Description
Technical field
The utility model relates to auto parts and components production equipment, is specifically related to a kind of thin wall cylinder cover clamping device.
Background technology
The thin wall cylinder cover processing technology for inner hole of prior art is thick hinge → finish ream → rough honing → microhoning.Be subject to the restriction of shaping reamer accuracy of manufacture quality aspect owing to finish reaming technique, the endoporus circularity after cylinder jacket hinge can only reach IT9 level, and leaves Honing process surplus 0.3-0.35 millimeter for.Along with engine manufacturer improves the quality requirement of parts, cylinder sleeve technology standard rises to state four standard by state three, and above-mentioned technological ability index has not reached the requirement of state four standard.
Trace it to its cause, be mainly in cylinder jacket clamping process, because stress is undesirable and cause workpiece to produce deformation, thus reduce machining accuracy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of thin wall cylinder cover bore hole air clamper, and can carry out stabilizing grip to thin wall cylinder cover, the circumferential uniform force of workpiece, does not produce deformation after clamping, thus improves machining accuracy.
For solving the problems of the technologies described above, thin wall cylinder cover bore hole air clamper of the present utility model, comprise clamp body, it is characterized in that: described clamp body inner chamber bottom is provided with backing plate, the lower tapered sleeve of band taper hole is provided with above described backing plate, clamp body inner chamber above described lower tapered sleeve is radially disposed with elastic opening cover, spring housing, described spring housing upper end be provided with band taper hole upper tapered sleeve, described spring housing upper and lower side respectively with described upper tapered sleeve, lower tapered sleeve cone match; At least three cover hold down gags are evenly equipped with along the circumferential of described clamp body, described hold down gag comprises cylinder, also comprise the cylinder block be arranged on above cylinder, described cylinder block is provided with pressure arm by bearing pin, the piston rod of described cylinder and described pressure arm Matching installation; One end of described pressure arm extends to clamp body luminal border, is provided with extension spring between the other end of pressure arm and cylinder block.
Described upper tapered sleeve, lower tapered sleeve hole taper 60 degree, upper tapered sleeve, lower tapered sleeve and spring housing two ends cone match, contact surface is not less than 85% of spring housing cone surface which area.
After have employed technique scheme, workpiece is placed in elastic opening cover, and elastic opening cover is coated in spring housing, pushes pressure arm by the piston rod of cylinder, radial pressure is converted to through axial compressive force through upper tapered sleeve, lower tapered sleeve, thus through circumferential, clamping being carried out to workpiece, clamping process Elastic opening sleeve absorption pressure, workpiece itself is undeformed, clamping is firm, circumferential uniform force, does not produce deformation after clamping, thus improves machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of thin wall cylinder cover bore hole air clamper of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the partial enlarged drawing of clamp body 1 part in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, Figure 2, Fig. 3 is visible, thin wall cylinder cover bore hole air clamper of the present utility model, comprise clamp body 1, described clamp body 1 inner chamber bottom is provided with backing plate 2, the lower tapered sleeve 3 of band taper hole is provided with above described backing plate 2, clamp body 1 inner chamber above described lower tapered sleeve 3 be radially disposed with elastic opening cover 4, spring housing 5, described spring housing 5 upper end be provided with band taper hole upper tapered sleeve 6, described spring housing 5 upper and lower side respectively with described upper tapered sleeve 6, lower tapered sleeve 3 cone match; Three cover hold down gags are evenly equipped with along the circumferential of described clamp body 1, described hold down gag comprises cylinder 7, also comprise the cylinder block 70 be arranged on above cylinder 7, described cylinder block 70 is provided with pressure arm 8 by bearing pin, piston rod 71 and described pressure arm 8 Matching installation of described cylinder 7; One end of described pressure arm 8 extends to clamp body 1 luminal border, is provided with extension spring 9 between the other end of pressure arm 8 and cylinder block 70.
Be provided with diamond fine boring machine boring bar 11 above described clamp body, described diamond fine boring machine boring bar 10 end is provided with adjustable boring tool 110.
Clamp body 1 endoporus reaches IT4 level, roughness Ra 0.4, with upper tapered sleeve 6, lower tapered sleeve 3 cylindrical matched in clearance through inner circle mill finished size precision.Upper tapered sleeve 6, lower tapered sleeve 3 hole taper 60 degree, with spring housing 5 two ends cone match, contact surface is not less than 85%.In spring housing 5, aperture inner circle mill accurate to dimension reaches IT4 level, roughness Ra 0.4, overlaps 4 cylindrical matched in clearance with elastic opening.Elastic opening overlaps 4 hole size precision and reaches IT4 level, roughness Ra 0.4 and workpiece 10(cylinder jacket) cylindrical matched in clearance, fit clearance tolerance 0.09-0.11 millimeter, elastic opening overlaps 4 Wall-Thickness Differences should be not more than 3 millimeters, so that elastic opening cover 4 under external force, produce elastic deformation and do not affect the distortion of processing work, processing exhaust hood cover roundness of external circle and straightness error little, IT7 level can be reached.
Clamping device operating principle: by workpiece 10(cylinder jacket) put into elastic opening cover 4, the boss lower edge on described cylinder jacket top is placed on elastic opening and overlaps 4 upper ends, press Pneumatic button, the piston rod 71 of cylinder 7 rises, 3 pressure arms 8 depress tapered sleeve 6 simultaneously, upper tapered sleeve 6 moves down, spring housing 5 endoporus shrinks, elastic opening 4 endoporus shrinks, workpiece 10 cylindrical reaches clamping, press diamond fine boring machine processing button, now processing work endoporus, after workpiece completion, press Pneumatic button, piston rod 71 declines, 3 pressure arms 8 rise simultaneously, spring housing 5 and elastic opening cover 4 get back to free state after external force loses, workpiece unclamps, a fabrication cycles completes.
