Detailed description of the invention
More fully example embodiment is described referring now to accompanying drawing.But example embodiment can be implemented in a variety of forms, and should not be understood to be limited to embodiment set forth herein; On the contrary, these embodiments are provided to make the utility model comprehensively with complete, and the design of example embodiment will be conveyed to those skilled in the art all sidedly.Reference numeral identical in figure represents same or similar structure, thus will omit their detailed description.
Embodiment one
As shown in Figures 1 and 2, present embodiment discloses a kind of line cutting machine guide wheel, comprise wheel shaft 1, wheel body 2 and outer ring 3.Wheel shaft 1 is fixed in the frame of line cutting machine, and wheel body 2 rotates and is arranged on wheel shaft 1, and outer ring 3 fixed cover is located in the outer rim of wheel body 2.In the present embodiment, wheel shaft 1 is provided with two bearings 4, and this wheel body 2 is rotatably supported on wheel shaft 1 by bearing 4, but in the utility model, the mode be rotationally connected between wheel shaft 1 and wheel body 2 is not limit.
Wheel body 2 comprises columniform first support portion 21 of coaxial line setting and the second support portion 22 of a disc-shaped, and that is, the thickness of the second support portion 22 is less than the thickness of the first support portion 21.In the middle part of the first support portion 21, be provided with a through centre bore, this centre bore is used for coordinating with the outer ring of bearing 4.After bearing 4 is loaded centre bore, respectively connect an end cap 5 at the two ends of the first support portion 21 with screw 6 and position for bearing 4, thus, the first support portion 21 and wheel shaft 1 can be made to be formed and be rotationally connected.The diameter of the second support portion 22 is greater than the diameter of the first support portion 21, and outer ring 3 is then set in the outer rim of this second support portion 22.Because the second support portion 22 has larger diameter, thus the internal diameter of outer ring 3 correspondingly can be expanded when the external diameter of outer ring 3 is constant, make the lower thickness of outer ring 3, the material of outer ring 3 can be reduced like this, and due to the thickness of the second support portion 22 relatively thin, also more easily install outer ring 3.Certainly, in other embodiments of the present utility model, also can omit the second support portion 22, outer ring 3 is directly set in the outer rim of the first support portion 21.
See Fig. 3, ringwise, be provided with the wire casing 31 of annular at the periphery wall of outer ring 3, this wire casing 31 can coordinate with the chopping of line cutting machine, supports and guide chopping to carry out cutting silicon wafer to chopping in outer ring 3.In the present embodiment, the V-groove of wire casing 31 to be cross sections be V-type, can position chopping like this, the cross section of wire casing 31 also can be other shapes, as half-arc groove etc.Wheel body 2 can adopt aluminum alloy material, lighter in weight and have good rigidity, and outer ring 3 then can utilize metal material or nonmetallic materials manufacture.When outer ring 3 utilizes metal material to manufacture, the securing members such as screw can be utilized to be fixed on wheel body 2.In the present embodiment, outer ring 3 is resin outer ring, can pass through the mode such as injection moulding or machined batch micro operations.This outer ring 3 is demountable relative to wheel body 2, in the present embodiment, the outer rim of the second support portion 22 is light face, and the inner surface of outer ring 3 is similarly light face, outer ring 3 is enclosed within the outer rim of the second support portion 22, and outer ring 3 and the second support portion 22 glued joint to get up by blend compounds water.
Because outer ring 3 is wearing detail, when line cutting machine works, chopping meeting is wearing and tearing outer ring 3 constantly, if change outer ring 3, this line cutting machine guide wheel is only needed to take off, extractd and the outer ring more renewed from wheel body 2 outer ring 3, the annexes such as wheel shaft 1, wheel body 2 and bearing 4 can reuse, therefore without the need to this line cutting machine guide wheel is changed completely.The cost of outer ring 3 is relatively cheap, thus can reduce the maintenance cost of line cutting machine.
Embodiment two
See Fig. 4 to Fig. 6, present embodiment discloses a kind of line cutting machine guide wheel, the difference of it and embodiment one is, is provided with annular slot 221 in the outer rim of wheel body 2, the inner side of outer ring 3 is provided with the annular boss 32 coordinated with annular slot 221, and this annular boss 32 is sticked in annular slot 221.Particularly, the outer rim of the second support portion 22 of wheel body 2 is provided with annular slot 221, and its first support portion 21 is identical with embodiment one structure.
By the cooperation of annular slot 221 and annular boss 32, can reliably outer ring 3 be fixed on wheel body 2, when dismantling outer ring 3, annular boss 32 is only needed to shift out annular slot 221, being separated of outer ring 3 and wheel body 2 can be realized, so just without the need to line cutting machine guide wheel is taken off from line cutting machine completely, outer ring 3 can be changed in position, further increasing convenience.
Below illustrative embodiments of the present utility model is illustrate and described particularly.Should be appreciated that, the utility model is not limited to disclosed embodiment, and on the contrary, the utility model intention contains and is included in various amendment in the spirit and scope of claims and equivalent arrangements.
