Device and method for non-destructive disassembly and assembly of the valve core of the gear cylinder of the truck

Abstract

The invention discloses a device and method for non-destructive disassembly and assembly of a gear cylinder gas circuit valve core of a truck, comprising an upper valve core extraction device and a lower valve core extraction device; the upper valve core extraction device includes a first semi-cylindrical wall ( 3), bolt hole (4), second semi-cylindrical wall (6), cylindrical jacket (10), connecting bolt (11), screw rod (12) and tapered screw rod (15); the lower valve core removal device Including the first hook body (22), the first hook body (23), the second hook body (25), the second hook (26), the hook body jacket (27) and the hook rod (28); Reasonable and effective force applied to the spool, the upper spool removal device can easily take out the control valve of the gear cylinder, and the lower spool removal device can easily take out the main air valve of the gear cylinder, ensuring the integrity of the spool taken out to the greatest extent and ensuring the valve core There is no damage after being taken out, and the valve core can be used after being cleaned, which effectively reduces the cost of new products.

Description

technical field [0001] The invention relates to a device and a method for disassembling and assembling a gear cylinder air circuit valve core for a vehicle, in particular to a non-destructive disassembling device and method for a truck gear cylinder air circuit valve core. Background technique [0002] The truck is one of the main vehicles of the Ministry of Transport for the transportation of goods. It is mainly responsible for the transportation of main and auxiliary raw materials in the factory area, including water slag, coke, asphalt ash, dry slag, gas ash, hot briquettes, lime powder and other materials. Due to the limitation of the roads in the factory area, vehicles stop and start more frequently, and the number of shifts is relatively high. According to statistics, the working intensity of the shift mechanism of the vehicle is 1800 times / 100KM, and the main working medium of the shift mechanism is compressed air. Contains a lot of water, plus impurities such as rust...

AI Technical Summary

Problems solved by technology

[0006] a. Due to the insufficient strength of the removal tool, it often happens that the valve core cannot be removed, especially when the valve core wall is covered by impurities 201 at the O-ring, impurities 202 between the air valve and the inner wall of the housing, and impurities 203 at the air seal When pasted on the inner wall of the gear cylinder housing 600

[0007] b. Occasionally, tools damage the air inlets at the middle and bottom of the air valve, making the air valve unable to be repaired and used, and can only be replaced as a whole, resulting in an increase in maintenance and use costs

[0008] c. Deformation of the precision parts where the air valve contacts the solenoid valve, and damage to the key parts of the air valve, making it impossible to continue to use
