Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to an automatic feeding device for welding nuts. Background Technology

[0002] In modern manufacturing, welding is an important joining process that is widely used in many fields such as automobile manufacturing, machining, and electronic equipment production.

[0003] Welding nuts are common connecting parts in welding processes and are used in large quantities. In the welding production process, the nut feeding process is one of the key factors affecting production efficiency and product quality. The traditional nut feeding method mainly relies on manual feeding. However, this manual feeding method has many disadvantages, the most prominent of which is that it is time-consuming and labor-intensive, which seriously restricts the improvement of production efficiency and the further development of enterprises.

[0004] Therefore, in order to solve the above problems, the applicant needs to design an automatic feeding device for welding nuts. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding device for welding nuts to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for welding nuts, comprising a support plate, and a laser welding machine fixedly mounted above the support plate.

[0007] It also includes: a support platform located below the laser welding machine, and a limiting groove for placing nuts is provided on the support platform. A connecting rod is fixedly provided below the support platform, and a rotating base is provided at the end of the connecting rod away from the support platform.

[0008] The control mechanism is located above the support plate and is used to drive the rotating base to rotate.

[0009] A buffer mechanism is installed above the support plate and is used for feeding nuts. The buffer mechanism includes a hollow sleeve that is fixedly connected to the support plate. A lifting rod is slidably installed on the inner side of the hollow sleeve. A buffer cylinder is fixedly installed at the end of the lifting rod away from the hollow sleeve and the buffer cylinder is located above the support platform.

[0010] Furthermore, the hollow sleeve is threaded with a threaded rod for locking the lifting rod, and a rotating handle is fixedly provided at the end of the threaded rod away from the hollow sleeve.

[0011] Through the above structural design, by setting up a threaded rod and a rotating handle, the height of the lifting rod inside the hollow sleeve is adjustable. The operator can quickly and accurately adjust the height of the buffer cylinder by rotating the handle, which not only ensures the alignment accuracy between the nut's falling position and the limiting groove, but also enhances the device's adaptability to nuts of different specifications.

[0012] Furthermore, the control mechanism includes a fixed shell fixedly connected to the support plate, a fixed rod fixedly mounted on the fixed shell, and an extension rod rotatably mounted on the fixed rod. The end of the extension rod away from the fixed rod passes through the fixed shell and is fixedly connected to a rotating disk, and the rotating disk is fixedly connected to a rotating base.

[0013] Through the above structural design, a transmission structure that links the extension rod inside the fixed shell with the rotating disk is adopted. The fixed rod forms a stable transmission fulcrum, giving the rotation control of the rotating base mechanical rigidity. This effectively reduces the impact of transmission clearance on positioning accuracy. The layout of the extension rod penetrating the fixed shell optimizes space utilization and ensures power transmission efficiency through the direct connection between the rotating disk and the rotating base, providing a reliable mechanical guarantee for the precise rotation of the welding station.

[0014] Furthermore, a linkage gear disk is fixedly installed on the extension rod, a rotating gear disk meshes with the linkage gear disk, and a servo motor is installed on one side of the rotating gear disk.

[0015] Through the above structural design, the meshing transmission design of the linkage gear disk and the rotating gear disk, combined with the precise drive of the servo motor, the digital control of the rotation speed and direction of the rotating base is realized.

[0016] Furthermore, a mounting rod is fixedly installed on the servo motor, and the end of the mounting rod away from the servo motor is fixedly connected to the fixed housing.

[0017] Through the above structural design, the mounting rod can easily support the servo motor, improving the stability and robustness of the servo motor during use.

[0018] Furthermore, a support sleeve is rotatably provided on the outer side of the extension rod, and a reinforcing member is fixedly provided on the support sleeve. A mounting plate is fixedly provided on the reinforcing member, and the mounting plate is fixedly connected to the fixed shell.

[0019] Through the above structural design, the composite support structure composed of the support sleeve and the reinforcement forms a multi-point rigid constraint in the middle of the extension rod. Through the distributed fixing method of the mounting plate, the cantilever beam structure of the extension rod is transformed into a multi-support continuous beam structure, which significantly improves the stability of the transmission system.

[0020] Furthermore, a support frame is fixedly installed below the support plate, and a support foot is fixedly installed at the bottom end of the support frame.

[0021] Through the above structural design, the support frame and support feet can easily support the support plate, thereby improving the stability of the device.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the automatic feeding device for welding nuts facilitates automatic feeding and has high working efficiency, as detailed below:

[0023] When using this automatic nut feeding device, rotate the handle to adjust the height of the lifting rod so that the height of the buffer cylinder from the bottom of the limiting groove is slightly greater than the height of the nut. Then, place several nuts inside the buffer cylinder. During welding, activate the control mechanism to rotate the rotating base. The rotation of the rotating base will drive the connecting rod to rotate, which in turn will drive the support platform to rotate. This facilitates the movement of the nuts in the limiting groove to the bottom of the laser welding machine for welding. At the same time, the nuts in the buffer cylinder can easily fall into the limiting groove, thus facilitating the welding of large batches of nuts and resulting in high work efficiency.

