[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The utility model discloses a welding tool, which is used in pairs. The paired welding tools are used to be respectively fixed to the two ends of a workpiece 5 and then connected to an automatic welding device, so that the workpiece 5 is installed on the automatic welding device and the position and posture are adjusted with the automatic welding device, so as to realize automatic welding of the workpiece 5.

[0036] The welding tool of the utility model comprises a frame 1, a centering clamping device 2, a vertical adjustment device 3, and a pressing device 4.

[0037] The frame 1 is used for fixed connection with the automatic welding equipment, and can move in the lateral direction with the automatic welding equipment, adjust the distance between the paired welding tools to adapt to the length of the workpiece 5, and adapt the workpiece 5 to be placed between the paired welding tools; the fixed connection between the frame 1 and the automatic welding equipment enables the automatic welding equipment to drive the welding tooling and the workpiece 5 to rotate around the lateral axis.

[0038] The vertical adjustment device 3 is connected to the frame 1, and includes a vertical limit assembly, which includes a supporting member 36 and a vertical limit member 31 located above the supporting member 36, and a gap is provided between the supporting member 36 and the vertical limit member 31, which is used to place the end of the workpiece 5 and support the workpiece 5 and limit the workpiece 5 in the vertical direction to prevent the workpiece 5 from moving a large distance in the vertical direction. The position of the vertical limit assembly in the vertical direction is adjustable.

[0039] The centering clamping device 2 is connected to the frame 1, and includes a pair of clamping members 21, which are correspondingly arranged in the longitudinal direction and can move toward or away from each other at a constant speed in the longitudinal direction at the same time; when the corresponding clamping members 21 move toward each other, the position of the workpiece 5 located therebetween is adjusted and clamped, so that the workpiece 5 moves to the middle position of the corresponding clamping members 21 and is fixed between the corresponding clamping members 21, thereby realizing the adjustment of the position of the workpiece 5 in the process of clamping and fixing the workpiece 5.

[0040] The adjustment of the vertical limit assembly position in the vertical direction is used to adapt to the height of the corresponding clamping member 21, so that different types of workpieces 5 can be shared by welding tooling even if the height of the clamping position of the clamping member 21 and the height of the supporting position of the vertical limit assembly are different; that is, the adaptability of the welding tooling is improved.

[0041] The clamping device 4 includes a clamping member 41, which is a long structure, arranged horizontally, and located above the supporting member 36. The middle part is rotatably connected to the vertical limit member 31, and the rotating axis is in the longitudinal direction; the other end of the clamping member 41 can move in the vertical direction, so that one end of it can clamp the workpiece 5 or release the clamping force on the workpiece 5.

[0042] The welding tool of the present invention automatically adjusts the position of the workpiece 5 by the clamping parts 21 of the centering clamping device 2 that move toward each other at a constant speed, so that the workpiece 5 is adjusted to the middle of the longitudinal direction of the tool and is tightened and fixed, thereby improving the degree of automation of fixing the workpiece 5 and the accuracy of the fixed position, thereby improving the efficiency of installing the workpiece 5 on the welding tool; in addition, for workpieces 5 that are treated by special processes, such as heat treatment, the position of the workpiece 5 is automatically adjusted to improve the safety of installing the workpiece 5 on the welding tool.

[0043] The welding tool of the utility model adjusts the position of its vertical limit assembly in the vertical direction through the vertical adjustment device 3, thereby solving the adaptability problem caused by the different heights of the parts of workpieces 5 installed in the vertical limit assembly relative to the clamping position of the clamping member 21, improving the adaptability of the welding tool, and making it possible to switch between workpieces 5 of different models for welding without replacing the welding tool, and only need to adjust the position of the vertical limit assembly in the vertical direction, thereby improving production efficiency; reducing the types of welding tools equipped for multiple models of workpieces 5, and reducing production costs.

[0044] The specific structure and principle of the welding tool of the present invention are described in detail below through specific embodiments.

[0045] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The centering clamping device 2 also includes a first driving member 22 , a first lead screw 23 , and a first guide rail 24 .

[0046] The first driving member 22 and the first guide rail 24 are fixedly connected to the frame body 1 respectively; the first lead screw 23 is longitudinally arranged, connected to the first driving member 22, and driven by the first driving member 22 to rotate around its axis.

[0047] The first lead screw 23 is divided into two sides with threads of equal pitch and opposite directions with the middle thereof as the boundary; each clamping member 21 is formed with a screw hole adapted to the threaded connection of the first lead screw 23, and is threadedly connected to the first lead screw 23; each clamping member 21 is formed with a structure that can be slidably mounted on the first guide rail 24, and is slidably mounted together with the first guide rail 24; when the first driving member 22 drives the first lead screw 23 to rotate, the corresponding clamping members 21 move toward or away from each other.

[0048] The welding tooling of this embodiment forms a thread with equal pitch on the first screw 23, so that when the clamping member 21 is in the middle position relative to the initial position and is located in the middle position of the longitudinal position of the frame 1, the middle position of the corresponding clamping member 21 that moves at the same time is always located in the middle position of the frame 1, thereby achieving the goal of clamping the workpiece 5 in the longitudinal direction and adjusting the position of the workpiece 5 in the longitudinal direction so that it is located in the middle of the frame 1 with high efficiency.

