Embodiment 1

[0029] This embodiment provides an electrode clamping device, including: a fixed tube 1, a guide sleeve 2, a movable bracket 5, a fixed bracket 7 and a fastening device; the fastening device is arranged in the fixed tube 1, and the fixed bracket 7 is fixed in On the inner wall of the fixed tube 1, the movable bracket 5 is installed in the fixed tube 1 and can move along the axial direction. A compressed spring is provided between the fixed bracket 7 and the movable bracket 5, and the guide sleeve 2 is installed on the fixed tube 1. At the opening of the guide sleeve 2 is provided with a guide tube 19, and the fixed tube 1 is provided with an adjustment hole 20. The inner diameter and length of the guide tube 19 in the guide sleeve 2 are serialized.

Embodiment 2

[0031] As a further limitation to embodiment 1, the fastening device includes: shaft A8, roller A9, shaft B10, roller B11, friction plate 12, slider 13, locking spring 15, shim 16; roller A9 is fixed on the shaft A8, the roller B11 is fixed on the shaft B10, and the shafts A8 and B10 are respectively installed in the guide grooves on both sides of the movable support 5 and the fixed support 7; the slider 13 passes through the shaft A8, and the pin 14 is inserted in In the hole of the axis A8 and the guide groove of the slider 13, the slider 13 moves relative to the axis of the axis A8, and the friction plate 12 is arranged between the slider 13 and the roller A9; a gasket is also installed on the axis A8 16 and a locking spring 15, the locking spring 15 is located between the slider 13 and the washer 16, and the locking nut 17 is threadedly connected to the axis A8 next to the washer 16. The fixed support 7, the movable support 5, and the sliding block 13 are provided with guid...

Embodiment 3

[0035] In this embodiment, in order to prevent the clamped electrode from sliding down naturally due to gravity, the guide tube 19 is provided with an annular groove 18, the rubber ring 4 is installed in the annular groove 18, and the guide sleeve 2 is wrapped around the rubber ring 4.

[0036] In order to improve the positioning accuracy, the fixed tube 1 and the guide sleeve 2 are positioned on the conical surface, and the guide sleeve 2 and the fixed tube 1 are fixed by the threaded connection of the fastening nut 3 and the fixed tube 1.

Abstract

The invention discloses an electrode clamping device. The electrode clamping device comprises a fixed pipe, a guiding sleeve, a movable support, a fixed support and a fastening device; the fastening device is arranged in the fixed pipe, the fixed support is fixed to the inner wall of the fixed pipe, the movable support is installed in the fixed pipe and can move in the axis direction, a main spring is arranged between the fixed support and the movable support, the guiding sleeve is installed at an opening of the fixed pipe, and a guiding pipe is arranged on the guiding sleeve. The electrode clamping device meets the requirements for rapid positioning, clamping and the like of an electrode, and the electrode can be adjusted continuously in the axis direction thereof.

Description

Technical field [0001] The invention belongs to the technical field of special processing, and is specifically a clamping device for fixing and adjusting electrodes. Background technique [0002] Spindle clamps and tool holders are important tool components to realize tool positioning and clamping in machining. They have the advantages of rapid positioning, convenient clamping, and automatic replacement. In conventional machining, the cutting tool is a cutting tool, matched with a standard tool holder, and fixedly installed on the spindle. In EDM, the electrode is used as a tool to process materials. The shape of the electrode is various, and the size ranges from the macro-normal size to the micro-machining size. Commercial machine tools are solved by installing universal fixture components on the spindle, such as common EROWA fixtures, 3R fixtures, and universal chucks. In the field of EDM micro-machining, due to the very small diameter of the electrode, the loss is relatively...
