The technical solution of the utility model is achieved in that
The utility model provides a kind of fraising instrument for fork truck back axle, comprises reamer, has the main body of column, and the first end of main body is provided with the cutter tooth that the length direction along main body extends; Connecting portion, the first end of connecting portion is connected with the second end of reamer, and the second end of connecting portion is connected with the rotating shaft of lathe; Transmission device, is arranged between reamer and connecting portion, and when reamer and connecting portion in the vertical direction are non-alignment state, the force that connecting portion can be subject to by transmission device is vertically delivered on reamer.
Further, transmission device comprises support body and two connectors, and the two ends of support body are connected to a connector, are all connected by universal joint between support body and connector.
Further, connector is provided with screwed hole away from one end of support body, and reamer and connecting portion are provided with the external screw thread with screwed hole adaptation.
Further, connecting portion is taper shank shape.
Further, the first end of reamer is arranged with stop collar, and stop collar is positioned at the top of cutter tooth.
Further, cutter tooth is many, and much knives tooth is distributed in the first end of main body along the circumferencial direction of main body.
Fraising instrument for fork truck back axle of the present utility model connects reamer and connecting portion by transmission device, while the rotating shaft band rotation connection of lathe carries out rotating, the power that connecting portion is subject to by transmission device to be vertically delivered on reamer and to drive reamer to rotate, reamer is made to carry out fraising to upper lower opening, and without the need in the vertical direction alignment reamer and connecting portion in transmittance process.Reamer in use, only need being vertically located in upper lower opening, without the need to adjusting alignment fully to lathe rotating shaft, reamer and upper lower opening, drastically increasing precision and the operating efficiency of fraising by fraising instrument of the present utility model.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of a kind of fraising instrument for fork truck back axle of the present utility model.
In figure:
10, reamer; 20, connecting portion; 31, support body; 32, connector; 33, universal joint.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with see accompanying drawing 1, as can be seen from the figure, the fraising instrument of the present embodiment comprises reamer 10, connecting portion 20 and transmission device.Wherein, reamer 10 has the body of column, and the first end of body is provided with the cutter tooth that the length direction along main body extends.The first end of connecting portion 20 is connected to the second end of reamer 10 by transmission device, the second end of connecting portion 20 is connected with the rotating shaft on lathe.The power that connecting portion 20 is subject to vertically can be delivered on reamer 10 when vertical direction does not align at reamer 10 and connecting portion 20 by the transmission device be arranged between reamer 10 and connecting portion 20.The fraising instrument of the present embodiment connects reamer 10 and connecting portion 20 by transmission device, while the rotating shaft band rotation connection 20 of lathe carries out rotating, the power that connecting portion 20 is subject to by transmission device to be vertically delivered on reamer 10 and to drive reamer 10 to rotate, make reamer 10 carry out fraising to upper lower opening, and can when reamer 10 and connecting portion 20 at vertically non-alignment carry out.Reamer 10 in use, only need vertically be located in upper lower opening, without the need to carrying out the adjustment of position to lathe rotating shaft, reamer 10 and upper lower opening, drastically increase operating efficiency by the fraising instrument of the present embodiment.
Preferably, transmission device comprises support body 31 and two connectors 32, and the two ends of support body 31 are connected to a connector 32, and are all connected by universal joint 33 between two connectors 32 and support body 31.The use of two universal joints 33 transmission device is had larger freedom, capable transmission between support body 31 and connector 32 can be carried out along non-vertical direction, namely fraising instrument in use, do not have specific shape between support body 31 and connector 32, enhances the flexibility of fraising instrument.
In the present embodiment, the connection between connector 32 and reamer 10 or connecting portion 20 is undertaken connecting by the mode of screw thread.One end away from universal joint 33 of connector 32 is provided with screwed hole, and the second end of reamer 10 and the first end of connecting portion 20 are provided with the external screw thread suitable with screwed hole.Preferably, the second end of reamer 10 is provided with the column that diameter is less than main body and protrudes, and external screw thread is arranged on column and protrudes.Correspondingly, the first end of connecting portion 20 is provided with identical protruding with externally threaded column.
For improving fraising efficiency, the first end place of main body is provided with much knives tooth, and much knives tooth is along the circumferential direction arranged on the first end of main body, and each cutter tooth all extends along the length direction of main body.The cutter tooth of such setting, can carry out fraising to upper lower opening simultaneously, and the fraising precision of lower opening can be made consistent.Also be provided with stop collar at the first end of main body, this stop collar is arranged on the top of cutter tooth and the external diameter of stop collar is greater than the diameter treating fraising.Stop collar the relative position that can limit main body and treat between fraising is set, guarantee that whole hole walls that cutter tooth can treat fraising carry out fraising.Preferably, connecting portion 20 is in taper shank shape.
