The tooling structure provided by the embodiment of the invention is shown in fig. 2, and comprises: rotary part 1 and frock frame 2. Referring to fig. 3 and 4, the rotating member 1 includes a rotating plate 11, a fixed plate 12, a lift pin 13, and a suction cup 14.
Specifically, the fixed plate 12 is arranged on the tool frame 2, and the rotating plate 11 is rotatably connected with the fixed plate 12; the push rod 13 is arranged on the rotating plate 11, the sucker 14 is arranged on the fixed plate 12, and the orientation of the push rod 13 is consistent with that of the sucker 14.
In the embodiment of the invention, the tooling frame 2 is a fixed component, when a stringer skin needs to be subjected to hole-making riveting, as shown in fig. 5 and 6, the stringer 4 is fixed at a preset position of the tooling structure, and then the rotating plate 11 is rotated, so that the ejector rods 13 can tightly push the stringer 4, and an outward acting force can be applied to the stringer 4; then, the skin 5 is attached to the stringer 4, and the skin 5 is absorbed by the suction cups 14, so that the suction cups 14 can apply inward acting force to the skin 5; under the action of the ejector rods 13 and the suction cups 14, the stringer 4 and the skin 5 are tightly attached, and the subsequent hole-making and riveting process is facilitated. Optionally, a plurality of ejector rods 13 and a plurality of suction cups 14 may be provided, and the plurality of ejector rods 13 and the plurality of suction cups 14 are uniformly distributed, so that the stringer 4 and the skin 5 are uniformly stressed, the degree of fitting between the stringer 4 and the skin 5 is higher, and the skin 5 is not easily deformed. Meanwhile, the tool structure may be provided with a plurality of rotating members 1, and fig. 2 illustrates that seven rotating members 1 are included.
According to the tool structure provided by the embodiment of the invention, the stringer is tightly propped by the ejector rod, and the skin is adsorbed by the sucker, so that opposite acting forces can be provided for the stringer and the skin, the stringer and the skin can be tightly attached, and the skin and the stringer are not easy to deform; the tool structure does not need to arrange a pressing plate outside the skin, the outer surface of the skin cannot be shielded, the sectional area of the ejector rod is small, and the contact area between the ejector rod and the stringer can be ignored, so that the tool structure hardly influences hole making, and the hole making coverage rate is improved; meanwhile, riveting work can be continuously carried out after the hole making operation is finished, the workpiece does not need to be structurally dismounted from the tool, and the hole making and riveting integrated tool can be realized.
alternatively, as shown in fig. 4 and 6, the back surface of the fixing plate 12 is a contoured surface 122 that matches the surface to be loaded with the workpiece. In the embodiment of the present invention, the back surface of the fixing plate 12 needs to support the skin, that is, the back surface of the fixing plate 12 matches the surface curvature of the skin, etc., that is, the back surface of the fixing plate 12 is a contoured surface 122 matching the surface of the skin. The use of this contoured surface 122 enables the fixation plate 12 to better conform to the surface of the skin 5, further preventing deformation of the skin 5.
on the basis of the above embodiment, referring to fig. 7, the rotating member 1 further includes: a mounting bracket 15, a clamping disc 16 and a shaft seat 17; the mounting bracket 15 is arranged on the side surface of the fixing plate 12 and fixed on the tool frame 2; the clamping disc 16 is arranged on the mounting bracket 15; the base of the shaft seat 17 is fixed on the side surface of the rotating plate 11, and the rotating shaft of the shaft seat 17 penetrates through the clamping disc 16.
in the embodiment of the invention, the rotating component 1 is fixedly mounted on the tool frame 2 through the mounting bracket 15, and can be fixed through bolts. Meanwhile, the rotating plate 11 rotates around the rotating shaft of the shaft seat 17, so that the rotating connection between the rotating plate 11 and the fixed plate 12 is realized. Meanwhile, the shaft seat 17 can be clamped by the clamping disc 16, so that the position of the rotating plate 11 is fixed by the rotating disc 16 after the rotating plate 11 is rotated to the position, and the rotating plate 11 is prevented from rotating again after being rotated to the position. In addition, the rotating shaft of the shaft seat 17 is eccentrically arranged, i.e. the rotating shaft is located at the edge of the shaft seat 17. As shown in fig. 6, the rotating shaft is illustrated in fig. 6 as being located at a right angle of the shaft seat 17.
alternatively, as shown in fig. 6 and 7, the clamping plate 16 includes an adjustment knob 161, and the adjustment knob 161 is fixedly connected to the adjustment bolt of the clamping plate 16. The clamping operation can be performed easily and effortlessly by the adjustment knob 161, so that the shaft seat 17 can be clamped. In addition, as shown in fig. 2, a handle 111 may be disposed on the rotating plate 11, and the rotating plate 11 can be rotated by the handle 111, which is convenient and labor-saving.
