Description

Technical Field

[0001] The utility model relates to the technical field of aerospace mechanical component assembly, in particular to a wing handle clamping device. Background Art

[0002] In the aerospace field, clamping devices are required for high-precision processing, assembly and testing of precision mechanical parts. However, with the continuous development of aerospace technology, the complexity and precision requirements of mechanical parts are increasing, and traditional clamping methods can no longer meet the needs of current aerospace engineering. Most traditional clamping devices use rigid structures, which makes it difficult to adapt to mechanical parts of different shapes, materials and sizes, and the clamping accuracy and stability are limited. When clamping the wing handle, since the wing handle is composed of multiple plates, and there is a certain gap between adjacent plates, the width of the plates is also changing. The traditional clamping device cannot achieve stable clamping of the wing handle, resulting in a decrease in assembly accuracy, affecting the overall safety of aerospace engineering.

[0003] In order to overcome the above-mentioned clamping problem, the utility model proposes a wing handle clamping device that fits the wing handle. Utility Model Content

[0004] The utility model aims to provide a wing handle clamping device which is suitable for clamping wing handles of various structures and improves the clamping stability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wing handle clamping device comprises a frame and a clamping jaw assembly, wherein the clamping jaw assemblies are symmetrically arranged on both sides of the frame, a plurality of mounting grooves are opened at the bottom of the frame, a two-way hydraulic cylinder is fixedly arranged in the mounting groove, the telescopic ends at both ends of the two-way hydraulic cylinder are hinged with connecting pieces, the clamping jaw assembly comprises four groups of clamping jaws, each group of clamping jaws comprises four identical clamping jaws, two rotating shafts are arranged at the bottom of the frame, the rotating shafts are fixedly connected to the frame through mounting plates at both ends, one end of the top of the clamping jaw is rotatably connected to the rotating shaft, the other end of the top of the clamping jaw is hinged with the connecting piece, a clamping plate is fixedly arranged at the bottom of the clamping jaw, and a rubber plate is fixedly arranged on the side of the clamping plate away from the clamping jaw.

[0007] As a preferred technical solution, the lengths of the four groups of clamping jaws increase sequentially.

[0008] As a preferred technical solution, the two clamping jaws on the same side of each group of clamping jaws are fixedly connected to the same clamping plate, and the four clamping plates are arranged in sequence from top to bottom.

[0009] As a preferred technical solution, the rubber plate is fixedly connected to four clamping plates.

[0010] As a preferred technical solution, a plurality of grooves are horizontally provided on one side of the rubber plate away from the clamping plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, four groups of clamping claws are provided, which can better fit the shapes of both sides of the wing handle during clamping, and can be adjusted according to the structure of the wing handle. It is suitable for clamping wing handles of various shapes and structures, and the clamping stability is high.

[0013] 2. In the utility model, a whole rubber plate is used to fix the four clamping plates, so as to avoid the wing handle being stuck in two adjacent clamping plates during clamping, which affects the clamping effect. Moreover, the rubber plate can fit the wing handle more closely, thereby improving the stability of clamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example

[0024] like Figure 1-3 As shown, a wing handle clamping device includes a frame 1 and a clamping claw assembly. The clamping claw assembly is symmetrically arranged on both sides of the frame 1. A plurality of mounting grooves 2 are provided at the bottom of the frame 1. A two-way hydraulic cylinder 3 is fixedly arranged in the mounting groove 2. The telescopic ends of both ends of the two-way hydraulic cylinder 3 are hinged with connecting parts 4. The clamping claw assembly includes four groups of clamping claws 5. Each group of clamping claws 5 includes four identical clamping claws 5, wherein two clamping claws 5 are respectively provided on the left and right sides. The two left and right clamping claws 5 corresponding to each other constitute a pair of clamping claws 5. Each two-way hydraulic cylinder 3 is used to control a pair of clamping claws 5.

[0025] Two rotating shafts 7 are provided at the bottom of the frame 1, and the rotating shaft 7 is fixedly connected to the frame 1 through mounting plates 6 at both ends. One end of the top of the clamping jaw 5 is rotatably connected to the rotating shaft 7, and the other end of the top of the clamping jaw 5 is hinged to the connecting piece 4. A clamping plate 8 is fixedly provided at the bottom of the clamping jaw 5, and a rubber plate 9 is fixedly provided on the side of the clamping plate 8 away from the clamping jaw 5.

[0026] It is worth mentioning that the frame 1 is provided to provide an installation position for the clamping device, and is also used to connect the clamping device to an external robotic arm or an assembly device. The clamping operation of the wing handle is realized by the provided clamping claw assembly, the opening and closing of the clamping claw 5 is controlled by the provided bidirectional hydraulic cylinder 3, the clamping operation is realized by the provided rubber plate 9 being fitted with the wing handle, and the rubber plate 9 and the clamping claw 5 are connected by the provided clamping plate 8, and the force of the clamping claw 5 is transmitted to the rubber plate 9 to clamp the wing handle.

[0027] In some feasible embodiments, the lengths of the four groups of jaws 5 increase sequentially, the two jaws 5 on the same side of each group of jaws 5 are fixedly connected to the same clamping plate 8, and the four clamping plates 8 are arranged sequentially from top to bottom, so that each clamping plate 8 is controlled by two jaws 5, thereby increasing the clamping force of the clamping plate 8.

[0028] Furthermore, the distances between the two pairs of clamping jaws 5 in each group of clamping jaws 5 are the same.

[0029] In some feasible embodiments, the rubber sheet 9 is fixedly connected to the four clamping plates 8. The flexible rubber sheet 9 is fixedly connected to the four clamping plates 8, and each clamping plate 8 controls the rubber sheet 9 in a certain area, so that when the wing handle is clamped, the rubber sheet 9 can change according to the shape of the wing handle, which is controlled by the opening angle of the clamping jaws 5, so that the rubber sheet 9 fits the shape of the wing handle better and the clamping stability is higher.

[0030] In some feasible embodiments, a plurality of grooves are horizontally provided on one side of the rubber plate 9 away from the clamping plate 8, thereby increasing the contact area and friction between the rubber plate 9 and the wing handle, and making the clamping more stable.
