Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically a multi-axis laser cutting device for chassis sheet metal processing. Background Technology

[0002] Chassis sheet metal processing refers to the manufacturing process of producing electronic device housings or structural components using metal sheets through cutting, bending, stamping, welding, and other processes. Its core lies in transforming planar metal sheets into three-dimensional enclosure structures with specific functions, which must meet requirements such as electromagnetic shielding, heat dissipation and ventilation, mechanical strength, and assembly accuracy. The processing involves high-precision dimensional control, complex hole and slot cutting, and surface treatment, and must balance production efficiency with performance characteristics such as corrosion resistance, shock resistance, and dustproofing. It is a key basic process in the field of electronic device hardware manufacturing.

[0003] Existing sheet metal processing and cutting equipment typically relies on manual adjustment of the clamps when holding workpieces of different sizes. This operation is cumbersome and it is difficult to ensure symmetrical clamping force. Instability in clamping can easily lead to a decrease in cutting accuracy. The rigid contact surfaces of traditional clamps are prone to indentation or scratches on the workpiece surface, posing a quality hazard, especially when processing surface-treated sheet metal. Cooling systems often use large-area spraying, which cannot accurately cover the laser action area. This not only wastes coolant but can also cause local overheating and deformation due to uneven water flow distribution. Metal chips generated during cutting often fall directly into open collection tanks, requiring frequent machine shutdowns for cleaning. The mixture of chips and coolant can easily clog drainage channels, affecting continuous operation efficiency. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

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

[0026] Reference Figures 1 to 5 In this embodiment of the present invention, a multi-axis laser cutting device for chassis sheet metal processing includes: a support platform 1, wherein the support platform 1 adopts a steel plate welded frame structure, and a horizontal base plate 2 is welded to the middle area of ​​its top. The base plate 2 is a rectangular plate structure, and two parallel slide rails 3 are symmetrically welded to its outer edge. The slide rails 3 are fixed to the upper surface of the support platform 1 by bolts. A detachable mounting plate 4 is embedded in the inner side of the base plate 2. Multiple drainage holes are evenly opened on the surface of the mounting plate 4 for draining the coolant generated during the cutting process. An annular water baffle is welded to the outer periphery of the upper surface of the base plate 2 to prevent liquid overflow.

[0027] Two sets of clamping assemblies 5 are symmetrically fixed at both ends of the upper surface of the mounting plate 4 near the slide rail 3. Each set of clamping assemblies 5 includes a fixed seat 51 vertically welded to the mounting plate 4. A cylinder 52 is fixed to the side wall of the fixed seat 51 through a flange. The piston rod of the cylinder 52 passes horizontally through the side wall of the fixed seat 51, and its end is connected to a movable seat 53 through a thread. The movable seat 53 is hinged to an adjusting rod 54 through a movable shaft. The end of the adjusting rod 54 is rotatably connected to a connecting rod 55 through a pin. An adjusting plate 56 is welded to the bottom of the connecting rod 55. A clamping plate 57 is vertically welded to the end of the adjusting plate 56. A rubber pad is provided on the inner side of the clamping plate 57 to provide flexible clamping when in contact with the workpiece. When the cylinder 52 pushes the movable seat 53 to move laterally, the adjusting rod 54 swings around the movable shaft, driving the connecting rod 55 to drive the adjusting plate 56 and the clamping plate 57 to move synchronously, realizing symmetrical adjustment of the distance between the two sets of clamping plates 57 to adapt to the clamping requirements of sheet metal workpieces of different sizes.

[0028] An electric sliding seat 6 is slidably connected to the slide rail 3. The electric sliding seat 6 moves laterally by a ball screw driven by a servo motor. A horizontally extending crossbeam 7 is welded to the top of the side wall of the electric sliding seat 6. A sliding component 8 is slidably connected to the crossbeam 7 by a linear guide rail. A laser cutting assembly 9 is fixed to the side wall of the sliding component 8. The laser cutting assembly 9 includes a liftable laser head, whose vertical height can be adjusted by a control device to adapt to different thickness plates. A sprayer 10 is fixed to the side wall of the laser cutting assembly 9. A nozzle is installed at the bottom of the sprayer 10, and the nozzle is aligned with the cutting point directly below the laser head. A water pipe 11 is connected to the top of the sprayer 10. The water pipe 11 is connected to a coolant supply device to spray cooling water onto the cutting area to reduce the heat impact.

[0029] A drainage board 12 is fixed below the base plate 2 by a bracket. The drainage board 12 is an inclined trough-shaped structure with multiple sets of parallel slots 13 on its inner sidewall. A barrier net 14 is movably inserted into each slot 13. Rubber clips 15 are glued to the sides of the barrier net 14, forming an interference fit with the slots 13 through elastic deformation. A blocking telescopic rod 16 is welded to the front of the barrier net 14. The blocking telescopic rod 16 consists of a rotating seat and a metal telescopic rod. By rotating the telescopic rod, its extension length is adjusted so that the end of the telescopic rod abuts against the inner wall of the drainage board 12, thereby locking the position of the barrier net 14. A movable rod 17 is welded to the outside of the drainage board 12. When it is necessary to clean up debris, the movable rod 17 is pulled to pull out the drainage board 12, exposing the barrier net 14 for debris dumping.

[0030] The working principle of this utility model is as follows:

[0031] When the sheet metal workpiece is placed on the mounting plate 4 of the support platform 1, the cylinder 52 of the clamping assembly 5 is activated. The piston rod of the cylinder 52 pushes the movable seat 53 to move laterally, causing the adjusting rod 54 to swing around the movable axis. The connecting rod 55 at the end of the adjusting rod 54 is displaced with the swing, thereby driving the adjusting plate 56 to move the clamping plate 57 towards the workpiece. Through the reciprocating extension and retraction of the cylinder 52, the swing angle of the adjusting rod 54 can change the distance between the two sets of clamping plates 57 in real time, thereby adapting to the clamping requirements of workpieces of different sizes. The rubber pad on the inner side of the clamping plate 57 fixes the workpiece by friction, while avoiding scratching the surface.

[0032] The laser cutting assembly 9 moves laterally along the slide rail 3 via the electric sliding seat 6. At the same time, the sliding component 8 drives the laser cutting assembly 9 to move longitudinally along the crossbeam 7, achieving multi-axis linkage positioning. When the laser head is aligned with the workpiece cutting point, the sprayer 10 sprays cooling water onto the cutting area simultaneously. The water is supplied from the outside through the water pipe 11 and directly covers the high-temperature laser action area to reduce thermal deformation. The metal debris generated during cutting flows into the drainage hole of the base plate 2 with the cooling water. After entering the drainage plate 12, the debris carried by the water flow is intercepted by the barrier net 14. The filtered water is discharged through the slot 13. The barrier net 14 is elastically engaged with the slot 13 through the rubber block 15. The blocking telescopic rod 16 locks the position of the barrier net 14 by angle adjustment to prevent the water flow from causing displacement.

[0033] During the cutting process, if it is necessary to clean up the debris, the moving rod 17 can be manually operated to move the entire drainage plate 12, so that the barrier net 14 can be exposed to remove the trapped material. The drainage holes on the surface of the mounting plate 4 cooperate with the annular baffle plate to guide the cooling water to the drainage plate 12 in a directional manner, so as to prevent the liquid from splashing to the outside of the equipment.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
