[0023] 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.

[0024] Example 1: Please refer to Figures 1-4 and Figure 6 The existing bearing housing inner hole manufacturing device needs to be installed on the chuck of a lathe, which is not convenient for precise positioning and installation. In order to solve this technical problem, this embodiment discloses the following technical content;

[0025] The top left and right sides of the chassis 1 are provided with arc-shaped grooves 2, and the inner side of the arc-shaped grooves 2 is connected to a counterweight 3. The lower left and right ends of the chassis 1 are provided with several mounting holes 4, and the mounting holes 4 are threaded with a first stabilizing bolt 5.

[0026] The counterweight 3 is fixedly connected to the chuck of the lathe. When installing the chassis 1, first align the arc groove 2 with the counterweight 3, and then use the first stabilizing bolt 5 to fix the chassis 1, so that the chassis 1 can be accurately fixed on the chuck.

[0027] Example 2: Existing devices for manufacturing bearing housing inner holes come in many different sizes and models of bearing housings, making it inconvenient to adjust and fix the dimensions. Therefore, this example uses the following technical solution, such as... Figures 1-6 As shown;

[0028] A through hole 6 is provided in the middle of the chassis 1, and a set of storage slots 7 are provided on the upper, lower, left and right sides of the front side of the chassis 1. A left clamping block 8 is connected to the left front side of the chassis 1, a top clamping block 9 is connected to the upper front side of the chassis 1, a right clamping block 10 is connected to the right front side of the chassis 1, and a bottom support plate 11 is connected to the bottom front side of the chassis 1. Anti-slip rods 12 are fixedly connected to the middle of the upper and lower rear sides of the left clamping block 8, and the anti-slip rods 12 are slidably connected in the corresponding storage slots 7. Anti-slip rods 12 are fixedly connected to both ends of the middle rear sides of the top clamping block 9, the right clamping block 10 and the bottom support plate 11. A connecting plate 13 is fixedly connected to the middle of the left side of the right end of the left clamping block 8. A connecting plate 13 is fixedly connected to the middle outer side of the top clamping block 9, the right clamping block 10 and the bottom support plate 11. A second stabilizing bolt 14 is threadedly connected to the middle of the connecting plate 13.

[0029] Place the bearing housing on the bottom support plate 11, align the inner hole with the through hole 6, and then adjust the position of the bearing housing. When the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11 move, the anti-slip rod 12 slides in the storage groove 7. After adjusting the position of the bearing housing, the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11 are used to fix the bearing housing. Move the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11 inward so that the inner side of the clamping blocks is in contact with the outer side of the bearing housing. The fixing size can be adjusted according to the bearing housing of different models and sizes.

[0030] Example 3: Existing bearing housing inner hole manufacturing devices are not convenient for continuous processing when machining bearing housings of the same model and size. Therefore, this example uses the following technical solution, such as... Figures 1-3 , Figure 5 and Figure 6 As shown;

[0031] Fixing holes 15 are provided at the upper and lower ends of the middle part of the left clamping block 8, and fixing holes 15 are provided in the middle of the top clamping block 9, the right clamping block 10 and the bottom support plate 11, and bolts are connected in the fixing holes 15.

[0032] After clamping the bearing housing, bolts are needed to pass through the fixing holes 15 to fix the bearing housing to the inner rear end of the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11. Then the bearing housing is processed. When processing bearing housings of the same model and size, it is not necessary to adjust the data between the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11. Just loosen the bolts in the fixing holes 15, remove the processed bearing housing, install the new bearing housing between the left clamping block 8, top clamping block 9, right clamping block 10 and bottom support plate 11, and then tighten the bolts in the fixing holes 15. Continuous processing is possible.

[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
