[0029] Reference below Figures 1 to 5 The welding jig according to the embodiment of the present invention is described.

[0030] like Figures 1 to 3 、 Figure 5 As shown, the welding jig according to the embodiment of the present invention includes: a positioning table 100, a cover assembly 200 and a first pushing assembly 300, the positioning table 100 is provided with a first workstation for positioning the first workpiece to be welded 500 in the horizontal direction, and the first workstation is provided with a first magnet 110; the cover assembly 200 is rotatably connected to the positioning table 100 and includes a connected cover 210 and a second magnet 220, and the second magnet 220 and the first magnet 110 have a mutual magnetic attraction effect so that the cover 210 can press the first workpiece to be welded 500; the first pushing assembly 300 includes a first pushing member 310, a first elastic member 320 and a first driving member 330, the first pushing member 310 is provided with a second workstation for carrying and positioning the second workpiece to be welded 600, the output end of the first driving member 330 is connected to the first pushing member 310 through the first elastic member 320, and is used to drive the first pushing member 310 close to or away from one side of the first workstation, so that the second workpiece to be welded 600 is flexibly abutted against the side wall of the first workpiece to be welded 500.

[0031] It can be understood that this welding fixture includes a positioning table 100, a cover assembly 200 and a first pushing assembly 300. When in use, the first workpiece 500 to be welded is placed and positioned on the first station on the positioning table 100, and the second workpiece 600 to be welded is placed and positioned on the second station of the first pushing member 310. The second magnet 220 connected to the cover 210 and the first magnet 110 on the first station are magnetically attracted to each other, so that the cover 210 can press the first workpiece 500 to be welded. Then, the first pushing member 310 is pressed against the first driving member 330. When driven, the side wall of the second part to be welded 600 can be brought into contact with the side wall of the first part to be welded 500. Since a first elastic member 320 is provided between the first pushing member 310 and the first driving member 330, the first part to be welded 500 and the second part to be welded 600 are flexibly abutted, which reduces the damage between the workpieces to be welded, thereby facilitating the welding of the side wall of the first part to be welded 500 and the side wall of the second part to be welded 600; therefore, the welding jig of the present application can realize the positioning of the two parts to be welded and improve the welding accuracy of the side walls of the two parts to be welded.

[0032] It is understandable that the first pushing assembly 300 further includes a first connecting shaft and a first limiting member 340, one end of the first connecting shaft is connected to the output end of the first driving member 330, the other end of the first connecting shaft is inserted into the first pushing member 310, the first limiting member 340 is fixedly sleeved on the first connecting shaft, and the first elastic member 320 is connected between the first limiting member 340 and the first pushing member 310. For example, Figure 3 As shown, in this embodiment, the first pushing member 310 is movably sleeved on one end of the first connecting shaft, and the other end of the first connecting shaft is connected to the output end of the first driving member 330. A first limiting member 340 is fixed on the first connecting shaft, and the first limiting member 340 is located between the first pushing member 310 and the first driving member 330. The first elastic member 320 is located between the first pushing member 310 and the first limiting member 340, so that after the first pushing member 310 is driven by the first driving member 330 to approach the first workstation, the second part to be welded 600 on the first pushing member 310 abuts against the first part to be welded 500. However, due to the presence of the first elastic member 320, even if the first connecting shaft and the first limiting member 340 continue to approach the first workstation under the drive of the first driving member 330, the second part to be welded 600 no longer moves after abutting against the first part to be welded 500, and squeezes the first elastic member 320 to deform, thereby achieving the second part to be welded 600 and the first part to be welded 500 to be tightly abutted, and avoiding collision damage.

[0033] It is understandable that the positioning platform 100 is provided with a first limiting portion 120, which is located on one side of the first station. When the first pusher 310 abuts against the first limiting portion 120, the second workpiece 600 to be welded flexibly abuts against the side wall of the first workpiece 500 to be welded. Figures 2 to 3 As shown, in this embodiment, a first limiting portion 120 is provided on one side of the first workstation. The first limiting portion 120 is used to limit the first pushing member 310 from continuing to approach the first workstation after the second part to be welded 600 flexibly abuts against the side wall of the first part to be welded 500, thereby playing a good limiting role.

