[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Please refer to Figure 1 In an embodiment of the present application, a welding positioning device is provided, which includes a support seat 200, a second clamping member 400 installed on the support seat 200, a first driver 310 and a first clamping member 300 drivingly connected to the first driver 310. The workpiece to be welded is a steel plate, and the workpiece to be welded can also be other workpieces that are convenient to be placed on the top of the support seat 200. The support seat 200 can be fixed in the working area, and the top of the support seat 200 is a flat surface. The support seat 200 is used to place the workpiece to be welded. As a support for the workpiece to be welded, the second clamping member 400 can fix the workpiece to be welded from both sides of the workpiece to be welded. The second clamping member 400 is provided with at least two, and the plurality of second clamping members 400 are respectively located on both sides of the top of the support seat 200, so that the second clamping member 400 can approach the middle from both sides of the workpiece to be welded in the horizontal direction in the figure, and abut against the workpiece to be welded. Clamped and fixed on both sides; the second clamping member 400 can be set to a variety of structural forms, such as strips, blocks, and the second clamping member 400 is manually fixed, such as the second clamping member 400 can be fixed to the support seat 200 by bolts, or the second clamping member 400 can be driven by the second driver 410, such as the clamping part of the second clamping member 400 is connected to the output end of the second driver 410, and the second driver 410 can move in the horizontal direction to drive the clamping part of the second clamping member 400 to clamp the welded part.

[0032] Please refer to Figure 2The first clamping member 300 is installed on the support seat 200. The first clamping member 300 can be connected to the support seat 200 by hinge connection, sliding connection or other methods. The first clamping member 300 is a structure for clamping the surface of the workpiece to be welded. It can be in various forms. For example, the first clamping member 300 adopts a connecting rod mechanism 330, and the connecting rod mechanism 330 is a multi-link structure. The first clamping member 300 is hinged to the support seat 200, or indirectly hinged. The first driver 310 adopts a stepping motor, and the output end of the stepping motor is connected to the first clamping member 300. The connection can be fixed by a conventional method. In the embodiment of the present invention, the first driver 310 can drive the first clamping member 300 to move relative to the support seat 200 to fix the surface of the workpiece to be welded. For example, the support portion of the first clamping member 300 is plate-shaped, and the first driver 310 is arranged inside or on the side of the support seat 200. The first driver 310 drives the first clamping member 300 to rotate relative to the support seat 200 through the output end, so that the first clamping member 300 can cover the surface of the workpiece to be welded away from the support seat 200, such as the first clamping member 300 covers the workpiece to be welded as a whole and abuts against the top of the support seat 200. The above-mentioned welding positioning device can be used in the production process of railway freight cars, and can ensure that the positions of various components of the steel structure are accurate during welding, avoid the warping of the steel plate and affect the subsequent welding, thereby improving the welding quality and accuracy. At the same time, since the second clamping member 400 can move within a certain range in the horizontal direction, the first clamping member 300 can move at a certain position above the workpiece to be welded, so that the device has good adaptability and can meet the welding requirements of workpieces to be welded of different shapes and sizes.

[0033] The positioning device of the prior art is not stable enough after fixing the steel plate during use. Such positioning device positioning can easily cause the steel plate to warp, which has a certain impact on the welding of the steel plate and reduces the stability of the steel structure. However, the present application fixes the parts to be welded on both sides of the parts to be welded by the second clamping member 400. Since the parts to be welded are placed on the support seat 200, the space is vacated by the rotation of the first clamping member 300. After the parts to be welded are placed, the first clamping member 300 is used to cover the surface of the parts to be welded. In this way, the surface of the parts to be welded is clamped and fixed by the support seat 200 and the first clamping member 300. The parts to be welded are fixed from both sides and the surface direction. In this way, the fixed parts to be welded will not deviate from the position during welding, which can ensure that the position of the parts to be welded is accurate during welding, and the error is controlled within a very small range. It has a high positioning accuracy, thereby improving the welding quality and accuracy, improving the stability of the structural fixation, and ensuring the integrity of the welding structure.

The drawer box 590 can be provided with a handle for easy operation. When the drawer box 590 is pulled out, the particles in the collection box 580 can be transferred for regular cleaning.

[0042] Specifically, after the steel structure welding positioning device is used, the fan 540 is started, and the suction force generated by the fan 540 is used to absorb the debris generated by the steel plate welding. The absorbed debris is transmitted to the drawer 590 in the collection box 580 through the conveying pipe 570, and then the third driver 550 is started, and the slider 530 is driven to slide on the slide bar 520 by its output end, and the sliding of the slider 530 is used to drive the fan 540 to move synchronously, and the debris attached to the surface of the equipment is fully absorbed and cleaned. The fan 540 is driven to move synchronously by the movement of the slider 530, and the fan 540 is used to absorb the debris and dust on the surface of the support seat 200, and then transmitted to the drawer 590 inside the collection box 580 through the conveying pipe 570, so as to realize the all-round and dead-angle collection and cleaning of debris and dust, solve the problem that the cleaning process of traditional equipment is relatively cumbersome, simplify the cleaning process, and improve the cleaning efficiency of the device.
