Abstract
The utility model relates to a kind of eccentric part clamp for machining, for clamping workpiece, the outside diameter of workpiece is D, including cylindric clamp body, and the outside diameter of clamp body is D2, the diameter of bore of clamp body is D1, D1 > D, clamp body are sheathed on the outside of workpiece, and fixture body side surface, which is offered, to be passed through for screw and resist workpiece so that workpiece lock onto the threaded hole of clamp body inner wall, the eccentric shaft or eccentric orfice that the workpiece end face processing eccentricity clamped by clamp body is E, D1=D+2E.The beneficial effects of the utility model are: the processing is simple, reliable for fixture, and accuracy is high, not only can guarantee the higher center of required precision away from but also can also improving production efficiency and product quality.
Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to a kind of eccentric part clamp for machining.
Background technique
In machining, fixture used in vehicle eccentric work piece usually has three-jaw self-centering chuck, four-jaw chuck, double
Heavy truck disk, floral disc, special fixture etc..When encountering some typical parts, if processing on horizontal lathe, four paws list is usually just used
The method of chuck and three-jaw self-centering chuck shimming is moved to clamp.It was verified that this method is of poor quality, low efficiency, and difficult
The axis of (eccentric shaft with eccentric orfice) is parallel so that two eccentric bodies.
Utility model content
Technical problem to be solved by the utility model is: based on the above issues, providing a kind of eccentric part clamp for machining.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of eccentric part clamp for machining, for pressing from both sides
Clamping of workpieces, the outside diameter of workpiece are D, including cylindric clamp body, and the outside diameter of clamp body is D2, and the inner hole of clamp body is straight
Diameter is D1, D1 > D, and clamp body is sheathed on the outside of workpiece, fixture body side surface offer passed through for screw and resist workpiece so that
Workpiece lock onto the threaded hole of clamp body inner wall, the eccentric shaft or inclined that the workpiece end face processing eccentricity clamped by clamp body is E
Heart hole, D1=D+2E.
Further, clamp body is parallel with the axis of workpiece.
Further, the female coaxial of the setting of the female coaxial of eccentric shaft and clamp body or eccentric orfice and clamp body is set
It sets.
Further, the outer circle of clamp body and female coaxial are arranged.
The beneficial effects of the utility model are: the processing is simple, reliable for fixture, and accuracy is high, not only can guarantee precision
More demanding center is away from and can also improving production efficiency and product quality.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing.
Fig. 1 is the connection figure of workpiece and clamp body；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of clamp body；
Wherein: 1. workpiece, 2. clamp bodies, 3. screws.
Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
A kind of eccentric part clamp for machining as shown in Figures 1 to 3, for clamping workpiece 1, the outside diameter of workpiece 1 is D, packet
Include cylindric clamp body 2, the outside diameter of clamp body 2 is D2, and the diameter of bore of clamp body 2 is D1, D1 > D, and clamp body 2 is arranged
In 1 outside of workpiece, 2 side of clamp body, which is offered, to be passed through for screw 3 and resists workpiece 1 so that workpiece 1 is lock onto clamp body 2
The threaded hole of wall, the eccentric shaft or eccentric orfice that 1 end face of the workpiece processing eccentricity clamped by clamp body 2 is E, D1=D+2E.
Clamp body 2 is parallel with the axis of workpiece 1, under the action of screw 3, the inner hole inner wall of 1 joint jig body 2 of workpiece,
Screw 3 is tightened, by 1 locking positioning of workpiece.
The female coaxial of the setting of the female coaxial of eccentric shaft and clamp body 2 or eccentric orfice and clamp body 2 is arranged.Adding
The whole axis around clamp body 2 of working hour, clamp body 2 and workpiece 1 rotates, the eccentric shaft or eccentric orfice processed therefore also with folder
Specific 2 is coaxial.
The outer circle and female coaxial of clamp body 2 are arranged.
The production of eccentric part clamp for machining is simple, only gets on the bus a cylindrical body in horizontal lathe, further according to workpiece to be processed
The size of outer circle processes a hole, forms cylindrical shape, and a threaded hole is then processed on cylinder can be used, as shown in Figure 2.
The size of fixture inner hole D1 calculates as follows: if the outside diameter of workpiece is D, bias to be processed on the workpiece
Axis, hole eccentricity be E, then fixture inner hole calculate as shown in Figure 1: D1/2=D/2+E, i.e. D1=D+2E.
It is mutually eccentric to can be seen that either Kong Yukong from above analysis, outer circle and outer circle be mutually eccentric or outer circle
Mutually eccentric with inner hole, as long as processing on horizontal lathe, when workpiece rotation, only a center line can be with lathe spindle
Rotation center be overlapped, and another center line is to be subject to its coincident central line, is displaced an eccentricity to radial direction.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
