[0027] according to Figure 1 As shown, the tripod of the edge-pulling machine's engagement component is assembled and welded from multiple welded parts. This embodiment is based on... Figure 1 The welding parts of the edge-pulling machine's engagement component tripod are numbered. The edge-pulling machine's engagement component tripod includes welding part 1, welding part 2, welding part 3, welding part 4, welding part 5, and welding part 6. According to... Figure 1It can be seen that the tripod of the edge-pulling machine's biting component has a symmetrical structure. The second weldment 2 and the fourth weldment 4 have the same shape and size. There are three sixth weldments 6, which are welded inside the tripod of the edge-pulling machine's biting component to form three 90° right-angle connections, serving as stiffeners for fixation. Two sixth weldments 6 are set in the horizontal direction, which are respectively fixed at the right-angle connection between the first weldment 1 and the second weldment 2, and at the right-angle connection between the first weldment 1 and the fourth weldment 4. One sixth weldment 6 is set in the vertical direction, which is fixed at the right-angle connection between the first weldment 1 and the third weldment 3.

[0028] according to Figures 2-5 As shown, this embodiment provides a welding and positioning device for a tripod of a sewing machine biting component, including a first welding fixture and a second welding fixture. The first welding fixture and the second welding fixture are set according to the spatial layout and size of the welded parts of the tripod of the sewing machine biting component. The second welding fixture is placed inside the first welding fixture and can support and position the welded parts to be welded by the tripod of the sewing machine biting component.

[0029] The first welding fixture includes a base 10, which is provided with a fixed bracket and a positioning block 11. The positioning block 11 is used to position the first weldment 1 and the second weldment 2. In this embodiment, four fixed brackets are provided, which are distributed in a U-shape on the base 10. The fixed brackets are provided with a clamping mechanism.

[0030] The fixed bracket is divided into a first fixed bracket 21, a second fixed bracket 22, a third fixed bracket 23, and a fourth fixed bracket 24. The third fixed bracket 23 and the fourth fixed bracket 24 are fixed on the same side of the base 10. The second fixed bracket 22 and the third fixed bracket 23 are respectively fixed on opposite sides of the base 10. The first fixed bracket 21 is perpendicular to the second fixed bracket 22. The first fixed bracket 21 is fixed above the second fixed bracket 22. The inner sides of the first fixed bracket 21 and the second fixed bracket 22 are perpendicular to each other and to the base 10, thereby ensuring the formation of a three-dimensional welding reference positioning surface.

[0031] The clamping mechanism includes a spiral assembly 31 and a spring assembly 32. The third fixed bracket 23 and the fourth fixed bracket 24 are provided with spiral assemblies 31, and the first fixed bracket 21 and the second fixed bracket 22 are provided with spring assemblies 32.

[0032] The spiral assembly 31 includes a pressure plate 311, which is connected to a bolt 313 via a cotter pin 312. The pressure plate 311 is circular, and the cotter pin 312 is fixed at the center of the pressure plate 311. The bolt 313 passes through a third fixed bracket 23 or a fourth fixed bracket 24 and is connected to the cotter pin 312. The bolt 313 has a cylindrical pin 314 at its end. By rotating the cylindrical pin 314, the distance the bolt 313 passes through the third fixed bracket 23 or the fourth fixed bracket 24 is controlled to fix the fourth weldment 4, thus realizing the formation of the basic frame of the tripod of the edge-pulling machine's biting component.

[0033] The clamping plate 311 and the bolt 313 are connected by a circular pin hole. The clamping surface of the clamping plate 311 is circular, which increases the contact area. The connection can completely eliminate the phenomenon that the force is not perpendicular to the clamping surface.

