DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0035] See also Figure 1 The riveting machine includes a multi-axis pliers and shears riveting fixture seat 100, and a riveting work head 200 is correspondingly arranged above the multi-axis pliers and shears riveting fixture seat 100. In this embodiment, the riveting work head 200 is located above the center of the multi-axis pliers and shears riveting fixture seat 100. The riveting work head 200 is a prior art, and its specific structure and working principle are not repeated here. Taking the rotary riveting machine as an example, the operating center of the machine is formed by the rotation of the punch of the riveting work head 200. Its size and riveting effect usually determine that each time the riveting work head 200 is pressed down, it can complete the riveting of a rivet.

[0036] like Figure 2 and Figure 3As shown, a multi-axis pliers and shears tool riveting tool seat 100 comprises a tool base 110 and a clamping fixture 120 for fixing the pliers body 300 of the pliers and shears tool, the upper surface of the tool base 110 is a plane for placing the pliers body 300 for use with the riveting work head 200, and the upper surface of the tool base 110 is arranged with multiple groups of riveting group grooves with the same structure, each group of the riveting group grooves includes multiple riveting positioning grooves 111, and the number of groups of the riveting group grooves is the same as the number of the riveting positioning grooves 111 in each group of the riveting group grooves, and a riveting station groove 112 is provided on the tool base 110, and the riveting station groove 112 also serves as one of the riveting positioning grooves 111 in each group of the riveting group grooves, and the riveting station groove 112 corresponds to the riveting positioning grooves 111 at different positions in each group of the riveting group grooves. The riveting positioning groove 111 is used to pre-place rivets, and the relative positions of the holes of the pre-placed rivets are corrected to ensure that the relative positions of the remaining rivets do not shift when one rivet is riveted.

[0037] The riveting station slot 112 is located at the center of the tooling base 110. Figure 3 and Figure 6 This arrangement enables the riveting work head 200 to correspond to the riveting station slot 112 up and down, ensuring that the riveting work head 200 can complete the riveting of a rivet in the riveting station slot 112 each time it is pressed down.

[0038] See also Figure 3 and Figure 6 The upper surface of the tooling base 110 is also arranged with a plurality of fixing member mounting holes 113, each of the fixing member mounting holes 113 corresponds to a group of the riveting group grooves, that is, a group of the riveting group grooves corresponds to one fixing member mounting hole 113, and the clamping fixing member 120 is connected to the fixing member mounting hole 113 through a fixing bolt 121. The fixing member mounting hole 113 is a threaded hole with a relatively small aperture, which is used for threaded connection with the fixing bolt 121 to achieve the fixation of the clamping fixing member 120.

[0039] See also Figure 4 The clamping fixture 120 includes a vertical fixture 122, and horizontal clamping portions 123 are respectively provided on both sides of the vertical fixture 122. A vertical fixing hole 124 is formed through the vertical fixture 122. Figure 4 and Figure 5The two side surfaces of the vertical fixing member 122 are provided with V-shaped clamping parts 125 that are clamped with the pliers and scissors. The jaws of the pliers and scissors are provided with V-shaped clamping grooves 301 that are recessed inward. The V-shaped clamping parts 125 correspond to the V-shaped clamping grooves 301 to ensure that the jaws are fixed in the open state. When the pliers are placed on the corresponding riveting station on the tooling base 110, the jaws are opened and the vertical fixing member 122 is inserted from top to bottom, so that the horizontal clamping part 123 is against the upper plane of the jaws, and then the fixing bolt 121 is threadedly connected to the fixing member mounting hole 113 to ensure that the overall opening angle and position of the pliers are fixed, thereby ensuring the stability of the riveting of the pliers.

[0040] The diameter of each of the riveting positioning grooves 111 is the same as that of the riveting station grooves 112 , which is close to the head diameter of the maximum specification of the rivet head, so as to ensure the relative position accuracy of the installation and reduce the processing error caused by the shaking of multiple rivets during riveting.

[0041] Since the riveting station groove 112 is a structure that cooperates with the riveting work head 200 for riveting, when riveting, it is sufficient to ensure that the depth in the riveting station groove 112 can reach the required height for riveting. Here, the height of the riveting station groove 112 is used as a reference, and the depth of other riveting positioning grooves 111 can be the same as the depth of the riveting station groove 112, or it can be greater than the depth of the riveting station groove 112.

