Description

Technical Field

[0001] The invention relates to the technical field of metal component welding, and more specifically to a limiting device for metal component welding. Background Art

[0002] The limit device is one of the commonly used positioning devices in the welding process of metal parts. The common limit device is mainly composed of machine tools, limit plates, support devices, moving mechanisms, power supply devices and control systems. The specific process of common limit devices for positioning metal parts is as follows: placing the metal parts to be welded on the surface of the limit plate, performing the limit operation under the control of the power supply device and the control system, and moving the parts after the limit is completed under the action of the moving mechanism, so that the welding device can perform welding operations on the joints of the metal parts;

[0003] Among them, the common limit plate is mainly composed of a limit support plate, an electric hydraulic column and a placement plate. The specific process of the limit plate fixing the metal parts is as follows: the metal parts are placed on the surface of the limit straight plate, and the limit straight plate is driven by the electric hydraulic column to contact its surface, thereby achieving the function of fixing the metal parts. During the process of the limit plate limiting the metal parts, the real-time status of the welding part of the metal parts needs to be monitored manually. Therefore, the common limit devices have the following problems in actual use:

[0004] 1. The status of the welding part of the metal parts cannot be monitored in real time. The main reason for this problem is that the existing limit device only performs limit positioning operations on the metal parts, and the real-time status of the welding part of the metal parts needs to be checked by the staff themselves, which wastes a certain amount of time and reduces the overall welding efficiency.

[0005] Second, it is impossible to process the abnormal parts of the welding of metal parts. The main reason for this problem is that during the welding process of existing metal parts, if the welding parts are uneven, they need to be polished manually to keep them smooth.

[0070] Step 1: The metal parts are placed inside the limit plate 203. The electric hydraulic column 214 starts to supply current to drive the limit long plate 207 to move toward the metal parts, and performs preliminary limit operation on the metal parts. Under the drive of the machine tool mechanism 1, the limit plate 203 drives the two groups of metal parts to move toward each other. When the welding parts of the two groups of metal parts are connected, the limit mechanism 2 reduces the moving speed of the limit plate 203. The metal parts in the extrusion state drive the limit support plate 209 and the extrusion column 217 to contact the pressure monitor 219 and generate the first pressure data L And transported to the monitoring system 5 for monitoring. After the limiting mechanism 2 drives the metal parts to move to the specified position, the monitoring system 5 determines the real-time status of the welding place of the two groups of metal parts according to the size of each group of first pressure data L. When it is determined that the welding place of the two groups of metal parts is in a normal state, the adsorption device 206 is supplied with current to generate adsorption wind force to transport to the surface of the first air chamber 210, thereby performing secondary limiting and fixing on the metal parts. After the fixing is completed, the limiting mechanism 2 drives the distance between the two groups of metal parts to move to the set welding distance, and the welding device performs the next step of welding operation;

[0071] Step 2: After the limiting mechanism 2 has limited the metal parts, it drives the protective shell 102 to contact the surface of the processing desktop 101 to prevent the smoke from the welding process from affecting the on-site environment. The first servo motor 104 starts to input current to generate a rotational force. The first servo motor 104 in the rotating state drives the sliding plate 106, the fixed plate 105 and the welding point of the metal parts to move closer to the middle of the processing desktop 101. When the metal parts reach the specified position, the welding device performs welding operations on the metal parts.

[0072] Step 3: When the monitoring system 5 detects that there is a protruding part at the welding position of the metal component, the limiting mechanism 2 drives the metal component to move to an appropriate grinding distance, and the cutting mechanism 3 grinds the corresponding protruding part of the metal component. During the grinding process, the cleaning mechanism 4 generates wind force and transports it to the inside of the spray gun 208 through the U-shaped conveying pipe 205 and the second empty chamber 211. The blowing wind force inside the spray gun 208 is transported to the grinding position of the metal component, and the blowing wind force drives the grinding debris to move to the surface of the cleaning mechanism 4 for adsorption and storage.

[0073] When the monitoring system 5 detects that there are concave spots at the welding position of the metal parts, the monitoring system 5 controls the communication device 504 to remind the staff to arrive at the site for inspection;

[0074] Step 4: When the metal parts are being polished, the angle adjustment device 303 is supplied with current to drive the support rod 302 and the polishing device 301 to move to the protruding part of the metal parts for polishing;

[0075] When metal parts are being welded, a fixed amount of current is fed into the dust storage chamber 402 to absorb the smoke and residue generated during the welding process. When metal parts are being polished, the wind power device 401 starts to input a rated current to recover the residue generated during the polishing process of the metal parts.
