(Prior art) A deburring sander that uses a cup-shaped rotating brush is used to remove burrs from aluminum alloy parts by die casting and burrs that occur when cutting cast iron parts. However, in this type of deburring sander, it is necessary to be able to correct the brush tip length when it becomes shorter than a specified value due to wear. The applicant previously filed as Japanese Patent Application No. Sho 61-146080 as a brush tip whose length can be corrected, but the conventional one grinds a stepped or tapered object to be processed. Then, there is a problem that the brush tip causes abnormal wear with a step or a tapered surface, and such abnormal wear cannot be corrected. Further, in the case of the previous application, there is another problem that the brush tip length has to be visually checked for wear and the brush tip length has to be manually corrected, which is troublesome.

In such a structure, the brush grinder (3) is moved to the brush main body (2) by the operation of the fluid pressure cylinder (5).
The tip of each segment brush (30) is lowered until it comes into pressure contact with the work on the work rotation device installed on the base with the required cutting amount, and in this state, by driving the main drive motor (8). It is the conventional practice to rotate the brush body (2) to carry out normal brush polishing, and after finishing the polishing work, lift the brush body (2) by the reverse operation of the fluid pressure cylinder (5) to attach and detach the work. It is similar to the type deburring sander, but when the brush tip is worn when the brush body (2) is raised to the normal position shown in the figure, the sensor (11) for detecting the brush end automatically The wear of the brush tip is detected and the signal is sent to the deceleration motor (10), which is automatically driven to drive the central shaft (2
4) is rotated, and the gear (2
6) and each segment brush (30) rotatably inserted into the brush insertion hole (27) of the brush holder (28) via the pinion (29) provided on the upper end of each segment brush (30). As the central shaft (24) rotates, the tubular member (23) in which the female screw portion is screwed into the male screw portion of the central shaft (24) descends and the segment brushes (30) rotate. At the same time, the brush tip length is adjusted to the normal position. This means that when the stepped or tapered surface-treated workpiece is abraded and the brush tips cause abnormal wear due to the stepped surface or tapered surface, the deceleration motor (10) moves the central shaft (24) to a required angle. If rotated slightly, the carriage (26) provided at the lower end of the central shaft (24) and the pinion (29) provided at the upper end of each segment brush (30)
Each segment brush (30), which is rotatably inserted in the brush insertion hole (27) of the brush holder (28) via the, is slightly rotated by a required angle to change the abnormal wear position.

(Effects of the Invention) As is apparent from the above description, the present invention, when the brush is worn by the polishing work and the tip length becomes shorter than the specified value, the central axis is rotated by driving the reduction motor. Each segment brush can be lowered through a tubular member that is driven up and down to easily adjust the tip length, and to grind the stepped or tapered object to be processed. Even if the brush tips are stepped or abnormally worn with a tapered surface, the center shaft is slightly rotated by the drive of the reduction motor, and the segment brush is slightly rotated via the gear and pinion at the lower end of the brush to cause an abnormality. It is also possible to correct the wear position, and in particular, a sensor for brush end detection is provided at the tip of the cylindrical cover, and a deceleration motor that rotates the central axis is automatically driven by a signal from the sensor. With this configuration, the sensor automatically detects that the tip length has become shorter than the specified value and the deceleration motor is automatically driven by that signal, so it is necessary to correct the tip length at an appropriate time. Since the tip length is automatically corrected, it has many advantages such as eliminating the need to monitor the wear of the tip and eliminating the need for any correction work. It is of great practical value as a solution to the problems of deburring sanders.
