For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] Referring to Figures 1-3 According to the embodiment of the chuck for straightening aluminum profile of the present application, two mounting plates 11 are distributed front and back, the two mounting plates 11 are connected by a back plate 12, and a clamping mechanism and an inner supporting mechanism acting on the aluminum profile are arranged between the mounting plates 11.

[0026] The clamping mechanism comprises an upper and lower distribution pressing plate 21 and a bottom plate 22, the bottom plate 22 is fixedly installed between the mounting plates 11, and further comprises a control assembly for controlling the movement of the pressing plate 21 to perform the clamping work of the aluminum profile. In this embodiment, the movement trajectory of the pressing plate 21 is designed as swing clamping, the left side of the pressing plate 21 is an arc surface, and the arc surface and the upper side of the bottom plate 22 are respectively provided with friction lines (not shown in the figure).

[0027] Specifically, the control assembly comprises a connecting plate 23 fixed to the mounting plate 11, a first hinge seat 24 is arranged on the connecting plate 23 and is distributed in front and back, a base 25 is hingedly connected in the first hinge seat 24, a second cylinder 26 is fixedly arranged on the base 25, the upper end of the pressing plate 21 is provided with a second hinge seat 27 which is distributed in front and back, the end of a second piston rod in the second cylinder 26 is hingedly connected between the second hinge seats 27, and the mounting plate 11 is rotationally connected with a hinge shaft, and the pressing plate 21 is fixed to the hinge shaft.

[0028] When the staff needs to clamp one end of the aluminum profile between the pressing plate 21 and the bottom plate 22, the staff controls the second piston rod in the second cylinder 26 to retract, so that the pressing plate 21 rotates clockwise by a certain angle with the axis of the hinge shaft as the center, so as to press the aluminum profile between the arc surface of the pressing plate 21 and the upper side of the bottom plate 22, and the same reason, when the second piston rod extends outward, the pressing plate 21 will rotate counterclockwise by a certain angle, so as to unlock the aluminum profile.

[0029] In addition, the inner supporting mechanism comprises a sliding plate 31 arranged between the mounting plates 11, a first cylinder 32 is arranged on the side of the sliding plate 31 away from the clamping mechanism, and a plug 33 is arranged at the end of a first piston rod in the first cylinder 32 penetrating through the sliding plate 31.

[0030] When the staff places the aluminum profile on the bottom plate 22 and the pressing plate 21 has not been pressed tightly, the first cylinder 32 can control the transverse movement of the plug 33 and make the plug 33 inserted into the aluminum profile, and then the pressing plate 21 can press the aluminum profile tightly, the function of the plug 33 is to avoid excessive deformation of the clamped aluminum profile and reduce the amount of waste material required for cutting after the aluminum profile is straightened.

[0031] After the steel pipe is straightened, the pressing plate 21 is unlocked and the plug 33 is retracted, because the clamping work of the pressing plate 21 and the bottom plate 22 on the aluminum profile will deform the aluminum profile and make it close to the plug 33, in order to avoid pulling the aluminum profile when the plug 33 is retracted and causing the plug 33 to fail to come out, the sliding plate 31 is further provided with an ejection assembly, the ejection assembly comprises an ejection plate 34 arranged on the sliding plate 31, the transverse width of the ejection plate 34 is not less than the transverse width of the plug 33, that is, the plug 33 can move to the right side of the left side of the ejection plate 34, when the plug 33 moves to the right, the ejection plate 34 remains relatively stationary and can abut against the end surface of the aluminum profile and avoid dragging the aluminum profile by the plug 33.

[0032] As Figure 3As shown, the top plate 34 is provided with two groups distributed on the upper and lower sides of the inner plug 33, so as to increase the contact area with the aluminum profile and avoid the occurrence of the skidding phenomenon.

[0033] In addition, since the aluminum profile has various specifications, the inner plug 33 can be disassembled and replaced with different styles and adapted to different specifications of the aluminum profile, and on this basis, the upper and lower positions of the top plate 34 are easily adjusted to be close to the upper and lower edges of the inner plug 33 after the style is replaced. Specifically, the left side of the sliding plate 31 is provided with two front and rear distributed first bosses 35, the top plate 34 is slidably connected to the sliding plate 31, and the bosses 35 are provided with a first bolt 36 for locking the upper and lower positions of the top plate 34. The staff can adjust the upper and lower positions of the top plate 34 by unscrewing the first bolt 36 and making it close to the inner plug 33.

[0034] In addition, in order to make the upper and lower positions of the inner plug 33 adjustable and adapted to different specifications of the aluminum profile, the sliding plate 31 is designed to be slidably connected between the mounting plates 11, and the mounting plates 11 are provided with a second bolt 13 for locking the upper and lower positions of the sliding plate 31. Similarly, the staff can adjust the upper and lower positions of the sliding plate 31 and the inner plug 33 by unscrewing the second bolt 13.

[0035] The nuts in the first bolt 36 and the second bolt 13 can be pressed against the wall surface to form a fixed.

[0036] It should be noted that the aluminum profile straightening chuck needs to be used in pairs and arranged oppositely. When the aluminum profile straightening work is performed, the two ends of the aluminum profile need to be clamped by the aluminum profile straightening chuck respectively, and then the aluminum profile straightening work can be performed by making the aluminum profile straightening chuck on one side move horizontally by a certain distance. The mounting plate 11 can also be provided with a pulley to facilitate the horizontal movement thereof, which is a conventional setting of the prior art and will not be described here.

[0037] In addition, before clamping, the staff needs to manually adjust the position of the aluminum profile and make it face the inner plug 33 in the front and rear directions. In order to make the inner plug 33 smoothly enter the aluminum profile, the left end surface of the inner plug 33 can be rounded or beveled.

[0038] The above only describes specific embodiments of the present application, but the technical features of the present application are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present application are covered by the patent scope of the present application.
