Description
Technical field
The utility model relates to the experimental provision technical field, especially relates to a kind of magnesium alloy hub dynamic bending fatigue detection stand.
Background technology
Magnesium alloy hub is to realize the light-weighted important directions of wheel hub at present.But as the product of prematurity still, each improvement all need in time be carried out performance test for it.Wherein, the dynamic bending fatigue of magnesium alloy hub being detected, is a very important job.But still none is simple and practical at present, and easy and simple to handle, accuracy is high, lower-cost pick-up unit.
The utility model content
The purpose of this utility model provides a kind of magnesium alloy hub dynamic bending fatigue detection stand, and it has simple and practical, and characteristics simple to operate, lower-cost.Further, it has the high characteristics of accuracy.
The technical scheme that the utility model adopts is: magnesium alloy hub dynamic bending fatigue detection stand, dynamic bending fatigue for detection of magnesium alloy hub, this monitor station comprises rotating disk, what described magnesium alloy hub was coaxial is fixed on this rotating disk, in the core wheel endoporus of this magnesium alloy hub interference fit be inserted with load arm, the right-hand member of this load arm is provided with bearing, the external stability of this bearing is useful on the hanging ring that hangs weight, simultaneously, this rotating disk is fixed on the lathe.
Be provided with step around load arm on the described rotating disk, the core wheel of this step and magnesium alloy hub matches.
Described load arm is equipped with for the 45# steel.
The wheel rim of described magnesium alloy hub is fixed on the rotating disk by at least 3 pressing plates.
Described pressing plate by bolt on pressing plate.
Described bearing is fixed in the right-hand member of this load arm by shaft block ring.
The utility model is compared the advantage that has with prior art: 1, simple and practical, and simple to operate, cost is lower.Magnesium alloy hub dynamic bending fatigue detection stand used unit of the present utility model is less, in use, provide rotary power by lathe, hang the weight of Different Weight at the right-hand member of load arm, can the dynamic bending fatigue of this magnesium alloy hub be detected, comparatively simple.Simultaneously because this detections gantry components is easy to get, during use by means of existing equipments such as lathes, thereby the cost reduction.2, accuracy height.Rotating disk is provided with step, thereby can realize the coaxial of rotating disk, magnesium alloy hub, load arm, and load arm adopts the 4545# steel, has guaranteed rigidity and the intensity of load arm.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is that the master of the application state of embodiment of the present utility model looks cut-open view.
Among the figure: 1, magnesium alloy hub; 2, load arm; 3, hanging ring; 4, bearing; 5, shaft block ring; 6, bolt; 7, pressing plate; 8, rotating disk, 81, step.
Embodiment
Embodiment, see shown in Figure 1: magnesium alloy hub dynamic bending fatigue detection stand, for detection of the dynamic bending fatigue of magnesium alloy hub 1.This monitor station comprises rotating disk 8, this magnesium alloy hub 1 coaxial being fixed on this rotating disk 8.That is, this magnesium alloy hub 1 can be in company with rotating disk 8 coaxial and synchronous rotations.In the core wheel endoporus of this magnesium alloy hub 1 interference fit be inserted with load arm 2, the right-hand member of this load arm 2 is provided with bearing 4, the external stability of this bearing 4 is useful on the hanging ring 3 that hangs weight.Certainly, hanging ring 3 can also be similar devices such as hook.That is, weight hangs on the hanging ring 3, can be all the time the right-hand member of load arm 2 be imposed downward power.In order to utilize existing equipment, this rotating disk 8 is fixed on the lathe.That is, the rotation that rotates to be rotating disk 8 of lathe provides power.Like this, adjust weight of heavy, start lathe, can implement the dynamic bending fatigue detection to magnesium alloy hub.Simultaneously, this magnesium alloy hub dynamic bending fatigue detection stand used unit is few, simple to operate, and preparation and use cost are all lower.
Optimize:
Be provided with step 81 around load arm 2 on this rotating disk 8, the core wheel of this step 81 and magnesium alloy hub 1 matches.That is, the outer ledge of these step 81 chucking core wheels, thus wheel hub is implemented the location, guaranteed the coaxial of this magnesium alloy hub 1 and rotating disk 8 and load arm 2.This load arm 2 can take the 45# steel to be equipped with the best incorporated modulation treatment.Like this, guaranteed that load arm 2 has enough rigidity and intensity.These measures have all guaranteed to detect the accuracy of data.
The wheel rim of this magnesium alloy hub 1 can be fixed on the rotating disk 8 by at least 3 pressing plates 7, and this pressing plate 7 can be fixed on the pressing plate 7 by bolt 6.Like this, be convenient to the loading and unloading of this magnesium alloy hub 1.
This bearing 4 can be fixed in the right-hand member of this load arm 2 by shaft block ring 5.Like this, be convenient to the loading and unloading of bearing 4.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
