Example 1:

as shown in fig. 1 and 2, the invention provides a measuring device for a special-shaped spring of an automobile shock absorber, which comprises a measuring base 1, wherein the base 1 is provided with a fixing device for fixing the special-shaped spring, the base 1 is respectively provided with a vertical steel plate ruler and a horizontal steel plate ruler, the vertical steel plate ruler is used for measuring the total outer diameter of the special-shaped spring, the horizontal steel plate ruler is used for measuring the length of the special-shaped spring, two ends of the base 1 are provided with upright posts 3, and a profile gauge 2 is slidably mounted on the upright posts 3, and the profile gauge 2 comprises a bracket 201 with scales and a shape taking sheet 202. The profile gauge 2 is used to measure the pitch dimension and the respective outer diameter dimension of a lower spring. The base 1 is provided with a horizontal slideway 5 and a vertical slideway, the vertical slideway is arranged in an upright post 3 and is used for sliding a contour gauge 2, two ends of the contour gauge 2 are provided with fixing plates 203, the fixing plates 203 are fixedly connected with a first sliding block 6, and the other end of the first sliding block 6, which is connected with the fixing plates 203, is arranged in the vertical slideway. The horizontal sliding way 5 is used for sliding of the fixing device. The fixing device is a push plate 4, the push plate 4 is connected with a second sliding block, and the second sliding block is matched with a horizontal sliding way 5, so that the push plate 4 can horizontally slide. The upper end of the push plate 4 is provided with a U-shaped groove 401 for the profile gauge 2 to pass through when sliding.

The horizontal steel plate ruler is arranged beside the base 1, and a zero initial point of the horizontal steel plate ruler is in a straight line with a plane in contact with the special-shaped spring. The vertical steel plate ruler is installed on the upright post 3 which is vertically arranged, and the zero initial point of the vertical steel plate ruler is on the same horizontal plane with the contact surface for placing the special-shaped spring.

The invention also provides a measuring method applied to the measuring device, the special-shaped spring is placed on the measuring device and is fixed by the fixing device, and then the full length size C0 of the special-shaped spring is measured by the horizontal steel plate ruler.

The first sliding block 6 is slid to drive the outline gauge 2, so that the bottom end of the support 201 is stopped to the highest point of the special-shaped spring, and the vertical steel plate ruler is used for measuring the maximum outer diameter H0 of the special-shaped spring.

The contour gauge 2 presents each excircle contour and each horizontal wave peak point of the special-shaped spring, and the lengths of all the wave peak points are measured, so that different pitch sizes C1, C2, C3 and C4 of the special-shaped spring can be obtained; and measuring the height difference of all the wave crests to obtain the different outer diameter size differences H1, H2, H3 and H4 of the special-shaped spring.

And finally, subtracting the difference between the maximum outer diameter and the outer diameter to obtain the sizes of the special-shaped springs with different outer diameters.

As shown in figures 1 and 2, when the special-shaped spring pressing device is used, firstly, the special-shaped spring is placed on the horizontal slide rail 5, then the push plate 4 is pushed to move leftwards, so that the special-shaped spring is stable, because the plane contacted with the left end of the special-shaped spring and the zero position of the horizontal steel plate ruler are positioned on the same straight line, the right end of the special-shaped spring is contacted with the push plate 4, and the number of the contact position of the left end of the push plate 4 and the horizontal steel plate ruler is observed, so that the full length size C0 of the special-shaped spring can be obtained.

Then, the first sliding block 6 slides downwards to drive the outline gauge 2 to move, so that the bottom of the support 201 is in contact with the highest point of the special-shaped spring, and then the maximum outer diameter H0 of the special-shaped spring is obtained by observing the number indicating position of the bottom end of the support 201 in contact with the vertical steel plate ruler. At the moment, the contour gauge 2 presents the outer circle contour and the horizontal wave peak point of the special-shaped spring, different pitch sizes C1, C2, C3 and C4 of the special-shaped spring are measured through the horizontal distance of the horizontal wave peak point, and different outer diameter size differences H1, H2, H3 and H4 of the special-shaped spring are measured through the vertical distance of the horizontal wave peak point.

And finally, subtracting H0 from different outer diameter size differences H1, H2, H3 and H4 to obtain the sizes of the different outer diameters of the special-shaped spring.

The invention firstly measures the maximum outer diameter, then measures the size difference between the maximum outer diameter and other outer diameters through the contour gauge 2, and finally performs subtraction operation on the size difference between the maximum outer diameter and other outer diameters to obtain the size of the corresponding outer diameter. Because the special-shaped springs are various, in the actual measurement process, some special-shaped springs cannot obtain prepared data through one-time measurement, after one-time measurement, the maximum outer diameter size after the spring is rotated is kept unchanged through the rotating spring, the difference between the measured maximum outer diameter and the rest outer diameter size is measured, the corresponding outer diameter size is measured through subtraction operation, and finally, the data measured for multiple times are summarized to obtain the accurate outer diameter sizes of the special-shaped springs.