optionally, referring to fig. 2, the rotating member 1 further includes: a hinge 18; two ends of the hinge 18 are respectively fixed on the rotating plate 11 and the fixed plate 12, and the rotating shaft of the hinge 18 is concentric with the rotating shaft of the shaft seat 17. In the embodiment of the present invention, the rotating connection between the rotating plate 11 and the fixed plate 12 is realized by using the hinge 18. Meanwhile, since the rotation plate 11 rotates around the rotation shaft of the shaft seat 17, it is required that the rotation shaft of the hinge 18 is concentric with the rotation shaft of the shaft seat 17 so that the rotation plate 11 can normally rotate. Wherein, the rotating component 1 may include a plurality of hinges 18, which is illustrated in fig. 2 by including three hinges as an example; meanwhile, one or more damping hinges may be provided to achieve cushioning during rotation. For example, the center one of the three hinges in fig. 2 may be set as a damping hinge.
On the basis of the above embodiment, the tool structure can also realize tangential adjustment of the rotating component 1. Specifically, the mounting bracket 15 is fixedly connected to the side surface of the fixing plate 12 through a kidney-shaped hole. As shown in fig. 7, the mounting bracket 15 is fixedly connected to the fixing plate 12 by a bolt 154, and at this time, a through hole of the bolt 154 passing through the mounting bracket 15 may be a kidney-shaped hole, so that the relative position between the mounting bracket 15 and the fixing plate 12 is adjustable.
Meanwhile, as shown in fig. 7 and 8, the mounting bracket 15 is provided with a tangential adjusting bolt 152, and the tangential adjusting bolt 152 is arranged along the width direction of the fixing plate 12; the fixing plate 12 is provided with a tangential adjusting screw hole 121 corresponding to the tangential adjusting bolt 152.
The tangential adjustment in the embodiment of the invention refers to adjustment along the tangent plane of the skin 5; in this embodiment, the plane of the fixing plate 12 is substantially parallel to the tangent plane of the skin 5, and tangential adjustment can be achieved by adjusting the position of the fixing plate 12 along the plane of the fixing plate 12. As shown in fig. 3 and 4, the fixing plate 12 is in a strip shape, and the fixing plate 12 can be displaced along the width direction by the tangential adjusting bolt 152 arranged along the width direction of the fixing plate 12, so as to realize tangential adjustment. Specifically, referring to fig. 9, the tangential adjusting bolt 152 is matched with the tangential adjusting screw hole 121 on the fixing plate 12, and when the tangential adjusting bolt 152 is rotated clockwise, the tangential adjusting bolt 152 can be screwed into the tangential adjusting screw hole 121, so that the distance between the fixing plate 12 and the mounting bracket 15 is shortened; and the mounting bracket 15 is fixed on the tool frame 2, so that the fixing plate 12 can move downwards. Conversely, when the tangential adjustment bolt 152 is rotated counterclockwise, the fixing plate 12 may be caused to move upward.
Optionally, a tangential screw limiting structure is further arranged on the fixing plate 12, and the tangential screw limiting structure is arranged on one side of the tangential adjusting screw hole 121 far away from the tool frame 2; referring to fig. 7 and 8, a tangential locking bolt 153 matched with the position of the tangential screw limiting structure is arranged on the mounting bracket 15, and the tangential locking bolt 153 is in threaded connection with the mounting bracket 15. Meanwhile, the tangential adjusting bolt 153 is in threaded connection with the tangential adjusting screw hole 121 through a light hole on the mounting bracket 15.
In the embodiment of the present invention, the tangential screw position-limiting structure is used to limit the position of the tangential locking bolt 153 during tangential adjustment. Specifically, the tangential screw limiting structure may be a groove, so that the position of the tangential locking bolt 153 may be limited, and the tangential locking bolt 153 is prevented from shaking left and right. In this embodiment, since the surface of the mounting bracket 15 is not a completely smooth surface, after the tangential locking bolt 153 abuts against the mounting bracket 15, the position of the tangential locking bolt 153 can be limited by using the friction force between the tangential locking bolt 153 and the mounting bracket 15, so as to prevent the tangential locking bolt 153 from shaking left and right.
