TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting, in particular to a clamping type limiting workpiece laser cutting machine. BACKGROUND

[0002] A laser cutting machine is a mechanical device that uses high-energy laser beams to accurately cut materials. It generates high-intensity laser beams through a laser generator, which are focused by focusing mirrors to produce high temperatures on the material surface, causing the material to melt or vaporize rapidly, while auxiliary gases such as nitrogen or oxygen are used to blow away the slag, thus achieving precise cutting. Laser cutting machines have the characteristics of high precision, high speed and high flexibility, and are suitable for processing various materials such as metals, plastics, wood and ceramics, and are widely used in industrial manufacturing, electronics, automobiles, aerospace and other fields.

[0003] The existing laser cutting machine clamping device usually uses mechanical clamps, vacuum suction cups or magnetic fixation to firmly fix the workpiece on the cleaning platform, ensuring that it does not move or vibrate during cleaning.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] 1. In the workpiece laser cutting machine with clamping type limiting, the flexible clamping of the workpiece is realized through the linkage design of the first air cylinder and the elastic piece. The stable clamping force is provided by the first air cylinder, and the elastic piece gives the clamping end certain contraction ability, so that the clamping device can adapt to the inner walls of workpieces of different sizes and shapes. This clamping mode with one end fixed and the other end elastic provides stable rigid clamping force through the first air cylinder, ensuring that the workpiece does not shift or shake during processing. The contraction ability of the elastic piece can automatically adjust the clamping force according to the shape and size of the workpiece, avoiding indentation or deformation of the workpiece surface caused by excessive clamping force. For thin-walled or easily deformed workpieces, this flexible clamping design is particularly important, because it can ensure the stability of the workpiece while dispersing the clamping pressure and reducing local stress concentration, thereby effectively preventing the workpiece from deforming or being damaged during clamping, ensuring processing precision and workpiece integrity.

[0020] 2. In the workpiece laser cutting machine with clamping type limiting, the versatility and flexibility of the lifting clamping device are realized through the universal piece. The universal piece can freely adjust the clamping angle according to the shape of the workpiece, whether it is a regular shape or a complex curved surface workpiece, it can achieve full adhesion and stable clamping. This self-adaptive clamping mode avoids the clamping instability problem caused by shape mismatch of traditional clamping devices, significantly improving clamping precision and processing quality.

[0021] 3. In the workpiece laser cutting machine with clamping type limiting, the linkage design of the positioning assembly and the smooth assembly realizes the intelligent switching of workpiece movement and fixation. When the positioning assembly touches the top of the workpiece and rotates, it can drive the workpiece to move smoothly, and the rotation of the smooth assembly further reduces the friction resistance of the workpiece movement, ensuring smooth movement. When the workpiece needs to be cut at a specific position, the positioning assembly increases the clamping force by lifting and fixes the workpiece tightly on the top of the support base, and at the same time the smooth assembly descends to make the center part of the workpiece clamped into the groove of the support base, ensuring the local stability of the cutting part, effectively preventing vibration or displacement during cutting, and improving cutting precision.

[0022] 4、The support center groove and the cooperation design of the positioning assembly further enhance the stability of the support of the workpiece; in the cutting process, the center part of the workpiece is clamped into the groove, combined with the pressing force of the positioning assembly, forming a multi-point fixation of the workpiece, effectively dispersing the stress generated during cutting, avoiding the deformation or deviation of the workpiece due to excessive local stress; at the same time, this design can also adapt to workpieces of different thickness and weight, ensuring the stability and consistency of the cutting process.

[0040] The existing laser cutting machine clamping device is usually designed for a specific shape or size, and needs to be frequently adjusted when replacing workpieces. It lacks a separate stabilizing function for the cutting part, and the support stability is insufficient during transmission, which easily leads to displacement or shaking of the workpiece, affecting the cutting precision and processing quality.

[0041] Therefore, the present application provides a workpiece laser cutting machine with clamping limiting, as shown in Figures 1-2 The workpiece laser cutting machine with clamping limiting comprises a base 1, a support 11 fixedly connected to the top of the base 1, a laser cutting device 12 fixedly connected between the outer walls of the base 1 and the support 11 near the end, and the laser cutting device 12 located above the support 11.

[0042] A sliding groove is arranged inside the support 11 near the other end, and a clamping assembly 13 is arranged inside the sliding groove of the support 11. The clamping assembly 13 comprises two universal pieces 131, which are movably connected inside the sliding groove of the support 11 near the two ends.