[0042] Embodiment 1:

[0043] by Fig.13 and Fig.14 Take the stacking pliers shown in the figure as an example. There are three rivets, which are arranged in a triangle. The rivets are countersunk solid metal rivets. The working principle is as follows:

[0044] The number of riveting positioning grooves 111 in the same group is the same as the number of rivet shafts of the pliers body 300 to be processed. In order to adapt to the riveting of the stacking pliers with three rivets, 7 large grooves and 3 small holes are provided on the surface of the tooling base 110, see Figure 6 , the large groove represents the riveting positioning groove 111, which does not penetrate the tooling base 110; the small hole represents the fixing installation hole 113, which may penetrate the tooling base 110 or not; the large groove located in the center is the riveting station groove 112, marked with X, which can also serve as the riveting positioning groove 111. The 7 large grooves form three groups of the riveting group grooves, namely (X, X1, X1), (X2, X, X2), and (X3, X3, X). The triangular arrangement formed by each group of the riveting group grooves is the same as the triangular arrangement of the three rivets of the stacking pliers, and the 3 small holes correspond to the three riveting group grooves one by one, namely x1, x2, and x3;

[0045] Since the stacking pliers include three rivets, to achieve the riveting of these three rivets, the position of the pliers needs to be moved. When the first rivet needs to be riveted, the main Figure 6 The three positions X, X1, and X1 correspond to the large slots and the x1 position corresponds to the small hole, that is, Figure 7 (a) The slot and hole corresponding to the connecting line position are the first riveting position of the stacking clamp; when the second rivet needs to be riveted, it is mainly used Figure 6 The three positions X2, X, and X2 correspond to the large slots and the x2 position corresponds to the small hole, that is, Figure 7 (b) The slot and hole corresponding to the connecting line position are the second riveting position of the stacking clamp; when the third rivet needs to be riveted, it is mainly used Figure 6 The three positions X3, X3, and X correspond to the large slots, and the x3 position corresponds to the small hole, that is, Figure 7 (c) The slot and hole corresponding to the position of the connecting line, that is, the third riveting position of the stacking clamp;

[0046] During riveting, the rivets are installed in sequence into the structural countersunk holes on one side of the stacking pliers, and then the rivet heads are placed downward into the grooves at the bottom of the tooling. The specifications of these rivets may be different, but through a unique design, the heights of these rivet countersunk heads exposed above the plane of the pliers body 300 are always consistent, so that when different rivet heads are placed into the riveting station slots 112 for riveting, the stress plane states of the rivets and the plane of the pliers body 300 in the vertical direction always remain approximately consistent; after the stacking pliers are placed in the riveting position, the clamping fixture 120 is connected to the corresponding fixture mounting hole 113 by means of fixing bolts 121 to fix the jaw opening angle state, and then the riveting work head 200 is pressed down to rivet the rivets in the riveting station slots 112. After one rivet is completed, it switches to the next riveting position to rivet the next rivet until all three rivets are riveted.

[0047] By uniquely designing the relative positions of the grooves and holes on the surface of the tooling base 110, the triangular riveting positions can be switched between the riveting group grooves, so that the riveting station grooves 112 can be replaced at will on the three riveting positions. Of course, the riveting order of the three riveting positions can be replaced in sequence according to actual operations.

[0048] The riveting positioning grooves 111 are used to pre-place rivets, and the pre-placed rivets are calibrated for relative hole positions to ensure that when one rivet is riveted, the relative positions of the remaining rivets are not offset.

[0049] The multi-axis clamp riveting process and the matching riveting fixture design can effectively solve the problems caused by multi-axis riveting of a single rivet, such as misalignment of rivet holes, insufficient relative hole position accuracy, inability to rivet remaining holes, riveting effect not as expected, and inability to quickly convert and adjust the riveting positions. The composite riveting process for the multi-axis clamp can simultaneously ensure the relative position accuracy of multiple riveting axes, riveting strength and expected riveting effect.

[0050] Embodiment 2:

[0051] The structure of the second embodiment is basically the same as that of the first embodiment. This embodiment adds more slots and holes on the basis of the first embodiment. Figure 8 and Fig. 9 The upper surface of the tooling base 110 is also provided with a plurality of reverse riveting grooves, which have the same structure as the riveting grooves and are bilaterally symmetrical with respect to the riveting station grooves 112. The upper surface of the tooling base 110 is also provided with a plurality of reverse fixing member mounting holes 113, each of which corresponds to a group of reverse riveting grooves, and the clamping fixing member 120 is connected to the reverse fixing member mounting hole 113 by a fixing bolt 121.

