Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrode assembly structures, in particular to an electrode assembly that prevents bending deformation. Background Art
[0002] The structure of a certain metal part is as Figure 1 shown. The metal part 1 has a long strip structure. After a batch of metal parts 1 are produced in the workshop, the process requires machining a groove 2 on the end face at one end of the metal part 1. As Figure 2 shown is the structural schematic diagram of the product with the groove 2 machined.
[0003] Currently, a certain workshop uses an electric discharge machining device in cooperation with an electrode assembly to machine the groove 2 on the metal part 1. Among them, the structure of the electrode assembly is as Figure 3 shown. It includes a conductive strip seat A3. A plurality of conductive column heads A4 are fixedly arranged at intervals on the bottom surface of the conductive strip seat A3. A discharge plate 5 is fixedly arranged on the bottom surface of each conductive column head A4. The rear end face of the discharge plate 5 is flush with the rear end face of the conductive column head A4.
[0004] Before use, the worker fixes the conductive strip seat A3 of the electrode assembly on the chuck of the electric discharge machining device, and then fixes three metal parts 1 on the fixture through the fixture. During use, the chuck of the electric discharge machining device is controlled to move downward. The chuck drives the conductive strip seat A3 to move downward. The conductive strip seat A3 drives three conductive column heads A4 to move downward synchronously. The conductive column heads A4 drive the discharge plates 5 connected thereto to move downward synchronously. The three discharge plates 5 move respectively towards the top ends of the three metal parts 1. During the downward movement, the discharge plates 5 perform electro-corrosion on the metal parts 1. When the discharge plates 5 move downward to the set stroke, a groove 2 can be finally machined on each of the three metal parts 1 respectively, as Figure 4 shown, and then three products can be produced at one time.
[0005] However, although this electrode assembly can be used, after long-term use for a period of time, the following technical defects are still shown:
[0006] I. Since the thickness of the discharge plate 5 is only 1 - 1.2 cm and the thickness is relatively thin, when the discharge plate 5 performs electro-corrosion on the metal part 1, the discharge plate 5 is very easy to bend and deform forward, and thus the outer contour of the machined groove 2 does not meet the design requirements, thereby reducing the production quality of the product.
[0007] II. Since the conductive strip seat A3, the conductive column heads A4 and the discharge plate 5 are integrally formed, when the discharge plate 5 is damaged, only the whole electrode assembly can be scrapped and then a new electrode assembly is replaced, which undoubtedly increases the production cost of the product.
[0008] Therefore, there is an urgent need for an electrode assembly that can effectively avoid the bending deformation of the discharge plate and reduce production costs. Summary of the Invention
[0009] The purpose of the present utility model is to overcome the shortcomings of the prior art and provide an anti-bending deformation electrode assembly with a compact structure, which can effectively avoid the bending deformation of the discharge plate and reduce production costs.
[0010] The purpose of the present utility model is achieved through the following technical solutions: An anti-bending deformation electrode assembly includes a conductive strip-shaped seat B. A plurality of blind slots are arranged at intervals along the length direction on the bottom surface of the conductive strip-shaped seat B. Through holes are provided on the top surface of the conductive strip-shaped seat B, and each through hole is connected to a corresponding blind slot. A conductive stud B is embedded in each blind slot. A threaded hole communicating with the through hole is provided on the top surface of the conductive stud B. The conductive stud B is fixed on the conductive strip-shaped seat B by a screw passing through the through hole and being threadedly connected to the threaded hole.
[0011] A discharge plate is fixedly provided on the bottom surface of each conductive stud B. The rear end face of the discharge plate is flush with the rear end face of the conductive strip-shaped seat B. A strip-shaped member is fixedly provided between the front end face of the discharge plate and the bottom surface of the conductive stud B.
[0012] Three blind slots are provided on the bottom surface of the conductive strip-shaped seat B, and the distance between every two adjacent blind slots is equal.
[0013] The outer contour of the conductive stud B matches the outer contour of the blind slot.
[0014] The front end face of the strip-shaped member is flush with the front end face of the conductive stud B.
[0015] The strip-shaped member is fixedly provided at the middle of the discharge plate, and the length of the strip-shaped member is less than the length of the discharge plate.
