Referring to fig. 1, an embodiment of the present utility model is provided:
The flexible universal fixing seat comprises a cylinder body 8, wherein the interior of the cylinder body 8 is divided into an upper chamber and a lower chamber through a partition plate; the top of the cylinder body 8 is in threaded connection with a gland 15, and the bottom of the cylinder body 8 is in threaded connection with a negative pressure air inlet base 1; the cylinder body 8 is internally provided with a locking slide block 17 which can move up and down in the cylinder body, the locking slide block 17 is of a ladder-shaped structure, the large diameter end of the locking slide block 17 is arranged in an upper cavity of the cylinder body, and the small diameter end of the locking slide block passes through a center hole of the partition plate (81) and a lower cavity of the cylinder body (8) and is movably connected with a center vent hole of the base (1).
The large diameter end of the locking slide block 17 is an inner cavity, and a rotary ball 13 is embedded in a spherical cavity formed by the upper port of the locking slide block and the central hole of the gland 15. The rotating ball material is elastic material, such as rubber, so that the rotating ball can be tightly attached to the curved material surface, and no air leakage phenomenon occurs. The spin ball is partially exposed from the gland 15 to achieve as large a spin range as possible, allowing the spin ball or an adsorption mechanism attached to the spin ball to better and more adhere to the curved material surface.
The locking slide block 17 is mainly used for propping up the locking slide block 17, fixing and locking the rotating ball 13 in the concave hole curved surface of the gland 15, fixing the rotating ball with the curved surface material at a well-arranged angle, and guaranteeing that the curved surface material is firmly adsorbed and fixed.
The center of the rotating ball (13) is provided with a vent hole (14), the lower opening of the rotating ball is communicated with a locking slide block center vent hole (16), and the inlet end of the center vent hole of the base (1) is a negative pressure air pipe joint mounting hole (4);
Example 2, see FIG. 1
In the embodiment, a gap eliminating spring (10) is arranged at the bottom of the inner cavity of the large-diameter end of the locking slide block 17, a gap eliminating ring (11) is arranged at the top of the gap eliminating spring (10), and the gap eliminating ring (11) is embedded between the rotating ball (13) and the inner wall of the large-diameter end. The gap eliminating ring has a plurality of functions, and the elasticity of the gap eliminating ring can support the rotating ball and enable the rotating ball to move under slight external force; the gap between the rotary ball (13) and the gap eliminating ring (11) can be sealed, so that negative pressure gas entering from the negative pressure air pipe joint mounting hole can normally reach the vent (14) through the locking slide block vent hole (16) when the rotary ball (13) is at different working angles.
Example 3 (see fig. 1, 2, 3):
in the embodiment, an unlocking piston 6 is arranged in a lower chamber of a cylinder body 8, and the unlocking piston 6 is fixedly arranged on a small-diameter end of a locking sliding block 17 through a nut 5; the outer wall of the cylinder body 8 is provided with a compressed air pipe joint mounting hole 18, and the compressed air pipe joint mounting hole 18 is communicated with the lower chamber. Thus, after compressed gas is introduced into the compressed gas pipe joint mounting hole, the rotary ball 13 is released; after the air is cut off, the rotary ball 13 can be locked and fixed, so that the adjustable sucker can be locked and released freely, the real-time adsorption fixation of materials with different curved surfaces can be realized, the adsorption fixation can be controlled remotely, or the adsorption fixation can be controlled automatically by a mechanical arm, and the application range is wider and the occasions are wider.
The specific principle is as follows:
After compressed gas is introduced into the compressed air pipe connector mounting hole, the compressed gas enters a lower cavity of the cylinder body from the pipeline, the unlocking piston 6 is pushed to move downwards, the locking sliding block 17 is driven to move downwards, the compression spring 9 is pressed and shortened, the constraint of the rotary ball 13 is released, the rotary ball 13 can freely rotate along with the curved surfaces of materials with different curved surfaces so as to adapt to the curved surfaces of the sucked materials, when the most suitable and stable bonding surface is reached (the rotary ball does not freely slide on the curved surfaces of the materials any more), the compressed gas is disconnected, the compression spring 9 is decompressed and rebounded, the locking sliding block is pushed upwards, the locking sliding block moves upwards, the rotary ball 13 is locked and fixed, and the curved surface materials can be adsorbed and fixed at a new angle.
Example 4 (see fig. 1, 2, 3):
In this embodiment, rotatory 13 top surface air vent rings are equipped with the seal groove, and the inslot inlays has the sealing washer to make rotatory ball and curved surface material closely laminate, guarantee the vacuum degree of contact surface, have simple structure, efficient beneficial effect.
Example 5 (see fig. 1, 2, 3):
In this embodiment, the material of the rotating ball 13 is elastic rubber, so that the periphery of the vent hole of the rotating ball is equivalent to a sealing ring, so that the rotating ball and the curved surface material can be tightly attached, and the air leakage phenomenon can not occur on the joint surface of the rotating ball and the curved surface material, thereby ensuring that the rotating ball can adsorb and fix the curved surface material. The structure is simpler, the operation is more convenient, and the device is lighter and more exquisite.
Example 6 (see FIGS. 1, 2, 3)
In this embodiment, the upper port of the rotary ball vent 14 is provided with mounting threads for mounting various types of suction cups.
After the ordinary sucking disc adsorbs fixed curved surface material, the operational angle of sucking disc can not change, is difficult to adapt to curved surface material surface change and adjusts the operational angle of sucking disc, and the sucking disc can't laminate on curved surface material's surface completely to influence the vacuum between sucking disc and the curved surface material surface, cause the actuation not firm. After the sucker is additionally arranged on the rotating ball of the flexible universal fixing seat, the sucker can slide on the surface of the curved surface material under the action of the mutual contact force of the sucker and the curved surface material, and the direction and the angle of the sucker can be freely adjusted along with the curved surface change of the curved surface material, so that the sucker can be more tightly attached to the surface of the curved surface material, and the fixed curved surface material is more stable and effective to absorb. In addition, because the area of the sucker is large, the material can be softer and more elastic, so that the material with larger and more complex curved surface can be adsorbed and fixed in a vacuum state.
