[0044] The core of the present utility model is to disclose a special tool for right-angle welding positioning to improve the right-angle welding efficiency.

[0045] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0046] Combined with Figures 1 - 3 , the special tool for right-angle welding positioning disclosed by the present utility model is used to assist in performing right-angle welding on a first workpiece and a second workpiece, and includes a positioning base plate 100 and a positioning pressing member 200. A first positioning plate 110 and a second positioning plate 120 are vertically arranged on the positioning base plate 100. The first positioning plate 110 and the second positioning plate 120 respectively have a first positioning surface and a second positioning surface, and the first positioning surface and the second positioning surface are perpendicular. The first positioning surface and the second positioning surface are respectively used as the positioning references for the first workpiece and the second workpiece. The positioning pressing member 200 is movably arranged on the positioning base plate 100, and the positioning pressing member 200 has a first pressing surface and a second pressing surface respectively facing the first positioning surface and the second positioning surface.

[0047] Among them, when the positioning pressing member 200 moves to the first extreme position, the first pressing surface is spaced from the first positioning surface by a first preset distance, and the second pressing surface is spaced from the second positioning surface by a second preset distance; when the positioning pressing member 200 moves to the second extreme position, the first pressing surface is spaced from the first positioning surface by a third preset distance, and the second pressing surface is spaced from the second positioning surface by a fourth preset distance, and the first preset distance is greater than the third preset distance, and the second preset distance is greater than the fourth preset distance.

[0048] During the right-angle welding process, first, the first workpiece and the second workpiece are respectively attached to the first positioning surface and the second positioning surface, and the two are adjusted to the correct welding position. Then, the positioning pressing member 200 is moved in the direction from the first extreme position to the second extreme position until the first workpiece is pressed between the first pressing surface and the first positioning surface, and the second workpiece is pressed between the second pressing surface and the second positioning surface. At this time, the first workpiece and the second workpiece are positioned, and the first workpiece and the second workpiece can be welded.

[0049] Compared with the prior art, the special right-angle welding positioning tool disclosed by the utility model can assist in the right-angle welding of components. The right-angle arrangement of the first positioning surface and the second positioning surface can effectively ensure the right-angle welding dimensions and accuracy, thereby optimizing the welding process and ensuring the processing quality of the components. At the same time, the synchronous pressing of the first workpiece and the second workpiece by the positioning pressing member 200 can reduce the clamping times of the workpiece and greatly improve the processing efficiency. In addition, it also has the advantages of improving the service life of the workpiece, reducing the labor intensity of workers, and having strong versatility, being applicable to welding of various materials and angles.

[0050] Furthermore, a first buffer pad and a second buffer pad are respectively arranged on the surfaces of the first pressing surface and the second pressing surface. The first buffer pad and the second buffer pad are used to respectively fit with the first workpiece and the second workpiece to avoid damage to the workpiece surface when the positioning pressing member 200 presses the first workpiece and the second workpiece excessively.

[0051] Combined with Figure 1 and Figure 7 , the above-mentioned first pressing surface and second pressing surface can be a plane or a curved surface (exemplarily, the first pressing surface is a curved surface protruding towards the first positioning surface, and the second pressing surface is a curved surface protruding towards the second positioning surface).

[0052] Specifically, a transmission lead screw 300 is rotatably arranged on the positioning base plate 100 through a fixing member 310. The transmission lead screw 300 extends along the moving direction of the positioning pressing member 200, and the positioning pressing member 200 is arranged on the transmission lead screw 300.

[0053] In a specific embodiment disclosed by the utility model, combined with Figure 4 and Figure 5 , a transmission nut 330 is arranged on the transmission lead screw 300 in a transmission manner. An avoidance hole is formed on the positioning pressing member 200. The transmission lead screw 300 passes through the avoidance hole, and the transmission nut 330 is connected to the positioning pressing member 200. By rotating the transmission lead screw 300, the transmission nut 330 can drive the positioning pressing member 200 to reciprocate between a first extreme position and a second extreme position.

