Description

Technical Field

[0001] This utility model relates to the technical field of waterjet cutting, and in particular to a base for fixing a waterjet cutting device. Background Technology

[0002] In the industrial processing field, waterjet cutting technology is widely used for cutting workpieces such as metals, stone, glass, and composite materials due to its advantages such as no thermal deformation, high processing accuracy, and wide applicability. Existing waterjet cutting equipment generally uses a grid plate structure for the machine tool's worktable. The grid plate, formed by the intersection of metal crossbeams and longitudinal beams into regular grid units, provides a stable load-bearing foundation for the workpiece. It can directly place conventional workpieces of different sizes (such as plates and block parts), achieving preliminary positioning before processing and preventing workpiece displacement during cutting due to lack of support. Simultaneously, the grid plate allows the high-pressure water flow, cutting debris, and water mist generated by waterjet cutting to pass smoothly through the grid gaps, preventing debris accumulation on the bottom of the workpiece or the table surface. This avoids scratching the workpiece surface, ensures the movement accuracy of the waterjet cutting head, and reduces the risk of equipment failure.

[0003] However, existing waterjet cutting equipment's grid plates have the following shortcomings in practical use: When dealing with small workpieces, due to their light weight, they are easily affected by the impact force under the high-speed waterjet, causing them to slide or flip. This necessitates the installation of a fixing device on the grid plate to secure the small workpieces. However, the grid plate, formed by the intersection of crossbeams and longitudinal beams, makes it impossible to install a fixing device to secure small workpieces. In view of this, the waterjet cutting equipment fixing device base of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a base for a waterjet cutting equipment fixing device that can be firmly installed on a grid plate to provide a mounting and fixing device.

[0005] The objective of this utility model is achieved through the following technical solution: A base for fixing a waterjet cutting equipment, used for mounting on a grid plate, comprising: For mounting on a grid plate, characterized in that it comprises: A support plate, wherein a through hole is formed at each of the four corners of the support plate; and A plurality of locking components are provided, each of which is rotatably disposed within a through hole and is used to engage with the mesh plate. Each locking component includes a shaft, a clamping jaw, a locking claw, and a screw block. The shaft is rotatably disposed on the bearing plate and has a through hole communicating with the through hole. The clamping jaw is rotatably disposed within the through hole and slidably disposed within the through hole, with both ends of the locking jaw abutting against the sides of the clamping jaw. The screw block is rotatably disposed on the shaft and one end of the screw block is screwed to the locking claw. When the screw block rotates relative to the shaft, it drives the locking claw to slide along the axial direction of the shaft, so that the locking claw pushes against the clamping jaw to clamp the mesh plate.

[0006] Optionally, the through hole has a square structure.

[0007] Optionally, the gripper includes a connecting block, an elastic element, and two top blocks. The connecting block is rotatably disposed within the through hole, and one end of each of the two top blocks is rotatably connected to both ends of the connecting block. The elastic element passes through the connecting block, and both ends of the elastic element abut against the two top blocks respectively.

[0008] Optionally, the connecting block has a circular hole, and the elastic element passes through the circular hole.

[0009] Optionally, the top block is provided with an anti-slip rubber pad.

[0010] Optionally, the claw is provided with a protrusion, and the top block is provided with a beveled surface, the protrusion and the beveled surface slidingly abutting against each other.

[0011] Optionally, the support plate has a plurality of mounting holes, which are spaced apart.

[0012] Optionally, the support plate is provided with a clearance hole, which penetrates the top and bottom surfaces of the support plate.

[0013] Optionally, a first annular groove is provided on the shaft column, and a first retaining ring is provided on the bearing plate, the first retaining ring engaging with the first annular groove.

[0014] Optionally, a second annular groove is provided on the shaft column, the first annular groove and the second annular groove are spaced apart, and a second retaining ring is provided on the screw block, the second retaining ring being engaged with the second annular groove.

