[0021] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0022] Techniques, methods, and systems known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and systems should be considered part of this utility model specification.

[0023] Example 1: As Figures 1 to 4 The illustration shows only one embodiment of this utility model. An adjustable crossbeam mounting structure includes a base 2 mounted on a frame plate 3 of a laser cutting machine and a crossbeam 1 connected to the base 2. The frame plate 3 is provided with a first guide rail 31 for facilitating the sliding of the base 2. The base 2 is provided with a slider 21 for connecting to the guide rail 31 and a pressure block 22 disposed on the side of the slider 21. The crossbeam 1 is provided with a first hole 11, and the base 2 is provided with a second hole 23 for aligning with the first hole 11. The crossbeam 1 is also provided with a pin hole 12 and an anti-loosening pin for inserting into the pin hole 12.

[0024] In this utility model, the bed structure of the laser cutting machine tool includes two frame plates on both sides and a connecting plate 32 (connecting square tube) for connecting the two frame plates. The crossbeam mounting structure is set on the upper side of the two frame plates. The crossbeam mounting structure includes a crossbeam 1 and a base 2. The two bases 2 are respectively set at the two ends of the crossbeam 1 and the connection points of the frame plates 3 on both sides. The crossbeam 1 is set roughly perpendicular to the frame plates 3. The crossbeam 1 slides on the frame plates along the X-axis, and the laser cutting head on the crossbeam 1 slides on the crossbeam 1 along the Y-axis. In this way, the laser cutting head cuts the sheet metal parts on the connecting square tube of the laser cutting machine tool (in fact, the connecting square tube is also equipped with a heat insulation grid plate for placing the sheet metal parts). That is, the area between the two frame plates 3 is the laser cutting area.

[0025] Of course, the frame plate 3 is provided with a first guide rail 31 for facilitating the sliding of the base 2, and the crossbeam 1 is provided with a second guide rail 14 for facilitating the sliding of the laser cutting head.

[0026] A slider 21 for connecting with the guide rail 31 and a pressing block 22 arranged on the side of the slider 21 are provided on the base 2. A slider groove is provided on the lower side of the base 2. At least a part of the slider 21 and the pressing block 22 is located in the slider groove. The width of the slider groove is wider than that of the slider 21. The slider 21 is connected to the first guide rail 31 in a C-shaped semi-surrounding manner, and then the slider 21 is inserted into the slider groove. Then, the pressing block 22 is inserted into the slider groove on one side of the slider 21. The sum of the widths of the slider 21 and the pressing block 22 is slightly larger than the width of the slider groove, so that the insertion of the pressing block 22 can tightly squeeze the slider 21 against the edge of the slider groove, completing the tensioning connection, thus completing the preliminary connection between the frame plate 3 and the base 2.

[0027] Then, a first hole 11 is provided on the cross beam 1, and a second hole 23 for aligning with the first hole 11 is provided on the base 2. In fact, multiple groups of second holes 23 are provided on the base 2. After the cross beam 1 is placed on the base 2 and the cross beam 1 and the base 2 are placed vertically, there must be a group of second holes 23 aligned with the first hole 11 on the cross beam 1.

[0028] After the first hole 11 and the second hole 23 are aligned, the first perpendicularity detection is performed on the cross beam and the frame plate to ensure that the maximum inclination amount between the cross beam and the frame plate does not exceed 0.01 mm, then the perpendicularity detection is qualified. At this time, the connecting bolts can be inserted into the first hole 11 and the second hole 23, and the connecting bolts connect the first hole and the second hole, completing the preliminary connection between the base 2 and the cross beam 1.

[0029] During this connection process, in order to avoid the cross beam having errors again, the second perpendicularity detection is performed on the cross beam and the frame plate to ensure that the maximum inclination amount between the cross beam and the frame plate does not exceed 0.01 mm, then the perpendicularity detection is qualified. At this time, it is determined that the preliminary connection between the base 2 and the cross beam 1 does not damage the installation accuracy of the cross beam. Then, further installation is carried out. A drill bit is used to drill downward at the pin hole on the cross beam 1 until the base 2 is penetrated. Then, a pin is inserted into the penetrated pin hole, and the pin passes through the pin hole and is inserted into another pin hole penetrated on the base 2 to perform the second-step connection between the base 2 and the cross beam 1.

[0030] After the second-step connection between the base 2 and the cross beam 1, the connecting bolts at all connection points can be tightened to complete the final connection among the cross beam 1, the base 2, and the frame plate 3.

