Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the embodiment of the utility model provides a milling plane processing positioning fixture, including anchor clamps base 1, be provided with multiunit positioning baffle 2 in one side of anchor clamps base 1, the opposite side is provided with multiunit location glass pearl 3, positioning baffle 2's bottom and anchor clamps base 1 fixed connection, location glass pearl 3 sets up on location glass pearl support 4, location glass pearl support 4's bottom also with anchor clamps base 1 fixed connection. The positioning glass bead 3 is composed of steel beads, springs, a shell and the like, has elastic clamping and buffering effects, the positioning baffle 2 is matched with the positioning glass bead 3, and the positioning glass bead 3 pushes one end face of the workpiece 5 to be tightly attached to the positioning baffle 2.
Meanwhile, the clamp base 1 is also provided with a pressing plate mechanism which comprises a corner cylinder 6 and a pressing plate 7 arranged at the end part of a piston rod of the corner cylinder 6, the pressing plate 7 is positioned in the middle of the workpiece 5, the pressing plate 7 is in a transverse state when the workpiece 5 is not clamped, and when the workpiece 5 is arranged on the clamp base 1 and is elastically clamped by the positioning glass beads 3 and the positioning baffle 2, the corner cylinder 6 drives the pressing plate 7 to rotate firstly and then linearly press downwards to further clamp the workpiece 5.
In order to ensure that the workpieces 5 clamped by the clamp are all kept horizontal and are positioned on the same horizontal plane, and one-time feeding and plane milling of a milling cutter are facilitated, the two sides of the clamp base 1 are provided with parallel and level cushion blocks 8, the two ends of each workpiece are respectively placed on the cushion blocks 8 on the two sides when the workpieces are clamped, all the workpieces 5 are kept on the same horizontal plane, and the milling cutter is used for milling the upper surfaces of the workpieces.
And, the both sides of anchor clamps base 1 still are provided with a plurality of navigation keys 9, and the right-angle limit is formed in the combination of positioning baffle 2 and the navigation key 9 that correspond, and the right-angle limit is formed in the same combination of location glass pearl support 4 and the navigation key 9 that corresponds. When a workpiece 5 is clamped and clamped by the clamp, two ends of the workpiece 5 are respectively contacted with the positioning glass beads 3 and the positioning baffle 2, then the workpiece 5 is moved to enable the side walls close to the two ends to be tightly attached to the side walls of the positioning keys 9, so that the position of the workpiece 5 on the horizontal plane is positioned, and the workpiece is pressed by the pressing plate 7 to realize complete positioning.
