Description of drawings
The cutaway view of the clamping device that provides for preferred embodiment of the present invention shown in Figure 1.
The cutaway view of the clamping device that provides for another preferred embodiment of the present invention shown in Figure 2.
The specific embodiment
To combine Fig. 1 and Fig. 2 in the preferred embodiment of the present invention below, the technical scheme in the embodiment of the invention will be carried out clear, intactly description.
See also Fig. 1, preferred embodiment of the present invention provides a kind of clamping device, and it is fixed on the base 1 of complex milling machine tool so that rotary table 2 is clamped.This clamping device comprises first cushion block 30, first back-up block 31, projection 32, clamping element 33, bolt 34, flexible member 35, oil cylinder 36, second cushion block 37, second back-up block 38, sleeve 39 and locking element 40.
This first cushion block 30 removably is connected on this base 1 through a plurality of bolts with this first back-up block 31.Wherein, this first cushion block 30 is arranged between this base 1 and this first back-up block 31.
This projection 32 is through being bolted on this first back-up block 31.Can adjust the position of these projection 32 relative these clamping elements 33 through the thickness that changes this first cushion block 30; Inhomogeneous to avoid this clamping element 33 when this rotary table 2 is clamped, clamping force to take place, and then cause tight or cause the damage of this clamping element 33 to 2 clampings of this rotary table.
This clamping element 33 comprises first clamping plate 331 and second clamping plate 332 that match with these first clamping plate 331.Offer first accepting groove on these first clamping plate 331, offer second accepting groove that aligns mutually with this first accepting groove on these second clamping plate 332.This first accepting groove matches with ccontaining this flexible member 35 with this second accepting groove.Through changing the thickness of this first cushion block 30; Make this projection 32 between these first clamping plate 331 and this second clamping plate 332; And when these first clamping plate 331 and second clamping plate, 332 closures clamped this rotary table 2, these first clamping plate 331 and second clamping plate 332 also clamped this projection 32 simultaneously.
The head of this bolt 34 is fixed on the end of these first clamping plate 331 away from these second clamping plate 332, and the bar portion of this bolt 34 passes these first clamping plate 331 and this second clamping plate 332 and extends outside these second clamping plate 332.
This flexible member 35 is preferably the dish spring, and it is set in the bar portion of this bolt 34, and this flexible member 35 is placed in this first accepting groove and this second accepting groove.The two ends of this flexible member 35 support respectively on these first clamping plate 331 and this second clamping plate 332, think that this clamping element 33 provides elastic force.
This oil cylinder 36 is set in the bar portion of this bolt 34.This oil cylinder 36 comprises oil cylinder body 361 and the piston 362 that matches with this oil cylinder body 361.This oil cylinder body 361 supports in the side of these second clamping plate 332 away from these first clamping plate 331.The oil circuit that offers hydraulic fluid port 363 on this oil cylinder body 361 and be connected with this hydraulic fluid port 363.This hydraulic fluid port 363 is connected with fuel tank, to this oil cylinder 36 hydraulic oil is provided by fuel tank.Form airtight oil pocket between this piston 362 and this oil cylinder body 361, hydraulic oil gets into this oil pocket through oil circuit.Under the effect of oil pressure, this oil cylinder body 361 separates with this piston 362, and therefore, this fuel tank body 361 can promote these clamping element 35 closures and compress this flexible member 35, with this projection 32 of clamping and this rotary table 2.When the hydraulic oil oil return, the hydraulic oil in this oil pocket reduces, and this oil cylinder body 361 direction to this piston 362 under the effect of these flexible member 35 elastic forces moves.Therefore, these clamping element 33 releasings are to the clamping of this projection 32 and this rotary table 2.
This second cushion block 37 removably is connected on this first back-up block 31 through a plurality of bolts with this second back-up block 38.Wherein, this second cushion block 37 is arranged between this first back-up block 31 and this second back-up block 38.Be convexly equipped with a baffle plate 381 on this second back-up block 38, offer a through hole on this baffle plate 381.This baffle plate 381 is used to support this sleeve 39 and this bolt 34.The distance between this baffle plate 381 and this oil cylinder 36 can be adjusted through the thickness that changes this second cushion block 37, thereby the volume of this oil cylinder 36 can be regulated.
This sleeve 39 is set in the bar portion of this bolt 34 and is arranged in the through hole of this baffle plate 381 slidably and supports on this piston 362.
This locking element 40 comprises nut 41 and locking nut 42.This nut 41 and this locking nut 42 are locked with the bar portion of this bolt 34 successively mutually.Therefore, moving of this bolt 34 can drive this sleeve 39 and this locking element 40 moves jointly.
When this complex milling machine tool of needs carried out milling to workpiece, the hydraulic oil of controlling in this fuel tank flowed in the oil pocket of this oil cylinder 36, thereby this oil cylinder body 361 is moved to the direction of this clamping element 33 through this hydraulic fluid port 363, oil circuit.These first clamping plate 331 and this second clamping plate 332 these flexible members 35 of compression, and an end of these first clamping plate 331 and these second clamping plate 332 clamps this projection 32, and the other end clamps this rotary table 2, thereby reaches the effect of this rotary table 2 of locking.
When this complex milling machine tool of needs carries out turning to workpiece; The hydraulic oil of controlling in this oil pocket refluxes; This flexible member 35 discharges elastic potential energy so that these first clamping plate 331 are separated with these second clamping plate 332; Therefore, this rotary table 2 is separated with this clamping element 33, makes this rotary table 2 be in released state.
For this flexible member 35 and the pressure that this oil cylinder 36 produces are complementary, an adjustment pad can be set respectively in this first accepting groove and this second accepting groove, the two ends of this flexible member 35 support respectively on said adjustment pad.
See also Fig. 2, the difference of the structure of the clamping device of another preferred embodiment of the present invention and the structure of above-mentioned preferred embodiment is: this clamping device only comprises a cushion block 50 and back-up block 51, has save projection 32 simultaneously.This cushion block 50 removably is connected on this base 1 through a plurality of bolts with this back-up block 51.Wherein, this cushion block 50 is arranged between this base 1 and this back-up block 51.Be convexly equipped with a baffle plate 511 on this back-up block 51, offer a through hole on this baffle plate 511.This baffle plate 511 is used to support this sleeve 39 and this bolt 34.The distance between this baffle plate 381 and this oil cylinder 36 can be adjusted through the thickness that changes this cushion block 50, thereby the volume of this oil cylinder 36 can be regulated.
This clamping device is controlled clamping and release to this rotary table 2 through the mode of hydraulic pressure, and its clamping force is bigger, and stability is higher relatively, therefore, has improved the reliability of complex milling machine tool work.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
