Take such scheme, have the following advantages:
As can be seen from the above scheme, because the thickness that all is connected with crossbeam and crossbeam above front and back two widthwise edges at substrate is thicker than substrate itself, therefore can guarantee under the prerequisite that understructure is firm wall thickness between the chute of attenuate substrate top and upper surface of base plate to greatest extent, even wall thickness is zero, that is the substrate of base is disjunct two narrow boards that are distributed in vertical protruding both sides, thereby the upper surface of base plate of general cutting machine and the distance of line slideway bottom surface have also been reduced to greatest extent to install, even when the common blades of use 105mm diameter and corresponding Small Universal cutting machine, depth of cut also can reach 21mm.
Because crossbeam is thicker, so can arrange therein the first clearance eliminating mechanism of eliminating chute and vertical protruding gap, first clearance eliminating mechanism specifically is set respectively under the twice crossbeam, described the first clearance eliminating mechanism is to arrange transverse groove on a side channel wall of described chute, and spring and slide block are arranged in described transverse groove from inside to outside successively; The first little translot is arranged on the one side of the described transverse groove notch of the vicinity of described slide block, arrange the second little translot on the opposite side cell wall of described chute, all be connected with up and down wheel shaft between cell wall in the described first and second little translots, all overlap roller is arranged on described wheel shaft, each roller all offsets with the two sides of described vertical projection.Thereby form a set of mechanism that is used for eliminating movement clearance by wheel shaft and the roller in the first little translot on spring, slide block, slide block, the second little translot on chute wall and two little translots, make the traveling priority precision of base very high.Even roller and line slideway wear and tear, also can not strengthen the cutting deviation of sheet material.And, owing to being rolling friction between roller and line slideway, when base moves along line slideway, resistance is very little.
When employing second or third space eliminating machine, the principle that eliminate in gap is still similar to the above, can be used for eliminating too the movement clearance of base and line slideway.
Because the spacing of twice crossbeam is enough large, can hold the base plate of the general cutting machine of different model.Because crossbeam is thicker, so can arrange on the twice crossbeam and compress screw, housing screw screws in and compresses screw, by a side pressure of pressing article in beam surface upper, the other end of pressing article is pressed on the base plate of general cutting machine, thereby conveniently fix securely general cutting machine, pressing article one end be pressed on base plate stretches into the base plate certain-length, to adapt to different general cutting machines.As can be seen here, with the exclusive guideway saw that needs to use cutter special in background technology, compare, not only reduced cost, and the general cutting machine of joining also can unload to do other purposes easily.
Because the upper surface of described substrate has two the first blocks near twice crossbeam place respectively in the one side, on described the first block and on the relevant position of described substrate, the first mounting hole and the first screw are arranged respectively, in this first mounting hole and the first screw, the first trip bolt is arranged, described the first trip bolt is through screwing in after described the first mounting hole in described the first screw; The length direction of described the first mounting hole is vertical vertical with line slideway; Under confined state, the inner end of described the first block offsets from the vertical side away from blade of side and described base plate.When the relative base of the good general cutting machine of accurate adjustment first after the cutting width direction is also perpendicular to the position on the traveling priority direction, by adjusting this two the first blocks, can be fixed up in this position, while again installing, as long as described base plate is come on the first block, can limit exactly the position of general cutting machine.While changing the outfit general cutting machine different, readjust the first stop location and get final product.In addition, the first block blocks base plate from the side, also can prevent under the vibration environment when cutting machine is worked, and slight the variation occurs in the cutting machine position, affects cutting accuracy.
