Abstract
The utility model discloses a tool fixture assembly capable of adjusting the depth of a step drill. The cutter fixture assembly comprises a drill bit, a hollow hole dilating tool, a fixture and a lock nut, wherein, the hollow hole dilating tool is sleeved on the middle part of the drill bit and fixed together with the drill bit, a blade is arranged at the head of the hole dilating tool and outside thread is arranged at the tail part of the hole dilating tool; the fixture is sleeved on the tail part of the drill bit through a through hole on the fixture, a threaded counter bore is arranged at the head of the fixture and the fixture is thread-connected with the tail part of the hole dilating tool through the threaded counter bore; the lock nut is pushed against the end surface of the head of the fixture and thread-connected with the tail part of the hole dilating tool. The tool fixture assembly can reduce the manufacturing procedures of the counter bore, shorten the manufacturing time and improve the work efficiency.
Description
Technical field
The utility model relates to a kind of machine tools, relates in particular to a kind of boring machining tool.
Background technology
In the actual process operation of various borings, the drilling operation personnel often need to use the drill bit of different-diameter to bore counterbore when joining the brill counterbore, and boring a counterbore needs feed and withdrawing just can finish for three times.The employed cutter of boring processing at present has: moulding is bored and fixing stage is bored.The problem that above-mentioned two kinds of boring bar tools exist is: during the different counterbore of the radius size of processing on the same center of circle, process tool can't be adjusted the height of cutter according to the degree of depth of counterbore, the front and back blade of process tool, promptly process the blade of aperture and the blade of processing macropore, can not arrive the station of appointment simultaneously, therefore cause the operating efficiency of counterbore processing very low.
Summary of the invention
The purpose of this utility model provides a kind of tool holder assembly of adjusting the stage drilling depth, this assembly be used to process have the same center of circle, plural large and small counterbore that radius is different, in process, the degree of depth control of large and small counterbore can realize by adjust cutter before processing, make the processing blade of cutter arrive the appointment station simultaneously, adopt this tool holder assembly processing counterbore can reduce manufacturing procedure, shorten process time, increase work efficiency.
In order to realize the foregoing invention purpose, the utility model provides a kind of tool holder assembly of adjusting the stage drilling depth, and it comprises:
One drill bit;
The broad of one hollow is placed in described drill bit middle part, and fixedly installs with described drill bit, and described broad head is provided with blade, and afterbody is provided with external screw thread;
One anchor clamps which is provided with a through hole, and described anchor clamps are placed in the afterbody of described drill bit by through hole, and the head of described anchor clamps also is provided with a screw-threaded counterbore, and described anchor clamps are connected with the tailing screw flight of described broad by screw-threaded counterbore;
One locking nut holds out against the head end of described anchor clamps, and is connected with the tailing screw flight of described broad.
Preferably, the afterbody of described anchor clamps is a bullet, have some axial grooves on the described bullet, be close to described bullet along described anchor clamps axial direction and also be provided with an external screw thread, one hold-down nut is connected with the external screw thread of anchor clamps afterbody by the internal thread of its front end, and is connected by the bellmouth of its rear end and the bullet of anchor clamps afterbody.
In addition, the anchor clamps described in the utility model can also fixedly wait other modes to show the fixing and locking of self by pin, are not limited to said fixing nut, bullet and externally threaded this a kind of mode that cooperates.
The combinations thereof body by rolling clamp, can be adjusted the relative position of broad and anchor clamps in use, thereby regulates the height of cutter when holing, and when the cutter adjusting puts in place, screws locking nut broad is located.The screw thread design of anchor clamps tail end is used for when the drill bit tail end is connected rotary drive mechanism with conical design, and the locking of anchor clamps self and location prevent that anchor clamps from separating with drill bit.During different large and small two the concentric counterbores of processing radius, drill bit is implemented minor radius boring to workpiece, when the blade of broad touches surface of the work, just it is carried out the reaming cutting, thereby realizes the one-shot forming that counterbore is processed.
The utility model passes through to adopt above-mentioned design, the feasible counterbore that needed multiple working procedure just can machine originally, and one-shot forming greatly reduces process time, has improved production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is for adjusting the structural representation of the tool holder assembly of stage drilling depth in a kind of exemplary embodiments of the present utility model.
Fig. 2 is the split structure chart of Fig. 1.
Fig. 3 is the structural representation of broad in the utility model.
The specific embodiment
Should be appreciated that present embodiment only is a kind of exemplary embodiment of adjusting the tool holder assembly of stage drilling depth described in the utility model, not as restriction to the described technical scheme of present embodiment.
As depicted in figs. 1 and 2, this tool holder assembly comprises: spiral bit 1, and its middle part is with a broad 2, and the two achieves a fixed connection by pin-and-hole provided thereon and pin, and promptly when spiral bit 1 rotation, broad 2 also rotates synchronously.Anchor clamps 4 are placed in the afterbody of spiral bit 1 by its central through hole, its head is provided with screw-threaded counterbore simultaneously, and be threaded by the tail end of this screw-threaded counterbore with anchor clamps 4, can adjust the two relative position in the axial direction by anchor clamps 4 with the relative rotation of broad 2, after relative position is determined, locking nut 3 is connected with the external screw thread of broad 2 tail ends, is used for broad 2 location.The afterbody of anchor clamps 4 is a bullet, have some axial grooves on the bullet, make the tail end of these anchor clamps 4 have certain flexibility of tightening up to the axle center, the afterbody next-door neighbour bullet of anchor clamps 4 also is provided with an external screw thread, hold-down nut 5 is connected with the external screw thread of anchor clamps 4 afterbodys by the internal thread of its front end, and be connected by the bellmouth of its rear end and the bullet of anchor clamps afterbody, be used to tighten up the fit clearance of anchor clamps 4 and spiral bit 1, prevent that anchor clamps 4 separate with spiral bit 1 when this assembly vertical drilling under the effect of gravity.
As shown in Figure 3, these broad 2 heads are provided with the rotating blade that carries out reaming, and afterbody is provided with and is used for the external screw thread that is connected with anchor clamps 4.
During work, will adjust the broad 2 of relative position and the outside that anchor clamps 4 are enclosed within spiral bit 1, and by screwing locking nut 3 locking positionings.Drive spiral bit 1 by lathe, spiral bit 1 drives broad 2 rotations of fixedlying connected with it simultaneously, carries out big aperture cutting.In this course of work, hold-down nut 5 is supported on the lathe rotary body, can not move up, and plays the retaining effect.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
