[0030] like Figures 1-6 As shown, this specific embodiment adopts the following technical solution: it includes a placement plate 1 and a clamping plate 2, and four clamping plates 2 are suspended above the placement plate 1;

[0031] It also includes:

[0032] The movable frame 3 consists of two movable frames, which are respectively movably arranged on the front and rear sides of the upper part of the placement plate 1. Two sliders 4 are fixedly arranged at the bottom of the movable frame 3, and the sliders 4 are slidably arranged in the grooves 5 opened on the upper part of the placement plate 1.

[0033] The movable insert rods 6, of which there are four, are movably inserted on the left and right sides of the two movable frames 3 respectively. A movable block 7 is fixedly installed at one end of the movable insert rod 6. A first spring 8 is fixedly installed inside the movable block 7. The placement plate 1 is provided with a clamping position adjustment mechanism 9 connected to the movable frame 3. A guide rod 18 is fixedly installed inside the movable block 7. The first spring 8 and the extrusion rod 10 are both movably sleeved on the guide rod 18. The guide rod 18 can not only provide auxiliary guidance for the movement of the extrusion rod 10 and improve the movement stability of the extrusion rod 10, but also prevent the first spring 8 from bending during the compression process and reducing its service life.

[0034] Four extrusion rods 10 are movably inserted into four moving blocks 7 respectively. One end of the first spring 8 is fixedly connected to the extrusion rod 10, and one end of the extrusion rod 10 is fixedly connected to the clamping plate 2. A secondary clamping mechanism 11 is provided on the moving block 7.

[0035] Two bidirectional lead screws 12 are provided, which are respectively rotatably inserted into the slide grooves 5 on the left and right sides via bearings. The sliders 4 are rotatably mounted on the bidirectional lead screws 12 via threads. A motor 13 is fixedly installed on the front side wall of the placement plate 1. The output shaft of the motor 13 is connected to the bidirectional lead screws 12. A synchronizing rod 19 is rotatably installed in the placement plate 1 via bearings. The rear ends of the two bidirectional lead screws 12 are connected to the synchronizing rod 19 via bevel gear pairs. Through the cooperation of the synchronizing rod 19 and the bevel gear pairs, the synchronous rotation of the bidirectional lead screws 12 on both sides can be realized to ensure the consistency of the movement of the sliders 4 on the left and right sides and to avoid the tilting and jamming of the moving frame 3 caused by the inconsistent movement distance of the sliders 4 on the left and right sides.

[0036] The clamping position adjustment mechanism 9 includes:

[0037] Two movable blocks 9-1 are fixedly installed at the bottom center of two movable frames 3. The movable blocks 9-1 are movably installed in the movable groove 14 opened on the upper part of the placement plate 1. A rotating sleeve 9-2 is rotatably installed in the movable block 9-1 through a bearing.

[0038] There are two vertical rods 9-3, which are respectively inserted into two movable blocks 9-1 via bearings. A second double-acting screw 9-4 is rotatably installed in the movable frame 3 via bearings. The movable insert rod 6 is rotatably sleeved on the second double-acting screw 9-4 via threads. The upper end of the vertical rod 9-3 is connected to the second double-acting screw 9-4 via a bevel gear pair. The lower end of the vertical rod 9-3 is connected to the rotating sleeve 9-2 via a bevel gear pair.

[0039] The drive rod 9-5 is rotatably inserted into two movable slots 14 via bearings. A second motor 9-6 is fixedly installed in the middle of the front side wall of the placement plate 1. The output shaft of the second motor 9-6 is connected to the drive rod 9-5. Several ribs 9-7 are distributed on the drive rod 9-5 with equal rounded corners. Both the ribs 9-7 and the drive rod 9-5 are movably inserted into the rotating sleeve 9-2. By rotating the second bidirectional lead screw 9-4 and cooperating with the moving insert 6 and the moving block 7, the distance between the left and right clamping plates 2 can be adjusted. This allows the clamping plates 2 to be moved to a suitable clamping position when facing long door and window profiles, thus improving the clamping stability of long door and window profiles.

[0040] The secondary clamping mechanism 11 includes:

[0041] Lifting plate 11-1, there are two lifting plates 11-1, which are respectively movably arranged in the moving block 7 on the left and right sides of the extrusion rod 10. Guide blocks 11-2 are fixedly arranged on the left and right side walls of the extrusion rod 10. The guide blocks 11-2 are movably arranged in the inclined guide grooves 15 opened on the side walls of the lifting plate 11-1.

