Description

Technical Field

[0001] The invention relates to the field of tooling fixtures, and in particular to a clamping mechanism for tooling fixtures. Background Art

[0002] The clamping mechanism for tooling and fixtures refers to a mechanical device used to fix the workpiece in the tooling and fixture to ensure that it does not move or loosen during the processing process. These mechanisms clamp and fix the workpiece by applying pressure and friction, thereby ensuring the stability and processing accuracy of the processing.

[0003] For example, the publication number CN215902996U discloses "A clamping mechanism for an electric locomotive bogie frame welding fixture", which includes a clamping body; a cylinder, which is arranged on the top of the clamping body, and the cylinder output end passes through the clamping body and extends to the inside of the clamping body, and one end of the cylinder output end extending to the inside of the clamping body is fixedly connected with a clamping piece; a sliding groove, which is opened in the inside of the clamping piece. By setting the clamping piece, the clamping area can be increased when clamping the metal sheet, and the firmness of the clamping can be improved. By setting a pressing plate in the clamping piece, the clamping area can be expanded, and the excess metal sheet can be clamped to avoid sliding of the metal sheet during welding, thereby reducing the accuracy of the welding position, and further improving the firmness and practicality of the clamping mechanism.

[0039] The present invention provides a clamping mechanism for a fixture through improvement, and its working principle is as follows;

[0040] First, before use, place the object to be compressed under the rotating head 21 and wait for compression;

[0041] Second, when in use, the electric push rod 46 is started, so that the electric push rod 46 pushes the fixed block 47 to move, and when the fixed block 47 moves, it drives the support rod 48 to move, and when the support rod 48 moves, it drives the rotating head 21, and when the rotating head 21 moves, it drives the pressing block 22 to move, and the fixed block 47 drives the fixed plate 49 to move at the same time, and when the fixed plate 49 moves, it drives the movable block 55 to move through the limit rod 52, and when the movable block 55 moves, it drives the distance sensor 57 to move through the adjustment rod 56, and the distance sensor 57 detects the position of the object;

[0042] Third, the second motor 4103 drives the worm 4102 to rotate, and when the worm 4102 rotates, it drives the worm wheel 4104 to rotate, and when the worm wheel 4104 rotates, it drives the rotating rod 43 to rotate, and when the rotating rod 43 rotates, it drives the second electric push rod 46 to rotate, and when the second electric push rod 46 rotates, it drives the fixed plate 49 to rotate through the fixed block 47, and when the fixed plate 49 rotates, it drives the distance sensor 57, and the distance sensor 57 is used to detect the object;

[0043] Fourth, when an object is detected below, the motor 35 drives the screw 33 to move, and when the screw 33 rotates, it drives the movable sleeve 36 to move, and when the movable sleeve 36 moves, it drives the main body 1 to move, and when the main body 1 moves, it drives the rotating head 21 to move through the connecting block 42;

[0044] Fifth, when the rotating head 21 moves, it drives the movable rod 51 to move. When the movable rod 51 moves downward, it squeezes the movable block 55, so that the movable block 55 moves leftward along the limit rod 52. When the movable block 55 moves, it squeezes the spring 54. When the movable block 55 moves, it drives the adjusting rod 56 to move. When the adjusting rod 56 moves, it drives the distance sensor 57 to move, so that the distance sensor 57 moves out of the bottom end of the pressing block 22.

[0045] Sixth, when the pressing block 22 reaches the designated location, the electric push rod 23 is started, so that the electric push rod 23 pushes the pressing block 22 to squeeze the object. After the squeezing is completed, the electric push rod 23 controls the pressing block 22 to return to the original position, and the motor 35 rotates to control the main body 1 to rise, thereby driving the rotating head 21 to rise;

[0046] Seventh, when the rotating head 21 rises, the rotating head 21 drives the movable rod 51 to move. When the movable rod 51 moves out of the top of the movable block 55, the spring 54 loses its force and releases elastic potential energy to push the movable block 55 to move. When the movable block 55 moves, it drives the adjusting rod 56 to move. When the adjusting rod 56 moves, it drives the distance measuring sensor 57 to move, so that the distance measuring sensor 57 moves to the bottom end of the clamping block 22, waiting for the next use.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
