Abstract
The utility model provides a fixing structure of tool on grinding head for internal microtome, comprising a cutter holding disk which is fixedly fixed with a grinding head for microtome and is provided with a positioning pin, and an upper ring which is matched with the cutter holding disk and is provided with an inward ring to clamp and fix a cutter, wherein, the upper ring is additionally provided with a ring convex rib on the working face for clamping the cutter further and the cutter holding disk is correspondingly provided with a complementary ring groove. The tool composed in the way can prevent the cutter from internally moving to decrease pretightening force needed by a screw and enables a home-made slicer to cut large size (2.5-3' crystal plates with improved slicing qualities.
Description
The utility model relates to the inside diameter slicer that is used to cut crystalline materials such as germanium silicon single crystal, the particularly Transform Type design of slicing machine grinding head tool fixed structure.
At present domestic and international used single-crystal wafer machine, its bistrique fix a cutting tool fixed structure include the ring and the dress cutterhead, the dress cutterhead is provided with screw and alignment pin, on encircle and be provided with internal projecting ring, screw passes the through hole at circular shear blade edge, tool-holder fastened simultaneously with screw jacking internal projecting ring the dress cutterhead and between the ring.The shortcoming of this kind fixed structure is the tension force inequality, and the screw insufficient pressure is moved in cutter hub is easy, and home-made machine J-50 type can not be cut the wafer of large scale as 2.5 " 3 ", and the anxiety that easily wafer is smashed is arranged.
The utility model aims to provide a kind of novel slicing machine grinding head tool fixed structure, and it can be fixed cutter better, the single-crystal wafer quality is improved, and solved the problem that national J-50 type machine can not be cut large-sized wafer.
This purpose realizes as follows: a kind of inside diameter slicer grinding head tool fixed structure, it includes one and is connected with the slicing machine bistrique and the dress cutterhead and that has an alignment pin cooperates, has internal projecting ring with the dress cutterhead and last ring that tool-holder is fastened.The wherein said ring that goes up has additional an annular convex rib for further clamp-on tool, the corresponding complementary shape annular groove that is provided with of described dress cutterhead on its stationary face.
Below in conjunction with accompanying drawing the utility model embodiment is described, therefrom can be more clearly visible architectural feature of the present utility model and advantage.In the accompanying drawing:
Fig. 1 is the bistrique front view that cutter is housed;
Fig. 2 is the cut-away view of bistrique along A-A, B-B, C-C, D-D line.
As shown in Figure 1, 2, the bistrique fixed structure includes ring 2, following loop section 3, dress cutterhead 4, and the disc-shaped cutting tool clamping is between last ring, following loop section, and the circular void in the blade 11 is waited until and inserted the wafer cutting.In the prior art, following loop section 3 and dress cutterhead 4 are one.The utility model is divided into two parts with it.So during the tool changing tool can with go up ring 2, the toolbox that constituted in 1 minute of ring portion 3, cutter change separately and unlikely after shutting down for a long time down.
Be equipped with some screws 21,31,41 on last ring 2, following loop section 3, dress cutterhead 4 peripheries, also be provided with internal projecting ring 22 on the working face of last ring 2, it clamps cutter 1 wherein with the groove 32 of following loop section 3 by some screws (analysing and observe as D-D, C-C), and D-D cuts open alignment pin 33 among the figure and A-A and cuts open centring ring 35 among the figure initial alignment between all being used for encircling up and down.More than be improvement design of the present utility model is described in detail in detail below the prior art structure: further clamp for making cutter 1, prevent to move in the cutter hub and reduce the pressure of fixed screw, the inventor proposes to increase the scheme of a convex tendon 24 on last ring 2 working faces, it cooperates with the complementary shape groove 34 of following loop section 3, and (annular groove 34 shapes have discrepancy slightly among the figure, be for preventing foozle, only needing milling a little to constitute respective shapes during installation gets final product), thus on working face, further cooperate clamp-on tool 1 with internal projecting ring 22.In view of dress cutterhead part 4 was arranged with following loop section in 3 minutes, same screw 41 and the alignment pin 42 of adopting that be connected between the two cooperates fixing.On the screw 41 centring ring 42 is set also in addition.
In the present embodiment, convex tendon 24 is arranged on the circumference position of screw 21 so that utilize screw pressure clamp-on tool 1 better.
Claims (4)
1, inside diameter slicer grinding head tool fixed structure, comprise that one cooperates, has internal projecting ring with dress cutterhead and that the slicing machine bistrique was connected, had alignment pin with the dress cutterhead and last ring that tool-holder is fastened, it is characterized in that: the described ring that goes up has additional an annular convex rib for further clamp-on tool, the corresponding complementary shape annular groove that is provided with of described dress cutterhead on its stationary face.
2, cutter structure as claimed in claim 1 is characterized in that the described convex tendon of going up ring is arranged on the circumference position of fixing threaded hole of ring.
3, cutter fixed structure as claimed in claim 1 or 2 is characterized in that described dress cutterhead can be divided into dress cutterhead part that bistrique is connected and cooperates and the following loop section of fixed cutting tool with last ring 1, and last ring and following loop section constitute a cutter fixation kit; Described dress cutterhead part and following loop section carry out detached type by screw and alignment pin to be fixed.
4, cutter fixed structure as claimed in claim 3 is characterized in that the fixing threaded hole of described dress cutterhead part is provided with centring ring.
