Abstract
The utility model discloses a tooth portion processing frock for eccentric shaft, but including suit in the positioning disk by outside the processing eccentric shaft, the positioning disk is equipped with and is processed eccentric shaft complex locating hole along the axial, the positioning disk lateral wall is equipped with the alignment face, and this frock can be the processing of alignment point processing becoming alignment face, its great reduction the alignment degree of difficulty before the eccentric shaft processing spline tooth, require also to reduce to operator's technical ability by a wide margin.
Description
Technical field
The utility model relates to excentric shaft processing units field, in particular to a kind of teeth portion processing tool for excentric shaft.
Background technology
The excentric shaft in an axle section with spline tooth is on RV wheel casing a structural part, usually need between spline tooth and excentric shaft to ensure a special position relation, the tooth top of such as spline tooth needs to align with the minimum height of excentric shaft, to the method for part for look for positive eccentric high point with lever meter in prior art, then process spline tooth, and this high point is a point in theory, look for positive difficulty big, the technical ability of operator is required also higher, the part scrap rate height processed, and working (machining) efficiency is low.
Therefore, need one can turn into looking for front to process looking for processing on schedule, its greatly reduce excentric shaft processing spline tooth before look for positive difficulty, the technical ability of operator is required also much slower, the part processed is substantially without the teeth portion processing tool for excentric shaft of waste product.
Practical novel content
In view of this, the purpose of this utility model is to provide one and processing on schedule will be looked for turn into looking for front to process, greatly reduce excentric shaft processing spline tooth before look for positive difficulty, the technical ability of operator is required also much slower, and the part processed is substantially without the teeth portion processing tool for excentric shaft of waste product.
Teeth portion processing tool for excentric shaft of the present utility model, comprises the dowel disc can being set in outside processed excentric shaft, the pilot hole that described dowel disc is provided with vertically with processed excentric shaft coordinates; Described dowel disc outer side wall is provided with looks for front;
Further, described inclined pilot hole comprises centre hole and eccentric hole; The described eccentric axial line in hole and the axis parallel of centre hole;
Further, look for front vertical in the eccentric hole heart line in hole and the hole determined plane of heart line of centre hole described in;
Further, the outer side wall of described dowel disc is circumferentially distributed with multiple points of teeth groove;
Further, the screw that described dowel disc is disposed radially with eccentric hole is connected.
The beneficial effects of the utility model: the teeth portion processing tool for excentric shaft of the present utility model, pilot hole is hole at least two, in one of them, there is bias in hole, its size and eccentric amount need to be determined according to the eccentric excircle of the excentric shaft of processing and adjacent cylindrical, it coordinates needs accurately, look for the high point (or low point) of the eccentric inner hole in front and pilot hole need to ensure a specific position relation, after excentric shaft and pilot hole are assembled, only need to fix the position looking for front and can ensure that the eccentric high point of the teeth groove processed or tooth top and excentric shaft aligns.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the schematic diagram of processed excentric shaft.
Embodiment
Fig. 1 is structural representation of the present utility model, and as shown in the figure, the teeth portion processing tool for excentric shaft 7 of the present embodiment, comprises the dowel disc can being set in outside processed excentric shaft 7, the pilot hole that described dowel disc is provided with vertically with processed excentric shaft 7 coordinates, described dowel disc outer side wall is provided with looks for front 5, pilot hole is hole at least two, in one of them, there is bias in hole, its size and eccentric amount need to be determined according to the eccentric excircle of the excentric shaft 7 of processing and adjacent cylindrical, it coordinates needs accurately, look for front 5 need to ensure a specific position relation with the high point (or low point) of the eccentric inner hole in pilot hole, after excentric shaft 7 and pilot hole are assembled, only need to fix the position looking for front 5 and can ensure that the eccentric high point of the teeth groove processed or tooth top and excentric shaft 7 aligns, in the present embodiment, look for and front 5 can arrange a water level gauge, excentric shaft 7 is being added man-hour, water level gauge is utilized to ensure to look for front 5 maintenance level, so that it is guaranteed that the line of the eccentric high point of excentric shaft 7 and low point keeps vertically.
In the present embodiment, described inclined pilot hole comprises centre hole 2 and eccentric hole 3; The described eccentric axial line in hole 3 and the axis parallel of centre hole 2, eccentric hole 3 and centre hole 2 size and eccentric hole 3 need to be determined according to the eccentric excircle (determining eccentric hole 3 size and eccentric amount) of processed excentric shaft 7 and an adjacent cylindrical (determining centre hole 2 size) relative to the eccentric amount of centre hole 2, are convenient to pilot hole and excentric shaft 7 accurately coordinates.
In the present embodiment, described in look for front 5 to be perpendicular to the eccentric hole heart line in hole 3 and the hole determined plane of heart line of centre hole 2; Therefore, after looking for front 5 horizontal positioned, the eccentric high point of excentric shaft 7 keeps vertically with the line of the low point of bias, ensures that the eccentric high point of the teeth groove processed or tooth top and excentric shaft 7 aligns.
In the present embodiment, the outer side wall of described dowel disc is circumferentially distributed with multiple points of teeth groove 4, and the number of point teeth groove 4 is determined by the number of teeth of spline tooth 6, and needs decile.
In the present embodiment, the screw 1 that described dowel disc is disposed radially with eccentric hole 3 is connected, screw 1 can be used for installing dog screw and positioned in eccentric hole 3.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
