Description

Technical Field

[0001] This utility model relates to a waterproof structure, and more particularly to a waterproof structure for the motion axis of laser processing equipment. Background Technology

[0002] In the field of laser processing equipment, the waterproof protection of motion axes (such as X / Y axes) directly affects the accuracy and lifespan of the equipment. Currently, bellows covers are the mainstream protection method, effectively preventing water mist from spreading. However, existing bellows cover structures do not solve the problem of water leakage at the connection surfaces between the cover and moving parts. Furthermore, while sealant is used to seal the contact surfaces between the bellows cover and the fixed and moving ends, the sealant layer ages and fails after long-term use, and disassembly requires the removal of residual sealant, resulting in high maintenance costs. Additionally, no stepped surfaces are provided to block water flow.

[0003] Furthermore, Chinese patent CN202220426483.1 discloses a guide rail protection device for a laser cutting machine tool. It uses a T-shaped slider quick-release structure to avoid the adhesive layer. However, there is no drainage path, and leaked water may still remain inside the moving shaft, leading to guide rail corrosion.

[0004] Therefore, the core defects of the existing technology are: ① The mounting surface of the bellows cover relies on sealant, which makes maintenance difficult; ② The water leakage path is not designed with a differentiated flow guiding structure for the fixed end and the moving end, and the leaked water flow can easily invade the inside of the moving shaft (such as the guide rail and the grating ruler).

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a waterproof structure for the motion axis of laser processing equipment, making it more valuable for industrial applications. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a waterproof structure for the motion axis of laser processing equipment.

[0007] This utility model discloses a waterproof structure for the motion axis of laser processing equipment, comprising a marble base plate on which a gantry frame is mounted. The marble base plate has marble bosses. An X-axis is distributed on the marble bosses, and a bellows cover X is placed on the X-axis. Fixed ends of the bellows cover X are distributed on both sides of the bellows cover X, and a movable end of the bellows cover X is distributed in the middle of the bellows cover X. A Y-axis is mounted on the upper end of the movable end of the bellows cover X, and a bellows cover Y is placed on the Y-axis. A movable end of the bellows cover Y is located on the inner side of the bellows cover Y, and a fixed end of the bellows cover Y is located on the outer side of the bellows cover Y. The movable end of the bellows cover X is connected to... A sliding plate X is attached, with stepped surfaces distributed at its ends. A movable contact surface is installed on the stepped surfaces, and the movable contact surface contacts the movable end of the bellows cover X. A fixed end plate of the bellows cover X is installed on the outer side of the fixed end of the bellows cover X. The lower part of the fixed end plate of the bellows cover X is connected to the marble substrate, and a gap is provided between the fixed end plate of the bellows cover X and the end face of the marble boss. A fixed end plate of the bellows cover Y is connected to the fixed end of the bellows cover Y, and a flow guiding space is provided between the fixed end plate of the bellows cover Y and the substrate Y. A worktable is installed on the upper end of the bellows cover Y. A water-guided laser cutting head for spraying high-speed water is installed on the gantry frame. Since the bellows cover X and the bellows cover Y are themselves telescopic structures, there will be no motion interference.

[0008] Furthermore, in the aforementioned waterproof structure for motion axes applicable to laser processing equipment, the Y-axis is fixedly connected to the worktable surface, the Y-axis can drive the worktable surface to move along the Y-axis direction, and the X-axis can drive the Y-axis and the worktable surface to move along the X-axis direction.

[0009] Furthermore, in the aforementioned waterproof structure for the motion axis of laser processing equipment, the bellows cover X is a two-section structure, with the two bellows cover X sections respectively located on the left and right sides of the X-axis; the bellows cover Y is a two-section structure, with the two bellows cover Y sections respectively located on the front and rear sides of the Y-axis.

[0010] Furthermore, in the aforementioned waterproof structure for the motion axis of laser processing equipment, the connecting surface between the bellows cover X and the fixed end plate of the bellows cover X is the contact surface between the bellows cover X and the fixed end; water leaking in along the contact surface between the bellows cover X and the fixed end can flow downward along the fixed end plate of the bellows cover X and flow into the sink of the marble substrate through the gap between the fixed end plate of the bellows cover X and the marble boss; the connecting surface between the bellows cover Y and the fixed end plate of the bellows cover Y is distributed with the contact surface between the bellows cover Y and the fixed end, and water leaking in along the contact surface between the bellows cover Y and the fixed end can flow into the space between the fixed end plate of the bellows cover Y and the substrate Y.