[0049] In some specific embodiments, the first driving member in the centering clamping device can have a bidirectional output; the first lead screw can be a lead screw with two threads in opposite directions and the same pitch, which are respectively connected to the outputs of the first driving member in two directions, so as to realize the equal-speed movement of the paired clamping members toward or away from each other.

[0050] In some specific embodiments, there may be two first driving members and two first lead screws, which respectively include same-direction or opposite-direction threads; and each first lead screw is longitudinally arranged adjacent to each other end to end; each first driving member is respectively connected to each first lead screw, and respectively drives each first lead screw to rotate in the same direction or opposite direction; thereby realizing the corresponding clamping members moving toward or away from each other at the same speed.

[0051] Of course, the clamping member can be a threaded connection member connected to the first lead screw, a sliding connection member slidably connected to the first guide rail, or a clamping portion for clamping the workpiece 5, which are relatively fixedly connected together.

[0052] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The first driving member 22 is a servo motor, which is convenient for controlling the stroke and the running direction and has high precision.

[0053] Of course, the first driving member 22 may also be other rotationally driven driving devices, such as a stepping motor, a common motor, a hydraulic motor, etc.

[0054] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The vertical adjustment device 3 also includes a second driving member 32 , a second lead screw 33 , a second guide rail 35 , and a slider 34 .

[0055] The second driving member 32 and the second lead screw 33 are respectively connected to the frame 1; the second driving member 32 is fixed relative to the frame 1; the second lead screw 33 can rotate around its axis relative to the frame 1; the second lead screw 33 is connected to the second driving member 32 and is driven to rotate by the second driving member 32.

[0056] The slider 34 is formed with a screw hole adapted to be threadedly connected to the second lead screw 33, and is threadedly connected to the second lead screw 33; the slider 34 is slidably connected to the second guide rail 35, so that the slider 34 can move along the second guide rail 35; the second driving member 32 drives the second lead screw 33 to rotate around its axis, and during the rotation of the second lead screw 33, the slider 34 is driven to move along the second guide rail 35 through the thread, so that the slider 34 drives the vertical position of the vertical adjustment component to be adjusted.

[0057] The welding tool of this embodiment realizes the adjustment of the position of the vertical limit assembly fixedly connected to the slider 34 in the vertical direction through the cooperation of the second lead screw 33, the slider 34 and the second driving member 32, which is simple and efficient.

[0058] Of course, the slider 34 can be a component in which a threaded connector threadedly connected to the second lead screw 33 and a sliding connector slidably connected to the second guide rail 35 are fixedly connected together.

[0059] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The second driving member 32 is a servo motor, which improves control accuracy and efficiency.

[0060] Of course, the second driving member 32 may also be other rotation driving devices, such as a stepping motor, a common motor, a hydraulic motor, etc.

[0061] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The clamping device 4 also includes a third driving member 42, which is rotatably connected to the slider 34 and includes a moving end; the moving end is rotatably connected to the other end of the clamping member 41, and can generate displacement in the vertical direction, so that the clamping member 41 rotates around the central axis in the vertical plane space, thereby causing one end of the clamping member 41 to clamp the workpiece 5 located in the vertical limiting assembly, or release the clamping force on the workpiece 5.

[0062] The welding fixture of this embodiment drives the pressing member 41 to rotate through the third driving member 42 connected to the slider 34, and one end of the pressing member 41 presses the workpiece 5 through the lever principle, which is highly efficient.

[0063] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The third driving member 42 is a hydraulic cylinder, which improves the reliability and stability of the clamping force applied by the clamping member 41 on the workpiece 5.

[0064] Of course, the third driving member 42 can be other driving devices with linear displacement, such as an electric push rod, a hydraulic push rod, a pneumatic push rod, a cylinder, etc.

[0065] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 , Figure 7 The frame 1 includes a connecting portion 11 of a disc structure; a plurality of through holes 111 are formed along the outer circumference of the connecting portion 11, whose axes tend to be parallel to the axis of the connecting portion 11, for fixed connection with automatic welding equipment by bolts.

[0066] The welding fixture of this embodiment arranges the connecting part 11 into a disc shape and arranges each through hole 111 on the outer circumference of the connecting part 11, so that the shear force on the bolts when the automatic welding equipment rotates is evenly distributed among the bolts, thereby improving the stability and reliability of the connection between the welding fixture and the automatic welding equipment.

[0068] The welding jig of this embodiment is arranged in the middle of the longitudinal direction of the connection part 11 by the limiting component so that the workpiece 5 is fixed on the welding jig. When the welding jig is connected to the automatic welding equipment, the middle of the workpiece 5 in the longitudinal direction tends to be located on the rotating shaft of the rotating device of the automatic welding equipment, thereby reducing the difficulty and power of rotation, improving the rotation efficiency and reducing energy consumption.

[0069] In some specific embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The welding equipment also includes a controller and a first sensor and a second sensor connected to the controller; the first sensor and the second sensor are respectively arranged on the clamping member 21 and the pressing member 41, and are used to detect the clamping force and the pressing force and transmit them to the controller. The controller controls the action of the first driving member 22 and the third driving member 42 according to the received clamping force and the pressing force.
