The utility model discloses realize according to following technical scheme:

as shown in fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5, an internal fixing device for a multifunctional thin-walled rotating member includes a base 1, an auxiliary clamping mechanism 2, a supporting mechanism 3, and a main clamping mechanism 4.

The base 1 is fixed on an external plane through a limiting element or a bolt; the supporting mechanism 3 is fixed on the base 1 by welding; the auxiliary clamping mechanism 2 is connected to the supporting mechanism 3 through threads; the upper part of the main clamping mechanism 4 is connected with the auxiliary clamping mechanism 2 through bolts, the lower part of the main clamping mechanism is fixed on a clamping spring supporting flange 120 through bolts, and the clamping spring supporting flange 120 is fixed on a base through bolts.

Further scheme:

In some operating conditions the base plate 124 is not placed horizontally on the ground, in which case the welding pattern and position of the support base may be adjusted accordingly.

Figure 6 shows the clamping in a non-standard installation.

The following problems are found in the conventional fixing mode through research:

inevitable vibration can occur in the transportation process, and when the mass of the rotating part is larger and the wall thickness is thinner, the rotating part can be subjected to plastic deformation, so that the critical dimension of the rotating part is out of tolerance or the critical gauge is damaged. In view of the use characteristics of large thin-wall parts, the remanufacturing can not be realized basically, and the large thin-wall parts can only be discarded in most cases. During transportation, the carrier can generate displacement perpendicular to the gravity direction, and when the mass of the goods is large, particularly when the goods are large-mass thin-walled parts, the displacement can cause severe collision between the bottom of the goods and the goods tray.

The traditional fixing method is usually used for fixing from the bottom, and when special transportation occasions are encountered, the fixing method can only be used for reloading after being disassembled, and cannot realize quick disassembly and assembly, so that the transportation efficiency is greatly reduced. When the fixed point cannot be fixed accurately due to random errors, system errors and the like, the inaccuracy of the fixed point may cause the thin-wall rotating member to deform irreversibly, so that the transportation difficulty is increased.

Working principle and solution:

when the novel clamping device clamps, an external torque is applied to the hexagonal block 113, the hexagonal block 113 transmits the torque to the auxiliary clamping upright column 106 to finally act on the stroke block 105, and the stroke block 105 converts the torque applied to the stroke block into axial displacement in the stroke pipe 102 through threads. The displacement is transmitted to the hexagonal block 113 in the same manner as described above, the hexagonal block 113 converts the displacement into a pressure to the clamping spring 116 through the pressure-reducing gasket 103, and the clamping spring 116 deforms by elastic deformation and extends in the radial direction thereof, thereby achieving a clamping action.

When the releasing action is performed, a reverse torque is applied to the hexagonal block 113, and the compression spring 104 plays a dominant role in transmitting the displacement.

Under one working condition, the clamping device is vertically placed on the carrier, the base 1 of the clamping device is parallel to the ground, the clamped piece is naturally placed on the base plate 123, the clamping is started, the clamped piece is not fixed on a plane after being clamped, the geometric center of the clamped piece is overlapped with the geometric center of the clamp after being clamped, the fixing is not realized during the whole clamping process, and the position of the clamped piece is also adjusted. Meanwhile, under the working condition, even if the carrier vibrates during transportation and generates acceleration opposite to the gravity direction, the mechanism can generate certain force to balance the acceleration (the value of the specific force is different according to the product model and is only explained conceptually). When the carrier generates radial force due to vibration, due to the characteristic of the fixing mode of the carrier, the force can be converted into kinetic energy by the clamping spring 116, and is finally released to the external environment by acting, so that rigid impact is not caused on the clamped part. Even if the clamping piece is subjected to rigid impact caused by external factors, the impact only causes damage to the surface of the clamping piece, and the damage to the geometric shape of the clamping piece is reduced.

In one operating condition, the base plate of the clamping device is required to be fixed parallel to the direction of gravity, i.e. to the wall surface, as shown in fig. 8. In order to balance this effect, the main clamp spring 116 of the clamping mechanism is non-standard mounted so that the clamping mechanism supports the entire clamped member. It should be noted that, in this installation mode, the clamping spring 116 may be selected from different types (length, material, surface treatment, shape, etc.) according to the material and characteristics of the clamped piece, and auxiliary mechanisms may be added as appropriate.

In an operating condition in which the base plate of the clamping device is required to be fixed to the ceiling of the vehicle, the clamping mechanism is subject to gravity in a manner which will cause a change in the distribution of the clamping force on the clamped elements, and in order to compensate for this change it is necessary to adjust the height of the clamped elements to within the effective clamping height.

In summary, the present disclosure can satisfy the fixing requirements in the conventional situations, and also can satisfy the basic requirements for fixing in the extreme situations and non-conventional situations in the conventional situations. Meanwhile, the flexible clamp is high in flexibility and convenient to disassemble and assemble, and can be operated on occasions without more professional equipment and tools by selecting proper configuration according to different working environments and clamping requirements. For some parts which are prone to failure, quick replacement can be achieved.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
