DETAILED DESCRIPTION

[0025] In order to better understand the present invention, the content of the present invention is further clearly set forth below in conjunction with the examples, but the protection content of the present invention is not limited to the following examples. In the following description, a large number of specific details are provided in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0026] like Figure 1 、 2 As shown, a valve body welding device includes a processing table 101, and a mounting groove 102 with an opening facing backward is provided on the rear side of the processing table 101 along the left and right directions. Because the mounting groove 102 opens backward, it can effectively prevent waste generated by welding from entering the mounting groove 102 and the bidirectional screw 114. A bidirectional screw 114 is rotatably provided in the mounting groove 102, and an adjusting motor 103 is provided on the mounting groove 102 for rotating the bidirectional screw 114. Both sides of the bidirectional screw 114 are screwed with mounting blocks 104 that are slidably connected to the mounting groove 102. A U-shaped mounting frame 105 is provided on the front side of the processing table 101, and mounting seats 107 that are slidably connected to the mounting frame 105 are provided on the two mounting blocks 104 respectively through mounting plates 106. A support seat 108 with an arc-shaped upper end is provided on the mounting seat 107. A vertical rod 109 is also provided on the processing table 101, and a top plate 110 is provided on the vertical rod 109, and a welding module is provided on the top plate 110. The bottom of the mounting seat 107 is also in sliding contact with the top of the processing table 101, so that the mounting seat 107 has just the right stability; the mounting seat 107 is also provided with a connecting sleeve 115 that is slidably connected to the mounting frame 105.

[0027] like Figure 1 、 2 As shown, the welding module includes a linear slide 201 arranged at the bottom of the top plate 110 and running in the left and right directions. A first telescopic push rod 202 is vertically arranged on the slide seat of the linear slide 201. A fixed plate 203 is arranged at the lower end of the output shaft of the first telescopic push rod 202, and a welding machine 204 is arranged on the fixed plate 203.

[0028] Based on the valve body's axial dimensions, a worker activates the adjustment motor 103, driving the bidirectional screw 114 to rotate, causing the two mounting blocks 104 to move left and right. The mounting blocks 104 then move the mounting plate 106 and mounting seat 107, adjusting the distance between the two support seats 108 to accommodate valves of varying axial dimensions. The valve body can then be placed on the two support seats 108, supported by the curved upper surfaces of the support seats 108.

[0029] After that, the valve body can be pressed and consolidated, and the welding machine 204 can be started to prepare for welding the valve body. After that, the slide of the linear slide 201 can be driven to move in the left and right directions, and the horizontal position of the welding machine 204 in the left and right directions can be adjusted. The output shaft of the first telescopic push rod 202 is driven to extend downward by a certain length, and the welding machine 204 is controlled to move up and down, thereby completing the welding process of the corresponding parts of the valve body; the valve body can then be rotated and adjusted so that the welding machine 204 can perform welding processing on other parts of the valve body.

[0030] After the welding process is completed, the valve body can be removed from the support seat 108 and the processing table 101.

[0031] According to another embodiment of the present invention, Figure 1 、 2 As shown, a guide insert 205 is vertically mounted on the slide seat of the linear slide 201 and is located at the side end of the first telescopic push rod 202. A guide insert 206 is also mounted on the fixed plate 203 and is plugged into the guide insert 205. During the welding process, the vertical plug-in connection between the guide insert 205 and the guide insert 206 ensures the stability and accuracy of the movement of the welding machine 204.

[0032] According to another embodiment of the present invention, Figure 4 、 5 As shown, vertical slots 311 are respectively provided on the left and right sides of the processing table 101 through support plates 314, and vertical plates 301 are slidably provided in the vertical slots 311. The bottom of the vertical slots 311 is screwed with an adjusting screw 312 that is rotatably connected to the bottom of the vertical plate 301. The bottom of the vertical plate 301 is rotatably connected to the upper end of the adjusting screw 312 through a first bearing. A twist handle 315 is provided on the adjusting screw 312. The vertical slots 311 are also provided with a handle that can be pressed against the vertical plate 301 to adjust the vertical slots 311 and the vertical plate 301. The locking bolt 313 is fixed at the connection of the plate 301, and a second telescopic push rod 302 is horizontally arranged on the vertical plate 301. The output shaft of the second telescopic push rod 302 is respectively provided with a connecting plate 303, and a connecting shaft 304 is rotatably provided on the connecting plate 303 through a second bearing. A pressing plate 305 is provided on the connecting shaft 304 for pressing the side end of the valve body. A driving module for rotating and driving the corresponding connecting shaft 304 is also provided on one vertical plate 301.

