Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, specifically to a chuck for a laser cutting machine with an adjustment mechanism. Background Technology

[0002] As a high-precision processing equipment, laser cutting machines have been widely used in the precision processing of metal and non-metal materials. As a key component of laser cutting machines, the performance of the chuck directly affects the clamping accuracy, stability and processing efficiency of the workpiece. Traditional laser cutting machine chucks mostly adopt fixed clamping mechanisms or simple pneumatic clamping methods.

[0003] However, in actual use, large-diameter cylinders are usually used to provide sufficient clamping force, resulting in a bulky equipment structure and high energy consumption. At the same time, it is difficult to control and ensure the synchronization of multiple clamping points of multiple cylinders. This can easily lead to uneven lateral force on the workpiece due to asynchronous clamping force, affecting positioning accuracy and clamping stability. In addition, the existing chuck slider mechanism has insufficient smoothness during movement, which can cause the slider to jam and wobble during movement, affecting clamping accuracy. Furthermore, the existing laser cutting machine generates a large amount of debris, dust and other impurities during processing. These impurities can easily enter the equipment and the sliding mechanism through the chuck, accelerating the wear of equipment components and even causing equipment failure. Summary of the Invention

[0004] This invention aims to overcome the shortcomings of the prior art by providing a chuck for a laser cutting machine with an adjustment mechanism. Through the adjustment component, the clamping force of the slider can be infinitely and precisely adjusted, ensuring sufficient locking force to prevent slider displacement during processing and effectively avoiding slider deformation or increased sliding resistance due to excessive clamping force. The drive component, through the combination of a cylinder, driven gear, and lever mechanism, maintains the precision of gear transmission while effectively amplifying the cylinder's working stroke using the lever's leverage principle. This allows for a large range of slider movement to be met even with a smaller stroke cylinder. The bellows-like protective cover prevents impurities from entering the equipment's interior and the sliding mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chuck for a laser cutting machine with an adjustment mechanism, comprising:

[0006] The cutting machine body has a fixed plate fixedly installed on one side, an mounting plate fixedly installed on one side of the fixed plate, and a connecting plate fixedly installed on one side of the mounting plate. The surface of the connecting plate is provided with multiple sliders, and a first clamping mechanism and a second clamping mechanism are respectively installed on the top of the multiple sliders.

[0007] An adjustment assembly is disposed between the slider and the connecting plate. The adjustment assembly includes: a pressure plate, a pressing hole, an adjustment block, an adjustment hole, and an adjustment rod. Pressure plates are provided on both sides of the slider. The surface of the pressure plate is provided with a pressing hole. An adjustment block is provided on one side of one of the pressure plates. An adjustment hole is provided on one side of the adjustment block. An adjustment rod is provided inside the adjustment hole.

[0008] A drive assembly is disposed between the mounting plate and the slider. The drive assembly includes: a slot, a mounting rod, a cylinder, a gear ring, a driven gear, a lever, and a lever. The slider has a slot on the side near the connecting plate. Four mounting rods are fixed on one side of the mounting plate. One end of each mounting rod is rotatably connected to a cylinder. Two gear rings are rotatably connected to one side of the mounting plate. A driven gear is meshed with the outer side of each gear ring. A lever is connected to one side of the driven gear, and a lever is connected to one side of the lever.

[0009] Furthermore, the pressure plate on one side of the slider is connected to the connecting plate by bolts, and the adjustment hole on the adjustment block corresponds to the position of the extrusion hole.

[0010] Furthermore, one end of the adjusting rod extends through the adjusting hole into the extrusion hole, and a fixing hole is provided on the surface of the adjusting block. The adjusting block is connected to the connecting plate by bolts and the fixing hole.

[0011] Furthermore, the pressure plate has an inclined protrusion on one side near the slider, and the slider has grooves on both sides that cooperate with the protrusion.

[0012] Furthermore, the top of the slider is provided with an accordion cover, one end of which is connected to the first or second clamping mechanism corresponding to its position, and the other end of which is connected to one of the pressure plates.

[0013] Furthermore, both the first clamping mechanism and the second clamping mechanism are provided with two layers of rollers, and the rollers on the first clamping mechanism and the second clamping mechanism are staggered. The length of the outermost roller of the first clamping mechanism is greater than the length of the other rollers.

[0014] Furthermore, the four mounting rods are evenly distributed in a circular array, one end of the cylinder is connected to a connecting block, one side of the connecting block is rotatably connected to a pushing block, and the two opposing pushing blocks are on the same plane as one of the gear rings.

[0015] Furthermore, the outer surface of the gear ring has two symmetrically arranged connecting grooves, and the push block is connected to the connecting grooves by bolts.

[0016] Furthermore, the mounting plate has four movable slots inside that correspond to the positions of the levers, and the connecting plate has four arc-shaped slots on its surface. One end of the lever extends through the arc-shaped slots into the slots.

[0017] Furthermore, four arc-shaped protective covers are fixedly connected between the mounting plate and the connecting plate.

