Abstract
The invention relates to a horizontal type dual-V-shaped positioning seat of a silicon bar cutting machine. The horizontal type dual-V-shaped positioning seat comprises a bottom plate, an external V-shaped positioning seat, an internal V-shaped positioning seat, abrasion-resisting cushion blocks, regulating screws, nuts and fixed screws, wherein the regulating screws are symmetrically arranged on supporting surfaces of the external V-shaped positioning seat, the abrasion-resisting cushion blocks are symmetrically and fixedly arranged on two supporting surfaces of the internal V-shaped positioning seat, and the thickness of the abrasion-resisting cushion blocks is 12-15mm. Because the external V-shaped positioning seat is supported and positioned by two adjustable points, when a silicon bar is placed on the two V-shaped positioning seats, one end of the silicon bar is accurately positioned by the fixed internal V-shaped positioning seat, the other end of the silicon bar is supported and positioned by the two regulating screws, when the silicon bar has a defect of big head and small head, the cut end face is vertical to the horizontal surface through regulating the two regulating screws, and then the silicon bar is clamped and cut, therefore, the horizontal type dual-V-shaped positioning seat can ensure that the axis of the silicon bar is vertical to two end faces of the silicon bar in the structure, and ensure that the traditional clamp is more perfect.
Description
Technical field
The present invention relates to the anchor clamps of silicon rod segment cutter, relate in particular to the V-arrangement positioning seat part in a kind of silicon rod cutting machine special fixture of reversing end for end.
Background technology
In the manufacture of solar cells process, with silicon rod on request length to be cut into pieces be first procedure of silicon chip cutting processing, at present, the used anchor clamps of the silicon rod section of cutting are vertical pair of V-arrangement locating clip locking structures, two vee-block synchronous clamping mechanisms that it is distributed by three straight lines were carried out the location to silicon rod respectively and were clamped, every secondary vee-block clamp mechanism is come tense-lax by opposed two vee-blocks in front and back by the left and right sides screw rod mode of tightening up, in every secondary vee-block clamp mechanism, there are two anchor points to contact with silicon rod, its advantage shows: after the silicon rod location clamps, even the diameter of silicon rod, circularity, cylindricity has the axis height that error can not change the silicon rod two ends, the axis of silicon rod is parallel with horizontal plane, and the axis verticality of cutting two ends, back and silicon rod is good.But it is typically to cross location structure, but the system rigidity of this three secondary vertical pair of vee-block clamp mechanism is poor, if the cutting resistance is excessive, silicon rod can produce shake, makes cut surface produce difference of height, directly influences flatness; Vertical pair of V-arrangement locating clip locking structure, when cutting to end, anchor clamps must be unclamped, silicon rod can be cut after installing in tune on the anchor clamps, in this process, both needed a dead lift and tune, need again to reinstall and clamp, because silicon rod is not only sliding but also dirty, very easily landing injures the operator, and not only labour intensity is big, and complex operation, work efficiency is low, has potential safety hazard.
In order to overcome the deficiency that vertical pair of V-arrangement locating clip locking structure exists, Changzhou Tian Ze photovoltaic apparatus Manufacturing Co., Ltd discloses " the silicon rod cutting machine special fixture that can reverse end for end " in patent No. ZL201020256873.6, it is a kind of horizontal pair of vee-block locating clip locking structure, comprise two locating clip locking structures of forming by V-arrangement positioning seat and synchronous clamping mechanism that distribute along the silicon rod axially spaced-apart, whole positioning and clamping mechanism rotates around the center line of two V-arrangement positioning seats simultaneously, the synchronous clamping mechanism of this anchor clamps can clamp synchronously and unclamps silicon rod, silicon rod is placed on the horizontally disposed pair of V-arrangement positioning seat, movable clamping head is pressed in the top of silicon rod symmetrically, improved the system stiffness of whole anchor clamps, eliminated the silicon rod jitter phenomenon in the cutting process, the flatness of silicon rod cutting end face can guarantee.Owing to set up rotating mechanism between base and V-arrangement positioning seat, the V-arrangement positioning seat can rotate with respect to base, and it can satisfy silicon rod cutting machine technological requirement to the whole tune of clamp body in cutting process.Location locking mechanism can guarantee that the silicon rod revolution crosses just automatically location of 180 degree, lock by retaining mechanism then, it can satisfy the 180 degree tunes of needs in the silicon rod cutting process, the accurate technological requirement of location and fixing and locking well, both alleviate labor intensity of operating staff, improved production security and efficient again.Though this silicon rod cutting clamper has above-mentioned advantage, but also there is the not vertical defective of two cutting end faces and silicon rod axis in actual use, because the silicon rod cylindricity that draws out from crystal pulling furnace is not high, always there is the concentric reducer phenomenon in the silicon rod two ends, when silicon rod is shelved on horizontal two V-arrangement positioning seats, the axis of silicon rod and horizontal plane certainly exist certain angle, and the perpendicularity of cutting rear end face and silicon rod axis is bad, and this is to be reluctant the major defect that occurs in the silicon rod segment operation most.
Summary of the invention
The objective of the invention is the V-arrangement positioning seat among the ZL201020256873.6 is improved, provide a kind of silicon rod cutting machine horizontal pair of V-arrangement positioning seat, it can keep the silicon rod axis parallel with horizontal plane, can guarantee silicon rod cutting back both ends of the surface and silicon rod axis normal from structure.
The technical scheme that the present invention takes is:
Horizontal pair of V-arrangement positioning seat of a kind of silicon rod cutting machine, comprise base plate, outside V-arrangement positioning seat, inboard V-arrangement positioning seat, rotating hole, wear-resisting cushion block, adjustment screw, nut and hold-down screw, be distributed on the base plate to outside V-arrangement positioning seat and inboard V-arrangement positioning seat parallel interval, rotating hole is arranged on the center of base plate, it is characterized in that: on the left outer bearing surface of outside V-arrangement positioning seat and right outer bearing surface, be provided with adjustment screw and nut symmetrically, adjustment screw is screwed on left outer bearing surface and the right outer bearing surface, nut is screwed on the adjustment screw, on the left inner bearing face of inboard V-arrangement positioning seat and right inner bearing face, be fixed with wear-resisting cushion block symmetrically, wear-resisting cushion block is fixed on left inner bearing face and the right inner bearing face by hold-down screw, and the thickness of wear-resisting cushion block is 12～15 millimeters.
Because the positioning support to the two V-arrangement positioning seats in the ZL201020256873.6 patent improves, scheme by original fixed positioning support changes fixedly V-arrangement face location of an end into, the other end is adjustable two point locations, when silicon rod is shelved on two V-arrangement positioning seat, one end of silicon rod is by fixing V-arrangement face accurate positioning location, the other end is by two adjustment screw supporting location, when there is the concentric reducer defective in silicon rod, as long as when silicon rod is installed, be close to and cut end face with height gauge, by adjusting two adjustment screw, it is vertical with horizontal plane to guarantee to cut end face, and then clamping cutting, so just can guarantee that the silicon rod axis is parallel with horizontal plane, can overcome the silicon rod axis defective vertical that existing anchor clamps exist, make existing anchor clamps more perfect from structure with the silicon rod end face.
