Description

Technical Field

[0001] This invention relates to the field of gantry milling machine technology, and more specifically to a gantry wire cutting machine with positioning function. Background Technology

[0002] A gantry milling machine is a large machine tool with a portal frame structure. It is mainly used for high-precision milling, drilling and other machining tasks. It is particularly suitable for handling large, heavy or complex workpieces. Gantry milling machines usually have five-axis linkage machining capabilities, which can realize the precision machining of complex parts. Gantry milling machines mainly include five-axis linkage vertical machining centers, five-axis linkage fixed beam gantry machining centers, gantry milling machines and gantry wire cutting machines.

[0003] In existing technologies, when processing raw materials of various sizes, gantry wire EDM machines often require measurement and positioning of the raw materials. Traditional positioning methods for gantry wire EDM machines generally use laser interferometers or spacing gauges for workpiece positioning. However, since gantry wire EDM machines use coolant during processing, when cutting raw materials requiring special processes (such as angled machining of irregularly shaped parts), the operator needs to adjust the tilt angle of the positioning workpiece after processing. At this time, because the workpiece surface is contaminated with coolant during processing, the laser of the laser interferometer will cause errors due to refraction on the liquid surface. Subsequently, the operator needs to continuously adjust the workpiece multiple times with the laser interferometer during processing, which will affect the processing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gantry wire EDM machine tool with positioning function to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A gantry wire cutting machine tool with positioning function includes a worktable. A mounting plate is fixedly installed on the top surface of the worktable, and several limiting seats are slidably connected to the top surface of the worktable. Several movable frames are arranged on the outer circular wall of the mounting plate. Mounting columns are slidably connected to the top surface of each movable frame. A receiving support head is fixedly installed on the top surface of each mounting column. An adjusting frame is slidably connected to the top surface of each movable frame. A first roller and a second roller are rotatably connected inside the adjusting frame. An adjusting plate is fixedly installed on one side of each mounting column, and the inner wall of the adjusting plate is slidably connected to the second roller. A supporting roller is rotatably connected to the bottom surface of each movable frame. A positioning seat is fixedly installed on the top surface of the mounting plate, and an air storage ring is fixedly installed inside the positioning seat. Several guide rods are fixedly installed on the top surface of the mounting plate, and a diverting air pipe is wound around the outer circular wall of each guide rod. The inner wall of the air storage ring... A negative pressure connector is fixedly installed on the circular wall surface. Several second receiving pipes are fixedly installed on the bottom surface of the air storage ring. A solenoid valve is fixedly sleeved on the outer circular wall surface of the second receiving pipe, and the inner circular wall surface of the solenoid valve is fixedly sleeved with the diversion air pipe. Several sliding seats are slidably connected to the top surface of the mounting plate. A second mounting cylinder is fixedly installed on the top surface of the sliding seat. A second sealing push head is movably sleeved on the inner circular wall surface of the second mounting cylinder. A second connecting column is fixedly installed on one side of the second sealing push head. The second connecting column is slidably connected to the second mounting cylinder. An adjusting push rod is slidably connected to the top surface of the sliding seat. One end of the second connecting column is fixedly installed with the adjusting push rod. A spacing adjustment component is provided inside the mounting plate to adjust the spacing of multiple receiving supports to accommodate raw materials of different sizes. Clamping components are provided inside several limiting seats to clamp and fix the raw materials.

[0007] By adopting the above technical solution, and using the spacing adjustment component, the spacing between multiple receiving heads can be made more spaced out to accommodate raw materials of different sizes. The worker can then place the raw material on top of the multiple receiving heads, and then slide multiple limit seats to bring them closer to the outside of the raw material. The clamping component can then clamp the raw material. After these steps are completed, the worker can perform wire cutting on the raw material. During this process, the worker can use an external negative pressure air pipe to evacuate the inside of the air storage ring to a vacuum state. Multiple solenoid valves can independently control the vacuum state inside multiple branch air pipes. The branch air pipes will then evacuate the inside of the connected second mounting cylinder to a vacuum state. At this time, under the action of air pressure, the second sealing push... The head will drive the second connecting seat to move and retract it into the second mounting cylinder. The movement of the second connecting column will then drive the adjusting push rod to move. The inclined surface on the side of the adjusting push rod will then press the adjusting frame. The second roller will slide inside the adjusting plate through the first and second rollers. Since the sliding grooves on both sides of the adjusting plate are inclined, the adjusting plate can drive the mounting column and the receiving support head to move up or down. The height of multiple receiving supports can be adjusted independently. At the same time, the clamping assembly can be adjusted at the same angle, which is convenient for the tilting processing of irregular parts. This achieves the effect of automatic angle control and positioning when the irregular parts are tilted, reducing the need for manual measurement and adjustment by the staff.

