Abstract

A movable seat is movably fitted to the upper end of the trapezoidal conductive block. A bolt is threaded onto the upper part of the connector, and a U-shaped spring is fixedly connected to the rear of the trapezoidal conductive block. The lower part of the U-shaped spring is fixedly connected to the lower part of the connector, and the lower end of the bolt is in movable contact with the movable seat. The connector includes a base, the upper end of which has a threaded hole into which the bolt is threaded. Tightening the bolt causes it to act downwards on the movable seat, which in turn acts downwards on the trapezoidal conductive block, clamping the electrode downwards. When the electrode is subjected to an outward pulling force, it acts backwards on the trapezoidal conductive block. The movable seat guides the trapezoidal conductive block downwards, further clamping the electrode and improving the stability of the clamped electrode.

Description

Technical Field

[0001] This utility model belongs to the technical field of high-frequency response electrode clamping tools for pulse electrolytic machining, and particularly relates to a high-frequency response electrode clamping device for pulse electrolytic machining. Background Technology

[0002] The high-frequency response electrode of pulse electrolytic machining needs to be clamped and fixed by an electrode fixture. The electrode fixture is a special tooling used in precision manufacturing fields such as electrical discharge machining and electrolytic machining (including pulse electrolytic machining) to accurately fix and position the electrode and realize the reliable connection between the electrode and the machining equipment. Its core function is to ensure the stability of the electrode position during the machining process.

[0003] Since conventional electrode clamps are mainly fixed by screws, the clamping points are prone to loosening due to thermal expansion and contraction caused by temperature differences. Furthermore, they cannot tighten themselves after being subjected to loosening tension, which causes the conventional electrode clamps used to hold high-frequency response electrodes for pulse electrolytic machining to loosen easily.

[0004] To address these issues, we propose a high-frequency response electrode clamping device for pulse electrolytic machining. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional electrode clamps used to hold high-frequency response electrodes in pulse electrolytic machining are prone to loosening, and to propose a high-frequency response electrode clamping device for pulse electrolytic machining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-frequency response electrode clamping device for pulse electrolytic machining includes a connector, inside which a trapezoidal conductive block is movably mounted. A movable seat is movably fitted to the upper end of the trapezoidal conductive block. A bolt is threaded onto the upper part of the connector. A U-shaped spring is fixedly connected to the rear of the trapezoidal conductive block, and the lower part of the U-shaped spring is fixedly connected to the lower part of the connector. The lower end of the bolt is in movable contact with the movable seat. An electrode is inserted under the trapezoidal conductive block, and the bolt is tightened, causing the bolt to act downwards on the movable seat, which in turn acts downwards on the trapezoidal conductive block, clamping the electrode downwards. When the electrode is subjected to an outward pulling force, the electrode acts backwards on the trapezoidal conductive block. The movable seat guides the trapezoidal conductive block downwards, further clamping the electrode and improving the stability of the clamped electrode.

[0007] Preferably, the connector includes a base, the upper end of which has a threaded hole, and a bolt is threaded into the threaded hole. The threaded hole facilitates guiding the bolt to move up and down spirally.

[0008] Preferably, the base has a fixing slot inside, and the lower part of the U-shaped spring is fixedly engaged in the fixing slot. The fixing slot facilitates the fixed assembly of the U-shaped spring and the base.

[0009] Preferably, the movable seat includes a trapezoidal block, which is movably engaged inside the seat. The lower end of the bolt is in movable contact with the upper end of the trapezoidal block. A first baffle is fixedly connected to one end of the trapezoidal block, and the first baffle is in movable contact with the seat. Tightening the bolt causes it to act downwards on the trapezoidal block, which in turn acts downwards on the trapezoidal conductive block, facilitating control of the trapezoidal conductive block pressing against the target electrode.

[0010] Preferably, the movable base further includes a second baffle, which is in movable contact with the base and whose lower end is fixedly connected to the trapezoidal block. The second baffle is used to block the trapezoidal block from falling out of the base.

[0011] Preferably, the trapezoidal conductive block includes a pressure plate, and the upper end of the pressure plate has a guide surface. When the lower part of the pressure plate is subjected to an outward pulling force, the pressure plate slides slightly outward, causing the guide surface to slide downward along the trapezoidal block. The trapezoidal block acts on the guide surface, causing the pressure plate to act further downward on the target electrode, facilitating self-tightening.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Insert the electrode into the lower side of the trapezoidal conductive block, and then tighten the bolt. The bolt will act downward on the movable seat, which in turn will act downward on the trapezoidal conductive block. This will cause the trapezoidal conductive block to clamp the electrode downward. When the electrode is subjected to an outward pulling force, it will act backward on the trapezoidal conductive block. The movable seat will guide the trapezoidal conductive block downward, further clamping the electrode and improving the stability of the electrode clamping.

[0013] 2. Tighten the bolts so that they act downwards on the trapezoidal block, which in turn acts downwards on the trapezoidal conductive block, making it easier to control the trapezoidal conductive block to press against the target electrode.

[0014] 3. When the lower part of the pressure plate is subjected to an outward pulling force, the pressure plate slides slightly outward, causing the guide surface to slide down along the trapezoidal block. The trapezoidal block acts on the guide surface, causing the pressure plate to act further downward on the target electrode, facilitating self-tightening. Attached Figure Description

An electrode is inserted under the trapezoidal conductive block 4, and the bolt 5 is tightened, causing the bolt 5 to act downwards on the movable seat 3, which in turn acts downwards on the trapezoidal conductive block 4, causing the trapezoidal conductive block 4 to clamp the electrode downwards. When the electrode is subjected to an outward pulling force, the electrode acts backwards on the trapezoidal conductive block 4. The movable seat 3 guides the trapezoidal conductive block 4 downwards, further clamping the electrode.

[0019] like Figure 1 and 2 As shown, the connector 2 includes a base 21, and a threaded hole 22 is provided at the upper end of the base 21. The bolt 5 is threaded into the threaded hole 22. The threaded hole 22 is used to guide the bolt 5 to move up and down spirally.

A first baffle 33 is fixedly connected to one end of the trapezoidal block 31, and the first baffle 33 is in movable contact with the base 21. Tightening the bolt 5 causes the bolt 5 to act downward on the trapezoidal block 31, which in turn acts downward on the trapezoidal conductive block 4.

The lower end of the second baffle 32 is fixedly connected to the trapezoidal block 31. The second baffle 32 is used to block the base 21 from falling out of the base 21.

[0023] like Figure 1 , 3 As shown in Figure 4, the trapezoidal conductive block 4 includes a pressure plate 41, and a guide surface 42 is provided at the upper end of the pressure plate 41. When the lower part of the pressure plate 41 is subjected to an outward pulling force, the pressure plate 41 slides slightly outward, causing the guide surface 42 to slide down along the trapezoidal block 31. The trapezoidal block 31 acts on the guide surface 42, causing the pressure plate 41 to further act downward on the target electrode.

[0024] Working principle: Insert the electrode into the lower side of the trapezoidal conductive block 4, and then tighten the bolt 5. The bolt 5 acts downward on the movable seat 3, which in turn acts downward on the trapezoidal conductive block 4. The trapezoidal conductive block 4 clamps the electrode downward.
