DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 5 The illustrated fixture for processing aluminum profiles includes a support plate 1, which is provided in two pieces. The top of the support plate 1 is rotatably connected with a rotating shaft 2, and there is a certain damping sense between the rotating shaft 2 and the support plate 1. When pushed by an external force, the rotating shaft 2 can rotate, and after the external force stops, the rotating shaft 2 can maintain a positioning state to avoid arbitrary rotation, which is convenient for clamping the aluminum profile body 21. The ends of the two rotating shafts 2 close to each other are fixedly connected with a square plate 19. A vertical box 3 is fixedly connected to the side wall of the square plate 19, and a sliding box 4 is slidably provided on the top of the vertical box 3. The sliding box 4 is connected to the vertical box 3. A clamping plate 5 is provided above the square plate 19, and the clamping plate 5 is fixedly connected to the sliding box 4. An electric push rod 6 is fixedly connected between the vertical box 3 and the sliding box 4.

[0024] During operation, the electric push rod 6 can control the up and down movement of the clamping plate 5 through the sliding box 4 .

[0025] Considering the unevenness of the surface of the aluminum profile body 21 (refer to Figure 5 ), a first air groove 8 is provided inside the clamping plate 5, and an airbag 7 is fixedly connected to the lower surface of the clamping plate 5. When in use, the flat side of the aluminum profile body 21 is placed on the square plate 19. When the airbag 7 is inflated, it will adaptively abut against the unevenness of the aluminum profile body 21 to improve the positioning stability; at the same time, the airbag 7 also has a certain buffering effect to prevent the aluminum profile body 21 from deforming.

[0026] The airbag 7 is connected to the slide box 4 through the first air groove 8. The top of the square plate 19 is provided with an annular groove 10, which surrounds the outer side of the rotating shaft 2. The vertical box 3 is connected to the annular groove 10 through the gas channel 9. The support plate 1 is provided with a second air groove 11 for conveying gas, and the second air groove 11 is connected to the annular groove 10. The annular groove 10 is provided so that the gas channel 9 can always be connected to the annular groove 10 even if the rotating shaft 2 rotates.

[0027] A square tube 12 is fixedly connected between the two support plates 1, and the two second air grooves 11 are connected through the square tube 12. At the same time, the square tube 12 can also improve the stability of the overall structure.

[0028] A pump body 13 is fixedly connected to one of the support plates 1 . The pump body 13 is communicated with the corresponding second air groove 11 , and the pump body 13 can be switched between air supply and suction.

[0029] A solenoid valve 20 is fixedly installed inside the sliding box 4 .

[0030] During operation, the end of the aluminum profile body 21 is placed between the airbag 7 and the square plate 19, and the telescopic end of the electric push rod 6 is controlled to be retracted, driving the clamping plate 5 and the airbag 7 to move toward the square plate 19. When the airbag 7 abuts against the aluminum profile body 21, the electric push rod 6 stops running; the pump body 13 is started to control its air supply operation. The pump body 13 transports gas to the inside of the airbag 7 through the second air groove 11, the annular groove 10 and other structures. After the airbag 7 is inflated, it will adaptively abut against the unevenness of the aluminum profile body 21, and then the solenoid valve 20 is closed, thereby completing the clamping positioning and improving the processing quality.

[0031] When the aluminum profile body 21 needs to be taken out, the solenoid valve 20 is opened to control the pump body 13 to perform a suction operation.

[0032] It should be noted that a pressure sensor may be provided inside the first air groove 8 to monitor the expansion and extrusion force of the airbag 7 to prevent the airbag 7 from over-expanding and extruding the aluminum profile body 21 to deform. The pressure sensor is a common existing technology and will not be described in detail here.

[0033] The aluminum profile body 21 is clamped only at two ends, so that the middle section of the aluminum profile body 21 can be processed easily.

[0034] In addition, since the rotating shaft 2 is rotatably arranged on the top of the supporting plate 1, after the aluminum profile body 21 is clamped and positioned, it can also be angularly deflected, which is convenient for processing multiple surfaces.

[0035] When the aluminum profile body 21 is clamped between the clamping plates 5 and the square plate 19 on both sides, the clamping plates 5 and the square plate 19 on both sides can be made to rotate synchronously.

[0036] In order to achieve the positioning of the rotating shaft 2, a block 14 is fixedly connected to the rotating shaft 2, and the block 14 is located on the side of the support plate 1 facing away from the vertical box 3. A sliding rod 15 is slidably connected to the block 14, and a circular plate 17 is fixedly connected to the end of the sliding rod 15 away from the support plate 1. A spring 16 is mounted on the sliding rod 15, and one end of the spring 16 is fixedly connected to the circular plate 17, and the other end of the spring 16 is fixedly connected to the block 14. A circular groove 18 is opened on the support plate 1, and a plurality of circular grooves 18 are arranged, and the plurality of circular grooves 18 are evenly distributed around the rotating shaft 2, and the circular grooves 18 cooperate with the sliding rod 15.

[0037] During operation, the circular plate 17 is pulled away from the support plate 1, so that the slide rod 15 is pulled out from the inside of the circular groove 18, and then the rotating shaft 2 is rotated to deflect the angle of the aluminum profile body 21, which is convenient for processing multiple surfaces; after the adjustment is completed, the slide rod 15 is inserted into the corresponding circular groove 18 to complete the positioning of the rotating shaft 2.
