Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting machine tools, and particularly to a high-precision wire cutting machine tool with a fixture-assisted structure. Background Art

[0002] A wire cutting machine tool is a numerical control machining equipment that precisely cuts conductive materials through the principle of electric spark discharge. Its core feature is non-contact machining. It uses the heat energy generated by the high-frequency discharge between the electrode wire and the workpiece to erode the material, and is suitable for the manufacture of parts with complex shapes and high precision.

[0003] In the prior art, a Chinese patent with the application number CN202011614627.8 discloses a wire cutting machine tool for wire processing that can centrally collect waste materials, including a workbench, a waste material collection pipe, a waste material box, a filter screen, and a cutting fluid tank. A waste material collection pipe is arranged inside the workbench, a flipping gear is arranged inside the waste material collection pipe, and a baffle is connected to the outer surface of the flipping gear. A displacement plate is installed inside the workbench, and a displacement spring is connected between the displacement plate and the workbench. A filter screen is arranged inside the waste material collection pipe, and the lower end of the waste material collection pipe is connected to a cutting fluid tank. A sleeve is provided, and the waste materials cut by wire are discharged into the waste material box through the sleeve.

[0004] Again, in the prior art, a Chinese patent with the application number CN202510063266.9 discloses an adjustable wire cutting machine tool. The wire feeding device is arranged above the fixed box and is used for cutting the workpiece. The moving and adjusting device is arranged above the fixed box and on the side of the wire feeding device, and is used for driving the workpiece to move. The circulating device is arranged inside the fixed box and is used for cleaning and cooling the workpiece and for circulating and filtering the cutting fluid. The controller is arranged above the fixed box and is electrically connected to the wire feeding device, electrically connected to the moving and adjusting device, and electrically connected to the circulating device. The tightness of the electrode wire is adjusted by the rotation of the ring on the wire feeding device.

[0005] Again, in the prior art, a Chinese patent with the application number CN202411942318.1 discloses a vertical wire cutting machine tool, including a base. One side above the base is equipped with a motor, and one side of the output end of the motor is connected to an adjusting component for controlling the forward and reverse rotation of the motor. One side of the output end of the adjusting component is provided with a wire barrel, and the tail end of the wire barrel is provided with a tail barrel. A braking component is installed on the outer side of the tail barrel, and one side of the braking component is linked with a quick-clamping component through a push rod. A contact component is installed on the side of the base away from the motor. During the operation of the device, if a wire break occurs, the upper and lower groups of quick-clamping components will merge within a short time to clamp the wire.

[0006] Combined with the above materials, it can be seen that in the prior art, a wire cutting machine tool needs to use a fixture to clamp the workpiece during processing, and then achieve the purpose of wire cutting by moving the electrode wire or the workpiece. However, in the actual process, in order to avoid the influence of clamping on the cutting process, the fixture generally only clamps one corner of the workpiece. When encountering a plate-shaped workpiece, the unclamped position will bend due to gravity, thus affecting the accuracy of cutting processing. Summary of the Invention

[0007] The purpose of the present invention is to provide a high-precision wire cutting machine tool with a fixture-assisted structure to solve the problem of inaccurate cutting caused by insufficient clamping in the above-mentioned background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A high-precision wire cutting machine tool with a fixture-assisted structure, including a horizontally placed machine tool base. An installation frame is fixedly arranged at the rear side of the machine tool base. An upper electrode box is fixedly installed at the top of the installation frame, and a lower electrode box is fixedly installed inside the machine tool base. An electrode wire is fixedly installed between the upper electrode box and the lower electrode box, and a main nozzle is fixedly installed on the lower surface of the upper electrode box. A moving slider is installed inside the machine tool base, and two symmetrically arranged fixed fixtures are installed on the front side of the moving slider to clamp the plate body to be cut by using the fixed fixtures. A support box is fixedly installed inside the machine tool base, and a horizontally installed lifting plate is arranged above the support box. A negative pressure mechanism is arranged inside the lifting plate, and the inside of the support box is divided into a filter chamber and a purification chamber by a partition. An installation ring is arranged above the lower electrode box, and a clamping block for clamping the electrode wire is fixedly installed inside the installation ring. A shock absorption mechanism is arranged between the installation ring and the support box.

[0009] Preferably, the moving slider is slidably installed above a transverse slide rail, and the transverse slide rail is slidably connected to a longitudinal slide rail below it. The longitudinal slide rail is fixedly installed inside the machine tool base, and screw rod structures for transmission are arranged inside both the longitudinal slideway and the transverse slideway.

