The pressure of the control valve is adjusted to the appropriate range according to the required harness clamping force.

[0135] After the above preparations are completed, you can proceed to the formal operation:

[0136] When the control button is pressed, the control valve 18 is energized and the rod of the hydraulic cylinder 15 pushes the wire harness clamp handle to clamp. When the hydraulic system pressure reaches the set value, the hydraulic control oil circuit pushes the control valve 18 to actuate, causing excess hydraulic oil to return to the hydraulic oil tank 16 instead of entering the hydraulic cylinder 15. At this time, the wire harness clamp will remain clamped, and the clamping force meets the required wire harness compression force. When the control button is released, the control button automatically returns to its original position, the control valve is de-energized, and the rod of the hydraulic cylinder 15 returns to its retracted position, at which point the wire harness clamp returns to its released state.

[0137] In the above technical solution, the present invention provides a clamp auxiliary mechanism and a hydraulic control system thereof, which have the following beneficial effects:

[0138] The mechanism and system of the present invention can be used in conjunction with wire harness clamps of various specifications and models, can ensure the compression quality of the wire harness, avoid manual compression, and greatly reduce the labor intensity of production line employees.