[0018] This invention provides a chuck for a laser cutting machine with an adjustment mechanism, which has the following advantages:

[0019] The advantages of this invention are that by adjusting the settings of the components, the clamping force of the slider can be infinitely and precisely adjusted, ensuring sufficient locking force to prevent the slider from shifting during processing, and effectively avoiding slider deformation or increased sliding resistance due to excessive clamping force. The wedge-shaped self-locking effect of the trapezoidal surface not only ensures extreme stability of clamping, but also significantly improves the smoothness of the slider during sliding, reducing frictional resistance and shaking during movement.

[0020] Secondly, by combining the cylinder, driven gear and lever mechanism in the drive assembly, the precision of gear transmission is maintained, and the lever principle of the lever is used to effectively amplify the working stroke of the cylinder, so that the needs of large-range slider movement can be met with the use of a small stroke cylinder. At the same time, the synchronous design of multiple drive points ensures the precise synchronization of the movement of each clamping mechanism, and realizes uniform and stable clamping of the raw material.

[0021] Next, by setting up the bellows protective cover, the debris and dust generated by laser processing can be effectively blocked from entering the equipment, thereby improving the equipment's operational reliability and service life under harsh working conditions. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This application provides a chuck for a laser cutting machine with an adjustment mechanism, which solves the problems of insufficient smoothness of slider mechanism movement and limited stroke and poor synchronization of direct cylinder drive in existing chucks.

[0038] By adjusting the component settings, the clamping force of the slider 4 can be infinitely finely adjusted to ensure sufficient locking force to prevent the slider 4 from shifting during processing, and to effectively avoid deformation of the slider 4 or increase in sliding resistance due to excessive clamping force. The combination of cylinder 601, driven gear 701 and lever 703 in the drive component maintains the precision of gear transmission, and the lever principle of lever 703 effectively amplifies the working stroke of cylinder 601, so that the need for a large range of movement of slider 4 can be met even with a smaller stroke cylinder 601. The bellows cover 402 effectively prevents debris and dust generated by laser processing from entering the equipment.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Reference Figure 1 , Figure 2 and Figure 5 As shown, a chuck for a laser cutting machine with an adjustment mechanism includes: a cutting machine body 1, a fixing plate 101 fixedly mounted on one side of the cutting machine body 1, a mounting plate 102 fixedly mounted on one side of the fixing plate 101, a connecting plate 103 fixedly mounted on one side of the mounting plate 102, a plurality of sliders 4 provided on the surface of the connecting plate 103, and a first clamping mechanism 5 and a second clamping mechanism 501 respectively mounted on the top of the plurality of sliders 4; and an adjustment assembly, which is located between the sliders 4 and the connecting plate 103, and includes: a pressure plate 2, a pressing hole 201, an adjustment block 3, an adjustment hole 302, and an adjustment rod 303. Pressure plates 2 are provided on both sides of the sliders 4, and pressing holes 201 are opened on the surface of the pressure plates 2. An adjustment block 3 is provided on one side of one of the pressure plates 2. An adjustment hole 302 is provided on one side of the adjustment block 3, and an adjustment rod 303 is provided inside the adjustment hole 302; and a drive assembly is provided. The drive assembly is located between the mounting plate 102 and the slider 4. The drive assembly includes: a slot 401, a mounting rod 6, a cylinder 601, a gear ring 7, a driven gear 701, a lever 702, and a lever 703. The slider 4 has a slot 401 on the side near the connecting plate 103. Four mounting rods 6 are fixed on one side of the mounting plate 102. One end of the mounting rod 6 is rotatably connected to the cylinder 601. Two gear rings 7 are rotatably connected on one side of the mounting plate 102. The driven gear 701 is meshed on the outer side of the gear rings 7. A lever 702 is connected to one side of the driven gear 701, and a lever 703 is connected to one side of the lever 702.

[0041] When clamping the raw material, multiple cylinders 601 in the drive assembly extend synchronously, causing the cylinders 601 to drive the push block 603 to move, which in turn drives the two stacked gear rings 7 to rotate synchronously, and then drives the driven gear 701 to rotate, thereby causing the lever 702 and lever 703 to rotate, and then drives the slider 4 to move through the slot 401, so that the first clamping mechanism 5 and the second clamping mechanism 501 clamp the raw material.

[0042] The pressure plate 2 has an inclined protrusion on one side near the slider 4, and the slider 4 has grooves on both sides that cooperate with the protrusion.

[0043] When installing the slider 4, the pressure plate 2 is fixed to the connecting plate 103 with bolts and positioned on one side of the slider 4 installation location. Then, the slider 4 is pressed against the pressure plate 2, and another pressure plate 2 is placed against the other side of the slider 4. Next, the adjusting block 3 is installed onto the connecting plate 103 with bolts and fixing holes 301. Then, the adjusting rod 303 is threaded through the adjusting hole 302 and extends into the pressing hole 201, causing the adjusting rod 303 to press the pressure plate 2 towards the slider 4, thus causing the trapezoidal protrusions on the two pressure plates 2 to... The protrusions and grooves are fitted into the corresponding grooves on the slider 4. Through the arrangement of the protrusions and grooves, the trapezoidal surfaces form a wedge-shaped self-locking effect. When the pressure plate 2 clamps the slider 4, the force that attempts to move the slider 4 vertically or horizontally will be resisted by the trapezoidal inclined surface, resulting in high clamping stability. It can withstand lateral forces and overturning torques, which is superior to simple planar clamping. At the same time, it can also play a guiding role. During use, the clamping force can be infinitely adjusted by rotating the adjusting rod 303 to adapt to the clamping requirements under different working conditions.

