[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1-3The embodiment of the utility model discloses: a clamping device for a moving vehicle workpiece, comprising a frame 1 and a sliding electric cylinder 6, wherein a fixed plate is symmetrically provided at one end of the frame 1, and two limit rods 2 that are against the workpiece are provided on the fixed plate, and a clamping rod 3 for clamping the workpiece is symmetrically provided at the other end of the frame 1, and a sliding channel is opened on the frame 1, and the sliding electric cylinder 6 is arranged in the frame 1, and a sliding plate 31 is provided on the sliding electric cylinder 6 to match the number of the clamping rods 3, and the sliding plate 31 is connected to the clamping rod 3, and the frame 1 is also provided with a stabilizing device for firmly clamping the workpiece.

[0021] Specifically, the stabilizing device includes four lifting plates 5, which are evenly arranged on the frame 1 and located on both sides of the clamping rod 3. Two suction cups 4 capable of sucking workpieces are symmetrically arranged on the lifting plates 5. The frame 1 is provided with a first lifting cylinder 7 for driving the lifting plates 5 to rise and fall. The first lifting cylinder 7 is arranged in the frame 1, and the extending rod of the first lifting cylinder 7 is connected to the lifting plates 5.

[0022] When in use, the frame 1 is connected to the external robotic arm. When the workpiece needs to be clamped, the sliding electric cylinder 6 works to drive the clamping rod 3 to slide, the clamping rod 3 resists the workpiece, and pushes the rear end to resist the limit rod 2, so that the front and rear ends of the workpiece are positioned, and then the first lifting cylinder 7 works to drive the suction cup 4 downward, the suction cup 4 contacts the workpiece, and then the suction cup 4 works to suck the workpiece, thereby realizing secondary clamping of the workpiece, avoiding the heavy workpiece from falling off easily during clamping, which is beneficial to safe production.

[0023] In order to be able to clamp the controlled workpiece so that the clamping claw can clamp different workpieces, it also includes a first clamping block 21, a second clamping block 22, and two connecting plates 10. The first clamping block 21 and the second clamping block 22 are respectively arranged on two limit rods 2. The first clamping block 21 is provided with a V-shaped clamping groove, and the second clamping block 22 is provided with a V-shaped boss that can penetrate into the clamping groove. The two connecting plates 10 are symmetrically arranged on the fixed plate, and the limit rod 2 is hinged between the two connecting plates 10. The limit rod 2 is inclined. A swing rod 23 is obliquely arranged and is located between the connecting plates 10. An opening and closing channel is provided on the swing rod 23. A linkage plate is provided inside the frame 1. A connecting block 8 is provided on the linkage plate. A swing channel is provided on the connecting block 8. A swing rod 23 is provided in the swing channel. The swing rod 23 is located in the opening and closing channel. A second lifting cylinder 9 for driving the connecting plate 10 to rise and fall is provided inside the frame 1. The second lifting cylinder 9 is arranged on the frame 1. The extension rod of the second lifting cylinder 9 is connected to the linkage plate. When the workpiece is to be clamped, the second lifting cylinder 9 works to push the linkage plate downward, and the linkage plate drives the connecting block 8 downward. When the linkage plate moves downward, the swing rod 23 slides downward in the opening and closing channel, thereby opening the limit rod 2. When the limit rod 2 is located at the position of the controlled workpiece, the second lifting cylinder 9 returns to its position, thereby driving the limit rod 2 to return to its position. At this time, the engaging boss on the limit rod 2 is engaged in the engaging groove, and the controlled workpiece is clamped in the V-shaped groove, thereby clamping the controlled workpiece.
