Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and more specifically, to a workpiece laser cutting machine with a clamping type limit. Background Art

[0002] A laser cutting machine is a mechanical device that uses a high-energy laser beam to precisely cut materials. It generates a high-intensity laser beam through a laser generator. After being focused by a focusing mirror, it generates high temperature on the material surface, causing the material to quickly melt or vaporize. At the same time, with the help of auxiliary gases (such as nitrogen, oxygen), the molten slag is blown away, thus achieving precise cutting. Laser cutting machines have the characteristics of high precision, high speed, and high flexibility, and are suitable for the processing of various materials such as metals, plastics, woods, and ceramics, and are widely used in industrial manufacturing, electronics, automobiles, aerospace and other fields.

[0003] The existing clamping devices of laser cutting machines usually firmly fix the workpiece on the cleaning platform by means of mechanical clamps, vacuum suction cups or magnetic fixation, etc., to ensure that it does not move or vibrate during the cleaning process. Mechanical clamps adapt to workpieces of different shapes and sizes through adjustable jaws or pressure plates; vacuum suction cups use negative pressure to adsorb flat workpieces; magnetic fixation is suitable for ferromagnetic materials. The design of the clamping device aims to ensure the stability of the workpiece, while facilitating quick clamping and disassembly to improve the cleaning efficiency and ensure the consistency of the cleaning effect.

[0004] Since the existing clamping devices of laser cutting machines are usually designed for workpieces of specific shapes or sizes, when changing workpieces, it is necessary to frequently adjust or replace the clamping devices, which increases the operation complexity and time cost and is not convenient for flexibly adapting to workpieces of different shapes, sizes or weights; in addition, the traditional clamping devices lack a separate stable function for the cutting part, resulting in easy displacement of the workpiece due to vibration or external force during the cutting process, affecting the cutting accuracy; at the same time, the existing devices have insufficient support stability for the workpiece during cutting, especially during the movement of the conveying device, it is easy to cause the workpiece to shake or shift, further reducing the processing quality.

[0005] Based on this, the present invention discloses a workpiece laser cutting machine with a clamping type limit. Summary of the Invention

The positioning assembly is located on the top of the support. The positioning assembly is used for clamping and stabilizing the workpiece and driving the workpiece to move at the same time.

[0009] As a further improvement of the technical solution, the universal joint includes a strut. The strut is slidably connected inside the chute of the support.

[0010] Preferably, a rotating groove is arranged near the top inside the strut. A rotating ball is movably clamped inside the rotating groove. The outer wall of the rotating ball passing through the rotating groove is fixedly connected with an arc plate.

[0011] As a further improvement of the technical solution, the elastic member includes a sliding rod. The sliding rod is fixedly connected inside the chute of the support. The sliding rod is movably communicated inside one of the struts. A first elastic member is arranged between the strut and the inner wall of the support. The first elastic member is wound around the outer wall of the strut.

[0012] As a further improvement of the technical solution, the positioning assembly includes a lifting member. The two lifting members are respectively fixedly connected to the outer walls of both sides of the support and the base. A fixing member is arranged between the two lifting members. The fixing member is located on the top of the support.

[0013] Preferably, the lifting member includes a second cylinder. The second cylinder is fixedly connected between the outer walls of the support and the base. The end of the piston rod of the second cylinder is fixedly connected with a support rod. A fixing member is arranged between the two support rods.

[0014] Preferably, the fixing member includes a rotating rod. A rotating cylinder is fixedly connected to the outer wall of the rotating rod. The rotating cylinder is located between the two support rods. A motor is arranged at one end of the rotating rod. A plurality of suction cups are fixedly connected to the outer wall of the rotating cylinder.

[0015] As a further improvement of the technical solution, the smooth assembly includes a plurality of rolling members. A pressing plate is fixedly connected between the plurality of rolling members. Pressure members are fixedly connected to the bottoms of the plurality of pressing plates. The pressing plate, the rolling members and the pressure members are all movably connected inside the support.

