Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, and specifically relates to a laser cutting machine for simultaneous processing of multiple workpieces. Background Technology

[0002] In the field of laser cutting technology, laser cutting machines are widely used for processing various workpieces due to their high precision and high efficiency. However, traditional laser cutting machines generally face some problems that urgently need to be solved when processing multiple workpieces.

[0003] Existing laser cutting machines typically only allow for the clamping and processing of a single workpiece at a time. When processing multiple workpieces, frequent manual loading, unloading, positioning, and clamping operations are required, which not only consumes significant time and labor costs but also results in low processing efficiency. Furthermore, manual positioning and clamping methods cannot guarantee completely consistent positional accuracy for each workpiece, easily leading to positioning deviations and consequently affecting the consistency of processing quality.

[0004] Meanwhile, traditional laser cutting machines mostly use simple single-point or double-point clamping structures, which offer limited stability for the workpiece. During the cutting process, the workpiece is prone to wobbling or displacement, especially for complex-shaped or small-sized pieces. Insecure clamping can lead to decreased cutting accuracy or even scrap the workpiece. Furthermore, traditional clamping structures have poor versatility and are difficult to adapt to the processing needs of workpieces of different specifications and shapes. When processing different types of workpieces, large-scale adjustments or replacements of the clamping structure are often required, further reducing production efficiency. Utility Model Content

[0005] This utility model addresses the problems of existing technologies by providing a laser cutting machine for simultaneous processing of multiple workpieces, with the specific technical solution as follows:

[0006] Laser cutting machines that process multiple workpieces simultaneously include:

[0007] A base is installed on a horizontal surface, and the base has a processing area in the middle for placing workpieces;

[0008] The gantry frame is slidably mounted above the base;

[0009] A cutting assembly, which is slidably mounted on a gantry frame;

[0010] Also includes:

[0011] A support member is disposed in the processing area, and the upper surface of the support member is provided with positioning holes for positioning the workpiece;

[0012] The clamping assembly is disposed inside the support and corresponds to the positioning hole. The clamping assembly includes a base plate and clamping arms. At least three sets of clamping arms are provided and are evenly distributed around the positioning hole. When the base plate descends, the at least three sets of clamping arms synchronously move towards the center and clamp the workpiece.

[0013] The clamping arm includes a supporting side plate, an arm body, a rotating shaft, and a connecting rod. The supporting side plate is installed inside a support member to support the arm body. The arm body is rotatably connected to the supporting side plate via the rotating shaft, and the arm body is divided into a force-applying part and a clamping part with the rotation center as the base point. The connecting rod is rotatably connected between the base plate and the force-applying part of the arm body. When the base plate descends, it can drive the force-applying part of the arm body to descend synchronously, so as to drive the clamping part of the arm body to clamp the workpiece.

[0014] As a further technical solution of this utility model, the clamping end of the force-applying part of the arm body is provided with a rough surface.

[0015] As a further technical solution of this utility model, it also includes a drive assembly, which is disposed below the clamping assembly and is used to drive multiple sets of base plates to lift synchronously. The drive assembly includes a connecting plate and a drive cylinder. The connecting plate is slidably disposed inside the support member, and the base plate is mounted on the connecting plate. The drive cylinder is mounted at the bottom of the support member, and its output end extends into the support member and is connected to the connecting plate.

[0016] As a further technical solution of this utility model, the support member is provided with multiple sets of equal spacing along the first direction in the processing area, and the positioning holes are provided with multiple sets along the second direction on the upper surface of the support member, wherein the first direction and the second direction are perpendicular.

[0017] As a further technical solution of this utility model, two slide rails are symmetrically laid on the upper part of the base along its length, and the gantry frame is slidably mounted on the upper part of the base through the slide rails. The sliding direction of the cutting component relative to the gantry frame is perpendicular to the laying direction of the slide rails.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) Synchronous clamping mechanism of the fixed clamping assembly;

[0020] The clamping assembly includes a base plate and at least three sets of clamping arms evenly distributed around positioning holes. When the base plate descends, the force-applying part of the arm body descends synchronously via a connecting rod, causing the clamping part to rotate and clamp the workpiece. The clamping arms adopt a lever-type structure of "force-applying part + clamping part", and the force is transmitted through a rotating shaft. During clamping, not only is a horizontal clamping force generated, but also a vertical downward pressure is applied, which restricts the horizontal and vertical displacement of the workpiece and improves clamping stability.

[0021] Meanwhile, multiple clamping arms are evenly distributed around the circumference, which can automatically center the workpiece and avoid machining deviations caused by eccentric clamping.

[0022] (2) Synchronous drive of multiple base plates;

[0023] The drive assembly integrates and connects multiple base plates through a connecting plate. A single drive cylinder drives the connecting plate to lift and lower, achieving synchronous movement of all clamping arms. This avoids the complex structure of traditional multi-station independent drive, simplifies the control system, reduces costs, and ensures consistent clamping force for each workpiece, thus improving processing consistency.

