Abstract
The present invention relates to a jumping quantity measuring head for a wheel type dial test indicator, which is mainly composed of a wheel shaft 1, a shim 2, a rolling bearing 3, a coupling rod 4, a locking ring 5, a screw nut 6 and a spring 8. The present invention has the key points that the rolling bearing 3 is arranged in a groove at the lower end of the coupling rod 4 by the wheel shaft 1; the upper end of the coupling rod 4 is provided with an inner cone hole, and the locking ring 5 which is matched with the inner cone hole of the coupling rod 4 is put into the hole; the lower end of the locking ring 5 is provided with the spring 8, and the upper end is limited by the screw nut 6 which is arranged on the coupling rod 4; before the detection is carried out, a measuring rod of the dial test indicator 7 passes through the screw nut 6 and is inserted into the centre hole of the locking ring 5. The present invention expands the measurement ranges, measures the smooth surface and the surface which has large friction resistance or is provided with grooves, and solves the problem of the measurement of the assembly radial direction and the end face jumping of motorcycle wheels. The present invention has the advantages of simple structure, simple operation and low manufacture cost.
Description
Technical field
The present invention relates to a kind of testing tool, especially a kind of be used to detect the motorcycle wheel assembly radially with the wheeled dial gauge jerk value detection head of face runout amount.
Background technology
At present, the dial gauge gauge head is a steel ball, and it is installed in the sounding rod lower end of dial gauge, contacts with measured surface by steel ball, and the dial gauge pointer offset is the jerk value of measured surface, and it is mainly used in detects smooth measured surface.For detecting the big or fluted measured surface of frictional resistance, because steel ball is that to be directly installed on the sounding rod lower end of dial gauge and steel ball and measured surface surface of contact less, when steel ball when measured surface in rotating contacts, whole gauge outfit will be rocked, can't detect, when particularly detecting rubber and fluted bike wheel, since steel ball when contacting with bike wheel frictional resistance greatly and contact area less again, wheel makes the displacement of whole gauge outfit in measuring process, can't realize at all to the motorcycle wheel assembly radially with the detection of face runout amount.
Summary of the invention
The purpose of this invention is to provide a kind of wheeled dial gauge jerk value detection head that cooperates dial gauge to use, this detection head can be realized the big or fluted measured surface of frictional resistance is detected.
Concrete scheme of the present invention is: a kind of wheeled dial gauge jerk value detection head, it is characterized in that: described detection head is made up of wheel shaft, rolling bearing, pitman shaft, retaining ring, nut, spring, wherein in the groove of pitman shaft lower end, rolling bearing is installed by wheel shaft, upper end at pitman shaft is provided with internal taper hole, be placed with the retaining ring that is complementary with the pitman shaft internal taper hole in this hole, the retaining ring lower end is equipped with spring, and the upper end is spacing by the nut that is installed on the pitman shaft.
Described retaining ring leaves the gap by the 3 lobe arc latch segments cone structure that to surround a center be through hole between each latch segment.
This programme is by being provided with rolling bearing in the fluting of the lower end of pitman shaft, adopting rolling bearing to roll with measured surface contacts, thereby increased the stability of contact area and this device, can not be shifted when detecting the big or fluted surface of frictional resistance, guarantee the good detection precision with the present invention that applies.Retaining ring is surrounded by 3 lobe arc latch segments, leaves the gap between each latch segment, can allow retaining ring move the interior circle make retaining ring downward or upward under the effect of nut and spring and dwindle or amplify, and makes things convenient for the insertion of dial gauge sounding rod to fix or extract.
Advantage of the present invention is: 1, enlarged measurement range, not only can be to smooth surface, but also can measure the big or fluted surface of frictional resistance; 2, solved to the motorcycle wheel assembly radially with the measurement of face runout; 3, simple in structure, simple to operate, cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the present invention when being inserted with dial gauge 7;
Fig. 2 is the vertical view of retaining ring 5 among the present invention.
Embodiment
Below in conjunction with description of drawings embodiment is further described
See Fig. 1, Fig. 2 as can be known: the present invention mainly is made up of wheel shaft 1, pad 2, rolling bearing 3, pitman shaft 4, retaining ring 5, nut 6, spring 8, its invention main points are: by wheel shaft 1 rolling bearing 3 is installed in the groove of pitman shaft 4 lower ends, upper end at pitman shaft 4 is provided with internal taper hole, be placed with the retaining ring 5 that is complementary with pitman shaft 4 internal taper holes in this hole, retaining ring 5 lower ends are equipped with spring 8, and the upper end is spacing by the nut 6 that is installed on the pitman shaft 4.Before detecting, the sounding rod of dial gauge 7 is passed nut 6 insert in retaining rings 5 center pits.
See that Fig. 2 as can be known: retaining ring 5 leaves the gap by 3 lobe arc latch segments 9 cone structure that to surround a center be through hole between each latch segment.When nut 6 was twisted downwards, 3 lobe arc latch segments 9 moved down simultaneously, the gap smaller between each latch segment, and the cone through hole that surrounds dwindles, and then with the sounding rod chucking of the dial gauge 7 that inserts; When nut 6 was upwards twisted, 3 lobe arc latch segments 9 moved up under the effect of spring 8 simultaneously, and it is big that the gap between each latch segment becomes, and the cone through hole that surrounds amplifies, and the sounding rod of dial gauge 7 can be extracted in retaining ring 5.
See that Fig. 1 as can be known: rolling bearing 3 contacts with pitman shaft 4 through pad 2.
See that Fig. 1 also as can be known: described rolling bearing 3 is the bearing with two-sided dust cap.
Principle of work of the present invention is: on move nut 6 up to the sounding rod diameter of retaining ring 5 endoporus greater than dial gauge 7, insert the sounding rod of dial gauge 7 this moment, moving down nut 6 promotion retaining rings 5 moves down, the endoporus of retaining ring 5 is dwindled, sounding rod up to dial gauge 7 can not be extracted, dial gauge 7 can be contained in the magnetic dial gauge frame, rolling bearing 3 is contacted with the wheel tyre outer ring, rotating-wheel, at this moment rolling bearing 3 is done rolling with wheel tyre, dial gauge beat of pointer amount is the wheel tyre radial beat eccentricity, when of the present invention, can unscrew nut 6, retaining ring 5 is moved on automatic under the effect of lower springs 8, endoporus is magnified, take off wheeled dial gauge, dial gauge returns to original state.
