The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 3, be the stereo appearance figure and the three-dimensional exploded view of circular sawing machine workbench of the present invention.The present invention includes a platform 10 and two and extended platform 20, this platform 10 and two extends platform 20 and is installed on the support 90, and two extend the both sides that platform 20 is located at this platform 10, this platform 10 and two extension platforms, 20 formation flat surfaces.The material of this platform 10 is a metal, and two materials of extending platform 20 are granite.Also be provided with one division dish 30 on this platform 10 and this extension platform 20, this index dial 30 has angle adjustment and slippage function, to carry out the workpiece location.
With reference to Fig. 4 to Fig. 6, be the generalized section and the thin portion enlarged drawing of circular sawing machine workbench of the present invention simultaneously.This platform 10 has an end face 11 and two sides 12, the end face 11 of this platform 10 is a working face, the both sides of this end face 11 are concaved with an axial conduit 13 respectively, this conduit 13 is in the corner that this end face 11 and this side 12 form, and this end face 11 is between two conduits 13, this conduit 13 forms a retaining edge 131 away from an end of this side 12, slides for index dial 30 and prevents its disengaging when establishing.So conduit 13 is formed on the side of this platform 10, in processing, can directly carry out Precision Machining by side, the end face 11 that makes this platform 10 is between two conduits 13, so processing conduit 13 can not have influence on the flatness of the end face 11 of platform 10, and easy to processly more can effectively reduce cost.
The end face 11 of this platform 10 also is provided with a tool rest 14, is provided with for the annular saw (not shown).
The back side of this platform 10 is provided with four corners that four engagement grooves, 15, four engagement grooves 15 are positioned at this platform 10, and pass this support 90 with a fixture 16 respectively and screw lock at this engagement groove 15, and this fixture 16 can be adjusted the flatness of this platform 10.
Two extend platform 20 meets 12 places, two sides that are located at this platform 10 respectively, in order to enlarge working face.This extension platform 20 has an end face 21 and a side 22, and this end face 21 is a working face, and the 22 corresponding sides 12 that are located at this platform 10, side of this extension platform 20 are extended the end face 21 of platform 20 and the end face 11 of this platform 10 simultaneously and are same plane.
With reference to Fig. 7 and Fig. 3 A, the side 22 of this extension platform 20 is located at the side 12 of this platform 10 simultaneously, and this side 22 of extending platform 20 forms block face with respect to this conduit 13, makes this conduit 13 for index dial 30 sliding establishing.This index dial 30 is provided with a slide block 31, and this slide block 31 is slidingly installed in this conduit 13, and these slide block 31 1 ends are provided with an eccentric wheel 32, and this eccentric wheel 32 is limited to this retaining edge 131 and breaks away to prevent index dial 30.This eccentric wheel 32 has a breach 321, this slide block 31 is provided with a limited post 311, to limit the scope that this eccentric wheel 32 rotates, these eccentric wheel 32 selectivity protrude from a wherein side of this slide block 31, can be applicable to the conduit 13 of platform 10 both sides for this index dial 30.
This extension platform 20 is provided with two first engagement grooves 23 and two second engagement grooves 24, two first engagement grooves 23 are positioned at the centre of this extension platform 20, and pass this first engagement groove 23 and be combined in this support 90 with one first fixing group 25 respectively, two second engagement grooves, 24 contiguous these extend the side 22 of platform 20, and pass this second engagement groove 24 and be combined in this support 90 with one second fixing group 26 respectively.
It is rectangular tabular that this extends platform 20, and make for granite, and granite is the firmest a kind of in the rock, and not only quality is hard even for it, and is not subject to the erosion of soda acid.In the time of decades, significantly influence can not take place to it in slacking, so precision is quite high.On its every sq, can resist to such an extent that live pressure more than 2000 kilograms.In the mineral grain of forming granite, more than 90% feldspar, quartzy these two kinds of mineral, feldspar and quartz all are hard mineral, with the also difficult paddling of steel knife.
The character that granite has: yielding, the life-span is long, wearability is not 8 times on a metal; The hardness height is about 2.5 times on metal; Be subjected to temperature, humidity effect little, and internal stress free; Anti-corrosion property is strong, and is nonmagnetic, do not produce tackness; Non-corrosive, easy to clean, maintenance.If be impacted, its surface particles formation pit that comes off, but projection not around the pit, so do not influence flatness, its shock resistance is good.The physical property of granite and mechanicalness: proportion:＞2.8g/cm; Moisture content:＜0.05%; Hardness: Mohs' hardness is in the 5-7 level.
Two extend the two sides 12 that platforms 20 are located at this platform 10, are the characteristic of granite material by extending platform 20, and can protect material is that the platform 10 of metal is difficult for being collided and produces projection.This rectangular area of end face 21 that extends platform 20 is greater than the rectangular area of the end face 11 of this platform 10, makes that end face 11 areas of this platform 10 are little and keeps the flatness of end face 11 easily.
This conduit 13 is located at the side of this platform 10, in processing, can directly carry out Precision Machining by side, the end face 11 that makes this platform 10 is between two conduits 13, so processing conduit 13 can not have influence on the flatness of the end face 11 of platform 10, and easy to processly more can effectively reduce cost.