[0016] Preferably, the rolling elements include support plates which are movably connected inside a plurality of grooves of the support seat. The plurality of support plates are fixedly connected by a pressing plate. A plurality of rotating rods are movably connected inside the support plates, and the rotating shafts of the rotating rods are movably communicated inside the support plates.

[0017] Preferably, the pressing member includes a pressing rod fixedly connected to the bottom of the pressing plate. A clamping plate is fixedly connected to the bottom of the pressing rod. Both the clamping plate and the pressing rod are movably connected inside the support seat. A second elastic member is wound around the outer wall of the pressing rod, and the second elastic member is fixedly connected to the bottom of the pressing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this clamping type workpiece laser cutting machine, through the linkage design of the first cylinder and the elastic member, flexible clamping of the workpiece is realized; a stable clamping force is provided by the first cylinder, while the elastic member endows the clamping end with a certain contraction ability, enabling the clamping device to adapt to the inner walls of workpieces with different sizes and shapes; this clamping method with one end fixed and one end elastic provides a stable rigid clamping force through the first cylinder to ensure that the workpiece does not displace or shake during the processing, and the contraction ability of the elastic member can automatically adjust the clamping force according to the shape and size of the workpiece to avoid causing indentation or deformation on the workpiece surface due to excessive clamping force; for thin-walled or easily deformable workpieces, this flexible clamping design is particularly important because it can disperse the clamping pressure while ensuring the stability of the workpiece, reducing local stress concentration, thereby effectively preventing the workpiece from deforming or being damaged during clamping and ensuring the machining accuracy and workpiece integrity.

[0020] 2. In this clamping type workpiece laser cutting machine, the versatility and flexibility of the clamping device are improved through the universal joint; the universal joint can freely adjust the clamping angle according to the shape of the workpiece, and can achieve full fitting and stable clamping for both regular-shaped and complex-curved workpieces; this adaptive clamping method avoids the problem of unstable clamping caused by shape mismatch of traditional clamping devices, and significantly improves the clamping accuracy and machining quality.

[0021] 3. In this clamping type workpiece laser cutting machine, the linkage design of the positioning component and the smooth component realizes the intelligent switching between the movement and fixation of the workpiece; when the positioning component touches the top of the workpiece and rotates, it can drive the workpiece to move smoothly, and the rotation of the smooth component further reduces the frictional resistance of the workpiece movement to ensure smooth movement; when it is necessary to cut a specific position of the workpiece, the positioning component increases the clamping force through lifting to press and fix the workpiece on the top of the support seat, and at the same time the smooth component descends to make the central part of the workpiece snap into the groove of the support seat to ensure the local stability of the cutting part, effectively preventing vibration or displacement during cutting and improving the cutting accuracy.

[0022] 4. In the workpiece laser cutting machine with a clamping type limit, the matching design of the center groove of the support and the positioning component further enhances the support stability of the workpiece; during the cutting process, the central part of the workpiece is clamped into the groove, combined with the pressing force of the positioning component, forming multi-point fixation of the workpiece, effectively dispersing the stress generated during cutting, and avoiding deformation or deviation of the workpiece due to excessive local stress; at the same time, this design can also adapt to workpieces of different thicknesses and weights, ensuring the stability and consistency of the cutting process.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The clamping devices of existing laser cutting machines are usually designed for specific shapes or sizes, and require frequent adjustments when changing workpieces. They lack the function of stabilizing the cutting part separately, and the support stability is insufficient during the transmission process, which can easily cause the workpiece to shift or shake, affecting the cutting accuracy and processing quality.

[0041] To this end, the present invention provides a clamping-type limited workpiece laser cutting machine, see Figures 1-2 As shown, it includes a base 1 with a support 11 fixedly connected to the top, a laser cutter 12 fixedly connected between the base 1 and the outer walls on both sides of the support 11, near the end, and the laser cutter 12 is located above the support 11;

[0042] A slide groove is provided inside the support 11 near the other end, and a clamping assembly 13 is provided inside the slide groove of the support 11. The clamping assembly 13 includes two universal members 131, which are movably connected to the slide groove of the support 11 near both ends. A cylinder 130 is provided at the end of one of the universal members 131, and the cylinder 130 is fixedly connected to the slide groove of the support 11 near one end. An elastic member 132 is provided between the other universal member 131 and the slide groove of the support 11.

