Abstract
The utility model discloses an orifice grinding polishing machine which comprises a pneumatic grinder and a rotating shaft. The orifice grinding polishing machine is characterized in that the end of the rotating shaft is fixedly provided with a circular emery cloth piece through a screw. The orifice grinding polishing machine can overcome the defect of workpiece deformation caused by gravity, greatly improve detection precision, be completely contacted with a processed surface, and meet the demands of smoothness and roughness. The emery cloth piece can not fall off easily and is convenient to replace, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of polishing, polishing tool, especially for the sanding and polishing machine in crankshaft oil hole aperture.
Background technology
The straight oilhole of the trunnion of automobile crane, crank pin surface, inclined oil hole of air, the intersection of its aperture and axial plane is the three-dimensional curve of a sealing, adding the requirement in man-hour to aperture intersection rounding, form the face that passes through mutually, be connected with axial plane smoothly, surface roughness Ra 0.8 μ m concentrates to avoid stress; Manufacturing process originally adopts scraper scraping, air operated portable grinder clamping fine taper wheel grinding more, perhaps pass through its collet clamping rotating shaft with air operated portable grinder, add rubber blanket at the rotating shaft end face, add the emery cloth sheet at rubber blanket, firmly the emery cloth sheet is pressed to surface to be machined, utilize the distortion of rubber blanket, make the emery cloth sheet be fitted in irregular passing through mutually on the face, carry out sanding and polishing; Because after rubber blanket added emery cloth and firmly presses down, the flexibility of emery cloth significantly was restricted, can't with pass through mutually face and fully contact, all can not process so that much pass through mutually face, the smoothness of passing through mutually face is also not ideal enough, and the emery cloth sheet is when motion, easily come off, affect operating efficiency.
The utility model content
The purpose of this utility model is for the prior art above shortcomings, a kind of aperture sanding and polishing machine is provided, and it can fully contact machined surface, has guaranteed smoothness and roughness requirement, and emery cloth sheet difficult drop-off, replacing are conveniently, improved operating efficiency.
For achieving the above object, a kind of aperture of the present utility model sanding and polishing machine comprises air operated portable grinder, rotating shaft, it is characterized in that being installed with circular emery cloth sheet in the termination of rotating shaft by screw.
During use, rotating shaft about aperture place does, side-to-side movement, and High Rotation Speed; Because circular emery cloth sheet is to be fixed on the rotating shaft, and the centrifugalization of emery cloth sheet and self elasticity, emery cloth flexibly with machined surface pass through mutually that height point on the face contacts, grinding, until the whole sanding and polishings of whole machined surface are finished, guaranteed smoothness and roughness requirement; And emery cloth sheet difficult drop-off, replacing are conveniently, and this machine need not accurate location when work, improved operating efficiency.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, this aperture sanding and polishing machine comprises the rotating shaft 2 that the collet of air operated portable grinder 1, air operated portable grinder 1 connects, and is installed with circular emery cloth sheet 4 in the termination of rotating shaft 2 by screw 3.
During use, rotating shaft 2 about aperture place does, side-to-side movement, and High Rotation Speed; Because circular emery cloth sheet 4 is to be fixed on the rotating shaft 2, and the centrifugalization of emery cloth sheet and self elasticity, emery cloth flexibly with machined surface pass through mutually that height point on the face contacts, grinding, until the whole sanding and polishings of whole machined surface are finished, guaranteed smoothness and roughness requirement; And emery cloth sheet 4 difficult drop-offs, replacing are conveniently, and this machine need not accurate location when work, improved operating efficiency.
