During processing, these windows and doors must be clamped onto a workbench before being processed. However, existing clamping devices are not adaptable to doors and windows of varying sizes, and can cause them to wobble during processing. For example, announcement number CN221048353U discloses a door and window processing and clamping device, comprising a workbench and a movable block, the movable block being located at the four corners of the inner cavity of the workbench, a first through-hole being formed on the lower side of the inner side wall of the movable block, the first through-hole penetrating the movable block and extending to the outer side wall of the movable block, a first slide bar being inserted between the inner cavities of the first through-hole on the left and the first through-hole on the right, a second through-hole being formed on the upper side of the inner side wall of the movable block, the second through-hole penetrating the movable block and extending to the outer side wall of the movable block, a second slide bar being inserted between the inner cavities of the second through-hole on the front and the second through-hole on the rear.

[0033] The operating process of the door and window processing and clamping device of the present invention is as follows: the door and window body to be processed is placed on the workbench 1, and the two vertical side surfaces of one corner of the door and window body are aligned with the inner side surfaces of the clamping plate 6 of the first positioning block 2. The first operating cylinder 802 is activated. The first connecting block 801 is fixed to the front end of the first operating cylinder 802. The first sliding rod 13 passes through the two ends of the first connecting block 801 and is respectively connected to the first sliding block 10 and the second sliding block 11.

Under the push of the first operating cylinder 802, the first connecting block 801 moves forward, thereby causing the first sliding block 10 and the second sliding block 11 to move forward, driving the second positioning block 3 mounted on the first sliding block 10 and the third positioning block 4 mounted on the second sliding block 11 to move forward. A sliding groove is provided on the workbench 1 along the movement direction of the first sliding block 10 and the second sliding block 11 to avoid interference with the workbench 1. The clamping plate 6 of the second positioning block 3 clamps one corner of the door and window body. The second operating cylinder 902 is then activated. A second connecting block 901 is fixed to the front end of the second operating cylinder 902. The second slide rod 14 passes through the ends of the second connecting block 901 and connects to the third and second sliding blocks 12, 11, respectively. The fourth positioning block 5 is fixed to the upper end surface of the third sliding block 12 with screws. Driven by the second operating cylinder 902, the second connecting block 901 moves forward, causing the third and second sliding blocks 12, 11 to move forward, driving the fourth positioning block 5 mounted on the third sliding block 12 and the third positioning block 4 mounted on the second sliding block 11 forward. Slots are provided on the workbench 1 along the direction of movement of the third and second sliding blocks 12, 11 to prevent interference with the workbench 1. The clamping plates 6 of the third positioning block 4 and the clamping plates 6 of the fourth positioning block 5 clamp the other two corners of the door and window body. A clamping assembly 7 is fixed to the diagonal of each positioning block. At the same time, cylinder 706 is activated, causing the output end of cylinder 706 to move upward, driving the second connecting rod 703 to rotate. The second connecting rod 703 is hinged to the upper end face of the first connecting rod 702 at its middle portion, causing the first connecting rod 702 to rotate accordingly. A bracket 704 is mounted at the front end of the second connecting rod 703. Bracket 704 is perpendicularly arranged to the second connecting rod 703. Clamping blocks 705 are mounted perpendicularly at both ends of bracket 704.

This clamps the door and window body around and on the upper end face, resulting in a simple structure and easy operation. This provides greater stability during machining. Once the door and window body is machined, cylinder 706 is activated, causing it to retract, causing the clamping blocks 705 mounted at the front end to tilt up, releasing the door and window body. Then start the first and second cylinders 802, 902, and retract, driving the upper positioning blocks to move along their respective slides, loosening the door and window bodies on all sides. Remove the door and window bodies.
