[0048] As a commonly used fixed connection method in mechanical processing, rivet connection has the advantages of low cost, high connection tightness, etc. In a riveting device with high automation degree, a driving device is usually arranged to push the rivet to a specified station, and the driving device is in abutment with a pressure applying device to rivet the rivet.

[0049] But using a set of driving equipment to drive rivet movement and to resist rivet riveting, so that in the riveting process, the driving equipment bears a large pressure, the driving equipment is easy to damage, and because the driving equipment bears a small load, the riveting effect is poor, and the rivet is easy to deflect or even fall off in the riveting process.

[0050] Based on the above idea and problem, the present application provides a pushing-out device 100 for pushing out the rivet 5, which converts the vertical movement into horizontal movement by cooperating the lifting assembly 3 with the inclined surface of the feeding block 2, so as to push out the rivet 5, and also uses the filling assembly 4 to abut against the feeding block 2, so that the feeding block 2 can avoid the impact of the impact force on the driving part when the riveting device 602 is riveting the rivet 5, effectively protecting the driving equipment from damage due to a large impact force during riveting, and effectively improving the riveting effect.

[0051] Please refer to Figures 1 to 6 In the embodiment of the present application, the pushing-out device 100 is used to push out the rivet 5, and the pushing-out device 100 comprises a shell 1, a feeding block 2 and a lifting assembly 3, the shell 1 is provided with a cavity 11 and a placing hole 12 communicating with the cavity 11, the placing hole 12 is used to place the rivet 5, the feeding block 2 is movably arranged in the cavity 11, and the feeding block 2 is provided with a top column 21 on the side facing the placing hole 12, the axis direction of the top column 21 coincides with the axis direction of the placing hole 12, and the top column 21 is used to push the rivet 5 placed in the placing hole 12, the feeding block 2 is provided with a first inclined surface 221 and a first vertical surface 23 on the side away from the top column 21, the lifting assembly 3 is installed on the shell 1, the lifting assembly 3 is provided with a first sliding block 31, at least part of the first sliding block 31 movably extends into the cavity 11 and is located on the side of the feeding block 2 away from the placing hole 12, and the first sliding block 31 is provided with a second inclined surface 311 and a second vertical surface 312; wherein the first sliding block 31 can slide in the direction perpendicular to the axis direction of the top column 21, so that the top column 21 has a first position away from the placing hole 12 and a second position close to the placing hole 12; when in the first position, the first inclined surface 221 and the second inclined surface 311 slide and abut against each other; when in the second position, the first vertical surface 23 and the second vertical surface 312 slide and abut against each other.

[0052] In the embodiment, as Figures 1 to 5As shown, the ejecting device 100 is provided with a housing 1 for supporting and placing the feeding block 2 and the jacking assembly 3, which can be a base, a mounting rack or a machine body 601, which is not limited herein. The housing 1 is internally formed with a containing cavity 11, in which the slidable feeding block 2 is placed. A placing hole 12 is formed in one side of the housing 1 and communicates with the containing cavity 11. A rivet 5 is placed in the placing hole 12. The feeding block 2 is provided with a jacking post 21 on the side facing the placing hole 12. The axis direction of the jacking post 21, the axis direction of the placing hole 12 and the axis direction of the rivet 5 coincide on a straight line. So that the jacking post 21 can push the rivet 5 placed in the placing hole 12 to move. It can be understood that the feeding block 2 can slide in the containing cavity 11 along the axis direction of the jacking post 21, so as to push the jacking post 21 to move in the direction of the placing hole 12 and push the rivet 5 in the placing hole 12 out of the placing hole 12.

[0053] In the embodiment, the jacking assembly 3 is installed on the housing 1. The jacking assembly 3 is provided with a first sliding block 31 which can slide on the housing 1 and partially extends into the containing cavity 11 and abuts against the side of the feeding block 2 away from the jacking post 21. The side of the feeding block 2 away from the jacking post 21 is formed with a first inclined surface 221 and a first vertical surface 23. The first inclined surface 221 and the first vertical surface 23 are two surfaces connected with each other. The first inclined surface 221 is adjacent to the jacking assembly 3, and the first vertical surface 23 is away from the jacking assembly 3. Meanwhile, the first sliding block 31 is provided with a second inclined surface 311 and a second vertical surface 312 which are connected with each other. The first inclined surface 221 is parallel to the second inclined surface 311, and the first vertical surface 23 is parallel to the second vertical surface 312 and both are in a vertical plane.

