Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for electrical discharge components, specifically to an electrode connection device for an electrical discharge machine. Background Technology

[0002] Electrical discharge machining (EDM) is a type of machining equipment mainly used for EDM parts processing. It is widely used in the manufacturing of various metal molds and mechanical equipment. EDM is a special processing method that uses the electro-erosion effect generated by pulse discharge between two electrodes immersed in a working fluid to remove conductive materials. It is also known as electrical discharge machining or electro-erosion machining.

[0003] When machining existing molds on EDM components, the installation of the electrode forming blocks used for machining the molds is inconvenient. Generally, the EDM components are set in the middle of the base to process the molds. However, when replacing the electrodes, it is difficult to move and adjust them according to the replacement requirements because the EDM components are set on one side of the base. In addition, when machining different molds or repairing different parts of the molds, the corresponding electrode forming blocks are inconvenient to replace. Utility Model Content

[0004] The purpose of this invention is to provide an electrode connection device for an EDM machine to solve the above-mentioned defects caused by the prior art.

[0005] An electrode connection device for an EDM machine includes a base, an EDM component, an electrode forming block, and a clamp. Guide rails are provided on both sides of the base, and a support is provided on the top of the base. A displacement mechanism is provided on the outer side of the support. The displacement mechanism adjusts the position of the EDM component and the electrode forming block according to the processing range of the EDM component or the electrode connection requirements. A positioning mechanism is provided on the top of the electrode forming block. The positioning mechanism assembles and disassembles the clamping spacing and the clamp according to the specifications or dimensions of the top of the electrode forming block.

[0006] Preferably, the displacement mechanism includes a guide rail, a ball screw, a bracket, an instrument seat, an EDM component, and a slide groove. One set of the guide rails has a ball screw installed inside it, and the outer sides of both sets of guide rails are connected to one side of the bracket. A slide groove is formed at the top of the bracket, and the outer side of the slide groove is connected to the instrument seat. The outer side of the instrument seat is connected to the EDM component, and the instrument seat and the EDM component are positioned directly above the base.

[0007] Preferably, the instrument seat is connected to both sides of the guide rail via a bracket on one side, and a sliding groove is connected to the outer side of the instrument seat.

[0008] Preferably, the positioning mechanism includes an electrode base, an electrode forming block, a bidirectional lead screw, a clamp, a fastener, an internal threaded rod block, and a guide block. An EDM component is connected to the top of the electrode base, and the electrode forming block is connected to the inner end of the electrode base. Clamps are provided on both sides of the electrode forming block. A fastener is connected through the outer side of the "L"-shaped clamp. Guide blocks are symmetrically provided at the bottom of the "L"-shaped clamp. The guide blocks are connected to the inner end of the electrode base via guide rods. The internal threaded rod block is located at the bottom of the clamp, and the bidirectional lead screw is connected to the inner end of the internal threaded rod. One end of the bidirectional lead screw is connected through one side of the electrode base.

[0009] Preferably, the clamp is connected to one end of the bidirectional lead screw via an internal toothed block at the bottom.

[0010] Preferably, the clamp is connected to the top of the internal toothed block by a fastener that passes through the top.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. Based on the replacement requirements of the bottom electrode forming block of the EDM component or the position of the machining mold, the longitudinal and lateral displacement operations of the EDM component are performed. The support is moved by the ball screw, and the instrument seat at the top of the support and the EDM component are used for displacement processing, so that the EDM component is moved to one side of the base, which is convenient for the operator to inspect and replace the electrode forming block of the EDM component. At the same time, the slide groove guides the outside of the instrument seat. In the actual machining process, the instrument seat is pushed and displaced by the electric cylinder, and the replacement position of the EDM component is switched according to the operating space.

[0013] 2. After the adjustment is completed, the clamps on both sides are adjusted by driving the bidirectional lead screw. The clamps are used to hold the electrode forming block on both sides. The clamping range is flexibly adjusted according to the specifications and size of the electrode forming block. At the same time, the internal toothed block is used to position and connect with the clamps, so as to facilitate the positioning of the internal toothed block with clamps of different sizes.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an electrode connection device for an EDM machine includes a base 1, an EDM component 8, an electrode forming block 10, and a clamp 13. Guide rails 2 are provided on both sides of the base 1, and a support 5 is provided on the top of the base 1. A displacement mechanism 4 is provided on the outside of the support 5. The displacement mechanism 4 adjusts the position of the EDM component 8 and the electrode forming block 10 according to the processing range of the EDM component 8 or the electrode connection requirements. A positioning mechanism 7 is provided on the top of the electrode forming block 10. The positioning mechanism 7 assembles and disassembles the clamping spacing of the positioning mechanism 7 and the clamp 13 according to the specifications or dimensions of the top of the electrode forming block 10.

