Description

The automatic boring tool holder of end face

Technical field:

The utility model relates to machine tool accessories, and particularly a kind of radially end face in feed processing work hole that is used for automatically is particularly useful for the automatic boring tool holder of end face that big-and-middle-sized radial drilling machine such as Z3050, Z3080, Z30100 is processed the groove on end face and the end face.

Background technology:

At present, utilizing rocking arm Zuan Chuan Huo plane is to adopt molding cutter one or many (artificial mobile tool position) to become machined surface Bu Jin Huo not go out the plane of broad Gong spare Biao Mian Huo, and lathe effort, damage cutter easily, efficient is lower, and is difficult to obtain desirable flatness and surface roughness, moreover fluted again workpiece is impossible Yong Huo Dao Huo on low inside and high outside.

Summary of the invention:

Goal of the invention of the present utility model is intended to improve the described deficiency of background technology, and a kind of radial drilling machine function that can make full use of is provided, and saving operation, to raise the efficiency, and has power collection and the automatic boring tool holder of the simple end face of the kind of drive.

The technical scheme that realizes the foregoing invention purpose is: this automatic boring tool holder comprises with the affixed transition of Machine Tool Main Drive axle and connects handle, is connected the tool-post structure that this transition meets pommel portion by thread connecting mode, this tool-post structure bottom is provided with the dovetail groove of horizontal cross, feeding slide with dovetail guide is slidingly mounted on this tool-post structure by this dovetail groove, and the adjustable cutter head in position is equipped with by cutter head jackscrew and cutter trousers jackscrew in this feeding slide below; The worm screw of along its longitudinal center's line position the extensible bar being housed in the described tool-post structure is equipped with the worm gear with this worm engaging along the horizontal cross position, the axle head that this worm-wheel shaft extends to the tool-post structure left side is equipped with driving gear and clutch respectively; Be provided with the horizontal cross internal thread in the described feeding slide, the driven gear that meshes with this driving gear is equipped with in its outer end of a screw mandrel that screws in this internal thread.When tool-post structure rotates with the lathe final drive shaft is whole, the worm screw of extension bar is motionless relatively, and when rotating, also produce rotation with tool-post structure with the worm gear of its engagement, the result of its rotation passes to screw mandrel with power by described driving gear and driven gear, driving the generation of feeding slide by this screw mandrel again moves horizontally, therefore the movement locus of cutter head shape in the shape of a spiral, helix pitch be millimeter grade, and then cutter head has been finished the work of boring end face automatically.

Automatic boring tool holder according to technique scheme enforcement, once adorn cutter, both can be easily the plane in the feed processing work end face radially automatically, also can be in conjunction with the axial feed of radial drilling machine, the domatic and groove in the automated machining of workpieces end face, and machined surface is big, precision is high, increase the function of existing radial drilling machine, made the operation on its Jie Sheng Huo plane, improved working (machining) efficiency, its power collection and the kind of drive are effectively simple especially, need not additionally increase power source.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the side-looking structural representation of Fig. 1.

The specific embodiment

Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.

The described automatic boring tool holder of this embodiment is connect parts such as handle 1, tool-post structure 2, driving gear 3, driven gear 4, clutch 5, screw mandrel 6, feeding slide 7, cutter head 8, worm screw 9, worm-wheel shaft 10, cutter head jackscrew 11, cutter trousers jackscrew 12, rolling bearing 13, worm gear 14, extension bar 15, chuck 16 and forms by transition.The cone that this transition connects handle 1 its top is that No. 5, standard (being adapted to the Z3050 radial drilling machine) or No. 6 (the large-scale radial drilling machine of Z3080-100) Mohs have tongue tail cone handle, can be directly affixed with the Machine Tool Main Drive axle, there is external screw thread its underpart, corresponding internal thread is arranged on the tool-post structure 2, and both pass through thread connecting mode.These tool-post structure 2 bottoms are provided with the dovetail groove 17 of horizontal cross, feeding slide 7 with dovetail guide 18 is slidingly mounted on the bottom of this tool-post structure 2 by this dovetail groove 17, the adjustable cutter head in position 8 is equipped with by cutter head jackscrew 11 and cutter trousers jackscrew 12 in these feeding slide 7 belows, this cutter head 8 can be in any fixed-site of feeding slide 7, so that adjust the preceding aperture location of boring end face.These tool-post structure 2 inside are equipped with a worm screw 9 along its longitudinal center's line position by a pair of rolling bearing 13, and this worm screw 9 can be installed extension bar 15, and this extension bar 15 can be changed arbitrarily according to the degree of depth of workpiece hole; The worm gear 14 that meshes with this worm screw 9 is housed along the horizontal cross position, and this worm-wheel shaft 10 extends to tool-post structure 2 outer left side axle heads driving gear 3 and clutch 5 is housed respectively, and worm gear 14 can't be rotated by worm screw 9 self-lockings and design when this clutch 5 was advanced and retreat cutter for control.Be provided with the horizontal cross internal thread in this feeding slide 7, be installed in a screw mandrel 6 these internal threads of screw-in on the tool-post structure 2 and this screw-internal thread fit, the driven gear 4 with 3 engagements of this driving gear is equipped with in its outer end.Above-mentioned worm screw 9, worm gear 14, driving gear 3, driven gear 4, screw mandrel 6 mutual group become whole transmission of the present utility model and power acquisition system, thereby produce the power move radially and need not additionally increase power source.

When utilizing this automatic boring tool holder boring through hole end face, as long as clamp the extension bar 15 of worm screw 9 with arbitrary waste and old chuck 16, when lathe drives tool-post structure 2 rotations, worm gear 14 just can rotation in tool-post structure 2, and the rotation by worm-wheel shaft 10, driving gear 3, driven gear 4, promote feeding slide 7 and laterally move, finish the action of cutter head 8 radial cutting end faces.When needs cutter head 8 was return the original place, as long as clutch 5 extracted to revolve to be turn 90 degrees, the hand on the just available hand derotation driven gear 4 was turned round, and cutter head 8 is just return.

What is particularly worth mentioning is that, utilize these automatic boring tool holder processing two ends to have 90 of ring flange and spend heavy wall bend pipe end faces (supposing that this ring flange external diameter is that Φ 320, bend pipe external diameter are Φ 260), the advantage of more apparent this automatic boring tool holder.Its method is as follows: this knife rest is installed on the main shaft of Φ 75 radial drilling machines, can be finished the processing of two flange lines in the continuous processing, Φ 260 of Φ 260 end faces and the continuous processing of Φ 320 end faces as mentioned above very like a cork; Utilize the radial feeds of this knife rest revolution 0.08mm and the axial feeding of the every 0.093mm of drilling machine, auto-feed simultaneously can be finished the processing of Φ 260 to Φ 320 transitional slopes, and this function is that general lathe is difficult to accomplish.And after processing end face, need not unload workpiece, and on the spot this knife rest on the drill press spindle is changed the drill bit of Φ 18, thereby got out the installing hole on the ring flange, be a frock multiple tracks technology, the height of its efficient is apparent.
