Abstract
Description
Technical Field
[0001] This utility model belongs to the field of reactor welding technology, and specifically relates to a tank body rolling plate welding device for glass-lined reactors. Background Technology
[0002] After the sheet metal is rolled into a circle, the rolled sheet is prone to movement under gravity and its own rebound force, which can lead to misalignment at the beginning and end of the rolled sheet. This not only makes it difficult to accurately weld the beginning and end of the rolled sheet together, but also affects the quality of the weld after welding, thereby affecting the performance and safety of the pressure vessel.
[0003] A search revealed an existing technology publication, CN 219881639 U, which describes an automatic welding device for stainless steel composite plate coils. This device adjusts the diameter of the coil by adjusting the width of two external rollers and the height of an internal roller. A support platform is provided above the internal rollers for mounting a welding carriage. The welding carriage moves to allow the welding torch on it to weld the coil. However, gaps or overlaps easily appear at both ends of the coil, making welding impossible.
[0004] A search revealed an automated welding plate rolling machine with the existing technology announcement number CN221184230U. In this device, a support plate lifts and supports the inner surface of the rolled plate. Simultaneously, electromagnets on both sides of the support plate are energized to attract the inner surface of the plate, causing the two ends of the plate to move relative to each other and close. A welding head above then performs welding. Finally, a conveying mechanism horizontally transports the plate outwards. However, the electromagnets in the device can only move the two ends of the plate synchronously. Due to the stress on the rolled plate, one end may be higher than the other, causing a significant deviation in the position of the electromagnets at the two ends. This results in the rolled plate failing to close or the joint deviating from the center of the support plate after closure, affecting the welding process.
[0005] Therefore, a welding device for the tank body roll plate of a glass-lined reactor is needed, which can control the alignment and welding of both ends of the roll plate and prevent stress from affecting the welding quality of the roll plate. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a welding device for the tank body roll plate of a glass-lined reactor. This invention controls the alignment of the two ends of the roll plate for welding through a fixing device, and can prevent quality problems such as cracking of the welded roll plate due to stress.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A welding device for the tank body of a glass-lined reactor includes a fixing device. The fixing device is located on one side of the plate rolling machine and is fixedly connected to a working platform, and a welding robotic arm is slidably connected to the fixing device. The fixing device includes a displacement mechanism, a clamping mechanism, a support frame, a motor II, and a threaded rod. The bottom of the support frame is fixedly connected to the working platform, two sets of displacement mechanisms are symmetrically arranged at both ends of the support frame, and the clamping mechanism is located at one end of the displacement mechanism.

The base of the welding robotic arm is threadedly connected to the threaded rod.
[0009] The displacement mechanism includes a sliding seat, sliding columns, motor I, electric push cylinder I, connecting seat I, and electric push cylinder II. The sliding seat is slidably connected to the support frame. A pair of sliding columns with connecting seat I at one end are slidably connected to the sliding grooves at both ends of the sliding seat, and several gear teeth are provided in the groove on one side of the sliding column. The cylinder body of electric push cylinder I is fixedly connected to the sliding seat, and the extended end is fixedly connected to the support frame. There is a pair of motors I, which are fixedly connected to both ends of the sliding seat through motor seats, and the output end of motor I passes through the through hole on the sliding seat and meshes with the gear teeth in the groove of the sliding column through a gear. There is a pair of electric push cylinders II, and the cylinder body of electric push cylinder II is fixedly connected to connecting seat I, and the extended end is fixedly connected to the clamping mechanism slidably connected to connecting seat I.
[0010] The clamping mechanism includes a sliding box, an electric motor, a lead screw, a clamping block, a slider, a protective plate, a connecting shaft, and springs. The sliding box is slidably connected to the guide rod on the connecting seat I via the slider, and the slider is fixedly connected to the extended end of the electric push cylinder II. The electric motor is fixedly connected to one end of the sliding box via the connecting seat, and the output end of the electric motor passes through a through hole on the sliding box and is fixedly connected to the lead screw rotatably connected inside the sliding box, with the threads at both ends of the lead screw rotating in opposite directions. The clamping block has an anti-slip sleeve on its outer side, and there is a pair of clamping blocks. The pair of clamping blocks are symmetrically slidably connected to the slide grooves at both ends of the sliding box, and one end of the pair of clamping blocks is threadedly connected to both ends of the lead screw, while the other end of the clamping block has several connecting shafts. There is a pair of protective plates, respectively located on both sides of the clamping block, and one end of the pair of protective plates is slidably connected to the connecting shaft via connecting plates. There are several springs, and the springs are located along the connecting shaft on one side of the protective plate.
[0011] The advantages of this utility model compared with the prior art are as follows:
[0012] 1) After the plate rolling machine rolls the steel plate into a coil, the two ends of the coil are brought close together to form a seam. The plate rolling machine controls the rotation of the coil so that the seam is turned to the side where the fixing device is located. Then, the displacement mechanism is controlled to drive the clamping mechanism to move so that the clamping mechanism is located on both sides of the seam to clamp the side of the coil. At the same time, the clamping mechanism is controlled to align and fit the two ends of the coil to prevent the two ends of the coil from being misaligned, which would affect the welding efficiency.
[0013] 2) After the welding robotic arm welds the two ends of the coil together, the clamping mechanism maintains the clamping state. After the stress on the coil disappears, the displacement mechanism and the clamping mechanism are retracted to prevent the weld from cracking due to stress deformation, which would affect product quality.