[0016] The present utility model has the following advantages: a compact structure, effectively avoiding the bending deformation of the discharge plate, and reducing production costs. Description of the Drawings

[0030] The following further describes the present utility model in conjunction with the accompanying drawings. The protection scope of the present utility model is not limited to the following:
[0031] As Figures 5 to 9 shown, an electrode assembly for preventing bending deformation includes a conductive strip seat B6. A plurality of blind grooves 7 are arranged at intervals along the length direction on the bottom surface of the conductive strip seat B6. A plurality of through holes 8 respectively communicating with the blind grooves 7 are provided on the top surface of the conductive strip seat B6. A conductive column head B9 is embedded in each blind groove 7. The outer contour of the conductive column head B9 matches the outer contour of the blind groove 7. A threaded hole 10 communicating with the through hole 8 is provided on the top surface of the conductive column head B9. The conductive column head B9 is fixed on the conductive strip seat B6 through a screw 11 passing through the through hole 8 and being threadedly connected with the threaded hole 10. Three blind grooves 7 are provided on the bottom surface of the conductive strip seat B6, and the distance between every two adjacent blind grooves 7 is equal.
[0032] A discharge plate 5 is fixedly provided on the bottom surface of each conductive column head B9. The rear end face of the discharge plate 5 is flush with the rear end face of the conductive strip seat B6. A strip part 12 is fixedly provided between the front end face of the discharge plate 5 and the bottom surface of the conductive column head B9. The front end face of the strip part 12 is flush with the front end face of the conductive column head B9. The strip part 12 is fixedly provided at the middle of the discharge plate 5, and the length of the strip part 12 is less than the length of the discharge plate 5.
[0033] The working process of the utility model is as follows:
[0034] S1. The worker fixes the conductive strip seat B6 of the electrode assembly on the chuck of the electric discharge machining equipment, and then clamps the bottom ends of the three metal parts 1 through a fixture;
[0035] S2. The worker controls the chuck of the electric discharge machining equipment to move downward. The chuck drives the conductive strip seat B6 to move downward. The conductive strip seat B6 drives the three conductive column heads B9 to move downward synchronously. The conductive column heads B9 drive the discharge plates 5 connected thereto to move downward synchronously. The three discharge plates 5 move respectively towards the top ends of the three metal parts 1. During the downward movement, the discharge plates 5 perform electro-corrosion on the metal parts 1. When the discharge plates 5 move downward to the set stroke, a groove 2 can be finally machined on each of the three metal parts 1 respectively, as Figure 10 shown, and thus three products can be produced at one time.
[0036] Among them, it can be known from this step S2 that since a strip member 12 is fixedly arranged between the front end surface of the discharge plate 5 and the bottom surface of the conductive column head B9, and the strip member 12 is fixedly arranged at the center of the discharge plate 5, therefore, when the discharge plate 5 performs electro-corrosion on the metal part 1, the strip member 12 blocks the forward deformation of the discharge plate 5, thereby ensuring that the outer contour of the machined groove 2 meets the design requirements. It can be seen from this that compared with the electrode assembly used in the workshop, the production quality of the products of this electrode assembly is greatly improved.
[0037] S3. The removal of the three products, and the specific operation steps are as follows:
[0038] S31. The worker controls the chuck of the electric discharge machining equipment to move upward. The chuck drives the conductive strip seat B6 to move upward. The conductive strip seat B6 drives the three conductive column heads B9 to move upward synchronously. The conductive column heads B9 drive the discharge plates 5 connected thereto to move upward synchronously. The discharge plates 5 withdraw from the products;
[0039] S32. The worker opens the fixture, and the fixture no longer clamps the three products. Then the worker takes away the three machined products;
[0040] S4. The worker repeats the operations of steps S2~S3 in this way, and multiple products can be continuously machined.
[0041] In addition, when a discharge plate 5 is damaged, a worker only needs to unscrew the screw 11 corresponding to the discharge plate 5, and then pull out the conductive terminal B9 connected to the discharge plate 5 from the blind groove 7. After pulling out, a new conductive terminal B is re-embedded into the blind groove 7, and finally the new conductive terminal B is fixed with a screw, thus realizing the replacement of the discharge plate 5. After replacement, the electrode assembly can be used continuously. It can be seen that compared with the electrode assemblies used in the workshop, the whole electrode assembly of the present invention does not need to be scrapped, thus greatly saving the production cost.
[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
