Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] The multi-cylinder crankshaft static balance testing device S includes a horizontally arranged base plate 2. A pair of guide rails 3 are provided on the upper surface of the base plate 2. A first slider group 41 and a second slider group 42 are provided between the guide rails 3. The first slider group 41 is provided with a separable first support seat 61, and the second slider group 42 is provided with a separable second support seat 62. A detachable first roller base 71 is provided above the first support seat 61, and a detachable second roller base 72 is provided above the second support seat 62. A pair of first rollers 81 are provided on the first roller base 71, and a pair of second rollers 82 are provided on the second roller base 72. A first rocker screw assembly 51 and a second rocker screw assembly 52 are also provided on the upper surface of the base plate 2. The first rocker screw assembly 51 and the second rocker screw assembly 52 are both located between the guide rails 3, and the first rocker screw assembly 51 drives the first support seat 61, and the second rocker screw assembly 52 drives the second support seat 62.

[0021] The bottom of the first support base 61 is provided with a first screw hole 611, the bottom of the second support base 62 is provided with a second screw hole 621, the first rocker screw assembly 51 includes a first adjusting screw 511, the first adjusting screw 511 passes through the first screw hole 611, and the second rocker screw assembly 52 includes a second adjusting screw 521, the second adjusting screw 521 passes through the second screw hole 621.

[0022] In addition, adjustable foot supports 21 are provided at the four corners of the bottom of the base plate 2.

[0023] In addition, a vertically arranged upright plate 9 is provided on one side of the base plate 2.

[0024] The following describes the working principle of this multi-cylinder crankshaft static balance testing device, including the following steps:

[0025] Step S1: As Figure 4 and Figure 5 As shown, adjust the height of the four adjustable feet 21 and verify the base plate with a level to ensure that the base plate 2 remains level. Based on the distance between the two ends of the crankshaft A, the distance between the roller bases is adjusted through the first rocker screw assembly 51 and the second rocker screw assembly 52 to ensure that the two ends of the crankshaft A are exactly in the V-shaped position of the two sets of rollers.

[0026] Step S2: Place the two shaft diameters a-1 and a-2 on crankshaft A on the V-shaped positions formed by the first roller 81 and the second roller 82 respectively, and then fine-tune the first rocker screw assembly 51 and the second rocker screw assembly 52 again so that the first roller base 71 and the second roller base 72 move to the appropriate position. Finally, lock the first rocker screw assembly 51 and the second rocker screw assembly 52.

[0027] Step S3: Move crankshaft A and let it rotate along the axis. Observe the state of the crankshaft after it stops rotating. If it can stop slowly and remain without turning back or wobbling, it means that the static balance of the crankshaft is qualified. If the crankshaft turns back or wobbles back and forth when it stops, the static balance of the crankshaft is not qualified.

[0028] This multi-cylinder crankshaft static balance testing device is simple to operate, easy to load and unload parts, and accurate in measurement. It can realize the static balance inspection of multi-cylinder crankshaft products, solve the problem of inaccurate static balance testing of multi-cylinder motorcycle crankshafts, and ensure the stability and reliability of the crankshaft during operation.

[0029] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
