[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] The following is for reference. Figures 1-13 The following is a description of the material fixture 100 for laser processing and the laser processing equipment according to embodiments of the present invention.

[0044] The laser processing material clamp 100 of this utility model embodiment includes a clamping base 1, a movable clamping plate 2, and a locking component 3.

[0045] The clamping seat 1 extends with a first clamping portion 131, and a portion of the movable clamping plate 2 forms a second clamping portion 233. The second clamping portion 233 and the first clamping portion 131 are aligned in a first direction (e.g., Figure 3 and Figure 10 As shown in the diagram, the first clamping part 131 and the second clamping part 233 are arranged opposite each other, forming a clamping space extending in the second direction between them. The clamping space is capable of clamping the material 300 to be processed and a part of the fixing frame 200. The first direction and the second direction are arranged perpendicularly. The movable clamping plate 2 can be moved and adjusted in the first direction so that the second clamping part 233 moves closer to and further away from the first clamping part 131. The movable clamping plate 2 is held in a predetermined position by the locking member 3, thereby adjusting and maintaining the width of the clamping space.

[0046] The laser processing material clamp 100 of this utility model forms a first clamping part 131 on the clamping base 1 and a second clamping part 233 on a part of the movable clamping plate 2. The second clamping part 233 moves closer to and away from the first clamping part 131 by moving the movable clamping plate 2 along a first direction, thereby adjusting the clamping width of the clamping space. With the cooperation of the locking member 3, the second clamping part 233 is held in a predetermined position, thereby adjusting and maintaining the width of the clamping space. It can be used to clamp materials 300 of different thicknesses (material 300 is usually the workpiece to be processed, for example, the material can be a plate to be engraved), and can be used to fix and clamp materials 300 of different thicknesses.

[0047] The laser processing material clamp 100 of this utility model embodiment can be used to clamp materials 300 to be processed of different thicknesses, and has the advantage of good applicability.

[0048] Alternatively, laser processing can include laser engraving, laser welding, laser cutting, laser drilling, and laser cladding.

[0049] In one embodiment of this utility model, such as Figures 3 to 6 As shown, the locking member 3 is a drive locking member 3. The clamping base 1 includes a base plate segment 11, a connecting plate segment 12, and a first clamping segment 13, which are bent and connected together. The base plate segment 11 and the first clamping segment 13 are arranged opposite to each other along a first direction. The first clamping segment 13 has a first clamping part 131. The drive locking member 3 is connected to the base plate segment 11, and one end of the drive locking member 3 is connected to the movable clamping plate 2 to drive the movable clamping plate 2 to move along the first direction. It can be understood that the drive member has both a driving function and a locking function.

[0050] The laser processing material fixture 100 of this utility model embodiment divides the clamping base 1 into a base plate segment 11, a connecting plate segment 12, and a first clamping segment 13, which are bent and connected together. The base plate segment 11 and the first clamping segment 13 are arranged opposite to each other along a first direction and are connected to the base plate segment 11 by a driving locking member 3. One end of the driving locking member 3 is connected to the movable clamping plate 2, thereby realizing the limiting and driving of the movable clamping plate 2. Therefore, the laser processing material fixture 100 of this utility model embodiment has the advantages of simple structure and high processing convenience.

[0051] Optionally, the clamping base 1 is generally U-shaped. The clamping base 1 is a one-piece bent structure.

[0052] like Figure 4 and Figure 6 As shown, the drive locking member 3 includes a screw 31, which is rotatably inserted through the base plate segment 11. The screw 31 is threaded onto the movable clamping plate 2 so that the movable clamping plate 2 can be moved along the first direction by rotating the screw 31.

[0053] The laser processing material clamp 100 of this embodiment uses a screw 31 as the driving locking element 3, which is threaded onto the movable clamping plate 2. In other words, the movable clamping plate 2 is moved using a threaded structure. Furthermore, when the external force is removed, the threaded pair maintains its current position without displacement, thus achieving a self-locking effect on the movable clamping plate 2. Moreover, since threaded connections typically have a large contact area and friction, they provide good stability when subjected to large impact loads. Therefore, the laser processing material clamp 100 improves structural stability.

