[0005] Preferably, four pads are provided on the bottom plate, and the four pads are provided with limiting grooves.

[0006] The beneficial effects of the present invention are: the device fixes the front connecting plate through the quick clamp, positions the pull rod through the front support plate of the pull rod, positions the support plate through the limit support plate, and positions the hook through the hook limit plate. Each part is positioned and fixed, and the mounting bracket can be accurately limited together before welding, which greatly improves the welding accuracy and ensures the welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural schematic diagram of the present invention;

[0008] Figure 2 is a three-dimensional diagram of the connecting rod in the present invention;

[0009] Figure 3 This is the application diagram of this device. DETAILED DESCRIPTION

[0010] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between one device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0011] like Figure 1-Figure 3 As shown, a connecting rod welding device includes a base plate 1, a quick clamp 2, a front connecting plate support plate 3, a pull rod front support plate 4, a limit plate support plate 5, a limit plate side baffle 6, a limit plate side block 7 and a hook limit plate 8; the quick clamp is installed on the left side of the base plate to press the front connecting plate, the front connecting plate support plate is two pieces, which are respectively fixed on the left side of the base plate, the front connecting plate support plate is provided with a front connecting plate positioning groove 9, the pull rod front support plate is transversely fixed between the front connecting plate support plates, the two sides of the pull rod front support plate are provided with U-shaped grooves 10, the There are two limit plate support plates, which are fixed in the middle of the bottom plate. The limit plate side baffle is transversely fixed between the two limit plate support plates. The limit plate side baffle is hinged on one side of the limit plate side baffle. The hook limit plate is divided into two groups, each with two plates. The two groups of hook limit plates are connected together by a connecting plate 11. The two ends of the connecting plate are provided with baffles 12 for limiting the side of the hook. The upper part of the hook limit plate is provided with an arc-shaped protrusion 13 that cooperates with the inner side of the hook. The distance between the two arc-shaped protrusions is greater than the distance between the two U-shaped grooves. Four pads 14 are provided on the bottom plate, and the four pads are provided with limit grooves 15.

[0012] When in use, the following steps are included: Step 1, place a limit plate on the limit plate support plate and press it with a quick clamp, then place the left pull rod and the right pull rod into the U-shaped groove and the limit groove, and press the limit plate at the bottom in the middle;
