Description

Technical Field

[0001] This utility model relates to the field of electrode wire production equipment, and in particular to a fixture for assisting in the appearance inspection of electrode wires. Background Technology

[0002] Electrical discharge machining (EDM) has developed rapidly in recent years as a special precision machining technology. In particular, slow wire EDM has become an indispensable processing method in the mold manufacturing and metal processing industries. The development of wire EDM technology is inseparable from the synchronous development of electrode wire technology, because the cutting efficiency and cutting quality of wire EDM machines are closely related to the performance of electrode wires. Breakthroughs in electrode wire technology often lead to innovations in wire EDM machine design. During the production process of electrode wires, it is necessary to detect surface damage of the electrode wires.

[0003] After electrode wires are manufactured, knots may occur, which can affect their conductivity. Therefore, visual inspection is necessary. Often, this is done by hand, but for longer electrode wires, this is inconvenient and can easily damage them. For example, utility model CN220626365U discloses a surface damage detection device for electrode wire production, including a base. A guide groove is formed on the upper surface of the base, a guide block is installed inside the guide groove, a fixing block is fixed above the guide block, a threaded rod passes through the fixing block, a handle is installed above the threaded rod, a pressure plate is movably connected below the handle, and a support frame is fixed to one side of the base.

[0004] The existing electrode wire fixing structure described above uses a bolt-driven pressure plate to fix the electrode wire for subsequent inspection. However, for the inspection of the electrode wire's appearance, this fixing structure is cumbersome to install and remove, affecting the efficiency of the inspection. Furthermore, the pressure of the fixing structure is difficult to control, potentially damaging the electrode wire. Therefore, there is a need for a fixing fixture that facilitates easy installation and removal of the electrode wire and offers high safety for auxiliary electrode wire appearance inspection. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as the cumbersome operation of the electrode wire fixing structure, which affects the inspection efficiency and safety of the electrode wire, and to provide a fixing fixture for assisting the appearance inspection of electrode wires.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A fixture for visual inspection of auxiliary electrode wires includes a fixed base, a support column, and an elastic fixing block. The support column is vertically installed at both ends of the fixed base. The end of the support column away from the fixed base has a mounting groove that mates with the elastic fixing block. The mounting groove has openings on both sides along the long axis of the fixed base. The side of the elastic fixing block away from the support column has a slot that mates with the electrode wire. The slot is located between the openings.

[0008] Preferably, the opening is a U-shaped groove, the openings are symmetrically distributed on the support column and connected to the mounting groove, the width of the opening is less than the width of the elastic fixing block and greater than the width of the slot, the depth of the opening is greater than the depth of the slot and less than the height of the elastic fixing block.

[0009] Preferably, the support column includes a first support column and a second support column, which are symmetrically fixed at both ends of the fixed base. The end face of the first support column with an opening is parallel to the end face of the second support column with an opening.

[0010] Preferably, the elastic fixing block is interference-fitted with the mounting groove.

[0011] Preferably, the slot is a U-shaped groove, and the slot is interference-fitted with the electrode wire.

[0012] Preferably, the elastic fixing block is made of soft silicone.

[0013] Preferably, the upper end of the mounting groove is provided with a sliding baffle, which is a split structure and is symmetrically distributed on both sides of the mounting groove.

[0014] Preferably, the support column is slidably fixed on the fixed base along the long axis of the fixed base.

[0015] Preferably, the fixed base is provided with mounting holes.

[0016] Preferably, the fixed base is provided with a rubber anti-slip pad on the side away from the support column.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) This solution uses a U-shaped structure formed by support columns on a fixed base plate, which, together with the slots on the elastic fixing blocks in the mounting groove, locks the electrode wire in place, facilitating observation of the electrode wire's appearance and improving the accuracy of the inspection. The elasticity of the elastic fixing blocks prevents damage to the electrode wire, and by using the elastic clamping of the electrode wire, no additional mounting and fixing devices are needed, simplifying the electrode wire fixing method, improving the efficiency of the inspection of the electrode wire's appearance, and enabling rapid inspection without damaging the electrode wire, thus improving the safety of the electrode wire fixing.

[0019] (2) In this solution, the elastic fixing block is placed in the mounting groove, which can be flexibly installed and disassembled, thus facilitating the replacement of elastic fixing blocks with different slot sizes, thereby being applicable to the fixing of electrode wires of various sizes and specifications, expanding the scope of application of the fixing fixture.

[0031] Example 1

[0032] like Figure 2 As shown, this embodiment provides a fixture for auxiliary electrode wire appearance inspection, including a fixed base 1, a support column 2, and an elastic fixing block 3. The support column 2 is vertically installed at both ends of the fixed base 1. The end of the support column 2 away from the fixed base 1 is provided with a mounting groove 21 that cooperates with the elastic fixing block 3. The mounting groove 21 has openings 22 on both sides along the long axis of the fixed base 1. The side of the elastic fixing block 3 away from the support column is provided with a slot 31 that cooperates with the electrode wire. The slot 31 is located between the openings 22.

