Description
Technical field
The utility model is applicable to gear shaft field of fixtures, refers more particularly to a kind of gear grinding clamp for output shaft of gear-box.
Background technology
Automobile gearbox is the driving conditions owing to will adapt to often change, makes engine (power is higher, oil consumption is lower) work under favourable operating mode simultaneously, thus arranges in transmission system.Its function is to change gearratio, expand the excursion of driving wheel torque and rotational speed, to adapt to the driving conditions of often change, under making engine be operated in the constant situation of hand engine rotation under the operating mode of favourable (speed is higher and oil consumption is lower), be that automobile can fall back traveling simultaneously; Utilize neutral, interrupt power transmission, can to start with engine, idling, and be convenient to shifting of transmission or carry out Power output.The power exported is sent to automobile every field through gearbox output gear shaft thus realizes the change on car speed and direction.So the precision of gearbox output gear shaft wants high, otherwise affect power transmission performance.
When in the prior art grinding being carried out to output gear shaft, need use one workpiece and lathe can be carried out the fixture be connected, as dabber clamp, the fixture of butterfly spring sheet is housed, chuck clamps etc.Chuck clamps calibration of workpieces is complicated, and efficiency is low; The fixture that butterfly spring sheet is housed is applicable to the less gear shaft of specification, and dabber clamp precision is lower, is just difficult to reach for the gear shaft grinding of required precision more than 6 grades.
Utility model content
The purpose of this utility model solves the technical problem to the location complexity of gear shaft in prior art.
In order to solve the problems of the technologies described above, the utility model provides a kind of gear grinding clamp for output shaft of gear-box, comprise the arbor be connected with lathe, one end of arbor and lathe are taper fit, one end that arbor is used for fixing output shaft is multistage multidiameter, one end of this multistage multidiameter is provided with the locating centre for connecting output shaft, the multidiameter of wherein minimum diameter is arranged with the resilient sleeve for fixing output shaft, the tapered structure of the outer surface of resilient sleeve near one end of output shaft, resilient sleeve outer surface is arranged with adapter sleeve, described adapter sleeve is provided with boss near one end of lathe, its other end is the pyramidal structure matched with resilient sleeve, the multidiameter of maximum gauge has been threaded locking nut, locking nut is provided with and can realizes the lock piece of clamping with the boss of adapter sleeve, arbor is also provided with positioner, this positioner comprises the locating hole be located on arbor and the alignment pin be slidably connected on locking nut, be fixed in locating hole by alignment pin, locking nut is fixed on arbor.
Adopt technique scheme, during use, by one end of arbor and lathe taper fit, screw locking nut, locking nut is moved right, because locking nut is set on adapter sleeve, adapter sleeve and arbor are matched in clearance, and the front end of adapter sleeve and resilient sleeve is taper fit, so adapter sleeve is slowly replied to the right along with the motion of locking nut, the active force that adapter sleeve front-end-cone applies in the face of resilient sleeve reduces, and resilient sleeve expands outwardly, now, gear bush to be ground is located on the positioning cone of arbor.Screw locking nut again to left movement, pull adapter sleeve, fastening casing pressure draws resilient sleeve, and resilient sleeve is inwardly shunk thus gripping pinion.In order to avoid carrying out in the process of roll flute processing to output shaft, arbor produces vibration, thus locking nut is slided to the right along its thread path, reduce adapter sleeve and cannot clamp output shaft to the tightening force of resilient sleeve, so, arbor offers locating hole and the alignment pin that is slidably connected on locking nut, extend in locating hole by alignment pin, even if there is larger vibration, each parts also can not be made to produce displacement.Therefore only need to select stubborn locking nut just can complete clamping to gear shaft and dismounting, convenient and simple.In addition arbor and lathe adopt taper fit, easy accessibility, and the accuracy of gear after grinding can reach more than 6 grades.
Further, the front end of described resilient sleeve and adapter sleeve is taper fit.Be convenient to adapter sleeve better press and draw resilient sleeve, thus better gripping pinion.
Further, described adapter sleeve is rubber layer, makes adapter sleeve have better recovery.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model for the gear grinding clamp of output shaft of gear-box.
Detailed description of the invention
Reference numeral during accompanying drawing illustrates is: arbor 1, locating centre 2, resilient sleeve 3, adapter sleeve 4, boss 5, locking nut 6, lock piece 7, alignment pin 8, output shaft 9.
As shown in Figure 1, the technical program provides a kind of gear grinding clamp for output shaft of gear-box 9, comprises the arbor 1 be connected with lathe, and the left end of arbor 1 and lathe are taper fit.Arbor 1 is multistage multidiameter for one end of fixing output shaft 9, and it is followed successively by locating centre 2, first multidiameter, the second multidiameter and the 3rd multidiameter for connecting output shaft 9 from right to left.Wherein the first multidiameter is arranged with the resilient sleeve 3 for fixing output shaft 9, the outer surface of resilient sleeve 3 right-hand member is in the pyramidal structure had a down dip to the right.Resilient sleeve 3 and the second multidiameter are arranged with adapter sleeve 4, and the left end of described adapter sleeve 4 is connected with boss 5, and its other end is the pyramidal structure matched with resilient sleeve 3.3rd multidiameter has been threaded locking nut 6, and locking nut 6 is provided with and can realizes the lock piece 7 of clamping with the boss 5 of adapter sleeve 4.Arbor 1 is also provided with positioner, and this positioner comprises the locating hole be located on arbor 1 and the alignment pin 8 be vertically slidably connected on locking nut 6, is extend in locating hole by alignment pin 8, thus realizes locking nut 6 to be fixed on arbor 1.
During use, by the left end of arbor 1 and lathe taper fit, screw locking nut 6, locking nut 6 is moved right, blocked because adapter sleeve 4 overlaps the nut 6 that is locked, adapter sleeve 4 and arbor 1 are matched in clearance, and the front end of adapter sleeve 4 and resilient sleeve 3 is taper fit, so adapter sleeve 4 is slowly replied to the right along with the motion of locking nut 6, the active force that adapter sleeve 4 front-end-cone applies in the face of resilient sleeve 3 reduces, resilient sleeve 3 expands outwardly, and now, is set on the locating centre 2 of arbor 1 by output shaft 9 to be ground.Screw locking nut 6 again to left movement, pull adapter sleeve 4, adapter sleeve 4 pressure draws resilient sleeve 3, resilient sleeve 3 is inwardly shunk thus clamping output shaft 9.In addition, in order to avoid carrying out in the process of roll flute processing to output shaft 9, arbor 1 produces vibration, thus locking nut 6 is slided to the right along its thread path, reduce the tightening force of adapter sleeve 4 pairs of resilient sleeve 3 and output shaft 9 cannot be clamped, so, arbor 1 offers locating hole and the alignment pin 8 that is slidably connected on locking nut 6, extend in locating hole by alignment pin 8, even if there is larger vibration, each parts also can not be made to produce displacement.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