[0054] It can be understood that when the first sliding block 31 in the jacking assembly 3 moves in the direction of the feeding block 2, the second inclined surface 311 abuts against the first inclined surface 221. When the first sliding block 31 continues to move upward, the second inclined surface 311 and the first inclined surface 221 slide relative to each other. Under the action of the horizontal force of the second inclined surface 311, the feeding block 2 is pushed to move in the direction away from the placing hole 12. That is, the movement direction of the first sliding block 31 is perpendicular to the movement direction of the feeding block 2 to push the jacking post 21. The movement of the first sliding block 31 in the vertical direction is converted into the movement of the feeding block 2 in the horizontal direction. The driving mechanism for driving the first sliding block 31 does not directly drive the feeding block 2, so that the feeding block 2 can avoid bearing the riveting pressure when riveting.

[0055] In the embodiment, the top column 21 has a first position away from the placement hole 12 and a second position close to the placement hole 12; it can be understood that when in the first position, the first inclined surface 221 is in sliding abutment with the second inclined surface 311, at this time the top column 21 is arranged away from the placement hole 12; when converting from the first position to the second position, the first inclined surface 221 gradually separates from the sliding contact with the second inclined surface 311, and the top column 21 also gradually enters the placement hole 12, pushing the rivet 5 arranged in the placement hole 12 out of the placement hole 12, so that after the rivet 5 is completely pushed out, the first vertical surface 23 and the second vertical surface 312 begin to slide abutment, at this time the position between the feeding block 2 and the first sliding block 31 is relatively fixed, and the position between the top column 21 and the rivet 5 is also relatively fixed; when the external riveting device 602 rivets the rivet 5, the strong riveting force can be conducted to the feeding block 2 through the rivet 5 and the top column 21, and conducted to the first sliding block 31 through the first vertical surface 23 and the second vertical surface 312, and the whole forms a compact and solid pressure-bearing block to jointly act with the external riveting device 602 to complete riveting. In the prior art, only one set of equipment of the driving member is used to complete the pushing and abutting of the rivet 5, so that when cooperating with the external riveting device 602 for riveting, the driving member can only bear a smaller pressure, so that the riveting effect is poor, and even when the riveting force is larger, the driving member can be damaged. In the present application, the first sliding block 31 and the feeding block 2 are directly in sliding contact with the inclined surfaces, the vertical movement direction of the first sliding block 31 is converted into the horizontal movement direction of the feeding block 2, the riveting force of the external riveting device 602 is avoided from directly impacting the driving member, and the driving equipment is effectively protected.

[0056] The pushing device 100 is used for pushing and supporting the rivet 5. The pushing device 100 is provided with a shell 1, the shell 1 is formed with a cavity 11 for placing a feeding block 2, and a placing hole 12 for placing and conveying the rivet 5 is formed on the shell 1, the placing hole 12 is communicated with the cavity 11, so that the top column 21 provided on the feeding block 2 can push the rivet 5 along the axis direction of the placing hole 12. Meanwhile, the shell 1 is further provided with a jacking assembly 3 which is oppositely arranged with the placing hole 12, the jacking assembly 3 is provided with a first sliding block 31 which can slide on the shell 1, and the movement direction of the first sliding block 31 is perpendicular to the direction in which the top column 21 pushes the rivet 5; the side of the feeding block 2 which is away from the top column 21 is provided with a first inclined surface 221 and a first vertical surface 23, the first sliding block 31 is provided with a second inclined surface 311 which is parallel to the first inclined surface 221, and a second vertical surface 312 which is parallel to the first vertical surface 23, so that when the first sliding block 31 slides along the direction which is perpendicular to the axis direction of the placing hole 12, the first inclined surface 221 and the second inclined surface 311 slide and abut, and the first vertical surface 23 and the second vertical surface 312 slide and abut; when the first inclined surface 221 and the second inclined surface 311 slide and abut, the top column 21 has a first position which is away from the placing hole 12; when the first vertical surface 23 and the second vertical surface 312 slide and abut, the top column 21 has a second position which is close to the placing hole 12; when the top column 21 changes from the first position to the second position, the top column 21 can push the rivet 5 out of the placing hole 12, after the first inclined surface 221 and the second inclined surface 311 complete the sliding abutment, the first vertical surface 23 and the second vertical surface 312 slide and abut, so that when the rivet 5 is riveted and pressed, the feeding block 2 can abut the first sliding block 31 tightly, the riveting force of the rivet 5 on the feeding block 2 is transferred to the first sliding block 31, so that the driving part can not directly bear the riveting force, the driving equipment is protected, and the riveting effect is improved.

The first sliding block 31 is slidably mounted on the mounting plate 13, and the avoiding hole 14 is formed on the side of the shell 1 which is adjacent to the mounting plate 13 to avoid the first sliding block 31, so that the first sliding block 31 can partially extend into the cavity 11 to abut the feeding block 2.

