４を同期回転駆動する。Now, the elevating and lowering means for the 9let mounting table 15 is formed by the Sol screw mechanism composed of the vertical feed screw shaft 14 and the nut 16, as described above. According to this embodiment, a feed screw shaft drive means is provided on the base 1o to synchronize and drive the feed screw shafts 14 provided at the four corners of the base 10 to rotate at the same speed. . This feed screw shaft drive means includes a rotary drive source 25 consisting of a serze motor provided in the front position of the base 10, a worm 26 attached to the output shaft of this rotary drive source 25, and a worm wheel 27 meshed with the worm 26. This speed reduction device 28 and this speed reduction device 2
Two drive sprocket shafts 30 and 31 that are rotationally driven from 8 through a gear mechanism 29, sprockets 32 and 33 attached to these drive sprocket shafts 30 and 31, and tension provided at appropriate positions on the base 10. 34 and 35, driven sprocket 36 provided at the lower end of each feed screw shaft 14, and two sets of chains 37 and 38 wound around these sprockets.
It is configured to include various devices such as a set of chain transmission mechanisms 39 and the like. That is, the rotational driving force of the rotational driving source 25 is transmitted to the two drive sprocket shafts 30, 31 by the gear mechanism 29 after passing through the reduction gear 28 as two rotational driving forces having the same driving force although the rotational directions are different from each other. Ru. As is clear from the illustration in FIG. 3, the rotational driving force transmitted to the two drive sprocket shafts 30 and 31 is balanced with each other through two sets of chain transmission mechanisms symmetrical about the approximate center line of the pallet platform 15. The feed screw shaft 1 is used as the rotational driving force.
4 is driven to rotate synchronously.

The number of rotations of the output shaft of 28 is detected by a well-known tachometer mounted on the same output shaft, and the pallet mounting is performed by a control device that has previously stored the relationship between the number of rotations of the output shaft of the reduction gear 28 and the vertical position of the pallet mounting table 15. 1 unit
It is also possible to detect the actual upper/lower positions of 5, particularly the lower setup) position and the upper/glet transfer position. In addition, by detecting the position of the pallet platform 15 in this way, the electromagnetic brake 60 (FIG. 2) provided on the feed screw shaft 14 is operated according to the detection signal, and the pallet 40 is transferred to the work table 50. The pallet rest 15 can be stopped at the correct upper pallet transfer position for the purpose of transporting the pallet. Reference numeral 61 is an oil pan, which is provided to receive dripping oil adhering to the workpiece, and to collect it in one place via a ramp.