[0010] Preferably, a connecting rod for driving its movement is fixedly installed at the rear side of the fixed fixture, and the connecting rod is slidably connected to a guiding slide rod fixedly installed on the front side of the moving slider. A bolt structure for fixing it to the guiding slide rod is arranged at the upper end of the connecting rod.

[0011] Preferably, a telescopic cylinder is fixedly installed between the lower surface of the lifting plate and the upper surface of the support box, and the negative pressure mechanism includes through holes uniformly opened inside the lifting plate.

[0012] Preferably, a conveying hose communicated with the through holes is fixedly installed at the rear side of the lifting plate, a negative pressure pump is installed at the lower end of the conveying hose, and the air outlet of the negative pressure pump is communicated with the purification chamber.

[0013] Preferably, the shock absorbing mechanism includes a connecting spring fixedly installed between the lower surface of the mounting ring and the upper surface of the lower electrode box, and an auxiliary nozzle is fixedly installed above the mounting ring. The auxiliary nozzle has a bent structure and is aligned with the cutting position. The buoyancy block drives the mounting ring to move up and down through the connecting column, thereby changing the telescopic length of the connecting spring below the mounting ring to achieve the purpose of adjusting the elastic tension.

[0014] Preferably, a connecting column with a bent structure is fixedly mounted on the outer surface of the mounting ring, and the connecting column extends into the interior of the filter bin and forms a sliding structure with the filter bin, and a buoyancy block made of foam material is fixedly mounted on the bottom end of the connecting column.

[0015] Preferably, a suction pipe connected to the filter bin is fixedly mounted on the side of the support box, and the mounting ring is connected to the filter bin via a connecting hose.

[0016] Preferably, a filter filler is fixedly installed at a middle position inside the filter bin, and a liquid level sensor is fixedly installed on a side wall of the filter bin.

[0017] Preferably, a heat exchange pipe is installed through the filter bin, and the main body of the heat exchange pipe is located inside the purification bin, and the heat exchange pipe is a copper pipe structure as a whole.

[0018] Compared with the prior art, the invention has the following beneficial effects: the high-precision wire cutting machine tool with a fixture-assisted structure adopts a new structural design, the specific contents of which are as follows: 1. Use the fixed fixture to clamp the main body of the plate, and then drive the movable slider to move through the cooperation between the horizontal slide rail and the longitudinal slide rail, so that the fixed fixture drives the main body of the plate to move, and at the same time the electrode wire discharges to cut the main body of the plate. In this process, the push plate above the support box is used to support the part of the main body of the plate that is not clamped, so as to avoid deformation of the main body of the plate and affect the cutting accuracy; Furthermore, during the cutting process, a negative pressure pump is turned on, and the air inside the lifting plate is extracted using the negative pressure pump in conjunction with a delivery hose, thereby forming a negative pressure at the through hole position. Under the action of the negative pressure, the waste gas generated during cutting can be sucked into the purification chamber, and the chemical agents inside the purification chamber are used to react with the waste gas to achieve the purpose of purification.

[0019] 2. During the cutting process, the main nozzle is used to spray cutting fluid to lubricate the cutting position and take away the waste generated by cutting. Then, the cutting fluid collected inside the machine tool base is sucked into the filter bin through the suction pipe. The cutting fluid filtered by the filter filler is sprayed from the auxiliary nozzle above the mounting ring to flush the cutting position, achieving better lubrication and cleaning effects. Further, the clamping block inside the mounting ring is used to clamp the electrode wire, and at the same time, the connecting spring below the mounting ring pulls the mounting ring downward, thereby tightening the electrode wire, avoiding loosening and deformation of the electrode wire during use, and improving the use effect of the electrode wire; Furthermore, the mounting ring is connected to the buoyancy block through a connecting column. The buoyancy generated by the cutting fluid inside the filter chamber makes the buoyancy block move upward, thereby offsetting the elastic force of the connecting spring through buoyancy to achieve the purpose of adjusting the pulling force of the clamping block on the electrode wire (the smaller the deformation of the connecting spring, the smaller the elastic force, so as to change the position of the mounting ring to adjust the deformation of the connecting spring), and thus adjusting the buoyancy by changing the liquid level height.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figures 1 - 4 , for the purpose of clamping and cutting a workpiece in this embodiment, the following technical solutions are provided, and specifically disclosed are: a machine tool base 1 placed horizontally, an installation frame 2 fixedly arranged at the rear side of the machine tool base 1, an upper electrode box 3 fixedly installed at the top of the installation frame 2, and a lower electrode box 4 fixedly installed inside the machine tool base 1. An electrode wire 5 is fixedly installed between the upper electrode box 3 and the lower electrode box 4, and a main nozzle 301 is fixedly installed on the lower surface of the upper electrode box 3; a moving slider 8 is installed inside the machine tool base 1, and two symmetrically arranged fixed clamps 9 are installed on the front side of the moving slider 8, and the plate body 10 to be cut is clamped by the fixed clamps 9; a connecting rod 11 for driving its movement is fixedly installed at the rear side of the fixed clamp 9, and the connecting rod 11 is slidably connected to a guiding slide bar 12 fixedly installed on the front side of the moving slider 8. The moving slider 8 is slidably installed above a transverse slide rail 7, and the transverse slide rail 7 is slidably connected to a longitudinal slide rail 6 below it, and the longitudinal slide rail 6 is fixedly installed inside the machine tool base 1.

