駆動軸の高さを迅速に且つ確実に調節することの
できる装置を得ることを目的としたものである。 Conventionally, this type of drive shaft had the lower end thrust bearing fixed directly upright on the machine frame, but the drive shaft was cut to a certain length in advance, and the machine frame was finished with black leather. , the height of the upper end of the drive shafts, which are installed in parallel on the machine frame, is not constant, causing variations in the transmission from the drive source, the operation of the eccentric cam, and the transmission to the polishing plate. Adjustment work is required, which has the disadvantage of reducing production efficiency and affecting machine reliability. The object of the present invention is to overcome these drawbacks and provide a device that can quickly and reliably adjust the height of the drive shaft with a simple structure.

る。 The structure of the present invention will be described in detail with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a drive shaft, an eccentric cam plate 2 is attached to the upper end of the drive shaft for rotating the polishing plate, and a drive shaft is attached to the middle part of the drive shaft. A pulley 3 is attached to receive rotation from a source, and a bearing 4 is further attached to the lower end. Reference numeral 5 denotes a bearing fitting, and a machine frame A is provided on both sides of the rectangular board 6.
Attachment holes 7, 7 are bored for fixing to the cylindrical body, and a short cylindrical body 8 in the shape of an open circle is erected in the central part of the body, and the short cylindrical body 8 with one side open is erected, and both end parts of the circle are facing each other. , the tightening pieces 10, 10 having a hole 9 for tightening are integrally extended, and the diameter of the short cylindrical body 8 expands and contracts so that both the tightening pieces 10, 10 can come close to each other. Cut portions 11, 11 are formed between the lower end of 8 and the substrate 6.

を示す。 Reference numeral 12 denotes an eccentric arm whose base end is attached to the slide groove 13 of the eccentric cam plate 2 so that the amount of eccentricity can be adjusted freely, and whose tip is attached to one end portion of the polishing plate mounting frame 14. 15 is a polishing plate and hairpin 1
6 to the tip of the polishing plate mounting frame 14. 17 is a fitting consisting of a bolt and nut for attaching the bearing fitting 5 to the machine frame A; 18 is a tightening piece 1;
0 shows a fastener consisting of a bolt and nut that is attached to the 0.

ベアリング4をその外周より均一に挾着固定す
る。 With this structure, the bearing fitting 5 is attached to the machine frame A by inserting the fitting 17 into the hole 7.
Next, the bearing 4 at the lower end of the drive shaft 1 is attached to the short cylindrical body 8.
By inserting the fastener 18 into the holes 9, 9 of the fastening pieces 10, 10 and tightening it, while maintaining the height of the upper end of the drive shaft 1 at a predetermined height, both fasteners can be tightened. Attachment piece 1
0 and 10 are close to each other, and the diameter of the short cylindrical body 8 is reduced, so that the bearing 4 is evenly clamped and fixed from its outer periphery.

る。 As described above, the present invention not only allows the height of the drive shaft to be easily moved up and down, but also allows the bearing to be reliably clamped and fixed simply by tightening the clamping piece at a predetermined position. There is no need for adjustment work such as hitting the drive shaft with a mallet, and extremely precise fine adjustments can be easily made, resulting in high work efficiency and the ability to keep the machine operating smoothly and uniformly, ensuring high reliability. You can get expensive machines. Furthermore, even if the height of the eccentric cam plate and the polishing plate mounting frame fluctuates due to wear caused by use of the machine, readjustment can be easily performed.
