[0072] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0073] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0074] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0075] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0076] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0077] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0078] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0079] Figure 1 This is a structural schematic diagram of a riveting device according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a riveting device according to one embodiment of the present disclosure from another angle.
[0080] like Figure 1 and Figure 2 As shown, the riveting device disclosed herein may include components such as a seat assembly 100, an upper riveting head 200, a lower riveting head 300, and a drive device 400.
[0081] The seat assembly 100 disclosed herein may include components such as a base plate 110, a support frame 120, and a housing 130, wherein the support frame 120 is disposed on the base plate 110 and can support components such as a drive device 400. Specifically, the drive device 400 may be a motor, which can be fixed on the support frame 120.
[0082] The housing 130 is disposed on the base plate 110, wherein components such as the upper riveting head 200 and the lower riveting head 300 can be located outside the housing 130, and components such as the first transmission assembly 700 and the second transmission assembly 800 described below can be disposed inside the housing 130.
[0083] In one embodiment, a guide rail 140 is provided on one outer wall of the housing 130; wherein the guide rail 140 is arranged substantially vertically. An upper slider 150 and a lower slider are slidably provided on the guide rail 140.
[0084] Both the upper riveting head 200 and the lower riveting head 300 are slidably mounted on the base assembly 100; specifically, the upper riveting head 200 is mounted on the upper slider 150 via the upper adjustment mechanism 500. The lower riveting head 300 is mounted on the lower slider via the lower adjustment mechanism 600.
[0085] Figure 3 This is a schematic diagram of the upper adjustment mechanism according to one embodiment of the present disclosure.
[0086] like Figure 3 As shown, the position of the upper riveting head 200 can be adjusted in two directions through the upper adjustment mechanism 500. Specifically, the upper adjustment mechanism 500 includes components such as an upper base plate 510, a first upper adjustment seat 520, a second upper adjustment seat 530, a first upper sliding seat 540, a first upper adjustment screw 550, a second upper adjustment screw 560, a third upper adjustment seat 570, and a third upper adjustment screw 580.
[0087] The upper substrate 510 is fixed to the upper slider 150; specifically, the guide rail 140 of this disclosure can be set to two, and the two guide rails 140 are arranged in parallel. Each guide rail 140 can be provided with two upper sliders 150, in which case the upper substrate 510 is fixed to four upper sliders 150.
[0088] The first upper adjustment seat 520 and the second upper adjustment seat 530 are both disposed on the upper base plate 510; specifically, the first upper adjustment seat 520 and the second upper adjustment seat 530 are both vertically disposed, and at this time, there is a preset interval between the first upper adjustment seat 520 and the second upper adjustment seat 530.
[0089] The first upper sliding seat 540 is disposed between the first upper adjusting seat 520 and the second upper adjusting seat 530, and the position of the first upper sliding seat 540 can be adjusted in the horizontal direction. Specifically, the first upper adjusting seat 520 is provided with a first upper adjusting screw 550, and the second upper adjusting seat 530 is provided with a second upper adjusting screw 560. Thus, the position of the first upper sliding seat 540 in the horizontal direction can be adjusted by the first upper adjusting screw 550 and the second upper adjusting screw 560. After the position of the first upper sliding seat 540 is adjusted, the first upper sliding seat 540 is fixed to the upper base plate 510.
[0090] In this disclosure, a guide groove is provided on the first upper sliding seat 540, and the upper riveting head 200 is slidably disposed within the guide groove of the first upper sliding seat 540. The position of the upper riveting head 200 is restricted by the side wall of the guide groove, so that the position of the upper riveting head 200 in the horizontal direction is restricted. In other words, the guide groove of this disclosure is set approximately vertically, so the upper riveting head 200 cannot move in the horizontal direction, but can only move in the vertical direction.
[0091] The third upper adjustment seat 570 is disposed on the upper substrate 510, and specifically, the third upper adjustment seat 570 is disposed approximately horizontally. A third upper adjustment screw 580 is disposed on the third upper adjustment seat 570, thereby allowing adjustment of the vertical position of the upper riveting head 200. After the position of the upper riveting head 200 is adjusted, the upper riveting head 200 is fixed to the upper substrate 510.
[0092] Figure 4 This is a schematic diagram of the structure of the lower adjustment mechanism according to one embodiment of the present disclosure.
[0093] like Figure 3 and Figure 4 As shown, the vertical position of the lower riveting head 300 can be adjusted by the lower adjustment mechanism 600. Specifically, the lower adjustment mechanism 600 includes components such as a lower base plate 610, a first lower adjustment seat 620, a second lower adjustment seat 630, a first lower seat component 640, a first lower adjustment screw 650, a second lower adjustment screw 660, a first wedge block 670, and a second wedge block 680.
[0094] The lower substrate 610 is fixed to the lower slider; specifically, the guide rails 140 of this disclosure can be configured as two, and these two guide rails 140 are arranged in parallel. Each guide rail 140 can be provided with two lower sliders, in which case the lower substrate 610 is fixed to four lower sliders.
[0095] The first lower adjustment seat 620 and the second lower adjustment seat 630 are both disposed on the lower base plate 610; specifically, the first lower adjustment seat 620 and the second lower adjustment seat 630 are both vertically disposed, and there is a preset interval between the first lower adjustment seat 620 and the second lower adjustment seat 630.
[0096] The first lower seat component 640 is disposed between the first lower adjusting seat 620 and the second lower adjusting seat 630, and is fixed to the lower base plate 610. Furthermore, the first lower seat component 640 has a vertical guide groove and a horizontal guide groove. The riveting head 300 is slidably disposed within the vertical guide groove of the first lower seat component 640, and the position of the riveting head 300 is restricted by the sidewall of the vertical guide groove, thereby restricting the horizontal position of the riveting head 300. In other words, the vertical guide groove of this disclosure is set approximately vertically, in which case the riveting head 300 cannot move in the horizontal direction, but can only move in the vertical direction.
