Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and in particular relates to a welding fixture for a straw bag support. Background Technology

[0002] Grass clipping bags are primarily used to collect grass clippings after lawn mowing. They can also be used for flood control, dike construction, slip prevention, and landscaping. The grass clipping bag support frame is one of the important supporting components, consisting of an upper frame and a lower frame. (See attached image) Figure 1 As shown, the existing grass collection bag support includes a support connecting plate 100, a U-shaped rod 200, a pressure plate 300, and mounting lugs 400. The support connecting plate 100 and the mounting lugs 400 are each configured in twos and are welded and fixed to the U-shaped rod 200 together with the pressure plate 300. Nuts 500 are welded to the outer side of each of the two mounting lugs 400 for installation and connection.

[0003] Existing welding methods cannot pre-assemble the components of the lower support; instead, each component must be welded onto the U-shaped rod one by one. Furthermore, the welding points of each component need to be marked in advance during the welding process, which is cumbersome and results in low welding efficiency. In addition, manual marking leads to poor positioning accuracy, affecting the overall welding quality. Therefore, we propose a straw bag lower support welding fixture to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figures 2-7 As shown, this embodiment provides a welding fixture for a straw bag support, including a base plate 1, a first positioning block 2, a second positioning block 3, a third positioning block 4, and a fourth positioning block 5. At least one weight-reducing hole 12 is provided on the top of the base plate 1. By providing the weight-reducing hole 12, the weight of the entire base plate 1 can be reduced, making the fixture easier to use and allowing for the recycling and reuse of the reduced material.

[0030] Multiple first positioning blocks 2 are provided and are evenly distributed on the two short sides and one long side edge of the top of the base plate 1. The top of each of the multiple first positioning blocks 2 is provided with a positioning groove 21 for positioning and locking the U-shaped rod 200.

[0031] Two second positioning blocks 3 are provided, symmetrically located at the two corners of one of the long sides of the top of the base plate 1, for overlapping the two ends of the U-shaped rod 200. Two first positioning holes 31 are symmetrically opened on one side of the second positioning block 3, and a first positioning rod 6 is inserted into each of the two first positioning holes 31. After the U-shaped rod 200 on the lower bracket is limited and overlapped through the positioning grooves 21 on the multiple first positioning blocks 2, the two ends of the U-shaped rod 200 overlap the tops of the two second positioning blocks 3 respectively, and are close to the edges of the second positioning blocks 3. Then, from the side of the two second positioning blocks 3 that are far apart from each other, the first positioning rods 6 are inserted into the two first positioning holes 31, and the insertion ends of the two first positioning rods 6 extend outward to the other side of the second positioning blocks 3. At this time, the connecting plate 100 can be fitted onto the extended ends of the two first positioning rods 6 through the two through holes designed on it, thereby positioning the connecting plate 100 and pushing the connecting plate 100 to contact one side of the second positioning block 3, thereby making it contact one end of the U-shaped rod 200, thus completing the docking of the connecting plate 100 and the end of the U-shaped rod 200.

[0032] Two third positioning blocks 4 are also provided, symmetrically located at the two short edges of the top of the base plate 1. A second positioning hole 41 is provided on one side of each third positioning block 4, and a second positioning rod 7 is inserted into the second positioning hole 41. Before positioning and locking the U-shaped rod 200, the two second positioning rods 7 need to be inserted through the second positioning holes 41 from the opposite sides of the two third positioning blocks 4. After being inserted into the second positioning holes 41, the inserted end of the second positioning rod 7 will extend outwards by a certain length. Then, the mounting lug 400 can be positioned by fitting it onto the extended section through its designed through hole. Since the mounting lug 400 is L-shaped, after being fitted onto the second positioning rod 7, one side of the mounting lug 400 contacts one side of the third positioning block 4, and the other side contacts the top of the third positioning block 4. Then, the U-shaped rod 200 is locked in place, overlapping and pressing against the mounting lug 400, thus completing the positioning. Finally, the nut is also placed on the extension of the second positioning rod 7 for positioning, and it is made to abut against the mounting lug 400. The top edges of the two third positioning blocks 4, which are close to each other, are provided with a first arc-shaped chamfer 42. The first arc-shaped chamfer 42 allows for the overlap of the bent portion of the mounting lug 400, thereby improving the docking accuracy with the U-shaped rod 200.

[0033] A fourth positioning block 5 is provided, located at one of the short edges of the top of the base plate 1, between the adjacent first positioning block 2 and third positioning block 4, for supporting and positioning the overlap between the pressure plate 300 and the U-shaped rod 200. The top outer edge of the fourth positioning block 5 is provided with a second arc-shaped chamfer 51. The second arc-shaped chamfer 51 accommodates the overlap of the bent portion of the pressure plate 300, thereby improving the docking accuracy between the pressure plate 300 and the U-shaped rod 200.

[0034] The bottoms of multiple positioning blocks 2, two second positioning blocks 3, two third positioning blocks 4, and the fourth positioning block 5 are all provided with snap-fit ​​parts, and the top of the base plate 1 is provided with multiple snap-fit ​​holes 11 for corresponding positioning snap-fit. The positioning blocks 2, second positioning blocks 3, third positioning blocks 4, and fourth positioning blocks 5 are all designed to be detachable, which facilitates the assembly, use, or replacement of each component and effectively avoids the overall scrapping.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
