Description

Technical Field

[0001] The present invention relates to the technical field of welding processing, in particular to a spot welding device for a ski board and the ski board. Background Art

[0002] A sled is installed on the front wheel of the sled for easy use in snowy areas. However, the current sled lacks a steering system, and the sled has a large body tilt angle during steering, making it prone to overturning.

[0003] Currently, spot welding of ski decks is often performed manually by workers. This method is time-consuming and labor-intensive, significantly increasing the workload of workers. Workers are prone to fatigue after long hours of work, which affects the quality of the spot welding of the ski decks.

[0077] The second feeding mechanism 6 is correspondingly provided on both sides of the branch pipe 408;

[0078] The second feeding mechanism 6 includes an electric telescopic column 601 fixedly connected to the top plate 401, the output end of the electric telescopic column 601 is fixedly connected to the cylinder 602, the two ends of the cylinder 602 are respectively electrically connected to the cylinder rod 603 of the connecting port of the adapter connector 102, and the lower side of the cylinder 602 is fixedly connected to the pad 604 that is adapted to the plug-in connector 102.

[0079] The working principle of the present invention is as follows:

[0080] The flat plate 301 can be adapted for overlapping the steering member 104. At the same time, the opposite surfaces of the side platforms 302 at both ends are inclined and adapted to fit the steering member 104. When the steering member 104 is manually snapped onto the flat plate 301, the steering member 104 can automatically slide into position in accordance with the inclined surfaces of the side platforms 302. Similarly, the inverted beam 101 that is adapted to be placed between the two base mechanisms 3 can automatically slide into position by fitting the protruding ends of the inclined plates 304. No manual alignment is required, thereby improving the convenience of manually placing the beam 101 and the steering member 104.

[0081] By connecting two base mechanisms 3, using the flat plate 301 and the side platform 302 adapted on the base mechanism 3 to place the steering member 104, and using the gap between the two base mechanisms 3 and the fit of the inclined plate 304 to place the beam 101, and making the connecting ports of the beam 101 and the steering member 104 face each other, the beam 101 and the steering member 104 on one plate group mechanism 1 are staggered and placed on the base mechanism 3, saving the space required for spot welding and saving the installation cost of the device.

[0082] The setting of the inclined plate 304 can not only adapt to the placement of the beam 101, but also the fitting support of the inclined plate 304 corresponds to the welding point of the beam 101, thereby effectively providing support stability during the welding process and improving welding quality.

[0083] After the crossbeam 101 and the steering member 104 are placed on the base mechanism 3, the base mechanism 3 is placed in such a manner that the connection ports of the crossbeam 101 and the steering member 104 are facing each other. The first rail column 205 is slid along the second electric rail 204 to insert the positioning rod 206 into the connection port of the crossbeam 101 and the steering member 104. On the one hand, it provides support for subsequent welding, and on the other hand, it can detect whether the connection port of the plate group mechanism 1 is accurately processed, thereby improving the welding accuracy.

[0084] After a base mechanism 3 moves to the spot welding assembly position, the pushing assembly of the first feeding mechanism 5 adsorbs the connecting pipe 105 and slides it along the fourth electric rail 501 toward the steering member 104, and the connecting pipe 105 is sent to the welding position. The connecting piece 102 supported by the cylinder 602 is moved toward the beam 101 by extending the electric telescopic column 601, and the connecting piece 102 is sent to the welding position. Then, all points are welded at one time by the first welding head 407 and the second welding head 410, so as to perform efficient spot welding and improve the spot welding processing speed.

[0085] By relative positioning of the base mechanism 3 and the spot welding assembly, the first feeding mechanism 5 and the second feeding mechanism 6 are used to transport the pipe 105 and the connecting piece 102 respectively, and then the welding mechanism 4 is used to adapt the welding points for electric welding, so that manual work can be kept away from the welding point during welding, thereby improving the safety of spot welding work.

[0086] After the plate group mechanisms 1 on the two base mechanisms 3 are welded, the base mechanisms 3 are slid along the bottom plate mechanism 2 completely away from the positioning assembly, so that the welded plate group mechanism 1 can be removed from the other side of the positioning assembly, and a new crossbeam 101 and steering member 104 are installed at the same time. Therefore, the plate group mechanism 1 can be installed on both sides of the spot welding assembly, thereby improving the filling speed of the spot welding device.

[0087] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
