Description

Technical Field

[0001] This utility model relates to the field of spot welding equipment technology, and in particular to an adaptive spot welding device. Background Technology

[0002] In industrial spot welding operations, the size and shape of the workpieces to be welded vary widely, and some workpieces require spot welding at an angle. Traditional spot welding equipment often has a fixed clamping mechanism, which cannot flexibly adjust the clamping distance to adapt to workpieces of different widths, and lacks an effective support and protection structure, making the workpiece prone to displacement or deformation during spot welding. At the same time, the angle adjustment of the welding head of traditional spot welding equipment is limited, making it difficult to meet the spot welding requirements of different tilt angles, resulting in low positioning accuracy, which in turn affects welding quality and work efficiency, and cannot adapt to diverse spot welding operation scenarios. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides an adaptive spot welding device. This device can adaptively position and perform multi-angle spot welding operations according to workpieces of different specifications, significantly improving the adaptability, stability, processing efficiency, and accuracy of spot welding operations.

[0004] To achieve the above objectives, this utility model provides an adaptive spot welding device, including a mounting main board. A first guide rail and a second guide rail are vertically and parallelly arranged on the mounting main board. An auxiliary clamping mechanism is slidably connected to the first guide rail for clamping and fixing the workpiece to be welded. A first driving cylinder assembly is mounted on the side end of the first guide rail, and the output end of the first driving cylinder assembly is connected to the auxiliary clamping mechanism. The first driving cylinder assembly is driven to move the auxiliary clamping mechanism up and down on the first guide rail. A spot welding mechanism is slidably connected to the second guide rail, and a second driving cylinder assembly is mounted on the side end of the second guide rail. The output end of the second driving cylinder assembly is connected to the spot welding mechanism, and the second driving cylinder assembly is driven to move the spot welding mechanism up and down on the second guide rail, thereby realizing adaptive positioning spot welding of the workpiece.

[0005] In operation, the workpiece to be welded is first placed in the corresponding area of ​​the auxiliary clamping mechanism on the mounting motherboard. Then, the first drive motor operates, moving the clamping hand in the opposite direction, clamping and fixing the workpiece using the anti-slip pads on the inside of the clamping hand. Simultaneously, the second drive motor in the auxiliary lifting assembly drives the connecting block to adjust its position, causing the lifting block at the top of the connecting rod to adaptively conform to the bottom of the workpiece under the elastic action of the spring, achieving flexible lifting of the workpiece. Next, the first drive cylinder assembly is activated, driving the auxiliary clamping mechanism to move the workpiece up and down along the first guide rail to a processing height suitable for the workpiece. Then, the... The second drive cylinder assembly starts, driving the spot welding mechanism to move up and down along the second guide rail to a position close to the workpiece for spot welding. According to the required tilt angle of the workpiece for spot welding, the connecting block is pushed to slide in the arc-shaped slot of the second slider. After the spot welding head assembly is adjusted to the appropriate angle, the connecting block is fixed to the arc-shaped slot by the locking bolt. Finally, the spot welding head assembly performs spot welding. During this process, the position sensor on the side of the second slider monitors the displacement position of the spot welding head assembly in real time and transmits the signal to the second drive cylinder assembly to ensure that the spot welding head assembly is accurately positioned and completes the adaptive positioning spot welding operation of the workpiece.

[0006] The beneficial effects of this utility model are as follows: By integrating an auxiliary clamping mechanism, an auxiliary lifting component, and an adjustable-angle spot welding mechanism, the flexibility and precision of spot welding operations are significantly improved. Specifically, the auxiliary clamping mechanism utilizes a first drive motor to move the clamping hand in opposite directions, allowing for flexible adjustment of the clamping distance to accommodate workpieces of different widths. The silicone material with anti-slip textured pads enhances clamping stability and prevents damage to the workpiece surface. The auxiliary lifting component, through the elastic action of a spring, adaptively conforms to the bottom of the workpiece, achieving flexible lifting and positioning, effectively preventing displacement or deformation of the workpiece during spot welding. The spot welding mechanism, through the design of arc-shaped slots and connecting blocks, allows the spot welding head assembly to slide within a range of 0–60°, thereby achieving adaptive spot welding operations for different tilt angles of the workpiece. A position sensor monitors the displacement of the spot welding head in real time, further improving the positioning and spot welding accuracy. The overall device has a compact structure and flexible operation, not only significantly improving the efficiency and precision of spot welding operations but also significantly enhancing the versatility and adaptability of the device, providing strong support for diversified and personalized production in industrial manufacturing.

[0007] As a further improvement of this utility model, in order to flexibly adjust the clamping distance to adapt to workpieces of different widths, and at the same time provide support for the workpiece during spot welding, thereby improving stability and versatility, the auxiliary clamping mechanism includes a first slider that slides with a first guide rail.

A first drive motor is mounted on the first slider, and the output end of the first drive motor is connected to a clamping hand. The first drive motor drives the clamping hand to move in opposite directions, adjusting the clamping distance to clamp workpieces of different widths. An auxiliary lifting assembly is also mounted on the first slider to lift the workpiece during spot welding.

[0008] As a further improvement of this utility model, in order to adaptively conform to the bottom of the workpiece, avoid the squeezing damage to the workpiece caused by rigid lifting, and effectively prevent the workpiece from shifting or deforming during spot welding, thereby improving the stability of spot welding, the auxiliary lifting component includes a second drive motor fixedly installed on the first slider, and a connecting block is installed and connected to the output end of the second drive motor; a connecting rod is movably embedded on the connecting block, and a lifting block is installed at the top end of the connecting rod; a spring is also sleeved on the outer end of the connecting rod, and the two ends of the spring abut against the end faces of the connecting block and the lifting block respectively; the second drive motor drives the lifting block to move horizontally and adaptively conform to the bottom of the workpiece, thereby achieving flexible lifting and positioning and preventing the workpiece from shifting or deforming during spot welding.

[0009] As a further improvement of this utility model, in order to increase the friction during clamping and prevent the workpiece from slipping, while ensuring the anti-slip effect and avoiding excessive compression of the workpiece, the clamping hands are symmetrically arranged, and an anti-slip soft pad is provided on the inner side of each hand. The anti-slip soft pad is made of silicone material, and its surface is integrally molded with anti-slip texture. The anti-slip soft pad is fixedly attached to the inner clamping surface of the clamping hands by a high-temperature resistant adhesive, and its thickness is 3-5mm.

[0010] As a further improvement of this utility model, in order to achieve adaptive spot welding operations for different tilt angles of the workpiece and improve the adaptability and accuracy of spot welding, the spot welding mechanism includes a second slider that slides with a second guide rail. The second slider has a second mounting hole and is detachably connected to the output end of the second drive cylinder assembly through the second mounting hole. The second slider also has an arc-shaped slot, and a connecting block is movably engaged in the arc-shaped slot. The arc of the arc-shaped slot is 0 to 60°. The connecting block is fixedly connected to the arc-shaped slot by a locking bolt. A spot welding head assembly is also installed on the connecting block. The spot welding head assembly can be slidably adjusted in the arc-shaped slot through the connecting block to adjust the spot welding angle of the spot welding head assembly, thereby achieving adaptive spot welding operations for different tilt angles of the workpiece.

[0011] As a further improvement of this utility model, in order to monitor the displacement position of the spot welding head assembly in real time, ensure the accuracy and stability of the spot welding operation, and improve the spot welding quality, a position sensor is also provided on the side end of the second slider.
