Abstract

(57) [Summary] [Purpose] Make the table freely accessible from the stage. [Structure] On a stage (6), a primary side core (1) in which a primary winding (3) is elongated and vertically wound is attached to both ends in the longitudinal direction. The secondary core (2) around which the secondary winding (4) is wound is fixed to the table (5). Table (5) is
It is detachably attached to a table moving part (7) which is movable with respect to the stage (6) along the longitudinal direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a direct-acting contactless power supply device which is improved so that a moving part can be easily replaced in a mobile device or a machine tool having a moving table.

[0002]

[Prior art]

 Conventionally, a direct-acting type contactless power supply device is as shown in FIG. In the figure, 9 is a table, 10 is a power feeding core, 11 is a table moving part, 12 is a stage, 13 is a ball screw, 14 is a primary winding, and 15 is a secondary winding. The table moving part placed on the stage moves on the stage with a ball screw, and the primary winding and the secondary winding wound in a long and slender manner inside the stage, and the core around which the power is transmitted, the table is moved. Electricity is supplied to the electrically driven jigs and tools installed on the top.

[0003]

[Problems to be solved by the device]

 However, in the prior art, since the primary winding 14 is inside the core (secondary core) 10, the table 9 cannot be removed from the stage 12 and the power feeding device cannot be removed.・ There was a problem that the tools were limited (when the bolts 16 that fix the table 9 are removed, the core 10 will hit the primary winding 14, so it is practically impossible to remove the table 9) . Therefore, an object of the present invention is to provide a direct-acting type contactless power supply device that can freely take out a table from a stage.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the present invention relates to a direct-acting contactless power supply device for transmitting electric power from a primary winding to a secondary winding by high frequency induction, in which a primary winding (3) is elongated and vertically wound. A stage (6) having side cores (1) attached to both ends in the longitudinal direction, a table (5) having a secondary side core (2) wound with a secondary winding (4) fixed thereto, and the longitudinal direction The table (5) and the table moving part (7) which can be attached to and detached from the stage (6) along the table (6) are provided.

[0005]

[Action]

 By the above means, the primary side and the secondary side become independent, and the table fixed to the secondary side can be freely taken out from the stage on the primary side.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an independent direct-acting type contactless power feeder, and FIG. 2 is a side view. In the figure, 1 is a primary side core, 2 is a secondary side core, 3 is a primary winding, 4 is a secondary winding, 5 is a table, 6 is a stage, 7 is a table moving part, and 8 is a ball screw. The primary side core 1 is mounted in the stage 6 via the resin 17 with the primary winding 3 wound in the longitudinal direction. A table moving unit 7 that moves with a ball screw 8 is provided below it. The table 5 is detachably fixed to the table moving unit 7 by a fixing tool such as a bolt 16. A secondary core 2 is attached to the table 5 so as to cover the primary core 1, and a secondary winding 4 is wound in the same direction as the primary winding 3. The gap between the primary side core 1 and the secondary side core 2 is controlled so as to be close to the limit where they do not come in contact with each other, and the leakage flux is eliminated as much as possible. When removing the table 5 from the stage 6, the bolt 16 is removed, and the table 5, the secondary core 2, and the secondary winding 4 are removed as a unit. Since the secondary core 2 functions as a leg of the table 5, it is possible to place the removed one on a flat surface and set the jig / tool on the table 5.

[0007]

[Effect of device]

 As described above, according to the present invention, the table can be easily removed, so that the jigs and tools can be easily replaced for each table, and a single stage can be used for versatile work. There is an effect that you can.
