The present invention relates to a centrifugal polishing machine, and more particularly, a means for driving each barrel separately, so that the posture of the barrel can be horizontally adjusted after polishing, thereby effectively performing the operation of inserting and discharging parts. The present invention also relates to a centrifugal polishing machine, which has a means for opening and closing a barrel cover by a motorized or slide type using a cylinder to increase the convenience and safety of the operation related to opening and closing the barrel.

In general, a centrifugal grinding machine is a type of grinding machine in which a part and a grinding stone are put into a barrel, and then rotated so that the part and the grinding stone collide with each other by a centrifugal force to generate a strong cutting force or give a polish.

1 to 3 show a conventional centrifugal grinding machine.

As shown in FIG. 1, the conventional centrifugal grinding machine is arranged in the circumferential direction and hinged at both sides to the central axis to support a plurality of barrels 10 capable of self-rotation and one axis while supporting the central axis of each barrel 10. To rotate the drum 11, the timing gear 12 and the timing belt 13 to guide the rotation of the barrel 10 by using the rotational force of the drum 11, and to support both ends of the drum 11 The frame 14 and the drive motor 15 for driving the drum 11 and the like.

Here, reference numeral 16 denotes an idle gear having a tension function for tension of the belt, and 17 denotes a center gear fixedly mounted to the drum shaft to serve as a center member for transmission of each belt.

Therefore, when the drum 11 is rotated by the operation of the drive motor 15, the center gear fixed while rotating the tie-mil belt 13 connected to one timing gear 12 of each barrel 10 is fixed. Since the tooth is moved relative to (17), it proceeds in one direction, and accordingly, the barrel 10 can rotate itself in the opposite direction to the drum 11, thereby enabling the polishing of the components contained therein. Will be.

As shown in Figure 2, the barrel 10 is made of a cylindrical weight that can maintain the rigidity against the force of the parts and abrasive stones in each other, and the center is rotatably centered inside the drum (11) Both ends of the shaft are supported, and the cover 19 of the barrel 10 can be held in a locked state by the locking device so as to be supported at both ends by the holder 18 attached to the body.

The locking device of the cover 19 is inserted into the groove 18a formed at the upper end of the holder 18 and locked in a cylindrical guide 20a welded and attached to the upper surface of both ends of the cover 19. It consists of an eccentric pin 21 and a lever 22 for operation, and a fixing pin 23 and a guide 20b inserted into the hole 22a of the lever 22 to maintain the locking position. As shown in Fig. 3, the lever 22 is bent upward at the same time as the fixing pin 23 is released, and then the eccentric pin 21 is pulled out of the groove 18a to release the locking state of the cover 19. It becomes possible.

Here, reference numeral 24 denotes an adjustment bolt capable of adjusting the locking force of the eccentric pin 21 that is inserted into the groove 18a of the holder 18 and locked.

However, such a conventional centrifugal polishing machine has several disadvantages as follows.

1) If the drum is erected together with the driving stop of the driving motor after grinding, the barrel's posture may not be stopped horizontally, but may become oblique, or even upside down. There was a significant inconvenience, and even if the operator stops the machine while correctly adjusting the posture of the barrel, this also has a difficult problem.

2) As mentioned above, since the cover of the barrel is a considerable weight, it is difficult for the worker to lift and lower the cover by using the handle, and there are safety accidents such as dropping sometimes. There was a lack of protection in terms of safety.

Therefore, the present invention has been devised in view of the above, and has a means for driving each barrel separately from the drum separately from the driving of the main body of the machine so that the posture of the barrel can be leveled after polishing. It is an object of the present invention to provide a centrifugal polishing machine that can effectively perform the input and discharge of parts.

In addition, another object of the present invention is to provide a cover opening and closing means to increase the convenience and safety of the operation related to the opening and closing of the barrel by opening and closing the barrel cover by the power or slide method using a cylinder. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 4 and 5, the centrifugal grinding machine of the present invention includes at least four barrels 10 arranged in the circumferential direction of the drum 11 and rotating at the same time to accommodate parts and abrasive stones therein. The drum 11 is rotated in one direction together with each barrel 10 and connected to the drive motor 15 by a belt, and the barrel 10 is rotated while being self-electrically driven using the rotational force of the drum 11. The main medium is a timing gear 12 and a timing belt 13, a plurality of idle gears 16 for maintaining the tension of the timing belt 13, a frame 14 for supporting the above components. When the drum 11 is rotated by the operation of the driving motor 15, the tmil belt 13 connected to one timing gear 12 of each barrel 10 is also rotated together, which will be described later. The center stops rotating in conjunction with the auxiliary drive motor 26 and the auxiliary center gear 25 By using the principle that the tooth is shifted in one direction with respect to the gear 17, the barrel 10 can rotate itself in the opposite direction to the drum 11.

By using the rotation of the drum 11 and the rotation of the barrel 10 in this way it is possible to polish the parts contained in the barrel 10.

In addition, both ends of the barrel 10 are rotatably supported inside the drum 11 by a central axis formed at the center of the body 10a, and the cover 19 of the barrel 10 is supported. It is possible to maintain the locked state by the locking device is configured to support both ends in the holder 18 attached to the body (10a).

At this time, the locking device can be applied to the locking device generally employed in the existing centrifugal grinding machine.

In particular, in the present invention, by providing a barrel individual drive device for the horizontal posture of the barrel 10, it is possible to facilitate the addition and discharge of parts and abrasive stones in the barrel.

To this end, as shown in Fig. 5, an auxiliary center gear 25 which is integrally operable with this is mounted on one end face of the center gear 17 mounted on the central axis of the drum 11.

Therefore, when the drum 11 is rotated by the operation of the drive motor 15, the center gear 17 also stops the tie-mil belt 13 connected to one timing gear 12 of each barrel 10. Since the tooth (으로) is moved to the axis to rotate the barrel 10 in the opposite direction while being rotated, it is possible to polish the components contained therein.

At this time, since the driving gear 27 fixed by the operation stop of the auxiliary deceleration drive motor 26 is held by the auxiliary timing belt 28, the center gear 25 is also fixed together. The state can be maintained, and thus the self-rotational movement of the barrel 11 according to the rotation of the drum 11 when the machine is running can be performed without problems.

After the grinding operation, when the driving motor 15 is erected to take out the parts in the barrel 10, the drum 11 and the barrel 10 are also stopped. At this time, the parts of the four barrels 10 as shown in FIG. When the posture of one barrel 10 in the discharge position is not correct, the posture of the barrel 10 can be corrected by operating the auxiliary deceleration drive motor 26.

That is, when the auxiliary deceleration drive motor 26 is operated as shown in FIG. 7, power is transmitted through the auxiliary timing belt 28 so that the auxiliary center gear 25 and the center gear 17 rotate, respectively. Only the barrel 10 of the can be rotated, so that when the posture of the barrel 10 in the discharge position is exactly horizontal posture, the operation of the auxiliary drive motor 26 is stopped, and then the polished parts therein can be taken out. It will be possible.
