[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0058] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] The embodiment of the present application provides a method for compensating the gap in the assembly of a riveted assembly. The riveted assembly includes a first component to be riveted 10 and a second component to be riveted 20. The first component to be riveted 10 and the second component to be riveted 20 are both long and small riveted components. The first component to be riveted 10 and the second component to be riveted 20 are riveted together by a riveting piece 60 after being pressed.

[0060] According to actual assembly requirements, the first component to be riveted 10 is an upper riveted component, and the second component to be riveted 20 is a lower riveted component.

[0061] like Figure 1 As shown, the riveting assembly gap compensation method includes:

[0062] S1: machining a base hole 30 on a first component to be riveted 10;

[0063] S2: Pressing the first component to be riveted 10 and the second component to be riveted 20 according to a preset pressing requirement to ensure that the riveting position gap between the first component to be riveted 10 and the second component to be riveted 20 is within a preset range;

[0064] S3: After the first component to be riveted 10 and the second component to be riveted 20 are separated, the adhesive 40 is applied to the first component to be riveted 10 and the second component to be riveted 20 according to the riveting position gap;

[0065] S4: Compressing the first component to be riveted 10 and the second component to be riveted 20 according to the preset pressing requirement, and determining whether the adhesive 40 fills the base hole 30;

[0066] If the adhesive 40 fills the base hole 30, the adhesive 40 is cured to complete the compensation of the gap at the riveting position.

[0067] If the adhesive 40 does not fill up the base hole 30 , the adhesive is injected through the base hole 30 for compensation, and the adhesive 40 is cured to complete the compensation of the gap at the riveting position.

[0068] In S1, Figure 2 As shown, according to the rivet arrangement requirements of the design drawing, the riveting positioning base hole 30 is prefabricated when the first to-be-riveted component 10 is processed, and the aperture range of the base hole 30 is controlled within 0.7-0.9D (D is the aperture of the riveting hole 50 or the target aperture), that is, the aperture ratio of the riveting hole to the base hole is 1:0.7 to 1:0.9. The base hole 30 plays the role of assembly positioning, gap measurement, glue injection compensation and rapid drilling.

[0069] In S2, the first component to be riveted 10 and the second component to be riveted 20 are pre-assembled and matched on the tooling, and are positioned and pressed according to the process requirements. It should be noted that the riveting position gap between the first component to be riveted 10 and the second component to be riveted 20 needs to be maintained within a preset range, which is 0-1 mm.

[0070] In S3, the preassembled first component to be riveted 10 and the second component to be riveted 20 are separated and opened again by a hanger to leave an operating space for subsequent gluing. After that, adhesive 40 (or structural adhesive, such as EP6250) is applied on the contact surfaces of the first component to be riveted 10 and the second component to be riveted 20.

[0071] like Figure 4 As shown, the thickness h of the structural adhesive is above 1 mm, and the width of the structural adhesive covers the corresponding contact surface.

[0072] In S4, after the adhesive coating is completed, the first component to be riveted 10 and the second component to be riveted 20 are closed within the operable time of the adhesive 40, and the pressing operation is performed according to the pressing requirements adjusted after pre-assembly. Considering that the adhesive 40 has a certain fluidity during the pressing and closing process of the first component to be riveted 10 and the second component to be riveted 20, the adhesive 40 flows around and gradually fills the base hole 30 (such as Figure 5 As shown in FIG. 1 ), even in the area with a smaller gap, the excess adhesive 40 overflows through the base hole 30 (as shown in FIG. Figure 6 as shown).

[0073] The above method can fill the uneven inter-plate gap between the entire first component to be riveted 10 and the second component to be riveted 20 .

[0074] In addition, after the first component 10 to be riveted and the second component 20 to be riveted are closed, the filling of the glue at the riveting position is observed through the base hole 30, so that the compensation quality of the adhesive 40 can be quickly detected; if the adhesive 40 does not fill the base hole 30 (such as Figure 7 As shown, the glue injection compensation is performed through the base hole 30 (as shown Figure 8 As shown in the figure), since the adhesive 40 has a certain fluidity, it can automatically squeeze into the unfilled gap through the base hole 30 to compensate for the situation where the gap at some riveting positions has not been completely eliminated.