[0054] Optionally, the thread on the screw 31 can be a trapezoidal thread or a square thread. This type of thread structure has the advantage of good self-locking function. The thread on the screw 31 can also be a triangular thread or a rectangular thread. This type of thread structure has superior performance in improving wear resistance and extending service life.

[0055] like Figures 9 to 11 As shown, the two ends of the screw 31 are rotatably passed through the base plate section 11 and the first clamping section 13. The movable clamping plate 2 includes a movable seat section 21, a folded plate section 22 and a second clamping section 23 connected in sequence by bending. The second clamping section 23 and the movable seat section 21 are arranged opposite to each other along a first direction. The screw 31 is connected to the movable seat section 21. The second clamping section 23 has a second clamping part 233.

[0056] The laser processing material clamp 100 of this utility model has the advantages of good overall structure and simple structure by dividing the movable clamping plate 2 into a movable seat section 21, a folding plate section 22 and a second clamping section 23 that are bent and connected in sequence.

[0057] Optionally, both the substrate segment 11 and the first clamping segment 13 may be provided with insertion holes, the upper and lower segments of the screw 31 are not provided with threaded structures, and bearings may be provided between the upper segment of the screw 31 and the first clamping segment 13, and between the lower segment of the screw 31 and the substrate segment 11.

[0058] like Figure 3 , Figures 9 to 11 As shown, one end of the folding plate segment 22 is connected to the movable seat segment 21, and the other end of the folding plate segment 22 (for example, Figure 3 (As shown below) it extends in a direction away from the first clamping segment 13 and connects to the second clamping segment 23.

[0059] The laser processing material clamp 100 of this embodiment extends the other end of the folding plate segment 22 in a direction away from the first clamping segment 13 and connects it to the second clamping segment 23. As a result, with a fixed size of the material 300 to be processed, the width of the clamping space in the first direction is increased, thereby helping to reduce the overall size of the laser processing material clamp 100.

[0060] like Figure 3 , Figures 9 to 11 As shown, the second clamping segment 23 has a first surface 231 disposed opposite to the first surface along the first direction (e.g., Figure 3 The lower end face) and the second face 232 (for example, Figure 3 The second clamping section 232 is disposed opposite to the first clamping section 131, forming a second clamping section 233. The second clamping section 232 is provided with an anti-disengagement protrusion 234 facing the first clamping section 131. It can be understood that the second clamping section 23 and the first clamping section 13 are disposed opposite to each other in the vertical direction.

[0061] The laser processing material clamp 100 of this utility model can achieve clamping and limiting of the fixing frame 200 and / or the material 300 to be processed by providing an anti-disengagement protrusion 234 on the second surface 232 of the second clamping section 23 facing the first clamping part 131. As a result, the material clamp 100 improves the stability of clamping the material 300 to be processed.

[0062] like Figure 3 and Figure 10 As shown, the anti-detachment protrusion 234 is along the second direction (e.g., Figure 3 Extending in the left-right direction shown, and with the anti-disengagement protrusion 234 located on the second surface 232 away from the area of ​​the folded plate section 22, the anti-disengagement protrusion 234, the second clamping section 23, and the folded plate section 22 together form a limiting groove 20 with an opening facing the first clamping section 13 (e.g., Figure 10 (as shown above).

[0063] The laser processing material clamp 100 of this utility model can achieve limiting engagement of the fixing frame 200 by forming a limiting groove 20 with the opening facing the first clamping section 13 by the anti-detachment protrusion 234, the second clamping section 23 shown, and the folding plate section 22. This improves the stability of fixing the fixing frame.

[0064] Optionally, the fixing bracket 200 can be engaged in the limiting groove 20, and the height of the fixing bracket 200 can be level with or protrude from the upper edge of the limiting groove 20.

