Description

Technical Field

[0001] This application relates to stone processing equipment, and more particularly to a workbench positioning structure and a water saw composite processing center. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. The sheet metal is typically positioned on the worktable of a bridge cutting machine by manually nailing nails. This method is cumbersome and inaccurate, making it unsuitable for waterjet cutting. Summary of the Invention

[0003] In view of this, this application provides a workbench positioning structure and a water saw composite machining center, which can improve the positioning efficiency and accuracy of sheet metal.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A workbench positioning structure, characterized in that: it includes a machine base, a platform plate rotatably connected to the machine base for placing a sheet material, and a rotating mechanism mounted on the machine base for driving the platform plate to rotate; the platform plate, driven by the rotating mechanism, has a first state of rotating upward about a rotation axis to receive the sheet material and a second state of resetting downward about a rotation axis to a horizontal position; the front end of the platform plate is provided with a first positioning component for supporting the front side of the sheet material; the first positioning component includes a first main block detachably and fixedly mounted on the platform plate, a first adjusting block connected to the first main block in a position adjustable along the front-rear direction, and a first contact block fixedly mounted on the rear side of the first adjusting block for supporting the front side of the sheet material; the left and right sides of the platform plate are provided with second positioning components for supporting the left and right sides of the sheet material.

[0006] The workbench positioning structure described in this application can position the board material from the front and left / right sides by setting a first positioning component and a second positioning component on the platform plate, thereby ensuring the accuracy of the board material positioning. Moreover, the position of the first adjusting block relative to the first main block is adjustable, which can improve the flexibility and applicability of the positioning component. Furthermore, the first main block is detachable and can be removed during the later processing of the board material, which can reduce damage to the processing equipment.

[0007] In some embodiments, a pad is fixedly mounted on the front side rod of the platform plate, and a kit is fixedly mounted on the pad. A downwardly extending connecting post is fixedly mounted on the first main block. The kit is provided with holes for inserting the connecting post. Two limiting screws that are spaced apart from each other and extend downward are also threadedly connected to the bottom of the first main block. The screw heads of the two limiting screws abut against the pad to ensure that the first main block is at a set height position. The sidewalls of the two limiting screws engage with the side of the front side rod of the platform plate to restrict the rotation of the connecting post of the first main block relative to the kit.

[0008] The first main block can be pulled out of the kit by pulling it upwards. To prevent the first main block from rotating, two limit screws are set to restrict its rotation. Moreover, the height of the first main block can be adjusted by adjusting the height of the limit screws, thereby improving the flexibility of the positioning component.

[0009] In some embodiments, at least two first screws, spaced apart from each other, are threaded onto the first main block. These first screws extend in a front-to-back direction, with their heads pressing against a first adjusting block. The first adjusting block is locked to the first main block by a second screw extending in the front-to-back direction. The first adjusting block has a hole for the second screw to pass through, and the second screw is threadedly connected to the first adjusting block. A first contact block is also fixedly mounted on the first adjusting block by screws. By unscrewing the second screw and adjusting the extension length of the first screw's head, the relative front-to-back position of the first adjusting block can be adjusted, thereby adjusting the position of the first contact block. These adjustments ensure positioning accuracy.

[0010] In some embodiments, the second positioning component includes a positioning base fixedly connected to the platform plate, a rotating arm rotatably connected to the positioning base, and a second contact block fixedly mounted on the rotating arm. When the rotating arm rotates to one side, the rotating arm abuts against the top of the platform plate, and the direction facing the second contact block is perpendicular to the direction facing the first contact block. When the rotating arm rotates to the other side, the rotating arm rotates downward to the side of the platform plate. The rotating arm is stored by flipping, making operation simpler and more convenient.

[0011] In some embodiments, at least two third screws, spaced apart front to back, are threaded onto the rotating arm. These third screws extend laterally, with their heads abutting against a second contact block. The second contact block is locked to the rotating arm by a fourth screw, which has a hole for the fourth screw to pass through. The fourth screw is threaded into the rotating arm. The relative left and right positions of the second contact block can be adjusted by changing the extension length of the third screw's head. The first and second contact blocks are made of a material with lower hardness than the sheet metal to avoid damaging the sheet metal.

[0012] In some embodiments, a T-shaped groove extending in the front-to-back direction is also fixedly provided on the platform plate. The positioning base is fixedly mounted on the T-block by a fifth screw. The T-block is slidably mounted in the T-shaped groove, and the T-block can be fixed in the T-shaped groove by tightening the fifth screw. The T-block and T-shaped groove are mainly used to facilitate the adjustment of the front-to-back installation position of the second positioning component, and to facilitate installation and subsequent maintenance.

