Abstract
The invention discloses an automobile crankshaft positioning device which comprises a base and a clamping mechanism, and further comprises a pressure spring and a baffle plate mounted on the base, wherein the clamping mechanism is arranged on the base; a limiting slot is formed in the base; a plurality of positioning blocks are arranged in the limiting slot; the length direction of the positioning blocks is parallel to the width direction of the limiting slot; the bottom surface of the limiting slot and the bottom surfaces of the positioning blocks are connected by virtue of the pressure spring; the initial length of the pressure spring is greater than 2cm; the elastic coefficient of the pressure spring is smaller than 0.5N / mm; the baffle plate is positioned at one long side of the limiting slot; the clamping mechanism comprises a supporting rod, a barrel body and an ejector rod, wherein the supporting rod is connected with the base; the barrel body is connected to the supporting rod; the ejector rod is in sliding connection in the barrel body; one end of the ejector rod faces towards the baffle plate; the side surface of the barrel body is provided with a through hole; and a fastening bolt is arranged in the through hole in a penetration mode. According to the automobile crankshaft positioning device, the contact area between the crankshaft and the clamping device is increased, so that under the restriction of the positioning blocks and the baffle plate, the crankshaft is not liable to rotation, and therefore, the automobile crankshaft positioning device is suitable for various placing states of different crankshafts, and is relatively strong in universality.
Description
technical field [0001] The invention relates to the technical field of profiling devices for machine tools, in particular to a profiling clamping device for an automobile crankshaft. Background technique [0002] As the name suggests, the crankshaft is a shaft, and the shaft is curved. The car crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. [0003] Since the crankshaft has multiple inflection points and is not symmetrical along the axis, the geometric center of the crankshaft is not on the axis. When the crankshaft is placed horizontally on a certain plane and no external force is applied to the crankshaft, the crankshaft is prone to rotation due to the small contact surface between the crankshaft and the plane, and the heavier parts on the crankshaft will turn to the lowest position under gravity. ...
