[0025] The following describes the present application in detail with reference to the accompanying drawings and specific embodiments. Embodiment

[0026] As Figures 1 - 6 shown, an aluminum blank polishing device, a polishing table 1, two fixing plates 101 installed on the top of the polishing table 1, a left clamping cylinder 104 provided inside one of the fixing plates 101, a right clamping cylinder 105 provided inside the other fixing plate 101, a polishing assembly provided inside the polishing table 1, the polishing assembly includes: a rotating motor 106, a rotating hole 107, a chassis a108, a hanging bracket 112, a polishing motor 113 and a polishing grinding wheel 114, and a purification assembly provided on both outer ends of the polishing table 1, the purification assembly includes: a chassis b4, a high-pressure blower 401, a clean air box 402, a dust removal plate 404 and an activated carbon plate 405.

[0027] Among them, a left mounting head 102 connected to the left clamping cylinder 104 is provided inside one of the fixing plates 101, and the motor shaft of the rotating motor 106 passes through the rotating hole 107 and is connected to the left mounting head 102, and a right mounting head 103 connected to the right clamping cylinder 105 is provided inside the other fixing plate 101.

[0028] When polishing the aluminum tube blank, the right mounting head 103 is installed inside the fixing plate 101 through bolts, the right mounting head 103 and the right clamping cylinder 105 are rotationally connected through bearings, and for the rotating motor 106 at the outer end of the other fixing plate 101, the motor shaft of the rotating motor 106 passes through the rotating hole 107 and is connected to the left mounting head 102, and a threaded hole is provided at the bottom of the left mounting head 102, and a screw rod is threadedly connected inside the threaded hole. At this time, one end of the aluminum tube is inserted into the inside of the right clamping cylinder 105, and the other end of the aluminum tube is inserted into the inside of the left clamping cylinder 104. The inner diameter sizes of the left clamping cylinder 104 and the right clamping cylinder 105 are the same as those of the aluminum tube. Then, the screw rod is rotated and threadedly rotated inside the threaded hole, so that the screw rod passes through the threaded hole and presses against the aluminum tube inside the left clamping cylinder 104, thereby fixing the aluminum tube blank on the polishing table 1 for polishing treatment of the aluminum tube blank.

[0029] Its left mounting head 102, right mounting head 103 and polishing grinding wheel 114 are all flexibly detachable. When polishing aluminum tubes of different sizes, after disassembling them, just replace them with those that match the size of the aluminum tube. For the polishing grinding wheel 114, just replace it with one larger than the cross-section of the aluminum tube.

[0030] Among them, a support frame 2 is installed on the top of the polishing table 1. An activity groove 201 is opened at the top of the support frame 2, and the chassis a108 is located inside the activity groove 201. A limit plate 202 is installed on one side of the top end of the support frame 2. Push cylinders 203 are installed on both outer ends of the limit plate 202. One end of the push cylinder 203 is connected with a telescopic rod 204, and one end of the telescopic rod 204 is connected with the chassis a108. Sliding grooves 205 are respectively opened on both inner walls of the activity groove 201. Sliders 206 slidingly connected with the sliding grooves 205 are respectively installed on both outer ends of the chassis a108.

[0031] After fixing the aluminum tube blank on the polishing table 1, the aluminum tube and the polishing grinding wheel 114 are on the same horizontal line, and the size of the polishing grinding wheel 114 is larger than the cross-section of the aluminum tube. At this time, start the push cylinder 203 to drive the telescopic rod 204 to move. The telescopic rod 204 drives the chassis a108 to move inside the activity groove 201, that is, the hanging frame 112, polishing motor 113 and polishing grinding wheel 114 at the bottom of the chassis a108 move towards the aluminum tube, so that the polishing grinding wheel 114 can contact the aluminum tube and fit with the surface of the aluminum tube.

[0032] When pushing the chassis a108 to move back and forth inside the activity groove 201, since the chassis a108 is slidingly connected with the sliding grooves 205 on both inner walls of the activity groove 201 through the sliders 206 at both outer ends, it can ensure the stable operation of the chassis a108 inside the activity groove 201.

[0033] Among them, a rotary motor 106 is installed on the outer end of one of the fixing plates 101. A rotating hole 107 is opened on the outside of the fixing plate 101. A chassis a108 is arranged on the top of the polishing table 1. A hanging frame 112 is arranged at the bottom of the chassis a108. A polishing motor 113 is installed on one side of the outer end of the hanging frame 112. A polishing grinding wheel 114 is installed at the motor shaft end of the polishing motor 113. A stepping motor 109 is installed on one side of the outer end of the chassis a108. A reciprocating lead screw 110 connected with the stepping motor 109 is arranged inside the chassis a108, and the reciprocating lead screw 110 is rotatably connected with one end of the inner wall of the chassis a108 through a bearing. A thread sleeve 111 is arranged on the reciprocating lead screw 110. A threaded hole threadedly connected with the reciprocating lead screw 110 is opened inside the thread sleeve 111. A through groove is opened at the bottom of the chassis a108, and the hanging frame 112 passes through the through groove and is connected with the bottom of the thread sleeve 111.