[0033] Before placing the valve body on the support seat 108 for welding, the output shaft of the second telescopic push rod 302 can be driven to extend a certain length, pushing the connecting plate 303 to move horizontally, so that the connecting shaft 304 and the pressing plate 305 on the connecting plate 303 move toward the direction close to the valve body until the pressing plate 305 presses against the side end of the valve body, thereby fixing the valve body; and in the process of welding, a connecting shaft 304 can be driven to rotate by the driving module, thereby driving the connecting shaft 304, the pressing plate 305 and the valve body on the other side to rotate, and then the rotation of the valve body can be conveniently adjusted, so that the welding machine 204 can weld the valve body more quickly.

[0034] If the central axis of the connecting shaft 304 is found to be not collinear with the central axis of the valve body, the locking bolt 313 can be loosened first, and the adjusting screw 312 can be adjusted by turning the handle 315 to drive the vertical plate 301 to slide vertically up and down on the vertical slot 311, thereby adjusting the extension and contraction of the vertical plate 301 in the vertical slot 311, thereby adjusting the vertical lifting and lowering of the connecting shaft 304. The locking bolt 313 can then be re-tightened and the connection between the vertical slot 311 and the vertical plate 301 can be reinforced. The vertical plate 301 is also provided with a receiving groove, and the vertical plate 301 is also provided with scale lines located in the receiving groove. The scale lines can be used to conveniently adjust the vertical position of the vertical plate 301, and the receiving groove can prevent wear on the scale lines.

[0035] According to another embodiment of the present invention, as shown in the figure, the drive module includes a drive motor 306 disposed on a riser 301, and a gear transmission assembly 307 is disposed between the output shaft of the drive motor 306 and the connecting shaft 304. Simply starting the drive motor 306 can drive the corresponding connecting shaft 304 to rotate through the gear transmission assembly 307.

[0036] According to another embodiment of the present invention, Figure 1 、 2 As shown, the bottom of support base 108 is provided with a fixing groove 111 that engages with mounting base 107. Fixing groove 111 is provided with a fixing bolt 112 for threading mounting base 107. Mounting base 107 is provided with a threaded fixing hole that is threaded with fixing bolt 112. By simply engaging fixing groove 111 with the mounting assembly, and then passing fixing bolt 112 through the side wall of fixing groove 111 and threading into the threaded fixing hole, support base 108 and mounting base 107 can be flexibly fixed. By simply separating fixing bolt 112 from the threaded fixing hole and releasing the connection between fixing groove 111 and mounting base 107, support base 108 can be removed and replaced. This makes it easier for users to maintain and replace support base 108 and also facilitates replacement of support base 108 that is compatible with the valve body, thereby providing more stable support for the valve body. Fixing bolt 112 is a hand-tightened bolt. The fixing bolt 112 can be conveniently adjusted by turning it without using tools, thereby quickly completing the assembly and disassembly of the mounting base 107 .

[0037] According to another embodiment of the present invention, Figure 1 As shown, the bottom of the processing table 101 is further provided with support legs 113. The support legs 113 can support the device.

[0038] According to another embodiment of the present invention, Figure 4As shown, a reinforcing plate 308 is further provided between the vertical groove 311 and the processing table 101, and both ends of the reinforcing plate 308 are respectively welded to the vertical groove 311 and the processing table 101. The reinforcing plate 308 can enhance the firmness of the connection between the vertical groove 311 and the processing table 101.

[0039] According to another embodiment of the present invention, Figure 4 、 5 As shown, a connecting plug 309 is fixed to the vertical plate 301, and a connecting rod 310 is fixed to the connecting plate 303, which is plugged into the connecting plug 309. The plug-in cooperation between the connecting plug 309 and the connecting rod 310 allows the connecting plate 303 to move horizontally more stably, and ensures that the connecting plate 303 remains stable after movement and adjustment, and prevents the second telescopic push rod 302 from being easily deformed and damaged.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