[0023] In this embodiment, the displacement mechanism 4 includes a guide rail 2, a ball screw 3, a bracket 5, an instrument seat 6, an EDM component 8, and a groove 11. One set of the guide rails 2 has a ball screw 3 inside, and the outer sides of both sets of guide rails 2 are connected to one side of the bracket 5. The top of the bracket 5 has a groove 11, and the outer side of the groove 11 is connected to the instrument seat 6. The outer side of the instrument seat 6 is connected to the EDM component 8. The instrument seat 6 and the EDM component 8 are located directly above the base 1. The ball screw 3 is used to longitudinally displace the instrument seat 6, reducing the difficulty of replacing and disassembling the EDM component 8 on the instrument seat 6.

[0024] In this embodiment, the instrument seat 6 is connected to both sides of the guide rail 2 via a bracket 5 on one side. The outer side of the instrument seat 6 is connected to a sliding groove 11. The bracket 5 is used to move the instrument seat 6 on the outer side of the guide rail 2, and the sliding groove 11 at the top of the instrument seat 6 guides the instrument seat 6.

[0025] In this embodiment, the positioning mechanism 7 includes an electrode base 9, an electrode forming block 10, a bidirectional lead screw 12, a clamp 13, a fastener 14, an internal threaded block 15, and a guide block 16. An EDM component 8 is connected to the top of the electrode base 9, and the electrode forming block 10 is connected to the inner end of the electrode base 9. Clamps 13 are provided on both sides of the electrode forming block 10. Fasteners 14 are connected through the outer side of the "L"-shaped clamps 13, and guide blocks 16 are symmetrically arranged at the bottom end of the "L"-shaped clamps 13. The guide block 16 is connected to the inner end of the electrode seat 9 via a guide rod. The inner toothed block 15 is set at the bottom end of the clamp 13. The inner end of the inner toothed block 15 is connected to a bidirectional lead screw 12. One end of the bidirectional lead screw 12 is connected to one side of the electrode seat 9. The bidirectional lead screw 12 drives two sets of clamps 13 in the shape of an "L" and an inverted "L" to perform displacement processing. Then, the top end of the rectangular electrode forming block 10 is clamped by the two sets of clamps 13 to ensure the convenience of the top end of the electrode forming block 10.

[0026] In this embodiment, the clamp 13 is connected to one end of the bidirectional lead screw 12 via an inner toothed block 15 at the bottom. The clamp 13 is bolted to the inner toothed block 15. According to the usage requirements, clamps 13 of different sizes are installed on the top of the inner toothed block 15.

[0027] In this embodiment, the clamp 13 is connected to the top of the internal toothed block 15 by a fastener 14 that passes through the top. The fastener 14 passes through the top of the clamp 13, and the internal toothed block 15 drives the clamp 13 to perform displacement adjustment.

[0028] In practical applications, this electrode connection device for EDM includes the following functions:

[0029] Step 1: The operator first connects the guide rail 2 to the base 1. One set of guide rail 2 is connected to one side of the bracket 5 through the internal ball screw 3, and the other set of guide rail 2 is connected to one side of the bracket 5 through the internal slide rod, thus completing the top of the bracket 5. During use, the bracket 5 is moved to the outside of the base 1 by the ball screw 3, and the bracket 5 and the instrument seat 6 are moved longitudinally. Normally, the instrument seat 6 and the EDM component 8 can be dynamically moved according to the processing position of the mold.

[0030] Step 2: When it is necessary to replace the bottom electrode base 9 and bottom electrode forming block 10 of the EDM component 8, the instrument seat 6 connected to the bracket 5 is displaced by the electric cylinder. The instrument seat 6 drives the EDM component 8 to move laterally. At the same time, the instrument seat 6 slides on the outside of the slide groove 11, which makes it easy to move the EDM component 8 to one side of the base 1, so that the operator can disassemble the electrode forming block 10 and the instrument seat 6.

[0031] Step 3: The operator rotates the bidirectional lead screw 12 in the opposite direction. When the bidirectional lead screw 12 rotates, the corresponding nuts will move relative to each other due to the opposite direction of the threads. This causes the two sets of internal threaded blocks 15 and clamps 13 to move, increasing the distance between the two sets of clamps 13. Using the clamps 13 on both sides, the operator can release the clamps on both sides of the electrode forming block 10 and remove the electrode forming block 10 from the inside of the electrode base 9.

[0032] Step 4: When it is necessary to replace the electrode forming block 10 of a different specification, loosen the fastener 14 from the inner toothed block 15 and the clamp 13, then connect the new clamp 13 to the inner toothed block 15, and then rotate the bidirectional lead screw 12 in the positive direction to displace the two sets of inner toothed blocks 15 and clamps 13, reduce the distance between the two sets of clamps 13, and use the clamps 13 to clamp the electrode forming block 10 at four positions to ensure the stability of the electrode forming block 10 clamping.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
