Description

Technical Field

[0001] The invention belongs to the technical field of spot welding machines, and in particular relates to a manufacturing device for hardware accessories. Background Art

[0002] The spot welder adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other electrode to form an instantaneous heat fusion 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 without damaging the internal structure of the welded workpiece. The welding machine uses the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the spot welding rod and the material to be welded to achieve the purpose of combining them. Hardware accessories are often welded with spot welders. For example, a manufacturing equipment for hardware accessories is proposed in patent announcement number CN210060096U.

[0003] When an existing spot welding machine welds hardware accessories, the electrode and the workpiece frequently contact and apply pressure. As the number of welding times increases, the friction between the electrode and the workpiece will cause the electrode end surface to gradually wear and form pits. At the same time, if the welding parameters are set unreasonably, such as the welding current is too large or the welding time is too long, the electrode end surface will be locally overheated, causing the electrode material to soften, thereby aggravating the wear and forming pits. When pits appear on the spot welding machine electrode, the contact area between the electrode and the workpiece will be reduced, causing the welding current density to increase locally, thereby causing the weld to overheat in some areas and insufficient welding in other areas, resulting in uneven welding strength. However, traditional spot welding machines lack detection of the electrode end surface, so there is a problem of pits on the electrode affecting the welding quality of the spot welding machine.