[0043] A groove is provided at the center of the support 11, and a smooth component 15 is provided inside the groove of the support 11. A positioning component 14 is provided between the support 11 and the outer wall of the base 1, and between the laser cutter 12 and the clamping component 13. The positioning component 14 is located at the top of the support 11. The positioning component 14 is used to clamp the workpiece stably while driving the workpiece to move.

[0044] First, the specific structure of the universal joint 131 is disclosed. The universal joint 131 includes a support column 1310, and the support column 1310 is slidably connected inside the chute of the support 11. One of the support columns 1310 is fixedly connected to the end of the piston rod of the first cylinder 130, and an elastic member 132 is provided between the other support column 1310 and the inner wall of the chute. A rotating groove 1311 is provided near the top inside the support column 1310, and a rotating ball 1313 is movably clamped inside the rotating groove 1311. The rotating ball 1313 passes through the outer wall of the rotating groove 1311 and is fixedly connected to an arc plate 1312;

[0045] Refer to Figure 3 With Figure 5 As shown, by driving the two arc plates 1312 closer through the mutual approach of the two support columns 1310, the workpiece is clamped. When the arc plate 1312 touches the workpiece, the pressure of the continuous approach of the two support columns 1310 will cause the pressure between the workpiece and the arc plate 1312 to form a counterforce. Through the reaction force of the workpiece on the arc plate 1312, the arc plate 1312 moves towards the support column 1310, causing the rotating ball 1313 at the end of the arc plate 1312 to rotate inside the rotating groove 1311, thereby adjusting the angle of the arc plate 1312;

[0046] Among them, in the processing field, if the surface of the workpiece is relatively sensitive, an elastic pad (not shown in the figure) is usually used as a lining and added inside the arc plate 1312 to protect the surface of the workpiece, enhance the clamping stability and disperse the pressure, and can also adapt to high-temperature environments, improving the durability and overall performance of the equipment.

[0047] Secondly, the specific structure of the elastic member 132 is disclosed. The elastic member 132 includes a sliding rod 1320, and the sliding rod 1320 is fixedly connected inside the chute of the support 11. The sliding rod 1320 is movably communicated inside one of the support columns 1310, and a first elastic member 1321 is provided between the support column 1310 and the inner wall of the support 11. The first elastic member 1321 is wound around the outer wall of the sliding rod 1320;

[0048] Refer to Figure 4 With Figure 6As shown in the figure, one of the struts 1310 is driven by the first cylinder 130 to approach the other strut 1310, so that the workpiece is clamped between the two struts 1310. At this time, the other strut 1310 will be driven by the extrusion force of the workpiece to stretch the first elastic member 1321 outward, and the elastic resilience of the first elastic member 1321 itself will drive the strut 1310 to contract. During the contraction process of the strut 1310, it moves on the outer wall of the slide bar 1320, and the stability of the movement of the strut 1310 is maintained by the slide bar 1320. When the two struts 1310 are in the state of approaching each other, one forms a fixed clamping force by applying pressure through the first cylinder 130 to ensure that the workpiece does not displace or shake during the processing, and the other forms a dynamic clamping force through the elastic contraction force of the first elastic member 1321, which can automatically adjust the clamping force according to the shape and size of the workpiece to avoid deformation or damage of the workpiece caused by excessive clamping force. This clamping method of combining rigidity and flexibility is particularly suitable for thin-walled or easily deformed workpieces, which can reduce local stress concentration while ensuring stability.

[0049] Further, the specific structure of the positioning component 14 is disclosed. The positioning component 14 includes lifting members 140. The two lifting members 140 are respectively fixedly connected to the outer walls of the two sides of the support 11 and the base 1. A fixing member 141 is provided between the two lifting members 140, and the fixing member 141 is located at the top of the support 11.

