[0002] In the processing of molded door and window profiles, the clamping mechanism is a crucial equipment component. In the early days, the processing of door and window profiles mainly relied on manual operation, and the clamping methods were relatively simple, typically using simple clamps or manual support. This method was not only inefficient and labor-intensive, but also difficult to guarantee in terms of clamping stability and precision. This resulted in large dimensional errors in the processed door and window profiles, leading to inconsistent product quality and failing to meet the demands of large-scale production and high-quality construction.
[0003] In recent years, with the continuous improvement of the construction industry's requirements for the quality of doors and windows and the intensification of market competition, door and window manufacturers urgently need a more efficient, precise, and flexible clamping mechanism for pre-formed door and window profiles. Although some pre-formed door and window profile clamping mechanism products have appeared on the market, there are still some shortcomings in practical applications: because pre-formed door and window profiles come in various sizes, existing clamping mechanisms can either only perform double-point clamping on door and window profiles of a single size, or only single-point clamping. There is a lack of a pre-formed door and window clamping device that can adjust to the size of the door and window profile for double-point clamping. Utility Model Content

[0027] Example 1: Please see Figure 3 and Figure 5This embodiment proposes a clamping mechanism that can be used for clamping door and window profiles as well as for clamping long beams or long rods during production. The following description of the clamping mechanism 14 will focus on profile clamping. The mechanism includes a clamping seat 141, on which a drive pulley 142 is rotatably connected. The drive pulley 142 is driven to rotate by a drive component, which in this embodiment is a drive motor 143. A motor fixing plate 1415 is connected to the clamping seat 141, and the drive motor 143 is connected to the motor fixing plate 1415. The output end of the drive motor 143 is driven to connect with the drive pulley 142. Each end of the clamping seat 141 is connected to a driven pulley 144. The drive pulley 142 and the driven pulley 144 are connected by a transmission belt 145. Two connecting blocks 146 are fixedly connected to the transmission belt 145. One connecting block 146 is connected to the outer transmission belt 145, and the other connecting block 146 is connected to the inner transmission belt 145. The two connecting blocks 146 can move in opposite directions with the transmission belt 145. The bottom of the connecting block 146 is connected to a claw assembly, which can clamp the profile.
[0028] In addition, in order to ensure the normal use of the transmission belt 145, a tensioning pulley 1418 is provided between the drive pulley 142 and the driven pulley 144 to tension the transmission belt 145, so as to ensure that the transmission belt 145 can transmit normally without slipping.
[0029] The gripper assembly can use conventional opposing grippers. However, this embodiment proposes a gripper assembly including a gripper seat 147, which is fixed to a connecting block 146. A vertical guide rod 148 is fixedly connected to the gripper seat 147, and an upper clamping plate 149 is sleeved on the vertical guide rod 148. A lower clamping plate 1411 is fixedly connected to the bottom of the vertical guide rod 148. A cylinder fixing plate 1412 is also connected to the gripper seat 147, and a drive cylinder 1410 is connected to the cylinder fixing plate 1412. The telescopic end of the drive cylinder 1410 is connected to the upper clamping plate 149, enabling the upper clamping plate 149 to move vertically along the vertical guide rod 148. A guide slider 1413 is connected to the gripper seat 147. A guide rail 1414, corresponding to the gripper seat 141 and along the direction of the transmission belt 145, is provided to cooperate with the guide slider 1413. The guide slider 1413 and the guide rail 1414 guide the movement direction of the gripper assembly.
[0030] Working principle: First, start the drive motor 143 to rotate forward. The drive motor 143 drives the drive pulley 142 to rotate, and the drive pulley 142 drives the transmission belt 145 to move, causing the two connecting blocks 146 to move in opposite directions. When the required length of the profile is reached, turn off the drive motor 143. After the lower clamping plate 1411 of the clamping mechanism 14 abuts against the lower surface of the profile, start the drive cylinder 1410 to drive the upper clamping plate to press down and clamp the profile. When it is necessary to release the profile, simply reverse the above steps.