[0097] Furthermore, a first wedge block 670 is provided in the vertical guide groove of the first lower seat component 640. The first wedge block 670 includes a wedge-shaped surface (lower surface) and a plane (upper surface) opposite to the wedge-shaped surface. That is, the lower surface of the first wedge block 670 is a wedge-shaped surface, and the upper surface of the first wedge block 670 is a plane. The upper surface of the first wedge block 670 can contact the lower end of the lower riveting head 300, so that the first wedge block 670 can drive the lower riveting head 300 to produce a lifting and lowering movement.
[0098] The second wedge block 680 is slidably disposed in the horizontal guide groove of the first lower seat component 640. The upper surface of the second wedge block 680 is a wedge-shaped surface, and the upper surface of the second wedge block 680 can cooperate with the lower surface of the first wedge block 670. Thus, when the second wedge block 680 moves horizontally, the first wedge block 670 can be made to move up and down.
[0099] The first lower adjustment seat 620 is provided with a first lower adjustment screw 650, and the second lower adjustment seat 630 is provided with a second lower adjustment screw 660. Thus, the position of the second wedge block 680 in the horizontal direction can be adjusted by the first lower adjustment screw 650 and the second lower adjustment screw 660, thereby adjusting the position of the lower riveting head 300 in the vertical direction.
[0100] Figure 5 This is a schematic diagram of the transmission assembly of a riveting device according to one embodiment of the present disclosure. Figure 6 and Figure 7 This is a structural schematic diagram of the transmission assembly of a riveting device according to one embodiment of the present disclosure at different angles.
[0101] like Figures 5 to 7As shown, the drive device 400 of this disclosure is used to simultaneously drive the upper riveting head 200 and the lower riveting head 300 to move, so that the upper riveting head 200 and the lower riveting head 300 can approach or move away from each other.
[0102] Specifically, the drive device 400 drives the upper slider 150 to slide through the first transmission component 700, and the drive device 400 drives the lower slider to slide through the second transmission component 800.
[0103] In a preferred embodiment, the first transmission component 700 and the second transmission component 800 have the same structure.
[0104] Specifically, the first transmission assembly 700 includes components such as a first cam 710, a first lever 720, and a first connecting rod 730.
[0105] The drive unit 400 is used to drive the first cam 710 to rotate; wherein the drive shaft of the drive unit 400 extends into the interior of the housing 130, the first cam 710 is located inside the housing 130 and is mounted on the drive shaft.
[0106] A first follower 740 is provided at one end of the first lever 720, and the first follower 740 is used to engage with the first cam 710; wherein, the middle part of the first lever 720 is rotatably connected to the seat assembly 100 through a hinge shaft; specifically, the middle part of the first lever 720 is hinged to the first lever seat, and the first lever seat can be fixed to the housing of the seat assembly 100.
[0107] One end of the first connecting rod 730 is rotatably disposed on the other end of the first lever 720, and the other end of the first connecting rod 730 is rotatably and slidably disposed on the upper base plate of the upper adjustment mechanism. Thus, when the first lever 720 swings, a horizontal displacement can be generated between the first connecting rod 730 and the first lever 720. At this time, the first connecting rod 730 and the first lever 720 will not be jammed.
[0108] Therefore, when the drive device 400 rotates, the first cam 710 will rotate synchronously, and then the first cam 710 will drive the first lever 720 to move, causing the upper slider 150 to move up and down.
[0109] Similarly, specifically, the second transmission assembly 800 includes components such as a second cam 810, a second lever 820, and a second connecting rod 830.
[0110] The drive unit 400 is used to drive the second cam 810 to rotate; wherein the drive shaft of the drive unit 400 extends into the interior of the housing 130, the second cam 810 is located inside the housing 130 and is mounted on the drive shaft.
[0111] A second follower 840 is provided at one end of the second lever 820, and the second follower 840 is used to engage with the second cam 810; wherein, the middle part of the second lever 820 is rotatably connected to the seat assembly 100 through a hinge shaft; specifically, the middle part of the second lever 820 is hinged to the second lever seat, and the second lever seat can be fixed to the housing of the seat assembly 100.
[0112] One end of the second connecting rod 830 is rotatably disposed on the other end of the second lever 820, and the other end of the second connecting rod 830 is rotatably and slidably disposed on the lower base plate of the lower adjustment mechanism. Therefore, when the second lever 820 swings, a horizontal displacement can occur between the second connecting rod 830 and the second lever 820, preventing the second connecting rod 830 and the second lever 820 from becoming jammed.
[0113] Therefore, when the drive device 400 rotates, the second cam 810 will rotate synchronously, and then the second cam 810 will drive the second lever 820 to move, causing the lower slider to move up and down.
[0114] The first cam 710 and the second cam 810 of this disclosure have a phase difference of 180°, so that the first transmission assembly and the second transmission assembly have opposite motion actions, and the upper slider 150 and the lower slider have opposite motion directions.
[0115] In one embodiment, a spring 750 is provided between the first lever 720 and the second lever 820. The spring 750 is in a pre-stretched state, thereby enabling the spring 750 to apply tension to the first lever 720 and the second lever 820, causing the first follower 740 of the first lever 720 to be in close contact with the first cam 710, and causing the second follower 840 of the second lever 820 to be in close contact with the second cam 810.
[0116] The riveting device disclosed herein, through the use of levers, can meet the requirements of high riveting pressure. Combined with a servo motor-driven cam, it greatly improves riveting speed and efficiency. Compared to the riveting mode output by a hydraulic cylinder, the riveting device disclosed herein has a smaller module size and higher riveting efficiency.