[0024] When this automatic nut feeding device is in use, the servo motor is started when welding nuts. The servo motor drives the rotating gear disk to rotate, which in turn drives the linkage gear disk to rotate, which in turn drives the extension rod to rotate, which in turn drives the rotating disk to rotate, and the rotating disk drives the rotating base to rotate. It is easy to operate and has high work efficiency. Attached Figure Description

[0030] 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.

[0031] like Figures 1-4 As shown, the present invention discloses an automatic feeding device for welding nuts, comprising a support plate 1, with a laser welding machine 10 fixedly mounted on top of the support plate 1, a support frame 15 fixedly mounted below the support plate 1, and a support foot 16 fixedly mounted at the bottom end of the support frame 15. It also includes: a support platform 13 mounted below the laser welding machine 10, with a limiting groove 14 for placing nuts on the support platform 13; a connecting rod 12 fixedly mounted below the support platform 13, with a rotatable rotating base 11 at the end of the connecting rod 12 away from the support platform 13; a control mechanism 2 mounted above the support plate 1, used to drive the rotating base 11 to rotate; and a buffer mechanism 3 mounted above the support plate 1, used for feeding nuts. The buffer mechanism 3 includes a hollow sleeve 30 fixedly connected to the support plate 1, with a lifting rod 31 slidably mounted on the inner side of the hollow sleeve 30, and a buffer cylinder 32 fixedly mounted at the end of the lifting rod 31 away from the hollow sleeve 30, with the buffer cylinder 32 located above the support platform 13.

[0032] The hollow sleeve 30 is threaded with a threaded rod 33 for locking the lifting rod 31, and a rotating handle 34 is fixedly provided at the end of the threaded rod 33 away from the hollow sleeve 30.

[0033] With the above structural design, during use, rotating the handle 34 adjusts the height of the lifting rod 31 so that the height of the buffer cylinder 32 from the bottom of the limiting groove 14 is slightly greater than the height of the nut. Then, several nuts are placed inside the buffer cylinder 32. During welding, the control mechanism 2 is activated, causing the rotating base 11 to rotate. The rotation of the rotating base 11 will drive the connecting rod 12 to rotate, and the rotation of the connecting rod 12 will drive the support platform 13 to rotate. This facilitates the movement of the nuts in the limiting groove 14 to the bottom of the laser welding machine 10 for welding. At the same time, the nuts in the buffer cylinder 32 can easily fall into the limiting groove 14, thus facilitating the welding of a large number of nuts and improving work efficiency.

[0034] The control mechanism 2 includes a fixed housing 20 fixedly connected to the support plate 1. A fixed rod 21 is fixedly mounted on the fixed housing 20, and an extension rod 22 is rotatably mounted on the fixed rod 21. The end of the extension rod 22 away from the fixed rod 21 passes through the fixed housing 20 and is fixedly connected to a rotating disk 23. The rotating disk 23 is fixedly connected to the rotating base 11. A linkage gear disk 24 is fixedly mounted on the extension rod 22. A rotating gear disk 25 meshes with the linkage gear disk 24. A servo motor 26 is mounted on one side of the rotating gear disk 25. A mounting rod 27 is fixedly mounted on the servo motor 26, and the end of the mounting rod 27 away from the servo motor 26 is fixedly connected to the fixed housing 20. A support sleeve 220 is rotatably mounted on the outer side of the extension rod 22, and a reinforcing member 28 is fixedly mounted on the support sleeve 220. A mounting plate 29 is fixedly mounted on the reinforcing member 28 and is fixedly connected to the fixed housing 20.

[0035] With the above structural design, when welding nuts, the servo motor 26 is started, which drives the rotating gear disk 25 to rotate. The rotation of the rotating gear disk 25 drives the linkage gear disk 24 to rotate. The rotation of the linkage gear disk 24 drives the extension rod 22 to rotate. The rotation of the extension rod 22 drives the rotating disk 23 to rotate. The rotating disk 23 drives the rotating base 11 to rotate. The operation is convenient and the work efficiency is high.

[0036] Working principle: When using this automatic nut feeding device, rotate the handle 34 to adjust the height of the lifting rod 31 so that the height of the buffer cylinder 32 from the bottom of the limiting groove 14 is slightly greater than the height of the nut. Then, place several nuts inside the buffer cylinder 32. During welding, start the servo motor 26. The servo motor 26 will drive the rotating gear disk 25 to rotate. The rotation of the rotating gear disk 25 will drive the linkage gear disk 24 to rotate. The rotation of the linkage gear disk 24 will drive the extension rod 22 to rotate. The rotation of the extension rod 22 will drive the rotating disk 23 to rotate. The rotating disk 23 will drive the rotating base 11 to rotate. The rotation of the rotating base 11 will drive the connecting rod 12 to rotate. The rotation of the connecting rod 12 will drive the support platform 13 to rotate. This facilitates the movement of the nuts in the limiting groove 14 to the bottom of the laser welding machine 10 for welding. At the same time, the nuts in the buffer cylinder 32 can easily fall into the limiting groove 14, thus facilitating the welding of a large number of nuts and achieving high working efficiency.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
