Detailed ways

A kind of engine block turning mechanism of the present utility model is described in detail below in conjunction with accompanying drawing.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, an engine block turning mechanism 4 includes a frame 1, a jacking cylinder 7 is arranged at the bottom of the frame 1, and a deceleration device is arranged on the frame 1 next to the jacking cylinder 7. The motor 2, the frame 1 on one side of the jacking cylinder 7 is provided with a guide rod 6, the top of the cylinder rod of the jacking cylinder 7 is connected with a push plate 5 with several grooves on both sides, and the center of the top of the frame 1 is provided with a turning mechanism 4 , the groove at the push plate 5 in the middle of the frame 1 is provided with a conveying line 3 composed of several conveying rollers, one end of the conveying roller is installed on the side of the conveying line 3 through a bearing, and the gear 4-7 inside the conveying roller passes through the output of the chain and the motor The shafts are connected; the turning mechanism 4 includes a connecting rod 4-2, a clamping cylinder 4-3 is arranged under the middle part of the connecting rod 4-2, and an arm 4-1 and an arm 4 are respectively arranged on both sides of the bottom of the connecting rod 4-2. The inner side of -1 is provided with a rotary cylinder 4-5, the end of the cylinder rod of the rotary cylinder 4-5 is connected with a rack 4-6, the rack 4-6 cooperates with the gear 4-7, and the gear 4-7 is connected to the arm 4 through the connecting shaft The fingers 4-4 on the outside of -1 are connected; the limit pin 4-9 for limiting the finger 4-4 is set between the arm 4-1 and the finger 4-4, and a proximity switch is set next to the limit pin 4-9 4-8; the conveying rollers on the conveying line 3 are two rows, and one row of conveying rollers is connected to the reduction motor 2 through a chain; the end of the push plate 5 is provided with a stop block for blocking the engine block; The side of the frame 1 is provided with a controller, and the controller is used to control the operation of the reduction motor 2, the rotating cylinder 4-5 and the clamping cylinder 4-3.
