Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically to a multi-angle welding device for stainless steel pipes. Background Technology

[0002] Multi-angle welding equipment for stainless steel pipe fittings is a specialized device designed specifically for stainless steel pipe fittings, enabling multi-angle, high-precision welding. It typically consists of a welding host, control system, positioning device, clamping mechanism, welding torch, and cooling system. The welding host is the core component, providing the energy and power required for welding; the control system handles the automated and intelligent control of the equipment; the positioning device and clamping mechanism ensure the stability and accuracy of the pipe fittings during welding; and the welding torch converts electrical energy into heat energy to achieve weld fusion.

[0003] For example, Chinese patent CN214185953U, entitled "A Stainless Steel Pipe Welding Equipment", includes a housing, a column, a welding device, a motor, a reducer, a stabilizing sleeve, a fixing block, a cover, a fixing plate, and a control panel. The housing has a processing chamber inside. The column is installed on the top left side of the housing. The column has an operating chamber inside and a moving device inside. The welding device is installed on the moving device. The motor and reducer are both installed at the top of the processing chamber, and the output end of the motor is connected to the input end of the reducer. A bearing is installed in the middle of the top of the housing. The stabilizing sleeve is installed at the top of the housing. The output end of the reducer passes through the bearing and the stabilizing sleeve and is connected to the bottom end of the fixing block. The fixing block is located inside the stabilizing sleeve and is rotatably connected to the stabilizing sleeve.

[0004] While the existing technologies can achieve pipe welding, in practical use, the welding equipment is not very effective. Operators usually need to rotate the pipe to make the welding head weld around it, which increases their workload. Furthermore, it is difficult to adjust the angle of the welding mechanism. The welding mechanism is usually fixed with bolts, which means that the bolts need to be removed and reinstalled before the angle can be adjusted, thus reducing the flexibility of the welding mechanism. Therefore, it does not meet the current needs. In response, we have proposed a multi-angle welding equipment for stainless steel pipes. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle welding device for stainless steel pipe fittings, so as to solve the problems of poor performance of the welding device mentioned in the background art and the difficulty in adjusting the angle of the welding mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle welding equipment for stainless steel pipe fittings, including a welding table, on both sides of the upper end of the welding table, a second mounting frame is fixedly installed, a transmission cavity is provided inside the welding table below the second mounting frame, the transmission cavity is a through structure, a drive gear is provided inside the transmission cavity, a rotating disk is provided inside the second mounting frame, the rotating disk is rotatably connected to the second mounting frame, and a toothed ring is fixedly installed outside the rotating disk, the toothed ring meshing with the drive gear.

[0007] Preferably, a second motor is fixedly installed inside the welding station on one side of the transmission cavity, and the output shaft of the second motor extends into the transmission cavity and is fixedly connected to the drive gear.

[0008] Preferably, a first mounting bracket is fixedly provided at the center of the upper end of the welding platform, and a connecting seat is provided below the first mounting bracket. The connecting seat has a drive cavity inside, which is an open structure. A welding mechanism is provided inside the drive cavity. A first motor is fixedly provided inside the front and rear ends of the connecting seat at both ends of the drive cavity. The output shaft of the first motor extends into the drive cavity and passes through the welding mechanism.

[0009] Preferably, hydraulic telescopic devices are fixedly installed at both the front and rear ends of the upper end of the first mounting frame, and the telescopic ends of the hydraulic telescopic devices extend to the lower part of the first mounting frame and are fixedly connected to the connecting seat.

[0010] Preferably, rotating cylinders are fixedly installed on both sides of the outer side of the rotating disk. One end of the rotating cylinder extends to the outside of the second mounting bracket, and the second mounting bracket is rotatably connected to the rotating cylinder. Threaded holes are provided inside the front and rear end side walls of the rotating cylinder. Bolts are installed inside the threaded holes. One end of the bolt extends into the inside of the rotating cylinder. A clamping plate is provided at the end of the bolt located inside the rotating cylinder, and the clamping plate is rotatably connected to the bolt.

[0011] Preferably, a limiting ring is provided on the outer sleeve of the rotating drum on one side of the threaded hole, and the limiting ring is fixedly connected to the rotating drum.

[0012] Preferably, support rods are fixedly installed at the four corners of the lower end of the welding table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model enables the pipe to rotate through the gear ring and the drive gear. When the pipe is being welded, the welding mechanism is adjusted to a suitable position. At this time, the second motor is turned on, so that the output shaft of the second motor drives the drive gear to rotate. The drive gear drives the gear ring that meshes with it to rotate. At this time, the gear ring enables the rotating disk and the rotating drum to rotate slowly and uniformly on the second mounting frame. At the same time, the pipe fixed inside the rotating drum rotates together with the rotating drum. As the rotating drum rotates, the welding mechanism performs welding operations around the pipe, thereby improving the convenience of pipe welding.

