Abstract
The invention discloses a novel boring cutter bar with an entire rolling function. A hole vertical to the axis of the cutter bar body is formed on the cutter bar body, and a channel is formed on the axis of the cutter bar body and is communicated with the hole; two pistons are provided with sealing rings and correctly installed in a through hole; a ball is arranged on a concave spherical surface of the head part of each piston and fixed by a ball cap; and a rotary joint is arranged on the mouth part of an end channel of the cutter bar body. In operation, a boring cutter bores the hole first, then a pressure source is introduced into the rotary joint and enters a pressure chamber through a channel to push the pistons open, and the pistons tightly press the ball on the inner hole wall of a workpiece and roll the inner hole wall of the workpiece with the rotary advancement of the cutter bar body. Under the support action of the pistons and by correspondingly increasing the rigidity of the cutter bar body, the cutter bar body is difficult to shake, so that the processing quality of the hole is improved and the phenomenon of cutter cracking can be effectively prevented.
Description
Technical field
The present invention relates to a kind of boring cutter bar, particularly a kind of boring cutter bar of novel whole roll extrusion function.Belong to machinery manufacturing technology field.
Background technology
In Machine Manufacturing Technology, the processing in hole generally need be passed through heavy boring, right boring or grinding, each above-mentioned procedure all independently carries out, so not only production efficiency is low, simultaneously in the boring deep hole, because it is long that boring cutter bar is stretched, also cause the vibrations of knife bar easily, not only collapse cutter easily, the surface quality in hole is descended.
Summary of the invention
The objective of the invention is to: the boring cutter bar that a kind of novel whole roll extrusion function is provided, this boring cutter bar can be in bore hole, it taps into capable roll extrusion polishing processing to subsequent openings, improve the surface quality in hole, not only improve the efficient of the machining in hole, the rolling tools that are arranged at simultaneously on the knife bar play a kind of stable support effect to knife bar, overcome present boring cutter bar in the boring deep hole, because it is longer that knife bar stretches out, stiffness descends, the situation generation that causes the quality decline of machining hole easily even collapse cutter.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of boring cutter bar of novel whole roll extrusion function, and it is by the knife bar body, boring cutter, the spin pressure cap, ball, piston, sealing ring, swivel joint is formed.It is characterized in that on the knife bar body with the knife bar body axis perpendicular open the hole, piston is installed at two ends in through hole, form the hydraulic cylinder of sealing in the middle of two pistons, link to each other with above-mentioned through hole along the axial location open walk of the other end of knife bar body, in order to make of the access of knife bar body at rotation status downforce gas or liquid, end at passage has been installed swivel joint, described in the above piston, its head is made concave spherical surface, has only screw thread on the cylindrical, ball is placed in the groove of piston crown, the inwall of spin pressure cap be shaped on the outer garden of piston crown on identical internal thread, the ball pressure cap is screwed on the screw thread of piston crown cylindrical, ball is fixed, prevent that it from coming off.The boring cutter of being installed on the knife bar body is the same with conventional installation method, according to job requirement, can be fixedly connected, also can be to float to connect.
Its working procedure is: boring cutter at first carries out boring processing to the hole in the work, then feed pressure source in the swivel joint, pressure source is through passage b, entering pressure chamber a promotion piston opens, piston is pressed on ball on the inner hole wall of workpiece c, and the inner hole wall that advances to workpiece c with the rotation of knife bar body carries out rolling and processing, because the supporting role of piston, also increase the stiffness of knife bar body accordingly, make the knife bar body be not easy vibrations, improve the crudy in hole, and can effectively prevent to collapse the generation of cutter phenomenon.
Beneficial effect: owing to adopted boring cutter bar in bore hole, to carry out rolling and processing to the hole, so have the crudy height, the characteristics that production efficiency is higher, the supporting role of the piston tool setting body of rod in addition, can strengthen the stiffness of knife bar body significantly, not only favourable and the crudy that improves bore hole can also prevent to collapse simultaneously the generation of cutter phenomenon.
Description of drawings
Accompanying drawing is a principle assumption diagram of the present invention.
Shown in the figure: 1, knife bar body; 2, boring cutter; 3, ball pressure cap; 4, ball; 5, piston; 6, sealing ring; 7, swivel joint.
The specific embodiment
On knife bar body (1), the make hole a perpendicular with its axis makes passage b on the axis of knife bar body (1), and itself and hole a are connected the sealing ring (6) of packing on two pistons (5), and correct it being installed among the through hole a simultaneously, ball (4) is installed in the head concave spherical surface of piston (5), and be fixed with ball pressure cap (3), swivel joint (7) is installed the oral area with the end passage b of knife bar body (1).Boring cutter in the work (2) at first carries out boring processing to the hole, then feed pressure source in the swivel joint (7), pressure source is through passage b, entering pressure chamber a promotion piston opens, piston (5) is pressed on ball (4) on the inner hole wall of workpiece c, and the inner hole wall that advances to workpiece c with the rotation of knife bar body (1) carries out rolling and processing, because the supporting role of piston (5), also increase the stiffness of knife bar body (1) accordingly, make knife bar body (1) be not easy vibrations, improve the crudy in hole, and can effectively prevent to collapse the generation of cutter phenomenon.
Claims (3)
1. the boring cutter bar of a novel whole roll extrusion function, it is characterized in that: on knife bar body (1), the make hole a perpendicular with its axis makes passage b on the axis of knife bar body (1), and itself and hole a are connected the sealing ring (6) of packing on two pistons (5), and correct it being installed among the through hole a simultaneously, ball (4) is installed in the head concave spherical surface of piston (5), and be fixed with ball pressure cap (3), swivel joint (7) is installed the oral area with the end passage b of knife bar body (1).
2. the boring cutter bar of a kind of novel whole roll extrusion function according to claim 1, it is characterized in that: boring cutter in the work (2) at first carries out boring processing to the hole, then feed pressure source in the swivel joint (7), pressure source is through passage b, entering pressure chamber a promotion piston opens, piston (5) is pressed on ball (4) on the inner hole wall of workpiece c, and the inner hole wall that advances to workpiece c with the rotation of knife bar body (1) carries out rolling and processing.
3. the boring cutter bar of a kind of novel whole roll extrusion function according to claim 1 and 2, it is characterized in that: because the supporting role of piston (5), also increase the stiffness of knife bar body (1) accordingly, make knife bar body (1) be not easy vibrations, improve the crudy in hole, and can effectively prevent to collapse the generation of cutter phenomenon.
