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

Abstract

The invention provides a reliability test loading device for a rolling linear guide rail and ball screw system and a using method thereof. The reliability test loading device for the rolling linear guide rail and ball screw system comprises an X-direction load loading assembly, a Y-direction load loading assembly and a Z-direction load loading assembly, and realizes a mode of uniform stress in theY-direction and the Z-direction and sliding loading. A novel machine tool performance test method is provided. After the test loading device is assembled and used with a machine tool to be tested, the load application on a linear guide rail and a ball screw pair in the linear feeding movement of the machine tool can be truly simulated without consuming material objects and machining tools, the machine tool performance test cost is effectively reduced, and the machine tool manufacturing cost is effectively reduced while the excellent performance of the machine tool is ensured.

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