[0015] Compared with the prior art, the present invention has at least the following advantages: This utility model relates to a base for a waterjet cutting equipment fixing device. Locking components are installed at the four corners of a support plate via through holes. Each locking component, based on a shaft, works in conjunction with grippers, chucks, and screw blocks to form a linked structure. Rotating the screw blocks causes the chucks to slide along the shaft's through holes, pushing the sides of the grippers closer together. Finally, the top block of the grippers clamps the crossbeams or longitudinal beams of the grid plate. The anti-slip rubber pad on the top block further enhances the clamping friction, preventing loosening. Simultaneously, the shaft can rotate relative to the support plate, causing the grippers and chucks to adjust their angles synchronously, adapting to beams in different directions on the grid plate without needing to adjust the overall position of the base. The elastic element also keeps the grippers open, facilitating quick alignment with the grid plate during installation, significantly improving installation convenience and adaptability, and ensuring the base remains stably fixed to the grid plate during waterjet cutting operations. This satisfies the installation and fixing needs of the fixing device, thereby meeting the cutting requirements of small-sized workpieces. Attached Figure Description

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0020] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] like Figures 1 to 10As shown, in one embodiment, a base 1 for fixing a waterjet cutting device is used to install on a grid plate 10. It includes a support plate 20 and several locking components. A through hole 21 is opened at each of the four corners of the support plate 20. Each locking component is rotatably disposed within its respective through hole 21, and each locking component is used to engage with the grid plate 10. Each locking component includes a shaft 30, a clamping jaw 31, a locking claw 32, and a screw block 33. The shaft 30 is rotatably disposed on the support plate 20, and a through-hole is opened on the shaft 30. Hole 300, through hole 300 communicates with through hole 21, clamp 31 is rotatably disposed in through hole 300, chuck 32 is slidably disposed in through hole 300, and the two ends of chuck 32 abut against the two sides of clamp 31 respectively, screw block 33 is rotatably disposed on shaft post 30, and one end of screw block 33 is screwed to chuck 32. When screw block 33 rotates relative to shaft post 30, screw block 33 drives chuck 32 to slide along the axial direction of shaft post 30, so that chuck 32 pushes clamp 31 to clamp grid plate 10.

[0024] It should be noted that a through hole 21 is formed at each of the four corners of the support plate 20, penetrating both the upper and lower surfaces of the support plate 20; four locking components are provided, each rotatably disposed within its respective through hole 21, with the other end of each locking component extending from the lower surface of the through hole 21. Further, the locking components include a shaft 30, a clamping jaw 31, a locking claw 32, and a screw block 33. The shaft 30 has a cylindrical structure, with one end rotatably connected to the support plate 20. A through hole 300 is formed on the shaft 30 along its axial direction, penetrating both ends of the shaft 30 axially, and the shaft 30 is coaxially aligned with the through hole 21 so that the through hole 300 and the through hole 21 are coaxially connected; one end of the clamping jaw 31 is rotatably disposed on the section of the through hole 300 near the support plate 20, and the clamping jaw 31... The other end passes through the perforation 21 and extends from the lower surface of the perforation 21; the pawl 32 tends to be C-shaped, slides within the through hole 300, and both ends of the pawl 32 abut against the sides of the clamping claw 31 respectively; the screw block 33 is rotatably mounted on the end of the shaft 30 away from the bearing plate 20 with the shaft 30 as the center, and a screw hole 330 is provided at the center of the screw block 33; a stud 320 is provided at the middle position of the side of the pawl 32 away from the clamping claw 31, and the stud 320 is screwed into the screw hole 330. When the screw block 33 is subjected to external force and rotates relative to the shaft 30, the screw block 33 will drive the two ends of the pawl 32 to slide close to the clamping claw 31 along the opening direction of the through hole 300 through the stud 320, and cause the two ends of the pawl 32 to push against the sides of the clamping claw 31, so that the two sides of the clamping claw 31 come closer to each other to clamp the crossbeam / longitudinal beam on the grid plate 10. In this way, all locking components can work together to fix the bearing plate 20 onto the grid plate 10.

[0025] like Figure 7 As shown, in one embodiment, the through hole 300 has a square structure. It should be noted that the through hole 300 has a square structure and penetrates both ends of the shaft post 30. The cross-sectional shape of the chuck 32 matches the cross-sectional shape of the through hole 300, so that when the chuck 32 slides within the through hole 300, it can only slide along the axial direction of the through hole 300 and cannot rotate. In one embodiment, the through hole 300 has a non-circular structure such as an ellipse or polygon, the main purpose of which is to ensure that the chuck 32 cannot rotate relative to the shaft post 30 during sliding.

