Detailed Description
The utility model provides an automatic tightening device for mechanical stretching formula nut, it is right below with the accompanying drawing the utility model discloses a detailed embodiment carries out further detailed description.
The utility model discloses an automatic tightening device for mechanical stretching formula nut can carry out the robot automation to mechanical stretching nut and screw up. On the basis of a special hydraulic wrench for a robot, mechanisms such as a screwing sleeve and a reaction force arm sleeve are integrated to realize automatic screwing of a mechanical stretching nut. In a preferred embodiment, the automated tightening device for a mechanical tension nut of the present invention may further integrate a torque sensor to record the actual torque during the tightening operation.
Fig. 2 is a schematic view of the automated tightening device for a mechanical tension nut of the present invention. As shown in fig. 2, the utility model discloses an automatic tightening device for tensile nut of mechanical type includes parts such as special hydraulic wrench 1 of robot, drive shaft 2, reset spring 3, screws up sleeve 4, and reaction arm of force sleeve 5. In fig. 2, the automated tightening device is used to mechanically tension the nut 6. In fig. 2, although a torque sensor is not shown, a torque sensor may be provided and integrated with the tightening sleeve 4. The torque sensor may also be provided as a separate unit from the tightening sleeve 4, if appropriate.
The connection relationship of the components and the function thereof are explained in detail below:
special hydraulic wrench for robot 1: the hydraulic wrench 1 for the robot mainly provides a tightening torque for tightening the mechanical tension nut 6, and various hydraulic wrenches for the robot may be used as long as the hydraulic wrench can provide the tightening torque.
Drive shaft 2: the driving shaft 2 is connected with the robot-dedicated hydraulic wrench 1 and the tightening sleeve 4, and is used for transmitting the driving force of the robot-dedicated hydraulic wrench 1 to the tightening sleeve 4 to drive the tightening sleeve 4 to rotate. The torque sensor can adopt a common torque sensor to monitor the tightening torque output by the special hydraulic wrench 1 for the robot, and the data is fed back to the control system, so that the special hydraulic wrench 1 for the robot can work according to the set torque. The torque value for tightening the sleeve may be set in advance as needed, for example, to a value of 30% or 70% of the target tightening torque, and the function of tightening the nut in steps may be implemented in cooperation with the control system.
The return spring 3: since the tightening device is not used vertically, but is generally horizontally aligned and tightened, the tightening sleeve 4 requires pressure to maintain the forward position. Thus, between the drive shaft 2 and the tightening sleeve 4, a return spring 3 is mounted, which presses against the tightening sleeve 4 so that the tightening sleeve 4 is held in a forward position, so that the raised areas of the tightening sleeve 4 under pressure engage in castellation correspondence of the upper part of the nut body of the mechanical tension nut 6.
Tightening the sleeve 4: as described above, the tightening sleeve 4 is pressed and rotated by the drive shaft 2 and the return spring 3. As mentioned above, under the action of the return spring 3, the protruding part of the tightening sleeve 4 is matched with the corresponding position of the castellation type gap at the upper part of the nut main body of the mechanical stretching nut 6 under pressure, and the mechanical stretching nut 6 is screwed under the rotation driving of the hydraulic wrench 1 special for robot.
Reaction arm sleeve 5: the reaction force arm sleeve 5 is connected with the hydraulic wrench 1 special for the robot into a whole. The screw thread of its sleeve inboard cooperates with the decorative pattern in the spline packing ring outside of mechanical stretching formula nut 6, screws up the bolt in-process at special hydraulic wrench 1 of robot, and the tightening torque that produces transmits on mechanical stretching formula nut 6's the spline packing ring through reaction arm of force sleeve 5, provides support reaction force for the tightening of mechanical stretching nut 6.
The following is an exemplary description of the specific work flow of the automated tightening device for a mechanically stretched nut according to the present invention. In one embodiment of the present application, the automated tightening procedure is as follows:
i. the robot carries the robot specific hydraulic wrench 1 part and aligns it on the mechanical tension nut 6 to be tightened. The robot may be realized by cylinder compression by means of other components such as a cylinder compression component in this alignment step;
ii, applying pressure to the reaction force arm sleeve 5 by the robot, and sleeving the reaction force arm sleeve on a spline washer of the mechanical stretching nut 6; this pressure application can be achieved by other auxiliary means, for example, preferably by cylinder oscillation on a float;
in the rotation process of the driving shaft 2, the robot enables a gap of the screwing sleeve 4 to be sleeved into a corresponding gap position of the mechanical stretching nut 6 under the assistance of the return spring 3;
the hydraulic wrench 1 for the robot starts to tighten the mechanical tension nut 6 according to the set torque, and records and feeds back the actual value through the torque sensor;
v. the robot carrier moves to the next bolt position after tightening.
The above process is repeated until all the bolts are tightened or tightened step by step.
The application also relates to a robot using the above automated tightening device for a mechanically stretched nut. In a preferred embodiment, the robot system can reserve an MES database interface so as to be convenient for accessing an MES system of a whole factory, thereby providing a basis for automatically tracing and recording suppliers of assembly parts, parameter performance, responsible personnel, fastening torque and equipment consumption and providing a basis for comprehensive intelligent manufacturing.
It should be noted that the above description is only illustrative and explanatory, and it should be understood by those skilled in the art that any modification and replacement of the present invention are within the protection scope of the present invention.
