Description

Technical Field

[0001] The utility model relates to the technical field of armrest base processing, and particularly relates to an automatic grinding and polishing device for an armrest base. Background Art

[0002] The armrest base is an important part of the armrest accessories, also known as the armrest pedestal. The armrest accessories are specifically used for the armrests of mechanical seats in engineering vehicles (such as lawn mowers, harvesters, cranes, etc.). Such armrest accessories are ergonomic engineering seat accessories, which are flexible to operate, comfortable, and are applied to vehicles such as forestry machinery, construction machinery, and agricultural machinery, special vehicles, vehicles in public transportation (subways, high-speed rails, etc.), forklifts for logistics transportation, and seats in workstations. The armrest base is usually cast from strong metal. During the processing of the armrest base, grinding the base is a necessary processing method. Through grinding and polishing, the micro defects and oxide layers on the surface of the armrest base can be removed, exposing a more solid and durable metal material, which helps to extend the service life of the armrest base and reduce damage caused by wear or corrosion. At the same time, polishing can also reduce the surface roughness, make its surface smooth and uniform, and reduce the noise and vibration generated by friction, thereby improving the comfort of use.

[0003] However, in the prior art, the polishing method for the base is to use an operator to hold a polishing device or polishing material to polish the surface of the base. However, manual polishing has low efficiency, the surface smoothness is not uniform enough, and there are many grinding blind spots, so the armrest base cannot be fully and comprehensively polished.

Specific embodiments

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] An embodiment of the present utility model discloses an automatic grinding and polishing device for an armrest base.

[0026] The present utility model provides an automatic grinding and polishing device for an armrest base as shown in Figures 1-3 which includes a frame 1 and a feeding area connected and arranged on the side of the frame 1. At the top of the frame 1 and near one end of the feeding area, a controller 17 is fixedly arranged. Inside the feeding area, a plurality of clamping cylinders 2 are arranged. In the middle of the inside of the frame 1, two symmetrically arranged conveyor belts 3 are fixedly arranged. The two conveyor belts 3 are arranged in an up-and-down stacked manner. The ends of the two conveyor belts 3 extend into the feeding area and are arranged in cooperation with the plurality of clamping cylinders 2;

[0027] On both sides of the inner wall of the frame 1 and near one end of the feeding area, abrasive belt machines 4 are fixedly arranged. On the side of each of the two abrasive belt machines 4, a polishing machine 5 is arranged. At the bottom of the inner wall of the frame 1 and below the conveyor belt 3, a first motor 6, a second motor 7 and a third motor 8 are arranged in sequence;

[0028] At the top of the third motor 8, a discharge base 9 is arranged. On both sides of the discharge base 9, positioning cylinders 10 are arranged. On the inner wall of the frame 1 and at the end far from the feeding area, a semi-circular abrasive belt machine 11 and a semi-circular polishing machine 12 are arranged. A dust extraction fan 16 is fixedly arranged through the side of the frame 1.

[0029] In order to enable the material to flow out stably after polishing and grinding, as shown in Figures 2-3As shown, the outer walls of the two conveyor belts 3 are provided with a first double-axis cylinder 13, the end of the output shaft of the first double-axis cylinder 13 is fixedly provided with a second double-axis cylinder 14, the lower end of the first double-axis cylinder 13 is fixedly provided with a material guide plate 15, and the lower end of the outer wall of the frame 1 is provided with a discharge hole which is matched with the material guide plate 15.

[0030] Before grinding, the armrest base is placed in the feeding area, and the armrest base is clamped by multiple clamping cylinders 2, and then the conveyor belt 3 is opened by the controller 17, and then the multiple clamping cylinders 2 are loosened to allow the armrest base to enter between the two conveyor belts 3, so that the conveyor belts 3 convey the armrest base. During the conveying process of the armrest base, the sanding machines 4 on both sides of the conveyor belts 3 grind the side walls of the armrest base. At the same time, the armrest base continues to move, and the polishing machine 5 effectively polishes the armrest base. After both sides of the armrest base are polished, during the polishing process, the polishing machine 5 advances with compensation after each material is polished to improve the polishing effect, and starts from after the polishing of the side walls of the armrest base is completed. The conveyor belt 3 falls down, and the motor 2 pushes the handrail base to fall onto the discharge base 9. At this time, the two positioning cylinders 10 clamp the handrail base, and then the first motor 7 is retracted, and the semicircular sanding machine 11 grinds the front section of the material, and then the third motor 8 is retracted and the discharge base 9 is rotated. At this time, the semicircular polishing machine 12 polishes the front section of the material, and compensates and advances after polishing once. At this time, the material is completely polished as a whole, and then multiple positioning cylinders 10 are loosened, and the first double-axis cylinder 13 is started and drives the second cylinder 14 to move to the top of the material, and then the second cylinder 14 is started, and the first cylinder 13 is retracted, so that the material moves to the guide plate 15, so that the material flows out through the discharge hole.