[0034] The first fixed bracket 21 is provided with a spring assembly 32, which includes a pressure plate 321. The pressure plate 321 is connected to a nut 322. The cylindrical threaded surface of the nut 322 passes through the first fixed bracket 21 and is connected to the pressure plate 321. The pressure plate 321 is inside the first fixed bracket 21, and a spring 323 is sleeved on the outside of the nut 322. The pressure plate 321 is L-shaped, and the elastic force of the spring 323 is adjusted by the screwing position of the nut 322. By pulling and rotating the pressure plate 321, the first weldment 1 can be quickly positioned and locked.

[0035] The second fixed bracket 22 is provided with a spring assembly 32. The nut 322 is fixed to the top of the second fixed bracket 22 and fixed to the second fixed bracket 22 by a fixing plate (not shown in the figure). The nut 322 passes through the fixing plate. The pressure plate 321 is provided on the inner side of the second fixed bracket 22 for fixing the second weldment 2.

[0036] The second welding fixture includes a base plate 40, which is provided with a plurality of rectangular tube support columns. The rectangular tube support columns are divided into first rectangular tube support columns 41 and second rectangular tube support columns 45. In this embodiment, four first rectangular tube support columns 41 are provided. The four first rectangular tube support columns 41 are of the same height and are provided with threaded universal ball joints 43 on their tops. The first rectangular tube support columns 41 are arranged on the four sides of the base plate 40. A horizontal plate 44 is provided between the first rectangular tube support columns 41 for fixation. There are three horizontal plates 44, one of which is provided with a handle 42 to facilitate the placement of the second welding fixture inside the first welding fixture.

[0037] The bottom of the base plate 40 is provided with a threaded universal ball joint 43, and the bottom of the second welding fixture is in point contact with the first welding fixture, which enables the second welding fixture to move easily inside the first welding fixture. In this embodiment, by providing a threaded universal ball joint 43 at the bottom of the base plate 40 and a threaded universal ball joint 43 on the second rectangular tube support column 45, the height of the second welding fixture can be adjusted, thereby ensuring the shape and position dimensions of the fifth weldment 5.

[0038] In this embodiment, two second rectangular tube support columns 45 are provided. The second rectangular tube support columns 45 are located on one side of the base plate 40. There is no horizontal plate 44 between them and the first rectangular tube support columns 41. The height of the two second rectangular tube support columns 45 is lower than that of the four first rectangular tube support columns 41. A clamping component is provided on the top of the second rectangular tube support columns 45.

[0039] The clamping assembly includes a clamping plate 52, which is fixed to the top of the spacer 51 by bolts. The top of the clamping plate 52 is provided with a clamping bolt 53. By fixing the sixth weldment 6 in the horizontal direction to the top of the second rectangular tube support column 45, the sixth weldment 6 in the horizontal direction is clamped in the gap between the second rectangular tube support column 45 and the clamping plate 52, and then the clamping bolt 53 is used to clamp the sixth weldment 6. At this time, welding will not produce deviation.

[0040] A groove (not shown in the figure) is provided on one side of the bottom. A sliding cylinder 61 is provided inside the groove. A telescopic spring 62 is sleeved on the sliding cylinder 61. The sixth weldment 6 in the vertical direction is fixed between the end face of the sliding cylinder 61 and the end face of the groove of the bottom plate 40 by the elastic force of the telescopic spring 62, so as to realize the welding positioning of the sixth weldment 6.

[0041] The working principle of the tripod welding and positioning device for the edge-pulling machine's biting component in this embodiment is as follows:

[0042] like Figure 4 As shown, the first weldment 1 is placed inside the first welding fixture and upright on the inner side of the first fixed bracket 21, so that the first weldment 1 is completely in contact with the positioning block 11. Then, the pressure plate 321 is pulled outward by rotating it, and the force of the spring 323 is used to lock and fix the first weldment 1. The second weldment 2 is placed upright on the inner side of the second fixed bracket 22, so that the second weldment 2 is completely in contact with the first weldment 1. Then, the pressure plate 321 is pulled outward by rotating it, and the force of the spring 323 is used to lock and fix the second weldment 2. The third weldment 3 is placed on the plane of the base 10, so that the third weldment 3 is completely in contact with the first weldment 1 and the second weldment 2. After completing the above steps, the inner mating paths of the first weldment 1, the second weldment 2, and the third weldment 3 are segmented spot welded.

