Abstract
The air operated flexibility universal spheric joint, its characteristic is by seals covers (1), seals the attachment (2), the rubber pipe (3), the tight circle (4), seals the attachment (5), seals covers (6) to compose, in seals covers (2) on to be separated 120 to be equipped with three threaded hole, in seals covers (6) on to be separated 120 to be equipped with three stairs holes, also stair hole pocket for threaded hole, three same rubber pipes (3) the about beginnings and ends separately with seal the attachment (2) and seal the connection (5) to connect, Seals the attachment (2) to seal through the thread covers (1) to connect, the tight circle (4) the tight wrap in the rubber pipe (3) outside, seals the attachment (5) to cover (6) through spiral Wen Yufeng to connect, is sealing the attachment (5) the center to suppose to pass the hole, causes the rubber pipe (3) the cavity and the atmosphere is interlinked. Its structure simple reasonable, movement nimble, control simple, the use effect is good, has the bigger implementation value.
Description
Technical field
The invention belongs to ball-joint, especially Pneumatic flexible ball joint is applicable to the occasion that designs and produces mechanical finger.
Background technique
The design in joint is a key technology during mechanical finger designs and produces, and the sensitivity in joint and the complexity of articulation structure directly determine the structure and the size of mechanical finger.Before the present invention made, traditional design philosophy is based on pure mechanical structure carried out, and its major defect is to add driving mechanism, needs motor or hydraulic pressure as driving, and bulk is big, complex structure, and the control difficulty influences implementation result.
Summary of the invention
The present invention has overcome the shortcoming of conventional method and prior art, provides a kind of simple and reasonable, and motion is controlled simple Pneumatic flexible ball joint flexibly.
Pneumatic flexible ball joint, it is characterized in that by left sealing cap 1, left side sealing joint 2, rubber pipe 3, fastening ring 4, right sealing joint 5 and right aling cap 6 are formed, 120 degree are provided with three tapped holes at interval on left sealing cap 1,120 degree are provided with three step holes at interval on right aling cap 6, and the macropore of step hole is a tapped hole, the two ends, the left and right sides of three same rubber pipes 3 are connected with right sealing joint 5 with left sealing joint 2 respectively, guarantee the sealing of connection between rubber pipe 3 and left sealing joint 2 and the right sealing joint 5, left side sealing joint 2 is connected with left sealing cap 1 by screw thread, fastening ring 4 tightly is enclosed within rubber pipe 3 outsides, and be positioned at right sealing joint 5 one ends, right sealing joint 5 is connected with right aling cap 6 by screw thread, establish a through hole at right sealing joint 5 centers, the mouth by relevant position on this through hole and the right aling cap 6 makes rubber pipe 3 inner chambers communicate with atmosphere.
The present invention compared with prior art, it is simple and reasonable, adopts pneumatics, mainly constitutes flexible ball joint by three rubber pipes, this ball-joint is simple and reasonable, motion flexibly, control is simple, using effect is good, has bigger implementary value.
Description of drawings
Fig. 1 is the Pneumatic ball joint structural representation.
Wherein: 1-left sealing cap, 2-left side sealing joint, 3-rubber pipe, 4-fastening ring, the right sealing joint of 5-, 6-right aling cap.
Embodiment
Fig. 1 is an an example of the present invention.As shown in Figure 1, embodiment of the present invention are: Pneumatic flexible ball joint, it is characterized in that by left sealing cap 1, left side sealing joint 2, rubber pipe 3, fastening ring 4, right sealing joint 5, right aling cap 6 is formed, 120 degree are provided with three tapped holes at interval on left sealing cap 1,120 degree are provided with three step holes at interval on right aling cap 6, and the macropore of step hole is a tapped hole, the two ends, the left and right sides of three same rubber pipes 3 are connected with right sealing joint 5 with left sealing joint respectively, guarantee the sealing of connection between rubber pipe 3 and left sealing joint and the right sealing joint 5, left and right sides sealing joint is connected with left sealing cap 1 by screw thread, fastening ring 4 tightly is enclosed within rubber pipe 3 outsides, and be positioned at right sealing joint 5 one ends, right sealing joint 5 is connected with right aling cap 6 by screw thread, establish a through hole at right sealing joint 5 centers, mouth by relevant position on this through hole and the right aling cap 6 makes rubber pipe 3 inner chambers communicate with atmosphere.Working principle of the present invention is: the inner chamber that pressurized gas is fed three rubber pipes 3 from the step hole on the right aling cap 6 by breathing pipe, feed the pressure of the pressurized gas of three rubber pipes 3 by control, can be so that whole joint bends to different directions, form the ball-joint of a flexibility, it is simple in structure, control is moved flexibly easily, has bigger implementary value.
