They are detachable, easy to install and highly adaptable. They are designed to be manufactured in sections and pre-welded or spliced ​​on site to meet the transportation and installation requirements under complex working conditions. During the construction process, the welding quality of split tie rods is subject to extremely high standards. Not only is the weld strength required to meet the design requirements, but it is also necessary to ensure that the force at the joints of each part is uniform to prevent structural safety problems caused by welding deformation.

[0025] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-5 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] like Figure 1-5 As shown: This embodiment provides a split tie rod welding device, including a processing seat 100, a fixing assembly and a supporting assembly. Both sides of the processing seat 100 are connected to a fixing seat 101 by bolts. The middle of the top of the fixing seat 101 is a concave surface. The middle of the fixing seat 101 is slidably connected to a plurality of balls. The middle of the fixing seat 101 is slidably connected to a fixing frame 102. The bottom of the fixing frame 102 is provided with a fixing assembly. The fixing assembly includes a first spring 201, a clamping plate 202, a fixing plate 206, a second spring 207, a concave panel 205, a clamping plate 203 and a screw 204. The bottom of the fixing frame 102 The center is fixedly connected with a first spring 201, the bottom of the first spring 201 is fixedly connected with a clamping plate 202, the bottom surface of the clamping plate 202 is a concave surface, the bottom sides of the fixed frame 102 are fixedly connected with a fixing plate 206, the side of the fixing plate 206 close to the tie rod is fixedly connected with a second spring 207, the bottom of the second spring 207 is fixedly connected with a concave panel 205, the two ends of the fixed seat 101 are threadedly connected with a screw rod 204, the two ends of the bottom of the fixed frame 102 are fixedly connected with a clamping plate 203, and the bottom of the screw rod 204 is in contact with the top center of the clamping plate 203 of the adjacent fixed frame 102;

[0027] First, the operator places the two tie rods to be welded on the fixing seats 101 on both sides of the processing seat 100 respectively. The ball bearing allows the tie rod to slide and adjust smoothly along the middle of the fixing seat 101 with low friction. The concave design of the fixing seat 101 can place the tie rod more stably. When the fixing frame 102 moves downward under pressure, the clamping plate 202 and the concave panel 205 fit tightly against the surface of the tie rod. The concave design of the bottom surface of the clamping plate 202 ensures that the contact area with tie rods of different shapes or diameters is maximized, thereby enhancing the adaptability to tie rods of various specifications. By turning the screw 204, By precisely adjusting the height position of the fixing frame 102, the clamping plate 202 and the concave panel 205 can be fine-tuned according to the actual size of the tie rod and achieve an ideal tightening state. The clamping plate 203 cooperates with the screw 204 to effectively lock the position of the fixing frame 102 and ensure stability during the welding process. At the same time, the first spring 201 provides a basic clamping force to ensure that the clamping state can be maintained even under the thermal effect of welding, and the second spring 207 combines with the concave panel 205 to form a further clamping force, further enhancing the stability of the device in clamping different tie rods.

[0028] Support components such as Figure 1 , 5 As shown,

[0029] Two slide grooves 103 are provided on the top of the processing seat 100, and support components are arranged inside the slide grooves 103, which include a slider 301, a bracket 302, a support wheel 303, a bidirectional screw rod 304, a sprocket 305, a chain 306 and a motor 307. The sliders 301 are slidably connected to the adjacent slide grooves 103, and the tops of two adjacent sliders 301 located in different slide grooves 103 are fixedly connected to the same bracket 302, and the middle part of the bracket 302 is rotatably connected to a plurality of support wheels 303 arranged in an array, and the inner walls on both sides of the slide groove 103 are rotatably connected to the bidirectional screw rod 304, and the bidirectional screw rod One end of each of the two bidirectional screw rods 304 is fixedly connected with a sprocket 305, the center of each of the sprockets 305 is arranged to coincide with the center of each of the adjacent bidirectional screw rods 304, the middle of each of the sliders 301 is threadedly connected with the bidirectional screw rods 304, and the two sprockets 305 are connected by a chain 306. One side of the processing seat 100 is fixedly connected with a motor 307, and the output shaft of the motor 307 is fixedly connected to the middle of one end of the adjacent bidirectional screw rods 304. One side of the processing seat 100 is provided with a control switch group 106, and the input end of the control switch group 106 is electrically connected to the output end of the external power supply, and the input end of the motor 307 is electrically connected to the output end of the control switch group 106;

[0030] The operator starts the motor 307 by controlling the switch group 106. The output shaft of the motor 307 drives the bidirectional lead screw 304 on one side to rotate, and the bidirectional lead screw 304 drives the adjacent sprocket 305 to rotate. Due to the transmission effect of the sprocket 305 and the chain 306, the sprocket 305 and the bidirectional lead screw 304 on the other side also rotate in the same direction and synchronously. The rotation of the bidirectional lead screw 304 enables the slider 301 screwed thereto to synchronously move toward or away from the middle of the processing seat 100 along the direction of the lead screw axis in the slide groove 103, thereby achieving the position adjustment of the bracket 302 and the support wheel 303. When the two sets of support wheels 303 are close to each other, the bottom of the tie rod is lifted, and when they are away from each other, the tie rod is lowered, ensuring that no matter how the diameter of the tie rod changes, the support assembly can make the top of the support wheel 303 closely fit the surface of the tie rod, effectively ensuring that the middle of the tie rod is always level with the two ends during the welding process, preventing deformation or welding quality problems caused by uneven force.

Two symmetrically arranged limit columns 108, the bottoms of the limit columns 108 are fixedly connected to the tops of the processed parts, the tops of the limit columns 108 are slidably connected to the bottoms of the limit plates 107, a base 109 is fixedly connected to the bottom of one side of the processing seat 100, the top of the base 109 is fixedly connected to two symmetrically arranged telescopic columns 110, the telescopic ends of the telescopic columns 110 are fixedly connected to the bottom of the welding frame 104, and the input ends of the telescopic columns 110 are electrically connected to the output ends of the control switch group 106;

[0033] The operator controls the telescopic column 110 to synchronously perform corresponding extension or shortening actions through the control switch group 106, so that the welding frame 104 can be lifted and lowered vertically. At the same time, the welding gun 105 installed at the bottom of the welding frame 104 also adjusts its position synchronously, so as to realize accurate positioning and stable welding of tie rods of different diameters, lengths and different welding positions. The limit groove realizes smooth movement along the preset trajectory and plays a role of precise guidance, while the limit column 108 further enhances the stability of the welding frame 104 during the sliding process, ensuring that the welding frame 104 will not deviate or shake within the entire travel range.
