PREFERRED EMBODIMENT

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-5 As shown, this utility model provides a welding clamping and conveying mechanism for automotive side panels, including a base plate 1. Support plates 101 are fixedly connected to both sides of the top of the base plate 1. An assembly plate 102 is fixedly connected to the top of the support plates 101. A welding table 2 is provided on the top of the assembly plate 102. A control component 3 is provided at the bottom of the welding table 2. The control component 3 includes three telescopic cylinders 301. The tails of the three telescopic cylinders 301 are respectively hinged to the two support plates 101 and the surface of the base plate 1. Ball seats 302 are fixedly connected to the output ends of the three telescopic cylinders 301. 1. The ball seat 302 is perpendicularly distributed to each other. The ball seat 302 has a first sliding ball 303 inside. The first sliding ball 303 is slidably connected to the inner wall of the ball seat 302. The top of the first sliding ball seat is fixedly connected to a connecting roller 304. The top of the connecting roller 304 is fixedly connected to a connecting ring 305. The connecting ring 305 has a second sliding ball 306 inside. The second sliding ball 306 is slidably connected to the inner wall of the connecting ring 305. The top of the second sliding ball 306 is fixedly connected to a support roller 307. The welding table 2 is installed on the top of the support roller 307. Three telescopic cylinders 301 distributed perpendicularly to each other serve as power sources. When a telescopic cylinder 301 extends or retracts, its output end is connected to the welding table 2 via a ball seat 302, a first sliding ball 303, a connecting roller 304, a connecting ring 305, a second sliding ball 306, and a support roller 307. The connecting roller 304 slides within the cross-shaped connecting window 314 of the arc-shaped shell 313, which serves as a fixed fulcrum. Therefore, the extension or retraction of the telescopic cylinder 301 is converted into movement of the welding table 2 in the corresponding direction (front-back or left-right). For example, when a telescopic cylinder 301 parallel to the front-back direction extends or retracts, it pushes the connecting roller 304 to slide in the front and back portions of the cross-shaped connecting window 314, thereby causing the welding table 2 to move back and forth. Similarly, when a telescopic cylinder 301 parallel to the left-right direction moves, it causes the welding table 2 to move left and right.

[0026] Further, the connecting frame 308 is sleeved around the connecting ring 305 and is fixedly connected with the outer surface of the connecting ring 305, the bottom of the connecting frame 308 is sleeved with the telescopic spring 309, the bottom of the telescopic spring 309 is provided with the fixed seat 310, the top of the fixed seat 310 is provided with the connecting slot 311, one end of the telescopic spring 309 is fixedly connected with the bottom of the inner cavity of the connecting frame 308, the other end of the telescopic spring 309 is fixedly connected with the bottom of the inner cavity of the connecting slot 311, the bottom of the fixed seat 310 is fixedly connected with the arc-shaped seat 312, the bottom of the arc-shaped seat 312 is sleeved with the arc-shaped shell 313, the arc-shaped seat 312 is slidably connected with the inner wall of the arc-shaped shell 313, the surface of the arc-shaped shell 313 is provided with the through cross-shaped communication window 314, the connecting roller 304 is slidably connected with the inner wall of the cross-shaped communication window 314, and the outer surface of the arc-shaped shell 313 is fixedly connected with the assembly plate 102. When the bottom telescopic cylinder 301 is stretched, the ball seat 302, the connecting roller 304 and other components are pushed to move upward, and then the welding table 2 is moved upward. In this process, the telescopic spring 309 is stretched. When the bottom telescopic cylinder 301 is contracted, the welding table 2 moves downward under the action of the restoring force of the telescopic spring 309, the telescopic spring 309 returns to the original length or approaches the original length, so that the upward and downward movement of the welding table 2 is realized.

[0027] The automobile side wall is fixed on the welding table 2 by the clamping piece, and the welding table 2 can move in six degrees of freedom in all directions. The multi-dimensional adjustment capability can accurately align the welding position of the automobile side wall, adapt to automobile side wall workpieces of different shapes, sizes and welding requirements, improve the accuracy and flexibility of welding, adopt the connection mode of the ball seat 302 and the sliding ball, and cooperate the connecting ring 305 and the second sliding ball 306, which can effectively disperse the force and reduce the friction and wear between the components, improve the overall stability and service life of the mechanism. The spherical contact of the ball seat 302 and the sliding ball can make the connecting roller 304 bear force uniformly in different directions, reducing stress concentration. The telescopic spring 309 not only plays a buffering role in the upward and downward movement of the welding table 2, avoiding the impact on the welding table 2 and the workpiece caused by the sudden action of the telescopic cylinder 301, but also provides a reset force when the welding table 2 moves downward, so that the welding table 2 can smoothly return to the initial or set position, which helps to maintain the stability and repeatability of the welding process.

[0028] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
