Description

Technical Field

[0001] This disclosure relates to the field of riveting nut machines, specifically to a riveting nut machine. Background Technology

[0002] A rivet nut machine is a mechanical device used to install rivets and nuts, and it is widely used in industries such as automobile manufacturing, home appliances, electronics, aerospace, and shipbuilding. The rivet nut machine uses pressure and technology to install the rivet nut onto the workpiece, providing a stable threaded connection point.

[0003] An automatic rivet nut machine (publication number: CN 211219556 U) disclosed includes a frame, a feeding machine, and a rivet nut mechanism. The rivet nut mechanism includes a pneumatic rivet nut gun, a rotary cylinder, a three-axis cylinder, a loading robot, a support, and a fixed plate. A guide rail B is provided on the top of the fixed plate. A vertical plate of a connecting plate with a slider B fixed externally to the guide rail B is located outside the fixed plate. The rotary cylinder is fixed outside the vertical plate of the connecting plate. A three-axis cylinder, fixed by a fixed seat, is located behind the rotary cylinder. The pneumatic rivet nut gun is fixed to the inner surface of the vertical plate of the connecting plate. A feeding pipe is provided on one side of the rivet nut gun's fixed seat. The lower end of the feeding pipe is located in a through hole on the horizontal plate of the support. The lower end of the feeding pipe is vertically aligned with a magnetic positioning seat on one side of the tank. The lower end of the loading robot is fixed inside the other side of the tank, and the upper part of the loading robot is fixedly connected to the rotary cylinder. This disclosed structure is simple, easy to use, and greatly improves production efficiency.

[0004] The pneumatic rivet nut gun, rotary cylinder, and three-axis cylinder components in the above application work together to achieve a simple structure and convenient use, but they cannot achieve the effect of automated movement and fixation of materials. Therefore, we propose a rivet nut machine. Utility Model Content

[0005] This disclosure proposes a rivet nut machine that solves the problem in related technologies that cannot achieve automated movement and fixing of materials.

[0006] According to one aspect, at least one embodiment of this disclosure provides a rivet nut machine, comprising: an operating table, a support frame fixedly connected to the top of the operating table, a nut punching machine disposed on the top of the support frame, a material feeding trough being provided on the top of the operating table, and a movable fixing device being disposed on the top of the operating table.

[0007] The movable fixing device includes a fixing plate, the bottom of which is fixedly connected to the top of the operating table. A motor is fixedly connected to the side of the fixing plate, and a threaded rod is fixedly connected to the output shaft of the motor. A limit rod is fixedly connected to the side of the fixing plate, a threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, a push rod is fixedly connected to the circumferential surface of the threaded rod, a connecting rod is fixedly connected to the side of the push rod, and a clamping rod is fixedly connected to the side of the connecting rod. The entire device is driven by the motor to rotate the threaded rod, thereby causing the push rod, connecting rod, and clamping rod to produce linear motion. This design enables precise object clamping and positioning, thus achieving precise operation, automated control, and significant stability of the movable fixing device.

[0008] For example, in at least one embodiment of the rivet nut machine disclosed herein, the circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod. The main purpose of this slidable connection between the threaded sleeve and the limiting rod is to provide precise control, limit the range, improve system stability, and ensure smooth operation of the device. It helps ensure that the threaded sleeve does not exceed its predetermined trajectory during operation, thereby improving the overall efficiency and safety of the device.

[0009] A fixed housing is fixedly connected to the top of the operating platform, and a sliding rod is slidably connected to the inner wall of the fixed housing. This sliding connection between the fixed housing and the sliding rod provides the device with high flexibility and precise control during operation. This structure not only improves the device's movement stability and avoids the effects of friction, but also provides precise adjustment functions to meet the needs of different tasks and operations, while ensuring system stability and protection.

[0010] The top of the fixed housing has a slot, and a spring is fixedly connected to the bottom of the sliding rod. The design of the slot, spring, and sliding rod provides a precise control and cushioning mechanism. The slot ensures the positioning and stability of the sliding rod within the fixed housing, while the spring provides elastic support and cushioning, enhancing the system's smoothness and adaptability. This design improves the equipment's operational accuracy, stability, and durability.

[0011] One end of the spring is fixedly connected to a locking pin, and the top of the locking slot is located on the displacement trajectory of the locking pin. This design can be applied to various mechanical devices, such as guiding systems, positioning devices, and shock absorption systems, to ensure that components maintain a stable and precise trajectory or position during movement.

