Description

Barrel finishing machine and method

The present invention relates to a barrel polishing machine and a polishing method, in a barrel polishing machine in which a barrel is polished in a state in which a barrel contains abrasive stones and water, and a part itself to be polished by bonding and fixing an automobile wheel, which is a component to be polished, to an end of a rotating rod is mounted on a motor. The present invention relates to a barrel polishing machine and a polishing method which improve the polishing speed and efficiency by rotating the part and the barrel at the same time by allowing the rotation thereof.

Generally, the grinding machine includes a vibration polishing machine, a high speed centrifugal polishing machine, and a barrel polishing machine. Vibratory grinding machine is the most widely used in the field of barrel polishing as a grinding machine using the vibration and spiral motion generated by the unbalanced weight attached to both ends of the motor. Mixed workpieces such as media are polished by frictional movement in an annular barrel. It is used for finishing various surfaces from rough grinding to gloss removal, flash removal, scale removal, plating pretreatment, and polishing. .

The high-speed centrifugal polishing machine is a grinder using centrifugal force generated when the four hexagon barrel tanks are attached to the symmetrical position of the turret to rotate the rotating shaft at high speed. When rotating the turntable more than 60 ALPM, centrifugal force and pressure are generated in the mass in the barrel tank. The barrel tank rotated in the opposite direction of the turntable is Abrasion is achieved in a short time due to strong pressure and friction on the entrained workpiece. Centrifugal grinders are suitable for the grinding of relatively small products, and can be precisely polished. When the rotation speed is adjusted at the initial time, micro centrifuges can be processed even for small products that are easily broken or bent.

The barrel grinder mainly uses a rotary barrel grinder. The rotating barrel contains abrasive stones on the pellets and water to be polished together with the abrasive to be polished. Take care.

The above-described polishing machine is advantageous for polishing small parts by combining granular abrasive stones, parts to be polished, and molds by vibrating or rotating them together. However, in order to grind the bulky parts of the parts to be polished, when the bulky parts are put in the barrel and rotated, there is a problem that the surface of the parts causes surface damage due to mutual collision.

The present invention is to solve this, an object of the present invention is to rotate the barrel and the part at the same time so as to grind the bulky parts of the parts to be polished, the parts are rotated by a rotating shaft to be fixed in a fixed position To be rotated.

To this end, the present invention rotates in the inner surface of the fixed barrel and has a barrel having a rotating barrel for receiving abrasive stone and water, a rotating rod driving unit having a rotating rod to rotate by rotating the parts to be polished, and tilting the rotating rod into the barrel It is configured to include an inclination adjustment unit to adjust so as to put.

In another aspect, the present invention provides a method for uniformly polishing the car wheel to be polished by rotating the car wheel to be polished in the forward direction, and then lifted up on the barrel to stop and put back into the barrel while rotating back.

The rotating rod 40 is installed to form an acute angle (less than 90 degrees) based on the tangential direction of the fixed barrel 30. An example of the power supply unit 20 may include a rotation shaft 21 installed at the center of the lower bottom of the polishing barrel 10, a gear mechanism 22 for converting a direction in which power is applied to the rotation shaft 21 in a right angle direction; It comprises a clutch 23 for transmitting or interrupting power to the gear mechanism 22, and a motor 25 for providing the power to the clutch 23 after deceleration through the reducer 24. 47 shown in FIG. 1 is an automobile wheel which is a part to be polished. 400 is an operation panel. Abrasive stone (11) used in the present invention is generally used as a granular, rod-shaped, square, oval, etc. It is good to use a mixture that implements, which is that the shape of the car wheel itself is severely curved and the abrasive stone is large and small To contribute to the polishing respectively.

And a barrel power-providing motor driver 433 that provides rotational force.

4 is a flowchart of the present invention, in which the expansion cylinder 50 is rotated in the state in which the automobile wheel 47, which is a kind of large parts to be polished, is fixed to the coupling plate 41 at the end of the rotation rod 40. E) extending to a set distance set to reach the abrasive stone 11 (S1),

Driving the motor of the power providing unit 20 (S2);

Rotating the rotary rod driving motor 42 in the forward rotation direction for the first predetermined time (S3),

Returning the expansion cylinder 50 after the first setting time to stop the rotating rod and stretching after the second setting time (S4),

Rotating the rotary rod driving motor 42 in a reverse rotation direction for a second first set time (S5), and

After the first set time has elapsed, the extension cylinder 50 is returned to remove the polished car wheel 47 after the rotation rod 40 stops, and the step S6 of repeatedly coupling the car wheel 47 to be newly polished is repeatedly performed. .

