下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
参照图1-图4，一种工程机械液压油缸快速拆装装置，包括操作台1和液压油缸9，操作台1顶壁开设有滑槽12，滑槽12侧壁转动连接有双向丝杠19，双向丝杠19侧壁对称螺纹连接有滑块13，每个滑块13顶壁均固定连接有第一固定块8，每个第一固定块8顶壁均对称固定连接有第一螺纹杆10，同侧的两个第一螺纹杆10侧壁共同贯穿滑动连接有第二固定块7，液压油缸9一端贯穿滑动连接有活塞杆14，活塞杆14侧壁开设有销孔15，操作台1顶壁固定连接有安装板4，安装板4侧壁固定连接有电动装置5，电动装置5活动端固定连接有连接块6。Referring to Figures 1 to 4, a quick disassembly and assembly device of a hydraulic cylinder for engineering machinery includes an operating table 1 and a hydraulic cylinder 9. A slide groove 12 is provided on the top wall of the operating table 1. A bidirectional lead screw 19 is rotatably connected to the side wall of the slide groove 12. A slider 13 is symmetrically threadedly connected to the side wall of the bidirectional lead screw 19. A first fixed block 8 is fixedly connected to the top wall of each slider 13. A first threaded rod 10 is symmetrically fixedly connected to the top wall of each first fixed block 8. The side walls of the two first threaded rods 10 on the same side are penetrated together and slidably connected to a second fixed block 7. A piston rod 14 is penetrated and slidably connected to one end of the hydraulic cylinder 9. A pin hole 15 is provided on the side wall of the piston rod 14. A mounting plate 4 is fixedly connected to the top wall of the operating table 1. An electric device 5 is fixedly connected to the side wall of the mounting plate 4. A connecting block 6 is fixedly connected to the movable end of the electric device 5.
每个滑块13均与滑槽12侧壁相抵滑动，避免其带动第一固定块8产生旋转，导致无法对液压油缸9进行固定的问题，每个第一螺纹杆10侧壁均套设有弹簧11，每个弹簧11的一端均与对应的第一固定块8的顶壁固定连接，通过弹簧11对第二固定块7起到支撑和缓冲作用。Each slider 13 slides against the side wall of the slide groove 12 to prevent it from driving the first fixed block 8 to rotate, resulting in the problem that the hydraulic cylinder 9 cannot be fixed. A spring 11 is sleeved on the side wall of each first threaded rod 10, and one end of each spring 11 is fixedly connected to the top wall of the corresponding first fixed block 8, so that the second fixed block 7 is supported and buffered by the spring 11.
连接块6为圆筒形结构，其一端为开口，活塞杆14的一端能够插接进入连接块6的内部，连接块6侧壁贯穿滑动连接有第二螺纹杆16。The connecting block 6 is a cylindrical structure with one end being open. One end of the piston rod 14 can be inserted into the interior of the connecting block 6 , and a second threaded rod 16 is slidably connected to the side wall of the connecting block 6 .
每个第一螺纹杆10侧壁均螺纹连接有第一固定螺母17，第二螺纹杆16侧壁对螺纹连接有第二固定螺母18，通过第一固定螺母17和第二固定螺母18分别能够对第二固定块7和活塞杆14进行安装固定。Each side wall of the first threaded rod 10 is threadedly connected to a first fixing nut 17, and each side wall of the second threaded rod 16 is threadedly connected to a second fixing nut 18. The first fixing nut 17 and the second fixing nut 18 can be used to install and fix the second fixing block 7 and the piston rod 14 respectively.
双向丝杠19一端贯穿操作台1侧壁后固定连接有转手3，通过转动转手3带动双向丝杠19转动，能够使其侧壁对称螺纹连接的滑块13带动第一固定块8和第二固定块7移动，便于对其固定夹具的间隔进行调节，以适用于不同长度大小的液压油缸。One end of the bidirectional lead screw 19 passes through the side wall of the operating table 1 and is fixedly connected to a handle 3. By rotating the handle 3, the bidirectional lead screw 19 is driven to rotate, so that the slider 13 symmetrically threadedly connected to the side wall can drive the first fixed block 8 and the second fixed block 7 to move, so as to facilitate the adjustment of the interval of the fixing clamp to adapt to hydraulic cylinders of different lengths.
同侧的第一固定块8与第二固定块7侧壁共同开设有贯穿孔20，第一固定块8与第二固定块7共同夹持固定液压油缸9，操作台1底壁对称固定连接有支脚2。The side walls of the first fixing block 8 and the second fixing block 7 on the same side are jointly provided with a through hole 20 , and the first fixing block 8 and the second fixing block 7 jointly clamp and fix the hydraulic cylinder 9 , and the bottom wall of the operating platform 1 is symmetrically fixedly connected with the supporting legs 2 .
本实用新型中，将需要拆卸的液压油缸9穿过第一固定块8与第二固定块7侧壁共同开设的贯穿孔20，通过转动转手3能够带动双向丝杠19转动，从而使其侧壁对称螺纹连接的滑块13带动第一固定块8和第二固定块7移动，通过两个滑块13的相互远离或相互靠近，达到调节固定间距的效果，调节完成后压紧第二固定块7使其压缩弹簧11，并通过第一固定螺母17和第一螺纹杆10的螺纹连接将第二固定块7与第一固定块8抵紧固定。In the utility model, the hydraulic cylinder 9 to be disassembled is passed through the through hole 20 jointly opened on the side walls of the first fixed block 8 and the second fixed block 7. By turning the handle 3, the bidirectional screw 19 can be driven to rotate, so that the slider 13 symmetrically threadedly connected to the side wall drives the first fixed block 8 and the second fixed block 7 to move. The effect of adjusting the fixed distance is achieved by the two sliders 13 moving away from or approaching each other. After the adjustment is completed, the second fixed block 7 is pressed to compress the spring 11, and the second fixed block 7 is pressed and fixed to the first fixed block 8 through the threaded connection of the first fixing nut 17 and the first threaded rod 10.
进行拆卸时，电动装置5的活动端带动连接块6向着活塞杆14的方向移动，活塞杆14的一端插入连接块6后，通过活塞杆14侧壁开设的销孔15将第二螺纹杆16穿入，并通过第二固定螺母18进行固定，而后电动装置5反向运动，拉动活塞杆14使其从液压油缸9中拆下，无需通过手动或借助机械吊具进行拆卸；活塞杆14进行安装时，使得活塞杆14一端连接块6进行连接，而后通过电动装置5驱动其进入液压油缸9内部，从而能够达到快速拆装的效果。During disassembly, the movable end of the electric device 5 drives the connecting block 6 to move in the direction of the piston rod 14. After one end of the piston rod 14 is inserted into the connecting block 6, the second threaded rod 16 is inserted through the pin hole 15 opened on the side wall of the piston rod 14 and fixed by the second fixing nut 18. Then the electric device 5 moves in the opposite direction, pulling the piston rod 14 to remove it from the hydraulic cylinder 9, without the need for manual disassembly or with the help of mechanical lifting equipment; when the piston rod 14 is installed, the connecting block 6 at one end of the piston rod 14 is connected, and then it is driven by the electric device 5 to enter the interior of the hydraulic cylinder 9, so that the effect of quick disassembly and assembly can be achieved.