[0065] In other embodiments, such as Figure 8 , Figure 12 and Figure 13 As shown, the clamping seat 1 includes a bent and connected ratchet plate body 14 and a first clamping section 13. The first clamping section 13 has a first clamping part 131. The ratchet plate body 14 extends along a first direction and the first clamping section 13 is disposed on the ratchet plate body 14. The movable clamping plate 2 includes a base 24, a material ratchet clamp 32 and a clamping member 25 disposed on one side of the base 24. The base 24 is sleeved on the ratchet plate body 14, and a part of the material ratchet clamp 32 can be clamped on the ratchet plate body 14 so as to limit the base 24 through the material ratchet clamp 32.

[0066] The laser processing material clamp 100 of this utility model comprises a clamping base 1 divided into a bent and connected ratchet plate 14 and a first clamping section 13. A base 24 is fitted onto the ratchet plate 14, and a portion of the material clamp 32 is engaged and disengaged from the ratchet plate 14 to limit the position of the base 24. This structure provides relatively good stability and is less prone to shaking, preventing material 300 displacement or vibration during laser processing. The ratchet plate 14 and the material clamp 32 work together easily, facilitating rapid fixing and disassembly of materials 300 of different thicknesses.

[0067] Optionally, the base 24 is provided with teeth that match the ratchet plate 14. In its natural state, the base 24 and the material ratchet clamp 32 can only move upwards to lock the material 300, preventing it from loosening. The material ratchet clamp 32 has ratchet teeth, a limiting pin, and a torsion spring fitted on the limiting pin. The ratchet teeth are rotatably mounted on the clamping seat 1 via the limiting pin. The torsion spring can force the ratchet teeth to engage with the ratchet plate 14, and pressing the ratchet teeth can force them to disengage from the ratchet plate 14. This achieves locking and movement of the movable clamping plate 2.

[0068] like Figure 8 , Figure 12 and Figure 13As shown, the clamping member 25 includes a first clamping portion 251 and a second clamping portion 252 that are opposite to and spaced apart along a third direction. A limiting groove 20 for defining the card strip is formed between the first clamping portion 251 and the second clamping portion 252. The third direction is perpendicular to each of the first direction and the second direction.

[0069] The laser processing material clamp 100 of this utility model can achieve limiting engagement of the fixing frame 200 by means of a first clamping part 251 and a second clamping part 252 arranged opposite to each other and spaced apart along a third direction on the clamping member 25, and a limiting groove 20 for limiting the clamping strip is formed between the first clamping part 251 and the second clamping part 252.

[0070] Optionally, the first clamping part 251 is provided with a first protrusion 2511 on the side opposite to the second clamping part 252, and the second clamping part 252 is provided with a second protrusion 2521 on the side opposite to the first clamping part 251, and the blade holder of the fixing frame 200 is engaged in the limiting groove 20.

[0071] The laser processing equipment for laser processing materials according to this utility model embodiment includes a track device (not shown) and a laser device (not shown) movably mounted on the track device, as well as a fixing frame 200 and a plurality of laser processing material clamps 100 according to any one of the above, wherein a part of the fixing frame 200 and the material 300 to be processed can be clamped in the clamping space.

[0072] The laser processing material clamp 100 of this utility model has the advantage of good applicability.

[0073] In addition, movably mounting the laser device on a track device helps to increase the operating area of ​​the laser device.

[0074] Specifically, during laser processing, the material 300 to be processed is first clamped and fixed by the material fixture, and then the laser device is controlled to move on the track device and output laser. The laser hits the material 300 to be processed, and the material 300 is laser processed.

[0075] Optionally, the mounting bracket 200 includes multiple brackets along a third direction (e.g., Figure 3 The blades 201 are spaced apart in the front-to-back direction (as shown in the diagram), each blade extending along a second direction. A material clamping fixture 100 for laser processing is movably mounted on the blades 201 along their extension direction. Specifically, the blades 201 are engaged within the limiting groove 20. The material 300 is clamped between the upper wall of the blades 201 and the first clamping section 13.

[0076] Optionally, the laser processing equipment for laser processing materials in this embodiment of the present invention further includes a lifting seat, on which the fixed frame 200 can be mounted so as to rise and fall with the lifting seat.
