Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, and in particular to a welding positioning device for frame products. Background Technology

[0002] In frame-type products such as metal pallets, the components are typically connected by welding. Besides ensuring welding quality, the relative positions of the components must also be guaranteed. For example, the relative position between the pallet legs and the pallet panel is required for forklift entry, pallet stacking, conveyor belt transport, and automated warehouse storage. The pallet panels are all fixed to the legs by welding.

[0003] When metal pallets and other frame-type products are mass-produced, the relative positions of each component are ensured by positioning elements. Positioning elements come in various forms and are generally fixed to a welding stand by welding. When the frame to be welded has a structural requirement of layered and staggered arrangement, this positioning method can cause the welded parts to collide with, interfere with, get stuck, or even become difficult to remove from the positioning elements. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides a welding positioning device for frame products, aiming to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides a welding positioning device for frame products, comprising: a positioning seat, the positioning seat including a fixing part and a limiting part, and a limiting mechanism provided on the limiting part of the positioning seat, the limiting mechanism including a limiting rod and a limiting block, the limiting rod being arranged parallel to the limiting part of the positioning seat, and the limiting rod being movably connected to the positioning seat, and the limiting block being arranged on the limiting end of the limiting rod.

[0006] The positioning seat is the main body of this device, divided into a fixing part and a limiting part according to their corresponding functions. The fixing part is designed to install the positioning seat at the designated position on the external welding bracket, while the limiting part is designed to fix the frames together. In use, this device is used in pairs. The movable connection between the limiting rod and the positioning seat ensures the movement performance of the limiting block, thereby ensuring that the workpiece is easily removed without interference or jamming.

[0007] Preferably, the width of the fixing part of the positioning seat is smaller than the width of the positioning seat, forming a fixing base surface, and two internal thread type fixing holes are preset at equal intervals on the fixing base surface.

[0008] The design of the fixed base surface is intended to ensure a tight fit between the positioning seat and the external welding bracket. The design of the internal threaded fixing hole makes it easy for workers to insert bolts to fix the positioning seat and the external welding bracket, thereby ensuring the stability of the connection.

[0009] Preferably, two sets of limiting rods and limiting blocks are provided, and the limiting rods in the two sets are corresponding to positioning pins and top rods, and the limiting blocks in the two sets are corresponding to limiting posts and limiting plates.

[0010] The positioning seat has a pre-set groove, and the position of the groove corresponds to the installation position of the limiting post and the limiting plate. In use, the positioning pin is used with the limiting post, and the push rod is used with the limiting plate. The position of the limiting post on the positioning pin and the thickness of the limiting plate can be selected according to the relative size of the parts to be welded, avoiding limitations for the user.

[0011] Preferably, the positioning pin and the push rod are provided with a handle on the side away from the limiting block.

[0012] The handle is fixed at an appropriate angle to the other end of the positioning shaft and the push rod according to the position of the limiting pin and the limiting plate. This method is common knowledge in the field, so it will not be described in detail. Moreover, the handle, the positioning pin and the push rod are integrally formed, thus ensuring the stability of their connection.

[0013] Preferably, a clearance hole is pre-set at the connection between the limiting rod and the positioning seat limiting part, and a compression spring connected to the limiting rod is pre-set inside the clearance hole.

[0014] This design allows compression springs to be installed on both the positioning shaft and the push rod, and the entire assembly is installed inside the clearance hole. Under the preload of the compression springs, the limiting post and the limiting plate are completely sunk into the groove of the positioning seat.

[0015] The beneficial effects of this utility model are:

[0016] The movable connection between the limiting rod and the positioning seat ensures the movement performance of the limiting block, thereby ensuring that the workpiece is removed without interference or jamming. The device is simple to operate, easy to use, and reliable in positioning, which can guarantee product requirements and thus facilitates its widespread use. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Please see Figures 1 to 5This utility model provides a welding positioning device for frame products, including: a positioning seat 1, which includes a fixing part and a limiting part, and a limiting mechanism is provided on the limiting part of the positioning seat 1. The limiting mechanism includes a limiting rod 3 and a limiting block 4. The limiting rod 3 is arranged parallel to the limiting part of the positioning seat 1, and the limiting rod 3 and the positioning seat 1 are movably connected. The limiting block 4 is arranged on the limiting end of the limiting rod 3. The width of the fixing part of the positioning seat 1 is smaller than the width of the positioning seat 1, forming a fixing base surface. Two internal thread type fixing holes 2 are preset at equal intervals on the fixing base surface. Two sets of limiting rods 3 and limiting blocks 4 are correspondingly provided. The limiting rods 3 in the two sets are corresponding to positioning pins and top rods. The limiting blocks 4 in the two sets are corresponding to limiting posts and limiting plates. A handle 5 is provided on the side of the positioning pin and top rod away from the limiting block 4. A clearance hole 6 is preset at the connection between the limiting rod 3 and the limiting part of the positioning seat 1, and a compression spring 7 connected to the limiting rod 3 is preset inside the clearance hole 6.

[0028] In this embodiment:

[0029] First, a specified number of positioning seats 1 are installed on the external welding bracket through the fixing holes 2;

[0030] Secondly, place the lower frame to be welded (such as the panel of a metal tray) and position it so that the outer positioning reference surface of the frame is close to the positioning surface of the positioning seat 1.

[0031] Next, push the handle 5 connected to the two limit rods 3 (positioning shaft and top rod) respectively, so that the two limit blocks 4 (limiting post and limit plate) are fully extended out of the groove on the positioning seat 1. After rotating the handle 5 at an appropriate angle, release the handle 5. At this time, under the action of the compression spring 7 in the clearance hole 6, the limit post and limit plate will be tightly attached to the positioning surface of the positioning seat 1.

[0032] Then, place the second frame (such as the legs of a metal pallet), ensuring that its reference surface is in close contact with the limiting plate in one direction and the positioning shaft in the other direction, thereby determining the position of the upper frame relative to the lower frame. By using several sets of this positioning device in pairs, the relative positions of the upper frame and the lower frame (such as the legs and panel of a metal pallet, as well as the upper frame and the frames—for example, the legs of a metal pallet and the legs of the upper frame) can be determined. After determining the positional relationship between each frame using this positioning device, the welding process is carried out by external manual welding or welding robots.

[0033] Finally, after welding is completed, turn handle 5 to disengage the two limiting blocks 4 (limiting post and limiting plate) from the support of positioning seat 1 and automatically retract them into the groove of positioning seat 1 under the action of compression spring 7, ensuring that the workpiece is not interfered with or stuck when it is taken out and can be easily removed.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