[0034] It is understood that at least one second pushing assembly 400 is also included, the first pushing member 310 is provided with a receiving groove 311 for receiving the lower portion of the second part to be welded 600, and the second pushing assembly 400 is used to flexibly press the second part to be welded 600 and the upper portion of the side wall of the first part to be welded 500. For example, Figure 4 As shown, in this embodiment, since the lower part of the second part to be welded 600 is accommodated and positioned in the accommodating groove 311 of the first pushing member 310, when the first pushing member 310 drives the second part to be welded 600 to abut against the side wall of the first part to be welded 500, the upper part of the second part to be welded 600 is prone to shaking. Therefore, the second pushing assembly 400 can press the upper part of the side wall of the second part to be welded 600 and the first part to be welded 500, thereby improving the stability during the welding process and further improving the welding accuracy.

[0035] It can be understood that the second pushing assembly 400 includes a second driving member 410, a second elastic member 420, a second pushing member 430 and an abutting member 440. The second pushing member 430 and the abutting member 440 are fixed. The second elastic member 420 is connected between the second driving member 410 and the second pushing member 430. The positioning platform 100 is provided with a second limiting portion 130. When the abutting member 440 abuts against the second limiting portion 130, the second pushing member 430 flexibly abuts against the upper portion of the side wall of the second workpiece to be welded 600. For example, Figure 4 As shown, in this embodiment, when the abutment member 440 abuts against the second limiting portion 130 on the positioning platform 100 under the drive of the second driving member 410, the second pushing member 430 presses the upper part of the side wall of the second part to be welded 600, thereby achieving the pressing of the second part to be welded 600 and the upper part of the side wall of the first part to be welded 500.

[0036] It is understood that the cover assembly 200 further includes a handle 240, which is connected to the cover 210 and is used to lift the cover 210. Figure 5 As shown, in this embodiment, the cover plate 210 is conveniently pressed or opened on the first workpiece to be welded 500 by swinging the handle 240 .

[0037] It is understandable that the second magnet 220 is embedded on the side of the cover 210 away from the handle 240. Figure 5 As shown, in this embodiment, the second magnet 220 is embedded on a side of the cover 210 away from the handle 240 to improve the effect of the user's force application.

[0038] It is understood that the first station is provided with a first positioning member for positioning the first workpiece to be welded 500, and the second station is provided with a second positioning member 312 for positioning the second workpiece to be welded 600 in the horizontal direction. Figures 2 to 3 As shown, in this embodiment, the first part to be welded 500 can be placed on the first positioning member when placed on the first work station, thereby realizing the horizontal positioning of the first part to be welded 500, and the second part to be welded 600 can be placed on the second positioning member 312 when placed on the second work station, thereby realizing the horizontal positioning of the second part to be welded 600.

[0039] It is understood that the positioning platform 100 is provided with a first guide groove 140 and a second guide groove 150, the first pusher 310 is slidably connected to the first guide groove 140, and the second pusher 430 is slidably connected to the second guide groove 150. For example, Figure 2 As shown, in this embodiment, the first pushing member 310 can slide along the first guide groove 140 on the positioning table 100 under the drive of the first driving member 330, and the second pushing member 430 can slide along the second guide groove 150 on the positioning table 100 under the drive of the second driving member 410, thereby improving the linearity of the sliding, and further improving the alignment degree of the two workpieces to be welded and the final welding yield.

[0040] It is understandable that the second pusher 430 is provided with an avoidance position 431 for avoiding the second workpiece to be welded 600. Figure 4 As shown, in this embodiment, an avoidance position 431 is provided at the lower portion of the second pushing member 430 , thereby avoiding interference between the second pushing member 430 and the second workpiece to be welded 600 .

[0041] It should be understood that in this embodiment, two groups of second pushing components 400 are provided, and are respectively located on both sides of the first pushing component 300 to achieve compression of both sides of the upper side wall of the second part to be welded 600 and achieve welding at the two compression positions.

However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