The present invention configured as described above is coupled to the automobile wheel 47 using the coupling plate 41 in the rotating rod 40 in the right part of Figure 2 (for coupling can be combined using a screw or hook, etc.) Therefore, an example of a detailed configuration thereof will be omitted), and the cylinder 50 is extended. Then, it inclines in the dashed-dotted state to the right part of FIG. 2 (step S1). Then, the polishing barrel 10 is rotated through the motor 25, the speed reducer 24, the clutch 23, the gear mechanism 22, and the rotation shaft 21 of the power supply unit 20 (step S2). Then, the abrasive stone 11 and the water 12 accommodated therein rotate together. In this state, the rotating rod driving motor 42 is rotated until the first set time (a separate timer may be used or may be set in the control unit 420 shown in FIG. 3) elapses (step ( S3)). When the rotating rod 40 is rotated in the inclined state to the left side of FIG. 2, the wheels 47 as if the abrasive stone 11 and water 12 accommodated in the rotating polishing barrel 10 continuously push waves together. Polish the surface. As shown in FIG. 1, it is preferable that the direction in which the polishing barrel 10 rotates and the automobile wheel 47 to be polished are almost vertically in contact with each other when viewed in a plane. Preferably, the tangent of the polishing barrel 10 is preferable. It is good to have an acute angle α with respect to the direction. This maximizes the contact area between the abrasive stone 11 and the automobile wheel 47, shortening the polishing time and making the polishing surface constant.

When the first set time elapses in the step S3, the controller 420 drives the rotating rod driving motor driving unit 431 to stop the operation of the motor 42, and then drives the cylinder driving unit 432 to seal the seal. By returning the reader 50, the right state of FIG. 2 is achieved. After the second set time has elapsed, which is the time when the rotational force due to the inertia force stops due to the stop of the operation of the motor 42, the rotating rod driving motor 42 is reversely rotated, and the expansion cylinder 50 is extended again. The automobile wheel 47 is locked and polished to the mixture of the abrasive stone 11 and the water 12 (step S4). The reason for the reverse rotation of the motor 42 is to rotate the motor wheel 47 to be polished at regular intervals, so that the part to be polished is rotated for uniform polishing since the part to be polished depends on the rotation direction.

In this case, in the state in which the motor 42 is rotated in reverse, polishing is performed until the set time (first set time) has elapsed (step S5).

In the step S5, when the secondary first setting time elapses, the rotation rod driving motor is stopped, the extension cylinder is returned, and the restart command is waited (step S6). Repeat this process to polish the car wheels.

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention allows the barrel and the wheel to rotate at the same time to polish the wheel of the car, thereby rapidly increasing the number and amount of abrasive stones touching the wheel of the car, thereby increasing the polishing efficiency. As a result of comparing the polishing time with the rotation of the barrel only while the automobile wheel is fixed, the polishing time is reduced to about 4 to 6 times (which takes about 4 hours to 40 minutes). This is because the barrel and car wheel rotate, respectively, and the abrasive stone continuously rubs uniformly, but the time is accelerated by continuously accelerating and polishing the surface. In addition, the rotating rod is aligned with the moving direction of the abrasive stone according to the rotation of the polishing barrel and the lengthwise direction of the rotating rod to improve the polishing characteristics of the vehicle wheel installed at right angles to the rotating rod, thereby reducing the polishing time.

In addition, the method of the present invention rotates the car wheel to be polished in the forward direction and at the same time in reverse rotation to prevent the enormous load in consideration of inertia, etc., once ringed on the top of the barrel and stopped again to rotate in the reverse direction of the motor It also enables forward and reverse rotation, contributing to the reduction of manufacturing cost. In addition, by setting the forward rotation time, the up time, and the down time to reverse rotation, the operation time is reduced by maximizing workability.
