Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment: As shown in Figures 1-3, in this embodiment, a steering knuckle hydraulic automatic clamping mechanism is provided, including a base 1, a universal head 2 is arranged above the base, and the base 1 A push rod 3 is vertically penetrated inside, the upper end of the push rod 1 is provided with an arc-shaped groove 31, and the lower part of the universal head 2 is provided with an arc-shaped protrusion 21 matched with the arc-shaped groove. The head and the push rod are connected by a number of fasteners 4, there is a swing space 5 between the universal head and the push rod, a pair of clamping jaws 6 are hinged on both sides of the universal head, and the middle part of each clamping jaw is A link plate 7 is hinged, and the other end of the link plate is hinged with the base 1 .

In this embodiment, an oil cylinder 8 for pushing the push rod to move up and down is disposed below the base 1 , and the output end of the oil cylinder is connected to the push rod.

In this embodiment, an upper base 9 is arranged above the base, a pair of uprights 10 are symmetrically arranged on both sides above the upper base 9, and both ends of the hinge plate 7 are hinged on the middle of the clamping jaw 6 and the uprights 10 respectively, and are fastened. The parts pass through the universal head, the upper base and the push rod in turn and connect the universal head, the upper base and the push rod.

In this embodiment, a linking plate 7 is hinged on both sides of each upright column, and the ends of the two linking plates are also hinged on both sides of the middle of the clamping jaw respectively, so as to increase the stability.

In this embodiment, the fastener is a bolt, the bolt 11 includes a nut 110 and a screw rod 120, and an adjustment distance 130 is provided between the lower end surface of the nut and the universal head.

In this embodiment, when the workpiece to be clamped has a rough surface, due to the different clamping positions of the clamping jaws, it is possible that one of the clamping jaws clamps the convex surface of the workpiece surface, and the other clamping jaw clamps the convex surface of the workpiece surface. The concave surface causes one of the jaws to clamp the convex surface first, but the other jaw cannot clamp the concave surface. When the convex surface is clamped, and the other clamping jaw has not clamped the concave surface, the oil cylinder continues to push the push rod to move, and there is a swing space between the universal head and the push rod, so that the universal head can be deflected by force and cooperate with the lower end face of the nut. The adjustment distance set between the universal head and the universal head causes the universal head to swing, so that the other clamping jaw can further clamp the corresponding concave surface of the workpiece.

In this embodiment, the clamping jaws 6 are arc-shaped.

In this embodiment, when working, place the workpiece, the oil cylinder 8 drives the push rod 3 to move upward, pushes the universal head and the universal head to move upward, drives the link plate and the clamping jaw 6 to swing, so that the clamping jaw clamps the workpiece , when the workpiece we clamped is a rough surface, one of the clamping jaws clamps the workpiece, while the other clamping jaw has not clamped the workpiece due to the uneven surface of the workpiece, the cylinder continues to move to push the push rod, and the arc at the upper end of the push rod The force of the groove is matched with the arc-shaped protrusion below the universal head, so that the universal head 2 swings, so that the other clamping jaw can also clamp the workpiece surface, so as to complete the clamping work of the workpiece with rough surface . The utility model has ingenious structure, reasonable design and convenient use.
