Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary brackets, and particularly relates to an auxiliary support seat for welding a tank body and a valve seat. Background Art

[0002] During the production process, steel cylinders are usually processed and produced in multiple parts separately, and finally assembled by welding. The steel cylinder as a whole includes an upper bottle body, a lower bottle body, a bottle bottom support, a bottle body lifting ring, a valve seat, etc., and the above parts are welded and assembled to complete the overall production.

[0003] The existing welding method is usually completed by manual operation, which is time-consuming and labor-intensive, with high labor intensity, low work efficiency and poor welding quality. With the development of science and technology, mechanized production methods have gradually replaced manual operations. However, the popularity of fully automated production methods is not enough, and the equipment for fully automated production is expensive, which is not suitable for small and medium-sized enterprises. Therefore, the welding method between the various components of the tank body is still mainly semi-automatic: manually placing the components of each part on the corresponding auxiliary bracket, and then using an automatic welding machine to weld the two parts together.

[0004] The welding method for the upper bottle body and the valve seat is as follows: 1. Manually place the valve seat on the top of the bracket, and then buckle the upper bottle body with the hole opened on the top of the valve seat. At this time, the through hole on the upper bottle body is aligned with the valve port on the valve seat. By driving the bracket to rise and fall, the upper half of the valve seat is passed through the through hole, and the large end face of the valve seat is snapped onto the inner bottom face of the upper bottle body. Finally, the two parts are welded and sewn by a fully automatic welding machine to complete the welding operation of the valve seat and the upper bottle body. However, there are certain problems with the above operation mode. First, the valve seat is placed manually by the operator, and there is no clamp for fixing the valve seat on the bracket, so the placed valve seat may be offset in position, which makes the through hole on the bottle body not aligned with the valve seat when the upper bottle body is placed; secondly, the alignment of the through hole on the upper bottle body and the valve port on the valve seat is judged by the operator's naked eye, so it cannot be guaranteed that the valve port on the valve seat and the through hole on the upper bottle body are in an absolutely aligned state. When the lifting bracket is subsequently started to lift the valve seat, the valve seat cannot pass through the through hole due to the misalignment of the valve port and the through hole. At this time, the operator has to adjust this situation, which is time-consuming and labor-intensive, and the production efficiency is not high; finally, after the upper half of the valve seat is passed through the through hole, since the upper bottle body is suspended by the bracket, and the valve seat indirectly supports the upper bottle body, the upper bottle body may be in an unbalanced state (the bottle body is tilted), and the valve seat may be skewed after welding, affecting the production quality of the tank body.

[0005] Therefore, in order to solve the above problems, ensure that the valve port on the valve seat is accurately aligned with the through hole on the upper bottle body, and at the same time ensure that the upper bottle body is in a balanced state when it is lifted up and suspended in the air (the bottom surface of the upper bottle body is parallel to the horizontal plane, and the bottle body does not tilt), and ensure the quality of the welding process, it is urgent to design an auxiliary support seat for welding the tank body and the valve seat. Utility Model Content

[0027] Example

[0028] like Figure 1 to Figure 2 As shown, an auxiliary support seat for welding a tank body and a valve seat specifically includes an operating workbench 100, which is installed below an automatic welding device. A calibration component 200 is provided at the center of the operating workbench 100. A valve seat placement groove 110 is provided on the operating workbench 100. In a semi-automatic welding operation, valve seats 400 to be welded can be uniformly placed in the valve seat placement groove 110, and can be taken one by one when needed, so as to avoid placing the valve seats 400 on the operating workbench 100 to affect the welding operation and the integrity of the workbench surface. A safety enclosure edge 120 is provided on the operating workbench 100, and the safety enclosure edge 120 is located on the other side opposite to the valve seat placement groove 110. The functions of the safety enclosure edge 120 are, first, to prevent the valve seat 400 from accidentally falling during the installation of the valve seat 400. The safety enclosure edge 120 is used to prevent the valve seat 400 from falling outside the operating workbench 100; second, to further isolate people other than the operators during the welding process to prevent them from approaching and avoiding personal injury to them caused by the welding equipment.

[0029] Furthermore, a valve seat 400 is fixedly placed on the calibration component 200, and an upper bottle body 300 is buckled on the calibration component 200. The lower end surface of the upper bottle body 300 abuts against the table surface of the operating workbench 100 to ensure that the upper bottle body 300 is in a leveled state and the bottle body is not skewed. A through hole 310 is opened at the center of the top of the upper bottle body 300, and the calibration component 200 aligns the through hole 310 with the valve port on the valve seat 400.

