Description
Technical field
The utility model relates to a kind of screw die, particularly relates to a kind of adjustable screw die.
Background technology
At present, the screw die on market is all seriation, attacks once the external screw thread of determining diameter and must useCorresponding screw die is processed with it. In reality productive life, the number of universal threaded specification reaches tenMultiple, the screw die specification of therefore using when tapping also just has kind more than ten. Because screw die specification is numerous,But general structure only has again one or two kind, the screw die that therefore production specification is numerous just seems loaded down with trivial details, unnecessary.In addition workman in the time of external threading, need to spend the much time in the screw die of numerous specifications, go to select suitableScrew die, has reduced operating efficiency, therefore needs to have a kind of adjustable screw die, has produced thus this patent.
Summary of the invention
The screw die that provides a kind of radial dimension adjustable is provided the purpose of this utility model, thereby with a plateTooth can be processed the external screw thread of a series of sizes.
The adjustable screw die that the utility model provides, comprise screw die body, bevel gear wheel, bevel pinion andTapping cutter pawl, is processed with equally distributed radial slot and radial hole on described screw die body, described auger toothWheel is installed in rotation in screw die body, and it is processed with flat thread with the one side that tapping cutter pawl contacts;Described tapping cutter pawl is arranged in the radial slot on screw die body, cutting edge and work piece on tapping cutter pawlContact, the one side contacting with bevel gear wheel on tapping cutter pawl is processed with flat thread, this flat threadEngage with the flat thread on tapping cutter pawl, in the time that bevel gear wheel rotates, by tapping cutter pawl and augerThe engagement of the flat thread on gear can make tapping cutter pawl radially groove move radially; Described bevel pinionEngage and be arranged on bevel gear wheel in the radial hole on screw die body, on the outside end face of bevel pinion, establishThere is spanner groove; On described screw die body and tapping cutter pawl be provided with graduation mark, for checking tapping cutter pawlDisplacement, and calculate the external thread diameter of processing.
Above-mentioned bevel pinion and tapping cutter pawl are three.
A screw die of the present utility model can be processed the external screw thread of a series of diameters, thereby can avoidProduce the screw die of numerous specifications, be also convenient to deposit and use screw die, can improve to a certain extent processingOperating efficiency when external screw thread.

Detailed description of the invention
As shown in Fig. 1～Fig. 7, the utility model comprises screw die body 1, tapping cutter pawl 2, conelet toothWheel 3 and bevel gear wheel 4, be processed with equally distributed three radial slots 101 and three on described screw die body 1Individual radial hole 102, be also provided with graduation mark 103 on the end face of screw die body 1, for checking tapping cutter pawlDisplacement, and calculate the external thread diameter of processing.
Described bevel gear wheel 4 is arranged in screw die body 1 also rotatable, bevel gear wheel 4 and tappingThe one side that cutter pawl 2 contacts is processed with flat thread (snail line). Described tapping cutter pawl 2 altogetherThree, be arranged in the radial slot 101 on screw die body 1, on tapping cutter pawl 2 with bevel gear wheel 4 phasesThe one side of contact is processed with flat thread 202, the plane spiral shell on this flat thread 202 and bevel gear wheel 4Line engagement, the cutting edge 201 on tapping cutter pawl 2 contacts with work piece, for threading, attacksThe other end of silk cutter pawl 2 is provided with groove 203, the graduation mark on this groove 203 and screw die body 1103 are positioned at the same side. Totally three of described bevel pinions 3, three bevel pinions 3 are arranged on respectively screw dieIn radial hole 102 on body 1, and engage the end that bevel pinion 3 is outside simultaneously with bevel gear wheel 4Face is provided with spanner groove 301. End cap 5 is arranged on one end of screw die body 1.
The utility model first allows first on groove 203 on tapping cutter pawl 2 and screw die body 1 while useIndividual graduation mark is concordant, and (occurrence can be in the time producing this screw die for diameter maximum that now can threadingRegulation). In the time need to processing the external screw thread of other diameters, on demand tapping cutter pawl 2 is moved to centerMoving, concrete displacement can be checked and be calculated by graduation mark 103. Suppose that the utility model can processMaximum external thread diameter be 30mm, the distance (lattice) of two grooves of arbitrary neighborhood in graduation mark 103For 0.5mm, if need to process the external screw thread that diameter is 20mm, tapping cutter pawl 2 need to inThe heart moves 10 lattice graduation marks.
The concrete steps that tapping cutter pawl 2 moves are: first spanner is inserted to the spanner groove on bevel pinion 3In 301, then pull spanner, because bevel pinion 3 engages with bevel gear wheel 4, therefore bevel gear wheel4 rotate, after bevel gear wheel 4 rotates, by the plane spiral shell on the flat thread on it and tapping cutter pawl 2The engagement of line 202 and three tapping cutter pawls 2 are moved to center simultaneously, thus required diameter can be processedExternal screw thread.
The above is only the good embodiment of the utility model, but protection domain of the present utility modelBe not limited to this, any improvement of carrying out based on scheme of the present utility model and design and replacement are all answeredBe encompassed in protection domain of the present utility model.
