Description

Technical Field

[0001] This invention relates to the field of small rotor machining technology for Roots blowers, and more particularly to a device for machining curved surfaces of small rotors for Roots blowers. Background Technology

[0002] Roots blowers are positive displacement blowers. They work by using two lobe-shaped rotors moving relative to each other in a cylinder to compress and transport gas. These blowers have a simple structure and are easy to manufacture. They are widely used in aquaculture oxygenation, sewage treatment aeration, and cement conveying. They are also suitable for gas conveying and pressurization systems in low-pressure applications and can be used as vacuum pumps, etc.

[0003] The two impeller rotors are the most important and distinctive part of the Roots blower. The two impeller rotors are identical. When machining the impeller rotors, CNC machine tools are mainly used, which has a high degree of overall intelligence and good machining effect. However, in the actual machining process, some burrs will be generated on both sides of the impeller rotor. After machining, the impeller rotor needs to be ground. In addition, a large amount of debris and wastewater (wastewater refers to the clean water after the cooling water has washed the tool and raw material) will be generated during the machining process. The debris will fly everywhere, which poses certain safety hazards. There is no collection device for debris and wastewater, which increases the workload of post-machining cleaning. Therefore, a small rotor surface machining device for Roots blowers is provided. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as: during actual processing, certain burrs are generated on both sides of the impeller rotor; after processing, the impeller rotor needs to be ground; and during processing, a large amount of debris and wastewater (wastewater refers to the clean water after the cooling water has washed the cutting tool and raw material) are generated. The debris is scattered everywhere, posing certain safety hazards. There is no collection device for debris and wastewater. Therefore, this invention proposes a small rotor curved surface processing device for Roots blowers.

[0026] Reference Figures 1-9A small rotor surface machining device for Roots blowers includes a base 1. A top plate 3 is fixedly connected to the upper side of the base 1 via multiple support rods 2. A control center 19 is fixedly connected to the lower side of the top plate 3. A working rod 20 is installed on the lower side of the control center 19, and a working blade is fixedly connected to the lower side of the working rod 20.

The raw material to be processed is placed between the two tapered rods 11. Rotating the threaded rod 6 clamps and fixes the raw material between the two tapered rods 11. A fixing ring 12 is rotatably sleeved on the outer side of the tapered rod 11. A fixing block 13 is fixedly connected to the upper side of the fixed ring 12. A square hole 39 is provided on the side wall of the fixing block 13. A square rod 14 is slidably fitted inside the square hole 39. The square rod 14 passes through the square hole 39.

A grinding wheel is provided on the side of the worm gear 29 away from the square rod 14. 40. After the raw material is placed between the working rods 20, the grinding wheel 40 on the side wall of the worm wheel 29 contacts and connects with the side wall of the raw material. The working rod 20 is moved, and the working rod 20 drives the worm wheel 29 to rotate as a whole through the worm 18. The worm wheel 29 drives the grinding wheel 40 to rotate, thereby completing the cleaning operation of the burrs generated on the side wall of the raw material. The left and right sides of the working rod 20 are fixedly connected with the worm 18, and the worm 18 and the worm wheel 29 are meshed and connected. A limiting device is sleeved on the outer side of the working rod 20.

[0027] The limiting device includes a movable frame 8 fixedly sleeved on the outside of the working rod 20. The lower side of the movable frame 8 is open. A square frame 15 passes through the movable frame 8 and is slidably connected to it. A worm gear 18 is located inside the movable frame 8. Two water inlet pipes 21 are fixedly connected to the upper side of the movable frame 8. The two water inlet pipes 21 are arranged opposite to the working blade. Movable grooves 27 are provided on both lower sides of the movable frame 8. Movable plates 22 are slidably connected in the movable grooves 27. The movable plates 22 are connected to the bottom of the movable grooves 27 through a second spring 28. The movable frame 8 is used to perform a simple blocking operation on the debris, so that most of the debris is inside the movable frame 8, reducing the possibility of debris splashing and improving the overall safety of the device.

