Description

Technical Field

[0001] This utility model relates to the field of laser installation technology, and in particular to a connection and fixing structure for an integral laser housing. Background Technology

[0002] As precision optical devices, the structural stability and ease of installation of lasers have a significant impact on overall performance and maintenance. In existing technologies, to improve the overall rigidity and on-site installation efficiency of lasers, an integrated housing structure is typically used. This involves assembling the core components of the laser inside the housing before shipment and performing optical and mechanical calibrations, thereby reducing on-site commissioning time and lowering installation costs.

[0003] For example, Chinese patent document CN209929667U discloses an "integrated housing for housing a carbon dioxide laser." This structure includes components such as a cylinder, a support plate, a bracket, and fastening devices, enabling the laser and housing to be assembled and calibrated as a whole in the factory, thus achieving integrated transportation and installation. However, in actual installation, positioning, and use, this type of integrated housing structure typically relies on pre-set fixing holes on the housing to connect with the mounting plane of the frame. Specifically, during installation, the holes on the housing must be precisely aligned with the corresponding holes on the mounting plane of the frame, and then secured with bolts or screws. Although this method is structurally simple, it often leads to installation difficulties due to mismatched holes when changing the laser's mounting position or adapting to different laser specifications, limiting the flexible deployment of the laser in different application scenarios.

[0004] Therefore, the existing integrated laser housing still needs improvement in terms of structural design and installation methods. There is an urgent need for a housing structure and installation method with higher installation adaptability that can achieve fast and reliable fixation without relying on preset hole positions, so as to solve the installation difficulties caused by hole mismatch in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a connection and fixing structure for an integral laser housing, thereby solving at least one deficiency in the prior art.

[0006] This utility model provides a connection and fixing structure for an integral laser housing, including a cylindrical body. The cylindrical body has flanges on both sides for cooperating with a mounting plane. The flanges are arranged along the length direction of the cylindrical body. The flanges are fixed to the mounting plane by a pressure block. The pressure block is detachably connected to the mounting plane by a fastening device. The clamping force of the pressure block and the mounting plane on the flanges is adjusted by the fastening device to limit the relative displacement of the cylindrical body.

[0007] Preferably, the flange has a positioning part along its length on the side opposite to the mounting plane, and the pressure block has a mating part for engaging with the positioning part.

[0008] Preferably, the positioning part has a protruding or recessed structure.

[0009] Preferably, an installation gap is provided between the pressure block and the mounting plane, and a pad is provided on the side of the pressure block away from the flange.

[0010] Preferably, the pad and the pressure block are integrally formed.

[0011] Preferably, the pressure block has a notch for laterally limiting the flange, the height of the notch is less than the height of the flange, and the notch is provided through the flange along its length.

[0012] Preferably, the mating surfaces of the flange and / or the pressure block are provided with teeth.

[0013] Preferably, the above-mentioned connection and fixing structure further includes a support plate disposed at the bottom of the cylinder, the upper surface of the support plate serving as the mounting plane, the support plate being provided with at least two adjusting grooves extending along the length direction of the flange, the adjusting grooves being connected to the pressure block through the fastening device; or, the support plate being provided with at least two rows of mounting holes, the mounting holes being arranged at intervals along the length direction of the flange, the mounting holes being connected to the pressure block through the fastening device.

The fastening components are used to support and fix the laser. The support plate slides with the cylinder along the length direction of the cylinder. The support plate and the cylinder can be fixed to each other by a fixing device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a connection and fixing structure for an integral laser housing.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0020] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0022] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0023] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0024] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0025] Example like Figures 1-8 As shown, a connection and fixing structure for an integral laser housing includes a cylindrical body 1 and a clamping block 2. Flanges 11 for mating with mounting planes are provided on both sides of the cylindrical body 1, and the flanges 11 are arranged along the length of the cylindrical body 1. Each flange 11 is fixedly mounted to the mounting plane via the clamping block 2. The clamping block 2 is detachably connected to the mounting plane via a fastening device 3. The clamping force of the clamping block 2 and the mounting plane on the flanges 11 is adjusted by the fastening device 3 to limit the relative displacement of the cylindrical body 1.

