Abstract
The utility model relates to the technical field of the eccentric bushings and specifically relates to a novel clamp for producing eccentric bushing parts. A step capable of quickly positioning a workpiece is arranged at the left end of a cone-shaped core shaft; a split eccentric expansion sleeve is matched with the external cone of the cone-shaped core shaft; a linked locking device is connected with the cone-shaped core shaft by use of screw threads; the step is clamped in a groove of the split eccentric expansion sleeve. The clamp is suitable for various bushing parts; axial movement is converted into radial change of the expansion sleeve by virtue of spiral transmission so that quick expansion and separation can be realized; the split eccentric expansion sleeve is tightened by using a spring ring and thus prevented from becoming loose, and automatic separation of the expansion sleeve from the workpiece is realized; in order to improve the cutting efficiency and accuracy of thin-wall parts and avoid axial movement of the parts, the step smaller than the outer diameter of the part is arranged at the left side of the device and used for bearing axial cutting force; the clamp is high in eccentric control accuracy, and succeeds in solving the plastic deformation of the expansion sleeve and prolonging the service life of the clamp; the clamp is capable of bearing large axial force, low in deformation for bushing parts, in particular thin-wall parts, and more convenient and faster for use in clamping.
Description
Technical field
The utility model relates to eccentric bushing technical field, specifically a kind of Novel eccentric cover part production fixture.
Background technology
Existing a lot of eccentric cover parts, the method of conventional machining eccentric bushing is cumbersome, and positional precision is difficult to ensure, the fixture centering location of existing eccentric bushing processing is not accurate enough, control eccentric precision not high, cannot solve expansion set plastic deformation, the service life of fixture is shorter, can not bear larger axis to power, can not look at present a simple method and can realize rapid clamping.
Therefore, design and can improve machining accuracy for overcoming the deficiency of above-mentioned technology, a kind of Novel eccentric cover part production fixture of enhancing productivity, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Novel eccentric cover part production fixture, and it is simple in structure, easy to use, can improve machining accuracy, enhances productivity, and has extraordinary practical value.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel eccentric cover part production fixture, it is characterized in that: fixture is made up of taper mandrel, the eccentric expansion set of split, linkage locking device, turn, taper mandrel left end is provided with can be by the workpiece step of location rapidly, the eccentric expansion set of split coordinates with the outer cone of taper mandrel, linkage locking device adopts screw thread to be connected with taper mandrel, and step is stuck in the groove of the eccentric expansion set of split.
Further, the eccentric expansion set arranged outside of described split has the turn that eccentric split expansion set can be tied tight.
The beneficial effects of the utility model are:
1, the utility model is simple in structure, centering accurate positioning, convenient mounting and clamping, be applicable to all kinds of cover parts, especially shape, position, the thin-wall sleeve class that dimension precision requirement is high or the clamping of eccentric cover parts, the radial variations that changes expansion set into will be moved axially by worm drive, thereby realize swelling rapidly and separate, adopt turn that eccentric split expansion set is tied tight, prevent that split expansion set is loose, and realize expansion set and separate with the automatic of workpiece, in order to improve thin-wall part stock-removing efficiency and precision, avoiding part to produce moves axially, this device left side is provided with a step that is less than part external diameter, bear axial cutting force.
2, the utility model centering accurate positioning, controls eccentric precision high, has solved expansion set plastic deformation, extends fixture service life, can bear larger axis to power, and to cover parts, especially the distortion of thin wall component is little, and clamping uses more convenient and quicker.

Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is a kind of Novel eccentric cover of the utility model part production clamp structure schematic diagram, fixture is made up of taper mandrel 1, the eccentric expansion set 2 of split, linkage locking device 3, turn 4, taper mandrel 1 left end is provided with can be by the workpiece step of location rapidly, the eccentric expansion set 2 of split coordinates with the outer cone of taper mandrel 1, linkage locking device 3 adopts screw thread to be connected with taper mandrel 1, and step is stuck in the groove of the eccentric expansion set 2 of split, eccentric expansion set 2 arranged outside of split have the turn 4 that eccentric split expansion set 2 can be tied tight.
This device adopts the mode of eccentric bushing swelling endoporus to realize clamping, eccentric bushing adopts the mode of split, in order to prevent being scattered of split eccentric bushing, use turn 4 to tie tight, by relatively moving between taper mandrel 1 and the eccentric expansion set 2 of split, realize radially swelling, adopt worm drive to rotatablely move simultaneously and be transformed into rectilinear movement.
The utility model is waited in use, first by the inner hole sleeve of eccentric bushing part 5 to be processed on the eccentric expansion set 2 of the split of this fixture, and the left side of part and taper mandrel 1 step are leaned on real, then turn the square tenon on linkage locking device 3 the right, thereby processed eccentric bushing part 5 is clamped, otherwise, can be by part to be processed removal.
The utility model is simple in structure, centering accurate positioning, convenient mounting and clamping, be applicable to all kinds of cover parts, especially shape, position, the thin-wall sleeve class that dimension precision requirement is high or the clamping of eccentric cover parts, the radial variations that changes expansion set into will be moved axially by worm drive, thereby realize swelling rapidly and separate, adopt turn 4 that eccentric split expansion set is tied tight, prevent that split expansion set is loose, and realize expansion set and separate with the automatic of workpiece, in order to improve thin-wall part stock-removing efficiency and precision, avoiding part to produce moves axially, this device left side is provided with a step that is less than part external diameter, bear axial cutting force, the utility model centering accurate positioning, control eccentric precision high, solve expansion set plastic deformation, extend fixture service life, can bear larger axis to power, to cover parts, especially the distortion of thin wall component is little, clamping uses more convenient and quicker.