[0034] After fixing the aluminum tube and pushing the polishing grinding wheel 114 to fit with its surface, start the polishing motor 113 to drive the motor shaft to drive the polishing grinding wheel 114 to rotate, so that the polishing grinding wheel 114 polishes the impurities on the surface of the aluminum tube clean. During the grinding process, start the rotating motor 106 and the stepping motor 109 to work. The rotating motor 106 drives the motor shaft to rotate in the rotating hole 107, and the motor shaft drives the left mounting head 102 and the left clamping cylinder 104 to rotate. The right mounting head 103 and the right clamping cylinder 105 are rotatably connected through bearings, so that the aluminum tube can be driven to rotate for peripheral grinding and polishing. Then, the stepping motor 109 drives the reciprocating lead screw 110 to rotate forward and backward. The lead screw sleeve 111 is threadedly rotated with the reciprocating lead screw 110 through the screw hole, so that the lead screw sleeve 111 can move back and forth on the reciprocating lead screw 110, and then the hanging bracket 112, the polishing motor 113 and the polishing grinding wheel 114 can be driven to move back and forth, so that the polishing grinding wheel 114 can polish different positions of the aluminum tube, which speeds up the polishing speed of the aluminum tube and can also solve the problem that the manual hand-held grinding and polishing is affected by vibration and is unstable, resulting in poor polishing quality.

[0035] Among them, a discharge groove 3 is opened at the bottom of the polishing table 1, and a collection box 301 aligned with the discharge groove 3 is provided at the bottom end inside the polishing table 1. When polishing the aluminum tube, the discharge groove 3 is located at the bottom of the aluminum tube, and the debris generated by grinding and polishing falls into the discharge groove 3 and is discharged into the collection box 301 through the discharge groove 3 for collection and storage, which is convenient for cleaning the debris.

[0036] Among them, machine boxes b4 are installed on both sides of the outer end of the polishing table 1, high-pressure blowers 401 are installed inside the machine boxes b4, air purification boxes 402 are installed on both sides inside the polishing table 1, a dust removal plate 404 is installed on one side inside the air purification box 402, an activated carbon plate 405 is installed on one side of the dust removal plate 404, an air extraction pipe is installed between the machine box b4 and the air purification box 402, an exhaust pipe 403 is installed on one side of the bottom of the high-pressure blower 401, and one end of the exhaust pipe 403 penetrates through the outside of the machine box b4. The inside of the dust removal plate 404 is dust-absorbing cotton, and the activated carbon plate 405 has a honeycomb structure.

[0037] When the air purification box 402 is installed on both sides inside the polishing table 1, one side of each of its two air purification boxes 402 is closely attached to the outer end of the discharge chute 3. When the cabinet door on the outside of the polishing table 1 is opened and the collection box 301 is placed inside the polishing table 1, the collection box 301 is snapped into the space between the two air purification boxes 402, so that the collection box 301 is just placed in alignment with the discharge chute 3. During the process of grinding and polishing the aluminum tube, dust and unpleasant fumes will be generated around the aluminum tube. At this time, start the high-pressure blower 401 to work. The high-pressure blower 401 generates negative pressure to suck air in the exhaust duct, so that the exhaust duct sucks air inside the air purification box 402 and the discharge chute 3, sucking the dust and unpleasant fumes generated around the aluminum tube into the discharge chute 3 for collection, and then into the air purification box 402. When passing through the dust removal plate 404, the dust-absorbing cotton inside can filter the dust in the air clean. After passing through the activated carbon plate 405 for the dust, the activated carbon plate 405 has a honeycomb structure and is composed of several honeycomb holes. Activated carbon particles are provided in each single honeycomb hole, and a breathable net is installed on the outside to prevent the activated carbon particles from falling out while ensuring that the air flow can pass through during air extraction. The unpleasant fumes can be adsorbed and purified by the activated carbon particles. After the dust and unpleasant fumes are treated, they are discharged from the exhaust pipe 403 to the outside of the machine case b4, avoiding the dust and unpleasant fumes from drifting into the working area and being directly inhaled by the workers, ensuring safe production and also avoiding harm to the health of the workers.

[0038] The cotton fibers of the dust-absorbing cotton are porous and contain many tiny voids, which allow air to pass through, thus improving the air permeability. The dust-absorbing cotton fibers can filter the dust in the air. After the dust is filtered, the air between the cotton fibers can still flow. Therefore, even after filtering the dust, the air permeability of the dust-absorbing cotton will not be significantly reduced. Coupled with the honeycomb structure of the activated carbon plate 405, it is conducive to air circulation to achieve the collection, filtration and purification of the dust and unpleasant fumes floating in the air.

