Description

Technical Field

[0001] This utility model relates to the field of drive shaft brackets, and specifically to a bracket dynamic balancing positioning fixture. Background Technology

[0002] Reference Appendix Figure 1 The existing dynamic balance support is directly positioned by two arc-shaped columns (2') and the support bearing (3') of the transmission shaft bracket (1'), and the support is firmly fixed by the cylinder (4') and the pad (5') above.

[0003] However, as Figure 2 As shown, the existing support can be installed even if the bracket is not placed correctly. However, due to the interference between the column and the positioning hole (6'), the drive shaft will be distorted during balancing, resulting in inaccurate balancing data. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dynamic balancing positioning fixture for a bracket, which solves the problem of distorted dynamic balancing data caused by the bracket being placed crookedly.

[0005] The purpose of this utility model is achieved through the following technical solution: This support dynamic balancing positioning fixture includes a support shell and a support mounting base. A bearing is installed inside the support shell, and at least one support positioning hole is opened at the bottom of the bearing. Rod positioning holes are opened on the ears on both sides of the support shell. The support mounting base is located below the support shell. At least one positioning rod is provided on the support mounting base at a position corresponding to the rod positioning hole. A positioning post is provided on the support mounting base at a position corresponding to the support positioning hole. The positioning post extends into the corresponding support positioning hole only when the positioning rod is inserted into the rod positioning hole, so that the support shell is horizontally installed into the support mounting base.

[0006] As a further technical solution, a positioning cylinder is provided on the top of the bracket housing. The piston rod of the positioning cylinder is connected to drive the positioning pad, so that the positioning pad is pressed tightly on the top of the bracket housing.

[0007] As a further technical solution, the rod positioning hole matches the shape of the positioning rod, and both are waist-shaped.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. Add a positioning rod to the bracket mounting base to ensure that the bracket is in a horizontal position during installation, and to ensure that the dynamic balance positioning column can be fully aligned and snapped into the positioning hole of the bracket without interference;

[0010] 2. The bracket is pressed and positioned by the cylinder and pad, resulting in greater reliability;

[0011] 3. The waist-shaped rod positioning hole matches the positioning rod to prevent the bracket from tilting. Attached Figure Description

[0017] Explanation of reference numerals in the attached drawings: 1' drive shaft bracket, 2' column, 3' bracket bearing, 4' cylinder, 5' pad, 6' positioning hole; 1' bracket housing, 2' rod positioning hole, 3' bracket mounting base, 4' positioning rod, 5' bearing, 6' positioning pad, 7' positioning cylinder, 8' bracket positioning hole, 9' positioning column, 10' ear. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example: As attached Figures 3-5 As shown, this dynamic balancing positioning fixture for the bracket includes a bracket housing 1, a rod positioning hole 2, a bracket mounting base 3, a positioning rod 4, a bearing 5, a positioning pad 6, a positioning cylinder 7, a bracket positioning hole 8, a positioning column 9, and an ear 10.

[0020] Reference Appendix Figure 3 A bearing 5 is installed inside the bracket housing 1 (the outer periphery of the bearing 5 is fixed to the bracket housing 1 by a rubber body). Two bracket positioning holes 8 are symmetrically opened at the bottom of the bearing 5 (rubber body). At the same time, rod positioning holes 2 are symmetrically opened on the ears 10 on both sides of the bracket housing 1.

[0021] Furthermore, the bracket mounting base 3 is positioned below the bracket housing 1, and a positioning rod 4 is installed on the left side of the bracket mounting base 3 at a position corresponding to the rod positioning hole 2. Preferably, the shapes of the rod positioning hole 2 and the positioning rod 4 match, and both are oblong (e.g., ...). Figure 4 , 5(As shown). Furthermore, a positioning post 9 is provided on the bracket mounting base 3 at a position corresponding to each bracket positioning hole 8. The positioning post 9 extends precisely into the corresponding bracket positioning hole 8 only when the positioning rod 4 is inserted into the rod positioning hole 2, ensuring the bracket housing 1 is installed horizontally into the bracket mounting base 3. If the bracket housing 1 is tilted, the positioning rod 4 will not align with the rod positioning hole 2, and the positioning post 9 will also not align with the bracket positioning hole 8, preventing proper installation.

[0022] Preferably, a positioning cylinder 7 is provided on the top of the bracket housing 1. The piston rod of the positioning cylinder 7 is connected to drive the positioning pad 6, so that the positioning pad 6 is pressed against the top of the bracket housing 1.

[0023] The working process of this utility model:

[0024] This invention incorporates a waist-shaped positioning rod 4 on the left side of the original bracket mounting base 3. During bracket installation, the two positioning pins 9 can only smoothly enter the bracket positioning holes 8 when the bracket housing 1 remains horizontal, i.e., when the waist-shaped hole (rod positioning hole 2) on the left side of the bracket housing 1 is aligned with the positioning rod 4. If the bracket housing 1 is tilted, the positioning rod 4 cannot smoothly enter the rod positioning hole 2, and the positioning pins 9 cannot be aligned with the bracket positioning holes 8, thus preventing proper installation and achieving error prevention.

[0025] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
