Description
Technical field
The utility model belongs to hole class technical field of mechanical processing, in particular to a kind of self-locking reverse side spot facer.
Background technique
At present when processing gusset reverse side counterbore, using using eccentric single head reverse boring cutter access aperture bottom, by cutter from
Turn the revolution plus workpiece around Milling Machining, first because boring cutter is cut using single-blade and blade is effectively cut wide cutting-in and limited, more than processing
The a large amount of cutting time is needed when measuring big, processing efficiency is low, also because of boring cutter eccentric feed, so knife bar diameter is influenced by design,
Knife bar cross section is small, and it is insufficient to process rigidity, causes in processing that vibration cutting is big, and bore dia size is unstable, and hole surface is of poor quality
Or hole wall generates step, causes processing part rejection.
Utility model content
The utility model for the technical problems in the prior art, provides a kind of self-locking reverse side spot facer, reachable
To fast self-locking is realized, gusset class reverse side counterbore processing efficiency can be improved, improve the position precision in processing hole, improve inner hole and add
The beneficial effect of work surface quality.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of self-locking reverse side spot facer, packet
Include knife handle (1), knife bar (2), anti-countersink (3), hole body (5), elastic steel ball (6), arc groove (7)；It is set below the knife handle (1)
Have workpiece (4), the top of workpiece (4) is equipped with the hole body (5) of perforation；The bottom end of the knife handle (1) is fixed with knife bar (2), institute
Knife bar (2) are stated across hole body (5)；The lower part insertion of the knife bar (2) is equipped with elastic steel ball (6)；The anti-countersink (3) is from top
Center to bottom center be perforation channel；The lower part of the knife bar (2) pass through anti-countersink (3) channel and with anti-countersink (3)
It is fixedly connected.
Preferably, the through channel side wall of the anti-countersink (3) is equipped with arc groove (7).
Compared with prior art, beneficial effect possessed by the utility model is: the utility model can realize fast self-locking,
There are multiple teeth to be cut, good processing stability can be improved gusset class reverse side counterbore processing efficiency, while improve processing hole
Position precision solves the problems, such as knife phenomenon of shaking caused by arbor stiffness deficiency, improves inner hole machined surface quality, reduces work pieces process
It is bad, improve processing quality.

Specific embodiment
It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model
Example is applied to elaborate to the utility model.
The embodiments of the present invention disclose a kind of self-locking reverse side spot facer, as shown in the figure comprising knife handle 1, knife
Bar 2, anti-countersink 3, hole body 5, elastic steel ball 6, arc groove 7；The lower section of knife handle 1 is equipped with workpiece 4, and the top of workpiece 4 is equipped with perforation
Hole body 5；The bottom end of knife handle 1 is fixed with knife bar 2, and knife bar 2 passes through hole body 5；The lower part insertion of knife bar 2 is equipped with elastic steel ball 6；
Anti- countersink 3 is the channel of perforation from top center to bottom center；The lower part of knife bar 2 pass through anti-countersink 3 channel and with anti-ream
Knife 3 is fixedly connected.
In the present embodiment, the through channel side wall of anti-countersink 3 is equipped with arc groove 7.
In the present embodiment, when part processes reverse side counterbore, via diameter is smaller, and depth is deeper.
In the present embodiment, boring cutter enters via hole using rod-type, and maximum magnitude to the greatest extent improves boring bar diameter, improves and effectively adds
Times diameter of work hole depth, arbor stiffness improves therewith, reduces knife bar stress deformation in cutting, and cutter head sword number is also singly cut by original
It cuts sword cutting and is changed to multi-tool edge cutting, and be evenly distributed design using cutting edge；And the prior art is then used in processing
Eccentric boring cutter processing, has had exceeded effective times of diameter range of stable hole machined, is unable to satisfy the processing dimension requirement of needs.
In the present embodiment, simultaneous manufacturing mode is realized, programming is simple, stablizes machining, improves hole machined
Stock-removing efficiency；And the rotation that the prior art uses adds revolution Design Processing, programming is complicated, and cutting line is long, processing effect
Rate is low.
In the present embodiment, the bottom surface of anti-countersink 3 and knife bar 2 are positioned, and play play positioning support, while and Elastic Steel up and down
The laterally and tightly propped power of pearl 6 plays knife bar fixed function, and completes self-locking function.The maximization of knife bar designs, and can be improved processing
Rigidity and cutting stability.
The utility model is described in detail above by embodiment, but the content is only showing for the utility model
Example property embodiment, should not be considered as limiting the scope of the present invention.The protection scope of the utility model is by right
Claim limits.It is all to utilize technical solution described in the utility model or those skilled in the art in the utility model technology
Under the inspiration of scheme, in the essence and protection scope of the utility model, designs similar technical solution and reach above-mentioned skill
Art effect, or to all the changes and improvements made by application range etc., the patent that should still belong to the utility model is contained
Within lid protection scope.It should be noted that part and this reality are omitted in the explanation of the utility model in order to clearly be stated
With novel protection scope without directly apparent association but the statement of component well known by persons skilled in the art and processing.
