Description

Technical Field

[0001] The invention relates to the field of riveting process training, and in particular to a training platform for efficiently training riveting workers to use jacking irons. Background Art

[0002] In the field of aircraft manufacturing, the fuselage surface is composed of a large number of skins. Among the composite materials used for aircraft skins, most are aluminum alloys and carbon fiber metals. The biggest feature of aluminum alloys is that they are light and thin, with a thickness of only 2-3 mm. Among all mechanical connection methods, the biggest advantage of riveting is that it is suitable for thin-wall connections. At the same time, riveting also has the advantages of simple process, vibration resistance, reliable connection, and impact resistance.

[0003] In the aircraft assembly process, according to different application conditions, riveting methods can be roughly divided into automatic drilling and riveting and manual riveting. With the development of industrial automation, automatic drilling and riveting technology has gradually matured, but for areas with limited space, riveted assembly surfaces with gradual changes, and areas with more complex surfaces, such as the head and tail of the aircraft, manual riveting is still required to complete the assembly production work. In the riveting process, the consistency of the riveting quality will have a great impact on the riveting quality of the overall working conditions. For manual riveting, the worker's operating skills largely determine the quality of the hand-hammer riveted joints, but due to the uneven operating skills of the workers, the joint quality varies greatly, and consistency is difficult to guarantee.

[0004] With the continuous development of domestic large aircraft research and development, the demand for riveting skilled personnel is also increasing. However, the current training method for skilled workers is still the traditional training method, that is, training through two riveting workers. This training method is inefficient and costly, and the training requires two people to cooperate, resulting in poor flexibility. At the same time, the current training method focuses more on rivet gun training. Equipment has been developed that riveting workers can use to train rivet guns alone, but there is no professional training equipment for top iron training. How to enable riveting workers to conduct high-efficiency, high-flexibility, and low-cost top iron training has become a problem. Summary of the invention

[0005] In order to solve the technical problems existing in the prior art, the present invention provides a training platform for efficiently training riveting workers to use top irons, which can more efficiently, flexibly and effectively train riveting workers to use top irons during riveting training to improve the quality of manual riveted joints.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A training platform for efficiently training riveting workers to use top irons comprises a base, a cylinder bracket, a guide rod cylinder, a cylinder connecting piece, a sliding guide rail, a rivet gun clamping mechanism and a riveting plate clamping mechanism, wherein the cylinder bracket is fixed to one side of the base, the guide rod cylinder is fixed to the top of the cylinder bracket, the cylinder connecting piece is fixed to the front of the guide rod cylinder, the sliding guide rail is fixed to the base, and the lower ends of the rivet gun clamping mechanism and the riveting plate clamping mechanism are slidably connected to the sliding guide rail.

[0008] As a preferred technical solution, the rivet gun clamping mechanism includes a rivet gun, a slider, a V-block and a rivet gun clamping base. The slider is slidably connected to the sliding guide rail, the lower part of the rivet gun clamping base is fixedly connected to the slider by screws, and the V-block is connected to the top of the rivet gun clamping base by screws to clamp the rivet gun between the V-shaped notch of the V-block and the rivet gun clamping base.

[0009] As a preferred technical solution, a first groove is provided on the lower surface of the sliding block, the bottom surface of the first groove contacts the upper surface of the sliding guide rail, and the two sides of the first groove are clearance-matched with the two sides of the sliding guide rail.

[0010] As a preferred technical solution, the training platform also includes a pneumatic control system, which includes a first electrical proportional valve and a second electrical proportional valve. The first electrical proportional valve controls the working air pressure of the rivet gun, and the second electrical proportional valve changes the tightening force of the rivet gun by controlling the input air pressure of the guide rod cylinder.

[0011] As a preferred technical solution, the riveted plate clamping mechanism includes a moving block, a riveted plate clamping base, a riveted plate and multiple pressure plates. The moving block is slidably connected to the sliding guide rail, the riveted plate clamping base is fixed to the moving block by screws, and the pressure plate is connected to the upper side of the riveted plate clamping base by screws to clamp the riveted plate between the pressure plate and the riveted plate clamping base, and the rear end of the rivet gun is perpendicular to the front end face of the cylinder bracket.

[0012] As a preferred technical solution, the riveted plate is an aluminum plate with countersunk holes.

[0013] As a preferred technical solution, a second groove is provided on the lower surface of the moving block, the bottom surface of the second groove contacts the upper surface of the sliding guide rail, and both sides of the second groove are clearance-matched with both sides of the sliding guide rail.

[0014] As an optimal technical solution, two cap-type hexagonal nuts are provided on the base, and the two cap-type hexagonal nuts are symmetrically installed on both sides of the sliding guide rail. The cap-type hexagonal nuts are fixed to the base by screws, and the distance between the two cap-type hexagonal nuts does not exceed the width of the riveted plate clamping mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention uses a guide rod cylinder to replace the worker holding the rivet gun to apply the tightening force, thereby reducing the cost of training the riveting workers to push the iron and improving the flexibility of training to push the iron;

[0017] (2) The present invention controls the input rivet gun air pressure and time through an electrical proportional valve and a solenoid valve, and controls the input guide rod cylinder air pressure, time and contraction direction through an electrical proportional valve and a steering valve, so that the process parameters can be easily adjusted and the coverage range is wide;

[0018] (3) The present invention can simulate the characteristics of various working conditions of manual riveting by controlling the curve and time of input air pressure with the help of an electric proportional valve;

[0019] (4) The present invention forms a sliding mode by adding a slider under the riveting plate clamping mechanism, thereby ensuring that the force applied by the rivet gun end and the top iron end is absorbed by the riveting plate, simulating the real riveting profile environment to the greatest extent, and having strong practical significance;

[0020] (5) The present invention can accurately control various riveting parameters by inputting parameters through a touch screen, achieve repeatability of multiple trainings, and ensure consistency of training effects. BRIEF DESCRIPTION OF THE DRAWINGS
