Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0031] see Figure 1 to Figure 5 , CNC camshaft grinding machine, including machine tool 1 and electric spindle 2, the electric spindle is an electric spindle with an external planar joint hydrostatic bearing, and its outer box body adopts a closed cavity structure without leaving a window for oil pipe installation to enhance its integrity .

[0032] When using a high-speed CBN grinding wheel, the grinding wheel spindle can use a φ100mm high-rigidity, high-strength nitride steel spindle, and the bearing adopts an external plane gap throttling. The dynamic and static pressure oil chamber structure makes the grinding wheel spindle bearing stiffness up to 150 kg / micron.

[0033] The main shaft bearings include the main shaft front bearing 3 and the main shaf...

Abstract

The invention provides a computer numerically controlled (CNC) camshaft grinding machine comprising a machine tool and an electric main shaft, wherein the electric main shaft is an external plane section flowing hydrostatic bearing motorized spindle, a sealed cavity structure is adopted for an outer box body, an oil pipe installation window is not reserved, and integrity of the CNC camshaft grinding machine is enhanced; a spring is loaded between an oil cylinder and a cocket centring, an oil cylinder piston is connected at the upper end of the spring, and the cocket centring is connected at the lower end of the spring; the width of a grinding carriage installation part of the machine tool is enlarged by 1/5-1/6, and inner rib plate arrangement is optimized; and the ratio of the distance from a guide rail to a lead screw, and a whole span is widened to 0.3-0.33, and the guide rail is a guide rail for a machine tool body and a padding plate. According to the CNC camshaft grinding machine, grinding wheel linear velocity is enhanced by strengthening machine tool intensity, and therefore grinding machine working efficiency is increased by 5-10 times.

Description

technical field [0001] The invention relates to the field of numerically controlled grinding machines, in particular, to a numerically controlled camshaft grinding machine. Background technique [0002] Camshafts are important parts of automobile engines and other internal combustion engines, and their processing quality directly affects the quality of automobiles. At present, many domestic manufacturers still generally use ordinary grinding wheels to grind camshafts. This camshaft grinding method is difficult to meet the requirements of high precision, high efficiency, high flexibility and process concentration in the modern automotive industry. Numerical control cubic boron nitride (CBN) camshaft grinding machine has the characteristics of high precision, high efficiency, high flexibility, and concentrated process, and has been gradually applied in the modern automobile industry. [0003] Due to the different CNC forming methods, there are two types of CNC camshaft grinde...
