[0018] 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.

[0019] like Figures 1-2 As shown, a worm gear milling machine includes: a slide rail 1, a clamping machine 2 and a platform 4 slidably disposed at the top two ends of the slide rail 1, the end of the clamping machine 2 clamps the worm gear 3 to be processed, and a tool setting box 5 is disposed on the top of the platform 4; The slide rail 1 is used to carry the clamping machine 2 and the platform 4. During milling, the two need to be slid together to make the milling process smooth. The clamping machine 2 is used to clamp the blank of the worm gear 3 to be processed. The tool setting is performed by moving the tool setter box 5 up, down, left and right, and tilting.

[0020] A cyclone milling roller 501 is rotatably mounted inside the tool box 5. The worm gear 3 to be processed extends into the interior of the cyclone milling roller 501. Multiple milling cutters 502 are mounted on the side of the cyclone milling roller 501 near the worm gear 3 to be processed.

[0021] The tool setter box 5 is equipped with a drive motor on its top, which is connected to the cyclone milling roller 501 via a conveyor belt. The drive motor provides power for the rotation of the cyclone milling roller 501 during milling. When the cyclone milling roller 501 rotates, the position of the milling cutter 502 is changed by moving the tool setter box 5, thereby milling the worm gear 3 to be processed into threads.

[0022] See attached document Figures 3-5A front ring 6 and a rear cover 7 are fixedly installed on both sides of the tool box 5. A baffle 602 is detachably installed on one end of the front ring 6 near the worm gear 3 to be machined. A feed window is opened on the baffle 602 near the worm gear 3 to be machined. A coolant pump 603 is fixedly installed on one side of the front ring 6. The output end of the coolant pump 603 extends into the interior of the front ring 6 for spraying coolant onto the milling area. Among them, the front ring 6 and the rear cover 7 enclose the front and rear ends of the cyclone milling roller 501 to form a relatively closed space, preventing milling debris and coolant from splashing, so that it can only move within the sealed space. The feed window of the baffle 602 needs to be cut out according to the diameter and size of the worm gear 3 to be processed, so it needs to be disassembled and replaced. Its material is mostly plastic and other materials. The coolant pump 603 can draw in external coolant through pipes and spray it onto the milling area for cooling, keeping the coolant inside a closed space.

[0023] The bottom of the front ring 6 and the rear cover 7 are respectively provided with a drop pipe 601 and a discharge pipe 701 for discharging milling chips; When milling chips and coolant are confined in a closed space, they need to be collected through drop pipe 601 and discharge pipe 701. Both pipes have collection boxes at their bottoms for recycling chips and coolant.

[0024] Inspection ports are provided on one side of both the feed pipe 2 701 and the front ring 6; The inspection port is designed to prevent debris from accumulating and causing blockage in the feed pipe 701. When blocked, the inspection port can be used to clear the blockage. Under normal circumstances, the inspection door is closed, connected by a hinge, and equipped with a lock.

[0025] According to the above structure, the front ring 6 and the rear cover 7 enclose the front and rear ends of the cyclone milling roller 501 to prevent milling debris and coolant from splashing, and control the milling debris and coolant in a relatively closed space before uniform discharge and recycling.

[0026] See attached document Figures 3-7 The rear cover 7 has a guide plate 703 inside, and the end of the guide plate 703 away from the polygonal fixing pin 702 extends into the interior of the cyclone milling roller 501. The guide plate 703 is used to guide the milling debris inside the cyclone milling roller 501 into the rear cover 7, thereby preventing it from accumulating inside the cyclone milling roller 501.

[0027] Two polygonal fixing pins 702 are fixedly installed at the bottom of the rear cover 7, and the two polygonal fixing pins 702 are arranged symmetrically in the horizontal direction; a polygonal insertion hole 704 is opened at the end of the guide plate 703, and the polygonal insertion hole 704 is inserted and connected to one of the polygonal fixing pins 702. The purpose of designing two polygonal fixing pins 702 is to prevent the cyclone milling roller 501 from reversing. When reverse milling is required, the guide plate 703 is removed from one polygonal fixing pin 702 and inserted into the other polygonal fixing pin 702 with the tilt angle symmetrical to the original. Then, the debris generated by the reverse rotating cyclone milling roller 501 can be guided.

