Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model Embodiment, those of ordinary skill in the art's every other embodiment obtained, fall within the protection scope of the utility model.

The utility model is present applicant based on the fact that and innovation and creation made by discovery.

The method of the general main tooth ring flange bounce of automobile factory's detection drive axle is that the dial indicator measuring head with magnetic support is placed on always Beat region is surveyed at main tooth ring flange, rotates ring flange with hand to measure the bounce of the main tooth ring flange of drive axle.With industry Technology development and to the high request of product quality, a kind of new measurement method start to be attempted and used by automobile factory, i.e., from driving Bridge two sides drive driving gear ring flange by the transmission chain of the compositions such as inner shaft, differential mechanism, driven gear and driving gear Bounce is to reach the measurement to the bounce of assembly main tooth ring flange, but existing driving device technical performance is poor, and production efficiency is low, Deviation is big, causes measurement result inaccurate, driving spline rocking handle easy hurt assembly differential mechanism or axle-shaft oil seal when entering or exiting, The requirement of client or automobile factory is not achieved, is not suitable for existing production process.

Existing hand driving device, as shown in Figure 1, hand driving device includes splined shaft 210 and crank 220, Its structure is that driving shaft head is splined shaft, and tail portion is made into crank form, and drive shaft is put in assembly inner shaft or half by manpower Shaft gear internal spline interconnecting piece 300, the in a manual manner main tooth ring flange rotation of drive assembly, is jumped with reaching the main tooth ring flange of measurement Dynamic purpose.The apparatus structure is simple, easily realizes, at low cost, but the device technique performance is poor, production efficiency is low, and hand-held Easy hurt assembly differential mechanism or axle-shaft oil seal, the rare use in advance of this device are not achieved when driving the entrance of spline rocking handle or exiting The requirement of client or automobile factory is not suitable for existing production process.

There are also a kind of automatic drives, as shown in Fig. 2, automatic drive includes, driving splined shaft 230, servo electricity Machine 240, adjustment base 250, cylinder 260 are driven driving splined shaft 230 by servo motor 240, pass through adjustment base 250 The position of servo motor 240 is adjusted, drives adjustment base 250 mobile by cylinder 260.Splined shaft in driving device is Rigid unitary axis is connected directly with the axis of servo motor, and splined shaft is protruded into drive axle internal spline connecting portion by cylinder, starting Servo motor drives splined shaft rotation, moves main tooth ring flange by drive axle internal drive subband and rotates, to start main tooth flange The measurement of disk.The advantages of this device is: splined actuating shaft enters, rotates and exits for motor-driven completion, advanced in performance, high-efficient. The disadvantage is that: due to half axle assembly of main reducing gear band of front driving axle, it can be used to the surface positioned when surveying the bounce of main tooth ring flange All be black skin (undressed), such as axle tube outer round surface and final drive casing outer surface, therefore the center of axle tube or Differential axle bearing bore centre-height error can change a lot with the difference of each measuring piece, and the height of motor shaft is missed Difference is fixed and invariable, and motor-driven splined shaft hardly enters drive axle internal splines in this state, even if entering Assembly internal splines structure also can be excessive because of the coaxiality error of splined shaft and drive axle internal spline, causes the vibration during driving It moves and influences measurement accuracy.

Based on this, present inventor obtains following innovation and creation by studying for a long period of time and finding.

The driving device 100 according to the utility model embodiment is specifically described with reference to the accompanying drawing.