[0026] This solution uses a pressure block 2 to be fixedly connected to the mounting plane via a fastening device 3. The pressure block 2 presses the corresponding side flange 11 of the cylinder 1 onto the mounting plane. By adjusting the clamping force of the pressure block 2 and the mounting plane on the flange 11 through the pre-tightening fastening device 3, the relative displacement of the cylinder 1 is restricted, thereby achieving fixed installation between the cylinder 1 and the mounting plane. This can solve the installation difficulty problem caused by the mismatch between the hole positions on the outer shell and the mounting hole positions on the existing mounting plane in the prior art.

[0027] The pressure block 2 can be installed according to the position of the mounting holes on the existing frame mounting plane. Its position relative to the flange 11 is infinitely adjustable, unaffected by the pre-set hole spacing on the flange 11, making adjustment convenient and providing good adaptability to various working conditions. When changing the laser application scenario or replacing a laser of a different specification in the original application scenario, a pressure block 2 of the appropriate size can be replaced according to the distance between the flange 11 of the housing and the mounting hole positions on the mounting plane, improving the laser installation adaptability. Compared to re-drilling holes in the laser housing or mounting plane, this method is lower in cost and avoids damage.

[0028] In an optional embodiment, the mating surfaces of the flange 11 and / or the pressure block 2 are further roughened, for example, by providing serrations, to increase the contact friction between the flange 11 and the pressure block 2 and / or between the flange 11 and the mounting surface, thereby improving the limiting effect. By tightening the fastening device 3, the normal pressure of the pressure block 2 on the flange 11 and the mounting surface is increased, and the flange 11 is restricted from shifting due to the greater friction.

[0029] In an optional embodiment, multiple pressure blocks 2 are preferably arranged at intervals along the length of each flange 11, and each pressure block 2 is provided with a corresponding connecting hole in the middle, and each pressure block 2 is used to connect with a fixed mounting hole on the mounting plane.

[0030] Alternatively, as another possible implementation, a pressure block 2 with a relatively long length can be provided on each flange 11, so that the pressure block 2 is continuously provided along the length direction of the flange 11. Correspondingly, it is preferable to connect the pressure block 2 to the corresponding mounting hole on the mounting plane through at least two fastening devices 3. The multi-point mechanical connection can better restrict the rotational freedom of the pressure block 2 on the plane, making the installation more reliable. Compared with the method of only setting one pressure block 2 and relying solely on the surface roughness of the material for positioning, it is more conducive to fixing the shell.

[0031] In one or more embodiments, the pressure block 2 preferably has a small square structure with a connecting hole in the middle; for example... Figure 4 , Figure 5 As shown, a positioning part 111 is provided along the length direction on the side of the flange 11 facing away from the mounting plane, and a mating part 21 is provided on the pressure block 2 for engaging with the positioning part 111. The positioning part 111 and the mating part 21 engage with each other to achieve lateral positioning of the outer shell.

[0032] In an optional embodiment, the positioning part 111 is preferably configured as a protruding structure, extending along the length direction of the flange 11; correspondingly, the mating part 21 is configured as a groove structure, extending through the length direction, which is simple in structure and facilitates continuous adjustment along the longitudinal direction. As another possible embodiment, the positioning part 111 may also adopt a groove structure, and the mating part 21 may adopt a protruding structure.

[0033] In one or more embodiments, to achieve vertical alignment of the pressure block 2 with the mounting plane hole and improve installation efficiency, such as... Figure 4 , Figure 6 , Figure 8 As shown, an installation gap 6 is provided between the pressure block 2 and the mounting plane, making the upper surface of the pressure block 2 parallel to the mounting plane. A pad 22 can be provided on the side of the pressure block 2 away from the flange 11 for height support. During installation, by increasing the preload between the fastening device 3 and the mounting plane, the middle of the pressure block 2 can be slightly deformed by downward concavity, improving the clamping and fixing ability of the flange 11. The pad 22 can be set separately and independently, or it can be integrally formed with the pressure block 2.

[0034] In one or more implementations, such as Figure 4 , Figure 7 As shown, the pressure block 2 has a notch 23 for lateral positioning with the flange 11. The notch 23 is inverted L-shaped, and its height is less than that of the flange 11. The notch 23 extends through the flange 11. The notch 23 can be inserted into the outer contour of the flange 11 or fitted with the fitting part 21. The sidewall of the notch 23 is spaced a certain distance from the outer contour of the flange 11 for over-limit positioning. Under certain working conditions, when the external vibration is too great and the positioning part 111 on the flange 11 is damaged, it can be moved laterally along the notch 23 to the sidewall of the notch 23, that is, the notch is limited by the notch itself to ensure safe use.

