Description

Technical Field

[0001] This utility model relates to the field of water-guided laser machine tool technology, specifically a water-guided laser processing machine tool with a protective structure. Background Technology

[0002] The water-guided laser cutting machine is an innovative modern precision machining equipment that integrates high-energy laser technology and ultra-high-pressure water jet technology. It precisely couples a highly focused laser beam with an extremely fine high-pressure water jet to form a unique composite cutting method, enabling high-precision, high-efficiency cutting and fine engraving of various metal and non-metal materials. Laser cutting technology itself possesses significant advantages such as non-contact processing, narrow kerf, small heat-affected zone, and extremely high processing accuracy; while high-pressure water jet cutting technology effectively enhances cutting power, provides continuous cooling, and effectively removes slag and particles generated during the cutting process. The organic combination of these two technologies not only significantly improves cutting quality and efficiency but also expands the equipment's processing application range, making it an indispensable high-end processing equipment in modern industrial manufacturing.

[0003] However, during the cutting process of parts by the water-guided laser cutting head, the high-pressure water jet impacts the surface of the parts at high speed. This impact not only completes the cutting process but also carries a large amount of metal or non-metal debris, which splashes violently in all directions. Due to the diffusion of the water flow and the inertia of the debris, water droplets carrying debris are widely sprayed into the internal space of the equipment, causing the inner walls of the machine tool's protective housing to be almost entirely covered with dense water droplets and various debris. Subsequent manual cleaning requires a significant amount of time, thus increasing the workload for operators. Therefore, a water-guided laser processing machine tool with a protective structure is proposed. Utility Model Content

[0004] Based on this, the present invention aims to solve at least one of the technical problems existing in the prior art. To this end, a water-guided laser processing machine tool with a protective structure is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-guided laser processing machine tool with a protective structure, comprising a machine tool body, wherein a load-bearing plate for supporting the processed parts is assembled inside the machine tool body, a fixture plate for positioning a jig is assembled on the top of the load-bearing plate, drainage outlets for drainage are provided at both ends of the load-bearing plate, and a protective component capable of preventing debris from splashing is assembled on the top of the load-bearing plate.

[0006] The protective component includes an outer frame mounted on the top of the load-bearing plate. The top of the outer frame is provided with an inner liner frame that can slide and adjust along its height. A top frame is fixed to the top of the inner liner frame. The inner walls of the top frame are provided with two sets of mutually perpendicular and horizontally retractable W-shaped rubber plates. Side strips are fixed to both sides of the W-shaped rubber plates. Guide sleeves are fixed to both ends of the side strips located in the middle of the top frame. The inner wall of the top frame is provided with a travel groove along its length for the guide sleeves to slide. A traction rope is fixed between the two sets of guide sleeves arranged opposite each other.

[0007] As a preferred technical solution, the protection component further includes a guide rod disposed inside the travel groove. The two ends of the guide rod pass through two sets of guide sleeves and are fixed to the inner wall of the travel groove. A reset spring for resetting the guide sleeves is sleeved on the outer wall of the guide rod near both ends.

[0008] As a preferred technical solution, two sets of drainage plates are fixed on both sides of the outer frame, and a clearance opening is provided on the outer wall of the outer frame between the two sets of drainage plates.

[0009] As a preferred technical solution, the top frame is composed of four sets of trapezoidal plates spliced ​​end to end. Each set of trapezoidal plates has a constraint strip at its bottom and on the outside of the inner lining frame. The constraint strip is fixed to the inner and outer walls of the inner lining frame with bolts.

[0010] As a preferred technical solution, a wastewater frame that can slide to the outside is installed at the bottom of the machine tool body, and the wastewater frame can collect wastewater discharged from the drain outlet.

[0011] As a preferred technical solution, the top of the load-bearing plate is provided with inclined portions at both sides, and the inclined portions and the drainage plates on the sides of the outer frame form a drainage channel.

