Abstract
The utility model discloses a double-blade boring cutter and belongs to the field of a metal cutting tool. The position of the blades of a conventional double-blade boring cutter can not be adjusted on a cutting rod. The double-blade boring cutter comprises a cutting rod, two blades, two blade stands, a fastening screw and an adjusting screw. The blades are fixedly arranged on the tops of the blade stands. The front end of the cutting rod is provided with a dovetailed groove. The bottom ends of the blade stands are provided with a dovetailed tenon. The dovetailed groove is correspondingly mated with the dovetailed tenon. The blade stands are provided with a kidney-shaped hole which passes through the top and the bottom of the blade stands. The kidney-shaped hole passes through the dovetailed tenon. Axial screw hole is arranged in the center of the dovetailed groove. The fastening screw passes through the kidney-shaped hole and is screwed into the axial screw hole. The blade stands are provided with a radial screw hole which is communicated with the kidney-shaped hole. The center line of the radial screw hole is in the same direction with the axial direction of the dovetailed tenon. The adjusting screw is screwed in the radial screw hole. According to the utility model, the movable blade stands and the adjusting screw are disposed so as to adjust the distance between the blades and the axle center of the cutting rod, and different machining diameters can be realized by one cutting rod.
Description
Technical field
The utility model belongs to the metal cutting tool field, and is especially relevant with a kind of boring cutter with double blade.
Background technology
Existing double blade boring cutter adopts two form of a blade of symmetry fixed installation on knife bar on the market, and the position of blade on knife bar fixed, and that is to say the hole boring processing that a kind of knife bar can only corresponding a kind of diameter, just needs more changing knife rod after the conversion of aperture.
The utility model content
The purpose of this utility model is exactly to solve the existing double blade boring cutter blade defective that the position can not be adjusted on knife bar, provide a kind of simple in structure, can adjust the adjustable double blade boring cutter of processing diameter.For this reason, the utility model is by the following technical solutions:
The double blade boring cutter, comprise knife bar and two blades, it is characterized in that: described double blade boring cutter also comprises two blade bearings, trip bolt and adjustment screw, blade is fixedly installed in the blade bearing top, described knife bar front end is provided with dovetail groove, described blade bearing bottom is provided with dovetail, dovetail groove is connected with the dovetail corresponding matching, blade bearing is provided with the mounting hole that runs through end face and bottom surface, mounting hole passes through dovetail, the dovetail groove middle part is provided with axial screw, described trip bolt passes mounting hole and is screwed into described axial screw, blade bearing is provided with the radially screw that connects with mounting hole, radially center line of bolt hole and dovetail axially in the same way, described adjustment screw is screwed in screw radially.
Two blade bearings are installed in the knife bar top by the cooperation of dovetail mechanism, fastening by trip bolt, when needs change the processing diameter, unclamp trip bolt, the turn adjustment screw, adjustment screw leans trip bolt, promote blade bearing outwards slippage in dovetail groove, increase the distance of blade, screw trip bolt then with respect to the knife bar axle center, blade bearing is fixed, realized increasing the processing diameter.
Use the utility model can reach following beneficial effect: the utility model can be regulated the distance of blade with respect to the knife bar axle center by removable blade seat and adjustment screw are set, and a kind of knife bar just can be realized different processing diameters.
Description of drawings
Fig. 1 is the partial sectional view of the utility model master apparent direction.
Fig. 2 is the utility model left view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As Fig. 1, shown in Figure 2, the utility model comprises knife bar 1, two blades 4, two blade bearings 3, trip bolt 2 and adjustment screw 5, blade 4 is fixedly installed in the top of blade bearing 3, the front end of knife bar 1 is provided with dovetail groove, the bottom of blade bearing 3 is provided with dovetail, dovetail groove is connected with the dovetail corresponding matching, blade bearing 3 is provided with the mounting hole 6 that runs through end face and bottom surface, mounting hole 6 passes through dovetail, the dovetail groove middle part is provided with axial screw, and trip bolt 2 passes mounting hole 6 and is screwed into described axial screw, and blade bearing 3 is provided with the radially screw that connects with mounting hole, radially center line of bolt hole and dovetail axially in the same way, adjustment screw 5 is screwed in screw radially.
When needs change the processing diameter, unclamp trip bolt 2, turn adjustment screw 5, adjustment screw 5 leans trip bolt 2, promote blade bearing 3 outwards slippage in dovetail groove, increase the distance of blade, screw trip bolt 2 then with respect to the knife bar axle center, blade bearing 3 is fixing, realize increasing the processing diameter.
