Description
Technical field
The present invention relates to field of machining, more particularly, to a kind of awl being easily installed.
Background technique
In machining, it is often necessary to bore operation carried out to part to be processed, drilling can use rotary cutting or
The mode of rotary squeezing, leaves cylindrical cavity in parts to be processed.In the prior art according to the hell of different demands
Diameter needs to match different root diameters, and the size of rotor often uses fixed dimension, when boring work between different-diameter size
The awl of replacement respective model need to be carried out, working efficiency is low.Therefore, the present inventor is in the case where summarizing many years industry experience,
It has invented one kind and has not had to replacement awl, the awl structure of bigbore awl is mounted directly outside small-bore awl.
Summary of the invention
The present invention provides a kind of awl being easily installed, and to solve conventional borehole machine according to different boring aperture demands, needs
Different awls are replaced back and forth, the problem of low efficiency.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of adjustable awl of diameter, packet
Awl fixing seat is included, the awl fixing seat connects the first awl and adjusts awl, and first awl is outer with adjusting awl
Portion is equipped with cutting helical edges, and the adjusting awl is interior hollow round column structure, is equipped in the interior hollow round column structure and sets at screw thread
The cutting helical edges for setting the first awl of cooperation carry out the fixed strip of rotation installation.
Further, the adjusting awl top is equipped with several raised fixed blocks, and it is convex that the awl fixing seat is equipped with cooperation
Play the perforation conduit that fixed block screws.
Further, first awl top is equipped with the first cross through hole, and it is laterally logical that the adjusting awl is equipped with second
Hole, the awl fixing seat are equipped with the third cross through hole and locking spiral shell of the first cross through hole of cooperation and the locking of the second cross through hole
Nail.
Further, U-shaped fixed strip is equipped with outside the awl fixing seat, the U-shaped fixed strip is equipped with aperture for solid
Determine lock screw.
Further, the adjusting awl top is equipped with twisting handle, and the twisting handle includes being clamped in adjusting awl
The fixed ring and handle of periphery.
Further, the diameter of the hollow structure is no less than the diameter of the first awl.
The beneficial effects of the present invention are:
Present invention improves over the structures of traditional awl, are coaxially disposed by multiple awls, and the awl of outer layer is socketed in
One item that is screwed is set by hollow structure, be screwed item and the upper one layer of awl of the adjusting awl of each socket are cut
The thread-like structure for cutting helical edges is cooperated, and be can choose and is tightened, and is tightened rear each awl and is consolidated by awl fixing seat
It is fixed, and it is equipped with through-hole on each awl and awl fixing piece, by being inserted into lock screw, to each brill to combine
Son is fixed, and avoids awl in actual use, after piercing in hole, needs to take out, it is often necessary to drilling machine into
When row rotates backward to extract awl, the awl of socket will not be rotationally disengaged because of thread matching structure.Reach convenient adjusting
Awl bore, it is easy for installation, improve processing efficiency.
Detailed description of the invention
Fig. 1 is a structural schematic diagram of the invention；
As shown in the figure: 1- awl fixing seat, the first awl of 2-, 3- adjust awl, 4-U type fixed strip, 11- and lock spiral shell
Nail, 31- twist handle, 32- protrusion fixed block, 33- fixed strip.
Specific embodiment
Technical solution in embodiment in order to enable those skilled in the art to better understand the present invention, and make of the invention real
The above objects, features, and advantages for applying example can be more obvious and easy to understand, with reference to the accompanying drawing to technical side in the embodiment of the present invention
Case is described in further detail.
As shown, a kind of awl being easily installed, including awl fixing seat 1, the awl fixing seat connection first are bored
Son 2 and adjusting awl 3, first awl and the outside for adjusting awl are equipped with cutting helical edges, and the adjusting awl is interior
Hollow round column structure, the diameter of hollow structure cut the diameter of helical edges not less than the first awl；It is set in the interior hollow round column structure
The cutting helical edges for having into screw thread setting the first awl of cooperation carry out the fixed strip 33 of rotation installation.The structure has abandoned traditional brill
The method that son needs to remove replacement major diameter awl, is fabricated to interior hollow round column structure for bigbore awl, by by screw thread cloth
The fixed strip set is arranged to cut the structure of helical edges cooperation, directly during installation, carries out internal awl as threaded rod
Installation is easy for installation, quick.
As a further improvement of the present invention, the adjusting awl top is equipped with several raised fixed blocks 32, the awl
Fixing seat is equipped with the perforation conduit that fitting projection fixed block screws.Perforation conduit on raised fixed block cooperation firm banking,
When adjusting awl and the first awl rundown process, raised fixed block is just caught in perforation conduit.
As a further improvement of the present invention, first awl top is equipped with the first cross through hole, the adjusting awl
Equipped with the second cross through hole, the awl fixing seat is equipped with the first cross through hole of cooperation and the third of the second cross through hole locking is horizontal
To through-hole and lock screw 11.The mechanism passes through through-hole and lock screw after raised fixed block is just caught in perforation conduit
Cooperation, allow adjust after awl and the first awl are tightened being fixed, when left and right different directions being avoided to rotate, adjust awl from cutting
It cuts in helical edges and produces.The mechanism corresponds to, in actual borehole work operations, after drilling machine is pierced in hole using awl, and needle
The non-metallic materials such as timber can be blocked awl, it is difficult to extract, operator rotates backward button often through on drilling machine
Rotate backward awl, allow awl to drill out drilling outer, at this point, by the fixation of lock screw, adjust awl would not because of
When screw thread rotates backward, it is swapped out outside the first awl.
As a further improvement of the present invention, U-shaped fixed strip 4, the U-shaped fixed strip are equipped with outside the awl fixing seat
Fixedly locked screw is used for equipped with aperture.When U-shaped fixed strip is used in the locking level installation of lock screw, makes locking level, lead to
Progress arc outside awl fixing seat is crossed to fix, which allows awl in rotation, the vibration to lock screw locking cap is reduced,
Play fixed function.
As a further improvement of the present invention, the adjusting awl top is equipped with twisting handle 31, the twisting handle packet
Include the fixed ring and handle for being clamped in and adjusting awl periphery.Twisting handle can be in order to adjust awl in installation and removal, more
It is convenient and laborsaving to add.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