[0059] It can be understood that the aperture of the avoiding hole 14 is slightly larger than the cross-sectional area of the first sliding block 31, so that the first sliding block 31 can pass through the avoiding hole and extend into the cavity 11. Meanwhile, the direction along the axis of the avoiding hole 14 is the same as the movement direction of the first sliding block 31, and is perpendicular to the movement direction of the feeding block 2. According to different actual working environments, the positions of the mounting plate 13 and the jacking assembly 3 can be adjusted, so that the movement direction of the first sliding block 31 can be kept perpendicular to the movement direction of the feeding block 2 in a horizontal plane, or in a vertical plane, or in a plane at any angle between the horizontal plane and the vertical plane, which is not limited herein.

[0060] In an embodiment, the jacking assembly 3 is further provided with a first driving member 32, which is arranged at the end of the mounting plate 13 away from the shell 1. The output end of the first driving member 32 is connected to the end of the first sliding block 31 away from the second inclined surface 311, and the output direction of the first driving member 32 is the same as the movement direction of the first sliding block 31.

[0061] In the embodiment, as shown in Figure 1 , Figures 3 to 5 The jacking assembly 3 is provided with the first driving member 32 at the end of the mounting plate 13 away from the shell 1, and the output end of the first driving member 32 faces the shell 1. The output end of the first driving member 32 is connected to the end of the first sliding block 31 away from the second inclined surface 311. It can be understood that the first driving member 32 is used to drive the first sliding block 31 to move along the direction along the axis of the avoiding hole 14, that is, to push the first sliding block 31 to move to the side of the feeding block 2, and to push the feeding block 2 to move along the direction along the axis of the placing hole 12 through the sliding cooperation of the first inclined surface 221 and the second inclined surface 311, so as to push out the rivet 5 arranged in the placing hole 12.

A protruding portion 24 is formed between the two inclined grooves 22, and the side of the protruding portion 24 opposite to the top post 21 is flush with the first vertical surface 23. In the first position, the protruding portion 24 can slide along the sliding groove 313 when the first inclined surface 221 and the second inclined surface 311 abut.

[0068] In this embodiment, as shown in Figure 4 and Figure 5 , the two inclined grooves 22 are formed on the two sides of the feeding block 2, and the two sides are perpendicular to the surface on the side where the top post 21 is arranged. The two inclined grooves 22 are open grooves, and a first inclined surface 221 is formed on each inclined groove 22. A protruding portion 24 is formed between the two inclined grooves 22, and the side of the protruding portion 24 opposite to the top post 21 is also a vertical surface, and the vertical surface of the protruding portion 24 is flush with the first vertical surface 23. It can be understood that the first sliding block 31 is provided with an inclined block corresponding to the inclined groove 22, and the inclined block is arranged on both sides of the sliding groove 313 and cooperates with the inclined groove 22 in the first position. The second inclined surface 311 is arranged on the inclined block.

[0069] It can be understood that the inclined block is arranged on the end of the second sliding block 41 facing the feeding block 2 and is in sliding cooperation with the inclined groove 22 in the feeding block 2. The protruding portion 24 between the two inclined grooves 22 also cooperates with the sliding groove 313 between the two inclined blocks. The first sliding block 31 and the protruding portion 24 form a close sliding cooperation connection, so that in the first position, the first inclined surface 221 and the second inclined surface 311 are in sliding cooperation, and in the second position, the first vertical surface 23 and the second vertical surface 312 are in sliding cooperation. The arrangement of the inclined groove 22 and the protruding portion 24 improves the accuracy of inclined surface transmission when the first sliding block 31 and the feeding block 2 slide relative to each other, and avoids deviation and disengagement of transmission.

[0070] In an embodiment, the shell 1 is provided with two rotating shafts adjacent to the placement hole 12, and the two rotating shafts are arranged in the vertical direction. A limiting plate 15 is movably arranged on each rotating shaft, and the two limiting plates 15 are arranged on the horizontal sides of the placement hole 12, respectively. Each limiting plate 15 is elastically connected to the shell 1. Each limiting plate 15 is provided with a semicircular groove adjacent to one end of the placement hole 12. The two semicircular grooves form a through groove 151, which is in communication with the placement hole 12, so that the rivet 5 can pass through the through groove 151 and enter the placement hole 12, and one end of the rivet 5 is placed in the through groove 151.

[0071] In this embodiment, as shown in Figures 1 to 4As shown, the shell 1 is provided with two rotatable limiting plates 15 on the surface of the side where the placement hole 12 is opened. The limiting plates 15 are rotated through the rotating shafts arranged on both sides of the placement hole 12 in the vertical direction. One end of the limiting plate 15 is arranged adjacent to the opening of the placement hole 12, and the other end is elastically connected with the shell 1. Each limiting plate 15 is provided with a semicircular groove at one end adjacent to the opening of the placement hole 12. The two semicircular grooves form a through groove 151. The axis direction of the through groove 151 coincides with the axis direction of the placement hole 12, and the through groove 151 is communicated with the placement hole 12. The diameter of the through groove 151 is smaller than the diameter of the placement hole 12.

