Abstract

(57) Abstract: An object of the present invention is to easily perform switching between rough polishing and finish polishing of each polishing surface of a work having a square outer surface. SOLUTION: A work having a square outer surface is attached on a base so as to be capable of reciprocating sliding and intermittent rotation in a direction perpendicular to the polishing plane, and a vertical plate is arranged in a direction perpendicular to the axial direction of the work. A vertical polishing apparatus for a work having a square outer surface in which an endless abrasive is mounted on the vertical plate, and the vertical plate is selectively slid to press any of the abrasives against the flat surface of the workpiece to be polished. .

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for polishing a work having a flat surface to be polished along an axial direction, and in particular, it is one component of a mold used for molding an injection molded product. The present invention relates to a polishing device suitable for vertical polishing work of a work having a square outer surface.

2. Description of the Related Art The present applicant has previously proposed an apparatus for polishing a rod-shaped body shown in FIGS. 3 and 4 along the axial direction (Japanese Patent Application No. 7-64).
715). In the above apparatus, a base to which a gripping member for detachably gripping a work is attached, and a frame to which a polishing member that contacts the outer circumference of the work is attached are arranged so that the polishing member contacts the outer peripheral surface of the work. A rod-shaped drive source for moving the work and the polishing member back and forth relatively in the axial direction of the work, and a polishing member drive source for intermittently moving the work intermittent rotation drive source polishing member along the outer periphery of the work. It is a polishing device characterized by polishing a body along an axial direction.

Next, the operation will be described. Work W with endless polishing material 100 pressed against the outside of work W
Is slid back and forth by the slide device 101 and is polished in the axial direction. Next, the slide device 101 is stopped, and the polishing material 100
Is rotated to press the new surface of the abrasive material against the work W to operate the slide device 101. When changing from rough polishing to finish polishing, the polishing material 100 was changed.

[0004]

The above-mentioned prior art is for polishing a round bar, and when changing from rough polishing to finish polishing, the polishing material must be changed, which is troublesome and the external surface of the prismatic shape is square. There is a problem that it is not suitable for polishing.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to mount a work having a square outer surface on a base so that the work can be reciprocally slid and intermittently rotated at right angles to the polishing plane. Attaching, arranging vertical plates in the direction perpendicular to the axial direction of the work, arranging endless abrasives on both sides of the work and attaching them to the vertical plate, and selectively sliding the vertical plate to attach one of the abrasives to the work. It is characterized in that it is pressed against the plane to be polished.

1 and 2 show an embodiment of the present invention.
The first embodiment will be described in detail. On a slide base 2 slidably arranged on a base 1, a chuck member 3 for supporting both ends of a work W and a tail head 4 are attached.
The chuck member 3 can be intermittently rotated by the intermittent rotation member 5. Reference numeral 6 denotes a known slide device that slides the slide base 2 back and forth. A vertical plate 7 is arranged on the base 1 in a direction perpendicular to the work W, and can be manually slid along the guides 8 and 9 of the base 1. The vertical plate 7 has rough abrasives 1 on both sides of the work W.
0 and finishing abrasive 11 are guide pulleys 12 and 1, respectively
3, 14, 15, 16 and 17, 18, 20, 21 respectively. Pulley 12 and pulley 17
Is interlocked with the output shaft of the intermittent rotation member 22.

Next, the operation will be described. The work W is gripped by the chuck member 3, the vertical plate 7 is slid to the right as shown in FIG. 2, the rough abrasive 10 is pressed against the outer flat surface of the work W, and the slide device 6 is operated to reciprocate the work W. And polish in the axial direction. After the completion of polishing of one surface of the work W, the intermittent rotation member 5 rotates the other polishing plane to the polishing position to polish the polishing plane. After finishing the rough polishing, the vertical plate 7 is shown in FIG.
Is slid to the left to remove the rough abrasive 10 from the work W, the right finish abrasive 11 is pressed against the work W, and finish polishing is performed in the same manner as described above.

[0008]

According to the present invention, a work having a square outer surface is mounted on a base so as to be capable of reciprocating sliding and intermittent rotation in a direction perpendicular to the polishing plane, and a vertical plate is formed in a direction perpendicular to the axial direction of the work. Since the endless abrasives are arranged on both sides of the work and attached to the vertical plate, the vertical plate is selectively slid so that any of the abrasives is brought into pressure contact with the plane to be polished of the work. When performing rough polishing and finish polishing of each polishing flat surface of a workpiece having a rectangular outer surface, two types of suspended abrasives are selected and pressure-bonded without changing the abrasives. The work can be switched extremely easily.
