Description

Technical Field

[0001] This utility model relates to the field of aluminum metal tube grinding technology, and in particular to an aluminum metal tube grinding device. Background Technology

[0002] Aluminum metal tubes are tubular materials manufactured from pure aluminum or aluminum alloys through extrusion molding. They possess the lightweight, corrosion resistance, and ease of processing inherent in aluminum, and are widely used in industry, construction, transportation, and electronics. When processing the surface of aluminum metal tubes, a grinding device is typically used to polish the surface, thereby improving the subsequent processing results and meeting the technical requirements of specific industries. When using a grinding device to polish aluminum metal tubes, the tube is placed on a guide rail between the grinding wheel and the guide wheel. Through the combined action of the grinding wheel and the guide wheel, the tube is automatically fed into the grinding area for polishing.

[0003] When grinding aluminum metal pipes, debris is generated. Currently, the existing technology usually uses an exhaust fan to absorb and collect the generated debris. However, due to the static electricity generated by the grinding wheel during the grinding process, some debris will still adhere to the surface of the grinding wheel and guide wheel and cannot be absorbed. This can easily lead to scratches on the surface of the aluminum metal pipes when the grinding wheel grinds them, affecting the grinding quality of the aluminum metal pipes. Utility Model Content

[0004] Therefore, it is necessary to provide an aluminum tube grinding device to address the problem that some debris adheres to the surface of the grinding wheel and guide wheel and cannot be adsorbed, which easily leads to scratches on the surface of the aluminum tube when the grinding wheel grinds the aluminum tube, thus affecting the grinding quality of the aluminum tube.

[0005] The device includes: an operating table with a grinding mechanism mounted on its top; a cleaning mechanism comprising a collection box fixedly connected to one side of the operating table, a fan mounted on one side of the collection box, two fixed frames fixedly connected to the top of the operating table, a T-shaped pipe connected to the top of the collection box, the other two ends of the T-shaped pipe being connected to the bottom ends of the two fixed frames respectively, a brush roller rotatably connected to the upper end of the inner wall of the fixed frame, a round rod slidably connected to the inner wall of the fixed frame, a plurality of evenly distributed paddles fixedly connected to the upper end of the surface of the round rod, and a drive assembly provided on one side of the fixed frame.

[0006] In one embodiment, the cleaning mechanism further includes a filter plate fixedly connected to the inner wall of the collection box, the two sides of the filter plate being inclined. This facilitates the interception of adsorbed debris, ensuring the normal operation of the fan, and the inclined surface of the filter plate helps the collected debris slide down to the lower part of the filter plate, ensuring the ventilation effect of the filter plate.

[0007] In one embodiment, the driving assembly includes a first motor fixedly connected to one side of the fixed frame. One end of the brush roller passes through the fixed frame and is fixedly connected to the output shaft of the first motor. The other end of the brush roller passes through the fixed frame and is fixedly connected to a reciprocating screw. A slide rod is mounted on the surface of the reciprocating screw, and the bottom end of the slide rod is fixedly connected to the surface of the round rod. This facilitates driving the round rod to move multiple levers reciprocally in the horizontal direction.

[0008] In one embodiment, a collection plate is embedded in the middle of the inner wall of the filter plate, and the collection plate is parallel to the horizontal plane. This facilitates better collection of debris and makes it easier to clean the collected debris later.

[0009] In one embodiment, the vertical cross-section of the prying block is an isosceles triangle, and multiple prying blocks are located on the same axis. This helps to ensure the prying effect of the prying block on the bristles while reducing the friction between the prying block and the bristles.

[0010] In one embodiment, a fixing plate is fixedly connected to the side of the fixing frame away from the first motor, and protective sleeves are fixedly connected to both sides of the slide rod. The other ends of the two protective sleeves are respectively fixedly connected to the surface of the fixing plate and the surface of the fixing frame. The reciprocating screw is located inside the protective sleeve. This facilitates the protection of the reciprocating screw and ensures the stability of the connection between the slide rod and the reciprocating screw during the operation of the device.

[0011] In one embodiment, the upper and lower ends of the surface of the fixing frame both form an angle with the vertical plane. This facilitates better entry of debris into the fixing frame when it sucks in debris, and the shape of the bottom end of the fixing frame further facilitates better entry of debris into the tee pipe.