[0072] As can be understood, the rivet 5 has a head end and a column end. When the rivet 5 passes through the limiting plates 15 arranged on both sides of the placement hole 12 from the head end, the head pushes the limiting plates 15 to rotate to the side of the placement hole 12. When the head enters the placement hole 12, the limiting plates 15 on both sides rebound to the side away from the placement hole 12 under the elastic force of the elastic connection with the shell 1, so that the column is just positioned in the through groove 151. Since the diameter of the through groove 151 is smaller than the diameter of the placement hole 12, and the diameter of the through groove 151 is slightly larger than the diameter of the column, the column is limited and placed in the through groove 151, and the column of the rivet 5 is in a horizontal state. When the second driving member 42 pushes the tubular rivet 5 out of the placement hole 12, the head can also push the limiting plates 15 to rotate to the side away from the placement hole 12, so that the rivet 5 can be completely taken out of the positioning assembly. The arrangement of the limiting plates 15 not only realizes the bidirectional entry and exit of the rivet 5 through the elastic connection of the limiting plates 15 with the shell 1, but also realizes the horizontal limiting and placement of the rivet 5 through the through groove 151, so as to ensure that the rivet 5 always moves along the axis direction when entering and exiting, improve the movement accuracy, and avoid deviation.

[0073] In an embodiment, the number of placement holes 12 is 1 to 10, and the number of top columns 21 corresponds to the same number of placement holes 12. As can be understood, the number of placement holes 12 is 1 to 10, which can be 1, 2, 4, 5, or 8, which is not limited here. Correspondingly, the number of top columns 21 is the same as the number of placement holes 12, so that the feeding block 2 can move to push the multiple rivets 5 arranged in the multiple placement holes 12 to move to meet the different riveting needs of different products, and improve the universality and applicability of the pushing-out device 100. Optionally, one end of the top column 21 facing the limiting plate 15 is provided with a circular arc groove 211 for positioning the rivet 5. As can be understood, the circular arc groove 211 is used for positioning and fixing the rivet 5. When the rivet 5 enters the pushing-out device 100, the column of the rivet 5 can be limited and placed through the through groove 151, and the head of the rivet 5 can be limited and placed through the circular arc groove 211; when the rivet 5 is pushed out, the circular arc groove 211 can also ensure that the rivet 5 moves along the axis direction to avoid the rivet 5 from deviating and not accurately reaching the riveting station.

[0074] The present invention also proposes a riveting device 600, such as... Figure 6 As shown, the riveting equipment 600 includes a body 601, the aforementioned ejection device 100, and a riveting pressing device 602. A positioning block 6011 is provided on the body 601. The ejection device 100 is installed around the positioning block 6011. The riveting pressing device 602 is installed on the body 601 relative to the ejection device 100 and is used to cooperate with the ejection device 100 to rivet the rivet 5. The specific structure of the ejection device 100 is as described in the foregoing embodiments. Since this riveting equipment 600 adopts all the technical solutions of all the foregoing embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated upon here.

[0075] In one embodiment, multiple ejection devices 100 are provided, and all of the multiple ejection devices 100 are installed around the periphery of the positioning block 6011 and are arranged in a ring-shaped symmetrical manner. It can be understood that... Figure 6 As shown, multiple ejection devices 100 can be provided, and all of the multiple ejection devices 100 are installed around the periphery of the positioning block 6011. In one embodiment, the positioning block 6011 provided in the riveting device 600 can be replaced with different sizes to adapt to different products. The cross-sectional shape of the positioning block 6011 can be polygonal, or it can be a circle or ellipse with curvature, and is not limited here. Preferably, in order to facilitate the installation of the ejection device 100 on the positioning block 6011, the positioning block 6011 is selected as polygonal, so that each ejection device 100 can be installed on the edge of a polygon of the positioning block 6011, thereby improving the connection tightness between the ejection device 100 and the positioning block 6011, and at the same time facilitating the installation and removal of the ejection device 100. The ends of the multiple ejection devices 100 away from the positioning block 6011 together form an abutment surface, which abuts against the product, so that the multiple ejection devices 100 together abut against the product on one side. While pressing the product, the ejector 100 also passes the placed rivet 5 through the hole to be riveted on the product and presses against the rivet 5. Together with the riveting device 602, it squeezes the rivet 5 to deform it, thereby riveting the product. Compared with the prior art, the ejector 100 can rivet multiple parts of the workpiece at the same time, and can also press against the rivet 5 while conveying it, effectively improving riveting efficiency and enhancing the integration and miniaturization of the equipment.
