Abstract
The invention discloses a novel special shaft sleeve type eccentric clamping device which comprises a clamping sleeve, wherein the clamping sleeve is a cylinder; a circular clamping groove is formed on the front end face of the clamping sleeve; the axis of the clamping groove is misaligned with that of the clamping sleeve; a through hole is formed in the bottom end face of the clamping groove; three thread though holes are uniformly distributed in the outer circumferential surface of the clamping groove at an angle of 120 degrees with the axis of the clamping sleeve as the circle center. By adopting the technical scheme provided by the invention, eccentric workpieces are simple in clamping and small in error and are easy to align; in addition, the novel special shaft sleeve type eccentric clamping device is suitable for batch production.
Description
Technical field
The present invention relates to the fixture positioning field, be specifically related to a kind of Novel shaft shell type Special Eccentric clamping device.
Background technology
Eccentric element is applied very extensive on plant equipment, but the processing technology of eccentric element is more complicated, subject matter is the more difficult eccentric throw of getting hold of, difficulty reaches corresponding tolerance, the traditional vehicle eccentric part: a kind of is to utilize the scroll chuck clamping, first good the cylindrical car of the part of the non-eccentricity in eccentric work piece, at any one claw of chuck and workpiece, connect between place's face subsequently, the pad lastblock is chosen the pad of thickness in advance, calibrated bus and eccentric throw, and, after Workpiece clamping, get final product turning.Another kind is to utilize the four-jaw chuck clamping, and the workpiece that pulls line is contained on chuck.When clamping, first regulate two pawls of chuck, make it be asymmetric position, another two pawls become symmetric position, and workpiece off-centre operation line, in chuck central authorities, is put tablet and scribing block well on bed surface, and tip alignment off-centre operation line is proofreaied and correct off-centre operation.Then tip alignment cylindrical horizontal line, inspection AQL line level whether, rotate 90 ° to workpiece from left to right, use the same method and check another horizontal line, then fastening card base and check clamping workpiece situation, after the workpiece calibration, four paws is tightened one time again, can be cut.
Above-mentioned two kinds of methods are all the processing methods of relatively commonly using, but existent defects all, and clamping is cumbersome, is not easy centering, easily produces error.And be not suitable for producing in batches.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of Novel shaft shell type Special Eccentric clamping device is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of Novel shaft shell type Special Eccentric clamping device, comprise chuck, described chuck is cylinder, be provided with circular clip slot on described chuck front end face, described clip slot axle center does not overlap with described chuck axle center, be provided with through hole at described clip slot bottom face, take the axle center of described chuck to be uniformly distributed and to be provided with three tapped through holes with hexagonal angle as the center of circle on described clip slot periphery.
Further, the axle center of described through hole and the axis coinciding of described chuck, described clip slot axle center and described chuck distance of shaft centers are from being 5-8mm.
Further, also comprise claw, trip bolt, eccentric work piece and lathe tool, described workpiece is placed in described clip slot, and described trip bolt is by the fastening described eccentric work piece of described tapped through hole, and described chuck is fixed by described claw.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, the eccentric work piece clamping is simple, easy centering, and error is little, and is applicable to batch production.
The accompanying drawing explanation
Fig. 1 is assembly structure schematic diagram of the present invention;
Fig. 2 is the chuck front view;
Fig. 3 is the chuck left view.
Number in the figure explanation: 1, chuck, 2, clip slot, 3, through hole, 4, tapped through hole, 5, claw, 6, trip bolt, 7, eccentric work piece, 8, lathe tool.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of Novel shaft shell type Special Eccentric clamping device, comprise chuck 1, described chuck 1 is cylinder, be provided with circular clip slot 2 on described chuck 1 front end face, described clip slot 2 axle center do not overlap with described chuck 1 axle center, at described clip slot 2 bottom faces, are provided with through hole 3, take the axle center of described chuck 1 to be uniformly distributed and to be provided with three tapped through holes 4 with hexagonal angle as the center of circle on described clip slot 2 peripheries.
Further, the axis coinciding of the axle center of described through hole 3 and described chuck 1, described clip slot 2 axle center and described chuck 1 distance of shaft centers are from being 5-8mm.
Further, also comprise claw 5, trip bolt 6, eccentric work piece 7 and lathe tool 8, described workpiece 7 is placed in described clip slot 2, and described trip bolt 6 is by the fastening described eccentric work piece 7 of described tapped through hole 4, and described chuck 1 is fixing by described claw 5.
Principle of the present invention:
The present invention has designed supporting chuck 1, by this chuck 1, carries out clamping processing, saved the time of a lot of centerings, and the requirement of precision has also improved a lot.Utilize this chuck 1 design concept we can also process much more more eccentric work pieces, be mainly that the fixture by designing different eccentric throws carries out clamping.The manufacture of Cycle with eccentric wheels fixture is simple, therefore can extensively promote, and increases economic efficiency.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