[0008] Preferably, the spacing adjustment assembly includes: an air storage hood, which is fixedly installed on the inner bottom surface of the mounting plate; a plurality of first mounting cylinders are fixedly installed inside the mounting plate; a first sealing pusher is movably sleeved inside the first mounting cylinder; a first connecting column is fixedly installed on one side of the first sealing pusher; a first receiving pipe is fixedly installed at one end of the first mounting cylinder, and the first receiving pipe extends through the interior of the air storage hood; a plurality of positioning frames are fixedly installed on the outer circular wall of the mounting plate; a plurality of connecting sleeves are slidably connected inside the positioning frames; one end of the first connecting column is fixedly installed with the connecting sleeve; one side of the connecting sleeve is fixedly installed with the movable frame; a main air pipe is fixedly installed on the top surface of the mounting plate, and the main air pipe extends into the interior of the air storage hood; and receiving rods are fixedly installed on both sides of a plurality of sliding seats, with one side of the receiving rod fixedly installed with the movable frame.

[0009] By adopting the above technical solution, by connecting the external positive pressure gas pipe to the main gas pipe, the gas storage hood and the interior of multiple first installation cylinders are filled with high-pressure gas through the delivery of positive pressure gas. Then, under the action of gas pressure, multiple first sealing push heads will drive multiple first connecting columns to move simultaneously. At this time, the moving first connecting columns will push the connecting sleeve to slide inside the positioning frame, and at the same time drive the moving frame, slide seat and adjusting push rod to slide together. This allows multiple receiving supports to move away from each other at the same time, thereby adjusting the spacing between multiple receiving supports.

[0010] Preferably, the clamping assembly includes: a plurality of positioning covers, each of which is disposed inside the limiting seat; a first adjusting post is fixedly installed on one side of each positioning cover, one end of the first adjusting post being a ball head; a first fixing sleeve is fixedly installed on one side of the limiting seat, the inner wall of the first fixing sleeve being movably sleeved with the first adjusting post; a first hydraulic cylinder is fixedly installed on the top surface of each positioning cover; a pressure plate is disposed inside the positioning cover, the top surface of the pressure plate being fixedly installed with the bottom surface of the telescopic rod of the first hydraulic cylinder; and the bottom surface of the inside of the positioning cover is fixedly... The positioning cover is equipped with a protective pad. Two second hydraulic cylinders are fixedly installed on one side of the inner side of the limiting seat. Two bearing joints are rotatably connected to one side of the positioning cover. The bearing joints are rotatably connected to one end of the telescopic rod of the second hydraulic cylinder. Two adjustment holes are opened on the top surface of the limiting seat. A third sealing push head is movably sleeved inside the adjustment hole. A second adjusting column is fixedly installed on the bottom surface of the third sealing push head. The bottom surface of the second adjusting column is a ball head. Two second fixing sleeves are fixedly installed on the top surface of the positioning cover. The inner wall surface of the second fixing sleeve is movably sleeved with the second adjusting column.

[0011] By adopting the above technical solution, the positive pressure air pipe is connected to the two adjustment holes, and the pressure plate is moved downward by the telescopic rod of the first hydraulic cylinder. Then, the positive pressure gas causes the third sealing push head to move the second adjustment column downward. At the same time, the positioning cover is deflected at an angle by the telescopic rods of the two second hydraulic cylinders. Thus, the positioning cover can be adjusted in multiple directions by the cooperation of the two second hydraulic cylinders and the two second adjustment columns.

[0012] Preferably, a first transmission seat is fixedly installed on both sides of the worktable, and a second transmission seat is provided on the top surface of the first transmission seat. Two first bearing seats are fixedly installed inside the first transmission seat, and a first lead screw is rotatably connected inside the first bearing seat. A first threaded seat is slidably connected inside the first transmission seat, and a first connecting seat is fixedly installed on the top surface of the first threaded seat. The top surface of the first connecting seat is fixedly installed with the second transmission seat. The inner circular wall surface of the first threaded seat is threadedly connected to the first lead screw. A first motor is fixedly installed on one side of the first transmission seat, and a first coupling is fixedly sleeved on the outer circular wall surface of the first motor drive shaft. The inner circular wall surface of the first coupling is fixedly sleeved with the first lead screw. A second protective cover is fixedly installed on one side of the first transmission seat.

