Description
Technical field
The present invention relates generally to a kind of mitre saw, particularly the guardrail of mitre saw.
Background technology
Known common mitre saw generally has a base assembly 12 (comprising a rotary table assembly 13), one saw componet 14 (comprising a blade 14B), be arranged on pivotly on the table assembly 13, make user's saw componet 13 that pivots downwards, 14B moves to table assembly with blade, as shown in Figure 1.Table assembly 13 can be around vertical axis rotation to carry out the angle cutting.
Because mitre saw is generally used for cutting the convex surface mould, an oblique angle mechanism 35 preferably is provided, saw componet 14 can be pivoted, to change the angle of blade 14B with respect to table assembly 13, i.e. inclination angle around a trunnion axis.Therefore, selecting the angle angle, rotating saw assembly 14 to be selecting the inclination angle by rotary table assembly 13 for the convex surface mould M shown in Fig. 1, thereby the saw componet 14 that pivots downwards then cuts to cut the mould that this mould M is positioned at this on table assembly 13 and cuts.But 35 designs of oblique angle mechanism and manufacturing are all expensive.It may increase the inaccuracy of saw 100, produces the inaccuracy cutting, causes material, the loss of time and/or money.
Have oblique angle mechanism 35 and need a different guardrail.Guardrail is fixedly installed on the base assembly 12, with supporting workpiece when cutting.In the mitre saw that does not have oblique angle mechanism, guardrail is generally rectangle.In the mitre saw that oblique angle mechanism is arranged, promptly make up in the mitre saw, guardrail can have big gap near blade, to form the gap at any inclination angle.But, because big gap arranged, this guardrail can not be at different inclinations angle supporting workpiece rightly, cause inaccurate or rough lumber is cut.
U.S. Patent No. 5,297 proposes a kind of fence assembly 20 in 463, and it has a slip guardrail part 24, with at all angle supporting workpieces.But this guardrail cost is very expensive.
The art methods of another cutting convex surface mould is presented among Fig. 2, and wherein identical label is represented similar parts.Mould M places between guardrail 20 and the table assembly 13 with an angle.One stop part 25 can be used for keeping mould M.By changing the inclination angle, mould M can be cut along a synthetic angle, and does not need the inclination angle adjustment.But because the bottom of mould M is not supported on the guardrail basically, it may splitting, causes the inaccuracy cutting, and this can cause material, the loss of time and/or money.
Summary of the invention
The invention provides a kind of improved saw.This saw comprises: a base; One is installed in rotation on the workbench on the base; One is installed in the saw componet on the workbench; One is installed in first fence assembly on the base, first fence assembly comprises a workpiece support surface, at least one surperficial primary importance that can be in being approximately perpendicular to workbench surface and susceptor surface and with respect to moving between the second place of at least one surface tilt in workbench surface and the susceptor surface.
Another saw comprises: a base; One is installed in rotation on the workbench on the base; One is installed in the saw componet on the workbench; One is installed in first fence assembly on the base, it comprises one first workpiece support surface, be approximately perpendicular at least one surface and one second workpiece support surface in workbench surface and the susceptor surface, it is at least one surface tilt in the surperficial and susceptor surface with respect to workbench.