A spring piece 132 is arranged between the other universal piece 131 and the sliding groove of the support 11.

[0043] A recess is arranged at the center of the support 11, and a smooth assembly 15 is arranged inside the recess of the support 11. A positioning assembly 14 is arranged between the laser cutting device 12 and the clamping assembly 13 between the outer walls of the base 1 and the support 11. The positioning assembly 14 is located at the top of the support 11, and is used to clamp and stabilize the workpiece while moving the workpiece.

[0044] Firstly, the specific structure of the universal part 131 is disclosed, the universal part 131 comprises a support 1310, the support 1310 is slidingly connected in the sliding groove of the support 11, one of the supports 1310 is fixedly connected at the end of the piston rod of the No. 1 air cylinder 130, the other support 1310 is provided with an elastic piece 132 between the inner wall of the sliding groove, the inside of the support 1310 is provided with a rotating groove 1311 near the top, the rotating groove 1311 is movably clamped with a rotating ball 1313, the rotating ball 1313 is fixedly connected with an arc plate 1312 through the outer wall of the rotating groove 1311;

[0045] Referring to Figure 3 and Figure 5 As shown, by moving the two supports 1310 close to each other to drive the two arc plates 1312 close to each other, the workpiece is clamped, when the arc plate 1312 touches the workpiece, the pressure of the two supports 1310 constantly close to each other will form a counter force between the workpiece and the arc plate 1312, through the reverse force of the workpiece on the arc plate 1312, the arc plate 1312 moves to the support 1310, so that the rotating ball 1313 at the end of the arc plate 1312 rotates in the rotating groove 1311, so as to adjust the angle of the arc plate 1312;

[0046] Among them, in the field of processing, if the surface of the workpiece is sensitive, usually elastic pad is used as inner lining (not shown in the figure) to increase in the arc plate 1312, which is used to protect the surface of the workpiece, enhance the clamping stability and dispersion pressure, and also can adapt to high temperature environment, improve the durability and overall performance of the equipment.

[0047] Secondly, the specific structure of the elastic piece 132 is disclosed, the elastic piece 132 comprises a sliding rod 1320, the sliding rod 1320 is fixedly connected in the sliding groove of the support 11, the sliding rod 1320 is movably connected in one of the supports 1310, the support 1310 and the inner wall of the support 11 are provided with a first elastic piece 1321, the first elastic piece 1321 is wound on the outer wall of the sliding rod 1320;

[0048] Referring to Figure 4 and Figure 6As shown, one of the two pillars 1310 is driven by the first cylinder 130 to move towards the other pillar 1310, so as to clamp the workpiece between the two pillars 1310, at this time, the other pillar 1310 will be driven by the extrusion force of the workpiece to stretch the first elastic element 1321 outward, and the elastic resilience of the first elastic element 1321 itself will drive the pillar 1310 to contract, wherein the pillar 1310 moves on the outer wall of the sliding rod 1320 during the contraction process, and the sliding rod 1320 keeps the stability of the movement of the pillar 1310; so that the two pillars 1310 are in a state of approaching each other, one of which forms a fixed clamping force by the pressure of the first cylinder 130 to ensure that the workpiece does not shift or shake during processing, and the other forms a dynamic clamping force by the elastic contraction force of the first elastic element 1321, which can automatically adjust the clamping force according to the shape and size of the workpiece, avoiding deformation or damage of the workpiece due to excessive clamping force; this kind of clamping method which combines rigidity and flexibility is especially suitable for thin-walled or easily deformed workpieces, which can ensure stability while reducing local stress concentration.

[0049] Further, the specific structure of the positioning assembly 14 is disclosed, the positioning assembly 14 comprises a lifting element 140, two lifting elements 140 are respectively fixedly connected at the outer walls of the two sides of the support 11 and the base 1, and a fixing element 141 is arranged between the two lifting elements 140, and the fixing element 141 is located at the top of the support 11.

[0050] Referring to Figure 7 As shown, the fixing element 141 is driven by the lifting element 140 to move up and down, when the fixing element 141 touches the top of the workpiece, the workpiece is driven to move by the rotation of the fixing element 141, and the smooth assembly 15 is driven to rotate during the movement of the workpiece, improving the movement speed and smoothness of the workpiece; when the workpiece needs to be cut, the workpiece is pressed and fixed on the top of the support 11 by increasing the clamping force of the fixing element 141, and at the same time, the center part of the workpiece is clamped into the groove of the support 11 by the descent of the smooth assembly 15, ensuring the local stability of the cutting part, effectively preventing vibration or displacement during cutting, and improving the cutting precision;

[0051] Specifically, the specific structure of the lifting element 140 is disclosed, the lifting element 140 comprises a second cylinder 1400, the second cylinder 1400 is fixedly connected between the outer walls of the support 11 and the base 1, the piston rod end of the second cylinder 1400 is fixedly connected with a support rod 1401, and the two support rods 1401 are provided with a fixing element 141.

