working principle:

The arc is ignited between the stud to be welded and the metal plate. When the stud and the plate are heated to a certain temperature, under the action of external force, the stud is sent into the welding pool on the plate to form a welded joint. There are two types of traditional arc stud welding: ordinary arc stud welding and capacitor energy storage arc stud welding. In the utility model, capacitor energy storage arc stud welding is adopted. The welding machine 2 discharges during welding, and the discharge of the energy storage capacitor The stored electric energy heats the gap between the welding stud and the plate to form a molten pool, and the welding torch assembly 14 completes the action of seeding the nail. After the discharge is completed, the energy storage capacitor is recharged until the next discharge.

When in use, the position parameters of the welding stud and the welding workpiece 22 need to be measured first, the program setting can be operated through the handheld box 7 or the touch screen PLC all-in-one machine 32, and the stepper motor driver 77 drives the X, Y, and Z axis motors to realize three-axis linkage control . The cable of the machine head is conveyed through the Z-axis, the nail feeding tube is connected to the welding torch assembly 14 through the connecting plate 85, and the "automatic nail measurement" button is clicked on the external hand-held box 7, the movable clamp 23 moves to clamp the welding workpiece 22, and the welding torch assembly 14 Move to the stud point, descend until it touches the workpiece 22, then lift 2-3mm away from the workpiece. The touch screen PLC all-in-one machine 32 records the current descending height in the Z-axis direction, and this position is the required processing height of the workpiece 22 . The specific process is as follows: 1. The movable clamp 23 is started to clamp the workpiece 22 firmly. 2. The device spits out the internal nails of the welding torch assembly 14 at the nail ejecting position, and then the Z-axis stepping motor moves to the upper limit. 3. The X-axis 8 moves to the top of the test point of the workpiece 22, the sliding table cylinder 87 falls, and the Z-axis gradually falls. 4. When the welding torch assembly 14 touches the surface of the workpiece 22, lift it up by 2-3 mm, and record the descending height of the Z axis. 5. The vibrating nail feeding mechanism 3 feeds the nails, and the driving lever assembly 91 is ejected. 6. The Z-axis motor drives the lever assembly 91 to drop until the head of the welding nail touches the workpiece 22, and the length of the nail is recorded. 7. The sliding table cylinder 87 rises, and the Z-axis machine head is lifted to a safe height. 8. The touch screen PLC all-in-one machine 32 records the position of the welding stud. 9. Going back to the origin of the coordinates, the execution mode of loosening the clamp 23 is divided into a manual operation mode and an automatic operation mode. The manual operation mode is manually controlled by the touch screen PLC integrated machine 32 and the hand-held box 7 to realize the welding operation. The specific process is: 1. Click the touch screen PLC integrated machine 32 to start the clamp 23 to clamp the workpiece 22. 2. Use the touch screen PLC integrated machine 32 to spit out the internal nail of the welding torch assembly 14 at the nail ejecting position, and then control the Z axis to move to the upper limit. 3. The vibrating nail feeding mechanism 3 feeds the nails, and the driving lever assembly 91 is ejected. 4. Move the welding torch assembly 14 to above the processing point of the workpiece 22 through the handheld box 7, and adjust the processing height along the Z axis. 5. Adjust the Z-axis motor to the specified height of the processing nail through the position of the welding nail recorded by the front touch screen PLC integrated machine 32. 6. The sliding table cylinder 87 falls, and the welding machine 2 discharges at the same time. 7. The welding nail contacts the surface of the workpiece 22 to form a molten pool, and the nail head is pressed into the molten pool. 8. The sliding table cylinder 87 rises, and the welding torch assembly 14 is lifted to a safe height. 9. Repeat steps 3-8 until the manual nail welding procedure is completed. 10. Return to the origin and loosen the clamp. The automatic working mode is to input actions and parameters into the touch-screen PLC all-in-one machine 32, and also supports the touch-screen PLC all-in-one machine 32 to read in the PLT format file through the data line, and download it to the stud welding controller 71 through the serial port, and the stud welding controller 71 STC89C52RC single-chip microcomputer is used as the main control chip.
