JPS5828460A - Finish processing device for curvatures of a work - Google Patents

Abstract

PURPOSE:To perform good-quality finish processing on curvatures of a work by holding the grinding wheel always in parallel with the undersurface of grinding head through its inclination in compliance with any occurrence of grinding wheel's inclination and thereby assuring that the grinding wheel contacts curvatures of the work evenly. CONSTITUTION:Grinding wheel 4 at the undersurface of the grinding head 8 is put in contact with a curvature (b) of the oversurface of a work (a) to be ground, and is given reciprocative motion to the right and left by a rotary tool 1 with the aid of a grinder holder 5 and a slider 3. Being provided with feeds, the grinding wheel 4 inclines to the left or right in compliance with bend of the curvature (b). The inclination is sensed by a couple of servo valves 15 on the right and left to produce a motion in compliance with the motion of a pair of pistons 13 on the right and left, and the grinding head 8 is given the corresponding rightwise or leftwise inclination to follow automatically. Thus the grinding wheel 4 reciprocates always at the undersurface to the right and left parallelly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus which uses a nine-metal piece as a workpiece to be mainly cut and finishes its curved surface with a grindstone.

Conventionally, this type of finishing process has generally been carried out manually using a sander, which has the disadvantage of inefficiency.The purpose of the present invention is to obtain a device that does not have such disadvantages. A machining head consisting of a slider that reciprocates left and right in conjunction with a tick rotary machine, and a grindstone holder with a lower Wa grindstone supported on a slider so as to be tiltable left and right against a spring, is attached to a four-wheel guide in the vertical direction. A support rod which can be raised and lowered and which is engaged with the upper @O bracket) is pivoted to the left and right and is connected to the bracket via a pair of left and right hydraulic screws. Each piston is arranged to face an operating plate on the upper surface of the grindstone holder on the lower side of each of the pistons, and to be able to move up and down in conjunction with the operating plate.

Embodiment 01 of the present invention will be explained with reference to the attached drawings.
) indicates an Anymatic rotary tool, which is equipped with a slider (3) on the lower side of a housing (2) having the tool (1) on the upper surface, which reciprocates from side to side in conjunction with the housing (2), and a slider (3) on the lower side that reciprocates from side to side in conjunction with this A grindstone holder (5) having a grindstone ((
It is made to be able to tilt left and right against force, thus forming a processing head (8) as a whole. The head (8) is provided with a pair of left and right guides in the vertical direction on its upper plastic bracket (9). The support frame Ql) 0, which can be raised and lowered and is engaged via a four-legged frame aQ, is pivotally supported on the front surface of the bracket (9
) are connected via a pair of left and right fluid pressure screws (13), and the vertical movement of the screws (13) causes the machining head (8) to move around the axis α2. 9. Left and right tilting, or even vertical movement along the axis α2, is provided.

Sho 1w! A pair of pistons α3 (13 is the bracket (9)
) A pair of left and right cylinders α (each servo that fits inside a◆ and extends downward and controls it in the +O downward direction) are equipped with 4 loops Q5Q5, and each red extends downward from each spool inside. (15m) (15m) on the upper surface of the grinding wheel holder (5) with (15m) on its lower side (O). When tilting, the red (15m) (
15m) is pressed on the corresponding side and detects this pipe, and the bison (13) causes a corresponding operation on the corresponding side.In other words, the head (8) It should be possible to give a corresponding tilting or vertical movement.

Furthermore, the bracket (9) is pivotally supported on the upper zero machine frame I by an axis α field, so that it can be tilted back and forth, and can be fixed at any tilted position with a screw (i9 or other means).
Furthermore, when using the machine frame (L?), for example, as shown in the fourth figure, the tip of the balance arm (to) (fixed and movable, or attached to the spindle of the shaping machine Qυ as shown in the fifth figure). It is good to be able to fix it and give an appropriate feed.

To explain its operation, the first processing head (8) is moved downward, and the lower grindstone (4) is brought into contact with the curved upper surface of the work piece. The rotary tool (11) gives left and right reciprocating motion via the slider (3), and thus the curve m'b is finished by the grindstone (4), which is then fed. Considering the given case, the grindstone (4) tilts to the left or right according to the curved surface bO.At this time, the inclination is detected by the pair of left and right servo pulps (to) on the upper side, and An operation corresponding to zero is produced, and thus the machining head (
8) is given a corresponding leftward or rightward inclination and automatically follows it. The grinding wheel (4) is always reciprocated from side to side parallel to this on its lower surface. Thus, according to the present invention When the grindstone is tilted, the machining head follows and tilts to keep the grindstone parallel to the lower surface of the grindstone, and the grindstone is always in uniform contact with the curved surface of the workpiece. Good machining can be obtained, and it has the effect of making one work simple and highly efficient.
