Abstract
The utility model relates to a dynamic cutter head which comprises a cutter body, an outer sheath pipe, an inner cutter core, and inner cutter seat, and outer sheath seat, a restoring sleeve, a restoring spring and a connecting sleeve, wherein the inner of the outer sheath seat is provided with a globe joint of which the front end is provided with a globe joint head which is matched with the inner cutter seat and the back end face of the globe joint is provided with a supporting spring which is matched with the globe joint. The utility model has the advantages of reasonable structural design, small friction between cutter pipes, low noise and less frictional heat build up and the utility model can enable mechanical waves generated during work to obtain buffering and release.
Description
Technical field
This utility model relates to a kind of power-driven cutter head, belongs to medical instruments field.
Background technology
The available dynamic cutter head, form by cutter hub, epitheca pipe, interior cutter core, interior tool rest, epitheca seat, reseting sleeve, back-moving spring, adapter sleeve, wherein, cutter hub be divided into cutter head and inner core be arranged in the front end of cutter core, the outside of interior cutter core is with the epitheca pipe, in epitheca pipe clamp epitheca seat and the adapter sleeve, the bottom of adapter sleeve is provided with reseting sleeve, this power-driven cutter head is in work, can rub between interior cutter core, interior tool rest epitheca seat, reseting sleeve and the adapter sleeve, produce heat, make the cutter heating, but also have noise.
Summary of the invention
Technical problem to be solved in the utility model provides the power-driven cutter head that friction is little between a kind of reasonable in design, the cutter pipe, noise is low, frictional heat is few.
It is this power-driven cutter head that this utility model solves the problems of the technologies described above the technical scheme that is adopted, form by cutter hub, epitheca pipe, interior cutter core, interior tool rest, epitheca seat, reseting sleeve, back-moving spring, adapter sleeve, its construction features is: be provided with ball-joint in the epitheca seat, the front end of ball-joint is provided with the ball-joint head, ball-joint head and interior tool rest are complementary, rear end face is equipped with support spring, and support spring and ball-joint are complementary.
Cutter hub described in the utility model is made up of interior cutter core and cutter head two parts, and interior cutter core and cutter head are split type.
This utility model is compared with prior art and is had the following advantages and effect: 1, owing to increased ball-joint and ball-joint head on the epitheca pipe, increased power-driven cutter head stability at work and alleviated concussion; 2, owing to increased support spring, make the mechanical energy that produces in the work form vibration wave and discharge to the periphery through spring, produce heat energy and infrasonic wave thereby reduce, reduced heating and noise.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with embodiment this utility model is described in further detail, following examples are to explanation of the present utility model and this utility model is not limited to following examples.
Embodiment
As shown in Figure 1, present embodiment is by cutter hub 12, epitheca pipe 11, interior cutter core 5, interior tool rest 4, epitheca seat 7, ball-joint 8, support spring 9, reseting sleeve 2, back-moving spring 3, adapter sleeve 1 is formed, wherein, the front end of cutter hub 12 is provided with cutter head 6, the rear end is interior cutter core 5, cutter head 6 can be complementary with interior cutter core 5, and can dismantle, cutter hub 12 is wrapped with epitheca pipe 11, interior tool rest 4 is enclosed within the outside of epitheca pipe 11, the back of interior tool rest 4 links to each other with adapter sleeve 1, reseting sleeve 2 is arranged on the rear end of epitheca pipe 11 and interior cutter core 5, adapter sleeve 1 is connected reseting sleeve 2 with interior tool rest 4, in adapter sleeve 1, be provided with back-moving spring 3 between reseting sleeve 2 and the interior tool rest 4, back-moving spring 3 links to each other with interior tool rest 4 with reseting sleeve 2 respectively, the front end of interior tool rest 4 is arranged in the epitheca seat 7, be provided with ball-joint 8 in the epitheca seat 7, ball-joint head 4-1 and interior tool rest 4 on the ball-joint 8 are complementary, and the leading portion of ball-joint 8 is connected with the support spring that is arranged between epitheca seat 7 and the interior cutter core 5.
During work, ball-joint 8 and support spring 9 can form vibration wave, have absorbed and discharged the tangential force that causes owing to cutter head and power transmission shaft decentraction in the installation.Reduced the energy of noise when producing heat energy and work, effectively alleviate " hot cutter " phenomenon, support spring 9 and back-moving spring make cutter head can adjust center and automatic capturing operating position automatically when matching work, improved operating speed, stability and the service life of cutter head.
Cutter head 6 of the present utility model can change with interior cutter core 5 and also can be fixed together.