[0031] Example 2: Continue reading Figure 3 and Figure 5 Based on Embodiment 1, this embodiment connects L-shaped baffles 1416 to both ends of the clamping seat 141. The top of the L-shaped baffles 1416 is rotatably connected to the rotating shaft 1417, and the top of the rotating shaft 1417 is connected to the driven pulley 144. When the connecting block 146 moves to both ends of the clamping seat 141, it first touches the L-shaped baffles 1416. The baffles can prevent the connecting block 146 from directly impacting the driven pulley 144, thereby preventing damage to the driven pulley 144 and ensuring the stability of the device.
[0032] Example 3: Please see Figures 1-7 Based on the above embodiments, this embodiment proposes a molding door and window clamping device, including two sets of clamping units 1 arranged opposite to each other. Each set of clamping units 1 includes a crossbeam 11, a sliding seat 12 is slidably connected to the crossbeam 11, and a longitudinal moving component 13 is slidably connected to the sliding seat 12. The bottom of the longitudinal moving component 13 is connected to the clamping mechanism 14 described in Embodiment 1 or Embodiment 2.
[0033] A transverse motor plate 121 is connected to one side of the sliding seat 12. A transverse motor 122 is connected to the transverse motor plate 121. The output end of the transverse motor 122 is connected to a transverse gear 123. A transverse rack 124 is connected to the corresponding crossbeam 11. The transverse rack 124 and the transverse gear 123 cooperate to realize the transverse movement of the sliding seat 12. A transverse slide rail 125 is also provided on the crossbeam 11 along the direction of the transverse rack 124. A transverse slider 126 is fixedly connected to the corresponding sliding seat 12. The transverse slider 126 slides along the transverse slide rail 125 to guide the sliding seat 12.
[0034] In this embodiment, the longitudinal movement assembly 13 includes a longitudinal beam 131, a sliding seat 12 sleeved on the longitudinal beam 131, a longitudinal movement motor 132 connected to the top of the longitudinal beam 131, and a clamping mechanism 14 connected to the bottom of the longitudinal beam 131; a longitudinal movement screw 133 is vertically connected to the longitudinal beam 131, and the output end of the longitudinal movement motor 132 is connected to the longitudinal movement screw 133 for transmission; a longitudinal movement slider 134 is connected to the longitudinal movement screw 133, and the rotation of the longitudinal movement screw 133 can drive the longitudinal movement slider 134 to move along the longitudinal movement screw 133; vertical guide rails 136 are connected to both sides of the longitudinal beam 131, and vertical guide blocks 135 are connected to the corresponding sliding seat 12, and the vertical guide rails 136 and vertical guide blocks 135 cooperate to guide the vertical movement of the longitudinal beam 131. Since the longitudinal beam 131 is relatively long, in order to ensure its operational stability, an auxiliary cylinder 138 can be installed between the clamping seat 141 and the sliding seat 12. The auxiliary cylinder 138 is a driven component, ensuring that its vertical movement is always on a vertical straight line.
[0035] Finally, a limiting block 137 is connected at the top of the longitudinal beam 131, flush with the vertical guide rail 136. The limiting block 137 can prevent the vertical guide block 135 from derailing when the vertical guide rail 136 moves to the lowest position.
[0036] Working principle: The sliding seat 12 is moved laterally along the crossbeam 11 by the transverse motor 122, and the clamping mechanism 14 is moved downward by the longitudinal motor 132, so that the clamping mechanism 14 reaches both ends of the window profile conveyed by the conveying rollers. The clamping mechanism 14 is activated to clamp the window profile. If the window profile is rectangular, the two opposite clamping units 1 clamp the two sides of the window profile respectively to achieve clamping. After clamping, the window profile is moved upward and laterally to the storage area.
[0037] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
