Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamping devices, in particular to a hydraulically controlled clamping device. Background Art
[0002] In the prior art, processing tools are often manually loaded and unloaded, and manually tightened, which not only wastes a lot of time on loading and unloading, but also wastes manpower. If there is only one workpiece on a clamping device, loading and unloading is still very convenient, but the efficiency is too low. If multiple workpieces are processed at the same time, the manual operation will be relatively complicated, and the number of screws to be tightened will be relatively large.
[0003] Therefore, it is necessary to develop a new type of hydraulically controlled clamping device to replace manual tightening, improve work efficiency and reduce operation time. Utility Model Content
[0004] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides a hydraulically controlled clamping device, which replaces manual force with hydraulic pressure, improves work efficiency, reduces operation time, and also reduces manpower.
[0005] Technical solution: The utility model is a hydraulically controlled clamping device, characterized in that it includes an oil cylinder, the oil cylinder is fixed on an oil cylinder support block, the oil cylinder and the oil cylinder support block are connected through an oil inlet valve body, the oil cylinder is connected to an expansion screw, and the oil cylinder support block is connected to a transition plate.
[0006] Wherein, the oil cylinder piston on the oil cylinder is connected with the expansion screw inner core of the expansion screw.
[0007] Wherein, a spring is arranged outside the inner core of the expansion screw.
[0008] Wherein, the spring winding is arranged outside the inner core of the expansion screw.
[0009] Wherein, the oil inlet valve body is provided with an oil inlet port.
[0010] Wherein, the expansion screw is connected to an external workpiece.
[0011] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model replaces manual labor with hydraulic pressure, improves work efficiency, reduces operation time, and also reduces manpower. The whole process is simple and convenient to operate, and it is easy to get started. Moreover, the hydraulically controlled clamping device can control multiple cylinders at the same time to achieve simultaneous processing of multiple workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 It is a schematic diagram of multi-workpiece processing of the utility model;
[0014] In the figure, 1 is the oil inlet valve body; 2 is the oil cylinder support block; 3 is the oil cylinder; 4 is the transition plate; 5 is the expansion screw; 6 is the expansion screw inner core; and 7 is the oil cylinder piston. DETAILED DESCRIPTION
[0015] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0016] The hydraulically controlled clamping device of the utility model comprises an oil cylinder 3, the oil cylinder 3 is fixed on the oil cylinder support block 2, the oil cylinder 3 and the oil cylinder support block 2 are connected through the oil inlet valve body 1, the oil cylinder 3 is connected to the expansion screw 5, and the oil cylinder support block 2 is connected to the transition plate 4. Among them, the oil cylinder piston 7 on the oil cylinder 3 is connected to the expansion screw inner core 6 of the expansion screw 5. A spring is provided outside the expansion screw inner core 6. The spring is wound and arranged outside the expansion screw inner core 6. The oil inlet valve body 1 is provided with an oil inlet. The expansion screw 5 is connected to an external workpiece.
[0017] The utility model mainly fixes the oil cylinder 3 on the oil cylinder support block 2 in the whole hydraulic control clamping device, and then connects the oil cylinder 3 and the oil cylinder support block 2 with the oil inlet valve body 1, so that the oil inlet valve body 1 can supply oil to the oil cylinder 3. The piston on the oil cylinder 3 is connected to the inner core of the expansion screw 5, and the loosening and expansion of the expansion screw 5 are controlled by the movement of the piston of the oil cylinder 3. The expansion screw 5 is connected to the workpiece, and the loosening and expansion of the expansion screw 5 can load and unload the workpiece.
[0018] During use, the oil enters the oil cylinder 3 from the oil inlet port on the oil inlet valve body 1, and then enters the oil cylinder 3, pushing the piston rod in the oil cylinder 3, and the piston rod pushes the inner core of the expansion screw to loosen the expansion screw 5. After loosening the expansion screw, the workpiece is placed in the expansion screw 5. After the oil is disconnected, the oil will no longer enter the oil cylinder 3. There is no liquid pressure to push the piston in the oil cylinder 3. At this time, the inner core of the expansion screw 5 uses the spring force of the spring 6 to expand the expansion screw, so that the workpiece is completely fixed and can be processed normally.
[0019] The utility model adds a hydraulic control system on the original basis, which can not only process multiple workpieces at the same time, but also has relatively simple operation, and can replace manual tightening with hydraulic pressure, thereby improving processing efficiency and reducing assembly time of workpieces. It only needs to place the components on the clamping device, and then the loading and unloading of the components can be controlled by hydraulic pressure and springs.
