Description

Technical Field

[0001] The utility model relates to the technical field of positioning and installing a suspension support of a truck crane, in particular to a suspension support positioning tool. Background Art

[0002] like Figures 1 to 3 As shown, in a truck crane, the rear axle on the chassis frame is mounted on a suspension support 10a. This support 10a consists of two parts: a leaf spring support 11a for mounting a leaf spring and a thrust rod support 12a for mounting a V-shaped thrust rod. These two parts form a set of suspension supports 10a. Leaf spring support 11a is provided with leaf spring mounting holes 11b, while thrust rod support 12a is provided with thrust rod mounting holes 12b. When welding suspension supports 10a to frame box 13a, the longitudinal centerline 14a of suspension supports 10a must be aligned with the longitudinal centerline 14b of frame box 13a. There must be no angular deviation. Any angular deviation would cause the vehicle's rear axle to tilt after installation, leading to vehicle deviation.

[0003] Currently, in the prior art, a frame centerline 14b of the frame box 13a along the length direction is determined by a string, and a ruler is used to determine the distances of both sides of the suspension mount 10a in the width direction from the frame centerline 14b of the frame box 13a along the length direction, to determine whether the length centerline 14a of the suspension mount 10a coincides with the frame centerline 14b of the frame box 13a.

[0004] Therefore, the conventional method for determining whether the length centerline 14a of the suspension support 10a coincides with the frame centerline 14b of the frame box 13a has a large error, and it is impossible to intuitively see whether the two centerlines deviate. Utility Model Content

[0005] In view of this, the utility model provides a suspension support positioning tool, which can intuitively determine whether the length center line of the suspension support coincides with the frame center line of the frame box, avoiding the error of a ruler, and can be observed while spot welding, which is more reliable than a ruler, making it easier to determine whether the position of the suspension support is accurate.

[0006] A suspension support positioning tool includes a first positioning assembly and a second positioning assembly connected to each other, wherein the first positioning assembly is provided with a first positioning portion, the first positioning portion is used for positioning the suspension support in the length direction, and the second positioning assembly is provided with a second positioning portion, the second positioning portion is used for positioning the length center line of the suspension support and points to the plane where the bottom of the suspension support is located.

By observing whether the second positioning part points to the stretched frame center line or the drawn frame center line, it is possible to judge whether the length center line of the suspension support coincides with the frame center line of the frame box, thereby judging whether the position of the suspension support is accurate. Therefore, according to the suspension support positioning tool of the present invention, it is possible to intuitively judge whether the length center line of the suspension support coincides with the frame center line of the frame box, avoiding the error of a ruler, and can observe while spot welding, which is more reliable than a ruler, thereby facilitating the judgment of whether the position of the suspension support is accurate.

The first positioning part of the plate-like structure has a simple structure, is easy to install, and is stable and reliable.

[0014] In one embodiment, the first positioning components include two groups, a connecting portion is provided between the two groups of first positioning components, and a reinforcing rib structure is provided at the connection between the connecting portion and the first positioning components.

[0015] By setting up two groups of first positioning components to perform precise positioning from the two groups of mounting surfaces of the leaf spring support, the positioning accuracy and reliability of the entire suspension support positioning tooling can also be improved.

[0044] like Figures 4 to 6As shown, specifically, in this embodiment, the support positioning portion 11b is a leaf spring mounting hole, the first positioning component 11 is a plate-like structure, and the first positioning portion 111 is a positioning hole provided on the plate-like structure. The outer side surface of the first positioning component 11 is used to fit on the mounting surface 111a of the leaf spring support 11a, so that the center line of the positioning hole coincides with the center line of the leaf spring mounting hole. Specifically, the positioning hole on the first positioning component 11 coincides with the leaf spring mounting hole on the leaf spring support 11a, achieving precise positioning of the first positioning component 11 when connected to the mounting surface 111a of the leaf spring support 11a. The plate-like structure of the first positioning portion 111 is simple in structure, easy to install, and stable and reliable.

Reinforcing rib structures 15 are provided at the connection between the connecting portion 14 and the first positioning assembly 11. By providing two groups of first positioning assemblies 11 for precise positioning from the two groups of mounting surfaces 111a of the leaf spring support 11a, the positioning accuracy and reliability of the entire suspension support positioning tool can also be improved. The structure is simple and compact, easy to install, and stable and reliable.

[0046] like Figures 4 to 6 As shown, specifically, in this embodiment, the second positioning assemblies 12 respectively connected to the two groups of first positioning assemblies 11 are connected to each other, and the top of the second positioning assembly 12 is provided with a reinforcing beam 16 extending along the length direction of the suspension support 10a, and the reinforcing beam 16 is passed through the first positioning assembly 11. By further providing the reinforcing beam 16 of the above structure, the first positioning assembly 11 and the second positioning assembly 12 also have the advantages of simple and compact structure, easy installation, stability and reliability. Specifically, the reinforcing beam 16 is a hollow rectangular tube structure, which can effectively reduce the weight of the entire positioning tooling and is easy to process and manufacture. By further providing the reinforcing beam 16 of the above structure, the first positioning assembly 11 and the second positioning assembly 12 also have the advantages of simple and compact structure, easy installation, stability and reliability.

It also facilitates the arrangement of the positioning surface 122 and the second positioning portion 121 at the second end 124 of the second positioning assembly 12, and also facilitates the operator to determine whether the position of the suspension mount 10a is accurate.

[0048] like Figure 4 and Figure 5Specifically, in this embodiment, the second positioning portion 121 includes at least two sets of pointer structures. A mounting boss 125 is provided on the second positioning assembly 12.

Specifically, by further providing the third positioning assembly 13 to position the thrust rod support 12a, the accuracy and reliability of the position of the suspension support 10a can be further improved. Specifically, in this embodiment, the thrust rod support 12a is provided with a thrust rod mounting hole 121a. The third positioning portion 131 is a positioning connector used to connect to the thrust rod mounting hole 121a. It is easy to understand that the positioning connecting piece can be a fastener such as a pin.
