Description

Technical Field

[0001] This utility model belongs to the field of double-grooved nut assembly technology, specifically relating to a swing fastening mechanism for processing double-grooved nuts. Background Technology

[0002] In modern production processes, the application of automated assembly equipment is becoming increasingly widespread, especially for the automated tightening of fasteners such as double-grooved nuts. Its efficiency and accuracy are directly related to product quality and production efficiency.

[0003] Traditional fastener tightening operations often require manual intervention, which is inefficient and makes it difficult to ensure consistency and accuracy. Tightening mechanisms often rely on robotic arms or manual movement when switching stations, which is not only inefficient but also lacks positioning accuracy, easily leading to offsets and errors during the tightening process. Existing fastener tightening mechanisms often lack modular design, making maintenance and component replacement inconvenient and affecting the flexibility and adaptability of the production line.

[0004] In view of this, we propose a swing fastening mechanism for machining double-grooved nuts to overcome the shortcomings of the prior art. Utility Model Content

[0005] The present invention aims to solve the technical problem in the prior art where the tightening of double-grooved nuts often relies on robotic arms or manual movement when switching work stations, and the double-grooved nut tightening parts are inconvenient to maintain and replace.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A swing fastening mechanism for processing double-grooved nuts includes a swing frame and a nut tightening head. The swing frame is driven by a swing motor to switch back and forth between the loading station and the tightening station of double-grooved nuts.

[0008] The nut head is located above one end of the swing frame and includes a circular support, two limiting blocks fixed to the top of the circular support and symmetrically positioned on both sides of the hexagonal nut that mates with the double-grooved nut, and two insertion blocks located inside the two limiting blocks and inserted into the round-headed grooved nut on the double-grooved nut. A fixed disk A driven to rotate by the nut tightening mechanism is fixed at the bottom of the nut head. The rotation of the fixed disk A by the nut tightening mechanism causes the nut head to rotate, thereby causing the double-grooved nut positioned on the nut head to rotate and be screwed into the external threaded pipe to be assembled.

[0009] Preferably, the swing motor is mounted on the operating table and the output shaft of the swing motor is fixedly connected to the end of the swing frame away from the head of the nut.

[0010] Preferably, the operating platform is provided with an annular guide groove, and during the swinging process driven by the swing motor, the guide rod at the bottom of the swing frame slides along the annular guide groove.

[0011] The guide rod at the bottom of the swing frame slides along the annular guide groove, which can effectively guide the movement of the swing frame and improve the smoothness and stability of the mechanism's movement. Preferably, the nut tightening mechanism includes a mounting bracket fixed to the bottom of the swing frame, a servo linear module mounted on the mounting bracket, a lifting seat fixed on the moving slide of the servo linear module, a screwing motor fixed on the lifting seat and driving the screwing shaft to rotate, and a fixed plate B fixed to the top of the screwing shaft.

[0012] Preferably, fixed plate A and fixed plate B are locked together by bolts and nuts.

[0013] Fixed plate A and fixed plate B are locked together by bolts and nuts, which facilitates the disassembly of fixed plate A and the removal of the nut head. Different nut heads can be replaced to accommodate the installation, positioning and tightening of double-grooved nuts of different sizes.

[0014] Preferably, the swing frame has a circular hole for the rotating shaft to move through. The circular hole design allows the rotating shaft to move freely, thus improving the rotating efficiency.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] This swing fastening mechanism for processing double-grooved nuts utilizes a swing motor to drive the swing frame to quickly switch between two workstations, improving the switching efficiency of the nut head. The cooperation between the guide rod and the annular guide groove effectively reduces vibration during movement, improves the smoothness and stability of the mechanism's movement, and ensures the guidance and accuracy of the swing frame during movement, thereby guaranteeing the tightening quality.