[0054] Among them, combined with Figure 4 ( Figure 4 the dotted part in Figure 5 is the transmission nut 330) and Figure 13, the above-mentioned fixing member 310 includes a bearing seat 311 and a bearing. The bearing seat 311 is arranged on the positioning base plate 100, and the bearing is arranged on the bearing seat 311. The transmission lead screw 300 passes through the inner ring of the bearing, so that the transmission lead screw 300 rotates relative to the bearing seat 311 and the positioning base plate 100 during the rotation process without position movement.

[0055] Combined with Figure 2 , since the above-mentioned fixing member 310 only provides a fixing point, in order to prevent the transmission lead screw 300 from tilting, the positioning pressing member 200 is arranged to fit with the positioning base plate 100 and is slidably arranged on the positioning base plate 100, so that the positioning pressing member 200 can be used as another supporting point for supporting the transmission lead screw 300.

[0056] In another specific embodiment disclosed by the present utility model, combined with Figure 8 , a threaded hole is formed on the fixing member 310. The positioning pressing member 200 is rotatably arranged at one end of the transmission lead screw 300, and the transmission lead screw 300 is in threaded cooperation with the fixing member 310. As the transmission lead screw 300 rotates, the transmission lead screw 300 drives the positioning pressing member 200 to move synchronously, realizing the movement of the positioning pressing member 200 between the first limit position and the second limit position. In this embodiment, the fixing member 310 can be a nut that is in threaded transmission cooperation with the transmission lead screw 300.

[0057] Furthermore, combined with Figure 9 and Figure 11 , in order to prevent the positioning pressing member 200 from rotating synchronously with the transmission lead screw 300, a sliding groove 101 is formed on the positioning base plate 100, and the sliding groove 101 extends along the moving direction of the positioning pressing member 200. A sliding protrusion 201 that is embedded in the sliding groove 101 and is slidably matched with the sliding groove 101 is formed at one end of the positioning pressing member 200 facing the positioning base plate 100. When the transmission lead screw 300 rotates, the positioning pressing member 200 rotates relative to the transmission lead screw 300 under the action of the sliding protrusion 201 and slides along the extending direction of the sliding groove 101.

[0058] In addition, a weight-reducing hole 102 for weight reduction is also formed on the positioning base plate 100. The position and shape of the weight-reducing hole 102 are not limited, as long as the normal function of the positioning base plate 100 is not affected.

[0059] In order to facilitate manual operation of the rotation of the transmission lead screw 300 by a person, a handwheel 320 is arranged at one end of the transmission lead screw 300 away from the first positioning plate 110 and the second positioning plate 120.

[0060] Furthermore, according to the actual situation, combined with Figure 1 and Figure 6, when there are differences in the thicknesses of the first workpiece and the second workpiece, the first preset distance and the second preset distance may be different. In one embodiment, in combination with Figure 12 , the positioning and pressing member 200 includes a main body 210 and a slider 220. An adjustment hole 211 is formed in the main body 210. The slider 220 is fixedly connected to the adjustment hole 211 in an adjustable manner through a bolt and can adjust its position. The first pressing surface and the second pressing surface as described above are respectively provided on the main body 210 and the slider 220. By adjusting the relative positions of the slider 220 and the main body 210, the relative magnitudes of the first preset distance and the second preset distance can be adjusted.

[0061] In one embodiment, the positioning base plate 100 is made of a steel plate and is a rectangular plate member. The first positioning plate 110 and the second positioning plate 120 are respectively welded to two adjacent side surfaces of the positioning base plate 100. The positioning and pressing member 200 is a member with a trapezoidal cross-section, and its two inclined surfaces serve as the first pressing surface and the second pressing surface respectively. By rotating the handwheel 320, the transmission lead screw 300 and the positioning and pressing member 200 can be driven to move synchronously, and the first workpiece and the second workpiece are respectively pressed against the first positioning plate 110 and the second positioning plate 120 to ensure the angle of the welded finished part.

[0062] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. The specific technical means in some embodiments can be partially or wholly incorporated into another embodiment on the premise that they are not explicitly excluded by another embodiment. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the broadest scope consistent with the principles and novel features disclosed herein.
