Description

Technical Field

[0001] The invention relates to the field of automobile mounting structures, in particular to a projection welding standard part mounting tool. Background Art

[0002] During the development of the vehicle body, many installation points are often designed on the body in white for the installation of the interior parts. Most of these installation points are in the form of projection welding bolts or projection welding nuts. Some installation parts have high requirements for the rigidity of the body installation points, such as the seat / CCB installation points have high requirements for the rigidity and strength of the body sheet metal installation points. Therefore, these installation points with high strength and rigidity requirements are often made into box shapes, and then welded bolts or nuts are used to provide installation points for the assembly parts. These box parts are often designed to be relatively small during the design process due to the space of the surrounding parts and the weight and cost of the whole vehicle, resulting in some space problems of projection welding boxes during the welding process of projection welding bolts / nuts.

[0003] Generally speaking, during the design process of these box projection welding parts, the volume of the box is often designed to be relatively small due to some restrictions in order to provide sufficient strength and rigidity for the installation point. However, if the space designed for the box part is relatively small or the structure is relatively complex, then the bolts or nuts of the projection welding points will have problems with the bolt and nut mounting and the operating space of the upper electrode arm during the projection welding process. Generally, due to the size limitation of the box, projection welding parts on box parts will have problems with welding space and standard parts mounting. Usually, the welding space problem will require the projection welding machine to select the smallest size of the projection welding upper electrode for production. If it is difficult to mount standard parts, either the operator is required to overcome the difficulty, which will increase the production time, or the product design engineer is required to modify the data, add welding nut plates or divide the box parts into parts to solve the production problem of difficult welding mounting.

[0004] If you choose to add a nut plate or divide the box into parts, it will increase the welding process, increase welding tools and equipment, and increase production and vehicle costs. Summary of the invention

[0032] The present invention provides a tool for loading standard parts for projection welding, which can solve the problem that a projection welding box with a small space cannot load standard parts. Specifically, the tool for loading standard parts for projection welding of the present invention includes a picking device 10, an adjusting device 20 and a handle device 30. The picking device 10 includes a limiting structure 11 and an adsorption structure 12, and the adsorption structure 12 is provided at the bottom of the limiting structure 11; the adjusting device 20, the adjusting device 20 is connected to the picking device 10; the handle device 30, the handle device 30 is connected to the adjusting device 20; wherein the adjusting device 20 and the handle device 30 cooperate to adjust the size of the tool; the adsorption structure 12 adsorbs and fixes the standard part 40 to load the standard part 40 to a predetermined installation position.

[0033] In order to solve the problem of difficulty in loading standard parts for projection welding due to the size limitation of the box parts, this patent designs a tooling for loading standard parts for projection welding. The tooling can effectively utilize the narrow box space by adjusting the size of the tooling. After picking up the standard parts for projection welding, the standard parts for projection welding can be easily sent to the welding position for welding. The tooling has a simple structure, accurate picking and positioning of standard parts, and can stably send standard parts to the welding position through a narrow space. The tooling cost is low, the space requirement for the box parts is small, and the whole process is simple to operate. It greatly improves the problem of welding operation space, provides a larger design space for product design, and reduces the space and financial costs of product design and design changes.

[0034] like Figure 1 As shown, the small space projection welding standard component loading tool provided by the present invention includes a pick-up device 10, an adjustment device 20 and a handle device 30. The pick-up device 10 is installed at the bottom of the adjustment device 20, and the handle device 30 is connected to the adjustment device 20. The size of the loading tool can be changed by the position of the adjustment device 20. When in use, the user can hold the top of the handle device 30 with his hand, insert the pick-up device 10 into the projection welding box, and adjust the tool size as needed to finally complete the standard component loading.

[0035] like Figure 2 , 3 As shown, the pickup device 10 includes a limiting structure 11, an adsorption structure 12 and an elastic structure 13. The limiting structure 11 includes a cover plate 111 and a side plate 112. The cover plate 111 is a semicircular structure with a certain thickness, and a cover plate through hole 114 is provided on the cover plate 111. The cover plate through hole 114 is a through hole structure. The side plate 112 is a plate-like structure arranged around the cover plate 111. The side plate 112 extends vertically along the edge of the cover plate 111 and is an integrated structure with the cover plate 111. The cover plate 111 and the side plate 112 surround to form a semicircular receiving space 113. The adsorption structure 12 is installed on the bottom side plate of the cover plate 111 of the limiting structure 11. The adsorption through hole is provided on the adsorption structure 12, and the adsorption through hole corresponds to the shape and position of the cover plate through hole 114 on the cover plate 111. The cover plate fixing part 14 passes through the cover plate through hole 114 and the adsorption through hole and is tightened to fix the adsorption structure 12 to the bottom of the cover plate 111. The cover plate fixing part 14 is generally a bolt. The adsorption structure 12 is a strong magnetic structure, and a suitable magnetic material can be selected according to actual needs. There is no restriction on the shape of the adsorption structure 12, and circular, square or irregular shapes are all possible. In the present invention, the elastic structure 13 is a spring structure, and the elastic structure 13 is installed on the inner wall of the side plate 112 of the limiting structure 11, and is arranged in a semicircular shape along the inner wall of the side plate 112. According to different requirements in the embodiment, the material of the elastic structure 13 includes but is not limited to rubber material and spring material, as long as it is ensured that the elastic structure 13 can absorb dynamic potential energy and convert it into elastic potential energy, and the hollow space formed by the elastic structure 13 is smaller than the top size of the standard part 40. Specifically, in some embodiments, the elastic structure 13 is a retractable spring, and the elastic structure 13 can be fixed to the side plate 112 by bonding.

