Description

Technical Field

[0001] This utility model belongs to the field of casting grinding technology, specifically relating to a grinding device for a cleaning machine housing casting. Background Technology

[0002] In the production process of some cleaning machine housings, certain parts need to be formed by casting. However, the surface of cast parts has many burrs and low roughness, so the castings need to be ground to ensure they meet production requirements.

[0003] The most common grinding method currently available is the angle grinder, which is small in size and highly flexible, making it suitable for grinding curved or angular areas on the surface of castings. However, since the angle grinder needs to be held by hand during use, and its vibration frequency is relatively high, it is easy to slip out of the operator's hand. On the one hand, this is not very safe and poses a safety risk. On the other hand, the debris generated during grinding not only pollutes the environment, but also easily gets into the eyes. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the casting of a cleaning machine housing, which can prevent the angle grinder from slipping out of the hand during grinding, and can also collect the debris generated during grinding, thereby increasing the cleanliness of the grinding environment.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A grinding device for a washing machine housing casting includes an angle grinder. One end of the angle grinder has a transmission housing. A rotating shaft is rotatably connected to the side wall of the transmission housing. A grinding wheel is mounted on the side wall of the rotating shaft. An anti-drop component is mounted on the side wall of the angle grinder. A filter housing is fixedly connected to the top surface of the transmission housing. A partition is fixedly connected to the inner wall of the filter housing. The space between the partition and the filter housing is a material guiding chamber. A baffle is mounted inside the material guiding chamber. An impeller is fixedly connected to the top of the rotating shaft below the partition. A collecting component is provided on the upper side of the partition. A corrugated pipe is fixedly connected to the side wall of the filter housing below the partition. A tapered pipe is fixedly connected to the other end of the corrugated pipe.

[0007] The anti-fall-off component includes two clamps fixedly connected to the side wall of the angle grinder. A connecting ring is fixedly connected to the side wall of the clamp, and a restraining strap is fixedly connected inside one side of the connecting ring. The other end of the restraining strap passes through the connecting ring.

[0008] The sidewall of the restraint strap is fixedly connected with Velcro, which has a hook side and a loop side.

[0009] A round shaft is fixedly connected to the side wall of the baffle, and the other end of the round shaft is rotatably connected to the inner wall of the filter shell. A torsion spring is assembled on the side wall of the round shaft.

[0010] The collection assembly includes a collection box disposed on the upper side of the partition, the top of the collection box is open, the side wall of the filter shell is provided with a through groove corresponding to the collection box, the inner wall of the collection box is fitted with a filter screen, and a guide plate is fixedly connected to the inner wall of the collection box near the guide cavity, the guide plate is inclined.

[0011] The side wall of the collection box has several air holes.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a grinding device for the casting of a cleaning machine housing. Through the cooperation of an angle grinder, an anti-fall-off component, a filter shell, and a collection component, when the angle grinder is held by hand, a restraint strap can be used to keep it close to the hand to prevent it from falling off the hand when the angle grinder vibrates, thus avoiding safety hazards.

[0021] To make the purpose 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 implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-5 As shown, a grinding device for a washing machine housing casting includes an angle grinder 1. A transmission housing 7 is provided at one end of the angle grinder 1. A rotating shaft 9 is rotatably connected to the side wall of the transmission housing 7. A grinding wheel 6 is mounted on the side wall of the rotating shaft 9. An anti-fall-off component is mounted on the side wall of the angle grinder 1. A filter housing 8 is fixedly connected to the top surface of the transmission housing 7. A partition 20 is fixedly connected to the inner wall of the filter housing 8. The space between the partition 20 and the filter housing 8 is a material guiding chamber. A baffle 11 is mounted in the material guiding chamber. An impeller 10 is fixedly connected to the top of the rotating shaft 9 below the partition 20. A collection component is provided on the upper side of the partition 20. A corrugated pipe 18 is fixedly connected to the side wall of the filter housing 8 below the partition 20. A tapered pipe 19 is fixedly connected to the other end of the corrugated pipe 18.

[0023] like Figure 1 As shown, the anti-fall-off component includes two clamps 2 fixedly connected to the side wall of the angle grinder 1. A connecting ring 3 is fixedly connected to the side wall of the clamp 2. A restraining strap 4 is fixedly connected inside one side of the connecting ring 3, and the other end of the restraining strap 4 passes through the connecting ring 3. A hook and loop fastener 5 is fixedly connected to the side wall of the restraining strap 4. The hook and loop fastener 5 has a hook side and a loop side.

[0024] The anti-drop component allows for adjustment of the length of the restraint strap 4 according to the hand size of different users. All Velcro straps 5 are located on the same outer side of the restraint strap 4. After the restraint strap 4 passes through the connecting ring 3, it can be tightened so that the hook side and the napped side of the Velcro strap 5 correspond to each other, thus fixing the restraint strap 4 and preventing the angle grinder 1 from vibrating too much during the grinding process, which could cause the strap to slip off the user's hand.

[0025] like Figure 4 As shown, a round shaft 16 is fixedly connected to the side wall of the baffle 11, and the other end of the round shaft 16 is rotatably connected to the inner wall of the filter shell 8. A torsion spring 17 is assembled on the side wall of the round shaft 16. When the baffle 11 is impacted by the airflow, it opens, and the torsion spring 17 is compressed, allowing debris and impurities to easily enter the collection box 12 through the guide chamber. When the angle grinder 1 stops running, the airflow disappears, and the baffle 11 is reset and closed by the force of the torsion spring 17, which can effectively prevent impurities from flowing back down.

[0026] like Figure 3 and Figure 5 As shown, the collection assembly includes a collection box 12 disposed on the upper side of the partition 20. The top of the collection box 12 is open. The side wall of the filter shell 8 is provided with a through groove corresponding to the collection box 12. The inner wall of the collection box 12 is fitted with a filter screen 13. A guide plate 14 is fixedly connected to the inner wall of the collection box 12 near the guide cavity. The guide plate 14 is inclined.

[0027] The side wall of the collection box 12 has several air holes 15.

[0028] The principle of the collection component is similar to that of a vacuum cleaner collecting dust, and will not be described in detail in this solution. In addition, in order to increase the stability between the collection box 12 and the filter shell 8, the collection box 12 and the filter shell 8 can be connected by magnetic attraction, bolt connection, snap-fit ​​or other methods.

[0029] The working principle of this utility is as follows: When grinding the casting, first adjust the position of the bellows 18 so that the tapered tube 19 corresponds to the position where grinding chips are generated. Then hold the angle grinder 1 and adjust the tightness of the restraint strap 4 so that it fits tightly against the operator's hand. Use Velcro 5 to fix it to reduce the risk of the angle grinder 1 falling.

[0030] Then, the angle grinder 1 is started, and the grinding wheel 6 is rotated by the rotating shaft 9 to grind the casting. At the same time, the rotating shaft 9 drives the impeller 10 to rotate, and the impeller 10 generates suction. The airflow enters the lower side of the baffle 20 through the bellows 18. The airflow impact force blows the baffle 11 upward. At the same time, the torsion spring 17 is compressed. The debris generated during grinding enters the guide chamber with the airflow and enters the collection box 12 through the inclined surface of the guide plate 14. The airflow passes through the filter screen 13 and is discharged from the air hole 15. The debris and impurities are blocked by the filter screen 13 in the collection box 12, achieving the effect of dust collection and increasing the cleanliness and safety of the working environment.

[0031] 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 principles 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 art.
