Technical Field

[0001] This utility model relates to the field of leaf spring testing, specifically to a tool for testing the symmetry of the center hole of a leaf spring steel plate. Background Technology

[0002] The leaf spring can be found in patent application number CN201811461613.X. It is made of multiple steel plates spliced ​​together, with a central hole in each plate. The symmetry of the central hole is an important parameter of the steel plate. If the error of the central hole is too large, it will seriously affect the quality of the leaf spring.

[0003] When inspecting the symmetry of the center hole in a steel plate, workers need to measure the distance from the center hole to both ends of the steel plate to determine the symmetry. However, the above method for detecting the centerness of the steel plate requires frequent measurement of the distance from the center hole to both ends of the steel plate, which is cumbersome and inefficient.

[0004] Therefore, improving the detection efficiency of the symmetry of the center hole of the leaf spring steel plate is an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a tool for detecting the symmetry of the center hole of a leaf spring steel plate, thereby solving the technical problem that the detection of the symmetry of the center hole of a leaf spring steel plate is cumbersome and laborious in the prior art.

[0009] In some embodiments, the locking pin passes through the support rod, and one end of the locking pin has a large-diameter locking head, while the other end of the locking pin has a small-diameter locking head.

[0010] In some embodiments, the support rod has a plurality of first mounting holes, and a plurality of the locking pins are inserted through the first mounting holes in a corresponding manner.

[0011] In some embodiments, the support rod has a plurality of first screw holes, and the plurality of first screw holes are connected one-to-one with the plurality of first mounting holes. The support rod also has a plurality of first bolts, which are screwed into the first screw holes and press against the locking post to prevent the locking post from disengaging from the first mounting hole.

[0012] In some embodiments, the leaf spring steel plate center hole symmetry detection tool further includes a base sleeve and several clamping sleeves. The base sleeve is detachably fitted onto the base post, and the several clamping sleeves are fitted onto the several clamping posts in a corresponding manner.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the tedious and laborious technical problem of detecting the symmetry of the center hole in a leaf spring, this invention provides a tool for detecting the symmetry of the center hole in a leaf spring. This tool can quickly verify the symmetry of the center hole in a leaf spring without requiring specific measurements.

[0021] It should be noted that the leaf spring steel plate center hole symmetry detection tool of this utility model is used for leaf spring steel plate center hole detection, etc. For ease of explanation, this utility model will only use the application of the leaf spring steel plate center hole symmetry detection tool to leaf spring steel plate center hole detection as an example for explanation.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a leaf spring steel plate center hole symmetry detection tool in one embodiment of the present invention. The leaf spring steel plate center hole symmetry detection tool includes a support rod 100, a base column 200 and two locking pieces 300. The base column 200 is installed on the support rod 100, and the two locking pieces 300 are symmetrically installed on the support rod 100 with the base column 200 as the center.

[0023] First, insert the base post 200 into the center hole of the leaf spring plate, aligning the two locking pieces 300 with both ends of the leaf spring plate. If both locking pieces 300 are aligned with both ends of the leaf spring plate, the distance from the center hole to the end of the leaf spring plate is equal, indicating that the symmetry of the center hole meets the requirements. If either locking piece 300 cannot be aligned with the end of the leaf spring plate, the distance from the center hole to the end of the leaf spring plate is unequal, indicating that the symmetry of the center hole does not meet the requirements. Compared to measuring the distance at the end of the center hole with calipers, the above-mentioned leaf spring plate center hole symmetry testing tool does not require measuring specific values ​​and can quickly verify the symmetry of the leaf spring plate center hole.

[0024] In some embodiments, each of the two locking members 300 includes a plurality of locking posts 310, which are symmetrically installed on the support rod 100 with the base post 200 as the center, corresponding one-to-one with each other. Each pair of corresponding locking posts 310 corresponds to a leaf spring steel plate of a certain specification. The longer the leaf spring steel plate, the larger the distance between the two corresponding locking posts 310. The shorter the leaf spring steel plate, the smaller the distance between the two corresponding locking posts 310. Since this application has multiple pairs of locking posts 310 with different spacings, the leaf spring steel plate center hole symmetry detection tool can be applied to leaf spring steel plates of different specifications.

