Description
Technical Field
[0001] This utility model relates to the field of compressor parts processing technology, and in particular to a guide structure for electrical discharge machining of compressor parts. Background Technology
[0002] Compressor parts often employ complex, difficult-to-machine structures, such as complex curved surface components, weakly rigid components, low-rigidity process system components, precision mating parts, and complex integral structural components. Among these, weakly rigid and low-rigidity process system components, such as disc-shaft parts, have become one of the important structures widely used in engines. The structural forms of deep holes, blind holes, and stepped holes with large depth-to-diameter ratios are also becoming increasingly common, which increases the difficulty of machining and may even make machining impossible, resulting in a lower and lower finished product qualification rate, or even scrapping. Through electrical discharge machining, compressor parts with complex shapes and high precision requirements can be precisely manufactured, effectively improving the performance and reliability of the parts.
[0003] A search revealed Chinese Patent Publication No. CN204565367U, which discloses an electrode guiding device for an EDM machine in the field of machining equipment. The device includes a base and a double-headed guide. The upper surface of the base has multiple V-blocks spaced apart, each corresponding to a center and used to fix the double-headed guide and the workpiece. The upper surface of the base also has multiple pressure blocks spaced apart; one end of each pressure block is threaded to the base via a locking bolt, and the other end, together with the V-blocks, firmly clamps the double-headed guide or the workpiece. The axis of the double-headed guide coincides with the axis of the deep hole to be machined on the workpiece. This device enables precise electrode positioning for deep hole machining, effectively improving the machining range of the EDM drilling machine. However, for blade components, the above device can only perform vertical positioning; if inclined drilling is required, precise positioning is not possible. Therefore, a guiding structure for EDM machining of compressor components is proposed to solve this problem. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a guide structure for EDM machining of compressor parts, which aims to improve the problem that the electrodes of the EDM machine cannot be tilted for drilling in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a guide structure for EDM machining of compressor parts, comprising a mounting plate, electrodes, and an adjusting plate. A rotating column is rotatably connected to the front side of the mounting plate, and a mounting base is fixedly connected to the front end of the rotating column. A rotating shaft is rotatably connected to the left and right ends of the front side of the mounting plate, and an adjusting plate is fixedly connected to the outer wall of the rotating shaft. A fixing plate is fixedly connected to the left and right ends of the front side of the mounting plate. Adjusting rotating bolts are threadedly connected to the opposite sides of the two fixing plates. Adjacent ends of the two adjusting rotating bolts penetrate the outer wall of the fixing plate and are rotatably connected to connecting pieces. Observation plates are fixedly connected to the outer walls of the two adjusting rotating bolts. Sliding grooves are formed on the opposite sides of the two adjusting plates. The opposite sides of the two connecting pieces are slidably connected to the inner side of the sliding grooves. A fixing mechanism is provided on the front side of the mounting base.
[0006] The above technical solution involves mounting electrodes on a mounting base, which can rotate via a rotating column. According to the actual angle requirements, the adjusting bolts on the two fixed plates are rotated, causing the adjusting bolts to press the adjusting plates to press the two sides of the mounting base at different angles, thereby achieving stable angle adjustment and facilitating precise processing of compressor parts at different angles.
[0007] As a further description of the above technical solution:
[0008] The fixing mechanism includes a clamping plate, which is fixedly connected to the front side of the mounting base. The front side of the mounting base has a triangular groove. The front side of the clamping plate has multiple reinforcing holes. The inner side of each reinforcing hole is threaded with a reinforcing bolt. The rear end of each reinforcing bolt is rotatably connected to a rubber block. The left and right ends of the front side of the clamping plate have connecting holes, and the inner side of each connecting hole is threaded with a connecting bolt.
[0009] The above technical solution involves: initially positioning the electrode using a triangular groove, and fixing the clamping plate to the mounting base using multiple connecting bolts to clamp and fix the electrode. To ensure the stability of the electrode, multiple reinforcing bolts are rotated in conjunction with rubber blocks to achieve stable fixing of the electrode and ensure the accuracy of the wire.
[0010] As a further description of the above technical solution:
[0011] The fixing mechanism also includes two support rods, which are fixedly connected to the bottom of the mounting base.
[0012] The above technical solution allows the support rod to support the bottom of the electrode, facilitating installation and providing support for the electrode.
[0013] As a further description of the above technical solution:
[0014] The two adjusting plates are threadedly connected to each other on opposite sides by a bolt, and the adjacent ends of the two bolts penetrate the outer wall of the adjusting plate and are threadedly connected to a rubber pad.
[0015] The above technical solution involves fixing the rubber pad between the adjusting plates with bolts, thereby improving the service life of the adjusting plates.
[0016] As a further description of the above technical solution:
[0017] The mounting plate has graduations on both the left and right sides of its front side, and multiple screw holes on the front side of the mounting plate.
[0018] The above technical solution allows for precise adjustment of the electrode angle, avoiding errors.
[0019] As a further description of the above technical solution:
[0020] The inner threads of the multiple screw holes are connected to bolts two, the diameter of the bolts two being compatible with the inner diameter of the screw holes.
