Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1-4 The present invention provides the following technical solution:

[0035] A press-fit structure for a miniature bearing includes:

[0036] Workbench 1;

[0037] The first connecting block 2 is fixedly connected to the upper end of the workbench 1;

[0038] The second connecting block 3 is fixedly connected to the upper end of the first connecting block 2;

[0039] Hydraulic rod 4 is fixedly connected to the lower end of the second connecting block 3;

[0040] Pressing block 5 is fixedly connected to the lower end of hydraulic rod 4;

[0041] Mounting block 6 is fixedly connected to the upper end of workbench 1;

[0042] A semi-annular groove 7 is formed on one side of the mounting block 6.

[0043] Positioning hole 8 is provided on mounting block 6 and extends through the upper and lower ends of mounting block 6;

[0044] Positioning groove 9 is located at the lower end of pressing block 5;

[0045] Extension slot 10 is provided at the upper end of worktable 1;

[0046] Fixed block 11 is fixedly connected to the upper end of workbench 1.

[0047] In a specific embodiment of this utility model, the workbench 1, as the foundation of the entire pressing device, provides a stable support platform for all other components. The first connecting block 2 and the second connecting block 3 are stacked and fixed on the workbench 1 in sequence, forming a stable vertical support for supporting the hydraulic rod 4 and the pressing block 5 on it, thus improving the stability of the pressing process. The hydraulic rod 4 is used to press the shaft and the miniature bearing together; the hydraulic rod 4 is prior art and will not be described in detail here. The pressing block 5 is used to press the shaft and the miniature bearing together using the force of the hydraulic rod 4. The mounting block 6, located on the workbench 1, provides a mounting platform for the semi-annular groove 7 and the positioning hole 8. The groove 7 is used to place the miniature bearing to be press-fitted. The positioning hole 8 and positioning groove 9 are used to prevent the shaft to be press-fitted and to prevent the shaft from shaking during press-fitting, thus improving the accuracy of the press-fitting process. The extension groove 10 prevents the shaft from hitting the worktable 1 after the shaft and miniature bearing are press-fitted, which would cause damage to the miniature bearing. The fixing block 11 is used to provide support for the miniature bearing placed in the semi-annular groove 7, making the press-fitting of the miniature bearing more uniform. Through the combined action of the semi-annular groove 7 and positioning hole 8 on the mounting block 6 and the positioning groove 9 at the lower end of the pressing block 5, it is ensured that the miniature bearing and shaft to be press-fitted can be accurately aligned. This multi-point positioning design reduces human error and improves the accuracy of press-fitting.

[0048] Please refer to the details. Figures 1-4 A placement slot 19 is provided on one side of the workbench 1.

[0049] In this embodiment: the placement groove 19 can be used to place the pressed-fit miniature bearing, or to place items used by workers.

[0050] Please refer to the details. Figures 1-4 A T-slot 12 is provided on one side of the workbench 1, and a T-block 13 is slidably connected in the T-slot 12. A baffle 14 is fixedly connected to one side of the T-block 13.

[0051] In this embodiment, there are two T-shaped grooves 12 and T-shaped blocks 13. The T-shaped blocks 13 slide in the T-shaped grooves 12 to open and close the baffle 14, making it convenient for people to take out items. The baffle 14 is used to prevent external dust from entering the placement groove 19 and to protect the items in the placement groove 19 from the influence of external factors.

[0052] Please refer to the details. Figures 1-4 An L-shaped limit block 15 is fixedly connected to one side of the workbench 1.

[0053] In this embodiment, two L-shaped limiting blocks 15 are provided, which can make the baffle 14 more stable when opening and closing, and prevent the baffle 14 from shaking when opening and closing.

[0054] Please refer to the details. Figures 1-4 A handle 16 is fixedly connected to one side of the baffle 14, and the edge of the handle 16 is designed with rounded corners.

[0055] In this embodiment, the handle 16 makes it easier for personnel to open and close the baffle 14, and the rounded corner design of the edge makes it easier for personnel to open and close the baffle 14, improving the comfort of the hand.

[0056] Please refer to the details. Figures 1-4 The lower end of the workbench 1 is fixedly connected to a support column 17, and the lower end of the support column 17 is fixedly connected to a gasket 18.

[0057] In this embodiment, multiple support columns 17 and gaskets 18 are provided. The support columns 17 help reduce vibration or displacement generated during the pressing process, thereby improving the accuracy and safety of operation and making the device more stable during operation. The gaskets 18 increase the friction with the ground and prevent the entire device from sliding during use.

[0058] The working principle and usage process of this utility model are as follows: Personnel place the miniature bearing to be press-fitted in the semi-annular groove 7 of the mounting block 6 and on the fixing block 11. Then, the shaft is placed into the positioning hole 8, with one end of the shaft placed into the positioning groove 9, and the other end aligned with the pressing point of the miniature bearing. The hydraulic rod 4 is activated, causing the pressing block 5 to press the miniature bearing and shaft together. The pressing block 5 and the fixing block 11 ensure uniform force distribution during the pressing process. When the shaft is pressed axially downwards, the other end of the shaft enters the extension groove 10 through the miniature bearing, preventing contact between the shaft and the worktable 1. The hydraulic rod 4 drives the pressing block 5 downwards, and the positioning groove 9 at the lower end of the pressing block 5 engages with the shaft, improving the accuracy and stability of the pressing process. This solves the problem in the prior art where personnel need to manually align the miniature bearing and shaft during the pressing process, resulting in low precision and potential bearing damage or insecure installation.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