[0011] Furthermore, in the aforementioned waterproof structure for the motion axis of laser processing equipment, the bellows cover X has an internal space X, and an X-axis is installed within the internal space X; the bellows cover Y has an internal space Y, and a Y-axis is installed within the internal space Y; guide rails, motors, and grating rulers are installed in both the internal spaces X and Y; sliders are installed on the guide rails, and guide rails are distributed between the sliders and the guide rails.

[0012] Furthermore, in the aforementioned waterproof structure for the motion axis of laser processing equipment, the marble substrate has a settling groove distributed on it, and the settling groove has several drainage outlets, so that water flowing into the settling groove of the marble substrate can flow out through the drainage outlets; the guiding space is connected to the drainage outlets, so that water flowing into the guiding space can flow out through the drainage outlets.

[0013] Furthermore, in the aforementioned waterproof structure for the motion axis of laser processing equipment, the drain outlet is equipped with a detachable filter screen; and the flow guiding space is distributed with flow guiding ribs.

[0014] By means of the above solution, this utility model has at least the following advantages: 1. By combining reserved gaps and flow guidance space, the risk of water leakage is reduced from the source. There is no need to apply waterproof glue to the installation surface of the bellows cover. The bellows cover can be removed at any time, making it easy to observe the internal space and greatly reducing the cost and difficulty of equipment maintenance.

[0015] 2. All leaked water is discharged through the guide structure and drain outlet, and will not enter the internal space of each bellows cover, which can effectively protect key components such as guide rails, motors, and grating rulers, and avoid water ingress failure.

[0016] 3. The use of an integral marble base plate 18 can improve the stability of equipment installation, facilitate subsequent unified drainage, ensure that water flows out quickly and smoothly, and eliminate the risk of water accumulation.

[0017] 4. The bellows cover Y and bellows cover X adopt a two-section structure to ensure that the corresponding motion axis does not interfere with the external bellows cover structure during the full stroke reciprocating motion, thus ensuring the processing accuracy of the equipment.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Detailed Implementation The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] like Figures 1 to 9 This invention discloses a waterproof structure for the motion axis of laser processing equipment, comprising a marble substrate 18, which overcomes the limitations of existing technologies that use separate double-layer marble substrates. The integrated marble substrate structure of this invention improves the stability of equipment installation and reduces the motion axis reference misalignment problem that easily occurs when splicing multiple substrates. Simultaneously, a conventional gantry frame for laser processing equipment is mounted on the marble substrate 18, which supports the water-guided laser cutting head 4, providing stable installation and operational support. Furthermore, a marble boss 19 is integrally formed on the marble substrate 18. This marble boss 19 provides a suitable support surface for the X-axis installation and facilitates subsequent waterproofing.

[0030] According to a preferred embodiment of this utility model, an X-axis is distributed on the marble boss 19. This X-axis is a transverse drive mechanism used to drive subsequent components to achieve transverse movement. Simultaneously, a bellows cover X2 covers the outside of the X-axis. The main function of the bellows cover X2 is to shield the X-axis and internal components, preventing debris and water mist generated during processing from directly contacting the X-axis. Specifically, to prevent interference between the bellows cover X2 and the reciprocating motion of the X-axis, the bellows cover X2 adopts a two-section structure. The two sides of the bellows cover X2 are bellows cover X fixed ends 5, which are connected to the corresponding equipment on the X-axis, achieving lateral positioning of the bellows cover X2. The middle part of the bellows cover X2 forms the bellows cover X moving end 6, which moves synchronously with the movement of the X-axis, ensuring that the X-axis is always covered by the bellows cover X2 throughout its entire stroke.

[0031] Furthermore, a sliding plate X9 is fixedly connected to the accordion cover X moving end 6. This sliding plate X9 is the load-bearing component of the X-axis moving end, and its end is machined with a stepped surface. A moving end contact surface 10 is installed on the stepped surface, and the moving end contact surface 10 is in close contact with the accordion cover X moving end 6 to form a fit, with the stepped surface concealing the moving end contact surface 10 beneath it. During use, when water splashes or flows from the worktable surface 3 onto the sliding plate X9, the water flows down along the upper surface of the stepped surface, preventing it from contacting the moving end contact surface 10 located below the stepped surface. Structurally, this directly avoids the risk of water leakage from this contact surface, completely solving the problem of needing to apply waterproof adhesive to this contact surface in existing technologies.

