[0018] The conventional clamping method relies on a simple clamp, and during the milling process, the workpiece often displaces and loosens, resulting in loss of control of key dimension precision such as blade thickness and angle, greatly affecting the precision and stability of the wire cutter shearing, and reducing the product qualification rate. At the same time, if the large amount of waste generated during the milling process cannot be cleaned in time, it will fall on the operation table, and with the operation of the equipment, the waste may enter the internal components of the equipment, causing equipment failure. At the same time, due to the irregularity of the components on the operation table, it is difficult to clean the waste, which easily affects the normal operation of the equipment and the working environment.
[0019] After realizing the above problems, the present application proposes and discloses a wire cutter inner and outer blade milling device, which can stably clamp the wire cutter and conveniently collect and clean the waste generated during the milling process.

[0022] As Figure 3 , Figure 4 and Figure 5 shown, the clamping unit 3 includes a bottom plate 5, a slide rail 6, a movable plate 7, a vertical plate 8, a traction rod 9, a reset spring 10 and a rotating rod 11, the bottom plate 5 is arranged on the lower wall of the inner cavity of the workbench 2, the slide rail 6 is provided with two groups, and the two groups of slide rails 6 are oppositely arranged on the two ends of the bottom plate 5, the lower wall of the movable plate 7 is provided with a sliding block 12, and the movable plate 7 is movably arranged on the slide rail 6 through the sliding block 12; The vertical plate 8 is fixedly arranged on the movable plate 7, and the vertical plate 8 is arranged close to each other, one end of one group of bridge type clamping plates 4 is fixedly arranged on the vertical plate 8 of one group of clamping units 3, and the other end of the bridge type clamping plate 4 is fixedly arranged on the corresponding vertical plate 8 of the other group of clamping units 3, one end of the other group of bridge type clamping plates 4 is fixedly arranged on the other group of vertical plates 8 of one group of clamping units 3, and the other end of the bridge type clamping plate 4 is fixedly arranged on the corresponding vertical plate 8 of the other group of clamping units 3; One end of the traction rod 9 is fixedly arranged on one group of vertical plates 8, and the other end of the traction rod 9 is movably penetrated on the other group of vertical plates 8; The reset spring 10 is sleeved on the traction rod 9, and the two ends of the reset spring 10 abut against the two groups of vertical plates 8, respectively; The rotating rod 11 is movably arranged on the bottom plate 5 through a center shaft, the rotating rod 11 is arranged between the two groups of slide rails 6, one end of the rotating rod 11 is movably connected to one group of movable plates 7, and the other end of the rotating rod 11 is movably connected to the other group of movable plates 7.

[0024] As shown in Figure 4 , Figure 5 and Figure 6 , the inner cavity of the workbench 2 is provided with two sets of hydraulic devices 13, and the two sets of hydraulic devices 13 are arranged close to the two sets of clamping units 3, respectively.

[0025] In the embodiment, when the movable end of the hydraulic device 13 extends and abuts against the striking rod 14, the movable plate 7 moves along the slide rail 6, so that the two sets of movable plates 7 of the same clamping unit 3 move close to each other, thereby driving the two sets of bridge-shaped clamping plates 4 to move close to each other to clamp and fix the broken wire pliers on the table top of the workbench 2. When the movable end of the hydraulic device 13 is retracted, the elastic reset spring 10 drives the two sets of movable plates 7 of the same clamping unit 3 to move away from each other until the other set of striking rods 14 abuts against the baffle 15, and the movable plate 7 stops moving.

[0027] In the embodiment, the waste chips generated by the broken wire pliers are dropped into the collection hopper 17 below the table top of the workbench 2 through the chip removal holes 16, and then are collected into the collection box 19. When the collection box 19 is full of waste chips, the collection box 19 can be taken out from the recovery groove 18 for cleaning.
[0028] As shown in Figure 4 , Figure 5 and Figure 8As shown, the inner wall of the collecting hopper 17 is provided with a high-pressure nozzle 20 at the upper end, the inner cavity of the workbench 2 is provided with a water tank 21, the water tank 21 is arranged close to the side wall of the inner cavity of the workbench 2, and the two ends of the water tank 21 are connected with a micro water pump 22, the output end of the micro water pump 22 is connected with a water delivery pipe 23, and the other end of the water delivery pipe 23 penetrates through the collecting hopper 17 and is connected with the high-pressure nozzle 20.
[0029] In this embodiment, the micro water pump 22 delivers the clean water in the water tank 21 to the high-pressure nozzle 20 through the water delivery pipe 23, and the high-pressure nozzle 20 sprays high-pressure water flow to flush the waste in the inner wall of the collecting hopper 17, so that the waste falls into the collecting box 19 below, avoiding the accumulation of waste in the collecting hopper 17.
[0030] As shown in Figure 1 , the workbench 2 is provided with two sets of cover plates 24, one set of cover plates 24 is arranged above the water tank 21 and the micro water pump 22, and the other set of cover plates 24 is arranged above the hydraulic device 13, which facilitates the staff to refill the water tank 21 and the normal maintenance of the equipment.
[0031] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 , the workbench 2 is provided with an auxiliary positioning unit 25, which is arranged close to the front end of the bridge-shaped clamping plate 4; The auxiliary positioning unit 25 includes a pad 26, a guide block 27, a threaded rod 28, a supporting spring 29 and a pressing plate 30, the pad 26 is fixedly arranged on the workbench 2, the guide block 27 is arranged on the pad 26 and away from the bridge-shaped clamping plate 4, the threaded rod 28 is threadedly connected with the pad 26 and arranged close to the bridge-shaped clamping plate 4, the supporting spring 29 is sleeved on the threaded rod 28, and the pressing plate 30 is provided with a wire hole 31, the pressing plate 30 is movably sleeved on the threaded rod 28 through the wire hole 31, and the lower wall of the pressing plate 30 abuts against the supporting spring 29; The front end of the pressing plate 30 is used to press the milling wire clamp, the tail end of the pressing plate 30 is fixedly provided with a guide rod 32, the guide block 27 is provided with a guide groove 33, the guide groove 33 is arranged in the same direction as the wire hole 31, and the guide rod 32 is movably arranged in the guide groove 33. The threaded rod 28 is provided with a bolt 34, and the bolt 34 is fixedly arranged on the upper wall of the pressing plate 30.
[0032] In this embodiment, when the bridge-shaped clamping plate 4 fixes the wire stripper from the side, the pressing plate 30 is pulled along the wire hole 31 to the upper side of the wire stripper, and then the bolt 34 is screwed to make the pressing plate 30 press the supporting spring 29 to shrink until the front end of the pressing plate 30 presses on the wire stripper, further assisting the positioning of the wire stripper, preventing the vibration caused by the milling process from disturbing the wire stripper and causing the milling quality to decline.
[0033] The supporting spring 29 can provide a continuous and uniform elastic pressing force on the surface of the pressing plate 30 and the wire stripper. When the wire stripper tends to move slightly due to cutting force and other factors during processing, the supporting spring 29 can automatically adjust the pressing force by its elastic deformation, always keeping the wire stripper effectively pressed, ensuring that the wire stripper remains in a fixed position during the milling process, preventing it from shifting or loosening, and ensuring the accuracy and stability of the processing.
