Abstract

PURPOSE:To reduce the noise at the time of rotation, and to enable the use of drills having the same lead by providing idling wheels on the sides between respective driven gears, and also by providing toothed parts on the transmission belt surfaces corresponding to the driven gear side, so that the contact angle in the adjacent driven gears can be increased and the driven gears can be turned in the same direction. CONSTITUTION:In a multi-spindle drilling device, spindles 8 each fitted with a drill 21 at its end are arranged in a row so as to be parallel to each other, and also by separately providing each spindle 8 with an elevating means (cylinder) 19 by which an arbitrary drill 21 can be elevated or lowered. To each spindle 8, a driven gear 6 is separately arranged, and on the side between two adjacent driven gears 6, 6, an idling wheel 11 is arranged. A transmission belt 17 having toothed parts (a), (b) is wound around these driven gears 6 and idling wheels 11. The transmission belt 17 is engaged with the respective driven gears 6 to turn them in the same direction, and is interlocked with the driving gear 15 of a motor 13. Thus, the contact angle of the transmission belt can be increased, and noise can be reduced.

By selectively operating the cylinder 6' corresponding to the drilling position, the piston rod 7' is advanced, and the drive shaft 2' connected thereto is moved forward (toward the right in Fig. 4). Only the drill 3' that has been drilled is moved forward to perform drilling, and the unused drill 3' can be left in its original position. Therefore, one or more holes can be appropriately punched at a predetermined position.

(Issue 111 to be solved by the invention) As mentioned above, the conventional drilling device has no problem in terms of machining performance, but because the drive shaft 2' rotates forward and backward alternately, the same lead drill However, since the pitch between the shafts is as narrow as 30 gears as mentioned above, a small diameter gear 4' must be used.
The simultaneous rotation generates a large amount of noise, creating a problem in which the work environment is disturbed. That is, although the rotation speed of the drill is not high at about 3600 rpm, it generates heat and expands when used for a long time. For this reason, a clearance (backlash) between the gears is set in advance to avoid this, but this causes rattling of the tooth surfaces, resulting in noise.

The best solution to the above problem is to improve the machining precision (gear precision, gear mounting pitch precision) of each component, but this method requires precision that far exceeds the precision of products such as furniture components. This causes a problem in that the manufacturing cost of the device increases.
