A system in which a belt is reciprocally slid on each pulley to polish the surface of the sample W is known.

[0003]

However, since the above-mentioned conventional automatic polishing apparatus operates the belt and the entire supporting mechanism thereof, the entire apparatus becomes large, and the reciprocating mechanism is heavy and accompanied by vibration. Since the belt mechanism is operated, it is difficult to uniformly and accurately grind the sample surface, and it is difficult to manufacture the supporting mechanism because it requires high accuracy, and it is expensive. Further, in the case where a belt is provided above the sample W and slidably reciprocated on the pulley in the lateral direction, the belt is easily worn at an early stage, and it is difficult to obtain a desired polishing state due to sagging due to slack in the belt. There is.

In any case, the conventional method causes the size of the entire apparatus to be increased, and there is a problem that an inspection using this type of apparatus or a laboratory requires a lot of space. SUMMARY OF THE INVENTION Therefore, the present invention is intended to solve the above-mentioned conventional problems and to provide a polishing apparatus capable of performing a highly efficient and safe work while reducing the size of the apparatus.

[0005]

Next, the mode of use and the operation of the embodiment constructed as described above will be described. The sample W has various shapes such as a disc shape and a column shape, but as a general type that is mass-produced as a sample at the time of steel making, the sample W is gripped at the center of one side of the disc body W1. Surface polishing of the T-shaped sample W integrally formed with the protrusion W2 is performed as follows. First, when the vise device 4 of FIG. 1 is in the set state of the solid line, the handle 7b is loosened to fix the fixed vise 7.
The gripping projection W2 side of the sample W is inserted between a and the movable vise 7c, and the handle 7b is rotated to fasten and fix the outer periphery of the disk body W1. (FIG. 4) In this case, the setting of the sample W on the vise 7 is extremely easy because the fastening surface of the vise 7 is in the standby posture in the upward direction, and the polishing section 6 which is rotated is operated. Since the work can be performed on the other side separated from, the work can be performed with peace of mind while ensuring good safety work.

In this way, the setting of the sample W is completed,
Next, when the automatic operation switch 30 is turned on, the following operations are automatically performed in sequence. That is, the vice 7 to which the sample W is fastened is moved by the rotating cylinder 12 so that the vice device 4 is rotated 180 degrees to the right to bring the sample W into the state of the dotted line A, and the belt 20 started to rotate by the motor 17. While facing the polishing surface, the stopper cylinder 14 pushes the pin 16 out and inserts it into the stopper hole 15 to fix the vice device 4 at that position.

In this state, the pressing cylinder 9 operates together with the vise 7 so as to lower the sample W downward, and the surface of the sample W is moved to the belt 2 by the pressure set by the pressure setting device.
When it is pressed to 0, the vise 7 is reciprocated in the width of the belt 20 with a predetermined stroke from the dotted line a to the a by the operation of the lateral movement cylinder 10 accordingly. Therefore, the surface of the sample W fastened with the vise 7 is brought into contact with the polishing surface of the belt 20 guided by the receiving plate 21 with a proper posture and an initial rough polishing pressing force, and the surface polishing is good at the set time. It is done to. When the above-mentioned rough polishing is performed for a set time, or when the pressing force is detected, the stopper cylinder 14 causes the pin 1 to move.
When the engagement of 6 is released, the rotary cylinder 12 is operated to reverse and return the vise device 4 to the original position.

When this state is reached, the valve 48 is actuated, spraying cooling water from the nozzle pipe 25 and spraying it onto the sample W that generated heat during polishing to cool it. After this, the vice device 4 again turns to the polishing posture by the same operation as described above, and this time the pressing cylinder 9 and the lateral movement cylinder 10 are operated by the pressure operation set appropriately for the finish polishing process, and the sample W is slowly moved. This is for finish polishing with a fine finish, and when these series of polishing operations are performed, the vice device 4 returns to the original set state position and the device is stopped. Here, the worker loosens the handle 7b, removes the sample W from the vise 7, attaches a new sample W, and again operates the automatic operation switch 30.
Is turned on, and the continuous polishing work of the sample W can be satisfactorily and safely performed.

In the embodiment, the case of polishing the sample W during the steelmaking was described, but the polishing apparatus of the present invention may be used as a polishing apparatus for processing general mechanical parts, and the structure of the polishing section may be changed. Instead of the belt polishing band, this part may be a vertical axis rotary grindstone.

[0018]

As described above, according to the present invention, the vice device is pivotally supported on the machine base by having the reversing mechanism, and is provided through the reciprocating mechanism for reciprocating the vise in the lateral direction. When the vise is on the other side of the polishing section, the sample W can be held and the polishing work can be performed when the vise is on the polishing section side, so that the precision of the finished surface can be improved while reducing the size of this type of polishing apparatus. In addition, it has the effect of performing safe work with high efficiency.