[0013] By adopting the above technical solution, by simultaneously starting two first motors to make two first lead screws rotate at the same time, and then under the action of thread transmission, the two first thread seats will drive the second transmission seats on the top surface of the two first connecting seats to move simultaneously. In this way, the vertical displacement adjustment of the electrode wire can be achieved during the wire cutting of raw materials.

[0014] Preferably, two second bearing seats are fixedly installed inside the second transmission seat, and a second lead screw is rotatably connected inside the two second bearing seats. A second threaded seat is slidably connected inside the second transmission seat. A guide plate is fixedly installed on one side of the second threaded seat. The inner circular wall of the second threaded seat is threadedly connected to the second lead screw. A second motor is fixedly installed on one side inside the second transmission seat, and one end of the drive shaft of the second motor is fixedly installed to the second lead screw.

[0015] By adopting the above technical solution, the second motor drives the second lead screw to rotate, which in turn causes the second threaded seat to drive the wire guide plate to move laterally due to the thread transmission. This allows for the lateral position adjustment of the electrode wire during the wire cutting of raw materials.

[0016] Preferably, a third transmission seat is fixedly installed on the top surface of the second transmission seat. Two third bearing seats are fixedly installed inside the third transmission seat. A third lead screw is rotatably connected inside the two third bearing seats. A third motor is fixedly installed on one side of the third transmission seat. A second coupling is fixedly sleeved on the outer circular wall of the drive shaft of the third motor. The inner circular wall of the second coupling is fixedly sleeved with the third lead screw. A second connecting seat is slidably connected inside the third transmission seat. The inner circular wall of the second connecting seat is threadedly connected to the third lead screw. A wire cutting machining seat is fixedly installed on the top surface of the second connecting seat.

[0017] By adopting the above technical solution, when the wire cutting disc moves laterally, a third motor is used simultaneously. The drive shaft of the third motor drives the third lead screw to rotate. Then, under the action of threaded transmission, the second connecting seat drives the wire cutting processing seat on its top to move laterally together. This allows the wire cutting processing seat and the wire cutting disc to move together in linkage, thereby ensuring the accuracy of the electrode wire during use.

[0018] Preferably, a servo motor is fixedly installed on one side of the interior of the second transmission seat, a stranding roller is fixedly installed on one end of the drive shaft of the servo motor, a tensioning seat is fixedly installed on one side of the interior of the second transmission seat, a protective plate is fixedly installed on one side of the second transmission seat, and a wire box is fixedly installed on one side of the third transmission seat.

[0019] By adopting the above technical solution, the electrode wire can be placed by the simultaneous cooperation of the stranding roller, the tensioning seat and the wire box, and the tension can be ensured by the pressure roller that is elastically set inside the tensioning seat.

[0020] Preferably, a first protective cover is fixedly installed on the top surface of the workbench, and accordion protective covers are fixedly installed on the outer sides, inner sides, inner sides of the first transmission seat, and inner sides of the third transmission seat, respectively. The inner wall of the first protective cover is fixedly installed with the accordion protective cover, the two sides of the first threaded seat are fixedly installed with the accordion protective cover, the two sides of the guide plate are fixedly installed with the accordion protective cover, and the two sides of the second connecting seat are fixedly installed with the accordion protective cover.

[0021] By adopting the above technical solution, the use of the first protective cover and the bellows protective cover can prevent foreign objects from entering the bellows protective cover and prevent damage to the interior of the first transmission seat, the second transmission seat and the third transmission seat caused by dust or foreign objects. At the same time, the first protective cover can protect and shield the processing area during processing to prevent safety accidents.

[0022] In summary, the present invention has the following main beneficial effects:

[0023] 1. This invention uses multiple air pipes to evacuate the interior of the second mounting cylinder to a vacuum. Under the pressure of the air, the second sealing push head moves the second connecting seat and retracts it into the interior of the second mounting cylinder. The movement of the second connecting column then moves the adjusting push rod. The inclined surface on the side of the adjusting push rod then presses against the adjusting frame. The first and second rollers then slide the second roller inside the adjusting plate. Since the sliding grooves on both sides of the adjusting plate are inclined, the adjusting plate can move the mounting column and the receiving support head upward or downward. The height of multiple receiving supports can be independently adjusted, which is convenient for tilting of irregular parts. This achieves the effect of automatic angle control and positioning when tilting irregular parts.

