Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding equipment for processing aluminum castings. Background Technology

[0002] The casting industry occupies an important position in the machinery manufacturing industry. Aluminum castings are used in many machining processes because they are lighter. Grinding is an important step in the production of many parts, which directly affects the appearance and performance of the parts. In the current grinding process, dust removal equipment is used to remove the debris that flies during grinding in order to improve the quality of the grinding environment and reduce harm to the human body. However, the protection of the grinding equipment is lacking. The dust generated during grinding can easily enter the grinding equipment. When it enters the motor, it increases the probability of motor damage and affects its service life. Utility Model Content

[0003] This utility model provides a grinding device for processing aluminum castings. The metal shavings produced by grinding fall into a water tank through the gaps around the grinding table, thereby achieving the purpose of dust collection and avoiding the risk of metal dust scattering and damaging electrical components.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing aluminum castings, comprising: a grinding longitudinal plate, a water tank at the front end of the grinding longitudinal plate, a horizontal grinding table at the top of the water tank, and the grinding table spaced apart from the inner edge of the top of the water tank; a protective cover distributed on both sides and the top of the grinding longitudinal plate and connected to both sides of the water tank; a motor fixedly mounted below the water tank, the motor output shaft passing through the grinding longitudinal plate, and the motor electrically connected to a power source via a foot switch; a grinding spindle horizontally passing through the grinding longitudinal plate and corresponding to the top of the grinding table, a grinding head fitted to the front end of the grinding longitudinal plate, and a transmission mechanism connecting the grinding spindle and the motor output shaft at the rear end of the grinding longitudinal plate.

[0005] Preferably, the grinding spindle has a shaft groove at one end corresponding to the grinding table, the grinding head engages with the shaft groove via a splined shaft, and an open spring is provided between the shaft groove and the splined shaft.

[0006] Preferably, the grinding spindle includes an upper spindle and a lower spindle arranged longitudinally; the transmission mechanism includes driven pulleys disposed at the tail ends of the upper spindle and the lower spindle, and a pair of driving pulleys disposed on the motor output shaft, wherein each driving pulley and the corresponding driven pulley are respectively provided with a synchronous belt.

[0007] Preferably, the water tank is provided with a filter plate that slopes forward and downward, and the water tank is divided into an impurity tank and a clean water tank by the filter plate. The water tank is provided with a slag discharge valve at the bottom of the impurity tank.

[0008] Preferably, the motor is provided with a radiator on top, and the radiator is provided with heat dissipation fins extending into the clean water tank on top, and the heat dissipation fins are engaged with the bottom of the water tank by a sealing ring.

[0009] Preferably, a spray nozzle is fixedly provided on the top of the grinding longitudinal plate; a water pump is connected to the output shaft of the motor, the inlet of the water pump is connected to the bottom of the clean water tank, and the outlet of the water pump is connected to the spray nozzle through a pipe; the grinding spindle is provided with a water seal.

[0010] The beneficial effects of this utility model are as follows: the protective covers on both sides and top of the grinding head prevent the workpiece from being thrown away by the high-speed rotating grinding head, thus avoiding the risk of injury. Furthermore, during operation, the water tank contains a suitable amount of liquid, and the metal shavings produced during grinding fall into the water tank through the gaps around the grinding table, thereby achieving dust collection and preventing metal dust from scattering and damaging electrical components or causing an explosion risk. The motor drives two grinding spindles simultaneously, allowing workers to mount the grinding head on the upper or lower spindle for high or low-level grinding, meeting the grinding needs of different workpieces. To facilitate quick assembly and disassembly of the grinding head, corresponding slots are provided at the corresponding positions of the shaft groove and spline shaft, and self-locking is achieved through open springs on the shaft groove or spline shaft to ensure operational stability, similar to the principle of a half-shaft flange installation structure. The angle of the filter plate in the water tank is set so that the filtered metal shavings settle at the bottom of the impurity tank, and are later cleaned through a slag discharge valve. The heat dissipation fins extending into the clean water tank provide excellent heat dissipation for the motor, thus effectively ensuring its normal operation. A water pump delivers liquid from the clean water tank to the top of the grinding longitudinal plate, where it is sprayed onto the surface of the plate by spray nozzles. This creates a liquid film on the plate surface, collecting dust and allowing it to flow into the water tank for filtration and collection. This reduces the amount of metal dust spreading and prevents damage to the motor and other electrical components. Attached Figure Description

