Problems solved by technology
[0003] 1. The accuracy of scoring is not high
First of all, since the device is driven by T-shaped thread, in order to ensure that the associated parts can move flexibly with each other, the matching gap between them is very large; secondly, the device is divided by the positioning reference block in the middle, and the reference block is very easy. Wear and tear, resulting in the deviation of the centering of the workpiece, making the parting inaccurate
[0004] 2. Large space is required for installation
Since the device is manually twisted, for the convenience of operation, the centering device is extended outside the parts, resulting in no place for other devices to be placed, and a large installation space
[0005] 3. Inconvenient operation and high labor intensity

A wedge-lever automatic edge finding device is used for automatic edge finding of symmetric parts. A guide sleeve is fixed in a positioning hole of a bottom plate. A base is positioned through the guide sleeve and installed below the bottom plate. A cylinder is fixed on the base. A cylinder push bar is mounted on a wedge of a right mechanism. The right mechanism is connected with a wedge of a left mechanism through a connecting bar. Support bars are perpendicularly disposed in the guide sleeve. A dust ring is mounted between the support bars and the guide sleeve. T-blocks at the lower ends of the support bars are disposed in T-grooves of the wedges. The other end of each support bar is connected with an edge finding block through a connector. The edge finding block is connected to a lever support through a pin. The lever support is fixed on the bottom plate. The T-grooves in the wedges are used to drive the pin on the edge finding block for transmission through the support bars; thrust of the cylinder is evenly distributed to two edge finding heads through the wedges and a lever device; accordingly, automatic and accurate edge finding is achieved. The wedge-lever automatic edge finding device has the advantages that edge finding is high in precision, performance is stable, operation is simple and convenient and the device is resistant to interference and high in universality.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a wedge lever type automatic centering device for automatic centering of symmetrical parts. Background technique [0002] At present, for the processing of symmetrical parts, how to carry out high-precision centering of parts in a small space is a difficult problem in the machinery industry. The current method is to drive two screw sleeves to move simultaneously through a T-shaped screw rod to carry out centering, but this device has the following disadvantages. [0003] 1. The accuracy of scoring is not high. First of all, since the device is driven by T-shaped thread, in order to ensure that the associated parts can move flexibly with each other, the matching gap between them is very large; secondly, the device is divided by the positioning reference block in the middle, and the reference block is very easy. Abrasion causes the workpiece to be centered and d...
