Autotracking centring clamping device for numerically controlled grinder

Abstract

The invention discloses an automatic follow centering and clamping device for a numerical control grinder. A middle clamping rod (5) is sleeved in a sliding way on a supporting body (12) which is provided with a driving mechanism which drives the middling clamping rod (5) to reciprocatingly move axially. An upper lever clamping arm (4) and a lower lever clamping arm (15) are hinged on the supporting body (12) with the middle clamping rod (5) axis of symmetry. The clamping ends of the upper lever clamping arm (4) and the lower lever clamping arm (15) are corresponding to the clamping end of the middling clamping rod (5) which is provided with a symmetric cuniform-shaped block (9) corresponding to opening ends of the upper lever clamping arm (4) and the lower lever clamping arm (15). The supporting body (12) is provided with an elastic device which keeps the clamping ends of the upper lever clamping arm (4) and the lower lever clamping arm (15) open. The invention is an automatic follow centering and clamping device applying automatic follow and moving, automatic centering and automatic compensating to a numerical control grinder.

Description

technical field [0001] The invention relates to a clamping device, in particular to an automatic tracking and centering clamping device applied to a numerical control grinding machine. Background technique [0002] Shaft parts, especially slender shaft parts, are prone to bending deformation during grinding. Generally, intermediate clamping is required to assist positioning. The traditional method is to use two points (namely the middle and two points below the shaft) to support. The arm is manually adjusted, and fixed with screws after adjustment. This method determines the diameter of the journal after adjustment, and cannot grind the support journal itself, which limits the scope of application. At the same time, the dimensional error of the journal, The shape error will affect the support accuracy, and the wear of the support point itself cannot be automatically compensated, and can only be readjusted manually, which is poor in application process.