[0012] One end of the sliding rod is located on the displacement trajectory of the push rod. The function of the sliding rod is closely related to the motion trajectory, accuracy, and stability of the push rod, ensuring that the system can operate smoothly and efficiently.

[0013] According to another aspect, at least one embodiment of this disclosure also provides a rivet nut machine, comprising: a gear fixedly connected to the circumferential surface of a threaded rod; a rack slidably connected to the top of an operating table; a square shell fixedly connected to one end of the rack; a collection groove formed on the top of the operating table; and a collection box slidably connected to the side of the collection groove. The gear and rack mechanism provides precise linear motion, while the collection groove and collection box are used for material collection and storage. This improves operational efficiency and reduces manual intervention.

[0014] For example, in at least one embodiment of the rivet nut machine provided in this disclosure, a compression spring is fixedly connected to the top inner side of the square shell, and a scraper is fixedly connected to one end of the compression spring. The combined design of the compression spring and the scraper is used to move and collect the stamped material.

[0015] The top of the collection box is positioned on the displacement trajectory of the scraper, and the gear meshes with the rack. By placing the collection box on the displacement trajectory of the scraper, it is ensured that the scraped material can be collected in a timely and accurate manner, avoiding material waste and scattering, and further improving the efficiency of the operation.

[0016] A handle is fixedly connected to the side of the collection box. The handle on the side of the collection box is mainly for convenient operation, movement and emptying of the collection box, which enhances the usability of the equipment and the user experience, and provides a more efficient and safer operating method.

[0017] The working principle and beneficial effects of this disclosure are as follows:

[0018] 1. This disclosure utilizes the coordinated operation of components such as a motor, threaded rod, threaded sleeve, limiting rod, and push rod to achieve the following: Starting the motor drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to move horizontally under the constraint of the limiting rod. The horizontal movement of the threaded sleeve drives the push rod to move horizontally, which in turn drives the connecting rod to move horizontally. The horizontal movement of the connecting rod then drives the clamping rod to move horizontally, thus moving the material to the desired position for processing. This design enables precise object clamping and positioning, thereby achieving precise operation, automated control, and significant stability of the moving and fixing device.

[0019] 2. In this disclosure, the use of gears, racks, motors, threaded rods, and other components in cooperation achieves the following: starting the motor causes the threaded rod to rotate, which in turn drives the gears to rotate. The gears then drive the meshing rack to move horizontally, which in turn drives the square housing to move horizontally. This horizontal movement of the square housing drives the compression spring to move horizontally, which in turn drives the scraper to move horizontally. The scraper then pushes the processed material into the collection box for collection, thereby improving operational efficiency and reducing manual intervention. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this disclosure or the prior art, the specific implementation methods of this disclosure will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this disclosure. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, it illustrates a nut-riveting machine according to an embodiment of the present disclosure, including: an operating table 1, a support frame 2 fixedly connected to the top of the operating table 1, a nut punching machine 3 provided on the top of the support frame 2, a material feeding trough 5 opened on the top of the operating table 1, and a movable fixing device 4 provided on the top of the operating table 1.

[0032] The mobile fixing device 4 includes a fixing plate 41, the bottom of which is fixedly connected to the top of the operating table 1. A motor 42 is fixedly connected to the side of the fixing plate 41, and a threaded rod 43 is fixedly connected to the output shaft of the motor 42. A limit rod 44 is fixedly connected to the side of the fixing plate 41. A threaded sleeve 45 is threadedly connected to the circumferential surface of the threaded rod 43, and a push rod 46 is fixedly connected to the circumferential surface of the threaded rod 43. A connecting rod 47 is fixedly connected to the side of the push rod 46, and a clamping rod 48 is fixedly connected to the side of the connecting rod 47. The entire device is driven by the motor 42 to rotate the threaded rod 43, thereby causing the push rod 46, the connecting rod 47, and the clamping rod 48 to produce linear motion. This design enables precise object clamping and positioning, thus achieving precise operation, automated control, and significant stability of the mobile fixing device 4.

[0033] In some examples, this also includes a sliding connection between the circumferential surface of the threaded sleeve 45 and the circumferential surface of the limiting rod 44. The primary purpose of this sliding connection between the threaded sleeve 45 and the limiting rod 44 is to provide precise control, limit the range, improve system stability, and ensure smooth operation of the device. It helps ensure that the threaded sleeve 45 does not exceed its predetermined trajectory during operation, thereby improving the overall efficiency and safety of the device.

