Abstract
The utility model discloses an eccentric clamp, which comprises a clamp head and a through hole penetrating through the clamp head, wherein the clamp head is asymmetric in structure, and the through hole deviates from a central shaft of the clamp head. As the clamp head is asymmetric in structure and the through hole deviates from the central shaft of the clamp head, eccentric hole machining process is carried out directly after shape machining of a spare part is completed, continuous feeding and machining is realized, a man-made clamping process is omitted, time and production cost are effectively saved, and spare part machining efficiency in batch production is improved.
Description
Technical field
The utility model relates to the Machining Technology field, particularly a kind of eccentric fixture.
Background technology
Eccentric processing is very common a kind of processing technology at present.Usually, factory need to divide two procedures processing when the eccentric orfice of processing securing member, and after the processing parts profile, carry out secondary drilling processing to eccentric orfice again, and need artificial clamping, the feeding trouble, working (machining) efficiency is low when making volume production in enormous quantities.
Anchor clamps are in metal processing, in order to confirming part position exactly, and it are clamped securely, to accept the process equipment of processing.Anchor clamps mainly act on and comprising: the crudy that guarantees workpiece reliably improves working (machining) efficiency, reduces labor intensity, and gives full play to and enlarge the processing performance of lathe.Therefore, anchor clamps occupy important low level in mechanical manufacturing field.
The utility model content
The utility model provides a kind of can realize friction feeding processing, the eccentric fixture of simplifying working process.
For solving the problems of the technologies described above, the utility model provides a kind of eccentric fixture, and the through hole that comprises chuck and run through said chuck, said chuck are unsymmetric structure, and said through hole departs from the central shaft of said chuck.
Preferable; Said eccentric fixture also comprises first groove and second groove; Said first groove comprises the first that is opened in said base and is opened in the second portion on the said chuck, and said first is communicated with second portion, and said second groove is opened on the said chuck.
Preferable, said chuck comprises base and the chuck that is connected with said base.
Preferable, the number of said first groove and second groove is respectively four.
Preferable, the material of said eccentric fixture is a metal material.
Compared with prior art; Because the chuck in the utility model is that unsymmetric structure and said through hole depart from said chuck central shaft; Directly carry out the eccentric orfice processing technology after making the part sharp processing accomplish, realized friction feeding processing, saved artificial clamping operation; Effectively save time and production cost the part processing efficient when having improved volume production in enormous quantities.

Fig. 4 is a part sketch map in the utility model one specific embodiment.
The specific embodiment
For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the specific embodiment of the utility model is done detailed explanation below in conjunction with accompanying drawing.
Please with reference to Fig. 1～3, the utility model provides a kind of eccentric fixture, and said eccentric fixture comprises chuck 1 and the through hole 2 that runs through said chuck 1, and said chuck 1 is a unsymmetric structure, and said through hole 2 departs from the central shaft of said chuck 1.
Wherein, chuck 1 comprises base 11 and the chuck 12 that is connected with said base 11, and in the present embodiment, said base 11 is integrated with chuck 12, so that processing and fabricating.
In addition, said eccentric fixture comprises that also first groove 3 and second groove, 4, the first grooves 3 comprise the first that is opened in base 11 and be opened in the second portion on the chuck 2 that the first of said first groove 3 is communicated with second portion; Said second groove 4 is opened in chuck 2.
In the present embodiment, the number of first groove 3 and second groove 4 is respectively four, and the number of the groove during actual production is determined that by concrete process conditions the utility model will not limit this.
During practical implementation, the chuck 1 of eccentric fixture is fixed on the lathe part 5 to be processed; As shown in Figure 4, be fixed in the through hole 2 of eccentric fixture, because the existence of first groove 3 and second groove 4; For eccentric fixture provides tension force, make that the part to be processed 5 in the through hole is able to fix.The eccentric structure size of eccentric fixture changes with the variation of processing parts, but through hole 2 departs from the distance of chuck 1 central shaft usually in 2.54cm.
Because the chuck in the utility model is a unsymmetric structure; And said through hole departs from said chuck central shaft, directly carries out the eccentric orfice processing technology after making the part sharp processing accomplish, and has realized friction feeding processing; Saved artificial clamping operation, effectively saved time and production cost.
In addition, the utility model eccentric fixture is a metal material, has volume characteristics little, in light weight, simple in structure, easy to use; And the part similar with type among the utility model embodiment all can be realized processing continuously through eccentric fixture or its modification of the utility model, can save the process time of property product in batches greatly
Obviously, those skilled in the art can carry out various changes and modification to utility model and not break away from the spirit and the scope of the utility model.Like this, if these of the utility model are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these change and modification.
