Abstract
The utility model discloses a boring device for a turning lathe. The boring device comprises a forming cutter (6), wherein a fixing pin (7) is arranged in the middle of the forming cutter (6) and is hinged with a sliding tool rest (9); a sliding pin (11) is arranged on the tail part of the forming cutter (6) and is connected with a chute (10) on a cutter rod (1) in a sliding manner; a cutter bit is arranged at the front end of the forming cutter (6); the sliding tool rest (9) is connected with a cylinder on the cutter rod (1) in the sliding manner and is connected with the cutter rod (1) through a pull rod (3); and a spring (2) is sleeved on the pull rod (3). By the boring device, the technical problems that a common turning lathe cannot machine large-sized workpieces or workpiece inner holes and workpieces with high hole eccentricity are solved, and defects in the prior art are overcome. The boring device has the characteristics of simple structure, high machining efficiency, high machining quality and the like and is conveniently and reliably used.
Description
Technical field
the utility model relates to a kind of lathe and uses boring device, belongs to the Machining Technology field.
Background technology
utilize the method for lathe tool boring processing workpiece endoporus to use very extensively on lathe in mechanical processing industry.Because prior art is when carrying out bore hole to workpiece, normally with clamping workpiece on the chuck of lathe spindle, lathe spindle drives the workpiece rotation.Forming-tool is fixed on the cutter deck of lathe.The workpiece rotation, forming-tool is fixed, through the relative motion of forming-tool and workpiece cut is carried out in the hole on the workpiece.But in some cases, if workpiece is too big, lathe can't clamping or workpiece endoporus and the workpiece centre of gyration eccentric when big, the restriction that receives the engine lathe radius of gyration just can't be processed.Must use more large-scale lathe equipments.
Summary of the invention
The purpose of
the utility model is, provides a kind of lathe to use boring device.To solve the processing problems of the bigger workpiece hole of large-scale workpiece that engine lathe can't clamping or workpiece endoporus and workpiece centre of gyration off-centre, to overcome the deficiency of prior art.
The technical scheme of the utility model
a kind of lathe is used boring device, comprises forming-tool; The middle part of forming-tool is provided with steady pin, and steady pin and saddle are hinged; The afterbody of forming-tool is provided with sliding pin, and the skewed slot on sliding pin and the knife bar is slidingly connected; The front end of forming-tool is provided with cutter head; Cylinder on saddle and the knife bar is slidingly connected, and is connected through pull bar between saddle and the knife bar, is with spring on the pull bar.
aforesaid lathe is with in the boring device, and said pull bar two ends are provided with screw thread, and pull bar one end is threaded with screwed hole on the knife bar, and the counterbore that the pull bar other end passes on the saddle is connected with saddle with nut through packing ring.
aforesaid lathe is with in the boring device, and said saddle outside end face is provided with the location ball.
aforesaid lathe is with in the boring device, and said knife bar tail end cylindrical is a Morse's taper, and is identical with the Morse's taper in lathe spindle hole; Knife bar tail end central authorities are provided with screwed hole.
compared with prior art; The utility model has changed the traditional approach with the lathe bore hole; It is with the knife bar clamping of forming-tool through the utility model on lathe spindle, and the screwed hole secure fixation through knife bar tail end central authorities drives the knife bar rotation by lathe spindle.Workpiece is fixed on the saddle of lathe.Workpiece is fixed, through the relative motion between the forming-tool that rotates and the workpiece of fixing cut is carried out in the hole on the workpiece.Adopt the utility model device solves hole or workpiece endoporus and the bigger workpiece of workpiece centre of gyration off-centre on machining large workpiece on the engine lathe, overcome the deficiency of prior art.The utlity model has simple in structure, easy to use and reliable, characteristics such as working (machining) efficiency is high, and crudy is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in
accompanying drawing: the 1-knife bar, the 2-spring, the 3-pull bar, the 4-packing ring, the 5-nut, the 6-forming-tool, the 7-steady pin, 8-locatees ball, 9-saddle, 10-skewed slot, 11-sliding pin.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.A kind of lathe is used boring device, and is as shown in Figure 1, and a kind of lathe is used boring device, it is characterized in that: comprise forming-tool 6; The middle part of forming-tool 6 is provided with steady pin 7, and steady pin 7 is hinged with saddle 9; The afterbody of forming-tool 6 is provided with sliding pin 11, and the skewed slot 10 on sliding pin 11 and the knife bar 1 is slidingly connected; The front end of forming-tool 6 is provided with cutter head; Saddle 9 is slidingly connected with cylinder on the knife bar 1, is connected through pull bar 3 between saddle 9 and the knife bar 1, is with spring 2 on the pull bar 3.Pull bar 3 two ends are provided with screw thread, and pull bar 3 one ends are threaded with screwed hole on the knife bar 1, and the counterbore that pull bar 3 other ends pass on the saddle 9 is connected with saddle 9 with nut 5 through packing ring 4.Said saddle 9 outside end faces are provided with location ball 8.Said knife bar 1 tail end cylindrical is a Morse's taper, and is identical with the Morse's taper in lathe spindle hole; Knife bar 1 tail end central authorities are provided with screwed hole.
During the bigger workpiece of the device that
the utilize the utility model hole on the machining large workpiece or workpiece endoporus and workpiece centre of gyration off-centre on engine lathe; Through turnbuckle knife bar 1 rear end Morse's taper cylindrical is fixed in the lathe spindle Morse's taper hole earlier, processing work is fixed on the lathe saddle; It is motionless that mobile then lathe saddle makes saddle 9 and ball 8 contact with workpiece, and machine this moment, utilizes the rotating band moving knife bar 1 of lathe spindle to rotate; Move the lathe saddle once more, workpiece heads on saddle 9 and moves backward with ball 8, because saddle 9 middle parts are hinged with forming-tool 6, so when behind saddle 9, moving, drive forming-tool 6 and outwards rotate cutting workpiece.The size in hole reaches cutting effect by saddle 9 control that moves up and down.