[0044] Reference Figure 4 As shown, the contact surfaces of the bump and the groove have the same angle, surface finish and symmetry, and are heat-treated to improve wear resistance. In addition, chip removal grooves are opened on the surface of the bump to prevent impurities accumulated between the bump and the groove from being pressed into the contact surface, which would not only affect the positioning accuracy, but also scratch the mating surface, like a sand grain effect.

[0045] Reference Figure 9 and Figure 13 As shown, further, the pressure plate 2 on one side of the slider 4 is connected to the connecting plate 103 by bolts, the adjustment hole 302 on the adjustment block 3 corresponds to the position of the extrusion hole 201, one end of the adjustment rod 303 extends through the adjustment hole 302 into the extrusion hole 201, the surface of the adjustment block 3 is provided with a fixing hole 301, and the adjustment block 3 is connected to the connecting plate 103 by bolts and fixing hole 301.

[0046] By rotating the adjusting rod 303, the pressure plate 2 is moved towards the slider 4, and in conjunction with another pressure plate 2, the slider 4 is fixed and limited. By adjusting the number of rotations or torque of the adjusting rod 303, the force applied by the pressure plate 2 to the slider 4 can be quantitatively controlled to prevent excessive force from affecting the sliding of the slider 4 and causing deformation, while ensuring the stability of the slider 4's movement.

[0047] Reference Figure 3 As shown, the top of the slider 4 is provided with an accordion cover 402. One end of the accordion cover 402 is connected to the first clamping mechanism 5 or the second clamping mechanism 501 corresponding to its position, and the other end of the accordion cover 402 is connected to one of the pressure plates 2.

[0048] During the clamping process of the raw material, the slider 4 drives the first clamping mechanism 5 and the second clamping mechanism 501 to move. At this time, the first clamping mechanism 5 and the second clamping mechanism 501 respectively drive one end of the bellows protective cover 402 connected to them to move, so that the bellows protective cover 402 is stretched and deformed, blocking the space between the two pressure plates 2, preventing the debris generated during the processing and production process from entering the equipment through the moving space of the slider 4, which would affect the normal operation and service life of the equipment.

[0049] Reference Figure 1 and Figure 8 As shown, both the first clamping mechanism 5 and the second clamping mechanism 501 are provided with two layers of rollers, and the rollers on the first clamping mechanism 5 and the second clamping mechanism 501 are staggered. The length of the outermost roller of the first clamping mechanism 5 is greater than the length of the other rollers, and the two rollers are grouped together and located on the same surface.

[0050] The pressure can be distributed by four sets of rollers located on different planes. At the same time, the four sets of rollers form a long channel, which can effectively constrain the raw material and prevent it from deviating, twisting or warping during the process, thus ensuring the straightness and positional accuracy of the processing.

[0051] Reference Figure 5 , Figure 6 and Figure 7 As shown, four mounting rods 6 are evenly distributed in a circular array. One end of the cylinder 601 is connected to a connecting block 602. A pushing block 603 is rotatably connected to one side of the connecting block 602. Two opposing pushing blocks 603 are on the same plane as one of the gear rings 7. Two symmetrically arranged connecting grooves 705 are opened on the outer surface of the gear ring 7, and the pushing block 603 is connected to the connecting groove 705 by bolts. The mounting plate 102 has four movable grooves 704 corresponding to the position of the lever 702. The surface of the connecting plate 103 has four arc-shaped grooves 105. One end of the lever 703 extends through the arc-shaped groove 105 into the slot 401.

[0052] When the drive slider 4 moves, four cylinders 601 are activated simultaneously, causing the cylinders 601 to drive the push block 603 to move via the connecting block 602. The push block 603 is connected to the gear ring 7, causing the gear ring 7 to rotate. The rotation of the gear ring 7 drives the driven gear 701, which meshes with it, to rotate. The rotation axis of the driven gear 701 is connected to the dial block 702, which in turn drives the dial block 702 to rotate. This causes the dial lever 703 to move within the arc groove 105, which in turn drives the slider 4 to move via the slot 401. The slider 4 then drives the first clamping mechanism 5 and the second clamping mechanism 501 to clamp and fix the raw material. Through the design of the drive components, the equipment has the characteristics of gear precision and the characteristics of the dial lever 703 converting and amplifying the cylinder stroke. The movable slot 704 provides space for the dial block 702 to move.

[0053] Reference Figure 3 As shown, four arc-shaped protective covers 104 are fixedly connected between the mounting plate 102 and the connecting plate 103, which can protect the equipment between the mounting plate 102 and the fixing plate 101.
