Description
Technical field
The utility model relates to a kind of cutters, more specifically, it relates to a kind of positive and negative rose reamer.
Background technique
In the processing of part, it is often necessary to which the both ends of device to hole carry out positive chamfering and instead angle, so that hole be made to meet design
Standard.
Currently, common method is the proper chamfer machining first passed through on the outside of positive chamfering tool progress hole, process just
After chamfering, worker changes positive chamfering tool into anti-chamfering tool, is then carried out by one end on the inside of anti-chamfering tool device to hole anti-
Chamfer machining.
But when the part of worker's processing is more, in whole process, worker needs frequently to carry out more cutter
It changes, the replacement of cutter needs the time, so that entire part process velocity be made to reduce；And between the fixture and part of holding parts
Gap it is again smaller, when cutter touches fixture, fixture and cutter is easy to cause to damage, worker need to cutter and
Fixture is replaced, so as to cause production efficiency reduction.
Utility model content
In view of the deficienciess of the prior art, having the utility model lies in that providing a kind of positive and negative rose reamer and improving production
The effect of efficiency.
To achieve the above object, the utility model provides following technical solution: a kind of positive and negative rose reamer, including positive chamfering
Knife is equipped with anti-rose reamer in the positive rose reamer, and the anti-rose reamer is slidably connected in the positive rose reamer, described just to fall
The limiting buffer component for limiting the anti-rose reamer moving distance is provided between angle knife and the anti-rose reamer.
By using above-mentioned technical proposal, when worker is when carrying out part processing, worker passes through positive rose reamer device to hole outside
One end carry out positive chamfering operation, after the operation of positive chamfering, worker drives anti-rose reamer mobile towards one end on the inside of hole, leads to
It crosses anti-rose reamer and carries out instead angle operation, limiting buffer component is defined the moving distance of anti-rose reamer at this time, so that instead
Rose reamer is able to carry out preferable instead angle and operates, and worker can carry out two operations by a cutter, without to cutter into
Row replacement, to improve production efficiency.
The utility model is further arranged to: the positive rose reamer includes mounting portion, is fixedly connected on the mounting portion one
The positive corner portion at end is fixedly connected on the extension of the mounting portion other end, offers the first mounting hole, institute in the positive corner portion
It states and offers the second mounting hole on mounting portion, third mounting hole, first mounting hole, the second peace are offered on the extension
Dress hole and third mounting hole interconnect, the inner wall of the anti-rose reamer simultaneously with first mounting hole, the second mounting hole, the
The inner wall of three mounting holes contradicts.
By using above-mentioned technical proposal, positive corner portion carries out positive chamfering operation to workpiece, mounting portion to positive corner portion into
Row is fixed, and extension enables positive corner portion is more stable to be mounted in equipment, and anti-rose reamer is in the first mounting hole, the second peace
Sliding in hole and third mounting hole is filled, while anti-rose reamer is also limited by limiting buffer component, so that worker can be compared with
Easily part is processed.
The utility model is further arranged to: the anti-rose reamer include be slidably connected at it is anti-in first mounting hole
Corner portion is slidably connected at the fixed part being fixedly connected in second mounting hole and with instead corner, is slidably connected at third
The limiting section being fixedly connected in mounting hole and with fixed part.
By using above-mentioned technical proposal, operated instead corner carries out instead angle to workpiece, fixed part to instead corner into
Row is fixed, and limiting section limits the position of fixed part, makes anti-rose reamer is relatively stable to be threaded through in positive rose reamer, however corner exists
Deviation is less prone to when processing.
The utility model is further arranged to: the internal diameter of first mounting hole is less than the internal diameter of second mounting hole,
The inner wall of the one end of the fixed part far from limiting section and second mounting hole contradicts.
By using above-mentioned technical proposal, the internal diameter of the first mounting hole and the second mounting hole is had differences, so that fixed part
Position limited, so that the position in instead corner be made to be limited, keep the processing result in instead corner more accurate.
The utility model is further arranged to: the limiting buffer component includes the fixation being fixedly connected on extension
Seat, the slip hole being provided on fixed part, is threaded through the elastic component that both ends are fixedly connected with the limiting section and fixing seat respectively
The spacer pin that in the slip hole and both ends are fixedly connected with the mounting portion, spacer pin are slidably connected with slip hole.
By using above-mentioned technical proposal, when instead corner touches the fixture of holding parts, due to limiting section and admittedly
Determine between portion that there are elastic components, instead corner can move at this time, to reduce instead corner and the impaired probability of fixture；When
Instead when corner is far from fixture, instead corner resets under the action of the elastic member, it can proceed with instead angle operation at this time；Limit
Pin and slip hole rotate fixed part can not while sliding, so that instead corner is able to carry out instead angle behaviour
Make, in the case where ensuring to operate progress, so that instead corner and fixture be not easily damaged.
The utility model is further arranged to: holding tank is offered on the limiting section, the elastic component is threaded through described
In holding tank, the inner wall of the side of the elastic component and the holding tank is contradicted.
By using above-mentioned technical proposal, holding tank is defined the position of elastic component, so that elastic component is in entire work
Make during be all not susceptible to be bent, enable instead corner reset in time, extend the service life of elastic component.
The utility model is further arranged to: being connected between the instead corner and the fixed part by the way that dormant bolt is fixed
It connects, the through hole passed through for the dormant bolt is offered on the mounting portion, the through hole internal screw thread is connected with blocking spiral shell
Bolt.
By using above-mentioned technical proposal, dormant bolt does not interfere the normal movement of fixed part, and through hole facilitates worker
Installation to dormant bolt, stop the setting of bolt so that in processing the iron filings that generate be not easily accessible mounting portion and fixed part it
Between, so that fixed part can normal movement.
The utility model is further arranged to: the two sides of the mounting portion offer limit hole, the both ends clamping of spacer pin
In limit hole, caging bolt, the end conflict of the caging bolt and spacer pin are threaded on the limit hole.
By using above-mentioned technical proposal, caging bolt is defined the position of spacer pin, is not easy spacer pin in height
Deviate from speed rotation, so that instead the moving range in corner is limited for a long time.
In conclusion the utility model has the following beneficial effects:
1, worker is made to exist by the way that positive rose reamer, anti-rose reamer and limiting buffer component, positive rose reamer and anti-rose reamer is arranged
Two processes can be carried out in once-through operation simultaneously, substantially reduce the process time of part, while limiting buffer component is to anti-
The moving distance of rose reamer is defined, and makes anti-rose reamer not easily damaged in the case where ensuring anti-rose reamer precision.
