A gear hobbing machine for automobile half-shaft blanks

Abstract

This utility model relates to the field of gear hobbing machine technology, specifically to a gear hobbing machine for automotive half-shaft blanks. It includes a gear hobbing machine body and a waste cleaning assembly. The waste cleaning assembly includes a baffle, a cleaning brush, a drain port, a positioning slide rail, a filter tower, and a recovery tank. The baffle can be slidably closed, blocking cutting debris and cutting fluid from splashing during half-shaft machining. Some debris and cutting fluid fall directly into the filter tower through the drain port, where the debris is filtered. The cutting fluid then enters the recovery tank after passing through the filter tower for use in subsequent half-shaft machining. After half-shaft machining is completed, the cleaning brush is activated, sliding within the gear hobbing machine body to push residual debris and cutting fluid into the drain port for filtration by the filter tower. This process effectively treats and recovers the debris and cutting fluid generated during gear hobbing, making it more environmentally friendly than traditional direct discharge methods. The positioning slide rail is used to fix the filter tower below the drain port.

The tank body is located at the bottom of the tower, the recycling pump is mounted on the outside of the tank body, and the circulation pipeline is connected to the recycling pump and located on one side of the recycling pump.

[0011] This utility model discloses a gear hobbing machine for automotive half-shaft blanks. The gear hobbing machine body is used for gear hobbing of automotive half-shaft blanks, and the waste cleaning component is used for cleaning and recycling cutting waste. Specifically, the baffle can be slidably closed to block cutting debris and cutting fluid splashed during the machining of the half-shaft by the gear hobbing machine body. Some debris and cutting fluid fall directly into the filter tower through the drain port. After the debris is filtered by the filter tower, the cutting fluid enters the recovery tank after passing through the filter tower. The cutting fluid is recovered in the recovery tank and can be used for subsequent machining of the half-shaft by the gear hobbing machine body.

This method is more environmentally friendly than traditional direct discharge. The positioning slide rail is used to fix the filter tower below the drain port, solving the problem of direct discharge of chips and cutting fluid without treatment, which pollutes the working environment.

[0018] Please see Figures 1 to 3 This utility model provides a gear hobbing machine for automotive half-shaft blanks, including a gear hobbing machine body 1 and a waste cleaning assembly 2. The waste cleaning assembly 2 is disposed on one side of the gear hobbing machine body 1. The waste cleaning assembly 2 includes a baffle 3, a cleaning brush 4, a discharge port 5, a positioning slide rail 6, a filter tower 7, and a recycling tank 8. The baffle 3 is mounted on one side of the gear hobbing machine body 1, the cleaning brush 4 is mounted on the gear hobbing machine body 1 and located inside the baffle 3, the discharge port 5 is disposed on one side of the gear hobbing machine body 1, the positioning slide rail 6 is fixedly connected to the gear hobbing machine body 1 and located at the bottom of the discharge port 5, the filter tower 7 is mounted on one side of the positioning slide rail 6, and the recycling tank 8 is disposed at the bottom of the filter tower 7.

[0019] In this embodiment, the gear hobbing machine body 1 is used to perform gear hobbing on the half-shaft blank. The structure of the gear hobbing machine body 1 is described in patent CN210172720U, "A gear hobbing machine (spraying equipment not shown)". The waste cleaning component 2 is used to clean and recover the cutting waste. Specifically, the baffle 3 can be slidably closed, thereby blocking the cutting debris and cutting fluid splashed during the half-shaft machining process on the gear hobbing machine body 1. Some debris and cutting fluid fall directly into the filter tower 7 through the drain port 5. After the filter tower 7 filters the debris, the cutting fluid enters the recovery tank 8 after passing through the filter tower 7, where the cutting fluid is recovered. The cutting fluid can be used for subsequent processing of the half shaft by the gear hobbing machine body 1. After the half shaft is processed, the worker starts the cleaning brush 4 through the controller, so that the cleaning brush 4 slides inside the gear hobbing machine body 1, pushing the residual chips and cutting fluid into the discharge port 5, and then filtering it through the filter tower 7. This allows the chips and cutting fluid generated by the gear hobbing machine body 1 to be treated and recycled, which is more environmentally friendly than the traditional direct discharge method. The positioning slide rail 6 is used to fix the filter tower 7 below the discharge port 5, which solves the problem of direct discharge of chips and cutting fluid without treatment, which pollutes the working environment.

[0021] In this embodiment, the electric push rod 10 is a commercially available electric telescopic rod. It is activated by a controller to push the brush plate 9 to slide on the gear hobbing machine body 1, thereby pushing the residual debris and cutting fluid into the discharge port 5.

[0022] Furthermore, the positioning slide rail 6 includes a slide rail body 11 and a positioning magnetic block 12. The slide rail body 11 is fixedly connected to the gear hobbing machine body 1 and is located on one side of the gear hobbing machine body 1. The positioning magnetic block 12 is fixedly connected to the slide rail body 11 and is located on one side of the slide rail body 11.

[0023] In this embodiment, the slide rail body 11 provides installation and support conditions for the filter tower 7. The positioning magnet 12 is used to adsorb and fix the filter tower 7 on the slide rail body 11. When the filter tower 7 is disassembled and replaced, the filter tower 7 can be pulled out of the slide rail body 11 to realize the disassembly and assembly of the filter tower 7. The operation is convenient and quick.

[0024] Furthermore, the filter tower 7 includes a tower 13, a filter screen 14, and a filter cotton 15. The tower 13 is slidably connected to the slide rail body 11 and is located on one side of the slide rail body 11. The filter screen 14 is assembled on one side of the tower 13, and the filter cotton 15 is assembled on one side of the tower 13.

[0025] In this embodiment, the tower 13 provides a position for the filter screen 14 and the filter cotton 15, which are multiple and are sequentially laid inside the tower 13 to filter out debris from the cutting fluid.

[0026] Furthermore, the recycling tank 8 includes a tank body 16, a recycling pump 17, and a circulation pipeline 18. The tank body 16 is located at the bottom of the tower 13, the recycling pump 17 is mounted on the outside of the tank body 16, and the circulation pipeline 18 is connected to the recycling pump 17 and located on one side of the recycling pump 17.
