First embodiment
Referring to fig. 1, a schematic structural view of a welding gap positioning device in a first embodiment is shown. As shown, the welding gap positioning device 100 in the present embodiment includes a positioning device main body 110 and a pushing portion 120. The boosting portion 120 includes a boosting rod 121, a first boosting handle 122 and a second boosting handle 123, and the first boosting handle 122 and the second boosting handle 123 are respectively and fixedly connected to two ends of the boosting rod 121. The push-aid rod 121 is provided with an external thread, the positioning device body 110 is provided with a threaded hole, and the push-aid rod 121 penetrates through the threaded hole and is in threaded connection with the threaded hole. The relative position between the push rod 121 and the positioning device body 110 can be adjusted by screwing or unscrewing the push rod 121 relative to the threaded hole.
The positioning device body 110 is provided with a positioning surface 111, and the positioning surface 111 is an inclined surface inclined with respect to a horizontal plane. The positioning surface 111 is further provided with a plurality of scale marks 1111, and each scale mark 1111 corresponds to a welding gap with different sizes. Specifically, the positioning device body 110 is positioned between two workpieces, and the height of the positioning surface 111 at the workpiece mounting positioning line indicates the size of the welding gap. Because the positioning surface 111 is an inclined surface, the height of each scale mark 1111 is different, and therefore when the positioning lines are assembled and aligned with different scale marks 1111, welding gaps with different sizes can be obtained. Preferably, the graduation marks 1111 extend from the positioning surface 111 to both side surfaces of the positioning device body 110 to facilitate alignment of the assembly positioning lines with the graduation marks.
Typically, the orientation surface 111 is angled from 10 to 30 degrees from horizontal. The welding gap positioning devices with different included angles can be selected according to requirements, if the required welding gap size is large, the welding gap positioning device with the large included angle can be selected, and if the required welding gap size is small, the welding gap positioning device with the small included angle can be selected.
Meanwhile, referring to fig. 2 to 3, a schematic structural view of the welding gap positioning device in the first embodiment after being placed on the first workpiece, and a schematic structural view of the welding gap positioning device and the first and second workpieces are respectively shown. An assembly positioning line 210 is drawn on the first workpiece 200, and two welding gap positioning devices 100 are respectively disposed at both ends of the first workpiece 200. The position of the positioning device body 110 is adjusted so that the assembly positioning line 210 is aligned with the graduation line 111 corresponding to the size of the required welding gap. The second workpiece 300 is then placed on the positioning surface 111 of the positioning device body 110 so as to be aligned with the graduation marks. Spot welding is then performed at the two spot welding areas 400 to fix the position between the first workpiece 200 and the second workpiece 300. Because the support and the position alignment of the welding gap positioning device are arranged, the two workpieces can meet the required welding gap very conveniently. After the spot welding is completed, the second push-aid handle 123 is rotated to move the push-aid rod 121 toward the second workpiece 300 until the first push-aid handle 122 abuts against the surface of the second workpiece 300. When the second push handle 123 is rotated, the positioning device body 110 moves away from the second workpiece 300 under the action of the first push handle 122, so as to separate from the welding region of the two workpieces.
As shown in fig. 1, a groove 112 is further formed at the bottom of the positioning device body 110, and a magnetic member is engaged in the groove 112. Generally, the workpieces to be welded are magnetic. In use, the magnetic member can be attached to the first workpiece 200 to prevent the position of the welding gap positioning device 100 from deviating from the assembly positioning line 210. Preferably, the magnetic member is an electromagnet, and when it is necessary to fix the welding gap positioning device 100 to the first workpiece 200, the electromagnet is energized, and the welding gap positioning device 100 is attracted to the first workpiece 200, and the positions of the two are relatively fixed. When spot welding between two workpieces is completed and the welding gap positioning device 100 needs to be removed, the electromagnet is powered off, and the adsorption between the welding gap positioning device 100 and the first workpiece 200 is released, so that the welding gap positioning device 100 is conveniently pulled out.
Since the friction between the positioning device body 110 and the first workpiece 200 is relatively large when the positioning device body is withdrawn from between the two workpieces, a wear-resistant layer is further disposed outside the positioning device body 110 to increase the wear resistance and prolong the service life of the positioning device body. Specifically, a wear-resistant layer may be sprayed or bonded on the outside of the positioning device body 110. Alternatively, the entire positioning device body 110 may be made of a wear-resistant material.
Second embodiment
This embodiment is an alternative embodiment of the first embodiment, and in this embodiment, the positioning device main body 110 is provided with a blind hole, and the blind hole is a threaded hole. The first assist grip 122 is provided only at one end of the assist lever 121 so as to abut against the second workpiece 300. The other end of the push-aid rod 121 is in threaded connection with the threaded hole. When the position of the push-aid portion 120 with respect to the positioning device body 110 needs to be adjusted, the portion of the push-aid rod 121 exposed from the screw hole may be directly rotated.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope of the present invention defined by the claims. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
