A consignment trolley used for step-by-step conveying and cleaning of axle housing parts

Abstract

The invention discloses a consigning trolley for stepping type conveying and axle housing part cleaning part cleaning. The consigning trolley comprises positioning pins, positioning sheets, a trolley body assembly, flat wheel assemblies, V wheel assemblies and bearing assemblies with waterproof seats. The two positioning pins are arranged on installation concave bars of the left side and the right side of the upper portion of the trolley body assembly respectively and are symmetrically arranged on the two sides of a second center line. In addition, the two positioning sheets are installed on an installation seat on the upper portion, and symmetrically arranged on the two sides of the second center line as well. The two flat wheel assemblies are arranged at the lower end of the left side of the trolley body assembly and are symmetrically arranged on the two sides of a first center line. The two ends of a roller shaft of each flat wheel assembly are each provided with one corresponding bearing assembly with the waterproof seat. In addition, the two V wheel assemblies are arranged at the lower end of the right side and symmetrically arranged on the two sides of the first center line, and the two ends of a roller shaft of each V wheel assembly are each provided with the corresponding bearing assembly with the waterproof seat. Totally, the eight bearing assemblies with the waterproof seats are arranged and are fixedly connected to the lower portion of a connecting plate B in the trolley body assembly through fasteners.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a consignment trolley used on a conveying line, in particular to a consignment trolley used for step-by-step conveyance and cleaning of axle housing parts of a "tractor front drive steering axle". Background technique [0002] "Tractor front drive steering axle" axle housing parts, referred to as axle housing parts, such as figure 1 It is shown that it is a material with a long one-way size, and it is necessary to install important moving parts such as the main deceleration assembly, the terminal deceleration assembly, and the steering system assembly in the inner cavity α when it is used. Therefore, the axle housing part 1 In particular, the cleaning quality (cleanliness) of the inner cavity α will directly determine the working quality and service life of the front drive steering axle components of the final product. This is because: [0003] 1) During the casting proces...

AI Technical Summary

Problems solved by technology

[0010] 1) Although the above-mentioned "chain stepping" conveying system is equipped with rolling slides to reduce the load-carrying weight of the conveying chains on both sides, prevent its running resistance from increasing, and avoid overloading, however, the system needs to convey Multiple axle housing parts run at the same time, that is, they need to meet the "heavy load" and "multi-station" axle housing parts transportation requirements at the same time. Therefore, in the actual use process, it is difficult to realize its light and smooth chain stepping operation. On the contrary, it is prone to quality problems such as difficult control of the stepping process (step distance) and poor stepping operation.

In addition, because the cleaning machine only uses fixed nozzles to flush the inner cavity of the axle housing at both ends of the axle housing parts, that is, the nozzles do not go deep into the inner cavity of the axle housing for cleaning, therefore, the parts of the axle housing on the axle housing bracket Placement does not have strict positioning and placement requirements, so it is difficult to apply to the need for probes to be inserted into the inner cavity of the axle housing for cleaning

[0011] 2) Although the above-mentioned "step-by-step" conveying system can meet the "heavy load" and "multi-station" axle housing parts delivery requirements at the same time, it needs to carry multiple axle housings at the same time during its step-by-step operation Parts implement heavy load "jumping" lifting, that is, "lifting, translational stepping, falling" operation, not only the stepping operation has a large lifting range, but also the structure is thick, large and powerful, and it needs to occupy a large activity space. For the application of "non-lifting" step-by-step conveying with limited space and smooth operation, the conveying system still has certain limitations, and it is difficult to meet its application

[0018] In summary, according to the existing known technology, in order to further improve the cleaning quality of "axle housing parts" and the lightness, stability and reliability of stepping operation, "a consignment for step-by-step transportation and cleaning of axle housing parts" As far as small cars are concerned, there is currently no known technology that can be read and used for reference. Therefore, this is still a practical problem that needs to be solved
