Description

Technical Field

[0001] This utility model relates to the field of wing clamping technology, and in particular to a flexible clamping device with a cut edge. Background Technology

[0002] The wing is one of the most important components of an aircraft structure, and its design and manufacturing process have a decisive impact on the overall performance and safety of the aircraft. During the wing manufacturing process, wing clamping devices are typically used to hold the wing in place to ensure stability and precise positioning.

[0003] Currently, to facilitate clamping wings of different shapes, the shape of the clamps is usually designed based on the shape characteristics of the wings. When there are multiple shapes of wings to be processed, and the processing is a small-batch production task, each shape of wing requires a corresponding special clamp, which not only increases the production and manufacturing cost, but also leads to low utilization of the clamps. Utility Model Content

[0004] In order to improve the utilization rate of wing clamps and reduce the manufacturing cost of wing production, this application provides a flexible clamping device for cutting edges.

[0005] The flexible clamping device for edge trimming provided in this application adopts the following technical solution: A flexible clamping device for cutting edges includes a support base with several through holes. A telescopic rod is inserted into each through hole and slidably connected to the support base. A mounting seat is provided on one end of each telescopic rod. An installation assembly is provided on the side wall of the mounting seat to fix adjacent mounting seats. An abutment is fixedly provided on the other end of each telescopic rod. A telescopic spring is sleeved on the telescopic rod, with one end of the spring abutting against the support base and the other end abutting against the abutment.

[0006] By adopting the above technical solution, several clamping devices are connected by mounting components according to the size of the workpiece to be clamped, thereby forming a set of clamping fixtures adapted to the size of the workpiece to be clamped. After the clamping fixtures are assembled, the workpiece to be clamped is placed between the clamping fixtures, with the abutments all facing the workpiece. Then, the clamping fixtures are moved closer to the workpiece. When the abutments contact and press the workpiece, they move closer to the support seat and press the telescopic spring. The elastic force generated by the telescopic spring applies a clamping force to the workpiece. The support surface formed by the abutments undulates with the surface shape of the workpiece, conforming to the shape of the clamping surface. This reduces the need for special fixtures for each shape of wing, improves the utilization rate of wing fixtures, and reduces the manufacturing cost of wing production.

The first plug is fixedly mounted on the left side wall of the mounting base, and the first socket is fixedly mounted on the right side wall of the mounting base. A first slot is formed through the first socket on the side away from the mounting base, and the first slot is for inserting the first plug. The first plug and the first socket are detachably connected.

[0008] By adopting the above technical solution, when connecting adjacent mounting bases laterally, the first plug on one mounting base is inserted into the first slot of the adjacent mounting base, and then the first plug is connected to the first socket to achieve the effect of connecting adjacent mounting bases laterally.

[0009] Preferably, a plurality of first mounting grooves are formed through the side wall of the first socket, and the first mounting grooves are interconnected with the first slot. A plurality of first mounting holes are formed through the first plug, and a first mounting screw is inserted into the first mounting holes and the first mounting grooves. A set of first mounting nuts are threaded onto the first mounting screw, and the opposite face of the first mounting nuts is used to abut against the side wall of the first socket.

[0010] By adopting the above technical solution, when the first plug on one of the mounting bases is inserted into the first slot of the adjacent mounting base, the first mounting hole and the first mounting groove are set opposite to each other. Then, the first mounting screw passes through the first mounting hole and the first mounting groove, and then the first mounting nut is screwed into the first mounting screw so that the opposite surface of the first mounting nut abuts against the side wall of the first socket.

[0011] Preferably, the mounting assembly includes a second plug and a second socket. The second plug is fixedly mounted on the bottom wall of the mounting base, and the second socket is fixedly mounted on the top wall of the mounting base. A second slot is formed through the second socket on the side away from the mounting base, and the second slot is for inserting the second plug. Adjacent second plugs and second sockets are detachably connected.

[0012] By adopting the above technical solution, when connecting adjacent mounting bases longitudinally, the second plug on one mounting base is inserted into the second slot of the adjacent mounting base, and then the second plug is connected to the second socket to achieve the effect of longitudinal connection of adjacent mounting bases.

[0013] Preferably, a plurality of second mounting grooves are formed through the side wall of the second socket, and the second mounting grooves are connected to the second slot. A plurality of second mounting holes are formed through the second plug, and a second mounting screw is inserted into the second mounting hole and the second mounting groove. A set of second mounting nuts are threaded onto the second mounting screw, and the opposite face of the second mounting nuts is used to abut against the side wall of the second socket.