[0015] (2) This utility model can adjust the angle of the welding mechanism through the drive cavity and the first motor. Before welding the pipe, the pipe has been fixed. At this time, the first motor is turned on, so that the output shaft of the first motor drives the welding mechanism to rotate inside the drive cavity until the welding mechanism is rotated to a suitable angle. At this time, the hydraulic telescopic device is turned on, so that the telescopic end of the hydraulic telescopic device extends. Through the extension of the telescopic end of the hydraulic telescopic device, the connecting seat and the welding mechanism move downward together until the welding mechanism is moved to a suitable position. Then the welding operation is carried out, thereby improving the flexibility of the angle adjustment of the welding mechanism.

[0016] (3) This utility model can fix the pipe fittings by means of bolts and clamping plates. Before welding the pipe fittings, the two pipe fittings are passed through the rotating cylinders on both sides until the two pipe fittings come into contact with each other. At this time, the operator rotates the bolts on both sides at the same time, so that the bolts move in the threaded holes through the threads. At the same time, the bolts drive the clamping plates to move closer to the pipe fittings until the clamping plates come into contact with the pipe fittings and cause compression, thus completing the fixing of the pipe fittings and avoiding the pipe fittings from shifting position under external interference, thereby improving the welding accuracy of the pipe fittings.

A second mounting bracket 9 is fixedly installed on both sides of the upper end of the welding table 1. A limiting ring 13 is sleeved on the outside of the rotating drum 14 located on one side of the threaded hole 19. The limiting ring 13 is fixedly connected to the rotating drum 14. Support rods 2 are fixedly installed at the four corners of the lower end of the welding table 1.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The welding station 1 is located below the second mounting frame 9 and has a transmission cavity 10 inside. The transmission cavity 10 is a through structure and has a drive gear 17 inside. The second mounting frame 9 has a rotating disk 11 inside and is rotatably connected to the second mounting frame 9. A gear ring 12 is fixedly installed on the outside of the rotating disk 11 and meshes with the drive gear 17. A second motor 18 is fixedly installed inside the welding station 1 on one side of the transmission cavity 10. The output shaft of the second motor 18 extends into the transmission cavity 10 and is fixedly connected to the drive gear 17, so as to drive the pipe to rotate through the drive gear 17 and the gear ring 12.

[0025] Please see Figure 1 and Figure 3 A first mounting bracket 3 is fixedly installed at the center of the upper end of the welding table 1. A connecting seat 5 is installed below the first mounting bracket 3. A drive cavity 7 is installed inside the connecting seat 5. The drive cavity 7 has an open structure and a welding mechanism 6 is installed inside the drive cavity 7. A first motor 8 is fixedly installed inside the front and rear ends of the connecting seat 5. The output shaft of the first motor 8 extends into the drive cavity 7 and passes through the welding mechanism 6. A hydraulic telescopic device 4 is fixedly installed at the front and rear ends of the upper end of the first mounting bracket 3. The telescopic end of the hydraulic telescopic device 4 extends to the lower end of the first mounting bracket 3 and is fixedly connected to the connecting seat 5, so as to facilitate the adjustment of the angle of the welding mechanism 6 by the first motor 8.

[0026] Please see Figure 1 and Figure 4 Rotary cylinders 14 are fixedly installed on both sides of the outer side of the rotating disk 11. One end of the rotating cylinder 14 extends to the outside of the second mounting bracket 9, and the second mounting bracket 9 is rotatably connected to the rotating cylinder 14. Threaded holes 19 are provided inside the front and rear end side walls of the rotating cylinder 14. Bolts 15 are installed inside the threaded holes 19. One end of the bolt 15 extends into the interior of the rotating cylinder 14. A clamping plate 16 is provided at the end of the bolt 15 located inside the rotating cylinder 14. The clamping plate 16 is rotatably connected to the bolt 15. The rotating cylinder 14 is connected to the rotating disk 11, which facilitates clamping and fixing of the pipe fittings through the clamping plate 16.

[0027] Working principle: In use, first, pass the two pipe sections through the rotating drums 14 on both sides until the two pipe sections contact each other. At this time, the operator simultaneously rotates the bolts 15 on both sides, causing the bolts 15 to move through the threaded holes 19. At the same time, the bolts 15 drive the clamping plate 16 to move closer to the pipe until the clamping plate 16 contacts the pipe and causes compression. Then, the first motor 8 is turned on, causing the output shaft of the first motor 8 to drive the welding mechanism 6 to rotate inside the drive cavity 7 until the welding mechanism 6 is rotated to a suitable angle. At this time, the hydraulic telescopic device 4 is activated, causing the telescopic end of the hydraulic telescopic device 4 to extend... The extension of the hydraulic telescopic device 4 drives the connecting seat 5 and the welding mechanism 6 to move downward together until the welding mechanism 6 is moved to a suitable position. At this time, the second motor 18 is turned on, so that the output shaft of the second motor 18 drives the drive gear 17 to rotate. The drive gear 17 drives the gear ring 12 that meshes with it to rotate. At this time, the gear ring 12 enables the rotating disk 11 and the rotating drum 14 to rotate slowly and uniformly on the second mounting frame 9. At the same time, the pipe fixed inside the rotating drum 14 rotates together with the rotating drum 14. As the rotating drum 14 rotates, the welding mechanism 6 performs welding operations around the pipe.
