A three-axis boring machine simulation cutting force loading device and its use method

Abstract

A three-axis boring machine simulated cutting force loading device and its use method. The device includes a rigid frame, an X-direction position adjustment component, a Y-direction cutting force loading component, a Z-direction position adjustment component and a tool rotation cutting force loading component. The method steps are: Lift the simulated cutting force loading device to the machine tool workbench, adjust and fix the position of the simulated flat rotating plate through the X-direction and Z-directed position adjustment components, and securely connect the simulated flat rotating plate and the boring tool bar on the machine tool flat rotating plate. ; Set a set of cutting forces, and use a torque wrench to tighten the pre-tightening bolts in the cutting force loading assembly in the Y direction and the tool rotation direction, so that the friction force in the cutting force loading assembly is equal to the set cutting force. Since the friction force cannot be read directly, the tightening torque needs to be calculated through the formula M=KFd / μ before reading; start the machine tool and run the processing program to truly simulate the actual operating status of the machine tool under stress conditions and test the current cutting force conditions. Lower machine tool performance.

Description

technical field [0001] The invention belongs to the technical field of machine tool performance testing, and in particular relates to a three-axis boring machine simulation cutting force loading device and a use method. Background technique [0002] At present, the three-axis boring machine is mainly used for boring the inner holes of parts. In many industries, the three-axis boring machine has become an indispensable processing equipment. 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 machine tools is often linked to the performance of machine tools. The better ...

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
