Abstract
The utility model relates to a cross-shaped-groove profiling positioning device comprising a chuck, an inner rectangular spline and a tail seat tip. The cross-shaped-groove profiling positioning device is mainly characterized in that a cross-shaped-groove profiling positioning pin is arranged on the inner rectangular spline, the position degree of four grooves of the cross-shaped-groove profiling positioning pin is phi0.01mm-phi0.03mm, the lower end of the cross-shaped-groove profiling positioning pin has a conical angle of 12-16 degrees, and the length of 1.5-3mm. In the utility model, the cross shape is used for centering, the structure is simple, the cost is low, the practicability is strong, and the cross-shaped-groove profiling positioning device can be used for centering of even number of parts with the number of the spline more than two. An inner hole and the inner rectangular spline are connected together with the external cross-shaped-groove processing benchmark by the inner rectangular spline, and the coaxiality of the inner hole, the inner rectangular spline and the external cross-shaped-groove processing benchmark is high.
Description
Technical field
The utility model relates to a kind of positioner of machining, specifically is to utilize the interior rectangular spline of part to do cross recess profiling dowel device.
Background technology
The power shaft and the output shaft of automotive field steering gear part, essential inside and outside rectangular spline or the rice type spline of having.Design of part needs spline and endoporus, water jacket coaxial, and it is reliable that this just need add the man-hour location, reduces error.
Now processing method is: endoporus is to be transformed into cylindrical with the blank center hole, presss from both sides then that cylindrical processes.Interior rectangular spline is a forging molding, when milling the cross water jacket, decides angle with interior rectangular spline, processes outer cross recess.Endoporus and interior rectangular spline and outer cross recess machining benchmark can not get up the coaxial error that exists of three in effective connection like this.
Summary of the invention
The purpose of this utility model overcomes above-mentioned existing shortcoming exactly, provide a kind of simple in structure, cost is low, practical, the cross recess profiling positioner of endoporus and outer cross recess being united with interior rectangular spline.
The utility model comprises chuck, interior rectangular spline and tailstock centre, and main feature is that described interior rectangular spline is provided with cross recess profiling alignment pin; Four groove positions of described cross recess profiling alignment pin degree is Φ 0.01mm-Φ 0.03mm, and cross recess profiling alignment pin lower end is a 12-16 ° of cone angle, and length is 1.5-3mm.
Principle of the present utility model is the profiling location, utilizes cross centering.Simple in structure, cost is low, practical, can be used for of the centering of internal spline number greater than 2 even number class part.Endoporus is connected to three's axiality height with interior rectangular spline and outer cross recess machining benchmark by interior rectangular spline.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is A-A figure of the present utility model
Among the figure: 1, chuck, 2, cross recess profiling alignment pin, 3, interior rectangular spline, 4, tailstock centre, 5, object spare.
The specific embodiment
The utility model comprises chuck 1, interior rectangular spline 3 and tailstock centre 4.At first manufacture cross recess profiling alignment pin 2 according to the interior rectangular spline 3 of object spare 5, cross recess profiling alignment pin 2 is joined the gap with object spare 5 and is not more than 0.02mm, 2 four groove positions of cross recess profiling alignment pin degree is Φ 0.02mm, for convenient mounting and clamping, mill 15 ° of cone angles in cross recess profiling alignment pin 2 lower ends are about length 2mm.
The cylindrical end of this cross recess profiling alignment pin 2 is clipped on the chuck 1, and centering is beated in 0.01mm.Interior rectangular spline 3 ends of object spare 5 are put on this cross recess profiling alignment pin 2, withstood part with tailstock tool top 4 then.
Make cross recess profiling alignment pin 2 according to interior rectangular spline 3,, press from both sides cylindrical again and repair interior rectangular spline 3 end center holes, push up two center hole cylindrical grindings, press from both sides cylindrical processing endoporus then with interior rectangular spline 3 location processing excircles.When milling the cross water jacket, decide angle, process outer cross recess with interior rectangular spline 3.Endoporus and interior rectangular spline 3 and outer cross recess machining benchmark get up by interior rectangular spline 3 effective connections like this, guarantee that the three is coaxial.
