Please refer to fig. 8-9.

The utility model discloses a keyway planer device floats, including above-mentioned unsteady pinch roller device, select sword cylinder 44 and floating installation. Wherein, the utility model discloses a select sword cylinder 44's piston rod to pass through floating device but set up in selecting sword cylinder 44 with the fluctuation.

The floating device comprises a two-position five-way electromagnetic valve K0, a pressure reducing valve K1, a buffer gas tank K2, a knife selecting cylinder 44 and a compressed gas source K3. Wherein, the buffer gas tank K2 and the compressed gas source K3 are fixedly connected with the knife selecting cylinder 44.

The two-position five-way solenoid valve K0 has an air supply port c1, a first working port c2, a second working port c4, a first exhaust port c3, and a second exhaust port c 5. When the two-position five-way solenoid valve K0 is in the first state (as shown in the figure), the first working port c2 is communicated with the air supply port c1, and the second working port c4 is communicated with the second exhaust port c 5; when the two-position five-way solenoid valve K0 is in the second state (as shown), the first working port c2 is in communication with the first exhaust port c3, and the second working port c4 is in communication with the supply port c 1.

The first working port c2 is communicated with an input end c6 of the pressure reducing valve K1, and an output end c7 of the pressure reducing valve K1 is communicated to an upper end port of the knife selecting cylinder 44 through a buffer air tank K2. The second working port c4 is communicated to the lower port of the blade selecting cylinder 44. The supply port c1 communicates with a compressed air source K3.

When a knife needs to be fed, the two-position five-way electromagnetic valve is electrified, the piston in the electromagnetic valve moves to the right limit position (namely, the first state) under the action of electromagnetic force, compressed gas in a compressed gas source enters the upper end of the knife selecting cylinder 44 through the buffer gas tank K2 after being decompressed by the decompression valve K1, and the gas at the lower end of the knife selecting cylinder 44 is discharged through the second gas outlet c 5. At this time, the piston rod of the blade selecting cylinder 44 descends.

When the knife needs to be lifted, the two-position five-way electromagnetic valve is powered off, the piston in the electromagnetic valve moves to the left extreme position (namely, the second state) under the acting force of the spring at the right end, at the moment, compressed gas in the compressed gas source enters the lower end of the knife selecting cylinder 44, and gas at the upper end of the knife selecting cylinder 44 is gathered in the buffer tank K2. At this time, the piston rod of the blade selecting cylinder 44 moves upward until the pressure in the blade selecting cylinder 44 rises to the working pressure.

When the aluminum plate processing device works, when the high and low parts on the aluminum plate to be processed are upwards pressed against the piston rod of the cutter selecting cylinder 44, the buffer tank K2 buffers the piston rod up and down, and the pressure of the aluminum plate on the piston rod is controlled within the working pressure range.

When the surface of the aluminum plate to be processed causes the pressure on the piston rod to be overlarge, the compressed gas in the buffer tank K2 sequentially passes through the pressure reducing valve K1, the first working port c2 and the first exhaust port c3 to release partial pressure.

Among them, the pressure reducing valve may be a pressure reducing valve without a vent function, such as an AR2000 type pressure reducing valve of SMC, or a pressure reducing valve with a vent function, such as an IR1020 type pressure reducing valve of SMC. The difference is that when the pressure reducing valve has no air exhaust function, the upper deviation of the gas pressure floating is slightly larger when the compressed gas of the buffer tank K2 is buffered; when the pressure reducing valve has a gas discharging function, when the compressed gas in the buffer tank K2 is buffered, and the gas pressure exceeds the preset pressure, part of the gas is discharged, so that the lower deviation of the gas pressure floating is slightly larger.

Wherein the pressure reducing valve is used to reduce the pressure of a relatively high-pressure gas source (e.g. 8 kg) to a working pressure (e.g. 2 kg).

In another alternative embodiment, the buffer gas tank K2 may be eliminated, and the output end c7 of the pressure reducing valve K1 is directly communicated with the upper port of the knife selecting cylinder 44. At the moment, the pressure reducing valve can only be a pressure reducing valve with an exhaust function, so that the overlarge pressure in the cutter selecting cylinder during working is avoided. After the knife selecting cylinder changes from high to low for multiple times, the pressure reducing valve needs to be repeatedly exhausted for multiple times, so that the knife selecting cylinder needs to be switched to the first state again for gas supplement.

The floating pressure wheel device can be pressed on an aluminum plate to be processed by the downward pressing of the floating pressure wheel to roll and press when the straight-groove machine head walks to perform grooving, and the pressure between the floating pressure wheel and the upper surface of the aluminum plate can be set by a pressure regulating valve arranged on the cutter selecting cylinder, namely, the floating pressure wheel floats downwards under the action of the cutter selecting cylinder, so that the contact pressure between the floating pressure wheel and the aluminum plate is kept in a small range, and further, a linear groove with the consistent depth can be formed on the non-planar aluminum plate during grooving; furthermore, the groove depth adjusting device can also be adjusted through the adjusting bolt to meet the requirements of different groove depths of the V-shaped groove, namely whether the plate to be processed is smooth or not, the groove with the same depth can be processed. The fall distance between the bottom of the floating gouging tool bit and the bottom of the floating pressing wheel is the grooving depth.

In other embodiments, the floating puck device further preferably includes a vertical scale 404g fixed to the L-shaped fixed plate 404d, and an indicator plate 404f fixedly connected to the slider 404b, the indicator plate 404f horizontally abutting the vertical scale 404 g. Like this, operating personnel can have certain height to refer to when adjusting, and this depth of slotting can be adjusted, and the scale of installing on the floating pinch roller frame can be referred to the regulation distance.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.

Other parts not described in detail in the present invention belong to the prior art, and are not described herein again.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
