Abstract
The utility model relates to a worktable of a plane mill and end-surface mill dual-purpose butt barreling machine tool for a square monocrystalline silicon rod or a square polycrystalline silicon rod. The worktable comprises a butt barreling machine tool table; a workpiece bottom plate, a transverse positioning block and a vertical positioning block are arranged on the machine tool table; two compaction devices are respectively arranged at the left and right sides of the machine tool table; the workpiece bottom plate, the transverse positioning block and the vertical positioning block are vertical to one another and are fixed on the machine tool table; each compaction device is particularly an oil-pressure compaction device and comprises a pressing plate, a supporting column and an oil cylinder; and the pressing plate can ascend or descend under the action of the oil cylinder to press a workpiece. With the adoption of the worktable, the butt barreling machine tool can realize dual purposes of serving as a plane mill and an end-surface mill, so as to carry out plane milling and end-surface milling.
Description
Technical field
The utility model belongs to the crystal silicon solar batteries technical field, particularly relates to the flat stone mill and the dual-purpose butt barreling platen of end face mill of a kind of monocrystalline silicon or polysilicon square rod.
Background technology
After the operations such as monocrystal rod or polycrystal silicon ingot process evolution, cut-out, there are index defectives such as stria, four limit out of plumb, size two ends be inconsistent in the surface, when being directly used in section production, in cutting process, there are abnormal risks such as broken string, wire jumper, steel wire climbing, also there is bigger uncertainty in final silicon chip product aspect the uniformity of physical index, so require to increase flat stone mill end face mill treatment process in the square rod stage.And the processing of end face mill also is the utilization for the square rod splicing that cooperates up-to-date appearance.The length of silicon single crystal rod or polycrystal silicon ingot is because of the uncertain length of difference meeting output of production technology or inventory, slicer generally can be used for the square rod of processing criterion size, NTC442 type for example, it can process two square rods that are not more than 300mm length simultaneously.For short silicon rod, original splicing is one by one to be bonded in glass plate on less than the short silicon rod of 300mm two length overalls, stay the space of 3～5mm between two rods, it mainly is the not necessarily vertical and glass substrate of two end faces of considering every short silicon rod, such silicon rod that is spliced just is equivalent to have four end faces, if a certain end face and glass substrate out of plumb then increase the probability that steel wire is climbed greatly, there is very big broken string risk; And, when adopting up-to-date short silicon rod technique for sticking,, just two short bonding being integral of silicon rod can't be become the silicon rod of growing if there is the off plumb situation in end face.Existing butt barreling lathe is subjected to the restriction of workbench, only is applicable to flat stone mill, and can not carry out the end face mill.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, the flat stone mill and the dual-purpose butt barreling platen of end face mill of a kind of monocrystalline silicon or polysilicon square rod have been proposed, this workbench of butt barreling machine adopted, just can realize that flat stone mill and end face mill is dual-purpose, promptly flat stone mill can be carried out, the end face mill can be carried out again.
The technical scheme that the utility model technical solution problem is adopted is, a kind of crystal silicon rod flat stone mill and the dual-purpose butt barreling platen of end face mill, comprise butt barreling lathe bed platform, on described bed platform, be provided with workpiece base plate, located lateral piece and vertical locating piece, be provided with two hold down gags in the left and right sides of described bed platform; Vertical mutually and be fixed on the platform between described workpiece base plate, located lateral piece and vertical locating piece three.
As a kind of preferred, described hold down gag is an oil gag, comprises pressing plate, support column and oil cylinder, described pressing plate can be under the effect of oil cylinder rising or decline and pressure holding workpiece.
In the utility model, the workpiece base plate is a benchmark, the located lateral piece, vertical locating piece plays the effect of assist location, oil gag then plays chip hold down, it is to act on crystal silicon rod surface by the lever mode, pressure arm is that pressing plate is connected on the oil cylinder piston axle, and can be movable, there is the support column of regular length pressing plate one end below, workpiece then is positioned at the other end of pressing plate, and when hydraulic oil pump continued to extract hydraulic oil to oil cylinder, piston just remained on the oil cylinder extreme lower position always, thereby make a end that pressing plate pushes down workpiece to bottom offset, workpiece has been formed good pressure holding fixed effect.
Workpiece is carried out flat stone mill add man-hour, mainly rely on base plate and located lateral piece that workpiece is positioned, make it parallel, undertaken after machined parameters is provided with, just can finish the operation of flat stone mill by man-machine interface with the emery wheel face; Add man-hour carrying out end face mill, mainly rely on base plate and vertical locating piece that workpiece is positioned,, utilize its mutually perpendicular characteristic in four sides to make it vertical with the emery wheel face because the crystal silicon rod has been finished flat stone mill processing.Obtain the crystal silicon rod of standard cuboid profile after machining.
In the practical operation, when carrying out flat stone mill, workpiece laterally placed on the working plate and with a side abut against on the located lateral piece, with about two tightly pressure holdings of oil gag, import machined parameters by the man-machine interface of lathe then, after emery wheel is fed to Working position, open emery wheel, by moving from left to right of platen, surface of the work is processed, platen is return initial position after finishing, and carries out second processing behind the workpiece that manually overturns, and finishes plain grinding until the four sides.When carrying out end face when mill, workpiece is vertically placed on the working plate and with a side abut against on the vertical locating piece, with the tightly pressure holding of oil gag in left side, process then, after an end is finished, workpiece is changed a direction, again the other end is processed.
The utility model utilization, it is dual-purpose to make butt barreling lathe realize that flat stone mill and end face grind, and promptly can carry out flat stone mill processing, can carry out the processing of end face mill again, has saved equipment investment, has improved production efficiency.
Description of drawings
Fig. 1 is a kind of embodiment structural representation of the utility model.
The specific embodiment
Figure 1 shows that a kind of crystal silicon rod flat stone mill and the dual-purpose butt barreling platen of end face mill, comprise butt barreling lathe bed platform 1, on bed platform 1, be provided with workpiece base plate 2, located lateral piece 3 and vertical locating piece 4, be provided with two oil gags in the left and right sides of bed platform 1.Vertical mutually and be fixed on the platform 1 between workpiece base plate 2, located lateral piece 3 and vertical locating piece 4 threes with screw.Oil gag comprises pressing plate 5, support column 6 and oil cylinder 7, pressing plate 5 is connected on the axis of the piston of oil cylinder 7, and under the effect of hydraulic oil pump, pressing plate 5 can rise or descend, because the existence of support column 6, pressing plate 5 push down workpiece one end then to bottom offset and tightly pressure holding workpiece.
