Technical Field

[0001] The utility model relates to the technical field of sewing machine production, in particular to an automatic forming welding device for a bottom beam of a sewing machine frame. Background Art

[0002] The bottom beam is a key component of the sewing machine frame, responsible for supporting the entire machine body and transmitting movement force. The bottom beam is usually made of metal materials, such as steel or iron. Welding is a common method for connecting metal parts together. The welding process can be used to weld parts to the bottom beam, providing strong connection strength and stability.

[0003] The existing automatic welding device for bottom beams usually places the bottom beams and parts to be welded on a transmission device, transports the bottom beams and parts to the welding area through the transmission device, and welds the parts to the bottom beams through an automatic welding robot. However, the bottom beams are usually hollow structures, which can easily cause the bottom beams to deform during production, processing and transportation. The existing devices are difficult to correct the shape of the bottom beams during the welding process, and the deformation of the bottom beams can easily affect the welding accuracy, thereby affecting the product quality.

[0004] Therefore, in view of the above problems, an automatic forming welding device for the bottom beam of a sewing machine frame has been developed, which can correct the shape of the bottom beam to prevent the bottom beam from deforming and affecting the welding accuracy. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices that it is difficult to correct the shape of the bottom beam during welding, and deformation of the bottom beam is likely to affect the welding accuracy, thereby affecting product quality, the utility model provides an automatic forming welding device for the bottom beam of a sewing machine frame, which can correct the shape of the bottom beam and avoid deformation of the bottom beam that affects the welding accuracy.

[0006] The technical solution of the utility model is:

The upper part of the base is rotatably connected to the conveyor belt, the fixed blocks are evenly connected to the conveyor belt, the hanger is connected between the front and rear sides of the right part of the base, and the automatic welding robot is slidably connected to the hanger. The bottom beam to be welded is clamped between two adjacent fixed blocks, and the parts to be welded are placed on the upper sides of the front and rear parts of the bottom beam. The bottom beam and the parts are moved by the conveyor belt. When the bottom beam moves to the bottom of the hanger, the automatic welding robot moves back and forth on the hanger for welding. The hanger is provided with a correction mechanism for correcting the shape of the bottom beam.

The contact blocks are pressed to move toward the side close to each other. The springs are compressed and the contact blocks are placed on the bottom beam. The springs rebound and drive the contact blocks to move away from each other, so that the fixing frame can be fixed on the bottom beam. At the same time, under the action of the spring, the fixing frame can be located in the middle position of the contact blocks. Then, the parts to be welded are placed on the fixing frame, and the parts are clamped and limited by the limiting columns.

DETAILED DESCRIPTION

[0021] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0022] An automatic forming welding device for sewing machine frame bottom beam, such as Figure 1 As shown, it includes a base 1, a conveyor belt 2, a fixed block 3, a hanger 4, an automatic welding robot 5 and a corrective mechanism 6. The upper part of the base 1 is rotatably connected to the conveyor belt 2, and the fixed block 3 is evenly connected to the conveyor belt 2. The hanger 4 is connected between the front and rear sides of the right side of the base 1, and the automatic welding robot 5 is slidably connected to the hanger 4. The corrective mechanism 6 is provided on the hanger 4.

[0023] like Figure 1-Figure 3 As shown, the orthopedic mechanism 6 includes an electric push rod 60, an external orthopedic frame 61 and an internal orthopedic frame 62. The front and rear parts of the hanger 4 are connected to the electric push rod 60, the telescopic ends of the electric push rod 60 are connected to the external orthopedic frame 61, and the external orthopedic frame 61 is connected to the internal orthopedic frame 62. The edges of the external orthopedic frame 61 and the internal orthopedic frame 62 are inclined to facilitate the correction of the bottom beam.

[0024] When it is necessary to automatically weld the bottom beam of the sewing machine frame, the device can be used for operation. First, the device is installed in the operation area, and then the bottom beam to be welded is clamped between two adjacent fixed blocks 3, and the parts to be welded are placed on the upper sides of the front and rear parts of the bottom beam, and the bottom beam and the parts are driven to move by the conveyor belt 2. When the bottom beam moves to the bottom of the hanger 4, the electric push rod 60 can be started, and the telescopic end of the electric push rod 60 drives the outer orthopedic frame 61 and the inner orthopedic frame 62 to move toward the side close to each other, so that the outer orthopedic frame 61 is located on the outside of the bottom beam, and the inner orthopedic frame 62 is located on the inside of the bottom beam. The outer orthopedic frame 61 and the inner orthopedic frame 62 cooperate with each other to squeeze the bottom beam, so that the shape of the bottom beam can be corrected to avoid deformation of the bottom beam affecting the welding accuracy. Then, the automatic welding robot 5 moves back and forth on the hanger 4 to weld the parts and the bottom beam. After the welding work is completed, the conveyor belt 2 continues to run to export the bottom beam, and finally the electric push rod 60 can be closed.

[0025] like Figure 1 and Figure 4 As shown, a positioning mechanism 7 is also included, which includes a fixing frame 70, a limiting column 71, a contact block 72 and a spring 73. At least two contact blocks 72 are arranged on the upper sides of the front and rear parts of the bottom beam, and a fixing frame 70 is slidably connected between two adjacent contact blocks 72. A baffle is provided on the fixing frame 70 to limit the parts placed on the bottom beam. The fixing frame 70 is connected to the limiting column 71, and the upper part of the limiting column 71 is a conical structure to facilitate docking with the parts. Springs 73 are connected between the left and right sides of the fixing frame 70 and the adjacent contact blocks 72.

[0026] The positioning mechanism 7 of the device can be used to position the parts that need to be welded. Before welding, the contact block 72 can be pressed to move it toward the side that is close to each other. The spring 73 is compressed, and then the contact block 72 is placed on the bottom beam. The spring 73 rebounds and drives the contact block 72 to move toward the side that is away from each other, so that the fixing frame 70 can be fixed on the bottom beam. At the same time, under the action of the spring 73, the fixing frame 70 can be located in the middle position of the contact block 72. Then, the parts that need to be welded are placed on the fixing frame 70, and the parts are clamped and limited by the limit column 71, which can avoid the position of the parts from being offset and affecting the welding accuracy. After the welding work is completed, the contact block 72 can be pressed again to remove it from the bottom beam.

[0027] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
