Description
Technical field
The utility model belongs to the process tool technical field, relates to a kind of rose reamer.
Background technology
Rose reamer, as an important component part in cutter for machining, is mainly used in the orifice chamfer processing in hole.Existing rose reamer comprises cutter head and be fixedly installed on the blade on cutter head, and blade is fastened on it on cutter head by two bolts.Because the size of blade is less, cause the distance between two bolts little, when screwing, inconvenient operation, the wrench operated of twisting bolt is restricted, and causes bolt to be twisted not tight, and structural stability is poor, add the man-hour blade easily loosening, affect machining accuracy, even can cause security incident.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of good stability, has mounted and dismounted rose reamer easily.
The purpose of this utility model can realize by following technical proposal:
This rose reamer, comprise knife bar and the cutter head of being located at the knife bar front end, on described cutter head, have some even settings for the mounting groove of blade is installed, described blade is fixed in this mounting groove by fastening structure, it is characterized in that, in described mounting groove, have with blade on the installing hole one that is oppositely arranged of the first installing hole and with blade on the installing hole two that is oppositely arranged of the second installing hole, described installing hole one and installing hole two are obliquely installed, described installing hole one is screwed hole.
In above-mentioned rose reamer, described fastening structure comprises the pressing plate of being located at the blade outside, the downside of described pressing plate has the joint pin stretched in installing hole two, also be provided with the installing hole three be oppositely arranged with above-mentioned installing hole one on described pressing plate, be equipped with the bolt be threaded with above-mentioned installing hole one in described installing hole three, described tilt bolt setting and its head abuts are on pressing plate.
When blade is installed, at first by the blade security protection in mounting groove, the first installing hole of blade and installing hole one are oppositely arranged, the setting relative to installing hole two of the second installing hole; Then pressing plate is put into to blade top, joint pin stretches in installing hole two, then bolt is inserted in installing hole one, reaches the purpose that blade is fixing after screwing.
In above-mentioned rose reamer, described mounting groove is two.
Compared with prior art, this rose reamer has following advantage:
Only need to turn a bolt during operation can be fixed to blade in mounting groove, and reasonable in design is simple to operation, its good stability after fixing, and the blade difficult drop-off, guaranteed the machining accuracy of blade, security is good.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Fig. 2 is the structural representation of the fastening structure that provides of the utility model.
Fig. 3 is the structural representation of the blade that provides of the utility model.
In figure, 1, knife bar; 2, cutter head; 3, mounting groove; 4, blade; 41, the first installing hole; 42, the second installing hole; 5, pressing plate; 6, joint pin; 7, bolt.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Rose reamer as shown in Figure 1, comprise knife bar 1 and the cutter head 2 of being located at knife bar 1 front end, has the mounting groove 3 for blade 4 is installed of some even settings on cutter head 2, in the present embodiment, as shown in Figure 1, the quantity of this mounting groove 3 is two, and is symmetrical arranged along the axis of cutter head 2.Blade 4 as shown in Figure 3 is fixed in this mounting groove 3 by a fastening structure.Wherein, in mounting groove 3, have with blade 4 on the installing hole one that is oppositely arranged of the first installing hole 41 and with blade 4 on the installing hole two that is oppositely arranged of the second installing hole 42, installing hole one and installing hole two are obliquely installed, installing hole one is screwed hole.
As shown in Figure 2, fastening structure comprises the pressing plate 5 of being located at blade 4 outsides, the downside of pressing plate 5 has the joint pin 6 stretched in installing hole two, also be provided with the installing hole three be oppositely arranged with installing hole one on pressing plate 5, be equipped with the bolt 7 be threaded with above-mentioned installing hole one in installing hole three, bolt 7 be obliquely installed and its head abuts on pressing plate 5.
When blade 4 is installed, at first blade 4 security protections are arrived in mounting groove 3, the first installing hole 41 of blade 4 is oppositely arranged, the setting relative to installing hole two of the second installing hole 42 with installing hole one; Then pressing plate 5 is put into to blade 4 tops, joint pin 6 stretches in installing hole two, then bolt 7 is inserted in installing hole one, reaches the purpose that blade 4 is fixing after screwing.
This rose reamer only need to turn a bolt 7 in when operation and blade 4 can be fixed in mounting groove 3, and reasonable in design is simple to operation, its good stability after fixing, and blade 4 difficult drop-offs, guaranteed the machining accuracy of blade 4, security is good.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
