Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, and specifically relates to a gear hobbing machine. Background Technology

[0002] The gear hobbing machine is one of the most widely used gear processing machine tools. It can cut spur gears, helical gears, worm gears, sprockets, etc. It is a gear processing machine tool that uses hobs to process spur gears, helical gears, herringbone gears, and worm gears using the generating method. When using specially made hobs, this type of machine tool can also process splines, sprockets, and other workpieces with special tooth profiles.

[0003] Gear machining utilizes the relative motion between a hob and a workpiece to process gears. During this process, significant friction and heat are generated between the hob and the workpiece. Currently, most hob-machined products use cutting fluid directly sprayed onto the workpiece for lubrication and temperature reduction. During the use of cutting fluid, factors such as pump circulation, spraying, intense impact with the high-speed rotating tool or workpiece, and high-temperature evaporation generate oil mist exhaust gas. This oil mist exhaust gas mainly consists of oil mist and organic waste gas generated by the evaporation of cutting fluid due to heating. Untreated oil mist cutting fluid fumes contain various harmful substances, including heavy metal ions and benzene, which can harm human health. Utility Model Content

[0004] The purpose of this invention is to provide a gear hobbing machine that can effectively adsorb and filter oil mist exhaust gas generated during the cutting process.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a gear hobbing machine includes a housing 1, a hobbing machine body 2 disposed inside the housing 1, a coolant tank 3 fixedly connected to the bottom of one side of the housing 1, a water pump 6 fixedly connected to the housing of the hobbing machine body 2, an oil supply pipe 5 connected to the water inlet of the water pump 6 and one end of the oil supply pipe 5 connected to the coolant tank 3, a telescopic pipe fixed to the housing of the hobbing machine body 2 on one side of the water outlet of the water pump 6 and a nozzle 7 connected to one end of the telescopic pipe, and a filter box 11 fixedly connected to one side of the top of the housing 1, and an adsorption assembly disposed inside the filter box 11.

[0022] Specifically, the bottom of the housing 1 is equipped with a base plate for connecting the filter box 11 and the fan 15; a pull-out door and controller are provided on one side of the housing 1, which can flexibly open or close the housing 1. This design allows the mist generated when the hob moves relative to the workpiece to be effectively locked inside the housing 1, thereby avoiding the diffusion of mist and environmental pollution. The controller is set to make it easier for employees to operate the on / off state of the device, ensuring ease of operation and safety. Metal chips generated during the cutting process between the hob and the workpiece fall together with the cutting fluid into the top of the hobbing machine body 2, and flow into the coolant tank 3 through the hobbing machine body 2. The coolant is pumped from the coolant tank 3 through the oil pipe 5 by the water pump 6 to the nozzle 7 and sprayed onto the workpiece again; the design of the telescopic tube allows it to adapt to hobs and workpieces of different heights.

[0023] like Figure 1 and Figure 4 As shown, the adsorption assembly includes an air supply pipe 10 connected to the top of the filter box 11. One end of the air supply pipe 10 extends into the inner cavity of the box body 1 and is connected to a mist suction hopper 9. Filter screens 13 and activated carbon adsorption screens 12 are sequentially inserted in the filter box 11 along the left-right direction. Multiple dry adsorption balls 14 are arranged between the filter screens 13 and the activated carbon adsorption screens 12. A fan 15 is fixed on one side of the filter box 11, and the air inlet of the fan 15 is connected to the filter box 11.

[0024] Under the suction of the filter box 11, the mist suction bucket 9 is used to suck in the oil mist exhaust gas generated when the roller cutter and the workpiece move relative to each other inside the box 1. Then, the air supply pipe 10, together with the mist suction bucket 9, transports the oil mist exhaust gas to the filter box 11. The oil mist exhaust gas is then purified by the filtration of the filter screen 13 and the activated carbon adsorption screen 12, and the adsorption between multiple dry adsorption balls 14. Finally, it is discharged by the fan 15.

[0025] like Figure 2 As shown, an auxiliary filter 4, which works in conjunction with the gear hobbing machine body 2, is embedded on the top of one side of the coolant tank 3.

[0026] Specifically, the cutting fluid is sprayed directly between the hob and the workpiece. The metal chips generated during the cutting process fall into the hobbing machine body 2 along with the cutting fluid and flow into the coolant tank 3. The auxiliary filter screen 4 is designed to filter the metal chips in the cutting fluid.

[0027] like Figure 2 As shown, the top of the filter box 11 has an inlet hole for use with the dry adsorption ball 14, and a sealing plug is inserted into the top of the inlet hole.

[0028] The design of the inlet hole makes it easy for staff to place the dry adsorption ball 14 into the filter box 11, while the design of the sealing plug ensures that the filter box 11 maintains good sealing during operation.

[0029] like Figure 1 As shown, the front of the filter box 11 is provided with an opening and closing door that works in conjunction with the dry adsorption ball 14, the filter screen 13 and the activated carbon adsorption screen 12.

[0030] Specifically, an opening and closing door is installed on one side of the filter box 11, which allows staff to easily open and replace the adsorption components inside the filter box 11, improving the convenience of adsorption component maintenance.

[0031] like Figure 2 As shown, a fixing ring 8 is fixed on the housing of the gear hobbing machine body 2 to cooperate with the telescopic tube.

[0032] The retaining ring 8 is designed to stabilize the telescopic tube and the nozzle 7, thereby maintaining the stability of the nozzle 7 during the spraying of cutting fluid.

[0033] The working principle of this utility model is as follows: The operator uses the gear hobbing machine body 2 to process the gear. During the cutting process, the metal chips generated fall onto the base of the gear hobbing machine body 2 along with the cutting fluid. After being filtered by the auxiliary filter screen 4, they flow into the coolant tank 3. Then, the water pump 6 drives the cutting fluid in the coolant tank 3 to be transported to the nozzle 7 through the oil supply pipe 5 for circulating spraying. At the same time, the oily fumes generated during the spraying process are transported to the filter box 11 by the suction of the filter box 11, the mist suction bucket 9 and the air supply pipe 10. The oily fumes are filtered by the activated carbon adsorption net 12 and the filter screen 13, and the oily fumes are adsorbed by the dry adsorption ball 14. Finally, the fumes are discharged by the fan 15, thus completing the filtration and discharge of the oily fumes in the box 1.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
