The invention discloses an automatic rotating clamping mechanism which comprises a base, a feeding mechanism, a moving seat, a rotating positioning mechanism, a portal frame, a downward-pressing oil cylinder and a pressure head. An engine cylinder body is placed at the upper end of the rotating positioning mechanism, and the engine cylinder body is limited by a limiting column arranged on a supporting plate. A positioning oil cylinder drives a guide rod to move upwards along a sliding sleeve through a connecting plate, a positioning pin fixedly connected with the guide rod moves upwards to beinserted into a positioning hole formed in a bottom frame, thus the combined supporting plate is positioned and fixed, and the engine cylinder body is fixed accordingly to prevent the engine cylinderbody from deflecting. Then, the downward-pressing oil cylinder pushes the pressure head to tightly press the engine cylinder body to prevent the engine cylinder body from vibrating in the up-down direction, and then the feeding mechanism works to drive the moving seat to slide along the base, thus the engine cylinder body is driven to slide, and automatic grinding work is facilitated. According tothe automatic rotating clamping mechanism, the structure is simple, the engine cylinder body can rotate by 90 degrees and is positioned, fixed and tightly pressed, meanwhile, the engine cylinder bodycan be automatically fed, grinding is facilitated, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a mechanical device, in particular to an automatic rotating clamping mechanism. Background technique [0002] The cylinder block is one of the important components of the automobile engine. At present, most of the engine cylinder blocks are produced by casting. After pouring, there will be a lot of flashes and pouring risers on the surface of the engine block. These flashes must be removed. Edges and risers, for iron castings, are usually directly knocked off with an oil hammer, while steel castings need to be cut off by gas cutting, and then the remaining flashes and risers on the castings are polished by a casting grinder, making them smooth and beautiful . At present, the engine block grinding process is not highly automated, and manual positioning and adjustment of the casting position are often used, which is not only inefficient, but also has certain safety hazards. In view of the above defects, it is necessary to desig...
