Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting machine auxiliary equipment, in particular to a clamping mechanism for a workbench of a small-format exchange table laser plate cutting machine. Background Art
[0002] In the application of small-format exchange table laser cutting machines, the clamping mechanism of the worktable is a key component to ensure cutting accuracy and stability.
[0003] The existing small-format exchange table laser cutting machine worktable clamping mechanism is mainly divided into two types. One is to use 8 groups of cylinders on both sides for clamping. This method arranges multiple groups of cylinders on both sides of the worktable to achieve clamping of the plate. Although it can provide strong clamping force, due to the large number of cylinders, installation and maintenance are more complicated, and the cylinders are easily damaged after long-term use, resulting in a decrease in clamping effect and affecting cutting accuracy.
[0004] The other method is to use a single larger cylinder to press the tail. This method achieves compression of the plate by setting a larger cylinder at the tail of the workbench. Although the structure is relatively simple, the cylinder is subjected to large forces and is prone to wear and failure, which will also affect the cutting accuracy. In addition, the cylinder is usually installed at the tail of the equipment, making maintenance and inspection inconvenient.
[0005] Both of the above methods have the problem of cylinder stress. After long-term use, the cylinder is easily damaged, resulting in loose clamping, which in turn affects the cutting accuracy during loading. In addition, the installation position of the cylinder makes the maintenance and inspection of the equipment difficult, increasing maintenance costs and time. Utility Model Content
[0006] The present invention aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent.
[0007] To achieve the above-mentioned purpose, the first aspect of the present invention proposes a clamping mechanism for the worktable of a small-format exchange table laser cutting machine, comprising: a bracket, a guide rail, a slider, a locking structure and a cylinder, wherein the bracket is arranged on a base at the end of the laser cutting machine; the guide rail is vertically arranged on the bracket; the slider is slidably arranged on the guide rail to push the slider to slide on the guide rail through the cylinder; the slider is fixed to the worktable of the laser cutting machine through the locking structure; the locking structure comprises a fixed limit block and a movable limit block, wherein the fixed limit block is arranged at the end of the worktable; the movable limit block is arranged on the slider; wherein a groove portion is provided on the fixed limit block, and a protrusion matching the groove portion is provided on the movable limit block.
[0008] In addition, the clamping mechanism of the workbench of the small-format exchange table laser cutting machine proposed in the present invention may also have the following additional technical features:
[0009] As a further description of the above technical solution: a mounting plate is provided on a side of the sliding block close to the workbench, and the movable limiting block is provided on the mounting plate.
[0010] As a further description of the above technical solution: a fixing plate is provided on the bracket, the cylinder is provided on the fixing plate, and the upper end of the cylinder is fixed to the connecting plate.
[0011] As a further description of the above technical solution: the workbench includes an upper workbench and a lower workbench arranged up and down, the number of the locking structures is two, and the two fixed limit blocks are respectively arranged on the upper workbench and the lower workbench, the two movable limit blocks are respectively arranged on the two sliders, and the two sliders are respectively pushed by two cylinders to clamp the upper workbench and the lower workbench respectively.
[0012] As a further description of the above technical solution: the groove portion is a symmetrical triangular groove structure, and the convex portion is a symmetrical triangular convex structure.
[0013] As a further description of the above technical solution: the movable limit block is detachably arranged on the sliding block, so as to facilitate disassembly in case of clamping failure.
[0014] As a further description of the above technical solution: detachable limit blocks are provided at the top and bottom of the guide rail to prevent the slider from sliding out of the guide rail.
[0015] The clamping mechanism of the workbench of the small-format exchange table laser cutting machine according to the utility model has the following beneficial effects:
[0016] (1) The clamping position is placed forward for easy maintenance and inspection: The installation position of the cylinder and the slider is placed forward, making maintenance and inspection more convenient. The traditional clamping mechanism usually installs the cylinder at the tail of the equipment, which requires moving a large number of parts during maintenance, increasing maintenance time and cost. The front design of the utility model allows maintenance personnel to quickly approach the cylinder and the slider, simplifying the maintenance process and saving time.
[0017] (2) Longer service life of the equipment: The cylinder is only used to drive the movement of the slider and the movable limit block, and is not used as a force-bearing component when the workbench shakes. This can avoid wear and damage to the cylinder caused by long-term force, thereby extending the service life of the cylinder. In contrast, in the clamping mechanism of traditional multiple groups of cylinders or a single large-size cylinder, the cylinder directly bears the shaking force of the workbench, which is prone to failure and affects the normal operation of the equipment.
[0018] (3) Has a greater load capacity: The slider and guide rail are the main load-bearing components and can withstand a greater load, ensuring that the workbench remains stable during the cutting process. The close fit between the slider and the guide rail can ensure horizontal and vertical stability, further improving the cutting accuracy.
[0019] (4) The guiding function of the locking structure further improves the precision and stability of clamping: the triangular structure of the fixed limit block and the movable limit block not only ensures that the cylinder is not affected by the horizontal force during the driving process, but also enables the movable limit block to accurately dock with the fixed limit block through the guiding function of the bevel, ensuring the smoothness and reliability of the clamping process and avoiding clamping failure or damage caused by uneven force on the cylinder.

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0028] The clamping mechanism of the workbench of the small-format exchange table laser cutting machine according to the embodiment of the present invention will be described below with reference to the accompanying drawings.
[0029] like Figures 1 to 3 As shown, the clamping mechanism of the workbench of the small-format exchange table laser cutting machine according to the embodiment of the present invention may include a bracket 100 , a guide rail 200 , a slider 300 , a locking structure 400 and a cylinder 500 .