[0024] The operating principle of the present invention is now described as follows: the hardware accessories and other parts to be welded are placed between the two electrode bodies 10, and then an electrical signal is transmitted to the PLC controller 4 through the foot switch (the foot switch is an existing mature technology and is not described in detail in this article), and the PLC controller 4 will control the cylinder 7 to drive the upper electrode holder 9 and the electrode body 10 to move downward, and the hardware accessories and the accessories to be welded are tightly fitted through the squeezing of the two electrode bodies 10, and then the PLC controller 4 controls the transformer inside the frame 2 to output the welding current, and the current is transmitted to the workpiece through the electrode body 10 , due to the resistance of the workpiece itself, when the current passes through, a large amount of resistance heat will be generated at the welding part, causing the metal at the welding part to quickly heat up to a molten state. After the welding current stops, the metal at the welding part quickly cools and solidifies under pressure to form a solid welding point, welding the hardware accessories and other accessories together. Then the PLC controller 4 controls the cylinder 7 to drive the upper electrode body 10 to move upward and separate from the lower electrode body 10, so that a welding point can be welded on the surface of the hardware accessories. Repeat the above steps to weld multiple welding points on the surface of the hardware accessories, and then weld the hardware accessories; During the welding of hardware accessories, if it is found that the solder joint has over-welding (when the solder joint has over-welding, the solder joint will become too large, too high, irregular in shape, and obviously different from the appearance of the normal solder joint, and the material around the solder joint may have burn marks, the surface becomes rough, discolored, and even cracks may appear, which can be seen by the operator with the naked eye), and after all the welding parameters of the electric welder are within the normal range, there is a situation where a pit appears on the end face of the electrode body 10 (the presence of the pit will change the contact form between the electrode and the workpiece, so that the current is concentrated at the pit, which will cause the current density in the local area around the pit to be too high, thereby causing the phenomenon of over-welding), the operator can send an electrical signal to the PLC controller 4 through the operating table 3; After receiving the electrical signal, the PLC controller 4 first controls the upper vertical electric push rod 12 to drive the upper linear motor 13 to move downward to the set position first, and then the PLC controller 4 controls the upper linear motor 13 to work, and the upper linear motor 13 drives the upper detection component 16 to move to the bottom of the upper electrode body 10, and then the PLC controller 4 controls the upper vertical electric push rod 12 to drive the upper detection component 16 to move upward, so that the upper electrode body 10 is inserted into the upper detection cylinder 161 to a certain depth. After the upper electrode body 10 is inserted into the detection cylinder 161, it will squeeze the multiple probes 26 in the detection cylinder 161, so that the probes 26 drive the lifting plate 25 and the conductive plate 28 to move downward together, so that the lifting plate When the pressure assembly on the lower side of 25 contacts the inside of the vertical box 24, the pressure assembly will control the vertical electric push rod 12 to stop working immediately through the PLC controller 4, and the conductive plate 28 will separate from the resistor plate 29. Then, the PLC controller 4 controls the upper double-axis motor 162 to rotate, and at the same time controls multiple conductive plates 28 to be electrically connected to the external power supply. The upper double-axis motor 162 drives the upper rotating plate 23 to rotate through the protective assembly 30, the horizontal box 18 and the guide plate 22. The rotating plate 23 drives the probe 26 to rotate along the lower end surface of the upper electrode body 10 through the vertical box 24. When the double-axis motor 162 drives the probe 26 to rotate one circle (one circle can fully detect an area on the lower end surface), the PLC controller 4 will control the micro When the motor 20 is working, the micro motor 20 will drive the first threaded rod 19 to rotate, and drive the first threaded cylinder 21 to move through the threaded cooperation. The first threaded cylinder 21 will drive the rotating plate 23 and the multiple probes 26 to move a set distance toward the center of the lower end surface of the electrode body 10 through the guide plate 22, so that the multiple probes 26 can detect other areas of the lower end surface of the electrode body 10. When the detection finds that there is a pit on the lower end surface of the electrode body 10, the probe 26 will be inserted into the pit under the action of the spring force when passing through the pit (when the pit is deeper, the length of the probe 26 inserted into the pit is deeper, and the probe 26 will not slide out of the pit. The squeezing force between the probe 26 and the pit will be transmitted to the horizontal box 18, as well as the protective cover 301 and the lower side of the horizontal box 18 The limiting ring 32, since the end of the rotating column 302 and the limiting groove on the inner wall of the limiting ring 32 are both arc-shaped structures, when the rotating column 302 continues to rotate driven by the dual-axis motor 162, the limiting column 31 inserted into the rotating column 302 will be separated from the limiting groove on the inner wall of the limiting ring 32, which can avoid the problem of the probe 26 and the pit squeezing each other and causing the probe 26 to bend). After the probe 26 is inserted into the pit, it will drive the conductive plate 28 to move upward a certain distance through the lifting plate 25 (the deeper the pit, the farther the probe 26 drives the conductive plate 28 to move upward). In the process of moving upward, the conductive plate 28 will contact the resistor plate 29, and the upper end of the resistor plate 29 is electrically connected to the PLC controller 4. When the conductive plate 28 and the resistor plate 29 are in contact,The current will be immediately transmitted to the PLC controller 4 through the resistor plate 29, and the deeper the pit is, the closer the conductive plate 28 will be to the position of the resistor plate 29 near the upper end, thereby reducing the resistance of the circuit connected to the PLC controller 4. When the external voltage remains unchanged, the current transmitted to the PLC controller 4 will be greater; After receiving the electrical signal, the PLC controller 4 records the electrical signal as a, and then controls the dual-axis motor 162 to stop working immediately, and controls the conductive plate 28 to be disconnected from the external power supply, and then controls the detection tube 161 to separate from the upper electrode body 10 (the separation step refers to the above working principle), and then the PLC controller 4 controls the upper transverse electric push rod 15 to work, so that the transverse electric push rod 15 drives the upper grinding assembly 37 to move to the bottom of the upper electrode body 10, and then the PLC controller 4 controls the grinding motor 38 to work, and controls the upper drive motor 34 to work to the set time (after receiving the electrical signal a, the PLC controller 4 converts the current signal into an analog signal recognizable by the PLC controller 4 through the internal current sensor module, and then triggers the grinding motor 38 control program according to the strength of the analog signal through the control program inside the PLC controller 4, and through the PLC controller 4 The control program is triggered. The timer function inside the LC controller 4 controls the running time of the grinding motor 38. The deeper the pit, the longer the working time of the grinding motor 38). The driving motor 34 drives the second threaded rod 332 to rotate, and drives the second threaded barrel 35 to move through the threaded fit. The second threaded barrel 35 drives the upper lateral electric push rod 15 and the grinding assembly 37 to move upward slowly through the moving plate 36. During the rising process of the grinding frame 371, the grinding motor 38 drives the transmission roller 372 to rotate together. The transmission roller 372 drives the grinding belt 39 to rotate together. The grinding belt 39 is used to grind the lower end surface of the upper electrode body 10 to make the lower end surface of the electrode body 10 flat (during the upward movement of the second threaded barrel 35, it will be squeezed to the pressing switch 41 through the pressing plate 40. The pressing switch 41 will control the buzzer 5 to work through the PLC controller 4 to remind the operator to replace the electrode body 10 with reduced welding performance after multiple grindings); When the grinding of the lower end surface of the upper electrode body 10 is completed, the PLC controller 4 will control the horizontal electric push rod 15 to drive the grinding assembly 37 to move away from the bottom of the electrode body 10, and repeat the above steps to move the detection assembly 16 to the bottom of the upper electrode body 10, and then control the angle motor 14 to drive the detection cylinder 161 and the polishing cylinder 45 to rotate 180 degrees, and then the PLC controller 4 controls the upper vertical electric push rod 12 to drive the polishing cylinder 45 to move upward, so that the ground electrode body 10 is inserted into the polishing cylinder 45 and contacts with the polishing disk 27. The surface of the polishing disk 27 is provided with a pressure assembly. When the electrode body 10 and the polishing disk 27 are squeezed to a certain degree, the electrode body 10 and the polishing disk 27 are pressed together. After the pressure component detects the set pressure value, the PLC controller 4 will control the upper vertical electric push rod 12 to stop moving, and control the dual-axis motor 162 to work. The dual-axis motor 162 drives the polishing disc 27 to rotate, and polishes the bottom of the electrode body 10. When the dual-axis motor 162 is working, the PLC controller 4 will control the linear motor 13 to move with a smaller amplitude, so that the polishing disc 27 moves on the lower end surface of the electrode body 10 to ensure the polishing effect. After polishing, the PLC controller 4 will control the polishing disc 27 to move away from the lower side of the upper electrode body 10, and repeat the above steps to detect and repair the lower electrode body 10.
