Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a multi-station pneumatic clamp device. Background Art
[0002] Pneumatic clamps refer to devices used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection. The existing pneumatic clamps can only perform single clamping in actual use, and can be installed in a matching manner with the workpiece through its specially set positioning rod, thereby improving the clamping fixation. However, with long-term use, the clamp itself will also wear, so it usually causes the workpiece to deviate during welding, resulting in the weld being unable to dock, making the welded workpiece unstable. The existing devices still have some defects; for example;
[0003] For example, a multi-station pneumatic clamp device with the publication number CN219359278U, when using its technology, first manually twist the threaded rod to rotate, and the rotation of the threaded rod drives the moving frame to move, and finally the second top plate is moved to the edge of the workpiece and stops, and then the workpiece is installed on the top of the base through the limit rod. During the installation process, the workpiece is slightly pushed forward to slide down, and then the cylinder is started to drive the pressure rod to descend to press the edge side of the workpiece to fix it, and then the electric telescopic rod is started to push the lifting plate to push up, and the lifting of the lifting plate will drive the second top plate and the first top plate to rise. If the second top plate does not touch the workpiece during the rising process, the second top plate will not descend. If the position of the workpiece is offset, it will block the second top plate, thereby pushing the second slide bar down and pressing the second button to light up the warning light, which reminds the staff that the workpiece is offset. During this process, the first top plate directly contacts and presses the bottom of the workpiece. If the workpiece is clamped stably, the lifting plate rises to the limit position, the first slide bar descends, and the first button is pressed to light up the prompt light.
[0004] The above device has some problems. When the device is used, the hand twists the threaded rod to rotate, and the rotation of the threaded rod drives the moving frame to move, which is less effective. The device cannot be adjusted during use, and the use effect is not good.
