[0026] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0027] The following is combined with Figure 1 ~Attached Figure 5 The embodiments of the present utility model are described in detail.

[0028] The present invention provides a positioning fixture for welding plate-shaped parts. The positioning fixture comprises: a positioning rod 1 extending vertically, a first bracket 2 extending front to back, and a second bracket 3 extending left to right. The positioning rod 1 is threaded and adapted to receive a first nut 4. It should be understood that the positioning rod 1 can be configured as a screw or a bolt with a cap at the bottom end. When the positioning rod 1 is configured as a screw, at least two first nuts 4 are required to be installed in corresponding first strip holes 5. When the positioning rod 1 is configured as a bolt, only one first nut 4 can be installed. There are multiple first brackets 2, distributed along the left-right direction. Each first bracket 2 is provided with a first strip hole 5 extending along the front-back direction for receiving the positioning rod 1. It should be understood that not every first bracket 2 requires receiving a positioning rod 1. There are two second brackets 3, distributed along the front-back direction. Each second bracket 3 is provided with a second strip hole 6 extending left to right. The front and rear ends of the first bracket 2 are respectively secured to the corresponding second strip holes 6 by bolts. It should be understood that the connection between the first bracket 2 and the second bracket 3 can be completed by installing bolts at the intersection of the first strip hole 5 and the second strip hole 6 .

[0029] The specific implementation method of the present invention is described below: align the holes of the plate-like parts with the positioning rod 1, and place the plate-like parts on the first bracket 2, so as to complete the positioning of the plate-like parts and carry out subsequent welding processing. When the plate-like parts that need to be welded are changed, the position of the positioning rod 1 can be adjusted according to the position of the holes of the new plate-like parts. Specifically, the front and rear positions of the positioning rod 1 can be adjusted along the length direction of the first strip hole 5, and the left and right positions of the first bracket 2 and the positioning rod 1 can be adjusted along the length direction of the second strip hole 6. In addition, the number of positioning rods 1 installed on the first bracket 2 can be increased or decreased according to actual needs. The present invention has a simple structure and low cost; it has better versatility and can be applied to the positioning of various plate-like parts with multiple holes; thus, it is convenient for staff to perform welding processing on plate-like parts, reduces the number of tooling, and helps to reduce the cost of welding processing.

[0030] Furthermore, the apparatus further comprises a diameter adjusting member 7; the diameter adjusting member 7 is cylindrical; the bottom of the diameter adjusting member 7 is provided with a threaded hole, which is threadedly connected to the positioning rod 1; the diameter adjusting member 7 is provided in multiple types, each with a different outer diameter. It should be understood that the holes in different plate-like parts, and the holes in different positions of the plate-like parts, may have different sizes; in this case, the diameter adjusting member 7 with the corresponding outer diameter can be installed to adapt to the hole of the plate-like part, thereby more accurately positioning the plate-like part.

[0031] Furthermore, a positioning hole 8 is provided on the top of the diameter adjusting member 7. Each type of diameter adjusting member 7 has a different positioning hole 8 having a different aperture. It should be understood that some plate-like components may have a small number of holes, or no holes, but may have a protrusion. In such cases, the positioning hole 8 on the top of the diameter adjusting member 7 can cooperate with the protrusion of the plate-like component to achieve positioning of the plate-like component.

[0032] Furthermore, the first strip-shaped hole 5 is configured as a countersunk hole, wider at the top and narrower at the bottom, to accommodate the first nut 4; the first nut 4 is hexagonal in structure; the upper wall of the first strip-shaped hole 5 limits the outer wall of the accommodated first nut 4. It should be understood that by making the diagonal length of the first nut 4 greater than the upper width of the first strip-shaped hole 5, the first strip-shaped hole 5 can limit the first nut 4; thereby, when the positioning rod 1 rotates, the first nut 4 is prevented from rotating with it, thereby facilitating installation and removal of the positioning rod 1.

[0033] Furthermore, it also includes a pressing mechanism, which includes a pressing rod 9 for pressing the plate-like part, a swing arm 10 for mounting the pressing rod 9, and a swing cylinder 11 for driving the swing arm 10 to rotate back and forth. It should be understood that the pressing mechanism is mainly used to keep the plate-like part fixed during welding.

[0034] Furthermore, the swing arm 10 is provided with a plurality of mounting holes 12 extending vertically along its length for mounting the pressing rod 9; the pressing rod 9 is threaded and adapted to receive a second nut 13. It should be understood that the pressing rod 9 can be selectively positioned in the mounting hole 12 according to actual conditions, and the height of the pressing rod 9 can be flexibly adjusted.

[0035] Furthermore, the lower section of the pressing rod 9 is covered with a flexible sleeve 14, forming a flexible layer at the lower end of the pressing rod 9. It should be understood that the lower end of the flexible sleeve 14 is closed; when the flexible sleeve 14 is placed over the lower section of the pressing rod 9, the bottom of the flexible sleeve 14 forms a flexible layer at the lower end of the pressing rod 9, thereby preventing damage to the surface of the plate-like component during pressing. The flexible sleeve 14 is typically made of rubber or elastic plastic.

[0036] Furthermore, it also includes: a base 15; the base 15 is provided with columns at the four corners, and each column is provided with a laterally extending connecting portion 16 at the top; the connecting portion 16 is provided with a connecting hole running through the top and bottom for installing the second bracket 3. It should be understood that the lower electrode can usually be installed on the base 15; and when the plate-like parts are positioned, the part to be welded corresponds to the lower electrode. According to actual conditions, the small parts to be welded can be placed on the lower electrode first, and then the plate-like parts; or the plate-like parts can be placed first, and then the small parts can be placed on the plate-like parts. Finally, the staff can complete the welding by holding a welding gun with an upper electrode and pressing it. Align the second strip hole 6 of the second bracket 3 with the connecting hole of the connecting portion 16, and tighten the bolts to complete the connection between the second bracket 3 and the connecting portion 16.

[0037] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
