The two sets of jaws 7 can clamp materials of various shapes in sequence. This implementation In the example, take clamping pipe as an example. When in use, the cylinder 9 is used as power, which is convenient for moving the jaws 7 and adjusting the clamping force of the jaws 7, so as to prevent damage to the material due to excessive pressure.
当需要启用第二组卡爪7b时，将管材伸入安装管内，驱动第一组气缸9a使第一推杆14伸出，使第三安装盘10相对第二安装盘8移动，带动第二组第一传动机构11传动，即第六齿轮11b3在第六滑槽10d内旋转，第五齿轮11b2随着第六齿轮11b3旋转，使第二齿条11b1朝向夹持装置的中心移动，从而使第二组卡爪7b中的两个卡爪7相互靠近卡住管材。反之，当需要松开管材时，驱动第一组气缸9a使第一推杆14缩回即可。When the second group of claws 7b needs to be activated, the pipe material is inserted into the installation pipe, and the first group of cylinders 9a are driven to extend the first push rod 14, so that the third installation disk 10 moves relative to the second installation disk 8, and drives the second installation disk 8. The first transmission mechanism 11 drives, that is, the sixth gear 11b3 rotates in the sixth chute 10d, and the fifth gear 11b2 rotates with the sixth gear 11b3, so that the second rack 11b1 moves toward the center of the clamping device, so that The two claws 7 in the second group of claws 7b are close to each other to clamp the pipe. Conversely, when it is necessary to loosen the pipe material, it is enough to drive the first group of cylinders 9a to retract the first push rod 14 .
当需要启用第一组卡爪7a时，将管材伸入安装管内，驱动第二组气缸9b使第二推杆16伸出，使第三安装盘10和第二安装盘8同时移动，带动第一组第一传动机构11传动，即第四齿轮11a3在第二滑槽8c内旋转，第三齿轮11a2随着第四齿轮11a3旋转，使第一齿条11a1朝向夹持装置的中心移动，从而使第一组卡爪7a中的两个卡爪7相互靠近卡住管材。反之，当需要松开管材时，驱动第二组气缸9b使第二推杆16缩回即可。When the first group of claws 7a needs to be activated, the pipe material is inserted into the installation pipe, and the second group of cylinders 9b is driven to extend the second push rod 16, so that the third installation disk 10 and the second installation disk 8 move simultaneously, driving the second installation disk 10 and the second installation disk 8 A set of first transmission mechanism 11 drives, that is, the fourth gear 11a3 rotates in the second chute 8c, and the third gear 11a2 rotates with the fourth gear 11a3, so that the first rack 11a1 moves toward the center of the clamping device, thereby Make the two claws 7 in the first group of claws 7a close to each other to clamp the pipe. Conversely, when it is necessary to loosen the pipe material, it is enough to drive the second group of cylinders 9b to retract the second push rod 16 .
所述底座1包括底板101和两个侧板102，所述底板101顶部安装所述侧板102，所述夹持装置安装在所述底板101顶部且位于两个所述侧板102之间。所述底座1顶部安装有第二电机18，所述底座1底部设有导轨103，所述底座1通过所述导轨103可滑动的安装在激光切割机的机床上，所述机床上固定有与所述导轨103相匹配的第二滑轨，所述第二滑轨与所述第二电机18之间通过第二传动机构连接。在本实施例中，所述第二传动机构包括第三齿条和第七齿轮，所述第三齿条安装在所述导轨103上，所述第三齿条与所述第七齿轮啮合，所述第七齿轮安装在所述第二电机18上。The base 1 includes a bottom plate 101 and two side plates 102 , the side plate 102 is installed on the top of the bottom plate 101 , and the clamping device is installed on the top of the bottom plate 101 and located between the two side plates 102 .
