The beneficial effects of the utility model are: owing to have employed three-jaw self-centering chuck, utilize it to feel relieved and the function do not offset, shorten the time that batch machining forges bolt, improve production efficiency, can realize the object that rapid processing forges bolt-center hole; Adopt bracing or strutting arrangement to support three-jaw self-centering chuck, further increase the precision of bolt centre bore when processing forges.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Position and numbering in figure: drilling machine 1, three-jaw self-centering chuck 2, bracing or strutting arrangement 3, bracket 11, gripping mechanism 12.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As shown in Figure 1, the utility model comprises drilling machine 1, three-jaw self-centering chuck 2 and Height Adjustable bracing or strutting arrangement 3, one end of described three-jaw self-centering chuck 2 is fixed by the bracket 11 on described drilling machine 1 and gripping mechanism 12, described bracing or strutting arrangement 3 is positioned at the side of described three-jaw self-centering chuck 2 lower end relative to described bracket 11, for supporting three-jaw self-centering chuck 2 other end, make three-jaw self-centering chuck 2 maintenance level.Three-jaw self-centering chuck 2 has self centering function, can ensure that bolt-center does not offset with the bolt that it fixedly forges in operation, shortens the time of looking for bolt-center point, can realize rapid batch and process the object forged.But generally by the bracket 11 on drilling machine 1 and gripping mechanism 12, one end of three-jaw self-centering chuck 2 can only be fixed, when such processing forges, three-jaw self-centering chuck 2 can be subject to an active force vertically downward, under this active force, three-jaw self-centering chuck 2 finally can offset, leave horizontal level, it is very necessary for therefore increasing bracing or strutting arrangement 3, and described bracing or strutting arrangement 3 can have different structures.
Specifically, described bracing or strutting arrangement 3 comprises two feets, and each feet comprises epimere and hypomere, and described epimere has screwed hole, and described hypomere outer wall has the screw thread matched with described epimere screwed hole, and described epimere three-jaw self-centering chuck 2 connects.In use, can hypomere precession be made by rotating hypomere or screw out described epimere, realize highly regulating.Certainly, also can be that described hypomere has screwed hole, described epimere outer wall has the screw thread matched with described epimere screwed hole.
Specifically, described bracing or strutting arrangement 3 comprises two feets, and each feet comprises epimere, linkage section and hypomere, and described linkage section has screwed hole, described epimere and described hypomere outer wall have the screw thread matched with described linkage section screwed hole, and described epimere three-jaw self-centering chuck 2 connects.During use, can realize highly regulating by the section of being rotatably connected and hypomere.
Specifically, described bracing or strutting arrangement 3 is a column, and comprise epimere and hypomere, described epimere has screwed hole, and described hypomere outer wall has the screw thread matched with described epimere screwed hole, and described epimere three-jaw self-centering chuck 2 connects.During use, can realize highly regulating by rotating hypomere.Certainly, also can be that described hypomere has screwed hole, described epimere outer wall has the screw thread matched with described epimere screwed hole.
Specifically, described bracing or strutting arrangement 3 is a column, and comprise epimere, linkage section and hypomere, described linkage section has screwed hole, described epimere and described hypomere outer wall have the screw thread matched with described linkage section screwed hole, and described epimere three-jaw self-centering chuck 2 connects.During use, can realize highly regulating by the section of being rotatably connected and hypomere.
Specifically, the bracing or strutting arrangement used in above-mentioned embodiment is welded on described three-jaw self-centering chuck 2.In addition, in order to enable the hypomere that uses in above-mentioned embodiment more stable be fixed on drilling machine 1, can at the base of described hypomere weld metal pad as bracing or strutting arrangement 3.
In practical operation, need to select suitable three-jaw self-centering chuck 2 according to bolt length, bolt specification, generally, below M60 length is the three-jaw self-centering chuck 2 that Ф 250 selected by the bolt of 60mm ~ 300mm.The three-jaw self-centering chuck 2 chosen is arranged on drilling machine bracket 11, the fixing and locking device 12 of one end drilling machine is fixed, in order to keep the safety in production, at three-jaw self-centering chuck 2 edge relative to the side welding bracing or strutting arrangement 3 of fixing and locking device 12, preferably have the bracing or strutting arrangement 3 of the feet of this structure of epimere, linkage section and hypomere, bracing or strutting arrangement 3 is two feets preferably; Linkage section has screwed hole, epimere and hypomere outer wall have the screw thread mated with screwed hole, carried out the height of adjusting supporting device by the section of being rotatably connected or hypomere, thus adjustment three-jaw self-centering chuck 2 is to horizontal level, ensures the fastening of scroll chuck eventually through supported at three point.As shown in Figure 1, the utility model, primarily of three-jaw self-centering chuck in figure 2 and bracing or strutting arrangement 3, defines a kind of special cylindrical bolt fast searching center of circle and the fixture of stable fixing processing by welding combination.
Concrete operation step is, first fixture processing being forged bolt-center hole regulates levelling and is fixed on drilling machine, with chuck handle, the three-jaw of three-jaw self-centering chuck 2 is separated, by the bolt of undressed centre bore from oppositely stretching in three-jaw below, drilling machine is locked after exceeding three-jaw self-centering chuck 2 plane 10 ~ 20mm in bolt blank top, with scriber in the alignment of bolt top, the little concave point of center is stamped with awl, the drill alignment arm center concave point of the radial drilling machine of center bit will be loaded onto, drilling machine is locked, start the centre bore processing first bolt, by that analogy, drilling machine locking is not unclamped always, till this batch of bolt-center hole machined is complete.
In sum, the utility model mainly make use of the non-wiping function of feeling relieved of three-jaw self-centering chuck 2, when manufacturing batch forges bolt, as long as after first bolt-center hole site is determined, this batch of bolt-center hole site generally can not change, add up according to job shop, every root set time is 30 seconds to one minute, with on lathe, make every root compared with the centre bore time used save five to seven minutes, therefore the utility model is the device that a kind of rapid processing forges bolt-center hole.
