Description
Technical field
The utility model relates to Gear Processing field, specifically refers to the fastener being provided with self-locking structure.
Background technology
In the processing technology of gear hobbing, Hobbing belongs to generating, the wheel and rack transmission that can will regard as without back lash.When gear hobbing rotates a circle, be equivalent to tooth bar and move a cutter tooth in normal direction, the continuous transmission of hobboing cutter, just as the tooth bar of an endless at continuous moving.When between hobboing cutter and gear hobbing base in strict accordance with gear when the gearratio positively engaging transmission of tooth bar, the envelope of cutter tooth on a series of position of hobboing cutter just defines the involute profile of workpiece.Along with the vertical feed of hobboing cutter, required involute profile can be gone out by rolling cut.
But in actual mechanical process, usually adopt two or plural tooth base carries out rolling cut, to improve working (machining) efficiency simultaneously.But the fixing impact being easily subject to many factors of gear ring, install as hobboing cutter and misalign, after hobboing cutter sharpening, the radial error of lip surface increases, and fixture produces runout etc., all can affect the machining accuracy of tooth base, increases the scrappage of tooth base.
Utility model content
The purpose of this utility model is to provide the fastener being provided with self-locking structure, facilitates the tightness of tooth base when rolling cut, and tooth base carries out trace adjustment, reaches the object improving machining accuracy.
The purpose of this utility model is achieved through the following technical solutions:
Be provided with the fastener of self-locking structure, comprise link and to be fixed on link and the back shaft that arranges of hollow, the outer wall of back shaft has been threaded wheel flange, the sidewall of back shaft offers two corresponding bellmouths arranged, all slide in two bellmouths and be provided with regulating block, the cross-sectional width of regulating block progressively increases progressively from the bottom to top; Rotating shaft is provided with in back shaft, one end of rotating shaft is stretched out outside back shaft free end, the other end of rotating shaft is arranged with cross section and is ellipticity and the castor that can act on regulating block, castor is provided with ratchet away from the end face of link, rotating shaft is provided with the stationary magazine creel with double-deck barrel by bearing holder (housing, cover), the outer barrel of stationary magazine creel offers strip gab, stationary magazine creel internal layer barrel is arranged with adjusting rod, adjusting rod is fixed with through strip gab and the pawl that can coordinate with ratchet.
When the utility model uses, then be first oppositely arranged by two tooth bases is set on back shaft, make it to be fixed two tooth bases by rotating wheel flange, until two tooth bases with the center of bellmouth for symmetric points, fasteningly be symmetricly set on back shaft, and the local of regulating block is outstanding and be placed between two tooth bases, link is then fixed on lathe, by the rolling cut operation of tooth base to complete the production and processing of gear hobbing; In use procedure, due to many factors, two the tooth bases be oppositely arranged there will be certain circular runout and cause its fixed position to offset, and namely need to finely tune tooth base.Rotating shaft, castor can be driven to rotate, and the cross section due to castor is ellipticity, thus in its rotation process, then the moving up and down while that two regulating blocks being driven to occur, and then realize the lifting of regulating block between two tooth bases.Particularly, when the longitudinal end of castor acts on regulating block, regulating block is then positioned at highest order place, now, regulating block utilizes the end contact of male cone (strobilus masculinus) and tooth base on its two side and produces opposing compression, fastening dynamics between two tooth bases is increased again, and then reduces the movement deviation of tooth base, reach the object improving gear hobbing process precision.When the rotation along with castor, when its minor axis end acts on regulating block, regulating block is positioned at lowest order place, now, spacing between two finished product gear hobbings reduces gradually, and correspondingly, the fastening dynamics between two finished product gear hobbings reduces gradually, manually can dismantle the gear hobbing of finished product fast, substantially increase the working (machining) efficiency of gear hobbing.
Due in the process of gear hobbing, two tooth bases can produce compared with the reaction force of great dynamics to regulating block, thus after the position adjustments of regulating block is good, also need this position to lock, avoid regulating block move down and affect the fixation to two tooth bases.In the utility model, be connected, driven by adjusting rod near the direction of link by cylinder or the output of hydraulic cylinder with the end of adjusting rod, like this, pawl then can slowly be inserted in ratchet to realize the braking to castor.Now, even if two tooth bases cause the extruding of larger intensity to regulating block, castor also can not rotate and affect the position of regulating block.So, the utility model reliability of operation is substantially increased.
For ease of rotating shaft and control and regulation block displacement, further, the end that described back shaft is stretched out in affiliated rotating shaft is provided with rotating disc, and rotating disc is provided with graduation apparatus.Because castor is positioned at back shaft, and be unfavorable for observing the matching relationship of itself and regulating block, thus the mark corresponding with position relationship can be engraved on the rotating pan, so, the efficient fine setting to regulating block can be convenient to, make the lifting of regulating block keep stable, and then more flexibly the fastening dynamics between two tooth bases is regulated, ensure the machining accuracy of tooth base.
For realizing the transmission of rotating shaft to castor, further, the junction of described castor and described rotating shaft is provided with flat key.
For avoid regulating block with the engagement process of castor in depart from castor, further, the anchor ring of described castor is provided with sliding tray, the bottom of two described regulating blocks is all positioned at sliding tray.
For the mating shapes with regulating block, further, radially successively decrease along described back shaft in the aperture of described bellmouth.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model passes through rotating shaft, castor can be driven to rotate, and the cross section due to castor is ellipticity, thus in its rotation process, the moving up and down while that two regulating blocks then being driven to occur, and then realize the lifting of regulating block between two tooth bases.
2, in the utility model, be connected, driven by adjusting rod near the direction of link by cylinder or the output of hydraulic cylinder with the end of adjusting rod, like this, pawl then can slowly be inserted in ratchet to realize the braking to castor.Now, even if two tooth bases cause the extruding of larger intensity to regulating block, castor also can not rotate and affect the position of regulating block.So, the utility model reliability of operation is substantially increased.
3, because castor is positioned at back shaft, and be unfavorable for observing the matching relationship of itself and regulating block, thus by the setting of rotating disc and graduation apparatus, the efficient fine setting to regulating block can be convenient to, the lifting of regulating block is made to keep stable, and then more flexibly the fastening dynamics between two tooth bases is regulated, ensure the machining accuracy of tooth base.