[0043] like Figure 5As shown, based on the welding height of the fifth weldment 5 of the tripod of the edge-pulling machine's biting component and the sixth weldment 6 in the horizontal direction, the height of the second welding fixture is adjusted. First, by adjusting the threaded rod universal ball 43 at the bottom of the base plate 40, the plane height dimension of the second rectangular tube support column 45 is made consistent with the welding height dimension of the sixth weldment 6 in the horizontal direction. Then, the threaded rod universal ball 43 is locked, and the sixth weldment 6 in the horizontal direction is fixed in the gap between the second rectangular tube support column 45 and the clamping plate 52 by rotating the clamping bolt 53 at the top of the clamping plate 52, thereby achieving the locking and fixing of the sixth weldment 6 in the horizontal direction.

[0044] Then, adjust the height of the threaded rod universal ball 43 at the top of the first rectangular tube support column 41 to match the welding height of the fifth weldment 5. Then, lock the threaded rod universal ball 43 and place the second welding fixture, which has been adjusted in height, on the upper surface of the third weldment 3, so that the base plate 40 of the second welding fixture is completely in contact with the first weldment 1 and the second weldment 2 of the tripod of the edge-pulling machine biting component. Place the fifth weldment 5 on the plane of the threaded rod universal ball 43 at the top of the first rectangular tube support column 41. Then, place the fourth weldment 4 upright inside the third fixed bracket 23 and the fourth fixed bracket 24. Press and fix the fourth weldment 4 with the spiral assembly 31 and the fifth weldment 5. According to the welding space requirements of the tripod of the edge-pulling machine biting component, the fifth weldment 5 is not in contact with the first weldment 1 at this time, and maintains a certain space distance from the first weldment 1, which plays a role in giving way and supporting positioning.

[0045] The sixth weldment 6 in the horizontal direction is fixed to the top of the second rectangular tube support column 45 and is pressed in the gap between the second rectangular tube support column 45 and the clamping plate 52 by adjusting the clamping bolt 53. Then, the sixth weldment 6 in the vertical direction is fixed between the end face of the sliding cylinder 61 and the end face of the groove of the base plate 40 by the elastic force of the telescopic spring 62. Then, the sixth weldment 6 is spot welded in sections at the joint path with other weldments.

[0046] After completion, slightly loosen the spiral assembly 31 of the third fixed bracket 23 and the fourth fixed bracket 24 of the first welding fixture, and move the fifth welded part 5 of the edge-pulling machine biting component tripod forward so that the fifth welded part 5 is completely in contact with the second welded part 2, the first welded part 1, and the fourth welded part 4. Then, lock and fix the fourth welded part 4 again through the spiral assembly 31 of the third fixed bracket 23 and the fourth fixed bracket 24 of the first welding fixture. Finally, perform intermittent spot welding to fix the fifth welded part 5 of the edge-pulling machine biting component tripod at the docking path with other welded parts. Finally, pull out the second welding fixture through the handle 42 and loosen the clamping assembly 31 of the first welding fixture to finally obtain the edge-pulling machine biting component tripod.

[0047] This invention, through the setting of a simple first and second welding fixture, enables rapid welding of the tripod of the edge-pulling machine's engagement component, allowing the operator to independently complete the assembly welding. Using the welding positioning device of this invention to complete the assembly welding optimizes the production process, eliminating the original marking and correction steps, thus saving production time and labor costs. For batch welding of the tripod of the edge-pulling machine's engagement component, centralized assembly spot welding is adopted, doubling production efficiency. Furthermore, the welding positioning device of this invention employs standard welding methods and techniques, achieving uniformity and stability of product characteristics.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