[0028] The polygonal fixing pin 702 is inclinedly disposed inside the cyclone milling roller 501, and the angle between the guide plate 703 and the central axis of the rear cover 7 is 30-60 degrees. When the debris is generated, it will come into contact with the inner wall of the cyclone milling roller 501 under the action of gravity. At this time, the rotating cyclone milling roller 501 will carry the debris and move vertically towards the central axis inside it. The direction of movement is the rotation direction of the cyclone milling roller 501. When the debris comes into contact with the guide plate 703 during the movement. Since the guide plate 703 is set relatively parallel to the central axis of the cyclone milling roller 501, the guide plate 703 can block the movement of debris. The guide plate 703 and the central axis of the cyclone milling roller 501 have a certain angle, which makes the resistance at both ends of the guide plate 703 different. At this time, the debris will move towards the end of the guide plate 703 with less resistance, that is, the end closer to the rear cover 7, until it enters the interior of the rear cover 7. When the polygonal fixing pin 702 has a large tilt angle, it needs to be longer, which reduces its structural stability; when the tilt angle is small, the guiding effect is reduced.

[0029] The bottom of the guide plate 703 is attached to the inner wall of the cyclone milling roller 501, and the bottom of the guide plate 703 is provided with multiple liquid suction holes 705. In the cyclone milling roller 501, the coolant inside is generally deposited at the bottom, and the suction hole 705 is located at the bottom to facilitate the suction of coolant.

[0030] The end of the guide plate 703 is connected to a suction tube, and a negative pressure chamber 707 is opened inside the guide plate 703. A connecting hole 706 is opened at the polygonal insertion hole 704 of the guide plate 703 to connect the negative pressure chamber 707. The suction pipe is connected to a liquid pump, which can provide negative pressure to the inside of the negative pressure chamber 707 through the suction pipe. Due to structural reasons, the guide plate 703 at the polygonal insertion hole 704 needs to have a connecting hole 706 to connect the negative pressure chamber 707 with the suction pipe.

[0031] The negative pressure chamber 707 is connected to multiple suction holes 705, the diameter of which is 1-3 mm; The negative pressure of the negative pressure chamber 707 is transmitted through the liquid suction hole 705, thereby drawing in the coolant inside the cyclone milling roller 501. The small diameter of the liquid suction hole 705 can prevent debris from being sucked in and thus causing blockage, while providing greater suction to prevent the coolant from being unable to be drawn in due to insufficient suction.

[0032] Multiple suction holes 705 are concentrated at one end of the guide plate 703 away from the polygonal insertion hole 704, while suction holes 705 are dispersed at the middle position of the guide plate 703 and the end near the polygonal insertion hole 704.

[0033] During tool setting, the tool setter 5 slightly tilts the cyclone milling roller 501, causing coolant to concentrate inside the cyclone milling roller 501 near the milling cutter 502. The concentrated suction holes 705 can more quickly draw out the accumulated coolant. Because the cyclone milling roller 501 rotates at a very high speed, the tilted cyclone milling roller 501 has little impact on chips, so it will not affect the guide plate 703's guidance of chips. According to the above structure, the function of the guide plate 703 is to guide the milling debris inside the cyclone milling roller 501 into the interior of the rear cover 7, thereby preventing it from accumulating inside the cyclone milling roller 501. The rotating milling roller 501 carries debris inside. When the debris comes into contact with the guide plate 703 during its movement, the guide plate 703 can block the movement of the debris. The debris will then move towards the end of the guide plate 703 where the resistance is smaller, until it enters the rear cover 7. Then the debris is discharged through the discharge pipe 701.

[0034] The working principle of this utility model is as follows: the front ring 6 and the rear cover 7 seal the front and rear ends of the cyclone milling roller 501 to prevent milling debris and coolant from splashing, and control the milling debris and coolant in a relatively closed space. The guide plate 703 guides the milling debris inside the cyclone milling roller 501 into the interior of the rear cover 7, thereby preventing it from accumulating inside the cyclone milling roller 501. The rotating cyclone milling roller 501 carries the debris inside. When the debris comes into contact with the guide plate 703 during its movement, the guide plate 703 can block the movement of the debris. The debris will then move towards the end of the guide plate 703 where the resistance is smaller, until it enters the rear cover 7 and is then discharged through the discharge pipe 701.

[0035] 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.
