In the prior art, the machining hole is usually subjected to two procedures of rough machining and finish machining, a tool is changed after rough machining, and finish machining is carried out, so that a large amount of time is wasted in tool changing and positioning, and the hole machining efficiency is low.
SUMMERY OF THE UTILITY MODEL
in view of the deficiency of the background art, the utility model provides a conducting bar sword, the technical problem that solve is the machining efficiency of conducting bar sword among the prior art low.
For solving the technical problem, the utility model provides a following technical scheme:
The guide strip cutter comprises a cutter handle and a cutter head coaxially connected with the cutter handle, wherein a plurality of steel guide strips are arranged on the periphery of the cutter head, the steel guide strips are lubricated by cooling liquid, and the steel guide strips are axially arranged in parallel with the cutter head and are uniformly distributed in the circumferential direction;
The tool bit front end has the stair structure, the stair structure leans on preceding terminal surface periphery to install a plurality of rough machining blades, the stair structure leans on the terminal surface periphery of back to install a plurality of finish machining blades, and the machining diameter A of rough machining blade is less than the machining diameter B of finish machining blade.
Preferably, conical threaded holes of the half-open structure are arranged on the tool bit adjacent to the finish machining blades, openings are formed in the side walls, close to the finish machining blades, of the conical threaded holes to form the conical threaded holes of the half-open structure, conical bolts are connected with the conical threaded holes in an internal thread mode, and the side faces of the conical bolts are tightly attached to the finish machining blades through the openings.
preferably, the steel conducting bar is fixedly connected with the periphery of the cutter head through a countersunk screw.
Preferably, the number of the rough machining blade and the fine machining blade is 3, and the 3 rough machining blades and the 3 fine machining blades are distributed at intervals.
Compared with the prior art, the utility model, following beneficial effect has at least:
1) The rough machining blade and the finish machining blade are integrated on one cutter head, the rough machining blade is in front of the cutter head, the machining diameter of the rough machining blade is small, and the machining diameter of the finish machining blade is large, so that when the guide bar cutter is used for machining holes, the cutter head axially advances, the rough machining blade firstly machines the hole wall for one circle, and then the finish machining blade machines the hole wall for one circle, and therefore the one-time rough machining and finish machining operation on the hole wall is achieved;
2) the guide bar cutter can adjust the machining diameter of a finish machining blade, and the specific adjusting method comprises the following steps: through rotatory taper bolt, adjustment taper bolt stretches into the length of toper screw hole for taper bolt extrudees finish machining blade, and elastic deformation takes place for the screw of fixed finish machining blade, thereby makes finish machining blade take place small removal (the migration range is no longer than 0.1mm) along the tool bit, through the adjustment, can make the machining dimension of each finish machining blade unanimous, also can guarantee that finish machining blade is higher than the steel gib block by 0.03 ~ 0.05 mm.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a schematic view of the present invention;
Fig. 2 is a top view of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
as shown in fig. 1 and 2, the guide bar cutter comprises a cutter handle 1 and a cutter head 2 coaxially connected with the cutter handle 1, wherein a plurality of steel guide bars 3 are arranged on the periphery of the cutter head 2, the steel guide bars 3 are lubricated by cooling liquid, and the steel guide bars 3 are axially arranged parallel to the cutter head 2 and are circumferentially and uniformly distributed;
The front end part of the tool bit 2 is provided with a step structure 4, the periphery of the end surface of the step structure 4 close to the front is provided with a plurality of rough machining blades 5, the periphery of the end surface of the step structure 4 close to the rear is provided with a plurality of finish machining blades 6, and the machining diameter A of each rough machining blade 5 is smaller than the machining diameter B of each finish machining blade 6.
Rough machining blade 5 and finish machining blade 6 are integrated on a tool bit 2, rough machining blade 5 is preceding, finish machining blade 6 is back, rough machining blade 5's machining diameter is little, finish machining blade 6's machining diameter is big, consequently, when using this conducting bar sword processing hole, tool bit 2 is when advancing along the axial, rough machining blade 5 is to the hole wall processing a week earlier, finish machining blade 6 is to the hole wall processing a week later, realized disposable to the hole first rough machining, finish machining operation again, machining efficiency has been improved.
A conical threaded hole 7 with a half-open structure is formed in the cutter head 2 adjacent to each finish machining blade 6, an opening 9 is formed in the side wall, close to the finish machining blade 6, of the conical threaded hole 7 to form the conical threaded hole 7 with the half-open structure, a conical bolt 8 is connected with the conical threaded hole 7 in a threaded mode, and the side face of the conical bolt 8 is tightly attached to the finish machining blade 6 through the opening 9.
