Description

Technical Field

[0001] The utility model relates to a dust cover installation tool which is convenient for positioning and belongs to the technical field of transfer case assemblies. Background Art

[0002] Installing the dust cover is one of the important links in the production and manufacturing of the transfer case assembly. At present, due to the special structure of some transfer case assemblies, the dust cover needs to be installed on the input shaft. Due to the structure of the input shaft, it is difficult to position the dust cover when installing it, which causes the dust cover to be skewed or even damaged after installation. A skewed or damaged dust cover will reduce the dustproof performance of the dust cover for the transfer case assembly. At the same time, the skewed dust cover will scratch the transfer case housing and cause abnormal noise. At this time, the dust cover needs to be replaced, which will consume a lot of manpower and material resources. Utility Model Content

[0003] The utility model aims to provide a dust cover installation tool that is easy to position, so as to realize the positioning of the dust cover during the installation process and prevent the dust cover from being skewed or damaged after installation. The operation is simple and convenient, the production efficiency is improved, the production cost is saved, and the problems existing in the background technology are solved.

[0004] The technical solution of the utility model is:

[0005] A dust cover installation tool that is easy to position includes a positioning sleeve, a guide column, a handle, a rotating column, a rotating handle and a pressure head. The positioning sleeve is arranged inside the lower end of an input shaft, the guide column is arranged inside the input shaft, and the lower end is arranged in the positioning sleeve and fixed by the handle; a dust cover is installed on the top of the input shaft, and the upper end of the guide column extends out of the dust cover and is provided with a pressure head; rotating columns are symmetrically arranged on the positioning sleeves on both sides of the guide column, and the positioning sleeves are extended from both ends of the rotating column. A limit block is provided at one end of the rotating column in the input shaft, and a rotating handle is provided at the other end. The limit block is driven to rotate by rotating the rotating handle, thereby fixing the guide column and the input shaft.

[0006] The other end of the rotating column passes through the rotating handle and is fixed by a hexagonal nut. A spring washer is arranged on the rotating column between the rotating handle and the hexagonal nut.

[0007] The limit block and the rotating column are an integrated structure.

[0008] The input shaft is provided with a diameter-changing hole, and the limit block is clamped at the diameter-changing position of the diameter-changing hole.

[0009] The variable diameter hole is composed of a large hole and a small hole connected to each other. The large hole is arranged above the small hole. The aperture of the large hole is larger than the aperture of the small hole. The aperture of the small hole matches the outer diameter of the positioning sleeve. The limit block is clamped at the bottom of the large hole.

[0010] During installation, first insert the guide column into the positioning sleeve and fix it with a handle; pass the rotating column through the positioning sleeve, rotating handle and spring washer in sequence, and tighten and fix it with a hexagonal nut; insert the guide column and the positioning sleeve into the reducing hole of the input shaft together, and use the pressure head to position and install the dust cover through the guide column.

[0011] The beneficial effects of the utility model are: positioning the dust cover during the installation process, preventing the dust cover from being skewed or damaged after installation due to lack of positioning, simple and convenient operation, improved production efficiency, and saved production costs.

[0018] The present invention will be further described below through examples in conjunction with the accompanying drawings.

[0019] A dust cover installation tool that is easy to position includes a positioning sleeve 1, a guide column 2, a handle 3, a rotating column 4, a rotating handle 5 and a pressure head 8. The positioning sleeve 1 is arranged inside the lower end of an input shaft 10, and the guide column 2 is arranged inside the input shaft 10, and the lower end is arranged in the positioning sleeve 1 and fixed by the handle 3; a dust cover 9 is installed on the top of the input shaft 10, and the upper end of the guide column 2 extends out of the dust cover and is provided with a pressure head 8; rotating columns 4 are symmetrically arranged on the positioning sleeves 1 on both sides of the guide column 2, and both ends of the rotating column 4 extend out of the positioning sleeves 1, one end of the rotating column 4 is provided with a limit block 12 in the input shaft, and the other end is provided with a rotating handle 5, and the limit block 12 is driven to rotate by rotating the rotating handle 5, thereby fixing the guide column 2 and the input shaft 10.

[0020] The other end of the rotating column 4 passes through the rotating handle 5 and is fixed by a hexagonal nut 7 . A spring washer 6 is provided on the rotating column 4 between the rotating handle 5 and the hexagonal nut 7 .

[0021] The limit block 12 and the rotating column 4 are an integral structure.

[0022] The input shaft 10 is provided with a diameter-changing hole 11 , and a limit block 12 is clamped at the diameter-changing portion of the diameter-changing hole 11 .

[0023] The variable diameter hole 11 is composed of a large hole and a small hole connected to each other. The large hole is arranged above the small hole. The aperture of the large hole is larger than the aperture of the small hole. The aperture of the small hole matches the outer diameter of the positioning sleeve 1. The limit block 12 is clamped at the bottom of the large hole.

[0024] When using the utility model, the two rotating handles 5 are first rotated to retract the limit blocks 12 on the two rotating columns 4, the guide column 2 is inserted into the input shaft 10 and positioned by the positioning sleeve 1, and then the two rotating handles 5 are rotated to expand the limit blocks 12 on the two rotating columns 4, so that the utility model is fixed to the input shaft 10 as a whole, and finally the pressure head 8 is used to position the dust cover 9 through the guide column.
