Technical Field
[0001] This utility model relates to the field of riveting machines, and in particular to a level gauge nameplate riveting machine. Background Technology
[0002] In industrial production, level gauges are crucial instruments used to measure the levels of liquids, solids, and other materials. Their housings not only protect the internal precision components but also require nameplates to display important information such as product model, parameters, and production details, facilitating later identification, maintenance, and traceability. Therefore, the quality of the nameplate installation on the level gauge housing is paramount, directly impacting the product's appearance integrity and the accuracy of information transmission.
[0003] Currently, the installation of nameplates on level gauge housings is traditionally accomplished through manual riveting or single-station riveting equipment. Manual riveting requires operators to manually position the nameplate relative to the housing and then apply pressure using tools to complete the riveting action. This method is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale production, but also prone to problems such as nameplate positioning deviations and uneven riveting force due to the subjectivity and instability of manual operation. This can lead to misaligned, loose, or even detached nameplates after riveting, severely affecting product consistency and reliability.
[0004] While existing single-station riveting equipment reduces manual intervention to some extent, it can only rivet one nameplate at a time. For level gauge housings that require multiple nameplates, multiple positioning, clamping, and operations are needed, which not only increases the equipment's operating time and process complexity but may also further reduce riveting accuracy due to the accumulation of positioning errors from multiple clamping operations. Utility Model Content
[0005] Based on this, it is necessary to provide a level gauge nameplate riveting machine to address the aforementioned technical problems. This machine effectively eliminates the inefficiency of manual riveting and overcomes the limitation of single-station equipment processing only one nameplate at a time. It enables simultaneous or continuous high-efficiency riveting of multiple nameplates, significantly shortening equipment operating time, simplifying production processes, and substantially increasing production capacity per unit time, thus fully meeting the needs of large-scale production. Furthermore, by replacing manual positioning with automated positioning and operation, it avoids positioning deviations and uneven riveting force caused by the subjectivity and instability of manual operation. At the same time, it reduces the accumulation of positioning errors caused by multiple clamping operations, ensuring accurate nameplate positioning and uniform riveting force. This results in flat and secure riveted nameplates, effectively preventing skewing, loosening, or detachment, and significantly improving product consistency and reliability.
[0006] This utility model provides a level gauge nameplate riveting machine, comprising: A fixed frame has a lifting frame at its inner top, which can move longitudinally. A double-cavity shell is fixed at the inner bottom of the fixed frame. A nameplate is placed on the upper surface of the double-cavity shell, and a rivet is provided at the corner of the nameplate. The first positioning plate is located below the lifting frame and is fixedly connected to the lifting frame; The second positioning plate is located below the first positioning plate and is spaced apart from the first positioning plate; Multiple stamping columns are arranged in a rectangular array, and the top of each stamping column is mounted through the second positioning plate. The central axis of the stamping column coincides with the central axis of the riveting component. Multiple elastic rods are inserted into multiple stamping columns. One end of each elastic rod is fixedly connected to the first positioning plate, and the other end can pass through the bottom end of the stamping column and abut against the riveting member. The middle section of each elastic rod is elastically connected to the stamping column.
[0007] In one embodiment, the fixing frame includes a top plate, a bottom plate, and studs; the top plate and the bottom plate are arranged opposite each other, and a plurality of studs are respectively arranged at the corners of the top plate or the bottom plate, with both ends of the studs passing through the top plate and the bottom plate respectively, and fixed by a first nut.
[0008] In one embodiment, the lifting frame includes a middle plate, linear bearings, and optical shafts; two linear bearings are symmetrically arranged on both sides of the upper surface of the top plate, and two optical shafts are respectively inserted through the two linear bearings; the middle plate is located between the top plate and the bottom plate, and the bottom end of the optical shaft is connected to the middle plate by fasteners.
[0009] In one embodiment, a flange is fixed to the upper surface of the middle plate, and a motor is fixed to the upper surface of the top plate. The drive shaft of the motor passes through the top plate and is inserted and fixed inside the flange. When the drive shaft of the motor rotates, the middle plate moves longitudinally.
[0010] In one embodiment, a distance sensor is provided on the upper surface of the top plate, which is used to detect the longitudinal movement distance of the optical axis. A limit sensor is provided on one side of the top plate, which faces the middle plate and is used to control the stroke of the middle plate and to limit the movement of the middle plate.
[0011] In one embodiment, the top of the outer surface of the stamping column is provided with an external thread, and the stamping column is mounted on the second positioning plate through the external thread. The top of the stamping column is provided with a mounting cavity, and the bottom of the mounting cavity is provided with a through hole. The elastic rod includes a mushroom punch and a spring. One end of the mushroom punch passes through and is fixed to the first positioning plate, and the other end of the mushroom punch is inserted into the through hole. The spring is sleeved on the mushroom punch and is located in the mounting cavity. The first positioning plate and the stamping column are elastically connected by the spring.
[0012] In one embodiment, a second nut is installed at the top of the mushroom punch, the second nut is located below the first positioning plate, and the bottom end of the second nut is engaged with the top of the mounting cavity and abuts against the spring.
[0013] In one embodiment, a limiting member is provided below the second positioning plate, one end of the limiting member passing through the second positioning plate and connected to the first positioning plate, and the other end of the limiting member being located below the second positioning plate.
[0014] Before use, the aforementioned level gauge nameplate riveting machine places the double-cavity housing (i.e., the level gauge housing) on the inner bottom of the fixed frame and limits its position. Then, the lifting component is activated to move longitudinally. During the descent of the lifting component, the stamping column first abuts against the nameplate on the surface of the double-cavity housing, and the riveting component placed on the nameplate is located inside the stamping column. As the lifting component continues to descend, the second positioning plate moves closer to the first positioning plate. During this process, the end of the elastic rod gradually moves closer to the bottom of the stamping column and finally abuts against the riveting component. The pressure is used to press and shape the riveting component, thereby deforming the riveting component and fixing the nameplate to the double-cavity housing. It effectively eliminates the inefficiency of manual riveting and overcomes the limitation of single-station equipment processing only one nameplate at a time. It enables simultaneous or continuous high-efficiency riveting of multiple nameplates, significantly shortening equipment uptime, simplifying production processes, and significantly increasing production capacity per unit time, fully meeting the needs of large-scale production. By replacing manual positioning with automated positioning and operation, it avoids positioning deviations and uneven riveting force caused by the subjectivity and instability of manual operation. At the same time, it reduces the accumulation of positioning errors caused by multiple clamping, ensuring accurate nameplate positioning and uniform riveting force, making the riveted nameplate flat and firm, effectively preventing skewing, loosening, or falling off, and greatly improving product consistency and reliability.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] The following is combined with Figures 1 to 5 This invention describes a level gauge nameplate riveting machine.
[0020] like Figure 1 and Figure 2As shown, in one embodiment, a level gauge nameplate riveting machine includes a fixed frame 100, a first positioning plate 500, a second positioning plate 600, multiple stamping columns 800, and multiple elastic rods 700; a lifting frame 200 is provided at the top of the fixed frame 100, and the lifting frame 200 can move longitudinally; a double-cavity housing 160 is fixed at the bottom of the fixed frame 100, and a nameplate 910 is placed on the upper surface of the double-cavity housing 160; a riveting member 920 is provided at the corner of the nameplate 910; the first positioning plate 500 is located below the lifting frame 200 and is fixedly connected to the lifting frame 200; the second positioning plate 600... Located below the first positioning plate 500 and with a gap between them; multiple stamping columns 800 are arranged in a rectangular array, and the top of each stamping column 800 is installed through the second positioning plate 600. The central axis of the stamping column 800 coincides with the central axis of the riveting member 920; multiple elastic rods 700 are respectively inserted into the multiple stamping columns 800. One end of the elastic rod 700 is fixedly connected to the first positioning plate 500, and the other end can pass through the bottom end of the stamping column 800 and abut against the riveting member 920. The middle section of the elastic rod 700 is elastically connected to the stamping column 800.
[0021] Before use, the aforementioned level gauge nameplate riveting machine places the double-cavity housing 160 (i.e., the level gauge housing) on the inner bottom of the fixed frame 100 and limits its position. Then, the lifting component is activated to move longitudinally. During the descent of the lifting component, the stamping column 800 first abuts against the nameplate 910 on the surface of the double-cavity housing 160, and the riveting component 920 placed on the nameplate 910 is located inside the stamping column 800. As the lifting component continues to descend, the second positioning plate 600 moves closer to the first positioning plate 500. During this process, the end of the elastic rod 700 gradually moves closer to the bottom of the stamping column 800 and finally abuts against the riveting component 920. The pressure is used to press and shape the riveting component 920, thereby deforming the riveting component 920 and fixing the nameplate 910 to the double-cavity housing 160. It effectively eliminates the inefficiency of manual riveting and overcomes the limitation that a single-station machine can only process one nameplate 910 at a time. It can achieve simultaneous or continuous high-efficiency riveting of multiple nameplates 910, significantly shortening equipment operating time, simplifying production processes, and significantly increasing production capacity per unit time, which can fully meet the needs of large-scale production. By replacing manual positioning with automated positioning and operation, it avoids problems such as positioning deviation and uneven riveting force caused by the subjectivity and instability of manual operation. At the same time, it reduces the accumulation of positioning errors caused by multiple clamping, ensuring accurate positioning of the nameplate 910 and uniform riveting force, making the riveted nameplate 910 flat and firm, effectively preventing skewing, loosening or falling off, and greatly improving product consistency and reliability.

