Abstract

PURPOSE:To improve the assembling property at the time of fixing a rack by positioning the rack with use of a positioning sleeve. CONSTITUTION:The rack positioning sleeve 2 is inserted into a hole a drilled on a carriage 1 and the hole A' on the rack 3 to decide the position of the hole A' on the rack 3. A screw 4 is inserted into a washer 5 to tighten it. Here the face B of the carriage 1 shall be located at the side where the rotation of the rack is inhibited at tightening the screw 4. After the rack is positioned by tightening the screw 4, a screw 6 shall be fastened.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ラックおよびピニオン方式のヘッド位置決め

。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for fixing a rack to a carriage in a rack and pinion type head positioning device.

〔従来の技術〕[Conventional technology]

た。The method of positioning the rack relative to the carriage in a conventional rack and pinion type head positioning device is as follows:
As shown in Figure 2, B and C processed into the carriage 1
, D, and a method of tightening the screw 7 while simultaneously pressing the rack 3, or a method of using a jig.

となり、さらに発塵をきらう装置の場合には致命的な問
題となっていた。However, the conventional rack positioning method has problems in that it is difficult to assemble and requires the use of a jig, which increases the product cost. Additionally, when tightening the screws, the rack may shift from the positioning surface, resulting in poor rack mounting accuracy. If the accuracy of the mounting position of the rack is poor, the rack and pinion will be in uneven contact with each other in the height direction, and the rack will wear out quickly. If the rack wears out quickly, the off-track of the head due to rack wear becomes a very serious problem, and it becomes a fatal problem if the device is sensitive to dust.

また、水平方向については、キャリッジシーク方向の度

いう問題点があった。In addition, in the horizontal direction, when the perpendicular position in the carriage seek direction is performed on one surface of the rack and one surface of the main seven frames, there is a problem in that the precision of the head position f deteriorates.

そこで本発明は従来のこのような問題点を解決するため

[Embodiment] An embodiment of the present invention will be described below based on the drawings.

あと、締め付ける必要がある。In FIGS. 1 and 3, the rack positioning sleeves 2 are inserted into the six holes made in the carriage 1. The hole A' of the rack 3 is inserted into the sleeve 2, and the position of the hole A' of the rack 5 is determined. Place washer 5 on screw 4 and tighten. Here, the B side of the carriage 1 must be on the side that prevents rotation of the rack when tightening the screws 4. In addition, screw 6
must be tightened after the rack is positioned by tightening the screws 4.

This has the effect that the head position stirrup accuracy can also be made very high.
