Fast adjustment trifurcate synchronous telescopic rotation clamp

Abstract

The invention relates to the field of clamp devices, in particular to a fast adjustment trifurcate synchronous telescopic rotation clamp. The fast adjustment trifurcate synchronous telescopic rotationclamp comprises fast sliding groove supporting arms, a rotary disc, a directional triangular disc and a rotating shaft rod. A shaft hole A is formed in the center of the directional triangular disc.The rotating shaft rod is inserted in the shaft hole A. A rotating shaft rod ejecting head is arranged on the top of the rotating shaft rod. The rotating shaft rod ejecting head is inserted in a concave hole formed in the center of the axis of the rotary disc. The concave hole has a large upper portion and a small lower portion, and the rotating shaft rod ejecting head is sleeved with a fast clamping sleeve and is fixed in the concave hole after being inserted in the concave hole so that the rotating shaft rod can drive the rotary disc to rotate rotationally. Guide positioning shoes are arranged at the positions of the three corners of the directional triangular disc. Each fast sliding groove supporting arm comprises a bottom connector at the bottom of the fast sliding groove supporting arm and a groove rod which integrally extends from the connector and is provided with a bottom sliding groove, wherein multiple adjustable insertion holes are formed in an ejecting piece of the groove rod at equal intervals. The guiding positioning shoes of the triangular disc are clamped in the bottom sliding grooves and slide in the bottom sliding grooves. The concave hole is matched with the rotary disc.

Description

technical field

[0001] The invention relates to the field of clamp devices, in particular to a fast-adjusting three-prong synchronous telescopic rotary clamp. Background technique

[0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection, also known as fixture. In a broad sense, in any process in the process, the device used to quickly, conveniently and safely install the workpiece can be called a fixture; the fixture is usually composed of positioning elements (determining the correct position of the workpiece in the fixture), clamping Device, tool setting guide element (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing device (to enable the workpiece to complete the processing of several stations in one installation, there are rotary indexing device and linear moving indexing T...
