[0026] The implementation principle of the clamp for machining the cylinder body of an automobile engine is as follows: in use, the engine cylinder body is placed on the placing table 5, the oil cylinder 6 is started through an external hydraulic system, the output end of the oil cylinder 6 jacks up the placing table 5, the engine cylinder body is driven to rise to a specified position, and it is worth noting that the plurality of telescopic columns 4 are elongated when the placing table 5 rises, thereby limiting the rising of the placing table 5 and preventing the placing table 5 from tilting;

[0027] When the engine cylinder is located between the plurality of clamping plates 14, the servo motor 13 is started, the servo motor 13 is connected to an external power supply, and the output shaft of the servo motor 13 drives the bidirectional screw rod 11 to rotate, and the bidirectional screw rod 11 is screwed in the middle inner wall of the two moving blocks 10. Because the middle inner wall of the two moving blocks 10 is provided with threads matched with the outer wall of the bidirectional screw rod 11, the two moving blocks 10 move synchronously, and the plurality of clamping plates 14 clamp one end of the outer wall of the engine cylinder. When clamping, the two anti-skid plates 24 are attached to the end of the cylinder to prevent slipping, and the plurality of clamping plates 14 are inserted into the grooves of the outer wall of the engine cylinder to firmly position the engine.

[0028] Then the oil cylinder 6 drives the placement table 5 to descend and reset, at this time the other end of the cylinder is exposed to a large area with the upper and lower front and rear walls, and the plurality of clamping plates 14 form a hollow to further increase the exposed area of the outer wall of the cylinder, thereby increasing the processing space of the operator, to adapt to various complex processing operations, and the stepping motor 23 can be started.

It is worth noting that because the meshing transmission of the worm gear 20 and the worm 21 has self-locking property, when the stepping motor 23 stops, the worm gear 20 can be locked, thereby stably fixing the engine cylinder at a certain angle to ensure the processing stability.

[0029] In addition, before clamping, the specific position of the plurality of clamping columns 19 can be adjusted according to the groove position of the outer wall of the different engine cylinders. The knob is rotated to drive the threaded rod 17 to rotate, so that the threaded rod 17 is screwed in the inner surface of the movable block 16, thereby driving the movable block 16 to slide in the inner wall of the movable groove 15. The movable block 16 drives the connecting plate 18 to move and stretch, and the connecting plate 18 moves in the buckle of the outer wall of the clamping plate 14 to drive the clamping column 19 at the end to move and adjust the position. It is worth noting that the threads on the outer wall of the threaded rod 17 and the bidirectional screw rod 11 are standard triangular threads with a helix angle of about 30 degrees to realize self-locking function. When the bidirectional screw rod 11 and the threaded rod 17 stop rotating, the position of the moving block 10 and the clamping column 19 can be fixed.
