Digit Control Machine Tool being carried out aspect reliability testing and evaluation, is generally to adopt field statistics method.In order to make up the test and appraisal of today's numerical control lathe reliability, adopt the sampling period of field statistics method existence long, be subject to environment impacts on inefficacy and the fault data degree of accuracy different from operating personnel's condition, and the more difficult deficiencies such as reliability design desired data that provide, need to carry out the research of the Digit Control Machine Tool accelerated test technology based on laboratory.
Machine tool chief axis is one of nucleus movement parts of Digit Control Machine Tool, and the rigidity of spindle operation and reliability index are occupied very large proportion in the reliability index of Digit Control Machine Tool complete machine is distributed.For this reason, for Digit Control Machine Tool rigidity and reliability test technology, developing a kind of main shaft of numerical control machine tool that can the main shaft stress load of simulated machine tool in typical condition process and load handle of a knife, is one of important research content of Cnc ReliabilityintelligeNetwork Network accelerated test platform construction work.Developing a kind of main shaft of numerical control machine tool simulation loading handle of a knife, is to carry out one of important technical in Cnc ReliabilityintelligeNetwork Network accelerated test and appraisal.
Existing main shaft of numerical control machine tool load test technology and test handle of a knife, be only satisfied with Digit Control Machine Tool Spindle Static state loaded or low speed loading, and this fictitious load load test handle of a knife, can only bear static load or low speed dynamic load, can not bear and run up.
High speed simulation loading handle of a knife of the present utility model is reliability testing technology and the method for evaluating reliability based on engineering test method, invented the loading handle of a knife of a kind of machining center rigidity and the simulation of reliability test main shaft dynamic load, be used for carrying out machining center reliability accelerated test, can realize main shaft of numerical control machine tool dynamic load simulation loading, quick, accurate and quantitative reliability evaluation.
Thereby, the main shaft high speed simulation loading handle of a knife that currently available technology does not also have a kind of machining center rigidity and reliability to use.
Utility model content:
The main shaft High speed load handle of a knife that provides a kind of machining center stiffness test and reliability test to use is provided the purpose of this utility model.
The utility model comprises the HSK High speed load handle of a knife (see figure 1) that a set of machining center is used.
The HSK High speed load handle of a knife that a kind of machining center described in the utility model is used, is characterized in that: comprise HSK cutter hub, end cap, broach shell, forward bearing, reverse bearing, intermediate sleeve, locking nut, sunk screw;
Described HSK cutter hub 1 is mounted on the main shaft of machining center, end cap 2 and broach shell 3 link into an integrated entity by sunk screw 10, broach shell 3 by forward bearing and oppositely bearing and main shaft be connected in can together with turn round, in one end of main shaft, be provided with for fixing intermediate sleeve and locking nut;
Further, the bottom centre of broach shell is provided with the centre bore with sealing screw 9 sealings.Oil in broach shell is from flowing out by centre bore.
Further, forward bearing is more than two, and the scope of radial loaded is larger like this.
Described broach shell 3 can bear axial load and radial load, axial load stress point is positioned near the centre bore position (sealing screw 9) of broach shell 3, radial load stress point can (vertical machining centre or left and right (horizontal Machining centers) moves fine setting, and fine setting displacement is between 20～50mm up and down.
Carrying out axially loading and during radial loaded work, the broach shell 3 after stressed shuts down, and HSK cutter hub 1 continues to keep and spindle synchronous rotation, thereby realize between the main shaft rotating and straight-line feed shaft, realizes dynamic load.
That the utility model is to adapt to is vertical, the main shaft in horizontal Machining centers stiffness test and reliability accelerated test and the demand of feed shaft load test.
The utility model has solved in the test of work in-process heart main axis stiffness and reliability accelerated test, how to find the simulation handle of a knife of adjustable stress point displacement to carry out stiffness test, how to simulate machining center actual condition and between main shaft and feed shaft (comprising X, Y-axis and Z axis), realize the difficult problem that dynamic analog loads.The HSK High speed load handle of a knife that a kind of machining center of the present utility model is used, has convenient operation, simulation actual condition fidelity is high and running speed high.The utility model can directly apply to carries out Cnc ReliabilityintelligeNetwork Network accelerated test, promotes Cnc ReliabilityintelligeNetwork Network level to improve, and the utlity model has significant economic benefit.
