Abstract
The utility model relates to a cutter used for manufacturing internal thread of a bushing collar, comprising a toolbar and an internal thread manufacturing blade, which is arranged at the end of the toolbar; a special blade is arranged at a part of the toolbar back to the internal thread manufacturing blade and far away from the end of the toolbar; the axial distance between the internal thread manufacturing blade and the special blade is not bigger than half of the collar length; the radial distance between two blade-points of the two blades is smaller than the value of the minimum inner diameter of the collar subtracting the tooth depth of the thread; after finishing the internal thread manufacturing, the internal thread manufacturing blade moves back with a short distance and then the deburring process and other special thread manufacturing processes can be started without changing the cutter spacing so as to save the manufacturing time. The utility model has the advantages of simple structure and high practicability.
Description
Technical field
The utility model relates to the cutter that a kind of internal thread machining is used, and is specially adapted to the screw thread processing of tubing and casing box cupling.
Background technology
97103690.X patent disclosure a kind of method of resection remove the method for screw thread burr, its adopt a deburring blade along the screw thread tooth top direction at burr place by carrying out the chasing feeding with the round thread identical pitch.This method need adopt a special deburring blade, deburring blade is installed on the knife bar different with Cutting blade for machining screw thread, after screw thread machines, changes to the deburring blade station and carry out deburring processing, cause processing rhythm to rise significantly thus, and difficulty is adjusted in processing.
99240438.X patent disclosure a kind of tubing and casing buttress thread joint, this joint is in order to improve anti-stick button effect, different and the normal thread taper of the tooth top tapering of internal thread starting buckle, need to adopt a dedicated tool to process, this cutter is contained on the different stations with Cutting blade for machining screw thread, need change cutter spacing in succession and process, prolong process time, increase processing cost.
Summary of the invention
The purpose of this utility model is the cutter that obtains a kind of special-purpose blade and internal thread machining blade unit, and needn't change cutter spacing after making screw thread machine just can carry out the processing of corresponding deburring or specific screw thread, thereby saves process time, cuts down finished cost.
For achieving the above object, the utility model proposes the cutter that a kind of internal thread machining is used, it comprises knife bar and internal thread machining blade, the internal thread machining blade is installed in the end of knife bar, also is provided with a special-purpose blade with the opposing side of described internal thread machining blade and away from the knife bar end position on this knife bar.
And, the axial spacing of internal thread and special-purpose blade is not more than half of coupling length, the radial spacing of two blade points of a knife deducts the screw thread tooth depth less than the minimum diameter of box cupling, finish the processing of internal thread when the internal thread machining blade after, suitably rollback one needn't be changed cutter spacing than short distance, just can begin to carry out deburring processing and the processing of other specific screw thread, thereby shorten processing rhythm.
Gang tool of the present utility model can be monoblock type, also can be combined type, to be fit to different processing needs.Described special-purpose blade can be a deburring blade, and specific Cutting blade for machining screw thread or sealing surface are processed special-purpose blade.
In the utility model, because internal thread machining and special process all realize, avoided the cutter spacing replacing on a knife bar, can save process time; In addition, internal thread machining blade and special-purpose blade are on a knife bar, and its relative position can accurately be measured, and are very easily for processing adjustment.

The specific embodiment
Embodiment 1
Embodiment 1 is used for the explanation of deburring processing for the utility model.
As shown in Figure 1, the minimum diameter of tubing and casing box cupling 1 internal thread is d
Min, box cupling one start screw length is L
3, L
3Be not more than half of coupling length.
As shown in Figure 2, internal thread machining blade 2 is installed in the end of knife bar 4, also be provided with a special-purpose blade 3 with described internal thread machining blade 2 opposing sides and away from the knife bar end position on knife bar 4, the point of a knife radial distance, d of special-purpose blade 3 and internal thread machining blade 2 is less than the minimum diameter d of internal thread
MinDeduct the screw thread tooth depth, when avoiding internal thread machining blade 2 to cut out internal thread, opposing special-purpose blade 3 is run into the complete thread of having processed.Simultaneously, the axial distance L of special-purpose blade 3 and internal thread machining blade 2 otherwise greater than L
3, also be not more than half of coupling length, to guarantee the knife bar feed.
As shown in Figure 3, Fig. 3 has marked the position when internal thread machining blade 2 cuts out screw thread, because the radial distance of internal thread blade 2 and opposing special-purpose blade 3 is less than the minimum diameter d of internal thread
MinSpecial-purpose blade point of a knife 3 deducts the screw thread tooth depth, so this moment, can not touch manufactured complete thread and damaged screw; Knife bar 4 suitably retreats then, and special-purpose blade 3 cuts out a little opposing direction incision screw initial thread at internal thread blade 2 and buckles, and carries out the processing of deburring processing or specific screw thread, as shown in Figure 4.
As shown in Figure 5, the minimum diameter d of the special thread joint of special snapping hoop 5
Min, X is the distance of screw thread end point to the sealing surface circular arc, the L among Fig. 6, d represent the axial and radial distance between sealing surface processing blade 7 and internal thread machining monodentate blade 6 points of a knife respectively.
As shown in Figure 6, the monodentate blade 6 of special button internal thread machining special use is installed in the end place of knife bar 4, the blade leading flank is concordant with the knife bar front end face, enough short and run into the torque resistant step of workpiece when being unlikely to cut out screw thread with the distance of guaranteeing monodentate blade and leading flank, opposing direction at internal thread machining monodentate blade 6 is provided with sealing surface processing blade 7, sealing surface processing blade 7 is that L, radial distance are d with the axial distance of the complete tooth of screw thread of internal thread machining monodentate blade 6, and d is less than the minimum diameter d of special thread joint
MinDeduct the screw thread tooth depth.Do not interfere on two locus of blade in joint.As Fig. 7, shown in Figure 8, after screw thread machined, the knife bar feed began the processing of special button sealing surface, thereby can realize the processing of screw thread and sealing surface on a cutter spacing before making sealing surface processing blade place sealing surface; L is not more than the distance X of screw thread end point to the sealing surface circular arc, so that after screw thread machined, knife bar removed to process sealing surface with the fastest apart from feed.
Gang tool of the present utility model can be monoblock type, also can be combined type, to be fit to different processing needs.Described special-purpose blade can be a deburring blade, and specific Cutting blade for machining screw thread or sealing surface are processed special-purpose blade.
Compared with prior art, because screw thread processing and deburring or the processing of specific screw thread or sealing surface Processing realizes at same knife bar, has saved tool change time, thereby shortens processing rhythm, simultaneously convenient processing Adjust.
