The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the embodiment of the utility model provides a self-locking movable base, which is slidably arranged on a rail 7, and further comprises a machine base frame 2, an air cylinder 1, two locking blocks 5 and two lever mechanisms, wherein the base frame 2 is in a shape of a Chinese character 'ji', and the legs of the Chinese character 'ji' are in sliding contact with the rail 7. The cylinder 1 is fixedly arranged in the middle of the base frame 2, and a piston head of the cylinder 1 is vertical and downward. The cylinder 1 is controlled by electric power, the cylinder 1 is electrically connected with a controller of the external honing machine, and the cylinder is operated corresponding to the production flow of the external honing machine. The locking blocks 5 are respectively arranged on two sides of the base frame 2 close to the rail and are symmetrical relative to the air cylinder 1. The locking block 5 comprises a vertical section and a horizontal section, the vertical section and the horizontal section form an L-shaped structure, the upper section of the vertical section is in sliding connection with the base frame 2, the locking block 5 can only move in the vertical direction, and the horizontal section is arranged below the track. The lever mechanism comprises a power arm, a resistance arm and a fulcrum, wherein the fulcrum is arranged on the base frame 2, the power arm is hinged with the piston head, and the resistance arm is hinged with the vertical section. The lever mechanism is movably connected with the piston head and the locking block 5, so that the piston head and the locking block 5 are driven to move up and down when the power arm and the resistance arm rotate around the pivot.
As shown in fig. 1, 2 and 4, preferably, the power arm and the resistance arm are respectively provided with a bar hole 10, the bar holes 10 are arranged corresponding to the extension lines of the connecting rods 4, and the two ends of the bar holes 10 are provided with arc transitions. In this example, the power arm and the resistance arm form a connecting rod 4, when the piston head of the air cylinder 1 moves up and down, the end part of the connecting rod 4 rotates relative to the connecting point with the base 2, so that the strip-shaped hole 10 enables a gap between the piston head of the air cylinder 1 and the connecting rod 4 when the piston head drives the connecting rod 4 to move up and down, the piston head can displace relative to the connecting rod 4 when the piston head drives the connecting rod 4 to move up and down, and the strip-shaped hole 10 avoids the movement interference of the connecting rod 4, the piston head and the locking block 5. In this example, one end of the connecting rod 4 is hinged to the piston head of the air cylinder 1, the other end of the connecting rod 4 is hinged to the vertical section, the middle part of the connecting rod 4 is connected with the rotating rod of the base 2, the connecting rod 4 is connected with the base 2 at a position close to the locking block 5, a connecting block 3 is arranged at the output end of the air cylinder 1, and the end parts of the two connecting rods 4 are respectively connected with the connecting block 3 in a rotating way. The connecting block 3 and the locking block 5 are respectively provided with a rotating shaft which is matched with the strip-shaped hole 10.