[0052] When the supporting rod 1401 moves downward, the suction cups 1411 adsorb the top of the workpiece. The motor 1413 drives the rotating rod 1412 and the rotating drum 1410 to rotate. Since the suction cups 1411 are fixed on the outer wall of the rotating drum 1410, the suction cups 1411 will rotate with the rotating drum 1410, and the rotating thrust of the suction cups 1411 acts on the workpiece, thereby driving the workpiece to move in the rotating direction of the rotating drum 1410. At the same time, the rotating rod 1511 in the smooth assembly 15 will rotate under the friction of the workpiece, reducing the moving resistance of the workpiece and ensuring the stable movement of the workpiece.

[0053] Referring to Figure 7 As shown, the supporting rod 1401 is driven by the piston rod of the No. 2 cylinder 1400 to move up and down, and the fixed part 141 is driven by the two supporting rods 1401 to move up and down, so that the auxiliary fixed part 141 clamps and positions the top of the workpiece, thereby achieving precise workpiece fixing and position adjustment. The clamping height can be flexibly adjusted according to the thickness and shape of the workpiece, so as to ensure the stability of the workpiece during cutting and avoid displacement or shaking caused by vibration or external force. At the same time, the up-down movement function of the fixed part 141 enables the clamping device to quickly adapt to workpieces of different sizes, thereby improving the versatility and operation efficiency of the equipment.

[0054] Specifically, the specific structure of the fixed part 141 is disclosed. The fixed part 141 includes a rotating rod 1412, the outer wall of the rotating rod 1412 is fixedly connected with a rotating drum 1410, the rotating drum 1410 is located between the two supporting rods 1401, one end of the rotating rod 1412 is provided with a motor 1413, and the outer wall of the rotating drum 1410 is fixedly connected with a plurality of suction cups 1411.

[0055] Referring to Figure 8 As shown, when the supporting rod 1401 moves downward, the suction cups 1411 adsorb and clamp the top of the workpiece, so as to ensure the stability of the workpiece during cutting and avoid displacement or shaking caused by vibration or external force. The rotating thrust of the suction cups 1411 can drive the workpiece to move in the rotating direction of the rotating drum 1410, thereby achieving the stable conveying of the workpiece. The advantage of this design is that it can not only accurately fix the workpiece, but also realize the automatic movement of the workpiece during cutting, thereby reducing manual intervention and improving processing efficiency. At the same time, the rotating movement of the suction cups 1411 can ensure the stability of the workpiece during movement, thereby avoiding damage to the workpiece caused by friction or impact and further improving the processing precision and workpiece integrity.

[0056] Further, the specific structure of the smooth assembly 15 is disclosed. The smooth assembly 15 includes a plurality of rolling members 151, the plurality of rolling members 151 are fixedly connected with a pressing plate 150, the bottom of the pressing plate 150 is fixedly connected with a pressure member 152, and the pressing plate 150, the rolling member 151 and the pressure member 152 are movably connected inside the support 11.

[0057] Referring to Figure 9 with Figure 10 As shown in the drawings, when the workpiece is moved under the action of the suction cup 1411, the rotation of the smooth assembly 15 can increase the power of the workpiece forward movement, reduce the pushing force of the suction cup 1411, and make the workpiece move more smoothly; the advantage of this design is that it can effectively reduce the frictional resistance during the movement of the workpiece, avoid the movement not smooth or the workpiece deviation caused by excessive resistance, and ensure the stability and accuracy of the workpiece during the conveying process; at the same time, the auxiliary rotation of the smooth assembly 15 can also reduce the load of the suction cup 1411, prolong its service life, and improve the operation efficiency of the whole equipment; in addition, this smooth movement mode can reduce the friction damage to the surface of the workpiece, and ensure the integrity and processing quality of the workpiece;

[0058] Specifically, the specific structure of the rolling member 151 is disclosed, the rolling member 151 includes a support plate 1510, the support plate 1510 is movably connected inside the plurality of grooves of the support 11, the plurality of support plates 1510 are fixedly connected through the pressing plate 150, a plurality of rotating rods 1511 are movably connected inside the support plate 1510, and the rotating shafts of the rotating rods 1511 are movably connected inside the support plate 1510.

