DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0029] The top product is generally positioned by tooling, and then welding is achieved by contacting the product with the upper and lower anodes at the same time. However, due to the different sizes of products and the fixed sizes of existing tooling, when dealing with products of different specifications in the same series, it is often necessary to manufacture applicable tooling of various specifications, which increases the cost of use.

[0030] In view of the above technical problems, the present application provides a welding fixture. Figure 1 The overall structural diagram of the welding fixture is shown; Figure 1 In the figure, the welding fixture comprises an adjustable support member 100 for forming a support for a workpiece; a lifting member 200 for lifting the workpiece; and a pre-pressing member 300 for pre-pressing the workpiece.

[0031] Figure 2 shows a schematic structural diagram of an adjustable support member 100; Figure 2 In the embodiment, the adjustable support member 100 comprises:

[0032] A fixed disc 110 is disposed directly below the workpiece, and a plurality of linear slideways 111 are evenly arranged on the upper surface of the fixed disc 110;

[0033] The driving disc 120 is rotatably connected to the upper portion of the fixed disc 110. A plurality of arc-shaped slideways 121 are evenly arranged on the driving disc 120. An extension arm 122 is provided on the curved surface of the driving disc 120.

[0034] The slide bar 130 is slidably connected in the linear slide 111. The slide bar 130 passes through the arc slide 121. The number of the linear slide 111, the arc slide 121 and the slide bar 130 corresponds. A support column 131 is provided on the top of the slide bar 130. The support column 131 is conical in design with a narrow upper part and a wide lower part.

[0035] It should be noted that if Figure 2 As shown, since there are three groups of evenly distributed through holes on the workpiece, the number of the linear slides 111, the arc slides 121 and the slide rods 130 in this embodiment are all set to three groups. In some other embodiments, the number of the linear slides 111, the arc slides 121 and the slide rods 130 can be set according to specific needs.

[0036] During use, the positions of the three groups of slide bars 130 are adjusted according to the size of the workpiece, and the extension arm 122 is manually driven to drive the drive disc 120 to rotate around its center. The slide bar 130 is restricted by the arc-shaped slide 121, so that the slide bar 130 can be driven to slide along the trajectory of the straight slide 111, thereby adjusting the positions of the three groups of slide bars 130 to match the positions of the through holes on the workpiece, and the design of the support column 131 can cope with through holes of different sizes, thereby forming support for the workpiece. In the present application, the slide bar 130 can form a stable support for the workpiece, and through the centripetal adjustment of multiple groups of slide bars 130, it can be applied to workpieces of different specifications in the same series, so as to improve the applicability of the device and reduce production costs.

[0037] It should be noted that when the workpiece is installed, the upper anode 140 and the lower anode 150 are respectively contacted with the upper and lower end surfaces of the workpiece to complete the welding of the workpiece. This is the existing technology and will not be elaborated here.

[0038] It should be noted that the extension arm 122 is a manually used driving arm. In some automated structures, a driving motor or the like can also be used to drive the rotation of the driving disc 120 . The specific setting can be made according to the needs.

[0039] Figure 3 FIG. 2 shows a schematic structural diagram of a lifting member 200. Figure 3 In the embodiment, the lifting member 200 comprises:

[0040] A first hydraulic cylinder 210;

[0041] The lifting plate 220 is installed at the output end of the first hydraulic cylinder 210 , and a reserved groove 221 for the sliding rod 130 to pass through is formed on the lifting plate 220 .

[0042] During use, before the workpiece is installed, the first hydraulic cylinder 210 is started to drive the lifting plate 220 to move downward so that the lifting plate 220 is located below the workpiece. When the workpiece is welded, the first hydraulic cylinder 210 is started again to drive the lifting plate 220 to move upward. At this time, the lifting plate 220 can lift the workpiece and separate the workpiece from contact with the slide bar 130, which facilitates the replacement of the workpiece and improves the efficiency of continuous welding.

[0043] Figure 4 A schematic structural diagram of a pre-pressed component 300 is shown; Figure 4 In the embodiment, the pre-press 300 comprises:

[0044] An “L”-shaped support rod 310 is installed above the jacking plate 220;

[0045] The second hydraulic cylinder 320 is installed above the "L"-shaped support rod 310, and the output end of the second hydraulic cylinder 320 penetrates the "L"-shaped support rod 310 and faces downward;

[0046] The pressing plate 330 is connected to the output end of the second hydraulic cylinder 320 , and the lower end surface of the pressing plate 330 matches the workpiece.

[0047] During use, when the workpiece is installed above the slide bar 130, in order to ensure the stability of the workpiece during welding, the second hydraulic cylinder 320 can be started to drive the pressing plate 330 to move downward, and cooperate with the slide bar 130 to press the workpiece to avoid shaking of the workpiece during welding, thereby ensuring the welding effect.

[0048] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
