Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further.
A preferred embodiment of the multifunctional saw of the utility model saw blade able to quickly change as Figure 1-3, it comprises by the main shaft 01(of transverse direction see Fig. 3) the vertical output shaft 02(that drives is see Fig. 1-2), output shaft 02 is assemblied in a head capsule 03, described head capsule 03 is a part for the complete shell forming whole product, the another part forming the complete shell of whole product is housing, because housing is not directly withdrawn deposit substantive distinguishing features of the present utility model, therefore housing does not show in the example shown; Feature of the present utility model is: output shaft 02 is provided with the first cramping body 04, head capsule 03 is equipped with elevating mechanism 05 and turning handle 06, second cramping body 07 being connected to elevating mechanism upper end, lower end, adjacent first cramping body 04 of second cramping body 07, rotate turning handle 06 to order about elevating mechanism 05 and clamp saw blade 08 with the second cramping body 07 near the first cramping body 04 or unclamp saw blade 08 away from the first cramping body 04, therefore simple to operate, convenient and swift when installing or change saw blade.
In order to the rotation of turning handle 06 being converted to the lifting of elevating mechanism 05, turning handle 06 is coordinated with elevating mechanism 05 by helicitic texture.
Concrete, elevating mechanism 05 comprises lifting sliding sleeve 51 and pull bar 52, lifting sliding sleeve 51, second cramping body 07 is connected to upper end, the lower end of pull bar 52, lifting sliding sleeve 51 is coordinated with turning handle 06 by helicitic texture, therefore, when rotating turning handle, order about the lifting of lifting sliding sleeve by helicitic texture, and then with pull bar, the second cramping body lifting.
Turning handle 06 is rotating to be assembled with head capsule 03 and is pressed on head capsule 03 by a gland 31, and make turning handle 06 only can rotate relative to head's shell and can not be elevated relative to head capsule, what lifting sliding sleeve 51 can move axially be assemblied on head capsule 03.Guarantee the lifting rotation of turning handle being converted to lifting sliding sleeve.
Pull bar 52 is located on head capsule 03, can avoid lifting sliding sleeve, the second cramping body rotation.
Lifting sliding sleeve, the second cramping body can be fixedly connected with (as passed through locknut) respectively in the upper end of pull bar, lower end, the lifting that rotation by means of only turning handle is converted to elevating mechanism impels the second cramping body near the first cramping body clamping saw blade or unclamps saw blade away from the first cramping body, therefore, second cramping body both can be positioned at the upside of the first cramping body, also can be positioned at the downside of the first cramping body.On this basis, portion repels effect on the second cramping body fastening spring, makes the elastic force of fastening spring impel the second cramping body near the first cramping body.
The upper end of pull bar 52, lower end also can be located in lifting sliding sleeve 51 respectively, second cramping body 07 makes be elevated sliding sleeve, second cramping body is movable relative to pull bar, based on this structure, second cramping body 07 is difficult to produce the blessing power being close to the first cramping body in a direction, therefore, can act on the second cramping body 07 and have fastening spring 71, the elastic force of fastening spring 71 impels the second cramping body 07 near the first cramping body 04, as shown in the figure, second cramping body 07 is positioned at the upside of the first cramping body 04, during concrete enforcement, second cramping body 07 also can be positioned at the downside of the first cramping body 04, fastening spring now can change and become extension spring.
And during position relationship between change second cramping body and the first cramping body, as required, the rotation direction changing described helicitic texture can mate the relation turned between the lifting of elevating mechanism of turning handle.
As shown in the figure, in order to make compact conformation, output shaft 02 is assemblied in head capsule 03 by bearing 32,35, head capsule 03 connects a bearing cap 33, the inner side of bearing cap 33 is provided with a cushion block 34, and fastening spring 71 is helical pressure and its two ends are supported on the second cramping body 07 and cushion block 34 respectively.For avoiding output shaft 02 axially to descend play along it, output shaft being made Step Shaft and relies on shaft block ring 24, bearing cap 33 to be positioned at by bearing head capsule realizes the axial location to output shaft.
For the ease of changing and reliable retention saw blade, saw blade 08 has one can be enclosed within gap slot 81 on output shaft, second cramping body or the first cramping body 04 and saw blade 08 set up locating hole 82 and locating dowel 41 separately, therefore when the second cramping body 07 leaves the first cramping body 04, from the side direction of output shaft 02, gap slot 81 can be inserted facing to output shaft 02 by hand-held saw blade 08, and make locating dowel 41 insert in locating hole 82, rotate turning handle 06 afterwards and make the second cramping body 07 clamp saw blade 08 near the first cramping body 04.Saw blade can not be clamped in order to avoid producing gap between the second cramping body and the first cramping body, groove can be set on the second cramping body of corresponding locating dowel or the first cramping body and avoid locating dowel to interfere for holding longer locating dowel.
For making saw blade wobbling action, output shaft 02 is fixed with fork 21, fork 21 has draw-in groove 22, and the front end of main shaft 01 is made eccentric shaft 11 and is engaged in draw-in groove 22, therefore when the shaft rotates, namely orders about main shaft by eccentric shaft and swings with saw blade.In order to reduce wear, on eccentric shaft, cover has bearing 16 and is located by shaft block ring 18.But this structure does not repel the continuous rotation of output shaft, as rotation can be passed to output shaft by bevel gear mechanism by main shaft continuously.
In order to avoid the imbalance that eccentric shaft 11 causes when rotating, the front end of main shaft 01 is equipped with balance weight 12.
Turning handle 06 and head capsule 03 are provided with location structure 61, during for turning handle being turned to the position clamping saw blade or the position of unclamping saw blade, turning handle are positioned at head capsule.Concrete, as shown in the figure, turning handle is equipped with elasticity locating convex block by securing member and structural member, head capsule is offered corresponding locating slot.
Main shaft 01 is assemblied in housing, head capsule 03 is assemblied in the front end of housing by securing member, concrete, together with diagram main shaft is made as by bearing 14,15 support rotating and with rotor 13, and be one of them Bearing configuration bearing block 17, vibration passing during in order to reduce work, bearing block 17 is provided with shock absorbing ring 19, and when bearing block 17 is arranged on head capsule 03, shock absorbing ring 19 is between bearing block 17 and head capsule 03.As previously mentioned, head capsule, housing form the complete shell of whole product together, hold with a hand during for using, but housing itself is also be made up of many parts usually.
The lower end of output shaft 02 is connected with saw blade pressing plate 23 by securing member, for other fastening saw blade.