[0050] Refer to Figure 7 As shown in the figure, the lifting member 140 drives the fixing member 141 to move up and down. When the fixing member 141 touches the top of the workpiece, the fixing member 141 rotates to drive the workpiece to move, and drives the smooth component 15 to rotate during the movement of the workpiece, improving the moving speed and smoothness of the workpiece. When the workpiece needs to be cut, the clamping force is increased through the fixing member 141 to press and fix the workpiece on the top of the support 11. At the same time, the smooth component 15 descends so that the central part of the workpiece is stuck in the groove of the support 11, ensuring the local stability of the cutting part, effectively preventing vibration or displacement during the cutting process, and improving the cutting accuracy.

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

[0052] When the support rod 1401 moves downward, the suction cup 1411 adsorbs the top of the workpiece. The motor 1413 drives the rotating rod 1412 and the rotating cylinder 1410 to rotate. Since the suction cup 1411 is fixed to the outer wall of the rotating cylinder 1410, the suction cup 1411 will rotate together with the rotating cylinder 1410, and the thrust generated by its rotation acts on the workpiece, thereby driving the workpiece to move along the rotation direction of the rotating cylinder 1410. At the same time, the rotating rod 1511 in the smooth component 15 will rotate under the action of the friction force of the workpiece, reducing the moving resistance of the workpiece and ensuring the smooth movement of the workpiece.

[0053] Refer to Figure 7 As shown, the piston rod of the second cylinder 1400 drives the support rod 1401 to move up and down, and the two support rods 1401 drive the fixing member 141 to move up and down, assisting the fixing member 141 to clamp and position the top of the workpiece, which can achieve precise workpiece fixing and position adjustment, flexibly adjust the clamping height according to the thickness and shape of the workpiece, ensure the stability of the workpiece during the cutting process, and avoid displacement or shaking caused by vibration or external force; at the same time, the up and down movement function of the fixing member 141 enables the clamping device to quickly adapt to workpieces of different sizes, improving the versatility and operation efficiency of the equipment;

[0054] Specifically, the specific structure of the fixing member 141 is disclosed. The fixing member 141 includes a rotating rod 1412. A rotating cylinder 1410 is fixedly connected to the outer wall of the rotating rod 1412. The rotating cylinder 1410 is located between the two support rods 1401. One end of the rotating rod 1412 is provided with a motor 1413. A plurality of suction cups 1411 are fixedly connected to the outer wall of the rotating cylinder 1410;

[0055] Refer to Figure 8 As shown, when the support rod 1401 moves downward, the suction cup 1411 adsorbs and clamps the top of the workpiece, ensuring the stability of the workpiece during the cutting process and avoiding displacement or shaking caused by vibration or external force; the motor 1413 drives the rotating rod 1412 and the rotating cylinder 1410 to rotate, and the rotating thrust of the suction cup 1411 can drive the workpiece to move along the rotation direction of the rotating cylinder 1410, realizing the smooth transfer of the workpiece; the advantage of this design is that it can not only precisely fix the workpiece, but also realize the automatic movement of the workpiece during the cutting process, reducing manual intervention and improving processing efficiency; at the same time, the rotating movement mode of the suction cup 1411 can ensure the smoothness of the workpiece during movement and avoid workpiece damage caused by friction or impact, further improving the processing accuracy and workpiece integrity.

[0056] Furthermore, the specific structure of the smooth component 15 is disclosed. The smooth component 15 includes a plurality of rolling elements 151. A pressing plate 150 is fixedly connected between the plurality of rolling elements 151. Pressure members 152 are fixedly connected to the bottoms of the plurality of pressing plates 150. The pressing plate 150, the rolling elements 151 and the pressure members 152 are all movably connected inside the support 11;