[0013] In some embodiments, a receiving cavity is provided in the middle of the machine, and a water tank is provided inside the receiving cavity. The water tank is provided with a lifting hole, and the platform plate is located above the water tank. When the platform plate rotates upward about the rotation axis, the water tank can be lifted out of the receiving cavity. The water tank is mainly used to collect the water flow during water jet cutting. When the water tank needs to be cleaned, it can be opened by rotating the platform plate and then lifted by a hoisting device for cleaning.

[0014] In some embodiments, there are two rotating mechanisms, located on the left and right sides of the platform plate. Each rotating mechanism includes a first connecting rod, a second connecting rod, and a drive cylinder. The upper end of the first connecting rod is hinged to the front end of the platform plate, and the lower end of the first connecting rod is hinged to the machine tool via a rotating shaft. The upper end of the second connecting rod is hinged to the rear end of the platform plate, and the lower end of the second connecting rod is hinged to the rotating shaft. The drive cylinder is mounted on the machine tool, and its extension rod is hinged to the middle of the second connecting rod. When the drive cylinder extends, the platform plate rotates around the rotating shaft via the first and second connecting rods, causing the rear end of the platform plate to tilt upwards.

[0015] This application also provides a water saw composite machining center with the above-mentioned workbench positioning structure, characterized in that: it further includes a frame and a machining mechanism, the frame including side beams located on the left and right sides of the machine table, the machining mechanism including a crossbeam slidably connected to the two side beams in the front-back direction, a front-back drive mechanism for driving the crossbeam to move back and forth, a mounting frame slidably connected to the crossbeam in the left-right direction, a left-right drive mechanism for driving the mounting frame to move left and right, a machining device slidably connected to the mounting frame in the up-down direction, and an up-down drive mechanism for driving the machining device to move up and down, the machining device including a water jet structure for water jet cutting and a sawing structure for saw blade cutting.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0017] The workbench positioning structure described in this application can position the board material from the front and left / right sides by setting a first positioning component and a second positioning component on the platform plate, thereby ensuring the accuracy of the board material positioning. Moreover, the position of the first adjusting block relative to the first main block is adjustable, which can improve the flexibility and applicability of the positioning component. Furthermore, the first main block is detachable and can be removed during the later processing of the board material, which can reduce damage to the processing equipment. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0027] See Figures 1 to 7 This application provides a water saw composite machining center including a workbench positioning structure, a frame, and a machining mechanism 8. The frame includes side beams 7 located on the left and right sides of the workbench positioning structure. The machining mechanism 8 includes a crossbeam 81 slidably connected to the two side beams 7 in the front-back direction, a front-back drive mechanism for driving the crossbeam 81 to move back and forth, a mounting frame 82 slidably connected to the crossbeam 81 in the left-right direction, a left-right drive mechanism for driving the mounting frame 82 to move left and right, a machining device slidably connected to the mounting frame 82 in the up-down direction, and an up-down drive mechanism for driving the machining device to move up and down. The machining device includes a water jet structure 83 for water jet cutting and a sawing structure 84 for saw blade cutting.

[0028] The workbench positioning structure includes a machine base 1, a platform plate 2 rotatably connected to the machine base 1 for placing the sheet metal, and a rotating mechanism 3 installed on the machine base 1 for driving the platform plate 2 to rotate. Under the drive of the rotating mechanism 3, the platform plate 2 has a first state of rotating upward around the rotating axis 34 to receive the sheet metal and a second state of resetting downward around the rotating axis 34 to a horizontal position. The front end of the platform plate 2 is provided with a first positioning component 4 for supporting the front side of the sheet metal. The first positioning component 4 includes a first main block 41 detachably and fixedly installed on the platform plate 2, a first adjusting block 42 connected to the first main block 41 in a position adjustable along the front-back direction, and a first contact block 43 fixedly installed on the rear side of the first adjusting block 42 for supporting the front side of the sheet metal. The left and right sides of the platform plate 2 are provided with second positioning components 5 for supporting the left and right sides of the sheet metal.

[0029] The workbench positioning structure, by setting the first positioning component 4 and the second positioning component 5 on the platform plate 2, can position the board on the front and left and right sides, thereby ensuring the accuracy of the board positioning. Moreover, the position of the first adjusting block 42 relative to the first main block 41 is adjustable, which can improve the flexibility and applicability of the positioning component. Furthermore, the first main block 41 is detachable and can be removed during the later processing of the board, which can reduce damage to the processing equipment.

[0030] A pad 44 is fixedly installed on the front rod 21 of the platform plate 2. A kit 45 is fixedly installed on the pad 44. A downwardly extending connecting post 46 is fixedly installed on the first main block 41. The kit 45 is provided with holes for inserting the connecting post 46. Two limiting screws 47, which are spaced apart and extend downward, are also threaded to the bottom of the first main block 41. The screw heads of the two limiting screws 47 press against the pad 44 to ensure that the first main block 41 is at a set height position. The sidewalls of the two limiting screws 47 are engaged with the side of the front rod 21 of the platform plate 2 to restrict the rotation of the connecting post 46 of the first main block 41 relative to the kit 45.

