Description

Technical Field

[0001] The utility model belongs to the technical field of nonferrous metal processing. Background Art

[0002] At present, customers of 508 diameter aluminum tubes have very high requirements for the inner wall. The inner wall must be polished throughout the entire length, and no burrs, bumps, scratches, or other defects are allowed. Traditional manual polishing is inefficient and cannot work continuously. Workers need to drill into the aluminum tube and work with a handheld grinder. Operators are very likely to feel fatigued, which in turn affects the polishing effect. There are many cases of missed polishing. Because the internal space of the aluminum tube is very limited, it is very inconvenient for operators to enter and exit.

[0003] In summary, the problems existing in the prior art are:

[0004] (1) Traditional manual grinding is inefficient and cannot work continuously.

[0005] (2) Operators are very likely to feel fatigued, which in turn affects the grinding effect and often results in missed grinding.

[0006] (3) The internal space of the aluminum tube is very limited, making it very inconvenient for operators to enter and exit. Summary of the invention

[0007] The utility model aims to provide a wheel-type infrared master-controlled automatic grinding machine for the inner wall of an aluminum tube, which can realize automatic grinding of the inner wall of the aluminum tube.

[0008] The technical solution of the utility model is that it consists of a working end overall structure and a mobile end overall structure.

[0009] In the overall structure of the working end, several to dozens of steel pipes are arranged vertically in a circle, and the two ends of the steel pipes are welded and fixed by annular metal rings to form the main structure of the rolling cage-shaped working end. An array of support wheel slots are fixed between the steel pipe gaps of the main structure, and support wheels are installed in the support wheel slots. The outer edge of the support wheel extends to the outside of the main structure. The bottom support wheel cooperates with the motor transmission. An electric control operator, a controller box, a battery box and a motor box are respectively installed and fixed in the main structure. A coarse polishing grinding disc is installed at the front end of the main structure, and a round wheel scraper is fixed in front of the coarse polishing grinding disc.

[0025] Its structural principle is:

[0026] 1 Overall architecture of the work end

[0027] It is the main structure of the working end, which is composed of 10 steel pipes with a diameter of 50mm and a wall thickness of 5mm. Its two ends are fully welded on 5mm thick and 50mm wide circular steel plates, and its tail is fully welded on 5mm thick and 50mm wide circular steel plates. They form a whole. The wheel slot, battery box, controller box, operator, motor box, etc. need to be installed inside.

[0028] 2. Overall architecture of mobile terminal

[0029] It is the main structure of the mobile end, welded with 5mm thick steel plates, and is responsible for moving and loading the working end in and out of the aluminum tube. Four sets of universal wheels are installed at the bottom to achieve free movement and lift or lower to the height of the workbench interface. A revolving handrail is installed on the top for easy movement. The docking ports are installed at both ends, so that the mobile end can be tightly combined with the aluminum tube.

[0030] 3 Turnaround handrails

[0031] The revolving handrail is composed of two steel pipes with a diameter of 50mm and a wall thickness of 5mm. The two ends are bent 90 degrees and welded on the overall structure of the mobile end. It can be easily held, moved, and promoted.

[0032] 4 Universal wheels

[0033] Universal wheels are installed at the four corners of the bottom of the mobile end structure, with a total of four sets. With liftable universal wheels, we need to adjust the height before work so that the height of the docking interface is consistent with the height of the aluminum tube work surface, so as to facilitate the work end to enter and exit the aluminum tube.

[0034] 5 pairs of interfaces

[0035] The docking interface uses a 10mm thick 50mm steel plate bent into a semicircular structure. Its inner radius needs to be consistent with the outer wall radius of the aluminum tube to ensure that the docking interface and the aluminum tube can be tightly connected together, so that the working end can smoothly enter the aluminum tube. It is welded at both ends of the mobile end structure, regardless of the head or tail.

[0036] 6 round wheel scraper

[0037] It is made of 50mm×50mm square steel, bent into a ring structure, welded on the grinding disc, and its outer diameter is 2mm smaller than the inner diameter of the aluminum tube. The outer inner wall is polished into a sharp shape. During operation, it first impacts the larger burrs and protrusions on the inner wall of the aluminum tube, and blows out of the aluminum tube with the exhaust system. It can reduce the workload of the grinding disc, reduce the loss of the grinding disc, and increase the life of the grinding disc.