[0026] It should be noted that, since the shaft 30 is rotatably mounted on the support plate 20, and the through hole 300 has a square structure, when the pawl 32 slides within the through hole 300, the shaft 30 can drive the pawl 32 to rotate relative to the support plate 20. Furthermore, the two sides of the pawl 31 are rotatably connected to the opposite sides of the through hole 300, so that while the shaft 30 drives the through hole 300 to rotate, the shaft 30 also synchronously drives the pawl 31 to rotate. In this way, when the shaft 30 rotates relative to the support plate 20, it can drive the pawl 32 and the pawl 31 to rotate synchronously. During the synchronous rotation, the axes of the pawl 32 and the pawl 31 remain aligned with the axis of the through hole 300. Thus, when the shaft 30 rotates relative to the support plate 20 to any position, both ends of the pawl 32 can always slide and abut against the sides of the pawl 31. Thus, during actual installation, the operator can rotate the shaft column 30 to make the clamp 31 clamp any one of the crossbeams or longitudinal beams of the grid plate 10, thereby improving the convenience and adaptability of the installation process.

[0027] like Figures 1 to 6 As shown, in one embodiment, the gripper 31 includes a connecting block 310, an elastic element 311, and two top blocks 312. The connecting block 310 is rotatably disposed in the through hole 300. One end of each of the two top blocks 312 is rotatably connected to both ends of the connecting block 310. The elastic element 311 passes through the connecting block 310, and both ends of the elastic element 311 abut against the two top blocks 312.

[0028] It should be noted that the width of the connecting block 310 is adapted to the width of the through hole 300, and a groove is formed on each of the two opposing inner sidewalls of the long side of the through hole 300. Both grooves are located at the end of the through hole 300 near the through hole 21, and the two grooves are coaxially aligned. A protruding cylinder is provided on each of the two opposing side surfaces of the connecting block 310, and both cylinders are located in the middle of the connecting block 310. When the two cylinders are fitted into the two grooves, the connecting block 310 can rotate within the through hole 300. Furthermore, one end of each of the two top blocks 312 is rotatably connected to both ends of the connecting block 310, while the other ends of each of the two top blocks 312 extend from the bottom surface of the support plate 20 through the through hole 21. Furthermore, the claw 32 has a C-shaped structure, and the spacing between the two ends of the claw 32 is consistent with the length of the connecting block 310, so that when the claw 32 slides in the through hole 300, its two sides can fit around the connecting block 310 and the two top blocks 312, so that the two sides of the claw 32 abut against the sides of the two top blocks 312 that are far apart from each other. Thus, when the screw block 33 drives the claw 32 to approach the connecting block 310, the two push tops on both sides of the claw 32 gradually slide and abut from the ends of the two top blocks 312 that are close to the connecting block 310, along the sides of the two top blocks 312 that are far apart from each other, so that the ends of the two top blocks 312 that are far away from the connecting block 310 gradually move closer to each other to clamp the grid plate 10 together.

[0029] like Figure 6 As shown, in one embodiment, the connecting block 310 has a circular hole 3100, and the elastic element 311 passes through the circular hole 3100.

[0030] It should be noted that the lower support portion protruding on the side of the connecting block 310 away from the claw 32 has a circular hole 3100 opened on the lower support portion, and the circular hole 3100 passes through the lower support portion and faces the two end faces of the two top blocks 312 respectively; while the elastic member 311 is a spring structure, the elastic member 311 passes through the circular hole 3100, and the two ends of the elastic member 311 extend from the two ends of the circular hole 3100 respectively, and abut against the side of the two top blocks 312 that are close to each other; under the elastic force of the elastic member 311 itself, the two top blocks 312 will rotate away from each other with the end of the connecting block 310 as the center, thereby keeping the two top blocks 312 in an open state and abutting against the two sides of the claw 32 respectively.

[0031] like Figures 1 to 6 As shown, in one embodiment, an anti-slip pad 3120 is provided on the top block 312.