[0024] 2. This invention connects an external positive pressure gas pipe to the main gas pipe, thereby filling the gas storage hood and multiple first mounting cylinders with high-pressure gas through the delivery of positive pressure gas. Then, under the action of gas pressure, multiple first sealing push heads will drive multiple first connecting columns to move simultaneously. At this time, the moving first connecting columns will push the connecting sleeve to slide inside the positioning frame, and at the same time drive the moving frame, slide seat and adjusting push rod to slide together. This allows multiple receiving supports to move away from each other at the same time, thereby adjusting the spacing between the multiple receiving supports.

[0025] 3. This invention connects the positive pressure air pipe to two adjustment holes, thereby driving the pressure plate downward through the telescopic rod of the first hydraulic cylinder. Then, the positive pressure gas causes the third sealing push head to drive the second adjustment column downward. At the same time, the telescopic rods of the two second hydraulic cylinders can cause the positioning cover to deflect at an angle. Thus, the use angle of the second sealing push head can be adjusted in multiple directions through the combined use of the two second hydraulic cylinders and the two second adjustment columns.

[0026] 4. This invention enables the simultaneous activation of two first motors to rotate two first lead screws simultaneously. Under the action of threaded transmission, the two first threaded seats will drive the second transmission seats on the top surfaces of the two first connecting seats to move simultaneously. This allows for vertical displacement adjustment of the electrode wire during wire cutting of raw materials.

[0027] 5. The present invention uses a second motor to drive a second lead screw to rotate, which in turn causes the second threaded seat to drive the wire guide plate to move laterally due to the thread transmission, thereby enabling the lateral position adjustment of the electrode wire during the wire cutting of raw materials.

[0028] 6. The present invention uses a third motor while the wire cutting disc moves laterally. The drive shaft of the third motor drives the third lead screw to rotate. Then, under the action of threaded transmission, the second connecting seat drives the wire cutting processing seat on its top to move laterally together. This allows the wire cutting processing seat and the wire cutting disc to move together in linkage, thereby ensuring the accuracy of the electrode wire during use. Attached Figure Description

A positioning seat 29 is fixedly installed on the top surface of the mounting plate 2. An air storage ring 30 is fixedly installed inside the positioning seat 29. Several guide rods 36 are fixedly installed on the top surface of the mounting plate 2. A diversion air pipe 28 is wound around the outer circular wall of the guide rods 36. A negative pressure connector 35 is fixedly installed on the inner circular wall of the air storage ring 30. Several second receiving pipes 33 are fixedly installed on the bottom surface of the air storage ring 30. A solenoid valve 34 is fixedly sleeved on the outer circular wall of the second receiving pipe 33. The inner circular wall of the solenoid valve 34 is fixedly sleeved with the diversion air pipe 28. Several sliding seats 25 are slidably connected to the top surface of the mounting plate 2. A second mounting cylinder 32 is fixedly installed on the top surface of the sliding seat 25. A second sealing push head 37 is movably sleeved on the inner circular wall of the second mounting cylinder 32. One side of the second sealing push head 37 is fixedly installed. The mounting plate 2 is equipped with a second connecting post 71, which is slidably connected to the second mounting cylinder 32. An adjusting push rod 27 is slidably connected to the top surface of the slide block 25. One end of the second connecting post 71 is fixedly installed to the adjusting push rod 27. The mounting plate 2 is internally equipped with a spacing adjustment assembly for adjusting the spacing between multiple receiving supports 19 to accommodate different sizes of raw materials. The spacing adjustment assembly includes: an air hood 12, which is fixedly installed on the inner bottom surface of the mounting plate 2. Several first mounting cylinders 11 are fixedly installed inside the mounting plate 2. A first sealing push head 16 is movably sleeved inside the first mounting cylinder 11. A first connecting post 15 is fixedly installed on one side of the first sealing push head 16. A first sealing push head 16 is fixedly installed at one end of the first mounting cylinder 11. The first receiving pipe 17 extends into the interior of the gas storage hood 12. Several positioning frames 13 are fixedly installed on the outer circular wall of the mounting plate 2. Several connecting sleeves 14 are slidably connected inside the positioning frames 13. One end of the first connecting column 15 is fixedly installed to the connecting sleeve 14, and one side of the connecting sleeve 14 is fixedly installed to the moving frame 10. A main gas pipe 31 is fixedly installed on the top surface of the mounting plate 2, extending into the interior of the gas storage hood 12. Several sliding seats 25 have receiving rods 26 fixedly installed on both sides, and one side of the receiving rods 26 is fixedly installed to the moving frame 10. By connecting the external positive pressure gas pipe to the main gas pipe 31, the gas storage hood 12 and the interior of the multiple first mounting cylinders 11 are filled with high-pressure gas through the delivery of positive pressure gas.Then, under the action of air pressure, multiple first sealing push heads 16 will drive multiple first connecting columns 15 to move simultaneously. At this time, the moving first connecting columns 15 will push the connecting sleeve 14 to slide inside the positioning frame 13, and at the same time drive the moving frame 10, slide 25 and adjusting push rod 27 to slide together. This allows multiple receiving supports 19 to move away from each other at the same time, thereby adjusting the spacing between the multiple receiving supports 19. The worktable 1 is separated from the machine tool. The worktable 1 is fixed to the foundation by eight columns and is separated from the machine tool. In this way, the size and weight of the workpiece will not affect the load-bearing capacity of the entire machine tool when processing the workpiece. Because in normal wire cutting, the larger and heavier the workpiece, the greater the load on the machine tool, and the greater the impact on precision. This is because conventional wire cutting processes the workpiece by moving the worktable 1 (the core motion is the planar movement of the worktable 1 (X, Y axis) and the reciprocating / unidirectional movement of the electrode wire. Complex processing requires coordination with the U and V axes (tapered cutting). The auxiliary motion of the Z-axis is controlled by the CNC system through programming to achieve precise cutting. This gantry type machine relies on the movement of the gantry to process the workpiece. In this way, the machine body is only responsible for the cutting motion and does not bear the load, avoiding the low precision caused by the load on the machine. This advantage becomes more and more significant with the long-term use. Each of the several limit seats 3 is equipped with a clamping component for clamping and fixing the raw material. The clamping component includes: several positioning covers 72, which are respectively set inside several limit seats 3. A first adjusting column 43 is fixedly installed on one side of the positioning cover 72. One end of the first adjusting column 43 is a ball head.

