Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a welding positioning mechanism for a metal box. Background Art

[0002] When processing a box structure, it includes a frame with an opening and an upper cover, the upper cover is installed on the opening, and the connecting ends between the upper cover and the opening are tightly welded by welding equipment, thereby achieving mutual fixation of the two. The existing positioning mechanism generally adopts a center positioning method to achieve automatic welding, that is, by setting a pressure block above the upper cover to fix its center, but it is found in actual processing that the structure will cause local deformation of the upper cover, which leads to the part between the opening and the upper cover being too large, affecting the sealing of the welding, so manual welding is required, affecting production efficiency. Utility Model Content

[0003] The main purpose of the utility model is to provide a welding positioning mechanism for a metal box, aiming to improve the existing welding positioning mechanism, which has a simple and stable structure and can effectively improve the welding sealing between the opening and the upper cover.

[0004] To achieve the above object, the utility model provides a welding positioning mechanism for a metal box, comprising:

[0005] A base, wherein two adjacent sides of the base are provided with positioning seats;

[0006] The sliding seat is arranged at a relative position of the positioning seat, the base is provided with a first lifting frame, the first lifting frame is provided with a first driving device, and the first driving device can drive the sliding seat to move toward the positioning seat.

[0007] The positioning seat and the sliding seat form a positioning groove;

[0008] A pressure seat is provided at the rear side of the positioning seat or between the positioning seat and the sliding seat. The pressure seat is provided with at least two pressure seats installed on a second driving device. The second driving device can drive the pressure seat to rotate or move vertically.

[0009] During the actual welding positioning, the frame is placed in the positioning groove, and then the first driving device drives the sliding seat to move, thereby positioning the frame and fixing it with the positioning frame as the reference point; then the upper cover is placed in the opening of the frame, and at the same time, the second driving device drives the pressing seat to rotate to the top of the upper cover, and at the same time, the pressing seat moves downward to fit the pressing seat.

[0010] During circumferential welding with the automatic welding device, the fit between the upper cover and the opening is achieved through the pressure seat. When the welding gun moves to the position of the pressure seat, the pressure seat rotates to avoid the welding gun, thereby avoiding excessive gap between the upper cover and the opening and ensuring stable pressing.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0018] like Figures 1 to 3 As shown, a welding positioning mechanism for a metal box comprises:

[0019] A base 1, wherein two adjacent sides of the base 1 are provided with positioning seats 11;

[0020] The sliding seat 12 is arranged at a relative position of the positioning seat 11. The base 1 is provided with a first lifting frame. The first lifting frame is provided with a first driving device 31. The first driving device 31 can drive the sliding seat 12 to move toward the positioning seat 11.

[0021] The positioning seat 11 and the sliding seat 12 form a positioning groove;

[0022] A pressure seat 2 is provided at the rear side of the positioning seat 11 or between the positioning seat 11 and the sliding seat 12. The pressure seat 2 is provided with at least two pressure seats 2 installed on a second driving device 32. The second driving device 32 can drive the pressure seat 2 to rotate or move vertically.

[0023] During the actual welding positioning, the frame is placed in the positioning groove, and then the first driving device 31 drives the sliding seat 12 to move, thereby positioning the frame and fixing it with the positioning frame as the reference point; then the upper cover is placed in the opening of the frame, and at the same time, the second driving device 32 drives the pressing seat 2 to rotate to the top of the upper cover, and at the same time, the pressing seat 2 moves downward to fit with the pressing seat 2.

[0024] During circumferential welding by the automatic welding device, the fit between the upper cover and the opening is achieved through the pressure seat 2.

[0027] Of course, a rotating device may be used in conjunction with a lifting device to achieve the same technical effect.

[0028] Specifically, a stopper 4 is provided below the sliding seat 12 to serve as a limit.

[0029] In the embodiment of the utility model, the first driving device 31 is provided with a guide rod which is integrally slidably arranged, and the guide rod is connected to the sliding seat 12 .

[0030] In the embodiment of the utility model, the bottom wall of the front part of the pressure seat 2 is provided with an adjustable positioning rod 5. In the actual design, the pressure seat 2 is preferably strip-shaped.

[0031] Specifically, the press seat 2 is provided with a threaded hole 51, the positioning rod 5 is provided with an external thread matched with the threaded hole 51, and the external thread is provided with a nut 52. This facilitates the height adjustment of the press seat 2, and when the product is different, it can be set according to actual needs, and with the structure of the positioning rod 5, the press seat 2 can adjust the angle during welding, and automatic welding of the welding gun can be achieved without moving.

[0032] In the embodiment of the utility model, the first driving device 31 is disposed on the second lifting frame 62 .
