Description

Technical Field

[0001] The present application relates to the technical field of grinding processing, and more specifically, to an aluminum alloy motor housing processing device and a processing method. Background Art

[0002] Motor housings made of aluminum alloy have the advantages of light weight, excellent heat dissipation performance, strong corrosion resistance, high appearance quality and good electromagnetic shielding effect, and have been widely used in the field of motor manufacturing.

[0003] During the production process of the motor metal casing, grinding can remove burrs, scratches and other defects on the casing surface, making the surface smoother and flatter, and significantly improving the surface quality of the motor casing.

[0004] When existing grinding equipment performs grinding processing on aluminum alloy motor housings, in order to avoid the metal dust generated during the grinding process from polluting the operating environment, negative pressure adsorption is mostly used to adsorb and filter the metal powder on the filter plate. However, this metal powder adsorption treatment method, when a large amount of metal powder is adsorbed on the filter plate, is likely to cause the flow velocity of the negative pressure airflow to decrease, so that the suction force of the negative pressure adsorption system is weakened, and the metal dust cannot be effectively extracted from the processing area, increasing the dust concentration in the air. In addition, if the filter is stopped to clean the filter during the motor housing processing, it will undoubtedly interrupt the grinding process and reduce the production efficiency of the motor housing.

[0005] In view of this, we propose aluminum alloy motor housing processing equipment and processing method. Summary of the invention

[0016] The technical solution of the present application provides a processing method for aluminum alloy motor housing processing equipment, comprising the following steps: S1. The metal dust generated during the grinding process of the motor housing surface by the grinding processing structure is continuously sucked into the inlet component under the suction force of the vacuum pump in the negative pressure chip cleaning unit; S2. The dust is conducted to the lower cavity inside the negative pressure collection box through the common conduit in the inlet hole component and is intercepted and filtered by the filter.

When the filter in the lower chamber is clogged with debris and dust, the air pressure in the space on the leeward side of the filter in the lower chamber gradually decreases and drives the plug rod in the conical groove to move downward; S5, when the downwardly moving plug rod drives the forced valve plate in the nozzle member to deflect downward from the initial horizontal state, the ejector rod originally resting against the surface of the forced valve plate also moves downward under the elastic force of the sliding seat member; S6, one of the switch terminals moving with the sliding seat contacts the other switch terminal located below it and triggers the solenoid valve in the inlet component to open; S7. Under the negative pressure suction of the vacuum pump, metal dust and metal debris enter the upper chamber through the spare conduit, and are filtered by the filter screen in the upper chamber. The filtered gas is then ejected from the nozzle.

[0017] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. The metal dust generated during the grinding process on the surface of the aluminum alloy motor housing is continuously sucked into the inlet component under the suction of the vacuum pump, and the dust is conducted to the lower cavity through the common conduit and intercepted and filtered by the filter. The filtered gas is transmitted from the output end of the vacuum pump to the nozzle member in the exhaust structure. The high-pressure airflow ejected by the nozzle member then sprays the metal debris generated during the grinding process of the motor housing into the inlet component, and the debris is discharged through the common guide. The air in the air is then conducted to the lower chamber through the tube. When the filter in the lower chamber is clogged with debris and dust, the air pressure in the space on the leeward side of the filter in the lower chamber gradually decreases and drives the plug rod to move downward. When the downward-moving plug rod drives the forced valve plate in the nozzle member to deflect downward from the initial horizontal state, the ejector rod originally resting on the surface of the forced valve plate also moves downward under the elastic force of the sliding seat member. In the process of the ejector rod moving downward, the two switch terminals come into contact and trigger the solenoid valve in the inlet member to open, thereby ensuring the effect of sucking away the metal powder generated during the cutting process of the motor housing.

[0018] 2. The dust is conducted to the lower cavity inside the negative pressure collection box through the common conduit in the inlet hole component and is intercepted and filtered by the filter. The filtered gas is transmitted from the output end of the vacuum pump to the nozzle component in the exhaust structure. The high-pressure airflow ejected by the nozzle component then sprays the metal debris generated by the motor housing during the grinding process into the inlet component, which helps to keep the machined surface of the motor housing clean and reduce the impact of the debris on its processing quality and efficiency.

[0019] 3. During the grinding process of the motor housing, when the filter screen in the lower chamber is clogged with debris and dust, the air pressure in the space on the leeward side of the filter screen in the lower chamber gradually decreases and drives the plug rod in the conical groove to move downward. The downward-moving plug rod drives the forced valve plate in the nozzle member to deflect downward from the initial horizontal state, so that the opening of the outlet end of the nozzle member decreases, and the air flow is more concentrated to spray toward the processing surface of the housing, thereby compensating for the spraying effect of the nozzle member, avoiding the blockage of the filter screen in the lower chamber of the collecting component, causing the loss of exhaust volume of the vacuum pump, and then causing the spraying effect of the nozzle member to decrease, thereby ensuring the removal effect of debris from the processing surface of the motor housing.

[0020] 4. When the filter screen in the lower chamber of the collecting component is clogged, causing the forced valve plate in the nozzle member to deflect downward, the ejector rod originally resting against the surface of the forced valve plate also moves downward under the elastic force of the sliding seat member. When the two switch terminals contact each other and trigger the solenoid valve in the inlet member to open, the top end of the ejector rod changes from a state extending from the end of the protective cylinder shell to a state flush with the end of the protective cylinder shell. When the operator finds whether the end of the ejector rod in the switch control extends from the end of the protective cylinder shell during the processing of the motor housing, he can quickly determine whether the filter screen in the collecting component is clogged, and can clean or replace it in time after the processing operation.