Because studs 130 are used, by screwing multiple first nuts 140 onto the studs 130, with the first nuts 140 located above or below the top plate 120 or the base plate 110 respectively, the positions of the top plate 120 and the base plate 110 can be fixed, and the height of the fixing bracket 100 can be adjusted according to actual needs.
[0024] In one embodiment, the lifting frame 200 includes a middle plate 210, linear bearings 220, and optical shafts 230; two linear bearings 220 are symmetrically arranged on both sides of the upper surface of the top plate 120, and two optical shafts 230 are respectively inserted through the two linear bearings 220.

[0026] It should be noted that this embodiment only uses the limit sensor 420 and distance sensor 410 for conventional purposes. Their electrical connection and operation methods are not within the protection scope of this embodiment, and therefore will not be described in detail here. To achieve their basic functions, the distance sensor 410 and limit sensor 420 are connected to the motor 300 via a control drive unit. Similarly, the control drive unit is only for controlling the signal connection between the distance sensor 410 or limit sensor 420 and the electrodes; its specific structure or function is not within the protection scope of this embodiment, and therefore will not be described in detail here.

[0030] Specifically, a second nut 720 is installed at the top of the mushroom punch 710. The second nut 720 is located below the first positioning plate 500. The bottom end of the second nut 720 is engaged with the top of the mounting cavity 820 and abuts against the spring 730.
[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
