The present invention relates to a brake disc and a drum polishing machine for a vehicle which can eliminate uneven wear and improve braking force by increasing surface friction.

In general, a vehicle is equipped with a brake device for generating a braking force, and includes a disc brake and a drum brake.

The disk and drum used in the brake device are manufactured by a conventional casting process, and are not heat treated separately, and thus have low strength. When the brake is frequently operated while driving, heat is generated due to friction due to contact with the brake pads. Done.

Therefore, when braking of the vehicle is performed, partial wear or bending occurs due to natural or artificial cold heat due to contact between the brake disc and the drum surface and the brake pad.

As described above, when abnormal wear phenomenon occurs on the disk and drum surface of the brake device, smooth braking is not achieved during braking, pushing occurs, shaking of the pedal pedal, or brushing of the vehicle body. In addition, noise is generated during braking and steering of the steering wheel may occur during low speed driving, which may cause anxiety to the driver when driving, thereby causing a dangerous situation or a safety accident.

If such brake discs and drums are subjected to uneven wear or bend in the brake device of the vehicle, the discs, drums or brake pads must be replaced.

The grinding | polishing machine 1 which concerns on this invention can process and grind not only the vehicle brake disk and drum but also the surfaces of the power transmission disk used for various power transmission devices, various wheels, etc. As mentioned, of course, the clamp can be fixed and rotated, and it can be easily processed using a disk processing unit or a drum processing unit.

Referring to the use state according to the embodiment for a vehicle brake disk and a drum polishing machine of the present invention as follows.

1 to 5 (b), the clamp 20 is coupled to the front end of the rotary shaft 12 rotated by the electric motor M1, the rotational force by the electric motor M2 is a transmission portion ( 36 and the gear unit 35 are transmitted to the first and second drive shafts 40 and 60 so as to move forward and backward in the longitudinal direction or in the transverse direction, and the disc processing unit at the front end of the first drive shaft 40. To the surface of the drum or the disk of the brake used for braking force of the vehicle, using the grinding machine 1 is coupled to the 70, the drum driving unit 80 is coupled to the second drive shaft (60) First, the disk to be processed is fixed to the rotating shaft 12 using the clamp 20 to be rotated.

In this state, the disk machining unit 70 is fitted to the first drive shaft 40 installed in the second body 30, and the position of the shift lever 37 of the speed change section 36 is adjusted to the gear shift setting groove 38. Located on one side, the transmission gear 34 and the first gear 32 of the gear unit 35 is engaged.

At this time, the disk processing unit 70 forms an opposite shape and the end of the bite 74 coupled to the fixed chuck 72 is in close proximity to both surfaces of the disk, using the width adjusting port 75 Thus, the end of the bite 74 is in contact with the surface of the disk is to be surface processing.

In this way, the disk 12 is coupled and rotated by the clamp 20 in the rotating shaft 12, the disk processing unit 70 is coupled to the first drive shaft 40, the rotational force by the electric motor (M2) When the first gear 32 is rotated through the transmission part 36 and the gear part 35, the longitudinal drive screw 42 is rotated so that the second body 40 follows the driven guide shaft 43. The disk surface is cut by the bite 74 while moving forward and backward in the longitudinal direction.

Since the disk processing unit 70 has a form in which a pair of bites 74 are opposed to each other, both surfaces of the disk are processed at the same time, and in particular, the position of the bite 74 by the width adjusting slot 75. Since adjustment is made, the thickness to be cut of the disk can be easily adjusted.

And, the surface roughness of the disk by the disk processing unit 70 can be arbitrarily freely adjusted by the user. In particular, the roughness of the disk surface is somewhat roughened to improve the braking force by increasing friction with the brake pads during brake operation. It is.

On the other hand, the grinding machine 1 according to the present invention is to process not only the brake disk, but also the brake drum surface, as shown in the accompanying drawings 5 (a), 5 (b), first, the drum to be processed After fixing to the rotating shaft 12 by using the clap 20, the shift lever 37 of the shift portion 36 is moved to the gear shift setting groove 38 located on the opposite side, the gear portion ( The transmission gear 34 of 35 is engaged with the second gear 33 so that the lateral drive screw 50 rotates by the rotational force generated by the electric motor M2.

As such, when the lateral drive screw 50 is rotated, the guide body 62 coupled thereto is moved forward in the lateral direction by a screw method, such that the second drive shaft 60 moves forward. .

When the second driving member 60 is moved forward, the drum processing unit 80 coupled to the front end thereof is moved forward and positioned inside the drum fixed by the clamp 20, and the bite is placed on the inner circumferential surface of the drum. When the rotation of the electric motor M2 is rotated in the opposite direction in a state in which the bite is in contact with the inner circumferential surface by adjusting the position of the bite, the lateral driving screw 50 by the second gear 33 is formed. ) Is reversely rotated, and as a result, the second driving shaft 60 is moved backward while the guide body 62 coupled to the screw is moved backward.

Therefore, the inner peripheral surface is cut by the bite of the drum processing unit 80 coupled to the front end while the second driving shaft 60 moves forward and backward due to the rotation of the lateral drive screw 50.

As described above, the disk or the drum is fixed and rotated by the clamp 20 coupled to the rotating body 12, the rotational force by the electric motor (M2) to the transmission portion 36 and the gear portion (35). And the surface of the disk or drum fixed by the disk processing unit 70 coupled to the first drive shaft 40 and the drum processing unit 80 coupled to the second drive shaft 60 is cut. Accordingly, the bending and surface roughness due to abnormal wear of the disk and drum surface can be eliminated, and in particular, the user can arbitrarily adjust the surface roughness freely to obtain the best frictional force, thereby increasing the braking force of the vehicle due to the increased frictional force. It can be improved.

For example, the grinding machine 1 according to the present invention, as mentioned above, can be driven in the automatic manner using the gear unit 35, the rotational force by the electric motor (M2), of course, if necessary shift The shift lever 37 of the section 36 is positioned at the center of the gear shift setting groove 38 so that the shift gear 34 of the gear section 35 is not engaged with the first and second gears 32 and 33. In the neutral state, the first and second handles 44 and 51 coupled to the longitudinal drive screw 42 and the lateral drive screw 50 are directly rotated by the user and manually operated by a manual method. It can be driven.

As such, by using the vehicle brake disk and the drum polishing machine according to the present invention, it is possible to combine the disk and drum required for surface processing in a stable and stable state, and the precision according to the surface processing, in particular, the surface roughness can be arbitrarily selected by the user. Since it can be set freely, the frictional force is increased to improve the brake braking force.

In addition, the present invention is to make a pair of bites for processing the disk surface, and to allow the free space in the front, rear, left and right directions to adjust the spacing in the state spaced apart from each other by a predetermined distance, the surface processing It is possible to improve the workability and stability, and to ensure the excellent quality according to the reuse of the disk and drum by the surface polishing process, it is possible to obtain an economic effect to extend the service life as possible.
