The Y-direction cutting force charging assembly is provided with two sets and parallel distribution altogether, and X is loaded to cutting force charging assembly and Z-direction cutting force
Component is provided with a set of, and X is to the X direction guiding rails mounting seat of cutting force charging assembly and the Y of two sets of Y-direction cutting force charging assemblies
It is connected simultaneously to sliding block.
4. a kind of five axles Double swing head planer-type milling machine simulation cutting force loading device according to claim 1, it is characterised in that：
Structural rigidity is fixed with below the Y-direction guide rail mounting seat of the Y-direction cutting force charging assembly and strengthens base, in structural rigidity plus
Reinforcement riser is provided with strong base, two Y-directions are installed are oriented to polished rods reinforcement riser top is parallel, Y-direction is oriented to light
Bar is parallel with Y-direction guide rail, and two Y-directions are connected with an X to guiding polished rod between being oriented to polished rod, and X is led to polished rod is oriented to Y-direction
Perpendicular to polished rod, X is slidably connected cooperations to being oriented to polished rod and Y-direction and be oriented to polished rod, and a cunning is set with guiding polished rod in X
Moving sleeve, sliding sleeve outer tube wall is fixed together with Z-direction column.
5. the application method of five axle Double swing head planer-type milling machine simulation cutting force loading devices described in claim 1, its feature exists
In comprising the following steps：
Step one：Selected one needs five axle Double swing head planer-type milling machines of progress performance test, by simulation cutting force loading device
It is lifted on the workbench of five axle Double swing head planer-type milling machines and is fixed；
Step 2：Machine tool spindle is fixed together with bulb club shaft, then respectively by X to ripple damper tube, Y-direction
Ripple damper tube and Z-direction ripple damper tube are connected with hydraulic oil source, while starting X to hydraulic pressure retaining system, Y-direction hydraulic pressure positive system
System and Z-direction hydraulic pressure retaining system；
Step 3：Set one group of cutting force；
Step 4：Valve port openings of the X to choke valve, Y-direction choke valve and Z-direction choke valve is adjusted respectively, makes X to ripple damper tube, Y
Hydraulic oil suction resistance into ripple damper tube and Z-direction ripple damper tube is equal to set cutting force, recycles torsion to pull
Hand tightens pretension bolt, is equal to the frictional force between ball rod bulb end and sphere base and sphere annular gland set
Cutting force；Because hydraulic oil suction resistance can not be directly read, pressure values can only directly be read by pressure gauge, and pressure values are needed
To be obtained by calculating, during calculation formula is P=F/S, formula, P is pressure values, and F is hydraulic oil suction resistance, and S is setting aperture
Under choke valve valve port cross-sectional area；, can only be straight by torque spanner because frictional force can not directly be read on torque spanner
Connect reading screw-down torque, and screw-down torque needs to obtain by calculating, during calculation formula is M=KF ' d/ μ, formula, M is screwing force
Square, K is tightens force coefficient, and F ' is frictional force, and d is the screw thread nominal diameter of pretension bolt, and μ is coefficient of friction；
Step 5：Start lathe and run procedure, start the process of simulated machine tool, and true simulated machine tool is in stress
Under the conditions of actual motion state, and then test out the machine tool capability under the conditions of current cutting force；
Step 6：Cutting force, repeat step four and step 5 are reset, the machine tool capability survey under the conditions of different cutting force is completed
Examination.
