Description

Technical Field

[0001] The present application relates to the technical field of installation tooling, and specifically to a bushing installation tooling for a bulldozer. Background Art

[0002] The statements in this part merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] A bushing is a part used to reduce friction and wear between mechanical components. It is usually installed between a shaft and a hole to protect the shaft and the hole.

[0004] In the installation of the bogie bushing of a bulldozer, interference fit is generally adopted. The outer diameter of the bushing is larger than the inner diameter of the bogie installation hole, and the inner hole of the bushing is smaller than the outer diameter of the shaft. The load is transmitted by the frictional force generated by the interference. In this way, the bushing does not move relatively during operation. However, in the installation of the interference fit, since the outer diameter of the bushing is larger than the inner diameter of the bogie installation hole, it is not convenient for actual installation. During the process of forcibly inserting the bushing, the bushing is prone to indentation, resulting in damage to the integrity of the bushing. Therefore, a bushing installation tooling for a bulldozer is needed to solve the problems of inconvenient installation of the interference fit between the bushing and the bogie installation hole and easy damage to the bushing. Summary of the Utility Model

[0005] The present application proposes a bushing installation tooling for a bulldozer to solve the above problems.

[0006] The purpose of the present application is to provide a bushing installation tooling for a bulldozer. The inner ring of the bushing is supported by a cross support rod. By knocking the push rod, the cross support rod pushes the closed side of the bushing, driving the bushing to move towards the bogie installation hole. If the bushing is indented after installation, the push rod is rotated to drive the cross support rod to rotate, and the indented part is smoothed.

[0007] To achieve the above purpose, the present application adopts the following technical solutions:

[0008] A bushing installation tooling for a bulldozer includes: a cross support rod and a push rod. The length of the cross support rod is equal to the inner diameter of the bushing. The edge of the cross support rod is circular arc-shaped, which can better fit the inner ring of the bushing. The center of the cross support rod is connected to the push rod. The push rod is perpendicular to the cross support rod. A step is provided on the side of the cross support rod away from the push rod. The step is located at the edge of the cross support rod, which can facilitate the insertion of the cross support rod into the bushing.

[0009] As a further preference, the edge of the step is arc-shaped.

[0010] As a further preference, four reinforcing ribs are also provided at the connection between the push rod and the cross support rod, and the reinforcing ribs are fixed to the push rod and the cross rod support by welding.

[0011] As a further preference, the length of the push rod is greater than the length of the bushing.

[0012] As a further preference, the cross support rod includes a cross bar and a vertical rod. The lengths and widths of the cross bar and the vertical rod are the same, and the centers of the cross bar and the vertical rod intersect and are perpendicular to each other.

[0013] Compared with the prior art, the beneficial effects of the present application are as follows:

[0014] 1. In the present application, the inner ring of the bushing is supported by the cross support rod. When the bushing is inserted into the mounting hole of the trolley, there are four points for support, which maximally ensures that the bushing does not sink inwards. If the bushing sinks inwards after installation, the outer arc of the cross support rod can be closely attached to the inner ring of the bushing, and the cross support rod is rotated by rotating the push rod to smooth the sunken part.

[0015] 2. In the present application, by knocking on the push rod, the cross support rod pushes the closed side of the bushing, driving the bushing to move towards the direction of the trolley mounting hole. In this way, it is not necessary to manually press the bushing from the outside to prevent the bushing from deforming, but to support it from the inside of the bushing, and the installation effect is better.

[0020] The present application will be further described below in conjunction with the drawings and embodiments. Embodiment

[0021] A bushing installation tool for a bulldozer, as Figures 1-3As shown in the figure, it includes a cross-shaped support rod 1 and a push rod 2. The length of the cross-shaped support rod 1 is equal to the inner diameter of the bushing 6. The edge of the cross-shaped support rod 1 is arc-shaped, which can better fit the inner circle of the bushing 6. The center of the cross-shaped support rod 1 is connected to the push rod 2. The push rod 2 is perpendicular to the cross-shaped support rod 1. The cross-shaped support rod 1 and the push rod 2 are fixed by welding. A step 3 is provided on the side of the cross-shaped support rod 1 away from the push rod 2. The step 3 is located at the edge of the cross-shaped support rod 1, and the step 3 can facilitate the insertion of the cross-shaped support rod 1 into the bushing 6.

[0022] As Figure 3 shown in the figure, first insert the cross-shaped support rod 1 into the inner circle of the bushing 6 so that the cross-shaped support rod 1 is closely attached to the closed side of the bushing 6. Then apply lubricating oil on the outside of the bushing 6 to facilitate interference fit installation. Next, align the closed end of the bushing 6 with the trolley mounting hole 5 and insert the bushing 6 into the mounting hole. By knocking on the end of the push rod 2 away from the cross-shaped support rod 1, drive the bushing 6 to move towards the trolley mounting hole 5, and thus the installation can be completed. When rotating the push rod 2, the push rod 2 drives the cross-shaped support rod 1 to rotate, and in this way, the unevenness in the bushing 6 can be smoothed out by the cross-shaped support rod 1, improving the installation effect of the bushing 6.

[0023] As Figure 1 shown in the figure, the edge of the step 3 is arc-shaped, which is convenient for fitting with the inner circle of the bushing 6, and the step 3 effectively prevents the radial movement of the assembled bushing 6.

[0024] As Figure 2 shown in the figure, four reinforcing ribs 4 are also provided at the connection between the push rod 2 and the cross-shaped support rod 1. The reinforcing ribs 4 are fixed to the push rod 2 and the cross-shaped rod support by welding. The connection between the push rod 2 and the cross-shaped support rod 1 is strengthened by the reinforcing ribs 4, improving the strength and service life of the tooling.

[0025] The length of the push rod 2 is greater than the length of the bushing 6. During installation, it is convenient to knock on the push rod 2 without affecting the bushing 6.

[0026] The cross-shaped support rod 1 includes a horizontal rod and a vertical rod. The lengths and widths of the horizontal rod and the vertical rod are the same. The centers of the horizontal rod and the vertical rod intersect and are perpendicular to each other, which can ensure the support strength of the cross-shaped support rod 1.

[0027] As Figure 3As shown in the figure, during the installation process of the bushing 6 in this application, first, the bushing 6 is sleeved on the outside of the cross support rod 1. In this way, the support of the cross support rod 1 can be utilized to prevent the bushing 6 from deforming during the installation process, which may affect the subsequent installation of the bushing 6 and the shaft. Then, an appropriate amount of lubricating oil is applied to the outside of the bushing 6, and the bushing 6 is aligned with the trolley installation hole 5. Since one side of the bushing 6 is closed, the closed side of the cross support rod 1 and the bushing 6 are closely attached. Finally, the push rod 2 is struck, and the pressure exerted by the push rod 2 on the cross support rod 1 is utilized. In this way, the installation can be carried out from the inside of the bushing 6, pressing the bushing 6 into the trolley installation hole 5, solving the problem of damaging the bushing 6 during external installation. At the same time, the problem of interference fit, which makes it difficult to insert the bushing 6 into the trolley installation hole 5, can be solved.

[0028] Although the specific implementation manner of this application has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of this application. Those skilled in the art should understand that based on the technical solution of this application, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of this application.
