As shown in fig. 1 to 5, an apparatus 100 for automobile accessory polishing process includes: the polishing device comprises a base 101, a first fixing mechanism 10, a second fixing mechanism 20, a flexible polishing assembly 30 and a power mechanism 40.
The base 101 serves as a main support structure for the apparatus 100 for automobile parts polishing processing to support other respective apparatuses and to allow the respective apparatuses to be assembled as a whole. The first fixing mechanism 10 is used to position one end of the exhaust pipe fitting. The second fixing mechanism 20 is used to position the other end of the exhaust pipe fitting. As a specific embodiment, the first fixing mechanism 10 and the second fixing mechanism 20 are both expansion clamps that expand outward by extending into the exhaust pipe fitting to clamp the exhaust pipe fitting.
The flexible buffing assembly 30 is used to buff the outer surface of the exhaust fitting. A flexible buffing assembly 30 is wrapped around the periphery of the exhaust fitting. The power mechanism 40 is used to drive the flexible polishing assembly 30 to rotate around the exhaust fitting for polishing.

The power mechanism 40 includes: a power motor 41, a first transmission shaft 42, a second transmission shaft 43, a universal joint 44, a first driving pulley 45 and a second driving pulley 46.
The power motor 41 is mounted to the base 101. The power motor 41 drives the first transmission shaft 42 to rotate. The universal joint 44 connects the first transmission shaft 42 and the second transmission shaft 43. The universal joint 44 is arranged such that the axes of rotation of the first and second drive shafts 42, 43 may be arranged non-colinear. The rotation axis of the first transmission shaft 42 is parallel to the extending direction of one end of the exhaust pipe fitting based on the shape setting of the exhaust pipe fitting. The rotational axis of the second transmission shaft 43 is parallel to the extending direction of the other end of the exhaust pipe fitting. The axis of rotation of the first drive shaft 42 is oblique to the axis of rotation of the second drive shaft 43.
A first drive pulley 45 is mounted to the first driveshaft 42. A second drive pulley 46 is mounted to the second drive shaft 43.
The first driving pulley 45 drives the first head member 31 to rotate through belt transmission. The second drive pulley 46 is belt driven to rotate the second end member 32.
Since the first transmission shaft 42 and the second transmission shaft 43 rotate at the same speed, the first head piece 31 and the second head piece 32 can rotate at the same speed, thereby ensuring that the two ends of the polishing element 33 rotate at the same speed.
As a preferred embodiment, the apparatus 100 for automobile parts polishing process further includes: a first moving device 50 for moving the first fixing mechanism 10 and a second moving device 60 for moving the second fixing mechanism 20.

The second motion device 60 includes: a second motor 61, a second guide rail 62, and a second slide table 63. The second rail 62 is mounted to the base 101. The second fixing mechanism 20 is mounted to the second slide table 63. The second slide table 63 slides along the second guide rail 62. The second motor 61 drives the second slide to move relative to the base 101 through the lead screw nut transmission mechanism.
As a specific embodiment, the direction in which the first slide table 53 slides with respect to the first guide rail 52 is parallel to the rotational axis of the first transmission shaft 42. The direction in which the second slide table 63 slides with respect to the second guide rail 62 is parallel to the rotational axis of the second transmission shaft 43.
As a specific embodiment, the apparatus 100 for automobile parts polishing process further includes: two axial displacement mechanisms 70 for dithering the flexible polishing assembly 30 in the axial direction of the exhaust tube fitting.
When the polishing quality requirement is high, the axial displacement mechanism 70 can be arranged to enable the flexible polishing assembly 30 to generate a certain displacement along the axial direction, so that the polishing quality is improved. The axial displacement mechanism 70 may not be provided when the polishing quality requirement is relatively low.
Two axial displacement mechanisms 70 are mounted to the first and second slide tables 53 and 63, respectively. The axial displacement mechanism 70 includes: a pin rod. The first and second head pieces 31 and 32 are each formed with a wave ring groove 311.

The axial direction of the pin inserted into the first head piece 31 is perpendicular to the axial direction of the first head piece 31. The axial direction of the pin inserted into the second head member 32 is perpendicular to the axial direction of the second head member 32. The belt transmission mode is adopted, and the belt transmission is not influenced when a certain axial movement of the belt pulley is caused due to the small axial shaking displacement.
As an alternative embodiment, the first driving pulley and the second driving pulley may be arranged to be axially slidable, and the first driving pulley and the second driving pulley may be synchronously displaced by the same amount as the flexible polishing assembly by the axial displacement mechanism.
As a specific embodiment, the axial displacement mechanism 70 further includes: and a cylinder 71. The cylinder 71 pushes the pin rod to move so as to be inserted into the wave ring groove 311 or to be extracted out of the wave ring groove 311.
As a specific embodiment, the shape and the circumferential angular position of the wave-shaped ring groove 311 formed by the first and second head members 31 and 32 are identical so that the axial displacement mechanism 70 pushes the first and second head members 31 and 32 to simultaneously advance and retract.
As a specific embodiment, the first and second head members 31 and 32 have the same structure, and the wave ring grooves 311 of the first and second head members 31 and 32 are arranged in a periodic wave structure.
As a specific embodiment, the first transmission shaft 42 and the second transmission shaft 43 are each rotatably mounted to the base 101 through a bearing housing.
In a preferred embodiment, the polishing element 33 comprises a plurality of longitudinal polishing strips 331 and a plurality of transverse polishing strips 332. The plurality of transverse soft strips 332 connect the plurality of longitudinal soft polishing strips 331 as a whole to form a cloth-like structure. The polishing element 33 wraps around the exhaust fitting by means of a resilient band. The longitudinal polishing soft strip 331 is made of a flexible porous foam material added with a polishing material. The burnishing element 33 may be attached to the surface of the exhaust fitting by a resilient clip, although other means of attaching the burnishing element 33 to the surface of the exhaust fitting may be used. During the polishing process, the polishing element 33 may be sprayed with a polishing solution to enhance the polishing effect.
As a specific embodiment, the first and second header members 31 and 32 are made of PP material. The first and second head pieces 31 and 32 are arranged in an open shape to surround the exhaust pipe fitting by means of a clip or snap connection. The first and second head members 31 and 32 have a certain flexibility, and can be easily set to the outer periphery of the exhaust pipe fitting by enlarging the size of the inner hole by deformation at the time of installation. The closed loop can then be formed by means of a snap clamp.
