Abstract
The invention discloses a kind of miniature bearing grinding fixture, including matrix and the combination for being fixed on matrix front end, it is characterised in that：A combination neck is machined with the upper front end of described matrix, combination neck a at an acute angle, a is 45 °~80 °, the rear end lower of the combination is a wedge angle, the shape of wedge angle is consistent with the shape of the combination neck, and the wedge angle of the combination is welded into an entirety after being embedded in the combination neck.The front end drift angle that the combination contains diamond is the arc drift angle of arc-shaped.Compared with prior art, the weld of present matrix and combination is designed as oblique angle by the present invention, is embedded in equivalent to welding body inside matrix, is added stability, improves service life.
Description
Technical field
The present invention relates to technical field of bearing processing, specifically a kind of miniature bearing grinding fixture.
Background technology
Conventional grinding fixture is welded by matrix and combination, there is diamond on combination（PCD）.Combination drift angle is
Right angle, in use, because right-angle side is very sharp, workpiece from this right-angle side fall when, it is easy to workpiece
It is cylindrical to cause to scratch, cause the appearance of the bad problem of quality.With the weld of combination it is perpendicular type on matrix, so in length
Time is using process because overall situation about coming off is occurred by different external force effects.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned the deficiencies in the prior art, and provide a kind of combination and be difficult
Come off, a kind of miniature bearing grinding fixture of service life length.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of miniature grinding fixture, including matrix and the combination for being fixed on matrix front end, it is characterised in that：In described matrix
Upper front end is machined with a combination neck, and the combination neck a at an acute angle, a are 45 °~80 °, the rear end of the combination
Bottom is a wedge angle, and the shape of wedge angle is consistent with the shape of the combination neck, and the wedge angle of the combination is embedded in the knot
An entirety is welded into after in fit neck.
The acute angle a is 60 °~70 °.Larger angle can ensure the intensity of weld, and be easy to welding, improve welding
Emphasize.
The front end drift angle that the combination contains diamond is the arc drift angle of arc-shaped.
Compared with prior art, the weld of present matrix and combination is designed as oblique angle by the present invention, equivalent to weldering
Junctor is embedded in inside matrix, adds stability, improves service life.
Support drift angle is designed as arc-shaped, it is to avoid the danger scratched caused by right angle is too sharp keen to workpiece.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 top view；
Fig. 3 is Fig. 1 A portions enlarged diagram；
Fig. 4 is the structural representation of matrix in Fig. 3.
Wherein：1st, matrix；2nd, combination；3rd, diamond；4th, combination neck；5th, arc drift angle.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is elaborated：
As shown in Figure 1 and Figure 2, a kind of miniature grinding fixture, including matrix 1 and the combination 2 for being fixed on the front end of matrix 1.Matrix 1
With combination 2 typically using welding manner connection.A combination neck 4 is machined with the upper front end of matrix 1, the combination card
The a at an acute angle of groove 4, as shown in Figure 4, a are 45 °~80 °, preferably 60 °~70 °.The rear end lower of combination 2 is a wedge angle, wedge angle
Shape it is consistent with the shape of combination neck 4.An entirety is welded into after in the wedge angle insertion combination neck 4 of combination 2.
Front end drift angle of the combination 2 containing diamond 3 is the arc drift angle 5 of arc-shaped, referring to Fig. 3.
In addition it should be understood that, although the present specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
