Abstract
The invention relates to an auxiliary part for machining of a slender shaft, in particular to a bearing frame for machining of a shaft-shaped workpiece for fixing a slender-shaft workpiece. The bearing frame comprises a body, a horizontal through hole is formed in the upper part of the body, and a plurality of radially stretchable thimbles are uniformly distributed in the through hole. With the adoption of the bearing frame, the clamping stiffness of the workpiece is improved, the deformation of the workpiece in the length direction is prevented, the error due to vibration is reduced, the workpiece machining accuracy is improved, and the yield is improved.
Description
Technical field
The present invention relates to a kind of machining accessory of slender axles.Specifically, be a kind of shaft-like workpiece processing bearing support of elongate shaft-like work.
Background technology
All know in field of machining, slender axles so its rigidity is relatively poor, easily produce vibration because the ratio of its Workpiece length and diameter mostly more than 20, belongs to long axial workpiece in working angles, also can produce distortion at length direction because of heat in metal cutting.Because to cover time of a cutter longer, can cause the wear extent of cutter larger in addition, also cause the form and position tolerance precision of workpiece and surface roughness difficulty reach drawing requirement, produce too much substandard product.
Summary of the invention
The problem to be solved in the present invention provides a kind of shaft-like workpiece processing bearing support.This bearing support has increased the rigidity that clamps of workpiece, has prevented that workpiece from the distortion that length direction produces, having reduced the error that is produced by vibration, has increased the precision of processing work, has improved qualification rate.
For addressing the above problem, take following technical scheme:
Bearing support is used in shaft-like workpiece processing of the present invention, it is characterized in that comprising body, and the top of described body is provided with horizontal through hole, is evenly equipped with the thimble of a plurality of expandables in this through hole.
The further improvement of the present invention scheme be the quantity of described thimble more than or equal to 3, thereby can better shaft-like workpiece be located.
Take such scheme, have the following advantages:
Owing to having adopted shaft-like workpiece of the present invention processing use bearing support, can reasonably use to shaft-like workpiece processing with bearing support as supplemental support, to increase the install rigidity of workpiece, prevent that workpiece is because vibrating or being got rid of curved because of the effect of centrifugal force.
Description of drawings
Fig. 1 is structural representation of the present invention;
The specific embodiment
As shown in Figure 1, shaft-like workpiece processing of the present invention comprises body 1 with bearing support, and the top of described body 1 is provided with horizontal through hole 3, is evenly equipped with the thimble 2 of a plurality of expandables in this through hole 3.The quantity of described thimble 2 is more than or equal to 3, and the quantity of thimble 2 described in this enforcement power is 3.
Before workpiece 4 is loaded onto center support, must go out at the workpiece 4 blank middle vehicles of needs processing one section groove with the described thimble 2 of support.When turning, this thimble 2 and workpiece 4 contact positions are apply oil often.In order being that thimble 2 keeps good just contacting with workpiece 4, also can between thimble 2 and workpiece 4, to add one deck gauze or grinding agent in addition, to grind obvolvent.Because before workpiece 4 is loaded onto on the centre frame, this workpiece 4 blanks middle part car goes out the groove of one section supporting thimble 2, from but its surface roughness and deviation from cylindrical form reduce, improved the precision of workpiece 4.
Claims (2)
