[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] When implementing: Figure 1-4 As shown, a pre-positioning device for welding hollow balls in a grid space structure comprises:

[0022] A positioning frame 1, wherein the cross-section of the positioning frame 1 is a cross and the surface of the positioning frame 1 is provided with evenly distributed mounting grooves;

[0023] A positioning structure 2, the positioning structure 2 is arranged on the top of the positioning frame 1;

[0024] Among them, the positioning structure 2 includes a lower pressure block 203 arranged on the inner side of the positioning frame 1, and an adjusting screw 202 is provided on the top of the lower pressure block 203. The upper end of the adjusting screw 202 passes through the positioning frame 1 and is provided with a knob 201. The adjusting screw 202 is threadedly connected to the inner wall of the positioning frame 1.

[0025] By rotating the knob 201, the adjusting screw 202 can be driven to gradually pass through the positioning frame 1, and then the lower pressing block 203 can be driven to be close to the surface of the hollow sphere to be welded. In this process, the installation groove can be used for the rod body of the grid space structure that needs to be welded on the surface of the hollow sphere to pass through. The setting of the installation groove can initially guide the rod body to facilitate the installation of the rod body, thereby facilitating subsequent welding work.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, an adsorption groove 204 is provided at the bottom of the lower pressing block 203 , and the lower pressing block 203 is made of rubber material.

[0027] An adjusting cavity 205 is defined inside the adjusting screw 202 . A slide plate 206 is slidably connected to the inner wall of the adjusting cavity 205 . A spring 208 is fixedly connected between the bottom of the slide plate 206 and the inner wall of the adjusting cavity 205 .

[0028] The spring 208 is used to maintain the position of the slide plate 206 under normal conditions. Figure 2 and Figure 3 At this time, the springs 208 are all in a stretched state.

[0029] An adjusting rod 207 is fixedly connected to the bottom of the slide plate 206 . The lower end of the adjusting rod 207 passes through the adjusting screw 202 and is fixedly connected to the top of the lower pressing block 203 .

[0030] A connecting channel is provided inside the adjusting rod 207 , and the adsorption groove 204 is connected to the connecting channel. A through hole 209 is provided on the surface of the adjusting rod 207 and is connected to the connecting channel.

[0031] When the adjusting screw 202 drives the lower pressure block 203 to move downward, the lower pressure block 203 can be first contacted with the surface of the hollow ball under the action of the spring 208. As the adjusting screw 202 gradually moves downward, the hollow ball will block the lower pressure block 203 and then drive the adjusting rod 207 to gradually insert into the interior of the adjusting cavity 205. In this process, the slide plate 206 can be driven to slide along the inner wall of the adjusting cavity 205, and at the same time, the spring 208 can be stretched. When the slide plate 206 moves upward, the space between the bottom of the slide plate 206 and the adjusting cavity 205 can be increased. Due to the arrangement of the through hole 209 and the connecting channel, the adsorption groove 204 can be connected to this part of the space through the connecting channel box through hole 209, and under the action of increasing the space between the bottom of the slide plate 206 and the adjusting cavity 205, suction can be generated by the adsorption groove 204 to be adsorbed on the surface of the hollow ball, thereby improving the positioning effect and preventing it from falling off during welding.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the surface of the positioning frame 1 is provided with evenly distributed connection holes 103 , the surface of the positioning frame 1 is provided with evenly distributed limiting screws 101 , and the surface of the limiting screws 101 is provided with nuts 102 .

[0033] According to the welding requirements, the limiting screw 101 is passed through two coaxially arranged connecting holes 103, and the position of the limiting screw 101 is limited after being threadedly connected to the limiting screw 101 through the nut 102. Repeat the above operation to install the other limiting screw 101. The rod body that needs to be welded on the hollow ball passes between the two limiting screws 101. At this time, the two limiting screws 101 cooperate with the installation groove to limit the rod body, so as to facilitate subsequent welding.

[0034] When the present invention is in use, the hollow ball to be welded is placed on the inner side of the positioning frame 1. During this process, the adjusting screw 202 can be driven to gradually pass through the positioning frame 1 by rotating the knob 201. Under the action of the spring 208, the lower pressing block 203 first contacts the surface of the hollow ball. As the adjusting screw 202 gradually moves downward, the hollow ball will block the lower pressing block 203 and then drive the adjusting rod 207 to gradually insert into the adjusting cavity 205. During this process, the slide plate 206 can be driven to slide along the inner wall of the adjusting cavity 205, and the spring 208 can be stretched. In the process of the slide plate 206 moving upward, the space between the bottom of the slide plate 206 and the adjusting cavity 205 can be increased. Due to the arrangement of the through hole 209 and the connecting channel, the adsorption groove 206 can be made 04 is connected to this part of the space through the through hole 209 of the connecting channel box, and under the effect of increasing the space between the bottom of the slide 206 and the adjusting chamber 205, it can generate suction through the adsorption groove 204 to adsorb on the surface of the hollow ball, thereby improving the positioning effect and avoiding falling off during welding. According to the welding requirements, the limiting screw 101 is passed through the two coaxially arranged connecting holes 103, and the position of the limiting screw 101 is limited after being threadedly connected to the limiting screw 101 through the nut 102, and then the above operation is repeated to install the other limiting screw 101. The rod body to be welded on the hollow ball passes between the two limiting screws 101. At this time, the two limiting screws 101 cooperate with the installation groove to limit the rod body, so as to facilitate subsequent welding.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
