Abstract
The invention discloses a mechanically-clamped finishing tool for an internal thread of a large-sized and heavy-load trapezoid nut. The invention has the technical scheme that the mechanically-clamped finishing tool for the internal thread of the large-sized and heavy-load trapezoid nut comprises a tool body and a blade, wherein the tool body comprises a tool shank and the tool body; a plane as a tool-mounting aligning datum plane is processed at the lower part of the tool shank; the tool shank is provided with a square hole; a blade datum plane is arranged at one side of the square hole and is perpendicular to the tool-mounting aligning datum plane; an axially-mounted tool-pressing screw is arranged on the end surface of the tool shank; and the tool body is provided with a pre-tightened concave pit. According to the technical scheme, the precision of a thread half-angle is ensured by adopting the directly-detected and qualified high-precision blade; high aligning and tool-mounting precision and efficiency of the tool-mounting aligning datum plane on the tool body through a fine-tuning screw are obtained; and no secondary tool setting is required when the blade is replaced after one-time mounting.
Description
Technical field
The present invention is a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool.
Background technology
Along with current domestic manufacturing large-scale, jumbo develops, more and more to the demand that large-scale, heavy trapezoidal screw is secondary, the required precision of nut thread form half-angle is increasingly high.Current market does not have this type of dedicated tool, and many producers processing nut inner thread leans on homemade simple and easy internal screw cutting tool, and the thread form half-angle leans on the model tool setting to guarantee that error is big; Because of with bit ga(u)ge tool setting repeatedly, dress cutter precision is low, efficient is low during cutter for dress, and whenever changing a cutter all needs tool setting again, and this obviously can't satisfy the high-precision requirement of large-scale, heavily loaded nut thread form half-angle.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool is provided, the high accuracy blade after it adopts directly detection qualified is guaranteed thread form half-angle precision; High through the dress cutter centering datum level centering on micrometer adjusting screw, cutter hub dress cutter precision, efficient is high; Do not need tool setting again when once installing back tool changing sheet.
The present invention realizes through following technical measures: a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool, and it comprises cutter hub, blade, said cutter hub comprises knife bar and cutter hub; The knife bar bottom is processed with the plane as dress cutter centering datum level; Said knife bar is provided with square hole, and a side of said square hole is the blade basal plane, and said blade basal plane is vertical with dress cutter centering datum level; Said knife bar end face is provided with the push type broach screw of axial installation, and cutter hub is provided with the pretension pit.
Concrete characteristics of the present invention also have, and also are provided with micrometer adjusting screw on the above-mentioned cutter hub.
Above-mentioned knife bar is provided with cooling device.
The beneficial effect of this programme can learn that the present invention is high through the dress of the dress cutter centering datum level centering on micrometer adjusting screw, cutter hub cutter precision, efficient is high according to the narration to such scheme; Do not need tool setting again when once installing back tool changing sheet, have cooling device on the cutter hub, be easy to cooling.

Among the figure, 1, knife bar, 2, blade, 3, the push type broach screw, 4, micrometer adjusting screw, 5, cooling device, 6, dress cutter centering datum level, 7, the blade basal plane, 8, square hole, 9, the pretension pit, 10, cutter hub.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
As shown in the figure, a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool, it comprises cutter hub 10, knife bar 1, blade 2; Said knife bar 1 bottom is processed with the plane as dress cutter centering datum level 6; Said knife bar 1 is provided with square hole 8, and a side of said square hole 8 is a blade basal plane 7, and said blade basal plane 7 is vertical with dress cutter centering datum level 6; Said knife bar 1 end face is provided with the push type broach screw 3 of axial installation, also is provided with pretension pit 9 and micrometer adjusting screw 4 on the cutter hub 10.Wherein, knife bar 1 is provided with cooling device 5.
Aim at the pretension pit pre-compacted on the cutter hub to the push type broach screw earlier during the dress cutter; The adjustment micrometer adjusting screw with dial gauge centering cutter hub basal plane with compress the push type broach screw after machine tool guideway is parallel; Blade is packed in the knife bar square hole, and square hole one side is the blade basal plane, and this basal plane becomes 90 degree with dress cutter basal plane; Compress blade with the push type broach screw axial, guarantee that blade angle of thread center line is vertical with the knife bar basal plane.Only need unclamp the push type broach screw during tool changing sheet and adorn new blade pressing screw and do not need tool setting, with this cutter processing nut inner thread, not need tool setting repeatedly, the tool setting precision is high, efficient is high, and the internal thread thread form half-angle precision of processing is high.
The present invention can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