[0012] Beneficial effects

[0013] 1. When polishing aluminum tubes, two rotating brush rollers effectively remove debris adhering to the surfaces of the polishing wheel and guide wheel, detaching the debris from these surfaces. A negative pressure is created in the collection box by activating a fan, which helps the two fixed frames attract and collect the debris, ensuring effective collection. Simultaneously, as the brush rollers rotate and contact the paddles, the reciprocating movement of the paddles bends and deforms the bristles, detaching them from the bristles and allowing them to be drawn into the collection box by the airflow. This prevents debris from remaining on the bristles, keeping the brush rollers clean throughout the process. This ensures effective cleaning of the polishing wheel and guide wheel surfaces, thus guaranteeing a successful polishing of the aluminum tube.

[0014] 2. The filter plate is designed to intercept adsorbed debris, ensuring the normal operation of the fan. The inclined surface of the filter plate also helps the debris collected by the filter plate to slide down to the lower part of the filter plate, ensuring the ventilation effect of the filter plate.

[0028] The following is combined with Figures 1-5 This invention describes an aluminum metal tube grinding device.

[0029] In one embodiment, an aluminum metal tube polishing device includes: an operating table 100, with a polishing mechanism 200 mounted on the top of the operating table 100; a cleaning mechanism 300, which includes a collection box 310 fixedly connected to one side of the operating table 100, a fan 320 mounted on one side of the collection box 310, two fixed frames 330 fixedly connected to the top of the operating table 100, a three-way pipe 311 connected to the top of the collection box 310, the other two ends of the three-way pipe 311 respectively connected to the bottom ends of the two fixed frames 330, a brush roller 340 rotatably connected to the upper end of the inner wall of the fixed frame 330, a round rod 350 slidably connected to the inner wall of the fixed frame 330, a plurality of evenly distributed pry blocks 351 fixedly connected to the upper end of the surface of the round rod 350, and a drive assembly 360 provided on one side of the fixed frame 330.

[0030] It should be noted that the grinding mechanism 200 includes two drive motors, a reducer, a grinding wheel, a guide wheel, and a workpiece guide rail. The guide wheel and the grinding wheel are located on the same vertical plane. One end of the grinding wheel is fixedly connected to the output shaft of one of the drive motors, and one end of the guide wheel is installed with the reducer. The other drive motor is started by the controller, and the power is transmitted to the guide wheel through the reducer, causing the guide wheel to rotate. The workpiece guide rail is located between the grinding wheel and the guide wheel. When grinding the pipe using the grinding mechanism 200, the pipe is placed on the workpiece guide rail, and one end of the pipe is inserted between the grinding wheel and the guide wheel. The two drive motors are started by the controller, thereby transmitting power to the grinding wheel and the guide wheel, causing the grinding wheel and the guide wheel to rotate at a certain speed. The guide wheel plays the role of guiding and fixing the pipe, ensuring that the pipe maintains stable linear motion during the grinding process. Under the combined action of the grinding wheel and the guide wheel, the pipe is automatically fed into the polishing area, and the grinding wheel and the surface of the pipe generate strong friction to perform the grinding operation.

[0031] The operating principle of the grinding mechanism 200 is existing known technology and is a known grinding device. The technical solution of this application is aimed at the problem of cleaning grinding debris. Therefore, the internal structure of the grinding mechanism 200 is not labeled and described in detail. The grinding mechanism 200 is drawn with reference to existing aluminum metal pipe grinding equipment.

[0032] In this embodiment, two fixed frames 330 are respectively disposed below the grinding wheel and the guide wheel in the grinding mechanism 200. The bristles of the two brush rollers 340 are in contact with the lower end of the surface of the grinding wheel and the lower end of the surface of the guide wheel, respectively. The bristles of the brush rollers 340 are soft bristles that can be deformed.

[0033] like Figure 2 As shown, the cleaning mechanism 300 also includes a filter plate 312 fixedly connected to the inner wall of the collection box 310, and the two sides of the surface of the filter plate 312 are inclined.

[0034] In this embodiment, the connection between the blower 320 and the collection box 310 is located below the filter plate 312. The collection box 310 has an opening on the side away from the operating table 100, and the opening is fitted with a cover plate. During use, the cover plate seals the opening and is installed with the collection box 310 by bolts. When cleaning the debris on the filter plate 312, the cover plate can be opened to clean the debris on the filter plate 312.

[0035] like Figure 2 and Figure 4 As shown, the drive assembly 360 includes a first motor 361 fixedly connected to one side of the fixed frame 330. One end of the brush roller 340 passes through the fixed frame 330 and is fixedly connected to the output shaft of the first motor 361. The other end of the brush roller 340 passes through the fixed frame 330 and is fixedly connected to a reciprocating screw 362. A slide bar 363 is mounted on the surface of the reciprocating screw 362. The bottom end of the slide bar 363 is fixedly connected to the surface of the round rod 350.