[0014] By adopting the above technical solution, when the second plug on one of the mounting bases is inserted into the second slot of the adjacent mounting base, the second mounting hole and the second mounting groove are set opposite to each other. Then, the second mounting screw passes through the second mounting hole and the second mounting groove, and then the second mounting nut is screwed into the second mounting screw so that the opposite surface of the second mounting nut abuts against the side wall of the second socket.

[0015] Preferably, the telescopic rod has a threaded groove on its outer wall, and an adjusting nut is fitted onto the telescopic rod. The adjusting nut cooperates with the threaded groove and is threadedly connected to the telescopic rod. One end of the telescopic spring is fixedly connected to the support base, and the other end of the telescopic spring is fixedly connected to the adjusting nut.

[0016] By adopting the above technical solution, when the adjusting nut is rotated, the adjusting nut moves with the telescopic rod. By changing the position of the adjusting nut, the force applied by the telescopic spring to the abutment is adjusted.

[0017] Preferably, a guide sleeve is fitted onto the telescopic rod, the telescopic rod and the guide sleeve are slidably connected, one end of the guide sleeve is fixedly connected to the mounting base, and the other end of the guide sleeve is fixedly connected to the support base.

[0018] By adopting the above technical solution, when the telescopic rod slides in the support through hole, the telescopic rod moves along the guide sleeve, and the guide sleeve guides the telescopic rod, reducing the tilting of the telescopic rod.

[0019] Preferably, a limiting ring groove is formed on the inner wall of the guide sleeve, and a limiting ring plate is slidably arranged in the limiting ring groove. The side wall of the limiting ring plate is in contact with the inner wall of the limiting ring groove, and the limiting ring plate is fixedly connected to the end of the telescopic rod away from the abutment.

By setting the first plug, the first socket, and the first slot, the effect of lateral connection between adjacent mounting bases is achieved; 3. By setting a second plug, a second socket, and a second slot, the effect of longitudinal connection between adjacent mounting bases can be achieved. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a flexible clamping device for cutting edges. (Refer to...) Figure 1The system includes a support base 1 with several through holes 11. Telescopic rods 2 are inserted into the through holes 11 and are slidably connected to the support base 1. A mounting seat 3 is mounted on one end of each telescopic rod 2, and an abutment 5 is mounted on the other end. Mounting components 4 are provided on the side walls of the mounting seats 3 to fix adjacent mounting seats 3. Telescopic springs 21 are fitted onto the telescopic rods 2, with one end abutting against the support base 1 and the other end abutting against the abutment 5. Several clamping devices are connected via the mounting components 4 according to the size of the workpiece to be clamped, thus forming a set of clamping fixtures adapted to the size of the workpiece. After the clamping fixtures are assembled, the workpiece to be clamped is placed between the clamping fixtures, with all abutments 5 facing the workpiece. Then, the clamping fixture is brought closer to the workpiece to be clamped. When the abutment 5 contacts and presses against the workpiece, the abutment 5 moves closer to the support base 1 and presses against the telescopic spring 21. The elastic force generated by the telescopic spring 21 applies a clamping force to the workpiece. The support surface formed by the abutment 5 follows the undulating shape of the workpiece surface, conforming to the shape of the workpiece. This reduces the need for dedicated fixtures for each type of wing, improves the utilization rate of wing fixtures, and reduces the manufacturing cost of wing production.

[0030] Reference Figures 1 to 4 The mounting component 4 includes a first plug 41, a first socket 42, a second plug 43, and a second socket 44. The first plug 41 is welded to the left side wall of the mounting base 3, the first socket 42 is welded to the right side wall of the mounting base 3, the second plug 43 is welded to the bottom wall of the mounting base 3, and the second socket 44 is welded to the top wall of the mounting base 3.