[0021] The above technical solution involves mounting the plate onto the slide rail with two bolts for reinforcement, enabling subsequent movement and processing.
[0022] As a further description of the above technical solution:
[0023] The front end of the second bolt is provided with a plum blossom groove, and a sealing ring is fixedly connected to the front end of the outer wall of the second bolt.
[0024] Through the above technical solution, the second bolt is easier to fix through the plum blossom groove at the front end. At the same time, the sealing ring can prevent moisture from entering the bolt hole and improve the service life of the second bolt.
[0025] As a further description of the above technical solution:
[0026] An electric wire is installed on the inner side of the electrode, and a water outlet is fixedly connected to the bottom end of the electrode. A water pipe is connected to the rear side of the outer wall of the water outlet.
[0027] The above technical solution involves installing an electric wire inside the electrode, which enables rapid cutting of the mold, and the water outlet component provides heat dissipation for the electric wire.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the adjustment rotating bolt and the connecting part adopt a double rotation mechanism. By using the observation plate and scale as a reference, the adjustment rotating bolt is rotated to push the adjustment plates on both sides to rotate, so as to make precise adjustments, complete the guidance and angle adjustment of the electrode, and realize the processing of accessories with different tricky angles.
[0030] 2. In this utility model, the electrode is supported by a support rod, with the electrode located at the center of the triangular groove. The clamping plate, together with the mounting base, clamps the electrode, and the electrode is initially fixed by connecting bolts. To ensure the stability and accuracy of the electrode, multiple reinforcing bolts are rotated so that the rubber blocks at the ends fit against the outer wall of the electrode, thus completing the complete fixation of the electrode and providing accuracy.

[0039] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of an EDM (Electrical Discharge Machining) guide structure for compressor parts, comprising a mounting plate 1, an electrode 3, and an adjusting plate 8. A rotating column 5 is rotatably connected to the front side of the mounting plate 1. A mounting seat 6 is fixedly connected to the front end of the rotating column 5. The mounting seat 6 is connected to the mounting plate 1 via the rotating column 5, allowing the mounting seat 6 to rotate and thus rotate the electrode 3. A rotating shaft 7 is rotatably connected to the left and right ends of the front side of the mounting plate 1. An adjusting plate 8 is fixedly connected to the outer wall of the rotating shaft 7. The adjusting plate 8 is mounted on both sides of the mounting plate 1 via the rotating shaft 7. The adjusting plate 8 is located on both sides of the mounting seat 6. A fixing plate 9 is fixedly connected to the left and right ends of the front side of the mounting plate 1. Adjusting rotating bolts 10 are threadedly connected to the opposite sides of the two fixing plates 9. The adjusting rotating bolts 10 are supported by the fixing plates 9. The adjacent ends of the two adjusting rotating bolts 10 penetrate the outer wall of the fixing plate 9 and are rotatably connected to a connecting piece 12. An observation plate 11 is fixedly connected to the outer wall of the rotating bolt 10. A sliding groove 13 is provided on the opposite side of the two adjusting plates 8. The opposite sides of the two connecting pieces 12 are slidably connected to the inner side of the sliding groove 13. The adjusting rotating bolt 10 and the adjusting plate 8 are connected by the connecting piece 12. The adjusting plate 8 and the adjusting rotating bolt 10 adopt a double rotation mechanism, which can push the adjusting plate 8 to rotate when the adjusting rotating bolt 10 is rotated. A fixing mechanism 2 is provided on the front side of the mounting base 6. Bolts 14 are threadedly connected to the opposite side of the two adjusting plates 8. The adjacent ends of the two bolts 14 penetrate the outer wall of the adjusting plate 8 and are threadedly connected to rubber pads 15. Scales 16 are provided on the left and right ends of the front side of the mounting plate 1. With the scales 16 on the front side of the mounting plate 1 as a reference, precise adjustment is made through the observation plate 11 to complete the guidance and angle adjustment of the electrode 3, which can realize the processing of accessories with different tricky angles.
[0040] Specifically, the mounting base 6 can be connected to the mounting plate 1 via the rotating column 5 and can rotate freely to adjust the angle of the electrode 3. To further enhance the stability of the structure and the flexibility of adjustment, the left and right ends of the front side of the mounting plate 1 are respectively rotatably connected to the rotating shaft 7. The adjusting plate 8 is mounted on both sides of the mounting plate 1 via the rotating shaft 7 to ensure that its position can be adjusted as needed. The adjusting plate 8 is set on both sides of the mounting base 6 to provide more precise guidance and angle adjustment. In addition, the left and right ends of the front side of the mounting plate 1 are also fixed with fixing plates 9. To achieve more precise adjustment, the adjusting rotating bolt 10 is supported by the fixing plates 9 to ensure its stability and durability. The adjacent ends of the two adjusting rotating bolts 10 are both fixed through. The outer wall of plate 9 is rotatably connected to a connector 12. The connector 12 connects the adjusting rotating bolt 10 and the adjusting plate 8, thus realizing a dual rotation mechanism. This mechanism can push the adjusting plate 8 to rotate when the adjusting rotating bolt 10 is rotated, thereby guiding and adjusting the angle of the electrode 3. In order to facilitate precise adjustment by the operator, scales 16 are provided on both the left and right ends of the front side of the mounting plate 1. These scales 16, together with the scales 16 on the front side of the mounting plate 1, are used as a reference. Precise adjustment is made by observing the plate 11, thereby completing the guidance and angle adjustment of the electrode 3. This design allows the guiding structure to adapt to the processing of accessories with different tricky angles, greatly improving the flexibility and efficiency of processing.

