The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Referring to the accompanying drawings, Figures 1-10As shown, in the embodiment, a frame welding fixing tool includes a rack 1, the top end of the rack 1 is divided into two side welding areas 11, a head welding area 12 and a tail welding area 13, wherein the two side welding areas 11 are arranged symmetrically left and right, the head welding area 12 and the tail welding area 13 are arranged symmetrically front and back; a plurality of sets of pressing devices 2 for pressing and positioning each part of the frame 3 are installed on the side welding area 11, the head welding area 12 and the tail welding area 13 (for specific position distribution, please refer to Figure 6 As shown); the side welding area 11 is used for assembling the side support frame 31 of the frame 3 (setting two side welding areas 11 can realize simultaneous assembly of the two side support frames 31 of the frame 3, improving efficiency), the head welding area 12 is used for assembling the head support frame 32 of the frame 3, wherein after the side support frame 31 and the head support frame 32 are assembled, the side support frame 31 is adjusted to the placing posture of the side welding area 11, and the head support frame 32 is adjusted to the placing posture of the head welding area 12 (i.e. in a flat posture when assembling the side support frame 31 and the head support frame 32, please refer to Figure 3 、 5 As shown; when the overall assembly of the frame 3 is performed, the side support frame 31 and the head support frame 32 need to be adjusted to a vertical posture, please refer to Figure 7 As shown), the head support frame 32 is arranged between the two side support frames 31, and then the overall assembly of the frame 3 is performed, realizing the assembly welding and overall assembly welding of the parts of the frame 3 on the same welding fixing tool, reducing the initial investment cost, reducing the workload of the operator, and further improving the work efficiency.

[0023] Please refer to Figure 7 As shown, further, the tail welding area 13 is used for welding the tail cross rod 33 of the frame 3 between the two side support frames 31 when the overall assembly of the frame 3 is performed, the head welding area 12 is provided with a baffle 122 and a first-level spacing retaining piece 121, the baffle 122 is used for positioning the head support frame 32 in cooperation with the pressing device 2, and the first-level spacing retaining piece 121 is used for positioning the support structure of the head support frame 32 (please refer to Figure 4 and Figure 10 A), the side welding area 11 is provided with a second-level spacing retaining piece 111, the second-level spacing retaining piece 111 is used for positioning the support structure of the side support frame 31 (please refer to Figure 6 and Figure 10The vertical positioning member 131 is arranged on the tail welding area 13, and is used for positioning the assembly height of the tail cross rod 33. The first-level interval maintaining member 121 and the second-level interval maintaining member 111 are arranged, so as to ensure the stability of the structure of the side support frame 31 and the head support frame 32, and the welding precision. Similarly, the vertical positioning member 131 can ensure the accurate positioning of the tail cross rod 33 in each frame 3, and improve the product qualification rate.

[0024] It should be noted that, in the traditional frame 3 assembly welding, the operator needs to divide the frame 3 first, and then manufacture corresponding frame 3 welding fixing toolings according to the division result, such as a side frame 3 welding tooling, a front frame 3 welding tooling, a rear frame 3 welding tooling and a frame 3 overall welding tooling and the like. After the corresponding rod members are welded and assembled one by one through the toolings, overall assembly welding is performed, which is very inconvenient.

[0025] The specific working process of the welding fixing tooling in the embodiment is as follows: When the preliminary assembly welding is performed in the side welding area 11: the rod members constituting the side support frame 31 are placed around the second-level interval maintaining member 111 (the arrangement of the second-level interval maintaining member 111 can ensure the formation of the support structure of the side support frame 31 and improve the stability of the side support frame 31), and the top pressing devices 2 in the side welding area 11 are used for positioning the rod members, and then the operator welds and assembles the connecting portions of the rod members, so as to obtain two side support frames 31.

[0026] When the preliminary assembly welding is performed in the head welding area 12: the rod members constituting the head support frame 32 are placed around the first-level interval maintaining member 121 (to ensure the formation of the support structure of the side support frame 31), and one of the U-shaped long rods is arranged close to the baffle 122, the top pressing devices 2 in the head welding area 12 are used for positioning the rod members, and then the operator welds and assembles the connecting portions of the rod members, so as to obtain the head support frame 32.

