Fig. 1 is the utility model one embodiment schematic diagram.
Wherein: 1 collet, 2 ring-type diamond saw blades, 31 active rollers, 32 return idlers, 41 guide rails, 42 slide blocks, 43 roller fixing devices, 5 pallets, 6 bases.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of diamond saw blade that the utility model provides realizes that polycrystal silicon ingot breaks square cutting equipment, the transmission mechanism that comprises collet 1, ring-type diamond saw blade 2,2 transmissions of drive ring-type diamond saw blade, drive the lowering or hoisting gear that transmission mechanism moves up and down, the sawtooth end of described ring-type diamond saw blade 2 is arranged on collet 1 top.Be provided with the roller fixing device 43 that is used for fixing transmission device on described lowering or hoisting gear, described collet 1 bottom is provided with the rotating mechanism that drives collet 1 rotation.
Above-mentioned cutting equipment adopts the diamond saw blade with one fixed width, and utilize transmission mechanism to drive, the direction of motion is single, the vestige that cutting process itself produces is less, and, along with the carrying out of cutting, due to the width of diamond saw blade, also can the less vestige produced be ground, polycrystal silicon ingot cut surface after making to have cut is smooth smooth, can omit the polishing process after cutting fully.
In an embodiment of the present utility model, also comprise pallet 5, described pallet 5 is packed on described collet 1 by the pallet fixed mechanism.Polycrystal silicon ingot is fixed in the pallet be consistent with the size of polycrystal silicon ingot, guarantees the stability of polycrystal silicon ingot in cutting process, can not be subjected to displacement and produce phenomenon such as cutting dislocation etc.
In another embodiment of the present utility model, described collet bottom is provided with the rotating mechanism that drives the collet rotation.Adopt rotating mechanism, after can realizing once cutting, do not need to take off polycrystal silicon ingot, directly collet is rotated, drive polycrystal silicon ingot rotation (can according to the split requirement different rotation angle) and, to suitable angle, cut for the second time.
In another embodiment of the present utility model, the utility model also is provided with the base 6 of settling described lowering or hoisting gear and/or collet 1.The purpose that base 6 is set is to make the operation that this equipment can be more stable, unlikelyly in running, shakes, and affects cut quality.
The schematic diagram that Fig. 1 is an embodiment of the present utility model, diamond saw blade as shown in Figure 1 realizes that polycrystal silicon ingot breaks square cutting equipment, settle lowering or hoisting gear on base 6, described lowering or hoisting gear comprises the elevating lever of four rectanglar arrangements, described elevating lever comprises guide rail 41 and slide block 42, described guide rail 41 bottoms are fixed on base 6, the fixed idler whell roller fixing device 43 of (comprising active roller 31 and return idler 32) is installed on described slide block 42, and described slide block 42 also is connected with controls the lifting drive (not shown) that slide block 42 rises and descends.Described transmission mechanism is two groups that are set up in parallel, an every group of active roller 31 and return idler 32 that transmission mechanism comprises, described two active rollers 31 and two return idlers 32 are packed on four slide blocks 42 by roller fixing device 43 respectively, described active roller 31 connection for transmission drive unit (not shown)s, diamond saw blade 2 is tightly on active roller 31 and return idler 32, form a driving-chain, the lower end of diamond saw blade 2 is the sawtooth end, over against the polycrystal silicon ingot be positioned on pallet 5, pallet 2 is fixed on collet 1 by pallet fixed mechanism (not shown), collet 1 bottom also is provided with the rotating mechanism (not shown) that drives the collet rotation.
Broken side's cutting equipment of above-mentioned employing diamond saw blade, utilization be that diamond saw blade is cut polycrystal silicon ingot.Because the diamond saw blade cutting power is strong, the high fly-cutting that can reach polycrystal silicon ingot of toughness.The quick rotation of diamond saw blade own, and along with slide block is moved from top to bottom on guide rail, reach the dissection to polycrystal silicon ingot, after having cut one time, saw blade lifts, polycrystal silicon ingot is with collet (having the rotating mechanism of collet bottom to drive) half-twist, then diamond saw blade cuts again, and after cutting finishes like this, polycrystal silicon ingot just is cut into standard-sized quadrangular silico briquette.