[0032] It should be noted that an anti-slip pad 3120 is provided on the side of the two top blocks 312 that are close to each other, and both anti-slip pads 3120 are located at the end of the top block 312 that is away from the connecting block 310. When the two sides of the claw 32 push the two top blocks 312 to compress the elastic element 311, the two top blocks 312 respectively drive the two anti-slip pads 3120 to move closer to each other to clamp the grid plate 10 together, thereby increasing the friction of the two top blocks 312 clamping the crossbeam / longitudinal beam of the grid plate 10, and thus increasing the stability.

[0033] like Figures 1 to 6 As shown, in one embodiment, the claw 32 is provided with a protrusion 321, and the top block 312 is provided with a sloped surface 3121, and the protrusion 321 and the sloped surface 3121 slide against each other.

[0034] It should be noted that the claw 32 has a C-shaped structure, and the distance between its two ends is consistent with the length of the connecting block 310. One end of each of the two top blocks 312 is rotatably connected to the two ends of the connecting block 310. Under the push of the elastic member 311, the two top blocks 312 are parallel to the two ends of the claw 32. A protrusion 321 is provided on the side surface of the two ends of the claw 32 that are close to each other, so that the two protrusions 321 push the two top blocks 312 in a V-shaped structure. When the screw block 33 drives the claw 32 away from the connecting block 310, the two protrusions 321 slide from the end of the two top blocks 312 that is away from the connecting block 310, along the side surface of the two top blocks 312 that is far from each other to the other end of the two top blocks 312, so that the end of the two top blocks 312 that is away from the connecting block 310 gradually approaches each other to clamp the grid plate 10 together.

[0035] like Figure 1 , Figure 3 , Figure 9 As shown, in one embodiment, the support plate 20 has a plurality of mounting holes 22, which are spaced apart. It should be noted that the mounting holes 22 on the support plate 20, spaced apart, allow the fixing device to be connected to any one or more mounting holes 22, or multiple fixing devices to be mounted on the support plate 20 through the mounting holes 22. As shown, in another embodiment, the support plate 20 has clearance holes 23, which penetrate the top and bottom surfaces of the support plate 20. It should be noted that the clearance holes 23 are located at the center of the support plate 20 and penetrate both the top and bottom surfaces; when each fixing device is fixedly mounted on the support plate 20 through the mounting holes 22, the fixing device will fix the workpiece above the clearance hole 23. This avoids the influence of the high-speed water jet from the water jet on the support plate 20, preventing the support plate 20 and the workpiece from being cut together and damaged.

[0036] like Figure 5 , Figure 7 , Figure 10 As shown, in one embodiment, a first annular groove 301 is provided on the shaft column 30, and a first retaining ring 24 is provided on the bearing plate 20, which engages with the first annular groove 301.

[0037] It should be noted that a first annular groove 301 is provided on the outer side wall of the shaft column 30, and the first annular groove 301 is provided along the circumference of the shaft column 30, and the first annular groove 301 is located at the end of the shaft column 30 closer to the bearing plate 20; a first retaining ring 24 is provided on the bearing plate 20, and the first retaining ring 24 is adapted to the first annular groove 301; when the first retaining ring 24 is engaged with the first annular groove 301, the shaft column 30 can be rotatably mounted on the bearing plate 20 on the same axis.

[0038] like Figure 5 , Figures 7 to 8 As shown, in one embodiment, a second annular groove 302 is provided on the shaft column 30, and the first annular groove 301 and the second annular groove 302 are spaced apart. A second retaining ring 331 is provided on the screw block 33, and the second retaining ring 331 is engaged with the second annular groove 302.

[0039] It should be noted that a second annular groove 302 is also provided on the outer wall of the shaft column 30, and the second annular groove 302 is provided along the circumference of the shaft column 30, and the second annular groove 302 is located at the end of the shaft column 30 away from the bearing plate 20; a second retaining ring 331 is provided on the screw block 33, and the second retaining ring 331 is adapted to the second annular groove 302; when the second retaining ring 331 is engaged with the second annular groove 302, the screw block 33 can be rotatably mounted on the shaft column 30.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
