The specific workflow of the squat debugging platform provided by the invention is as follows:
in an initial state, a piston rod of the double-acting hydraulic cylinder 6 is in a contracted state and abuts against a gun tail 202 of the gun barrel 2, a blocking head 132 of the sear 13 abuts against a locking support arm 141 of the rotary block 14 and protrudes outwards of the mounting frame 12, when the double-acting hydraulic cylinder 6 receives a simulated squat instruction, the pump station injects liquid into the double-acting hydraulic cylinder 6 so as to drive a barrel 201 of the gun barrel 2 to squat, and during squat, a second contact surface 112 of a bevel iron 11 fixed on the barrel 201 is firstly contacted with the locking support arm 141 of the rotary block 14, and then the rotary block 14 and the sear 13 are pressed into the mounting frame 12 in sequence; when the inclined stop iron 11 passes through the stop iron 13, the rotation stop block 14 and the stop iron 13 spring up and are exposed out of the mounting frame 12 under the action of a return spring; when the pipe body 201 is squat to a designated position (namely when the squat length reaches 530 mm-600 mm), after squat is finished, the corresponding electromagnetic valve is controlled to reversely inject liquid into the double-acting hydraulic cylinder 6, so that the double-acting hydraulic cylinder 6 returns to the initial position, and the squat thrust is quickly relieved; then stopping the injection of the liquid into the double-acting hydraulic cylinder 6, pushing the gun tail 202 to perform the double-acting operation through the double-acting mechanism, and at the moment, the sear 13 abuts against the inclined plane sear 11, so that the tube body 201 of the gun tube 2 is stopped.
When the unlocking hydraulic cylinder 20 is connected to a return instruction, the piston rod of the unlocking hydraulic cylinder 20 is controlled to extend through the pump station, the unlocking sliding block 18 is pushed to slide forwards through the push rod 19, at this time, the second return spring 17 is compressed, the rotation stop block 14 can rotate clockwise under the pushing of the unlocking sliding block 18, the tightening sliding block 16 can slide forwards along with the pushing of the unlocking sliding block 18 and compress the first return spring 15, meanwhile, along with the clockwise rotation of the rotation stop block 14, the locking support arm 141 of the rotation stop block 14 can be separated from the blocking head 132 of the blocking iron 13 and enter the groove 181 of the blocking iron 13, the blocking iron 13 rotates anticlockwise, the blocking surface 131 and the blocking head 132 are guaranteed to retract into the mounting frame 12, so that the pipe body 201 is released, the pipe body 201 continues to return under the acting force of the return hydraulic cylinder 7 until the tail 202 of the gun barrel 2 is abutted back to the piston rod 202 of the double-acting hydraulic cylinder 6 again, and thus a manual return and sitting cycle is completed.
The above embodiments are only for illustrating the present invention, and are not limiting of the present invention. While the invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, and substitutions can be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
