Description

Technical Field

[0001] The utility model relates to a gear hobbing machine, in particular to a gear hobbing machine for machining a motor shaft, and belongs to the technical field of motor shaft machining. Background Art

[0002] In the prior art, for example, the utility model with application number 202223033375.7 discloses a CNC gear hobbing machine. In order to solve the problem that debris is generated during the production process and the debris flies everywhere, causing the gear hobbing machine processing table to be too messy, if it is not cleaned for a long time, the debris accumulates on the gear hobbing machine, which easily affects the processing accuracy of the gear hobbing machine and causes the quality of the semi-finished products processed by the gear hobbing machine to be poor, a fan is used to suck the debris together with the air into the slag collecting box, and the debris generated when the gear hobbing machine body processes parts can be collected in the slag collecting box, reducing the accumulation of debris on the processing table, which is beneficial for the gear hobbing machine to process semi-finished products.

[0003] Similar to the above application, there are still some deficiencies:

[0004] The slag collecting pipe can only be manually held to absorb the slag on the table after the processing is completed. It cannot automatically absorb and clean the slag during the processing, which increases manual labor and is inconvenient to use.

[0005] Therefore, a gear hobbing machine for motor shaft processing is designed to optimize the above problems. Utility Model Content

[0025] Overall working principle: During the processing of the motor shaft, the suction hood 3 and the exhaust hood 4 are arranged relative to each other, which can play a certain blocking role during the shaft processing to avoid the splashing of debris. At the same time, the negative pressure fan 6 is started to generate negative pressure inside the collection box 5. The suction hood 3 draws a mixed gas containing debris from the outside, and the debris enters the collection box 5 for storage, while the gas discharged by the negative pressure fan 6 is discharged from the opposite side of the suction hood 3, forming a gas circulation, which can blow the debris toward the suction hood 3 to ensure the dust collection effect.

[0026] In this embodiment, a refrigeration box 9 is installed at the end of the processing bed 1 , a semiconductor refrigerator 10 is installed outside the refrigeration box 9 , and a conduit at the output end of the negative pressure fan 6 is connected to the interior of the refrigeration box 9 .

[0027] Partial working principle: During the gas circulation process, the gas passes through the interior of the refrigeration box 9, and the gas is cooled. During the shaft processing process, the shaft and the gear hobbing cutter can be cooled.

[0028] In this embodiment, partitions 14 are evenly arranged inside the refrigeration box 9 , and the partitions 14 are staggered on both sides of the refrigeration box 9 .

[0029] Partial working principle: By setting the partition 14, the residence time of the gas inside the refrigeration box 9 can be increased, ensuring the cooling effect of the gas.

[0030] In this embodiment, the exhaust hood 4 includes a rectangular plate 15, a cavity 16 and an exhaust hole 17. The rectangular plate 15 is vertically fixed to the side of the processing bed 1. Exhaust holes 17 are evenly opened on the side of the rectangular plate 15 close to the suction hood 3. A cavity 16 is opened in the middle position of the rectangular plate 15, and the exhaust hole 17 and the cavity 16 are connected.

[0031] Partial working principle: The cooled gas enters the cavity 16 and is then evenly discharged from the exhaust holes 17, increasing the blowing cleaning area and making it more practical.

[0032] In this embodiment, a pull rod 12 is vertically slidably provided on the top of the collection box 5 , and a brush plate 11 that fits against the side of the filter screen 8 is fixed to the bottom end of the pull rod 12 .

[0033] Partial working principle: When in use, the pull rod 12 can be pulled regularly to control the brush plate 11 to clean the surface of the filter 8 to ensure the permeability of the filter 8 and the negative pressure dust collection effect.

[0034] In this embodiment, a cross bar is fixed to the top of the pull rod 12 , a return spring 13 is provided between the brush plate 11 and the top of the collection box 5 , and the pull rod 12 passes through the inside of the return spring 13 .

[0035] Partial working principle: The use of the cross bar can prevent the pull rod 12 from entering the interior of the collection box 5, and the use of the reset spring 13 can ensure that the pull rod 12 can be quickly reset after losing the tension.

[0036] In this embodiment, a cleaning door is provided on the outside of the collection box 5 , and a transparent window is provided on the cleaning door.

[0037] Partial working principle: The storage amount of debris inside the collection box 5 is observed through the transparent window so that it can be processed in time.
