Abstract
The invention discloses a novel adjustable double-blade boring cutter and belongs to the field of metal cutting tools. The blades of the conventional novel adjustable double-blade boring cutter cannot be adjusted in position on a cutter arbor. The novel adjustable double-blade boring cutter comprises a cutter arbor, two blades, two blade seats, fastening screws and adjusting screws, wherein the blades are fixedly mounted at the tops of the blade seats; dovetail grooves are formed in the front end of the cutter arbor; dovetail tenons are arranged at the bottoms of the blade seats; the dovetail grooves and the dovetail tenons are correspondingly connected in a matching manner; a waisted hole is formed in each blade seat and runs through the top surface and the bottom surface of the blade seat; the waisted holes penetrate through the dovetail tenons; axial screw holes are formed in the middles of the dovetail grooves; the fastening screws penetrate through the waisted holes and are screwed in the axial screw holes; radial screw holes communicated with the waisted holes are formed in the blade seats; the center lines of the radial screw holes are consistent with the axial directions of the dovetail tenons; and the adjusting screws are screwed in the radial screw holes. According to the invention, the movable blade seats and the adjusting screws are arranged to adjust the distances between the blades and the axle center of the cutter arbor, so that different processing diameters are achieved by the single cutter arbor.
Description
Technical field
The invention belongs to the metal cutting tool field, especially relevant with a kind of double blade boring cutter of ability adjustment processing diameter.
Background technology
Existing new type of adjustable double blade boring cutter is employed in two form of a blade of symmetry fixed installation on the knife bar on the market; The position of blade on knife bar fixed; That is to say the hole boring processing that a kind of knife bar can only corresponding a kind of diameter, after the conversion of aperture, just need more changing knife rod.
Summary of the invention
The object of the invention is exactly to solve the existing new type of adjustable 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 novel adjustable double blade boring cutter of processing diameter.For this reason, the present invention adopts following technical scheme:
New type of adjustable double blade boring cutter comprises knife bar and two blades, it is characterized in that: described new type of adjustable double blade boring cutter also comprises two blade bearings, trip bolt and adjustment screw; Blade is fixedly installed in the blade bearing top, and described knife bar front end is provided with dovetail groove, and 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, and mounting hole is through dovetail, and 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 through the cooperation of dovetail mechanism, and are 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, the trip bolt of screwing then with respect to the knife bar axle center; Blade bearing is fixed, realized increasing the processing diameter.
Use the present invention can reach following beneficial effect: the present invention can regulate the distance of blade with respect to the knife bar axle center through 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 master's apparent direction of the present invention.
Fig. 2 is a left view of the present invention.
The specific embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2, the present invention includes 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, and the bottom of blade bearing 3 is provided with dovetail, and 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, and mounting hole 6 is through dovetail, and the dovetail groove middle part is provided with axial screw; Trip bolt 2 passes mounting hole 6 and is screwed into described axial screw; 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, the trip bolt 2 of screwing then with respect to the knife bar axle center; Blade bearing 3 is fixing, realize increasing the processing diameter.