[0038] 7 Coarse polishing disc

[0039] The rough polishing disc consists of a motor, a rotating wheel, and sandpaper. The motor (500W three-phase brushless motor) is installed in the motor box of the working end structure, which provides the power for polishing. The rotating wheel is installed on the motor rotating rod, and there is an inclined connecting piece on the rotating wheel to connect the outer wheel, and the sandpaper is installed on the outer wheel. The inclined connecting piece can drive air flow when rotating, which can cool the motor and blow the small aluminum particles polished out of the aluminum tube.

[0040] 8 front infrared switch

[0041] The front infrared switch uses a trigger diffuse reflection infrared switch (adjusted to the normally closed mode, with a sensing range of 10cm), which directly controls the start and stop signals of the rough polishing disc. The rough polishing disc is started within the sensing area (entering the aluminum tube) and automatically shuts down after exceeding the sensing area (leaving the aluminum tube). The use of the front infrared switch can realize the automatic opening and closing function of the rough polishing disc.

[0042] 9 Operator

[0043] The operator is responsible for controlling all functions of stopping the movement of the working end. It is equipped with a manual operation switch, an automatic operation switch, a low battery warning light, a front infrared control switch, a rear infrared control switch, two front grinding disc control buttons, two rear grinding disc control buttons, and two power wheel buttons.

[0044] You can only turn on one of the manual and automatic operation switches, not both. The low battery warning light automatically triggers an alarm when the total battery power is less than 5%, reminding you that the battery is low and needs to be charged.

[0045] The operator and remote control are linked, and their functions are the same. Because the operator usually goes in and out of the aluminum tube with the working end and cannot be used directly, the remote control can be used to control the working end.

[0046] After starting the manual operation switch, the front grinding disc, rear grinding disc, power wheel forward and reverse rotation and operating speed can be directly controlled.

[0047] Before starting the automatic operation switch, you need to pre-adjust the forward and reverse rotation and running speed of the front grinding disc, rear grinding disc, and power wheel, start the front infrared control switch and the rear infrared control switch, and then dock the docking port of the mobile end with the aluminum tube. After starting the automatic operation switch, the grinding work can be automatically started. The front infrared control switch automatically senses and starts the coarse grinding disc motor, and the power wheel starts to move forward. After the rear infrared control switch enters the sensing area, the rear grinding disc motor starts to work. The front infrared control switch leaves the aluminum tube, and the coarse grinding disc motor is turned off after exceeding the sensing area. The rear infrared control switch leaves the aluminum tube, and the fine grinding disc motor is turned off after exceeding the sensing area. At the same time, the power wheel is turned off, and the grinding is automatically stopped. (The steering of the front and rear grinding discs needs to be opposite, and the working end runs stably).

[0048] 10 Support wheels

[0049] The support wheels are installed in the wheel slots of the working end overall structure, and are divided into 3 groups (15) of wheels in total. The bottom 3 wheels use electric motor wheels (36V electric skateboard wheels), and the remaining 12 wheels are unpowered wheels. These wheels allow the working end to move forward and backward.

[0050] 11 Rear infrared switch

[0051] The rear infrared switch uses a trigger diffuse reflection infrared switch (adjusted to the normally closed mode, with a sensing range of 10cm), which directly controls the start and stop signals of the fine polishing disc. The fine polishing disc is started within the sensing area (entering the aluminum tube) and automatically shuts down after exceeding the sensing area (leaving the aluminum tube). The use of the rear infrared switch can realize the automatic opening and closing function of the fine polishing disc.

[0052] 12 fine polishing discs

[0053] The fine polishing disc consists of a motor, a rotating wheel, and sandpaper. The motor (500W three-phase brushless motor) is installed in the motor box of the working end structure, which provides the power for grinding. The rotating wheel is installed on the motor rotating rod, and there is an inclined connecting piece on the rotating wheel to connect the outer wheel, and the sandpaper is installed on the outer wheel. The inclined connecting piece can drive air flow when rotating, which can cool the motor and blow the small aluminum particles that are polished out of the aluminum tube.
