[0002] In the production of automotive parts, welding of studs to automotive parts is often involved. Current technology typically involves placing the automotive part and stud on the lower electrode, then pressing down with a welding torch equipped with the upper electrode to complete the welding.
[0003] However, the structure of car parts is not regular, and the center of gravity is unstable when placed on the lower electrode; the worker needs to hold the car part with one hand and press it with the welding gun with the other hand to complete the welding; welding in this way is very inconvenient. Summary of the Invention
[0004] The purpose of this utility model is to provide a stud welding device that makes welding operations more convenient for workers.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A stud welding device includes: an upper electrode extending in a vertical direction, a first bracket for mounting the upper electrode, a power source for driving the first bracket to move vertically, a lower electrode extending in a vertical direction, and a second bracket for mounting the lower electrode; wherein, the first bracket is adapted to form a first locking member to lock the upper electrode, and the first bracket and the first locking member are detachably connected; the second bracket is adapted to form a second locking member to lock the lower electrode, and the second bracket and the second locking member are detachably connected; the top of the lower electrode is provided with a downwardly extending third positioning hole to accommodate the shank of the stud.
[0007] Optionally, it also includes: a support mechanism; the support mechanism includes: a support member extending in the vertical direction, and a third bracket for installing the support member; the support member is provided in multiple ways; the third bracket is provided with multiple first through holes extending vertically for installing the support member; the support member is screw-shaped and adapted to be installed in the first nut of the first through hole.
[0008] Optionally, a limiting member is installed on the top of the support member; the limiting member includes: a connecting part extending in a horizontal direction, and a limiting part extending upward from one end of the connecting part; the connecting part has a second through hole extending vertically through at one end away from the limiting part, so that the support member can pass through; the support member is provided with a second nut for fixing the connecting part.
[0009] Optionally, the power source is configured as a linear cylinder.
[0010] Optionally, it may also include: a controller; the power source is controlled by the controller.
[0011] Optionally, the first bracket is provided with a first positioning groove that runs vertically through the side, and the first locking member is provided with a first limiting groove corresponding to the first positioning groove, so as to clamp the upper electrode; the first bracket and the first locking member are connected by bolts.
[0012] Optionally, the second bracket is provided with a second positioning groove that runs vertically through the side, and the second locking member is provided with a second limiting groove corresponding to the second positioning groove, so as to clamp the lower electrode; the second bracket and the second locking member are connected by bolts.
[0013] Optionally, the first bracket has a first positioning hole that extends vertically through it, and a first threaded hole that extends horizontally from the first positioning hole to the outer wall; the upper electrode is installed in the first positioning hole; the first locking member is configured as a bolt and is installed in the first threaded hole.

[0015] The working principle of this invention is as follows: Most automotive parts have holes for mating with studs. The shank of the stud passes through the hole in the automotive part, with the cap supporting it. The automotive part is placed on the lower electrode, and the shank of the stud is accommodated in the third positioning hole at the top of the lower electrode. Holding the automotive part by hand and starting the power source, the power source drives the first bracket to move the upper electrode downwards, thus welding the stud and the automotive part. A small number of automotive parts do not have holes for mating with studs. In this case, the stud is first placed in the third positioning hole at the top of the lower electrode, and then the automotive part is placed on top of the stud. Holding the automotive part by hand and starting the power source, the power source drives the first bracket to move the upper electrode downwards, thus welding the stud and the automotive part. For automotive parts of different thicknesses, the position of the upper electrode can be adjusted by removing and installing the first locking component, or the position of the lower electrode can be adjusted by removing and installing the second locking component, thereby allowing for better mating between the upper and lower electrodes.
[0016] Therefore, the beneficial effects of this utility model are as follows: The welding of studs to automotive parts can be completed simply by pressing the power source switch with one hand; compared to the worker holding the welding rod and pressing it down with one hand to complete the welding, the operation is much simpler and more convenient. Furthermore, the distance between the upper and lower electrodes can be flexibly adjusted to adapt to the welding of automotive parts and studs of different thicknesses; thus, a fast-responding and low-cost cylinder can be used as the power source; instead of selecting a more expensive linear motor to achieve precise stroke control to adapt to the welding of automotive parts and studs of different thicknesses.

