Description

A kind of printer charging roller grinding double end clamp mechanism
Technical field
The utility model relates to a kind of printer accessory, relates in particular to a kind of printer charging roller grinding double end clamp mechanism.
Background technology
The printer charging roller belongs to the key component in the printer accessory, the rubber roll cylindrical must be through the grinding of rubber roll grinder, for in, low side printer charging roller is when the grinding of rubber roll grinder, all adopt the headstock, tailstock and use concave crown pin two crown grinding process, the rubber roll of being processed is difficult to reach the technical standard that drawing requires, and present domestic rubber roll manufacturer all adopts this technology mode.But the specification requirement of high-end printer charging roller shape and position of related features than in, low side printer charging roller accuracy class improved four times, two traditional crown technology modes can't guarantee the specification requirement of high-end charging roller.Adopt the axle head chamfering cylindrical grinding of concave crown pin two crown charging rollers not meet technological specification, because charging roller is to be that supporting-point is done gyration with the two ends cylindrical in printer, and be to be benchmark with the chamfering during grinding, charging roller iron core work in-process cylindrical and chamfering clamping at twice causes the concentricity of two reference positions in addition; The headstock, tailstock two concave crown pin taperings insert error simultaneously, and the error of headstock spindle revolution and the active thimble rotating accuracy of tailstock, and the existence of above several respects accumulated error has been difficult to process standard compliant high-end charging roller; The grinding force that the technology mode on two crowns bears is very little, has had a strong impact on production efficiency.Secondly, iron mandrel's chamfer is generally 0.5*45 ° in the charging roller grinding, rely on the axial thrust of tailstock spring, the inner conical surface contact that makes the concave crown pin is on the fillet surface of iron core axle head, charging roller is done gyration under the driving of the headstock, whole charging roller relies on axial thrust to drive the workpiece grinding merely under without any the situation of clamping, therefore can only take the grinding depth of trace to reach slower grinding speed processing charging roller in actual production, can't use especially for wide emery wheel; Because iron core rigidity is low, adopt two crown technologies to cause flexural deformation for the charging roller below the 6mm, cause low can't the processing even of having of rubber roll precision of processing.
The utility model content
At above defective, the purpose of this utility model provides and a kind ofly improves machining accuracy, can improve the stability of charging roller in grinding process, can expand the printer charging roller grinding double end clamp mechanism of the scope of application, to overcome many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of printer charging roller grinding double end clamp mechanism, comprise by the headstock, tailstock, charging roller and form two clamping structure, be connected charging roller between this headstock and the tailstock, the described headstock and tailstock have all been installed servomotor, and described servomotor makes two motor constant speed drives by synchronous pulley through synchronous band drive shaft; The sleeve part of the headstock and tailstock is provided with spindle drum, the nose angle contact bearing of main shaft is that " back-to-back " installs, the rear end angular contact bearing is to install " face-to-face ", establishes in two groups of angular contact bearings and adjusts packing ring and make it apply preloading of appointment by round nut; The end of the described headstock and tailstock is provided with high precision collet chuck, and described main shaft and chuck adapter sleeve adopt adjustable syndeton, and described cylinder interior piston body is hollow structure and the chuck connecting rod is installed that a pair of aligning thrust bearing is installed at described chuck connecting rod two ends.
The beneficial effect of printer charging roller grinding double end clamp mechanism described in the utility model is: adopt two clamp mechanism of the headstock, tailstock, meeting more with the cylindrical is the requirement of benchmark processing rubber roll; Adopt high precision collet chuck that the precision of repeated clamping is improved greatly, guaranteed the uniformity of machining accuracy; The clamping force that adopts collet two head-clamp cylindricals than the clamping force of two crown chamferings big more than five times, can adapt to the grinding of wide emery wheel, improved the stability of charging roller in grinding process; Can be installed on the rubber roll grinder of various different models and use, enlarge the scope of application of this mechanism.
