Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold tooling technology, specifically relating to a novel copper electrode tooling fixture. Background Technology
[0002] Molds are tools used to create shaped items. Typically, molds for producing plastic or rubber products are machined using CNC milling machines. However, due to the limitations of the cutting tools, CNC milling machines cannot accurately machine right angles, arcs, grooves, and other structural features, preventing the molds from meeting production requirements. Therefore, further machining using copper electrodes on an electrical discharge machining (EDM) machine is necessary to achieve the desired production specifications. The copper electrode, as an intermediate step in mold manufacturing, is usually purchased as a single piece of material. It is first machined into the required shape on a CNC milling machine, and then transferred along with the fixture to the next EDM machining step.
[0003] In existing technologies, precision EROWA fixtures are commonly used as clamps for copper electrodes. EROWA fixture systems are widely used in precision manufacturing (especially mold making and precision parts machining), and have the ability to provide high-precision positioning and quick changeover. They can minimize the preparation time of machine tools (such as machining centers, EDM machines, milling and turning centers, inspection equipment, etc.) and improve equipment utilization and machining accuracy consistency.
[0004] However, when manufacturing copper electrodes on a CNC milling machine, the existing EROWA fixtures are very wasteful of materials, which greatly increases production costs. Therefore, there is an urgent need for a new type of copper electrode tooling fixture that can improve clamping efficiency, save materials, and reduce production costs. Utility Model Content
[0005] In view of the problems existing in the prior art, this utility model provides a new type of copper electrode tooling fixture, which can improve clamping efficiency, save materials, and greatly reduce production costs.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A novel copper electrode fixture is mounted on a CNC milling machine worktable. It includes a locking screw, an electrode fixing seat, an EROWA fixture, a pull rod, an EROWA fixture base, and a fixture base. The fixture base is fixed to the CNC milling machine worktable, and the EROWA fixture base is fixed to the fixture base. The EROWA fixture is movably mounted on the EROWA fixture base via the pull rod. The electrode fixing seat is T-shaped, and the EROWA fixture has a groove that matches the T-shape. The copper electrode is detachably mounted on the top of the electrode fixing seat via the locking screw, and the electrode fixing seat is detachably mounted within the groove of the EROWA fixture.
[0007] Furthermore, the bottom of the copper electrode is provided with a locking screw hole that is compatible with the locking screw.
[0008] Furthermore, the EROWA fixture has multiple locking screws on the side wall of the groove, and the electrode holder has locking holes that are compatible with the locking screws.
[0009] Furthermore, a fixture base fixing plate is provided on the fixture base, and the fixture base fixing plate is provided with fixing bolts and positioning height screws. The fixture base is fixed to the CNC milling machine worktable by fixing bolts, and the height of the fixture base on the CNC milling machine worktable is adjusted by positioning height screws.
[0010] Furthermore, the ROWA fixture base is equipped with a pneumatic tensioning device inside, and the ROWA fixture base is also equipped with an air inlet and outlet pipe, which is connected to an air compressor to supply and discharge working gas to the pneumatic tensioning device.

By adding a T-shaped electrode fixing seat, it not only achieves quick clamping and disassembly of the copper electrode, improving clamping efficiency, but also saves large amounts of copper material.

[0018] like Figures 1-2 As shown, a novel copper electrode fixture is mounted on a CNC milling machine worktable 8.
