Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention made concrete introduction.
Referring to figs. 1 through shown in Fig. 5, the Working head quick-changing mechanism of inventive article machine, toolroom machine includes main part 2 and work
Head, main part 2 is provided with work head mounting seat 1, work head mounting seat 1 is provided with draw-in groove 4, and the first end that works is provided with card
6, dop 6 is connected on draw-in groove 4, and dop 6 is provided with stop pin 10, and mounting seat is provided with lock hole 16, by will lock
Rationed marketing is inserted lockhole and work 3 is locked on main part 2.The effect of draw-in groove 4 is to position and spacing, and it is for by dop 6
Location is working in head mounting seat 1 with spacing.Restriction stop pin 10 and lock hole 16 are used for cooperating and dop 6 are fixed on work
Make in head mounting seat 1.
The present invention is not intended to toolroom machine type, and the type of work 3, and its toolroom machine can be shank grass machine, work
Work 3 can be Soil loosening tool or rake grass cutter.In the present embodiment, illustrate with this.But those skilled in the art should
Noting, the present invention still can apply in other toolroom machines meeting the principle of the invention and work 3.
The present invention is in addition to draw-in groove 4, it is also possible to being provided with block 5 in work head mounting seat 1, block 5 is for when dop 6
Dop 6 position is positioned when being connected on draw-in groove 4.So, by coordinating while draw-in groove 4 and block 5, can be by more preferable for dop 6
Ground carries out location with spacing.Operation handle 11 connects stop pin 10 by connecting pin 12.
Stop pin 10 is set on dop 6 and passes hole 15, spring 8 one end through hole, spring 8, stop pin 10 through stop pin
Being against on dop 6, spring 8 other end is against on stop pin.Being provided with collar 13 on stop pin, spring 8 one end is against dop 6
On, spring 8 other end is against on collar 13.It is provided with rib block 9 on stop pin, dop 6 is provided with long strip type hole 14, when rib block
During 9 entrance long strip type hole 14, stop pin is locked in lock hole 16；When rib block 9 is outside in long strip type hole 14, stop pin and lock
Determine hole 16 to disengage.
It is schematically illustrate with the grass rake mechine that loosens the soil below.A kind of tool quick changing device for the grass rake mechine that loosens the soil, described in loosen the soil
Grass rake mechine includes main part 2 and work head, it is characterised in that: tool quick changing device includes the work head being arranged on main part 2
Mounting seat 1 and the dop 6 being arranged on the first end of work, described work head mounting seat 1 is provided with draw-in groove 4 and block 5, described
Dop 6 can be connected in described draw-in groove 4, and by block 5 phase on the projection 7 on dop 6 and work head mounting seat 1
Work head is positioned by interaction in radial directions, prevents dop 6 from the most outwards coming off；On described dop 6 also
Being provided with stop pin, this stop pin is inserted into the lock hole 16 in work head mounting seat 1, thus by work head at axial direction
Upper locking.
Further, dop 6 being provided with stop pin through hole 15, stop pin is through described through hole, on dop 6 also
Being provided with spring 8, described spring 8 one end is against on dop 6, and the other end is against on the collar 13 being arranged on stop pin, lock
Rationed marketing produces bias force.
Further, described stop pin is provided with a rib block 9, dop 6 is provided with long strip type hole 14, when described
When rib block 9 is completely into long strip type hole 14, stop pin is locked in lock hole 16；When described rib block 9 is completely in long strip type hole
During 14 outside, stop pin disengages with lock hole 16.
It is provided with motor and actuating device in main body, is rotated by an output shaft drive work head.
The process of cutter is installed: first up carried by operation handle 11, extracted from long strip type by rib block 9, and rotate 90 degree,
Make rib be stuck in non-locked position soon, prevent stop pin under the effect of spring 8 from resetting；Work is laterally disposed, dop 6 and work
Make head mounting seat 1 to stagger certain distance, one end of work head is inserted in the output shaft on main body, dop 6 is blocked simultaneously
Enter in work head mounting seat 1, realize location radially by projection 7 and block 5.
After clamping puts in place, operation handle 11 turning to the position of locking, at this moment rib block 9 is not blocked, in spring 8 power
Effect under, stop pin reset, be locked in lock hole 16, thus realize axial lock.
The process of dismounting: operation handle 11 is up dragged, rib block 9 is extracted from long strip type hole 14, and rotate 90 degree and arrive
Unlocked position, at this moment rib block 9 is stuck on the face of dop 6, and stop pin can not reset；The most laterally drag work head, complete dismounting.
The Working head quick-changing mechanism simple in construction of the toolroom machine of the present invention, low cost, change cutter the easiest.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.The technical staff of the industry should
Understanding, above-described embodiment limits the present invention the most in any form, and the mode of all employing equivalents or equivalent transformation is obtained
Technical scheme, all falls within protection scope of the present invention.
