Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to an automatic feeding spot welding machine. Background Art

[0002] Spot welding machine is a kind of mechanical equipment, which adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous heat welding is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece to be welded. During the use of the spot welding machine, manual loading and unloading operations are required, which is labor-intensive and has low processing efficiency.

The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0022] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0023] An automatic feeding spot welding machine comprises a processing table 1, wherein the processing table 1 is installed at the four corners of the bottom of the processing table 1, a collecting box 3 is installed on the shorter outer side of the processing table 1, a groove 101 is opened at the top length direction of the processing table 1, a conveyor belt 4 is installed on the inner side of the groove 101, and a plurality of feeding troughs 401 are opened at equal intervals in the top length direction of the conveyor belt 4, a storage box 5 is installed at one end of the top of the processing table 1 on the edge of one end of the groove 101, an observation window 6 is embedded on one side of the outer side of the storage box 5, a support frame 7 is installed at a corner of the top of the processing table 1, and an automatic spot welding machine 8 is installed at one end of the inner top of the support frame 7.

[0024] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The conveyor belt 4 is driven clockwise by a stepper motor, and each raised rectangular block on the top of the conveyor belt 4 is the same size as each recessed loading trough 401, the opening cross-sectional size at the bottom of the storage box 5 is the same as the cross-sectional size of the loading trough 401, and the inner side surface size of the loading trough 401 is the same as the size of the workpiece to be processed, the bottom of the two baffles at the bottom of the storage box 5 fits with the raised part of the top of the conveyor belt 4 without generating friction, so that the loading trough 401 can only take away one workpiece each time it feeds.

[0025] Furthermore, the collecting box 3 is located on a shorter outer surface of the processing table 1 away from the material storage box 5, and the top of the collecting box 3 is located below the edge of one end of the inner bottom of the groove 101, so that the workpiece after spot welding can fall into the collecting box 3 for collection.

[0026] For details, please refer to Figure 1 and Figure 2 After each stepping process, the conveyor belt 4 moves the length of two feeding slots 401. There is a linkage program design between the automatic spot welding machine 8 and the stepping drive motor inside the conveyor belt 4. Three seconds after the automatic spot welding machine 8 finishes spot welding and rises upward, the stepping drive motor rotates once, thereby realizing automatic feeding.

[0027] The working process of the utility model is as follows: using an automatic feeding spot welding machine designed by the present invention, in the process of using the electric welding machine to spot weld the production and processing workpieces, the workpieces are first stacked inside the storage box 5, and at the same time, the workpiece at the bottom is just stuck on the inner side of a loading trough 401 on the conveyor belt 4. At this time, the stepper motor inside the conveyor belt 4 rotates once, so that the workpiece stuck inside the loading trough 401 moves a stepping stroke to the bottom of the automatic spot welding machine 8. At the same time, another loading trough 401 on the conveyor belt 4 is now located below the storage box 5 and is equipped with the next workpiece. After the automatic spot welding machine 8 completes the spot welding of the workpiece at this time, the conveyor belt 4 continues to rotate once, so that the next workpiece moves to the bottom of the automatic spot welding machine 8 for spot welding, and this is repeated, thereby realizing automatic feeding, and the workpiece after spot welding can fall into the storage box 5 for collection, thereby effectively improving the processing efficiency of the electric welding machine.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
