[0002] The EDM machine tool is a machine tool equipment that processes metals using the principle of EDM. It uses electric spark discharge to produce corrosion on the metal surface, thereby realizing the processing of metal parts. The invention of the EDM machine tool is based on the principle of EDM. The characteristics of the EDM machine tool mainly include high precision, no restrictions on material hardness, small heat-affected zone, and the ability to process complex shapes and fine and tiny parts. When the EDM machine tool processes parts in batches, it is necessary to use a feeding device to control the feeding of parts in a cycle, so that the parts can be moved quickly for processing, improve processing efficiency, and reduce labor costs.

The middle position of the connecting component 202 is a circular structure, which is used to connect with the auxiliary block 203, so that the clamping plate 204 can be freely rotated for use; the connecting component 202 is rotatably connected with the auxiliary block 203, and a moving groove 206 is opened through the clamping plate 204, so that the fixed block component 207 can be freely displaced inside it, and two U-shaped plates are fixed on the back of the moving groove 206; a fixed block component 207 that can move freely forward and backward is inserted into the inside of the moving groove 206, and a pyramid block is provided on the inner side of the fixed block component 207 for anti-slip contact and fixation with parts, and a supporting block component 208 is fixed on the back of the fixed block component 207, and the supporting block component 208 of the T-shaped structure is made of elastic composite rubber material and is inserted between the two U-shaped plates. With the help of elasticity, the fixed block component 207 and the pyramid rod are continuously pushed to contact and fix with the parts.

[0032] In the present disclosure, Figure 4 and Figure 8 As shown, the bottom of the vertical rod structure 3 is slidably connected with the mounting member 301, and the vertical rod structure 3 can drive the top feeding assembly 1 to move horizontally to adjust the position. The mounting member 301 drives the vertical rod structure 3 to move horizontally through the motor 2 and the screw. Two fixing grooves 302 are respectively provided on both sides of the mounting member 301. The fixing groove 302 with a rectangular structure on the inside is a T-shaped structure on the outside. A connector structure 307 is inserted into the fixing groove 302 to fix the mounting member 301 and the connecting plate structure 303 together; the bottom of the mounting member 301 contacts the connecting plate structure 303, and the two sides of the connecting plate structure 303 are welded respectively. There is a wedge-shaped positioning block 304, which is clamped on the side of the mounting piece 301 to improve the positioning and connection effect. The positioning block 304 is fixed to the side of the EDM machine by bolts; two T-shaped side pieces 305 are fixed at both ends of the connecting plate structure 303, and the side pieces 305 are inserted into the two ends of the mounting piece 301 to assist in positioning and connection. The top of the connecting plate structure 303 is provided with two T-shaped guide grooves 306, and the bottom end of the connecting head structure 307 is inserted into the guide groove 306 and slides freely, so that the connecting head structure 307 can be displaced laterally to fix the mounting piece 301.

[0033] The working principle of this embodiment is as follows: when it is necessary to use an EDM machine to process parts, first control the connecting plate structure 303 to be fixed to the side of the EDM machine by bolts, then control the connecting plate structure 303 to be fixed to the side of the EDM machine by positioning blocks 304 and bolts, control the mounting member 301 to drive the top feeding assembly 1 to be installed and used together, so that the connecting head structure 307 is inserted into the side of the fixing groove 302, control the connecting head structure 307 and the limiting structure 308 to move horizontally, and the bottom end of the connecting head structure 307 is inside the guide groove 306. Slide horizontally, control the tightening of the bolts, move the limit structure 308 downward, assist in limit fixation, and then control the parts to be processed to be stacked in batches at appropriate positions. When feeding is required, control the motor to operate, so that the top feeding component 1 drives the clamping head component 2 to move together, and contact the parts through the clamping plate 204. After the clamping plate 204 contacts, it is automatically subjected to force and squeezes the push plate 205, so that the clamping plate 204 automatically tilts and fits the outside of the parts to increase the contact surface. At the same time, the support block component 208 continues to push the fixed block component with the help of elasticity. 207 and the pyramid rod are displaced, and the anti-slip contact with the outside of the parts drives the displacement of the parts. During the movement, if the parts fall, they can directly fall on the top of the force-bearing plate assembly 107. After the force-bearing plate assembly 107 is stressed, it is adaptively flipped through the shaft rod. At the same time, the flip head 106 and the pulling assembly 104 are adaptively pulled to squeeze the spring outside the guide rod 105. With the help of the elasticity of the spring, the collision force is eliminated to prevent the parts from falling directly to the ground and being damaged. Then the protective cover of the EDM machine tool is controlled to rise and open, and the top feeding assembly 1 is controlled. The parts are moved and fed, and the force plate assembly 107 contacts the EDM machine through the rubber pad. At the same time, the bottom end of the flip head 106 adaptively slides inside the T-slot to compress the spring so that the force plate assembly 107 can automatically adjust its position. When the feeding device is damaged, the bolts can be directly controlled to loosen, so that the limiting structure 308 rises, the fixation of the mounting part 301 is released, and the mounting part 301 and the top feeding assembly 1 are controlled to be disassembled. After reinstallation, the position of the mounting part 301 will not change, and there is no need for laborious correction and adjustment.