[0012] As a preferred technical solution, the front surface of the machine tool body is provided with a machine tool door that can be rotated and opened, and the outer side wall of the machine tool body is equipped with a control panel that can control the start and stop of the machine tool.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention features an adjustable-height inner frame and top frame, along with a retractable W-shaped rubber plate. During processing, a unit processing opening is formed above the part to prevent the splashing of wastewater and debris, thus protecting the parts inside the machine tool. When the laser cutting head moves, the W-shaped rubber plate folds and extends to move the unit processing opening synchronously, ensuring that the splashed mixture is always blocked throughout the entire processing process, thus protecting the cleanliness of the machine tool's interior.

[0015] In addition, the drainage plates on both sides of the outer frame and the inclined parts of the load-bearing plates form drainage channels, which guide wastewater containing debris to the drain outlet and finally collect it in the wastewater frame. This greatly reduces the adhesion of debris inside the machine tool, reduces the amount of manual cleaning, and improves the maintenance efficiency of the machine tool and the cleanliness of the processing environment.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A water-guided laser processing machine tool with a protective structure, such as Figures 1 to 8 As shown, the machine tool includes a machine tool body 100, a load-bearing plate 150 for supporting the machined parts is installed inside the machine tool body 100, a clamping plate 170 for positioning fixtures is installed on the top of the load-bearing plate 150, drain outlets 161 for drainage are opened at both ends of the load-bearing plate 150, and a protective component 200 for preventing debris from splashing is installed on the top of the load-bearing plate 150.

[0029] The protective component 200 includes an outer frame 220 mounted on the top of the load-bearing plate 150. The top of the outer frame 220 is provided with an inner liner frame 240 that can slide and adjust along its height. A top frame 241 is fixed to the top of the inner liner frame 240. The inner walls of the top frame 241 are provided with two sets of mutually perpendicular and horizontally retractable W-shaped rubber plates 250. Side strips 251 are fixed to both sides of the W-shaped rubber plates 250. Guide sleeves 254 are fixed to both ends of the side strips 251 located in the middle of the top frame 241. The inner wall of the top frame 241 is provided with a travel groove 242 for sliding of the guide sleeves 254 along its length. A traction rope 252 is fixed between the two sets of guide sleeves 254 arranged opposite to each other.

[0030] Two symmetrical W-shaped rubber plates 250 cooperate with the inner liner frame 240, installed directly above the part, forming a unit processing port. This exposes only a limited area of ​​the part's top, effectively preventing water-carried debris mixtures from splashing onto other parts inside the machine tool during processing, thus avoiding contamination or damage. When the water-guided laser head inside the machine tool moves laterally or longitudinally to process the part, the water-guided laser head contacts and presses the edge strip 251, causing it to move towards one side of the top frame 241, as shown in the attached manual. Figure 4 and Figure 5 As shown, the unit processing port can dynamically adjust its position according to the movement direction of the water-guided laser head, ensuring that the splashed mixture is always blocked during the entire processing process to protect the cleanliness of the machine tool's interior.

[0031] The protection component 200 also includes a guide rod 260 disposed inside the travel groove 242. The two ends of the guide rod 260 pass through two sets of guide sleeves 254 and are fixed to the inner wall of the travel groove 242. A reset spring 255 for resetting the guide sleeves 254 is sleeved on the outer wall of the guide rod 260 near the two ends.

[0032] When the water-guided laser head moves and generates thrust on the edge strip 251, the edge strip 251 is pushed by the external force and begins to move (laterally or longitudinally); simultaneously, the guide sleeve 254 moves synchronously within the stroke groove 242, sliding along the axis of the guide rod 260, while compressing the return spring 255, providing a power source for the subsequent reset of the edge strip 251; another edge strip 251 arranged parallel to it can be pulled by the traction rope 252 to move in the same direction. During this process, the W-shaped rubber plate 250 is subjected to traction force, and its shape gradually changes from the initial W state to a horizontal state, causing the position of the unit processing port to move synchronously (as per the instruction manual). Figure 5 As shown in the figure, this effectively blocks the mixture and protects the internal parts of the machine tool.

