Description

Technical Field

[0001] The utility model relates to the technical field of military product processing, in particular to an auxiliary welding frame and welding tooling for producing box support parts. Background Art

[0002] like Figure 3 As shown, the device is a support member used by the applicant to limit the position of products in a box for placing military supplies. The support member includes a bottom plate 11 that can be connected to the bottom of the box and a support frame arranged on the bottom plate 11. The support frame is used to support the product. The support frame includes two side panels 9 arranged side by side, two half support portions 8 and a plurality of full support portions 10. The two half support portions 8 are formed by cutting a full support portion 10 in half. The half support portions 8 and the full support portions 10 are arranged in an array on the upper end surfaces of the two side panels along the length direction of the side panels. The upper end surfaces of the side panels are in contact with the lower end surfaces of the half support portions 8 and the full support portions 10. The two half support portions 8 are arranged opposite to each other and all the full support portions 10 are located between the two half support portions 8.

[0003] During the processing, the upper end surface of the side panel 9 is welded to the lower end surface of the semi-supporting portion 8 and the full supporting portion 10, thereby processing into a support frame. However, during the processing, the semi-supporting portion 8 and the full supporting portion 10 are not easy to fix, and the welding position is easy to shift during the processing. The side panel 9 of the support frame is welded to the bottom plate 11, so that the support frame and the bottom plate 11 are processed into a support member. However, due to the long length of the weld between the support frame and the side panel 9, stress deformation is easily generated due to high temperature during the welding process. Therefore, in order to prevent the welding position of the side panel 9, the semi-supporting portion 8 and the full supporting portion 10 from shifting, and the support frame and the bottom plate 11 from stress deformation during welding, the applicant proposes an auxiliary welding frame and welding tooling for the production of box support members.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1 As shown, this embodiment provides an auxiliary welding frame for the production of box support parts. The box support parts include a base plate 11 and a support frame. The auxiliary welding frame provided in this embodiment is used to assist in the production of the support frame, so that the side plate part 9, the semi-support part 8 and the full support part 10 of the support frame are not prone to position displacement during welding.

[0023] The auxiliary welding frame provided in this embodiment includes two support uprights arranged side by side, and the two support uprights are fixedly connected by multiple groups of connecting parts. The spacing between the two support uprights is the same as the spacing between the two side panels 9. The two side panels 9 are abutted against the back sides of the two support uprights one by one, so as to ensure the position spacing of the two side panels 9. The two support uprights limit the position of the two side panels 9, and the upper end surfaces of the two support uprights can fully contact and support the lower end surfaces of the half support portion 8 and the full support portion 10 in the length direction. When the side panel portion 9, the half support portion 8 and the full support portion 10 are all placed, the upper end surface of the side panel portion 9 is in full contact with the lower end surfaces of the half support portion 8 and the full support portion 10, and their positions are limited and supported, so that they can be welded.

[0024] In this embodiment, the support vertical plate includes a rectangular portion 101 and a plurality of semicircular portions 102 arranged on the upper end surface of the rectangular portion 101 and arranged along the length direction thereof, and the outer circular side of the semicircular portion 102 is provided with a rectangular support portion 103 whose center line is perpendicular to the upper end surface of the rectangular portion 101. A support space having the same shape as the lower end surface of the full support portion 10 is formed between two adjacent semicircular portions 102 and the rectangular support portion 103 on the rectangular portion 101. The plurality of support spaces make the shape of the upper end surface of the support vertical plate consistent with the shape of the combined lower end surface of the semi-support portion 8 and the full support portion 10, so that the full support portion 10 and the semi-support portion 8 can be supported and limited, so that they are not easily moved.

[0025] In this embodiment, the number of connecting members is consistent with the number of semicircular portions 102 on the rectangular portion 101. The connecting members are all arranged at the semicircular portions 102. The connecting members are three connecting rods 2. In order to ensure the stability of the connection, the three connecting rods 2 are evenly distributed in a triangle between two opposite semicircular portions 102.

[0026] In this embodiment, the material of the supporting plate is a high temperature resistant material, specifically, high temperature resistant stainless steel. Meanwhile, the rectangular portion 101, the semicircular portion 102 and the rectangular supporting portion 103 are integrally formed.

[0027] Example 2

[0028] like Figure 2 As shown, the present embodiment provides a welding tool for producing box support parts, which is used for auxiliary processing of box support parts, and can reduce the position displacement of the side panel part 9, the semi-support part 8 and the full support part 10 of the support frame during welding, and can also avoid stress deformation during the welding process of the support frame and the side panel part 9.

[0029] The welding tool provided in this embodiment includes the auxiliary welding frame, welding table 3 and multiple groups of welding tables 3 in Example 1. The multiple groups of welding tables 3 are fixed to the welding table 3 and have crimping parts arranged in an array along the length direction thereof, and the spacing between two adjacent groups of crimping parts is 20-30 cm. In this embodiment, the auxiliary welding frame is located between the crimping parts and the welding table 3. During normal processing, the support frame is welded on the auxiliary welding frame. When the welding of the support frame is completed, the bottom plate 11 is placed on the two side plates 9 of the support frame, and pressure is applied to the bottom plate 11 and the side plates 9 through the crimping parts to prevent them from being deformed by stress due to high temperature during welding. Multiple groups of crimping parts are set because the bottom plate 11 and the side plates 9 are relatively long. In order to ensure the crimping effect, multiple groups are set.

[0030] In this embodiment, the crimping part includes a crimping plate 7 and two guide studs 5 arranged side by side on the welding table 3. The guide studs 5 are both screwed with positioning nuts 4. The crimping plate 7 is provided with through holes 6 that are inserted in cooperation with the two guide studs 5. Under normal circumstances, the guide studs 5 are not located in the through holes 6 of the crimping plate 7. Only when the base plate 11 and the support frame are welded, the two guide studs 5 are located in the through holes 6. When placing the crimping plate 7, the positioning nuts 4 are usually removed. After the crimping plate 7 is inserted in cooperation with the guide studs 5, the positioning nuts 4 are installed on the guide studs 5, and the height of the crimping plate 7 is limited by the positioning nuts 4.

[0031] During normal welding, the bottom plate 11 and the support frame are located between the crimping plate 7 and the welding platform 3. When the guide stud 5 between the positioning nut 4 and the welding platform 3 is located in the through hole 6, an extrusion space is formed between the crimping plate 7 and the welding platform 3. All the extrusion spaces are in the same plane and form a welding station for placing the auxiliary welding frame. By controlling the rotation of the positioning nut 4, the crimping plate 7 moves downward, and an extrusion force is applied to the bottom plate 11 and the support frame under the crimping plate 7, stress deformation due to high temperature during welding can be avoided.

[0032] In this embodiment, there are two ways to set the through holes 6 on the crimping plate 7. One method is a conventional setting, in which two through holes 6 corresponding to the guide studs 5 are opened on the crimping plate 7, so that the crimping plate 7 and the guide studs 5 are plugged in and out in coordination.

[0033] Another method is to have only one through hole 6 , and the through hole 6 is a long square hole, and the length of the through hole 6 is longer than the distance between the two guide studs 5 .

[0034] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