[0034] A fixed housing 49 is fixedly connected to the top of the control panel 1, and a sliding rod 410 is slidably connected to the inner wall of the fixed housing 49. This sliding connection between the fixed housing 49 and the sliding rod 410 provides the device with high flexibility and precise control during operation. This structure not only improves the smoothness of the device's movement and avoids the effects of friction, but also provides precise adjustment functions to meet the needs of different tasks and operations, while ensuring the stability and protection of the system.

[0035] A slot 411 is provided on the top of the fixed housing 49, and a spring 412 is fixedly connected to the bottom of the sliding rod 410. The design of the slot 411, spring 412, and sliding rod 410 provides a mechanism for precise control and buffering. The slot 411 ensures the positioning and stability of the sliding rod 410 within the fixed housing 49, while the spring 412 enhances the smoothness and adaptability of the system's movement by providing elastic support and buffering. This design improves the operating accuracy, stability, and durability of the equipment.

[0036] One end of the spring 412 is fixedly connected to a locking post 413, and the top of the locking groove 411 is located on the displacement trajectory of the locking post 413. This design can be applied in various mechanical devices, such as guiding systems, positioning devices, and shock absorption systems, to ensure that components maintain a stable and accurate trajectory or position during movement.

[0037] One end of the sliding rod 410 is located on the displacement trajectory of the push rod 46. The function of the sliding rod 410 is closely related to the motion trajectory, accuracy, and stability of the push rod 46, ensuring that the system can operate smoothly and efficiently.

[0038] For example, such as Figures 1-5 As shown, press the locking pin 413 to adjust the sliding rod 410 to the required position of the material, start the motor 42, the motor 42 drives the threaded rod 43 to rotate, the rotation of the threaded rod 43 drives the threaded sleeve 45 to move horizontally under the restriction of the limiting rod 44, the horizontal movement of the threaded sleeve 45 drives the push rod 46 to move horizontally, the horizontal movement of the push rod 46 drives the connecting rod 47 to move horizontally, the horizontal movement of the connecting rod 47 drives the clamping rod 48 to move horizontally, the horizontal movement of the clamping rod 48 moves the material to the required position for processing, the push rod 46 moves to the sliding rod 410, the sliding rod 410 restricts the push rod 46 to continue moving.

[0039] like Figures 1-5As shown, this illustrates a rivet nut machine according to another embodiment of the present disclosure. The technical solution is largely the same as that of Embodiment 1, so only the differences are described in detail. These differences include: a collecting device 6 is provided on the circumferential surface of the threaded rod 43; the collecting device 6 includes a gear 61 fixedly connected to the circumferential surface of the threaded rod 43; a rack 62 is slidably connected to the top of the operating table 1; a square shell 63 is fixedly connected to one end of the rack 62; a collecting groove 64 is provided on the top of the operating table 1; and a collecting box 65 is slidably connected to the side of the collecting groove 64. The gear 61 and rack 62 mechanism provide precise linear motion, while the collecting groove 64 and collecting box 65 are used for material collection and storage. This improves operational efficiency and reduces manual intervention.

[0040] In some examples, a compression spring 66 is fixedly connected to the top inner side of the square shell 63, and a scraper 67 is fixedly connected to one end of the compression spring 66. The combined design of the compression spring 66 and the scraper 67 is used to move and collect the stamped material.

[0041] The top of the collection box 65 is located on the displacement trajectory of the scraper 67, and the gear 61 meshes with the rack 62. By placing the collection box 65 on the displacement trajectory of the scraper 67, it is ensured that the scraped material can be collected in a timely and accurate manner, avoiding material waste and scattering, and further improving the efficiency of the operation process.

[0042] A handle 68 is fixedly connected to the side of the collection box 65. The handle 68 on the side of the collection box 65 is mainly for the convenience of operation, movement and emptying of the collection box 65, which enhances the usability of the device and the user experience, and provides a more efficient and safer operating method.

[0043] For example, such as Figures 1-5 As shown, the motor 42 is started, and the motor 42 starts the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the gear 61 to rotate. The rotation of the gear 61 drives the rack 62, which meshes with it, to move horizontally. The horizontal movement of the rack 62 drives the square shell 63 to move horizontally. The horizontal movement of the square shell 63 drives the compression spring 66 to move horizontally. The horizontal movement of the compression spring 66 drives the scraper 67 to move horizontally. The horizontal movement of the scraper 67 pushes the processed material into the collection box 65 for collection. When the scraper 67 moves to the discharge trough 5, the compression spring 66 pushes the scraper 67 to move vertically and contact the bottom of the discharge trough 5.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