[0033] Locking bolts 222 are rotatably connected to both sides of the outer frame 220, and the ends of the locking bolts 222 abut against the outer wall of the inner lining frame 240.

[0034] The inner liner frame 240 can slide upward along the height direction of the outer frame 220. The inner liner frame 240 can be fixed in the required position by rotating the locking bolt 222, thereby adapting to the processing requirements of parts of different heights.

[0035] The top frame 241 is composed of four sets of trapezoidal plates spliced ​​end to end. Each set of trapezoidal plates has a constraint strip 270 at the bottom and on the outside of the inner frame 240. The constraint strip 270 is fixed to the inner and outer walls of the inner frame 240 with bolts.

[0036] The top of its edge strip 251 is welded with a positioning piece that is detachable from the trapezoidal plate.

[0037] The four trapezoidal plates can be installed separately and fixed to the top of the inner lining frame 240, which effectively improves the flexibility of disassembly and assembly of the inner W-shaped rubber plate 250, making it easy to operate when replacement or maintenance is needed, and saving time and labor costs for subsequent maintenance work.

[0038] It is worth mentioning that a wastewater frame 140 that can slide to the outside is installed at the bottom of the machine tool body 100. The wastewater frame 140 can collect the wastewater discharged from the drain outlet 161.

[0039] After the machine tool equipment has finished operating, the wastewater frame 140 can be manually pulled out by the staff, which makes it easy to thoroughly remove and clean the wastewater mixture accumulated inside the frame.

[0040] As per the instruction manual Figure 3 and Figure 4 As shown, ear plates 230 are fixed to the front and rear of the outer frame 220. The ear plates 230 are bolted to the top of the load-bearing plate 150 and work with the clamp plate 170 to allow the parts to be processed in a limited space.

[0041] The top of the clamping plate 170 has a dovetail groove along its length. The dovetail groove has a trapezoidal cross-section and its inclined surfaces on both sides have guiding and self-locking functions. The clamps used to fix the parts can be quickly installed and tightened by the engagement of bolts with the dovetail groove. The bolt heads can be inserted into the groove to slide and adjust their position, and are locked by nuts on the narrow side of the dovetail groove. This connection method allows the clamps to be stably fixed on the upper surface of the clamping plate 170, and also facilitates flexible adjustment of the clamp layout according to processing requirements.

[0042] Please refer to this carefully. Figure 2 and Figure 3 The top of the load-bearing plate 150 is provided with inclined parts 160 at both sides of the edge. The inclined parts 160 and the diversion plate 210 on the side of the outer frame 220 form a drainage channel.

[0043] Two sets of diversion plates 210 are fixed on both sides of the outer frame 220. The bottom of the diversion plate 210 abuts against the inclined part. A clearance opening 221 is provided on the outer wall of the outer frame 220 between the two sets of diversion plates 210.

[0044] Water discharged from the clamp plate 170 first flows naturally from the relief port 221 to the inclined part 160, ensuring that the water can be smoothly introduced into the drainage ditch. In the drainage ditch, the water flows quickly along the guiding direction of the channel and finally reaches the drain outlet 161. The drain outlet 161 serves as the outlet point, guiding the water flow to the wastewater frame 140, which awaits regular manual cleaning by the operator.

[0045] Please refer to this carefully. Figure 1 The front surface of the machine tool body 100 is provided with a machine tool door 110 that can be rotated and opened. The machine tool door 110 is connected by hinges and can be easily rotated to provide convenient access to the internal space. The outer side wall of the machine tool body 100 is equipped with a control screen 120 that can control the start and stop of the machine tool. The control screen adopts a touch interface and integrates multiple function buttons for monitoring the operating status and adjusting parameters. The side of the machine tool body 100 away from the control screen 120 is provided with a detachable plate 130 to facilitate the inspection and maintenance of internal components. The detachable plate 130 is fixed with bolts, which facilitates disassembly and maintenance and ensures operational safety and efficiency.
