Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] Such as figure 1 As shown, the present invention provides a passive and compliant grinding device with multiple grinding heads. As a preferred embodiment, it includes a flange connection structure 1, three compliant grinding heads 2 and three grinding head support mechanisms 3, and the flange connection mechanism 1 is formed in a circumferential direction. Three compliant grinding heads 2 and three grinding head support mechanisms 3 are set at 120°, and the grinding head support mechanisms 3 are used to limit the swing posture of the compliant grinding head 2 . The flange connection structu...

Abstract

The invention discloses a device of passive smooth grinding of a multi-grinding head.The device mainly comprises a plurality of smooth grinding heads and corresponding supporting mechanisms, wherein the circumferential radian of the smooth grinding heads and the corresponding supporting mechanismsarearranged on aflange connecting mechanism; the smooth grinding headshavetwo degrees of freedom, swinging posesarelimited by the curvature of the corresponding supporting mechanisms and anactual workpiece, and can be independently controlled and can also be controlled in linkage;and the flange connecting structure is provided with a grinding head controller, and is used for realizing starting and stopping and pose control of theplurality of smooth grinding heads, so that the contact force betweenthe smooth grinding heads and a to-be-machined surface is adjusted. According to the device and the method, the deflection poses of the smooth grinding heads can be quickly responded according to thecomplex machining surface curvature condition, seamless fittingis realized, and high-efficiency and high-precision grinding of the workpiece is achieved.

Description

technical field [0001] The invention relates to the field of mechanical parts processing, in particular to a passive and flexible grinding device with multiple grinding heads, which is used for processing large complex curved surface parts. Background technique [0002] In the fields of aerospace, automobiles, rail transit, ships, etc., the product surfaces and power system parts are mostly complex curved surfaces. These curved surfaces cannot be composed of elementary analytical surfaces, and there are local protrusions such as reinforcing ribs. Therefore, the efficiency of complex curved surfaces is high. Quality processing has always been a difficult problem in domestic and foreign manufacturing. [0003] At present, grinding processing mainly has great advantages in the field of simple geometric parts, such as cylindrical grinding, internal grinding and surface grinding of parts. However, for the grinding and finishing of complex curved surfaces, the traditional grindin...
