Description

Technical Field

[0001] The present invention relates to the technical field of assembly welding devices, and more specifically to an assembly welding device for brake production and processing. Background Art

[0002] The assembly welding device is one of the welding equipment used in brake production. Common assembly welding mainly consists of mechanical arms, welding wire feeding mechanisms, power supply mechanisms, sensors, and control systems. The specific process of the assembly welding device for brake production is as follows: the brake to be welded is limited to the welding position; under the control of the control system, the mechanical arm controls the welding mechanism to contact the area of ​​the brake to be welded, and the welding wire feeding mechanism, under the control of the control system, continuously and stably feeds welding wire to the welding structure, thereby assisting the welding mechanism in welding the brake; During the actual operation, we found that some granular protrusions appeared on the surface of some welding wires. In the later investigation, we found that the main reason for this situation is: the welding wire is exposed to the air environment for a long time or a certain amount of moisture adheres to its surface during transportation, so an oxide layer appears on its surface. When the above situation occurs, it may cause the following situations in the weld of the brake: 1. Weld porosity: the oxide in the oxide layer decomposes under the high temperature of welding and releases gas, which forms bubbles in the molten pool; 2. Weld slag inclusion: the impurities in the oxide layer fail to completely melt or float out of the molten pool, resulting in residual slag inclusions in the weld; 3. Poor weld formation: the oxide layer affects the melting characteristics of the welding wire, resulting in poor fluidity of the molten pool; the above situation causes the brake to have poor quality and ineffectiveness after welding, which can only be known through manual quality inspection in the prior art, thus causing a certain waste of manpower; Therefore, we are in urgent need of a brake production and processing assembly welding device to solve the above-mentioned technical problems.

A limiting plate 406 is installed on the inner ring plate A4001 near another group of air holes A404. A sponge ring 407 is installed on the inner side surface of the limiting plate 406. The adsorbed air inside the adsorption groove A403 is transmitted to the inside of the sponge ring 407 through another group of air holes A404 and the inner wall of the limiting plate 406, and the moisture and impurities adsorbed by the sponge ring 407 are recovered. The inner wall of the polishing chamber 401 near its inner side surface is installed with an inner ring plate B409, wherein a group of sealed and independent adsorption grooves B4011 can be formed between the inner side surface of the polishing chamber 401 and the outer wall of the inner ring plate B409. The adsorption groove B4011 is an annular structure. The adsorption air generated by the air pump group 602 is input into the adsorption groove B4011 through the Y-shaped conveying pipe 603, the storage device 6 and the three-hole pipe A402. The inner walls on both sides of the inner ring plate B409 are provided with air holes B410.

[0035] Reference Figures 1 to 8 As shown, the present invention provides an assembly welding device for brake production and processing. When the control system simulates the appearance of an oxide layer on the surface of the welding wire, each group of air pressure detectors 507 generates a simulated pressure value, and integrates the simulated pressure value to form a threshold range. The control system compares the real-time pressure value with the threshold range. When the real-time pressure value is within the threshold range, it is determined that an oxide layer has appeared on the surface of the welding wire section. When the control system detects that the real-time pressure value exceeds the upper limit of the preset threshold range, it is determined that a knot has appeared on the welding wire section.

[0036] In an embodiment of the present application, when knots appear on the surface of the welding wire, the diameter of this section of welding wire is 1.5 to 3 times the diameter of the welding wire where the oxide layer appears. When the control system determines that the welding wire is knotted, it remotely sends an early warning message to the staff through the internal communication module to remind them to go to the site for inspection.

Each group of rubber pads is in a deformed state under the compression of the welding wire. At this time, the overall volume of the corresponding sealed space B will change accordingly. Each group of air pressure detectors 507 then collects the pressure value in each group of sealed space B and transmits it to the control system to determine whether there is an oxide layer on the surface of the welding wire. Step 2: The control system determines that an oxide layer exists on the surface of a certain section of welding wire, and controls the corresponding mechanism inside the grinding chamber 401 to clean the oxide layer on the surface of the welding wire. The cleaned welding wire enters the interior of the re-inspection chamber 5, and the above step 1 is repeated. The rubber pad and the air pressure detector 507 provided inside the re-inspection chamber 5 are used to conduct a second re-inspection on the surface of the welding wire, so as to determine whether the oxide layer on the surface of the welding wire is cleaned; Grinding process: the air pump group 602 inputs a stable working current to generate adsorbed air and inputs it into the adsorption tank A403 through the Y-shaped delivery pipe 603, the storage device 6 and the three-hole pipe A402, and then enters the first treatment chamber 4 through welding, and contacts the inner side surface of the scraping plate 405 in an inclined state, and the inner side surface of the scraping plate 405 is used to scrape the surface of the welding wire. During the scraping process, the adsorbed air inside the adsorption tank A403 is transmitted to the scraping area on the surface of the welding wire through a group of air holes A404, and the dust after scraping is recovered; When the scraped welding wire passes through the inner side of the sponge ring 407, the sponge ring 407 absorbs the moisture that may remain on the surface of the welding wire, and at the same time, the adsorption groove A403 generates adsorption air which is transmitted to the inside of the sponge ring 407 through another group of pores A404, so as to recover the moisture adsorbed inside the sponge ring 407 and prevent the moisture from staying inside the sponge ring 407 for a long time; When the control system determines that an oxide layer appears in a certain section of the welding wire, the control system drives the power transmission mechanism B414 and the power transmission mechanism A413 to input a stable working current. The power transmission mechanism B414 generates a rotational force to drive the transmission gear 415 to perform a synchronous rotation operation. Under the drive of the transmission gear 415, the electric-controlled lifting column, the power transmission mechanism A413, and the grinding wheel 412 are controlled to move to the welding wire to be polished area. After the polishing welding enters the designated area inside the polishing cabin 401, the two sets of electric-controlled limit mechanisms 408 input a stable working current to limit the welding wire section to prevent the welding wire from moving during the polishing process. The electric-controlled lifting column inputs a stable working current to control the grinding wheel 412 and the power transmission mechanism A413 to move to the welding wire oxide layer area. The power transmission mechanism A413 inputs a stable working current to control the grinding wheel 412 to perform a polishing operation on the area. During the polishing process, the adsorbed air inside the adsorption groove B4011 is transmitted to the surface of the welding wire through the pores B410 to recover the impurities after polishing.
