[0030] 〔Structure of machining center〕

[0031] Hereinafter, the first embodiment of the polishing brush 30 of the present invention will be described in detail with reference to the drawings. Such as figure 1 As shown, the grinding brush 30 is attached to the main shaft 12 of the machining center 1 controlled by a computer, and is used. Machining center 1 is an example of a machine tool

[0032] The machining center 1 includes an X table 6 and a Y table 8 attached to a base 2 , a column 4 integrated with the base 2 , a Z slide 10 attached to the column 4 , and a spindle head attached to the Z slide 10 . 14 , and the main shaft 12 installed on the main shaft head 14 . The X table 6 , the Y table 8 , and the Z slide table 10 are driven by motors 16 , 17 , and 18 with encoders, and can move independently in the X-axis, Y-axis, and Z-axis directions, respectively. The spindle 12 is rotated by a motor 19 with an encoder. The overall control of the machining center 1 including...

[0069] Hereinafter, a second embodiment of the polishing brush 30 of the present invention will be described in detail with reference to the drawings. In this embodiment, the structures of the brush guide 40 and the displacement mechanism 60 are different from those of the first embodiment, and the other structures are the same. Therefore, in the description of this embodiment, the positions of the same structures as those of the first embodiment are The same reference numerals are attached, and explanations about the same structures are omitted.

[0070] Such as Figure 10 , Figure 11 As shown, the brush guide 40 of the polishing brush 30 according to this embodiment does not have the elongated hole 44 , but the internal thread 45 is formed on the inner peripheral surface of the first receiving portion 42 . The brush main body 32 and the displacement shaft 62 are integrated by fastening with countersunk bolts 150 in a state where the fitting protrusion 64 is fitted into th...

Abstract

The present invention provides a polishing brush capable of repeating burr removal from the surface of a metal to be machined by polishing with high precision and continuously and automatically performing the polishing process until the brush reaches the end of the brush, and a machine tool using the same. life. The polishing brush includes a brush body (32) including a cylindrical base (34) and a linear brush extending from one bottom surface of the base (34) in the direction of the axis (100) of the base (34). The brush (36) is polished by bringing the tip of the brush (36) into contact with the surface of the workpiece and moving the brush relative to the workpiece to remove burrs present on the surface of the workpiece. In addition, the polishing brush includes a brush guide (40) that is coaxial with the axis (100) and disposed radially outward of the brush body so that the tip of the brush protrudes from the end of the brush guide; and a displacement mechanism (60) that changes the protruding length of the brush from the end of the brush guide.

Description

technical field [0001] The present invention relates to a polishing brush for removing burrs present on the surface of a metal to be processed by polishing, and to a machine tool using the polishing brush. Background technique [0002] Metal parts used in automobiles require high precision. In order to improve the precision of metal parts, it is necessary to remove burrs caused by machining more reliably by grinding. Conventionally, for deburring metal parts to be processed, a brush in which a plurality of linear abrasives obtained by impregnating and curing a resin binder into fibrous alumina are bundled is generally used. To remove the burrs, the abrasive front end of the brush is brought into contact with the surface of the metal member to be processed and the brush is rotated. [0003] Patent Document 1 discloses a grinder capable of stably exhibiting the performance of a brush-shaped grindstone by keeping the cutting amount of a workpiece using an alumina brush-shaped...