[0075] The beneficial effects of the riveting assembly gap compensation method set in this way mainly include:

[0076] First, by machining the base hole 30 on the first component to be riveted 10, not only can the assembly positioning, gap measurement and drilling and hole making functions of the first component to be riveted 10 and the second component to be riveted 20 be realized, but also when the adhesive 40 does not fill the base hole 30, the adhesive can be injected through the base hole 30 to compensate for the gap at the riveting position. Therefore, the base hole 30 solves the problems of difficult positioning, gap measurement, gap compensation and drilling and positioning in the assembly process of the riveted assembly;

[0077] Secondly, by using an adhesive 40 with high fluidity, the irregular small gap between the riveted positions of the first component 10 to be riveted and the second component 20 to be riveted is compensated, and the problem of difficulty in eliminating the irregular small gap is solved. In addition, the combination of the adhesive 40 and the rivet 60 realizes the composite connection of the riveted joint, which significantly improves the strength of the entire joint and solves the problem of insufficient sealing performance of the purely mechanical riveted connection. In addition, the adhesive 40 can also play a role in potential isolation for the contact of heterogeneous materials (such as the connection between carbon fiber and steel parts), thereby reducing the risk of corrosion.

[0078] In some embodiments, before the step of pressing the first component to be riveted 10 and the second component to be riveted 20 according to a preset pressing requirement to ensure that the riveting position gap between the first component to be riveted 10 and the second component to be riveted 20 is within a preset range, the step includes:

[0079] Pre-assemble, fit, position and press the first component 10 and the second component 20 to be riveted together;

[0080] After the riveting position gap is maintained within the preset range with the preset clamping requirement, record the preset clamping requirement.

[0081] The first component to be riveted 10 and the second component to be riveted 20 are pre-assembled and matched on the tooling, and are positioned and pressed according to the process requirements. At the same time, the riveting position gap between the first component to be riveted 10 and the second component to be riveted 20 needs to be maintained within a preset range according to the preset pressing requirements, and the preset range is 0-1mm.

[0082] In some embodiments, after the steps of pre-assembling, matching, positioning and pressing the first component to be riveted 10 and the second component to be riveted 20, the following steps are further included:

[0083] The gap between the first component 10 to be riveted and the second component 20 to be riveted is adjusted.

[0084] Specifically, the step of adjusting the gap between the first component to be riveted 10 and the second component to be riveted 20 includes:

[0085] The distance between the upper surface of the first component to be riveted 10 and the upper surface of the second component to be riveted 20 is measured through the base hole 30, and the riveting position gap is obtained;

[0086] Determine whether the riveting position gap is within the preset range;

[0087] If the gap at the riveting position is not within the preset range, adjust the clamping point and clamping force according to the gap at the riveting position to achieve the preset clamping requirements.

[0088] It should be noted that the riveting position gap (G) between the first component to be riveted 10 and the second component to be riveted 20 is measured by using the base hole 30 on the first component to be riveted 10, specifically including first measuring the depth (Dp) through the base hole 30, or the distance between the upper surface of the first component to be riveted 10 and the upper surface of the second component to be riveted 20, and then calculating the difference between the depth (Dp) and the plate thickness (t1) of the first component to be riveted 10, to obtain the riveting position gap (i.e., G=Dp-t1), as shown in FIG. Figure 3 After that, the clamping point and the clamping force are adjusted according to the measurement results, specifically by judging whether the riveting position gap is within the preset range. If the riveting position gap is not within the preset range, the clamping point and the clamping force are adjusted according to the riveting position gap to meet the preset clamping requirements and ensure that the riveting position gap is controlled within 1 mm. If the riveting position gap is within the preset range, S3 is executed.

