Specific embodiment
Core of the invention is to provide a kind of nose end cutting apparatus, and application through the invention will be significantly improved for workpiece
Nose end carries out the convenience and efficiency of chamfering or fillet processing.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the first schematic diagram of structure of the invention；Fig. 2 is the second schematic diagram of structure of the invention.
According to as shown in the figure, nose end cutting apparatus includes operating stick 1, cutter 2 and positioning mechanism, and cutter 2 is installed on operation
It the working end of bar 1 and can rotate, cutter 2 connects with positioning mechanism, and to switch positioning states and free state, operating stick 1 is used
In the through-hole of insertion workpiece.In the operating condition, cutter 2 is located at axially vertical position and in positioning states, cutter 2
Two sides be equipped with the cutting edge 21 of default angle, edge in the port of through-hole can be cut.It is arranged through the above structure, is operating
In the state that bar 1 is in workpiece through-hole to be processed, turned to by cutter 2 with axially vertical position and in positioning shape
State, then the cutting edge 21 of 2 two sides of cutter just can realize machining for through-hole end radial direction border by rotation, here institute
The cutter 2 said with it is axially vertical, axially refer to the hole axle of workpiece through-hole, certainly, because operating stick 1 is embedded in through-hole, cutter 2 is also at
Perpendicular to the location status of operating stick 1.It just can be realized by the rotation of operating stick 1 as a result, and chamfering processed to through-hole port
Or fillet, during overall processing, without carrying out the positioning of workpiece, this to operate convenience and efficiency has all obtained significantly mentioning
It is high.
For positioning mechanism, by its structure setting enable to cutter 2 be in the free state that can be freely rotated and
In the positioning states positioned, positioning mechanism can carry out various structures setting, and in the present embodiment, positioning mechanism is specifically arranged
Including screw thread locating rod 31, handle 32 and compression end, screw thread locating rod 31 is set in the inner hole of operating stick 1, and with 1 spiral shell of operating stick
Line connection, compression end are set to the bottom end of screw thread locating rod 31, and handle 32 is set to the top of screw thread locating rod 31, is positioned by screw thread
Bar 31 realizes offseting or separating for compression end and cutter 2 along the longitudinal movement of operating stick 1, with switch the positioning states of cutter 2 with
Free state.
Application for positioning mechanism, it includes the locknut for being mounted on screw thread locating rod 31 that positioning mechanism, which can also be arranged,
33, it is offseted by locknut 33 and the end of operating stick 1, realizes the positioning of screw thread locating rod 31, needing to rotate spiral shell as a result,
In the case where line locating rod 31, locknut 33 is unclamped, the rotation for carrying out screw thread locating rod 31 passes through after rotation
Locknut 33 is subjected to locking, avoids the unordered rotation of screw thread locating rod 31, which further improves operation convenience.
On the basis of above-described embodiment, setting nose end cutting apparatus further includes eccentricity control bar 41 and is installed on eccentricity control
The oscillating rod 42 of 41 bottom end of bar, eccentricity control bar 41 is in the inner hole of screw thread locating rod 31 and eccentricity control bar 41 is arranged
Top externally protrudes out in screw thread locating rod 31, and oscillating rod 42 and cutter 2 are hinged, as a result, by controlling the movement of eccentricity control bar 41, this
In movement refer to the longitudinal movement of eccentricity control bar 41, then cutter 2 can be rotated synchronously with oscillating rod 42.In the present embodiment,
By the way that the structure of eccentricity control bar 41 and oscillating rod 42 is arranged, so that the rotation operation for cutter 2 can be more convenient, avoid
The operation for needing to stir 2 turned position of cutter by hand, especially for irregular part, when the position of through-hole port to be processed is not easy
In the state of carrying out stirring cutter by hand, then tension and compression are carried out by the top of the eccentricity control bar 41 to another end position of through-hole
Operation just can be realized the turned position switching to the cutter 2 of another end position.Among these, be preferably set up by oscillating rod 42 with
One end that eccentricity control bar 41 carries out hingedly so, it is possible to realize oscillating rod 42 is with 41 axial translation of eccentricity control bar, the other end
It can rotate and move with cutter 2, this is equivalent to the application of the piston crank mechanism principle in engine；Certainly, it is cutting with scissors
Other than binding structure, oscillating rod 42 can also be set and be flexibly connected with eccentricity control bar 41, realize the swing of oscillating rod 42.
On the basis of above-described embodiment, it can also be arranged between the top of eccentricity control bar 41 and handle 32 and reset is set
Spring 43 is acted on by the pressure of reset spring 43, after eccentricity control bar 41 operates mobile, the tension and compression of reset spring 43
Elastic force caused by deformation will drive 41 homing of eccentricity control bar, i.e. reset eccentricity control bar 41 and screw thread locating rod 31
Lengthwise position.Which further improves operation convenience.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
