Abstract
The utility model discloses a complex forming surface relative spline shaft machining and positioning device, which comprises a positioning sleeve (1) and a positioning screw (2). A reference plane (3) and a positioning screw hole (4) are machined on the positioning sleeve (1). The positioning screw (2) is connected in the positioning screw hole (4) of the positioning sleeve (1). The utility model has the advantages that the structure is simple and the implementation is easy; and the rapid alignment is realized when the device is used to machine the spline part of a spline shaft and a plurality of complex forming surfaces outside the spline, the positioning is accurate, the machining accuracy and the machining efficiency are greatly improved and the use effect is good.
Description
Technical field
The utility model relates to a kind of processing and positioning device, the relative splined shaft processing and positioning device of especially a kind of complex profile.
Background technology
At present, splined shaft of a great variety, its processing method is also multifarious.Especially collecting splined section becomes a plurality of angles with other a plurality of complicated forming surface (θ 1, θ 2, axially) be the processing method of the splined shaft (as Fig. 3) of one, main adopt dual mode arranged: a kind of is a plurality of complicated forming surface parts of processing earlier, back processing splined section, this kind method trouble when the complicated forming surface relative position of centering spline and other, gear hobbing start position positional accuracy is not high and efficient is lower, clamping inconvenience is unfavorable for promoting the use of.Another kind is first processing splined section, a plurality of complicated forming surface parts of back processing, and this method, the processing splined section is very easy to and precision is high, efficient is high, easy and simple to handle, but trouble and efficient are lower when centering spline and other a plurality of complicated forming surface position.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of complex profile relative splined shaft processing and positioning device, can realize quick centering, and accurate positioning improves machining accuracy and working (machining) efficiency, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model: the relative splined shaft processing and positioning device of a kind of complex profile.Its formation comprises positioning sleeve, dog screw, is processed with a datum level and a location screw on described positioning sleeve; Described dog screw is connected in the positioning screw hole of positioning sleeve.
In the relative splined shaft processing and positioning device of above-mentioned complex profile, the oral area of described positioning screw hole has one section to be the circular hole positioning section, and this circular hole positioning section can be eliminated the error that thread pitch brings.
In the relative splined shaft processing and positioning device of aforesaid complex profile, the head of described dog screw is spherical, is convenient to realize two point locations, self-centering.
In the relative splined shaft processing and positioning device of aforesaid complex profile, the screw thread tail end of dog screw is the cylinder positioning section, and this cylinder positioning section can be eliminated the error that thread pitch brings.
The beneficial effects of the utility model: compared with prior art of the present utility model simple in structure, implement easily.Adopt the utility model can realize quick centering during a plurality of complicated forming surface beyond processing splined section of splined shaft and spline, its accurate positioning can improve machining accuracy and working (machining) efficiency greatly, and result of use is good.

Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment 1.As shown in Figure 1, 2, comprise positioning sleeve 1, dog screw 2.Be processed with a datum level 3 and that is used for definite direction and locate screw 4 on positioning sleeve 1, the oral area of positioning screw hole 4 has one section to be circular hole positioning section 5, and this circular hole positioning section 5 can be eliminated the error that thread pitch brings.The head of dog screw 2 is spherical, is convenient to realize two point locations, self-centering; The screw thread tail end of dog screw 2 is a cylinder positioning section 6, and this cylinder positioning section 6 can be eliminated the error that thread pitch brings.Dog screw 2 is connected in the positioning screw hole 4 of positioning sleeve 1.
During use, positioning sleeve 1 is installed on the cylindrical of splined shaft 7, positioning sleeve 1 and splined shaft 7 cylindrical matched in clearance, its precision is pressed the element precision claimed range and is determined; Dog screw 2 positions can be chosen between two teeth arbitrarily and be tightened in the positioning screw hole 4 of positioning sleeve 1, proofread and correct the datum level 3 on the positioning sleeve 1 then, by part requirement rotational angle, just can be implemented in a plurality of complicated forming surface of processing on any axial angle, the θ angle changes with the part required angle.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
