Description
Technical field
The present invention relates to mechanical field, more particularly to a kind of lathe.
Background technology
Workpiece needs to carry out cutting process to workpiece in process, such as on a production line enters the workpiece of continuous output
Row cutting, in actual mechanical process, cutter its blade during Long-Time Service can become not sharp or deformation, in cutting workpiece
When can cause otch out-of-flatness and the slow problem of cutting speed of workpiece；In addition the cutter changing time is longer, it usually needs 5 minutes
Left and right, it is therefore desirable to turn off equipment and whole production line to change, so as to reduce work-piece throughput, additionally due to work during cutting
The temperature requirement of part is higher, and product once cools down and is just unfavorable for cutting.
The content of the invention
The invention is intended to provide a kind of lathe of quick-replaceable cutter, to solve prior art in cutter need to stop production and change
Problem.
To reach above-mentioned purpose, the base case of the present invention is as follows：The lathe of quick-replaceable cutter, including frame, including
Knife unit, driver element and polishing unit, the knife unit includes rack-mounted power transmission shaft, the power transmission shaft
One end is provided with two cutting tools, and two cutting tools are mutually perpendicular to, and the other end of the power transmission shaft is coaxially connected with driven
Gear；The driver element includes motor and the first cylinder, and first cylinder is fixedly connected in frame, and the first cylinder
Output end and motor connection, be coaxially connected with the output shaft of the motor can with the driving gear of driven gear engaged transmission,
And the output shaft middle part of motor is socketed with bearing, and on the bearing support is hinged with, the support is fixed in frame, and the polishing is single
Unit includes the second cylinder and control slide block, and second cylinder is fixed in frame, and second cylinder is provided with touch switch,
Vertically-mounted on the output shaft of the second cylinder to have two polishing parts, two polishing parts are located at respectively cutting tool rotating path
Both sides, for cutting tool of polishing, the control slide block is vertically slidably connected in frame, and when the second cylinder operation,
Control slide block two ends offset respectively with the switch of cutting tool and the second cylinder.
The principle and advantage of this programme be：When polishing cutting tool is needed, start the first cylinder, the first cylinder is promoted
Motor is moved down by fulcrum of support, when driving gear and driven gear are engaged, will be connected to the lock pin on power transmission shaft
Take out, make power transmission shaft free to rotate.After driven gear rotates 90 ° with driving gear, the first cylinder pulls motor to make actively
Gear departs from driven gear, and lock pin is inserted into the through hole of power transmission shaft and power transmission shaft is fixed.Now need that what is polished to cut
Cutter tool rotation to horizontal level, and between two polishing parts, while needing the cutting tool of polishing moving upwards
During, drive control slide block to move up and offset with the first touch switch of the second cylinder, just start the second cylinder
Work, promotes polishing part on the blade of cutting tool to return mill.So just complete the online replacing of cutting tool and beat
Grinder is made.
The advantage of this programme is：This programme can complete the replacing of cutting tool in production work, solve traditional skill
Art needs pass hull closure to stop production changing the problem of cutter；And speed is changed, each replacing construction is less than 0.5s；
Secondly when wherein a cutting tool carries out work piece cut process, another cutting tool that need to be polished also is polished in synchronization,
Improve operating efficiency；By the continuous replacing of two cutting tools, it is ensured that the cutting tool in cutting work is all the time
Sharp blade is kept, so as to improve cutting speed and cut quality.
Preferred version 1：Based on scheme improvement, the lock pin be irony structure, be additionally provided with electricity in the frame
Magnet, the electromagnet is relative with lock pin, and between the electromagnet and lock pin stage clip is connected with, and by above-mentioned setting, works as electricity
Magnet is powered and suction out the lock pin being inserted in transmission shaft through-hole with after magnetic, makes power transmission shaft free to rotate, when lock pin exists
It is inserted into through hole in the presence of stage clip, just realizes the locking to power transmission shaft.
Preferred version 2：Preferably 1 improvement, the flank of tooth of the driven gear is provided with two second points and touches to be opened
Close, second touch switch is connected electrically on electromagnet, and the center line of two second touch switch respectively with two
The center line of through hole is located at same straight line, by above-mentioned setting, because driving gear and driven gear are not nibbled under normal circumstances
Resultant motion, when needing to change cutting tool, driving gear is moved down and engaged with driven gear, using driving gear and the
The electromagnet of shake-up in a flash of two touch switch contact is powered with magnetic, the lock pin being connected on power transmission shaft is taken out, with master
The rotation of moving gear, the second touch switch resets, and magnetic force disappears after electromagnet power-off, and lock pin is in free state until with
When one through hole is relative, lock pin is just extend into through hole in the presence of stage clip.
Preferred version 3：Based on scheme or preferred version 2 improvement, the cutting tool is detachably connected on transmission
On axle, when wherein a cutting tool occurs in that the problem that cannot be repaired, the cutting tool can be disassembled changed with
It is cost-effective.
