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, a kind of more doctor fixing devices of the present utility model, including two be coaxially disposed clamp dress
The synchronizing shaft 8 of two clamping devices is put and connects, synchronizing shaft transmits clamping force so that two clamping devices are simultaneously synchronous to be realized
Pinching action, multi-disc doctor 1 are fixed between two clamping devices and by annular array, and its both ends is respectively by two folders
Tight device clamps；
Clamping device includes the auger tooth that chuck 2, the 2n clamping jaw 3 on chuck, driving clamping jaw slide clamping on chuck
The clamping drive mechanism 4 that wheel 7, driving bevel gear wheel rotate, n are more than 1；
Clamping drive mechanism includes the bevel pinion 42 being meshed with bevel gear wheel and for rotating bevel pinion manually
Clamping lever 41, bevel gear wheel is fixedly connected with synchronizing shaft, and clamping lever is rotatably on the chuck, bevel pinion and auger
Gear is arranged in a mutually vertical manner；
The back side of bevel gear wheel is provided with flat thread 71；
As shown in figure 3, chuck is disc, provided with the inner chamber that one end is opening in it, bevel gear wheel and bevel pinion are equal
Located at the intracavitary, its other end end face is provided with 2n bars center line and passes through the chuck center of circle and the slideway 21 of uniform annular array；
As shown in figure 4, clamping jaw is included positioned at one end for clamping the chuck 32 of doctor, the driving head positioned at the other end
34 and the glissile segment 33 slided along slideway positioned at middle part, referring again to Fig. 4, chuck is provided with two clamping sides, adjacent two folder
A doctor parallel space 5 for being used to place and clamp doctor is formed between the clamping side of pawl (to be used to clamp its interior wiping
Two clamping sides of knife are always parallel to doctor), the end face of driving head and the back side of bevel gear wheel lean, and set thereon
There is the arcuate thread groove 35 mutually screwed with flat thread；
Annular is fixed with 2n claw on chuck, therefore can fix multi-disc doctor between two clamping devices, passes through synchronization
The Synchronous Transmission of axle, two clamping devices realize the clamping of doctor both sides simultaneously, when that need to clamp doctor, need to only rotate any
Clamping lever on the clamping device of side, bevel pinion is rotated by clamping lever, bevel gear wheel rotation is driven, due to auger
Gear is threadedly coupled with clamping jaw, and bevel gear wheel is converted into synchronous the putting down along chuck slideway to chuck hub of 2n clamping jaw
Move, all adjacent parallel clamping sides are constantly close to doctor, and doctor parallel space constantly reduces, until clamping wiping
Knife, conversely, can loose unloading doctor；Can annular array and fixation due to 2n claw of annular array on each chuck, therefore thereon
2n doctor, when the doctor in work occurs wearing or be abnormal, operating personnel can fix dress by rotating more doctors
Work doctor can efficiently be replaced temporarily by putting, and realization, which is not shut down, more to change jobs, and ensures printing machine job stability, improves work
Make efficiency, and the doctor charge and discharge operations of the fixing device are simple, efficiency high changed, when greatling save the maintenance of staff
Between.
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, the height of locating dowel is less than doctor thickness, prevents it from cutting down clamping force.
As shown in Figures 3 and 4, slideway is T-slot, and glissile segment is the work shape structure slided on insertion T-slot.
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.
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.