Specifically, as shown in fig. 9, when the tangential adjusting bolt 152 is rotated clockwise, the distance between the fixing plate 12 and the mounting bracket 15 can be reduced, so that the fixing plate 12 can move downward; and when the tangential locking bolt 153 is rotated clockwise, the distance between the fixing plate 12 and the mounting bracket 15 can be increased so that the fixing plate 12 can be moved upward. When it is desired to move the fixing plate 12 upward, the tangential adjustment bolt 152 is rotated counterclockwise, so that the adjustable distance between the fixing plate 12 and the mounting bracket 15 is increased; since the tangential adjusting bolt 152 is in threaded connection with the tangential adjusting screw hole 121 through the unthreaded hole (i.e., the through hole with a smooth inner wall) of the mounting bracket 15, the position between the fixing plate 12 and the mounting bracket 15 is not fixed. In order to fix the fixing plate 12, the tangential locking bolt 153 is rotated clockwise, so that the tangential locking bolt 153 can be pressed against the fixing plate 12 (the tangential screw limiting structure on the fixing plate 12 can be pressed), so that the fixing plate 12 moves upwards, and after the position is determined, the two hexagon socket head cap bolts on the mounting bracket and the fixing plate are screwed, and the fixing plate 12 is locked. When the fixing plate 12 needs to be moved downwards, the tangential locking bolt 153 is rotated anticlockwise, so that the distance between the mounting bracket 15 and the fixing plate 12 is adjustable; then, the tangential adjusting bolt 152 is rotated clockwise, so that the distance between the fixing plate 12 and the mounting bracket 15 is reduced, and the fixing plate 12 can be tightly pressed under the action of the tangential locking bolt 153, so that the fixing plate 12 moves downwards, after the position is determined, the two hexagon socket head cap bolts on the mounting bracket and the fixing plate are screwed, and the fixing plate 12 is locked.
In this embodiment, the fixing plate 12 can be tangentially adjusted and fixed by using the tangential adjusting bolt 152 and the tangential locking bolt 153, so that the overall tangential position of the rotating component 1 can be adjusted, and the rotating component 1 can be more suitable for the positions of the stringers and the skin in the tangential direction. Meanwhile, referring to fig. 3, the left and right sides of the rotating component 1 are provided with mounting brackets 15, that is, the left and right sides of the rotating component 1 can be tangentially adjusted, which is not described in detail herein.
on the basis of the above embodiment, the tool structure can also realize the longitudinal adjustment of the rotating component. Similar to the tangential adjustment described above, the mounting bracket 15 is fixedly connected to the tool frame 2 through a kidney-shaped hole, so that the relative position between the mounting bracket 15 and the tool frame 2 is adjustable.
Referring to fig. 7 and 8, the mounting bracket 15 is provided with a longitudinal adjusting screw hole 151, and the longitudinal adjusting screw hole 151 is oriented along a normal of a plane where the fixing plate 12 is located; the tool frame 2 is provided with a longitudinal adjusting bolt 21 corresponding to the longitudinal adjusting screw hole 151. In the embodiment of the present invention, since the plane of the fixing plate 12 is parallel to the surface of the workpiece (such as the skin), the normal of the plane of the fixing plate 12 may be taken as the normal of the surface of the workpiece, and the "longitudinal adjustment" in the embodiment refers to an adjustment along the normal of the surface of the workpiece.
Referring to FIG. 10, the longitudinal adjustment bolt 21 mates with a longitudinal adjustment screw hole 151 on the mounting bracket 15; when the longitudinal adjustment bolt 21 is rotated clockwise, the longitudinal adjustment bolt 21 may be screwed into the longitudinal adjustment screw hole 151, so that the distance between the tool frame 2 and the mounting bracket 15 is shortened; since the tool frame 2 is fixed, the mounting bracket 15 can move in a direction close to the tool frame 2, i.e., downward in fig. 10. Conversely, when the longitudinal adjustment bolt 21 is rotated counterclockwise, the mounting bracket 15 may be caused to move upward.
Optionally, the mounting bracket 15 is further provided with a plurality of longitudinal screw limiting structures, the longitudinal screw limiting structures and the longitudinal adjusting screw holes 151 are arranged along the width direction of the fixing plate 12, and the plurality of longitudinal screw limiting structures are respectively arranged on two sides of the longitudinal adjusting screw holes 151. A longitudinal locking bolt 22 matched with the position of the longitudinal screw limiting structure is arranged on the tool frame 2, and the longitudinal locking bolt 22 is in threaded connection with the tool frame 2; the longitudinal adjusting bolt 21 is in threaded connection with the longitudinal adjusting screw hole 151 through a unthreaded hole in the tool frame 2.
In the embodiment of the present invention, the longitudinal screw limiting structure is similar to the tangential screw limiting structure, and may be a groove structure, or may be a part of the surface of the mounting bracket 15, which is not limited in this embodiment. The longitudinal adjusting screw hole 151 and the longitudinal screw limiting structure are arranged along the width direction of the fixing plate 12, and the corresponding longitudinal adjusting bolt 21 and the longitudinal locking bolt 22 are also arranged along the width direction of the fixing plate 12; because the fixing plate 12 is long and the fixing plate 12 is narrow in width, the arrangement of the longitudinal adjusting bolt 21 and the longitudinal locking bolt 22 can improve the stability during longitudinal adjustment.
