Abstract
The invention discloses a cylindrical pin bolt chamfering tool. The cylindrical pin bolt chamfering tool comprises a cutter bar and a blade, wherein the side surface of the cutter bar is provided with a quadrate hole with the shape as the same as that of the blade; the blade is fixed in the quadrate hole of the cutter bar; the working surface of the blade is semicircular and is provided with a cutting edge; the end face of the cutter bar is provided with a positioning hole along the axial central line; the positioning hole is intersected with the cutting edge of the blade; and the side surface of the cutter bar is radially provided with a chip removal hole which is intersected with the cutting edge of the blade. The chamfering tool is convenient and easy to use, and can be used once being mounted on an electric drill; and without moving a work-piece, the cutting edge of the cutter cuts by surrounding a seamed edge of a to-be-cut cylindrical pin under the action of the positioning hole to realize chamfering. Therefore, the cylindrical pin bolt chamfering tool increases processing efficiency greatly and solves the rapid chamfering problem of the pin bolt with the diameter less than 2 mm on a precise tooling efficiently.
Description
Technical field
The present invention relates to the cylindrical pins chamfering tool in a kind of tool fixture manufacture process.
Background technology
In the tool fixture manufacture process, some frock need to be installed many diameters less than the 2mm shop bolt, because of diameter too little can't be on equipment the clamping chamfering, secondly, when reprocessing or change a social system frock, some installs many alignment pins above frock, the large moment matrix of these pins is arranged or is equally distributed on a plane or bar, and can't pull down and carry out the end face chamfering.Processing method is to repair with Pneumatic grinding machine or manual file at present, inefficiency, manual chamfering irregularity.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of cylindrical pins chamfering tool is provided.
Purpose of the present invention is achieved through the following technical solutions:
The cylindrical pins chamfering tool, characteristics are: comprise knife bar and blade, described knife bar side has the square hole consistent with blade shapes, described blade is fixed in the square hole of knife bar, described blade work face semicircular in shape and have cutting edge, described knife bar end face center line vertically has locating hole, and locating hole and blade cut sword intersect, described knife bar side radially has chip-removal hole, and chip-removal hole and sheet cutting edge intersect.
Further, above-mentioned cylindrical pins chamfering tool, described blade and knife bar interference fits also are screwed in the square hole of knife bar.
Further, above-mentioned cylindrical pins chamfering tool, the diameter of described locating hole are 2mm.
Again further, above-mentioned cylindrical pins chamfering tool, the diameter of described chip-removal hole are 3mm.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:
chamfering tool of the present invention is easy to use, as long as it is arranged on electric hand drill and can uses, workpiece is motionless, the cutting edge of cutter is realized chamfering around being cut the cutting of straight pin seamed edge under the effect of locating hole, change a large amount of cylindrical pins of traditional tool fixture and can't be clamped in the difficulty of chamfering on lathe or other equipment because diameter is too little, during for the reprocessing or change a social system of some tool fixture, it is non-removable that many cylinders are arranged on some frock, thereby the Tool in Cutting sword rotates cutting fast fast centered by the locating hole center of circle, improved greatly working (machining) efficiency, efficiently solve on accurate frock diameter less than the quick chamfering problem of 2mm pin.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention;
The A-A cross-sectional schematic of Fig. 2: Fig. 1.
The specific embodiment
Can not pull down the characteristics of processing for the pin of some tool fixture, adopt workpiece motionless, the cutting edge of cutter is realized chamfering around being cut the cutting of straight pin seamed edge under the effect of locating hole.
as Fig. 1, shown in Figure 2, the cylindrical pins chamfering tool, comprise knife bar 1 and blade 2, knife bar 1 side has the square hole consistent with blade shapes, blade 2 and knife bar 1 interference fits also are screwed in the square hole of knife bar, screw passes screw hole 6 and connects with blade 2, blade work face semicircular in shape and the forming and cutting sword 5 with milled anterior angle and relief angle, knife bar end face center line vertically has locating hole 3, the diameter of locating hole 3 is 2mm, than the processed large 0.05mm of cylindrical alignment pin diameter, so that locating hole can be easily and is inserted in easily by the construction cylindrical pins.Locating hole 3 intersects with the blade cut sword, and the knife bar side radially has chip-removal hole 4, and the diameter of chip-removal hole 4 is 3mm, and chip-removal hole 4 intersects with the blade cut sword.
During concrete the application, the knife bar of cutter partly is clamped in the drill chuck of electric hand drill, start electric drill, locating hole is inserted in processed straight pin and exerts pressure, rotation along with half circular knife, processed straight pin end face is cut to the semicircle sphere shape, and iron filings are discharged from chip-removal hole, reaches the purpose of rapid processing.
above-mentioned chamfering tool is easy to use, as long as it is arranged on electric hand drill and can uses, change a large amount of cylindrical pins of traditional tool fixture and can't be clamped in the difficulty of chamfering on lathe or other equipment because diameter is too little, during for the reprocessing or change a social system of some tool fixture, it is non-removable that many cylinders are arranged on some frock, chamfering after discharge processing brachymemma, conventional method is to repair with instruments such as files one by one by hand, efficient is extremely low, and use above-mentioned chamfering tool, thereby adopt the Tool in Cutting sword to rotate cutting fast fast centered by the locating hole center of circle, improved greatly working (machining) efficiency, efficiently solve on accurate frock diameter less than the quick chamfering problem of 2mm pin.
What need to understand is: the above is only the preferred embodiment of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
