Technical Field

[0001] This utility model relates to the field of positioning seat technology, and in particular to a positioning seat structure for a welding machine. Background Technology

[0002] Steel drums are packaging containers made of steel, characterized by high strength, corrosion resistance, and reusability. They are widely used in industrial product packaging, transport packaging, and sales packaging. The body of a steel drum is welded from rolled metal sheets. Before welding, the welding machine needs to position the two ends of the rolled metal sheet to be welded, ensuring that the two ends are aligned.

[0003] In the prior art, a feeding, transferring, welding, and unloading device for welding barrel plates, disclosed in CN114309921A, specifically discloses the positioning process before welding as follows: "The base 311 supports and fixes the rolled barrel plate, and the first clamping member drive 3122 and the second clamping member drive 3124 in the clamping mechanism 312 simultaneously drive the first arc-shaped clamping member 3121 and the second arc-shaped clamping member 3123 to move horizontally towards each other to clamp the rolled barrel plate, so that the first end 03 to be welded is located in the space between the lower end face of the first positioning pressure plate 3146 and the top surface of the moving seat 3141, and due to the clamping force, the first end 03 to be welded abuts against the first positioning pressure plate 3146." On the side of the second positioning plate 3148, the second end 04 to be welded is located in the space between the lower end face of the second positioning plate 3148 and the top surface of the fixed seat 3143, and due to the clamping force, the second end 04 to be welded abuts against the side of the moving seat 3141; at this time, the end faces of the first end 03 to be welded and the second end 04 to be welded are in the same vertical plane. 2-b As shown in Figure B of Figure 15, the second positioning plate driving member 3149 in the thickness alignment mechanism 314 drives the second positioning plate 3148 to press down; at this time, the second positioning plate 3148 presses down and at the same time, it also drives the first positioning plate 3146 to press down a small distance. 2-c As shown in Figure 15C, the moving seat drive member 3142 in the thickness alignment mechanism 314 drives the moving seat 3141 to descend, at which point the top surface of the moving seat 3141 is flush with the top surface of the fixed seat 3143. 2-d As shown in Figure 15D, the first positioning plate drive member 3147 in the thickness alignment mechanism 314 drives the first positioning plate 3146 to press down. 2-e As shown in Figure 15E, several first fixed plate drive members 3151 and several second fixed plate drive members 3153 in the thickness alignment mechanism 314 simultaneously drive several first fixed plates 3150 and several second fixed plates 3152 to press down, fixing the positioning plates. The first end 03 and the second end 04 to be welded are waiting for welding assembly 32 to weld; the first positioning pressure plate drive 3147 and the second positioning pressure plate drive 3149 respectively drive the first positioning pressure plate 3146 and the second positioning pressure plate 3148 to reset; the oblique drive 3155 drives the first positioning pressure plate drive module and the second positioning pressure plate drive module to reset. In this patent document, the positioning process of the two ends to be welded of the rolled metal plate by the moving seat 3141 and the fixed seat 3143 in conjunction with a number of first fixed pressure plates 3150 and a number of second fixed pressure plates 3152 is relatively complicated.

[0038] The present invention will be further described in detail below with reference to specific embodiments:

[0039] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0040] like Figures 1-5As shown, a positioning seat structure for a welding machine is used to position the two ends of a rolled cylindrical barrel 23 to be welded, in conjunction with a left pressure plate 18, a right pressure plate 19, a left clamping member 20, a right clamping member 21, and a support seat 22. It includes a main beam 1, located away from the loading side of the rolled cylindrical barrel 23 (i.e., the side away from the loading side of the rolled cylindrical barrel 23). Figure 1 When the direction is used as a reference, Figure 1 One end of the main beam 1 is fixed to the frame, and the other end is a free cantilever end; the left movable seat 2 and the right movable seat 3 are symmetrically slidably installed on the top surface of the main beam 1, and the sliding direction is parallel to the width direction of the main beam 1; the left card seat 24 and the right card seat 25 are symmetrically arranged, the left card seat 24 is located on the right side below the left movable seat 2 and fixed on the main beam 1, and the right card seat 25 is located on the left side below the right movable seat 3 and fixed on the main beam 1; the positioning plate assembly is installed between the left movable seat 2, the left card seat 24 and the right movable seat 3, and the right card seat 25; a first elastic element is installed between the left movable seat 2 and the left card seat 24, and a second elastic element is installed between the right movable seat 3 and the right card seat 25; in this embodiment, as Figures 3-5 As shown, the first elastic element is the first spring 4, and the second elastic element is the second spring 5. When there is no external force, the left movable seat 2 is located at the leftmost end of its travel. The function of the first spring 4 is to drive the left movable seat 2 back to the leftmost end of its travel. When there is no external force, the right movable seat 3 is located at the rightmost end of its travel. The function of the second spring 5 is to drive the right movable seat 3 back to the rightmost end of its travel. A left limiting element is installed on the main beam 1 to limit the travel of the left movable seat 2 to the left, and a right limiting element is installed on the main beam 1 to limit the travel of the right movable seat 3 to the right.