[0024] When using the device, first place the plate body 10 to be cut into the machine tool base 1, then slide the connecting rod 11 outside the guiding slide bar 12 to adjust the distance between the two fixed clamps 9, and then clamp and fix the plate body 10 with the fixed clamps 9. After clamping, turn on the upper electrode box 3 and the lower electrode box 4 to make the electrode wire 5 between the two energized. Then turn on the transverse slide rail 7 and the longitudinal slide rail 6. At this time, the transverse slide rail 7 slides on the longitudinal slide rail 6, and the moving slider 8 slides on the transverse slide rail 7, so that the fixed clamp 9 drives the plate body 10 to move in any direction on the horizontal plane, and cooperate with the discharge of the electrode wire 5 to achieve the purpose of cutting the plate body 10. During the cutting process, the main nozzle 301 below the upper electrode box 3 sprays cutting fluid, uses the cutting fluid to lubricate the cutting position, and uses the cutting fluid to take away the waste generated during cutting.

[0025] Embodiment 2: Please refer to Figures 5 - 6, in order to achieve the purpose of lifting the workpiece, the following technical solutions are provided, specifically disclosed as follows: A support box 13 is fixedly installed inside the machine tool base 1, and a horizontally installed lifting plate 14 is arranged above the support box 13. A negative pressure mechanism is arranged inside the lifting plate 14. The inside of the support box 13 is divided into a filter chamber 1301 and a purification chamber 1302 by a partition; A telescopic cylinder 15 is fixedly installed between the lower surface of the lifting plate 14 and the upper surface of the support box 13. The negative pressure mechanism includes through holes 16 uniformly opened inside the lifting plate 14. A conveying hose 17 communicating with the through holes 16 is fixedly installed at the rear side of the lifting plate 14. The lower end of the conveying hose 17 is installed with a negative pressure pump 18, and the air outlet of the negative pressure pump 18 communicates with the purification chamber 1302.

[0026] After clamping the plate body 10 with the fixed clamp 9, the unclamped part of the plate body 10 is located above the support box 13. Then, the telescopic cylinder 15 is turned on, and the telescopic cylinder 15 is used to push the lifting plate 14 upward. Finally, the upper surface of the lifting plate 14 fits the lower surface of the plate body 10 to lift the plate body 10, avoiding deformation of the unclamped part of the plate body 10 due to gravity. At the same time, the negative pressure pump 18 is turned on. Under the cooperation of the negative pressure pump 18 and the conveying hose 17, the air inside the lifting plate 14 is extracted, so that negative pressure is generated in the through holes 16 inside the lifting plate 14. Under the action of negative pressure, the surrounding air is inhaled, and the waste gas generated during cutting is also inhaled. The inhaled waste gas is transported to the purification chamber 1302, and the chemical agent in the purification chamber 1302 reacts with the waste gas to achieve the purpose of purification.

[0027] Embodiment Three: Please refer to Figures 7 - 10 , in order to achieve the purpose of clamping and pulling the electrode wire 5, the following technical solutions are provided, specifically disclosed as follows: An installation ring 19 is arranged above the lower electrode box 4. A clamping block 21 for clamping the electrode wire 5 is fixedly installed inside the installation ring 19. A shock absorption mechanism is arranged between the installation ring 19 and the support box 13. The shock absorption mechanism includes a connecting spring 22 fixedly installed between the lower surface of the installation ring 19 and the upper surface of the lower electrode box 4. An auxiliary nozzle 20 is fixedly installed above the installation ring 19. A connecting column 23 with a bent structure is fixedly installed on the outer surface of the installation ring 19. The connecting column 23 extends into the filter chamber 1301 and forms a sliding structure with the filter chamber 1301. A buoyancy block 24 made of foam is fixedly installed at the bottom end of the connecting column 23. A suction pipe 26 communicating with the filter chamber 1301 is fixedly installed on the side of the support box 13. The installation ring 19 communicates with the filter chamber 1301 through a connecting hose 25. A filter filler 27 is fixedly installed at the middle position inside the filter chamber 1301. A liquid level sensor 28 is fixedly installed on the side wall of the filter chamber 1301. A heat exchange pipe 29 is installed through the filter chamber 1301. The main body of the heat exchange pipe 29 is located inside the purification chamber 1302, and the whole heat exchange pipe 29 is made of copper pipe structure.

