Abstract

The invention discloses an automated grinding device for the production and processing of aluminum alloy pipes, and specifically relates to the technical field of aluminum alloy pipe production. The device comprises a front support platform, a rear support platform and a controller, wherein the rear support platform is fixed on the back of the front support platform, and high-pressure gas is passed through an air guide pipe, a connecting pipe and an air inlet pipe into a fixed cylinder, so that the fixed cylinder, a trapezoidal bracket and a top plate can be pushed as a whole toward the inner wall of the aluminum alloy pipe, thereby supporting the aluminum alloy pipe from the inside of the aluminum alloy pipe to prevent the aluminum alloy pipe from being deformed during subsequent grinding; a limiting ring is moved toward the middle of the support pipe, and the characteristic of the inclined hypotenuse of the trapezoidal bracket is utilized. When the limiting ring moves toward the middle of the support pipe, the length by which the trapezoidal bracket can be extended from the through hole becomes shorter, thereby preventing the trapezoidal bracket from extending too much to squeeze and deform the aluminum alloy pipe, and at the same time enabling the device to support aluminum alloy pipes with different inner diameters.

The air guide pipe 16 and the connecting pipe 29 are both hard pipes.

[0056] Furthermore, a safety mechanism is provided on the outside of the support tube 21 to prevent the trapezoidal support 14 from rising too high and causing deformation of the aluminum alloy tube;

[0057] The safety mechanism includes two limit rings 8, both of which are sleeved on the outside of the support tube 21, and the two limit rings 8 are respectively located on both sides of the through hole 31, and both sides of the limit rings 8 are connected with connecting arms 32, and a movable bolt 34 passes through the inside of the connecting arm 32, and a tooth plate 33 is fixed to the side of the movable bolt 34 facing the support tube 21, and a tooth groove 30 is opened on the outer wall of the support tube 21 on one side of the tooth plate 33, and a spring 35 is sleeved on the outside of the movable bolt 34 between the tooth plate 33 and the connecting arm 32.

[0058] Furthermore, a support plate 7 is arranged above the support block 6, and a second cylinder 23 for controlling the lifting of the support plate 7 is installed on the top of the support block 6. Guide pillars are penetrated on both sides of the support plate 7. The bottom of the guide pillars is fixed to the support block 6, and a limit plate 26 is fixed on the top of the guide pillars. The support plate 7 is located below the support tube 21. A groove 24 is opened on the top of the support plate 7, and a plurality of rollers 25 are installed in the groove 24. The number of rollers 25 is specified in the appendix of the manual. Figure 6 Three are shown in the figure, and you can add 25 rollers according to the actual situation.

[0059] Furthermore, a waste frame 1 is provided at the bottom of the front support platform 2 and the rear support platform 3, and a plurality of discharge holes are provided at the top of the front support platform 2. Figure 1-2 During the grinding process, the waste can be blocked by the shield 13 and then fall into the waste frame 1 through the discharge hole.

[0060] The specific working principle is as follows:

[0061] When in use, the aluminum alloy pipe is sleeved on the outside of the support pipe 21, and the top plate 12 is located inside the aluminum alloy pipe. Then, the air guide pipe 16 is connected to the air compressor inside the factory, so that the high-pressure gas enters the inside of the air guide pipe 16, and then the high-pressure gas will enter the connecting pipe 29 and the air inlet pipe 38 in sequence, and finally enter the inside of the fixed cylinder 36. With the injection of high-pressure gas, since the sealing ring 39 is fixed on the outside of the air inlet pipe 38, the fixed cylinder 36 will be forced to be pushed outward (the air hole 19 can be used to make the bottom of the fixed cylinder 36 connected and balanced with the external environment, ensuring that the fixed cylinder 36 can move normally, and the high-pressure gas The injection amount can be controlled by an air compressor in conjunction with a solenoid valve to prevent damage to the fixed cylinder 36, which is similar to the principle of a cylinder. This is a prior art and will not be described in detail), and then the trapezoidal bracket 14 and the top plate 12 are driven to move toward the inner wall of the aluminum alloy pipe as a whole, so as to support the aluminum alloy pipe from the inside of the aluminum alloy pipe to prevent the aluminum alloy pipe from deforming during the subsequent grinding process (some objects with relatively large friction, such as rubber pads, can be added to the top of the top plate 12, which can increase the friction of the top plate 12 on the aluminum alloy pipe and also prevent the inner wall of the aluminum alloy pipe from being damaged);

[0062] In order to prevent the trapezoidal bracket 14 and the top plate 12 from exerting too much pressure on the inner wall of the aluminum alloy pipe, the limiting ring 8 can be moved toward the middle of the support pipe 21. Since both sides of the trapezoidal bracket 14 are inclined upward, the closer the limiting ring 8 moves to the middle of the support pipe 21, the shorter the length that the trapezoidal bracket 14 can extend from the through hole 31. This method can protect the aluminum alloy pipe on the one hand, and on the other hand enable the device to support aluminum alloy pipes with different inner diameters.

[0063] During the movement of the limiting ring 8, the fixed movable bolt 34 needs to be pulled outward to separate the tooth plate 33 from the tooth groove 30. When the limiting ring 8 moves to the desired position, the movable bolt 34 is released. Under the action of the spring 35, the tooth plate 33 can be reset to make the tooth plate 33 mesh with the tooth groove 30 again to prevent the limiting ring 8 from loosening. (In order to clearly position the limiting ring 8 on the support tube 21, a length scale line can be engraved on the support tube 21. When engraving, the middle of the support tube 21 is taken as the 0 scale line, and then extended to both sides, that is, -3m, -2m, -1m, 0, 1m, 2m, 3m. In this way, the aluminum alloy pipe can also be aligned with the support tube 21 in the center. When aligning, for example, if the aluminum alloy pipe is 4m, the left end of the aluminum alloy pipe is located on the "-2m" scale, then the right side of the aluminum alloy pipe will be located on the "2m" scale.)

[0064] After the aluminum alloy pipe is pressed and supported, the second cylinder 23 can be used to drive the support plate 7 to move upward, so that the support plate 7 supports the support tube 21. The roller 25 can be used without affecting the subsequent rotation process of the support tube 21. Then, the first cylinder 11 pushes the cross plate 5, and then the vertical plate 4 and the support block 6 move toward the direction of the rear support platform 3, so that the aluminum alloy pipe outside the support tube 21 is in close contact with the grinding wheel 27. Then, the controller 15 controls the first motor 9 to control the rotation direction and number of rotations of the screw rod 40, so that the slide plate 20 moves along the rear support platform 3. At the same time, the second motor 10 drives the support tube 21 to rotate, and the third motor 17 drives the grinding wheel 27 to rotate. The three cooperate to grind the outer wall of the aluminum alloy pipe from left to right, thereby realizing the fully automatic grinding operation of the aluminum alloy pipe.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