[0042] A lifting block 11-3 is fixedly mounted on the upper part of two lifting plates 11-1 and movably inserted into a moving block 7. A limit plate 11-4 is movably mounted inside the lifting block 11-3. A second spring 11-5 connected to the limit plate 11-4 is fixedly mounted inside the lifting block 11-3. A clamping frame 11-6 is movably inserted on the lifting block 11-3 and is fixedly mounted on the limit plate 11-4. Several slots on the clamping frame 11-6 are each equipped with a clamping rotating rod 11-7 rotatably mounted via a rotating shaft. After the clamping plate 2 clamps the side wall of the door and window profile, the guide block 11-2 and the lifting block 7 are used to... With the cooperation of the lowering plate 11-1, the lifting block 11-3, the clamping frame 11-6, and the clamping rotating rod 11-7 can move downward synchronously. The second spring 11-5 compresses the rebound force applied to the limiting plate 11-4, so that the clamping rotating rod 11-7 can apply a downward clamping force to the upper part of the door and window profile, improving the clamping stability of the door and window profile. A rubber pad 16 is fixedly installed on the side wall of the clamping plate 2, and a rubber sleeve 17 is fixedly sleeved on the clamping rotating rod 11-7. When clamping the door and window profile, the rubber pad 16 and the rubber sleeve 17 can generate a large friction force with the surface of the door and window profile, further improving the stability of the door and window profile in the clamping state.

[0043] When using this utility model, the door and window profile is placed on the upper part of the placement plate 1. When the door and window profile is long, the second motor 9-6 can be started. The second motor 9-6 drives the drive rod 9-5 to rotate. The drive rod 9-5 drives the two rotating sleeves 9-2 to rotate synchronously through the rib 9-7. The rotating sleeves 9-2 drive the vertical rod 9-3 to rotate through the bevel gear pair. The vertical rod 9-3 drives the second double-acting screw 9-4 to rotate through the bevel gear pair, so that the moving rod 6 moves to the outside of the moving frame 3, expanding the distance between the left and right moving blocks 7, and adjusting the clamping position of the clamping plate 2 on the longer door and window profile. Then, the first motor 13 is started. The first motor 13 drives the first double-acting screw 12 connected to it to rotate. With the cooperation of the synchronizing rod 19 and the bevel gear pair, the synchronous rotation of the first double-acting screws 12 on both sides can be achieved. At this time, the sliders 4 on the front and rear sides drive the two moving frames 3 to move synchronously in opposite directions. 3. By moving the insert rod 6, the moving block 7, and the pressing rod 10, the clamping plate 2 is moved towards the door and window profile. After the clamping plate 2 contacts the door and window profile, the moving frame 3 can continue to move, so that the pressing rod 10 gradually inserts into the inside of the moving block 7 and compresses the first spring 8, thereby clamping the front and rear sides of the door and window profile. The guide block 11-2 will also move in the inclined guide groove 15, so that the lifting plate 11-1 drives the lifting block 11-3 to move downward. 1-3 drives the clamping frame 11-6 to move downward, and the clamping frame 11-6 drives the clamping rotating rod 11-7 to move downward to contact the door and window profile. The limiting plate 11-4 will move upward within the lifting block 11-3 and compress the second spring 11-5. The rebound thrust applied by the second spring 11-5 to the limiting plate 11-4 can be applied to the upper part of the door and window profile through the clamping frame 11-6 and the clamping rotating rod 11-7, thereby achieving auxiliary clamping of the upper part of the door and window profile.

[0044] Compared with the prior art, the beneficial effects of this utility model are:

[0045] 1. Through the cooperation of the movable frame 3, movable insert rod 6, movable block 7, No. 1 spring 8, clamping position adjustment mechanism 9 and pressing rod 10, the clamping position can be adjusted according to the length specifications of the door and window profiles, thereby improving the clamping stability of longer door and window profiles.

[0046] 2. Through the cooperation of slider 4, secondary clamping mechanism 11, first bidirectional lead screw 12 and first motor 13, not only can the front and rear side walls of the door and window profiles be clamped, but the upper part of the door and window profiles can also be simultaneously clamped, so that the clamping stability of the door and window profiles is further improved.

[0047] 3. The guide rod 18 not only provides auxiliary guidance for the movement of the extrusion rod 10 and improves the movement stability of the extrusion rod 10, but also prevents the No. 1 spring 8 from bending during the compression process and reducing its service life.

[0048] 4. Through the cooperation of the synchronizing rod 19 and the bevel gear pair, the synchronous rotation of the first bidirectional lead screw 12 on both sides can be realized to ensure the consistency of the movement of the slider 4 on the left and right sides, and to avoid the movement distance of the slider 4 on the left and right sides being inconsistent, which would cause the moving frame 3 to tilt and jam.

[0049] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
