[0020] The drawings in this utility model are all schematic diagrams, and their sizes do not represent actual sizes;

[0021] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] like Figure 1 to Figure 4As shown, a helicopter manual press comprises: a support frame 1, a universal wheel 2 is symmetrically arranged at the bottom of the support frame 1, a fixed frame 6 is symmetrically arranged on the upper surface of the support frame 1, a stabilizing rod 7 is slidably connected to the top of the fixed frame 6, a moving frame 8 is fixedly connected to the stabilizing rod 7, a supporting plate 9 is fixedly connected to the top of the moving frame 8, an adjusting component 10 is fixedly connected to one side of the moving frame 8, and an adjusting component 10 for adjusting the height of the moving frame 8 is arranged on the support frame 1;

[0024] The adjustment assembly 10 includes a hydraulic rod 1001, which is symmetrically arranged on the upper surface of the support frame 1. The top of the hydraulic rod 1001 is slidably connected to a movable rod 1002, and the surface of the hydraulic rod 1001 is rotatably connected to a handle 1003. The movable rod 1002 is extended by pressing the handle 1003, and the height of the support plate 9 is adjusted by extending the movable rod 1002.

[0025] The bottom of the support frame 1 is threadedly connected with a threaded rod 3, the bottom of the threaded rod 3 is fixedly connected with a support foot 4, and the surface of the threaded rod 3 is fixedly connected with an adjusting screw 5. The height of the threaded rod 3 is adjusted by adjusting the adjusting screw 5, so that the support frame 1 is kept horizontal and the universal wheel 2 is off the ground.

[0026] The threaded rod 3 is symmetrically arranged at the bottom of the support frame 1, and a threaded hole matching the threaded rod 3 is provided on the support frame 1. The height of the threaded rod 3 is adjusted to make the universal wheel 2 leave the ground, so as to prevent the support frame 1 from moving and causing the parts to fall when the parts are disassembled. The height of the threaded rod 3 is adjusted to keep the support frame 1 level.

[0027] The top of the movable rod 1002 is fixedly connected to the mobile frame 8, and the hydraulic rod 1001 is arranged at the center of the top of the support frame 1. The movable frame 8 is driven to move upward by the movement of the movable rod 1002, and the height of the support plate 9 is adjusted by the movement of the mobile frame 8.

[0028] The support plate 9 has a through hole 11 on its surface, and the adjustment assembly 10 has a through hole matching the through hole 11. The through hole 11 is provided to facilitate the installation and removal of the tooling required for the parts.

[0029] Among them, the surface of the support plate 9 is provided with an acid-washed phosphating epoxy resin electrostatic coating, and the surface of the support plate 9 is provided with a groove 12 matching the adjustment component 10. The spray coating is used to extend the service life of the equipment, and the groove 12 is provided to facilitate the installation of tooling to disassemble the parts.

[0030] The diameter of the through hole 11 is 12 mm, the length of the mobile frame 8 is 820 mm, and the load-bearing capacity is 300 kg, which is sufficient for the maintenance of helicopter parts.

[0031] The working principle of the utility model is: the support plate 9 is moved to the desired position by the universal wheel 2, and the adjusting screw 5 is turned to drive the threaded rod 3 to rotate, thereby controlling the threaded rod 3 to move downward, driving the supporting foot 4 to extend downward, so that the universal wheel 2 is separated from the ground and the support plate 9 is kept horizontal. After reaching the desired position, the handle 1003 is pressed to push the movable rod 1002 upward, thereby adjusting the height of the support plate 9, which is convenient for adjustment according to actual conditions. The parts to be repaired are placed on the support plate 9, and the corresponding tooling is installed on the through hole 11 and the groove 12, and the tooling is used to facilitate the disassembly of the parts.

[0032] In addition, the torque and placement area required for component disassembly during daily maintenance can be checked in the Bell 407AMM manual. We design a manual press that meets the manual standards and can be used to apply sufficient torque ( Figure 1 , with a designed load of 300KG), and a groove 12 for placing special tools is designed on the manual press table, which is convenient for maintenance workers to approach the construction and allows the special tools for parts to be better placed on the table for easy disassembly. The manual press can completely solve the problem of damage to parts caused by insufficient torque.

[0033] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
