Problems solved by technology
At present, the pull-out force is generally measured directly by using the dynamometer 4, and the randomness of manual operation has a great influence on the result.
At the same time, it is difficult to measure the press-fit force for the clamping of the wheel cover 2 and the rim 1

Embodiment Construction
[0037] refer to figure 2 , image 3 , the rim 14 as the measurement object is shown in the two figures at the same time. The measuring device of the clamping force of the wheel cover and the rim of the present embodiment includes: a stand bracket, a force measuring rod 10, a dynamometer 12, a hook 13 and Figure 8 and Figure 9 The stop lever 17 shown in. The bench support has a base plate 5, an opposite first upright 6 and a second upright 7 fixed on the base 5, a cross bar fixed between the first upright 6 and the second upright 7 and positioned above the base 5 9. In this embodiment, both the first upright rod 6 and the second upright rod 7 are in the form of an assembly composed of a plurality of rods, and these rods form a stable triangular shape. Both the first upright bar 6 and the second upright bar 7 are provided with a bar locking slot 8 . In fact, the bottom plate 5 can also be a rod or a plate, or directly use the ground or the table as the bottom plate 5, a...

The invention provides a measuring device for the clamping force between a wheel cover and a rim, comprising: a stand bracket, the stand bracket has a bottom plate, a pair of opposite upright rods fixed on the bottom plate, fixed on the upright a crossbar between the rods and above said base plate; a force measuring rod having an external thread which passes through said crossbar and threads with an adjusting nut placed on said crossbar cooperation; a dynamometer, the dynamometer is connected to the force measuring rod; a hook, the hook can be hung on the dynamometer; a stop bar, the stop bar is positioned on the vertical pole. The invention also provides a method for measuring the pull-out force and the press-in force of the wheel cover and the rim by using the above-mentioned measuring device. The invention has the advantages of being more accurate and capable of measuring the pull-out force and the press-in force with a set of devices.
Description
technical field [0001] The invention relates to the field of measurement, in particular to a measuring device and a measuring method for the engagement force between a wheel cover and a wheel rim. Background technique [0002] During the design process of the snap-in wheel cover, the snap-in force between the wheel cover and the rim is one of the important indicators of the wheel cover design. The clamping force specifically includes the wheel cover press-in force and the wheel cover pull-out force. The pressing force judges the operation convenience of installing the wheel cover on the rim, and the pull-out force judges the reliability of the connection between the wheel cover and the rim. At the beginning of the design, the design software is usually used for force analysis to obtain important parameters such as the deformation of the wheel cover and the size of the claw of the wheel cover. After the design is completed, the wheel cover needs to be tested on a bench to v...