[0057] Refer to Figure 9 and Figure 10 As shown, when the workpiece moves driven by the suction cup 1411, the rotation of the smooth component 15 can increase the driving force of the workpiece's advancement, reduce the driving 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 blockage or 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 component 15 can also reduce the load of the suction cup 1411, extend its service life, and improve the operating efficiency of the overall equipment; in addition, this smooth movement mode can reduce the frictional 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 a plurality of grooves of the support 11. A plurality of support plates 1510 are fixedly connected through a pressure 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 communicated inside the support plate 1510;

[0059] Refer to Figure 10 As shown, through the driving force in the moving state of the workpiece, the workpiece rubs on the surface of the rotating rod 1511 and drives a 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 supporting surface, enabling the workpiece to move more easily and smoothly, and avoiding 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 operating efficiency and service life of the equipment, and is particularly suitable for high-precision and high-efficiency laser cutting processing scenarios;

[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 to the bottom of the pressure plate 150. A clamping plate 1522 is fixedly connected to the bottom of the pressure rod 1520. Both the clamping plate 1522 and the pressure rod 1520 are movably connected inside the support 11. A second elastic member 1521 is wound around the outer wall of the pressure rod 1520, and the second elastic member 1521 is fixedly connected to the bottom of the pressure plate 150;

[0061] Refer to Figure 11As shown, when the support rod 1401 continues to move downward, increasing the clamping force of the suction cup 1411 on the top of the workpiece, the clamping and extrusion force on the workpiece will drive the multiple pressure plates 150 to move downward. When the pressure plate 150 moves downward, it will drive the pressure rod 1520 and the clamping plate 1522 to move downward. At this time, the second elastic member 1521 is contracted, so that the multiple pressure plates 150 are contracted inside the support 11, and the multiple support plates 1510 and the rotating rod 1511 are simultaneously contracted inside the support 11 through the pressure plate 150, so as to prevent the workpiece from continuing to move, and at the same time enable the workpiece to contact the groove at the center of the support 11 and be clamped on the top of the groove, thereby ensuring the stability of the workpiece during the cutting process, avoiding displacement or shaking caused by vibration or external force, and thus improving the cutting accuracy; when the workpiece is cut, the movement is stopped to maintain the stability of the workpiece in the cutting state;

[0062] Among them, the groove of the support 11 is designed to be thinner, and the workpiece will not be completely clamped inside the groove. The workpiece only provides support force through the two ends of the groove gap. This design avoids excessive pressure concentration on the surface of the workpiece; secondly, the groove is mainly used to clamp and support workpieces with an arc structure, which are inconvenient to clamp and easy to roll on the support 11. For workpieces with a relatively 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 effectively avoids deformation problems caused by clamping while ensuring the stability of the workpiece, and is particularly suitable for the processing of workpieces with complex shapes.

[0063] When the support rod 1401 moves upward and reduces the clamping pressure of the suction cup 1411, the elastic rebound force of the second elastic member 1521 will drive the pressure plate 150 and the pressure rod 1520 upward, and drive the support plate 1510 to reset upward, ensuring the smoothness of the workpiece during movement. At the same time, the moving distance of the pressure rod 1520 is limited by the clamping plate 1522, ensuring the accuracy and controllability of the workpiece movement.

[0064] In summary, by placing the workpiece between the two arc plates 1312, when the arc plates 1312 touch the workpiece, the pressure of the two pillars 1310 that is constantly approaching each other will cause the pressure between the workpiece and the arc plates 1312 to form an opposing force, and the reverse force of the workpiece on the arc plates 1312 causes the arc plates 1312 to move toward the pillars 1310, so that the rotating balls 1313 at the ends of the arc plates 1312 rotate inside the rotating grooves 1311, thereby adjusting the angles of the arc plates 1312; through the linkage between the arc plates 1312 and the elastic members 132, the workpiece is clamped and adaptively adjusted, ensuring that the surface of the workpiece is not damaged during the clamping process, while adapting to workpieces of different shapes and sizes, thereby improving the versatility and stability of the clamping device;

[0065] Secondly, through the cooperation of the first cylinder 130 and the elastic member 132, a clamping method that combines rigidity and flexibility is achieved, which not only ensures the fixing stability of the workpiece but also avoids workpiece deformation or damage caused by excessive clamping force, and is particularly suitable for the processing of thin-walled or easily deformable workpieces;

