Description
Technical field
It is interior to hole machined field of tool that the utility model relates to machinery industry, is specifically related to a kind of cutter for removing deep hole inner lip burr.
Background technology
At mechanical processing industry, have a lot of workpiece to need it is carried out to through hole, gangs up the processing in hole, after this pores is processed by drilling and milling machine, the peristoma in its hole can leave a lot of burr, must be removed, could meet product technology requirement.How to remove? for the removal of expression at the burr of the hole outer lip of surface of the work, it should be the easier thing of part, but for the hole of depths in workpiece, especially the workpiece of ganging up hole is shaped with to some, as air valve, oil cylinder class workpiece ganged up the removal of the burr of the inn edge in hole, it not really the easy thing of part.At present to the burr removing method on inn edge mainly according to inn towards selecting different cutters, bar rod-type file is generally adopted for inn aperture burr inwardly, bar rod-type file puts in hole, and then by file banking, file and inn edge oblique are rubbed back and forth and rubs, to remove the burr of aperture edge along aperture circumference is mobile; And triangle scraper is generally adopted for inn aperture burr outwardly, this triangle scraper is made up of handle of a knife scraper, and scraper is triangle, is fixed on one end of handle of a knife.When removing burr, this cutter is put in from hole the aperture making triangular scraper drop on this hole, rotate back and forth handle of a knife and make scraper on the edge of aperture, strike off burr on the edge of aperture back and forth.As can be seen here, mode and the cutter of existing removal deep hole inner lip burr are all relatively backward, not only inefficiency, and in operation, slightly do not note, also hole wall can be scratched, make workpiece become substandard products or scrap.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model to provide a kind of deep hole inner lip burr cutter easily.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cutter for removing deep hole inner lip burr, comprise knife bar, blade and locating piece, one end of described knife bar is provided with 2 interval troughs, the bifurcated at one end of knife bar is formed 2 elastic rods and a connecting rod by described interval trough, described elastic rod is positioned at the left and right sides of connecting rod, and described locating piece is arranged on the bottom of connecting rod and between 2 elastic rods, described blade is fixed on the head of elastic rod.
The head of described elastic rod has been arranged on magnet, and described magnet is positioned at the bottom of blade.
Described elastic rod is also provided with the magnet be positioned on the upside of blade.
Described knife bar is socketed with a positioning sleeve.
The material of described locating piece is metal.
The material of described positioning sleeve is plastics.
(3) beneficial effect
The advantage of the cutter for removing deep hole inner lip burr of the present utility model: compared with prior art, because blade to be arranged the head of two elastic rods by the utility model, during use, as long as two elastic rods are inwardly taken the photograph conjunction with finger, blade part diameter is much smaller than aperture, operator notes a little diligently, cutter enters or exit aperture position, the probability that blade scratches hole wall reduces greatly, after blade part crosses hand-hole position, conjunction is taken the photograph in relieving, blade part is greater than aperture, at this moment, as long as rotate knife bar by hand, blade part rotates with this, the burr of aperture edge just can be got rid of by blade soon.Operating efficiency improves greatly.And the utility model structure is simple, easy to operate.And by arranging magnet, thus burr can be held by magnet and take out, without the need to secondary cleaning, cleaning is convenient.Also can limit the elasticity operating range between elastic rod by locating piece, remove burr convenient, blade can be prevented hole wall scratch by positioning sleeve.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-Figure 3, a kind of cutter for removing deep hole inner lip burr, comprise the locating piece 3 of knife bar 1, blade 2 and metal material, one end of described knife bar 1 is provided with 2 interval troughs 4, the bifurcated at one end of knife bar is formed 2 elastic rods 5 and a connecting rod 6 by described interval trough 4, described elastic rod 5 is positioned at the left and right sides of connecting rod 6, and described locating piece 3 is arranged on the bottom of connecting rod 6 and between 2 elastic rods 5, described blade 2 is fixed on the head of elastic rod 5.During use, as long as two elastic rods are inwardly taken the photograph conjunction with finger, blade part diameter is much smaller than aperture, operator notes a little diligently, cutter enters or exit aperture position, and the probability that blade scratches hole wall reduces, after blade part crosses hand-hole position greatly, conjunction is taken the photograph in relieving, blade part is greater than aperture, at this moment, as long as rotate knife bar by hand, blade part rotates with this, and the burr of aperture edge just can be got rid of by blade soon.Operating efficiency improves greatly.And the elasticity operating range between restriction elastic rod, remove burr convenient.
The head of described elastic rod 5 has been arranged on magnet 7, and described magnet 7 is positioned at the bottom of blade 2.Described elastic rod 5 is also provided with the magnet 7 be positioned on the upside of blade 2, to be held by the burr after removing take out by this structure by magnet 7, without the need to artificial this deburring again, very convenient.
Described knife bar 1 is socketed with the positioning sleeve 8 of a plastic material, and described positioning sleeve 8 can prevent blade 2 from contacting hole wall and by hole wall scratch, blade can be made again to locate more accurate.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
