[0002] Automobile steel plate spring, also called blade spring, commonly known as steel plate, steel plate spring is the most widely used elastic element in automobile suspension, which is a nearly equal strength elastic beam combined by a plurality of alloy spring sheets of equal width but unequal length (thickness can be equal or not equal).

[0003] The steel plate spring needs to be measured during production to meet the factory standard. The measurement of the steel plate spring focuses on the balance degree and perpendicularity measurement of the eye of the steel plate spring. However, in the actual process, there is no special measuring tool, which requires multiple people to cooperate during measurement, not only the measurement efficiency is low, but also the steel plate spring is in the shape of an arc, the center of gravity is not stable during measurement, and shaking easily occurs, which leads to large deviation of the measurement accuracy and affects the production process of the steel plate spring. SUMMARY

[0004] The utility model discloses a balance degree and perpendicularity measurement subassembly for steel plate spring production, and overcomes the above-mentioned prior art deficiencies, which effectively solves the existing problems of low steel plate spring measurement efficiency and large deviation.

[0006] Further, the support tool includes a pair of I-shaped frames, a cross bar is connected between the pair of I-shaped frames, and a first concave clamping seat is installed on the cross beam of the I-shaped frame.

[0007] Further, a second concave clamping seat is installed on the cross beam of the I-shaped frame.

[0008] Further, the rectangular tube is made of aluminum material.

[0009] Further, the screw is a hexagonal socket head cap screw.

[0010] The utility model discloses an advantageous effect: through measuring tool can be to the steel plate spring two ear -ring fast balance degree and perpendicularity measurement, thereby improved measurement efficiency and measurement accuracy, second, through the support tool can place the steel plate spring steadily, further convenient for measuring tool accurate to its measurement, and after measurement can place measuring tool steadily on support tool again, prevent measuring tool from being damaged by external force.

[0017] In the drawing, 1 rectangular pipe, 2 sliding sleeve, 3 screw, 4 concave positioning seat, 5 through -hole, 6 I -beam, 7 cross bar, 8 first concave clamping seat, 9 second concave clamping seat, 10 steel plate spring, 11 pin shaft. DETAILED DESCRIPTION

[0018] In order to have more clear understanding to the technical features, object and effect of the utility model, now the specific implementation mode of the utility model is explained with the drawings:

[0019] As Figs. 1 to 3 Shown, the balance degree and perpendicularity measurement assembly for steel plate spring production, including measuring tool and support tool, the measuring tool includes rectangular pipe 1, in both ends of rectangular pipe 1 are matched with the sleeve of sliding sleeve 2, in the top wall center of sliding sleeve 2, set up the screw hole, in the screw hole, screw with screw 3, in the bottom wall of sliding sleeve 2, install concave positioning seat 4, in the both side walls of concave positioning seat 4, set up through -hole 5, in the through -hole 5, matched installation has pin shaft sleeve;The support tool is used for placing steel plate spring 10 and measuring tool steadily.

[0020] Specifically, through measuring tool can be to the steel plate spring 10 two ear -ring fast balance degree and perpendicularity measurement.

[0021] In actual use, the staff first obtains the center distance dimension between the two ends of the plate spring 10 from the production drawing, and then marks the two end points (marking points) corresponding to the dimension on the top wall of the rectangular tube 1. At this time, the sliding sleeve 2 is slid on the rectangular tube 1 to the marking points, and the screw hole center is aligned with the marking points. At this time, the screw 3 is screwed into the screw hole, so that the position of the sliding sleeve 2 on the rectangular tube 1 is fixed. At this time, the center distance dimension between the screw holes on the two sliding sleeves 2 is the same as the center distance dimension between the two ends of the plate spring 10. At this time, the rectangular tube 1 is lifted, the concave positioning seat 4 is buckled on the grommet of the plate spring 10, and the pin shaft corresponding to the type of the grommet of the plate spring 10 is inserted into the through hole 5. If the grommets at both ends of the plate spring 10 are balanced and vertical, the pin shaft can be inserted into the grommet. The plate spring 10 meets the design standard. If the grommets at both ends of the plate spring 10 are not balanced and vertical, the pin shaft cannot be inserted into the grommet. The plate spring 10 does not meet the design standard.

[0022] As shown in Figs. 4 to 6 The support tool includes a pair of I-shaped frames 6, a cross bar 7 is connected between the pair of I-shaped frames 6, a first concave clamping seat 8 is installed on the cross beam of the I-shaped frame 6, the plate spring 10 is placed in the groove of the first concave clamping seat 8, a second concave clamping seat 9 is installed on the cross beam of the I-shaped frame 6, and the rectangular tube 1 is placed in the groove of the second concave clamping seat 9. The rectangular tube 1 is made of aluminum, and the screw 3 is an internal hexagonal screw.

[0023] Specifically, the plate spring 10 can be stably placed by the support tool, so that the measurement tool can accurately measure it. After the measurement is completed, the measurement tool can be stably placed on the support tool again, so as to prevent the measurement tool from being damaged by external force.

[0024] In actual use, the two ends of the plate spring 10 are placed in the first concave clamping seat 8 correspondingly, and the swinging of the plate spring 10 is prevented under the limiting of the first concave clamping seat 8. After the measurement is completed, the two ends of the measurement tool rectangular tube 1 are placed in the second concave clamping seat 9 correspondingly, so as to avoid that the measurement tool is directly placed on the working ground and is damaged by external force.

[0025] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
