Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The present invention is an abrasive belt grinding mechanism with adjustable contact stiffness, the structure is as follows figure 1 As shown, it includes the servo control module and the cutting motion module erected on the upper part of the servo control module. The servo control module drives the three-axis commutator 2, the two-axis commutator A14, the two-axis commutator B16, and the two-axis commutator through the servo motor 1. The commutator C25 converts the direction of rotation, so that the screw A4 and the screw B12 produce rotational motion in different directions, and drives the nut pair A7 and the nut pair B9 to make a linear motion on the guide rail A6 and guide rail B10, and then drives the cutting motion module. The abrasive belt grinds the contact wheel for stiffness adjustment.

Abstract

The invention discloses an abrasive belt grinding mechanism with adjustable contact stiffness, which comprises a servo control module and a cutting movement module erected on the upper part of the servo control module. The servo control module drives a three-axis commutator and a two-axis commutator through a servo motor. A, two-axis commutator B, and two-axis commutator C convert the direction of rotation, so that the screw A and the screw B produce rotational motion in different directions, and drive the nut pair A and the nut pair B on the guide rail A and the guide rail. B makes a linear motion, and then drives the abrasive belt grinding contact wheel of the cutting motion module to adjust the stiffness. The invention solves the problem in the prior art that it is difficult to carry out on-line control on the processing process of curved surfaces with different thicknesses in abrasive belt grinding.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing and processing of curved surfaces, and in particular relates to an abrasive belt grinding mechanism with adjustable contact stiffness. Background technique [0002] With the progress and development of automobile manufacturing, aerospace and modern manufacturing, the surface processing quality, precision, integrity and The smoothness puts forward higher requirements. As a semi-finishing / finishing process, abrasive belt grinding plays a key role in the processing quality of the workpiece. [0003] Difficult-to-machine material curved surface components have poor thickness consistency and have different normal stiffness at different positions, while the processing trajectory of abrasive belt grinding is usually planned along the normal direction of each point on the curved surface, which fixes the traditional abrasive belt grinding The mechanism has poor adaptability to complex profi...
