An Adaptive and Adjustable Combined Tool Electrode Device

Abstract

The invention provides an adaptive regulating type combined tool electrode device, which is mainly used for matching with ultrasonic vibration grinding electrical discharge machining of high-volume fraction SiCp / Al composite materials. The adaptive regulating type combined tool electrode device comprises a threaded rod fastening screw 1, an electrode base frame 2, a dial fastening screw 3, a threaded rod 4, a threaded sleeve 5, a dial 6, a spring 7, a diamond mounting base 8, a diamond fastening screw 9, a diamond stick 10 and a red copper processing block 11. By utilizing the spring structure, fine tuning is performed by virtue of adaptive feed of a machine tool spindle so as to realize adaptation, the principle that the dial rotates to convert into a linear motion is used for quantitative regulation of the precompressed length of the spring, and the adaptive regulation of the spring is matched with the quantitative regulation of the precompressed length of the spring, so that the coordination of the corrosion removing speed of two composite phases in the composite materials is realized. The adaptive regulating type combined tool electrode device has the advantages of adaptation to coordination of the processing speed, high working efficiency, long service life, capability of replacement and low maintenance cost.

Description

technical field [0001] The invention belongs to the field of processing devices and machinery, and in particular relates to an self-adaptive and adjustable combined tool electrode device. Background technique [0002] In engineering applications, SiCp / Al composite materials have excellent properties such as low expansion coefficient, high specific stiffness, low density and high wear resistance, and have begun to replace aluminum alloy and titanium alloy materials to a certain extent, and are used in aviation, electronics and automobiles, etc. industry. However, with the increase of low-conductivity and high-hardness SiC reinforcement phases (hardness second only to diamond) in composite materials, the previous low-volume fraction SiCp / Al processing methods are no longer suitable for high-volume fraction SiCp / Al. Aiming at the high volume fraction SiCp / Al, the latest ultrasonic vibration grinding discharge processing method is proposed, so it is very necessary to design a c...

Problems solved by technology

However, the erosion speed of the two functions is not coordinated. The tool electrode with a fixed connection between copper / graphite and the grinding block often has a slow erosion phase during processing, which limits the overall erosion speed, resulting in waste of processing time. less efficient

[0009] (2) The utilization rate of the fixed-connection combined electrode is low and the maintenance cost is high

[0010] Although the copper / graphite and grinding block fixed connection combined electrode has the feature of being replaceable, the amount of wear of the copper / graphite and the grinding block is different during processing.

The size of processing blocks such as red copper / graphite and grinding blocks produced in batches is fixed. Due to the severe wear of certain types of processing blocks during processing, all such processing blocks need to be replaced, or even the entire electrode needs to be replaced. The utilization rate is not high, and the follow-up electrode maintenance is expensive
