Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to a feeding mechanism for a metal ring welding equipment. Background Technology

[0002] Currently, welding equipment is a general term for various tools and machines used to complete welding processes, mainly including types such as electric arc welding, gas shielded welding, resistance welding, laser welding, ultrasonic welding, and friction welding. Its core components include a power supply, welding torch or welding gun, wire feeder, cooling system, and control system. It also needs to be equipped with auxiliary tools such as protective equipment, fixtures, positioners, and testing equipment.

[0003] In practical applications, metal rings need to be welded. The manufacturing process of metal rings includes steps such as raw material preparation, forming, processing and treatment, quality control, and post-processing. First, a suitable metal material is selected according to the requirements and cut into blanks. Then, the blanks are bent to form a ring shape.

[0004] During the welding process of the metal ring, the workers manually pick up the ring and then face the joint of the ring toward the welding equipment, which then welds the joint of the metal ring.

[0005] Regarding the aforementioned technologies, the inventors believe that during manual feeding, the mating points of the metal rings are prone to shifting, requiring workers to adjust the metal rings, thereby reducing the feeding efficiency of the metal rings. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a feeding mechanism for a metal ring welding equipment, which solves the technical problem that the joint of the metal ring is prone to displacement when feeding manually, and the operator needs to adjust the metal ring, thereby reducing the feeding efficiency of the metal ring.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A feeding mechanism for a metal ring welding equipment includes: a frame for supporting the feeding mechanism; a feeding rack rotatably mounted on the frame for holding metal rings; a pushing assembly mounted on the frame for pushing metal rings off the feeding rack; and a picking assembly mounted on the frame for picking up the metal rings.

[0009] Furthermore, the feeding rack is provided with support rods, and several support rods are spaced apart on the feeding rack, with the several support rods supporting the metal ring.

[0010] Furthermore, the feeding rack is provided with a positioning plate, and the positioning plate has support surfaces on both sides in the thickness direction, which support the end face of the metal ring.

[0011] Furthermore, the feeding assembly includes a pusher plate and a slider, the pusher plate is mounted on the slider, the frame is provided with a drive motor and a screw, the drive motor drives the screw to rotate, and the slider is threadedly connected to the screw.

[0012] Furthermore, a lifting cylinder is provided on the slider, the lifting cylinder is installed on the slider, and one end of the piston rod of the lifting cylinder is connected to the push plate.

[0013] Furthermore, a limit cylinder is provided on the frame, the limit cylinder is located on one side of the frame relative to the push plate, and a limit plate is provided on the limit cylinder, the limit plate being installed on the limit cylinder.

[0014] Furthermore, the material handling assembly includes a material handling cylinder, which is slidably mounted on the frame and equipped with grippers that grip the metal ring.

[0015] In summary, this application includes at least one of the following beneficial technical effects for the feeding mechanism of a metal ring welding equipment:

[0016] 1. In use, the metal ring is placed on the feeding rack. When welding the metal ring, the pushing component pushes the metal ring towards the picking component. The picking component grabs the metal ring and moves it to the welding equipment. This eliminates the need for manual feeding of the metal ring by the operator. The joint of the metal ring is less likely to shift, and the operator does not need to adjust the joint of the metal ring, thus improving the feeding efficiency of the metal ring.

[0017] 2. The accuracy of the metal ring's position on the frame is improved by setting up support rods and positioning plates;

[0018] 3. The lifting cylinder, limit cylinder, and material handling mechanism enhance the ease of movement of the metal ring on the frame. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a feeding mechanism for a metal ring welding equipment.

[0027] Reference Figure 1 A feeding mechanism for a metal ring welding equipment includes a frame 1, on which a feeding rack 2 is mounted, and metal rings are placed. The frame 1 is equipped with a pushing component 3 and a picking component 4. The pushing component 3 pushes the metal rings off the feeding rack 2, and the picking component 4 transports the pushed-out metal rings to the welding equipment for welding.

[0028] A rotating disk 11 is mounted on the frame 1, and a rotating motor 12 is mounted on the frame 1, with its output shaft connected to the rotating disk 11. In use, the rotating motor 12 drives the disk to rotate. Several feeding racks 2 are spaced around the rotating disk 11, and these feeding racks are arranged horizontally. Preferably, five sets of feeding racks 2 are spaced apart on the rotating disk 11.

[0029] Reference Figures 1-2 A feeding area 13 is formed on the frame 1. The rotating disk 11 drives the feeding rack 2 to rotate under the drive of the rotating motor 12. When the corresponding feeding rack 2 rotates to the feeding area 13, the pushing component 3 and the picking component 4 remove the metal ring on the corresponding feeding rack 2.

[0030] The feeding rack 2 is equipped with a support rod 21. The support rod 21 is horizontally arranged, and three support rods 21 are spaced apart along the arc direction on the feeding rack 2. When several metal rings are fitted on the feeding rack 2, the support rod 21 supports the metal rings, so that the metal rings can maintain a ring shape on the feeding rack 2.

