Abstract
The invention discloses a small-bore chamfering tool with convenience in operation and high quality and efficiency in chamfering and burr removal. The small-bore chamfering tool comprises a cutter bar, a support sleeve, a wedge block, an adjusting screw, a cutting blade, a rivet and a set screw, wherein the hardness of the cutting blade is greatly higher than that of sand paper, so that the cutting blade can remove hard burrs at the juncture between a small hole and a large hole; the rivet and a pin hole of the cutter bar are in clearance fit, the cutter bar can be rotated around the rivet, the wedge block compresses the cutter bar downwards when the adjusting screw is rotated, thus enabling the cutter bar to swing along the axial line of the support sleeve and finally keep at a certain working angle, so that the cutting blade is in contact with a working surface better; when the cutter bar swings along the axial line of the support sleeve at a larger angle, burrs in a hole with a larger diameter can be eliminated; and when larger torque is needed, a torque increasing bar can be installed at the outer upper part of the support sleeve to increase the cutting force of the cutting blade.
Description
Technical field
The present invention relates to a kind of small-bore chamfer tool, particularly little Hole chamfering and the deburring of aperture in 10~20mm scope.
Background technology
The situation that occurs aperture and macropore intersection need chamfering and deburring in production practices through regular meeting, routine operation are to adopt scraper, file to carry out manual chamfering, and ultralong deep hole is tied up sand paper deburring, chamfering with long iron pipe at head.But this operation deburring, chamfering inconvenient operation, burr can't make an overall screening totally, and product quality is difficult to guarantee that production efficiency is low that operation easier is big.
Summary of the invention
The object of the present invention is to provide a kind of easy to operate, chamfering flash removed quality height and the high small-bore chamfer tool of efficient, be particularly suitable for macropore and aperture and intersect, and the very long situation of macropore axial dimension.
The present invention includes knife bar, support set, voussoir, adjustment screw, blade, rivet, holding screw, knife bar top and splicing sleeve bottom have corresponding pin-and-hole, rivet is fixed on knife bar on the support set, the pin-and-hole of rivet and support set is an interference fit, and the pin-and-hole of rivet and knife bar is a matched in clearance; The knife bar bottom has a groove, and groove is built-in with blade, and blade is fixed on the knife bar by holding screw, and holding screw scribbles locking glue; Splicing sleeve top has screw, adjusts screw and is installed in this screw, between knife bar and the adjustment screw voussoir is housed, and voussoir bottom and knife bar top respectively have corresponding inclined-plane, and voussoir can be in knife bar 1 upper surface slide.
The outer top of described support set is equipped with and adds torsion bar, increases the cutting force of blade.
Advantage of the present invention is:
1, blade is fixed in the groove of knife bar by holding screw, is not easy to become flexible; The hardness ratio sand paper of blade much bigger can be removed the hard thorn of aperture and macropore intersection;
2, the pin-and-hole of knife bar and rivet are matched in clearance, and knife bar can rotate around rivet, and therefore screw is adjusted in rotation, and voussoir pushes knife bar downwards, can make knife bar along the swing of support set axis, keep certain operating angle at last, can make blade touch working face better;
3, knife bar when big, can also be removed the burr in the bigger endoporus of diameter along the angle of support set axis swing;
4, be coated with locking glue on the holding screw, blade is installed again, can prevent that blade from getting loose in process, guarantee the smooth and easy of operating process.
Description of drawings
Fig. 1 adjusts the longitudinal sectional drawing of screw tightening state for the present invention.
Fig. 2 adjusts the longitudinal sectional drawing that screw unscrews state for the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes knife bar 1, support set 2, voussoir 3, adjustment screw 4, blade 5, rivet 6, holding screw 7.The bottom of the top of knife bar 1 and support set 2 has corresponding pin-and-hole, rivet 6 passes pin-and-hole knife bar 1 is fastenedly connected on support set 2, rivet 6 is an interference fit with the pin-and-hole of support set 2, and rivet 6 is a matched in clearance with the pin-and-hole of knife bar 1, and knife bar 1 can rotate around rivet 6.Knife bar 1 bottom has the cutter groove, and blade 5 is fixed in the cutter groove by holding screw 7, scribbles happy safe glue between cutter groove and the blade 5, can prevent that blade 5 from getting loose in process.Support set 2 tops have screw, adjusting screw 4 is installed in this screw, adjust between screw 4 and the knife bar 1 voussoir 3 is installed, the top of the bottom of voussoir 3 and knife bar 1 has corresponding inclined-plane, and voussoir 3 can make knife bar 1 deflection certain angle in the upper surface slide of knife bar 1.As shown in Figure 2, the loosening screw 6 of adjusting, voussoir 7 breaks away from knife bar 1, knife bar 1 is got back to support set 2 central axis positions under the gravity effect, blade 3 stretches out knife bar and partly stretches into crossing hole site, screws to adjust screw 6, voussoir 7 extruding, make angle of knife bar inclination, blade 3 touches the position that needs processing, and rotational support cover 2 can be implemented processing.
When the bigger moment of needs, install on the top of support set 2 and to add torsion bar 8, increase the cutting force of 5 pairs of processing works of blade.
