Description
Technical field
The present invention relates to a kind of cylindrical drill, be specifically related to a kind of adjustable fast automatic discharging cylindrical drill, belong to Machining Technology field.
Background technology
Cylindrical drill is widely used in machining reaming blanking process, service life of cylindrical drill, whether can accomplish not shut down automatically blanking fast, be to save processing cost, improve working (machining) efficiency, key factor.
Use common fixed cylindrical drill processing plate workpiece on common driller time, because fixed cylindrical drill cutting edge length can not be adjusted, so the clout overlapping can not exit automatically in cylindrical drill, need to shut down manually clout is taken out, working (machining) efficiency is low.
In addition, cylindrical drill cutting edge is through after reconditioning repeatedly, and cutting edge shortens, total length shortens, and causes overall cylindrical drill to reuse and destroys, and has caused unnecessary waste, has increased production cost.
Summary of the invention
For solving the deficiencies in the prior art, the cylindrical drill that the object of the present invention is to provide a kind of cutting edge adjustable in length, clout automatically to exit.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of adjustable fast automatic discharging cylindrical drill, comprise: taper shank cutterhead, the pilot bit being coaxially fixedly installed with aforementioned taper shank cutterhead, it is characterized in that, also comprise: be enclosed within aforementioned pilot bit and can be along the dish of pusher in axial sliding of aforementioned pilot bit, on aforementioned pusher dish, cover has back-moving spring, on the sidewall of pusher dish, be formed with stopper slot, on the sidewall of taper shank cutterhead, be provided with the stop screw coordinating with aforementioned stopper slot; On aforementioned taper shank cutterhead, be formed with blade standing groove, in blade standing groove, be provided with blade, the degree of depth of blade in blade standing groove can be adjusted.
Aforesaid adjustable fast automatic discharging cylindrical drill, is characterized in that, aforementioned blade is fixed in blade standing groove by trip bolt.
Aforesaid adjustable fast automatic discharging cylindrical drill, is characterized in that, the afterbody of aforementioned blade stretches out taper shank cutterhead.
Aforesaid adjustable fast automatic discharging cylindrical drill, is characterized in that, aforementioned taper shank cutterhead adopts 45
#steel is made.
Aforesaid adjustable fast automatic discharging cylindrical drill, is characterized in that, aforementioned pusher dish adopts 45
#steel is made.
Aforesaid adjustable fast automatic discharging cylindrical drill, is characterized in that, aforementioned blade is high-speed steel shaping blade.
Usefulness of the present invention is: safe, practical, simple to operate, convenient and swift; The length of blade on cylindrical drill is adjustable, and can carry out repetition sharpening, in the service life of having improved blade, has saved blade cost; Utilize pusher dish that clout is ejected automatically in cylindrical drill, saved process time, improved working (machining) efficiency; Be applicable to be arranged on all drilling machines and use, production efficiency is further enhanced.
Brief description of the drawings
Fig. 1 is the perspective view of a specific embodiment of adjustable fast automatic discharging cylindrical drill of the present invention;
Fig. 2 is the profile of the adjustable fast automatic discharging cylindrical drill in Fig. 1.
The implication of Reference numeral in figure: 1-taper shank cutterhead, 2-pilot bit, 3-trip bolt, 4-pusher dish, 5-back-moving spring, 6-stopper slot, 7-stop screw, 8-blade, 9-trip bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
See figures.1.and.2, adjustable fast automatic discharging cylindrical drill of the present invention comprises: taper shank cutterhead 1, blade 8, pilot bit 2 and pusher dish 4, and wherein, pilot bit 2 is coaxially fixedly installed with taper shank cutterhead 1, and the two realizes fastening by trip bolt 3, pusher dish 4 is enclosed within pilot bit 2, and can sliding axially along pilot bit 2, for guaranteeing that pusher dish 4 can not get off pilot bit 2 in landing, on the sidewall of pusher dish 4, be formed with stopper slot 6, on the sidewall of taper shank cutterhead 1, be provided with stop screw 7, the head of stop screw 7 stretches in stopper slot 6, the two engagement limits the distance that moves of pusher dish 4, thereby guarantee that pusher dish 4 can not get off pilot bit 2 in landing, in addition, on pusher dish 4, also cover has back-moving spring 5, back-moving spring 5 does vertically flexible slip for guaranteeing pusher dish 4 in pilot bit 2, on taper shank cutterhead 1, be formed with blade standing groove, blade 8 is arranged in blade standing groove, and the degree of depth of blade 8 in blade standing groove can be adjusted, blade 8 is preferably fixed in blade standing groove by trip bolt 9, because the length of blade on cylindrical drill is adjustable and can carry out repetition sharpening, so effectively improved the service life of blade, saved blade cost.
As the preferred scheme of one, the afterbody of blade 8 stretches out taper shank cutterhead 1, thus, not only can be directly acquainted with the residue length of blade 8, and facilitates adjustable blade 8 position in blade standing groove.
Taper shank cutterhead 1, pusher dish 4 preferably adopt 45
#steel is made, the preferred high-speed steel shaping blade of blade 8.
Adjustable fast automatic discharging cylindrical drill of the present invention, its assembling process is:
1, taper shank cutterhead 1 is installed on drill press spindle endoporus, the length of adjusting blade 8 makes the cutting edge of all blades 8 on same cutting plane, and rotation trip bolt 9 is fastened on blade 8 on taper shank cutterhead 1.
