Processing and preparation method for multi-variety v-shaped positioning axle housing cleaning consignment trolley

Abstract

The invention discloses a machining and preparing method for a cleaning and conveying trolley for multiple varieties of V-shaped positioning axle housings, and belongs to the field of mechanical manufacturing. According to the machining and preparing method, a same-period matched study is implemented while a technical scheme of the cleaning and conveying trolley for multiple varieties of V-shaped positioning axle housing components is studied, it can be ensured that the multiple varieties of V-shaped positioning axle housing components are used on the cleaning and conveying trolley, and the application range is widened; and during variety changing, involved positioning and limiting assembly machining and preparing are feasible and reliable, and convenience and accuracy are achieved; and the phenomenon of forced demounting and rewelding during changing can be avoided, and the rapid changing needed during actual production is met. The method is clear, simple and practical, preparing is easy, and the popularized application value is achieved.

Description

Technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a cleaning consignment trolley used on a step-by-step conveying line, and in particular to a processing and preparation method for cleaning consignment trolleys of multiple types of "V-shaped positioning" axle housings. [0002] The multi-variety refers to the different types of axle housing parts formed by the "V-shaped positioning" axle housing parts due to changes in the dimensions of the "positioning and limiting"; the "V-shaped positioning" refers to this type of parts series The positioning method of "V-shaped at both ends" is adopted; the processing and preparation method refers to the positioning and limiting components involved when the type of parts needs to be changed and positioned and placed on the "cleaning and consignment trolley". How to implement its processing and preparation methods. Background technique [0003] The axle housing parts of the "Tractor Front Driv...

AI Technical Summary

Problems solved by technology

[0009] Note: After the trolley is finished, it is only suitable for cleaning a single type of "V-shaped positioning" axle housing parts, and cannot be used for different types of "V-shaped positioning" axle housing parts due to changes in "positioning and limit dimensions". Variety of Cleaning Used

That is to say, when it comes to the four dimensions of the axle housing, "the distance L1 between the two positioning outer circle sides, the positioning outer circle ∮d, the widest distance between the mounting holes L2, and the distance H from the centerline of the axle housing to the pipa surface", one or more When there are two changes, the cleaning of the axle housing parts cannot be reliably carried out on the above-mentioned completed trolley.

[0010] Continued explanation: In view of this situation, if it is necessary to change a certain type of axle housing for cleaning, it is necessary to improve the manufactured trolley, such as "distance between two positioning outer circles side end faces L1, positioning outer circle ∮d, installation hole maximum If the three dimensions of the wide spacing L2" change, the "left V-shaped positioning component 3, the plane limit component 4, and the right V-shaped positioning component 5" welded to the car body component 2 need to be removed and cleaned one by one. , and remade according to the changed "size", especially afterward, it needs to be welded to the required position on the car body assembly 2. In this way, it is not only time-consuming and difficult to quickly change the variety to meet the needs of rapid change in actual production, but also "Forced dismantling and re-welding" is also required, which can easily damage the car body. In addition, if there are dozens of such finished cars on the step-by-step conveyor line, the workload of improving the variety change will be greater and the time will be longer

[0011] Further explanation: Even if the improvement of the above-mentioned trolley is completed, the improved trolley is still only suitable for cleaning the axle housing parts of one type. Improve the process, although it is possible to do so, it is not desirable or necessary
