Loading device and method for reliability test of rolling linear guide rail and ball screw system

Abstract

The invention provides a rolling linear guide and ball screw system reliability test loading device and a method of use, including: , and implement sliding loading. The invention provides a new machine tool performance testing method. After the test loading device is assembled and used with the machine tool to be tested, it can truly simulate the load applied to the linear guide rail and the ball screw pair in the linear feed motion of the machine tool, completely There is no need to consume physical materials and processing tools, which effectively reduces the cost of machine tool performance testing. While ensuring the excellent performance of the machine tool, it also effectively reduces the cost of machine tool manufacturing.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of machine tools, in particular to a loading device and method for reliability testing of rolling linear guide rails and ball screw systems. Background technique [0002] At present, the status of CNC machine tools in the equipment manufacturing industry is becoming more and more significant, and the processing accuracy and processing efficiency have been greatly improved, and they have become indispensable processing equipment in many industries. For machine tool manufacturing enterprises, the higher the reliability of machine tool products, the better the performance of the machine tools they manufacture. Improving the performance of machine tools can increase the price of machine tool products, and at the same time save a sum of maintenance and after-sales service costs. [0003] Before the machine tool is finalized, the performance test of the machine tool is an indispensable link....

Problems solved by technology

Both testing methods have considerable limitations

The first method requires a lot of manpower, material and financial resources

The consumption of machining materials and machine tools is included in the manufacturing cost of the machine tool. Increasing the cost of the product means reducing the market competitiveness of the product. Although this test method is the most reliable test method, it cannot meet the needs of many machine tool companies to reduce costs. profit margin needs

Although the reliability simulation test by computer can greatly reduce the cost and save time, but the reliability of the product will be greatly reduced, because there will be considerable uncertainties and emergencies in the actual operation of the equipment, which are caused by computer Simulate what analog test rigs can't

Although it can reduce costs, it increases the failure rate of machine tools
