The technical scheme of the device includes that a support is fixedly connected onto a spindle case, a cylinder is fixedly connected onto the support, a groove is arranged in the middle of the cylinder, a damping plate is arranged in the groove, pistons are respectively mounted on two sides of the damping plate in the cylinder, end covers are arranged at two ends of the cylinder, and an oil inlet and an oil outlet are arranged on the end covers. The hydraulic damping control device has the advantages that the device is simple in structure and reliable in operation, external force applied to the damping plate of a spindle is simultaneously applied from two sides so that consistent damping force is symmetrically applied, deformation of the damping plate is avoided, and accordingly the spindle is stable in operation.
Description
Technical field
The utility model belongs to machine control unit, particularly numerical control of machine tools main axle hydraulic pressure damping control apparatus.
Background technology
The certain damping of the on-stream increase of machine tool chief axis reaches braking fast in the rotation at a high speed, reaches the purpose of weakening when milling.Existing technology is to be provided with brake disc on main shaft, withstands brake disc with an oil cylinder in the side pressurization of dampened disk, realizes the damping state and the braking state of machine tool chief axis.This structural damping dish discontinuity, just a side is stressed, and the dampened disk easy deformation influences the main shaft smooth rotation.
Goal of the invention
The purpose of this utility model just provides the numerical control of machine tools main axle hydraulic pressure damping control apparatus that brake disc both sides on a kind of main shaft are provided with hydraulic cylinder.
The solution that realizes the utility model purpose is to comprise main spindle box 1, main shaft 2, be fixed with dampened disk 3 on the main shaft 2, particularly be fixed with support 10 on main spindle box 1, be fixed with cylinder body 9 on the support 10, there is groove the centre of cylinder body 9, dampened disk 3 is arranged in the groove, the both sides of dampened disk 3 respectively are equipped with piston 7 in the cylinder body 9, and the two ends of cylinder body 9 are provided with end cap 5, and end cap 5 is provided with oil inlet and outlet 11.
The one side that piston 7 contacts with dampened disk 3 is provided with friction plate 8.
The utility model has the advantages that simple in structurely, reliable operation applies for the external force of main shaft dampened disk simultaneously from both sides, the damping force of being given, and size is consistent, and symmetry applies, and dampened disk is indeformable, thereby makes spindle operation steady.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a hydraulic control schematic diagram of the present utility model.
The specific embodiment
On machine tool chief axis 2, be installed with dampened disk 3, dampened disk 3 rotates with main shaft 2, on main spindle box 1, be installed with support 10 by screw, be installed with hydraulic cylinder 9 on the support 10, the centre of hydraulic cylinder 9 has a groove, in this groove, put into dampened disk 3, two pistons 7 are arranged on the both sides of dampened disk 3, and be installed in the cylinder barrel of hydraulic cylinder 9, in order to increase frictional force, on piston 7, designed wearing piece 8, friction plate 8 is installed in the side of piston 7 by dampened disk 3, be provided with a grade limit in the connection place between wearing piece 8 and the piston 7, to guarantee linking intensity, the opposite side of piston 7 is oil pockets, the two ends of hydraulic cylinder 9 are provided with end cap 5, end cap 5 is connected as a single entity by screw 6 and hydraulic cylinder 9, and turnover oil pipe 11 is located on the end cap 5, and is communicated with oil pocket.
As shown in Figure 2, after the turnover oil pipe 11 of oil cylinder 13 passes through a main oil pipe, be connected with the B1 mouth of magnetic valve F1 and the B2 mouth of magnetic valve F2 respectively, the T1 mouth of magnetic valve F1 and the T2 mouth of magnetic valve F2 are communicated with and are communicated with fuel tank 15 by overflow valve Y2, the A1 mouth of magnetic valve F1 and the A2 mouth of magnetic valve F2 are closed, the P1 mouth of magnetic valve F1 is communicated with the P2 mouth of magnetic valve F2, simultaneously, the P1 mouth of magnetic valve F1 is connected to Pressure gauge 14, the P1 mouth of magnetic valve F1 also is connected with oil pump 12 by overflow valve YI, oil pump 12 is connected with motor M, and oil pump 12 also links to each other with fuel tank 15 by filter.
Hydraulic control is such when free state, the DT4 energising on the magnetic valve F2, and the spool of DT4 band is left, be that B2 mouth and T2 mouth are connected, the spool of magnetic valve F1 is failure to actuate, and system pressure oil is by the direct oil sump tank 15 of overflow valve Y2, oil cylinder piston 7 is failure to actuate, and dampened disk 3 just is in free state; When clamped condition, the DT1 energising on the magnetic valve F1, the spool of DT1 band is to the right, be that B1 mouth and P1 mouth are connected, the spool of magnetic valve F2 is failure to actuate, and at this moment, hydraulic oil is by oil pump 12, overflow valve YI, advancing the B1 mouth by magnetic valve F1 from the P1 mouth again goes out, enter oil cylinder 13 by turnover oil pipe 11, promote piston 7 actions, the system pressure maximum, piston 7 clamps dampened disk 3, and dampened disk 3 just is in clamped condition; When damping state, DT2 energising on the magnetic valve F1, the spool of DT2 band left, be that B1 mouth and TI mouth are connected, DT3 energising on the magnetic valve F2 simultaneously, the spool of DT3 band to the right, be that B2 mouth and P2 mouth are connected, at this moment, hydraulic oil is by oil pump 12, overflow valve YI advances the B2 mouth by magnetic valve F2 from the P2 mouth again and goes out, part hydraulic oil advances the T1 mouth by magnetic valve F1 from the BI mouth and goes out, get back to fuel tank 15 by overflow valve Y2 again, another part hydraulic oil enters oil cylinder 13 by turnover oil pipe 11, promotes piston 7 actions, because an effect that distributes hydraulic oil is arranged, system remains an adjustable pressure, and 7 pairs of dampened disks of piston 3 produce certain frictional resistance, and dampened disk 3 just is in damping state.