[0059] Referring to Figure 10 As shown in the drawings, through the power of the workpiece in the moving state, the workpiece is frictioned on the surface of the rotating rod 1511 and drives the plurality of rotating rods 1511 to rotate, which can significantly improve the smoothness and stability of the workpiece movement; the advantage of this design is that the rotation of the rotating rod 1511 effectively reduces the frictional resistance between the workpiece and the support surface, so that the workpiece can move more easily and stably, and avoid the jamming or deviation caused by friction; at the same time, the rotation of the rotating rod 1511 can also disperse the pressure during the movement of the workpiece, reduce the wear on the surface of the workpiece, and ensure the integrity and processing quality of the workpiece; in addition, this design reduces the load of the driving device, improves the operation efficiency and service life of the equipment, and is particularly suitable for high-precision and high-efficiency laser cutting processing scenes;

[0060] Specifically, the specific structure of the pressure member 152 is disclosed, the pressure member 152 includes a pressure rod 1520, the pressure rod 1520 is fixedly connected at the bottom of the pressing plate 150, the pressure rod 1520 is fixedly connected with a clamping plate 1522 at the bottom, the clamping plate 1522 and the pressure rod 1520 are movably connected inside the support 11, and the outer wall of the pressure rod 1520 is wound with a second elastic member 1521, and the second elastic member 1521 is fixedly connected at the bottom of the pressing plate 150.

[0061] Referring to Figure 11As shown, when the supporting rod 1401 continuously moves downward to increase the clamping force of the suction cup 1411 on the top of the workpiece, the clamping extrusion force received by the workpiece will drive the plurality of pressing plates 150 to move downward, and when the pressing plates 150 move downward, the pressing rod 1520 and the clamping plate 1522 will move downward, at this time, the second elastic member 1521 is retracted, so that the plurality of pressing plates 150 are retracted in the support 11, and the plurality of supporting plates 1510 and the rotating rod 1511 are retracted in the support 11 at the same time through the pressing plates 150, so as to avoid continuous movement of the workpiece, and at the same time, the workpiece can contact the groove at the center of the support 11 and be clamped at the top of the groove, thereby ensuring the stability of the workpiece during cutting and avoiding displacement or shaking caused by vibration or external force, thereby improving the cutting precision; and when the workpiece is cut, the workpiece stability in the cutting state is maintained by stopping moving;

[0062] The groove of the support 11 is designed to be thin, and the workpiece is not clamped in the groove, but only supported by the two ends of the gap of the groove. This design avoids excessive pressure concentration on the surface of the workpiece. In addition, the groove is mainly used for clamping and supporting the workpiece with an arc structure, which is not convenient to clamp and is easy to roll on the support 11. For the workpiece with a flat bottom surface, the groove is not enough to clamp the workpiece, so it will not cause damage or deformation to the workpiece. This design ensures the stability of the workpiece while effectively avoiding the deformation problem caused by clamping, and is particularly suitable for processing of complex-shaped workpieces.

[0063] When the supporting rod 1401 moves upward to reduce the clamping pressure of the suction cup 1411, the elastic rebound force of the second elastic member 1521 will drive the pressing plate 150 and the pressing rod 1520 to move upward, drive the supporting plate 1510 to reset upward, and ensure the smoothness of the workpiece during movement. At the same time, the clamping plate 1522 limits the movement distance of the pressing rod 1520, ensuring the accuracy and controllability of the movement of the workpiece.

[0064] As described above, when the workpiece is placed between the two arc plates 1312, the pressure of the two supporting columns 1310 constantly approaching will form a counteracting force between the workpiece and the arc plate 1312 through the reverse force of the workpiece on the arc plate 1312, so that the arc plate 1312 moves to the supporting column 1310, and the rotating ball 1313 at the end of the arc plate 1312 rotates in the rotating groove 1311, thereby adjusting the angle of the arc plate 1312. Through the linkage of the arc plate 1312 and the elastic member 132, the clamping and self-adaptive adjustment of the workpiece are realized, the surface of the workpiece is not damaged during clamping, and the versatility and stability of the clamping device are improved.

