[0032] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0033] First, the welding auxiliary device according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0034] refer to Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of a welding auxiliary device according to an embodiment of the present invention is shown. Figure 2 The structure diagram of the mounting base 310 and the fixing mechanism 100 according to an embodiment of the present invention is shown in FIG. Figure 1 The welding auxiliary device is used in automatic welding lines. Figure 1 and Figure 2 As shown, the welding auxiliary device includes a frame 200 and a gripping mechanism 300. The frame 200 is used to accommodate a component 400 to be welded. The gripping mechanism 300 is arranged on the frame 200, and the gripping mechanism 300 includes a mounting seat 310 and a fixing mechanism 100. The mounting seat 310 is provided with a mounting hole, and the fixing mechanism 100 is connected to the mounting seat 310 through the mounting hole.

[0035] The fixing mechanism 100 includes a fixing member 110 and an ejection member 120. The first end of the fixing member 110 is connected to the top surface of the mounting seat 310, and the second end of the fixing member 110 passes through the mounting hole for detachable connection with the component 400 to be welded. The fixing member 110 is provided with a receiving cavity 111 that at least passes through the second end of the fixing member 110. The ejection member 120 is located in the receiving cavity 111, and one end of the ejection member 120 extends outside the fixing member 110 for detachable connection with the component 400 to be welded. The ejection member 120 can slide relative to the fixing member 110, and extend out of the receiving cavity 111 or retract into the receiving cavity 111.

[0036] Further, the fixing member 110 is a hollow cylindrical structure, and the outer peripheral wall of the fixing member 110 abuts against the mounting hole on the mounting seat 310. The fixing member 110 can be a sleeve. The fixing member 110 extends through the mounting hole to both sides of the mounting seat 310, the first end of the fixing member 110 is connected to the mounting seat 310, and the second end of the fixing member 110 is detachably connected to the component 400 to be welded. The fixing member 110 can fix the ejection member 120 on the mounting seat 310. The ejection member 120 is a columnar structure. The ejection member 120 can be an ejector pin. The diameter of the accommodating cavity 111 in the sleeve is greater than the diameter of the ejector pin, so that the ejector pin can move along the length direction of the sleeve. The ejection member 120 is located inside the fixing member 110, and one end of the ejection member 120 can extend to the outside of the fixing member 110. The ejection member 120 is slidably connected to the fixing member 110, and the ejection member 120 is used to slide according to the size of the component 400 of different models. That is to say, one end of the pop-up member 120 is connected to the component 400 to be welded, and the other end can extend into or pop out from the accommodating cavity 111 of the fixing member 110 according to the model size of the component 400, so that the mounting seat 310 and the component 400 to be welded are adapted.

[0037] It should be noted that the mounting base 310 may be provided with a plurality of mounting holes, and correspondingly, a plurality of fixing mechanisms 100 may be installed in different mounting holes on the mounting base 310 , so as to accurately fix the component 400 to be welded and prepare for subsequent welding.

[0038] In the embodiment of the present invention, the fixing member 110 is arranged on the mounting seat 310 of the grasping mechanism 300, and the ejecting member 120 can slide on the fixing member 110 according to the height or thickness of the component 400 to be welded, so that the mounting seat 310 can adapt to different types of components 400 to be welded. Compared with the mounting seat 310 in the prior art that cannot adapt to different types of components 400 to be welded, the present invention can avoid replacing the mounting seat 310 or replacing the welding line. The mounting seat 310 directly adapts to different types of components 400 through the fixing mechanism 100, thereby improving the adaptation efficiency of the mounting seat 310 and the component 400 to be welded, so that the grasping mechanism 300 can grasp different types of components 400, which is conducive to improving the working efficiency of the automated welding line.

[0039] In one embodiment of the present invention, Figure 1 As shown, an elastic member 130 is provided inside the sleeve. The elastic member 130 is located in the accommodating cavity 111, that is, the elastic member 130 is located between the inner side wall of the sleeve and the outer peripheral side of the ejector pin. The first end of the elastic member 130 is fixedly arranged on the inner side wall of the sleeve, and the second end of the elastic member 130 is fixedly arranged on the outer peripheral side of the ejector pin. When the second end of the ejector pin slides along the accommodating cavity 111 in the sleeve, the elastic member 130 can be stretched or compressed according to the relative movement distance of the ejector pin and the sleeve, so as to make the sliding connection between the ejector pin and the sleeve more stable.