[0033] Working principle: Fix the fixed base 1 on the testing platform, then install the elastic fixing block 3 with the end with the slot 31 facing upwards into the mounting groove 21 on the upper end of the support column 2, completing the installation of the fixing fixture. Next, place the electrode wire into the slot 31 of the elastic fixing block 3 at both ends of the fixed base 1, pass it through the openings 22 on both sides, and suspend it on the support column, thus fixing the electrode wire and enabling subsequent visual inspection of the electrode wire.

[0034] The U-shaped structure formed by the support columns 2 on the fixed base plate 1, combined with the slots 31 on the elastic fixing blocks 3 within the mounting groove 21, locks the electrode wire in place, facilitating observation of its appearance and improving the accuracy of the inspection. The elasticity of the elastic fixing blocks 3 prevents damage to the electrode wire. Furthermore, the elastic clamping of the electrode wire by the elastic fixing blocks 3 eliminates the need for additional mounting and fixing devices, simplifying the electrode wire fixing method, improving the efficiency of appearance inspection, and enabling rapid inspection without damaging the electrode wire, thus enhancing the safety of the electrode wire fixing.

[0035] Preferred implementation methods, such as Figure 1 As shown, the opening 22 is a U-shaped groove. The openings 22 are symmetrically distributed on the support column 2 and are connected to the mounting groove 21. The width of the opening 22 is less than the width of the elastic fixing block 3 and greater than the width of the slot 31. The depth of the opening 22 is greater than the depth of the slot 31 and less than the height of the elastic fixing block 3.

[0036] Furthermore, the support column 2 includes a first support column and a second support column, which are symmetrically fixed at both ends of the fixed base 1. The end face of the first support column with an opening 22 is parallel to the end face of the second support column with an opening 22.

[0037] By setting an installation groove 21 and an opening 22 at the top of the support column, a structure with an installation port at the top and through holes on both sides is formed. This ensures the installation of the elastic fixing block 3 and allows the subsequent electrode wire 4 to be installed in the slot 31, avoiding interference from the side wall of the support column to the electrode wire. The opening end faces of the two support columns are kept as parallel as possible, so that the slots of the elastic fixing blocks 3 on the two support columns can be coaxially distributed. Combined with the elasticity of the elastic fixing blocks 3, this avoids radial force on the electrode wire 4, preventing bending.

[0038] In this embodiment, the elastic fixing block 3 is interference-fitted with the mounting groove 21. The slot 31 is a U-shaped groove, and the slot 31 is interference-fitted with the electrode wire. Specifically, the elastic fixing block 3 is made of soft silicone.

[0039] The interference fit between the elastic fixing block 3 and the mounting groove 21 ensures a secure installation of the elastic fixing block 3. Combined with the interference fit between the slot 31 and the electrode wire 4, this guarantees the stability of the electrode wire 4 while eliminating the need for additional fixing. The use of soft silicone material utilizes its elasticity to prevent additional force on the electrode wire 4, thus avoiding damage or bending during fixing and removal. This improves the ease of installation and removal of the motor wire 4 while ensuring reliability and safety.

[0040] Optionally, a sliding baffle is provided at the upper end of the mounting groove 21. The sliding baffle has a split structure and is symmetrically distributed on both sides of the mounting groove 21. Two sliding baffles can be provided on both sides of the upper end of the mounting groove 21 to vertically limit the two ends of the elastic fixing block 3, further improving the reliability of the elastic fixing block 3 in the mounting groove 21 and avoiding the influence of the electrode wire 4 installation and removal on the position of the elastic fixing block 3.

[0041] In this embodiment, the support column 2 is slidably fixed to the fixed base 1 along the long axis of the fixed base 1. The fixed base 1 is provided with mounting holes 11. A rubber anti-slip pad is provided on the side of the fixed base 1 away from the support column 2.

[0042] The mounting base 1 is fixed to the workbench through the mounting hole 11, which fixes the position of the entire fixture. The anti-slip pad at the bottom assists in the installation, further ensuring the stability of the operation process. The position of the fixture can be flexibly adjusted, and the fixture has strong applicability.

[0043] Specifically, the bottom is a fixed base 1 with mounting holes for fixing on the workbench for easy use. The support columns on both sides are used to place elastic silicone blocks. Soft silicone is used. The slot 31 at the top is used to fix the electrode wire 4. At the same time, the soft silicone can avoid damaging the electrode wire. This allows the appearance of the electrode wire to be observed without damaging it. This fixture is simple to hold the electrode wire and easy to operate. It can quickly observe the appearance of the electrode wire and replace it, improving the efficiency of electrode wire appearance inspection.

[0044] like Figure 1-4 As shown, first, fix this fixture to the workbench through the mounting hole 11 below; place the elastic fixing block 3 made of soft silicone in the mounting groove 21 at the upper end of the support column 2 on both sides; first place the left end of the electrode wire 4 in the slot of the elastic fixing block on the left side, then place the right end of the electrode wire 4 in the elastic fixing block on the right side, and then tighten the electrode wire 4 before performing visual inspection.

[0045] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
