Abstract
The utility model provides a drill bit type erasing knife, relating to the technical field of tools for deburring. The drill bit type erasing knife is composed of a fixed rod, a straight-bar and a slight heavy blade. The bottom of the fixed rod is opened with a hole. The inner wall of the hole has internal screw-threads. The upper part of the straight-bar has the matched external screw-threads. The bottom of the fixed rod is connected in screw thread with the upper part of the straight-bar. The center of the lower end part of the straight-bar is opened with a vertical slot. A mounting hole arranged at the center of the slight heavy blade is arranged on the wall of the both sides of the above vertical slot through the rotation of a rotating shaft. The drill bit type erasing knife has simple structure, convenient usage and can deburr efficiently.
Description
Affiliated technical field
The utility model relates to the instrument of deburring in a kind of machining.
Background technology
At present, at mechanical processing industry, often run into the removal problem of burr on the interior phase perforation arc surface of die cavity, people often use file, sand paper to remove, and its weak point is relatively to require great effort, inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of drill bit type scraper, and this drill bit type blade construction is simple, easy to use, can remove burr efficiently.
In order to achieve the above object, the technical solution of the utility model is: a kind of drill bit type scraper, comprise fixed bar, straight-bar and little blade of laying particular stress on, the bottom of fixed bar has the hole, the inwall in hole has internal thread, and the external screw thread that is complementary is arranged at the top of straight-bar, and the bottom of fixed bar and the top of straight-bar are threaded, be processed with a vertical slotted hole in the middle of the bottom of straight-bar, little installing hole of laying particular stress on the blade center position rotates by a rotating shaft and is assemblied on the two side of above-mentioned vertical slotted hole.
Because this drill bit type scraper comprises fixed bar, straight-bar and little blade of laying particular stress on, the bottom of fixed bar and the top of straight-bar are threaded, be processed with a vertical slotted hole in the middle of the bottom of straight-bar, little installing hole of laying particular stress on the blade center position rotates by a rotating shaft and is assemblied on the two side of above-mentioned vertical slotted hole.During use, can be clamped in the upper end of the fixed bar of this drill bit type scraper in the jig of drilling machine, correct position in the hole to be processed is inserted in the straight-bar bottom, start drilling machine then, little blade of laying particular stress on becomes under centrifugal action and the straight-bar plumbness, when running into rugged cambered surface burr, little lay particular stress on blade just upper and lower move burr is removed clean.Therefore, this drill bit type blade construction is simple, easy to use, can remove burr efficiently.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the partial sectional view of embodiment drill bit type scraper.
The specific embodiment
As shown in Figure 1, a kind of drill bit type scraper, comprise fixed bar 6, straight-bar 4 and little blade 3 of laying particular stress on, this little blade 3 of laying particular stress on is for having the blade of prismatic blade, the bottom of fixed bar 6 has hole 5, the inwall in hole 5 has internal thread, the external screw thread that is complementary is arranged at the top of straight-bar 4, the top of straight-bar 4 changes in the hole 5 of fixed bar by screw thread, the bottom of fixed bar 6 and the top of straight-bar 4 are threaded, be processed with a vertical slotted hole 1 in the middle of the bottom of straight-bar 4, little installing hole of laying particular stress on blade 3 centres rotates by a rotating shaft 2 and is assemblied on the two side of above-mentioned vertical slotted hole 1.During use, can be clamped in the upper end of the fixed bar 6 of this drill bit type scraper in the jig of drilling machine, correct position in the hole to be processed is inserted in straight-bar 4 bottoms, start drilling machine then, little blade 3 of laying particular stress on becomes under centrifugal action and straight-bar 4 plumbness, when running into rugged cambered surface burr, little lay particular stress on blade 3 just upper and lower move burr is removed clean.Therefore, this drill bit type blade construction is simple, easy to use, can remove burr efficiently.
