Abstract
The utility model discloses a trimming cutter bar applied to a borer, aimed at settling the problems that the existing boring and hole machining need the operator to regulate the dimension of extension of the boring cutter by sensation and experience which causes low efficiency and low yield. The trimming cutter bar comprises a boring bar mounted on an existing boring machine, a boring cutter (consisting of a cutter head and a cutter rod) mounted in the cutter hole and is fixed by a cutter-pressing screw, inside the cutter hole, a regulating screw rod which can be used to fine tune the extension dimension of the cutter can also be mounted. As regulation of the extension dimension of the cutter on the boring bar depends on the differential motion of different thread pitches at both ends of the regulating screw rod, and the dimension is changed by revolving the differential bolt, when the above cutter bar is adopted, the fine tuning extent can be calculated accurately in accordance with the rotation angle of the regulating screw rod and the differential value of different pitches, thereby, the efficiency of the boring machine is largely improved, the trouble of multiple cuttings is avoided and the working efficiency is improved; in addition, the product quality is ensured, the yield of boring and machining is increased, and the economic benefits of the enterprise are increased.
Description
Technical field
The utility model belongs to cutter, specifically a kind of fine setting knife bar that is used on the boring machine.
Background technology
On boring machine, workpiece is carried out the boring processing in hole, after boring one cutter is finished, adjust the length that cutter head exposes boring bar, be about to cutter head to next cutter of boring again of transfering to other localities a bit, its way normally gropes to finish with operator's sensation and experience, generally be to rap with tup to be with the rear portion of boring bar to carry out, the size of pounding out is difficult to accurately hold, and particularly all the more so for the right boring of last cutter, the size of striking outward is little, also boring again, repeatedly penetration of a cutting tool is lost time; Struck greatly, the hole is caused scrapping of whole work-piece by the boring conference.Therefore regulate boring cutter tip size inefficiency with operator's sensation and experience, yield rate is low, directly has influence on economic benefit of enterprises.
The utility model content
Technical problem to be solved in the utility model is, overcomes existing boring machining hole and regulates the shortcoming that the overhanging size work efficiency of boring cutter is low, yield rate is low by operator's sensation and experience, provides a kind of boring machine with the fine setting knife bar.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the fine setting knife bar comprises the existing boring bar that is installed on the boring machine, be installed in the tool bore boring cutter of fixing, forming by cutter head and knife bar with the push type broach screw perpendicular to boring bar, in tool bore, the adjusting screw(rod) of the overhanging size of fine-tuning boring cutter is installed also.
The utility model also has following technical characterictic:
Described adjusting screw(rod), having two sections of different pitch by two ends forms, the installation of adjusting screw(rod), be in the tool bore on boring bar, be fixed with cover perpendicular to boring bar, the cover screw rod of adjusting screw(rod) one end, the endoporus that is screwed in cover is positioned at the screw from boring cutter cutter head one end, the pin screw rod of the adjusting screw(rod) other end is screwed in the screw of boring bar tail end;
Described pin screw rod is screwed in the screw of boring bar tail end, is on the close body of rod of tail end of boring bar, passes the body of rod and is vertically fixed with vertical pin, and the pin screw rod passes the centre bore of boring bar tail end, is screwed in the horizontal screw hole on the pin;
The described cover that is fixed in the boring bar hole is the thin-walled cover, on the outer wall that is positioned at the knife bar tail end of cover, has the harmomegathus mouth parallel with self center line.
When regulating the overhanging size of boring cutter, unclamp the push type broach screw, turn the external end head of adjusting screw(rod), differential by the different pitch of bar portion at adjusting screw(rod) two ends reaches the purpose that trace is regulated the boring cutter size.
Advantage of the present utility model and good effect, because the adjusting of boring cutter overhanging size on boring bar, be to utilize the differential principle of the different pitch at adjusting screw(rod) two ends to realize, differential bolt changes by rotating, use above-mentioned knife bar, can be according to the angle of adjusting screw(rod) rotation and the difference of different pitch, grasp amount trimmed through accurately calculating, improved the operating efficiency of boring machine greatly, reduce the repeatedly trouble of penetration of a cutting tool adjustment, improved operating efficiency, guaranteed product quality simultaneously, improved the yield rate of boring processing, also increased economic benefit for enterprise.
Description of drawings
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 analyses and observe for the A-A of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, the fine setting knife bar comprises the existing boring bar 1 that is installed on the boring machine, and be installed in the tool bore 1.1 on the boring bar 1 boring cutter 23 fixing with the push type broach screws, that form by boring cutter cutter head 2.1 and boring bar 2.2 perpendicular to boring bar 1, on the boring cutter 2 in tool bore 1.1, the adjusting screw(rod) 5 of fine-tuning boring cutter 2 overhanging sizes is installed also.
Described adjusting screw(rod) 5, two sections screw rods that had different pitch by two ends are formed.The installation of adjusting screw(rod) 5 is in the tool bore 1.1 on boring bar, is fixed with cover 6 perpendicular to boring bar 1, the cover screw rod 5.2 of adjusting screw(rod) 5 left ends, be screwed in the cover 6 endoporus in the screw of boring cutter cutter head 2.1 ends, the pin screw rod 5.3 of the right-hand member of adjusting screw(rod) 5 is screwed in the screw of boring bar 2.2 tail ends.
Described pin screw rod 5.3 is screwed in the screw of boring bar 2.2 tail ends, is on the boring bar 2.2 close bodies of rod of tail end, is vertically fixed with pin 4, and pin screw rod 5.3 passes the centre bore of boring bar 2.2 tail ends, is screwed in the horizontal screw hole on the pin 4 (referring to Fig. 2).
During use, inner hexagon spanner is inserted in the inner hexagonal hole 5.1 of adjusting screw(rod) 5 left end heads and turn,,, can realize the adjusting of boring cutter 2 overhanging sizes according to differential principle because the pitch of cover screw rod 5.2 and pin screw rod 5.3 is inequality.For example, the cover screw rod 5.2 of adjusting screw(rod) 5 left ends is 2.0 millimeters with cover 6 pitch that cooperate, the pitch that pin screw rod 5.3 cooperates with knife bar is 1.5 millimeters, adjusting screw(rod) 5 whenever revolves and turns around, knife bar 2 just can move 0.5 millimeter, with reference to the dial on the cover 6, angles are spent in adjusting screw(rod) 5 every rotations 15 like this, and knife bar 2 just can move 0.02 millimeter.