The inner wall of the second fixing sleeve 44 is movably sleeved with the second adjusting column 46. By connecting the positive pressure air pipe to the two adjusting holes 45, the pressure plate 38 can be moved downward by the telescopic rod of the first hydraulic cylinder 39. Then, the third sealing push head 47 moves the second adjusting column 46 downward by the positive pressure air. At the same time, the positioning cover 72 can be deflected at an angle by the telescopic rods of the two second hydraulic cylinders 41.Thus, the operating angle of the positioning cover 72 can be adjusted in multiple directions through the coordinated use of two second hydraulic cylinders 41 and two second adjusting columns 46.

By simultaneously starting the two first motors 54, the two first lead screws 50 rotate simultaneously. Then, under the action of threaded transmission, the two first threaded seats 51 drive the second transmission seats 5 on the top surface of the two first connecting seats 52 to move simultaneously. This allows for vertical displacement adjustment of the electrode wire during raw material wire cutting. Two second bearing seats 56 are fixedly installed inside the second transmission seat 5.

[0046] Working principle: Please refer to Figures 1-13As shown, by using the spacing adjustment component, the spacing between the multiple receiving heads 19 can be made to be far apart, adapting to raw materials of different sizes. Then, the worker can place the raw material on top of the multiple receiving heads 19, and then slide the multiple limiting seats 3 to bring them close to the outside of the raw material. Then, the raw material can be clamped by the clamping component. After the above steps are completed, the worker can perform wire cutting on the raw material. During this process, the worker can use the external negative pressure air pipe to evacuate the inside of the air storage ring 30 to a vacuum state. Then, the vacuum state inside the multiple diversion air pipes 28 can be independently controlled by multiple solenoid valves 34. Then, the diversion air pipes 28 will evacuate the inside of the connected second mounting cylinder 32 to a vacuum state. At this time, under the action of air pressure, the second sealing push head 37 will drive the second connecting column 71. The device is moved and retracted into the second mounting cylinder 32. The movement of the second connecting column 71 will drive the adjusting push rod 27 to move. Then, the inclined surface on the side of the adjusting push rod 27 will press the adjusting frame 20. Then, the first roller 21 and the second roller 22 will slide inside the adjusting plate 23. At the same time, since the sliding grooves on both sides of the adjusting plate 23 are inclined, the adjusting plate 23 can drive the mounting column 18 and the receiving head 19 to move up or down. The height of multiple receiving heads 19 can be adjusted independently. At the same time, the clamping assembly can be adjusted at the same angle, which is convenient for the tilting processing of irregular parts. This achieves the effect of automatic control of angle adjustment and positioning when the irregular parts are tilted, reducing the need for manual measurement and adjustment by the staff.
