A vertical numerically controlled milling machine simulating cutting force loading device and using method

Abstract

A vertical CNC milling machine simulated cutting force loading device and a method of use, including an X-direction cutting force loading component, a Y-direction cutting force loading component, a Z-direction cutting force loading component and a torque loading component. The steps to use it are: hoist the simulated cutting force loading device to the machine tool workbench for fixation, secure the machine tool tool spindle to the center piece rod, connect the Z-direction corrugated damping tube to the hydraulic system, and start the hydraulic pressure maintaining system. ; Set a set of cutting forces by adjusting the tightening of the bolts and sliders and adjusting the opening of the throttle valve, start the machine tool and run the processing program, truly simulate the actual operating status of the machine tool under stress conditions, and test the current Machine tool performance under cutting force conditions. The device and its use method can truly simulate the stress conditions during the actual processing of the machine tool without consuming physical materials and processing tools, effectively reducing the cost of machine tool performance testing, ensuring excellent machine tool performance while reducing machine tool manufacturing costs.

Description

technical field [0001] The invention belongs to the technical field of machine tool performance testing, and in particular relates to a vertical numerically controlled milling machine simulating cutting force loading device and a using method. Background technique [0002] At present, for the vertical CNC milling machine in the CNC machine tool, the high-precision machining of more complex parts can be satisfied through three-axis linkage, and it has become an indispensable processing equipment in many industries. Due to different machine tool manufacturers, the machine tool products of each machine tool manufacturer are often different in performance. Due to the differences in machine tool performance, the actual processing capabilities of machine tools are also significantly different. For machine tool purchasing enterprises, they all hope to be able to purchase machine tool products with better performance at a lower price, but the actual situation is that the price of ma...

Problems solved by technology

[0004] At this stage, there are mainly two ways to realize machine tool performance testing. The first is to realize the actual processing of materials by the machine tool, and the second is to realize the machine tool processing process by computer simulation; the machine tool through the first method Performance testing requires the consumption of a large amount of material objects and processing tools, and the price of processing tools is very expensive. Often a performance test process requires several processing tools, and the above costs are included in the manufacturing cost of the machine tool, but this The machine tool performance test method is the most reliable, which can ensure that the machine tool has the best performance after leaving the factory. The disadvantage is that the manufacturing cost of the machine tool is high; the machine tool performance test through the second method, although the test cost is very low, but the test reliability It is also very low. The computer simulation is the ideal processing process, but the actual processing process is uncertain. Even if the performance test is completed in the computer simulation, the machine tool still cannot avoid failures in the actual processing process. occurs, although the manufacturing cost of the machine tool is reduced, and the performance of the machine tool is also sacrificed