[0031] Specifically, the steps for installing an adjustable cross beam installation structure of the present utility model are as follows: First, connect the slider on the base to the first guide rail on the frame plate, and use a pressure block to press the side of the slider to complete the initial connection between the base and the frame plate. Then, place the crossbeam on the base, aligning the first hole and the second hole on the crossbeam to complete the initial alignment between the base and the crossbeam. Next, perform the first perpendicularity test on the crossbeam and the frame plate. After the perpendicularity test is qualified, insert the connecting bolts through the first and second holes in sequence to complete the initial connection between the base and the crossbeam. Then, perform the second perpendicularity test on the crossbeam and the frame plate. After the perpendicularity test is qualified, drill holes downward through the base at the pin holes of the crossbeam, and insert pins into the pin holes until they reach the base to complete the final connection between the crossbeam, the base, and the frame plate.

[0032] Example 2, still as Figures 1 to 4 As shown, this is only one embodiment of the present invention. Based on the first embodiment, in the adjustable beam mounting structure of the present invention, when the pressure block is used to press the side of the slider to complete the initial connection between the base and the frame plate, the pressure block 22 is fastened to the base 2 by bolts. However, there are no bolts connecting the slider 21 and the base 2. The slider 21 and the base 2 are only connected by a pressing type. Until the pin is inserted into the pin hole and reaches the base, in the final connection of the beam, the base and the frame plate, one step is to complete the connection between the slider 21 and the base 2 by bolts.

[0033] Similarly, the connecting bolts are inserted sequentially through the first hole 11 and the second hole 23. Of course, both the first hole 11 and the second hole 23 are threaded holes. When the connecting bolts are inserted to complete the initial connection between the base and the crossbeam, the connecting bolts are not tightened. They are only inserted through the first hole 11 and the second hole 23. That is, after passing through the first hole 11, the lower end of the connecting bolt is just inserted a little bit into the second hole 23 to ensure that the crossbeam 1 and the base 2 will not be horizontally displaced. After the pin is inserted into the pin hole and into the base, the final connection between the crossbeam, the base and the frame plate is completed by tightening the connecting bolts to complete the connection between the crossbeam 1 and the base 2.

[0034] Furthermore, when drilling downwards at the pin hole on the crossbeam 1, it is necessary to drill straight through the base 2 and insert a portion into the slider 21. When inserting the pin into the pin hole, it will pass through the pin hole 12 and another pin hole drilled on the base 2 until it is inserted into the slider 21.

[0035] In other words, completing the final connection of the crossbeam, base and frame plate actually includes three connections: connecting the slider 21 to the base 2 with bolts, connecting the crossbeam 1 to the base 2 with tightening the connecting bolts, and inserting a pin through the pin hole 12 and another pin hole drilled on the base 2 until it is inserted into the slider 21.

[0036] In addition, the slider 21 is a long condition. Although the length of the slider 21 is not as long as the first guide rail, the slider 21 is also a long strip. Generally, the length of the slider 21 is about 20cm. Ideally, the slider 21 is provided with a third hole that is aligned with the second hole 23. When tightening the connecting bolts, the crossbeam, the base and the frame plate can be connected.

[0037] Example 3, still as Figures 1 to 4 As shown, this is only one embodiment of the present utility model. Based on any of the above embodiments, in the adjustable beam installation structure of the present utility model, the number of frame plates 3 is two, and a connecting plate 32 is provided between the two frame plates 3. The heat insulation grid plate on the connecting plate 32 is provided with a correction block for correcting the verticality of the beam 1.

[0038] The calibration block is a rectangular block with a width roughly equal to the distance between the two frame plates. When one side of the calibration block is aligned with frame plate 3, the perpendicular side can be used to check the verticality of the crossbeam 1. After the check is complete, the calibration block can be removed. The correction block can be marble or other high-strength rigid components.

[0039] Of course, if you find the calibration block too troublesome, you can also directly use a verticality detection device to detect the verticality between the beam 1 and the frame plate 3.

[0040] Example 4, still as Figures 1 to 4 As shown, this is only one embodiment of the present utility model. Based on any of the above embodiments, in an adjustable beam mounting structure of the present utility model, a slide 13 is provided on the beam 1, and the laser cutting head is installed on the slide 13. A second guide rail 14 is provided on the beam 1 to facilitate the sliding of the slide 13. The second guide rail 14 is perpendicular to the first guide rail 31.

[0041] In fact, there are two second guide rails 14, one of which is located in... In addition, since the slide 13 slides on the crossbeam 1 and the laser cutting head is inevitably located on the side of the crossbeam 1, in order to ensure the stable connection between the slide 13 and the crossbeam 1, there are two second guide rails 14, one located on the upper side of the crossbeam 1 and the other located on the side of the crossbeam 1 near the laser cutting head. At least two sets of slide blocks are also provided on the slide 13 to be connected to the two second guide rails 14 respectively.