[0028] The cutting fluid ejected from the main nozzle 301 falls into the machine tool base 1 for collection. At the same time, the suction pipe 26 on the side of the support box 13 is opened, and the cutting fluid in the machine tool base 1 is sucked into the internal part of the filter chamber 1301 by the suction pipe 26. After the cutting fluid is filtered by the filter filler 27 in the filter chamber 1301, it is transported to the mounting ring 19 through the connecting hose 25 (the connecting hose 25 is connected to the pump body, and the pump body is used to achieve the purpose of transportation). Then, it is ejected from the auxiliary nozzle 20 above the mounting ring 19. The cutting fluid ejected from the auxiliary nozzle 20 is used to rinse the cutting position again. The clamping block 21 inside the mounting ring 19 clamps the electrode wire 5. At this time, under the elastic pulling action of the connecting spring 22, the mounting ring 19 is moved downward, so that the mounting ring 19 cooperates with the clamping block 21 to pull the electrode wire 5 downward, and the electrode wire 5 is tightened. When the characteristics of different electrode wires 5 are considered, the liquid level sensor 28 is used to detect the liquid level height inside the filter chamber 1301 (the feedback signal of the liquid level sensor 28 is used to cooperate with the pump body of the suction pipe 26 to control the liquid level height inside the filter chamber 1301). By changing the liquid level height and the buoyancy block 24, the height of the mounting ring 19 is changed (by changing the height of the mounting ring 19, the stretching length of the connecting spring 22 is adjusted. The connecting springs 22 with different stretching lengths have different elastic potential energies, so that different pulling forces can be provided for the mounting ring 19). The cutting fluid in the filter chamber 1301 flows into the heat exchange pipe 29. Since the cutting fluid contacts the cutting position, the high temperature at the cutting position heats the cutting fluid. Therefore, the heat exchange pipe 29 can transfer the heat to the purification chamber 1302, and the heated chemical liquid can react better with the waste gas.

[0029] At the same time, the relevant experimental data in the present invention are as follows: the mounting ring 19 is made of engineering plastic, the auxiliary nozzle 20 is made of aluminum alloy, the connecting column 23 is made of engineering plastic, the buoyancy block 24 is made of foam, the total mass of the mounting ring 19, the auxiliary nozzle 20, the connecting column 23 and the buoyancy block 24 is 400 - 500 g, and the designed pulling force of the connecting spring 22 is 400 g.

[0030] Experiment 1: The liquid level height in the filter chamber 1301 is 20 cm. At this time, the volume of the buoyancy block 24 immersed in the liquid level is 0.02 cm³. At this time, the buoyancy force received by the buoyancy block 24 is 1000 (density of the cutting fluid) × 10 (gravitational acceleration g) × 0.02 (drainage volume) = 200 N. Therefore, the force on the mounting ring 19 is 500 N + 400 N - 200 N = 700 N. This force is a downward acting force. Therefore, the mounting ring 19 is pulled downward by this pulling force, and the electrode wire 5 is tightened under the action of the pulling force.

[0031] Experiment 2: The liquid level height in the filtration chamber 1301 is 30 cm. At this time, the volume of the buoyancy block 24 immersed in the liquid level is 0.04 cm³. At this time, the buoyancy force received by the buoyancy block 24 is 1000 (cutting fluid density) × 10 (gravitational acceleration g) × 0.04 (drainage volume) = 400 N. Thus, the force on the mounting ring position 19 is 500 N + 400 N - 400 N = 500 N. This force is a downward acting force. Therefore, this pulling force is used to pull the mounting ring 19 downward, thereby tightening the electrode wire 5 under the action of the pulling force.

[0032] As can be seen from the above experiments, by changing the liquid level height inside the filtration chamber 1301, the pulling force of the mounting ring 19 on the electrode wire 5 can be changed, thereby achieving the purpose of adjusting the tension force (during this process, the position of the mounting ring 19 does not change), to adapt to different electrode wires 5 and different workpiece machining.

[0033] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