[0031] Reference Figures 1 to 4 A first socket 42 has a first slot 421 extending through its side away from the mounting base 3, for inserting a first plug 41. Several first mounting grooves 62 extend through the side wall of the first socket 42, communicating with the first slot 421. Several first mounting holes 63 extend through the first plug 41, and a first mounting screw 6 is inserted into both the opposing first mounting holes 63 and the first mounting grooves 62. A set of first mounting nuts 61 are threaded onto the first mounting screw 6. When connecting adjacent mounting bases 3 laterally, the first plug 41 of one mounting base 3 is first inserted into the first slot 421 of the adjacent mounting base 3, so that the first mounting hole 63 and the first mounting groove 62 are opposite each other. Then, the first mounting screw 6 extends through the first mounting hole 63 and the first mounting groove 62, and then the first mounting nuts 61 are screwed into the first mounting screw 6, so that the opposing surfaces of the first mounting nuts 61 abut against the side wall of the first socket 42, achieving the effect of connecting adjacent mounting bases 3 laterally.

[0032] Reference Figures 1 to 4A second socket 44 has a second slot 441 extending through its side away from the mounting base 3, for inserting a second plug 43. Several second mounting grooves 72 extend through the side wall of the second socket 44, communicating with the second slot 441. Several second mounting holes 73 extend through the second plug 43, and a second mounting screw 7 is inserted into both the opposing second mounting holes 73 and the second mounting grooves 72. A set of second mounting nuts 71 are threaded onto the second mounting screw 7. When longitudinally connecting adjacent mounting bases 3, the second plug 43 of one mounting base 3 is first inserted into the second slot 441 of the adjacent mounting base 3, so that the second mounting hole 73 and the second mounting groove 72 are opposite each other. Then, the second mounting screw 7 extends through the second mounting hole 73 and the second mounting groove 72, and then the second mounting nuts 71 are screwed into the second mounting screw 7, so that the opposing surfaces of the second mounting nuts 71 abut against the side wall of the second socket 44, achieving the effect of longitudinally connecting adjacent mounting bases 3.

[0033] Reference Figure 1 and Figure 5 A threaded groove 81 is formed on the outer wall of the telescopic rod 2. An adjusting nut 8, which mates with the threaded groove 81, is fitted onto the telescopic rod 2, and the adjusting nut 8 is threadedly connected to the telescopic rod 2. When the adjusting nut 8 is rotated, it moves with the telescopic rod 2. One end of the telescopic spring 21 is welded to the support base 1, and the other end is welded to the adjusting nut 8. By changing the position of the adjusting nut 8, the force exerted by the telescopic spring 21 on the abutment joint 5 is adjusted.

[0034] Reference Figure 1 A guide sleeve 9 is fitted onto the telescopic rod 2, and the telescopic rod 2 is slidably connected to the guide sleeve 9. One end of the guide sleeve 9 is welded to the mounting base 3, and the other end of the guide sleeve 9 is welded to the support base 1. When the telescopic rod 2 slides within the support through hole 11, the telescopic rod 2 moves along the guide sleeve 9. The guide sleeve 9 guides the telescopic rod 2, reducing the skewness of the telescopic rod 2 and improving the stability of the sliding of the telescopic rod 2.

[0035] Reference Figure 1 A limiting annular groove 91 is formed on the inner wall of the guide sleeve 9. A limiting annular plate 92 is slidably disposed within the limiting annular groove 91. The side wall of the limiting annular plate 92 is in contact with the inner wall of the limiting annular groove 91. The limiting annular plate 92 is welded to the end of the telescopic rod 2 away from the abutment 5. When the telescopic rod 2 moves along the guide sleeve 9, the telescopic rod 2 drives the limiting annular plate 92 to move along the inner wall of the limiting annular groove 91. The telescopic rod 2 is not easily dislodged from the guide sleeve 9 due to the restriction of the limiting annular plate 92.

[0036] The implementation principle of the flexible clamping device for edge trimming in this application embodiment is as follows: Based on the size of the workpiece to be clamped, several mounting seats 3 on the clamping devices are connected to form a set of clamping fixtures adapted to the size of the workpiece. After the clamping fixtures are assembled, the workpiece to be clamped is placed between the clamping fixtures, with all abutment joints 5 facing the workpiece. Then, the clamping fixtures are moved closer to the workpiece. When the abutment joints 5 contact and press against the workpiece, they move closer to the support seat 1 and press against the telescopic spring 21. The elastic force generated by the telescopic spring 21 applies a clamping force to the workpiece. The support surface formed by the abutment joints 5 undulates with the surface shape of the workpiece, conforming to the shape of the workpiece, reducing the need for dedicated fixtures for each type of wing, improving the utilization rate of wing fixtures, and reducing wing manufacturing costs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
