DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0025] The side frame 9 applied in this embodiment is a trapezoidal structure, which includes a front transverse plate 9-1 and a rear transverse plate 9-2 arranged in parallel, and two side plates 9-3 arranged at the ends of the front transverse plate 9-1 and the rear transverse plate 9-2, wherein the front transverse plate 9-1 and the rear transverse plate 9-2 are L-shaped strips with openings facing inwards, and the side plates 9-3 are U-shaped strips with openings facing inwards.

[0026] like Figure 1-3 As shown, a side frame 9 welding positioning tool comprises a support frame 1, and an inner longitudinal beam 2 and an inner cross beam 3 arranged in the support frame 1; a pad 4 and an L-shaped positioning block 5 with a positioning opening located on the inner side are installed on the support frame 1, and a plurality of F clamps 6 are arranged on the support frame 1; quick clamps 7 with clamping openings facing outwards are respectively arranged at both ends of the inner longitudinal beam 2, and a pad 4 corresponding to the quick clamp 7 and located on the support frame 1 is arranged on the outer side of the quick clamp 7.

[0027] In order to cooperate with the structure of the side frame 9, the support frame 1 is a trapezoidal structure, which includes a front crossbeam 1-1 and a rear crossbeam 1-2 arranged in parallel, and side beams 1-3 connected at both ends of the front crossbeam 1-1 and the rear crossbeam 1-2.

[0028] The inner longitudinal beam 2 and the inner cross beam 3 are provided to ensure the strength of the support frame 1. The inner cross beam 3 is also used to install the quick clamp 7. Therefore, at least one inner longitudinal beam 2 and at least one inner cross beam 3 are provided.

[0029] In this embodiment, one inner cross beam 3 is provided, and three inner longitudinal beams 2 are provided. Accordingly, six quick clamps 7 are provided and installed at both ends of each inner longitudinal beam 2 in a back-to-back arrangement.

[0030] The quick clamp 7 can be pressed against the bottom plates of the front transverse plate 9-1 and the rear transverse plate 9-2, thereby fixing the front transverse plate 9-1 and the rear transverse plate 9-2.

[0031] Since the side plate 9-3 of the rear cross plate 9-2 is an inclined plate with the upper end inclined outward, in order to ensure the accurate positioning of the rear cross plate 9-2, the L-shaped positioning block 5 located on the rear cross beam 1-2 has a positioning side surface of a positioning opening as a slope 5-1, and the upper end of the slope 5-1 is inclined outward.

[0032] In order to achieve accurate positioning of each component, at least one pad 4 is provided between two adjacent L-shaped positioning blocks 5 .

[0033] The F clamp 6 is used to fix various components. The F clamp 6 includes an L-shaped ruler rod 6-1 and a clamp rod 6-2 arranged on the ruler rod 6-1. The free end of the clamp rod 6-2 is installed with a screw rod 6-3 parallel to the vertical part of the ruler rod 6-1, and a presser foot 6-4 is arranged at one end of the screw rod 6-3 facing the horizontal part of the ruler rod 6-1.

[0034] The end of the transverse part of the ruler rod 6-1 is provided with a clamping plate 6-5 facing the direction of the screw rod 6-3, which is arranged opposite to the presser foot 6-4. The screw rod 6-3 and the clamping rod 6-2 are threadedly matched. By rotating the screw rod 6-3, the presser foot 6-4 can be driven to move toward or away from the clamping plate 6-5, thereby achieving the clamping or loosening of the parts.

[0035] Preferably, the end of the screw rod 6-3 where the pressure foot 6-4 is not provided is provided with a rotating rod 6-6 perpendicular to the screw rod 6-3 to facilitate the rotation of the screw rod 6-3.

[0036] Since the side panel 9-3 is a U-shaped strip with an opening facing inward, in order to fix it, the F clamp 6 matched with the side beam 1-3 is located on the inner side of the support frame 1, and the horizontal part of the ruler 6-1 of the F clamp 6 is located at the top.

[0037] The clamping plate 6-5 extends into the side plate 9-3 and presses on its bottom plate, and then the screw rod 6-3 is rotated to drive the presser foot 6-4 to move upward, thereby clamping it on the bottom surface of the support frame 1, thereby clamping and fixing the side plate 9-3.

[0038] In order to fix the front cross plate 9-1 and the rear cross plate 9-2, the F clamp 6 matched with the front cross beam 1-1 and the rear cross beam 1-2 is located on the outside of the support frame 1, and the clamp rod 6-2 of the F clamp 6 is located on the top.

[0039] In this embodiment, the quick clamp 7 is used to compress the middle part of the front transverse plate 9-1 and the rear transverse plate 9-2, and the F clamp 6 is used to fix the two ends of the front transverse plate 9-1 and the rear transverse plate 9-2.

[0040] In addition, since the welding point is located at the connection between two adjacent parts, that is, the ends of the front transverse plate 9-1, the rear transverse plate 9-2 and the side plate 9-3, the arrangement of the F clamp 6 here can also effectively avoid the problem of welding deformation.

[0041] Specifically, the clamping plate 6-5 of the F clamp 6 is attached to the bottom surface of the support frame 1, and then the screw rod 6-3 is rotated to drive the presser foot 6-4 to move downward, so that the presser foot 6-4 is pressed tightly against the bottom plate of the front cross plate 9-1 or the bottom plate of the rear cross plate 9-2, thereby ensuring the fixation of the end of the front cross plate 9-1 or the rear cross plate 9-2 and avoiding the problem of welding deformation.

[0042] The number and position of the F clips 6 are not limited to the above description and can be adjusted according to specific needs.

[0043] In order to support the support frame 1 , a column foot 8 is provided at the bottom of the support frame 1 .

[0044] When welding the side frame 9, the front transverse plate 9-1, the rear transverse plate 9-2 and the two side plates 9-3 are placed in the corresponding positions, that is, on the corresponding L-shaped positioning blocks 5 and the pads, and then the various components are fixed by the quick clamp 7 and the F clamp 6, and the welding operation can be performed at this time. The entire positioning process is fast and simple, which can ensure the verticality and parallelism of the components, avoid the problem of welding deformation, and has high welding efficiency and good finished product quality.

[0045] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
