[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A dividing tool for processing a reducer housing includes a workbench main body 1, a connecting shell 2 is provided on the top of the workbench main body 1, a supporting platform 3 is rotatably connected inside the connecting shell 2, and further includes:

[0025] The rotating assembly 4 is located at the bottom of the connecting shell 2 and inside the workbench body 1, and the rotating assembly 4 is used to drive the connecting shell 2 and the supporting platform 3 to rotate;

[0026] The two sets of limit assemblies 5 are both located on the top of the support platform 3, and the limit assemblies 5 are used to limit and clamp the reducer housing.

[0027] Furthermore, the rotating assembly 4 is composed of a first worm gear 6, a first worm 7, a first driving rod 8, a second worm gear 9, a second worm 10 and a second driving rod 11. The first worm gear 6 is fixedly connected to the bottom of the connecting shell 2 and is located inside the workbench body 1. The first worm gear 7 is meshingly connected to the outer side of the first worm gear 6. The first driving rod 8 is fixedly connected to the end of the first worm gear 7 away from the first worm gear 6. The second worm gear 9 is fixedly connected to the outer side of the connecting shell 2. The second worm gear 10 is meshingly connected to the outer side of the second worm gear 9. The second driving rod 11 is fixedly connected to the end of the second worm gear 10 away from the second worm gear 9. When the reducer housing is processed, the reducer housing can be driven to rotate by the rotating assembly 4, thereby facilitating the processing of the reducer housing.

[0028] Among them, the first driving rod 8 is rotatably connected to the connecting shell 2, the second worm 10 and the second worm wheel 9 are both located inside the workbench body 1, the second driving rod 11 is rotatably connected to the workbench body 1, the support platform 3 passes through the connecting shell 2 and is fixedly connected to the first worm wheel 6. When processing the reducer housing, the reducer housing is placed on the top of the support platform 3, and the first driving rod 8 is rotated to drive the first worm 7 to rotate, so that the first worm wheel 6 can rotate, and drive the support platform 3 to rotate horizontally, so that the reducer housing placed on the top of the support platform 3 can rotate horizontally, and the second driving rod 11 is rotated to drive the second worm 10 to rotate, so that the second worm wheel 9 rotates, so that the connecting shell 2 can rotate longitudinally, and drive the support platform 3 and the reducer housing placed on the top thereof to rotate longitudinally.

[0029] Secondly, a receiving groove 12 is opened inside the workbench main body 1 and below the connecting shell 2. The internal structure size of the receiving groove 12 is designed to correspond to the external structure size of the connecting shell 2. The workbench main body 1 is connected to the connecting shell 2 through the receiving groove 12, and the connecting shell 2 is connected to the receiving groove 12, so that the connecting shell 2 can be connected to the workbench main body 1.

[0030] Furthermore, the limit assembly 5 is composed of a connecting block 13, a limit block 14, a rotating block 15, a rotating rod 16, a fixed block 17 and a fitting block 18. The connecting block 13 is located at the top of the support platform 3. The two groups of limit blocks 14 are slidably connected to the outside of the connecting block 13. The rotating block 15 is rotatably connected to the top of the connecting block 13. The two groups of rotating rods 16 are respectively rotatably connected to the two sides of the rotating block 15. The two groups of fixed blocks 17 are rotatably connected to the outside of the limit block 14. The two groups of fitting blocks 18 are rotatably connected to the outside of the fixed block 17.

When the limit block 14 contacts with the reducer housing, the fixed block 17 and the bonding block 18 are subjected to relative force to rotate and fit the surface of the reducer housing, so that it can be limited and clamped.

[0032] Furthermore, the surface of the bonding block 18 is provided with a plurality of groups of anti-slip strips, which are rubber anti-slip strips, and the plurality of groups of anti-slip strips are evenly spaced on the surface of the bonding block 18. When the bonding block 18 contacts the reducer housing, the anti-slip strips can increase the friction between the bonding block 18 and the reducer housing, thereby preventing the friction between the reducer housing and the bonding block 18 from being too small, thereby affecting the limiting position of the bonding block 18 on the reducer housing.

When the reducer housing is being processed, the reducer housing is placed on the top of the support platform 3 so that the reducer housing can contact with multiple groups of limit blocks 14, and the driving motor is started to drive the rotating block 15 to rotate, so that the rotating rod 16 can rotate, and drive the limit block 14 to move, so that the limit block 14 can contact with the reducer housing. When the limit block 14 contacts with the reducer housing, the fixed block 17 and the fitting block 18 are rotated by relative force and fit the surface of the reducer housing, so that it can be limited and clamped. Compared with the existing reducer housing tooling, the utility model can improve the overall practicality of the reducer housing tooling through design.
