The pressure block is an integrated structure, and includes three parts: a horizontal plate, a left inclined plate and a right inclined plate. The outer sides of the left inclined plate and the right inclined plate are both provided with a trapezoidal guide rail that cooperates with the dovetail groove on the same side. The left inclined plate is in sliding contact with the inner side of the left inclined plate, and the right inclined plate is in sliding contact with the inner side of the right inclined plate. There is an aluminum profile between the left wedge block and the right wedge block. Elastic parts for resetting are connected to one corner of the left wedge block and the right wedge block.
[0006] Further, the elastic member is a tension spring. A row of horizontal tension springs are connected to the lower left corner of the left wedge block and the lower right corner of the right wedge block, and the other end of the tension spring is connected to the inner wall of the base.
[0007] Furthermore, vertical air outlet holes are provided on the horizontal plate.
[0008] Furthermore, a limit block is provided at the upper end of the cavity.
[0009] Furthermore, the upper end surface of the pressing block is connected with a cylinder.

[0011] The utility model also includes other components that enable the aluminum profile stretching processing clamping fixture to be used normally, and these devices or components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the stretching spring, cylinder, etc. in this application. In the specific implementation process, the appropriate equipment or component model can be selected according to the specific working scene.
[0012] The working principle of the utility model is as follows: when clamping an I-shaped aluminum profile, the cylinder pushes the pressing block to move down along the dovetail groove, and the left and right inclined plates of the pressing block respectively push the left and right wedge blocks to clamp the aluminum profile, and the tension springs on both sides are stretched, while the horizontal plate of the pressing block clamps the aluminum profile from above. After the aluminum profile is clamped, the cylinder drives the pressing block to move up, and the tension spring is shortened, so that the left and right wedge blocks are reset. The rubber pads set in multiple places can protect the aluminum profile and avoid direct extrusion.

The outer sides of the left inclined plate 22 and the right inclined plate 23 are both provided with a trapezoidal guide rail 24 that cooperates with the dovetail groove 11 on the same side. The left wedge block 3 is in sliding contact with the inner side of the left inclined plate 22, and the right wedge block 4 is in sliding contact with the inner side of the right inclined plate 23. The aluminum profile 7 is between the left wedge block 3 and the right wedge block 4. Elastic parts for resetting are connected to one corner of the left wedge block 3 and the right wedge block 4.
