surface grinder of supporting pressure adjustment and reversing device

What is the bearing pressure adjustment and reversing device of surface grinder? Now let's talk about it.

The surface grinder has vertical movement mechanism of grinding head, longitudinal movement mechanism of worktable and transverse movement mechanism of worktable. The vertical movement mechanism of grinding head has numerical control stepping motor, which is connected with the vertical movement transmission mechanism of grinding head carriage of reducer. The longitudinal movement mechanism of worktable has reducer, and the transmission shaft of reducer is connected with the longitudinal movement transmission mechanism of worktable to reduce the speed The motor of the machine is connected with the frequency converter.

1. Adjustment of bearing pressure of surface grinder

The bearing pressure adjustment of surface grinder is to adjust the pressure of pressure relay. Generally, the range of pressure adjustment is 2-6mpa, and it 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 attached with a pressure gauge. When adjusting, press the dial to rotate the adjustment knob of the pressure relay clockwise. When the pressure rises, the adjustment knob should be relaxed. When the pressure is too high, rotate 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 It is better to tighten the regulating handle of the overflow 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

According to the different power supply used by the electromagnet, the reversing valve of surface grinder can be divided into AC type, DC type and local integral type (local rectification type). AC type has large starting force, and does not need special power supply. It can pull in and release quickly, but when the power supply voltage drops by more than 15%, the hub force will drop obviously, which affects the working reliability of surface grinder. DC type (general working voltage is 24 V or 12 V) has reliable operation, self impact, high allowable switching frequency, small volume and long service life. However, surface grinder needs special DC power supply: This machine is complete The flow pattern itself can convert the incoming alternating current into direct current and then supply it to the direct current electromagnet.

The above is about the surface grinder bearing pressure adjustment and reversing device, I hope to help you.
