[0001] The invention relates to the field of flange drilling, in particular to a drilling device for producing a spline flange of a washing machine clutch. Background Art

[0002] In the production process of washing machine clutch spline flange, drilling is one of the key processes. Traditional drilling methods have many disadvantages, which seriously affect production efficiency and product quality.

[0003] On the one hand, traditional drilling devices usually use a method of multiple positioning and step-by-step drilling, which not only increases the complexity of the operation process, but also significantly prolongs the drilling time and leads to low overall drilling efficiency, making it difficult to meet the needs of large-scale production.

[0004] On the other hand, during the drilling process, the high-speed friction between the drill bit and the flange material will generate a lot of heat. Due to the lack of effective cooling measures, the drill bit will be in a high temperature state for a long time, resulting in increased wear and reduced hardness, thereby shortening the service life of the drill bit and increasing production costs. At the same time, high temperature may also affect the performance of the flange material and the drilling accuracy, resulting in an increase in the defective rate. Summary of the Invention

[0018] 3. During drilling, the liquid pump is activated to deliver the cooling liquid from the liquid storage box to the annular cavity.

This reduces wear on the drill bit caused by high temperatures, extends the actual service life of the drill bit, reduces the frequency of drill bit replacement, and reduces production costs.

[0019] 4. After the cooling liquid, carrying debris, flows into the liquid storage box, the rotating rod drives the separation net to rotate, using centrifugal force to separate the debris from the cooling liquid. This design effectively recycles the cooling liquid, reduces cooling liquid waste, improves cooling liquid utilization, and reduces resource consumption.

[0020] 5. The stirring blades on the rotating rod rotate to promote the movement of the cooling liquid in the liquid storage box, making the overall temperature of the cooling liquid uniform, which facilitates the heat exchanger to effectively cool the cooling liquid. This ensures that the cooling liquid continues to have a good cooling effect, ensuring that the entire drilling device can operate continuously and stably, improving production continuity.

[0032] As an embodiment of the present invention, a circular opening 10 is opened in the middle of the support plate 1, and the circular opening 10 is connected to the liquid storage box 11. A mounting plate 15 is fixedly connected to the notch of the circular opening 10, and a limit assembly 16 is provided at the upper end of the mounting plate 15. The limit assembly 16 is a prior art and is used to limit the flange.

[0033] As an embodiment of the present invention, the liquid storage box 11 is filled with cooling liquid, and a heat exchanger 24 is installed at the lower end of the liquid storage box 11, and the heat exchange portion of the heat exchanger 24 extends into the interior of the liquid storage box 11;

[0034] As an embodiment of the present invention, it also includes a liquid recovery mechanism, which cooperates with the cooling mechanism. The liquid recovery mechanism includes a rotating rod 23 rotatably connected to the bottom of the liquid storage box 11. The upper end of the rotating rod 23 is fixedly connected to the separation net cylinder 22. The rotation of the separation net cylinder 22 can utilize centrifugal force to separate the debris and the cooling liquid more quickly, thereby improving the separation effect and thereby improving the utilization rate of the cooling liquid for vision.

[0035] As an embodiment of the present invention, the lower end of the horizontal part of the L-shaped plate 3 is rotatably connected to the rotating shaft 30, and the third bevel gear 28 is fixedly connected to the rotating shaft 30. The lower end of the rotating shaft 30 is stuck with a rectangular groove 14, and the upper end output shaft of the dual-axis motor 6 is fixedly connected to the rectangular bar 17. The upper end of the rectangular bar 17 extends to the inside of the rectangular groove 14 and is slidably connected to the inner wall of the rectangular groove 14. The rear side of the vertical part of the L-shaped plate 3 is rotatably connected to the first rotating shaft 20, and the front end of the first rotating shaft 20 is fixedly connected to the fourth bevel gear 29.