[0017] This swing-type fastening mechanism for processing double-grooved nuts features a locking design on fixed discs A and B, making nut head replacement quick and convenient. It adapts to the assembly and processing of double-grooved nuts of different sizes, significantly reducing changeover and maintenance time and improving production line flexibility. The coordinated use of limit blocks and insertion blocks ensures correct positioning of the double-grooved nut during tightening, preventing assembly problems caused by misalignment and improving product consistency and quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a swing fastening mechanism for processing double-grooved nuts, including a swing frame 1 and a tightening head 4. The swing frame 1 is driven by a swing motor 2 to switch back and forth between the loading station and the tightening station of the double-grooved nuts 3. The swing motor 2 is mounted on an operating table 5, and the output shaft of the swing motor is fixedly connected to the end of the swing frame 1 away from the tightening head 4. The operating table 5 is provided with an annular guide groove 6. During the swinging process driven by the swing motor 2, the guide rod 7 at the bottom of the swing frame 1 slides along the annular guide groove 6. The sliding of the guide rod 7 at the bottom of the swing frame 1 along the annular guide groove 6 can effectively guide the movement of the swing frame 1, improving the smoothness and stability of the mechanism's movement. The sliding of the guide rod 7 in the annular guide groove 6 can reduce vibration during the movement. The design of the annular guide groove 6 increases the guidance of the swing frame 1 during the movement, ensuring the accuracy of the swing frame 1 when switching stations.

[0028] The nut head 4 is located above one end of the swing frame 1, and the nut head 4 includes a circular support 41, two limiting blocks 42 fixed on the top of the circular support 41 and symmetrically limited on both sides of the hexagonal nut 31 that cooperates with the double-grooved nut 3, and two plug-in blocks 43 located inside the two limiting blocks 42 and inserted into the round-headed grooved nut 32 on the double-grooved nut 3.

[0029] The bottom of the nut head 4 is fixed with a fixed plate A44 driven to rotate by the nut tightening mechanism 9. The nut tightening mechanism 9 includes a mounting bracket 91 fixed to the bottom of the swing frame 1, a servo linear module 92 mounted on the mounting bracket 91, a lifting seat 94 fixed on the movable slide 93 of the servo linear module 92, a rotary motor 95 fixed on the lifting seat 94 and driving the rotary shaft to rotate, and a fixed plate B96 fixed to the top of the rotary shaft. The fixed plates A44 and B96 are locked together by bolts and nuts. The fixed plates A44 and B96 are locked together by bolts and nuts, which facilitates the disassembly of the fixed plate A44, and thus facilitates the disassembly of the nut head 4. Different nut heads 4 can be replaced to adapt to the installation, positioning, and tightening of double-grooved nuts 3 of different sizes.

[0030] The modular design of components such as the servo linear module 92, lifting platform 94, and screw motor 95 facilitates maintenance and replacement. By adjusting the servo linear module 92, the position of the screw-in nut head 4 can be flexibly controlled to adapt to different assembly requirements. The locking design of the fixed plates A44 and B96 makes replacing the screw-in nut head 4 quick and convenient, shortening changeover and maintenance time. By replacing different screw-in nut heads 4, different sizes and types of double-grooved nuts 3 can be accommodated, enhancing the equipment's versatility.

[0031] The swing frame 1 has a circular hole 8 for the rotating shaft to move through. The design of the circular hole 8 allows the rotating shaft to move through, so that the movement of the rotating shaft is not restricted, thus improving the rotating efficiency.

[0032] The fixed plate A44 is driven to rotate by the nut tightening mechanism 9, which in turn drives the nut tightening head 4 to rotate, thereby causing the double-grooved nut 3 positioned on the nut tightening head 4 to rotate and be screwed into the external threaded pipe to be assembled.

[0033] The swing motor 2 drives the swing frame 1 to swing, causing the screw-in head 4 to switch back and forth between the loading station and the screw-in station of the double-grooved nut 3. At the loading station, the automatic loading robot picks up the double-grooved nut 3 to be assembled and places it onto the screw-in head 4. The hexagonal nut 31 on the double-grooved nut 3 is limited by the limiting block 42, and the round-headed grooved nut 32 on the double-grooved nut 3 is positioned by the plug-in block 43, ensuring that the double-grooved nut 3 will not deviate during the process of screwing it onto the external threaded pipe. This facilitates the positioning of the double-grooved nut 3 and the automatic switching of stations for subsequent screw-in operations.

[0034] This mechanism can automatically switch between two workstations, reducing the frequency of manual intervention and improving the automation level of the production line. Because the swing-type fastening mechanism can quickly and accurately position the double-grooved nut 3 and screw it onto the external threaded pipe, it can significantly improve production efficiency. The cooperation of the limit block 42 and the insertion block 43 ensures the correct positioning of the double-grooved nut 3 during the tightening process, avoiding assembly problems caused by misalignment. The design of the swing-type fastening mechanism simplifies the traditional nut tightening operation process, making steps such as loading and tightening more convenient. Precise positioning and tightening control help improve product consistency and quality. Automated operation reduces manual labor and lowers labor intensity.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