Connecting holes 206 are provided on both the left and right ends of the front side of the clamping plate 201, with connecting bolts 207 threadedly connected to the inner side of each connecting hole 206. Plate 201, in conjunction with mounting base 6, clamps electrode 3 and connects it to connecting hole 206 via connecting bolt 207 to achieve initial fixation of electrode 3. To ensure the stability and accuracy of electrode 3, multiple reinforcing bolts 204 on the front side are rotated to make the rubber block 205 at the end fit against the outer wall of electrode 3, thus completing the complete fixation of electrode 3 and providing accuracy. Fixing mechanism 2 also includes two support rods 208, which are fixedly connected to the bottom of mounting base 6. The support rods 208 and mounting base 6 are integrally formed. The support rods 208 can support electrode 3, facilitating subsequent installation support.
[0042] Specifically, a triangular groove 202 is provided on the front side of the mounting base 6. The purpose of this triangular groove 202 is to accurately position the electrode 3 at the center of the mounting base 6. To further enhance the stability of the structure, the electrode 3 can be effectively clamped by the tight fit between the clamping plate 201 and the mounting base 6. At the same time, the electrode 3 is initially fixed by the connection between the connecting bolt 207 and the connecting hole 206. To ensure the stability and accuracy of the electrode 3, the operator can rotate the multiple reinforcing bolts 204 on the front side to make the rubber block 205 at the end fit tightly against the outer wall of the electrode 3, thereby completing the complete fixation of the electrode 3 and ensuring the accuracy of the operation. The support rod 208 is integrally formed with the mounting base 6. This design allows the support rod 208 to provide additional support for the electrode 3, thereby facilitating subsequent installation and support work.
[0043] Reference Figure 1 , Figure 4 and Figure 5 The front side of the mounting plate 1 is provided with multiple screw holes 17. The inner side of the screw holes 17 is threaded with bolts 18. The diameter of bolts 18 is matched with the inner diameter of screw holes 17. The front end of bolts 18 is provided with a plum blossom groove 19.

A water outlet 21 is fixedly connected to the bottom end of the electrode 3. A water pipe 22 is connected to the rear side of the outer wall of the water outlet 21.
[0044] Specifically, multiple screw holes 17 are distributed on the front side of the mounting plate 1. The diameter of the bolt 2 18 is perfectly matched with the inner diameter of the screw hole 17 to ensure tightness of connection. In addition, the front end of the bolt 2 18 is specially designed with a plum blossom groove 19, which not only increases the friction when tightening, but also facilitates tool gripping. To further ensure the sealing of the connection, a sealing ring 20 is fixedly connected to the front end of the outer wall of the bolt 2 18, which effectively prevents leakage of liquid or gas. The wire 4 is installed on the inner side of the electrode 3, which provides the necessary electrical connection for the normal operation of the equipment. The bottom end of the electrode 3 is fixed with a water outlet 21. The water outlet 21 is not only responsible for dissipating the heat generated during the operation, but also ensures the cooling effect of the equipment. The rear side of the outer wall of the water outlet 21 is connected to a water pipe 22, which allows the cooling water to circulate smoothly, thereby maintaining the equipment at the optimal operating temperature.
[0045] Working principle: First, the mounting base 6 is connected to the mounting plate 1 via the rotating column 5. The adjusting plate 8 is mounted on both sides of the mounting plate 1 via the rotating shaft 7. The adjusting rotating bolt 10 is supported by the fixing plate 9. The adjusting plate 8 and the adjusting rotating bolt 10 are connected by the connector 12. A double rotation mechanism is adopted. By using the observation plate 11 and the scale 16 on the front side of the mounting plate 1 as a reference, the adjusting rotating bolt 10 is rotated to push the adjusting plate 8 to rotate, so as to make precise adjustments and complete the guidance and angle adjustment of the electrode 3.
[0046] Furthermore, the electrode 3 is supported by the support rod 208, and the electrode 3 is precisely positioned in the center of the mounting base 6 by the triangular groove 202. The clamping plate 201 clamps the electrode 3 in conjunction with the mounting base 6, and the electrode 3 is initially fixed by connecting the connecting bolt 207 to the connecting hole 206. In order to ensure the stability and accuracy of the electrode 3, the multiple reinforcing bolts 204 on the front side are rotated to make the rubber block 205 at the end fit against the outer wall of the electrode 3, thus completing the complete fixation of the electrode 3.