[0042] The base 2 is provided with a spark-proof plate 24 at its end. In fact, the crossbeam 1 is displaced on the frame plate 3. By default, the laser cutting head is located in front of the crossbeam 1. Therefore, the second guide rail is located on the front side of the crossbeam 1. The end of the base 2 near the front of the crossbeam 1 is provided with a spark-proof plate 24. This is to prevent the high-temperature sparks from cutting sheet metal parts after the laser cutting head moves to the end of the crossbeam 1 and gets too close to the base 2, which could cause the base 2 to deform.

[0043] In addition, a protective side plate 26 is provided on the side of the base 2. The protective side plate 26 is provided on the side of the base 2 near the slide 13, which is also to prevent the laser cutting head and the slide 13 from colliding with the side of the base 2.

[0044] Of course, the slide 13 is provided with a first drive motor 15, and the base 2 is provided with a second drive motor 25.

[0045] Furthermore, the pressure block 22 has an inclined surface 221 on the side away from the slider 21.

[0046] Finally, the crossbeam 1 is a hollow component, making the entire crossbeam 1 lighter. This not only does not affect the sliding speed of the laser cutting head, but also allows the crossbeam 1 to be wider. Compared to the ordinary crossbeam design, the wider crossbeam 1 also improves the stability of the crossbeam 1. This stability includes the stability of the crossbeam 1 itself (the crossbeam 1 itself is not easily deformed), the stability of the crossbeam 1's displacement along the frame plate (the contact surface between the crossbeam 1 and the base 2 on the frame plate is larger), and the stability of the connection between the slide and the crossbeam 1 (the laser cutting head is set on the side in front of the crossbeam 1 in the direction of displacement so that it can cut the sheet metal parts under the crossbeam 1. The weight of the laser cutting head will inevitably deviate from the crossbeam and be located in front of the crossbeam in the direction of displacement. The wider crossbeam 1 allows for a larger contact surface between the slide 2 and the crossbeam 1, resulting in a more stable connection).

[0047] Furthermore, since the crossbeam 1 is hollow, in order to ensure the strength of the entire crossbeam 1 and prevent it from being easily deformed or broken, support bars 14, i.e., reinforcing ribs, need to be installed in the hollow cavity of the crossbeam 1. In order to further enhance the structural stability of the crossbeam 1, a widening area is provided on the side of the crossbeam 1 away from the second and second guide rails 14 (i.e., the side away from the laser cutting head). The widening area has the same thickness as the crossbeam 1 and is used to widen the crossbeam 1. Moreover, the widening area is also hollow and does not require a support structure inside the cavity. Of course, there is at least one widening area to provide a stable structure for the crossbeam 1.

[0048] The crossbeam 1 is a one-piece molded aerospace aluminum component. Aerospace aluminum structures are lightweight and high-strength, making them well-suited for use in the crossbeam 1 structure. Furthermore, the fact that the crossbeam 1 is a one-piece molded component enhances its structural stability.

[0049] The base 2 is also a one-piece molded steel component.

[0050] This utility model discloses an adjustable crossbeam mounting structure. Its structure is simple; the slider on the base connects to the guide rail on the frame plate with a pressure block for fastening. The first hole on the crossbeam and the second hole on the base are aligned for alignment. Furthermore, the crossbeam has pin holes for installing anti-loosening pins, ensuring high installation accuracy and good structural stability after installation. Example 5: This utility model also explains the installation steps of an adjustable beam mounting structure in all the above embodiments: S1: Connect the slider on the base to the first guide rail on the frame plate, and use the pressure block to press the side of the slider to initially connect the base to the frame plate; S2: Place the crossbeam on the base so that the first hole on the crossbeam is aligned with the second hole; S3: Perform the first verticality test on the crossbeam and the frame plate. After the verticality test is qualified, insert the connecting bolts and pass them through the first and second holes in sequence. S4: Perform a second verticality test on the crossbeam and the frame plate. After the verticality test is qualified, drill holes downward through the base at the pin holes of the crossbeam, insert the pins into the pin holes until they reach the base, and tighten the connecting bolts to complete the final connection between the base and the frame plate.

[0051] The frame plate consists of two plates, and a connecting plate is provided between the two frame plates. The connecting plate is provided with a correction block. During steps S3 and S4, the perpendicularity of the crossbeam to the frame plate is checked using the calibration block.

[0052] This utility model discloses an adjustable crossbeam installation structure. The structure is simple. The slider on the base is fastened to the guide rail on the frame plate by a pressure block. The first hole on the crossbeam and the second hole on the base are aligned for connection. The crossbeam also has pin holes for installing anti-loosening pins, ensuring high installation accuracy and good structural stability after installation.

[0053] This utility model is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model.