[0027] During the overall assembly and welding of the frame 3: the two side support frames 31 and the head support frame 32, after being processed and assembled, are adjusted to an upright position and placed one-to-one on the side welding area 11 and the head welding area 12. The head support frame 32 is made to be tightly attached to the baffle 122, and one end of each of the two side support frames 31 is made to be tightly attached to both sides of the head support frame 32. Then, the top pressing devices 2 in the side welding area 11, in conjunction with the secondary spacer retainer 111, apply constant pressure to the side support frames 31. Positioning: The rear crossbar 33 is placed on the vertical positioning piece 131 of the rear welding area 13 to provide accurate vertical positioning. After the two ends of the rear crossbar 33 are pressed against the other ends of the two side support frames 31, the pressing devices 2 in the rear welding area 13 press and fix the rear crossbar 33. The operator welds the joints of the front support frame 32, the side support frames 31 and the rear crossbar 33 that are pressed against each other, thereby completing the overall assembly welding and obtaining the frame 3.

[0028] See appendix Figure 1 , 8 As shown in Figure 9, further, the pressing device 2 includes a mounting frame 21, a base 22, a handle 23, a pressing rod 24, and at least one, preferably two, connecting members 25. The mounting frame 21 is mounted on the frame 1, and the base 22 is mounted on the top of the support member. One end of the base 22 has a rotating part 221, and the other end has a guide part 222. The rotating part 221 is rotatably connected to one end of the handle 23. The guide part 222 is used to relatively restrict the movement direction of the pressing rod 24, ensuring that the pressing rod 24 can reciprocate along the guide part 222 (i.e., restricting the pressing rod 24 to reciprocate only in one direction). The pressing rod 24 is used to cooperate with the frame 1 to press and fix the frame 3. The two ends of the connecting member 25 are rotatably connected to the rotating end of the handle 23 and the connecting end of the pressing rod 24 respectively by pre-set screws. An adjustable top-pressure bolt 241 is installed on the top-pressure end. The top-pressure bolt 241 is used to further adjust the pressure of the top-pressure end. That is, when the top-pressure device 2 presses and fixes the side support frame 31, the head support frame 32 and the tail crossbar 33 or the rods that make up the side support frame 31 and the head support frame 32, some rods may have bending, dents or bulging on some surfaces due to tolerance, transportation bumps and other factors. Under the premise that it is determined that the rods with the above phenomena can be processed and the quality of the welded finished product after processing is not lower than the quality of the normal finished product, for the parts of the rods with the above phenomena, the top-pressure bolt 241 on the top-pressure end of the top-pressure rod 24 can be rotated to make the top-pressure bolt 241 relatively closer to or farther away from the rod to be fixed, thereby achieving stable positioning of the rods and improving the accuracy of subsequent welding.

[0029] It should be noted that the connection between the handle 23 and the rotating part 221 is a fixed point, and the connection between the handle 23 and the connecting piece 25 is a movable point rotating around the fixed point. When the handle 23 moves close to the position of the pressing rod 24, the connection between the handle 23 and the connecting piece 25 (movable point) rotates around the connection between the handle 23 and the rotating part 221 (fixed point), synchronously driving the pressing rod 24 to extend, thereby realizing the locking function of the pressing device 2. When the handle 23 moves away from the position of the pressing rod 24, the connection between the handle 23 and the connecting piece 25 (movable point) rotates in the opposite direction around the connection between the handle 23 and the rotating part 221 (fixed point), synchronously driving the pressing rod 24 to retract, thereby realizing the unlocking function of the pressing device 2.

[0030] Referring to the accompanying drawings Figure 1 As shown, the welding fixture further includes four moving rollers 4 arranged at the bottom end of the rack 1. The moving rollers 4 are used to provide the rack 1 with a moving function. The operator can select the moving rollers 4 or add a limiting device to the moving rollers 4 according to the actual situation to ensure that the rack 1 is limited when moving to the processing destination, so that the rack 1 is in a relatively stable state for welding processing, thereby improving the processing accuracy.

[0031] The above-described embodiments are merely preferred embodiments of the present application, and do not limit the present application in any form. Any skilled person in the art can make more possible changes and decorations, or modifications to the technical solutions of the present application without departing from the scope of the present application, using the disclosed technical content. Therefore, any equivalent changes and modifications made according to the ideas of the present application without departing from the technical solutions of the present application shall be covered within the protection scope of the present application.