[0029] The following is combined with Figure 1 ~Attached Figure 5 The embodiments of this utility model will be described in detail below.
[0030] This utility model provides a stud welding device. The stud welding device includes: an upper electrode 1 extending vertically, a first bracket 2 for mounting the upper electrode 1, a power source 3 for driving the first bracket 2 to move vertically, a lower electrode 4 extending vertically, and a second bracket 5 for mounting the lower electrode 4. The first bracket 2 is adapted to form a first locking member 6 to lock the upper electrode 1, and the first bracket 2 and the first locking member 6 are detachably connected. It should be understood that by loosening the first locking member 6, the position of the upper electrode 1 can be adjusted, and then it can be re-locked. The second bracket 5 is adapted to form a second locking member 7 to lock the lower electrode 4, and the second bracket 5 and the second locking member 7 are detachably connected. It should be understood that by loosening the second locking member 7, the position of the lower electrode 4 can be adjusted, and then it can be re-locked. The top of the lower electrode 4 has a downwardly extending third positioning hole 8 to accommodate the shank of the stud.
[0031] The specific implementation method of this utility model is described below: Most automotive parts have holes for mating with studs; in this case, the shank of the stud can be passed through the hole in the automotive part, and the cap of the stud can be supported on the automotive part; the automotive part is placed on the lower electrode 4, and the shank of the stud is accommodated in the third positioning hole 8 at the top of the lower electrode 4; the automotive part is held by hand, and the power source 3 is started, so that the power source 3 drives the first bracket 2 to move the upper electrode 1 downward, thereby welding the stud and the automotive part. A small number of automotive parts do not have holes for mating with studs; in this case, the stud can be placed first in the third positioning hole 8 at the top of the lower electrode 4, and then the automotive part is placed on top of the stud; the automotive part is held by hand, and the power source 3 is started, so that the power source 3 drives the first bracket 2 to move the upper electrode 1 downward, thereby welding the stud and the automotive part. For automotive parts of varying thicknesses, the position of the upper electrode 1 can be adjusted by disassembling and assembling the first locking component 6, or the position of the lower electrode 4 can be adjusted by disassembling and assembling the second locking component 7, thereby allowing the upper electrode 1 and the lower electrode 4 to better cooperate. This invention allows the operator to complete the welding of studs to automotive parts simply by pressing the switch of the power source 3 with one hand; compared to the operator holding the welding rod and pressing it down with one hand, the operation is much simpler and more convenient. Furthermore, the distance between the upper electrode 1 and the lower electrode 4 can be flexibly adjusted to accommodate the welding of automotive parts and studs of varying thicknesses. Thus, a fast-responding and low-cost cylinder can be used as the power source 3, eliminating the need for a more expensive linear motor to achieve precise stroke control for welding automotive parts and studs of different thicknesses.

It should be understood that the top of the support member 9 can provide support for the bottom of the automotive part. For automotive parts with irregular bottoms, the height of each support member 9 can be adaptively adjusted in the vertical direction to adapt to the bottom height of different positions of the automotive part. By setting up a support mechanism, not only can the workers' hands be freed; but it can also cooperate with upstream and downstream gripping devices, which is conducive to realizing automated welding. In addition, depending on the actual needs, a rubber sleeve or a plastic cap can be placed on the top of the support member 9.
[0033] Furthermore, a limiting member 12 is installed on the top of the support member 9; the limiting member 12 includes: a connecting portion 13 extending horizontally, and a limiting portion 14 extending upward from one end of the connecting portion 13; the connecting portion 13 has a second through hole extending vertically at the end away from the limiting portion 14, for the support member 9 to pass through; the support member 9 is provided with a second nut for fixing the connecting portion 13. It should be understood that the support member 9 located in the edge area of the automotive part can have the limiting member 12 installed on its top; by rotating the limiting member 12 relative to the support member 9, the limiting portion 14 of the limiting member 12 is brought close to the edge of the automotive part; then the second nut is tightened to keep the limiting member 12 fixed; thus, when placing the automotive part later, the positioning of the automotive part can be determined by the limiting member 12. In addition, the height of the limiting member 12 can be adjusted according to actual needs. The limiting member 12 can be made of plastic.
[0034] Furthermore, the power source 3 is configured as a linear cylinder. It should be understood that the linear cylinder is the optimal choice based on cost and response speed; of course, depending on the actual needs, it can also be replaced with other types of power sources 3, such as linear cylinders.
[0035] Furthermore, it also includes a controller; the power source 3 is controlled by the controller. It should be understood that each time the operator presses the operation button, the power source 3 automatically drives the first support 2 downwards to complete a pressing action, and then returns it to its original position.
