[0019] The present invention is further described in detail below through specific embodiments.

[0020] like Figure 1 and Figure 2 As shown, a processing and fixing device for a channel steel 4 comprises a first support platform 1 and a second support platform 2, a processing support frame 3 for supporting the channel steel 4 is fixedly mounted on the first support platform 1, the processing support frame 3 is provided with a positioning structure for laterally positioning the channel steel 4, the second support platform 2 is mirror-set to the first support platform 1, the first support platform 1 and the second support platform 2 are both provided with a clamping mechanism for pressing the channel steel 4 onto the processing support frame 3, the clamping mechanism on the first support platform 1 comprises a mounting frame 5 arranged on the first support platform 1, the mounting frame 5 is provided with a moving block 6 for linear movement, the moving block 6 moves linearly toward the processing support frame 3, the moving block 6 is driven by a linear power device, and the moving block 6 is provided with a clamping structure for cooperating with the processing support frame 3 to position and fix the channel steel 4.

[0021] like Figure 2As shown, the clamping structure includes a pressing block 7 hinged in the middle on the moving block 6, the pressing block 7 is L-shaped, and is provided with a positioning portion 8 that is close to the positioning channel steel 4 and a clamping portion 9 that clamps the channel steel 4, and a tension spring 10 is provided between the positioning portion 8 and the moving block 6; the hinged pressing block 7 allows the pressing block 7 to rotate around the hinge point to improve the flexibility during clamping, and at the same time the tension spring 10 can deflect the clamping portion 9 upward, so that the positioning portion 8 can first contact the channel steel 4, and then cooperate with the positioning structure on the processing support frame 3 to fix the channel steel 4 on all sides and clamp it at the same time to ensure accurate fixation.

[0022] Furthermore, the positioning structure includes a processing raised rib 11 arranged on the processing support frame 3, and the processing raised rib 11 cooperates with the pressure block 7 to press tightly against the four sides of the channel steel 4. Since the cross-section of the channel steel 4 is a rectangular structure, the processing raised rib 11 and the processing support frame 3 can effectively support the bottom and one side of the channel steel 4. Then, when the pressure block 7 moves toward the processing support frame 3, the pressure block 7 can ensure that the positioning part 8 first approaches the other side of the channel steel 4, so that both sides of the channel steel 4 are supported, and then the clamping part 9 presses the top of the channel steel 4, effectively completing the positioning and fixing, and facilitating subsequent processing.

[0023] like Figure 2 As shown, a linear guide sleeve 12 is installed through the mounting frame 5, and a linear guide column 13 is installed inside the linear guide sleeve 12. The linear guide column 13 reciprocates along the linear guide sleeve 12 toward the processing support frame 3, and the linear guide column 13 is fixedly connected to the moving block 6; the cooperation between the linear guide column 13 and the linear guide sleeve 12 ensures that the pressing block 7 can move stably during the movement process, ensuring the accurate positioning and clamping of the channel steel 4.

[0024] The linear power device includes a compression and telescopic cylinder 14, which is fixedly mounted on the mounting frame 5, and the piston rod of the compression and telescopic cylinder 14 is connected to the moving block 6; the linear guide columns 13 are respectively mounted on both sides of the compression and telescopic cylinder 14, which can ensure accurate movement and improve the positioning and fixing effect.

[0025] The working principle of this embodiment is as follows: first, the channel steel 4 is placed on the processing support frame 3, and then the telescopic cylinder 14 is pressed to drive the pressure block 7 to move toward the processing support frame 3. When the positioning part 8 contacts one side of the channel steel 4, it will push the channel steel 4 to move until it rests against the processing raised rib 11, and the pressing part 9 will also press the upper surface of the channel steel 4.

[0026] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solution of the present invention, without departing from the design spirit of the present invention, should fall within the scope of protection defined in the claims of the present invention.
