Description

Technical Field

[0002] At present, the repair welding of sprockets is a repair process, which is mainly used to repair the wear of the easily worn parts such as the chain nest of the sprocket. Repair welding usually adopts specific welding materials and processes to weld the deposited metal to the worn parts of the sprocket to restore its working size and performance.

[0003] However, the repair welding process of the sprocket is an exothermic process, which will produce a high-temperature welding area and the high temperature will easily lead to the generation of water vapor. The repair welding process of the sprocket will cause unstable welding quality due to the influence of high temperature and water vapor. That is, too high temperature will cause overheating of the welding area, causing sintering, deformation or cracking of the metal, thereby affecting the quality of the welded joint; water vapor may enter the welding area and react with the phosphide in the phosphating layer, causing the phosphating layer to lose its anti-corrosion performance; it can be seen that temperature control during the welding process is crucial.

[0004] Therefore, how to provide a sprocket repair welding device that can absorb and cool the high-temperature air in the repair welding area of ​​the sprocket and absorb and dry the water vapor to be suitable for a variety of high temperature and humid environments is an urgent problem that technical personnel in this field need to solve. Utility Model Content

[0062] In one embodiment of the welding positioning mechanism 5 of the present invention, the welding positioning mechanism 5 comprises:

[0063] A lifting device 51, wherein the lifting devices 51 are multiple and distributedly installed on the top of the welding platform, and the multiple lifting devices 51 are all electrically controlled and connected to the industrial computer 8;

[0064] Specifically, the driving parts of the lifting device 51 are all synchronous driving motors 511;

[0065] The XY axis positioning mechanism 52 comprises two first supports 521 arranged along the Y axis, a first transmission shaft, a first transmission belt, a synchronous shaft 522, a coupling 523, a first support motor 524, and a second support 525 arranged along the X axis, a second transmission shaft, a second transmission belt, and a second support motor 526. The two first supports 521 are fixed in parallel at the lifting end of the lifting device 51 at intervals. The first transmission shafts are divided into two groups and each group is vertically rotatably connected to the two ends of the corresponding first supports 521. The first transmission belts are divided into two groups and are correspondingly wound around the first transmission shafts of each group. Slide blocks 5211 are installed on the two first transmission belts. Both ends of the synchronous shaft 522 are connected to the first transmission shafts on the opposite sides of the two groups through the coupling 523.

[0067] In addition, after the repair welding is completed and when the 3D vision camera 7 detects the welding points of the sprocket, the second support 525 slides along with the slider 5211 to a position close to the first support motor 524, and this position is used as the initial position for the positioning mechanism to move and position. This can prevent the staff from directly contacting the welding arm when replacing the sprocket, improving safety.

[0069] In the above embodiment, a temperature and humidity sensor for detecting the internal temperature and humidity and an alarm are also installed inside the heat insulation cabinet 2. The temperature and humidity sensor and the alarm are both electrically connected to the industrial control computer 8. The temperature and humidity sensor detects the temperature and humidity inside the heat insulation cabinet 2 and sets a preset value. When the internal humidity and temperature reach the preset value, the alarm will sound to remind the staff that the working environment of the heat insulation cabinet 2 has exceeded the acceptable temperature and humidity range, and the welding should be stopped in time and adjusted.

[0070] In the above embodiment, the base 1 further includes a plurality of tool slots 13 for storing maintenance tools, and slot doors 14 are provided at the openings of the plurality of tool slots. Maintenance tools can be placed in the tool slots for easy access by the staff to maintain the equipment.

[0071] The working principle of the multi-environment universal sprocket repair welding equipment of the present utility model is as follows:

[0072] First, control the synchronous drive motor of the lifting device through the industrial control computer to lift the XY-axis positioning mechanism and simultaneously lift the automatic welding arm, so that the welding end of the automatic welding arm is far away from the sprocket supporting plate. Then, place the sprocket to be repaired on the sprocket supporting plate, control the lifting device to descend and make the welding end of the automatic welding arm flush with the plane where the sprocket is located. At this time, the second support is in the initial position. The sprocket can be scanned by the 3D vision camera to obtain sprocket image data, and at the same time, the image data is transmitted to the industrial control computer for data analysis and compared with the pre-input welding sprocket image information to determine the point information that needs to be welded and repaired. Then, control the second support motor and the first support motor to move and position the automatic welding arm according to the points, so that the welding head of the automatic welding arm performs welding repair at the corresponding points on the sprocket to be repaired. Because it is set in the heat insulation box body, it can prevent the high-temperature gas inside the welding from escaping and making the area near the equipment hot. And a cooling and dehumidifying device is set. The high-temperature moisture is sucked into the body of the cooling and dehumidifying device by the suction fan. After the air is cooled and dehumidified by it, the air is discharged through its air outlet, and then the air is assisted by the exhaust fan to flow back into the heat insulation box body to reduce the temperature and humidity inside the heat insulation box body, providing a suitable environment for the repair welding of the sprocket, avoiding the influence of high temperature and water vapor on the repair welding, and improving the welding quality.

[0073] During the air flow, since the rotating filter belt filters the air, the particulate impurities in the air are isolated in the heat insulation box body and will not enter the body of the cooling and dehumidifying device along with the inhaled air to ensure that the device is not damaged. At the same time, the shutter plate body set at the outermost end can further protect the filter belt to avoid the high-temperature residue from burning and damaging the filter body, and prolong the service life of the filter belt.

[0074] Therefore, the sprocket repair welding equipment provided by the present utility model, because it has a heat insulation structure and a cooling and dehumidifying device, while not affecting the external environment by discharging hot air, can also cool and dehumidify the high-temperature gas inside and the moisture generated by welding through the cooling and dehumidifying device, and make the processed gas flow back, so that the sprocket repair welding equipment can be applicable to various environments such as high temperature and humidity, improving the practicability of the equipment.

[0075] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