The receiving groove 26 is located on the lower side of the square frame 15 and is opposite to the square frame 15. An installation groove 32 is provided on the side of the receiving groove 26 away from the sliding plate 25. The sliding plate 25 passes through the installation groove 32 to complete the simple installation operation of the receiving groove 26. Then, the receiving groove 26 is used to complete the simple collection operation of debris and wastewater.

[0029] The sliding plate 25 is fixedly connected to the contact rod 35 in the mounting groove 32. There are clamping grooves 37 on both sides of the mounting groove 32. The clamping plate 36 is slidably connected in the two clamping grooves 37. The clamping plate 36 is set through the clamping groove 37. The clamping plate 36 and the contact rod 35 are set opposite to each other. The clamping plate 36 is connected to the bottom of the clamping groove 37 through the third spring 38. The contact rod 35 is locked in the mounting groove 32 by the clamping plate 36, thereby determining the movement trajectory between the square rod 14 and the receiving groove 26.

[0030] Two deep grooves 33 are symmetrically provided on the side of the receiving trough 26 away from the slide plate 25. Magnets 34 are fixedly connected in the two deep grooves 33. The magnets 34 are used to make the receiving trough 26 and the side wall of the raw material in close contact and connection, so as to better complete the collection of debris and wastewater.

[0031] The bottom of the receiving tank 26 is provided with multiple drainage holes 31. The drainage holes 31 are used to discharge the wastewater inside the receiving tank 26. At the same time, the drainage holes 31 will also perform a simple separation operation between the debris and the wastewater. The separated wastewater can be connected to the corresponding pipe and the water inlet pipe 21 to achieve a partial circulation effect and save water resources.

[0032] The upper side of the base 1 is provided with a sliding groove 9, and two sliding rods 10 are slidably connected in the sliding groove 9. The two sliding rods 10 are respectively fixedly connected to the fixed ring 12 to determine and limit the movement trajectory of the fixed ring 12.

[0033] A limiting plate 16 is fixedly connected to the side of the square rod 14 away from the working rod 20. The limiting plate 16 is connected to the first spring 17 and the fixing block 13 to complete the restriction operation of the initial position of the square rod 14, thereby making the connection between the side wall of the worm gear 29 and the raw material tighter, and thus better completing the cleaning operation of the rough edges of the side wall of the raw material.

[0034] In this invention, when it is necessary to process the small rotor inside the Roots blower, the specific operation is as follows: The raw material to be processed is placed between two conical rods 11. The threaded rod 6 is rotated, causing the conical rods 11 to move closer to each other until the conical rods 11 and the raw material are in close contact, thus completing the fixing operation of the raw material. At this time, the grinding wheel 40 on the side wall of the worm gear 29 contacts and connects with the side wall of the raw material. Under the action of the magnet 34, the receiving groove 26 contacts and connects with the side wall of the raw material. The control center 19 is then activated. The control center 19 moves the working blade up and down via the working rod 20, and also moves it left and right. Furthermore, the control center 19 rotates the rotating rod 23, which in turn rotates the rotating cylinder 5 via the belt 7. The rotating cylinder 5 then rotates the tapered rod 11 via the threaded rod 6. The tapered rod 11 rotates the raw material, initiating the processing operation. This is existing technology and will not be elaborated further. During the movement of the working blade, it first moves downwards, the square frame 15 enters the moving frame 8, and then the working blade... The moving plate 22 remains in close contact with the raw material during processing, and the second spring 28 is compressed. Most of the debris is contained within the moving frame 8. As the working rod 20 moves the working blade left and right, it drives the worm wheel 29 to rotate via the worm gear 18. The grinding wheel 40 on the side wall of the worm wheel 29 contacts the side wall of the raw material, removing burrs. When the working rod 20 moves left and right, it contacts and drives the square frame 15. The square frame 15 moves away from the raw material, the worm gear 29 disconnects from the raw material, and most of the debris follows the working blade into the receiving tank 26, thus completing the blocking and collection of debris. At the same time, during the processing, water is sprayed onto the side wall of the working blade through the water inlet pipe 21 to reduce the temperature of the raw material and the working blade. Then, most of the wastewater enters the receiving tank 26 and is discharged through the drain hole 31 on the side wall of the receiving tank 26, completing the simple collection of wastewater and circulating the filtered wastewater.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
