Abstract
The utility model discloses a manual-operated metal hole chamfering device which is used for round hole chamfering of mental workpieces. A tool bar which is provided with a screw groove body rolls to cooperate with a sliding sleeve whose inner side is provided with a steel ball, and the sliding sleeve is fixed in a casing. One end of the tool bar is provided with a tool bit, and the other end of the tool bar is connected with a spring. The component parts are integrated. The utility model cuts the workpieces by using the cooperation of a large guide distance screw groove and the steel ball to convert the rectilinear motion of an auxiliary mechanism into the rotary motion of the tool bit. The utility model which adopts manual mode has the advantages of simple structure and convenient operation, guaranteeing the processing quality of drilling for workpieces.
Description
The utility model relates to the instrument of the garden Hole chamfering on the metal works.
After the metal works boring, remove have specific (special) requirements, generally all answer chamfering, at present owing to the specific purpose tool that does not have chamfering.Therefore, often out in the cold.And chamfering does not cause quality problems easily.As: screw not chamfering can cause faying face injustice (as shown in Figure 1), and the hole, garden of chamfering does not easily influence the precision (as shown in Figure 2) in hole because of collision.And before tapping chamfering, screw tap is cut easily, also helps screw centering and imports.
The garden Hole chamfering of prior art is generally taked after boring, and change the drill bit bigger and carry out chamfering than former aperture, or manual chamfering.
The purpose of this utility model is: design a kind of simple and conveniently, cost is low, is applicable to the specific purpose tool of the garden Hole chamfering on the metal works.
The utility model is to utilize helicla flute, and particularly big helical pitch helicla flute by the rectilinear motion of auxiliary body, makes the spiral cell body under the cooperation of steel ball, rotates, and drives cutter head and cuts.
Casing front end inboard is fixed with sliding sleeve, the sliding sleeve inboard is provided with fixed-site but rotary steel ball, and the helicla flute on steel ball and the knife bar rolls and cooperates, under external force, rectilinear motion by auxiliary body changes rotatablely moving of knife bar, cutter head into, makes cutter head reach the purpose of cutting workpiece.
The utility model need not power, adopts manual mode, and is simple in structure, in light weight, easy to operate, the crudy behind the favourable again assurance Workpiece boring.
The utility model is described in further detail below in conjunction with embodiment:
Fig. 3 is a manual garden Hole chamfering device schematic diagram.
The 1-cutter head, the knife bar of 2-band spiral cell body, 3-sliding sleeve, 4-steel ball, 5-spring, 6-casing.
During chamfering, hold the handle of casing, push away before the cutter head that links to each other with knife bar being put into hole (tool bit diameter should greater than the aperture) reinforcing of workpiece, because cutter head is obstructed, do not do to advance, sliding sleeve and knife bar that cause is fixed on the casing are movingly, at the helicla flute on the knife bar and being fixed under the mating reaction of the steel ball on the sliding sleeve, produce compound motion, be that casing is pushed ahead, moving linearly, and compression spring (spring makes cutter head that certain cutting output be arranged for the power of cutter head), knife bar rotates, and adopts the cutter head that is threaded then to cut work done with knife bar.After chamfering was finished, the elastic force of the spring that relies on compressed was finished knife bar and is resetted when cutter head leaves workpiece.
The shell of this chamfering device can also can be used the engineering plastics injection molded with metal casting or punch forming.
Claims (3)
1, a kind of instrument that is mainly used in the garden Hole chamfering on the metal works, the cutter head that has knife bar and be attached thereto, it is characterized in that knife bar (2) has the spiral cell body, it rolls with the sliding sleeve (3) that is fixed in the casing and have steel ball (4) in the inboard and cooperates, the other end of knife bar and spring (5) join, and casing (6) forms an integral body to above-mentioned part.
2, chamfering device as claimed in claim 1 is characterized in that cutter head (1) and knife bar (2) are for being threaded.