[0052] The reverse riveting group groove has the same structure as the riveting group groove and is bilaterally symmetrical about the riveting station groove 112 , so as to ensure reverse riveting of the pliers.

[0053] In this embodiment, 13 large grooves and 6 small holes are provided on the surface of the tooling base 110, see Figure 6 , the large groove represents the riveting positioning groove 111, the small hole represents the fixing installation hole 113, the large groove located in the center is the riveting station groove 112, marked with X, and can also serve as the riveting positioning groove 111. The 13 large grooves form a total of six groups of riveting group grooves, namely (X, X1, X1), (X2, X, X2), (X3, X3, X), (X, Y1, Y1), (Y2, X, Y2), (Y3, Y3, X), among which (X, X1, X1), (X2, X, X2), (X3, X3, X) are positive, and (X, Y 1, Y1), (Y2, X, Y2), (Y3, Y3, X) are in the reverse direction, and the forward and reverse directions are mirror-flipped; the 6 small holes are x1, x2, x3, y1, y2, y3, wherein x1, x2, x3 are used to correspond one-to-one with (X, X1, X1), (X2, X, X2), (X3, X3, X), respectively, and y1, y2, y3 are used to correspond one-to-one with (X, Y1, Y1), (Y2, X, Y2), (Y3, Y3, X), respectively; its specific working principle is basically the same as that of embodiment 1, and will not be repeated here.

[0054] Embodiment three:

[0055] The surface of the riveting head 200 is the surface that contacts the rivet to be riveted. When the working bottom surface area of ​​the riveting head 200 is large, see Fig.10 As shown, at this time, when the distance between the riveting working groove at the X position and the riveting positioning groove 111 at the adjacent X1 position is small, the riveting positioning groove 111 at the X1 position is within the working surface range of the riveting working head 200, which will cause secondary riveting extrusion to the rivet at the X1 position or damage the riveted head, affecting the riveting effect.

[0056] Therefore, the depth of the riveting positioning groove 111 adjacent to the riveting station groove 112 on the tooling base 110 is greater than the depth of the riveting station groove 112, that is, the depth of the riveting positioning groove 111 at the X1 position is deeper, and the rivet placed in the riveting positioning groove 111 at the X1 position will sink, and the exposed height of the rivet is lower than the rivet height of the riveting station groove 112 and is completely lower than the upper surface of the clamp body 300. When the riveting work head 200 presses down the rivet at the riveting work groove position, the riveting work head 200 only presses the rivet at the riveting work groove position to achieve a better riveting effect. When riveting the rivet at X1, because the depth of the riveting station groove 112 remains unchanged, the sunken rivet is lifted up by the riveting work groove, and can be riveted normally.

[0057] The riveting positioning groove 111 at the X position can be a groove with a relatively deep depth, or of course a through hole.

[0058] If the riveting machine has high precision and good performance, the riveting of a single rivet may not affect other rivets. In this case, the depths of the riveting station slot 112 and the riveting positioning slot 111 can be exactly the same. This embodiment can well solve the problems of interference between adjacent rivets, different riveting forces and heights when riveting a single rivet with multiple axes, and improve the riveting effect of multiple axes.

[0059] Embodiment 4:

[0060] When there are four rivets on the stacking clamp, the surface of the corresponding tooling base 110 is provided with 13 large grooves and 4 small holes, see Fig.12 The 13 large grooves form four groups of riveting grooves, namely (X, X1, X1, X1), (X2, X, X2, X2), (X3, X3, X, X3), (X4, X4, X4, X), and the triangular arrangement formed by each group of riveting grooves is the same as the triangular arrangement of the three rivets of the stacking pliers. The four small holes correspond to the four riveting grooves one by one, namely x1, x2, x3, and x4. The working principle of this embodiment is the same as that of the first embodiment, and the relative positions of the grooves and holes are uniquely designed on the surface of the tooling base 110.

[0061] The utility model reasonably plans and designs the grooves and holes of the tooling base 110, so that the riveting machine can be used not only for the riveting of single-axis pliers but also for the riveting of multi-axis pliers such as double-axis pliers, three-axis pliers, and four-axis pliers, and the equipment has a wider range of use.

[0062] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