[0066] Next, through the design of the second cylinder 1400 and the suction cup 1411 in the positioning component 14, precise positioning and automatic movement of the workpiece are achieved, reducing manual intervention and improving processing efficiency; at the same time, the linkage design of the rolling member 151 and the pressure member 152 in the smooth component 15 ensures the smoothness and stability of the workpiece during movement, reducing frictional resistance and workpiece damage;

[0067] So that the workpiece can be moved separately through the positioning component 14 under the clamping action; specifically, the second cylinder 1400 drives the support 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, and the suction cup 1411 rotates accordingly and pushes the workpiece to move; during this process, the rotating rod 1511 of the smooth component 15 rotates to assist the movement of the workpiece, enabling it to move more smoothly separately;

[0068] Finally, through the limit design of the second elastic member 1521 and the clamping plate 1522 of the pressure member 152, dynamic fixing and movement control of the workpiece during cutting are achieved, ensuring cutting accuracy and workpiece integrity;

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

[0070] Working principle:

[0071] During use, the first cylinder 130 drives the two support columns 1310 to approach each other, so that the arc plate 1312 contacts the surface of the workpiece; at this time, the reaction force of the workpiece causes the arc plate 1312 to rotate in the rotating groove 1311 through the rotating beads 1313, automatically adjusting the clamping angle to ensure that the clamping device adapts to workpieces of different shapes and sizes;

[0072] At this time, a fixed clamping force is provided by the first cylinder 130 to ensure that the workpiece does not displace or shake during processing; and the elastic member 132 forms a dynamic clamping force through the elastic resilience of the first elastic member 1321, which can automatically adjust the clamping force according to the shape and size of the workpiece, avoiding workpiece deformation or damage caused by excessive clamping force; this clamping method that combines rigidity and flexibility is particularly suitable for thin-walled or easily deformable workpieces, which can reduce local stress concentration while ensuring stability;

[0073] Next, the second cylinder 1400 drives the support rod 1401 to move up and down, so that the fixing member 141 clamps and positions the top of the workpiece; the suction cup 1411 adsorbs the top of the workpiece to ensure the stability of the workpiece during cutting; the motor 1413 drives the rotating rod 1412 and the rotating cylinder 1410 to rotate, so that the suction cup 1411 pushes the workpiece to move smoothly along the direction of the rotating cylinder 1410, reducing manual intervention and improving processing efficiency;

[0074] When the workpiece moves, the rotating rod 1511 of the smooth component 15 rotates through the friction force of the workpiece, reducing the moving resistance and ensuring the smooth movement of the workpiece; when the workpiece needs to be cut, the support rod 1401 moves downward, increasing the clamping force of the suction cup 1411, so that the workpiece is clamped into the central groove of the support 11, ensuring the local stability of the cutting part, preventing vibration or displacement, and improving the cutting accuracy;

[0075] When the support rod 1401 continues to move downward, the pressing plate 150 and the pressure member 152 make the workpiece stably clamped at the top of the groove through the contraction of the second elastic member 1521, ensuring the stability during cutting; when the support rod 1401 moves upward, the elastic restoring force of the second elastic member 1521 drives the pressing plate 150 and the support plate 1510 to reset, ensuring the smoothness and accuracy of the workpiece during movement;

[0076] In addition, for longer workpieces, the stability can be ensured through the coordinated action of various structures in the present invention; on the one hand, the clamping assembly 13 cooperates with the first cylinder 130 and the elastic member 132 to flexibly clamp one end of the workpiece, and can automatically adjust the clamping force according to the shape and size of the workpiece to 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, increasing the fixing points of the workpiece. At the same time, in cooperation with the smooth component 15 and the groove in the center of the support 11, when the workpiece moves and is cut, the central part of the workpiece can be clamped into the groove to form multi-point fixation, disperse stress, and further enhance the overall stability of the workpiece. Even for longer workpieces, it can ensure their stability to a certain extent during the cutting process.
