The adjusting device 2-18 is installed on the third mounting plate 2-10. The main function of the adjusting device 2-18 is to facilitate the adjustment of the distance between the upper and lower grinding wheels 2-19 after the grinding wheel 2-19 is worn, so as to ensure that the square tube frame is fully polished.

[0024] In use, since the device is connected to the previous process equipment, the square tube frame to be polished will be directly transferred to the polishing station after the previous process equipment is processed, realizing automatic loading. When the square tube frame is sent to the polishing station, the square tube frame polishing mechanism 1 is started.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, the third mounting seat 2-81 is mounted on the third mounting plate 2-10; the rotating handle 2-82 is mounted on the screw shaft 2-89; the second guide rail 2-83 is mounted on the third mounting seat 2-81; the second slider 2-84 is mounted on the second guide rail 2-83; the first mounting plate 2-85 is mounted on the second slider 2-84; the first mounting plate 2-85 is connected to the screw nut 2-92; the second mounting plate 2-86 is mounted on the first mounting plate 2-85; the first bearing mounting seat 2-87 and the second bearing mounting seat 2-90 are both mounted on the second mounting plate 2-86; the baffle 2-88 is mounted on the first bearing mounting seat 2-87 and the second bearing mounting seat 2-90; the screw shaft 2-89 is mounted on the third bearing mounting seat 2-91, and the screw shaft 2-89 is a positive and negative thread screw; the screw nut 2-92 is mounted on the screw shaft 2-89.

[0026] In use, when the rotating handle 2-82 is moved, the screw shaft 2-89 rotates with the rotating handle 2-82 to drive the screw nut 2-92 to move up and down. Since the screw shaft 2-89 is a positive and negative thread screw, when the screw shaft 2-89 rotates, the upper and lower screw nuts 2-92 will move in two different directions, thereby adjusting the distance between the upper and lower grinding wheels 2-19 to ensure that the square tube frame is fully polished.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, the mounting bracket 3-1 is mounted on the frame 1; the second cylinder 3-2 is mounted on the mounting bracket 3-1; the pressing block 3-3 is mounted on the second cylinder 3-2; the square tube frame is placed on the fixing seat 3-4; and the fixing seat 3-4 is mounted on the frame 1.

[0028] Before the square tube frame is polished, the second cylinder 3-2 is activated to drive the pressing block 3-3 to move downward to press the square tube frame; after the square tube frame is polished, the second cylinder 3-2 is activated to drive the pressing block 3-3 to move upward to release the square tube frame.

[0029] like Figure 1 and Figure 3 As shown, the rodless cylinder 4-1 is mounted on the fourth mounting seat 4-3; the pulling sheet metal 4-2 is mounted on the rodless cylinder 4-1; the fourth mounting seat 4-3 and the fifth mounting seat 4-4 are both mounted on the frame 1; the supporting rod 4-5 is mounted on the fifth mounting seat 4-4.

[0030] When the square tube frame is polished and the clamping mechanism 3 releases the square tube frame, the material return mechanism 4 is activated. The rodless cylinder 4-1 drives the material pulling sheet metal 4-2 to move rightward, and the material pulling sheet metal 4-2 drives the polished square tube frame to return rightward and fall on the supporting rod 4-5.

[0031] When in use, the clamping mechanism 3 starts to work first, and the second cylinder 3-2 works, driving the clamping block 3-3 to move downward to clamp the square tube frame. When the square tube frame is clamped, the motor 2-1 works, and drives the upper and lower grinding wheels 2-19 to rotate simultaneously through the V-belt 2-3, and the rotation directions are opposite. Among them: the grinding wheel 2-19 installed on the first transmission shaft 2-15 is directly driven to rotate by the V-belt 2-3; and the grinding wheel 2-19 installed on the transmission shaft 2-14 is driven by the first gear 2-6 and the second gear 2-7 to achieve rotation, and its rotation direction is opposite to that of the grinding wheel 2-19 on the second transmission shaft 2-15. The third transmission shaft 2-20 rotates driven by the V-belt 2-3. Since the second gear 2-7 is installed on the third transmission shaft 2-20, the second gear 2-7 also rotates together. The second gear 2-7 drives the first gear 2-6 to rotate together (the second gear 2-7 rotates in the opposite direction to the first gear 2-6). Since the first gear 2-6 is installed on the first transmission shaft 2-14, it drives the grinding wheel 2-19 on the first transmission shaft 2-14 to rotate together, and the rotation direction is opposite to the rotation direction of the grinding wheel 2-19 on the second transmission shaft 2-15. When the grinding wheel 2-19 is fully moved. The first cylinder 2-8 moves forward, driving the entire grinding mechanism 2 to move forward to grind the square tube frame. When the grinding is completed, the first cylinder 2-8 moves backward, driving the entire grinding mechanism 2 to move backward to leave the square tube frame. When the square tube frame is polished, the second cylinder 3-2 moves, driving the clamping block 3-3 to move upward to release the square tube frame. After the clamping mechanism 3 is completed, the material return mechanism 4 is activated. The rodless cylinder 4-1 drives the sheet metal 4-2 to move rightward, and the sheet metal 4-2 drives the polished square tube frame to move rightward, and finally the square tube frame falls on the supporting rod 4-5 to complete the material return. After the material return is completed, the rodless cylinder 4-1 moves, driving the sheet metal 4-2 to move leftward to the initial position, preparing for the next material return.

[0032] The entire equipment is controlled by PLC and sensors, and the control method of the entire equipment is simple and reliable; the square tube frame automatic grinding device can complete the grinding of four surfaces at one time, and all adopt automatic loading and unloading, which reduces the handling work of grinding, greatly reduces the labor intensity of employees and improves production efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
