Description

Technical Field

[0001] This utility model relates to the field of roller surface electrical discharge texturing technology, specifically to a roughness control device for copper alloy roller surface electrical discharge texturing. Background Technology

[0002] In order to form a uniform rough texture on the surface of the copper alloy roller and thus optimize the surface properties of the roller, an electrical discharge texturing bed is usually used. The electrical discharge texturing process forms uniform pits on the surface of the copper alloy roller, ultimately achieving the target roughness. In existing technology, the roller to be processed is fixed on an electrical discharge texturing bed, with a copper alloy roller as the workpiece electrode and copper or graphite as the tool electrode. An insulating working fluid is sprayed onto the workpiece, and an electrical pulse of a certain amplitude and frequency is applied between the two electrodes. Under certain conditions, a pulsed spark discharge will be generated between the two electrodes. Each discharge forms a tiny discharge pit on the workpiece surface, thus forming a texturing surface composed of a series of pits, thereby completing the texturing process. However, traditional electrical discharge texturing devices do not have an adjustment structure for the gap between the two electrodes. When encountering different workpieces and processing requirements, it is necessary to adjust the gap between the two electrodes in a timely manner to achieve the processing of the workpiece. Moreover, the roughness of the roller surface texturing mainly depends on the electrode gap. Due to the lack of an adjustment structure for the gap between the two electrodes, it is also difficult to control the roughness of the roller surface texturing. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a copper alloy roller surface EDM roughening control device, which solves the technical problem that the prior art does not have an adjustment structure for the two-stage gap, requires timely adjustment of the two-stage gap to achieve the processing of workpieces of different sizes, and also makes it difficult to control the roughness of the roller surface roughening.

[0004] According to one aspect, at least one embodiment of the present invention provides a copper alloy roller surface electrical discharge machining roughness control device, including a base, on which a fixed rotation mechanism is provided for supporting and fixing the copper alloy roller and driving the copper alloy roller to rotate, and further including a mounting seat, a moving mechanism, a mounting plate, a driving mechanism and a displacement measuring component. The mounting seat is slidably disposed on the base and has a slot. The moving mechanism is disposed on the base and is used to drive the mounting seat to move along the axial direction of the copper alloy roller. The mounting plate is slidably disposed in the slot and has a plurality of electrodes evenly mounted on the mounting plate. The driving mechanism is disposed in the mounting seat and is used to drive the mounting plate to move along the inner wall of the slot. The displacement measuring component is disposed on the driving mechanism and is used to cooperate with the driving mechanism to measure the moving distance of the mounting plate.

[0006] Furthermore, the drive mechanism includes an electric cylinder and a guide assembly. The electric cylinder is mounted on the mounting base, and its output end passes through the mounting base and is fixedly connected to one end of the mounting plate. The guide assembly is disposed on the mounting plate and is used to guide the movement of the mounting plate.

[0007] Furthermore, the guiding assembly includes a guide plate and a guide rod. The guide plate is fixedly connected to both ends of the mounting plate.

