Below, conjunction with figs. is lifted a preferred embodiment, and in order to thin portion structure of the present utility model and effect are described, wherein used accompanying drawing brief description earlier is as follows, wherein:
Fig. 1 is the schematic diagram of the utility model one preferred embodiment, mainly shows the state that spiral arm does not rotate as yet;
Fig. 2 is the sectional perspective exploded view of the utility model one preferred embodiment;
Fig. 3 is the schematic diagram of the utility model one preferred embodiment, mainly shows the state that spiral arm is rotated down;
Fig. 4 is the schematic diagram of the utility model one preferred embodiment, mainly shows the state that spiral arm continues to be rotated down; And
Fig. 5 is the schematic diagram of the utility model one preferred embodiment, mainly shows the state of rotary transfer arm to lower dead center.
The specific embodiment
Seeing also Figure 1 and Figure 2, is the circular sawing machine that is provided for the utility model one preferred embodiment, and circular sawing machine includes a pedestal 11, a spiral arm 21, a saw blade 23, a protecting cover 31, and a connecting rod 41; Pedestal 11 has a sliding stand 12, sliding stand 12 has two sliding axles 17, each sliding axle 17 is sides that are arranged in pedestal 11, make the sliding stand 12 can be in pedestal 11 tops moving axially along sliding axle 17, sliding stand 12 is provided with the location division 14 that a support portion 13 and is positioned at 13 tops, support portion in addition, location division 14 is to can be cylinder or sleeve also or bearing, support portion 13 has one first section 15 and 1 second section 16, first section 15 is general linearlyly towards the extending laterally of sliding stand 12, and second section 16 then is predetermined angular ground from first section 15 outer end and extends towards the top.
This spiral arm 21 is hubbed at the sliding stand 12 of pedestal 11 by a rotating shaft 22, and sliding stand 12 is in order to driving spiral arm 21 along the moving axially of sliding axle 17, and spiral arm 21 is that the center of circle can be with respect to sliding stand 12 deflections with rotating shaft 22 in addition; This saw blade 23 is to be hubbed in the spiral arm 21, and the Lower Half of saw blade 23 exposes outside spiral arm 21, and saw blade 23 can be with respect to spiral arm 21 rotations by the drive of a motor (not shown).
This protecting cover 31 is to be the made cover body of transparent material, and protecting cover 31 is hubbed at spiral arm 21, and protecting cover 31 can be along the periphery deflection of spiral arm 21, and the Lower Half of saw blade 23 position of spiral arm 21 (that is expose outside) covers at protecting cover 31 inside.
This connecting rod 41 is to be microscler, and connecting rod 41 has a top 42 and a linearly guide groove 43, and top 42 is to can be cylinder or circular sleeve or bearing, and top 42 is positioned at the nearly middle position of connecting rod 41 and the surface of protruding connecting rod 41; Guide groove 43 extends axially along connecting rod 41, and an end of close connecting rod 41, and the other end of connecting rod 41 is the outsides that are hubbed at protecting cover 31 by another rotating shaft 44, and top 42 is butted on second section 16 top side of support portion 13, and 14 of location divisions are located in the guide groove 43.
Via said structure, as shown in Figure 3, when spiral arm 21 deflects down with respect to sliding stand 12, connecting rod 41 is also by drive and to bottom offset, make connecting rod 41 utilize top 42 and second section 16 position of replacing mutually of support portion 13 to be fulcrum, and then spur protecting cover 31, and move along linearly guide groove 43 location division 14 of sliding stand 12 with respect to spiral arm 21 rotations, protecting cover 31 can rotate comparatively apace, and makes saw blade 23 parts expose outside protecting cover 31; Because the guide groove 43 of connecting rod 41 is away from saw blade 23, guide groove 43 also is difficult for attaching greasy dirt or the smear metal that is produced in the sawing processing; As shown in Figure 4, when spiral arm 21 continues to deflect down, the top 42 of connecting rod 41 is resisted against second section 16 of support portion 13 constantly, and be skewed lateral wall along second section 16 and move, make connecting rod 41 continue pulling protecting cover 31, make protecting cover 31 bigger with respect to the angle of spiral arm 21 rotations, it is also more that saw blade 23 exposes outside the position of protecting cover 31; And as shown in Figure 5, when spiral arm 21 is driven to rotate to lower dead center, the top 42 of connecting rod 41 is second section 16 top side that move to first section 15 of 13 along the support portion, protecting cover 31 then can be rotated to predetermined angular by connecting rod 41 pullings, and the position that makes saw blade 23 expose outside protecting cover 31 is enough to carry out sawing processing.
Thus, the utility model can make protecting cover comparatively smooth and easy with apace with respect to spiral arm deflection, and can not be subjected to the greasy dirt that sawing processing produced or the influence of smear metal, reduce the puzzlement on using.
