When inspecting and repairing a hydraulic device in an aircraft, it is necessary to disassemble or assemble a piston rod in a hydraulic cylinder. In the prior art, a specific device is usually required to grab and fix the piston rod in the process of assembling and disassembling the piston rod, but the device can only fix the hydraulic rod without circumferential rotation, and the purpose of controlling the axial movement of the hydraulic rod is difficult to achieve.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned prior art not enough, provide a piston rod combined type fixing device to guarantee that the piston rod is when not taking place the pivoted, any removal does not take place for the axial.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a piston rod composite fixing device comprises a base and a metal plate; wherein,
a cylindrical cavity matched with the diameter of the piston rod is arranged in the base, convex ribs corresponding to the grooves of the piston rod are distributed on the inner wall of the cylindrical cavity, and a base mounting hole is formed in the top end face of the base;
the two metal plates are spliced into a synthetic body which has the same appearance as the base and the diameter of the inner wall of the cylindrical cavity of the base is slightly smaller than that of the inner wall of the cylindrical cavity of the base, so that the rod body of the piston rod is clamped; and each metal plate is provided with a metal plate mounting hole matched with the base mounting hole so as to fix the metal plate on the base.
The convex ribs are provided with six rectangular ribs which are positioned on the same horizontal plane and evenly distributed at the bottom of the inner wall of the cylindrical cavity.
The base mounting hole and the metal plate mounting hole are both screw holes.
The base is in a square shape
Compared with the prior art, the utility model, its beneficial effect lies in:
the utility model discloses piston rod combined type fixing device can directly be used for hydraulic system dismouting in-process, is responsible for snatching and fixing of piston rod. The metal plates of the device are disassembled, the piston rod is placed in the cavity of the base, the groove at the bottom of the piston rod is meshed with the positioning convex rib on the inner wall of the base, after the piston rod is fixed and cannot rotate, the two metal plates are spliced above the base and are matched with the screw holes in the two sides in a corresponding mode, and then the metal plates and the base are fixed through matched bolts. The positioning convex rib at the lower part is meshed with the groove, and the piston rod is locked by the upper metal plate, so that the piston rod is completely and fixedly grabbed in the cavity of the device. The whole operation is convenient and fast, the fixing reliability of the tool to the piston rod can be guaranteed, and resources consumed by work are saved.

fig. 2 is a front view of the piston rod composite fixing device provided in the embodiment of the present invention;
FIG. 3 is a diagram of a piston rod workpiece structure adapted to the present embodiment;
in the figure: 10. a base; 11. a cylindrical cavity; 12. a rib is protruded; 13. a screw hole; 20. a metal plate; 21. and a screw hole.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example (b):
referring to fig. 1-2, the piston rod composite fixing device provided by the embodiment includes a base 10, the base 10 is a square metal base, so as to facilitate production and manufacturing, an axial portion of the base 10 has a cylindrical cavity 11 with a diameter matched with a diameter of a piston rod (shown in fig. 3) of a corresponding model, the inner wall of the cylindrical cavity 11 has six positioning ribs 12, the positioning ribs 12 are cuboids, are located on the same horizontal plane and are evenly distributed below the inner wall of the cavity 11, and the top end face of the base 10 has six screw holes 13.
There are two identical metal sheets 20 above base 10, and metal sheet 20 can splice into an appearance and base, the same synthetic body that its cylinder cavity inner wall diameter slightly is lighter than base cylinder cavity inner wall diameter, has screw 21 with screw 13 position matching on every metal sheet 20, can be with metal sheet 20 fixed concatenation on the base. The bolt can be quickly installed through the screw holes 13.
The operation process of the composite piston rod fixing device is as follows:
1. the metal plate 20 is detached, one end of the piston rod, which needs to be operated, with the groove is placed into the cylindrical cavity 11, and the position of the piston rod is adjusted, so that the groove is completely meshed with the positioning convex rib 12, and the purpose of positioning is achieved;
2. keeping the relative perpendicularity of the piston rod and the base 10, putting the metal plate 20 on the base, and enabling the screw hole 21 and the screw hole 13 to be completely superposed, and clamping the rod body of the piston rod by the metal plate 20;
3. the metal plate 20 is tightly connected with the base 10 by screwing the bolt into the screw hole 21 and the screw hole 13, thereby achieving the purpose of completely fixing the piston rod.
Therefore, the utility model discloses piston rod combined type fixing device can directly be used for hydraulic system dismouting in-process, is responsible for snatching and fixing of piston rod. The metal plates of the device are disassembled, the piston rod is placed in the cavity of the base, the groove at the bottom of the piston rod is meshed with the positioning convex rib on the inner wall of the base, after the piston rod is fixed and cannot rotate, the two metal plates are spliced above the base and are matched with the screw holes in the two sides in a corresponding mode, and then the metal plates and the base are fixed through matched bolts. The positioning convex rib at the lower part is meshed with the groove, and the piston rod is locked by the upper metal plate, so that the piston rod is completely and fixedly grabbed in the cavity of the device. The whole operation is convenient and fast, the fixing reliability of the tool to the piston rod can be guaranteed, and resources consumed by work are saved.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
