Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for wire EDM processing, specifically a fast balancing fixture for wire EDM. Background Technology

[0002] Wire EDM was developed based on electrical discharge machining (EDM) for drilling and forming. It uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as an electrode wire. The pulsed electric spark discharge between the electrode wire and the workpiece generates high temperature, which melts or vaporizes the metal, forming a kerf, thereby cutting out the part.

[0003] Before wire EDM machining of a part, a fixture is needed to fix the part on the worktable. Existing wire EDM tools generally suffer from the problem of easy datum misalignment, especially when multiple fixtures are used to fix a part at the same time, it is difficult to maintain the balance of multiple datum planes; and existing fixtures are not suitable for parts of different heights or thicknesses, requiring the removal of bolts and replacement of clamping plates, resulting in a lot of wasted time and reduced machining efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fast balancing fixture for wire cutting.

[0005] A quick balancing fixture for wire cutting includes a fixed base, a mounting base fixedly disposed on the lower rear side of the fixed base, a reference clamping plate fixedly disposed on the lower front side of the fixed base, a movable base slidably disposed on the front side of the fixed base via a sliding connection device, a movable clamping plate cooperating with the reference clamping plate fixedly disposed on the upper front side of the movable base, and a moving device for driving the movable base to rise and fall is rotatably disposed inside the fixed base.

[0006] Furthermore, the moving device includes a threaded screw and a lifting helical rack. The fixed base has a drive cavity inside, and the threaded screw is rotatably installed in the drive cavity. A drive rod is fixedly connected to the center of the upper part of the threaded screw by a connecting key. The top of the fixed base has a connecting hole that communicates with the drive cavity. The drive rod passes through the connecting hole and is movably connected to it. An adjusting head is fixedly installed on the top of the drive rod. A lifting helical rack that cooperates with the threaded screw is fixedly installed at the rear of the moving base.

[0007] Furthermore, the sliding connection device includes a sliding groove and a slider that slide together. The front of the fixed seat is provided with a sliding groove, and sliders are fixedly provided on both sides of the movable seat. The movable seat and the lifting helical rack are arranged in the sliding groove and are slidably connected to the fixed seat through the sliding groove and the sliders.

[0008] Furthermore, a drive port for connecting the drive cavity and the slide groove is provided on the fixed seat on the front side of the drive cavity, and the outer wall of the threaded screw extends to the outside of the drive port and rotates with it.

[0009] Furthermore, the mounting base has an open long slot in the middle.

[0010] In summary, this utility model has the following beneficial effects: This invention relates to a quick-balancing fixture for wire EDM. Multiple fixtures are fixedly mounted on a worktable via mounting bases. The top surfaces of the reference clamping plates of these fixtures are aligned on a single reference plane, ensuring balance. By rotating a moving device, the moving clamping plate descends with the assistance of a sliding connection device. The reference clamping plate and the moving clamping plate work together to clamp the workpiece. This design is simple to operate, provides stable clamping, and ensures the quality of wire EDM processing. Furthermore, this invention eliminates the need to remove bolts or replace clamping plates, making it suitable for parts of varying heights and thicknesses, saving operation time and improving processing efficiency.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-5 As shown, a quick balancing fixture for wire cutting includes a fixed base 1, a mounting base 2 fixedly disposed on the lower rear side of the fixed base 1, a reference clamping plate 4 fixedly disposed on the lower front side of the fixed base 1, a movable base 5 slidably disposed on the front side of the fixed base 1 via a sliding connection device, a movable clamping plate 6 cooperating with the reference clamping plate 4 fixedly disposed on the upper front side of the movable base 5, a moving device for driving the movable base 5 to rise and fall is rotatably disposed inside the fixed base 1, and an open long slot 3 is provided in the middle of the mounting base 2.

[0015] In this embodiment, before use, multiple wire EDM quick-balancing fixtures are fixedly mounted on the worktable using mounting base 2 according to requirements. Preferably, bolts and nuts penetrating the elongated slot 3 are used to fasten the mounting base 2 to the worktable. At this time, the top surfaces of the reference clamping plates 4 of the multiple wire EDM quick-balancing fixtures are on a reference plane. The bottom surface of the part is placed on the top surface of the reference clamping plates 4 of the multiple wire EDM quick-balancing fixtures, and then the moving device is rotated in sequence, causing the moving clamping plate 6 to descend with the cooperation of the sliding connection device. The reference clamping plate 4 and the moving clamping plate 6 cooperate to clamp the part.

[0016] The moving device includes a threaded screw 10 and a lifting helical rack 14. The fixed base 1 has a drive cavity 9 inside, and the threaded screw 10 is rotatably installed in the drive cavity 9. A drive rod 11 is fixedly connected to the center of the upper part of the threaded screw 10 through a connecting key 12. The top of the fixed base 1 has a connecting hole 15 that communicates with the drive cavity 9. The drive rod 11 passes through the connecting hole 15 and is movably connected to it. An adjusting head 16 is fixedly installed on the top of the drive rod 11. The rear of the moving base 5 is fixedly installed with a lifting helical rack 14 that cooperates with the threaded screw 10.

[0017] The sliding connection device includes a sliding groove 7 and a slider 8 that slide together. The front part of the fixed seat 1 is provided with a sliding groove 7, and the two sides of the movable seat 5 are fixedly provided with sliders 8. The movable seat 5 and the lifting helical rack 14 are arranged in the sliding groove 7 and are slidably connected to the fixed seat 1 through the sliding groove 7 and the sliders 8.

[0018] A drive port 13 for connecting the drive cavity 9 and the slide groove 7 is provided on the fixed seat 1 on the front side of the drive cavity 9. The outer wall of the threaded screw 10 extends to the outside of the drive port 13 and rotates with it.

[0019] In this embodiment, a tool is used to rotate the adjusting head 16. The adjusting head 16 drives the threaded screw 10 to rotate via the drive rod 11 and the connecting key 12. The threaded screw 10, through its threaded engagement with the lifting helical rack 14, drives the moving seat 5 and the moving clamping plate 6 to move downwards along the sliding groove 7 and the slider 8. The downwardly moving clamping plate 6 engages with the reference clamping plate 4 to clamp the part. Preferably, the teeth of the threaded screw 10 and the lifting helical rack 14 are both trapezoidal structures with a wider inner surface and a narrower outer surface, resulting in a tight threaded rotation and stable clamping.
