The utility model discloses a ring-cutting knife. The utility model comprises a positioning shaft and a cylindrical hollow cutting knife, wherein the cylindrical hollow cutting knife is sheathed in the positioning shaft through a centre hole of the back end face, the cylindrical hollow cutting knife can be rotated around the positioning shaft and can be moved upwards and downwards along the positioning shaft, an air hole is arranged on the back end face of the cylindrical hollow cutting knife, a sawtooth-shaped knife edge is arranged on the front end of cylindrical hollow cutting knife, and an edge boss which is convenient for spanner clamping is arranged on a knife body. The utility model has the advantages of simple structure, manual operation, application of present maintenance, no sanding of cutting holes, short maintenance time, high work efficiency, easy chip removal and feeding and broad application, and is especially suitable for the maintenance of pit gears.
Description
One. technical field: the utility model relates to a kind of sealing ring drilling equipment, particularly relates to a kind of ring-cutting knife.
Two. background technology: well-known, sealing ring is used very extensive in various running devices, play crucial effect, it is generally made by professional production producer, but, many uses producer usually runs into the not really suitable situation of sealing ring in maintenance process, at this moment need existing sealing ring is repaired, perhaps process new sealing ring again, this need hole or shear, and Chinese patent (Granted publication number be CN2422079Y, the patent No. is 00234876.4) discloses a kind of " Hollow trepanning drilling machine ", it comprises drillstock, cutter hub, chip leading plate has mohs tapered bore and chain of command on the drillstock; Cutter hub is a tubular, and has a blade groove vertically, is blade on the side tool body of blade groove, and chip leading plate is housed in the cutter hub, can process the bigger aperture of diameter, and the material heart after drilling through can continue to use, and improves the utilization rate of material, cuts the waste.But this drill bit need with the supporting use of drilling machine, can not be applied to maintenance sites at any time, increase the time of maintenance, influence maintenance efficiency, and this drill bit is used in metal boring, do not have the drilling and reaming of the sealing ring of special use.
Three. the utility model content:
The purpose of this utility model: overcome the defective of prior art, provide a kind of simple in structure, cost is lower, be applicable to the ring-cutting knife of on-the-spot sealing ring boring.
The technical solution of the utility model: a kind of ring-cutting knife, contain locating shaft and cylinder type hollow cutting knife, wherein said cylinder type hollow cutting knife is sleeved on the locating shaft by the centre bore of end face thereafter, and described cylinder type hollow cutting knife can rotate and can move up and down along locating shaft around locating shaft.
The rear end face of described cylinder type hollow cutting knife is provided with air-vent.
The front end of described cylinder type hollow cutting knife is a serrated edge, and the cutter hub of described cylinder type hollow cutting knife is provided with terrace with edge, is convenient to the spanner mounting board.
The upper end of described locating shaft is provided with horizontal handle, and its middle part is provided with spacing ring.
Be the axis hole matched in clearance between the centre bore of described cylinder type hollow cutting knife rear end face and the locating shaft, be respectively equipped with the screw thread that is complementary on the centre bore of perhaps described cylinder type hollow cutting knife rear end face and the locating shaft, the two connects by threaded engagement.
The beneficial effects of the utility model:
1. the utility model is simple in structure, easy to use, carries out manually-operated, can be applied to maintenance sites, is convenient to maintenance of equipment, shortens maintenance time, increases work efficiency.
2. the utility model is simple to operate, and feeding easily, and locating shaft is inserted the cushion rubber endoporus, with the cutter hub of the hollow cutting knife of hand slewing circle cylindricality, cutter hub moves down by locating shaft, cuts, can be whittled into the neat face of cylinder to sealing ring inside, need not polishing, very convenient.
3. easy chip removal of the utility model and feeding, the rear end face of cylinder type hollow cutting knife is provided with air-vent, and the air drag when eliminating the hollow knife cutting like this helps cutting; Adopt serrated edge in addition, its smear metal enters in the hollow cavity easily, improves cutting speed and fineness.
4. cutter hub of the present utility model is provided with terrace with edge, is convenient to the spanner mounting board, and the upper end of locating shaft is provided with horizontal handle, is convenient to operate locating shaft.
5. the utility model scope of application is wide, particularly is applicable to the maintenance of pit gear, promotes easily, has good social and economic benefit.
Four. description of drawings:
Fig. 1 is one of structural representation of ring-cutting knife
Fig. 2 is the left view of ring-cutting knife shown in Figure 1
Fig. 3 be ring-cutting knife structural representation two
Five. the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the cylinder type hollow cutting knife 4 of ring-cutting knife is sleeved on the locating shaft 1, and is provided with the screw thread that is complementary between the centre bore of end face and the locating shaft 1 thereafter, and cylinder type hollow cutting knife 4 can be moved up and down along locating shaft 1.The rear end face of cylinder type hollow cutting knife 4 is provided with air-vent 5, and its front end is a serrated edge 2, and the cutter hub of cylinder type hollow cutting knife is provided with the terrace with edge (not shown), is convenient to the spanner mounting board.In addition, the upper end of locating shaft 1 is provided with horizontal handle 6, is convenient to operate locating shaft 1, and its middle part is provided with spacing ring 3, and with the cutting depth of restriction cutter hub, spacing ring 3 can adopt the form of single nut, also can adopt the form of double nut.As required, laterally handle 6 can be connected by the upper end of screw thread with locating shaft 1, also can connect by the mode of welding.
During use, locating shaft 1 is inserted the cushion rubber endoporus, with the cutter hub of the hollow cutting knife 4 of hand slewing circle cylindricality, cutter hub moves down by the screw thread on the locating shaft 1, cuts, and can be whittled into the neat face of cylinder to sealing ring inside, need not polishing, and is very convenient.
Embodiment two: referring to Fig. 3, numbering is identical with embodiment one among the figure, and the meaning of representative is identical, and something in common does not repeat, and difference is: for the axis hole matched in clearance, do not have screw thread between the centre bore of cylinder type hollow cutting knife 4 rear end faces and the locating shaft 1.
Change the version of hollow cutting knife, the version that changes locating shaft and the annexation that changes between the two and can form a plurality of embodiment, be common excursion of the present utility model, do not describe in detail one by one at this.