[0039] Among them, a control chassis is fixedly installed on one side of the outer end of the support frame 2. A plurality of control buttons are installed on the top of the control chassis, and a power cord is installed on the back of the control chassis. The rotary motor 106, the stepping motor 109, the polishing motor 113, the pushing cylinder 203 and the high-pressure blower 401 are connected to the control chassis through wires, and the wires are reserved with sufficient length to ensure that they will not be pulled and broken during the back-and-forth pulling process. The length of the power cord is 3 meters, and a plug is installed at the other end of the power cord. The plug can be inserted into a socket in the room to connect to the power supply, so that the control chassis, the rotary motor 106, the stepping motor 109, the polishing motor 113, the pushing cylinder 203 and the high-pressure blower 401 are normally powered on and used. The rotary motor 106, the stepping motor 109, the polishing motor 113, the pushing cylinder 203 and the high-pressure blower 401 can be started and stopped through the control chassis. Moreover, for the control program involved in the present invention, those skilled in the art can all be realized according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0040] Among them, concave limiting blocks 406 for clamping the dust removal plate 404 and the activated carbon plate 405 are installed at the top and bottom inside the air purification box 402. A filter plate 407 is installed on the outside of the air purification box 402, and a partition net is installed on the outside of the filter plate 407. When the air purification box 402 sucks air into the discharge chute 3 to inhale dust and unpleasant smoke, the filter plate 407 and the partition net can isolate debris from being sucked into the inside of the air purification box 402, preventing the inside of the air purification box 402 from being blocked by accumulated debris. Moreover, the blocked debris just falls into the inside of the collection box 301. The settings of the filter plate 407 and the partition net can not only isolate debris, but also will not block the air purification box 402, ensuring the air circulation inside the air purification box 402, and then sucking air into the discharge chute 3 to inhale and collect the dust and unpleasant smoke generated around the aluminum pipe at the top of the discharge chute 3.

[0041] Working principle:

[0042] Insert one end of the aluminum pipe into the right clamping cylinder 105, and then insert the other end of the aluminum pipe into the left clamping cylinder 104. The inner diameter sizes of the left clamping cylinder 104 and the right clamping cylinder 105 are the same as those of the aluminum pipe. Then, the rotating screw thread rotates inside the screw hole, so that the screw penetrates the screw hole and presses against the aluminum pipe inside the left clamping cylinder 104, thereby fixing the aluminum pipe blank on the polishing table 1. The aluminum pipe and the polishing grinding wheel 114 are on the same horizontal line, and the size of the polishing grinding wheel 114 is larger than the cross-section of the aluminum pipe. At this time, start the pushing cylinder 203 to drive the telescopic rod 204 to move. The telescopic rod 204 drives the chassis a108 to move inside the movable groove 201, that is, the hanging frame 112, the polishing motor 113 and the polishing grinding wheel 114 at the bottom of the chassis a108 move towards the aluminum pipe, so that the polishing grinding wheel 114 can contact the aluminum pipe and fit with its surface.

[0043] After fixing the aluminum tube and pushing the polishing grinding wheel 114 to fit its surface, start the polishing motor 113 to drive the motor shaft to drive the polishing grinding wheel 114 to rotate, so that the polishing grinding wheel 114 polishes the impurities on the surface of the aluminum tube clean. During the grinding process, start the rotating motor 106 and the stepping motor 109 to work. The rotating motor 106 drives the motor shaft to rotate in the rotating hole 107, and the motor shaft drives the left mounting head 102 and the left clamping cylinder 104 to rotate. The right mounting head 103 and the right clamping cylinder 105 are rotationally connected through bearings, so that the aluminum tube can be driven to rotate and polished on its periphery. Then, the stepping motor 109 drives the reciprocating lead screw 110 to rotate forward and backward. The lead screw sleeve 111 rotates with the reciprocating lead screw 110 through the screw hole, so that the lead screw sleeve 111 can move back and forth on the reciprocating lead screw 110, and then can drive the hanging bracket 112, the polishing motor 113 and the polishing grinding wheel 114 to move back and forth, so that the polishing grinding wheel 114 can polish different positions of the aluminum tube, which speeds up the polishing speed of the aluminum tube and can also solve the problem that the manual hand-held polishing is affected by vibration and is unstable, resulting in poor polishing quality.

[0044] During the grinding and polishing process of the aluminum tube, dust and unpleasant fumes will be generated around the aluminum tube. At this time, start the high-pressure blower 401 to work. The high-pressure blower 401 generates negative pressure to suck air into the exhaust duct, so that the exhaust duct sucks air into the air purification box 402 and the discharge chute 3, and collects the dust and unpleasant fumes generated around the aluminum tube into the discharge chute 3, and then sucks them into the air purification box 402. When passing through the dust removal plate 404, the dust-absorbing cotton inside can filter the dust in the air clean. When passing through the activated carbon plate 405 after the dust, the activated carbon plate 405 is in a honeycomb structure and is composed of several honeycomb holes. Activated carbon particles are arranged in each single honeycomb hole, and a ventilation net is installed on the outside to prevent the activated carbon particles from falling out and ensure that the air flow can pass through during air extraction. The unpleasant fumes can be adsorbed and purified by the activated carbon particles. After the dust and unpleasant fumes are treated, they are discharged from the exhaust pipe 403 to the outside of the chassis b4, avoiding the dust and unpleasant fumes from drifting into the working area and being directly inhaled by the workers into the body, ensuring safe production and avoiding harming the health of the workers.
