Description

Technical Field

[0001] The utility model belongs to the technical field of riveting tooling, in particular to a universal riveting tooling. Background Art

[0002] Riveting is a method of connecting two or more workpieces by using fasteners such as rivets or rivets between them. Riveting is often used in structures that require high-strength connections or work in high-temperature environments. During the riveting process, the rivet passes through the workpiece to be connected through a pre-drilled hole, and then locks the workpieces together by forming a head at the riveted joint. Riveting technology is widely used in the connection of two structures. This process has high connection strength and good tightness, which makes the structure effectively resist stress and fatigue and is more durable. In the production of aviation products, a large number of rivets are needed. In order to ensure the quality and reliability of riveting, rivets need to be subjected to riveting tests. By conducting riveting tests, the strength, durability and stability of the riveted connection can be evaluated to ensure that it meets the design requirements and safety standards.

[0003] Conventional riveting tests use a multi-hole fixture for rivets with a length of more than 2.2d. This fixture can only test the shank of flat or countersunk rivets after filing the head, and the length of the specimen after filing must be no less than 2.2d. This places higher requirements on the filing process of the riveted specimen, and uneven filing can easily lead to the end size after upsetting not meeting the requirements. For rivets with a length of ≤2.2d, another quenched steel plate hole fixture is used. Rivets with different diameters and different nail rod lengths require hole fixtures of different specifications for testing, which increases the demand for fixtures in the early stage of the test and increases the test cost. After the test, it is also necessary to measure whether the sample size is within the qualified range. The test process is cumbersome and cannot improve efficiency.

[0004] A riveting tool is disclosed in the patent with publication number CN219188383U. This design uses a cylinder to push a positioning block to position a riveting connecting rod inserted on the positioning block. In addition to reducing the labor intensity, it can also ensure the accuracy of the position of the riveting connecting rod, thereby increasing the quality of subsequent riveting. However, since this design uses a fixed placement hole to fix the rivet, it has a poor versatility and cannot be applied to rivets of different sizes. Utility Model Content

[0028] The mounting slot 109 has two side walls near the top thereof, and the two card boards 104 are symmetrically connected to the card slots 108. The two card boards 104 are symmetrically arranged with the card slots 108. The two card boards 104 are arranged with corresponding card interfaces 103 on the sides close to each other. The bottom plate 110 is arranged below the card boards 104.

[0029] The mounting body 101 is provided with a first adjustment hole 114, which is in communication with the card slot 108, and a first adjustment rod 106 is connected to the adjustment hole through a thread, and the end of the first adjustment rod 106 is connected to the card plate 104; specifically, the first adjustment rod 106 is in contact with or rotationally connected to the card plate 104, and the card plate 104 is moved by rotating the first adjustment rod 106. The bottom of the mounting body 101 is provided with a second adjustment hole 116, which is in communication with the mounting slot 109, and a second adjustment rod 115 is connected to the second adjustment hole 116 through a thread, and the end of the second adjustment rod 115 is connected to the bottom plate 110. Specifically, the second adjustment rod 115 is in contact with or rotationally connected to the card plate 104, and the end of the second adjustment rod 115 is connected to the bottom plate 110. Specifically, the second adjustment rod 115 is in contact with or rotationally connected to the card plate 104, and the end of the second adjustment rod 115 is moved by rotating the second adjustment rod 115.

[0030] Specifically, when using, Figure 1 As shown, the riveting tool 1 is placed under the riveting press 2 for use. First, by rotating the first adjusting rod 106 and allowing the clamping plates 104 on both sides to open each other, the head of the rivet is placed flat on the top surface of the bottom plate 110, and the light rod of the rivet is passed through the space between the clamping interfaces 103.
