Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser support frame for carbon dioxide lasers and a laser engraving and cutting machine. Background Technology

[0002] Currently, many laser engraving and cutting machines use carbon dioxide lasers as their laser emitters. When installing a carbon dioxide laser, because the outer part is a cylindrical glass tube, it is generally supported by a lifting method. For example, application number CN202321596219.3, invention titled "A Laser Tube Fixing Bracket," states that the bracket not only needs to provide support but also adjustment. Existing fixing brackets can only adjust vertically, not horizontally, meaning they cannot change the horizontal light output direction of the carbon dioxide laser. This makes the installation of carbon dioxide lasers very demanding, requiring very high precision in the fixing bracket's manufacturing, resulting in high costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a laser support frame that can not only adjust the height of a carbon dioxide laser horizontally but also adjust it in the front-back direction. The adjustment operation is convenient and the frame cost is relatively low.

Detailed Implementation

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0024] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 3 As shown.

[0027] Example 1: See Figure 1 , Figure 2A laser support frame 40 includes: a main support body 3 and a movable support body 2. The main support body 3 is provided with fixed ears 7 on its front and rear sides respectively. A height adjustment mechanism is provided between the movable support body 2 and the main support body 3. The height of the movable support body 2 can be adjusted by the height adjustment mechanism. The upper end of the movable support body 2 is provided with a support surface 6 that cooperates with the laser. The fixed ears 7 are provided with connecting grooves 8 in the front and rear directions.

[0028] Compared with existing technical solutions, the main difference in this technical solution is the addition of a front-to-back connecting groove 8 in the fixing ear 7. When the laser support frame 40 is connected to the frame 20 of the laser engraving and cutting machine, a fixing bolt is connected in the connecting groove 8, with the lower end of the fixing bolt passing through the connecting groove 8 and connecting to the connecting hole on the frame 20. At this time, the fixing bolt is not tightened, allowing the laser support frame 40 to be adjusted in the front-to-back direction relative to the frame 20. Then, the carbon dioxide laser 30 is placed on the laser support frames 40 on both sides. Both support frames can be adjusted in height and in the front-to-back direction, thus adjusting the horizontality and collimation of the laser emitted by the carbon dioxide laser 30. This appropriately reduces the assembly requirements and processing accuracy requirements of the laser support frame 40, thereby reducing processing and production costs.

[0029] See Figure 1 , Figure 2 The height adjustment mechanism includes a support column 9 connected to the main support body 3. The upper end of the main support body 3 has a vertical through hole, and the support column 9 is disposed in the through hole. The lower end of the movable support body 2 has an insertion hole that mates with the support column 9. The upper end of the support column 9 extends out of the main support body 3 and is inserted into the insertion hole. The side of the main support body 3 has a mounting hole 31, and an adjusting ring 4 is disposed in the mounting hole 31. The middle part of the support column 9 has an external thread, and the adjusting ring 4 has an internal thread. The support column 9 and the adjusting ring 4 are threadedly connected.

[0030] When adjusting the height, the adjusting ring 4 is rotated through the mounting hole 31. The adjusting ring 4 is threadedly connected to the support column 9. Since the adjusting ring 4 is confined within the mounting hole 31, it cannot move up or down. Therefore, when the adjusting ring 4 is rotated, the support column 9 moves up and down, thereby adjusting the height of the movable support 2. Secondly, the support column 9 may also rotate when the adjusting ring 4 is rotated. To avoid this, when the upper end of the support column 9 is inserted into the movable support 2, the support column 9 and the movable support 2 are connected by a mating or interference fit, making the support column 9 and the movable support 2 a single unit. Since the movable support 2 is connected to the carbon dioxide laser 30 through the support surface 6, the movable support 2 will not rotate along with the support column 9; thus, the rotation of the support column 9 is prevented. The support column 9 can only move up and down.

[0031] Secondly, to facilitate the operation of the adjusting ring 4, friction texture is provided on the side of the adjusting ring 4. The friction texture can be: several protrusions or recesses provided on the side of the adjusting ring 4.

[0032] See Figure 2 The side of the support column 9 is provided with a vertical groove 91, and the inner side of the insertion hole or / and through hole is provided with a protrusion (not shown in the figure) that matches the groove 91. The protrusion is inserted into the groove 91.

[0033] In practical applications, the support column 9 is connected to the insertion hole via a mating or interference fit, requiring very high machining precision for both the support column 9 and the insertion hole, which increases costs. To reduce machining costs, this embodiment uses a groove 91 on the side of the support column 9 and a protrusion on the inner side of the insertion hole or through hole. The rotation of the support column 9 is restricted by the engagement of the protrusion and the groove 91. The vertical width of the protrusion can be very small, or it can extend through the entire insertion hole or through hole.

