Automatic positioning clamping mechanism for feeding and discharging materials in bell-shaped shell defect-detection/cleaning integrated machine

Abstract

The invention relates to an automatic positioning clamping mechanism used for feeding and discharging materials in a bell-shaped shell defect-detection / cleaning integrated machine. The mechanism is characterized by fixing a pair of cylinder connecting plates on the top surface of an installing substrate; two pairs of, in other words, four sliding blocks in all, are configured on a straight line guide track at the lower part in front of the installing substrate; a clamping jaw is L-shaped; V-shaped chucks are arranged on the internal side surface at the front parts of a pair of clamping jaw horizontal arms respectively; four clamping jaws are fixed on the four sliding blocks through a perpendicular arm respectively; a cylinder is fixed on the cylinder connecting plate; a movable joint is fixed on a stretching end of a piston rod of the cylinder; the movable joint is U-shaped and the opening thereof faces downwards; each pair of connecting rods are matched in a U-shaped slot of the movable joint rotationally through a hinge pin; and the other ends of each pair of connecting rods are matched on a pair of clamping jaw perpendicular arms rotationally through screws. According to the mechanism, working pieces of different models can be positioned and clamped accurately without adjustment; the adjusting working quantity of the machine can be reduced greatly; the operation is sensitive and reliable; and the production efficiency can be improved greatly.

Description

technical field [0001] The invention relates to a non-destructive testing machine, in particular to an automatic positioning and clamping mechanism in the loading and unloading of a bell-shaped shell magnetic particle flaw detection and cleaning integrated machine. Background technique [0002] In the prior art, there are two kinds of positioning and clamping mechanisms in the loading and unloading of the all-in-one machine: the first is to drive the double-sector teeth through the cylinder to push the double-sided rack to achieve the purpose of clamping. This method is not only complicated in structure, but also can only A workpiece with a fixed size can achieve accurate positioning. When the size of different types of workpieces changes, because the clamping jaws on the sector move in a circular motion, the center cannot be positioned; the second is that the two clamping jaws are driven by double cylinders. This method In theory, only by adjusting the pressure balance of t...

[0002] In the prior art, there are two kinds of positioning and clamping mechanisms in the loading and unloading of the all-in-one machine: the first one is to drive the double-sided tooth rack through the cylinder to drive the double-sector teeth to achieve the purpose of clamping. This method is not only complicated in structure, but also only suitable for One type of workpiece with a fixed size achieves accurate positioning. When the size of different types of workpieces changes, the center cannot be positioned because the jaws on the sector are in circular motion. The second type is that the two jaws are driven by double cylinders. Theoretically, the synchronization of the two jaws can be realized only by adjusting the pressure balance of the cylinders on both sides. Rarely used in actual production