[0036] Furthermore, when the standard part 40 needs to be installed on the pickup device 10, the standard part 40 is adsorbed to the bottom of the limiting structure 11 through the adsorption structure 12, and the standard part 40 is located in the receiving space 113 in the pickup device 10. Since the top area of ​​the standard part 40 is larger than the area of ​​the hollow part formed by the elastic structure 13, the elastic structure 13 is deformed, and the elastic structure 13 and the standard part 40 are interference-fitted, fixing the standard part 40 at the center of the limiting structure 11. When the pickup device 10 enters the projection welding box to install the standard part 40, it is only necessary to align the standard part with the installation hole and insert it, and then move the pickup device 10 parallel to separate the adsorption structure 12 from the standard part 40, and the standard part tooling can be completed.

[0037] like Figure 1-5As shown, the adjusting device 20 is a rod-shaped structure, on which a through slot 21 is provided. The through slot 21 is a long strip-shaped slot body that can accommodate bolts to pass through. During the development of the vehicle body, many mounting points are often designed on the white body due to the installation of the final assembly interior parts. Most of these mounting points are embodied in the form of projection welding bolts or projection welding nuts. In addition, since some mounting parts have higher requirements on the rigidity of the vehicle body mounting points, such as the seat / CCB mounting points have higher requirements on the rigidity and strength of the vehicle body sheet metal mounting points, these mounting points with higher strength and rigidity requirements are often made into a box shape, and then welded bolts or nuts are used to provide mounting points for the final assembly parts. These box parts are often designed to be relatively small during the design process due to the space of the surrounding parts and the weight and cost of the whole vehicle, resulting in some projection welding box space problems during the welding process of the projection welding bolts / nuts. In the face of the narrow projection welding box space, the present invention selects to use the adjusting device 20 and the handle device 30 with a smaller volume as the control structure to send the standard parts to the position where the standard parts need to be installed. The adjusting device 20 is fixedly connected to the picking device 10, and the bottom end of the adjusting device 20 is welded to the outer wall of the side plate 112 of the picking device 10. The handle device 30 includes a fixing structure 33, a connecting structure 34 and a gripping structure 35, wherein a plurality of handle through holes 31 are provided on the fixing structure 33, and the handle through holes 31 correspond to the positions of the through slots 21 on the adjusting device 20. The handle fixing member 32 passes through the specific handle through holes 31 and the through slots 21 to fix the adjusting device 20 on the fixing structure 33 of the handle device 30, and the handle fixing member 32 is generally a bolt. At the same time, the position of the adjusting device 20 can be adjusted by changing the handle through holes 31 passed through, so as to achieve the effect of adjusting the overall size of the upper tooling. In one embodiment of the present invention, three handle through holes 31 are provided, and different through holes can be selected to pass through to achieve different size positioning effects. The fixing structure 33 and the gripping structure 35 are fixedly connected by the connecting structure 34. The connecting structure 34 is a curved structure. The fixing structure 33 and the gripping structure 35 are respectively fixed at both ends of the connecting structure 34. Therefore, there is a certain angle between the fixing structure 33 and the gripping structure 35. This design is to cope with the complex space conditions of the projection welding box. The connecting structure 34 can be artificially formulated during manufacturing, and the degree of curvature of the connecting structure 34 can be adjusted according to actual needs to adapt to the installation environment under different conditions.

[0038] The present invention proposes a projection welding standard part loading tooling, which fixes the standard part at the bottom of the limit component by designing an adsorption component, and then extends the limit component into the projection welding through the handle component to install the standard part, thereby completing the installation of the standard part in a small space.

[0039] Furthermore, the present invention provides a projection welding standard parts loading tool, which takes advantage of the small space occupation rate of the adjustment device and the handle device, and can load the parts in a small space projection welding box in a complex environment.

[0040] Therefore, the problem that standard parts cannot be installed in a projection welding box with a small space can be solved by using a projection welding standard part loading tool of the present invention.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