[0041] The left movable seat 2 is slidably mounted on the main beam 1 via the first linear guide rail 6; the right movable seat 3 is slidably mounted on the main beam 1 via the second linear guide rail 7. The positioning plate assembly includes a positioning vertical plate 8 and a drive component mounted on the main beam 1 to drive the positioning vertical plate 8 to rise and fall. The top surface of the left movable seat 2 is a first arc surface that matches one end of the rolled cylindrical body 23 to be welded; the top surface of the right movable seat 3 is a second arc surface that matches the other end of the rolled cylindrical body 23 to be welded. When the left moving seat 2 is at its maximum stroke furthest from the right moving seat 3, there is a gap between the edge of the first arc surface of the left moving seat 2 near the positioning vertical plate 8 and the positioning vertical plate 8 in the raised state; thus, when the left pressure plate 18 presses one end of the rolled barrel 23 onto the left moving seat 2, a portion of the end to be welded is exposed outside the left pressure plate 18 and the left moving seat 2 for welding by the welding gun; when the right moving seat 3 is at its maximum stroke furthest from the left moving seat 2, there is a gap between the edge of the second arc surface of the right moving seat 3 near the positioning vertical plate 8 and the positioning vertical plate 8 in the raised state; thus, when the right pressure plate 19 presses the other end of the rolled barrel 23 onto the right moving seat 3, a portion of the other end to be welded is exposed outside the right pressure plate 19 and the right moving seat 3 for welding by the welding gun.

[0042] The left retaining seat 24 is provided with a left step 10 for limiting the travel of the left movable seat 2 to the right, and the left movable seat 2 is recessed in the left step 10 with a left groove 11. The right retaining seat 25 is provided with a right step 12 for limiting the travel of the right movable seat 3 to the left, and the right movable seat 3 is recessed in the right step 12 with a right groove 13. The left movable seat 2 has a first mounting hole on the side opposite to the left retaining seat 24, and the left retaining seat 24 has a second mounting hole corresponding to the first mounting hole. A first elastic element is installed in the first mounting hole and the second mounting hole. The right movable seat 3 has a third mounting hole on the side opposite to the right retaining seat 25, and the right retaining seat 25 has a fourth mounting hole corresponding to the third mounting hole. A second elastic element is installed in the third mounting hole and the fourth mounting hole.

[0043] The left limiting component is a left baffle 14, which is fixed at the leftmost end of the width direction of the main beam 1; the right limiting component is a right baffle 15, which is fixed at the rightmost end of the width direction of the main beam 1. A left slot 16 is formed on the top surface of the left movable seat 2, near the feeding side of the rolled cylindrical body 23; a right slot 17 is formed on the top surface of the right movable seat 3, near the feeding side of the rolled cylindrical body 23. The driving component is a lifting cylinder 9, whose cylinder body is fixed to the bottom surface of the main beam 1. The piston cylinder of the lifting cylinder 9 penetrates the main beam 1 but does not contact it. The main beam 1 has a through hole in a vertical direction through which the piston rod of the lifting cylinder 9 passes.

[0044] The working principle of the positioning seat structure of a welding machine in this utility model is as follows: In the initial state, the positioning vertical plate 8 is located at the highest point of its lifting stroke, that is, in the rising state; the left moving seat 2 is located at the leftmost end of its stroke; the right moving seat 3 is located at the rightmost end of its stroke; the left pressure plate 18 is located at the leftmost end of its left and right strokes and is in a raised state; the right pressure plate 19 is located at the rightmost end of its left and right strokes and is in a raised state; the left clamping member 20 and the right clamping member 21 are in an open state. Upon starting the operation, step one: the rolled cylindrical body 23 is pushed into the support seat 22 of the welding machine. The left clamping member 20 and the right clamping member 21, located on the left and right sides of the rolled cylindrical body 23, clamp the rolled cylindrical body 23 under the drive of the left clamping drive member and the right clamping drive member, so that the two ends of the rolled cylindrical body 23 to be welded abut against the two side walls of the positioning vertical plate 8, achieving the desired effect. Figure 6 As shown in the diagram; Step 2: The left pressure plate pressing drive drives the left pressure plate 18 to press down, and the right pressure plate pressing drive drives the right pressure plate 19 to press down. The left pressure plate 18 presses one end to be welded onto the left movable seat 2, and the right pressure plate 19 presses the other end to be welded onto the right movable seat 3. The lifting cylinder 9 drives the positioning vertical plate 8 to descend, achieving the desired state. Figure 7 As shown in the figure; Step 3: The left clamping member 20 and the right clamping member 21 loosen the rolled cylindrical body 23. The left hook claw (not shown in the figure) is driven by the left hook claw pressing drive to lock the left slot 16 of the left moving seat 2. The left pressure plate pressing drive, the left pressure plate 18, the left hook claw pressing drive, and the left hook claw are all installed on the left mounting plate. The left horizontal drive drives the left mounting plate to move to the right, thereby driving the left pressure plate 18 and the left moving seat 2 to move to the right. At the same time, the right hook claw (not shown in the figure) is driven by the right hook claw pressing drive to lock the right slot 17 of the right moving seat 3. The right pressure plate pressing drive, the right pressure plate 19, the right hook claw pressing drive, and the right hook claw are all installed on the right mounting plate. The right horizontal drive drives the right mounting plate to move to the left, thereby driving the right pressure plate 19 and the right moving seat 3 to move to the left. This makes the two ends of the rolled cylindrical body 23 to be welded aligned, achieving the desired result. Figure 8 The state shown is used to complete the positioning of the two ends of the rolled barrel 23 before welding, and to wait for the welding gun to weld. After welding is completed, each mechanism is reset.