[0089] For the measurement of the gap at the riveting position, in addition to using a measuring ruler to extend into the base hole 30, a gap measurement module and a control module can also be provided. The gap measurement module includes a metal sheet provided with a strain gauge. The gap measurement module is provided between the first component to be riveted 10 and the second component to be riveted 20, and is used to extend into the gap at the riveting position during measurement; the control module is used to receive the strain value measured by the strain gauge, and convert the strain value into a gap value according to the corresponding relationship between the preset strain value and the gap at the riveting position.

[0090] Furthermore, the gap value can be further fitted with data to obtain the three-dimensional morphology of the gap at the riveting position, and then the three-dimensional morphology of the gap at the riveting position can be sliced ​​at predetermined intervals, and the amount of adhesive 40 for subsequent compensation can be linearly adjusted according to the area of ​​each slice and the amount of adhesive 40 applied.

[0091] In some embodiments, the step of applying the adhesive 40 to the first component to be riveted 10 and the second component to be riveted 20 according to the riveting position gap is specifically as follows:

[0092] Structural adhesive is applied on the contact surfaces of the first component to be riveted 10 and the second component to be riveted 20 . The thickness of the structural adhesive is above 1 mm, and the width of the structural adhesive covers the corresponding contact surfaces.

[0093] After the glue coating is completed, the first component to be riveted 10 and the second component to be riveted 20 are closed within the operable time of the adhesive 40, and the pressing operation is performed according to the pressing requirements adjusted after pre-assembly.

[0094] In some embodiments, if the adhesive 40 fills the base hole 30, the adhesive 40 is cured to complete the step of compensating the gap at the riveting position, and if the adhesive 40 does not fill the base hole 30, the adhesive is injected through the base hole 30 for compensation, and the adhesive 40 is cured to complete the step of compensating the gap at the riveting position, both of which further include:

[0095] Processing the riveting hole 50 according to the position of the base hole 30;

[0096] The rivet member 60 is inserted into the rivet hole 50 for riveting.

[0097] For the curing of the adhesive 40, first remove the excess adhesive 40 (such as Fig. 9 As shown), after the adhesive 40 is completely cured, the first component 10 to be riveted and the second component 20 to be riveted are bonded together by the adhesive 40 and have a certain strength, thereby completely eliminating the gap between the plates.

[0098] For the processing of the rivet hole 50, the rivet hole 50 is prepared by drilling the base hole 30 according to the hole making requirements of the drawing, such as Fig.10As shown, at this time, the excess adhesive 40 and the drilling cuttings of the upper and lower riveted components are removed in the form of powder, and finally the required riveting hole 50 is formed.

[0099] In some embodiments, the step of inserting the rivet 60 into the rivet hole 50 for riveting includes:

[0100] Measuring the clamping thickness of riveted components;

[0101] Determine whether the clamping thickness meets the clamping range requirement of the current riveted part 60;

[0102] If the clamping thickness meets the clamping range requirement of the current rivet 60, the rivet 60 is inserted into the rivet hole 50 for riveting;

[0103] If the clamping thickness does not meet the clamping range requirement of the current rivet 60 , a suitable rivet 60 is replaced according to the clamping thickness and inserted into the rivet hole 50 for riveting.

[0104] Of course, the riveting member 60 may be a rivet.

[0105] That is to say, for inserting rivets, first, measure the clamping thickness of the riveted assembly, and then determine whether the clamping thickness meets the requirements of the designed rivet clamping range (i.e., determine whether the rivet clamping length L≥t1+t2+G is established, where t1 is the plate thickness of the first component to be riveted 10, t2 is the plate thickness of the second component to be riveted 20, and G is the riveting position gap between the first component to be riveted 10 and the second component to be riveted 20). If the rivet clamping length L≥t1+t2+G is established, insert the rivet directly into the rivet hole for riveting. If the rivet clamping length L≥t1+t2+G is not established, replace the rivet with a suitable length according to the clamping thickness and insert it into the rivet hole to complete the riveting. Fig.11 shown.

[0107] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0108] The above is a detailed introduction to the assembly gap compensation method of the riveted assembly and the riveted assembly provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the scheme of the present application and its core idea.
