Shown in Figure 6, described flexible dynamic module is made up of turning axle 5a, back up pad 5b, axle four 5c, handwheel two 5d, gear seven 5e and gear eight 5f, turning axle 5a both ends are provided with spline, the hole of back up pad 5b is provided with the spline coordinated with turning axle 5a both ends, described turning axle 5a is fixed on the first bracing frame 1b, and turning axle 5a coordinates with the interporal lacuna of back up pad 5b; Handwheel two 5d is fixedly connected with axle four 5c, and axle four 5c coordinates with the interporal lacuna of back up pad 5b, and two ends are moved respectively by handwheel two 5d and nut restriction X-direction; Gear seven 5e, gear eight 5f are connected with axle four 5c key, and are fixed by spring collar; Flexible dynamic module can be the movement of Y worktable, module of rising and falling and clamp module by different gears meshing and provides power respectively; The flexible body of flexible dynamic module is present: the two ends of turning axle 5a have spline, back up pad 5b has the spline coordinated with turning axle 5a, when back up pad 5b is in turning axle 5a centre position, can rotate around it; When back up pad 5b rotates to around turning axle 5a the position that gear eight 5f can engage with gear two 2e, back up pad 5b is pulled to along X negative sense the position that gear eight 5f engages with gear two 2e, rotates handwheel two 5d and can provide power to the movement of Y worktable; Back up pad 5b is pushed into turning axle 5a centre position along X forward, rotary support plate 5b, when rotating to the position that gear seven 5e can engage with gear five 3c, back up pad 5b is pushed into along X forward the position that gear seven 5e engages with gear five 3c, rotation handwheel two 5d can be module of rising and falling provides power; To twice tire pressure monitoring, location-plate 2j is different from the distance of tire, therefore the distance of clamp module movement is different, to different distances, in order to realize pinching action, gear eight 5f must engage with gear six 4d, and now back up pad 5b can rotate to the gear eight 5f tooth matching angle different from gear six 4d around turning axle 5a centre position, thus realizes the transmission of power; Back up pad 5b, after turning axle 5a rotates to fixed position, by the spline fitted at spline and turning axle 5a two ends, thus overcomes the acting forces such as back up pad 5b gravity, and realizes not reciprocal rotation.
Shown in Figure 1, described supplementary module is made up of pressure transducer 6a and displacement transducer 6b, described pressure transducer 6a is fixed on the end of left and right fixture, and the fixed part of displacement transducer 6b is fixed on Y worktable 2b, and movable part is connected on left fixture 4a; To the tire of pressure abundance, when left and right fixture moves a certain distance, pressure transducer can show higher force value, reach a critical field, thus the pressure defining this tire is enough; On the contrary, when left and right fixture moves a certain distance, the force value of pressure transducer display is still lower, does not reach critical field, thus defines the insufficient pressure of this tire.
See shown in Fig. 1 to Fig. 8, the course of work of the present invention is as follows:
Under original state, XY worktable is in original state, and this device is pushed away this device along the axis direction of tire by staff, to location-plate 2j near tire, realizes the coarse positioning of location-plate 2j and tire.Rotate handwheel one 2i, realized the movement of X worktable by rocking bar 2h, slide block 2g, axle one 2c, mobile X worktable, to location-plate 2j to the diametric(al) of tire, so far then achieves the axial location of location-plate 2j and tire.Back up pad 5b is pushed into along X forward the position that gear seven 5e engages with gear five 3c, rotates handwheel two 5d, by engaging of gear seven 5e and gear five 3c, the transmission of axle two 3f, realizes the landing of left and right fixture.Handwheel two 5d is oppositely pulled to along X the position that gear eight 5f engages with gear two 2e, rotate handwheel two 5d, realize the movement of Y worktable 2b and the accurate position fixing process of location-plate 2j and tire, until location-plate 2j and tire are fitted completely, because location-plate 2j is fixed on Y worktable 2b, the angle that left and right fixture rotates is fixing, when location-plate 2j and tire are fitted completely, namely left and right fixture has rotated to the radial direction of tire, then achieves the accurate location of left and right fixture and tire to this.Back up pad 5b is rotated to around turning axle 5a the angle that gear eight 5f engages with gear six 4d; By rotating handwheel two 5d, by engaging of gear eight 5f and gear six 4d, realized reverse movement---the clamping movement of left and right fixture by axle three 4c with different rotation direction screw thread.Judge that whether tire pressure is enough by the comparison of the pressure transducer 6a in supplementary module and displacement transducer 6b: to the tire of pressure abundance, when left and right fixture moves a certain distance, pressure transducer 6a can show higher force value, reach a critical field, then the pressure defining this tire is enough; On the contrary, when left and right fixture moves a certain distance, the force value that pressure transducer 6a shows is still lower, does not reach critical field, then defines the insufficient pressure of this tire.
In order to safety and precision controlling, the rise process of left and right fixture is the inverse process of dropping process.When pressure detection completes, rotate backward handwheel two 5d, by engaging of gear eight 5f and gear six 4d, axle three 4c namely by having different rotation direction screw thread realizes the reverse movement of left and right fixture, realizes the relieving action of left and right fixture to tire; Around the position that turning axle 5a rotary support plate 5b engages to gear eight 5f with gear two 2e, rotate handwheel two 5d, realize the reverse movement of Y worktable 2b and location-plate 2j to tire away from process, to initial position; Handwheel two 5d is pushed into along X forward the position that gear seven 5e engages with gear five 3c, rotates handwheel two 5d, by engaging of gear seven 5e and gear five 3c, the transmission of axle two 3f, realizes the rise of left and right fixture.Finally rotate handwheel one 2i, realized the reverse movement of X worktable by rocking bar 2h, slide block 2g, axle one 2c and slider-crank mechanism, to initial position.
The foregoing is only preferred embodiment of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All any amendments made for the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
