Description

Technical Field

[0001] The utility model relates to the technical field of electric spark machines, in particular to a feeding mechanism of an electric spark machine. Background Art

[0002] EDM is a fine processing technology that uses electric sparks to etch metals. It is widely used to process parts with complex shapes or hard materials. The electric spark removes the workpiece material through its pulse discharge to achieve the purpose of precise size and micro-machining.

[0003] Despite the obvious technical advantages of EDM, there are some inconveniences in its actual operation, especially in mass production. During the machining process, a large amount of cooling water will accumulate in the working chamber of the EDM machine to flush and cool the electrode and workpiece. Although this helps to prevent overheating and improve machining quality, it brings an extra step after the workpiece is completed - draining the cooling water. The drainage process is time-consuming and may affect the continued use of the machine. What's more, the workpiece needs to be removed and replaced after each machining, which is particularly cumbersome in mass production and seriously affects production efficiency. Compared with automatic continuous production lines, EDM is not economical or efficient in batch processing.

[0004] Based on this, those skilled in the art have proposed a feeding mechanism for an electric spark machine. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a feeding mechanism for an electric spark machine.

[0006] The technical solution of the utility model is as follows: a feeding mechanism of an electric spark machine comprises two fixed frames, the two fixed frames are symmetrically arranged, the outer sides of the fixed frames are symmetrically connected to two gears, the outer sides of the gears are fixedly connected to a first rotating rod, the end of the first rotating rod away from the gear is rotatably connected to a second rotating rod, a fixed clamping plate is rotatably connected between one end of the two corresponding second rotating rods, a slot is opened on the side away from each other of the two fixed frames, two electric push rods are symmetrically fixedly connected to the top of the slot, a top plate is fixedly connected between the output ends of the two corresponding electric push rods, a tooth plate is fixedly connected to the bottom of the top plate, and the two gears are meshed with the corresponding tooth plate.

[0007] Through the above technical means, the electric push rod drives the top plate to move, and the movement of the top plate drives the tooth plate to move. When the tooth plate moves, it drives the gear to rotate, and the rotation of the gear drives the first rotating rod to rotate. When the first rotating rod rotates, it drives the second rotating rod to rotate, and the rotation of the two second rotating rods drives the fixed splint to move up and down.

[0008] As a preferred embodiment, a fixing block is fixedly connected to one side of the two fixing frames that are close to each other, and a limiting rod is fixedly connected to the top of the fixing block. The limiting rod extends to the inside of the corresponding tooth plate and is slidably connected thereto.

[0009] Through the above technical means, by setting the limit rod, a stable supporting force can be provided for the tooth plate, so that the tooth plate can maintain stable movement during the movement.

[0010] As a preferred embodiment, two sliding grooves are symmetrically opened on the side corresponding to the two fixed frames that are close to each other and located on the outer side of the tooth plate, and the inside of the sliding grooves are fixedly connected with sliding rods, and the side of the two fixed splints that are far away from each other are symmetrically fixedly connected with two sliding blocks, and the sliding blocks extend to the inside of the corresponding sliding grooves and are slidably connected with the sliding rods.

[0011] Through the above technical means, by setting the sliding block, the fixed splint can be easily moved stably to avoid shaking of the fixed splint.

[0012] As a preferred embodiment, the fixing splint is symmetrically threaded with two screw rods, the fixing splint is provided with a fixing groove inside, and one end of the screw rod extends into the inside of the fixing groove.

[0013] Through the above technical means, the screw is driven to move by twisting the screw, and the workpiece is squeezed and fixed through the movement of the screw.

[0014] As a preferred embodiment, a mounting plate is fixedly connected to the bottom of the fixing frame, and two mounting holes are symmetrically provided inside the mounting plate and outside the fixing frame.

[0015] Through the above technical means, the mechanism can be conveniently fixed on the fixed base of the machine tool through the mounting plate.

[0016] Compared with the prior art, the advantages and positive effects of the utility model are:

[0017] The utility model drives the top plate to move through the electric push rod, and the movement of the top plate drives the tooth plate to move. When the tooth plate moves, it drives the gear to rotate, and the rotation of the gear drives the first rotating rod to rotate. When the first rotating rod rotates, it drives the second rotating rod to rotate. The rotation of the two second rotating rods drives the fixed clamping plate to move up and down. In this way, when processing a large number of workpieces, the workpieces can be picked up from the cooling water and replaced, and then sent to a preset position, thereby achieving the purpose of improving work efficiency.

[0027] In summary: the electric push rod 7 drives the top plate 8 to move, and the movement of the top plate 8 drives the tooth plate 9 to move. When the tooth plate 9 moves, it drives the gear 2 to rotate. The rotation of the gear 2 drives the first rotating rod 3 to rotate. When the first rotating rod 3 rotates, it drives the second rotating rod 4 to rotate. The rotation of the two second rotating rods 4 drives the fixed splint 5 to move up and down.

[0028] like Figure 1-Figure 4 As shown, the two sides of the corresponding two fixing frames 1 that are close to each other are fixedly connected with a fixing block 10, and the top of the fixing block 10 is fixedly connected with a limiting rod 11, and the limiting rod 11 extends to the inside of the corresponding tooth plate 9 and is slidably connected thereto;

[0029] In summary: by providing the limiting rod 11, a stable supporting force can be provided for the tooth plate 9, so that the tooth plate 9 can maintain stable movement during the movement process.

[0030] like Figure 1-Figure 4 As shown, two slide grooves 12 are symmetrically provided on the side corresponding to the two fixing frames 1 close to each other and located on the outer side of the tooth plate 9, and the inside of the slide grooves 12 is fixedly connected with a slide rod 13, and the side of the two fixing splints 5 away from each other is symmetrically fixedly connected with two sliding blocks 14, and the sliding blocks 14 extend to the inside of the corresponding slide grooves 12 and are slidably connected with the slide rod 13;

[0031] In summary, by providing the sliding block 14 , the fixed clamping plate 5 can be easily moved stably, thereby preventing the fixed clamping plate 5 from shaking.

[0037] In actual use, first, the two fixing frames 1 are placed in the chassis through the mounting plate 17 and the position is adjusted. Then, the workpiece is placed in the two fixing grooves 15 and the workpiece is squeezed and fixed by the screw 16. After that, the top plate 8 is driven to move by the electric push rod 7, and the movement of the top plate 8 drives the tooth plate 9 to move.
