Description
Technical field
The utility model relates to synchronized processing technique field, is specifically related to a kind of synchronized and engages inserting internal tooth fixed mechanism.
Background technology
Because transmission input shaft and engine output shaft rotate with respective speed, during conversion gear, " synchronously " problem can be there is.Two different gears of rotary speed engage by force and impact will inevitably occur, and damage gear.Therefore, the gear shift of old-fashioned speed changer will adopt the mode of " bipod clutch ", upshift neutral position stop a moment (but clutch need lift, object is to allow clutch disc also want and flywheel synchronization, just rotating speed must unanimously can engage a gear smoothly, if it is slow to shift gears, rotating speed falls idling, also cannot hang into), downshift will at neutral position (keep clutch lift) open out simultaneously, to reduce the speed discrepancy of gear.But this operates more complicated, be difficult to grasp accurately.Therefore designer creates " synchronized ", makes to reach consistent rotating speed and engage smoothly by meshed gears by synchronized.
Synchronized, it is primarily of compositions such as clutch collar, synchronous lock rings, and its feature relies on rubbing action to realize synchronously.
The gear ring of clutch collar, synchronous lock ring and gear to be joined all has chamfering (angle of lock), and the inner conical surface of synchronous lock ring contacts to produce with gear-wheel gear-ring male cone (strobilus masculinus) to be joined and rubs.Suitable selection done by angle of lock and the conical surface when designing, conical surface friction makes tooth cover to be engaged synchronous rapidly with gear ring, can produce again a kind of locking effect simultaneously, prevent gear from engaging at advanced in unison row.
After synchronous lock ring inner conical surface contacts with gear-wheel gear-ring male cone (strobilus masculinus) to be joined, (or rising) is reduced rapidly to equal with synchronous lock ring rotating speed at the effect lower gear rotating speed of moment of friction, both synchronous rotaries, gear is zero relative to the rotating speed of synchronous lock ring, thus moment of inertia also disappears simultaneously, at this moment under the promotion of active force, clutch collar engages with synchrolock annular gear in the clear, and engage with the gear ring of gear to be joined further and complete gearshift procedure, at present when processing clutch collar endoporus spline tooth, inventor encounters a difficult problem, existing clutch collar fixture cannot firmly fix clutch collar fast, the Gear Shaping process of clutch collar is consuming time long in the fixed engagement cover stage, reduce clutch collar endoporus spline tooth working (machining) efficiency.
Utility model content
The utility model is intended to provide a kind of synchronized to engage inserting internal tooth fixed mechanism, to improve clutch collar endoporus spline tooth working (machining) efficiency.
Synchronized in this programme engages inserting internal tooth fixed mechanism, comprises disk body, pull bar, expansion block, spring and splicing sleeve; Disk body and lathe removably connect, disk body central protuberance is formed the boss of clutch collar workpiece spindle to guiding, splicing sleeve upper end circumference locating engagement cover workpiece, splicing sleeve lower end is detachably connected on disk body, pull bar is arranged in splicing sleeve endoporus and is axially slidably connected with disk body along disk body, pull bar working end is provided with pull head, pull head is back taper, expansion block is at least two pieces and circumference is close to pull head, it is the conical surface mated with back taper pull head inside expansion block, be provided with groove outside expansion block, spring fixes in a groove, and pull bar and disk body junction are also provided with rubber seal.
The advantage of this programme is: comprise disk body, pull bar, expansion block, spring and splicing sleeve, disk body and lathe removably connect, disk body central protuberance is formed the boss of clutch collar workpiece spindle to guiding, and boss can play guide effect to clutch collar workpiece, splicing sleeve upper end circumference locating engagement cover workpiece, the end face of synchronized clutch collar workpiece can be against herein, thus carries out axial location, splicing sleeve lower end is detachably connected on disk body, pull bar is arranged in splicing sleeve endoporus and is axially slidably connected with disk body along disk body, pull bar working end is provided with pull head, pull head is back taper, expansion block is at least two pieces and circumference is close to pull head, it is the conical surface mated with back taper pull head inside expansion block, pull pull bar, expansion block outside motion swelling synchronized clutch collar workpiece can be made by pull head, groove is provided with outside expansion block, spring fixes in a groove, expansion block is made to be close to the pull head of pull bar all the time, also expansion block can be made to reset when pull bar resets simultaneously, thus easily take off synchronized clutch collar workpiece, pull bar and disk body junction are also provided with rubber seal, sealing ring not only prevents iron filings etc. from entering disk body and pull bar binding site but also can also play guide effect to pull bar.
During work, be placed on splicing sleeve by synchronized clutch collar workpiece and carry out end face location, then pull pull bar, pull head moves down, and moves on driving expansion block is reverse, thus swelling synchronized clutch collar workpiece, so can carry out Gear Shaping; After machining, only need reverse pushing drawing rod to reset, pull head moves, and expansion block is retracted for clearance under the action of the spring, and then unclamp synchronized clutch collar workpiece, so can take off synchronized clutch collar workpiece, this programme structure is simple, processing ease, can quick-clamping synchronized clutch collar workpiece, be convenient to carry out Gear Shaping fast, improve synchronized clutch collar inner hole of workpiece spline tooth working (machining) efficiency, reduce costs.
Further, splicing sleeve lower end is provided with boss, and boss circumference is evenly equipped with six screws, Stability Analysis of Structures, with disk body easy installation and removal.
Further, be connected by screw by finger setting between disk body and lathe, not only accurate positioning but also conveniently to install.
Further, disk body outer rim is connected by screw and is fixed with chip guard, prevent the iron filings produced in process from entering into axle and machine tool joints position, affect assembly precision.
Further, the drive division that pull bar comprises sliding part and is threaded with sliding part, pull head is positioned at sliding part upper end, facilitates installing/dismounting, it also avoid pull bar long be difficult to processing.
Further, pull head tapering is 1:3, can ensure that expansion block distance of outside movement under pull bar effect is enough to fix to clamp synchronized clutch collar workpiece.