[0025] Based on the above embodiments, in some embodiments, the lengths of the plurality of locking posts 310 decrease sequentially along the direction approaching the base post 200. This results in the locking posts 310 with smaller spacing having shorter lengths than those with larger spacing. Therefore, when detecting larger-sized leaf spring steel plates, the base post 200 corresponding to the smaller-sized plates, due to its shorter length, will not obstruct the detection of the larger-sized leaf spring steel plates. Conversely, when detecting smaller-sized leaf spring steel plates, the base post 200 corresponding to the larger-sized plates obviously cannot contact the smaller-sized plates, and therefore will not obstruct the detection of the smaller-sized leaf spring steel plates.

[0026] In some embodiments, the locking post 310 penetrates the support rod 100, and one end of the locking post 310 has a larger diameter locking head, while the other end has a smaller diameter locking head. It is understood that, to ensure the accuracy of the inspection, the operator uses the clearer edge of the locking post 310 to compare with the end of the leaf spring steel plate. The diameter of the locking post 310 affects the spacing of its edges. Because the two ends of the locking post 310 have different diameters, the same pair of locking posts 310 can be used to inspect leaf spring steel plates of different specifications, further improving the applicability of the leaf spring steel plate center hole symmetry inspection tool.

[0027] Understandably, the end of the base column 200 needs to fit tightly against the center hole of the leaf spring steel plate, and the center holes of leaf spring steel plates of different specifications vary. In some embodiments, the base column 200 penetrates the support rod 100, with one end of the base column 200 having a larger diameter center end and the other end having a smaller diameter center end. Because the diameters at both ends of the base column 200 are different, a center hole of a different specification can be used at each end of the base column 200.

[0028] Based on the above embodiments, in some embodiments, the leaf spring steel plate center hole symmetry detection tool further includes a base sleeve 400 and several clamping sleeves 500. The base sleeve 400 is detachably fitted onto the base post 200, and the several clamping sleeves 500 are fitted one-to-one onto several clamping posts 310. Fitting the base sleeve 400 onto the base post 200 can be regarded as increasing the diameter of the base post 200, while fitting the clamping sleeves 500 onto the clamping posts 310 can be regarded as increasing the diameter of the clamping posts 310.

[0029] In some embodiments, the support rod 100 has a plurality of first mounting holes 110, and a plurality of locking posts 310 are inserted one-to-one through the first mounting holes 110. The inner wall of the first mounting hole 110 fits against the outer wall of the locking post 310, thereby effectively positioning the locking post 310.

[0030] Based on the above embodiments, in some embodiments, the support rod 100 has a plurality of first screw holes 120, and the plurality of first screw holes 120 are connected one-to-one with a plurality of first mounting holes 110. The support rod 100 also has a plurality of first bolts 150, the first bolts 150 being screwed into the first screw holes 120 and pressing against the retaining post 310 to prevent the retaining post 310 from disengaging from the first mounting hole 110. Because the first bolts 150 press against the retaining post 310, the friction between the first bolts 150 and the retaining post 310 prevents the retaining post 310 from disengaging from the first mounting hole 110.

[0031] In some embodiments, the support rod 100 also has a second mounting hole 130, through which the base column 200 passes. The inner wall of the second mounting hole 130 fits against the inner wall of the base column 200, thereby effectively positioning the base column 200.

[0032] In some embodiments, the support rod 100 also has a second threaded hole 140 communicating with the second mounting hole 130, and the support rod 100 also has a second bolt 160, which is screwed into the second threaded hole 140 and presses against the base column 200 to prevent the base column 200 from disengaging from the second mounting hole 130. Because the second bolt 160 presses against the base column 200, the friction between the second bolt 160 and the base column 200 prevents the base column 200 from disengaging from the second mounting hole 130.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: First, the first bolt 150 presses against the retaining post 310, using the friction between the first bolt 150 and the retaining post 310 to prevent the retaining post 310 from disengaging from the first mounting hole 110. Then, the second bolt 160 presses against the base post 200, using the friction between the second bolt 160 and the base post 200 to prevent the base post 200 from disengaging from the second mounting hole 130. Next, the base post 200 is inserted into the center hole of the leaf spring plate, with the two retaining members 300 aligned with both ends of the leaf spring plate. If both retaining members 300 are aligned with both ends of the leaf spring plate, the distance from the center hole to the end of the leaf spring plate is equal, indicating that the symmetry of the center hole meets the requirements. If either retaining member 300 cannot be aligned with the end of the leaf spring plate, the distance from the center hole to the end of the leaf spring plate is unequal, indicating that the symmetry of the center hole does not meet the requirements. Compared to measuring the distance between the ends of the center hole with calipers, the above-mentioned leaf spring steel plate center hole symmetry detection tool does not require measuring specific values ​​and can quickly verify the symmetry of the leaf spring steel plate center hole.
