Removing mechanism for tailstock center of machine tool

Abstract

The invention discloses a removing mechanism for a tailstock center of a machine tool. The removing mechanism comprises a sleeve and a tailstock body, wherein the tailstock body sleeves the outer side of the sleeve; a first end cover is fixedly arranged on the front end of the tailstock body; the sleeve is internally provided with a mandrel, a first ejector rod, a second ejector rod, a piston and a sealing cover; a second end cover is fixedly arranged on the rear end of the sleeve; the second end cover sleeves the outer side of the piston; a third end cover is fixedly arranged on the front end of the sleeve; a first oil chamber is formed among the sleeve, the sealing cover and the piston; a second oil chamber is formed among the sleeve, the piston and the third end cover; the piston is provided with oil transporting holes which are respectively communicated with the first oil chamber and the second oil chamber; the oil transporting holes are communicated with an external oil pump; the tailstock body is provided with a limiting mechanism which is used for adjusting the motion stroke of the sleeve. The removing mechanism has the advantages of compact structure and capabilities of conveniently and efficiently removing the tailstock center, improving the efficiency of changing the tailstock center of the machine tool, improving the automation degree and reliability of the machine tool, prolonging the service life of the machine tool and reducing the use cost of customers.

Description

technical field [0001] The invention relates to a machine tool accessory, in particular to a dismantling mechanism for the top end of a machine tool tailstock. Background technique [0002] With the rapid development of industries such as automobiles, internal combustion engines, aerospace, shipbuilding, military appliances, general machinery, pumps and valves, and reducers, and the continuous progress of high-speed processing technology, the automation, reliability and use of machine tools in various domestic related industries Life expectancy requirements continue to increase. For some machine tools that need to process long-axis parts (such as piston rods and gear shafts), it is often necessary to use a tailstock to improve machining accuracy during finishing. The tip of the tailstock is a key component of the tailstock. Often need to be replaced, the life of the tailstock tip and the convenience of the tailstock tip replacement directly affect the automation degree of t...

Problems solved by technology

For traditional machine tool tailstocks, threads and nuts are reserved at the end of the tailstock tip. During use, workers can only manually rotate the nuts and remove the tailstock tip. This manual removal of the tailstock tip is not only time-consuming It is laborious, and the thread is easy to wear, which makes the tailstock tip unusable, reduces the automation and reliability of the machine tool, and increases the user's later use cost
