Furthermore, existing fixtures are not flexible enough when clamping thin-walled sheet metal parts of different sizes and shapes, requiring frequent fixture changes, which increases production costs and production cycles.

[0006] The purpose and effect of this utility model, a multi-station thin-walled sheet metal welding fixture, are achieved by the following specific technical means:

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a multi-station thin-walled sheet metal welding fixture, comprising: a base 1; the base 1 adopts a rectangular plate structure, and the top of the base 1 has a circular through-slot structure in a rectangular array, and the bottom of the base 1 has a rectangular sliding groove structure; a set of first slide rails 103 are fixedly arranged on both sides of the top of the base 1; a set of rectangular block structure sliders 106 are slidably arranged on both sides between the two sets of first slide rails 103, and the bottom of the sliders 106 has a through-hole structure; a U-shaped plate structure connecting shaft 111 is arranged and rotatably arranged on the top of the sliders 106; a first gear 112 is fixedly arranged on the outer side of the bottom of the connecting shaft 111; a first cylinder 113 is rotatably arranged on the top of the connecting shaft 111; a second gear 114 is fixedly arranged on the outer end of the rotating shaft of the first cylinder 113; a set of clamping arms 115 are rotatably connected to both sides of one end of the first cylinder 113.

[0025] The first slide rail 103 has a rotatable double-acting screw 104 rotatably mounted on its inner side, and the double-acting screw 104 is connected to two sets of sliders 106 by a threaded connection. A first motor 105 is fixedly mounted on one side of the first slide rail 103, and the first motor 105 is connected to the double-acting screw 104 by transmission. The first motor 105 drives the double-acting screw 104 to rotate, and the two sets of sliders 106 slide towards or away from each other on the first slide rail 103 by threaded transmission, thereby adjusting the distance between the sliders 106 to accommodate thin-walled sheet metal parts of different widths. A second slide rail 107 is fixedly mounted on the top of the sliders 106. A screw 108 is rotatably mounted on the inner side of the second slide rail 107. A second motor 109 is fixedly installed on one side of the second slide rail 107, and the second motor 109 is connected to the screw 108 for transmission. A first rack 110 is slidably installed on the top of the second slide rail 107, and the first rack 110 is connected to the first rack 110 by thread engagement. The first rack 110 is meshed with the first gear 112. The second motor 109 drives the screw 108 to rotate, causing the first rack 110 to slide on the second slide rail 107. Then, through the meshing transmission with the first gear 112, the connecting shaft 111 is rotated, and the angle of the clamping arm 115 in the horizontal direction is adjusted to meet the needs of adjusting the welding angle of the sheet metal parts during the welding process.

[0026] The first cylinder 113 has a rectangular plate structure connecting block 116 on its front drive connection. The two sides of the connecting block 116 are rotatably connected to two sets of clamping arms 115 respectively. Under the action of the first cylinder 113, the connecting block 116 drives the clamping arms 115 to perform opening and closing actions, thereby clamping and releasing the thin-walled sheet metal parts.

[0027] The slider 106 has a cylindrical slide rod 117 fixedly mounted on one side of its top. A rectangular slide plate 118 is slidably mounted on the outside of the slide rod 117. A second rack 119 is fixedly mounted on the bottom of the slide plate 118 and meshes with a second gear 114. A second cylinder 120 is fixedly mounted on one side of the top of the slider 106 and is connected to the slide plate 118. The second cylinder 120 drives the slide plate 118 to slide on the slide rod 117. Through the meshing transmission of the second rack 119 and the second gear 114, the angle of the first cylinder 113 and the clamping arm 115 in the vertical direction is adjusted to ensure the precise clamping of the thin-walled sheet metal parts during the welding process, thus meeting different production needs.

[0028] The specific usage and function of this embodiment are as follows:

[0029] The sheet metal parts to be welded are placed between the two sets of clamping arms 115. The first cylinder 113 is operated, which drives the clamping arms 115 to open and close via the connecting block 116, activating the clamping function of the first cylinder 113. The clamping force is slowly increased until the thin-walled sheet metal parts are firmly clamped, and the two sets of sheet metal parts are respectively clamped between the left and right clamping arms 115. Then, the clamping angle of the first cylinder 113 is adjusted according to the welding requirements. The second motor 109 is started, which drives the screw 108 to rotate, causing the first rack 110 to slide on the second slide rail 107. The first rack 110 meshes with the first gear 112 to achieve the rotation of the connecting shaft 111, thereby adjusting the angle of the clamping arms 115 in the horizontal direction and adjusting the vertical angle. When the second cylinder 120 is activated, it drives the sliding plate 118 to slide on the slide rod 117. The second rack 119 at the bottom of the sliding plate 118 meshes with the second gear 114 to achieve vertical angle adjustment of the first cylinder 113 and the clamping arm 115. After the adjustment is completed, the distance between the two sets of workpieces can be adjusted according to the size of the workpiece. By starting the first motor 105, the bidirectional lead screw 104 is driven to rotate, thereby synchronously driving the two sets of sliders 106 on both sides to move towards each other, so that the workpiece reaches the required production station, and welding production can be carried out. In the whole process, the welding angle of multiple stations can be adjusted synchronously to meet the welding operation needs under different angles, which greatly improves the efficiency of welding operations and the practicality of products.

[0030] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown:

[0031] The base 1 has a rectangular groove at the bottom of the base 1, which is slidably connected to a set of rectangular groove structure placement slots 101; and an exhaust fan 102 is fixedly installed on the top of the base 1.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, while welding, ice blocks or other low-temperature objects can be placed in the placement groove 101, and then the exhaust fan 102 can be turned on to draw the cool air generated by the low-temperature objects upwards. This can quickly cool down the welding part of the workpiece, reduce the risk of workpiece deformation, and at the same time quickly remove harmful gases generated during the welding process, which helps to maintain the health of the working area environment and reduce harm to the human body.
