Description
Technical field
The invention is related to a kind of tobacco equipment mechanical maintenance tool in use, more particularly to a kind of fast quick-detach YJ17 cigarette machine into
The tool of knife mandril bearing, the detachable maintaining for disassembly gasket type bearing pre-buried in tobacco leaf production enterprise cigarette machine feed mandril
Work.
Background technique
YJ17 cigarette machine bar cutter device cuts hookes-type cutterhead using double-pole is double, using compressed air push into
Knife, the delivering gear is compact to design, reliable operation.But cutterhead feed mandril upper bearing (metal) 607-2Z damage is found in ordinary maintenance
After be not easy to replace, maintainability is poor.
The utility model patent of Patent No. ZL201320002707.7 discloses one kind can be quick for YJ17 cigarette machine
The cutterhead feed mandril for dismantling bearing carries out YJ17 cigarette machine cutterhead feed mandril using the method for pre-buried disassembly gasket
It redesigns and improves.Groove is processed in feed mandril bearing blind hole, disassembly gasket is machined with matched boss.Feed
Mandril blind hole inner groovy can be process by milling machine, therefore the shape of groove and gasket boss is designed as ellipse.This
It improves under the premise of guaranteeing the original work requirements of mechanism and operating accuracy, improves the maintainability of mechanism, still, still deposit
In very big defect, be mainly manifested in: although 1, disassembly gasket and feed mandril are without relative rotation, feed mandril is mounted on top
Inside pole socket, between the two by a snap ring positioning, feed mandril can still rotate in tip-lever support, therefore pre- with screw precession
Feed mandril can follow screw to rotate together when burying gasket, influence to dismantle；2, feed mandril exposes tip-lever support 3mm, using energetically
Forced area is small when pincers clamp the part of protrusion, and it is unobvious to clamp restriction effect, while also needing to pad adhesive tape protection feed mandril
It is not pinched, restriction effect after adhesive tape is added to weaken, be unfavorable for maintenance work progress, so there are pre-buried disassembly gaskets for the prior art
Formula feed mandril bearing removal Comparision trouble, the problem for causing maintenance personal's working efficiency lower.
Summary of the invention
The invention discloses a kind of extracting tools of YJ17 cigarette machine feed mandril bearing, and structure is simple, easy to make, tear open

Structure, can be with visual space sizing grip length.
Preferably, middle part screw thread is left-hand thread, and the lower thread is right-hand thread；The setting of this group of hand of spiral, more accords with
Close the habit of most people.
Preferably, sleeve handle is welded on sleeve outer surface, and structure is simple, and fastness is good.
The configuration of the present invention is simple, the components comprising manufacture are few, easy to operate, solve existing method for dismounting in disassembly
The problems such as being easily damaged feed mandril and long bearing removal time improves the efficiency of disassembly cigarette machine feed mandril bearing, has
Effect reduces bearing removal difficulty and labor intensity, and will not damage and cause feed mandril physical deformation, so that feed
The replacement and maintenance of mandril inner bearing becomes to be simple and efficient.In the cigarette equipment of tobacco enterprise to pre-buried disassembly gasket type into
The dismounting and change of knife mandril bearing, maintenance, have the characteristics that efficient quick.A series of various sizes of pull rods and set can be made
Cylinder is applied widely to adapt to the bearing and gasket of different-diameter, greatly reduces labor intensity, improves maintenance efficiency.
Handle jacket can press feed mandril end face, and forced area is big, and restriction effect is obvious and protects without adhesive tape, will not damage
Feed mandril.

Specific embodiment
The present invention is understood and realized for the ease of persons skilled in the art, now in conjunction with drawings and the specific embodiments into one
Step describes the extracting tool of YJ17 cigarette machine feed mandril bearing of the present invention.
The extracting tool of YJ17 cigarette machine feed mandril bearing as shown in Figure 1, Figure 2, Figure 6 shows, comprising: handle 1, pull rod 2,
Sleeve 4, sleeve handle 3, wherein the top 2a of pull rod 2 is radially provided with handle hole 2d, and handle 1 passes through handle hole 2d and pull rod 2
Connection.
Middle part 2b, the lower part 2c of pull rod 2 are respectively equipped with screw thread, also, the direction in the direction of middle part screw thread and lower thread
On the contrary, middle part screw thread is left-hand thread, the lower thread is right-hand thread；As shown in Fig. 2, the diameter of 2b is greater than pull rod in the middle part of pull rod