[0036] In this embodiment, when the first motor 361 is started by the controller, the output shaft of the first motor 361 will drive the brush roller 340 to rotate synchronously, thereby driving the reciprocating screw 362 to rotate synchronously, driving the slide bar 363 to drive the round rod 350 to reciprocate in the horizontal direction, thereby causing the round rod 350 to drive multiple paddles 351 to reciprocate in the horizontal direction. The distance of the paddles 351 reciprocating in the horizontal direction is short, and the brush bristles of the brush roller 340 will not bend significantly during the reciprocating movement of the paddles 351. The surface of the round rod 350 is slidably connected to the inner wall of the fixed frame 330.

[0037] like Figure 2 As shown, a collection plate 313 is embedded in the middle of the inner wall of the filter plate 312, and the collection plate 313 is parallel to the horizontal plane.

[0038] In this embodiment, one end of the three-way pipe 311 is located above the collecting plate 313, and the collecting plate 313 is located in the recess of the filter plate 312. When the debris enters the collecting box 310 through the three-way pipe 311, some of the debris will fall onto the collecting plate 313 under its own gravity. When the fan 320 stops running, the debris on the surface of the filter plate 312 will slide onto the collecting plate 313 under the action of the inclined surface of the filter plate 312. The debris on the collecting plate 313 can be cleaned by opening the cover.

[0039] like Figure 4 and Figure 5 As shown, the vertical cross-section of the lever 351 is an isosceles triangle, and multiple levers 351 are located on the same axis.

[0040] In this embodiment, the rotation path of the end of the brush bristles away from the roller shaft of the brush roller 340 coincides with that of the paddle block 351. Therefore, during the rotation of the brush roller 340, multiple paddle blocks 351 will contact the end of the brush bristles away from the roller shaft.

[0041] like Figure 4 As shown, a fixing plate 364 is fixedly connected to the side of the fixing frame 330 away from the first motor 361, and protective sleeves 365 are fixedly connected to both sides of the slide rod 363. The other ends of the two protective sleeves 365 are fixedly connected to the surface of the fixing plate 364 and the surface of the fixing frame 330, respectively. The reciprocating screw 362 is set inside the protective sleeves 365.

[0042] In this embodiment, the protective sleeve 365 is a rubber component. When the slide bar 363 moves, it can drive the corresponding protective sleeve 365 to extend and retract. The protective sleeve 365 protects the surface of the reciprocating lead screw 362.

[0043] like Figure 3 As shown, the upper and lower ends of the surface of the fixed frame 330 form an angle with the vertical plane.

[0044] In this embodiment, the top opening of the fixing frame 330 is larger than the middle width of the fixing frame 330, and the bottom opening of the fixing frame 330 is smaller than the middle width of the fixing frame 330.

[0045] Working principle: When grinding aluminum tubes, the aluminum tube is placed on the workpiece guide rail in the grinding mechanism 200, and the grinding mechanism 200 is driven to grind the aluminum tube. Simultaneously, the cleaning mechanism 300 operates synchronously. During the rotation of the grinding wheel and guide wheel in the grinding mechanism 200, the controller starts two first motors 361, driving the corresponding brush rollers 340 to rotate. The two brush rollers 340 clean the debris adhering to the surfaces of the grinding wheel and guide wheel, causing the debris to detach from them. The controller then starts the fan 320, which discharges air from the collection box 310, allowing the other two ends of the three-way pipe 311 and the corresponding fixed frame 330 to draw in external air. The debris from the detached grinding wheel and guide wheel is drawn into the fixed frame 330, the three-way pipe 311, and the collection box 310 by the wind. As the brush roller 340 rotates, it drives the reciprocating screw 362 to rotate synchronously. This drives the round rod 350 via the slide rod 363 to move multiple paddles 351 reciprocally in the horizontal direction. When the bristles of the brush roller 340 overlap with the paddles 351 during the cleaning rotation, the reciprocating movement of the paddles 351 moves the bristles, causing them to bend and deform. This causes the debris attached to the bristles to detach and be adsorbed into the collection box 310 by the wind. After the aluminum metal tube is polished, the polishing mechanism 200 and the cleaning mechanism 300 can be closed.

[0046] Note: The reciprocating screw 362 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 362 causes the side of the helical groove to push the slider placed in the helical groove to make axial reciprocating motion. Therefore, when the reciprocating screw 362 is driven to rotate, it will drive the slide rod 363 to move reciprocally in the horizontal direction.

[0047] It should be noted that the fan 320 and the first motor 361 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the power supply of the fan 320 and the first motor 361 can be powered by the built-in power supply or by the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