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] according to Figure 1 , Figure 2 As shown, a grinding device for processing aluminum castings includes: a grinding longitudinal plate 1, a water tank 2 at the front end of the grinding longitudinal plate 1, a horizontal grinding table 3 at the top of the water tank 2, and the grinding table 3 being spaced apart from the inner edge of the top of the water tank 2; a protective cover 4, distributed on both sides and the top of the grinding longitudinal plate 1 and connected to both sides of the water tank 2; a motor 5, fixedly installed below the water tank 2, with its output shaft passing through the grinding longitudinal plate 1, and electrically connected to a power source via a foot switch 6; and a grinding spindle, horizontally passing through the grinding longitudinal plate 1 and corresponding to the top of the grinding table 3, with a grinding head 7 fitted to the front end of the grinding longitudinal plate 1, and a transmission mechanism connecting the grinding spindle and the output shaft of the motor 5 at the rear end of the grinding longitudinal plate 1.

[0017] With the above setup, the worker controls the motor 5 via a foot switch 6, which in turn drives the grinding spindle to rotate at high speed under the action of the transmission mechanism. The grinding head 7, mounted on the grinding spindle, is used to grind burrs, sprues, and other imperfections on the edges of the workpiece, thereby meeting the processing requirements of the workpiece. The protective covers 4 on both sides and the top of the grinding head 7 prevent the workpiece from being blown away by the high-speed rotating grinding head 7, thus avoiding the risk of injury. In addition, during operation, the water tank 2 contains an appropriate amount of liquid. Metal shavings produced during grinding fall into the water tank 2 through the gaps around the grinding table 3, thereby achieving the purpose of dust collection and preventing metal dust from scattering and damaging electrical components or causing an explosion risk.

[0018] The grinding spindle has a shaft groove 13 at one end corresponding to the grinding table 3. The grinding head 7 cooperates with the shaft groove 13 via a splined shaft 14, and an open spring is provided between the shaft groove 13 and the splined shaft 14. The grinding spindle includes an upper spindle 8 and a lower spindle 9 arranged longitudinally. The transmission mechanism includes driven pulleys 10 disposed at the tail ends of the upper spindle 8 and the lower spindle 9, and a pair of driving pulleys 11 disposed on the output shaft of the motor 5. A synchronous belt 12 is provided between each driving pulley 11 and the corresponding driven pulley 10.

[0019] With the above configuration, motor 5 drives two grinding spindles simultaneously, so the worker can mount the grinding head 7 on the upper spindle 8 or the lower spindle 9 for high or low grinding work to meet the grinding needs of different workpieces. In order to meet the quick disassembly and assembly of the grinding head 7, the corresponding positions of the shaft groove 13 and the spline shaft 14 are respectively provided with slots, and the open spring on the shaft groove 13 or the spline shaft 14 is used for locking to ensure the stability of the operation. Its principle is similar to the mounting structure of automobile half-shaft flange.

[0020] The water tank 2 is provided with a filter plate 16 that is inclined forward and downward. The water tank 2 is divided into an impurity tank 17 and a clean water tank 18 by the filter plate 16. The bottom of the water tank 2 corresponding to the impurity tank 17 is provided with a slag discharge valve 19.

[0021] In this setup, the angle of the filter plate 16 is set so that the metal debris intercepted by the filter settles at the bottom of the impurity tank 17, and is later cleaned by the slag discharge valve 19.

[0022] In addition, the motor 5 is equipped with a radiator 20 on its top, and the radiator 20 has heat dissipation fins 21 extending into the water tank 2 of the clean water tank 18 on its top. The heat dissipation fins 21 are engaged with the bottom of the water tank 2 by a sealing ring. The heat dissipation fins 21 extending into the water tank 2 of the clean water tank 18 provide good heat dissipation for the motor 5, thus effectively ensuring the normal operation of the motor 5.

[0023] The top of the grinding longitudinal plate 1 is fixedly equipped with a spray nozzle 22; the output shaft of the motor 5 is connected to a water pump 23, the inlet of the water pump 23 is connected to the bottom of the clean water tank 18 water tank 2, and the outlet of the water pump 23 is connected to the spray nozzle 22 through a pipe; the grinding main shaft is equipped with a water seal.

[0024] In this setup, the water pump 23 pumps the liquid in the clean water tank 18 to the top of the grinding plate 1, and sprays it onto the surface of the grinding plate 1 through the spray head. Finally, a liquid film is formed on the surface of the grinding plate 1, which collects the dust and allows the dust to flow into the water tank 2 with the liquid for filtration and collection, reducing the amount of metal dust diffusion and avoiding damage to electrical components such as the motor 5.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