[0035] In one or more implementations, such as Figures 2-4 As shown, the above-mentioned connection and fixing structure also includes a support plate 4. The support plate 4 is set at the bottom of the cylinder 1. The support plate 4 can be the mounting plane of the frame, or it can be used as a transition plate between the cylinder 1 and the mounting plane of the frame. In this case, the mounting plane of the cylinder 1 is the upper surface of the support plate 4. By replacing the support plate 4 or drilling holes in the support plate 4, the cylinder 1 can be fixedly installed with the frame without damaging the cylinder itself.

[0036] In an optional embodiment, at least two adjusting grooves (not shown in the figure) extending along the length of the flange 11 can be provided on the support plate 4. The adjusting grooves and the pressure block 2 are fixedly connected by the fastening device 3, avoiding the problem of the outer shell needing to be adapted to a specific hole spacing and improving the installation adaptability of the outer shell. The adjusting groove can be set as an elongated hole with a countersunk groove at the bottom to hide the nut of the fastening device 3 and make the bottom surface flat; or, the adjusting groove can also be set as a T-slot, and the fastening device 3 uses a T-bolt to cooperate with the adjusting groove.

[0037] In an optional embodiment, at least two rows of mounting holes (not shown in the figure) may be provided on the support plate 4. The mounting holes are arranged at intervals along the length of the flange 11. The mounting holes at fixed positions are connected to the pressure block 2 by fastening devices 3. At least two mounting holes are respectively fixedly connected to the flange 11 by a pressure block 2. The positioning holes are preferably set as blind holes with internal threads. The fastening device 3 can be a bolt, screw, or screw and nut assembly, etc., which can be adapted to the mounting holes on the mounting surface for fixation. It is not limited to the above examples.

[0038] Furthermore, in alternative implementations, such as Figure 3 , Figure 4 As shown, the upper surface of the support plate 4 has a protrusion 41, and the bottom of the cylinder 1 has a recess. The protrusion 41 and the recess are in a convex-concave fit, which facilitates the rapid positioning of the cylinder 1, realizes lateral limitation, and helps to ensure the working quality of the beam.

[0039] In one or more implementations, such as Figures 2-4 As shown, the aforementioned connection and fixing structure also includes a support plate 5. The support plate 5 is disposed inside the cylinder 1 for installing fastening components. The fastening components support and fix the laser. The support plate 5 slides along the length of the cylinder 1 and is slidably engaged with the cylinder 1. The support plate 5 and the cylinder 1 can be fixed to each other by a fixing device. In use, the laser is installed on the support plate 5 in the factory using the fastening components, and the laser position is adjusted to ensure beam quality, so as to avoid relative sliding between the laser and the support plate 5 during transportation or later use. Then, the support plate 5 and the laser are moved together from one end of the cylinder 1 into the cylinder 1, and the support plate 5 and the cylinder 1 are fixed to each other by the fixing device, and then transported to the installation site. At the installation site, only the integrated outer shell and the laser need to be installed into the machine equipment, without the need for on-site adjustment by a special technician, which is simple and convenient, and reduces installation costs.

[0040] The fastening assembly includes a support and a fastening device 3. The support is used to support the laser, and the fastening device 3 is used to fix the laser to the support. The fastening assemblies are spaced apart along the length of the cylinder 1, which is prior art and will not be described in detail. The fixing device can be bolts. The bottom of the cylinder 1 has connecting holes adapted to the bolts, and the bolts can pass through the connecting holes and be fixedly engaged with the support plate 5. Further, as... Figures 2-4 As shown, a guide rail 12 is provided inside the cylinder 1 along the length of the cylinder 1. The guide rail 12 is located on the lower side wall of the cylinder 1, and a sliding groove 51 that cooperates with the guide rail 12 is provided on the support plate 5.

[0041] Furthermore, in one or more embodiments, such as Figure 1 As shown, at least one end of the cylinder 1 is connected to an end cap, and at least one end cap is provided with a through hole for the laser beam output by the laser to pass through. At least one end cap on the cylinder 1 is detachably connected to the cylinder 1.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
