Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft assembly riveting, and particularly relates to a process device for riveting. Background Art

[0002] Due to the influence of its special structure and part fold angles of the aircraft (such as the fixed part skeleton of the vertical tail), blind rivets are often required for riveting. Riveting is a process method in which the shank of the rivet in the rivet hole of the part is upset axially to form a head so as to connect multiple parts. The most common riveting method is hammer riveting. Hammer riveting uses the piston of the riveting gun to impact the riveting chuck, and the riveting chuck pushes the workpiece with the rivet to vibrate. At the other end of the rivet, it is held by a backing bar, so that the shank of the rivet is upset to form a head. However, when riveting, it is easy for the riveting gun to be non-perpendicular, resulting in a unilateral gap in the rivet. At this time, the rivet needs to be removed and riveted again. This process is likely to cause the hole diameter to exceed the tolerance, damage the processed parts, and reduce the riveting strength if riveted multiple times. Therefore, a relatively high skill level of workers is required. At present, the riveting of blind rivets still depends to a large extent on the operation level of workers. Content of the Utility Model

[0003] To solve the above technical defects, the technical problem to be solved by the utility model is to provide a process device for riveting, which can ensure the perpendicularity of the riveting gun and the riveting chuck to the part during the riveting process using blind rivets, and reduce the occurrence of unilateral gaps in the rivets.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: A process device for riveting, including a riveting gun and a riveting chuck, and the riveting chuck is connected to the riveting gun; the process device for riveting further includes:

[0005] A fixing component, the fixing component is sleeved outside the riveting chuck, its front end is detachably connected to the riveting gun, and the rear end is slidably connected to a sliding component;

[0006] A sliding component, the sliding component is sleeved outside the riveting chuck perpendicular to the surface of the processed part, its front end is sleeved inside the fixing component, and the rear end is attached to the processed part;

[0007] An elastic component, the elastic component is sleeved inside the fixing component and provides a restoring force for the sliding component to slide inside the fixing component.

[0008] Further, the riveting chuck is located inside the cavity structure formed by the connection of the fixing component, the sliding component and the elastic component.

[0009] Further, the fixing component includes a housing; a stepped hole is provided inside the front end of the housing, and a sliding groove is provided inside the rear end; the elastic component is located between the stepped hole and the sliding groove.

[0010] Further, the head of the riveting gun is provided with an external thread; the stepped hole is an internal thread hole, and the stepped hole is connected to the external thread of the riveting gun through the internal thread hole.

[0011] Further, the sliding member is composed of an inner core and a rubber pad; the inner core is located at the front end of the sliding member for connecting the fixing member; the rubber pad is located at the rear end of the sliding member for fitting the surface of the part; the inner core and the rubber pad are fixed by gluing.

[0015] The utility model adopts the above technical solutions, and the beneficial effects obtained are as follows:

[0016] During the riveting process of the convex head rivet, in addition to using the riveting gun and the riveting chuck for riveting, a process device composed of a fixing member, a sliding member and an elastic member is newly added. The fixing member is sleeved on the riveting gun, and the elastic member supports the front end cover of the sliding member, providing a restoring force for the sliding member to move back and forth in the sliding groove of the fixing member. The rear end of the sliding member fits the surface of the processed part. When the riveting chuck contacts the rivet for riveting, the rear end cover of the sliding member is directly positioned on the surface of the processed part, ensuring the perpendicularity of the riveting gun and the riveting chuck relative to the processed part, reducing the occurrence of unilateral clearance, and improving the riveting quality and efficiency of the operator.

[0024] The following specific embodiments illustrate the implementation modes of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1-2 shown, the present invention provides a process device for riveting, including a riveting gun 1, a riveting chuck 2, a fixing component 3, a sliding component 4 and an elastic component 5.

[0026] As Figure 3 shown, the fixing component 3 is a cylindrical barrel, including an outer shell 31; a stepped hole 31a is provided in the front-end barrel of the outer shell 31, and the stepped hole 31a is an internal thread hole for externally threaded connection with the head of the riveting gun 1, and its end face is used for placing the elastic component 5; a sliding groove 31b is provided in the rear-end barrel of the outer shell 31.

[0027] As Figure 4 shown, the sliding component 4 is a cylindrical barrel, perpendicular to the surface of the processed part, and is composed of an inner core 41 and a hard plastic rubber pad 42. The inner core 41 is sleeved in the outer shell 31, and a protrusion 41a is provided on its outer circle. The protrusion 41a is used for sliding in the sliding groove 31b, so that the inner core 41 can slide in the outer shell 31; the hard plastic rubber pad 42 is fixedly glued to the inner core 41, and its rear-end cover is used for fitting the processed part.

[0028] As Figure 5 shown, the elastic component 5 is an annular spring, sleeved in the fixing component, located in the middle of the stepped hole 31a and the sliding groove 31b, supporting the front-end cover of the inner core 41, and providing a restoring force for the inner core 41 to slide in the outer shell 31.

[0029] The riveting chuck 2 is fixed on the riveting gun 1 and is located in the cavity structure jointly formed by the connection of the fixing component 3, the sliding component 4 and the elastic component 5, and is used for hitting the rivet.

[0030] The utility model adopts a quick-release structure. When in use, first place the elastic component 5 into the fixed component 3, then fit the fixed component 3 and the sliding component 4 together, then put the required riveting clamp 2 into the riveting gun 1, and finally fit the fixed component 3 onto the riveting gun 1 through the threaded hole to complete the installation of the riveting process device. Before riveting, under the action of the elastic component 5, the connected fixed component 3 and the sliding component 4 are pressed. The protrusion 41a of the sliding component 4 moves towards the surface of the part in the sliding groove 31b of the fixed component 3 under the push of the elastic component 5, so that the hard plastic gasket 42 in the sliding component 4 closely adheres to the surface of the processed part, making the riveting gun 1 and the riveting clamp 2 perpendicular to the surface of the part. The riveting clamp 2 acts on the rivet to ensure that the rivet vertically enters the rivet hole of the part, thereby completing the riveting. The utility model has a simple structure, is convenient to install and operate, ensures that the operator holds the riveting gun perpendicular to the processed part when using it, and improves the processing quality and efficiency. It can be applicable to the riveting work of various riveting clamps and various types of rivets.
