Description

The special mis-cut angle positioner of cutting machine

The utility model relates to a kind of cutting machine, particularly a kind of special mis-cut angle positioner of cutting machine.

Shown in Fig. 1～3, general cutting machine 10 mainly is provided with a pin joint seat 12 at a workbench 11 rears, these pin joint seat 12 centre are concaved with an axis hole 121, can wear pivot for an axostylus axostyle 122 is screwed into, but make the solid transposase 11 3 of these axostylus axostyle 122 pivots on pin joint seat 12, this transposase 11 3 can be done arbitrarily angled rotation on pin joint seat 12, these transposase 11 3 tops are provided with an ear seat 131 can be for articulating a saw arm (figure does not show), axle is provided with saw blade in this saw arm, when saw arm is pressed down, saw blade can carry out sawing to the working substance of workbench 11, and this pin joint seat 12 is concaved with a screw 123 in a side edge, these transposase 11 3 one sides are provided with an adjustment hole 132 that is long arc shape relatively, one fixing button 14 penetrate adjust hole 132 and with screw 123 bolts, make this transposase 11 3 can turn a fixed angle on workbench 11, so saw blade has predetermined mis-cut angle to working substance, and general cutting machine 10 also provides the positioning function of special mis-cut angle, be installed with two blocks 15 in these pin joint seat 12 two bottom sides, these transposase 11 3 bottom sides convex with a positioning seat 133, these positioning seat 133 inner transverse have provided an axis hole 134, can insert a positioning rod 16 for axle and do slippage, these backstay 16 inner ends have one and support to end 161,161 the inners are provided with a lining papers 162 and axis hole 134 is made fit to ending for this, these backstay 16 outer ends are provided with a pull handle 163, these pull handle 163 surfaces have most grooves so that grip, and the middle stopper slot 164 that is concaved with predetermined length of these backstay 16 shafts, these positioning seat 133 spiral shell groups are gone into a limited screw 135 and can be extended in the stopper slot 164, use the shift position of limiting this backstay 16, when spurring this pull handle 163, the user can allow in ending 161 a retraction axis hole 134, this transposase 11 3 just can rotate freely on pin joint seat 12, use and fix this transposase 11 3 on any angular position, only support 161 and protrude out outside the axis hole 134 when pushing can allow during this pull handle 163, make this support end 161 and be subjected to two blocks, 15 retainings and support, use quick location transposase 11 3 on predetermined mis-cut angle position.

The device of cutting sth. askew of above-mentioned general cutting machine has the quick positioning function of special angle really, but, on the operation of member and the spendable angular range, still have following shortcoming: stopper slot 164 can only be accomplished the displacement location of two-period form in the middle of the backstay 16 of

general cutting machine

10,16 of 135 pairs of backstays of this limited screw provide block spacing and do not have a fixing function, for preventing this backstay 16 loose shift in axis hole 134, so sheathed lining papers 162 is to reach the close effect of ending on this backstay 16, but also therefore causing the user to be difficult for this backstay 16 of pulling moves, also can't experience and the distance that this backstay 16 moves and whether arrive the location, cause operational inconvenience, in addition, this two block 15 is rectangular block architecture just, and only provide the location of single special angle, when the user needed another kind of special angle commonly used, these two blocks, 15 structures can't provide.

The utility model purpose is to provide a kind of special mis-cut angle positioner that the relative saw blade of workpiece can be positioned multiple special mis-cut angle and cutting machine capable of rapid positioning.
