Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a barbecue grill rotary automatic spot welding machine and a welding method. Background Art

[0002] A grill is a device used to cook food. It is usually composed of a metal frame and cross bars welded on the metal frame. It can be installed in a microwave oven or oven to provide support for heated or processed food and is widely used in life.

[0003] In the production process of the barbecue grill, it is usually necessary to weld a plurality of transverse ribs to the metal frame in sequence. In the related art, workers are usually required to press the transverse ribs to the metal frame or fix the transverse ribs to the metal frame in sequence through other fixing devices, and then weld the transverse ribs in sequence through a welding machine. Although the above method can realize the production of the barbecue grill, the process of fixing the transverse ribs to the metal frame in sequence and the process of welding in sequence will make the welding production efficiency of the barbecue grill low. Summary of the invention

[0004] In order to solve the above technical problems, the present invention aims to provide a barbecue grill rotary automatic spot welding machine and a welding method to solve the technical problem of low production efficiency of existing barbecue grill welding.

[0005] First aspect

[0006] The barbecue grill rotary automatic spot welding machine provided in this application adopts the following technical solutions:

[0007] The barbecue grill rotary automatic spot welding machine comprises a disc frame, a rotating motor for driving the disc frame to rotate is installed at the lower end of the disc frame, a plurality of positioning plates are arranged on the disc frame, and the plurality of positioning plates are equidistantly arranged around the axis of the disc frame, a limiting ring groove for placing a frame in the barbecue grill is provided on the positioning plate, a plurality of limiting straight grooves for placing transverse ribs in the barbecue grill are provided on the positioning plate, the limiting straight grooves are connected with the limiting ring grooves, a welding hole for welding the frame and the transverse ribs is provided on the positioning plate, and a welding mechanism for welding the transverse ribs and the frame is provided on one side of the disc frame.

The welding mechanism also includes a first driving component for driving the upper electrode block to rise and fall, and a second driving component for driving the lower electrode block to rise and fall.

[0010] By adopting the above technical solution, current can be transmitted to the upper electrode block and the lower electrode block through the electric control cabinet.

At the same time, the limit sleeve will limit the up and down sliding direction of the transmission column, thereby realizing the lifting of the upper mounting plate and making the upper mounting plate only liftable in the direction perpendicular to the ground, thereby realizing the lifting of the upper electrode block.

After the upper mounting plate is reset, the upper cleaning plate will also be reset, and the upper cleaning block will cancel the abutment with the lower cleaning block. At this time, the support spring will be reset, and the lower cleaning block will move up to clean the welding joints of the frame and the transverse reinforcement again. After the lower mounting plate is reset, the lower cleaning block will move down and clean the welding joints of the frame and the transverse reinforcement for the last time. Therefore, in this process, the lower cleaning block will move up and down four times, repeatedly cleaning the welding joints of the frame and the transverse reinforcement, and the upper cleaning block will move up and down twice, cleaning the welding joints of the frame and the transverse reinforcement twice, thereby greatly reducing the residual amount of welding slag at the welding joints of the frame and the transverse reinforcement.

[0045] Start the first drive motor 441, the first drive motor 441 can drive the reducer 442 to rotate, and then the reducer 442 drives the turntable 443 to rotate, so that one end of the upper transmission rod 444 rotates with the turntable 443, and then the transmission plate 445 and the transmission column 446 are reciprocated and lifted. At the same time, the limit sleeve 448 will limit the up and down sliding direction of the transmission column 446, so as to realize the lifting and lowering of the upper mounting plate 447, thereby realizing the up and down lifting of the upper electrode block 41.

[0046] The second driving assembly 45 includes a lower mounting platform 451, which is arranged on the ground and is arranged in a rectangular parallelepiped shape. Two lower cylinders 452 are arranged on the lower mounting platform 451, and the lower cylinders 452 are respectively located on both sides of the lower mounting platform 451. One end of the lower cylinder 452 away from its own telescopic end is hinged on the lower mounting platform 451. A lower mounting plate 453 is slidably connected to the lower mounting platform 451, and the lower electrode block 42 is fixedly connected to the upper end of the lower mounting plate 453. Two steering wheels 454 are rotatably connected to the lower mounting platform 451, and the axis of the steering wheel 454 is parallel to the ground. Two steering wheels 454 are arranged and are respectively located on both sides of the lower mounting platform 451.