[0032] In practical implementation, a Y-axis is mounted on the upper end of the bellows cover X moving end 6, which is a longitudinal drive mechanism used to drive the worktable to achieve longitudinal movement. The Y-axis is covered by a bellows cover Y1, which serves the same function as the bellows cover X2, protecting the Y-axis and internal components. Similarly, to avoid interference between the bellows cover Y1 and the movement of the Y-axis, the bellows cover Y1 also adopts a two-section structure, with the two sections of the bellows cover Y1 located on the front and rear sides of the Y-axis respectively. Specifically, the inner end of the bellows cover Y1 is the bellows cover Y moving end 7, which moves synchronously with the movement of the Y-axis. The outer end of the bellows cover Y1 is the bellows cover Y fixed end 8, which is connected to the equipment fixing structure to achieve external positioning of the bellows cover Y1. A worktable 3 is mounted on the upper end of the bellows cover Y1, used to place the workpiece to be processed. Simultaneously, the Y-axis is fixedly connected to the worktable 3. During operation, the Y-axis drives the worktable 3 to reciprocate along the Y-axis direction, and the X-axis drives the Y-axis and the worktable 3 connected to the Y-axis to reciprocate along the X-axis direction. Thus, through the coordinated movement of the X-axis and Y-axis, multi-position precision machining of the workpiece on the worktable 3 is achieved.

[0033] Meanwhile, this utility model has a bellows cover X fixed end plate 11 installed on the outside of the fixed end 5 of the bellows cover X. The bellows cover X fixed end plate 11 is a plate structure, which is fixedly connected to the marble base plate 18 at its bottom to ensure installation stability. The connecting surface of the bellows cover X2 and the bellows cover X fixed end plate 11 forms the contact surface 12 between the bellows cover X and the fixed end. A gap is set between the fixed end plate 11 of the bellows cover X and the end face of the marble boss 19. The width of this gap can be designed according to the actual size of the equipment and drainage requirements, usually 2-5mm. This forms a targeted waterproof drainage path. During operation, when a small amount of water leaks in along the contact surface 12 between the bellows cover X and the fixed end, the water will flow down along the vertical surface of the bellows cover X fixed end plate 11. Since there is a gap between the fixed end plate 11 and the marble boss 19, the water will not contact the surface of the marble boss 19, but will fall directly into the recessed groove opened on the marble base plate 18. Finally, it flows out of the equipment from the drain outlet on the recessed groove.

[0034] Furthermore, a fixed end plate 14 for the bellows cover Y is connected to the fixed end 8 of the bellows cover Y. In this embodiment, a flow guiding space is provided between the fixed end plate 14 of the bellows cover Y and the substrate Y15. The connecting surface between the bellows cover Y1 and the fixed end plate 14 of the bellows cover Y forms the contact surface 13 between the bellows cover Y and the fixed end. During operation, when a small amount of water leaks in along this contact surface, the water will enter the flow guiding space between the fixed end plate 14 of the bellows cover Y and the substrate Y15, instead of flowing to the upper surface of the substrate Y15. At the same time, the flow guiding space is connected to the drain outlet on the marble substrate 18, and the water flowing into the flow guiding space can be quickly discharged out of the equipment through the drain outlet, avoiding water accumulation in the space. Of course, to improve the drainage effect and prevent the drain outlet from being blocked by processing debris and other impurities, a detachable filter screen is installed at the drain outlet, and the filter screen can be removed and cleaned periodically. Furthermore, flow guiding ribs are distributed in the flow guiding space. The flow guiding ribs are set along the water flow direction, which can guide the water flowing into the space to flow quickly to the drain outlet, shortening the drainage time.

[0035] Furthermore, this invention features an internal space X17 within the bellows cover X2, where key components such as the X-axis guide rail, motor, and grating ruler are installed. Simultaneously, an internal space Y16 is formed within the bellows cover Y1, where the corresponding key components such as the Y-axis guide rail, motor, and grating ruler are also installed. During implementation, a slider is slidably mounted on the guide rail, and the corresponding motor drives the slider to move the associated moving components. The grating ruler is used to detect the movement position in real time, ensuring machining accuracy.

[0036] Furthermore, considering the actual needs of water-guided laser cutting, the water-guided laser cutting head 4 installed on the gantry faces the worktable 3. During processing, the water-guided laser cutting head 4 uses high-speed water flow as the laser transmission medium, spraying high-speed water onto the workpiece placed on the worktable 3 to achieve workpiece cutting. The high-speed water flow generates water mist that splashes in all directions, while water accumulates on the worktable 3 and flows down along the edges. This water flow is the main water source that this waterproof structure needs to handle. Specifically, when the water splashes or flows down, most of the water flows directly into the groove of the marble substrate 18 along the pleated surfaces of the bellows cover X2 and bellows cover Y1. A small amount of water flows into the water flow along the contact surface 12 between the bellows cover X and the fixed end, and the contact surface 13 between the bellows cover Y and the fixed end. Then, it is guided into the drain hole. Thus, through the coordination of multiple structures, waterproof drainage can be achieved, and the water flow during use can be discharged outside the equipment through the drain, ensuring that the internal space of the bellows cover remains dry.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
