Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0030] The modified support structure of the special-shaped surface of the grinding machine tailstock top sleeve provided by the present invention mainly includes: a top sleeve with a special-shaped surface on the outside of the cross section, a body shell with a special-shaped surface on the inside of the cross-section, and a position adjustment mechanism for the top sleeve. Specifically, such as figure 1 , figure 2 As shown, in this embodiment, the modular support structure of the special-shap...

Abstract

The invention provides a special-shaped-surface modular grinder tailstock center sleeve support structure comprising a triangular center sleeve, a special-shaped surface shell, an adjusting press plate, a pressure spring, a spring pretightening nut, a guide sleeve, an adjusting screw, a rotating hand wheel, a clamping adjusting gear and the like. The tailstock center sleeve of a grinder is mounted in a special-shaped surface support. The invention further provides a corresponding method. By using the special-shaped surface support for replacing a traditional cylindrical support structure, the special-shaped-surface modular grinder tailstock center sleeve support structure has the advantages of high radial stiffness of the center sleeve, suitability for large-sized heavy-load mechanisms, proneness to guaranteeing assembly accuracy, easiness in adjustment after wear of the support and the like.

Description

technical field [0001] The invention belongs to the field of grinding machine design in mechanical engineering, and in particular relates to a modular support structure for a special-shaped surface of a top sleeve of a grinding machine tailstock and a use method thereof. Background technique [0002] Grinding machine is the main equipment in the finishing stage of mechanical products, and its own precision has a decisive impact on the final quality of products. The position accuracy of the top sleeve of the tailstock of the grinder is a key factor affecting the accuracy of the grinder. [0003] The support structure of the traditional grinding machine tailstock top sleeve is composed of a sleeve, a dense ball frame, and a top sleeve. Each part is a cylindrical surface, which is easy to process and can achieve high processing accuracy. After the grinding machine was put into production for a period of time, the tailstock top sleeve and the supporting structure of the tailst...
