Abstract

The invention discloses a simulated vibration cutting impact cutter falling experimental device and a working method thereof. The device comprises a worktable, a clamp, a vibration cutting device anda control device. The vibration cutting device comprises a cutter falling module and a vibration generating module. The cutter falling module comprises a cutter, a cutter pressing piece, a cutter falling slide bar, a cutter falling shell, a spring bracket and a spring. The vibration generating module comprises a slide block, a slide block supporting plate, a slide block pin straight-side self-lubricating bearing, a connecting rod, a flanged-side self-lubricating bearing, a short shaft turntable, a long shaft turntable and a vertical bearing seat. The simulated vibration cutting impact cutter falling experimental device is provided with the vibration generating module and the cutter falling module, can simulate a complete vibration cutting process, and can achieve a complete vibration cutting cycle at a time, can set different cutting parameters that can be input by a program and can be modified conveniently, and improves the level of automation by means of the control device .

Description

technical field [0001] The invention belongs to the technical field of vibration cutting and processing, in particular to an experimental device for simulating vibration cutting impact tool drop. Background technique [0002] Vibration cutting is an advanced processing technology developed in the middle of the 20th century, that is, by imposing some regular and controllable vibration on the cutting tool, the tool and the workpiece have discontinuous contact, so that the cutting speed, back Periodic changes in the amount of knife engagement have changed its processing mechanism and fundamental changes have taken place in the traditional cutting mode. Vibration cutting is a cutting form with great potential value. How to make more and more effective use of this cutting method has become a research content that many experts at home and abroad pay attention to. The study of its mechanism is the theoretical premise of whether this technology can be widely used in actual producti...

AI Technical Summary

Problems solved by technology

[0003] Through reviewing the literature, we learned that most of the existing equipment performs cutting and observation records under high-frequency conditions, and it is difficult to capture a complete cutting cycle.

Although some impact test benches can perform simulated cutting, they only perform one impact cutting, which cannot simulate the entire cutting process well, and some cutting parameters cannot be well controlled.