[0030] The bracket 100 is arranged on the base 601 at the end of the laser cutting machine 600 , the guide rail 200 is vertically arranged on the bracket 100 , and the slider 300 is slidably arranged on the guide rail 200 .
[0031] As a possible scenario, a fixing plate 101 is provided on the bracket 100 , the cylinder 500 is provided on the fixing plate 101 , and the upper end of the cylinder 500 is fixed to the connecting plate 501 .
[0032] It should be noted that since the bracket 100 is arranged on the base 601 at the end of the laser cutting machine 600, the installation position is forward, which makes maintenance and inspection more convenient. The traditional clamping mechanism usually installs the cylinder 500 at the tail of the equipment, resulting in the need to move a large number of parts during maintenance, increasing maintenance time and cost. The front design of the utility model allows maintenance personnel to quickly approach the cylinder 500 and the slider 300, simplifying the maintenance process and saving time.
[0033] The slider 300 is fixed to the workbench 700 of the laser cutting machine 600 through a locking structure 400 . The locking structure 400 includes a fixed limiting block 410 and a movable limiting block 420 .
[0034] Among them, the fixed limit block 410 is set at the end of the workbench 700, and the movable limit block 420 is set on the slider 300. The fixed limit block 410 is provided with a groove portion 411, and the movable limit block 420 is provided with a protrusion 421 that matches the groove portion 411.
[0035] It should be noted that the push of the cylinder 500 can enable the slider 300 to drive the movable limit block 420 to move upward, so that the protrusion 421 is engaged in the groove 411 of the fixed limit block 410 .
[0036] Specifically, during operation, the system automatically pneumatically actuates the cylinder 500 after sensing that the workbench 700 has moved into position, causing the cylinder 500 to push the slider 300, thereby causing the movable limit block 420 to be pushed up and engaged in the groove portion 411. At this time, since the protrusion 421 is pushed up into the groove portion 411, the movable limit block 420, the guide rail 200, and the slider 300 can ensure that the workbench 700 does not move in the Y-axis direction (i.e., the vertical direction). At the same time, due to the cooperation between the protrusion 421 and the groove portion 411, it can also play a certain role in preventing movement in the X-axis direction (i.e., the lateral movement direction of the workbench 700). The driving wheel on one side of the workbench 700 is a V-shaped wheel, and the track is hexagonal steel, which can jointly ensure that the workbench 700 does not move in the X-axis direction.
[0037] It should be noted that the cylinder 500 is only used to drive the movement of the slider 300 and the movable limit block 420, and is not used as a force-bearing component when the workbench 700 shakes. This can avoid wear and damage to the cylinder 500 due to long-term force, thereby extending the service life of the cylinder 500. In comparison, in the traditional clamping mechanism of multiple groups of cylinders or a single large-size cylinder, the cylinder directly bears the shaking force of the workbench 700, which is prone to failure and affects the normal operation of the equipment. Therefore, the cylinder 500 in the utility model has a longer service life.
[0038] In addition, the slider 300 and the guide rail 200, as the main load-bearing components, can withstand greater loads, ensuring that the workbench 700 remains stable during the cutting process. The slider 300 and the guide rail 200 fit tightly together, which can ensure horizontal and vertical stability and further improve cutting accuracy.
[0039] In one embodiment of the present invention, the groove portion 411 is a symmetrical triangular groove structure, and the protrusion portion 421 is a symmetrical triangular protrusion structure.
[0040] It should be noted that the triangular structure of the fixed limit block 410 and the movable limit block 420 not only ensures that the cylinder 500 is not affected by horizontal forces during the driving process, but also, through the guiding effect of the bevel, enables the movable limit block 420 to accurately dock with the fixed limit block 410, thereby ensuring the smoothness and reliability of the clamping process and avoiding clamping failure or damage due to uneven force on the cylinder 500.
[0041] In one embodiment of the present invention, a mounting plate 301 is provided on a side of the slider 300 close to the workbench 700 , and the movable limiting block 420 is provided on the mounting plate 301 .
[0042] As a possible scenario, the movable limit block 420 can be detachably set on the slider 300, and can be fixed to the mounting plate 301 by bolt locking, and the mounting plate 301 can also be fixed to the slider 300 by bolt locking, so as to facilitate disassembly in case of clamping failure.
[0043] In one embodiment of the present invention, the workbench 700 includes an upper workbench 710 and a lower workbench 720 arranged one above the other. There are two locking structures 400 , and two fixed limit blocks 410 are respectively arranged on the upper workbench 710 and the lower workbench 720 .
[0044] As a possible scenario, two movable limit blocks 420 are respectively provided on the two sliders 300 , and the two sliders 300 are respectively pushed by two cylinders 500 to clamp the upper workbench 710 and the lower workbench 720 .
[0045] As another possible situation, two movable limit blocks 420 are respectively provided at the upper and lower ends of the same slider 300 , and only one cylinder 500 is needed to synchronously control the clamping action of the upper workbench 710 and the lower workbench 720 .
[0046] In one embodiment of the present invention, detachable limit blocks are provided on the top and bottom of the guide rail 200 to prevent the slider 300 from sliding out of the guide rail 200 .
[0047] It should be noted that the limit block can effectively block and limit the slider 300 , and when cleaning the slider 300 and the guide rail 200 , the relevant staff can remove the limit block and remove the slider 300 from the guide rail 200 .
[0048] In summary, the clamping mechanism of the workbench of the small-format exchange table laser cutting machine according to the embodiment of the utility model can not only provide effective clamping, but also has the advantages of easy maintenance, stronger load capacity, higher clamping precision and stability, etc.
