Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As Figure 1-4, it is of the present utility model it is a kind of do not shut down the device of quick-replaceable doctor, including be coaxially disposed
Two chucks 2, the 2n clamping jaws 3 that can be translated on chuck being arranged on two chucks are corresponded respectively, drive clamping jaw to put down
Two clamping drive mechanisms clamped are moved, the synchronizing shaft 1 of two clamping drive mechanisms is fixedly connected with and is arranged on synchronizing shaft
And two cutter-exchange mechanisms being axially movable, clamp the both ends of doctor 9 respectively by one-to-one 2n clamping jaw, can be in card
Clamping n piece doctors on disk, n are more than 1；
Referring again to Fig. 1, bevel gear wheel 7 that clamping drive mechanism includes being connected by flat thread 71 with clamping jaw, with it is big
The bevel pinion 4 that bevel gear is meshed and the clamping knob for rotating bevel pinion manually, bevel pinion and bevel gear wheel
It is arranged in a mutually vertical manner, the translation that the rotary motion of bevel pinion transmission is converted into clamping jaw by bevel gear wheel by flat thread clamps
Motion；
Cutter-exchange mechanism include be fixedly connected respectively with two chucks two disks 61, be separately positioned on two disk sides
And by spring two terminal pads 5 being connected with chuck and the tool changing handle 8 being installed on synchronizing shaft one end, leaned in terminal pad
The end face of nearly disk is provided with coil 51, and terminal pad is connected with synchronizing shaft by spline, and magnetic force is produced after coil electricity so that even
Connect disk and slide and bonding close to disk along synchronizing shaft and be integrally formed, spring guide groove is additionally provided with terminal pad with retaining spring,
After power-off, under the action of the spring, terminal pad and magnetic disc separation；
Fixed two-by-two by 2n clamping jaws between two chucks, n doctor can be clamped, what is passed through is provided with the big of flat thread
The effect of bevel gear, clamping knob can be converted into slip clamping movement of the clamping jaw on chuck, it is synchronous in synchronizing shaft
Under, synchronous realize clamps the clamping jaw at doctor both ends simultaneously, and therefore, the clamp operation of doctor is simple and convenient, greatlys save behaviour
Make the lay day of personnel；Under clamped condition, if the doctor in work occurs wearing or be abnormal, coil power can be cut through,
Produce magnetic force to attract each other with disk so that terminal pad overcomes elastic force close to chuck along spline, and is finally bonded to chuck
It is integrated, is rotated and can switched to new doctor by synchronizing shaft rotating chuck and be operated, therefore, change by tool changing handle
Knife operation, which need not can be shut down, is loaded and unloaded, and tool changing is convenient and swift, ensures the stability of printing work, in use for some time,
It is unified to change abrasion cutter, maintenance time can be greatlyd save.
Referring again to Fig. 2 and Fig. 3, as further design, chuck is disc, provided with one end is opening in it
Inner chamber, bevel gear wheel and bevel pinion be located at the intracavitary, and its other end end face passes through the chuck center of circle provided with n bars center line
And the slideway of the T-slot shape of uniform annular array；Referring again to Fig. 2 and Fig. 4, clamping jaw is included positioned at one end for clamping wiping
The chuck 32 of knife, the driving head 34 being connected with bevel gear wheel by flat thread positioned at the other end and positioned at middle part along cunning
The glissile segment 33 for the work shape structure that road slides, chuck are provided with two clamping sides, and forming one between the clamping side of adjacent two clamping jaw uses
(always put down for clamping two clamping sides of its interior doctor in the doctor parallel space 10 for placing and clamping doctor
Row is in doctor), the end face of driving head and the back side of bevel gear wheel lean, and which is provided with the arc mutually screwed with flat thread
Shape thread groove 35, when rotating bevel pinion, bevel gear wheel is driven and under synchronizing shaft synchronous effect while drives 2n folder
Pawl is synchronous along chuck slideway to the translation of chuck hub, and all adjacent parallel clamping sides are constantly close to doctor, wiping
Knife parallel space constantly reduces, until clamping doctor.
For axially position doctor, at the same prevent change abrasion doctor when, remaining wiping cutter position deflection even pine
It is de-, the locating dowel for positioning doctor is may be provided with any surface in two clamping sides for forming doctor parallel space
31, as shown in Figure 2 and Figure 4, the height of locating dowel is less than doctor thickness, prevents it from cutting down clamping force.
In order to preferably support synchronizing shaft, while prevent dust from influenceing the engagement of gear, be additionally provided with chuck for covering
The gland 6 of inner chamber, synchronizing shaft are rotatably connected through gland and with gland, and disk is fixed on the outside of gland.
In order to improve the reliability for rotating tool changing, gland outer ledge is additionally provided with the paw 62 of several annular arrays, connects
Be provided with disk with the close lateral edges of gland it is several be used to be installed with the indents 52 of paw, when clamping jaw clamps doctor, paw with
The position of indent is corresponding, and paw end is provided with chamfering, when terminal pad to gland constantly close to when, paw insertion indent in,
Under the occlusion of paw indent, produced relative rotation when can prevent to rotate between gland and terminal pad.
It the above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of the art
For member, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as the scope of protection of the utility model.
