The control unit is a pressure switch 116 associated with the high pressure hose 112 branched from the high pressure hose 112 between the solenoid valve 115 and the compressor 114 is driven in connection with the controller 117 by a wire. The low speed tire switch 118, the high speed timer switch 119, and the foot switch 120 are connected to the controller 117 to control the driving of the motor 107 and to operate the solenoid valve 115. 107) is converted to low / high speed by a predetermined time difference.

The pressure switch 116 detects the pressure of the air flowing into the vacuum generator 113 from the compressor 114.

The foot switch 120 is connected to the controller 117 by a wire of a predetermined length so that the operator operates by foot from the outside of the body 101.

The gas conveying unit is provided between the two vertical bars 124 and 124 'installed at a predetermined height in opposition to the left and right center portions of the square frame 123 at the four corners of the bottom wheels having the fixed lever 121. ) And bolted to the inside of the vertical bars (124, 124 ') and the outer left and right sides of the base 101 bolts and inserts both ends of the rotating shaft 127 in the shaft hole 126 to axially couple.

The axis holes 126 of the flangers 125 are positioned on the same axis.

The working angle adjusting unit forms a nut hole 128 at the lower side of the vertical bar 124 'and fastens the fixing bolt 129 to the nut hole 128, and the lower end of the fixing bolt 129 is press-fitted. It is provided with a bracket 130 having a plurality of fixing holes 131 is fixed to one side of the base 101.

At this time, the fixing holes 131 are formed at the same distance from the rotation shaft 127, the distance is the length between the shaft 127 and the fixing bolt 129.

In other words, the plurality of fixing holes 131 are formed at predetermined angles along the circumference of the imaginary circle having a radius between the shaft 127 and the fixing bolt 129 as a radius.

The port case 132 is a trumpet-shaped case having a wide bottom surface and an open top surface thereof, and being fixed to the top surface of the base body 101, the center of the bottom surface thereof being coaxial with the hollow spindle 103. Located. That is, the front end of the hollow spindle 103 is protruded into a through hole (not shown) formed at the center of the bottom surface.

Reference numeral 109,109 'is a pulley (PULLEY), 133 is the primary operation wood.

The operation of the present invention configured as described above first applies power to form high-pressure air by the operation of the compressor 114.

The pressure of the high pressure air is 4kg / ㎠.

Then, when the operator stepped on the foot switch 120 as shown in Figures 1, 5, 6, the solenoid so that the high-pressure air of the compressor 114 flows into the vacuum generator 113 along the high-pressure hose 112. The valve 115 is opened, and the vacuum generator 113 is operated by the inflow of high pressure air, after which the high pressure hose 112, the inner space of the rotor jointer 110, the hollow part of the hollow spindle 103, the metal disc. A vacuum is caused in the space 'B' from the through hole 106 'of the 104 to the through hole 106 of the rubber disc 105.

In the above state, when the bottom surface of the wood 133 is in contact with the top surface of the wood 133 so that the through hole 106 of the rubber disc 105 is blocked, between the bottom surface of the wood 133 and the other surface The wood mill 133 is strongly adsorbed and fixed to the rubber disc 105 by the support of the metal disc 104 by the pressure difference acting on.

Therefore, the wood machine 133 is fixed to the adsorption unit by vacuum adsorption, so that it is easily fixed without being limited in shape.

In this case, as shown in FIG. 2, the woodworker 133 may be easily centered on the basis of the concentric pattern 111 formed on the rubber disc 105.

In addition, the driving motor 107 is operated simultaneously with the opening operation of the solenoid valve 115, the rotational speed of the drive motor 107 is shown in Figure 4 low-speed timer switch 118 and high-speed timer switch 119 The first three seconds are rotated at low speed and then operated at high speed.

In addition, the hollow spindle 103 connected to the drive motor 107 and the drive belt 108 and the metal disc 104 and the rubber disc 105 which are adsorption portions at the upper end thereof are also converted to high speed rotation after low speed rotation.

The conversion of the driving motor 107 to a low / high speed with a predetermined time difference is to fix and fix the adsorption unit to rotate the wood machine 133 at low speed rotation.

As described above, the wood machine 133 fixed to the adsorption unit smoothly processes the surface of the wood machine 133 using a grinding tool not shown by the operator at high speed by the driving motor 107.

In addition, the present invention, in addition to the surface polishing of the wood mill 133, it is also possible to cut the wood mill 133 to a specific shape using a cutting tool (not shown).

At this time, the wood group 133 is able to process and grind all surfaces except for the bottom part due to the characteristics of the fixed state.

When the wood mill 133 is rotated at a high speed in a state where the adsorption unit is fixed to the adsorption unit, the pressure of the air supplied from the compressor 114 to the vacuum generator 113 is reduced to an appropriate pressure (4 kg / cm 2) or less. When the pressure switch 116 detects this, the controller 117 intercepts the operating power of the driving motor 107 and stops the rotation drive.

In the control operation as described above, when the high pressure air supplied from the compressor 114 to the vacuum generator 113 is reduced to less than an appropriate pressure (4 kg / cm 2), the operation of the vacuum generator 113 is reduced, and as such, Since the fixed adsorption force of the fixed wood group 133 is dropped, the wood group 133 is separated from the adsorption unit in the high-speed rotation, thereby causing a safety accident, the pressure switch 116 in order to prevent the occurrence of such a safety accident When the pressure of the high-pressure air flowing into the vacuum generator 113 is sensed and the pressure drops below an appropriate pressure (4㎏ / ㎠), the operation of the driving motor 107 is stopped.

And by processing and grinding the rotating wood 133, by-products are generated and such by-products are scattered around by centrifugal force, and the by-products are prevented from being widely scattered by the port case 132, and stacked therein. This prevents the gas 101 and the apparatus therein from being contaminated and prevents the workplace from being polluted.

Thereafter, when the processing of the wood mill 133 is completed and the foot switch 120 is off-off, the driving motor 107 is first off-off and the rotational drive is stopped within a predetermined time, and then the solenoid valve 115 is removed. Is operated to block the pneumatic air delivered from the compression to the vacuum generator 113, the removal of the wood mill 133 is completed in the adsorption part is completed.

In addition, the working angle of the base 101 is changed to facilitate the operation according to the physical condition of the worker and the processing conditions of the wood machine 133 before the operation, and the operation is performed by first setting the base 101 about the rotation axis 127. After rotating at an angle, the tip of the fixing bolt 129 is advanced along one side of the base body 101 along the nut hole 128, and the tip is the same axis among the plurality of fixing holes 131 formed in the bracket 130. 127) By pressing in the fixing hole 131 located on the line, the base 101 is variable and fixed at a desired working angle.

In addition, it is possible to freely move the body 101 to a certain place and work in that position as the transfer wheel equipped with the wheel (122).

At this time, the wheel 122 is fixed by the fixing lever 121 to suppress the movement, so that the body 101 does not move at that position and then polish the wood 133.

As described above, the present invention has a vacuum suction type clamping the wood when grinding the wood, the clamping operation is easy without being bound to the shape of the wood, the time is reduced and the processing limit of the wood is minimized The workability is improved, and the existing wood grinder is used to prevent the phenomenon that the rotating workpiece is sloped during processing due to the lowering of the clamping force to prevent the occurrence of safety accidents. Working efficiency is improved by adjusting the gas to the proper working position and working condition.