[0065] Secondly, through the cooperation of the first air cylinder 130 and the elastic member 132, a rigid and flexible clamping mode is realized, which not only ensures the stability of the workpiece fixation, but also avoids the deformation or damage of the workpiece caused by excessive clamping force, and is particularly suitable for the machining of thin-walled or easily deformed workpieces;

[0066] Then, the positioning assembly 14 realizes precise positioning and automatic movement of the workpiece through the design of the second air cylinder 1400 and the suction cup 1411, reduces manual intervention, and improves machining efficiency; at the same time, the linkage design of the rolling member 151 and the pressure member 152 of the smooth assembly 15 ensures the smoothness and stability of the workpiece during movement, reduces friction resistance and workpiece damage;

[0067] So that the workpiece is clamped and moved individually by the positioning assembly 14; specifically, the second air cylinder 1400 drives the supporting rod 1401 to move downward, so that the suction cup 1411 adsorbs the top of the workpiece, and then the motor 1413 drives the rotating rod 1412 and the rotating cylinder 1410 to rotate, the suction cup 1411 rotates and pushes the workpiece to move; in this process, the rotating stick 1511 of the smooth assembly 15 rotates to assist the movement of the workpiece, so that it can move more smoothly and individually;

[0068] Finally, through the limiting design of the second elastic member 1521 and the clamping plate 1522 of the pressure member 152, the dynamic fixation and movement control of the workpiece during cutting are realized, ensuring the cutting precision and the integrity of the workpiece;

[0069] Finally, efficient, stable and precise machining of the workpiece is realized, which is particularly suitable for high-precision and high-efficiency laser cutting scenarios, improving the versatility, operation efficiency and machining quality of the equipment.

[0070] Working principle:

[0071] When in use, the first air cylinder 130 drives the two supporting columns 1310 to move closer to each other, so that the arc plate 1312 contacts the surface of the workpiece; at this time, the reverse force of the workpiece makes the arc plate 1312 rotate in the rotating groove 1311 through the rotating ball 1313, automatically adjusts the clamping angle, and ensures that the clamping device adapts to workpieces of different shapes and sizes;

[0072] At this time, the first air cylinder 130 provides a fixed clamping force to ensure that the workpiece does not shift or shake during machining; and the elastic member 132 forms a dynamic clamping force through the elastic rebound force of the first elastic member 1321, which can automatically adjust the clamping force according to the shape and size of the workpiece, avoiding deformation or damage of the workpiece caused by excessive clamping force; this rigid and flexible clamping mode is particularly suitable for thin-walled or easily deformed workpieces, which can ensure stability while reducing local stress concentration;

[0073] Then, the fixed part 141 clamps and positions the top of the workpiece by driving the support rod 1401 up and down by the second air cylinder 1400; the suction cup 1411 adsorbs the top of the workpiece, so that the workpiece is kept stable during cutting; the motor 1413 drives the rotating rod 1412 and the rotating drum 1410 to rotate, so that the suction cup 1411 pushes the workpiece to move stably along the direction of the rotating drum 1410, reduces manual intervention, and improves processing efficiency;

[0074] When the workpiece moves, the rotating rod 1511 of the smooth assembly 15 rotates through the friction force of the workpiece, reduces the moving resistance, and ensures that the workpiece moves smoothly; when the workpiece needs to be cut, the support rod 1401 moves downward, increases the clamping force of the suction cup 1411, and makes the workpiece clamped into the center groove of the support 11, so as to ensure the local stability of the cutting part, prevent vibration or displacement, and improve the cutting precision;

[0075] When the support rod 1401 continuously moves downward, the pressing plate 150 and the pressure part 152 are stably clamped at the top of the groove through the contraction of the second elastic part 1521, so as to ensure the stability during cutting; when the support rod 1401 moves upward, the elastic rebound force of the second elastic part 1521 drives the pressing plate 150 and the support plate 1510 to reset, so as to ensure the smoothness and accuracy of the workpiece during movement;

[0076] In addition, for a long workpiece, the stability can be ensured through the synergistic effect of various structures in the application; on the one hand, the clamping assembly 13 can flexibly clamp one end of the workpiece through the cooperation of the first air cylinder 130 and the elastic part 132, can automatically adjust the clamping force according to the shape and size of the workpiece, and ensure the stability of the clamping end; on the other hand, the positioning assembly 14 can adsorb the top of the workpiece through the suction cup 1411, increase the fixing point of the workpiece, and cooperate with the smooth assembly 15 and the groove in the center of the support 11, so that the center part of the workpiece can be clamped into the groove during movement and cutting of the workpiece, a plurality of fixing points are formed, stress is dispersed, the overall stability of the workpiece is further enhanced, and even for a long workpiece, the stability of the workpiece during cutting can be ensured to a certain extent.
