Description

Technical Field

[0001] The utility model belongs to the technical field of polishing operations, and in particular relates to a double-cloth wheel polishing power head. Background Art

[0002] During polishing operations, the hardness of the polishing wheel directly impacts polishing quality and production efficiency. Softer wheels produce higher polishing quality but lower production efficiency, while harder wheels produce higher efficiency but lower polishing quality. Therefore, in actual production, to ensure both polishing quality and efficiency, a harder and softer wheel are often used in combination.

[0003] In the existing automated polishing operation of luggage rack products, a robot is generally used to grab a single cloth wheel polishing power head to polish the luggage rack products. In addition, due to the high quality requirements of the product appearance, a single set of softer cloth wheels is generally used for production, which has low production efficiency. If production efficiency needs to be improved, two robots are required to grab harder cloth wheels and softer cloth wheels to polish the products in turn, which has high production costs. Utility Model Content

[0004] The utility model aims at solving the above problems in the prior art and proposes a double-cloth wheel polishing power head which can reduce production cost and improve production efficiency.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1-4 As shown, the utility model provides a double cloth wheel polishing power head, comprising:

[0030] Rack 100;

[0031] The left cloth wheel 110 and the right cloth wheel 120 are both arranged on the frame 100;

[0032] The motor 130 is mounted on the frame 100 and connected to the left cloth wheel 110 and the right cloth wheel 120 via the transmission assembly 170. The motor 130 drives the left cloth wheel 110 and the right cloth wheel 120 to rotate simultaneously.

[0033] The robot arm 140 is connected to the frame 100 , and the frame 100 is driven to move by the movement of the robot arm 140 so that the workpiece contacts the left cloth wheel 110 and the right cloth wheel 120 and completes the polishing operation.

[0034] That is to say, the polishing equipment provided in this embodiment integrates two cloth wheels at the same time. The left cloth wheel 110 and the right cloth wheel 120 can be set as a softer cloth wheel and a harder cloth wheel. The robot only needs to grab one polishing equipment to polish the product successively through the harder cloth wheel and the softer cloth wheel. While improving production efficiency, it also ensures the surface quality of the product and reduces production costs.

[0035] Preferably, the robot arm 140 is installed on the top of the frame 100 , and the frame 100 is opened downward, and the left cloth wheel 110 and the right cloth wheel 120 are located at the opening at the bottom of the frame 100 .

[0036] Furthermore, the left cloth wheel 110 and the right cloth wheel 120 are arranged symmetrically and a distance is left between them and the inner cavity of the frame 100 to form an installation space. The motor 130 is arranged in the installation space and forms an upper and lower arrangement structure with the left cloth wheel 110 and the right cloth wheel 120, which improves the space utilization rate of the equipment, reduces the size of the equipment, and thereby improves the flexibility of the robot arm 140 when performing polishing operations after grasping, thereby indirectly improving the polishing effect of the product.

[0037] Preferably, it also includes a main shaft 150, and the left cloth wheel 110 and the right cloth wheel 120 are respectively installed on the two main shafts 150, and the motor 130 drives the two main shafts 150 to rotate through the transmission assembly 170 to realize the rotation of the left cloth wheel 110 and the right cloth wheel 120.

[0038] Preferably, a fixing plate 160 and a transmission assembly 170 are respectively provided on both sides of the frame 100, and both ends of the main shaft 150 are respectively connected to the transmission assembly 170 and the fixing plate 160 to ensure the stability of the main shaft 150 after installation.

[0039] The transmission assembly 170 is composed of a driving pulley 171, a belt 172, and a driven pulley 173. The output shaft of the motor 130 is connected to the driving pulley 171. The ends of the two main shafts 150 are both equipped with driven pulleys 173. The driving pulley 171 and the driven pulley 173 are connected by a belt 172.

[0040] When the motor 130 is started, its output shaft drives the active pulley 171 to rotate, and the active pulley 171 drives the driven pulley 173 to rotate through the belt 172. The driven pulley 173 then transmits the rotational force to the main shaft 150, thereby driving the cloth wheel to rotate. Since the left and right cloth wheels are respectively connected to the motor 130 through their respective driven pulleys 173, they can achieve synchronous rotation, ensuring the consistency of the polishing process.

[0041] Preferably, a main bearing mounting seat 180 is also provided on the frame 100, and one end of the main shaft 150 is passed through the main bearing mounting seat 180 through at least a pair of bearings. The main bearing mounting seat 180 is located between the driven pulley 173 and the polishing wheel. At the same time, the other end of the main shaft 150 is mounted on the fixed plate 160 through the secondary bearing mounting seat 190, and the main shaft 150 is connected to the secondary bearing mounting seat 190 through the inner and outer conical surfaces, thereby effectively supporting both ends of the bearing and ensuring the stability of the cloth wheel during high-speed rotation through the bearing.

[0042] Preferably, it also includes polishing spray guns 200, of which at least two are provided and are respectively arranged on the side of the frame 100, and at least one polishing spray gun 200 is arranged toward the left cloth wheel 110 and the right cloth wheel 120, which can spray polishing liquid or polishing powder toward the cloth wheel during the polishing process to help improve the polishing effect.