The fixed rotation mechanism 2 is the key structure of the copper alloy roller surface EDM roughening device. It is mainly fixed by the copper alloy roller 3 to be processed by the clamping parts and driven by the motor to rotate the copper alloy roller 3. It also includes a mounting base 4, a moving mechanism, a mounting plate 6, a driving mechanism and a displacement measuring component. like Figure 2 As shown, the mounting base 4 is slidably mounted on the base 1. The mounting base 4 has a slot 5, which is inclined and the opening is perpendicular to the axis of the copper alloy roller 3. The moving mechanism is mounted on the base 1 and is used to drive the mounting base 4 to move along the axis of the copper alloy roller 3. The moving mechanism includes a threaded rod 8, a drive motor 10, and a moving plate 11. The base 1 has a moving groove 9. The threaded rod 8 is rotatably mounted in the moving groove 9 and is parallel to the copper alloy roller 3. A telescopic protective sleeve is fitted on the outside of the threaded rod 8. The drive motor 10 is mounted on the base 1. The output end of the drive motor 10 is coaxially and fixedly connected to one end of the threaded rod 8. The moving plate 11 is slidably mounted in the moving groove 9 and threadedly connected to the threaded rod 8. The moving plate 11 is fixedly connected to the bottom end of the mounting base 4. By starting the drive motor 10, the output end of the drive motor 10 drives the threaded rod 8 to rotate. The threaded rod 8 drives the moving plate 11 to move along the inner wall of the moving groove 9. The moving plate 11 drives the mounting base 4 to move parallel to the electrode 7 and the copper alloy roller 3. like Figure 2 As shown, the mounting plate 6 is slidably disposed within the empty groove 5. Multiple electrodes 7 are evenly mounted on the mounting plate 6, arranged uniformly to react with the copper alloy roller 3 (workpiece electrode 7), creating pits on the copper alloy roller 3. A drive mechanism is disposed within the mounting base 4, used to move the mounting plate 6 along the inner wall of the empty groove 5. The drive mechanism includes an electric cylinder 12 and a guide assembly. The electric cylinder 12 is mounted on the mounting base 4, and its output end passes through the mounting base 4 and is fixedly connected to one end of the mounting plate 6. The guide assembly is disposed on the mounting plate 6 to guide its movement. The guide assembly includes... Guide plate 13 and guide rod 15, both ends of mounting plate 6 are fixedly connected to guide plate 13, mounting base 4 is provided with sliding groove 14 that cooperates with guide plate 13, guide rod 15 is fixedly set in sliding groove 14, guide rod 15 passes through guide plate 13 and is slidably connected to guide plate 13, guide rod 15 is parallel to the output end of electric cylinder 12, by starting electric cylinder 12, the output end of electric cylinder 12 pushes mounting plate 6 to move along the inner wall of empty groove 5, mounting plate 6 moves under the guidance of guide plate 13 and guide rod 15, mounting plate 6 drives multiple electrodes 7 to move closer to or away from the surface of copper alloy roller 3; like Figure 2 and Figure 3As shown, the displacement measuring component is mounted on the drive mechanism to measure the movement distance of the mounting plate 6. The displacement measuring component includes a connecting plate 16, an indicator arrow 18, and a scale 19. One end of the connecting plate 16 is fixedly connected to a guide plate 13. A slot 17 is provided on the mounting base 4, and the connecting plate 16 slides against the inner wall of the slot 17. The slot 17 is inclined and parallel to the empty slot 5. The indicator arrow 18 is located outside the mounting base 4 and perpendicularly faces the scale 19. Figure 4 As shown, the slide 14, empty groove 5, and slot 17 are all connected. The marking arrow 18 is fixedly connected to the other end of the connecting plate 16. The scale 19 is fixedly set on the mounting base 4 and located below the marking arrow 18. The mounting plate 6 and two guide plates 13 are moved by the electric cylinder 12. One guide plate 13 drives the connecting plate 16 to move along the inner wall of the slot 17. The connecting plate 16 drives the marking arrow 18 to move at an angle. When the distance between the electrode 7 and the surface of the copper alloy roller 3 is appropriate (to control the roughness of the pit), the position of the marking arrow 18 toward the scale 19 is determined, and the scale on the scale 19 can be known. It should be added that the electrode 7 is tilted vertically toward the axis of the copper alloy roller 3. By measuring the straight distance between the axis of the fixed copper alloy roller 3 and the electrode 7 in advance when the marking arrow 18 is at the "0" scale, the distance between the surface of the copper alloy roller 3 and the electrode 7 is calculated by the scale where the marking arrow 18 is located after the electrode 7 moves, so as to control the roughness. Working principle: When performing EDM roughening on the copper alloy roller 3, this copper alloy roller surface roughening control device fixes the copper alloy roller 3 to be processed on the fixed rotating mechanism 2, starts the electric cylinder 12, and the output end of the electric cylinder 12 pushes the mounting plate 6 to move along the inner wall of the slot 5. Under the guidance of the guide plate 13 and the guide rod 15, the mounting plate 6 drives multiple electrodes 7 to move closer to or away from the surface of the copper alloy roller 3. One guide plate 13 drives the connecting plate 16 to move along the inner wall of the slot 17. The connecting plate 16 drives the marking arrow 18 to move tilted. When the distance between the electrode 7 and the surface of the copper alloy roller 3 is appropriate (controlling the roughness of the pit formation), the position of the marking arrow 18 pointing towards the scale 19 is determined. The scale on the ruler 19 can be known, and the distance between the surface of the copper alloy roller 3 and the electrode 7 can be calculated. With the electric spark discharge parameters kept constant, the surface roughness of the copper alloy roller 3 can be controlled in this way. By driving the copper alloy roller 3 to rotate, a pulsed spark discharge will be generated between the two poles (copper alloy roller 3 and electrode 7). Each discharge forms a tiny discharge pit on the surface of the workpiece. Therefore, a roughened surface composed of a series of pits can be formed on the surface. By starting the drive motor 10, the output end of the drive motor 10 drives the threaded rod 8 to rotate. The threaded rod 8 drives the moving plate 11 to move along the inner wall of the moving groove 9. The moving plate 11 drives the mounting base 4 to move parallel to the electrode 7 and the copper alloy roller 3. The surface of the copper alloy roller 3 can be roughened with full coverage.
