Abstract
The utility model relates to a flexible boring bar which comprises a boring bar body, a cutter installation hole and a cutter positioning hole; the cutter installation hole is arranged at the lower end of the boring bar body; the cutter positioning hole is formed at the lower part of the boring bar body; a threaded hole is formed at the upper end of the boring bar body; a screw rod is arranged in the threaded hole; a cutter handle connection seat is arranged at the upper end of the screw rod and is internally provided with a motor; an output shaft of the motor is connected with the screw rod; and the motor controls the rotation of the screw rod so as to control the distance between the boring bar body and the cutter handle connection seat. Due to the flexible boring bar, the screw rod can be controlled to screw in or out of the threaded hole through the forward and reverse rotation of the motor according to the depth of the machined hole, so that the purpose of regulation of the length of the screw rod can be achieved, and only one boring cutter is needed when holes in different lengths are machined, therefore, the machining cost is reduced.
Description
Technical field
The utility model relates to a kind of boring bar, refers in particular to a kind of scalable boring bar, belongs to the metal cutting processing technique field.
Background technology
In machining, use boring cutter to carry out hole processing usually.General boring cutter is made up of handle of a knife, boring bar and cutter.Nowadays the boring bar on the market is non-telescoping; The degree of depth and radius according to the hole select the boring cutter of which kind of specification to process; The boring bar of the boring cutter on the market of today is non-telescoping; Will early cause in the hole of the same radius of processing the boring cutter that need prepare quite a few kinds of different sizes because of the degree of depth like this, break-in has increased production cost like this.
The utility model content
The utility model purpose is the scalable boring bar that a kind of flexible convenience is provided, reduces production costs for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of scalable boring bar comprises boring bar body, cutter installing hole, hole, cutter positioning; The lower end of said boring bar body is provided with the cutter installing hole; The bottom of said boring bar body has the hole, cutter positioning; The upper end of said boring bar body has screwed hole; Be provided with screw rod in the said screwed hole; The upper end of said screw rod is provided with the handle of a knife Connection Block; Be provided with motor in the said handle of a knife Connection Block; The output shaft of said motor links to each other with screw rod; The distance between boring bar body and handle of a knife Connection Block is controlled in the rotation of said Electric Machine Control screw rod.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The scalable boring bar of the utility model; Can be according to the degree of depth in hole of processing, the positive and negative control screw rod that transfers through motor changes or produces screwed hole over to, reaches the purpose of adjusting screw(rod) length; Only need one when being implemented in the hole that processes different depth the purpose of boring cutter, thereby reduced processing cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereogram of the scalable boring bar of the utility model;
Accompanying drawing 2 is the cutaway view of the scalable boring bar of the utility model;
Accompanying drawing 3 is the user mode figure of the scalable boring bar of the utility model;
Wherein: 1, boring bar body; 2, cutter installing hole; 3, hole, cutter positioning; 4, screwed hole; 5, screw rod; 6, handle of a knife Connection Block; 7, motor; 8, output shaft.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of scalable boring bar of the utility model shown in accompanying drawing 1-3 comprises boring bar body 1, cutter installing hole 2, hole, cutter positioning 3; The lower end of said boring bar body 1 is provided with cutter installing hole 2; The bottom of said boring bar body 1 has hole, cutter positioning 3; The upper end of said boring bar body 1 has screwed hole 4; Be provided with screw rod 5 in the said screwed hole 4; The upper end of said screw rod 5 is provided with handle of a knife Connection Block 6; Be provided with motor 7 in the said handle of a knife Connection Block 6; The output shaft 8 of said motor 7 links to each other with screw rod 5; 6 distance is controlled between boring bar body 1 and handle of a knife Connection Block in the rotation of said motor 7 control screw rods 5.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The scalable boring bar of the utility model; Can be according to the degree of depth in hole of processing, the positive and negative control screw rod that transfers through motor changes or produces screwed hole over to, reaches the purpose of adjusting screw(rod) length; Only need one when being implemented in the hole that processes different depth the purpose of boring cutter, thereby reduced processing cost.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
