Abstract

The invention discloses a non-standard part machining clamp for a precision machine tool. The clamp is characterized in that when a non-standard part to be machined is positioned and clamped, a visualdetection mechanism can scan and detect one or more surfaces or points on the top of the non-standard part, and the visual detection mechanism is used for calculating the spatial position coordinatesof one or more surfaces or points; in this way, by means of a controller, the controller can control a compensation supporting and adjusting mechanism to carry out telescopic adjustment in the heightdirection according to the spatial position coordinates calculated by the visual detection mechanism, so that accurate positioning of the non-standard part to be machined is achieved, the positioningprecision of the non-standard part is guaranteed, the clamping and positioning reliability is improved, the tool setting precision during subsequent machining is improved, and high-precision positioning and clamping and high-precision machining are achieved; and the non-standard part machining clamp for the precision machine tool effectively solves the problem that the positioning precision of floating supporting is not high, and effectively improves the machining precision.

Description

technical field [0001] The invention specifically relates to a fixture for processing non-standard parts used in precision machine tools, and belongs to the technical field of fixtures. Background technique [0002] At present, for some non-standard parts, when clamping and fixing them, it is necessary to design a special fixture to adapt to the height and position of the non-standard parts, and then realize the tool setting operation. With the continuous development of automatic processing technology and high-precision machine tools, the application of high-precision positioning and clamping mechanisms is increasing. Among them, floating support clamps are one of the more common workpiece positioning mechanisms at present. However, when the floating support fixture is positioned, because it is a floating support, the positioning accuracy is often low, and it is difficult to achieve high-precision positioning and clamping, which seriously affects the subsequent tool position...
