Abstract
The utility model provides a knurling tool, it includes the base, tool arm, locking device and knurlizer, base top both sides hinge has two tool arms, and the free end of tool arm hinges there is the knurlizer, and the middle part of tool arm is provided with the guiding hole, and the guided way that sets up on the base passes from the guiding hole, still is provided with in the guiding hole the fixed locking device of two tool arms. This knurling tool can realize the exterior annular knurl of the little and long machined part of diameter and can reduce annular knurl in -process lathe atress, avoids the lathe to destroy.
Description
Technical field
The utility model relates to a kind of cutter for processing annular knurl.
Background technology
Existing lathe annular knurl technology can not solve the annular knurl operation of small diameter long workpiece, because existing knurling tool is that the stressed meeting of one side makes the workpiece of minor diameter occur man-hour bending and can not process adding in operation.And existing lathe knurling tool is because being the stressed extruding annular knurl of one side, and in process, the opposite force of cutter to the longitudinal supporting plate of lathe is very large, is easy to the screw rod destroying longitudinal supporting plate.
Utility model content
In order to solve Problems existing in background technology, the utility model provides a kind of knurling tool, and this knurling tool can realize the appearance annular knurl of the little and long workpiece of diameter and can to reduce lathe in annular knurl process stressed, avoids lathe to destroy.
For achieving the above object, the utility model adopts following technical scheme:
A kind of knurling tool, comprise pedestal, tool arm, locking device and knurling tool, both sides, described pedestal top are hinged with two tool arms, the free termination of tool arm is hinged with knurling tool, the middle part of tool arm is provided with pilot hole, and the guided way be arranged on pedestal passes from pilot hole, is also provided with the fixing locking device of two tool arms in pilot hole.
Described pedestal comprises the substrate of strip, cross connecting plate and guided way, and the top of substrate side is provided with cross connecting plate, and the top of substrate opposite side is provided with the guided way of arc, and engaging lug is stretched out in the both sides of cross connecting plate.
The termination of tool arm is provided with transverse concave groove, Snap joint ear in transverse concave groove, and jointed shaft is through the left and right sides after transverse concave groove and engaging lug, tool arm being hinged on cross connecting plate.
Described locking device is be arranged on locking column in pilot hole and stud, and locking column has screw, stud from the screw two locking columns through and be spirally connected with locking column.
The end of described stud is provided with a handwheel.
The articulated manner of described knurling tool and tool arm is: the free termination of tool arm is provided with groove, by the hinged knurling tool of rotating shaft in groove.
The beneficial effects of the utility model are: by changing the structure of original cutter, make original unidirectionally extruded annular knurl be altered to new formula (jaw type) of embracing and clamp annular knurl, making workpiece simultaneously stressed up and down, to avoid workpiece to produce because of single load bearing bending, simultaneously because new-type knurling tool does not adopt unidirectionally extruded annular knurl operation, opposition would not be produced to longitudinal supporting plate of lathe and can not cause damage to lathe.Protect lathe, improve process velocity.This knurling tool processing major axis 2m-diameter is when 100mm reticulate pattern 1.2mm, and speed is compared with conventional knurling tool and wanted fast 3-5 doubly, and be no more than 0.1mm from starting point to end diameter, the decorative pattern machined is clear glossy.Cutter can control pattern depth with scale.Need by external force.Processing work multiple clamping can not affect surface of the work.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the structural representation of knurling tool described in the utility model;
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As Fig. 1, a kind of knurling tool, comprises the substrate 1 of strip, and the top of substrate 1 side is provided with cross connecting plate 2, and the top of substrate 1 opposite side is provided with the guided way 4 of arc.Engaging lug 21 is stretched out in the both sides of connecting plate 2, and the thickness of engaging lug 21 is less than the thickness of connecting plate 2 main body.
Two engaging lugs 21 are hinged with tool arm 3 respectively, tool arm 3 comprises the guide part 31 be positioned in the middle part of tool arm 3, be positioned at extension 32 and the connecting portion 33 of guide part 31 both sides, the termination of connecting portion 33 is provided with transverse concave groove 331, Snap joint ear 21 in transverse concave groove 331, jointed shaft 332 is through the left and right sides after transverse concave groove 331 and engaging lug 21, tool arm 3 being hinged on connecting plate 2.
The middle part of guide part 31 is provided with pilot hole 311, and guided way 4 passes from pilot hole 311, and two tool arms 3 can along guided way folding.
Locking column 312 is also provided with in the pilot hole 311 of guide part 31, locking column 312 has screw, stud 5 passes and is spirally connected with locking column 312 from the screw two tool arm 3 locking columns 312, two tool arms 3 are locked in fixed angle by stud 5, the end of stud 5 is provided with a handwheel 7, and turning a handwheel 7 can carry out the locking and unlocking by two tool arms 3.
The termination of tool arm 3 extension 32 is provided with groove 321, is hinged with knurling tool 6 in groove 321 by rotating shaft 322.
Man-hour is added to the shaft-like annular knurl that carries out of small diameter greater depth, bar is placed on the middle part of two tool arms 3, owing to processing under the clamping of two tool arms, rod member can not be single-phase stressed and bend, reaction force would not be produced to lathe simultaneously, avoid the destruction to lathe.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
