Detailed Description
The invention provides a device capable of realizing automatic quick connection with single degree of freedom for the in-orbit construction application background of space infrastructure (such as space-based radar) and the like, and has the advantages of small volume, simplicity in operation, high connection rigidity, high precision and the like. Compared with a scheme of CN201520392322.5 'a quick connection joint' by using steel balls and clamping grooves, the invention has simpler and more reliable working principle and is suitable for unmanned operation in a space complex environment.
The invention relates to a high-rigidity quick connecting device for on-orbit quick construction, which can connect two flat plates with high rigidity and precision through single-degree-of-freedom operation. As shown in fig. 1, the present invention is directed to an automated quick connection device for on-track construction, comprising: the special wedge block 1, the locking fastening device cover 2, the spring 3, the headless screw 4, the main body structure 5, the disc spring 6, the special screw 7, the M4 screw 8 and the M3 screw 9.
The main body structure 5 is located on the lower end face of the connecting piece B11, and a plurality of counter bores are uniformly distributed on the lower end face of the main body structure 5 in the circumferential direction as shown in fig. 2. A special wedge block 1 is arranged in each counter bore on the lower end face of the main body structure 5, and one end of each special wedge block 1 is fixedly connected with one end of a spring 3; the other end of the spring 3 is fixedly connected with the wall surface of the main structure 5 through a headless screw 4. The special wedges 1 can move inwards in the radial direction under the elastic force of the springs 3.
The locking fastening device cover 2 and the main body structure 5 are fixedly connected through M3 screws 9 to form an integral structure, and the integral structure formed by the locking fastening device cover 2 and the main body structure 5 is fixedly connected with the lower end face of the connecting piece B11 through M4 screws 8. The root of the stud of the special screw 7 is fixedly provided with a disc spring 6, and the free end of the special screw 7 is provided with a notch structure which is uniformly distributed in the circumferential direction.
Through holes matched in position are processed on the connected piece A10, the connected piece B11, the locking fastening device cover 2 and the main body structure 5; the size of the through hole is in clearance fit with the stud of the special screw 7.
The axial position of the notch structure of the special screw 7 is matched with the special wedge block 1. The tailored wedge 1 cannot rotate relative to the body structure 5. The section of the counter bore of the main body structure 5 is rectangular.
The tightening directions of the M4 screw 8 and the M3 screw 9 are opposite.
The number of the special wedges 1 is 3. In the embodiment of the invention, 3 specially-made wedges 1 are circumferentially and uniformly distributed at 120 degrees. The surface of the special wedge block 1 is subjected to solid lubrication treatment, such as MoS2 spraying. The lower surfaces of the 3 tailored wedges 1 are coplanar.
The deadlocking fastener cover 2 and the body structure 5 are connected by M3 screws 9. The locking fastening device cover 2 and the main body structure 5 are integrally connected with the connected piece through M4 screws 8. One end of the spring 3 is inserted into the tail end of the special wedge block 1, the other end of the spring is inserted into a hole in the main structure 5, and the elasticity of the spring 3 is adjusted through the headless screw 4. The special wedge block 1 is placed in the groove of the main structure 5, and the purpose that the special wedge block 1 has one degree of freedom to slide in the groove of the main structure 5 can be achieved. The disc spring 6 is sleeved in a special screw 7 in advance.
With reference to fig. 3, before operation, the disc spring 6 is inserted into the special screw 7 in advance. The deadlocking fastener cover 2 and the body structure 5 are connected by three M3 screws 9.
With reference to fig. 4, the locking fastener cover 2 and the body structure 5 are integrally connected to the connecting member B by three M4 screws 8. A through hole is drilled in advance on the connected piece A10 and the connected piece B11 respectively, and when the connecting piece is used, a special screw 7 sleeved with the disc spring 6 is inserted into the connected piece A10 and the connected piece B11. With reference to fig. 5, continuing to apply downward pressure to the special screw 7, the vertebral surfaces at the lower end of the special screw 7 compress the special wedge 1, causing the special wedge 1 to move along the groove of the body structure 5 away from the axis while compressing the spring 3. Referring to fig. 1, until the special wedge block 1 is ejected and is clamped into the front groove of the special screw 7, at this time, the disc spring 6 is compressed to a certain degree and can provide a larger elastic force, so that the connected member a10 and the connected member B11 are successfully connected.
As shown in fig. 1, the high-rigidity quick connection device of the present invention is suitable for connection between two flat plates, and can eliminate a connection gap while realizing quick connection by pre-tightening of the disc springs, and finally the compression stiffness of the connected member is represented as the structural stiffness of the connected member, and the tensile stiffness is determined by the compression stiffness of the disc spring set, and can be adjusted by increasing or decreasing the number of the disc springs or the positions of the grooves.
The high-rigidity quick connecting device can directly realize higher tension and compression rigidity, and if higher shearing rigidity of two connected pieces is required, the high-rigidity quick connecting device can be indirectly realized through larger pretightening force of the high-rigidity quick connecting device by designing a high-friction coating at the contact surface of the connected pieces; if the high bending rigidity of the two connected pieces is required to be obtained, 3-4 high-rigidity quick connecting devices can be arranged at the connecting position, and a certain span is provided between each point on the layout.
The high-rigidity quick connecting device has a self-alignment function, the length of the groove of the special screw 7 is larger than the height of the special wedge blocks 1, and the lower surfaces of the three groups of special wedge blocks 1 are in a coplanar relation with higher precision. In the rapid process, the special screw 7 extrudes the arc surfaces at the upper ends of the three groups of special wedges 1 in the main structure 5 through the large-angle chamfers at the ends (the arc surfaces are lubricated by molybdenum disulfide on the surfaces), the springs 3 at the roots of the special wedges 1 are compressed to realize longitudinal insertion, when the disc springs 6 are attached to the upper surface of the disc spring 10 under external thrust and are compressed and deformed to a certain amount, the three special wedges 1 are ejected into the grooves prefabricated at the lower ends of the special screws 7, the lower surfaces of the wedges are flat, and the lower surfaces of the three wedges are coplanar and closely attached to and aligned with the lower surfaces of the grooves of the special screw 7.
