[0015] The present utility model will be described in detail below in conjunction with the drawings and specific implementation modes.

[0016] As Figure 1 shown, the present utility model provides a flexible safety clamping device for flipping a diesel engine, which includes a cross beam 4. A slide rail is provided on the bottom surface of the cross beam 4. A front-end face clamping arm 5 and a rear-end face clamping arm 8 are slidably connected to the slide rail. An air-liquid locking unit 6 is connected to the side of the front-end face clamping arm 5 close to the cross beam 4. The air-liquid locking unit 6 is also fixedly connected to the cross beam 4. The front-end face clamping arm 5 and the rear-end face clamping arm 8 are respectively connected with corresponding power units.

[0017] The air-liquid locking unit 6 includes a first fixing seat 601. The first fixing seat 601 is fixedly connected to the side of the front-end face clamping arm 5 close to the cross beam 4. A clamping rod 605 is fixedly connected to the first fixing seat 601. The first fixing seat 601 and the clamping rod 605 move along with the front-end face clamping arm 5.

[0018] The air-liquid locking unit 6 further includes a second fixing seat 604. The cross-section of the second fixing seat 604 is L-shaped. A first opening is formed on the second fixing seat 604, and the second fixing seat 604 is fixedly connected to the bottom of the cross beam 4. A hydraulic locking cylinder 603 is fixedly connected inside the first opening. The clamping rod 605 passes through the hydraulic locking cylinder 603.

[0019] The air-liquid locking unit 6 further includes a third fixing seat 606. The cross-section of the third fixing seat 606 is n-shaped, and the third fixing seat 606 is fixedly connected to the second fixing seat 604. An air cylinder lock 602 is fixedly connected inside the third fixing seat 606. The part of the clamping rod 605 that passes out of the hydraulic locking cylinder 603 penetrates into the air cylinder lock 602. A second opening is formed in the middle of the third fixing seat 606, and the clamping rod 605 passes out through the second opening. A limiting block 607 is fixedly connected to one end of the clamping rod 605 that passes out of the second opening.

[0020] The front-end face clamping arm 5 is connected with a front-end face clamping jaw 3, and the rear-end face clamping arm 8 is connected with a rear-end face clamping jaw 2.

[0021] A pneumatic oil pump unit 1 is fixedly connected to the cross beam 4. The pneumatic oil pump unit 1 is connected to the hydraulic locking cylinder 603 through a hydraulic oil pipeline to provide power for the hydraulic locking cylinder 603. The air cylinder lock 602 is connected to an air pump through an air pipeline.

[0022] The laser displacement sensor 7 installed on the cross beam is used to obtain the accurate position of the clamping arm. During the process of turning over the diesel engine, the change value of the laser displacement sensor 7 is monitored to judge whether the clamping of the clamping arm is reliable.

[0023] The working principle of the flexible safety clamping device for turning over a diesel engine provided by the present utility model is as follows:

[0024] After the engine reaches the work station, start the relevant power unit to drive the front-end face clamping arm 5 and the rear-end face clamping arm 8 to extend or contract, so that the front-end face clamping jaw 3 and the rear-end face clamping jaw 2 grip the engine; when the end face clamping arm 5 slides, it will drive the first fixed seat 601 and the clamping rod 605 to move; the second fixed seat 604 will not move because it is fixedly connected to the cross beam 4. Similarly, the hydraulic locking cylinder 603 and the cylinder lock 602 are also relatively stationary relative to the cross beam 4, and the clamping rod 605 passing through the hydraulic locking cylinder 603 and the cylinder lock 602 slides; the laser displacement sensor 7 collects the position of the clamping arm in real time during the clamping process to detect whether the clamping position is reached. If it reaches, control the solenoid valve to suck in, start the pneumatic oil pump unit 1, control the hydraulic locking cylinder 603 to hold the clamping rod 605 tightly and synchronously close the cylinder lock 602, and the equipment starts to perform the flipping operation. During the flipping process, monitor the laser displacement sensor 7 and the pressure of the hydraulic circuit to ensure the safe and reliable operation of the clamping and holding device; when the power is interrupted, the pneumatic oil pump unit 1 cannot provide power, the hydraulic locking cylinder 603 fails to lock the clamping rod 605, and the cylinder lock 602 fails to lock the clamping rod 605. Through the above settings, when the power is interrupted, the device can achieve the emergency stop function and achieve the purpose of safe production.