[0034] Secondly, the fitting precision between the protrusion and the groove 91 can be low or very low. The space inside the groove 91 only needs to be larger than the volume of the protrusion to accommodate it; during adjustment, the protrusion acts to resist the side of the groove 91 and prevent the support column 9 from rotating.

[0035] As a variation of the technology: the side of the support column 9 is provided with a vertical groove 91, the upper end face of the main support body 3 is connected to a limiting ring that is sleeved with the support column 9, and / or the lower end face of the movable support body 2 is connected to a limiting ring that is sleeved with the support column 9, and the inner side of the limiting ring is provided with a protrusion that cooperates with the groove 91.

[0036] Machining a protrusion on the inner surface of the insertion or perforation would be complex; to reduce costs, this embodiment can use a directly connected limiting ring, the inner surface of which has a protrusion. The limiting ring can be relatively thin, formed by casting or forging, which is inexpensive. When the limiting ring is connected to the main support 3 and the movable support 2, it can be connected by bolts, or by bonding, welding, riveting, etc.

[0037] See Figure 2 The side of the support column 9 is provided with a vertical groove 91, and the side of the main support body 3 is connected with a main limiting bolt, the end of which extends into the groove 91; or / and the side of the movable support body 2 is connected with a secondary limiting bolt 12, the end of which extends into the groove 91.

[0038] As another implementation, bolts can be used as protrusions. Specifically, threaded holes are provided on the side of the main support 3 and / or the movable support 2. These threaded holes communicate with through holes or insertion holes. When the support column 9 passes through, the bolt is inserted so that the head of the bolt enters the groove 91. The bolt size can be relatively small.

[0039] See Figure 1 , Figure 2 The main support body 3 is connected to positioning posts 5 on both sides, and the movable support body 2 is provided with guide grooves on both sides that cooperate with the positioning posts 5. The upper end of the positioning post 5 is inserted into the guide groove.

[0040] The lower end of the positioning post 5 can be inserted into the main support body 3. The cooperation between the positioning post 5 and the guide groove ensures that the movable support body 2 will not wobble when moving up and down, and can move stably and linearly. Secondly, to facilitate the connection between the lower end of the positioning post 5 and the main support body 3, a lower fastening bolt 11 is connected to the side of the main support body 3, and the lower fastening bolt 11 abuts against the lower end of the positioning post 5. At the same time, an upper fastening bolt 13 is connected to the side of the movable support body 2, and the upper fastening bolt 13 abuts against the upper end of the positioning post 5. When the height is adjusted and it is necessary to fix the height of the movable support body 2, the positioning post 5 is fixedly connected to the movable support body 2 by the upper fastening bolt 13.

[0041] See Figure 1 , Figure 2 The upper end of the movable support 2 is connected to a flexible strap 1. The two ends of the flexible strap 1 are respectively provided with connecting grooves 8. The upper sides of the movable support 2 are respectively provided with connecting holes. The flexible strap 1 passes through the connecting grooves 8 through the connector 10, inserts into the connecting holes, and connects to the movable support 2.

[0042] The flexible strap 1 can be made of silicone and has a certain degree of elasticity. The flexible strap 1 is used to fix the carbon dioxide laser 30. A connecting groove 8 is provided to adjust the length of the flexible strap 1. The connector 10 can be bolts or the like. Secondly, to avoid rigid collisions between the carbon dioxide laser 30 and the movable support 2, a flexible buffer layer is provided on the side of the support surface 6. The flexible buffer layer can be a plastic pad.

[0043] Example 2: See Figure 3 A laser engraving and cutting machine includes a frame 20, on which a carbon dioxide laser 30 and a laser support frame 40 are mounted. A connector 10 is provided in a connecting groove 8. The frame 20 has a connecting hole. The connector 10 passes through the connecting groove 8, is inserted into the connecting hole, and is fixedly connected to the frame 20. The end of the carbon dioxide laser 30 overlaps in the support surface 6 and abuts against the flexible strap 1.

[0044] When installing the carbon dioxide laser 30, laser brackets are provided on both sides of the frame 20. Then, the two ends of the carbon dioxide laser 30 are respectively attached to the movable support body 2 of the laser bracket. The horizontal collimation of the carbon dioxide laser 30 is adjusted by adjusting the height of the movable support body 2. During adjustment, the height of the movable support body 2 is adjusted by rotating the adjusting ring 4. Next, the front and rear positions of the two laser brackets are adjusted to adjust the front and rear collimation of the carbon dioxide laser 30. During adjustment, the connector 10 in the support surface 6 is loosened, the main support body 3 is moved, and after adjustment, the connector 10 is screwed in. The connector 10 can be a bolt, etc.
