Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, and more specifically, to a device for blowing and brushing floating powder on the surface of a spiral bevel gear. Background Art

[0002] Spiral bevel gears are a type of mechanical component commonly used to transmit large torque and high speed. They are widely used in machine tools, automobiles, metallurgy and other industries. Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. It can be used to prepare spiral bevel gears. However, during the production process of spiral bevel gears, a layer of floating powder will always adhere to the entire surface. Sintering it directly will seriously affect the product quality. Therefore, the floating powder needs to be removed after pressing and forming. However, it is not advisable to use a special process to remove the floating powder, as it takes too much time. The longer the time, the less likely the floating powder will fall off, which will cause surface quality defects. It is usually necessary to complete the floating powder blowing and brushing work during the automatic transportation process after pressing and forming. However, due to the tight process time, the floating powder blowing and brushing often leads to incomplete coverage, which will create dead corners and affect product quality.

[0003] After searching, the Chinese patent with publication number CN116000288A discloses a powder metallurgy part surface floating powder blowing and brushing device. The structure sets a part grabbing and flipping mechanism, which faces the parts with toothed structures on the surface to prevent them from falling during the transmission process and the surface teeth from breaking, thereby ensuring the product processing quality. At the same time, the part grabbing and flipping mechanism can shake off the floating powder on the flat side of the parts during the flipping of the pressed parts, without generating dead angles that affect the product quality.

[0004] However, when this structure is actually used, the gripper will contact the part when the gripping mechanism clamps the part, so that the floating powder on the surface of the part will be embedded in the surface of the part at the contact point between the gripper and the part, thereby causing surface defects of the part. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a device for blowing and brushing floating powder on the surface of spiral bevel gears to solve the problems raised in the above background technology.

[0007] Preferably, the vacuum cleaning assembly includes a mounting bracket, which is arranged on the top of the conveying workbench, a connecting plate is provided on one side of the mounting bracket, a connecting port is provided inside the mounting bracket, a cleaning brush is provided inside the connecting port, a mounting groove is provided on the top surface of the mounting bracket, a transverse rotating fan is provided inside the mounting groove, a placement groove is provided on the surface of the mounting bracket, a driving motor is provided inside the placement groove, a slide groove is provided on the top surface of the mounting bracket, a sealing cover is provided on the top of the mounting bracket, the bottom of the sealing cover is slidably connected to the slide groove, a dust box is provided on the top of the mounting bracket, a rotating fan is provided on one side of the dust box, a filter plate is provided inside the dust box, a fixed clamping pipe is provided on one side of the dust box, and a connecting pipe is provided on one side of the sealing cover.

[0008] Through the above scheme, it can be seen that the mounting frame is set on the top of the conveying workbench, and the pressing machine is connected to the conveyor belt through the connecting port. Then, after the gear is pressed and formed, after entering the inside of the mounting frame, the cleaning brush will clean the floating powder on the surface of the gear, and the cleaned floating powder will float in the air. At this time, the driving motor is started, and the driving motor is used to drive the transverse rotating fan to rotate, and then the transverse rotating fan will drain the floating powder inside the connecting port to the inside of the sealing cover. Then the rotating fan is started, and the fixed clamping tube is clamped with the connecting pipe to absorb the floating powder inside the sealing cover into the inside of the dust box, and under the action of the filter plate, it will not be discharged from the dust box. At this time, the floating powder on the surface of the gear will be cleaned, and it will not affect the surrounding environment, thereby improving the practicality of the device.

[0009] Preferably, a fan is installed on the top of the floating powder blowing box, and the number of the fans is set to two. An inclined panel is provided on one side of the conveying workbench, and one end of the inclined panel is located directly above the parts concentration turntable. A servo motor is provided on the top of the mounting frame, and the output end of the servo motor is coaxially connected to one end of the cleaning brush, and the output end of the drive motor is coaxially connected to one end of the transversely rotating fan, and one end of the transversely rotating fan is movably connected to the inner wall of the mounting groove, and the connecting pipe is detachably connected to the fixed clamping pipe, and the connecting pipe runs through the dust collecting box and communicates with the inside of the dust collecting box.

[0010] Through the above scheme, it can be seen that a fan is arranged on the top of the floating powder blowing box, and then the fan is used to blow air on the gear surface to blow away the floating powder on the gear surface. Because the gear has been cleaned, when the fan blows air on the gear, less floating powder will be emitted from the gear surface, which will not affect the air quality. The secondary cleaning can further improve the cleanliness of the gear and improve the cleaning efficiency.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a dust suction cleaning component, compared with the prior art, the mounting frame is set on the top of the conveying workbench, and the pressing machine is connected to the conveyor belt through the connecting port.

At this time, the driving motor is started, and the driving motor is used to drive the horizontal rotating fan to rotate, and then the horizontal rotating fan will drain the floating powder inside the connecting port to the inside of the sealing cover, and then the rotating fan is started, and the fixed clamping pipe is clamped with the connecting pipe to absorb the floating powder inside the sealing cover into the inside of the dust collecting box, and the dust collecting box is not discharged under the action of the filter plate. At this time, the floating powder on the surface of the gear will be cleaned, and it will not affect the surrounding environment, thereby improving the practicality of the device;

[0013] 2. By setting up a fan, a fan is set on the top of the floating powder blowing box, and then the fan is used to blow air on the surface of the gear to blow away the floating powder on the surface of the gear. Because the gear has been cleaned, when the fan blows air on the gear, less floating powder will be emitted from the surface of the gear, which will not affect the air quality. The secondary cleaning can further improve the cleanliness of the gear and improve the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
