Bicycle valve core grinding device

Abstract

the invention relates to the field of grinding machines, in particular to a bicycle valve core grinding device which comprises a base, and further comprises a feeding assembly, a rotary clamping assembly, a first grinding assembly and a second grinding assembly, the rotary clamping assembly is fixedly arranged on the base, the feeding assembly is fixedly arranged on the base and is positioned at the feeding end of the fixed rotating assembly, the first grinding assembly is fixedly arranged on the base and located on one side of the working end of the rotary clamping assembly, the second grinding assembly is fixedly arranged on the base and is located on the other side of the working end of the rotary clamping assembly, and the output ends of the first grinding assembly and the second grinding assembly are oppositely arranged. According to the bicycle valve core grinding device, a sucker assembly sucks a produced valve core and sends the valve core into the interior of the rotary clamping assembly, a chuck clamps the tail end of the valve core, a rotating assembly starts to drive the frame head to rotate, grinding heads on the first grinding assembly and the second grinding assemblyin the rotating process alternately grind the valve core, and the situation of a flat tire is reduced after the valve core is ground.

Description

technical field [0001] The invention relates to the field of grinding machines, in particular to a bicycle valve core grinding device. Background technique [0002] Bicycles, introduced into China from western countries, are also called bicycles or bicycles. They are usually small land vehicles with two wheels. Now bicycles are spread all over the world and enter every household. They are the most common means of transportation for people. Stepping on the pedal as the power is a green and environmentally friendly means of transportation. [0003] Bicycle tires are an indispensable part of bicycles. Bicycle tires are divided into many types, including tires with or without liners, non-pneumatic tires and ordinary tires. Generally, ordinary tires are equipped with valves, and the valves are located inside. With valve core. [0004] The function of the valve core: the valve core on the inflatable inner tube acts as a one-way valve, which only allows the gas to enter and preve...

Problems solved by technology

[0004] The function of the valve core: the valve core on the inflatable inner tube acts as a one-way valve, which only allows the gas to enter and prevents the gas from leaking out, which is convenient for air intake and ensures the sealing of the inflatable inner tube. However, if the surface of the valve core is not enough during production Smooth and clean tires will cause the tires to run slowly. If the tires are in the state of running slowly for a long time, it will cause the tires to be airless. The airless tires will increase the contact surface with the ground and increase the resistance. The finish of the valve core is very important