[0024] (3) Array layout of support components and positioning holes;

[0025] Multiple sets of support components are evenly spaced along the first direction within the processing area. Each set of support components has multiple positioning holes on its upper surface along the second direction, forming a regular matrix positioning structure. This allows for the simultaneous positioning of multiple workpieces, enabling orderly arrangement of multiple workpieces and laying the foundation for batch processing.

[0026] (4) Modular structure design;

[0027] The support components, clamping assemblies, and drive assemblies form independent modules, allowing for flexible adjustment of the support component spacing, the number of positioning holes, and the layout of the clamping arms according to the workpiece size and processing requirements, thereby enhancing the equipment's versatility.

[0037] This laser cutting machine, capable of simultaneously processing multiple workpieces, includes a base 100, a gantry frame 200, and a cutting assembly 300, wherein:

[0038] The base 100 is installed on a horizontal plane to support the entire laser cutting machine. The base 100 has a processing area 110 in the middle for placing workpieces. Two slide rails 120 are laid along the length of the processing area 110. The two slide rails 120 are symmetrically distributed on both sides of the base 100 to guide the movement trajectory of the gantry 200.

[0039] The gantry 200 is slidably mounted above the base 100 via the slide rail 120, and is used to drive the cutting assembly 300 to move along the slide rail 120 on the base 100 to cut the workpiece placed on the processing area 110.

[0040] The cutting component 300 is slidably mounted on the gantry 200, and the sliding direction of the cutting component 300 relative to the gantry 200 is perpendicular to the laying direction of the slide rail 120; that is, the movable direction of the cutting component 300 and the movable direction of the gantry 200 form a planar coordinate system on the horizontal projection plane, thereby enabling precise cutting at any point within the processing area 110 while fully covering the processing area 110; it should be noted that the cutting component 300 adopts existing cutting technology, and this application does not make any further improvements to the cutting component 300.

[0041] This laser cutting machine, capable of simultaneously processing multiple workpieces, also includes a support component 400, a clamping assembly 500, and a drive assembly 600, wherein:

[0042] The support member 400 is set in the processing area 110 and is arranged in multiple sets at equal intervals along the first direction. The upper surface of the support member 400 is provided with multiple positioning holes 410 along the second direction for positioning the workpiece. The first direction and the second direction are perpendicular. Multiple toothed workpieces can be corresponding to the several neatly arranged positioning holes 410 distributed in the processing area 110, which is conducive to the synchronous processing of multiple workpieces.

[0043] It should be noted that the bottom of the toothed workpiece is coaxially connected to a positioning shaft for easy installation and positioning. It is generally hollowed out by a support member 400.

[0044] The clamping assembly 500 is disposed within the support member 400 and corresponds to the positioning holes 410. Here, "corresponding" refers to the correspondence in both quantity and position, and is used to clamp the workpiece. The clamping assembly 500 includes a base plate 510 and clamping arms 520. At least three sets of clamping arms 520 are provided, evenly distributed around the workpiece. When the base plate 510 descends, the at least three sets of clamping arms 520 synchronously move towards the center and clamp the workpiece. The clamping arm 520 includes a supporting side plate 521, an arm body 522, a rotating shaft 523, and a connecting rod 524. The supporting side plate 521 is installed within the support member 400 to support the arm body 522. The arm body 522 is rotatably connected to the supporting side plate 521 via the rotating shaft 523, and the arm body 522 is divided into force-applying sections with the rotation center as the base point. The clamping and force-applying parts interfere with each other via a rotating shaft 523; the connecting rod 524 is rotatably connected between the base plate 510 and the force-applying part of the arm 522; when the base plate 510 descends, it can drive the force-applying part of the arm 522 to descend synchronously, so as to drive the clamping part of the arm 522 to clamp the workpiece; and multiple sets of circumferentially evenly arranged arms 522 can center the workpiece, and since the force-applying part of the arm 522 is a rotary clamping, it not only has a clamping force in the horizontal direction, but also a vertical downward pressure, which can restrict the movement of the workpiece in both the horizontal and vertical directions and improve the clamping effect; the clamping end of the force-applying part of the arm 522 is provided with a rough surface to increase the friction with the workpiece during clamping.

[0045] A drive assembly 600 is positioned below the clamping assembly 500 and is used to drive multiple sets of base plates 510 to rise and fall synchronously. The drive assembly 600 includes a connecting plate 610 and a drive cylinder 620. The connecting plate 610 is slidably disposed within the support member 400, and the base plates 510 are mounted on the connecting plate 610. The drive cylinder 620 is mounted at the bottom of the support member 400, with its output end extending into the support member 400 and connected to the connecting plate 610. The drive cylinder 620 drives the connecting plate 610 to rise and fall, thereby driving the multiple sets of base plates 510 to rise and fall synchronously, thus controlling the simultaneous movement of the base plates.

[0046] Control multiple sets of arm body 522 swings.

[0047] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
