Abstract
The utility model discloses a reamer used for processing a fixed bead hole of a fixed bead ring. The reamer is used for processing the fixed bead hole, which not only can ensure the accuracy of the aperture of the fixed bead hole of the fixed bead ring but also enhance the position degree of the fixed bead hole. The reamer comprises a knife body, wherein the front part of the knife body is provided with a guide part, the back part of the knife body is provided with a fixed part, and a cutting part is arranged on the knife body between the guide part and the fixed part; and the cutting part comprises a plurality of cutting edges.
Description
Technical field
The utility model relates to a kind of instrument of deciding Zhu Quan of processing, and relates in particular to a kind of reamer of deciding the hole of bead of deciding Zhu Quan that is used to process.
Background technology
The technology of deciding the hole of bead that Zhu Quan is decided in existing processing is the punching out one-shot forming, one-time formedly in process of production decide the hole of bead and have many defectives, as zone of fracture problems affect aperture instability, deciding position, hole of bead degree difference influences the conical surface of deciding the hole of bead that following process goes out and concentricity etc.In order to revise the above-mentioned one-time formed defective in the hole of bead of deciding, can go out to decide the hole of bead by the punch press punching out earlier, relend and help cut with scissors mould and the reamer hole of bead of deciding of making that liquidates and reprocess, to meet the demands.Wherein, the design of reamer is most important.
The utility model content
Technical problem to be solved in the utility model provides a kind of reamer of deciding the hole of bead of deciding Zhu Quan that is used to process, and uses this reamer processing to decide the hole of bead, not only can guarantee to decide the aperture precision of deciding the hole of bead of Zhu Quan, and can improve the position degree of deciding the hole of bead.
The utility model comprises cutter hub, in the front portion of described cutter hub targeting part is set, and the rear portion of cutter hub is provided with standing part, on the cutter hub between described targeting part and the standing part cutting tip is set; Above-mentioned cutting tip comprises several cutting edges.
Reamer in the utility model is connected on the drilling machine by standing part, can make cutting edge successfully enter Working position by targeting part, and cutting tip then is used for the hole of bead of deciding to be processed is processed.Utilize the reamer in the utility model to reprocess, not only can guarantee to decide the aperture precision of deciding the hole of bead of Zhu Quan, and can improve the position degree of deciding the hole of bead deciding the hole of bead.
Preferably, described cutting edge is six.
The design of cutting position has six cutting edges, so that improve process velocity and crudy.
Preferably, each cutting edge length is 50mm.
The cutting edge of 50mm length can carry out repeatedly reconditioning, to improve the service life of reamer, saves processing cost.
