Description
Technical field
The present invention relates to a kind of sweep-saw, especially a kind of fuselage can be with respect to the sweep-saw of base plate rotation.
Background technology
Sweep-saw is in to workpiece process, and relating to cuts sth. askew cuts, and needs often to adjust the angle of inclination of fuselage and base plate, and this just needs a kind of locking device to clamp or to unclamp fuselage and base plate apace, carries out the adjusting of angle.Prior art has disclosed various locking devices, disclosed a kind of locking device as United States Patent (USP) 5617638, it is by assembly wrench on the screw rod that connects fuselage and base plate, operation spanner rotary screw unclamps or locks fuselage and base plate, but the spanner of this jockey acts directly on the screw rod, make that the movement travel of each operation spanner screw rod is little and the gearratio of this structure is little, thus make finish unclamp or the time of fuselage and base plate consumption of lock long; Equally, must be longer for the arm of force that makes the laborsaving then spanner of operator, this just requires bigger operating space, is unfavorable for that sweep-saw develops to miniaturization.And for example another Chinese utility model patent specification notification number 2404653Y has disclosed a kind of locking device, it comprises the screw rod that connects fuselage and base plate, and the operation board that is arranged on the circle on the screw rod, thereby the moving screw rod rotation of rotary manipulation dribbling is unclamped or has been compressed fuselage and base plate, and this locking device has the defective that gearratio is little, operation is wasted time and energy equally.
Summary of the invention
Technical problem to be solved by this invention: provide a kind of sweep-saw, it is big to have gearratio, swift to operate, labour-saving locking device.
Technical scheme of the present invention is: a kind of sweep-saw, comprise fuselage, can be described relatively the base plate of fuselage rotation, the locking device that connects the connector of described fuselage and described base plate and be used to loosen or clamp described fuselage and base plate, wherein said locking device comprises the operating parts of a band sun gear, planetary gear set, the pedestal of planet carrier and band ring gear, described planet carrier and described connector the two one of them are provided with internal thread hole, another is provided with corresponding external screw thread, and described planet carrier is threaded with described connector.Wherein, be provided with flexible member between described operating parts and the described pedestal.
Sweep-saw of the present invention makes this locking device have bigger gearratio owing to adopt the locking device of band epicyclic transmission mechanism, and is swift to operate laborsaving and have a less size.

The specific embodiment
With reference to shown in Figure 1, a kind of sweep-saw comprises fuselage 1, base plate 2, bolt 3, pressing plate 4 and locking device 5.The bottom of fuselage 1 is provided with installing hole 12.Base plate 2 is provided with through hole 22.Pressing plate 4 is provided with through hole 42.Bolt 3 is that an end has boss 32, and the other end has the plain bolt of external screw thread 34.
With reference to Fig. 2 to shown in Figure 4, the operating parts 54 that locking device 5 comprises, flexible member 56, planetary gear set 58, planet carrier 60, needle bearing 70, pad 72,74, collar 76 and the pedestal 80 formed by three planetary gears.Operating parts 54 comprises that a cross section is that first main body, 51, the first main bodys, 51 bottom centre of U-shaped are provided with sun gear 52, the first main bodys 51 ring wall inboards and are provided with annular groove 53.Flexible member 56 is a pot shape, and the bottom of a pan is provided with centre bore 57.Planet carrier 60 comprises disc-shaped main body 61, and main body 61 1 sides are provided with three supports 62, and the opposite side center is provided with cylinder 63, and the center of planet carrier 60 also is provided with screwed hole 64 and is threaded with the external screw thread 34 of bolt 3.Pedestal 80 comprises that a cross section is that second main body, 81, the second main bodys, 81 bottom centre of U-shaped are provided with through hole 82, the second main bodys 81 ring wall inboards and are provided with ring gear 83, the second main bodys 81 ring wall arranged outside the annular shaft shoulder 84 is arranged.
Locking device after the installation is referring to shown in Figure 5, and the cylinder 63 of planet carrier 60 passes pad 72 downwards successively, needle bearing 70, and the centre bore 82 of the centre bore of pad 74 and pedestal 80 rotatably is housed in the inner chamber of pedestal 80.Planetary gear set 58 rotatably is socketed on the support 62 of planet carrier 60.Operating parts 54 rotatably is socketed on the pedestal 80, the ring wall inboard of its first main body 51 and main body second ring wall outside loose fit of pedestal 80, collar 76 is housed in the annular groove 53 and is resisted against and makes on the annular shaft shoulder 84 that operating parts 54 and pedestal 80 axially can not break away from.The centre bore 57 of flexible member 56 is socketed on the sun gear 52 of operating parts 54, arches upward and be resisted against on the operating parts 54 in its middle part, and the edge is resisted against on the pedestal 80.The sun gear 52 of the operating parts 54 after the installation and planetary gear set 58 engagements, planetary gear set 58 meshes as shown in Figure 6 with the ring gear 83 of pedestal 80.
When locking the operation of fuselage 1 and base plate 2, the end that bolt 3 is provided with external screw thread 34 upwards passes the through hole 42 of pressing plate 4 successively, and the through hole 22 of base plate 2 and the installing hole of fuselage 1 12 backs and the screwed holes 64 on locking device 5 planet carriers 60 align.To the operating parts 54 of locking direction rotating locking apparatus 5, because the frictional force of flexible member 56 between operating parts 54 and pedestal 80 makes pedestal 80 and operating parts 54 rotations, locking device 5 was done as a whole rotation and was threaded with bolt 3 this moment.When the lower surface that locking device 5 screw into pedestal 80 contacts with fuselage 1, produce frictional force between pedestal 80 and the fuselage 1, this frictional force increases along with the further precession of locking device 5.Be further rotated operating parts 54, when the frictional force between flexible member 56 and operating parts 54 and the pedestal 80 can not overcome frictional force between pedestal 80 and the fuselage 1 and drives pedestal 80 rotations, operating parts 54 relative pedestal 80 rotations, its sun gear 52 drives planetary gear set 58 rotations and then drives planet carrier 60 rotations, thereby makes the screwed hole 64 of planet carrier 60 to screw locking fuselage 1 and base plate 2 with bolt 3 fast.
When unclamping the operation of fuselage 1 and base plate 2, to unclamping direction rotary manipulation spare 54, because the frictional force between pedestal 80 and the fuselage 1 makes operating parts 54 relative pedestals 80 rotate greater than the frictional force between flexible member 56 and operating parts 54 and the pedestal 80, its sun gear 52 drives planetary gear set 58 rotations and then drives planet carrier 60 rotations, unclamp fuselage 1 and base plate 2 thereby make the screwed hole 64 of planet carrier 60 to unscrew with bolt 3 fast, just can carry out the adjusting of fuselage 1 and base plate 2 angles this moment.
In the present invention, bolt 3 can substitute with other connectors, is equipped with the screw rod of screw thread as two ends, and an end cooperates with nut, and the other end cooperates with locking device 5.Equally, the external screw thread 34 that is arranged on the internal thread hole 64 on the planet carrier 60 among the present invention and is arranged on bolt 3 or other connectors can transposition, as on the cylinder 63 of planet carrier 60, external screw thread being set, tapped blind hole or the through hole that matches with this external screw thread is set in the end of bolt 3 or other connectors.Flexible member 56 also can be set to other shapes, is the sheet of arc as the cross section of being with centre bore.
