surface grinder of bearing pressure adjustment

The surface grinder has a vertical moving mechanism of grinding head, a longitudinal moving mechanism of worktable and a transverse moving mechanism of working mechanism. The vertical moving mechanism of grinding head has a numerical control stepping motor, which is connected with the vertical moving transmission mechanism of the grinding head carriage of the reducer; the longitudinal moving mechanism of the working table is provided with a reducer, and the transmission shaft of the reducer is connected with the longitudinal moving transmission mechanism of the working table to reduce the speed Connection between inverter and motor. The utility model has the advantages of reasonable structure, good working performance and high working efficiency.

1. Adjustment of bearing pressure of surface grinder: the adjustment of bearing pressure of surface grinder is to adjust the pressure of pressure relay. Generally, the range of pressure adjustment is 2-6mpa, which is adjusted to the level of pull rod according to the weight. The pressure relay and relief valve of the CNC surface grinder are installed on the side of the moving die at the operation side, and are attached with a pressure gauge. When adjusting, press the clockwise needle to rotate the pressure relay adjustment knob. When the pressure is too high, turn the adjustment knob anticlockwise. At the same time, release the relief valve adjusting hand of the accumulator of the CNC surface grinder to reduce the pressure to the required pressure Next, tighten the regulating handle of the relief valve of the accumulator, and then turn the pressure relay clockwise to adjust it. Do not adjust it arbitrarily without special circumstances.

2. Reversing device of surface grinder: the reversing valve of surface grinder can be divided into AC type, DC type and integral type (local rectifier type) electromagnetic reversing bag according to the power supply used by electromagnet. The AC type has large starting force, does not need special power supply, and can pull in and release quickly. However, when the power supply voltage drops by more than 15%, the hub force will obviously decrease, which will affect the working reliability of the surface grinder; the DC type (generally working voltage is 24 V or 12 V) is reliable, self impact, high switching frequency, small volume and long service life. However, the surface grinder needs special DC power supply The rectifier type has its own, which can convert the AC into DC and supply the DC electromagnet.