Specifically, as shown in fig. 10, when the longitudinal adjusting bolt 21 is rotated clockwise, the distance between the mounting bracket 15 and the tool frame 2 can be reduced, so that the mounting bracket 15 can move upward; when the longitudinal locking bolt 22 is rotated clockwise, the distance between the mounting bracket 15 and the tool frame 2 can be increased, so that the mounting bracket 15 can move downward. When the mounting bracket 15 needs to be moved downwards, the longitudinal adjusting bolt 21 is rotated anticlockwise, so that the distance between the mounting bracket 15 and the tool frame 2 is increased; meanwhile, the longitudinal locking bolt 22 is rotated clockwise, so that the longitudinal locking bolt 22 can tightly push against the mounting bracket 15 (can tightly push against a longitudinal screw limiting structure on the mounting bracket 15), and the mounting bracket 15 can move downwards and be fixed in position. When the mounting bracket 15 needs to be moved upwards, the longitudinal locking bolt 22 is rotated anticlockwise, so that the distance between the tool frame 2 and the mounting bracket 15 is adjustable; then, the longitudinal adjusting bolt 21 is rotated clockwise, so that the distance between the mounting bracket 15 and the tool frame 2 is reduced, and the mounting bracket 15 can be tightly pressed under the action of the longitudinal locking bolt 22, so that the mounting bracket 15 moves upwards and is fixed in position.
In this embodiment, the longitudinal adjustment and fixation of the mounting bracket 15 can be achieved by the longitudinal adjustment bolt 21 and the longitudinal locking bolt 22, so that the overall longitudinal position of the rotating member 1 can be adjusted, and the rotating member 1 can be more adapted to the positions of the stringers and the skin in the longitudinal direction. Meanwhile, referring to fig. 3, the left and right sides of the rotating member 1 are provided with mounting brackets 15, that is, the left and right sides of the rotating member 1 can be longitudinally adjusted, which is not described in detail herein.
On the basis of the above embodiment, referring to fig. 2, the tooling structure further comprises a vacuum generating device 3. Referring to fig. 11, the vacuum generator 3 includes an oil-water separator 31, a vacuum generator 32, a mechanical valve 33, and a vacuum joint 34. One end of the vacuum generator 32 is connected with the oil-water separator 31, and the other end is connected with the vacuum joint 34 through the mechanical valve 33; the other end of the vacuum connection 34 is connected to the suction cup 14.
in the embodiment of the present invention, the vacuum generator 3 may be specifically configured as a box, components such as the oil-water separator 31 and the vacuum generator 32 are disposed in the box for protection, and the box door 36 may open the vacuum generator 3 to operate or inspect internal components. The vacuum generating device 3 mainly supplies vacuum negative pressure to the suction cup 14. The oil-water separator 31 separates oil from water in an external gas (such as a pumping gas) to remove impurities therein, and then sends the gas to the vacuum generator 32; the vacuum generator 32 generates a vacuum negative pressure and provides the vacuum negative pressure to the suction cup 14 through the vacuum connector 34. The mechanical valve 33 is a main switch of the vacuum generating device 3. Alternatively, the vacuum generating device 3 may be provided with a plurality of vacuum paths, illustrated as six paths in fig. 11, each path being provided with a corresponding finger valve 35 as a switch.
Specifically, after stringer 4 is attached to skin 5, mechanical valve 33 is opened, finger valve 35 connected to vacuum suction cup 14 is opened, and at this time, positive pressure flows into vacuum generator 32 to generate negative pressure, and suction cup 14 sucks skin 5. After the hole-making riveting operation is finished, the mechanical valve 33 can be closed to perform pressure relief operation, and the riveted workpiece is taken down from the tool structure.
according to the tool structure provided by the embodiment of the invention, the stringer is tightly propped by the ejector rod, and the skin is adsorbed by the sucker, so that opposite acting forces can be provided for the stringer and the skin, the stringer and the skin can be tightly attached, and the skin and the stringer are not easy to deform; the tool structure does not need to arrange a pressing plate outside the skin, the outer surface of the skin cannot be shielded, the sectional area of the ejector rod is small, and the contact area between the ejector rod and the stringer can be ignored, so that the tool structure hardly influences hole making, and the hole making coverage rate is improved; meanwhile, riveting work can be continuously carried out after the hole making operation is finished, the workpiece does not need to be structurally dismounted from the tool, and the hole making and riveting integrated tool can be realized. Furthermore, the rotating member 1 allows for longitudinal and tangential adjustment, so that the rotating member is more adaptable to the position of the stringers and skin in the longitudinal direction as well as in the tangential direction. The tool structure is also suitable for the hole making process of a robot, and can improve the hole making precision and the working efficiency.