[0037] Reference Figures 7 to 11 , the embodiment of the present application provides an aluminum alloy motor housing processing device, the plug rod member includes an airtight piston 217 that slides in a sealed manner inside a cylindrical groove 220, a return spring 218 is connected to the bottom of the airtight piston 217, and one end of the return spring 218 away from the airtight piston 217 passes through a truncated cone groove 219 and is connected to the bottom wall of the lower chamber; The top of the cylindrical slot 220 is connected to an extension arm 213; When the return spring 218 is in the initial state, the airtight piston 217 is located inside the cylindrical groove 220 .

[0038] The metal dust generated during the grinding process on the surface of the aluminum alloy motor housing is continuously sucked into the interior of the inlet component under the suction of the vacuum pump 203, and the dust is conducted to the lower cavity through the common conduit 206 and is intercepted and filtered by the filter 216. The filtered gas is transmitted from the output end of the vacuum pump 203 to the nozzle member in the exhaust structure, and the high-pressure airflow ejected by the nozzle member sprays the metal debris generated during the grinding process of the motor housing into the inlet component, and the debris is further conducted to the lower chamber through the common conduit 206. When the filter 216 in the lower chamber is clogged with debris and dust, the air pressure in the space on the leeward side of the filter 216 in the lower chamber gradually decreases and The plug rod is driven to move downward, so that the airtight piston 217 moves from the inside of the cylindrical groove 220 to the inside of the truncated cone groove 219. When the downward-moving plug rod drives the forced valve plate 214 located in the nozzle member to deflect downward from the initial horizontal state, the ejector rod 212 originally resting on the surface of the forced valve plate 214 also moves downward under the elastic force of the sliding seat member. During the downward movement of the ejector rod 212, the two switch terminals 222 contact and trigger the solenoid valve 209 in the inlet component to open. After the airflow enters the upper cavity through the spare conduit 207, it flows through the lower cavity and flows back to the input end of the vacuum pump 203, thereby ensuring the effect of sucking away the metal powder generated during the cutting process of the motor housing.

[0040] The dust is conducted to the lower cavity inside the negative pressure collection box 201 through the common conduit 206 in the inlet hole component and is intercepted and filtered by the filter 216. The filtered gas is transmitted from the output end of the vacuum pump 203 to the nozzle component in the exhaust structure. The high-pressure airflow ejected by the nozzle component then sprays the metal debris generated by the grinding process of the motor casing into the inlet component, which helps to keep the machined surface of the motor casing clean and reduce the influence of the debris on its processing quality and efficiency.

[0041] During the grinding process of the motor housing, when the filter screen 216 located in the lower chamber is clogged with debris and dust, the air pressure in the space on the leeward side of the filter screen 216 in the lower chamber gradually decreases and drives the plug rod in the conical groove to move downward. The downward-moving plug rod drives the forced valve plate 214 located in the nozzle member to deflect downward from the initial horizontal state, so that the opening of the outlet end of the nozzle member decreases, and the air flow is more concentrated to spray toward the processing surface of the housing, thereby compensating for the spraying effect of the nozzle member, avoiding the blockage of the filter screen located in the lower chamber of the collecting component, causing the loss of exhaust volume of the vacuum pump 203, and then causing the spraying effect of the nozzle member to decrease, thereby ensuring the effect of removing debris from the processing surface of the motor housing.

[0043] When the filter in the lower chamber of the collecting component is clogged, causing the forced valve plate 214 in the nozzle member to deflect downward, the ejector rod 212 originally resting against the surface of the forced valve plate 214 also moves downward under the elastic force of the sliding seat member. When the two switch terminals 222 contact each other and trigger the electromagnetic valve 209 in the inlet component to open, the top of the ejector rod 212 changes from the state of extending from the end of the protective cylinder shell 211 to the state of being flush with the end of the protective cylinder shell 211, so that when the operator finds whether the end of the ejector rod 212 in the switch control extends from the end of the protective cylinder shell 211 during the processing of the motor housing, he can quickly determine whether the filter in the collecting component is clogged, and can clean or replace it in time after the processing operation.

The filtered gas is transmitted from the output end of the air pump 203 to the nozzle component in the exhaust structure; S3, the high pressure airflow ejected from the nozzle member ejects the metal debris generated during the grinding process of the motor housing into the inlet member, and the debris is then conducted into the lower chamber via the common conduit 206 in the inlet member; S4, when the filter screen 216 in the lower chamber is clogged by debris and dust, the air pressure in the space on the leeward side of the filter screen 216 in the lower chamber gradually decreases and drives the plug rod in the conical groove to move downward; S5, when the downwardly moving plug rod drives the forced valve plate 214 in the nozzle member to deflect downward from the initial horizontal state, the ejector rod 212 originally resting against the surface of the forced valve plate 214 also moves downward under the elastic force of the sliding seat member; S6, one of the switch terminals 222 moving with the slide member contacts the other switch terminal 222 located below it and triggers the solenoid valve 209 in the inlet member to open; S7. Under the negative pressure suction of the vacuum pump 203, metal dust and metal debris enter the upper chamber through the spare conduit 207, and are filtered by the filter screen 216 located in the upper chamber. The filtered gas is then ejected from the nozzle.
