Problems solved by technology

Due to the alignment error when installing the round rod electrode, the machine tool itself also has machining errors, and the standard 3R fixture on the spindle head also has axial errors. It is impossible to adjust the round rod electrode to be concentric with the spindle, which will affect the machining accuracy.

Embodiment Construction

[0008] like figure 1 As shown: 3 is the upper connecting body, 6 is the lower connecting body, a relative pit is processed at the center between the upper connecting body 3 and the lower connecting body 6, and a steel ball 4 is clamped in the opposite pit, and the upper connecting body At least three (four in this embodiment) adjusting bolts 5 are evenly distributed around the connecting body 3 and the lower connecting body 6 .

[0009] There is a boss on the outside of the upper end of the electrode mounting sleeve 10 and is clamped on the inside of the lower connecting body 6. The position is limited by the gland 9, and the gland 9 and the lower connecting body 6 are fixedly connected by bolts. Around the sides of the lower connecting body 6 are provided with adjusting top wires 8 against the electrode mounting sleeve 10 , there are four adjusting top wires 8 and they are evenly distributed on the side of the lower connecting body 6 . The lower end of the electrode mounting...

Abstract

The invention discloses a frock clamp, in particular to an adjustable rotary electrical-discharge machining frock clamp. The frock clamp comprises an upper connector (3) and a lower connector (6), wherein opposite concave pits are arranged at the center between the upper connector (3) and the lower connector (6); balls (4) are clamped in the concave pits; at least three adjustable bolts (5) distributed uniformly are arranged at the peripheries of the upper connector (3) and the lower connector (6); the upper end of an electrode installation sleeve (10) is clamped at the inner side of the lower connector (6); an adjustable top thread (8) pushing against the electrode installation sleeve (10) is arranged around the side edge of the lower connector (6); and the lower end of the electrode installation sleeve (10) is connected with a gland (11) by screw thread. When in installation, the frock clamp is fixed on a 3R frock clamp at the spindle head of a machine tool, and a round-bar electrode is installed at an inner taper hole of the electrode installation sleeve. After the round-bar electrode is installed, the angle and the relative position of the round-bar electrode can be adjusted, thereby improving the coaxiality of the round-bar electrode and a spindle and improving the machining accuracy.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an adjustable rotary electrical discharge machining tooling fixture. Background technique [0002] When the EDM machine tool is used to rotate the product axially, the round rod electrode is installed on the spindle of the machine tool through the standard 3R fixture. When working, the round rod electrode and the spindle rotate together to perform EDM on the workpiece. Due to the alignment error when installing the round rod electrode, the machine tool itself also has machining errors, and the standard 3R fixture on the spindle head also has axial errors. It is impossible to adjust the round rod electrode to be concentric with the spindle, which affects the machining accuracy. Contents of the invention [0003] The object of the present invention is to provide a fixture which can adjust the installed round rod electrode and improve the coaxiality between the round rod electrode and the main...