It is connected to a second rotating shaft 21, the rear end of the second rotating shaft 21 passes through the rear side wall of the liquid storage box 11, and the rear end of the first rotating shaft 20 passes through the rear side of the vertical portion of the L-shaped plate 3. The rear ends of the first rotating shaft 20 and the second rotating shaft 21 are both equipped with pulleys 18, and the two pulleys 18 are connected by a transmission belt 19. The front end of the second rotating shaft 21 is fixedly connected to a second bevel gear 27, and a first bevel gear 26 is installed on the rotating rod 23. The first bevel gear 26 is meshed with the second bevel gear 27, and a plurality of stirring blades 25 are installed on the rotating rod 23. The stirring blades 25 can promote the movement of the cooling liquid, so that its overall temperature is evenly cooled by the heat exchanger 24.

[0036] In the present invention, the clutch spline flange of the washing machine to be drilled is fixed by the limiting assembly 16 on the upper end of the mounting plate 15 to ensure that the flange is stable in position during the subsequent drilling process.

[0037] The dual-axis motor 6 installed at the upper end of the U-shaped plate 5 is started. The output shaft at the lower end of the dual-axis motor 6 passes through the U-shaped plate 5 and drives the main gear 9 to rotate. Since the main gear 9 is meshed with multiple driven gears 8, the rotation of the main gear 9 will drive the multiple driven gears 8 to rotate synchronously. The multiple driven gears 8 are respectively fixed to the upper ends of multiple drive shafts. The lower ends of the drive shafts pass through the lifting plate 7 and are fixedly connected to the upper end of the drill bit 32. Therefore, the rotation of the driven gears 8 will drive the drive shafts and the drill bit 32 to rotate. At the same time, the output shaft at the upper end of the dual-axis motor 6 drives the rectangular bar 17 to rotate. The rectangular bar 17 slides in the rectangular groove 14 and drives the rotating shaft 30 to rotate. The third bevel gear 28 on the rotating shaft 30 rotates accordingly. The third bevel gear 28 meshes with the fourth bevel gear 29 at the front end of the first rotating shaft 20, thereby driving the first rotating shaft 20 to rotate. Pulleys 18 are installed at the rear ends of the first rotating shaft 20 and the second rotating shaft 21. The two pulleys 18 are connected by a transmission belt 19. The rotation of the first rotating shaft 20 will drive the second rotating shaft 21 to rotate.

[0038] While the drill bit 32 rotates, the two hydraulic telescopic rods 4 symmetrically fixed at the lower end of the horizontal portion of the L-shaped plate 3 are controlled to extend. The telescopic ends of the two hydraulic telescopic rods 4 jointly drive the U-shaped plate 5 to descend, and the U-shaped plate 5 drives the lifting plate 7 to descend, thereby causing the multiple rotating drill bits 32 to move downward, performing a one-time drilling operation on the flange;

[0039] During the drilling process, the liquid pump 12 installed on the upper end of the support plate 1 is started. The liquid inlet end of the liquid pump 12 draws cooling liquid from the liquid storage box 11. The cooling liquid enters the hose 13 through the liquid outlet end of the liquid pump 12, then flows into the annular cavity 31 inside the lifting plate 7, and finally is sprayed out through multiple liquid spraying ports 33 opened at the bottom of the annular cavity 31. The multiple liquid spraying ports 33 are all directed towards the drilling location, thereby achieving cooling of the drill bit 32 and the drilling location;

[0040] The ejected cooling liquid carries the debris generated by the drilling and flows into the liquid storage box 11 through the circular opening 10. The front end of the second rotating shaft 21 is fixedly connected to the second bevel gear 27. The rotating rod 23 is mounted with a first bevel gear 26 that meshes with the second bevel gear 27. When the second rotating shaft 21 rotates, the meshing of the second bevel gear 27 and the first bevel gear 26 drives the rotating rod 23 to rotate. The rotation of the rotating rod 23 drives the separation net cylinder 22 to rotate, and the debris is separated from the cooling liquid by centrifugal force, thereby improving the utilization rate of the cooling liquid.

[0041] In addition, a plurality of stirring blades 25 are installed on the rotating rod 23. The rotation of the stirring blades 25 promotes the movement of the cooling liquid, making the overall temperature of the cooling liquid uniform, and facilitating the heat exchanger 24 installed at the lower end of the liquid storage box 11 to effectively cool the cooling liquid, ensuring that the cooling liquid continues to have a good cooling effect and ensuring continuous use of the whole.
