Abstract
The invention relates to technical field of cutters, particularly to a counter bore forming cutter. The counter bore forming cutter comprises a shank and a head which are connected with each other. The counter bore forming cutter is characterized in that an inner groove is formed in the shank and used for accommodating a cylinder, the head comprises an upper segment and a lower segment arranged under the upper segment, the upper segment is connected with the bottom of the shank and internally provided with a thorough hole for accommodating the lower segment, the upper portion of the lower segment is connected with a piston rod of the cylinder in the shank, section diameter of the upper segment is larger than that of the lower segment, six upper cutting blades are provided on the upper segment, a debris discharging slot is formed between every two adjacent upper cutting blades, two lower spiral cutting blades are formed on the lower segment, and a spiral debris discharging slot is formed between the lower spiral cutting blades. By the use of the counter bore forming cutter, the counter bore can be formed at one time, and production efficiency is improved.
Description
Technical field
The present invention relates to cutting-tool engineering field, be specifically related to a kind of counterbore forming cutter.
Background technology
Need drilling counterbore during a lot of work pieces process, when processing counterbore, need the hole first processed below, then change to processing hole above, process time is long, and tool changing tool setting also needs the time, can not one-shot forming, loses time, is unfavorable for enhancing productivity.
Summary of the invention
For the problems referred to above, the invention provides the disposable processing counterbore of a kind of energy, the counterbore forming cutter of enhancing productivity.
Realize technical scheme of the present invention
Counterbore forming cutter, comprise handle of a knife and cutter head, handle of a knife is connected with cutter head, described handle of a knife inside is provided with the inside groove holding cylinder, cylinder is provided with in inside groove, described cutter head comprises cutter head and lower cutter head, upper cutter head is arranged on above lower cutter head, upper cutter head is connected with below handle of a knife, the through hole holding upper cutter head is offered in described upper cutter head, the top of lower cutter head is connected with the cylinder piston rod being arranged on handle of a knife inside, the diameter of section of described upper cutter head is larger than the diameter of section of lower cutter head, upper cutter head is provided with six upper cutting edges, chip area is provided with between described every two upper cutting edges, described lower cutter head is provided with cutting edge under two spirals, helical flute is provided with between lower cutting edge.
Spiral limit on described helical flute is provided with arc chip-breaker.
Described cylinder piston rod is threaded with above lower cutter head.
Under the accommodation that described upper cutter head is offered, the diameter of the through hole on cutter head top is greater than the diameter on lower cutter head top.
Adopt such scheme, because cutter head comprises upper cutter head and lower cutter head, the cross-sectional diameter of upper cutter head is larger than the cross-sectional diameter of lower cutter head, upper cutter head is provided with six upper cutting edges, lower cutter head is provided with cutting edge under two spirals, when processing counterbore, energy one-shot forming, processing hole above while the lower face of processing, due to lower cutter head top and the cylinder piston rod being arranged on handle of a knife inside, regulate the length of lower cutter head with cylinder, can according to specific requirement, regulate the length of lower cutter head, improve the usage range of counterbore milling cutter.
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
Wherein, 1 is handle of a knife, and 2 is cutter head, and 3 is upper cutter head, and 4 is lower cutter head, and 5 is through hole, and 6 is cylinder, and 7 is cylinder piston, and 8 is upper cutting edge, and 9 is lower cutting edge, and 10 is chip area, and 11 is helical flute, and 12 is chip-breaker, and 13 is inside groove.
Detailed description of the invention
As shown in the figure, counterbore forming cutter, comprise handle of a knife 1 and cutter head 2, handle of a knife 1 is connected with cutter head 2, described handle of a knife 1 inside is provided with the inside groove 13 holding cylinder 6, cylinder 6 is provided with in inside groove 13, cutter head 2 comprises cutter head 3 and lower cutter head 4, upper cutter head 3 is arranged on above lower cutter head 4, upper cutter head 3 is connected below with handle of a knife 1, the through hole 5 holding upper cutter head 3 is offered in upper cutter head 3, under the accommodation that upper cutter head 3 is offered, the diameter of the through hole 5 on cutter head 4 top is greater than the diameter on lower cutter head 4 top, be convenient to the length regulating lower cutter head 4, the top of lower cutter head 4 is connected with the cylinder piston rod 7 being arranged on handle of a knife 1 inside, cylinder piston rod 7 is threaded above with lower cutter head 4, be convenient to change lower cutter head 4, with unload lower cutter head 4 and repair, the length of lower cutter head 4 is regulated with cylinder 6, can according to specific requirement, regulate the length of lower cutter head 4, improve the usage range of counterbore milling cutter, the diameter of section of upper cutter head 3 is larger than the diameter of section of lower cutter head 4, upper cutter head 3 is provided with six upper cutting edges 8, lower cutter head 4 is provided with cutting edge 9 under two spirals, when processing counterbore, energy one-shot forming, processing hole above while the lower face of processing, save process time, improve working (machining) efficiency, chip area 10 is provided with between described every two upper cutting edges 8, helical flute 11 is provided with between lower cutting edge 9, spiral limit on helical flute 11 is provided with arc chip-breaker 12, improve the chip removal ability of cutter, prevent chip from piling up, affect the rough degree in surface of machined surface.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
