Abstract
The utility model relates to an internal thread clamp-type finishing tool for large-sized heavy-duty trapezoidal nuts and adopts the technical scheme as follows: the internal thread clamp-type finishing tool for large-sized heavy-duty trapezoidal nuts comprises a cutter body and a cutter blade, the cutter body comprises a cutter bar and a cutter body, a plane is machined at the lower part of the cutter bar and serves as a cutter-loading alignment reference plane, a square hole is formed on the cutter bar, a cutter blade basal plane is formed on one side of the square hole, the cutter blade basal plane is perpendicular to the cutter-loading alignment reference plane, a pressing screw is arranged on the end surface of the cutter bar and mounted axially, and a pretension recess is formed on the cutter body. According to the technical scheme, the high-precision cutter blade that is directly inspected and qualified is adopted to ensure the accuracy in half of thread angle; the cutter-loading accuracy and efficiency are increased by the fine adjustment of the screw and the alignment of the cutter-loading alignment reference plane on the cutter body; and the cutter presetting operation is not required when changing the cutter blade after the tool is assembled.
Description
Technical field
The utility model 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 of large-scale, heavy trapezoidal screw pair, the required precision of nut thread form half-angle is more and more higher.Current market does not have this type of dedicated tool, and many producers processing nut inner thread is by homemade simple and easy internal screw cutting tool, and the thread form half-angle guarantees that by the model tool setting 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 utility model is at the existing in prior technology shortcoming, and a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool is provided, and the high accuracy blade after it adopts directly detection qualified is guaranteed thread form half-angle precision; By the dress of the dress cutter centering datum level centering on micrometer adjusting screw, cutter hub cutter precision height, efficient height; Do not need tool setting again when once installing back tool changing sheet.
The utility model is realized by following technical measures: a kind of large-scale, heavily loaded trapezoidal nut internal thread machine folder finishing tool, it comprises cutter hub, blade, described cutter hub comprises knife bar and cutter hub, the knife bar bottom is processed with the plane as dress cutter centering datum level, described knife bar is provided with square hole, and a side of described square hole is the blade basal plane, and described blade basal plane is vertical with dress cutter centering datum level, described 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 utility model 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 utility model is by the dress of the dress cutter centering datum level centering on micrometer adjusting screw, cutter hub cutter precision height, efficient height 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.

Fig. 2 is the B-B cutaway view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
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,, this programme is set forth below by a specific embodiment.
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, described knife bar 1 bottom is processed with the plane as dress cutter centering datum level 6, described knife bar 1 is provided with square hole 8, and a side of described square hole 8 is a blade basal plane 7, and described blade basal plane 7 is vertical with dress cutter centering datum level 6, described 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.
The pretension pit of earlier the push type broach screw being aimed on the cutter hub during dress cutter compresses in advance, adjust 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, square hole one side is the blade basal plane, 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,, not need tool setting repeatedly, tool setting precision height, efficient height, the internal thread thread form half-angle precision height of processing with this cutter processing nut inner thread.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model 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 utility model also should belong to protection domain of the present utility model.