[0031] The first main block 41 can be pulled out of the kit 45 by pulling it upward. To prevent the first main block 41 from rotating, two limit screws are set to limit its rotation. Moreover, the height of the first main block 41 can be adjusted by adjusting the height of the limit screw 47, thereby improving the flexibility of the positioning component.

[0032] At least two first screws 48, spaced apart from each other, are threaded onto the first main block 41. The first screws 48 extend in the front-to-back direction and their heads press against the first adjusting block 42. The first adjusting block 42 is locked to the first main block 41 by a second screw 49 extending in the front-to-back direction.

The first contact block 43 is also fixedly mounted on the first adjusting block 42 by screws.

[0033] By unscrewing the second screw 49 and adjusting the extension length of the first screw 48, the relative position of the first adjusting block 42 can be adjusted, thereby adjusting the position of the first contact block 43. These adjustments ensure positioning accuracy.

[0034] The second positioning component 5 includes a positioning base 51 fixedly connected to the platform plate 2, a rotating arm 52 rotatably connected to the positioning base 51, and a second contact block 53 fixedly installed on the rotating arm 52. When the rotating arm 52 rotates to one side, it rests against the top of the platform plate 2, and the direction facing the second contact block 53 is perpendicular to the direction facing the first contact block 43. When the rotating arm 52 rotates to the other side, it rotates downward to the side of the platform plate 2. The rotating arm 52 is stored by flipping, making operation simpler and more convenient.

[0035] At least two third screws 54, spaced apart front to back, are threaded onto the rotating arm 52. The third screws 54 extend laterally, with their heads pressing against the second contact block 53. The second contact block 53 is locked to the rotating arm 52 by a fourth screw 55, which has a hole for the fourth screw 55 to pass through. The fourth screw 55 is threaded onto the rotating arm 52. The relative left and right positions of the second contact block 53 can be adjusted by changing the extension length of the third screw 54. The first contact block 43 and the second contact block 53 are made of a material with lower hardness than the sheet metal to avoid damaging the sheet metal.

[0036] The platform plate 2 is also fixedly provided with a T-shaped groove 56 extending in the front-to-back direction. The positioning base 51 is fixedly installed on the T-shaped block 57 by a fifth screw. The T-shaped block 57 is slidably installed in the T-shaped groove 56, and the T-shaped block 57 can be fixed in the T-shaped groove 56 by tightening the fifth screw. The T-shaped block 57 and the T-shaped groove 56 are mainly used to facilitate the adjustment of the front-to-back installation position of the second positioning component 5, and to facilitate installation and subsequent maintenance.

[0037] The machine base 1 has a receiving cavity 11 in the middle, and a water tank 6 is installed inside the receiving cavity 11. The water tank 6 has a lifting hole 61. The platform plate 2 is located above the water tank 6. When the platform plate 2 rotates upward around the rotating shaft 34, the water tank 6 can be lifted out of the receiving cavity 11. The water tank 6 is mainly used to collect the water flow during water jet cutting. When the water tank 6 needs to be cleaned, it can be opened by rotating the platform plate 2 and then lifted by the hoisting equipment for cleaning.

[0038] There are two rotating mechanisms 3, which are respectively located on the left and right sides of the platform plate 2. The rotating mechanism 3 includes a first connecting rod 31, a second connecting rod 32, and a driving cylinder 33. The upper end of the first connecting rod 31 is hinged to the front end of the platform plate 2, and the lower end of the first connecting rod 31 is hinged to the machine base 1 through the rotating shaft 34. The upper end of the second connecting rod 32 is hinged to the rear end of the platform plate 2, and the lower end of the second connecting rod 32 is hinged to the rotating shaft 34. The driving cylinder 33 is mounted on the machine base 1, and the extension rod of the driving cylinder 33 is hinged to the middle position of the second connecting rod 32. When the driving cylinder 33 extends, the platform plate 2 rotates around the rotating shaft 34 through the first connecting rod 31 and the second connecting rod 32, thereby causing the rear end of the platform plate 2 to tilt upward.

[0039] The following is a brief description of the working process and usage method of a workbench positioning structure according to the above embodiments:

[0040] First, the hydraulic cylinder 33 extends, pushing the platform plate 2 to flip, inserting the connecting post 46 on the first positioning component 4 into the hole of the kit 45. The rotating arm 52 of the second positioning component 5 rotates upward and abuts against the platform plate 2, hoisting the plate onto the platform plate 2, so that the front end of the plate abuts against the first contact block 43 of the first positioning component 4, and the left side of the plate abuts against the second contact block 53 of the second positioning component 5. The hydraulic cylinder 33 retracts, and the platform plate 2 returns to a horizontal state. Then, the first positioning component 4 is removed, and the rotating arm 52 of the second positioning component 5 is rotated to the side of the horizontal plate. The processing mechanism 8 is started to process the plate until processing is completed.