[0030] Furthermore, the calibration assembly 200 includes a calibration bottom block 210, a central support column 220 and a top elastic valve seat mounting assembly 230. The calibration bottom block 210 is mounted at the center of the operating workbench 100. The calibration bottom block 210 is a frustum structure. The diameter of the large end of the calibration bottom block 210 is equal to or smaller than the inner diameter of the upper bottle body 300 by 1-2 mm. The central support column 220 is mounted on the calibration bottom block 210. 0, and the upper end surface of the central support column 220 is not flush with the upper end surface of the calibration bottom block 210, and the upper end surface of the central support column 220 is higher than the upper end surface of the calibration bottom block 210, and the top elastic valve seat mounting assembly 230 is mounted on the top end surface of the central support column 220. Specifically, a mounting hole is provided on the upper end of the central support column 220, and the top elastic valve seat mounting assembly 230 includes a valve seat support seat 231, a hard spring 2 The valve seat support seat 231 is slidably mounted in the mounting hole, one end of the hard spring 232 is connected to the bottom surface of the mounting hole, and the other end is connected to the bottom surface of the valve seat support seat 231. The center rod 233 is mounted at the center of the valve seat support seat 231. A circular groove 2311 is provided on the upper end surface of the valve seat support seat 231. A magnetic Iron, the height of the retaining edge of the circular groove 2311 is less than the thickness of the large end of the valve seat 400, the diameter of the circular groove 2311 is equal to the diameter of the large end of the valve seat 400 or is 1-2mm smaller than the diameter of the large end of the valve seat 400, and a valve seat positioning cone 2312 is provided on the valve seat support seat 231, the large diameter of the valve seat positioning cone 2312 is equal to the diameter of the valve port of the valve seat 400, and the upper end surface of the valve seat positioning cone 2312 is lower than the upper end surface of the valve seat 400.

[0031] During welding, the valve seat 400 is first passed through the center rod 233 and randomly placed in the circular groove 2311. Since the valve seat support seat 231 is provided with a valve seat positioning cone 2312, the valve seat can quickly find the center (quick positioning). Since a magnet is provided in the circular groove 2311, the valve seat 400 is further stabilized on the valve seat support seat 231 by using the magnet. At this time, the weight of the valve seat 400 is not enough to press down the hard spring 232.

[0032] Then, the upper bottle body 300 is randomly buckled onto the calibration bottom block 210. Similarly, the calibration bottom block 210 enables the upper bottle body 300 to quickly find the center (quick positioning). From the designed structure, it can be seen that the calibration bottom block 210, the center support column 220, the valve seat positioning cone 2312 and the center rod 233 are coaxially arranged. When buckled, when the upper bottle body 300 is not accurately centered, the valve seat 400 cannot pass through the through hole 310 of the upper bottle body 300. At this time, the upper bottle body 300 presses down the hard spring 232, and the operator manually moves the upper bottle body 300 to assist in alignment. After alignment, the valve seat 400 passes through the through hole 310 driven by elastic potential energy. When the valve seat 400 passes through the through hole 310 and is stable, the hard spring 232 has not recovered to its original length and is still in a compressed state. Therefore, the hard spring 232 firmly presses the valve seat 400 onto the upper bottle body 300;

[0033] After the above two parts are butted together, an automatic welding machine is used for welding. With the assistance of the auxiliary support seat, the welding connection between the valve seat 400 and the upper bottle body 300 will not deviate, and the quality of welding can be well guaranteed.

[0034] In summary, the utility model provides an auxiliary support seat for welding the tank body and the valve seat. During the operation, the operator can arbitrarily buckle the upper bottle body on the operating workbench, and buckle it above the calibration component, and quickly calibrate and quickly position the bottle body of the upper bottle body through the auxiliary calibration component: the calibration component includes a frustum-shaped calibration bottom block, wherein the calibration bottom block is frustum-shaped, so that the upper bottle body buckled on the calibration bottom block can automatically slide down and level along the inclined surface of the frustum, so as to realize the operation of rapid centering. At the same time, since the lower port surface of the upper bottle body abuts against the operating workbench, rather than The valve seat is in a suspended state, so the bottle body of the upper bottle body can be further calibrated to prevent the welded valve seat from being skewed due to the inclination of the bottle body during welding; the top elastic valve seat mounting assembly in the present invention is also provided with the same frustum positioning block, which can also perform center positioning and calibration on the valve seat to prevent deviation during welding, and the top elastic valve seat mounting assembly is provided with a magnet, which can play a certain stabilizing role on the valve seat, and the elastic design enables the top elastic valve seat mounting assembly to press the valve seat against the inner wall of the upper bottle body to assist the smooth progress of the welding operation.
