After the control unit 106 performs image recognition on the bolt position, the control unit 106 controls the operation of the servo motor C2010 to drive the vertical ball nut seat 2052 in the vertical slide 2 to translate the vertical position, so that the vertical height of the rotating seat 2061 can be aligned with the wheel. The control unit 106 controls the operation of the electric reciprocating cylinder 2062, so that the telescopic part can reciprocate and drive the transmission rack 2063 to reciprocate, and can drive the meshing driven gear 2072 to rotate, so that the jack rocker position can be rotated, so that the telescopic part of the screw jack 207 can be contracted inward, and the tooth clamp 2071 at the end of the telescopic part can clamp and fix the inner wheel. The control unit 106 controls the operation of the electric push rod 208, so that when the servo motor B2086 is translated to the left, the nut sleeve 2087 is elastically reset by the spring, and when the inner profile of the nut sleeve 2087 is aligned with the outer side of the nut during the rotation of the nut sleeve 2087, the spring is expanded, The nut sleeve 2087 is driven to translate to the right side and sleeved to the outside of the nut, so that the nut can be automatically sleeved. The servo motor B2086 is controlled by the control unit 106 to operate, so that the nut sleeve 2087 drives the nut of the hub bolt to be automatically removed. The servo motor A2081 is rotated to drive the nut sleeve 2087 to rotate to the next group of bolts. The reciprocating screw 2083, the servo motor A2081 and the electric push rod 208 are controlled by the control unit 106 to cooperate in operation, so that the nut sleeve 2087 can automatically dock and remove the nut of the hub bolt in turn. After the tire is driven to translate out of the axle by controlling the vertical slide 2, the wheel can be automatically disassembled. After the vertical slide 2 is translated to the left side of the receiving groove 104,After the engineering vehicle wheel to be replaced is hoisted to the inner side of the two sets of hinged guard plates 107 by a crane, the two sets of receiving hydraulic cylinders 1021 are controlled by the control unit 106 to operate, so that the telescopic parts can support the hinged guard plates 107, and the two sets of hinged guard plates 107 can clamp and fix the wheels. After the gear clamp 2071 is tilted and rotated forty-five degrees by controlling the operation of the primary motor 206, the gear clamp 2071 is moved to the gap between the wheel and the hinged guard plate 107 by controlling the vertical slide 2 to move to the right, and then the screw jack 207 is controlled to operate so that the gear clamp 2071 is fixed to the wheel. After clamping, the longitudinal screw rod 1081 can be controlled to rotate so that the vertical slide 2 drives the wheel to move to the right to the wheel hub. When the electric push rod 208 drives the nut sleeve 2087 to move to the left, the nut is inserted into the nut sleeve 2087. The electric push rod 208 drives the nut sleeve 2087 to move horizontally. When the nut sleeve 2087 drives the nut to move to the left wheel hub direction, the servo motor B2086 is operated, so that the nut sleeve 2087 drives the nut to rotate, and the nut can be automatically tightened, which is convenient for quick automatic installation of the wheel.

[0044] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0045] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