[0031] Reference Figures 3-4 Furthermore, a positioning plate 22 is provided on the loading rack 2. The positioning plate 22 is rectangular in shape, and its length direction is parallel to the axis of the support rod 21. Support surfaces 221 are formed on both sides of the thickness direction of the positioning plate 22. When the metal ring is placed on the loading rack 2, the two ends of the metal ring are pulled away from each other, causing the two ends of the metal ring to press against the support surfaces 221 on both sides of the thickness direction of the positioning plate 22. Because the metal ring is elastic during processing, when the stress when the metal ring unfolds does not exceed the elastic limit, the metal will attempt to return to its original shape, thus causing the bent ends of the metal ring to press against the support surfaces 221 on both sides of the thickness direction of the positioning plate 22. By positioning the welded joint of the metal ring on the positioning plate 22, the accuracy of the metal ring's position on the loading rack 2 is improved.

[0032] Reference Figure 3 A first sensor 14 is provided on the side of the frame 1 near the loading area 13. The first sensor 14 detects whether a metal ring to be processed is fitted on the loading rack 2. When the first sensor 14 detects that a metal ring is fitted on the loading rack 2, the loading rack 2 rotates to the loading area 13. If the first sensor 14 does not detect that a metal ring is fitted on the loading rack 2, the rotating disk 11 drives the corresponding loading rack 2 to rotate over the loading area 13, thereby reducing the time that the loading rack 2 without a metal ring stays on the loading area 13.

[0033] To enable the metal rings to be pushed onto the loading rack 2, the pushing assembly 3 includes a push plate 31 and a slider 32. The slider 32 is slidably mounted on the frame 1, and a lifting cylinder 33 is installed on the slider 32. The lifting cylinder 33 is vertically mounted on the slider 32, and the piston rod of the lifting cylinder 33 is connected to the push plate 31. When the loading rack 2 rotates, the push plate 31 rises under the action of the lifting cylinder 33. After the loading rack 2 moves to the loading area 13, the push plate 31, driven by the lifting cylinder 33, inserts into one side of several metal rings. Then, driven by the slider 32, the push plate 31 pushes several metal rings out of the loading rack 2 in sequence.

[0034] A drive motor 34 and a screw 341 are mounted on the frame 1. The drive motor 34 is mounted on the frame 1, and the screw 341 is rotatably mounted on the frame 1. One end of the piston rod of the drive motor 34 is connected to the screw 341, and one end of the screw 341 passes through the slider 32, which is threadedly connected to the slide block 32. The drive motor 34 drives the screw 341 to rotate forward or backward, causing the slider 32 to slide back and forth on the frame 1 under the action of the screw 341. When all the metal rings on the loading rack 2 are pushed down, the drive motor 34 and the lifting cylinder 33 drive the push plate 31 to reset, so that the push plate 31 can push the subsequent metal rings on the loading rack 2.

[0035] When the pusher plate 31 pushes the metal ring, the pushing force of the pusher plate 31 only acts on the upper half of the metal ring, which causes the position of the metal ring to shift during the pushing process, affecting the subsequent welding of the metal ring. Therefore, a limit cylinder 15 is provided on the frame 1. The limit cylinder 15 is vertically installed on the frame 1, and the piston rod of the limit cylinder 15 faces the side closer to the loading rack 2. A limit plate 151 is provided at one end of the piston rod of the limit cylinder 15. The limit plate 151 is arranged parallel to the pusher plate 31 at intervals. When the pusher plate 31 pushes the metal ring, the limit plate 151 limits the position of the metal ring, thereby preventing the position of the metal ring on the loading rack 2 from shifting.

[0036] When it is necessary to grasp the metal ring, the limit cylinder 15 drives the limit plate 151 to descend, so that the metal ring can be grasped by the material handling component 4.

[0037] Reference Figures 2-3 To improve the ease of gripping the metal ring by the material handling assembly 4, the material handling assembly 4 includes a material handling cylinder 41 and grippers 42. The material handling cylinder 41 is slidably mounted on the frame 1. Two grippers 42 are arranged opposite each other on the material handling cylinder 41. The material handling cylinder 41 controls the two grippers 42 to move towards or away from each other. Furthermore, a second sensor 16 is installed on the side of the frame 1 near the unloading area. The second sensor 16 is located on the side of the loading rack 2 near the material handling cylinder 41. The second sensor 16 detects the end of the loading rack 2. When the second sensor 16 detects that the push plate 31 pushes the metal ring to the end of the loading rack 2, the material handling cylinder 41 drives the grippers 42 to move to the inside of the metal ring. Then, the grippers 42 move towards the side away from each other, supporting the inside of the metal ring. When the material handling cylinder 41 removes the metal ring, the push plate 31 pushes the metal rings off the loading rack 2 in turn. When all the metal rings on a feeding rack 2 are pushed down, the push plate 31 is lifted, and the rotating disk 11 drives the next feeding rack 2 to rotate towards the feeding area 13.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