[0040] In one embodiment of the present invention, Figure 1 As shown, a mounting block 112 is provided on the inner side wall of the sleeve, and a first end of the elastic member 130 is fixedly connected to the mounting block 112 to make the connection between the elastic member 130 and the sleeve more stable.

[0041] In one embodiment of the present invention, Figure 1 As shown, a mounting groove is provided on the outer peripheral side of the ejector pin, and the second end of the elastic member 130 is fixedly connected to the mounting groove, so that the connection between the elastic member 130 and the ejector pin is more stable.

[0042] In one embodiment of the present invention, Figure 1 As shown, the interior of the fixing member 110 is provided with a receiving cavity 111 which passes through the first end and the second end of the fixing member 110, so as to facilitate the ejection member 120 to extend in or out, that is, the ejector pin can be extended in or out from both ends of the sleeve, so as to facilitate the operator to observe the status of the ejector pin.

[0043] In one embodiment of the present invention, Figure 1 As shown, an identification piece (not shown) is provided at one end of the ejector away from the component 400 to display the pressure of the elastic member 130. By providing the identification piece, the adaptation process between the mounting seat 310 and the component 400 to be welded can be displayed, which is helpful for the operation of the automated welding line.

[0044] In one embodiment of the present invention, Figure 1 As shown, the identification member is a scale line, and the scale line is set on the outer peripheral side of the ejector pin. For example, the origin on the scale line indicates the position of the elastic member 130 when it is naturally stretched, and the positive number on the scale line indicates the pressure applied to the elastic member 130 when it is compressed. By recording the pressure when the elastic member 130 abuts against the component 400 to be welded, it is possible to determine whether the fitting of the mounting seat 310 and the component 400 is completed, which is conducive to improving the accuracy of the fitting.

[0045] In one embodiment of the present invention, Figure 1 As shown, the elastic member 130 is a spring. The spring is evenly sleeved on the outer peripheral side of the ejector pin. When the spring is naturally stretched, the pressure on the spring is 0, which is beneficial to prolonging the service life of the elastic member 130.

[0046] Combine the following Figure 3 , to illustrate an embodiment of the present invention. Figure 3 The structure diagram of the mounting base 310 and the fixing mechanism 100 according to an embodiment of the present invention is shown in FIG. Figure 2 .like Figure 1 and Figure 3 As shown, the fixing member 110 further includes a fastener 113. The fastener 113 is sleeved on the outer peripheral side of the sleeve to prevent the sleeve from loosening. The fastener 113 is arranged on the side where the mounting seat 310 contacts the frame 200 (not shown), which is convenient for further fixing the sleeve and preventing the elastic member 130 from sliding the sleeve when it pops out, which is beneficial to improving the overall stability of the fixing mechanism 100.

[0047] In one embodiment of the present invention, the fastener 113 is a nut, the outer peripheral side of the sleeve is provided with threads, and the nut and the sleeve are bolted. In addition, in other embodiments of the present invention, the fastener 113 can also be a rubber structural member, and the present invention does not limit the type of the fastener 113.

[0048] The working principle of the welding auxiliary device disclosed in the embodiment of the present invention is as follows:

[0049] The sleeve is mounted on the mounting seat 310 of the gripping mechanism 300, and the sleeve is further fixed with a fastener 113. When the automated welding line needs to be operated, the mounting seat 310 on the welding line moves as a whole toward the component 400 to be welded, and the ejector pin on the sleeve abuts against the docking port on the component 400 to be welded. The ejector pin slides on the sleeve based on the thickness or height of the component 400 to be welded. The staff reads the scale line at the end of the ejector pin to determine whether the component 400 to be welded and the mounting seat 310 are adapted, thereby achieving adaptation between the mounting seat 310 and components 400 of different models.

[0050] In summary, the welding auxiliary device of the embodiment of the present invention sets the fixing member 110 on the mounting seat 310 of the grasping mechanism 300, and the ejecting member 120 can slide on the fixing member 110 according to the height or thickness of the component 400 to be welded, so that the mounting seat 310 can adapt to different types of components 400 to be welded on the mounting seat 310. The present invention can avoid replacing the mounting seat 310, and the mounting seat 310 directly adapts to different types of components 400 through the fixing mechanism 100, so that the grasping mechanism 300 can grasp different types of components 400, which is conducive to improving the working efficiency of the automated welding line.
