Abstract
The utility model discloses a reamer with unequally spaced teeth, which is characterized in that included angles W between teeth on semicircular circumference of a cutter tooth section are not the same angle. In addition, the angle deviations between adjacent teeth on the semicircular circumference are not the same. The included angles between the cutter gears on the semicircular circumference are symmetrically distributed with the included angles between the cutter teeth on the other semicircular circumference. The utility model is mainly used for fine processing operation of the metallic hole. When in avoiding reaming, resulting from that the unbalanced cutting effect on the cutter teeth generates circular vibration, a vertical indent is left onto the hole wall; therefore, the reamed hole surface has a relatively fine roughness and circular cylinder level with the hole processing accuracy improved at the same time.
Description
Technical field
The utility model relates to a kind of machine tool, particularly a kind of reamer that is used for the processing of metalwork hole.
Background technology
At present, the fine finishining in hole generally adopts reamer to carry out ream processing on the metalwork, and it is equidistantly uniform that used reamer is generally cutter tooth, and promptly on the largest circumference of cutter tooth part, the angle between teeth between adjacent cutter tooth equates.When reaming with reamer, when producing periodic vibration owing to unbalanced cutting force effect on the reamer cutter tooth, easily make and marked straight line or the vertical indenture of helix on the hole wall, because existing reamer cutter tooth is equidistantly uniform, cause indenture to repeat to deepen and enlarge, thereby the hole of cutting with scissors out is difficult to reach the high request of the cylindricity in surface roughness and hole.
Summary of the invention
The purpose of this utility model is to solve the technical problem that existing reamer can produce the vertical indenture of hole wall, and a kind of cutter tooth that improves metal aperture machining accuracy reamer that is not equally spaced is provided.
The technical solution of the utility model is: the cutter tooth reamer that is not equally spaced, comprise cutter hub part and cutter tooth part, and the cutter tooth number is an even number, improvements are that each angle between teeth W is unequal on cutter tooth semi-circumference partly, i.e. W
1≠ W
2≠ W
3... ≠ W
n, and the difference of adjacent angle between teeth does not wait on the semi-circumference, i.e. W
2-W
1≠ W
3-W
2... ≠ W
n-W
N-1So-called angle between teeth is meant on the largest circumference of cutter tooth part, the central angle that the cutting edge of adjacent cutter tooth is folded.
Further scheme is: the cutter tooth angle between teeth is symmetrically distributed on the cutter tooth angle between teeth on the semi-circumference and second half circumference.
Adopt the utility model to carry out the ream processing in hole, because cutter tooth is not equally spaced, revolution moves certain angle, the indenture that the front cutter tooth is produced is deepened and is enlarged, and can partly eliminate, thereby the hole surface roughness of cutting with scissors out is better, the cylindricity in hole is also better, so the precision in hole improves.

2, constitute cutter tooth on second half circumference on the semi-circumference after 180 ° of the pirouettes;
The cutter that Fig. 6, Fig. 7, Fig. 8, Fig. 9 are respectively Fig. 2, Fig. 3, Fig. 4, knife-tooth structure shown in Figure 5 when fraising behind moving 60 ° of the revolution, each cutter tooth position stack, the cutter tooth distribution map that obtains.
The specific embodiment
With reference to accompanying drawing, as can be seen, the reamer cutter tooth distributed points that designs by knife-tooth structure shown in Fig. 2,3,4,5 is respectively 30,6,18,18 points, and theoretically, distributed points is overstepping the bounds of propriety looses, and the precision of fraising is high more.Present embodiment adopts cutter tooth as shown in Figure 2, after the practice, and the hole of cutting with scissors out, cylindricity is in 0.01, and surface roughness reaches
Compared with existing equidistant 6 tooth reamer (cylindricity 0.015～0.02, surface roughnesses
Obviously improved machining accuracy.