Then, the rotating motor 2 is started, so that the rotating motor 2 drives the disc frame 1 to rotate, and when the positioning plate 3 reaches a suitable welding position, the lower electrode block 42 can be driven to rise by controlling the second driving component 45, and then the upper electrode block 41 can be driven to descend by the first driving component 44, so that the upper electrode block 41 and the lower electrode block 42 are both in contact with the connection between the transverse rib and the frame, so that the current passes through the two connections and welds the connection between the two. Example 2

[0050] The difference from Example 1 is: Figure 4 , Figure 5 and Figure 6 , an upper cleaning plate 6 is fixedly connected to one side of the upper mounting plate 447, and the upper cleaning plate 6 is arranged parallel to the upper mounting plate 447. A plurality of upper mounting plates 61 are fixedly connected to the lower end surface of the upper cleaning plate 6, and the upper mounting plates 61 correspond to a plurality of welding points of the frame and the transverse ribs in the positioning plate 3. Four upper cleaning arc rods 63 are installed at the lower end of the upper mounting plate 61. In this embodiment, the upper cleaning arc rods 63 are installed on the upper mounting plate 61 by a rotation connection, and a torsion spring for limiting the rotation range of the upper cleaning arc rods 63 is installed between the cleaning arc rods and the upper mounting plate 61.

[0051] The four upper cleaning arc rods 63 are equidistantly arranged around the axis of the upper mounting plate 61, and the inner arc surfaces of the four upper cleaning arc rods 63 are all facing one side of the axis of the upper mounting plate 61. An upper cleaning block 62 is fixedly connected to the inner wall of the upper cleaning arc rod 63, and the cross section of the upper cleaning block 62 is set to be triangular and adapted to the welding position of the frame and the transverse rib in the barbecue grill.

[0052] Reference Figure 5 , Figure 6 and Figure 7 A lower cleaning plate 7 is fixedly connected to one side of the lower mounting plate 453. The lower cleaning plate 7 is arranged parallel to the upper cleaning plate 6. A plurality of lower mounting plates 71 are arranged on the upper end of the lower cleaning plate 7. The lower mounting plates 71 correspond to the upper mounting plates 61 one by one. A telescopic rod 72 is fixedly connected between the lower mounting plates 71 and the lower cleaning plate 7. A supporting spring 73 for supporting the telescopic rod 72 is arranged inside the telescopic rod 72.

[0053] Four lower cleaning arc rods 74 are installed at the upper end of the lower mounting plate 71, and the installation method of the lower cleaning arc rods 74 on the lower mounting plate 71 is the same as the installation method of the upper cleaning arc rods 63. The four lower cleaning arc rods 74 are equidistantly arranged around the axis of the lower mounting plate 71, and the inner arc surfaces of the four lower cleaning arc rods 74 are all facing the axis of the lower mounting plate 71. The inner wall of the lower cleaning arc rod 74 is fixedly connected with a lower cleaning block 75. The lower cleaning block 75 is made of the same material as the upper cleaning block 62, and is set to be a cleaning block with a certain water permeability.

[0054] A water supply pipe 8 is fixedly connected to both the upper cleaning plate 6 and the lower cleaning plate 7. One end of the water supply pipe 8 placed in the upper cleaning plate 6 or the lower cleaning plate 7 is divided into multiple diversion pipes 81. The diversion pipes 81 correspond one-to-one to the upper cleaning block 62 and the lower cleaning block 75, and the diversion pipes 81 are fixedly connected and communicated with the upper cleaning block 62 and the lower cleaning block 75.

[0055] During use, the water supply pipe 8 can be connected to the water supply equipment in the factory, and then water is supplied to the water supply pipe 8, so that the water flows into the cleaning block through the water supply pipe 8, so that the outer surfaces of the upper cleaning block 62 and the lower cleaning block 75 remain moist.

[0056] The implementation principle of the second embodiment is as follows: when the positioning plate 3 after welding is placed between the upper cleaning plate 6 and the lower cleaning plate 7 and the welding mechanism 4 welds the next positioning plate 3 again, since the lower mounting plate 453 rises first, the lower cleaning block 75 can abut against the welding part of the frame and the transverse rib, so that the lower cleaning block 75, the frame and the transverse rib are spaced and abut against each other, thereby cleaning the frame and the transverse rib.

[0057] Then the upper mounting plate 447 will descend, and the cleaning block in the upper cleaning plate 6 will abut against the welding joint of the frame and the transverse rib, so that the upper cleaning block 62 and the frame and the transverse rib are spaced apart and abut against each other. At the same time, the upper cleaning block 62 will abut against the lower cleaning block 75, and compress the supporting spring 73, so that the lower cleaning block 75 will move downward for a distance, and continue to clean the welding joint of the frame and the transverse rib during the movement.

[0058] Subsequently, after the upper mounting plate 447 is reset, the upper cleaning plate 6 will also be reset, and the upper cleaning block 62 will cancel the abutment with the lower cleaning block 75. At this time, the support spring 73 will be reset, and the lower cleaning block 75 will move up to clean the welding joints between the frame and the transverse ribs again. Subsequently, after the lower mounting plate 453 is reset, the lower cleaning block 75 will move down and clean the welding joints between the frame and the transverse ribs for the last time.

[0059] Therefore, in the above process, the lower cleaning block 75 will move up and down four times to repeatedly clean the welding points between the frame and the transverse ribs, and the upper cleaning block 62 will move up and down twice to clean the welding points between the frame and the transverse ribs twice.
