[0026] Example

[0027] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides an auxiliary welding tool for the protective frame of an electric tricycle, including: a base plate 10, a plurality of positioning blocks 20, a plurality of positioning plates 21, and a plurality of fixing clamps 30. The base plate 10 is provided with a plurality of mounting grooves 101; a plurality of positioning blocks 20 are slidably installed in the plurality of mounting grooves 101 in a one-to-one correspondence; a plurality of positioning plates 21 are slidably installed on the plurality of positioning blocks 20 in a one-to-one correspondence, and slide toward the protective frame to be processed to abut against the side wall of the protective frame to locate the relative position between the protective frame to be processed and the base plate 10; each fixing clamp 30 has two clamping parts 31, and there is an angle between the two clamping parts 31, and the two clamping parts 31 respectively have a first accommodating space 32 and a second accommodating space 33 of adjustable size, and the protective frames to be processed are respectively inserted into the first accommodating space 32 and the second accommodating space 33 to fix the relative positions between the plurality of protective frames to be processed.

[0028] In this embodiment, if Figure 1 As shown, multiple positioning blocks 20 are slidably distributed along multiple installation grooves 101 to position the protective frames to be welded. During the welding process, the position of the positioning block 20 can be changed in real time so that the welding connection port is staggered with the positioning block 20, reducing the influence of the positioning block 20 on the welding connection port. The positioning plate 21 slides relative to the positioning block 20 to fine-tune the protective frame, further improving the accuracy of installation positioning, and cooperates with the fixing frame to preliminarily position and fix the protective frame. Figure 1 As shown, the angle between the two clamping parts 31 of the fixing clamp 30 can be 90°, and the protective frame to be welded is inserted into the first accommodating space 32 and the second accommodating space 33. The sizes of the first accommodating space 32 and the second accommodating space 33 are changed by adjusting the clamping part 31 to fix the relative position between the two protective frames to be welded, thereby further improving the installation accuracy, reducing positioning errors and installation steps, and improving the scope of application of the tooling.

[0029] Further, in some implementations of this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the positioning plate 21 includes: an abutment plate 211, a driving plate 212, a driving rod 214, and two guide posts 215. The driving plate 212 is provided with a rotary hole 213; the driving rod 214 is rotatably mounted in the rotary hole 213, the positioning block 20 is provided with a mounting hole 201, the driving rod 214 extends into the mounting hole 201, and slides relative to the inner wall of the mounting hole 201; the two guide posts 215 are installed between the abutment plate 211 and the driving plate 212, the positioning block 20 is provided with two guide holes 202, and the two guide posts 215 are slidably mounted in the two guide holes 202 in a one-to-one correspondence.

[0030] In this embodiment, if Figure 4 As shown, the driving rod 214 has a step surface, which abuts against the surface of the driving plate 212. The driving rod 214 and the mounting hole 201 are threadedly connected. The driving rod 214 is rotated, and the driving rod 214 is screwed into the mounting hole 201 along the axial direction. The step surface pushes the driving surface to slide along the axial direction of the driving rod 214, thereby driving the abutment plate 211 to abut against the side wall of the protective frame, thereby improving the installation accuracy.

[0031] Further, in some implementations of this embodiment, Figure 3 As shown, the abutment plate 211 and the driving plate 212 are respectively located on both sides of the positioning block 20. The driving plate 212 is slid to push the abutment plate 211 to abut against the side wall of the protective frame to be processed to locate the relative position between the protective frame to be processed and the substrate 10.

[0032] In this embodiment, if Figure 3 As shown, the drive plate 212 and the abutment plate 211 are respectively located on both sides of the guide column 215, the guide column 215 is inserted into the guide hole 202, and the drive plate 212 and the abutment plate 211 are respectively arranged on both sides of the positioning block 20, thereby increasing the adjustable range of positioning and thus increasing the scope of application.

[0033] Further, in some implementations of this embodiment, Figure 5 As shown, the plurality of mounting slots 101 are distributed along a plurality of preset directions.

[0034] In this embodiment, if Figure 5 As shown, the multiple preset directions include at least direction A and direction B, and the multiple installation grooves 101 can be distributed at intervals along direction A and direction B, thereby increasing the moving range of the positioning block 20 and further increasing the application range of the welding tooling.

[0035] Further, in some implementations of this embodiment, Figure 3 and Figure 4As shown, the welding tool also includes: a plurality of mounting blocks 203 and two elastic elements 204. The plurality of mounting blocks 203 are mounted on the positioning block 20 in a one-to-one correspondence, and the plurality of mounting blocks 203 are respectively engaged with the inner walls of the plurality of mounting grooves 101, and the plurality of mounting blocks 203 slide along the extension direction of the corresponding mounting grooves 101; the two elastic elements 204 are specifically springs, and the two guide holes 202 have step surfaces, and the two elastic elements 204 are mounted between the driving plate 212 and the step surfaces.

[0036] In this embodiment, if Figure 4 As shown, the cross section of the mounting block 203 is T-shaped, and the mounting groove 101 has the same cross-sectional shape as the mounting block 203 , which limits the sliding of the positioning block 20 to prevent the positioning block 20 from sliding out of the substrate 10 and failing.

[0037] Further, in some implementations of this embodiment, Figure 1 and Figure 2 As shown, the fixing clamp 30 further includes: a fixing rod 301, two fixing blocks 302, and two clamping blocks 303. The two clamping parts 31 are installed at both ends of the fixing rod 301; the two fixing blocks 302 are respectively installed at both ends of the fixing rod 301; the two clamping blocks 303 are slidably installed at both ends of the fixing rod 301, and a receiving space is formed between the clamping blocks 303 and the fixing blocks 302.

[0038] In this embodiment, if Figure 2 As shown, the fixing rod 301 is a bent rod, and there is an angle between the two bent parts. The angle between the two bent parts of the fixing rod 301 is the same as the angle between the two clamping parts 31, so as to improve the supporting strength of the fixing rod 301 for the protective frame to be welded. A threaded screw drive is adopted between the clamping block 303 and the fixing block 302 to improve the reliability of installation and fixation. An anti-slip pad is also arranged between the fixing block 302 and the protective frame to be welded to further improve the reliability and stability of installation and fixation.

[0039] In summary, when using an auxiliary welding tool for an electric tricycle protective frame, the protective frame to be welded is preliminarily positioned by sliding the positioning block 20 installed in the installation groove 101, the opening of multiple installation grooves 101 improves the overall application range of the tool, and the rotating drive rod 214 cooperates with the elastic element 204 to control the reciprocating sliding of the drive plate 212 and the abutment plate 211, and further fine-tunes the welding positioning of the protective frame to improve the accuracy of installation and positioning, and the protective frame to be welded is inserted into the first accommodating space 32 and the second accommodating space 33 at both ends of the fixing clamp 30, and the clamping block 303 is adjusted to move toward the fixing block 302 to abut against the two sides of the protective frame, and the protective frame is locked and fixed at the preset angle of the fixing rod 301, thereby reducing the installation steps of positioning and locking, and the installation grooves 101 distributed in multiple preset directions and the positioning block 20 in the sliding installation material installation groove 101 further improve the application range of the tool, and improve the installation efficiency and convenience.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
