A swinging head rotary table five-axis machine tool simulating cutting force loading device and using method

Abstract

A swing-head turntable five-axis machine tool simulated cutting force loading device and a method of use. The device includes X-direction, Y-direction, Z-direction, turntable rotation steering and swing-head rotation cutting force loading components. By tightening the X-direction and Y-direction respectively , Z-direction, turntable rotation and swing head rotation pre-tightening bolts to achieve cutting force loading. The method steps are: hoist the device to the machine tool turntable, fix the turntable rotation fixed plate to the machine tool turntable, and connect the machine tool tool spindle and The motor shafts of the damping motor are firmly connected; set a set of cutting forces, and tighten the pretightening bolts in the five cutting force loading components with a torque wrench, so that the friction forces in the five cutting force loading components are respectively consistent with the set The specified cutting force is equal. Since the friction force cannot be read directly, the tightening torque needs to be calculated through the formula M=KFd / μ and then read; start the machine tool and run the processing program to truly simulate the actual operating status of the machine tool under stress conditions. , test the machine tool performance under current cutting force conditions.

Description

technical field [0001] The invention belongs to the technical field of machine tool performance testing, and in particular relates to a cutting force loading device for simulating a five-axis machine tool with a swing head and a rotary table and a use method thereof. Background technique [0002] At present, for the swing head rotary five-axis machine tool in the CNC machine tool, the five-axis linkage can meet the high-precision machining of complex curved surface parts, and 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 sit...

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
