Detailed description of the invention
With reference to Fig. 1-Figure 11, the integrated composite main shaft of milling car Compositions of metal-working machines of the present utility model, including main spindle box body 1, metal front lid 2, metal rear end cap 3, main shaft shaft core 4, spindle drive 5, locking device 6 and pine tool-broaching mechanism 7.
Wherein, in view of rear end cap 3, spindle drive 5 and pine tool-broaching mechanism 7 not present invention point, and, general prior art all can be used to substitute, therefore, these several parts and mechanism do not illustrate one by one at this.Wherein, spindle drive 5 is by shaft coupling or belt transmission to main shaft, it is provided that the power resources of main shaft, it addition, mair motor has standard to stop function, angle resetting is 0.04 degree.
nullSpecifically describe and improve as follows: on main spindle box body 1, being provided with spindle hole 10，Before drive end bearing bracket 2 and rear end cap 3 are respectively arranged in spindle hole 10、Rear two ends，Drive end bearing bracket 2 and rear end cap 3 are respectively arranged with the axially extending bore coaxial with spindle hole 10，Main shaft shaft core 4 is threaded onto in described spindle hole 10，The front end of main shaft shaft core 4 is supported by fore bearing 81 in the axially extending bore being installed on drive end bearing bracket 2，Fore bearing 81 is arranged on spindle hole 10 front end by fore bearing gland 91，The rear end of main shaft shaft core 4 is supported by rear bearing 82 in the axially extending bore being installed on described rear end cap 3，And encapsulated by rear bearing gland 95，The inner side of drive end bearing bracket 2 is provided with the annular oil cavity 20 coaxial with main shaft，Annular oil cavity 20 connects with hydraulic control channel 21，Annular piston dish 25 is installed on annular oil cavity 20，Annular piston dish 25 connects pulls back and corner origin reference location mechanism，The top of annular piston dish 25 is fixed with first annular fluted disc 26，Circular rotating disc 45 it is coaxially installed with in main shaft shaft core 4，This circular rotating disc 45 is between fore bearing gland 91 and annular piston dish 25，The bottom of circular rotating disc 45 is fixed with the second annular fluted disc 46 can being mutually twisted with first annular fluted disc 26，The front end face of fore bearing gland 91 is the brake contact surface 92 corresponding with the back side of circular rotating disc 45，Position relationship between front end face and the back side of circular rotating disc 45 of fore bearing gland 91 also has when both depart from，There is releasing orientation gap 80，In an embodiment，This releasing orientation gap can be 0.05mm.
Preferentially, with reference to Fig. 3-Fig. 8, first annular fluted disc 26 and the second annular fluted disc 46 lay respectively on annular piston dish 25 and circular rotating disc 45 edge placement, it is formed with inclined-plane deformation mechanism between front end face and circular rotating disc 45 back side of fore bearing gland 91, when the front end face of fore bearing gland 91 is close to, is pressed on to circular rotating disc 45, circular rotating disc 45 center of connection main shaft shaft core 4 deforms downwards axial displacement and compensates.When after brake, the front end face (brake disc) of fore bearing gland 91 is close to circular rotating disc 45, and offset in brake process the impact on bearing axial displacement by the inclined-plane deflection of inclined-plane deformation mechanism, to ensure that brake does not affect the service life of bearing while of firm, turning produces axial drag again and can be born by circular rotating disc, pushes away enhancing axial rigidity by inclined-plane is counter.
Wherein, the described inclined-plane highly preferred embodiment of deformation mechanism is that the center of fore bearing gland 91 is slightly lower, the brake contact ramp structure gradually carried on edge, circular rotating disc 45 is thin slice during deformable, and the center portion thereof position and main shaft shaft core 4 fasten, when second annular fluted disc 46 at edge is upwards pressed by first annular fluted disc 26, the centre of circular rotating disc can deform downwards, making the downward micro-shifting of main shaft shaft core, above structure fabrication is easy, with low cost.
Additionally, further, described pull back and corner origin reference location mechanism is that one end is arranged in the annular oil cavity 20 inside drive end bearing bracket 2, the other end annular Return spring sheet 28 that be connected fixing with annular piston dish 25, on the one hand can pull back when oil pressure is zero the occlusion departed between two fluted discs, on the other hand shell fragment also secures annular piston dish 25 and can only sliding can not rotate, as the benchmark of fluted disc corner.
Certainly, this pull back and corner origin reference location mechanism except can be such as figure in embodiment in addition to, can also is that alternate manner, such as return mechanism is relative with annular oil cavity 20, another hydraulic chamber in opposite direction, and corner origin reference location mechanism can be the mechanism of the guide groove, the guide rail that are such as arranged between piston plate and drive end bearing bracket etc, illustrates the most one by one at this.
It addition, in view of the purpose of this utility model is the structure precision of the integrated composite main shaft improving milling car Compositions of metal-working machines, therefore, further preferably, not only above structure can be improved, it is also possible to other structure is improved, to improve its structure precision from every side.nullSuch as，Main axle structure at the most widely used use BT handle of a knife at present，With reference to each figure，In conjunction with Fig. 9、Figure 10 and Figure 11，When the spindle shaft cored structure that main shaft shaft core 4 is BT handle of a knife，Aforesaid BT handle of a knife refers to the general handle of a knife that tapering is 7:24，The end face of the non-Cutting tool installation manner end of handle of a knife 100 is handle of a knife rear end face 110，The center of handle of a knife rear end face 110 is provided with the frustum of a cone 120，The main shaft shaft core 4 end face near handle of a knife rear end face 110 one end is main shaft shaft core front end face，Main shaft shaft core front end face centre is provided with taper hole 130，The shape of taper hole 130 matches with the frustum of a cone 120，Two symmetrical angle locating slots 150 for angular location in axial direction it are provided with on the circumference of handle of a knife rear end face 110，The angle positioning key 155 corresponding with angle locating slot 150 is had on taper hole 130 outer ledge.Certainly, this handle of a knife can be not limited to above-mentioned BT type structure, it is also possible to is CAT type, SK type, DINd type and other similar specification.
The improvements of this structure are, the side of one of them angle positioning key 155 is the elastic 158 of band keyway 156, evagination apical grafting position 157, evagination apical grafting position 157 and the inwall apical grafting of angle locating slot 150, abutting part 159 on the basis of the opposite side of this angle positioning key 155 is had on the outside of this elastic.
Preferably, described side is the free state width receiving width more than angle locating slot 150 of the angle positioning key 155 of band keyway elastic, and pressured state width is equal to or less than the receiving width of angle locating slot 150.
When handle of a knife being arranged on main shaft use, the frustum of a cone is installed in taper hole, push up under pressure effect in elastic with the mutual of corresponding angle locating slot, benchmark abutting part is made to be in close contact with angle locating slot respective inside, using the angle position of this benchmark abutting part as the benchmark of corner resetting, it is achieved the further corner resetting of high precision.
Certainly, above-mentioned embodiment is not to unique restriction of the present utility model, and other equivalent technical solutions should also be as within the protection domain of the invention.
