specific Embodiment approach

[0019] The specific embodiment of the present invention is as follows: first, the tire is placed on the circular tray 12, the first cylinder 11 lifts the circular tray 12 upwards to the place where the polishing sheet 8 is flush with the inner surface of the tire, the air pump 1 is turned on, and the air flow passes through The hollow main rod 4 finally flows into the telescopic rod 7. When the air pressure reaches a certain value, the telescopic rod 7 moves away from the branch pipe 6 under the push of the airflow, until the grinding sheet 8 contacts and squeezes the inner wall of the tire, supporting the tire rise. Simultaneously, telescopic rod 7 is in motion process, and the spring 9 that connects telescopic rod 7 is stretched, stretches out outside branch pipe 6 until the air hole 10 on the telescopic rod 7, and the air-flow in branch pipe 6 overflows through air hole 10, with this Control the air pressure inside the hollow main rod 4 and the branch pipe 6 to make the gri...

Abstract

The invention relates to a device for grinding the inner wall and the outer wall of a tire, and belongs to the technical field of devices for grinding workpiece edges or inclined faces or burrs. The device comprises a rack. A motor, an air pump, a first air cylinder and a grinding device are arranged on the motor, and the motor is connected with a first gear. The bottom end of the air pump is connected with a hollow main rod, a second gear is connected to the hollow main rod, the tail end of the hollow main rod communicates with branch pipes, a telescopic rod is connected in each branch pipe,and one end of each telescopic rod is connected with a grinding piece. The first air cylinder comprises a first piston rod and a cylinder barrel, the first piston rod is connected with a round tray, the cylinder barrel is connected with second air cylinders, the bottom of each second air cylinder is connected with a supporting seat, a rocker bar is hinged to the top end of each supporting seat, the middle end of each rocker bar is connected with a piston rod of the corresponding second air cylinder, and a fixed baffle is arranged at the top end of each rocker bar. An outer grinding device comprises a grinding knife and a sliding block. According to the technical scheme, the problems that during manual grinding of the inner wall and the outer wall of the tire, time and labor are wasted, andefficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of grinding workpiece edge or bevel or burr device. Background technique [0002] With the rapid development of my country's national economy, it has effectively promoted the development process of my country's road transportation and automobile industry. The number of automobiles has increased year by year, and the use and consumption of automobile tires have also increased rapidly. A series of waste tires pollute the environment, and the recycling of tires can save a lot of rubber materials and resources. [0003] However, at present, the grinding of waste tires can only be done manually with a hand-held grinding blade, which is not only time-consuming and laborious, but also inefficient. The quality of grinding is greatly affected by human factors, which will directly affect the quality of the tires. Safe use problem, Here it is the weak point that existing technology exists.
