Description

Technical Field:

[0001] This application relates to the technical field of loader assembly jigs, and in particular to a crawler skid-steer loader frame assembly jig. Background Art:

[0002] A skid-steer loader, also known as a skid-steer loader, multi-functional engineering vehicle, or multi-functional engineering machine, is a special wheeled chassis device that realizes vehicle steering by using the linear speed difference between the two side wheels. It is mainly used in occasions with narrow working sites, uneven ground, and frequent changes in work content. It is applicable to infrastructure construction, industrial applications, dock loading and unloading, urban streets, residences, barns, livestock houses, airport runways, etc., and can also be used as an auxiliary device for large engineering construction machinery. There are two types of walking methods for skid-steer loaders: wheeled and crawler type. As Figure 4 shown, the skid-steer loader box generally includes a U-shaped frame, connecting legs provided on both sides of the lower part of the U-shaped frame, and side plates on the upper edge of the U-shaped frame.

There is also a power cylinder 23 for driving the activities of the X-direction horizontal plate 3, the mounting plate 5, the movable seat 10 and the second leg 11.

[0041] The connecting support leg is fixed by using the vertical plate and the movable seat, and then the U-shaped frame is positioned and fixed by the limit post on the first support leg, the second support leg and the support seat. The rotation and pressing cylinder and the tightening cylinder are used to fix the side plate. The assembly of the U-shaped frame, the connecting support leg and the side plate is centralized on a tooling, which saves costs and greatly improves the assembly efficiency and reduces the labor intensity of workers.
